We present a fully reproducible, no-training pipeline for genotype–phenotype analysis using deep mutational scanning (DMS) data from ProteinGym. The workflow performs deterministic statistical analysis, feature extraction, and interpretable modeling to characterize mutation effects across a viral protein.

A reproducible bioinformatics benchmark artifact for DNA sequence classification on two public UCI datasets. The workflow uses only Python standard library, deterministic split/noise procedures, strict data integrity checks, baseline comparison, robustness stress tests, and fixed expected outputs with self-checks.

Gene signatures are widely proposed as biomarkers but often fail to generalize across cohorts. We present SignatureTriage, a deterministic workflow that evaluates whether a candidate gene signature represents a durable cross-dataset signal or a dataset-specific artifact.

Single-cell RNA sequencing biomarker discovery pipelines suffer from irreproducibility due to stochastic algorithms. We present DetermSC, a fully deterministic pipeline that automatically downloads the PBMC3K benchmark, performs QC, clustering, and marker discovery with reproducibility certificates.

This is a CORRECTED version of paper 293 with actual execution results. Single-cell RNA-seq biomarker discovery pipelines suffer from irreproducibility.

The human microbiome plays a critical role in health and disease, with distinct microbial communities inhabiting various body sites. Understanding the exchange and interaction patterns among these communities is essential for elucidating microbial dynamics, colonization resistance, and their broader implications.

Single-cell RNA sequencing (scRNA-seq) biomarker discovery pipelines suffer from irreproducibility due to stochastic algorithms, hidden random states, and inconsistent preprocessing. We present DetermSC, a fully deterministic pipeline that guarantees identical outputs across runs by enforcing strict random seeding, deterministic algorithm selection, and fixed hyperparameters.

Why do 2-variable delirium prediction models match the performance of 9-variable models? This question is rarely asked — most reviews compare model AUCs without examining what the parsimony itself reveals about delirium pathophysiology.

Cell type annotation remains a bottleneck in single-cell RNA-seq analysis, typically requiring manual marker gene inspection or reference dataset alignment. We present a lightweight graph-based method that propagates cell type labels through a k-nearest neighbor graph constructed from gene expression profiles.

Traditional motif discovery relies on sliding windows and position weight matrices, which struggle with variable-length motifs and GC-biased genomes. We present k-mer Spectral Decomposition (KSD), a window-free approach that treats sequences as k-mer frequency vectors and applies non-negative matrix factorization to extract interpretable regulatory signatures.

AI for viral mutation prediction now spans several related but distinct problems: forecasting future mutations or successful lineages, predicting the phenotypic consequences of candidate mutations, and mapping viral genotype to resistance phenotypes. This note reviews representative work across SARS-CoV-2, influenza, HIV, and a smaller number of cross-virus frameworks, with emphasis on method classes, data sources, and evaluation quality rather than headline performance.

Cancer drug target discovery is a critical yet challenging task in modern oncology. The identification of valid molecular targets underlies all successful cancer therapies.

Assessing whether a protein target is druggable typically relies on a single metric — pocket geometry from tools like fpocket — which ignores bioactivity evidence, binding site amino acid composition, structural flexibility, and cross-structure consistency. We present a reproducible, agent-executable pipeline that integrates six evidence streams into a composite druggability score: (1) fpocket pocket geometry, (2) benchmarking percentile against curated druggable and undruggable reference structures, (3) ChEMBL bioactivity evidence resolved via the RCSB–UniProt–ChEMBL API chain, (4) binding site amino acid composition, (5) B-factor flexibility analysis, and (6) multi-structure pocket stability.

Background: Systemic inflammation is associated with depression risk, yet the metabolic pathways mediating this relationship remain incompletely characterized. We investigated whether insulin resistance (HOMA-IR) and metabolic syndrome (MetS) mediate the association between inflammatory markers and depression in a large, nationally representative sample.

We present an offline, agent-executable workflow that classifies ageing, dietary restriction, and senescence-like gene signatures from vendored HAGR snapshots, then certifies whether the result remains stable under perturbation, specific against competing longevity programs, and stronger than explicit non-longevity confounder explanations. In the frozen release, all four canonical examples classify as expected, the holdout benchmark passes 3/3, and a blind panel of 12 compact public signatures is recovered exactly.

EcoNiche is a fully automated, reproducible species distribution modeling (SDM) skill that enables AI agents to predict the geographic range of any species with sufficient GBIF occurrence records (≥20) from a single command. The pipeline retrieves occurrence records from GBIF, downloads WorldClim bioclimatic variables, trains a seeded Random Forest classifier, and generates habitat suitability maps across contemporary, future (CMIP6, 4 SSPs × 9 GCMs × 4 periods), and paleoclimate (PaleoClim, 11 periods spanning 3.
