Feeding aversion in children may progress to severe feeding difficulties.While oral-motor and sensory issues are usually the leading causes, organic etiologies should be considered.This study aimed to assess the prevalence of gastrointestinal conditions in children with severe feeding difficulties.We conducted a retrospective study of 93 children r
Two-dimensional nanopores are very promising for high-permeance molecular sieving, but the molecular backflow from permeate-side to feed-side is not beneficial for improving molecular permeance.We study the quasi-unidirectional molecular transport through a graphene-hexagonal boron nitride bilayer nanopore, starburst halloween mix aiming to realize
A universal phase mismatch compensation method, which can be applied to temperature-insensitive frequency conversion, is experimentally demonstrated.In this method, two nonlinear crystals and an electro-optic crystal are cascaded.The generated phase mismatch in the nonlinear crystal can be well compensated for in the electro-optic crystal, thereby
