  The room charge of $100 for a young lady to accompany her all night is extra: most people still have the impression that Vietnam is backward and messy, and may feel that Ho Chi Minh City is terrible, but this is not the case. Except for the poor public security in the metropolis, other places in Vietnam are simple and quite safe.

  Ho Chi Minh City is an important place for foreign investment. Various traditional industries, such as textiles, shoes making, food, etc., have settled here one after another. The establishment of factories has brought a lot of job opportunities, created a prosperous scene in the daytime, and also added a lot of color to the nightlife in Ho Chi Minh City. When the night falls and the lights are on, another group of people are just about to start their day’s work.

  According to the tour leader, the daily cost of the waitress here is about 200,000 Vietnamese dong (about RMB 100 yuan), including dressing (shampoo, make-up, clothes), transportation, etc. If she is not arrived by the guests today, she will lose money.

  Moreover, just accompanying wine can only maintain a normal life, losing the meaning of going to sea. For them, spending the night with guests is really profitable, but according to the rules, it is necessary to tap Mommy. Whether they are greedy for glory or forced, only in this way can they meet their economic needs.

The football boy was rescued from a cave in Thailand and died on a British campus. The cause of death was announced.

The Beijing News (Reporter Xu Bangyin) Recently, according to foreign media reports, the forensic doctor in Leicestershire, England, announced the cause of death of Dom, the captain of Thailand’s "Cave Football Team". In February this year, the 17-year-old Thai football boy who studied in the UK died unfortunately. Today, the forensic doctor confirmed that Dom committed suicide.

Dom is the captain of Thailand’s "Wild Boar" football team. He was trapped in a cave in Thailand with his teammates and miraculously rescued after 18 days. On June 23, 2018, due to a sudden rainstorm, 12 players and 1 coach of the "Wild Boar" football team were trapped in a cave in Chiang Rai province, Thailand, and thousands of rescuers from all over the world were involved in search and rescue work. On July 10th of that year, Dom and 11 teammates and coaches were all rescued.

According to foreign media reports, when the search and rescue work went on the ninth day, divers found the trapped people of the "Wild Boar" football team. Dom, who was only 13 years old at that time, was the first to deliver the news to the outside world on behalf of the team.

It is widely known that the Thai football teenager was rescued after being trapped in a cave for 18 days. Twelve players were invited to Britain to watch the Premier League match. For children who have experienced the test of life and death, their life trajectory has changed. A teammate once said that Dom’s goal is to become a member of the Thai football team.

In 2022, Dom got a scholarship from a foundation in Thailand and got the opportunity to study in the UK. Last August, Dom went to Brookhouse College, a boarding school with a professional football college in Leicestershire, England, where Dom could continue his professional football training.

In February this year, an accident happened. Dom, who was in a coma in the dormitory, was found by his roommate and was rushed to the local hospital. After two days of rescue, Dom died unfortunately. After a preliminary investigation, Leicestershire police said that there were no suspicious signs of Dom’s death, but the specific cause of Dom’s death was not announced.

After more than half a year’s in-depth investigation, Catherine Mei Sen, a senior forensic doctor in Leicestershire, recently concluded that Dom committed suicide. Catherine Mei Sen said that the police found no evidence to prove that Dom’s death had third-party involvement or other suspicious circumstances. "Dom didn’t know much about the mental health service department before his death, and he didn’t know why he made such a choice."

Dom experienced a moment of life and death in 2018. Whether he was trapped in a cave or was taken out of the cave by rescuers in a coma, the situation was extremely dangerous. But when Dom’s life was back on track and there was a smooth road ahead, he chose to take his own life. Iain smith, president of Brookhouse College, issued a statement saying that all people are still immersed in grief over Dom’s death and will always miss Dom.

New energy vehicles lead the way, develop with high quality and move towards a powerful automobile country.

Source: China Economic Net

China’s new energy vehicles have entered a new stage of large-scale, global and high-quality development, and the system strength is constantly maturing and the market position is continuously consolidated; More importantly, a number of highly competitive automobile brands in China have emerged. However, opportunities often coexist with challenges, and China’s new energy vehicles still have shortcomings in some key areas, which need to be overcome.

After 70 years of development, China automobile industry has entered a new stage of high-quality development. Since the beginning of this year, driven by the policy and market, China’s automobile production and sales have steadily increased, constantly hitting record highs, which has played an important role in promoting consumption and boosting economic development. Among them, new energy, automobile export and high-end car market have all become important forces to promote the development of the automobile market. To this end, China Economic Net auto channel will review and summarize these three aspects in order to help the industry further achieve high-quality development. Today, "New Energy Vehicles Leading the Way, High-quality Development Towards Automobile Power" was launched.

