Data-Driven Machine Learning Strategy for Designing Metal-Ion-Doped γ-BiMoO Photocatalysts to Enhance Degradation Performance.

Doped semiconductors are often used to improve photocatalytic efficiency and address the challenges of easy recombination of electron-hole pairs and poor photoluminescence. However, the reproducibility and complexity of experimental studies result in time-consuming and less cost-effective studies, and it is difficult to gain insights into the intrinsic properties of doped photocatalysts to control their performance. Introducing a machine learning approach, we constructed a photocatalytic model of transition-metal- and rare earth metal-ion-doped γ-BiMoO.

Correlation analysis of key genes and immune infiltration in visceral adipose tissue and subcutaneous adipose tissue of patients with type 2 diabetes in women.

Immune cell infiltration into adipose tissue (AT) is a key factor in type 2 diabetes (T2DM). However, research on the impact of fat distribution on immune cells and immune responses in women is still lacking. This study used enrichment, protein-protein interaction network, immune cell infiltration, and correlation analysis to compare the similarities and differences between the transcriptome data of visceral AT (VAT) and subcutprotein-proteinaneous AT (SAT) obtained from the omprehensive database of gene expression in women with non-T2DM and T2DM.

Sport training of axial rotation affects spatial ability: Evidence from behavior and fNIRS.

The present study investigated the spatial ability of adolescent athletes with different sport expertise of axial rotation, providing the cognitive characteristics from both behavior and functional near-infrared spectroscopy (fNIRS) tests. 16 basketball and soccer players, 15 freestyle athletes and 15 runners were selected for spatial ability testing with a three-factor mixed experimental design of 3 (sport type: open high-spatial sport, closed high-spatial sport, closed low-spatial sport) × 2 (rotation angle: 45°, 90°) × 3 (rotation axis: horizontal, vertical, longitudinal). Repeated-measures ANOVA was performed to evaluate the behavioral and fNIRS data of the mental rotation test.

Axial rotation affects the cognitive characteristics of spatial ability.

Purpose: To test spatial ability in athletes with different axial rotation experience and analyze their behavioral data to explain the cognitive mechanisms of spatial ability in athletes.

Methods: Experiment 1: A total of 147 athletes were selected for the paper-and-pencil mental rotation test (MRT). The athletes were separated according to three sport types: open high-spatial (OH) sport, closed high-spatial (CH) sport, closed low-spatial (CL) sport.

Using Er/Cd-Codoped BiOBr Microspheres to Enhance Antibiotic Degradation under Visible Illumination: A Combined Experimental and DFT Investigation.

High levels of antibiotic accumulation and the difficulty of degradation can have serious consequences for the environment and, therefore, require urgent attention. To solve this problem, a synergistic Er and Cd ion-codoped BiOBr photocatalyst was proposed. The degradation rate of sulfamethoxazole (SMX) by Er/Cd-BiOBr was eight times higher than that of pure BiOBr, exceeding that of single Er-doped or Cd-doped BiOBr, which was attributed to the ability of Er/Cd-BiOBr to generate a variety of free radicals.

Topological superconductivity from unconventional band degeneracy with conventional pairing.

We present a new scheme for Majorana modes in systems with nonsymmorphic-symmetry-protected band degeneracy. We reveal that when the gapless fermionic excitations are encoded with conventional superconductivity and magnetism, which can be intrinsic or induced by proximity effect, topological superconductivity and Majorana modes can be obtained. We illustrate this outcome in a system which respects the space group P4/nmm and features a fourfold-degenerate fermionic mode at (π,  π) in the Brillouin zone.

Randomized trial of influence of vitamin D on the prevention and improvement of symptomatic COVID-19.

We aimed to investigate the preventive effect of vitamin D2 on COVID-19 and the improvement of symptoms after COVID-19 infection. The study recruited 228 health care workers who tested negative PCR or antigen for COVID-19. Subjects were randomly allocated to vitamin D2 or non-intervention at a ratio 1:1.

Directly visualizing nematic superconductivity driven by the pair density wave in NbSe.

Pair density wave (PDW) is a distinct superconducting state characterized by a periodic modulation of its order parameter in real space. Its intricate interplay with the charge density wave (CDW) state is a continuing topic of interest in condensed matter physics. While PDW states have been discovered in cuprates and other unconventional superconductors, the understanding of diverse PDWs and their interactions with different types of CDWs remains limited.

Visual observation of polystyrene nano-plastics in grape seedlings of Thompson Seedless and assessing their effects via transcriptomics and metabolomics.

Micro/nano-plastics (MNPs) are emerging non-point source pollutants that have garnered increasing attention owing to their threat to ecosystems. Studies on the effects of MNPs on horticultural crops are scarce. Specifically, whether MNPs can be absorbed and transported by grapevines have not been reported.

Synthesis and properties of bio-based semi-aromatic heat-resistant copolymer polyamide 5T-co-6T.

Herein, poly(pentanediamine terephthalamide) (PA5T) homopolymer was synthesized via a salt-forming reaction+solid state polycondensation method using bio-based 1,5-pentanediamine and terephthalic acid as the primary raw materials. To address the issue of its narrower processing window, poly(hexamethylene terephthalamide)(PA6T), which also cannot be melt processed due to the processing window is negative, was introduced into its molecular chain to synthesize poly (pentanediamine/hexanediamine terephthaloyl) (PA5T-co-6T) copolymers. The structures were investigated by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance carbon spectroscopy (C-NMR).

Tunable even- and odd-denominator fractional quantum Hall states in trilayer graphene.

Fractional quantum Hall (FQH) states are exotic quantum many-body phases whose elementary charged excitations are anyons obeying fractional braiding statistics. While most FQH states are believed to have Abelian anyons, the Moore-Read type states with even denominators - appearing at half filling of a Landau level (LL) - are predicted to possess non-Abelian excitations with appealing potential in topological quantum computation. These states, however, depend sensitively on the orbital contents of the single-particle LL wavefunctions and the LL mixing.
