Recently, the market supervision departments in many places issued a notice on the unqualified food sampling list. The Paper combed and found that it involved many problems such as pesticide residues and microbial pollution. The market supervision department has carried out verification and disposal work.

　　It is noteworthy that coliforms were detected in tableware and rice noodles in the unqualified sampling list of several batches of food published by Tai ‘an Municipal Market Supervision Administration and Baise Municipal Market Supervision Administration.

　　Why are coliforms detected in tableware and rice noodles? Kai Zhong, deputy director of Kexin Food and Nutrition Information Exchange Center, said that coliforms mainly come from the intestines of warm-blooded animals, but they are widely distributed in nature. Dishes, rice noodles and so on have coliforms exceeding the standard, mostly because of secondary pollution.

　　Many enterprises were found to contain coliforms in their products.

　　On July 5th, Tai ‘an Municipal Market Supervision Administration issued the information circular on food safety sampling inspection (hereinafter referred to as the circular), which disclosed problems such as excessive pesticide residues and microbial pollution.

　　According to the notice, coliforms were detected in the tableware plates of Fuchunyuan Restaurant in Taishan District and Shandong Xiaolongxiao Jiutian Catering Management Co., Ltd. in Taishan District. According to the national food safety standards, coliforms should not be detected in tableware.

　　Tai ‘an Municipal Market Supervision Administration said in the notice that the market supervision department of the place where the production and operation enterprises are located has ordered the enterprises to find out the product flow, recall and remove the unqualified products, control risks, file an investigation, and analyze the reasons for rectification. The unqualified products involved have been verified and disposed of as required.

　　The Paper combed and found that Baise Municipal Market Supervision Administration had previously released the 26th food safety supervision and sampling information announcement in 2021 on July 1, which also showed that the prepared fresh and wet rice noodles sold by Guangxi Tiandong Weimeijia Agricultural Products Development Co., Ltd. and tianlin county Huaxu Food Co., Ltd. were all found to have coliforms.

　　Kai Zhong, deputy director of Kexin Food and Nutrition Information Exchange Center, said that coliforms are the general name of many bacteria, including Escherichia coli. It is a hygienic indicator bacterium, but it does not lead to disease if it is detected. The higher the detection value, the greater the possibility. Coliform bacteria can be detected in many foods, but as long as there are no pathogenic bacteria, it will generally not cause health hazards. As for the source of coliform bacteria, Kai Zhong said that coliform bacteria mainly come from the intestines of warm-blooded animals, but they are widely distributed in nature. Dishes, rice noodles and so on have coliform bacteria exceeding the standard, mostly because of secondary pollution.

　　According to the interpretation information released by the market supervision department, coliform bacteria is one of the commonly used indicator bacteria for food pollution at home and abroad. The detection of coliform bacteria in food suggests that it is more likely to be contaminated by pathogenic bacteria (such as Salmonella, Shigella and pathogenic Escherichia coli). Excessive coliform bacteria may be caused by the pollution of processing raw materials and packaging materials of products, or the pollution of products by production equipment and environment such as personnel and tools during production, and the incomplete sterilization of products with sterilization technology.

　　A variety of foods were found to have excessive drug residues.

　　In addition to coliform bacteria, some enterprises have been found to have drug residues and other problems. In the notice issued by Tai ‘an Municipal Market Supervision Administration on July 5, the bureau disclosed that the content of "procymidone" in leeks sold by Baxianju Commercial Bank in Ningyang County and Yanzhuang Haiwei Supermarket in Daiyue District was higher than the national food safety standard.

　　The Paper combed and found that in recent food sampling notices issued by many market supervision administrations, the problem of unqualified drug residue detection of enterprise-related products appeared.

　　On July 2nd, the 7th notice of Gansu Provincial Market Supervision Bureau on the sampling inspection of unqualified food showed that chloramphenicol, a drug banned from food animals, appeared in Jinghui brand acacia honey produced by Gansu Jinghui Bee Industry Co., Ltd..

　　On July 5, 2021, Jilin Provincial Market Supervision and Management Department’s 27th notice on unqualified food showed that the carp sold by Fengyun Aquatic Products Company in Automobile Industry Development Zone, Wuchang Fish sold by Yixin Aquatic Products Store in Chaoyang District and snakehead sold by Guo Di Seafood Wholesale Company in Kuancheng Agricultural Products and Aquatic Products Market were all found to exceed the standard.

　　The attachments of the above-mentioned relevant notices show that excessive coliforms are likely to cause intestinal diseases such as dysentery, which may cause symptoms such as vomiting and diarrhea. The pesticide procymidone is irritating to people’s eyes and skin. Long-term consumption of leeks with excessive procymidone residues may cause neurological disorders.

　　The market supervision department reminds consumers that when they find the unqualified products involved in the notice, they can call the 12315 hotline to complain or report.

The relevant matters are hereby notified as follows:

First, attach great importance to the development of brand chain convenience stores

Convenience store is the retail format closest to the lives of ordinary people, and it is an important carrier to meet people’s convenient consumption needs and serve people’s livelihood. In recent years, China’s brand chain convenience stores have accelerated their development, ranking in the forefront of retail formats for many years in a row. However, there are still problems such as insufficient total number of brand chain stores, unreasonable layout, imperfect service functions, and weak management ability. Promoting the development of convenience store brand chain is conducive to improving consumption convenience, improving consumption quality and stimulating consumption potential, which is an important livelihood project. All localities should raise awareness and put the development of brand chain convenience stores into an important work agenda, as an important starting point for implementing the consumption upgrading action plan and promoting the transformation and upgrading of physical retail, and continue to promote it in a planned and step-by-step manner.

Two, combined with the actual situation to determine the key to promote the city

The development of brand chain convenience stores is promoted by cities. According to the working steps of "overall deployment, key promotion and gradual extension", the development of brand chain convenience stores in municipalities directly under the central government, cities with separate plans and provincial capitals should be started first in 2019. On the basis of focusing on promoting these cities, all localities can choose some other cities to promote them in combination with the actual local economic development.

Three, pay close attention to the development of brand chain convenience stores.

Local competent commercial departments should guide the relevant cities to combine the existing work basis, promote branding, chaining and intelligence according to the spirit of the National Conference on the Development of Brand Chain Convenience Stores and the requirements of the Compilation Points of the Work Plan for the Development of Brand Chain Convenience Stores (see Annex), pay close attention to the study and formulation of work plans, and clarify work objectives, work priorities and safeguard measures. It is necessary to organize consulting institutions, think tank experts, industry associations and business representatives to participate in the formulation and demonstration of the plan, so as to improve the pertinence and operability of the plan. Municipalities directly under the central government, cities with separate plans and provincial capital cities should submit their work plans to the Ministry of Commerce before the end of July, and other cities should submit them before the end of September.

Fourth, improve the policy system to support the development of brand chain convenience stores

In view of the outstanding problems affecting the development of brand chain convenience stores, all localities should learn from the practices of Beijing, Xi ‘an, Fuzhou and other cities, focus on deepening the "streamline administration, delegate power, strengthen regulation and improve services" reform and optimizing the business environment, promote the introduction of policies to support the development of brand chain convenience stores, and provide support from the aspects of store location, registration, business license, technology application and supply chain construction, so as to create a good business environment for the development of convenience stores. We must do a good job in the implementation of the policies that have been introduced.

