Changes in orbital angular momentum distribution of a twisted partially coherent array beam in anisotropic turbulence.

Based on the generalized Huygens Fresnel integral, we derive the analytical formula of the cross-spectral density of a twisted partially coherent array beam propagating in non-Kolmogorov anisotropic turbulence, and investigate the changes in orbital angular momentum (OAM). The results show that the anisotropy of the turbulence causes different effects in horizontal and vertical directions. The spectral density distribution of twisted partially coherent array beam in turbulence presents self-splitting and rotation, which combines the interesting effects of the twist phase and coherent structure.

Mapping the spin angular momentum distribution of focused linearly and circularly polarized vortex fields.

Using the previously proposed spin-resolved near-field scanning optical microscopy (NSOM) technique, we mapped the spin angular momentum (SAM) axial component () distributions of tightly focused linearly and circularly polarized vortex beams. The system's effectiveness was confirmed in our previous article by mapping various tightly focused cylindrical vector vortex beams. The SAM of different focused vortex light fields is essential in the research of near-field spin optics and topological photonics.

Effects of a transitional care program for individuals with limbs disabilities living in a rural community: A randomized controlled trial.

Background: Transitional care (TC) has been proven to be effective in addressing fragmented care and preventing adverse outcomes for chronically ill patients transitioning from hospital to home, but the definitive description of TC that was used successfully for individuals with limbs disability has not been formed in the context of health care reform in China.

Objective: The aim of this study was to evaluate the effect of a TC program on health outcomes in individuals with limbs disability based on an original community for healthcare.

Method: It was a randomized controlled trial.

Microstructure, mechanical, corrosion properties and cytotoxicity of beta‑calcium polyphosphate reinforced ZK61 magnesium alloy composite by spark plasma sintering.

Magnesium alloy (ZK61) and beta-tricalcium phosphate (β-TCP) composite ZK61/xβ-TCP (x = 0, 5, 10, 15 wt%) are fabricated using spark plasma sintering (SPS). In this study, the microstructure, mechanical properties, degradation behavior in simulated body fluid and cytotoxicity tests of composite were investigated. The results show that when the content of β-TCP was 5 wt%, which could be evenly distributed on the boundary of ZK61 particles.

N-Bromosuccinimide-Induced C-H Bond Functionalization: An Intramolecular Cycloaromatization of Electron Withdrawing Group Substituted 1-Biphenyl-2-ylethanone for the Synthesis of 10-Phenanthrenol.

An NBS-induced intramolecular cycloaromatization for the synthesis of 10-phenanthrenols from electron-withdrawing group substituted 1-biphenyl-2-ylethanones is described. The in situ generated bromide was designed to act as an initiator for the radical C-H bond activation. An oxidative cross-dehydrogenative coupling reaction of a highly active C-H bond with an inert C-H bond readily occurs under mild conditions without the need for transition metals or strong oxidants.
