Cell metabolism plays a crucial role in regulating the pluripotency of human embryonic stem cells (hESCs). Chlorogenic acid (CGA), an essential dietary polyphenol, exhibits diverse pharmacological effects on regulation. This study examines CGA cell hESCs using H9 model. At concentration 100 µg/ml, showed low toxicity and had no impact viability cells. Furthermore, it promotes NANOG expression. Importantly, enhances Fatty β-oxidation (FAO), thus promoting proliferation lipid synthesis...
More attention has been paid to the high-speed generator for its many merits, such as easy install, high efficiency and power density etc. However, due rotor speed frequency of stator winding current, design a is much more difficult quite different from designing conventional with low frequency. The features considerations PM generators driven by micro turbines are introduced in this paper. choice structure, core winding, bearing structure control system discussed some detail.
In recent years, with the rapid development of solar energy and other renewable energy, PV grid connected power generation technology has more attention. Grid inverter is core system.

Abstract. The effective segmentation of point clouds is a prerequisite for surface reconstruction, blind spot repair, and so on. Among them, regional growth widely used due to its simple easy implement algorithm. However, the traditional algorithm often causes problems such as over-segmentation or voiding result instability local features cloud unreasonable selection initial seed nodes. In view above shortcomings, this paper proposes an improved region growing Firstly, by calculating...
An efficient and accurate traffic monitoring system often takes advantages of multi-sensor detection to ensure the safety urban traffic, promoting accuracy robustness target tracking. A method for using Radar-Vision Fusion Path Aggregation Fully Convolutional One-Stage Network (RV-PAFCOS) is proposed in this paper, which extended from (FCOS) by introducing modules radar image processing branches, radar-vision fusion path aggregation. The branch mainly focuses on modeling based spatiotemporal...
Arc fault detection system (AFDS) is a device intended to protect the power against arc that may cause fire. When there an fault, scale of current lower than initialization most protection devices installed in lowers, hence AFDS effective detect successfully and interrupt circuit time. The characteristics arc, how it ignites, what losses were discussed. basic structure primary principles proposed. For efficiently realizing global optimization, single function problem conventional interrupter...
