Amorphous SnO thin films were prepared on quartz and 190 nm substrates by electron beam evaporation. X-ray diffraction results reveal that amorphous transforms into polycrystalline (tetragonal litharge structure) after rapid thermal annealing in Ar ambient at starts decomposing (orthorhombic with the expulsion of Sn atoms . The optical properties characterized via spectroscopic ellipsometry. have a higher refractive index narrower bandgap than ones, which is due to polarizability enhancement...
Abstract Clonal demographic traits play important roles in regulating community dynamics. Yet, it remains unclear how the responses of these clonal to drought might depend on previous exposure, and vary among grasslands. We conducted a repeated experiment across four grasslands along an aridity gradient northern China. assessed effects single (precipitation reduction 2021–2022) versus recurrent 2015–2018 bud density, shoot ratio density. Drought reduced density at all most bud‐to‐shoot only...
Background: Mesaconitine (MA), a diester-diterpenoid alkaloid extracted from the medicinal herb Aconitum carmichaelii , is commonly used to treat various diseases. Previous studies have indicated potent toxicity of aconitum despite its pharmacological activities, with limited understanding effects on nervous system and underlying mechanisms. Methods: HT22 cells zebrafish were investigate neurotoxic MA both in vitro vivo employing multi-omics techniques explore potential mechanisms toxicity....
Abstract Grasslands are subject to climate change, such as severe drought, and an important aspect of their functioning is temporal stability in response extreme events. Previous research has explored the impacts drought post‐drought periods on grassland stability, yet mechanistic pathways behind these changes have rarely been studied. Here, we implemented experiment with 4 years 3 recovery assess effects above‐ground net primary productivity (ANPP) its underlying mechanisms. To do so,...
Abstract A redshifted 21 cm line absorption signature is commonly expected from the cosmic dawn era, when first stars and galaxies formed. The detailed traits of this signal can provide important insight on history. However, high-precision measurement hampered by ionosphere refraction absorption, as well radio frequency interference (RFI). Space observation solve problem ionosphere, Moon shield RFI Earth. In paper, we present simulations global spectrum in 30–120 MHz band lunar orbit...
Abstract The cosmic 21 cm signal serves as a crucial probe for studying the evolutionary history of Universe. However, detecting poses significant challenges due to its extremely faint nature. To mitigate interference from Earth’s radio frequency (RFI), ground and ionospheric effects, Discovering Sky at Longest Wavelength (DSL) project will deploy constellation satellites in Lunar orbit, with high-frequency daughter satellite tasked global dawn reionization era (CD/EoR).We intend employ...
Abstract Plant traits are useful proxies of plant strategies and can influence community ecosystem responses to climate extremes, such as severe drought. Few studies, however, have investigated both the immediate lagged effects drought on community‐weighted mean (CWM) traits, with even less research relative roles interspecific vs. intraspecific trait variability in responses. We experimentally reduced growing season precipitation by 66% two cold‐semi‐arid grassland sites northern China for...
The frequent occurrence of cyanobacterial blooms in eutrophic lakes can lead to a high amount biomass aquatic systems, and following cell death, this autochthonous organic matter will eventually decompose. In study, the effect temperature sediment on chemical composition residue was investigated by microcosm experiment. results showed that lowest bloom (CBB) removal efficiency recorded at 32°C regardless presence or absence sediment. Based total carbon, CBB efficiencies were higher than 90%...
ABSTRACT Ground-based observation at frequencies below 30 MHz is hindered by the ionosphere of Earth and radio frequency interference. To map sky these low frequencies, we have proposed Discovering Sky Longest wavelength mission (DSL, also known as ‘Hongmeng’ mission, which means ‘Primordial Universe’ in Chinese) concept, employs a linear array micro-satellites orbiting Moon. Such an can make interferometric observations achieving good angular resolutions despite small size antennas....
Plant traits can be helpful for understanding grassland ecosystem responses to climate extremes, such as severe drought. However, intercontinental comparisons of how drought affects plant functional and functioning are rare. The Extreme Drought in Grasslands experiment (EDGE) was established across the major types East Asia North America (six sites on each continent) measure variability sensitivity extreme, prolonged At all sites, we quantified community-weighted mean composition diversity...
The peri-implant epithelium (PIE) forms a crucial seal between the oral environment and implant surface. Compared with junctional (JE), biological sealing of PIE is fragile, which lacks hemidesmosomes (HDs) internal basal lamina (extracellular matrix containing laminin332, IBL) on upper part interface. In study, we aim to prepare coating good biocompatibility ability immobilize recombinant adenovirus vector LAMA3 (AdLAMA3) for promoting re-epithelization PIE. titanium surface functionalized...
The free-free absorption of low frequency radio waves by thermal electrons in the warm ionized medium our Galaxy becomes very significant at $\lesssim 10$ MHz (ultralong-wavelength), and strength depends on frequency. Upcoming space experiments such as Discovering Sky Longest wavelength (DSL) Farside Array for Radio Science Investigations Dark ages Exoplanets (FARSIDE) will produce high-resolution multi-frequency sky maps ultralong-wavelength, providing a new window to observe Universe. In...
Weak gravitational lensing is an invaluable tool for understanding fundamental cosmological physics. An unresolved issue in weak cosmology to accurately reconstruct the convergence $\ensuremath{\kappa}$ maps from discrete shear catalog with survey masks, which seminal Kaiser-Squire (KS) method not designed address.

Cosmic shear surveys serve as a powerful tool for mapping the underlying matter density field, including non-visible dark matter. A key challenge in cosmic is accurate reconstruction of lensing convergence ($\kappa$) maps from catalogs impacted by survey boundaries and masks, which seminal Kaiser-Squires (KS) method are not designed to handle. To overcome these limitations, we previously proposed Accurate Kappa Reconstruction Algorithm (AKRA), prior-free maximum likelihood map-making method....
In \citep{Qin+}, we attempted to reconstruct the weak lensing convergence map $\hat{\kappa}$ from cosmic magnification by linearly weighting DECaLS galaxy overdensities in different magnitude bins of $grz$ photometry bands. The is correlated with shear at 20-$\sigma$ significance. However, low number density survey prohibits measurement auto-correlation. this paper, apply reconstruction method Dark Energy Survey Year 3 (DES Y3) galaxies DES Data Release 2 (DR2). With greater depth and higher...