V. Strengthening organizational guarantee

The Ministry of Commerce will establish a three-level linkage working mechanism among departments, provinces and cities, study and formulate the development indicators of brand chain convenience stores from the aspects of convenience store layout, development quality, policy environment and working mechanism, and focus on guiding and promoting municipalities directly under the central government, cities with separate plans and provincial capitals, and make quarterly statistical summary and feedback on the progress and problems. The provincial commerce departments should strengthen the supervision and guidance of relevant cities, clarify the timetable and phased results, compact the work responsibilities, and put the work plan in place. Relevant cities should establish an inter-departmental coordination mechanism and give full play to the role of relevant functional departments and grassroots governments such as districts, counties and streets; Establish a normal communication mechanism between government and enterprises, and listen to and solve problems encountered in enterprise development in a timely manner.

Key points of compiling the development plan of brand chain convenience stores

All localities should scientifically plan the general idea of developing brand chain convenience stores on the basis of in-depth investigation and extensive consultation, combined with local consumption level, consumption characteristics and convenience business development, fully embody the principles of government guidance, market operation, focusing on people’s livelihood and diversified development, organize the preparation of a good work plan, and clarify development goals, main tasks and safeguard measures. The work plan shall be prepared by the competent department of city commerce and approved by the local people’s government. The work plan shall include but not limited to the following aspects:

First, the foundation of development

Focus on the basic situation of the city’s economic and social development, residents’ consumption and convenience business development, and find out the basic base of the main chain brand enterprises of convenience stores in this city. Basic data such as the number of existing brand enterprises, the number of stores, and the basic layout should be fully grasped (the data is as of the end of June 2019) as the baseline for evaluating the progress of the work, and clearly reflected in the work plan in the form of a list.

Brand chain convenience stores refer to convenience stores that operate directly or by joining, with unified image identification, unified store management and control, unified facilities configuration, unified service standards, unified commodity procurement and unified logistics distribution. Enterprises with unified trade names and logos and low standardization in other aspects are not included in the statistical scope of brand chain convenience stores.

Second, the development goals

The development goals are planned in three years, with the end of June 2019 as the benchmark, indicating the goals achieved in each year. Goals can be set in both quantity and quality. In terms of the number of development, it is necessary to make clear the two quantitative goals of brand enterprises and brand chain stores, and at the same time, set the structural development goals from the dimensions of community, distance or population around building a "quarter-hour convenient life service circle" in combination with local reality. It is necessary to highlight the organization and scale orientation, and focus on developing brand chain enterprises with more than 50 chain stores and high reputation and integrity. In terms of development quality, it should reflect the achievements of convenience stores in improving service functions, improving service capabilities and upgrading modernization level.

III. Main tasks

Clear the main tasks of developing brand chain convenience stores, and explain the measures taken in optimizing the layout of convenience stores, improving the convenience service level and strengthening the application of information technology.

Optimize the layout of convenience stores. This paper focuses on the measures to be taken in increasing the resources of convenience stores, expanding the network of brand chain convenience stores and cultivating leading enterprises. According to the situation of commercial facilities, consumption level and consumption habits in different regions, the allocation standards of convenience commercial facilities such as convenience stores should be studied and formulated. Increase the applicable store resources of convenience stores through multiple channels, promote the implementation of the requirement that the area of commercial and comprehensive service facilities in newly-built communities accounts for no less than 10% of the total construction area of the community, and strengthen the security of convenience stores. It is necessary to combine the renovation work of old urban communities, and use the space resources that have been withdrawn from rectification to encourage brand chain convenience stores to settle in. Promote hospitals, universities, stadiums, parks, scenic spots and other public service places to open store resources to brand chain convenience stores. Encourage brand chain convenience store enterprises to transform and upgrade old small shops, grocery stores, canteens and other decentralized convenience stores. Encourage the introduction of well-known brand chain convenience store enterprises with cross-regional development.

Improve the level of convenience services. This paper focuses on the measures to be taken to support convenience store enterprises to expand their business scope, improve service standards, strengthen logistics and distribution capabilities, and transform and improve service environment. It is necessary to support convenience store enterprises to develop their own brand products, expand the sales of fresh food products, provide on-site manufacturing and selling services such as simple meals and drinks, and carry various kinds of convenience life services. Encourage the extension of convenience store business hours and support the opening of 24-hour convenience stores. Support brand chain enterprises to build their own or adopt third-party logistics services, implement joint distribution and centralized distribution, and build an intensive and efficient logistics distribution system. Encourage qualified enterprises to develop food and fresh products production bases and central kitchens, and establish a whole cold chain distribution system. Guide enterprises to benchmark leading enterprises in the industry, establish high-level service standards, optimize processes and enhance service experience. Advocate the concept of green consumption.

Strengthen the application of information technology. This paper focuses on the measures to be taken to support the digital transformation of brand chain enterprises and promote the intelligent and intelligent development of chain operations. Encourage enterprises to integrate chain store resources and online traffic resources, and carry out online and offline integrated operations. Support chain enterprises to apply technologies such as cloud computing and artificial intelligence, and establish a smart supply chain driven by consumer big data, such as commodity procurement, inventory management and order management, to improve operational efficiency. We will promote payment technologies such as self-service settlement, code scanning payment, and face-brushing payment, and encourage the use of commodity management technologies such as digital shelves, electronic price tags, and wireless radio frequency, so as to improve the level of service intelligence and optimize the consumer experience.

Fourth, safeguard measures

In accordance with the requirements of the work notice, safeguard measures are formulated from the aspects of organization and leadership, working mechanism, policy system, follow-up evaluation, etc., the specific division of labor is defined, the work responsibilities are implemented, and the system guarantee is effectively strengthened. Specific encouragement and support policies can be formulated separately after the work plan is determined, but the basic direction should be clearly defined in the plan, and all localities should be encouraged to extend the existing financial support projects to qualified convenience store enterprises. According to the needs of work, all localities can form a "1+N" work system, that is, a work plan, N supporting measures such as encouraging and supporting policies, community convenience business allocation standards, and brand chain convenience store construction guidelines.

A few days ago, the pickup truck market obtained the sales data of pickup trucks in the United States in the first half of 2022. In June 2022, the pickup truck market in the United States sold 233,113 new cars, which was 6.9% lower than that of 250,349 in 2021. From January to June, 1,341,611 new cars were sold, down by 11.4% compared with the same period in 2021. Since the global epidemic in COVID-19 in 2020, the pickup truck market in the United States has been affected by factors such as insufficient production capacity and sluggish economy, and its sales volume has declined for two consecutive years. Up to now, it has continued the previous downward trend in 2022, and it is difficult to recover in the short term.

According to statistics, in the first half of 2022,Ford F-series, Ram pickup truck and Chevrolet Sorod still occupy the top three positions, and GMC Sierra surpassed Toyota Tacoma to rise to fourth place; Chevrolet Colorado,Nissan Frontier and GMC CanyonAfter the replacement of medium-sized pickup trucks, the sales performance is remarkable, and emerging pickup trucks such as Ford Maverick and Hyundai Santa Cruz have injected new vitality into the American market; Rivian R1T, Hummer EV and other emerging electric pickup products began to be delivered gradually.

Ford is the absolute overlord of the pickup truck market in the United States, and F-series pickup trucks sell new cars in June.57,673 vehicles, up year on year.26.3%, but even so, it is difficult to hide the overall decline. Only new cars are sold from January to June.299,345 vehicles, a year-on-year decrease of 17.3%. If the overall downward trend cannot be reversed, the annual sales of Ford F-series pickups will probably fall below the 700,000 mark in 2022.The continuous decline in Ford’s sales has also reduced its lead over Chevrolet and Ram, only less than 40,000 vehicles ahead of the second place, and it may be surpassed with a little carelessness. To this end, Ford promptly followed up the electrification reform, and the F-150 Lightning has now won hundreds of thousands of orders.In the future, Ford will maintain its leading position through multi-dimensional development.

