Electrospun fibrous materials with fine fibers and small pores are fundamental for particulate matter (PM) filtration, addressing its harmful environmental and health impacts. However, the existing electrospun fibers are still limited to their sub-micron diameters and unstable surface electrostatic effect, leading to deteriorated filtration performance after prolonged storage or wetting. Herein, the study creates nanofibrous membranes with long-time stable electrostatics by electret-enhanced electrospinning.

Under salt stress, plasma membrane proteins regulate ion homeostasis and the balance between reactive oxygen species (ROS). In this study, we investigated the functions of two small membrane proteins-MsRCI2B (tailless) and MsRCI2E (tailed)-encoded by the RCI2 (Rare Cold Inducible 2) gene family in Medicago sativa (alfalfa). We identified the distinct subcellular localization and expression patterns of these proteins under salt stress.

Oxidative stress and neuronal apoptosis could be an important factor leading to post-hemorrhagic consequences after germinal matrix hemorrhage (GMH). Previously study have indicated that relaxin 2 receptor activation initiates anti-oxidative stress and anti-apoptosis in ischemia-reperfusion injury. However, whether relaxin 2 activation can attenuate oxidative stress and neuronal apoptosis after GMH remains unknown.

In this study, the interaction of crebanine, an isoquinoline alkaloid, with immunoglobulin G (IgG) was evaluated. Subsequently, the anticancer effects of crebanine in MCF-7 breast cancer cells were assessed. The results demonstrate that static quenching plays a key role in the fluorescence quenching of the IgG by crebanine, and some embedded hydrophobic patches of the IgG are exposed upon interaction with crebanine, while the characteristic β-sheet conformation of the IgG was almost preserved.

Increasing noise pollution has generated a tremendous threat to human health and incurred great economic losses. However, most existing noise-absorbing materials present a significant challenge in achieving lightweight, robust mechanical stability, and efficient low-frequency (<1000 Hz) noise reduction. Herein, we create highly compressible micro/nanofibrous sponges with thin-walled cavity structures for efficient noise reduction through electrospinning and dispersion casting.

The microstructure and residual mechanical properties of several groups of T92/Super304H dissimilar steel welded joints (hereinafter referred to as welded joints) in service for 70,000~85,000 h were analyzed. The results show that the early service history of the welded joint results in the polygonization of the martensite lath and the coarsening of the precipitated phase on the side of T92 steel. In the further creep process, the cavities nucleate along the precipitated phase interface and the triple junction grain boundary.

Named entity recognition (NER) is a crucial task in natural language processing, particularly challenging in the legal domain due to the intricate and lengthy nature of legal entities. Existing methods often struggle with accurately identifying entity boundaries and types in legal texts. To address these challenges, we propose a novel sequence-to-sequence framework designed specifically for the legal domain.

Dysregulated R-loop homeostasis leads to DNA replication stress and genomic instability, a major driver of cancer. However, the role of R-loops in melanoma development remains unclear. We established an R-loop scoring model based on a single-cell RNA sequencing dataset and evaluated the association between the R-loop score with the melanoma immune microenvironment and treatment response.

Anisotropic composite thermal control materials show efficient thermal management ability, which can not only improve the heat flow in the direction of high thermal conductivity and prevent local overheating, but also reduce the heat flow in the direction of the low thermal conductivity and improve thermal insulation. In this paper, the anisotropic microstructure of natural wood ( poplar) was used as a reference template. The filling of the SiO aerogel into the multi-layer pore structure and microtubule structure originally occupied by lignin was controlled by the process of the axial self-adsorption, limited sol-gel and natural drying.

High-entropy oxide (HEO) has emerged as a promising anode material for high-energy lithium-ion batteries (LIBs) due to its high theoretical specific capacity. However, the further application of HEO is restricted by its complicated interface problems and inevitable expansion effect. In this work, a simple approach to coat spinel HEO (FeCoNiCrMn)O with a hybrid layer of lithium titanate (LTO) and carbon is presented.

  • Graph Neural Networks (GNNs) effectively learn from graph-structured data but can unintentionally lead to discrimination against certain groups due to correlations with sensitive attributes.
  • To address this issue, the Fair Disentangled Graph Neural Network (FDGNN) framework is introduced, which focuses on creating fair node representations by augmenting data diversity and addressing sensitive value distributions.
  • Extensive experiments show that FDGNN outperforms traditional methods in fairness while demonstrating the effectiveness of disentanglement in learning unbiased representations.
