And the tech could save lives if used in museums, stadiums, theme parks or schools, the team said, noting its design can inspect bags or luggage without being an exposure to privacy. Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material.

He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill. Superputers which can analyse blood samples and predict which patients are likely to bee seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.【英語】高考英語閱讀理解(科普環(huán)保)精編習(xí)題及解析一、高中英語閱讀理解科普環(huán)保類1．犇犇閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen at risk patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: I am so excited about this form of technology. Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a pletely new example in the way we manage healthcare. He found the technique forecast outes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient. Prof Young said, Instead of waiting for people to get worse, we will be able to treat them earlier.（1）What does the underlined phrase screen in Paragraph2 mean?

These items could include weapons, chemicals, laptops and batteries for bombs, the research team said on Tuesday. The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干擾)caused by two factors of objectsthe material and shape. Most dangerous objects such as weapons are usually metal or liquid, which have significant interference, researchers said. It uses channel state information (CSI) that is readily available in lowcost WiFi devices. This could have a great impact on protecting the public from dangerous objects, said Yingying Chen, a coauthor of the study, There39。s hard to set up expensive screening equipment like what39。 The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Ne