In June 2022, Chevrolet Sorod sold a new car.46,313 vehicles, a year-on-year decline.16.7%, selling new cars from January to June.261,827 vehicles, a year-on-year decline.10.1%, also in an endless decline. Chevrolet Sorod completed the update and change in September 2021, focusing onThe interior and configuration have been upgraded and alsoThe ZR2 cross-country performance version of Sorod was introduced.Make it more competitive in the face of the new Ford F-150 and the new Ram 1500. Chevrolet is also keenly aware of the fiery atmosphere of the current electric pickup market, which was released in January 2022.Silverado EV model,The new car is the second pure electric pickup truck product commonly launched after Hummer EV, and it is also built with the brand-new third-generation pure electric platform Ultium Autoenergy platform, which will provide ideas for the next stage upgrade and development of Chevrolet pickup truck models.

2021 is the highlight moment of Ram pickup.Not only is it a rare brand with year-on-year sales growth in the American market, but it also surpassed Chevrolet Sorod to become the second place. However, after entering 2022, Ram failed to resist the overall market decline. In the first half of the year, only 244,984 new cars were sold, down 21.7% compared with the same period of last year, making it the largest decline among the three American giants. Ram launched Ram TRX last year, which was enough to shake the status of the Raptor’s performance pickup truck, which made the Ford F-150 Raptor feel great pressure. Its first electric pickup truck Ram 1500 EV was also scheduled for 2024, which launched an all-round impact on Ford. However, the update speed and range of the conventional Ram 1500 model are obviously insufficient, and the Stellantis brand after integrated management needs to work harder on pickup trucks.

GMC Sierra and Chevrolet Sorod belong to GM.GMC, as a high-end luxury brand of GM, has always focused on top luxury routes, whether it is pickup trucks. Sierra pickupPreviously, it ranked fifth in the sales list all the year round, but this year it surpassed Toyota Tacoma.Sales in the first half of this year were118,938 vehicles, a year-on-year decline.14.1%。GMC SierraUshered in a new generation in October last year.In order to better fight against Ram 1500, it has been upgraded in all directions on the basis of the previous generation, and the top Denali Ultimate and AT4X versions that break through the previous generation have been introduced. GMC Sierra will also launch an electric version in the future, which is developed based on GM’s new Ulitum platform. The specific production time is tentatively set at around 2023.

ToyotaTacoma is the king of medium-sized pickup trucks in the United States, occupying the throne of the sales champion of medium-sized pickup trucks in the United States all the year round, with a sales volume of 108,648 in the first half of 2022.Car,It fell 22% year-on-year. Tacoma is the only "foreign" product that has achieved great success in the United States. It is more popular than its big brother, Toyota Tantu, and the car is currently in a replacement cycle. It is reported that the next generation model will share the R&D platform with 4Runner, brand-new Hilux, brand-new smooth road and brand-new land patrol, so that Toyota products can be better pushed to the global market, so it is not impossible if the new Tacoma production version of the real car is highly similar to the brand-new smooth road in the future. At the same time,Toyota recently announced its electrification development strategy, including an electric pickup truck product, which is supposed to be Tacoma electric version.

Toyota smooth road,Chevrolet Colorado,Nissan Frontier,Jeep gladiator,Ford Maverick,Several models of Ford Ranger constitute the third group. Among them, Toyota, after upgrading, has made remarkable progress. From January to June, it sold 44,316 new cars, up 1% year-on-year, which not only got rid of the previous continuous decline, but also rushed to the position of the leader of the third group. Chevrolet Colorado also has a good performance this year. Thanks to the renewed enthusiasm of consumers for small and medium-sized pickup trucks, the sales volume of the car reached 44,190 from January to June, up 13.7% year-on-year, and the growth rate in June reached 48.4%. Nissan Frontier has also been reborn due to changes in the market wind direction, with sales of 43,168 vehicles in the first half of the year, with a year-on-year increase of 63.6%.

As the saying goes, people’s joys and sorrows are not connected, so are car sales. At present, small and medium-sized pickup trucks have become a hot spot of consumption again. Jeep Gladiator sold 38,756 vehicles in the first half of the year, down 20.6% year-on-year. Perhaps it was abandoned by consumers because of its rich play attributes and low use value. FordMaverick, as a new compact product launched by Ford for market hotspots, well explains the importance of grasping the outlet. The sales volume of new cars in the first half of the year was 38,753, showing a relatively strong growth momentum, and it is expected to become an important sales pillar of Ford pickup trucks in the future. Ford Ranger, once the leader of the third group, fell to the end of the group this year, with sales of only 33,840 vehicles in the first half of the year, down 42% year-on-year. It seems that it will take time for the new Ranger to truly adapt to the American market.

At the bottom of the list isHonda Ridgeline,Modern Santa Cruz,GMC Canyon andNissan Titan, in which Honda Ridgeline’s sales in June this year increased by 5.5% year-on-year, but the cumulative sales from January to June are still in a state of decline; As a pure pickup truck, Hyundai Santa Cruz’s monthly sales are gradually increasing, even surpassing Nissan Titan and GMC Canyon；. GMC Canyon sold 13,662 vehicles in the first half of the year, up 9.4% year-on-year;Nissan Titan sold 11,212 new cars in the first half of the year, down 36.9% year-on-year. It is still in an endless decline. It is reported that Nissan is preparing to give up Titan pickup trucks and there will be no next-generation models.

In 2019, Tesla Cybertruck reshaped pickup products with its subversive design concept, which opened the prelude to competition in the field of electric pickup trucks. Subsequently, Ford F-150 Lightning, Hummer EV, Rivian R1T, Chevrolet Silverado EV and other heavy models came out one after another, which refreshed people’s understanding of electric vehicle products. At present, Hummer EV and Rivian R1T have officially entered the delivery link. Rivian R1T delivered 1,600 new cars in half a year, and Hummer EV delivered 90 vehicles. At present, all major electric pickup truck models have received huge orders, and the main reason that restricts their sales is that the delivery is delayed due to insufficient production capacity.

　　(Reporter Chen Lili correspondent Luo Lipeng, Ji Hongbao) Less than a month after Chen Mou and female netizen Huang met through the Internet, they developed into online dating and met a tryst. Unexpectedly, her boyfriend Fu found out that Chen Mou was held hostage and demanded 10,000 yuan for "compensation". Yesterday, Fu was discovered by the community patrol police on the way to extort money. At present, Fu has been under criminal detention.

　　Female netizens said that they were deceived and stole money for revenge.

　　Chen Mou, a 21-year-old man, met Hwang through the Internet, and then they started online dating. On August 8, the two met and stayed in Huang’s dormitory. The next morning, their mobile phones were missing. Because Hwang already has a boyfriend Fu, he told Chen Mou to leave quickly.

　　According to Chen Mou, after he left, Hwang suspected that the mobile phone was stolen by him, and felt that Chen Mou cheated and stole money, and he suffered a big loss, so he implicitly told Fu Mou about the situation and asked Fu Mou to get justice for him. Therefore, Fu promised Huang and asked Huang to ask Chen Mou out. Yesterday morning, Chen Mou came to the door of a hotel after receiving a phone call. Fu and several men punched and kicked Chen Mou and asked him to "compensate" 10,000 yuan.

　　Then three people got off at a store, and Chen Mou called home to get the money. When he was about to leave, he was rescued when he met a patrolling policeman. At present, Fu has been detained in criminal detention.

