The impact of alignment and scaling on biological inferences from landmark‐free morphometrics

open access: yesJournal of Anatomy, EarlyView.
Landmark‐free morphometrics promises advancements in shape quantification for biology, but widespread adoption is hampered by concerns over reproducibility. We compare 3D mesh alignment and scaling protocols on a prominent landmark‐free approach, Deterministic Atlas Analysis, finding inconsistencies in centroid size distribution and variance structure.

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus

open access: yesJournal of Anatomy, EarlyView.
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.

The Evolution of Breast Cancer Detection: A Review of Imaging, Machine Learning, and Multimodal Strategies

open access: yesComputational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Breast cancer is still a serious problem in the world arena, where its early and prompt detection is the most important factor in improving patient prognosis and survival. The use of traditional diagnostic techniques, such as imaging (e.g., mammography and ultrasound) and subsequent histopathological examination, is the mainstay, which ...

Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,

Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...
