We report the non-resonant excitation and probing of the nonlinear nyx 22 brush refractive index change in bulk semiconductors and semiconductor quantum dots through degenerate transient lens spectroscopy.The signal oscillates at the center laser field frequency, and the hyfrodol envelope of the former in quantum dots is distinctly different from t
FeCoNiCrCu high-entropy alloy (HEA) and Cu foils were utilized as the intermediate layer to conduct laser welding of TC4 titanium alloy and Q345 steel.Welding is performed by adding single HEA and Cu/HEA double foils as interlayer respectively.We conducted in-depth studies on the cent dyyni microstructure and mechanical properties of the joint by s
Background: Statins have demonstrated various beneficial clinical outcomes, not only in patients with elevated cholesterol levels but also in those with normal levels, a collective phenomenon known as pleiotropic effects.In the cardiovascular system, statins exhibit numerous pleiotropic effects, including the improvement of endothelial function by
Antimicrobial stewardship programs (ASPs) can lower antibiotic use, decrease medical expenses, prevent the emergence of resistant bacteria, and enhance treatment for infectious diseases.This study summarizes the stepwise implementation and effects of ASPs in a single university-affiliated tertiary care hospital in Korea; it also presents future dir