　　In Yongchun Zhihui Valley, Xingchuang Tiandi, Fujian Province, Lin Zhirong, a college student, has grown from an entrepreneurial "Xiaobai" who is responsible for the new media promotion of health tea projects to a maker who runs two tea online stores in partnership, realizing a wonderful "turn" in life.

　　This is due to Zhihui Valley’s "helping hand": under the guidance of Zhihui Valley’s entrepreneurial tutor and Associate Professor Zheng Shuangyang of Jiangxia College, with the help of Zhihui Valley platform resources, Lin Zhirong’s project signed a number of tea gardens, and after only six months of operation, it has achieved profitability. In January this year, the turnover of a single store exceeded 100,000 yuan. This is a microcosm of the construction of Xingchuang Tiandi in Quanzhou. Up to now, the city has cultivated 37 star-creation worlds at all levels, including 13 national ones, ranking first in the province in total.

　　"Facing the needs of rural agricultural development in the new era, Quanzhou has played the role of science and technology Commissioner ‘ Mechanism activity ’ , constantly explore new modes of innovative science and technology commissioners’ work, take the lead in extending the service of science and technology commissioners to secondary and tertiary industries in the province, support science and technology commissioners to participate in the construction of Xingchuang Tiandi, accelerate the transformation and industrialization of modern agricultural science and technology innovation achievements by relying on the scientific research resources and talent technology advantages of the units where science and technology commissioners are stationed, and incubate and cultivate a number of ornamental and medicinal plant industries such as Anthurium andraeanum and Cymbidium, with ‘ Gao Yan value ’ Agricultural enterprises with high added value will further promote the innovation and entrepreneurship actions of science and technology commissioners. " Li Wensheng, director of Quanzhou Science and Technology Bureau, said.

　　Build a platform and build an agricultural cooperation exhibition field between Fujian and Taiwan

　　Located in quanzhou taiwanese investment zone, Taiwan Province Agricultural Technology Exchange and Promotion Center, the first national agricultural cooperation and promotion platform between Fujian and Taiwan in China, has exchanged and cooperated with well-known agricultural universities such as Taiwan Province University, Chiayi University and Zhongxing University all the year round; Relying on the construction of Quanzhou Academy of Agricultural Sciences, it is the first to carry out the work of corporate science and technology commissioners in the province, docking high-end resources such as academician workstations, and providing "one-on-one" training and guidance services … … Entering the first batch of national stars to create heaven and earth — — Quanzhou agricultural science and technology star creates a world, and a series of "soft and hard facilities" provided for settled enterprises and makers attract attention.

　　As the earliest enterprise introduced by Xingchuang Tiandi, which specializes in producing ornamental plant Anthurium, Fengquan Agriculture is benefiting from this. "Enterprises connect with Tang Hongling and Zhang Peng through the platform, introduce famous varieties of Anthurium, innovate supporting agricultural facilities, etc., and improve the quantity and quality of finished flowers. The flowering period is extended by 10 to 15 days year-on-year, which effectively improves the competitiveness of enterprise products." Chen Yilong, head of Fengquan Agriculture, said.

　　"By building the platform of Xingchuang Tiandi, we will build a bridge between scientific and technological achievements and makers, which will not only guide innovation and entrepreneurship such as special projects, but also strengthen technical cooperation with settled enterprises, and transform while researching, greatly shortening the agricultural scientific research achievements to ‘ Field ’ Distance, promote the popularization and application of agricultural technology and excellent crop varieties. " Zhuang Weidong, director of Quanzhou Academy of Agricultural Sciences and head of Quanzhou Agricultural Science and Technology Xingcheng Tiandi, said.

　　At present, Xingchuang Tiandi provides services for the whole process of incubation, cultivation and entrepreneurship of agricultural high-tech enterprises nationwide. Under its matchmaking, Fujian Jisheng Pigeon Industry Co., Ltd., a settled enterprise, has reached a cooperation agreement with Taiwan Province Youhui Biotechnology Co., Ltd., in order to further develop the market. Over the past year or so, 15 start-ups have rushed to settle in, and there is an endless stream of incubator seekers.

　　Promote transformation and tap new kinetic energy of characteristic industries

　　Nan ‘anhui Sweet Bee Family Farm, located in Xiangyang Township, Nan ‘an City, Quanzhou, is full of numbered beehives. "You can’t take too much honey in autumn. You should leave enough rations for bees in each box to ensure the survival rate in winter." Under the careful guidance of Professor Zhou Bingfeng of Fujian Agriculture and Forestry University, director of the National Bee Industry Technology System Feeding and Machine Function Research Office of Fujian Agriculture and Rural Affairs Department, the farm has developed and bred 500 colonies of undergrowth bees, with an annual output of 25,000 kilograms of honey and an annual output of 1.5 million yuan. Under-forest beekeeping has also become a characteristic industry to drive local farmers out of poverty and become rich.

　　Previously, as a relatively poor township in Nan ‘an, Xiangyang Township had few agricultural products sales channels, low per capita income and many poor households. Zhou Bingfeng found in the field investigation that the township is surrounded by mountains and the forest coverage rate is as high as 90%, which has a unique advantage in developing bee breeding and bee culture industry. Therefore, Zhou Bingfeng teamed up with Dushan Ecological Agriculture and Forestry Cooperative in Nan ‘an City and Nan ‘an Hui Sweet Bee Family Farm to carry out Industry-University-Research cooperation, and took the lead in creating the first Xingchuang Tiandi focusing on bee entrepreneurship in Fujian — — Huitian Bee Industry has created a new world, promoted the application of new technologies such as large-scale breeding of Chinese bees and healthy and efficient breeding of Chinese bees in the national bee industry technology system, and promoted the improvement of the local Chinese bee breeding technology level and the development and growth of the bee industry.

　　While providing entrepreneurial counseling and incubation services for the bee industry, Xingchuang Tiandi also provided free bee colonies, beehives and breeding technical materials to poor households with established cards, and signed an agreement to purchase bee products, driving 51 poor households to develop bee breeding to get rid of poverty and become rich. Up to now, Huitian Bee Industry Xingchuang Tiandi has settled in 32 agricultural enterprises, successfully hatched 10 enterprises and 44 entrepreneurial teams, including 40 entrepreneurial teams from poor households. The new agricultural business entities cultivated have created economic benefits of 50 million yuan every year.

　　Excavate new kinetic energy from traditional industries and discover new possibilities from emerging industries. In Quanzhou, relying on superior resources, there are many examples of introducing special departments to take the lead in building Xingchuang Tiandi and developing rural characteristic industries. For example, Anxi Tengyun Station Xingchuang Tiandi makes full use of the radiation of Taobao Town and Taobao Village, integrates resources through Xingchuang Tiandi, optimizes the combination of scattered family-owned workshops, promotes the transformation and upgrading of traditional industries, and makes rattan and iron technology production become the leading enterprise and pillar industry in Shangqing Township.

　　Huang Zhenxia, a researcher of Quanzhou Science and Technology Bureau, said that Xingchuang Tiandi has applied modern agricultural concepts to the transformation and upgrading of the whole agricultural industry chain, focused on cultivating new agricultural business entities, supported the development of new industries, new formats and new models, and promoted the development of traditional agriculture to "internet plus" modern agriculture, circular agriculture and leisure agriculture, and has continuously become a new force to promote the transformation and upgrading of Quanzhou’s agriculture.

