The Korea Invisible Mass Search (KIMS) experiment presents new limits on the weakly interacting massive particle (WIMP)-nucleon cross section using data from an exposure of 3409 kg·d taken with low-background CsI(Tl) crystals at Yangyang Underground Laboratory. most stringent limit spin-dependent interaction for a pure proton case is obtained. DAMA signal region both spin-independent and interactions WIMP masses greater than 20 GeV/c2 excluded by single crystal scintillators.Received 3 April...
SARS-CoV (the SARS-Associated Coronavirus) was reported as a novel virus member in the coronavirus family, which cause of severe acute respiratory syndrome. Coronavirus replication occurs through unique mechanism employing Leader sequence transcripts when initiating transcription from genome. Therefore, we cloned SARS-CoV(BJ01), is identical to that identified SARS-CoV(HKU-39849), and constructed specific siRNA targeting sequence. Using EGFP RFP reporter genes fused with sequence,...
On 2018 Feb. 4.41, the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered ASASSN-18bt in K2 Campaign 16 field. With a redshift of z=0.01098 and peak apparent magnitude B_{max}=14.31, is nearest brightest SNe Ia yet observed by Kepler spacecraft.

Abstract Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically confirmed Type Ia supernova (SN Ia) observed in Kepler field. The data revealed an excess emission its early light curve, allowing us to place interesting constraints on progenitor system. Here we present extensive optical, ultraviolet, and near-infrared photometry, as well dense sampling of optical spectra, for this object. SN relatively normal photometric evolution, with a rise time 18.3 ± 0.3 days Δ m 15 ( B ) =...
Abstract Larch trees are widely used in afforestation and timber plantations. Yet, little is known on how planted larch cope with increasing drought. We a tree-ring network of 818 from 31 plantations spanning most the distribution Larix principis-rupprechtii to investigate extreme drought influences radial growth northern China. found that summer drought, rather than temperature or precipitation, had strongest relationship throughout region. Drought increased frequency recent decades,...
We present our photometric and spectroscopic observations on the peculiar transient AT2018cow. The multi-band photometry covers from peak to $\sim$70 days spectroscopy ranges 5 $\sim$50 days. rapid rise ($t_{\mathrm{r}}$$\lesssim$2.9 days), high luminosity ($M_{V,\mathrm{peak}}\sim-$20.8 mag) fast decline after make AT2018cow stand out of any other optical transients. While we find that its light curves show resemblance those type Ibn supernovae. Moreover, spectral energy distribution...
ABSTRACT Background Cachexia is a wasting syndrome associated with imbalanced energy metabolism and loss of adipose muscle tissues contributes to morbidity mortality in ageing as well patients severe chronic diseases, including cancer. At present, there are no treatments addressing cachexia that have reached validation be used the clinic. In this study, we investigate protective role SIRT6, an important regulator homeostasis health preservation, against Lewis lung carcinoma (LLC)–induced...
We aim to participate in the calibration of X-ray photon count rate halo mass scaling relation galaxy clusters selected first eROSITA All-Sky Survey on western Galactic hemisphere (eRASS1) using weak-lensing (WL) data from fourth release Kilo-Degree (KiDS-1000) . therefore measured radial shear profiles around eRASS1 background galaxies KiDS-1000 as well cluster member contamination. Furthermore, we provide consistency checks with other stage-III surveys that take part Dark Energy Year 3...
Near-infrared II (NIR-II) microscopy, which enables in vivo deep-tissue visualization of vasculature and cell activities, has been a promising tool for understanding physiological mechanisms. However, the volumetric image speed current NIR-II microscopy is hindered by scanning strategy, causing limitations observing instantaneous biological dynamics 3D space. Here, we developed light-field (LFM) based on selective illumination self-supervised implicit neural representation...
Despite cisplatin has been widely used in the treatment of various cancers, noteworthy nephrotoxicity greatly constrained its clinical value. For this reason, finding novel targeted therapies to attenuate should be pretty significant. Our previous study found that histone deacetylase sirtuin 6 (SIRT6) could an ideal target for cisplatin-induced acute kidney injury. In study, we explored protective effects ellagic acid, a natural polyphenol compound activates SIRT6, on nephrotoxicity....
ABSTRACT SN 2018hti is a Type I superluminous supernova (SLSN I) with an absolute g-band magnitude of −22.2 at maximum brightness, discovered by the Asteroid Terrestrial-impact Last Alert System in metal-poor galaxy redshift 0.0612. We present extensive photometric and spectroscopic observations this supernova, covering phases from ∼−35 d to more than +340 r-band maximum. Combining our BVgri-band photometry Swift UVOT optical/ultraviolet photometry, we calculated peak luminosity as ∼3.5 ×...
Tsinghua University-Ma Huateng Telescopes for Survey (TMTS), located at Xinglong Station of NAOC, has a field view upto 18 deg^2. The TMTS started to monitor the LAMOST sky areas since 2020, with uninterrupted observations lasting about 6 hours on average each area and cadence 1 minute. Here we introduce data analysis preliminary scientific results first-year observations, which covered 188 plates ( 1970 deg^2). These have generated over 4.9 million light curves, least 100 epochs them....
Time-domain (TD) spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) can provide accurate and high-cadence radial velocities (RVs). In this work, we search for binaries with compact components RV monitoring method by using LAMOST TD survey of four $K$2 plates. Three binary systems including an unseen white dwarf or neutron star are found. For each system, estimate stellar parameters visible orbital parameters, finally calculate mass function minimum...
Structural coloration as the most possible way to realize ecofriendly dying process for textiles or fabrics has attracted significant attention in past decades. However, photonic crystals (PCs) are a typical example of materials with structural color usually located on surface textiles, which make them not stable when rubbed, bent, washed due weak interaction between PC coatings and fabrics. Here, double networks were constructed first time via hydrogen bond by introducing tannic acid (TA)...
We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through first 180 days. does not show signs of narrow, high-ionization emission lines in early optical spectra, yet lightcurve evolution suggests that an extra energy source circumstellar medium (CSM) interaction must be for at least 2 days explosion. Modeling indicates a ~500R$_{\odot}$ progenitor radius, consistent with rather compact red...
Little is known about the diversity in light curves of GRB-SNe, including whether curve SN 1998bw can be used as a representative template or there luminosity-decline rate relation akin to that SNe Ia.

ABSTRACT We present optical and ultraviolet photometry, as well spectra, for the type II supernova (SN) 2015bf. Our observations cover phases from ∼2 to ∼200 d after explosion. The first spectrum is characterized by a blue continuum with blackbody temperature of ∼24 000 K flash-ionized emission lines. After about 1 week, spectra SN 2015bf evolve like those regular II. From luminosity narrow component H α, we deduce that mass-loss rate larger than ${\sim}3.7\times 10^{-3}\, {\rm M_\odot \,...
