Gene-brain-behavior links revealing generative neurophysiological subtypes of suicide-related dysconnectivity in bipolar depression

Suicidal thoughts and behaviors (STBs) in bipolar depression are heterogeneous, but biologically coherent subtypes remain poorly defined. We aimed to identify neurophysiological subtypes of suicide-related dysconnectivity in bipolar depression and examine their gene-brain-behavio...

Octopus-inspired muscle activation unlocks high-DOF motion from a single actuator

While soft robots leverage compliant materials to offer infinite degrees of freedom (DOFs), achieving dexterous motions usually requires numerous actuators, making the robot bulky, complex to assemble, and discontinuously segmented. Here, inspired by the octopus neuromuscular jun...

Effect of dolomite and kaolin on pollutant emissions and ash agglomeration during pressurized oxy-fuel co-firing of chicken manure and lignite

Against the background of carbon neutrality, chicken manure is a promising animal-derived biomass for cleaner energy recovery, but its high ash and alkali contents cause pollutant-control and agglomeration problems during fluidized-bed utilization. This study compared dolomite an...

Self‐Filtering InGaN/GaN Multiple Quantum Wells Ultraviolet Photodetector With 12 nm Narrowband and 82 ns Ultrafast Response
