From December 2011 to May 2014, about 5 fb−1 of data were taken with the BESIII detector at center-of-mass energies between 3.810 GeV and 4.600 study charmonium-like states higher excited charmonium states. The time-integrated luminosity collected sample is measured a precision 1% by analyzing events produced large-angle Bhabha scattering process.
Type Ia supernovae (SN Ia) are the most important standard candles for measuring expansion history of universe. The thermonuclear explosion a white dwarf can explain their observed properties, but neither progenitor systems nor any stellar remnants have been conclusively identified. Underluminous SN proposed to originate from so-called double-detonation dwarf. After critical amount helium is deposited on surface through accretion close companion, ignited causing detonation wave that triggers...
A measurement of the number J/ψ events collected with BESIII detector in 2009 and 2012 is performed using inclusive decays J/ψ. The taken recalculated to be (223.7 ± 1.4) × 106, which good agreement previous measurement, but significantly improved precision due improvements software. determined (1086.9 6.0) 106. In total, measured (1310.6 7.0) where uncertainty dominated by systematic effects statistical negligible.
From 2011 to 2014, the BESIII experiment collected about 5 fb−1 data at center-of-mass energies around 4 GeV for studies of charmonium-like and higher excited charmonium states. By analyzing di-muon process e+e− → γISR/FSRμ+μ−, samples are measured with a precision 0.8 MeV. The energy is found be stable most time during taking.
Variable environments and constrained edge devices pose the significantly challenging task of directly recognizing relative attitude unmanned aerial vehicles (UAVs). Furthermore, datasets UAV landing markers that are accessible to general public scarce. To tackle these challenges, we first constructed a dataset on called marker (ULMD). Then, enhanced You Only Look Once (YOLO) model devise specifically tailored for UAVs, termed YOLO (URA-YOLO). Within URA-YOLO, propose an multiscale feature...
Due to the limitations of pure electric power endurance, turbo-electric hybrid systems, which offer a high power-to-weight ratio, present reliable solution for medium- and large-sized vertical take-off landing (VTOL) aircraft. Traditional energy management strategies often fail minimize fuel consumption across entire flight profile while meeting demands under varying conditions. To address this issue, paper proposes deep reinforcement learning (DRL)-based strategy (EMS) specifically designed...
Blue large-amplitude pulsators (BLAPs) are a newly discovered type of variable star. Their typical pulsation periods on the order few tens minutes, with relatively large amplitudes 0.2-0.4 mag in optical bands, and their rates period changes $10^{-7} yr^{-1}$ (both positive negative). They extremely rare objects attempts to explain origins internal structures have attracted great deal attention. Previous studies proposed that BLAPs may be pre-white dwarfs, masses around $0.3M_\odot$, or...
Employing Eggleton's stellar evolution code, we carry out 150 runs of non-conservative population I binary calculations with the initial primary mass between 1 and 8 M⊙, ratio q=M1/M2 1.1 4 onset Roche lobe overflow (RLOF) at early, middle or late Hertzsprung gap. Convective overshooting is included in our models assume that 50 per cent lost from during RLOF accreted on to secondary. The other system, carrying away same specific angular momentum as centre primary. We find remnant depends...
From the canonical binary scenario, majority of sdBs are produced from low-mass stars with degenerate cores where helium is ignited in a way flashes. Due to numerical difficulties, models generally constructed more massive non-degenerate cores, leaving several uncertainties on exact characteristics sdB stars. Employing MESA, we systematically studied common envelope (CE) ejection channel, and found that CE channel appear form two distinct groups effective temperature-gravity diagram. One...
<i>Context. <i/>Masses are a fundamental parameter, but they not well known for most hot subdwarfs. In general, the mass of subdwarf is derived with asteroseismology or dynamical methods, which it often difficult to obtain necessary data from observations.<i>Aims. <i/>We intend find an approach deriving masses subdwarfs observational in literature.<i>Methods. presented full evolutionary calculations wide range (0.33 1.4 ) Population I metallicity , and obtained relation between...
In the Machine Learning (ML) era, faced with challenges, including exponential multi-sensor data, an increasing number of actuators, and data-intensive algorithms, development Unmanned Aerial Vehicles (UAVs) is standing on a new footing. particular, Flight Management System (FMS) plays essential role in UAV design. However, trade-offs between performance SWaP-C (Size, Weight, Power, Cost) reliability–efficiency are challenging to determine for such complex system. To address these issues,...
A large high-altitude air-shower observatory (LHAASO) is to be built at Shangri-La, Yunnan Province, China. This intended conduct sub-TeV gamma astronomy, and as an important component of the LHAASO project, a water Cherenkov detector array (WCDA) proposed. To investigate engineering issues fully understand technique for detecting air showers, prototype 1% scale LHAASO-WCDA has been Yang-Ba-Jing, Tibet, paper introduces setup studies its performance by counting rate each photomultiplier tube...
In order to investigate the physical and chemical properties of massive star forming cores in early stages, we analyse excitation abundance four organic species, CH3OH, CH3OCH3, HCOOCH3 CH3CH2CN, toward 29 Extended Green Object (EGO) cloud that were observed by our previous single dish spectral line survey. The EGO are found have similar methanol J_3-J_2 rotation temperatures ~44 K, a typical linear size ~0.036 pc, beam averaged several 10^(-9) (the corrected value could reach 10^(-7))....
Context. The companions of the exploding carbon-oxygen white dwarfs (CO WDs) that produce type-Ia supernovae (SNe Ia) have still not been conclusively identified. A red-giant (RG) star can fill this role as mass donor WD − channel for producing SNe Ia has named symbiotic channel. However, previous studies on given a relatively low rate Ia. Aims. We aim to systematically investigate parameter space, Galactic rates, and delay time distributions arising from under revised mass-transfer...
