The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose underground liquid scintillator detector, was proposed with the determination of neutrino mass hierarchy as primary physics goal. It is also capable observing neutrinos from terrestrial and extra-terrestrial sources, including supernova burst neutrinos, diffuse background, geoneutrinos, atmospheric solar well exotic searches such nucleon decays, dark matter, sterile etc. We present motivations anticipated...
Abstract “A Craftsman Must Sharpen His Tools to Do Job,” said Confucius. Nuclear detection and readout techniques are the foundation of particle physics, nuclear astrophysics reveal nature universe. Also, they being increasingly used in other disciplines like power generation, life sciences, environmental medical etc. The article reviews short history, recent development, trend techniques, covering Semiconductor Detector, Gaseous Scintillation Cherenkov Transition Radiation Readout...
Sb 3+ /Sm co-doping can effectively modulate the luminescence by adjusting energy transfer in Cs 2 NaYCl 6 double perovskites. Two minima excited state of 3 P 1 enable self-trapped exciton emission at low temperatures.
Abstract The Low-Energy X-ray Polarization Detector (LPD) is one of the payloads in POLAR-2 experiment, which planned as an external payload for deployment on China Space Station 2026. LPD specifically designed to observe polarization gamma-ray burst prompt emissions energy range 2–10 keV, with a preliminary design featuring wide field-of-view (FOV) ±45°. This observation achieved using array photoelectric polarimeters. Because FOV detector, nearly all photons impinge detector off-axis....
Abstract Sound‐evoked wakefulness from sleep is crucial in daily life, yet its neural mechanisms remain poorly understood. It found that CaMKIIα+ neurons the temporal association cortex (TeA) of mice are not essential for natural awakening sleep. However, optogenetic activation these reliably induces non‐rapid eye movement (NREM) but rapid (REM) In vivo electrophysiological and calcium recordings further demonstrated TeA monotonically tuned to sound intensity frequency. More importantly, it...
Abstract The ability of the side-on transition radiation detector (TRD) for High Energy Radiation Detector (HERD) to accurately calibrate energy cosmic ray depends on precision in measuring and identifying Transition (TR) photons. This requires maximizing transmittance TR photons sensitive volume collection resulting electrons by detector. An optimization field cage is necessary both aspects. In response need high photon from side a uniform electric compact structure TRD, dual-width strip...
Abstract Synchrotron circular polarization of a nonthermal power-law electron distribution in gamma-ray bursts (GRBs) has been studied. However, some numerical simulations have shown that the resulting electrons is combination thermal component and component. In this paper, we investigate synchrotron using such hybrid energy relativistic within globally toroidal magnetic field GRB prompt optical emission. Our results show compared to solely model, degree (PD) model can vary widely band,...
Abstract The spectral evolution and lag behavior of 92 bright pulses from 84 gamma-ray bursts observed by the Fermi Gamma-ray Burst Monitor (GBM) telescope are studied. These can be classified into hard-to-soft (H2S; 64/92), H2S-dominated-tracking (21/92), other tracking (7/92). We focus on relationship between lags H2S pulses. main trend (lag behavior) is estimated with <?CDATA $\mathrm{log}{E}_{p}\propto {k}_{E}\mathrm{log}(t+{t}_{0})$?> ( $\hat{\tau }\propto {k}_{\hat{\tau...
The low-energy polarization detector (LPD), a payload of the POLAR-2 mission, is soft X-ray with wide field view and large array aimed at measuring transients. These transients exhibit rapid intensity changes several orders magnitude, making it crucial for detectors to have front-end electronics low dead time, fast readout capabilities, high time resolution, good energy resolution. In this article, we present design electronics, which consist rolling shutter CMOS pixel charge sensor...
This paper presents a new method for an inexpensive fabrication of large sized aluminium matrix nanocomposite, namely, the solid–liquid mixed (SLiM) casting technique accompanied with idea carrier ‘protein’ in biochemistry. The results reveal that poor dispersibility and low wettability nanosized Al 2 O 3 particles are obviously improved via agent powder, 0·6 wt-Al –Al-2024 metal nanocomposite (MMNC) uniformly particle distribution is successfully prepared by SLiM process. Compared...
Abstract The sensory neocortex has been suggested to be a substrate for long-term memory storage, yet which exact single cells could specific candidates underlying such storage remained neither known nor visible over century. Here, using combination of day-by-day two-photon Ca 2+ imaging and targeted single-cell loose-patch recording in an auditory associative learning paradigm with composite sounds male mice, we reveal sparsely distributed neurons layer 2/3 cortex emerged step-wise from...
Abstract The High Energy cosmic-Radiation Detection facility (HERD) is a calorimetry-based cosmic-ray detection mission on board China space station. A side-on transition radiation detector (TRD) focuses the TeV energy range calibration of HERD calorimeter with an error less than 10% by measuring Lorentz factor γ high-energy protons. TRD prototype was developed for performance study and tested Deutsches Elektronen-Synchrotron electron beams. In this paper, Monte Carlo simulation based GEANT4...
