Steel-ultra-high-performance concrete (UHPC) composite beams employing single embedded nut bolted shear connectors (SENBs) in full-depth precast deck systems represent a competition attempt recent years, which can fully utilize the exceptional material characteristics of both SENBs and UHPC. Due to demountable SENBs, this innovative beam could be easily deconstructed repair or recycle deteriorated components. However, generally combine tensile loads during service stages. Nevertheless,...

Abstract We propose a novel mechanism to manipulate the electron dynamics at boundary of Brillouin zone (BZ) through resonant excitation induced by ultraviolet (UV) laser pulses in solid high harmonic generation (HHG). When adding weak UV stronger mid-infrared (MIR) driving field, we show that with specific wavelengths generate around Γ point k − space, which facilitates interband transition electrons BZ region. The scheme is not only significant for achieving higher yield, but also exhibits...

<title>Abstract</title> Recent studies have shown that endothelial progenitor cells (EPCs) could enhance osteogenesis of mesenchymal stem (MSCs) through multiple paracrine signals. However, the role EPCs-derived exosomes (EPCs-exos) in has been rarely reported, and little is known regarding their underlying mechanisms. This study attempted to investigate mechanism by which EPCs-exos promotes MSCs. was isolated supercentrifugation characterized western blot, transmission electron microscopy...

Abstract Hybrid simulation is a powerful testing method that combines numerical analysis and physical experiments through on‐line interaction. The substructuring technology enables hybrid to evaluate the structural performance with large‐scale specimens. However, this also increases complexity of specimen boundary conditions. Due limited equipment resources laboratories, not all degrees freedom conditions can be realized during tests, which will induce error experimental restoring forces...
