Toroidal dipole resonances enhanced second-harmonic generation with shallow etching of lithium niobate metasurface.

Lithium niobate (LiNbO) has shown great potential for applications in nonlinear metasurfaces, thanks to its large second-order nonlinear coefficients and high integration capabilities. Optical resonances play a crucial role in further enhancing the nonlinear optical responses of LiNbO metasurfaces (LNMS). In this study, both numerically and experimentally, we designed and fabricated a metasurface structure that supports toroidal dipole (TD) resonance to enhance second-harmonic generation (SHG).

Effects of Neuromuscular Electrical Stimulation on Quadriceps Femoris Muscle Strength and Knee Joint Function in Patients After ACL Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Quadriceps weakness is a common barrier to effective rehabilitation after anterior cruciate ligament (ACL) surgery. Neuromuscular electrical stimulation (NMES)-the application of electrical currents to induce muscle contraction-has been used as part of the postoperative rehabilitation regimen.

Purpose: To investigate the effects of NMES on the recovery of quadriceps strength and knee function after ACL surgery.

Best Practice Guidelines for Collecting Microbiome Samples in Research Studies.

Microbiome research has the potential to provide valuable information regarding the complex relationship between microbial communities and the human body. To help facilitate the translation of this potentially revolutionary research to clinical medicine, common guidelines and best practices are necessary. These guidelines should be based on the key findings of recent research in the field and address the primary areas of discrepancy in the previously published literature.

An effective antiviral strategy based on silence of susceptibility genes through cucumber mosaic virus (CMV) attenuated vaccine vector.

Plant viruses represent a major threat to agriculture, affecting a wide range of crops with substantial economic losses. This study presented a novel strategy for managing plant viral diseases through the development an attenuated vaccine utilizing cucumber mosaic virus (CMV) for virus-induced gene silencing (VIGS) targeting susceptibility gene. TOBAMOVIRUS MULTIPLICATION 2A (TOM2A) gene was identified as a critical factor that enhances susceptibility to TMV infection in plants.

Construction of CuMoS/ZnO Heterostructures and Mechanism of Photocatalytic Hydrogen Production.

Constructing wide and narrow band gap heterogeneous semiconductors is a method to improve the activity of photocatalysts. In this paper, CMS/ZnO heterojunctions were prepared by solvothermal loading of ZnO particles on the surface of CuMoS nanosheets. The photocatalytic H precipitation rate is about 545 μmol·g·h, which is 6.
