What a surprise! The China Men’s Basketball World Cup was a bargain, and the Japanese team’s host advantage was deprived.

A few days ago, the grading of the Men’s Basketball World Cup was officially released, and the World Cup draw will be made according to this grading. China team was finally assigned to the sixth gear, 32 teams were divided into eight gears according to the world ranking, and China team was also assigned to the sixth gear according to our ranking. This is also helpless. China’s current decline level is still relatively fast. According to this gear, China team will be drawn with the teams in the second, third and seventh gears respectively. In the seventh gear, because there are two Asian teams, namely Japanese team and Jordan team, it is said that China will draw one of the two teams in C? te d ‘Ivoire and Angola as an opponent of China’s group match.

Judging from the situation of such a grouping, we can basically determine the goal of China’s World Cup. It’s impossible to get into the top 16, because the teams in the second and third files are at least strong teams in Europe and America, and compared with these teams, China is not a question of winning or losing, but a question of how many points it loses. After retiring from Yao Ming, the China team has never been able to beat this level of opponents, even if it is impossible to narrow the difference to double digits with them. This can be referred to the unsuccessful match of the 2021 Tokyo Olympic Games. When the China team faced the Greek and Canadian teams, they lost more than 50 points in two games, which is a good reference.

There is only one goal left for China, that is, to become the best Asian team in the World Cup and return to the Olympic Games. First of all, the first step is to beat one of the teams in C? te d ‘Ivoire and Angola, and at the same time, we should hope that the other Asian teams, namely, the Philippine team, the Japanese team, the Lebanese team, the Jordanian team and the Iranian team, can only achieve the hope of China’s men’s basketball team returning to the Olympic Games if their records are not better than those of China.

Originally, because Japan and the Philippines are the hosts, we don’t have much hope for China to get the Olympic seats, because according to the regulations, the hosts will be assigned to the first team, so their grouping situation will be relatively favorable, or even a little lucky, and they will be able to hit the top 16 with the help of the host, just like the China team in 2019. At that time, China was put into a group with a team like Polish and Venezuelan, in fact, it was because of the glory of the host country. As a result, after the grading, we found that only the Philippines got the host qualification and advantage, and the Philippines was assigned to the first grade, while the Japanese team was assigned to the seventh grade according to its international ranking, and his grouping situation was definitely more dangerous than that of China, because he could not touch the super weak teams like Angola and C? te d ‘Ivoire. On the contrary, he had to play against the stronger teams in Europe and America such as Georgia, Latvia and Mexico, so Japan, a potential competitor, was selected.

Jordan and Lebanon are ranked eighth and seventh respectively. They are the lowest ranked and weakest teams in the same group, and it is basically impossible to win even one group match. Although Iran will meet a team with a lower ranking than itself, its strength is even worse than that of Kazakhstan after the lack of Kazakhstan season, so even if it gets a better opponent, it is basically hard to win. Therefore, China’s real potential opponent is only the host Philippines, so this grading is really a surprise to everyone. The unexpected point is that Japan, as the host, was not assigned to the first file, but was assigned to the seventh file. For China, it is a fisherman’s gain, and it is very likely that it will return to the Olympic family with the help of such an unexpected grading form.

Of course, this depends on two points. The first point is that China must win the weakest African opponent in the group stage, and also hope that the Philippines can’t play too well, because once the Philippines really rushes back to the top 16 with the help of the lottery, China can’t qualify for the Olympic Games.

The 2023 Guizhou Tongren Fanjingshan Marathon was successfully completed, and more than 5,000 people ran passionately.

From: People’s Network-Guizhou Channel

People’s Daily Online, Tongren, April 23 (Chen Jiequan) On April 22, 2023, Guizhou Tongren Fanjingshan Marathon started. More than 5,000 runners from home and abroad gathered at Fanjingshan Smart Track to run "Fanshan Water Purification" and experience national fitness.