Developing new energy vehicles is the only way for China to move from a big automobile country to a strong automobile country. In recent years, driven by policy and market, China’s new energy automobile industry has achieved leap-forward development, and its production and sales have ranked first in the world for eight consecutive years.

According to the data of China Association of Automobile Manufacturers (hereinafter referred to as China Automobile Association), from January to October this year, the production and sales of new energy vehicles in China were 7.352 million and 7.28 million respectively, up by 33.9% and 37.8% respectively, and the market share reached 30.4%. In October, the production and sales were close to one million vehicles. In July this year, the 20 millionth new energy vehicle rolled off the assembly line, which marked that China’s new energy vehicle industry entered a new stage of large-scale and global high-quality development.

The China Automobile Association predicts that the production and sales of new energy vehicles will reach 9 million this year. At present, the cumulative sales volume of new energy vehicles in the first 10 months has exceeded that of last year. The China Automobile Association said that according to the current data, the production and sales targets of new energy vehicles can basically be achieved this year.

Policy escort, high-quality development of new energy vehicles

The scale of new energy vehicles in China continues to rise, which is inseparable from the "escort" of policies. Fang Haifeng, chief expert of China Automotive Technology and Research Center Co., Ltd. and deputy director of China Automotive Strategy and Policy Research Center, said, "From a policy perspective, the relevant state authorities have increased policy support during the market introduction period to promote the industrialization of new energy vehicles, adhered to diversified development, and introduced a series of policy measures, creating a good policy environment for the development of the whole industry and building a policy support system."

Since the beginning of this year, the national ministries and commissions have intensively introduced policies related to new energy vehicles, from the continuation of the vehicle purchase tax reduction policy for new energy vehicles to the end of 2027, to the launch of the "thousand counties and thousands of towns" new energy vehicle consumption season, to the promotion of the construction of charging infrastructure system, and to strengthen the safety management of new energy vehicles, improve the motor vehicle scrapping and renewal policy and the promotion mechanism of new energy vehicles, covering the whole life cycle of new energy vehicles from production, purchase, use to recycling.

This also makes the strength of China’s new energy automobile industry system mature, and its core position in the global new energy automobile industry becomes more and more stable. From the perspective of industrial layout, with the "Three Electricity" (battery, motor and electronic control) becoming the core components of new energy auto time, China has formed a competitive advantage in relevant industrial chains, and outstanding suppliers such as Contemporary Amperex Technology Co., Limited, Horizon and Hesai Technology have emerged. Zhang Yongwei, vice chairman and secretary general of China Electric Vehicle committee of 100, also said, "At present, China has formed a relatively complete electrification supply chain, which occupies an important position in the world. At this stage, about 70% of the global battery production capacity is in China. In the future, China is likely to become a global automotive supply chain center. "

In the technical field, ultra-fast rechargeable batteries make new energy vehicles comparable to fuel vehicles, the meta-universe is changing the in-vehicle experience, large models promote the rapid growth of autonomous driving ability, and even before flying cars take the stage … Many innovative technologies are gathering in the new energy field. According to Tao Qing, spokesperson of the Ministry of Industry and Information Technology, in the first three quarters of this year, China’s new energy automobile industry showed the characteristics of rapid improvement in technical level. The energy density of mass-produced power batteries reached 300 WHr/kg, the average driving range of pure electric passenger cars exceeded 460 kilometers, and the proportion of vehicles with L2 or above self-driving function in passenger cars exceeded 40%.

At the product level, it has become a new energy market of "fairy fights". In 2023, a large number of new China brand members will be added, covering all market segments. Geely Panda mini, Wuling Binguo, BYD Seagull, Baojun Yueye, Jianghuai Yttrium 3, Nezha AYA and Baojun Yunduo in the small car market; Extreme Krypton X, Haval Xiaolong, Geely Yinhe L7, Geely Yinhe L6, Beiqi Polar Fox Koala, Nezha X and Changan Qiyuan A05 in compact market; Deep blue S7, Tucki G6, Tengshi N7, Zhiji LS6, Qichen VX6 and Haoplatinum GT in the medium-sized car market; Zhiji LS7, Weipai Lanshan, Tanks 500 Hi4-T, Gaohe HiPhi Y, Tengshi N8, Feifan F7, Lantu Zhuiguang, Changan Qiyuan A07 in medium and large markets; Chuanqi E9, Hechuang V09 and Weipai Gaoshan DHT-PHEV in MPV market; And look up to U8 and Haoplatinum SSR…… … More than that, there are more generations, changes and new models to join, and China brand new energy vehicles are welcoming the era of a hundred flowers.

