Wide bandgap semiconductor AlGaN alloys have been identified as key materials to fabricate solar-blind ultraviolet photodetectors (SBUV PDs). Herein, a self-driven SBUV polarization-sensitive PD (PSPD) based on semipolar (112̅2)-oriented AlGaN films is reported. Using the flow-rate modulation epitaxy method, the full widths at half maximum (FWHMs) for the obtained (112̅2) AlGaN along [112̅3̅] and [11̅00] rocking curves are 0.

Purpose Of Review: To share current concepts and provide an overview of the contextual issues and nutrition practices in critically ill patients in resource-limited settings (RLSs)/low- and middle-income countries (LMICs). Most of the world's population reside in these settings which also carries the greatest burden of critical illness.
Recent Findings: There is a paucity of evidence on nutrition practice in critically ill patients in RLSs and international guidelines are largely based on evidence derived from high-income countries (HICs).
Deconvoluting thermomechanical effects in X-ray diffraction data using machine learning.

X-ray diffraction is ideal for probing the sub-surface state during complex or rapid thermomechanical loading of crystalline materials. However, challenges arise as the size of diffraction volumes increases due to spatial broadening and because of the inability to deconvolute the effects of different lattice deformation mechanisms. Here, we present a novel approach that uses combinations of physics-based modeling and machine learning to deconvolve thermal and mechanical elastic strains for diffraction data analysis.

Circular RNAs (circRNAs), as a class of noncoding RNA molecules with a circular structure exhibit high stability and spatiotemporal-specific expression, making them ideal cancer biomarkers for liquid biopsy. Herein, a new photoelectrochemical (PEC) biosensor for a highly sensitive circRNA assay in the whole blood of lung cancer patients was designed based on CRISPR/Cas13a-programmed Cu nanoclusters (Cu NCs) and a -scheme covalent organic framework/silver sulfide (T-COF/AgS) composite. This -scheme T-COF/AgS composite accelerates electron transfer and produces an excellent initial photocurrent.

Despite initial non-operative management, subsequent corrective osteotomy was required due to malunion. Eighteen months later, the patient presented with an inability to extend the thumb, leading to a diagnosis of extensor pollicis longus (EPL) tendon rupture.
