We present the X-ray timing results of new black hole candidate (BHC) MAXI J1535-571 during its 2017 outburst from Hard Modulation Telescope (\emph{Insight}-HXMT) observations taken September 6 to 23. Following definitions given by \citet{Belloni2010}, we find that source exhibits state transitions Low/Hard (LHS) Intermediate (HIMS) and eventually Soft (SIMS). Quasi-periodic oscillations (QPOs) are found in intermediate states, which suggest different types QPOs. With large effective area...
A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams with energy spreads of few per-mille level in a single-stage laser wakefield accelerator. Longitudinal plasma density tailored control relativistic laser-beam evolution, resulting injection, dechirping, and quasi-phase-stable acceleration. With this scheme, peak energies 780--840 MeV, rms 2.4\mbox{\textperthousand}--4.1\mbox{\textperthousand}, charges 8.5--23.6 pC, divergences 0.1--0.4 mrad were...
The megajansky radio burst, FRB 20200428, and other bright bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast (FRBs), but emission site mechanism of FRB-like are still unidentified. Here, we report emergence a pulsar phase magnetar 5 months after 20200428. Pulses were in 16.5 hours over 13 days using Five-hundred-meter Aperture Spherical Telescope, with luminosities about eight decades fainter than pulses emitted narrow window anti-aligned x-ray...
The environment of bone marrow mesenchymal stem cells (MSCs) is hypoxic, which plays an important role in maintaining their self-renewal potential and undifferentiated state. MSCs have been proven to possess immunomodulatory properties used clinically treat autoimmune diseases. Here, we tested the effects hypoxia on examined its possible underlying mechanisms. We found that hypoxic stimulation promoted human gingiva–derived (hGMSCs) by enhancing suppressive hGMSCs peripheral blood...
In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard Modulation Telescope (Insight-HXMT), which was launched on Jun. 15th, 2017. The new method 'Significance Enhancement Pulse-profile Orbit-dynamics' (SEPO) is adopted to determine orbit observations only one pulsar. test, Crab chosen and observed by Insight-HXMT from Aug. 31th Sept. 5th in Using 5-day-long observation data, determined successfully three telescopes onboard - High Energy (HE), Medium...
A bstract This study explores a minimal renormalizable dark matter (DM) model, incorporating sub-GeV Majorana DM and singlet scalar particle ϕ . Using pseudo-scalar interactions (couplings c s p ), we investigate implications for detection, considering -wave, combined ( + wave) contributions in annihilation cross-section, as well loop-correction to DM-nucleon elastic scattering. Identifying broad parameter space (10 MeV < m χ ≲ ) within the 2 σ allowed region, explore scenarios (| | ≫ |,...
Infrared and visible image fusion aims to integrate complementary thermal radiation detailed information enhance scene understanding. Transformer architectures have shown promising performance in this ffeld, but their feed-forward networks struggle model multi-scale features, self-attention often aggregates features using the similarities of all tokens queries keys, which leads irrelevant introducing noise. To address these issues, paper proposes a Sparse Dual Aggregation Transformer-based...
<title>Abstract</title> Infants communicate with others through nonverbal gestures in their early years, expressing needs and emotions gestural signs. But it is very challenging for adults to understand babies who have no language skills. In order better these infant gestures, the author first constructed a dataset (babyhand_gesture), which contains four such as: "happy", "nervous", "sleep" "sleepy". On this basis, paper proposes S-MCCP (Based on StarNet Multi-channel Cartesian product)...
Abstract We performed the broadband (1–100 keV) spectral analysis of first Galactic Be ultraluminous X-ray pulsar (BeULX) Swift J0243.6+6124 observed by Insight-HXMT during 2017−2018 outburst. The results show transitions at two typical luminosities, roughly consistently with those reported previously via pure timing analysis. find that spectrum evolves and becomes softer has higher cutoff energies until luminosity reaches L 1 (∼1.5 × 10 38 erg s −1 ). Afterwards harder lower increases to 2...
Abstract Magnetars are neutron stars with extremely strong magnetic fields, frequently powering high-energy activity in X-rays. Pulsed radio emission following some X-ray outbursts has been detected, albeit its physical origin is unclear. It long speculated that the of magnetars’ signals different from those canonical pulsars, although convincing evidence still lacking. Five months after magnetar SGR 1935+2154's outburst and associated fast burst 20200428, a pulsar phase was discovered. Here...
The long-term evolution of the centroid energy CRSF in Her X-1 is still a mystery. We report new measurement from campaign between Insight-HXMT and NuSTAR performed February 2018. Generally, two satellites show well consistent results timing spectral properties. joint analysis confirms that previously observed long decay phase has ended, line instead keeps constant around 37.5 keV after flux correction.
As an essential task for network management and security, traffic classification has attracted increasing attention in recent years. Traditional methods achieve certain success identifying specific application but fail with un-predefined unknown classes. Existing discovery commonly pick out some unlabeled testing data as part of training to train the models, which is not line real-world open environments. In this paper, we propose a novel scheme named SEEN detection classification. There are...