In terms of infrastructure construction, the data released by the National Energy Administration shows that China’s charging infrastructure has increased from hundreds of thousands in the early 13 th Five-Year Plan to 6.928 million by the end of July 2023, an increase of over 60 times; From January to July, the charging capacity of new energy vehicles nationwide reached 44.14 billion kWh, up 99.6% year-on-year, which has exceeded the charging capacity of last year. At the same time, nearly 90% of expressway service areas in China have been equipped with charging facilities. As a result, China has formed a charging infrastructure system with the largest number, the widest service range and the most complete variety in the world.

Li Shaohua, deputy secretary-general of China Automobile Industry Association, confidently said, "After years of development, China’s charging infrastructure industry has established a relatively complete technical standard system, charging facility quality system, charging operation management system, etc., and summarized and formed a series of achievements and experiences."

Opportunities and challenges coexist, and China brands accelerate their upward breakthrough.

With strong policy boost, strong market demand and perfect industrial guarantee, the accelerated development of China’s new energy automobile industry comes naturally. More importantly, new energy vehicles are the best carrier for China’s automobiles to break through and expand outward.

Specifically, in the new energy era, a number of highly competitive automobile brands have emerged in China. In October this year, BYD’s sales exceeded 300,000 vehicles for the first time, which further consolidated the local advantages of China brand. In addition, data released by the Ministry of Industry and Information Technology show that in the first three quarters, the domestic market sales of China brand new energy passenger cars accounted for 80.2%. Among the new brands, LI sold more than 40,000 vehicles in October, and it has got rid of the traditional multinational giants in the luxury SUV market.

Looking around the world, China’s new energy vehicles have also become a beautiful landscape. According to the data of China Automobile Association, from January to October, domestic new energy vehicles exported a total of 995,000 vehicles, a year-on-year increase of 99.1%. More than that, China’s new energy vehicles have also moved to the developed markets in Europe and America. For example, SAIC MG brand sold more than 200,000 vehicles in the European market in the first 10 months, and MG4 EV won the sales champion of European pure electric compact models.

In addition, China’s new energy vehicles are characterized by technological globalization. In July this year, Volkswagen brand and Xpeng Motors reached a technical cooperation framework agreement to jointly develop two Volkswagen brand electric vehicles; Audi also signed a strategic memorandum with SAIC, which will rapidly and efficiently expand the high-end market intelligent networked electric vehicle product portfolio through joint development.

At the same time, however, China’s new energy vehicles are still facing challenges, and their shortcomings need to be overcome urgently.

First of all, there is still unbalanced development in the new energy vehicle market in China. Xin Guobin, vice minister of the Ministry of Industry and Information Technology, said, "From the perspective of urban and rural markets, the rural market has not been fully tapped." The data shows that in 2022, the sales of new energy vehicles in rural areas of China only accounted for 4% of the total sales of vehicles in rural areas, far below the overall level of 25.6% in the industry. According to the Study on Electric Vehicle Travel in Rural Areas of China published by China Electric Vehicle committee of 100, in March this year, the penetration rate of pure electric passenger cars in counties and townships was 16%, and that of hybrid passenger cars was 8%, both of which were far below the level of first-and second-tier cities.

The rural new energy vehicle market is still a blue ocean. According to the relevant research of China Automobile Strategy and Policy Research Center of China Automobile Center, every promotion of a new energy vehicle will drive the value-added of the upstream and downstream industrial chains of automobiles by 2.5 to 3 times. Therefore, supporting new energy vehicles to the countryside will play a vital role in promoting new energy vehicles in China and even the overall economic development.

Furthermore, China’s new energy vehicles still have shortcomings in some key areas. Wan Gang, chairman of China Association for Science and Technology, once bluntly said that there are still some problems in the development of new energy automobile industry, such as high price of basic resources, poor supply chain and some technical constraints. Fu Bingfeng, executive vice president and secretary general of China Automobile Industry Association, also believes that the shortcomings of China’s new energy automobile industry in the fields of chips, basic software and key materials need continuous efforts to make up.

