Microcavity-assisted multi-resonant metasurfaces enabling versatile wavefront engineering.

Metasurfaces have exhibited exceptional proficiency in precisely modulating light properties within narrow wavelength spectra. However, there is a growing demand for multi-resonant metasurfaces capable of wavefront engineering across broad spectral ranges. In this study, we introduce a microcavity-assisted multi-resonant metasurface platform that integrates subwavelength meta-atoms with a specially designed distributed Bragg reflector (DBR) substrate.

Trends in the use of psychotropic drugs in people with intellectual disability in Taiwan: a nationwide outpatient service study, 1997-2007.

This study aims to examine trends in outpatient psychotropic drug use among people with intellectual disabilities in Taiwan. The NHI outpatient medication records between January 1, 1997 and December 31, 2007 for people with intellectual disabilities were analyzed to observe the percent change, prevalence and prescription trends in psychotropic drugs. The overall prevalence of psychotropic medication increased from 17.

In vivo proton magnetic resonance spectroscopy of large focal hepatic lesions and metabolite change of hepatocellular carcinoma before and after transcatheter arterial chemoembolization using 3.0-T MR scanner.

Purpose: To investigate the value of in vivo proton magnetic resonance spectroscopy (MRS) in the assessment of large focal hepatic lesions and to measure the metabolite change of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) using 3.0-T scanner.

Materials And Methods: In this prospective study, 43 consecutive patients with large (not less than 3 cm in diameter) hepatic tumors and eight normal volunteer were included.
