The effect of Gd, Ce and Y elements on texture, recrystallization mechanical properties Mg–1.5Zn alloys was investigated. results show that the addition in alloy, which rolled at 450 °C subsequently annealed 350 for 1h, can effectively weaken modify basal characterized by splitting pole toward to transverse direction, leading yield tensile strength, highest along rolling direction lowest direction. Besides, unique texture contributes significant improvement elongation room temperature....
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a condition characterized by excessive fat accumulation in the form of triglycerides. The incidence NAFLD and hyperlipidemia, with their associated risks end-stage cardiovascular diseases, increasing rapidly. This study aimed to investigate effects scutellarin on experimental high-fat diet fed chronic stress rats, its possible mechanism. MATERIAL AND METHODS Sprague-Dawley rats were subjected for 12 weeks, administered orally 4 weeks...
<h3>Importance</h3> Evidence on HIV preexposure prophylaxis (PrEP) among Chinese men who have sex with (MSM) is critical to guide its large-scale implementation in low- and middle-income countries. <h3>Objective</h3> To evaluate incident infection, adherence, safety, changes sexual behaviors MSM using daily PrEP (D-PrEP) event-driven (ED-PrEP) 4 cities China. <h3>Design, Setting, Participants</h3> This nonrandomized controlled trial was conducted HIV-seronegative from December 11, 2018,...
Abstract Tracing cellular dynamic changes across conditions, time, and space is crucial for understanding the molecular mechanisms underlying complex biological systems. However, integrating multi-sample data in a unified flexible way to explore heterogeneity remains major challenge. Here, we present Stereopy, versatile framework modeling dissecting comparative spatiotemporal patterns spatial transcriptomics with interactive visualization. To optimize this framework, have developed three key...
The formability of magnesium alloys at ambient temperature can be enhanced by alloying additions such as Ca and RE elements, which is ascribed to the weakened basal texture. To produce alloy sheets with excellent comprehensive performance, evolution texture characterization during fabrication process subsequent effect on mechanical properties are vital controlling factors. In this investigation, three experimental Mg-3Al series were hot rolled annealed 1 mm thickness. microstructure rolling...
An analytical method for calculating the no-load magnetic field of external rotor permanent magnet brushless direct current motor (PMBLDCM) used as in-wheel electric vehicle in stator static coordinate and motion is presented this paper. First, analytic formulas slotless both systems are derived, respectively. Then, complex relative permeance PMBLDCM calculated. Finally, solution derived by applying potential multiplied permeance. In paper, a 46-pole-51-slot taken an example, accuracy...
Background: Erigeron breviscapus (Vant.) Hand-Mazz. is a plant species in the Compositae family. More than ten types of compounds-such as flavonoids, caffeinate esters, and volatile oils-have been identified breviscapus; however, it remains unknown to which compounds are associated with clinical efficacy. In recent years, flavonoids phenolic acids have considered main effective components breviscapus. The metabolism mechanisms these vivo extensively studied improve our understanding drug....
Shale oil is mainly stored in the nano–micro-pores of shale form adsorption or a free state. Among them, only free-state main contributor to production under natural elastic energy. Therefore, it crucial evaluate movability crude effectively. In this paper, focusing on Jurassic reservoir core middle-eastern Sichuan region China, low-field nuclear magnetic resonance (NMR) technology used analyze basic characteristics samples. Experiments NMR one-dimensional and two-dimensional spectrum...
Air-core Tesla transformer combined with semiconductor devices can generate repetitive high-voltage pulses effectively. of spiral type is suitable for operation since its primary voltage relatively low. Based on the double resonance circuit air-core transformer, expressions secondary voltage, current, and maximum rise-rate current are deduced. The effects tuning characteristic output energy efficiency simulated, further verified by experiments. An prototype developed. To achieve operation, a...
An interface for reading the output of nanomagnetic logic (NML) is indispensable in order NML to interact with existing CMOS ICs. Two alternative designs readout circuit (RIC1 and RIC2) RIC are proposed based on dual barriers magnetic tunnel junction (DBs-MTJ), which composed two fixed layers (with anti-parallel magnetisation state) a common free layer. RIC1 utilises same layer DB-MTJ form an up–down structure, whereas RIC2 exploits reversed left–right structure. They utilise three-terminal...
