Blank handguns are specially designed guns that, like true firearms, can produce a bright flash and a loud explosive sound, but they do not propel any Timer Module projectiles.Although they are considered harmless by the general public, there are reports of serious injuries and even lethal outcomes.We present a homicide case with an unmodified blan
A calibration method for a high-resolution hybrid MIMO turntable radar Timer Module imaging system is presented.A line of small metal spheres is employed as a test pattern in the calibration process to measure the position shift caused by undesired antenna effects.The unwanted effects in the antenna near-field responses are analysed, modelled and s
Study region: The hilly area of Shandong Peninsula is a pivotal apple-producing region in China.However, the precise water sources utilized by the apple trees for transpiration remain poorly understood in this region.Study focus: Here we quantify the water sources used by apple trees in this area using stable isotopic tracing methods.Through on-fie
