An increasing number of evidences indicate microbes are implicated in human physiological mechanisms, including complicated disease pathology. Some have been demonstrated to be associated with diverse important diseases or disorders. Through investigating these disease-related microbes, we can obtain a better understanding mechanisms for advancing medical scientific progress terms diagnosis, treatment, prevention, prognosis and drug discovery. Based on the known microbe-disease association...
Most metals including Mg alloys have a longstanding dilemma of strength-ductility trade-off, which is hindering their wider applications. In this study, we propose gradient heterogeneous grain (GHG) structure for evading trade-off and ultrasonic severe surface rolling attempted to construct novel in ZE41 alloy. Here, the GHG combine benefits introduce large microstructural heterogeneities. Compared coarse-grain heterogeneous-grain structured alloys, one exhibits dramatical enhancement...
Inertial microfluidics, as an efficient method for the manipulation of micro-/nanoparticles, has garnered significant attention due to its advantages high throughput, structural simplicity, no need external fields, and sheathless operation. Common structures include straight channels, contraction–expansion array (CEA) spiral serpentine channels. In this study, we developed a CEA channel embedded with hook-shaped microstructures modify characteristics vortices. Through experimental studies,...
Deubiquitinating enzymes play crucial roles in various cellular activities, yet their involvement central nervous system (CNS) vascularization and barrier function remains elusive. Canonical Wnt signaling is essential for proper CNS maintenance. Using a loss-of-function screening Wnt-signaling activity, we identified ubiquitin-specific peptidase 9 X-linked (USP9X) as key regulator brain endothelial cells (BECs). Endothelium-specific Usp9x knockout mice exhibit reduced compromising during...
Abstract There is a pressing need for high-performance, high-strength low-alloy structural (HSLA) steels in various engineering fields, such as hydraulic components, machinery, bridges, ships, and pressure vessels. In this study, gradient dislocation-cell structure introduced into an HSLA steel through ultrasonic severe surface rolling. The cell size approximately 614 nm at the topmost layer, increases with increasing depth. Most of walls have misorientation ranging from 2° to 15°,...
The high-power long pipeline liquid supply system is subject to strongly time-varying loads, resulting in severe pressure surges that affects its reliability. Facing complex unsteady flow characteristics, accurately mastering the transfer, evolution, and response law of high-pressure, large-flow premise for realizing accurate control ensuring quality. In this study, hydraulic support taken as research object, a dynamics model established. Numerical solutions are obtained using Method...
Implementing an energy recovery system (ERS) is effective solution to improve efficiency for hydraulic excavators (HEs). A flywheel (FERS) proposed based on this concept. pump motor (PM) employed as the conversion component and a used storage component. Since pressure low because bucket usually empty boom lowers, relatively large PM should be in FERS. To overcome drawback, novel compound integrating flow regeneration (FFERS) paper. The working principle of analyzed detail. introduction has...
The surface precision and mechanical properties were the bottleneck of laser shock imprinting extensive application in micro/nano manufacturing. In this work, high-quality precise nanoscale line textures fabricated on aluminum foil, influence pulse energy pre-shock processing preparation was also investigated experimentally. morphology texture characterized by scanning electron microscope (SEM) atomic force (AFM), which obtained best parameter. microstructure dislocation changes imprinted...
Silicon undergoes a brittle-to-ductile transition as its characteristic dimension reduces from macroscale to nanoscale. The thorough understanding of the plastic deformation mechanism silicon at nanoscale is still challenging, although it essential for developing Si-based micro/nanoelectromechanical systems (MEMS/NEMS). Given wide application in extreme conditions, is, therefore, highly desirable reveal nanomechanical behavior cryogenic temperature elevated temperature. In this paper,...
