Fractional Variational Graph Autoencoders for Enhancing Non-Local Representation Learning on Graphs

Information
While Graph Autoencoders (GAEs) have become a standard for unsupervised representation learning, their reliance on integer-order convolutions inherently restricts information propagation to immediate local neighborhoods.

The Hunt for HLA‐DQ Allogeneic Eplets Is Not Over: Four New Ones, Including a Cross‐Chain Eplet

HLA, Volume 106, Issue 3, September 2025.
ABSTRACT The target of an anti‐HLA antibody is an epitope on the surface of the antigen, and in particular the polymorphic eplet of its core, which contains one or a few polymorphic residues accessible to the molecule surface. The HLA Eplet Registry database references more than 550 HLA eplets thus deduced from AA sequence alignments.

THeGCN: Temporal Heterophilic Graph Convolutional Network

CoRR
Graph Neural Networks (GNNs) have exhibited remarkable efficacy in diverse graph learning tasks, particularly on static homophilic graphs. Recent attention has pivoted towards more intricate structures, encompassing (1) static heterophilic graphs encountering the edge heterophily issue in the spatial domain and (2) event-based continuous graphs in the ...

EGCG Alleviates H2O2‐Induced Inflammatory Injury and Apoptosis in Bovine Mammary Epithelial Cells Through Nrf2 Pathway Activation and p38MAPK Pathway Inhibition

Food Science &Nutrition, Volume 13, Issue 3, March 2025.
The present study sought to investigate the protective effects of epigallocatechin‐3‐gallate (EGCG) on hydrogen peroxide‐induced oxidative stress, inflammation, and apoptosis, and related mechanisms. The test showed that EGCG could improve the antioxidant function of bovine mammary epithelial cells by activating the Nrf2 and inhibiting the p38 mitogen ...

Beyond Homophily: Community Search on Heterophilic Graphs

CoRR
Community search aims to identify a refined set of nodes that are most relevant to a given query, supporting tasks ranging from fraud detection to recommendation. Unlike homophilic graphs, many real-world networks are heterophilic, where edges predominantly connect dissimilar nodes.

Data‐efficient graph learning: Problems, progress, and prospects

AI Magazine, Volume 45, Issue 4, Page 549-560, Winter 2024.
Abstract Graph‐structured data, ranging from social networks to financial transaction networks, from citation networks to gene regulatory networks, have been widely used for modeling a myriad of real‐world systems. As a prevailing model architecture to model graph‐structured data, graph neural networks (GNNs) have drawn much attention in both academic ...

Evolution of CEACAM pathogen decoy receptors in primates

European Journal of Clinical Investigation, Volume 54, Issue S2, December 2024.
In humans, pathogen binding to the inhibitory receptor CEACAM1 on leukocytes allows immune escape while engagement of the neutrophil‐specific endocytic CEACAM3 decoy receptor enables destruction. Easily shed GPI‐linked epithelial CEACAM5 and CEACAM6 might act as soluble or extracellular vesicle‐bound decoy receptors.

Opposing positions, dividing interactions, and hostile affect: A systematic review and conceptualization of “online climate change polarization”

WIREs Climate Change, Volume 15, Issue 6, November/December 2024.
Six dimensions of online climate change polarization. Abstract Online climate change polarization has increasingly received academic interest over time. Online media facilitate and accelerate processes of climate change polarization. Yet, throughout the years, online climate change polarization became a fuzzy concept, holding different meanings in ...
