Abstract In this paper, a hybrid approach was employed by integrating high‐modulus, high‐tensile‐strength carbon fiber fabric (CFF) with low‐density, high‐toughness silk nonwoven (SNWF) to fabricate CFF‐SNWF reinforced epoxy (CFF‐SNWF/EP) composites. Through the surface freeze‐induced self‐assembly process, multiscale modified layers were successfully constructed on surfaces of both CFF and SNWF. This novel effectively enhanced interfacial strength fibers (HFs). Comparing performance...
Stochastic gravitational-wave (GW) background (SGWB) contains information about the early Universe and astrophysical processes. The recent evidence of SGWB by pulsar timing arrays in nanohertz band is a breakthrough GW astronomy. For ground-based detectors, while data analysis, can be masked loud events from compact binary coalescences (CBCs). Assuming next-generation detector network, we investigate potential for detecting cosmological with non-CBC origins subtracting recovered foreground...
New concepts for observing the gravitational waves (GWs) using a detector on Moon, such as Lunar Gravitational-wave Antenna (LGWA), have gained increasing attention. By utilizing Moon giant antenna, LGWA is expected to detect GWs in frequency range from 1 millihertz (mHz) several hertz, with optimal sensitivity decihertz band. Despite debated formation and evolution channel of intermediate-mass black holes (IMBHs) masses $[10^2, 10^5]\ {\rm M_\odot}$, binary systems containing at least one...
Abstract Lorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined LV energy scale as E ≃ 3.60 × 10 17 GeV using Fermi Gamma-ray Space Telescope (FGST) data. This study updates time-delay model reaffirms these findings with new observations. High-energy from GRBs at TeV bands are analyzed, including 99.3 photon GRB 221009A (FGST), 1.07 190114C (MAGIC), 12.2 (LHAASO). Our analysis,...
High-energy photons of gamma-ray bursts (GRBs) might be emitted at different intrinsic times with energy dependence the source. In this letter, we expand model from previous works on testing Lorentz Invariance Violation (LV) observed GRB data Fermi Gamma-ray Space Telescope. We reanalyze full Bayesian parameter estimation method and get consistent results by assuming that time delays are due to an LV term a constant delay term. Subsequently, neglect effect only consider effect. assume common...
Abstract Previous research on Lorentz invariance violation in photons from gamma-ray bursts (GRBs) suggested a scenario where multi-GeV could be emitted before lower-energy at the GRB source frame. This implies existence of new preburst phase addition to traditionally identified prompt and afterglow stages observed earlier studies. In this study, we present direct evidence for novel GRBs based recent observations 221009A. Our analysis leverages data Fermi Gamma-ray Burst Monitor Large Area...

With the advancement of ultra-precision machining, lenses with three-dimensional microstructures have gradually emerged and are widely used in near-eye display devices, infrared imaging, solar concentrators, other application fields. However, various parameters microstructure arrays, such as corner radius defects on working surface, can all impact imaging quality to varying degrees. Therefore, systematically studying effects these is significant importance for optimizing design enhancing...
Abstract Qingdao is the first city in China to fully implement long-term care insurance, and its system has important reference significance for healthy equity development of elderly population Shandong Province. The policy divides insurance benefits into medical services nursing services, with service fee being 3,500 yuan per year employees 3,000 residents, 18,000 5,000 residents. According forecasts, GDP Province expected reach 14,145.63 billion 2035. Therefore, according ratio one...
In order to improve the intelligence and water-saving efficiency of agricultural irrigation, an intelligent irrigation machine based on STM32 microprocessor with remote monitoring control functions is proposed in this paper. This solution uses sensing technology WiFi module achieve accurate farmland water control. Natural factors such as soil moisture, ambient temperature humidity, light can be monitored by sensors determine crop watering needs. After testing, system works stably level...