According to reports, the theme of this event is "Fanshan Water Purification and Wisdom Leading", and two projects, full marathon and half marathon, have been set up. After fierce competition, Ethiopia’s AmanKadiBulli and HiretJemberuGirma won the men’s and women’s half marathon respectively, while domestic athletes Yin Shunjin and Zhang Ting won the men’s and women’s full marathon respectively.

It is worth mentioning that the full marathon men’s and women’s champions and the half marathon men’s and women’s champions all broke the track record of Fanjingshan Marathon.

It is understood that Fanjingshan Smart Track is the first fully enclosed track in China that can host the A2 marathon of China IAAF. It has been selected into six typical smart fitness trail projects in China, and has the timing system certified by IAAF, which can realize the track data, visualization and intelligence. In addition, the track is also equipped with intelligent facilities such as running light belt, automatic induction bathing system, intelligent AED rescue station and intelligent heart rate column, which can hold bicycle, marathon, roller skating and iron third-class competitions and national fitness events.

The starting point of the track is located in Baguanxi, Bijiang District, and the ending point is located in Lianghekou, jiangkou county. One end is connected with Fanjing Mountain, a world natural heritage, and the other end is connected with Zhongnanmen, a national night cultural tourism consumption gathering area. The total length of the track is 43.742 kilometers, passing through 24 villages and 39 bridges, stringing together the "most beautiful scenery" of Baili Jinjiang.

In recent years, relying on the unique ecological advantages and tourism resources, tongren city has vigorously developed mass sports, competitive sports and sports industry with marathon and other sports events as the carrier, and built a number of influential brand events such as Fanjing Mountain Marathon, Fanjing Mountain Mountaineering Competition, Road Cycling Race around Fanjing Mountain and China Dragon Boat Open.

How to improve the navigation accuracy of autonomous robots? Artificial intelligence: strengthen machine learning!

Robot navigation has become more and more advanced in recent years, but in very crowded environments, such as public areas or roads in urban environments, most robots still cannot navigate accurately. In order to be widely used in smart cities in the future, robots need to be able to navigate reliably and safely in these environments without colliding with humans or nearby objects.

The collision trajectory of the robot trained by standard exploration strategy (left) and the successful trajectory of the robot trained by intrinsic reward in the same scene.

Researchers from university of zaragoza and Aragon Institute of Engineering recently proposed a new method based on machine learning, which can improve robot navigation in indoor and outdoor crowded environments. This method is used inarXivAccording to a paper published in advance on the server, it is necessary to use intrinsic rewards, which are essentially "rewards" that AI agents get when they perform behaviors that are not strictly related to the tasks they try to complete.

Autonomous robot navigation is an unresolved problem, especially in unstructured and dynamic environments, robots must avoid colliding with dynamic obstacles and achieve their goals.

Facts have proved that the deep reinforcement learning algorithm has high performance in success rate and time to reach the goal, but there are still many places to be improved.

The method introduced by Martinez Baselga and his colleagues uses intrinsic rewards, aiming at increasing the motivation of agents to explore new "states" (i.e. interactions with their environment) or reducing the level of uncertainty in a given scenario, so that agents can better predict the consequences of their actions.

In their research background, researchers specially use these rewards to encourage robots to visit unknown areas in their environment and explore their environment in different ways so that they can learn to navigate more effectively over time.

Compared with the same algorithm with ICM (intrinsic reward), the training index of the most advanced algorithm.

Most deep reinforcement learning for crowd navigation focuses on improving the processing of network and robot perception.

My method studies how to explore the environment during training to improve the learning process. In training, the robot does not try random movements or optimal movements, but tries to do what it thinks it can learn more from them.

The researchers evaluated the potential of using intrinsic rewards to solve robot navigation in crowded spaces in two different ways. The first one integrates the so-called Intrinsic Curiosity Module (ICM), while the second one is based on a series of algorithms called Efficient Exploratory Random Encoder (RE3).

The researchers evaluated these models in a series of simulations, which were run on the CrowdNav simulator. They found that their two methods of integrating intrinsic rewards are superior to the most advanced navigation methods of crowded space robots developed before.

In the future, this research can encourage other robotics experts to use intrinsic rewards when training robots to improve their ability to cope with unforeseen situations and move safely in a highly dynamic environment.

