Interaction of very low-frequency primordial (relic) gravitational waves (GWs) to cosmic microwave background (CMB) can generate B-mode polarization.Here, for the first time we point out that the Bed Rail electromagnetic (EM) response to high-frequency GWs (HFGWs) would produce quasi-B-mode distribution of the perturbative photon fluxes.We study th
Improvement of performance of ultra-high performance concrete based composite material added with nano materials
Ultra-high performance concrete (UHPC), a kind of composite material characterized by ultra high strength, high toughness and high durability.It has a wide application prospect in engineering practice.But there are some defects in concrete.How to improve strength and toughness of UHPC remains to be the target of researchers.To obtain UHPC with BNC
Role of the innate immunity in female reproductive tract
Dishwasher The mucosal immune system in the female reproductive tract (FRT) is well equipped to meet the sexually transmitted pathogens, allogeneic sperm, and the immunologically distinct fetus.Analysis of the FRT indicates that epithelial cells provide a physical barrier against pathogens and microbial infections as well as secretions containing a
Effect of Dielectric Distributed Bragg Reflector on Electrical and Optical Properties of GaN-Based Flip-Chip Light-Emitting Diodes
We demonstrated two types of GaN-based flip-chip light-emitting diodes (FCLEDs) with distributed Bragg reflector (DBR) and without DBR to investigate the effect of dielectric TiO2/SiO2 DBR on optical and electrical characteristics of FCLEDs.The reflector consisting of two single TiO2/SiO2 DBR stacks optimized BNC skt - SMA skt for different central
