An Air Force aviation unit in northwestern China, the first to use the PLA's most advanced fighter jet, the J-20, has recently been performing joint tactical exercises with J-16 and J-10C aircraft, according to the Air Force. In the exercises, the radar-evading J-20s take advantage of their situational awareness and stealth abilities to seize air superiority. Then J-16s and J-10Cs launch long-range precision strikes against land targets. The J-20 has displayed not only overwhelming air combat superiority in the drills, but also a crucial ability to clear the path for and coordinate combat with other types of fighter jets, the Air Force said in a statement. It added that many pilots in the unit are able to fly all of the three top planes. He Xing, a pilot taking part in the drills, was quoted by the statement as saying that the unit's pilots are trained to operate J-20, J-16 and J-10C to familiarize themselves with the aircraft and get to know their strengths and weaknesses. Then we will be able to know how to use the advantages of a certain type of plane to complement other models and how to make the best use of each aircraft, he said. Yang Wei, chief designer of the J-20 at Aviation Industry Corp of China, said in a China Central Television program about the exercises that the J-20 was designed to carry out strike operations to help obtain air combat superiority. The J-20, the first of China's fifth-generation combat aircraft, made its maiden flight in January 2011 and was declassified in November 2016. It started to be commissioned to the Air Force in 2017, becoming the third stealth fighter jet to enter service, after the United States' F-22 Raptor and F-35 Lightning II. It has been sent to take part in a series of combat exercises and has practiced beyond-visual-range aerial fighting maneuvers during the drills, according to the Air Force. The jet bears the important responsibility of clearing a path for other aircraft in an air battle, according to Zhang Hao, head of an Air Force flight-testing center that has deployed the jet. The J-16 and J-10C are also among China's latest combat aircraft and were developed by Chinese designers. They were delivered to the Air Force around 2017, according to the Air Force. custom fidgetwristbandcustom made rubber braceletsyouth wristbandssilicone rubber bands
National association sees great potential for improved servicesA national association was set up on Saturday to promote the integration of artificial intelligence technology with medical care to improve services.The Chinese Intelligent Medicine Association will provide a platform for research, exchange and cooperation in intelligent medicine, Zhang Yanling, president of Chinese Medical Doctor Association, which supervises the new association, said at its inauguration ceremony on Saturday.While promoting the use of AI in medicine, the association will also assist the government in formulating standards and regulations for the development of intelligent medicine, which is still at its infancy, he said.Intelligent medicine will profoundly transform the medical care sector, and may bring great benefits to both patients and doctors, Zhang said, adding that 124 hospitals have practiced intelligent medicine in China."Intelligent medicine involves utilization of the latest technologies, including the internet, big data and artificial intelligence," said Dong Jiahong, president of the new association. "Developing intelligent medicine is of great importance in achieving more balanced distribution of healthcare resources, improving quality of medical care, efficiency and lower cost."Chen Xiaoming, president of First Affiliated Hospital of Wenzhou Medical University, in Wenzhou, Zhejiang province, said a big challenge in developing intelligent medicine in China is a serious shortage of talented people who excel in both medicine and information technology."Universities should strengthen education and production of people who excel in both medicine and AI," he said. "Doctors and IT researchers at enterprises should work together to breed such talent."Lin Haotian, a professor in the Zhongshan Ophthalmic Center at Sun Yat-sen University, said doctors should play a more important role in developing intelligent medicine because they work for patients and know their needs best."But doctors at big hospitals are usually too busy, and cannot find enough time for research," he said. "They need more support from the hospitals."As with many other sectors, the latest big data and AI technologies are increasingly being integrated with the health sector.The ophthalmic center in Guangzhou, Guangdong province, for example, opened the first AI clinic in China last year to diagnose cataracts with the help of an AI-assisted platform.In a clinic at the center, images of patients' eyes are uploaded to the platform, and a diagnosis can be given within minutes. Treatment plans are also offered for doctors' reference. The accuracy of the AI diagnoses exceeds 90 percent, the hospital said.Watson for Oncology, a cognitive computing platform designed by US company IBM can provide treatment options to commonly seen cancers. It has been used at 65 big hospitals in 39 cities in China, according to Fu Gang, chairman of Baheal Pharm, which introduced the system to the country last year.The system is expected to be used at more grassroots hospitals to help improve cancer diagnoses, he said.In a guideline released by the central government late last month that aims to promote the development of "Internet Plus healthcare", some major areas of focus were highlighted, including promoting the integration of internet technologies in medical care, public health, medicine teaching and medicine supply.Accelerating development of the "Internet Plus healthcare" platform is expected to bring more benefits to patients, including extending the coverage of high quality healthcare services, which is now highly concentrated in big cities, to more people, according to the guideline.
