Hematopoietic stem cell (HSC) aging is accompanied by hematopoietic reconstitution dysfunction, including loss of regenerative and engraftment ability, myeloid differentiation bias, elevated risks malignancies. Gut microbiota, a key regulator host health immunity, has recently been reported to affect hematopoiesis. However, there currently limited empirical evidence explaining the direct impact gut microbiome on In this study, we performed fecal microbiota transplantation (FMT) from young...
In this paper we review the basic theoretical aspects as well some important experimental results of band anticrossing effects in highly electronegativity-mismatched semiconductor alloys, such GaAs1−xNx and InyGa1−yAs1−xNx. The many-impurity Anderson model treated coherent potential approximation is applied to these which metallic anion atoms are partially substituted by a electronegative element at low concentrations. Analytical solutions Green's function provide dispersion relations state...
We show that incorporation of nitrogen in Ga1−xInxAs to form Ga1−xInxNyAs1−y alloys leads a splitting the conduction band into two nonparabolic subbands. The can be described terms an anticrossing interaction between narrow localized states and extended conduction-band semiconductor matrix. downward shift lower subband edge accounts for N-induced reduction fundamental band-gap energy. An analysis relationship demonstrates energetic location valence is nearly independent N content alloys.
Global sea level rise caused by climate change is not uniform geographically, which emphasizes the importance of considering relative (RSL) when assessing risks associated with for different regions and scales. However, our understanding impacts on coastal zones still limited since lacking information sea-level (RSLC) at a high resolution. To address this, we combined VLM from Navigation Satellite System global mean trend measured satellite altimetry to produce RSL velocity in 0.25-degree...
The utilization of artificial intelligence for the differentiation benign and malignant breast lesions in multiparametric MRI (mpMRI) assists radiologists to improve diagnostic performance.To develop an automated deep learning model lesion segmentation characterization evaluate performance AI models radiologists.For segmentation, 2,823 patients were used training, validation, testing VNet-based models, average Dice similarity coefficient (DSC) between manual by mask generated VNet was...
This work used mechanical alloying combined with NH3·H2O treatment to strengthen GCr15 steel balls. First, balls a Ti coating were fabricated by alloy considering two structures of jars: one is the ordinary jar and second self-made special (SMA). Then, deposited coatings removed dropping during ball milling process. Surprisingly, diffusion layer obtained on surface In particular, layers in samples processed jars show thickness approximately 3.2 μm. Mechanical Properties, such as grain,...
We present the results of optical studies on properties GaN grown by low-pressure metalorganic chemical-vapor deposition, with emphasis issues vital to device applications such as stimulated emission and laser action well carrier relaxation dynamics. By pumping, lasing were investigated over a wide temperature range up 420 K. Using picosecond streak camera, free bound exciton decay times examined. In addition, effects pressure interband transitions associated impurity/defect states studied...
Dilute InNxP1−x alloy thin films were synthesized by nitrogen ion implantation into InP using doses corresponding to N mole fraction up 0.048. In the with highest contents, it was shown modulated photoreflectance that fundamental band gap energy decreased 180 meV. The reduction is similar in magnitude observed epitaxially grown III–NxV1−x alloys. layers thermally stable an annealing temperature of 850 °C. Using recently developed anticrossing model which relates content, we estimate maximum...
Along with rapid population ageing and extensive policy changes, Chinese attitudes towards elderly care responsibility are shifting. Using nationally representative survey data, this study finds that the proportion of people holding traditional view children should be main providers decreased from 57 per cent in 2010 to 50 2015. Further analyses show above beyond individual factors such as gender, age marital status, social policies institutions have influenced people's attitudes. Pension...
Abstract Aims This study aims to investigate the safety, tolerability, efficacy, and pharmacokinetics of Pynegabine as an add‐on therapy in treatment focal epilepsy. Methodology is a protocol phase‐IIa, randomized, double‐blinded, placebo‐controlled, multicenter patients with epilepsy from multiple centers China who have been treated at least 2 ASMs without effective control. The involves 8‐week run‐in period stable use previous medications. Patients are then randomized receive either or...
Women who are pregnant again after a prior cesarean section faced with the choice between vaginal trial and another section. Vaginal delivery is safer for mothers babies, but face risk of labor failure. Predictive models can evaluate success rate section, which will help obstetricians women choose appropriate method. To review existing prediction cesaean. Seven databases, including CNKI, Wanfang Data, Chinese Science Technology Periodical Database, China Biomedical Literature PubMed, Embase,...
We present the results of pressure-dependent photoluminescence (PL) studies single-crystal InxGa1−xN (0⩽x<0.15) films grown on top thick GaN epitaxial layers by metalorganic chemical vapor deposition with sapphire as substrates. PL measurements were performed at 10 K a function applied hydrostatic pressure using diamond-anvil-cell technique. The luminescence emissions from epifilms found to shift linearly toward higher energy increasing pressure. By examining dependence spectra,...
The energy position of the optical absorption edge and free carrier populations in InxGa1-xN ternary alloys can be controlled using high 4He+ irradiation. blue shift after irradiation In-rich material (x > 0.34) is attributed to band-filling effect (Burstein-Moss shift) due native donors introduced by In Ga-rich material, measurements show that irradiation-introduced defects are inside bandgap, where they incorporated as acceptors. observed irradiation-produced changes excellent agreement...
