hiroshima, nagasaki and l los alamos national laboratory where radiation sickness can happen soon after radiation exposure but that requires a huge wallop, we re talking hundreds of chest x rays to even give the faintest signs of radiation poisoning so this is not something which you get casually. we re talking a tremendous exposure to radiation if the stories are true. as we mentioned, the head of the iaea is going to lead a mission to chernobyl he says as soon as possible, but is there anything the iaea or any other international group can actually do at this point to better secure chernobyl or many of the other plants here in ukraine? i think so. the troops have left chernobyl, and realize that there are thousands thousands of highly radioactive spent fuel rods on site. the accident, in some sense, is not over. the radiation is still burrowing
only after the network is optimized in this way can it correctly identify an unknown x. ray. but how accurate is artificial intelligence compared to a doctor s expertise. we have actually done this test twice of this point once with a set of studies. and i state a set that we had a radiologist label and then we compare the accuracy of the model to the radiologists and we found that they were very similar in terms of accuracy on most pathologies on one of them the model was performing the radiologist not the radiologist where on the model and then we repeated the experiment this time using a dataset from stanford which we recently released which is 200000 chest x. rays and then we had a similar set up where we had subspecialty radiologists these are very uncommon
the light boxes the central object in his stage since installation art works. in an area in one thousand nine hundred eighty two took much of his inspiration from a period of acute illness after completing his studies he spent a lot of time in hospital because of heart problems. the transparency of chest x. rays of the key to his acrylic glass boxes he fills them with various materials. and light sources which can be switched on and off the result organic ever changing works that function in three dimensions. became internationally known with nature peaches alpine in forest ideals on which he mounts objects. is an essential component of his work combined with traditional and
away x. that s when flo noticed something to his left, a man dressed in dark clothing walking backwards just some 10 feet away. the man spun around and turned toward them, and that s when flo sprinted toward him. he pushed him away from the formation, and as he did, he noticed an object under the man s clothing, a bomb. the motorcycles had been a diversion. and at that moment, flo did something extraordinary. he grabbed the bomber by his vest and kept pushing him away. and all those years of training on the track, in the classroom, out in the field, all of it came together in those few seconds. he had the instincts and the courage to do what was needed. one of flo s comrades, sergeant andrew mahoney, had joined in too, and together they shoved the bomber again and again, and they pushed him so hard he fell onto the ground on his chest x
