摘要:NEUTRON RESEARCH | This week, regulators gave the go-ahead to restart a small U.S. research reactor, 2 years after an accident shut it down and cut almost by half the nation's capacity to use neutrons to study materials. The February 2021 incident at the 20-megawatt, neutrongenerating reactor at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, occurred when one of its 30 rodlike, uranium-filled fuel pins popped out of place, overheated, and partially melted....

摘要:Geometry, an ancient yet vibrant branch of mathematics, has important and far-reaching impacts on various disciplines such as art, science, and engineering. Here, we introduce an emerging concept dubbed geometric deep optical sensing that is based on a number of recent demonstrations in advanced optical sensing and imaging, in which a reconfigurable sensor (or an array thereof) can directly decipher the rich information of an unknown incident light beam, including its intensity, spectrum, pola...