Song Kai visited Qatar, and the China Football Association restarted "football diplomacy"

Reporter Jin Cuo reports On October 31st, local time, Song Kai, the new president of China Football Association, appeared at the AFC Annual Awards Ceremony, which was his first visit since he took office. Song Kai’s move hoped to restart China’s football diplomacy and open up the situation.

In January this year, Du Zhaocai, then vice-chairman and secretary of the Party Committee of the Football Association, was elected as a director of FIFA, with 18 votes at the bottom, and was unable to be re-elected. Due to the special regulations of the AFC (only one election was allowed), China Football was "aphasia" in the executive committee of the highest institution of the AFC for the first time.

Subsequently, the chairmen and vice-chairmen of the 16 committees under the AFC were adjusted, and no one in the China Football Association was elected.

However, according to the current "status" of China football, whether it is elected as a director or not has little influence, because even when Zhang Jian and Du Zhaocai were directors, it didn’t bring much help to China football. Even when Du Zhaocai was the chairman of the arbitration committee, China football didn’t even benefit from it, and even suffered a lot when facing the West Asian teams.

In fact, after Zhang Jilong, China’s football diplomacy or "foreign affairs" has been "aphasia". Since then, neither Zhang Jian nor Du Zhaocai has done it, especially Du Zhaocai.

That is to say, after Zhang Jilong’s retirement, China’s football diplomacy has been broken, and the "advantages" of Chen Chengda, Xu Fang and Zhang Jilong, which come down in one continuous strain, are gone.

For Song Kai, there are many things to do after taking over the mess of China Football Association. Youth training and league matches are very important. Judging from his trip to Doha, football diplomacy has not been neglected, or an open attitude.

In the past, some leaders of the Football Association actually did not attach importance to football diplomacy, and some were jealous and some were disdainful of Zhang Jilong’s contribution. Despite Zhang Jilong’s persuasion, Nan Yong "formed an alliance" with Haman, then president of the Asian Football Association, and got a temporary "pleasure" for a football player in China. At that time, he was full of pride. "What football diplomacy is, it’s just interests."

Nan Yong’s words have some truth. "Interests" are indeed fundamental, but connections are also indispensable. Otherwise, there is no channel for "mutual benefit", or why do people believe you? Haman took over at that time, mainly because he was under siege and needed an "exit".

At present, the situation in the AFC is that "the west wind overwhelms the east wind", and for many years, it is very difficult for China football to regain its voice, which Song Kai should be aware of.

In 2013, with the support of Blatter, Salman ascended the presidency of the AFC, and was re-elected for three times since then. The latest term is in 2027. From the current point of view, he has completely controlled the AFC, with no opponents, and his power is better than that of Haman. His secretariat manages almost everything.

Over the years, China’s football diplomacy has been guided by the principle of "following the establishment", which has both advantages and disadvantages. The advantage is that you can sometimes have a sip of soup, but the disadvantage is that you can only have soup.

Previously, China football could not speak because it could not bring "benefits". At that time, many sponsors of the AFC were Japanese and Korean companies, while there were almost no in China; Later, China enterprises participated extensively, but did not express their due "interest demands". They only paid money and did nothing.

For China football, a good opportunity is that an enterprise in China won the business development right of AFC for 8 years (from 2021 to 2028) for 2.4 billion US dollars in 2018. Unfortunately, due to the epidemic, the company lost money for years and was unable to pay the relevant funds, so it had to re-sign the contract and give up most of the benefits. Among them, AFC suffered heavy losses, and China football was also negatively affected.

Since then, China Football Association gave up the right to host the Asian Cup, which also caused dissatisfaction with the Asian Football Association. Among them, Du Zhaocai’s "inaction" was involved.

Therefore, in a certain period of time in the future, China football must regain its "trust" and establish new "contacts" with the world football. Song Kai revealed that the China Football Association is discussing matters related to hosting the World Youth Championship and the World Youth Championship.

In addition, China enterprises that sponsor FIFA and AFC must form a joint force and work closely with the Football Association to maximize the interests of all parties.

During his stay in Doha, Song Kai first met with AFC President Salman and talked with some AFC leaders. Accompanied by Song Kai, Luo Zhao, who has worked in the Foreign Affairs Department of the Football Association for many years, is very familiar with many things about the AFC.

