We study the evolution of temporal properties MAXI 1820+070 during 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT a broad energy band 1-150 keV. find different behaviors hardness ratio, fractional rms and time lag before after 58257, suggesting transition occurred at around this point. The observed lags between soft photons 1-5 keV higher bands, up 150 keV, are frequency-dependent: low-frequency range, 2-10 mHz, both timescale dozens seconds but without clear trend...
We firstly reported a single-atom palladium photocatalyst, Pd-Ace-COF, for continuous C-C coupling reaction. Under visible light irradiation, Pd-Ace-COF efficiently drives to form biphenyl with >99% yield. Impressively, exhibits good stability and high activity in the continuous-flow reactor, highlighting its great potential practical applications.
Abstract Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by social and behavioral impairments, emerging in early childhood with unclear causes. The primary aim of this study to investigate shifts the functional gradients underlying hierarchical brain network organization ASD assess their potential contribution clinical symptom severity. Resting-state magnetic resonance imaging was used examine changes across seven major networks cohort 52 individuals 40 healthy...
Aims. Fast Radio Bursts are bright radio transients whose origin has not yet explained. The search for a multi-wavelength counterpart of those events can put tight constrain on the emission mechanism and progenitor source. Methods. We conducted observational campaign FRB 20180916B between October 2020 August 2021 during eight activity cycles Observations were led in band by SRT both at 336 MHz 1547 uGMRT 400 MHz. Simultaneous observations have been optical telescopes Asiago (Galileo...
Fast radio bursts (FRBs) are highly dispersed millisecond-duration bursts. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but the origin cosmological is still not settled. Here we report detection 1863 in 82 hr over 54 days repeating source FRB~20201124A. These show irregular short-time variation Faraday rotation measure (RM), which probes density-weighted line-of-sight magnetic field strength, individual during first 36 days, followed by...
The Insight-Hard X-ray Modulation Telescope (Insight-HXMT) is a broad band and gamma-ray (1-3000 keV) astronomy satellite. High Energy telescope (HE) one of its three main telescopes. detector plane HE composed 18 NaI(Tl)/CsI(Na) phoswich detectors, where NaI(Tl) serves as primary to measure ~ 20-250 keV photons incident from the field view (FOV) defined by collimators, CsI(Na) used an active shield pulse shape discrimination. also omnidirectional monitor. collimators have diverse FOV:...
Probing beam measurement (PBM)-based hybrid beamforming provides a feasible solution for cell-free MIMO. In this letter, we propose novel probing optimization framework where three collaborative modules respectively realize PBM augmentation, sum-rate prediction and optimization. Specifically, the augmentation model integrates conditional variational auto-encoder (CVAE) mixture density networks adopts correlated distribution with full-covariance, which Cholesky-decomposition based training is...
