  UN High Commissioner for Refugees Filippo Grandi on Thursday expressed concern over the planned changes to the asylum system in the United States."We are worried that the proposed Procedures for Asylum and Withholding of Removal, Credible Fear and Reasonable Fear Review, currently being circulated for public comment, mark a departure from humanitarian policies and practices long championed by the United States and rooted in international law," Grandi said in a statement.The statement said that the changes contained in the pending regulation, combined with separate restrictions enacted in recent years, would mean that many people fleeing persecution would be unable to request, or obtain, protection in the United States."The obligation to provide a safe haven to those fleeing armed conflict, violence or persecution reflects fundamental values rooted in many legal traditions, and is a core aspect of modern international law," it said."We have urged our interlocutors in the government of the United States -- and in all governments around the world -- to keep this in mind as they decide what policy decisions are appropriate," said the statement.UN High Commissioner for Refugees Filippo Grandi on Thursday expressed concern over the planned changes to the asylum system in the United States."We are worried that the proposed Procedures for Asylum and Withholding of Removal, Credible Fear and Reasonable Fear Review, currently being circulated for public comment, mark a departure from humanitarian policies and practices long championed by the

Using artificial intelligence (AI) technologies, an international research team led by Chinese scientists has developed a rapid and accurate screening model to detect lymph nodes, which can assist doctors in cancer treatment.Lymph nodes are the human immune system's first line of defense, protecting people from illnesses and virus infections. In the human body, lymph nodes are hundreds of small, round or bean-shaped glands that gather in the neck, armpit, abdomen and groin.Cancer that starts in another part of the body and spreads to the lymph nodes is called metastasis, which is important for clinicians to judge the development of cancer.However, the current MRI screening methods are time-consuming and can not identify all the lymph nodes in the scan regions, lowering the detection accuracy.A single lymph node occupies less than one-thousandth of an MRI sample, and it is easily confused with blood vessels and other tissues, said lead researcher Gao Xin, of the Suzhou Institute of Biomedical Engineering and Technology under the Chinese Academy of Sciences."Even an experienced radiologist has to spend three to 10 minutes examining lymph nodes on one sample, and each case needs approximately 20 samples.""For small lymph nodes with a diameter of less than 5 mm, the detection accuracy is always less than 70 percent," Gao added.Based on MRI image data selected from 293 patients with rectal cancer at the Sixth Affiliated Hospital of Sun Yat-Sen University from 2013 to 2016, researchers developed the AI-assisted screening model. This turned detection experiences, accumulated by experts, into algorithms. The AI can detect the lymph nodes by a higher percentage, with only 1.37 seconds on each sample. This is 100 times faster than human detection.The researchers tested the AI model in patients at four medical centers in Guangzhou, Beijing, Suzhou and Guizhou, and compared its results with those of four Chinese radiologists, specializing in gastrointestinal diseases. The results showed that it can accurately identify 3-mm-diameter lymph nodes with a detection accuracy of 80 percent.The results were recently published in the journal EBioMedicine under The Lancet. Researchers from the University of Wisconsin School of Medicine and Public Health also participated in the study.The AI model can also be used to detect metastatic cancers in other human organs or tissue, according to Gao."We believe the AI-assisted screening model can save a great deal of manual labor and improve clinical efficiency, which will benefit more patients," said Gao.Using artificial intelligence (AI) technologies, an international research team led by Chinese scientists has developed a rapid and accurate screening model to detect lymph nodes, which can assist doctors in cancer treatment.Lymph nodes are the human immune system's first line of defense, protecting people from illnesses and virus infections.

  File photo of the Pentagon seen from an airplane over Washington D.C., the United States. (Xinhua/Liu Jie)It is unrealistic to expect China to join U.S.-Russia negotiations on nuclear arms reduction, given the huge gap between Chinese and U.S. nuclear arsenals in terms of quantity and sophistication, a Chinese arms control official said Wednesday.Fu Cong, director-general of the arms control department of the Chinese foreign ministry, made the remarks here at a press briefing on international arms control and disarmament.Fu said the United States has been making a lot of noises about China joining the so-called trilateral negotiations."Hyping up the China factor is nothing but a ploy to divert world attention, and to create a pretext under which the United States could walk away from the New Strategic Arms Reduction Treaty (START)," he said.China's refusal to join the so-called trilateral negotiations doesn't mean that China is shying away from international nuclear disarmament efforts, Fu said, adding China is a strong advocate for nuclear disarmament in the United Nations and at the Conference on Disarmament in Geneva."China initiated the dialogue on nuclear doctrines among the P5, and proposed that the P5 reiterate jointly the formula of 'nuclear war cannot be won, and must never be fought'," Fu said, adding that unfortunately, the United States has refused to recommit itself to this basic truism.China stands ready to discuss all issues related to strategic stability and nuclear risk reduction in the framework of P5, i.e. among China, Russia, the U.S., the UK and France, he said."We urge the United States to respond positively to Russia's call to extend the New START, and on that basis, to further reduce its huge nuclear arsenal," Fu said, quoting figures from renowned international think tanks showing that the number of U.S. nuclear warheads is almost 20 times that of China.Concerning China's accession to the Arms Trade Treaty, Fu said the move is further testimony to China's determination to combat illicit arms trafficking and its commitment to multilateralism and the international arms control regime, representing another concrete step toward implementing the grand vision of building a community with a shared future for humanity.When referring to the Biological Weapons Convention (BWC), the official said the United States has single-handedly blocked the restarting of negotiations on a verification protocol, and more and more questions are being asked about the true nature of the activities conducted in some of the U.S. biological laboratories."We urge the United States to demonstrate more transparency and heed the appeals of the international community in not continuing to block the restarting of the protocol negotiations," Fu added.File photo of the Pentagon seen from an airplane over Washington D.C., the United States.