　　Leading the way, cultivating "new farmers" who strengthen agriculture and promote agriculture

　　"Focus on building a high-quality agricultural science and technology innovation and entrepreneurship service platform. In addition to cultivating college students’ new entrepreneurs, Zhihuigu also supports entrepreneurs such as returning migrant workers and rural youth leaders who become rich, and stimulates more enthusiasm for innovation, entrepreneurship and wealth creation of agriculture-related enterprises." You Changsheng, head of Yongchun Zhihui Valley, said.

　　According to him, at present Zhihui Valley is connected with provincial-level science delegations and associate professor Wang Mingyuan of Huaqiao University, and together with provincial, municipal and county resident cadres in Penghu Town, Yongchun, it has created a "shared poverty alleviation station" to create a shared platform for local agricultural and sideline products to integrate production and marketing, and to change "blood transfusion" poverty alleviation into "hematopoietic" poverty alleviation, helping precision poverty alleviation work.

　　Behind the vitality of Zhihui Guxing’s creation of the world, there is a strong backing, the local leading agricultural enterprise and the demonstration base of Quanzhou science and technology correspondent — — Quanzhou jinsheng ecological agriculture co., ltd. The enterprise built Quanzhou Anoectochilus roxburghii Enterprise Engineering and Technology Research Center, and innovated the techniques of sexual propagation of Anoectochilus roxburghii seedlings and imitation of wild ground cultivation under the forest. Compared with the traditional anoectochilus roxburghii produced by asexual propagation, it is more authentic and has higher nutritional value. The cultivation has driven a group of makers like Lin Zhirong to settle in Zhihui Valley Xingcheng Chuangtiandi.

　　This is another innovative measure of Quanzhou’s layout of Xingchuang Tiandi: make full use of the technical strength of science and technology commissioners, make use of the advantages of capital, manpower, technology, market and management of leading enterprises to build Xingchuang Tiandi, give play to its radiation-driven role, and build a group of "new farmers" who understand agriculture, love the countryside and love farmers, and help win the tough battle against poverty.

　　Li Wensheng said that in the next stage, Quanzhou will take Xingchuang Tiandi as an important starting point for scientific and technological work, promote the seamless connection between the system of science and technology commissioners and encouraging mass entrepreneurship and innovation, further stimulate the vitality of rural innovation and entrepreneurship, build a Xingchuang Tiandi platform suitable for Quanzhou’s development, provide rural science and technology entrepreneurship services for college students and returning migrant workers, promote the integrated development of primary and secondary industries, and drive millions of farmers to increase their income and become rich.

　　It is understood that since 2016, Quanzhou Science and Technology Bureau has gathered 392 entrepreneurial teams, 211 entrepreneurial mentors, served 370 start-ups and held 415 innovative and entrepreneurial activities by cultivating Xingchuang Tiandi. It is planned that by the end of 2020, Quanzhou will strive to cultivate 40 star-creation worlds at all levels and gather 5,000 talents of various scientific and technological innovations, and basically form an agricultural and rural innovation system with popular entrepreneurial subjects, diversified incubation objects, professional entrepreneurial services, networked organizational systems and market-oriented construction and operation.

　　CCTV News:In September this year, the Nanxian Supervision Committee of the Nanxian Discipline Inspection Committee of Yiyang City, Hunan Province received reports from many people that the commercial house they bought in Lakeview New City was charged a gas account opening fee of 2,200 yuan by the developer in violation of regulations. In fact, Hunan Province has issued regulations in early 2017, and developers are not allowed to charge users a separate gas account opening fee. Then, why will the developers of Lakeview New Town continue to charge this fee?

　　The developer of Lakeview New Town is Nanxian Huida Real Estate Development Co., Ltd. There are 6 buildings in the first phase, which have been sold out, and 5 buildings in the second phase have been capped. From December 2017 to March 2019, every time the developer sells a set of commercial housing, it will charge 2,200 yuan to the buyers separately, and a total of 2,862,200 yuan will be charged to 1,301 buyers.

　　Hu Dan, financial officer of Nanxian Huida Real Estate Development Co., Ltd.:We don’t know that this is unacceptable. We don’t know that there is a document later, that is, it should be included in the development cost, because it was not included in the development cost before, and it can be collected outside, and then we will remit it.

　　However, as early as February 2017, before the sale of real estate, the Hunan Provincial Development and Reform Commission issued the Measures for the Administration of Pipeline Gas Prices in Hunan Province, which stipulated that the installation fees of new commercial housing pipeline gas courtyard pipe network and indoor pipeline were included in the development and construction costs, and the commercial housing developers settled with the gas operating enterprises according to the regulations of the competent price department, and no longer charged separately to users.

　　Song Xianghua, member of the Standing Committee of Discipline Inspection Committee of Nanxian County, Yiyang City:According to our investigation, at least in the process of price filing, those managers should be aware of this policy, because they have already filed the relevant expenses of gas into the house price when filing; And according to our understanding, the price department also publicized this policy with them during the filing process.

　　Inadequate supervision leads to illegal charges by developers.

　　In January this year, Nanxian Real Estate Management Bureau, Development and Reform Bureau and other four departments jointly carried out special rectification of the real estate market order. However, in this inspection, the relevant departments did not carefully check and supervise the collection of water, electricity, gas and other fees for the property. After the problem was verified, the Supervision Committee of Nanxian Commission for Discipline Inspection ordered Nanxian Market Supervision Bureau to handle it according to law. At present, 1,100 buyers have received refunds, and the relevant person in charge of the price supervision department has also been dealt with.

　　During the investigation, the discipline inspection and supervision team found that during the sale of commercial housing, the developer had submitted a clearly marked book for the filing and filing of the sales price of commercial housing in Nanxian County to the relevant departments. The price list shows that the average selling price is 4,080 yuan per square meter, which includes the infrastructure for the sale of commercial housing, while the project collected and remitted by the developer does not include the gas account opening fee. However, through careful comparison, the discipline inspection and supervision team found that although the developer promised the relevant departments not to charge the gas fee, the Commercial House Sales Contract signed with the owner stipulated that the total price of the commercial house did not include the construction fee of the gas pipeline network facilities, which should be borne by the buyer.

　　Developers charge fees in violation of regulations. As the price supervision department, the original price inspection unit of Nanxian Development and Reform Bureau has been assigned to the County Market Supervision Administration, but problems have not been found in time in daily supervision.

　　Refunded 1,100 supervisors were dealt with.

　　On September 23, Nanxian Market Supervision Bureau issued a Notice of Ordering Refund to Hujing New Town developer Huida Real Estate Development Co., Ltd., ordering the company to refund the illegally charged gas account opening fee to the buyers. The reporter saw in the property office of Hujing New Town that a gas refund office has been set up here, and buyers can get a refund with their ID cards and purchase contracts.

　　Owner Cao Hui:When we took the house, the property said that the gas fee would not be available. We are in the countryside and have no pension. For us, 2200 is our living expenses for half a year.

　　In the special rectification work in January this year, the relevant personnel in charge of price supervision have been given administrative warning by the Supervision Committee of Nanxian Commission for Discipline Inspection for violating work discipline.

　　There are not many days between "stepping on the brakes" in late April and regaining the upward trend since early May.

　　On May 20th, the international gold price once again set a record high. London gold price and COMEX gold futures price both broke through the $2,440/oz mark and continued to attack. Domestic gold prices opened sharply higher, and SHFE gold in Shanghai Futures Exchange hit 582.44 yuan/gram. (Source: Wind)

　　After a break in late April, the price of gold once again opened the rising channel in May.