In addition, the two models tested based on intrinsic rewards will soon be integrated and tested in real robots to further verify their potential.

The results show that by applying these intelligent exploration strategies, the robot can learn faster and the final learning strategy is better. And they can be applied to existing algorithms to improve them.

In the next research, it is planned to improve the deep reinforcement learning in robot navigation to make it safer and more reliable, which is very important for using it in the real world.

Returning to "Shengyutong", Shijiazhuang Kung Fu is ready to make up for the Super League.

Reporter Wang Wei reports In recent days, the Shijiazhuang Kung Fu Team, which ranked fourth in last season’s A, is conducting winter training in Guangdong. As a team that replaces the second overall position in the Super League, they are ready. Xu Mi, general manager of the club, said: "The club has submitted all the admission materials to the China Football Association and the China Football Association. The goal of the new season is to go all out to overtake and prepare for the Super League."

Shijiazhuang Kung Fu Club is an early team in winter training in 2023, in which Brazilian foreign aid defender Benicio returned to the team early to prepare for the war with the team. On February 26th, Shijiazhuang Kung Fu played a warm-up match with Hunan Xiangtao. With Zhang Hao’s double goal and Mei Jingxuan’s header, he defeated his opponent 3-0. Recently, the Kung Fu team arrived in Shunde, Guangdong Province for training and held a series of warm-up matches with local teams. On March 5, Shijiazhuang Kung Fu team and Shenzu drew 0-0, and on March 8, Shijiazhuang Kung Fu lost to Meizhou Hakka team 1-5 in Wuhua Hengbei Football Town, Meizhou. On the afternoon of March 11th, Shijiazhuang Kung Fu played a warm-up match with Guangzhou City Team in the sports center of Guangzhou University Town, and finally lost to Guangzhou City Team led by Li Weifeng 1-2.

Xu Tao, general manager of Shijiazhuang Kung Fu Club, said, "The team started its preparations earlier this year. During the whole winter training period, the team trained in the south, with the first stage in Yunnan and the second stage in Guangdong. During our training in Guangdong, we inspected the players who came for trial training. In late March, the team will go to Shanghai, Jiangsu and other places to play friendly matches with Chinese Super League and Chinese A teams, and return to Shijiazhuang in early April. "

Regarding the club’s access situation and the goal of the new season, Xu Tao said: "The club has submitted all the access materials to the China Football Association and the China Football Association. The goal of the new season is to try our best to overtake and prepare for the Super League."

From the current point of view, in the process of entering the Super League in the 2023 season, it is very likely that the Super League team will not be able to continue to fight, and Shijiazhuang Kung Fu, the fourth place in last season, actually ranks second in the Super League, which is likely to be replenished.

Zhang Hui, head coach of Shijiazhuang Kung Fu Team, said that at present, the team is built with the team of Grade A. If we go up again, we should make some efforts in foreign aid. "Our team has been emphasizing team work for so many years. During the winter training this year, everyone is fully prepared. During this time, the team played more games and was tired. After the physical reserve period, the team will improve its skills and tactics."

At present, judging from the team’s foreign aid equipment, Brazilian foreign aid defender Benicio has trained with the team early and played in the warm-up match. In addition, Shijiazhuang Kung Fu has just signed 31-year-old Ecuadorian striker Jose Ayovi, who will wear the No.33 jersey in the new season. Jose Ayovi is 1.88 meters tall and weighs 75 kilograms. He is competent as a winger and a center on the court. He has previously played in leagues in Ecuador, Mexico and Guatemala. Jose Ayovi said that he is very much looking forward to feeling the home atmosphere in Shijiazhuang and will give his best performance to the fans. It is understood that Ayovi has now joined the team, and all the team welcomed him, and he started training in the gym the day after he arrived at the team.

In the 2023 season, League A resumed the home and away game system, and Shijiazhuang Kung Fu decided to host the game in Shijiazhuang Yutong International Sports Center. At present, the China Football Association has completed the relevant inspection and acceptance work. Xu Tao said that while the team strengthens its strength through signing, it hopes to achieve the goal of surpassing success with the help of the atmosphere of "devil’s home" in Shijiazhuang Yutong International Sports Center.