Later on October 30th, local time, Song Kai met Salman on the day he arrived in Doha. Salman congratulated Song Kai on his election as president of China Football Association and reiterated that AFC will continue to cooperate with China Football Association. "I believe that under the leadership of Mr. Song Kai, China football will be promoted to a higher level." Salman said that he was concerned about Song Kai’s remarks. "We have seen the determination of the leadership of the new China Football Association." Song Kai expressed his appreciation and welcome for Salman’s commitment. Salman revealed that the AFC will have a series of concrete development plans to help China’s football continue to develop.

On the 31st, on the day of the AFC Awards Ceremony, Song Kai also had a talk with relevant people of AFC. Although he didn’t have a thorough understanding, he at least laid a foundation. In fact, Zhang Jilong once said that China’s football diplomacy is nothing more than four words: making friends.

Of course, it is whimsical to expect Song Kai to restart football diplomacy at once and even achieve results. After all, he is only a "newcomer", but at least, he has taken the first step. In the future, under the guidance of the policy of "making friends", he will be down-to-earth and may recover lost ground.

Summary of European football: Bayern Paris won the championship, Inter Milan locked in the Champions League qualification, and Rome missed the top four.

On May 28th, Beijing time, let’s take a look at the latest situation of the five major leagues in Europe.

Grand Paris won the championship one round ahead of schedule.

In the 37th round of Ligue 1, Lionel Messi scored 496 goals in the history of the five major leagues, helping Paris draw 1-1 away from Strasbourg. With only one round left, Barley was 4 points ahead of Lance, the second in the league, and won the championship ahead of schedule.

In the past six years, Barley won five French champions, and in the past 11 years, he won nine French champions. Messi joined Paris for two years and also won two French champions and a French Super Cup.

The script of the Bundesliga title competition

In the last round, Dortmund surpassed Bayern by 2 points. In the final battle of the Bundesliga, Dortmund can break Bayern’s monopoly on the Bundesliga champion in the past 10 years by defeating Mainz, who lost four games in a row at home.

As a result, Dortmund was beaten 2-0 by Mainz as soon as he came up. Although he pulled two goals in the end, he still only got a 2-2 draw. In this game, Alai was the most unlucky one. He missed a penalty in the first half, scored a goal in stoppage time in the second half and was blown off because of offside. After the game, his INS was captured by extreme fans.

Bayern took a 1-0 lead early, and was equalized 1-1 by Cologne in the second half because of Gnabry’s handball. If Bayern can’t score all 3 points, Dortmund will win the championship. However, Mucia La, who came off the bench, scored the winner in the 89th minute, which ruined Dortmund’s last hope of winning the championship. In the end, Bayern beat Cologne 2-1 and beat Dortmund to win the championship because of the goal difference advantage.

Inter Milan lock in the top four in Serie A.

In the 37th round of Serie A, lautaro scored a goal and Lu Kaku scored a goal. Inter Milan beat Atalanta 3-2 at home, locked the top four in Serie A one round ahead of schedule, and got a Champions League seat.

Roma missed the top four in Serie A.

In the 37th round of Serie A, it was difficult for chaaraoui to save the goal. Rome lost two goals in three minutes in the final stage, and was finally reversed by Florence 2-1, which made it unbeaten in seven rounds of the League. Now, with only one round left, they are four points behind AC Milan, the fourth in the league, and they are determined to miss the top four in Serie A one round ahead of schedule. They want to qualify for the Champions League next season, and only the Europa League is left.

Luton succeeded in overtaking.

Luton beat Coventry 7-6 on penalties in the final of the Championship promotion play-off, and the team history was promoted to the Premier League for the first time. According to Luton’s official introduction, they are the first team to enter the Premier League from a non-league, and they were still in the fifth league nine years ago. At present, three newly promoted Premier League horses have been identified, namely Burnley, Sheffield United and Luton.

Three-dimensional visualization technology of power transmission lines, intelligent management of power supply chain

Content: Power transmission line is an important part of power system, and the management and maintenance of the line is the key to keep the power supply chain smooth. How to manage power transmission lines efficiently and predict the potential problems of lines in advance is the core issue of intelligent and digital transformation in the field of power supply. Three-dimensional visualization technology can visually display power transmission lines, and realize real-time monitoring and operation and maintenance management of lines based on data model, which is convenient for power managers to finely manage line status. # Three-dimensional visualization of power transmission lines #

Three-dimensional visualization technology can establish three-dimensional cultural design based on power transmission lines and realize comprehensive monitoring and management of lines. Through three-dimensional digital modeling, the lines can be visually displayed and the information can be visually expressed. In addition, with the help of artificial intelligence, big data and other technologies, all data in the power supply chain can be intelligently analyzed and processed. Power managers can analyze these data, predict the operation status of the line and maintain it in time.