　　In the past two weeks, the inflation, employment, economic growth and consumption data released by the United States have weakened in an all-round way, the US dollar index and US bond interest rates have fallen back at a high level, and the market’s expected first interest rate cut has been advanced again, and macro bets have boosted the recovery of gold prices; On the weekend, the risk worries caused by the geopolitical conflict in the Middle East fermented and brought more safe-haven funds into gold.

　　Since March this year, the global gold price has ushered in a remarkable surge, and the gold price has been "soaring" all the way, and the banner of a record high has been refreshed again and again. At present, in the face of the complex intersection of short, medium and long-term influencing factors, how do you view the future trend of gold prices? Standing above the $2,400/oz mark of COMEX gold, can you still allocate gold?

　　The gold of the times

　　"Sometimes Betrayal" and "Never misjudge. "

　　How to treat the future trend of gold price? In the long history, gold has experienced many "bull and bear markets" step by step.

　　Before 1970s, the global monetary system actually took gold as the "anchor", with the US dollar pegged to gold and the major western currencies pegged to the US dollar. After the collapse of the Bretton Woods system in August 1971, it declared the end of the gold-linked era.

　　Since then, gold has experienced nine complete big markets, lasting for 32 months on average and increasing by 172% on average.

Source: Wind, open sourceresearch institute

　　The boosting factors of each gold bull market are closely related to the context of its times and are different from each other. However, no matter how the times change, most of the time it revolves around several real pricing logics closely related to the characteristics of gold itself:

　　① Financial attribute: gold does not bear interest, but it bears interest when holding US Treasury bonds. As the opportunity cost of holding gold, the real interest rate of 10Y US Treasury bonds is negatively correlated with the price of gold.

　　(2) Safe haven property: When financial, economic and geopolitical fluctuations or crises occur, the demand for safe haven of gold is often increased, which leads to a risk premium.

　　③ Currency attribute: Gold has certain substitution for the US dollar system, and the weakening of US dollar credit will benefit gold.

　　4 Commodity attributes: Gold can resist inflation, and the dollar will depreciate with inflation, so the higher the global inflation, the higher the price of gold.

　　This round of gold rising cycle began in November 2022 and has lasted for 16 months, with an increase of more than 40%. Then, from the above pricing logic, what factors have started this round of gold bull market?

　　From the traditional pricing framework, gold is a non-interest-bearing asset, and the real interest rate is the opportunity cost of holding gold. In other words, the interest rates of gold and US debt are in the same boat, and the downward interest rate will push the price of gold higher.

　　The rush of funds to the Fed’s interest rate cut expectations and the expectation of the easing cycle often become the catalyst for the rise of the gold market.

　　In the second half of last year, the Federal Reserve officially completed the current round of interest rate hikes for 11 times. After that, the US economic data slowed down in October, and the Fed’s interest rate meeting in November was biased. So far, it is the most historical interest rate hike cycle in the United States since 1980. It has basically become a consensus that when interest rate cuts become the general trend, gold will enter the rising market.

　　The trend of gold in the past 20 years can be found that the market of gold often begins with the end of interest rate hike, and finally monetary tightening or economic recovery. For example, at the end of interest rate hike in late 2006 and late 2018, the price of gold started a big rising cycle and the market went all the way to the end of the interest rate cut cycle.

　　However, in this gold bull market, we will find that the trend of gold has undergone subtle changes, and it seems that it is no longer satisfied with its limited play under the dollar order.

　　Especially since the beginning of this year, gold has become the focus not only because of its remarkable increase, but also because of its "challenge" to the traditional pricing framework: the law that the real interest rates of gold and the dollar and the United States usually change in the opposite direction has "failed".

　　Since April, the nominal interest rate of 10-year US debt has surged to nearly 4.7%, the real interest rate has risen from 1.87% to 2.41%, the US dollar index has risen from 104 to 106, but gold has soared by over 7% for a time, and it has only recently been slightly adjusted back. (Source: Wind)

　　Is there a new and more important pricing factor at work in this seemingly contradictory trend, or is it just an illusion caused by short-term emotional excitement?

　　Tracing back to the source, the bottom of the logic is the ultimate deduction of the safe-haven property of gold in the process of reshaping the global political and economic system. The occurrence of deviation and the failure of the anchor actually increase the "fragility" against the dollar.

　　Gold is a mirror image of the dollar, and the market in recent years has cast a vote of no confidence in the dollar. Although after the collapse of the Bretton Woods system, the world entered the credit currency system represented by the US dollar, and gold no longer has the functions of circulation and pricing, but it still maintains the role of value storage. Therefore, once the credit currency system represented by the US dollar is in crisis, gold will rise sharply.

　　Internally, in recent years, the US finance has continued to expand substantially, the debt scale has accumulated rapidly, and the problem of fiscal sustainability has caused social concern. Fitch downgraded the credit rating of US debt, which became the internal cause of the credit decline of the US dollar system. The rise of geopolitical risks and the rise of anti-globalization thoughts are the external causes of the decline of the credibility of the US dollar system. The freezing of foreign exchange reserves in some countries in the geopolitical conflict between Russia and Ukraine accelerated this process.

　　Internal and external factors are superimposed, the credibility of the dollar system is declining, and the world has entered the process of "dollarization". Central banks around the world have turned to gold as an anchor to stabilize foreign exchange reserves.

　　Gold sometimes seems to "betray" the traditional analytical framework, but what is never misjudged is the trend and background color. The gold of the times is generally the same.

　　The golden age

　　"Megatrend" and "Masterpiece"

　　After experiencing record highs again and again, the value of short-term transactions will decrease when standing above the threshold of COMEX gold of $2,400/ounce. A smoother rise may need to wait for catalytic factors. This is a change, but there are some unchanged ones, which ensures that the value of gold in large-scale asset allocation is still outstanding.

　　On the one hand, the "megatrend" under the current narrative background of the world remains unchanged, the US debt problem is hard to return, geopolitical events are frequent, the pattern of anti-globalization and dollarization may be further deepened, or the global central bank will continue to increase its holdings of gold, and the logic of long-term rise in gold prices is still there.

　　First, in the second half of the year, with the gradual realization of the expected interest rate cut in the United States, the downward trend of the real interest rate of the 10-year US debt is expected to support the gold price to a certain extent. However, considering that the interest rate cut is expected to rush since 2023, the persistence and elasticity of the subsequent gold market depends on the change of the expected difference.

　　Second, this year may become the biggest election year in history. In recent years, overseas risk events have continued, and the global economic policy uncertainty index center has risen, which also provides room for high gold prices.

　　Third, the game between big countries in the fields of politics, economy, industry and finance has been fully rolled out. Anti-globalization has brought about an increase in friction costs, superimposed energy transformation and inflation stickiness in the service industry, and it may be difficult for overseas long-term inflation centers to fall back quickly.

　　Fourth, on the chess game of the global economy, changes are quietly staged, the US debt problem is hard to return, geopolitical events are frequent, and the supranational sovereign credit value of gold under the new paradigm will constitute the medium and long-term investment logic.

　　Historically, the emergence of every round of gold bull market is inseparable from the strength of the gold currency attribute, which reflects the changing forces of all parties in the international monetary system.

　　According to the data released by the central bank on May 7, despite the recent rapid rise in international gold prices, the pace of the Bank of China’s increase in holdings has remained basically stable. At the end of April, China’s gold reserves were 72.8 million ounces, compared with 72.74 million ounces at the end of March. This is the people since October 2022.For the 18th consecutive month, it increased its holdings of gold reserves, setting the longest holding period.

