HierAnom‐Path: Zero‐Shot Rare Cancer Detection in Histopathology via Hierarchical Foundation Model Adaptation

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Rare cancers collectively represent 20%–25% of all malignancies yet yield fewer than 50 annotated whole‐slide images (WSIs) per subtype in publicly available archives, rendering supervised deep learning inapplicable. We present HierAnom‐Path, to the best of our knowledge, the first framework for zero‐shot rare cancer anomaly detection in ...

Teleport‐stabilised quantum‐walk transport for robust neoantigen ranking in near‐tie regimes: A reproducible colorectal benchmark

Clinical and Translational Discovery, Volume 6, Issue 6, December 2026.
Teleport‐stabilised quantum‐walk transport for robust neoantigen ranking in near‐tie regimes. The analysis proceeds from patient‐conditioned candidate definition to weighted evidence‐graph construction, quotient‐basin compression, continuous‐time quantum‐walk (CTQW)/discrete‐time quantum walk (DTQW) transport, teleport‐consensus stabilisation, ABHA ...

Analysis of SHA-512/224 and SHA-512/256 [PDF]

In 2012, NIST standardized SHA-512/224 and SHA-512/256, two truncated variants of SHA-512, in FIPS 180-4. These two hash functions are faster than SHA-224 and SHA-256 on 64-bit platforms, while maintaining the same hash size and claimed security level ...

TAMAVAQ/Q‐TAMAVAQ: Fubini–study CTQW graph transport and constrained margin‐based ranking for neoantigen candidate prioritization in lower‐grade glioma and glioblastoma

Clinical and Translational Discovery, Volume 6, Issue 6, December 2026.
Abstract Background Personalized neoantigen vaccine design for glioma requires the integration of mutation‐derived peptide evidence, molecular properties, HLA coverage and finite manufacturing capacity. TAMAVAQ/Q‐TAMAVAQ combines quantum‐geometric descriptor representation with graph transport and auditable peptide‐panel assembly.

Comparative Analysis of MD5 and SHA-256 Hash Algorithms for Fingerprint File Integrity Verification

Journal of Applied Informatics and Computing
Fingerprint file integrity verification in driver license systems requires reliable cryptographic hash algorithms. MD5, currently widely deployed, has been deprecated by NIST (2008) due to demonstrated collision vulnerabilities, while SHA-256 offers ...

Ventricular and Choroid Plexus Morphological Alterations and Their Associations With Peripheral Biomarkers in Behavioral Variant Frontotemporal Dementia

Brain and Behavior, Volume 16, Issue 11, November 2026.
ABSTRACT Background Frontotemporal dementia (FTD) is a neurodegenerative disorder and a major cause of early‐onset dementia. Alterations in ventricular and choroid plexus volumes have been reported in several neurodegenerative diseases. The morphological alterations of the ventricular system and choroid plexus in behavioral variant frontotemporal ...

Preimage Attacks on 41-Step SHA-256 and 46-Step SHA-512 [PDF]

, 2009
In this paper, we propose preimage attacks on 41-step SHA-256 and 46-step SHA-512, which drastically increase the number of attacked steps compared to the best previous preimage attack working for only 24 steps. The time complexity for 41-step SHA-256 is

A Chaos‐Driven Image Encryption Method With Möbius Transformations and Finite‐Ring Diffusion

Engineering Reports, Volume 8, Issue 11, November 2026.
This paper presents a lightweight yet highly secure image encryption framework integrating chaotic dynamics, HKDF‐S3 key expansion, and Möbius‐Affine transformations. The proposed scheme achieves strong confusion and diffusion with minimal computational cost, demonstrating high resistance to differential and chosen‐plaintext attacks through dynamic key