"In 2009, we started from Shijiazhuang (Hebei Elite Football Club) and finally returned to Shijiazhuang after more than ten years of hard work. This year, our home will also be settled in Yutong Stadium. I hope to create a devil’s home atmosphere with Shijiazhuang fans. " Xu Tao said, "We are very excited to return to Shijiazhuang for the home game, and we are also very grateful to Shijiazhuang Municipal Government, Shijiazhuang Sports Bureau and Yutong International Sports Center for their strong support. We will go all out to play this year’s competition and hope to create a good football atmosphere with all walks of life in Shijiazhuang and contribute to local sports development and people’s lives.

Manchester United may beat Arsenal to sign a 75 million midfielder.

Arsenal’s number one target this summer is Declan Rice, but Manchester United may beat Arsenal to buy him.

As the top star of West Ham, Rice will enter the last year of his contract this summer, and he will almost certainly leave West Ham for a bigger club. It is no secret that Arsenal want to sign Rice.

It is reported that the England international, worth 75 million pounds, is Arteta’s top transfer target this summer, and the Gunners are expected to sign him. It is reported that Rice also wants to join Arsenal. According to people close to the players, before the start of next season, moving to Emirates Stadium is Rice’s "first choice". It seems that it is easy for Arsenal to buy Rice.

However, it has been reported recently that Manchester United intends to introduce Rice in consideration of the hopeless situation of buying De Rong.

It is said that although the 24-year-old wants to stay in London, Manchester United is his first choice to leave London. In addition, it is reported that the Red Devils will offer the England international a higher salary to persuade him to join.

Considering the lure of money, I feel that Manchester United can beat Arsenal in the transfer war. Arsenal may not be able to compete with Manchester United if Tenghage intervenes waving his checkbook.

Eight players in the Red Devils earn more than 200,000 pounds a week, and four players earn more than 300,000 pounds a week. On the contrary, only two Arsenal players earn more than 200,000 pounds a week. This salary expenditure can show the financial strength of Manchester United. But Rice wants to stay in London, and with the prospect of playing under Artta, Artta has taken almost every player in the team to a whole new level, which may give Arsenal an advantage.

Let’s see what Rice will choose this summer.

Digital technology in spring sowing: Beijing Jiage Tiandi launches big data platform to promote efficient spring tube

Just after the shocking solar terms, it is already a hot scene of spring sowing and spring ploughing.

This year’s No.1 Document of the Central Committee proposed to do a good job in grain production and ensure that the national grain output remained above 1.3 trillion Jin. The government work report also re-emphasized this grain production goal.

The grain output of spring sowing accounts for about 60% of the whole year, and the grain output of spring tube accounts for nearly 40% of the main rations. In order to give full play to the role of big data in helping grain production and serving spring sowing and spring management, recently, Beijing Jiage Tiandi Technology Co., Ltd. launched the "Spring sowing data management big data decision-making command platform", which provides data support for spring sowing and spring management from the perspectives of suitable areas for spring sowing, meteorological risk early warning and crop growth monitoring.

As an agricultural and rural big data application enterprise, Jiage Tiandi, based on multi-source data represented by satellite remote sensing, combined with artificial intelligence, cloud computing and other technologies, can provide big data solutions for business scenarios such as food security, rural revitalization and development, and rural homestead management. At present, it has served more than 400 million mu of cultivated land in China, and has served in nearly 30 provincial administrative regions such as Jilin, Jiangsu, Zhejiang and Guangdong, forming a unique local agricultural and rural big data application.

The "Spring Broadcasting Digital Tube Big Data Decision Command Platform" launched this time is a public welfare platform launched by Jiage Tiandi based on its own capabilities and technological advantages, which is open to the public. The platform aims to serve spring sowing with big data, and has built five functional modules, namely, spring sowing suitable area, spring sowing risk forecast, weather trend for preparation, crop growth monitoring, and spring sowing comprehensive report, which can meet the regulatory needs of crops at different stages from sowing to growth and serve local agricultural management departments.

