Background: Clustering analysis is fundamental in single-cell RNA sequencing (scRNA-seq) data analysis for elucidating cellular heterogeneity and diversity. Recent graph-based scRNA-seq clustering methods, particularly graph neural networks (GNNs), have significantly improved in tackling the challenges of high-dimension, high-sparsity, and frequent dropout events that lead to ambiguous cell population boundaries. However, one major challenge for GNN-based methods is their reliance on hard graph constructions derived from similarity matrices.

Lithium-ion (Li-ion) solid-state batteries (SSBs) are highly regarded for their exceptional energy density and prolonged operational lifespan. However, concerns regarding their sustainability have arisen due to the uneven global distribution of Li resources and Li's relatively low abundance in the Earth's crust. Consequently, significant interest has shifted toward developing alternative SSBs, such as sodium (Na), magnesium (Mg) and Aluminum (Al)-ion batteries.

FemXpress: Systematic Analysis of X Chromosome Inactivation Heterogeneity in Female Single-Cell RNA-Seq Samples.

Adv Sci (Weinh)

June 2025

State Key Laboratory of Stem Cell and Reproductive Biology, Institute of Zoology, Chinese Academy of Sciences, Beijing, 100101, China.

X chromosome inactivation (XCI) is crucial for balancing X-linked gene dosage in female cells by randomly silencing one X chromosome during early embryogenesis. However, accurately classifying cells based on the parental origin of the inactivated X chromosome in single-cell samples remains challenging. Here we present FemXpress, a computational tool leveraging X-linked single nucleotide polymorphisms (SNPs) to group cells based on the origin of the inactivated X chromosome in female single-cell RNA sequencing (scRNA-Seq) data.

Semiflexible polymer folding has been employed by nature for protein folding and by researchers for designing smart materials and nanomachines. Hence, it is of great importance to understand and control semiflexible polymer folding. Here, we find that the range of intermonomer attraction, or the width of attraction (), can significantly control the structural phase diagram of a semiflexible polymer through entropic effects.

April 2025

The State Key Laboratory of Chemo/Biosensing and Chemometrics, Hunan University, Changsha 410082, China.

Novel drug discovery and repositioning remain critical challenges in biomedical research, requiring accurate prediction of drug-target interactions (DTIs). We propose the CPDP framework, which builds upon existing biomedical representation models and integrates contrastive learning with multi-dimensional representations of proteins and drugs to predict DTIs. By aligning the representation space, CPDP enables GNN-based methods to achieve zero-shot learning capabilities, allowing for accurate predictions of unseen drug data.

The purpose of feature selection in protein sequence recognition problems is to select the optimal feature set and use it as training input for classifiers and discover key sequence features of specific proteins. In the feature selection process, relevant features associated with the target task will be retained, and irrelevant and redundant features will be removed. Therefore, in an ideal state, a feature combination with smaller feature dimensions and higher performance indicators is desired.
