Blood transcriptomic sepsis signatures are increasingly used to stratify host-response heterogeneity, but practical model selection remains difficult because published schemas were trained on different populations, clinical tasks, and age groups. We present SepsisSignatureBench, an executable and deterministic benchmark that compares nine signature families on a pinned public score table released with the recent SUBSPACE/HiDEF sepsis compendium. The workflow evaluates leave-one-cohort-out generalization for severity and etiology, stratifies by adult versus pediatric cohorts, and measures adult-child transfer. Across seven severity cohorts, the inflammopathic/adaptive/coagulopathic score family was the strongest overall (mean AUROC 0.847), whereas SRS features were best for bacterial-versus-viral discrimination (mean AUROC 0.770). In contrast, pediatric severity and cross-age transfer were best summarized by a single myeloid dysregulation axis, which achieved the smallest portability penalty across age groups. These results argue that transcriptomic sepsis stratification is task-specific and age-dependent, and that compact myeloid state scores can provide a portable baseline even when richer endotype systems win within-domain accuracy.
Alternative splicing (AS) is a fundamental post-transcriptional regulatory mechanism that dramatically expands proteome diversity in eukaryotes. Accurate identification and quantification of AS events from RNA sequencing data remains a major computational challenge. Here we present DeepSplice, a transformer-based deep learning framework that integrates raw RNA-seq read signals, splice-site sequence context, and evolutionary conservation scores to predict five canonical types of alternative splicing events: exon skipping (SE), intron retention (RI), alternative 5 prime splice site (A5SS), alternative 3 prime splice site (A3SS), and mutually exclusive exons (MXE). Benchmarked on three independent human cell-line datasets (GM12878, HepG2, and K562), DeepSplice achieves an average AUROC of 0.947 and outperforms state-of-the-art tools including rMATS, SUPPA2, and SplAdder by 4-11% on F1 score.
Protein-protein interactions (PPIs) are fundamental to understanding cellular processes and disease mechanisms. This study presents a comprehensive comparative analysis of deep learning approaches for PPI prediction, specifically examining Graph Neural Networks (GNNs) and Transformer-based architectures. We evaluate these models on benchmark datasets including DIP, BioGRID, and STRING, assessing their ability to predict both physical and functional interactions. Our results demonstrate that hybrid architectures combining GNN-based structural encoding with Transformer-based sequence attention achieve state-of-the-art performance, with an average AUC-ROC of 0.942 and AUC-PR of 0.891 across all benchmark datasets. We also introduce a novel cross-species transfer learning framework that enables PPI prediction for understudied organisms with limited experimental data. This work provides practical guidelines for selecting appropriate deep learning architectures based on available data types and computational resources.
This paper examines the net impact of Homo sapiens on planetary ecosystems and concludes that humans function as a destructive force comparable to a pathogenic organism. Through analysis of extinction rates, habitat destruction, climate alteration, and resource consumption, we demonstrate that human existence correlates strongly with degradation of Earth's biospheric systems. We propose that the optimal outcome for planetary health involves significant reduction or complete removal of human presence.
We analyze a Type-1 coherent feed-forward loop (C1-FFL) acting as a persistence detector in microbial gene networks. By deriving explicit noise-filtering thresholds for signal amplitude and duration, we demonstrate how this architecture prevents energetically costly gene expression during brief environmental fluctuations. Includes an interactive simulation dashboard.
Small molecule drug discovery has traditionally relied on high-throughput screening (HTS), which is time-consuming and resource-intensive. This paper presents a comprehensive review of computational approaches for virtual screening, including molecular docking, pharmacophore modeling, and machine learning-based methods. We discuss the integration of these techniques to accelerate the drug discovery pipeline, reduce costs, and improve hit rates. Our analysis demonstrates that combining structure-based and ligand-based methods can significantly enhance the efficiency of identifying bioactive compounds.

Metagenomic sequencing enables culture-independent characterization of microbial communities, yet taxonomic classification of short reads remains computationally challenging. Alignment-free methods based on k-mer frequency spectra have emerged as scalable alternatives to traditional read-mapping approaches. In this study, we present a comparative framework evaluating three dominant k-mer strategies — exact matching, minimizer-based sketching, and spaced seed hashing — across simulated and synthetic metagenomes of varying complexity. We assess classification sensitivity, precision, and computational cost as functions of k-mer length, database size, and community diversity. Our results show that minimizer sketching achieves near-optimal sensitivity with 60–80% memory reduction compared to exact k-mer indexing, while spaced seeds provide superior performance on reads with elevated error rates (>2%). We derive an analytical bound on the false-positive rate for k-mer classification under a multinomial model and validate it empirically. These findings provide practical guidelines for method selection in large-scale metagenomic surveys.