　　Statistics show that at present, the proportion of gold in China’s international reserves is only 4.32%, which is still far below the global average of about 14%. The proportion of gold reserves in the United States, Germany, Italy and other countries in the same period is over 65%, so there is still room for improvement in the future. (Source: World Gold Council; Publicly reported)

　　From this point of view, the participants in the short-term gold game seem to face a strong opponent, which makes investors who try to play short-term gold games seem unwise and difficult to win.

　　On the other hand, after the rise, the return risk characteristics of gold itself have not changed, and the low correlation with other assets still exists, which ensures that the value of gold in the allocation of large assets is still outstanding.

　　In recent 20 years, the correlation coefficient between gold and other common large-scale assets is less than 80%, and the correlation coefficient between gold and the main indexes of A-share market is less than 50%:

　　The trend of dollar gold and Shanghai gold is highly consistent: the correlation coefficient between SHFE gold and COMEX gold is as high as 0.98 in recent 20 years. Although Shanghai gold is affected by the exchange rate of RMB against the US dollar, from the perspective of long-term allocation, the trend of the two is highly consistent;

　　The correlation between gold and A shares is low: gold and CSI 300,Most of the correlation coefficients are within 0.5, and those with equity funds and hybrid funds are within 0.7. (Source:Institute)

　　Taking the most common equal weight strategy as an example, we observe the effect of moderately increasing the gold allocation in the allocation of 28-share debt and 64-share debt respectively.

　　The calculation shows that moderately increasing gold allocation in the allocation of 28-share debt and 64-share debt can achieve a better strategy of increasing income and reducing risk at the same time.

　　In the benchmark strategy of 2:8 ratio of stocks and bonds, if 10% of funds are removed from bond assets and 5% from stock assets, the average annualized rate of return will increase by 0.69 percentage points, the maximum withdrawal will decrease by 1.97 percentage points, the annualized volatility will decrease by 0.38 percentage points, and the annualized Sharp rate will increase by 0.199.

　　On the benchmark strategy of 6:4 ratio of stocks and bonds, if 15% of funds are removed from bond assets and 5% from stock assets, the average annualized rate of return will increase by 1.11 percentage points, the maximum withdrawal will decrease by 1.57 percentage points, the annualized volatility will decrease by 0.71 percentage points, and the annualized Sharp rate will increase by 0.091. (Source: Institute)

　　On the other hand, this forever shiningNo one can predict how long its history will develop. However, the history of gold over thousands of years makes people reasonably believe that future generations will also be fascinated by gold.

　　How to allocate gold? Physical gold has always been regarded as a "safe haven", which is more suitable for investors who pursue a sense of security and long-term value storage, but it needs to be carefully stored to prevent its value from being affected by wear and tear.

　　In contrast, gold-related theme funds, such as gold stock ETF or gold ETF, provide a more convenient choice for market transactions, but when the market is hot, it is also necessary to maintain the principle of rational investment and avoid paying for high premiums.

　　However, no matter which variety you choose, you must pay attention to the position control when allocating gold. Gold is more suitable as a part of asset allocation rather than a heavy position or a single layout, and the usual position ratio is 5-10%.

　　As far as the current gold investment is concerned, perhaps the answer before investors is this:Moderately downplay the short-term trading value of gold, look for the opportunity to point gold in the shock, and explore the gold value in asset allocation from the perspective of long-term allocation.

Machine heart report

Editor: Chen Ping, Du Wei

Have you ever seen a drone that can withstand a strong gust? Researchers at the California Institute of Technology use deep neural networks to make drones no longer afraid of the wind.

When the wind is strong enough to blow out the umbrella, the drone is steady, like this:

Flying against the wind is a part of air flight. On a large scale, when pilots land their planes, the wind speed may bring them challenges. On a small scale, gusts will also affect the flight of drones.

At present, drones either fly under controlled conditions and have no wind; Or operated by humans using a remote control. Unmanned aerial vehicles are controlled by researchers to fly in formation in the open sky, but these flights are usually carried out under ideal conditions and environments.

However, in order for UAVs to perform necessary but daily tasks autonomously, such as delivering packages, UAVs must be able to adapt to wind conditions in real time.

In order to make the UAV have better maneuverability when flying in the wind, a group of engineers from California Institute of Technology developed a deep neural network Neural-Fly, an artificial intelligence tool, which can keep the UAV agile in windy conditions, and only need to update some key parameters to help the UAV cope with new and unknown wind conditions in real time.

At the beginning of the article, we have seen the wind resistance of the UAV. The following shows a quadrotor UAV. With the help of the tool developed by this research, it can complete the figure-eight shuttle operation when the wind speed reaches 27 mph:

Watch the drone flying against the wind from another angle;

In order to allow the UAV to shuttle in various wind speeds, data is essential. This research needs little data. After obtaining the flight data in just 12 minutes, the automatic quadrotor UAV equipped with Neural-Fly learned how to respond to strong winds. "The amount of data used is very small," said Michael O’Connell, a graduate student in the Department of Aeronautics and Astronautics at California Institute of Technology and one of the authors of the paper.

The study was published in the journal Science Robotics on Wednesday.

Address: https://www.science.org/doi/10.1126/scirobotics.abm6597.

ArXiv Address: https://arxiv.org/pdf/2205.06908.pdf

In the Neural-Fly experimental training, the UAV flies in the wind tunnel with six different wind speeds, the fastest of which is 13.4 mph.

Based on these data, the team created a deep neural network, and then enabled their aircraft to skillfully maneuver in the same wind tunnel, such as enlarging the gate in a figure-of-eight pattern or cruising through two oval gates. The speed of the drone in the test is faster than it encountered in the training: about 27 miles per hour. This is the maximum wind speed that the wind tunnel can produce, pointed out Shi Guanya, the author of this paper and a graduate student of California Institute of Technology. Except that only a small amount of data is needed, the software only runs on Raspberry Pi, which is a cheap computing device.

Soon-Jo Chung, a professor of aerospace, control and dynamics systems at California Institute of Technology and a correspondent, said that the error rate they saw was 2.5 to 4 times better than that of the existing SOTA technology.

The picture below shows Shi Guanya, Soon-Jo Chung and Michael O’Connell from left to right. Congratulations, Shi Guanya will join the Robotics Institute of Computer College of Carnegie Mellon University as an assistant professor in September 2023.

The researchers said that this technology will be used for drone express delivery or flying cars in the future.

Overview of Neural-Fly technology

If unmanned aerial vehicle (UAV) wants to realize continuous commercialization, it is very important to perform safe and accurate flight maneuvers in dynamic high-speed wind. However, because the relationship between different wind conditions and their influence on the maneuverability of UAV have not been deeply studied, it is challenging to design an efficient robot controller using traditional control design methods.

"Neural-Fly" proposed by researchers of California Institute of Technology is a data-driven method. As a trajectory tracking controller based on deep learning, it can learn to adapt to rapidly changing wind conditions. Figure 3(A) below shows the data collection process; 3(B) When the wind speed is 13.3km/h (3.7m/s), input and label the training data; 3(C) is the distribution of input data and label data under different wind conditions.

On-line Adaptive+Off-line Meta-learning

Figure 2 below is an overview of the Neural-Fly method, which shows that it has made progress in adaptive flight control and robot control based on deep learning. Under the dynamic wind conditions of standard UAV, Neural-Fly can track the centimeter-level position error of flexible and challenging trajectory. Specifically, this method mainly consists of two parts, namely, offline learning stage and online adaptive control stage for real-time online learning.

For the off-line learning stage, the researchers developed Domain Adversarial Invariant Meta-learning (DAML), which learned the expression of deep neural network (DNN) which is independent of wind conditions in a data-efficient way. This representation adapts to different wind conditions by updating the linear coefficients of a set of mixed depth neural network outputs.

