BackgroundIn China, over 5 million people have been identified and registered by the public security institutions for Cleaver using illicit drugs.The aim of this study is to compare the influence of different types of illicit drugs on the self-reported mental health of Chinese people.In particular, we want to assess the damage of Heroin, Methamphet
Navigation of images from lightning mapping instruments in geostationary orbits is very important for data applications.However, few scientific peer-reviewed papers have been reported, except a few works in the prelaunch tests.On December 11, 2016, China launched the three-axis stabilized geostationary meteorological satellite Fengyun-4A (FY-4A), w
Optimizing flowering time is crucial for maximizing crop productivity, but gaps remain in the knowledge of the mechanisms underpinning temperate legume flowering.Medicago, like winter annual Arabidopsis, accelerates flowering after exposure to extended cold (vernalization, V) followed by long-day (LD) photoperiods.In Arabidopsis, photoperiodic flow
Phase change materials combined with silicon photonics are emerging as a promising platform to realize miniature photonic devices.We study the basic optical Travel Essentials properties of a subwavelength-dimension silicon ridge waveguide with a 20-nm-thick Ge2Sb2Te5 (GST) top-clad layer.Numerical simulations show that the effective index of the Si
