Background China implemented a partial two-child policy (2013) followed by universal (2015), replacing the former one-child mandated government. The changes affect many aspects of China's population as well maternal and infant health, but their potential impact on birth defects (BDs) remains unknown. In this study, we investigated associations these with BDs in Zhejiang Province, China. Methods findings We used data from BD surveillance system China, which covers 90 hospitals 30 urban...

Abstract The gut microbiome has been linked to host obesity; however, sex-specific associations between and fat distribution are not well understood. Here we show signatures contributing obesity despite both sexes having similar characteristics, including overall abundance diversity. Our comparisons of the taxa associated with android ratio in men women found that there is no widespread species-level overlap. We did observe overlap at genus family levels microbiome, such as Holdemanella...

Abstract The silver‐catalyzed oxidative C(sp 3 )−H/P−H cross‐coupling of 1,3‐dicarbonyl compounds with H‐phosphonates, followed by a chemo‐ and regioselective )−C(CO) bond‐cleavage step, provided heavily functionalized β‐ketophosphonates. This novel method based on readily available reaction system exhibits wide scope, high functional‐group tolerance, exclusive selectivity.

Soft actuators with muscle-like motions have drawn increasing interests in areas such as bioinspired robotics and human–robot communications. Dielectric elastomers resonators (DERs), particular, demonstrate outstanding output performance comparable to natural muscles by adopting a resonant actuation technique. However, their narrow bandwidth results poor adaptability consistency, thus greatly restrict potential for real-world applications. To bridge this gap, article presents nonlinear...

The emerging demand for bioinspired soft robotics requires novel actuators whose performance exceeds conventional rigid ones. Dielectric elastomer (DEAs) are a promising actuation technology with large strain and fast response. Cone DEAs one of the most widely adopted DEA configurations their compact structure force/stroke output several configuration variations developed in recent years. By driving at resonant frequency, cone show significant amplification power outputs, which...

Studies have demonstrated that transmembrane tumor necrosis factor-α (tmTNF-α) plays an anti-inflammatory role. tmTNF-α has a dual function, acting as both signaling ligand and receptor transmits reverse to cells expressing tmTNF-α. However, the role mechanisms of in sepsis are not fully understood. To explore potential lipopolysaccharide (LPS)-induced inflammation. The expression levels TNF-α mRNA were evaluated using flow cytometry real-time PCR, respectively. We employed anti-TNF-α drug...

A model predictive control (MPC) inspired neural network (NN) method is proposed to solve the cooperative problems of vehicle platoon in this paper. The controller design approximate a quadratic programming (QP) solver for MPC problems. However, paper based on data-driven rather than being strictly model-based. Meanwhile, compared QP solver, computational efficiency significantly improved. To ensure asymptotic convergence platoons, terminal penalty matrix and set are taken into optimization...