Especially in the event of catastrophic events in power supply chain, power managers can more accurately and quickly grasp the line fault situation, quickly carry out spread control and fault repair, reduce the line maintenance cost and improve the stability of power supply. Large-screen visual decision-making system, the digital age has come.

The application of 3D visualization technology is bringing new opportunities and challenges for intelligent management and digital upgrade of power transmission lines. In the future, the development of three-dimensional visualization technology of power transmission lines will become more and more intelligent, convenient and efficient, helping power managers to better fundamentally solve the difficult problems in power supply chain.

Improvement of lung cancer staging by PET AI model

A research team in Germany said that an artificial intelligence (AI) model based on routine data of F-18 FDG-PET/CT scanning can improve the accuracy of staging treatment for patients with metastatic lung cancer.

A research team led by Dr Julian Rogasch of Charette Medical University in Berlin has developed a machine learning tool to help evaluate mediastinal lymph node metastasis in patients with non-small cell lung cancer (NSCLC). They found that the model was more accurate than the visual score of PET, and suggested that it could help doctors make more accurate treatment plans. Their results were published in the February 23 issue of the European Journal of Nuclear Medicine and Molecular Imaging, and they wrote that the model can be used as a network application to further promote verification.

Dr. Rogasch and his colleagues wrote: "This model was developed for routine clinical care, and the probability of N2/3 disease (that is, whether there is N1, N2 or N3, which is the key to determine stage II and III diseases) was estimated according to the results of F-18 FDG-PET/CT. This is based on routinely available variables, most of which are already part of the F-18 FDG-PET/CT report in routine clinical nursing. "

In patients with non-small cell lung cancer, accurate imaging of thoracic lymph node metastasis is very important for treatment planning. The authors explain that patients with N0/1 disease usually need surgery, while patients with more extensive N2/3 disease need multimodal treatment. They pointed out that although F-18 FDG-PET/CT is the most effective method, it may be limited by false positive results, and invasive biopsy is often needed to confirm suspicious cases.

In order to evaluate the value of AI model designed to assist these cases, the researchers collected data of 491 patients with non-small cell lung cancer, who were imaged before treatment with analog PET/CT scanner or digital PET scanner. According to the scanner used, patients were divided into training queue and verification queue. There were 385 people in the simulation training and testing queue and 106 people in the digital verification queue.

Forty clinical variables, tumor features and image variables, such as F-18 FDG radioactive tracer uptake (SUVmax) of lymph nodes, were collected, and different combinations of variables in several machine learning methods were compared. The researchers chose a gradient enhancement classifier with 10 eigenvalues as the final model.

The above picture comes from a 54-year-old woman in a training and testing cohort, suffering from G2 adenocarcinoma in the right upper lobe (44 mm). The uptake of F-18 FDG in several hilar and mediastinal lymph nodes was higher than that in normal liver (PET score was 3). The blue arrow shows N2 paratracheal lymph nodes with a short axis of 7 mm and an SUVmax of 3.5. According to the visual assessment, this case is suspected of N2 disease. According to the gradient enhanced classifier model, the probability of N2/3 is only 0.17. Ultrasound-guided bronchial puncture biopsy of LNs at the same hilum, paratrachea and carina confirmed that the patient was NO.

The gradient-enhanced classifier model shows that the AUC in the training and testing queue is significantly higher than the visual PET score (0.91 vs.0.87, p=0.003), and the AUC in the verification queue is slightly higher (0.94 vs.0.91, p=0.023).

It is worth noting that the gradient-enhanced classifier model is superior to the visual evaluation of radioactive tracer uptake in lymph nodes above mediastinum, which is the most common and effective diagnostic threshold in visual F-18 FDG-PET/CT evaluation. They also reported that the coordination of PET images between the two scanners does affect the visual evaluation of SUVmax and lymph nodes, but it does not reduce the AUC of the model.

In order to facilitate further verification, the team has published all variables and machine learning codes as open data and used a web application on GitHub. The network application requires users to input 10 eigenvalues to calculate the prediction probability of N2/3 disease.

Dr. Rogasch and his colleagues said that the research results show a good prospect and deserve further study.

They concluded: "We look forward to the external verification and validity proof in the intervention test."
