Abstract For lithium‐sulfur batteries (Li‐S batteries), a high‐content electrolyte typically can exacerbate the shuttle effect, while lean may lead to decreased Li‐ion conductivity and reduced catalytic conversion efficiency, so achieving an appropriate electrolyte‐to‐sulfur ratio (E/S ratio) is essential for improving battery cycling efficiency. A quasi‐solid (COF‐SH@PVDF‐HFP) with strong adsorption high was constructed in situ covalent organic framework (COF) growth on highly polarized...
The physical origin of the Blazhko effect (BL), a phenomenon single or multiple periodic modulation(s) light curve, is under debate. Efficiently identifying and characterizing BL essential in understanding its origins accounting for on numerous applications RRabs era large time-domain surveys. In this study, we make use Resnet 34, well-known convolutional neural network (CNN) architecture, to identify RRab stars with from phased curves collected OGLE. Using reliably classified frequency...
Abstract Thanks to the rapidly increasing time-domain facilities, we are entering a golden era of research on gamma-ray bursts (GRBs). In this Letter, report our observations GRB 240529A with Burst Optical Observer and Transient Exploring System, 1.5 m telescope at Observatorio de Sierra Nevada, 2.5 Wide Field Survey Telescope China, Large Binocular Telescope, Telescopio Nazionale Galileo. The prompt emission shows two comparable energetic episodes separated by quiescence time roughly 400 s....
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed measure, for the first time, occurrence rate orbital distributions of Earth-sized planets. ET consists seven 30cm telescopes, be launched Earth-Sun's L2 point. Six these are transit telescopes with field view 500 square degrees. Staring in direction that encompasses original Kepler four continuous years, this monitoring will return tens...
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility being built jointly by the University of Science and Technology China Purple Mountain Observatory. It equipped with 2.5-meter diameter primary mirror, an active optics system, mosaic CCD camera 0.73 gigapixels on focal plane for high-quality image capture over FOV 6.5-square-degree. anticipated that WFST will be set up at Lenghu site in summer 2023 begin to observe northern sky four optical bands (u, g, r,...
Blade flutter in the last stage is an important design consideration for manufacturers of steam turbines. Therefore, accurate prediction method blade critical. Since majority aerodynamic work contributing to done near tip, resolving tip leakage flow can increase accuracy predictions. The previous research has shown that induced vortices region have a significant influence on field tip. structure due vortex cannot be resolved by unsteady Reynolds-averaged Navier–Stokes (URANS) simulations...
Abstract Particle-in-cell simulations have unveiled that shock-accelerated electrons do not follow a pure power-law distribution, but an additional low-energy “thermal” part, which owns considerable portion of the total energy electrons. Investigating effects these thermal on gamma-ray burst (GRB) afterglows may provide valuable insights into particle acceleration mechanisms. We solve continuity equation in space, from multiwavelength are derived by incorporating processes including...
Blade failure caused by flutter is a major problem in the last stage of modern steam turbines. It because rotor at this always has large scale spanwise, which provides low structural frequency as well supersonic tip speeds. Since most unsteady aerodynamic work done region, transonic tip-leakage flow that influences region could have remarkable effect on stability blades. However, few research had been influence characteristic based full-scale turbine numerical models. In paper, an open 3D...
Shock breakout emission is light that arises when a shockwave, generated by core-collapse explosion of massive star, passes through its outer envelope. Hitherto, the earliest detection such signal was at several hours after explosion, though few others had been reported. The temporal evolution early curves should reveal insights into shock propagation, including asymmetry and environment in vicinity, but this has hampered lack multiwavelength observations. Here we report instant multiband...