The suitable area for spring sowing focuses on three kinds of crops: spring wheat, spring corn and early rice. Through comprehensive analysis of the data of crop phenology, temperature and precipitation, the suitable sowing range of crops in different periods can be intelligently judged. Based on the data results, relevant departments can dispatch and allocate agricultural materials in advance, so as to seize the agricultural time to carry out spring sowing.

In addition, the module also integrates the data of agricultural machinery operation, and forms a "agricultural machinery heat map" by visually presenting the agricultural machinery operation situation in the whole country, helping users to understand the farming progress in various places at the macro level.

In view of the meteorological factors closely related to crop sowing and growth, the platform analyzes and presents meteorological conditions from two dimensions: spring sowing risk prediction and meteorological trend of preparation for tillage.

The risk forecast of spring sowing focuses on several meteorological disasters such as low temperature, high temperature, drought and rainstorm, and visually shows the risk level of spring sowing in various places. When the risk is at a high level, preventive measures can be arranged in advance to avoid or reduce losses. The meteorological trend of reserve tillage reflects the data of average temperature, accumulated temperature and accumulated precipitation at present and in the same period of history, which can provide decision-making basis for agricultural operation and deployment.

In the crop growth stage, the platform introduces crop growth monitoring data with the highest accuracy of 10m, which is updated every 8 days to dynamically monitor crop growth changes, locate crop growth problem areas in time, support the efficient and accurate implementation of management and protection work, and escort the whole process of crop growth.

At present, Jiage Tiandi has opened the platform entrance in many channels, such as the official website, and launched the web and mobile terminals at the same time, providing users with convenient services, helping agricultural production in spring and contributing digital strength to ensuring food security.

Goal Net: Against Fulham, Jesus and Trossat are expected to enter the Gunners’ roster.

Live broadcast, March 12 th. Tonight, in the 27th round of Premier League, Arsenal challenged Fulham away. According to the British media "Goal Net", Jesus and Trossat are expected to enter the team’s big list tonight, and Odegard may play in this game.

This week, in the first leg of the Europa League quarter-final, the Gunners drew 2-2 away to Portuguese Sports. Jesus didn’t go out with the team, but the media reported that 25-year-old Jesus is expected to return in the league match against farmers.

Jesus’s return is a great boon for the Gunners, and Trossat is expected to return after a groin injury. Trossat suffered an injury in Arsenal’s league victory over Bournemouth last weekend, but he is likely to make the squad for the Fulham game.

Arsenal midfielder Odegard didn’t play in the Europa League match against Portuguese sports because of illness, and he may also be included in the squad for tonight’s game.

Lionel Messi is the priority transfer candidate for Miami International.

Lionel Messi remains the primary target of Jorge Mas, owner of Miami International, an American businessman who once spent time with the entourage of the OPE star.

Held talks with Miami international team.

Major leagues open to Messi.

The $2.5 billion broadcast deal offers the possibility.

What happened? Jerome Meary, a famous player’s agent, revealed that the discussion between the entourage of the Argentine superstar and Jorge Mas, the owner of Miami International, made progress during the World Cup in December. "He is the top priority of Miami International boss Jorge Mas," Miri explained. "They started talking before Messi joined Paris Saint-Germain, but the negotiations started again. Mas spent a lot of time with Messi’s representatives in Qatar."

Bigger picture: Messi’s contract will expire this summer. Although he still has incredible performance, the club that wants to sign him will inevitably be bound by financial fairness regulations. International Miami must abide by the strict salary ceiling of Major League Soccer, but it seems to have the support of the league. Commissioner Don Garber recently talked about how the alliance is going to "go outside the box" to build an agreement that may bring changes to the alliance.

The MLS broadcasting agreement of $2.5 billion may help to attract Messi, and the 2026 World Cup in the United States may also be a factor. Messi is familiar with the United States, especially Florida, where he spent his holiday and even bought an apartment in 2021.