DAIML also has data efficiency, and only 12 minutes of flight data under six different wind conditions are used to train the deep neural network. DAIML contains several key features, which can not only improve data efficiency, but also provide information by the downstream online adaptive control stage.

It is worth noting that DAIML uses spectral normalization to control the Lipschitz property of deep neural network, so as to improve the generalization ability of unknown data and provide closed-loop stability and robustness. In addition, DAIML also uses discriminant network to ensure that the learned representation is wind-invariant, and the wind-related information is only included in the linear coefficient that adapts to the online control stage.

For the on-line adaptive control stage, researchers developed a regularized compound adaptive control law, which is based on the basic understanding of how the learned representation interacts with the closed-loop control system and has strict theoretical support.

Specifically, the adaptive law uses the combination of position tracking error term and aerodynamic prediction error term to update the linear coefficient related to wind. This method effectively ensures the stability and rapid adaptation to any wind conditions and the robustness to imperfect learning. Although this adaptive control law can be used with many learned models, the accurate representation learned from DAIML is helpful to further improve the adaptive speed.

experimental result

As far as the effect of Neural-Fly is concerned, it is 66% higher than that of nonlinear tracking controller, 42% higher than that of L_1 adaptive controller and 35% higher than that of incremental nonlinear dynamic inversion (INDI) controller. All these results are achieved by using standard quadrotor UAV hardware, and the default attitude control of PX4 is running at the same time.

The tracking performance of Neural-Fly is competitive even compared with related work without external wind interference and using more complicated hardware (such as on-board optical sensor that needs 10 times control frequency and uses DC motor speed feedback).

Table 1 below shows the error tracking statistics of different methods under different wind conditions.

The researchers compared Neural-Fly with two variants, namely Neural-Fly-Transfer and Neural-Fly-Constant. Among them, NF-Transfer uses representations trained from data of different UAVs, while NF-Constant only uses adaptive control laws with trivial non-learning basis.

Neural-Fly-Transfer shows the robustness to UAV configuration changes and model mismatch. NF-Constant, L_1 and INDI methods all directly adapt to unknown dynamics without assuming the underlying physical structure, and they have similar performance.

Finally, the researcher proves that Neural-Fly can realize a series of functions, allowing the UAV to follow the trajectory and fly over the low-altitude door quickly under the condition of strong wind, as shown in Figure 1 below.

Since March, the price of gold has continued to rise, setting a new record! The domestic gold price once appeared "overnight soaring". After accumulating a large increase, recently, the international gold price fluctuated at a high level, and the gold price that had previously maintained an upward trend sat on a "roller coaster".

How to rationally allocate limited assets in the gold market and make sustained profits has become an urgent problem for investors.

The price of gold suffered a major decline after the peak.

On April 12, local time, Loco London gold rose all the way in the morning, rising nearly 2.5% in intraday trading, but then plunged sharply, which not only retreated all the gains of the day, but also finally closed with a decline of 1.25%, with a retreat of nearly 4% in the day; Futures prices also followed the spot price out of a similar market. COMEX gold futures once rose more than 3% in intraday trading and finally closed down 0.53% at $2,360.2 per ounce.

Affected by the high diving of the international gold price, the increase of Shanghai Gold also narrowed on the night of April 12, and it once rose more than 4% in intraday trading, and then it was adjusted back, and the increase fell back to 0.15% at the close.

On the evening of April 10th, the latest data of ——CPI (Consumer Price Index), the most critical inflation data before the Federal Reserve’s May resolution, was released. The US CPI rose by 3.5% year-on-year in March, which was higher than the market expectation of 3.4%. This figure intensifies the fear that inflation will accelerate again, which means that the possibility of the Fed cutting interest rates in June will decrease. The market’s expectation of the timing and frequency of the Fed’s interest rate cut this year has also changed to two times since September.

After the data was released, the international gold and silver prices fell briefly. However, the year-on-year growth rate of the US PPI (ex-factory price index of industrial producers) in March announced on the evening of 11th was slightly lower than expected, and the chain growth rate slowed down to 0.2%, which made gold and silver "rebel" again.

On April 12, COMEX gold reached a maximum of $2,448.8 per ounce; Spot gold in London once reached $2,431.78 per ounce, both hitting record highs.

The gold price of jewelry is almost equal to 730 yuan/gram.

High prices "persuade" consumers

For the recent rise in gold prices, many netizens have commented on "regret not getting on the bus" and "the price of gold jewelry is too high". Some netizens also said, "Now this price is just needed and I dare not buy it."

"This period of time is a price per day. Generally speaking, it is a small increase or a small increase." The sales of a gold shop in Chengdu told reporters, "The price of gold has really risen too high recently, and many consumers are waiting to see. I have served a couple who are about to get married before, bought a ring before the New Year, and recently wanted to buy earrings, bracelets and other accessories, just because the price of gold has risen too high recently, I have been hesitating."

The salesperson told reporters that if you are in a hurry to get married, you can consider platinum rings, and there has been no big price fluctuation recently.

The reporter visited several brand gold stores in Chengdu and found that the listing price of gold jewelry today is slightly lower than that of 730 yuan per gram a few days ago. At present, the prices of jewelry in gold jewelry stores of brands such as Lao Fengxiang, Chow Tai Fook and Zhou Shengsheng are mostly between 720 yuan and 728 yuan per gram. In the actual purchase process, different brand stores will give different degrees of concessions through in-store concessions, discounts and full reduction, and the final price will be between 680 yuan and 710 yuan per gram.

"The peak period of gold consumption is generally around the New Year. Now, after entering March and April, consumers’ purchasing enthusiasm has declined, and passenger flow and transactions will be less." A clerk in a gold jewelry store told reporters that the price of gold has been rising recently, and some "non-just-needed" consumers will also choose to wait and see.

Explore the reasons for the sudden drop in the price of gold

After analysis, the researchers studying financial issues in the Climate Change and Energy Transformation Project of Peking University Energy Research Institute believe that the main reasons for the current downward trend of gold prices are as follows:

First, the value of the dollar has risen. As a substitute for the reserve currency, gold has an inverse relationship with the value curve of the dollar. Recently, the value of the dollar has suddenly increased, and investors have chosen to buy a large amount of dollars and sell gold at the same time, and the price of gold has decreased accordingly.

Second, the interest rate is raised. Recently, former US Treasury Secretary LawrenceSummers said in an interview with relevant media that the public should accept the possibility of raising interest rates by the Federal Reserve, rather than lowering interest rates. Therefore, the increase of interest rate will make investors consider whether it is reasonable to continue to buy gold without interest, which will lead to a decline in their willingness to buy, and then affect the price of gold.

Third, the expected production capacity of gold ore has increased. According to the relevant data released recently by Canadian mining giant osino, its Gemini mine project in Namibia will provide its parent company Yintai Gold with a gold production capacity of not less than 5 tons/year after it is put into production. Yintai Gold expects that the total gold production will rise to 12 tons in 2025. At the same time, Zijin Mining also expects the gold production capacity to rise to 73.5 tons in 2024. It can be seen that the increase in gold production will lead to oversupply, which will lead to a decline in gold prices.

Experts believe that the particularity of gold itself determines that it has an extremely complex market environment. For investors, it is necessary to always remember not to blindly follow the trend, "chase up and stop falling", carefully analyze the reasons for the rise and fall of the value of the invested products, and make a reasonable investment plan according to their own wealth level. Only by doing what they can can be stable and lasting and be invincible in the market. (Wu Shihao)
