Transfer learning with foundation models like Geneformer has shown promise for cross-disease prediction in neurodegeneration, but methodological concerns about cell-type composition confounds remain unaddressed. We conducted cell-type stratified experiments across Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), fine-tuning Geneformer within four homogeneous cell populations.

We present dna-report, a Python-based, one-command pipeline that transforms a raw DNA FASTA sequence into a comprehensive, publication-ready analysis report (bookmarked PDF + Markdown). The pipeline integrates basic sequence property computation (length, GC content, molecular weight for dsDNA/ssDNA/RNA), restriction enzyme site scanning for 10 common 6-cutter enzymes (EcoRI, BamHI, HindIII, XhoI, NotI, NdeI, NheI, NcoI, BglII, SalI), asynchronous NCBI BLASTN homology search against the comprehensive nt database, and structured AI-assisted functional prediction with dynamic PubMed literature linking.

Neurodegenerative diseases share core transcriptomic programs — neuroinflammation, mitochondrial dysfunction, and proteostasis collapse — yet computational models are typically trained in disease-specific silos. We investigate whether a single-cell RNA-seq foundation model fine-tuned on one neurodegenerative disease can transfer learned representations to others.

Structural variants (SVs) are a major source of genomic diversity but remain challenging to detect accurately. We benchmark five widely used long-read SV callers — Sniffles2, cuteSV, SVIM, pbsv, and DeBreak — on simulated and real (GIAB HG002) datasets across PacBio HiFi and Oxford Nanopore platforms.

Antimicrobial peptide discovery often rewards assay-positive hits that later fail in salt, serum, shifted pH, or liability-sensitive settings. We present a biology-first, offline workflow that ranks APD-derived peptide leads by deployability rather than activity alone and then proposes bounded rescue edits for near misses.

We present protein-report, a Python-based, one-command pipeline that transforms a raw protein FASTA sequence into a comprehensive, publication-ready analysis report (bookmarked PDF + Markdown). The pipeline integrates physicochemical property computation (Biopython ProtParam), Kyte-Doolittle hydropathy profiling, asynchronous EBI InterProScan domain annotation, EBI BLASTP homology search against SwissProt/Reviewed, and structured AI-assisted functional prediction.

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.

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.

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.

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.
