Computer vision‐based recognition and distinction of Arabidopsis thaliana ecotypes using supervised deep learning models

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Image‐based plant phenotyping has diverse applications, ranging from providing quantitative traits for genetic breeding to enhancing management practices for indoor and outdoor production systems. Misidentification of cell lines or ecotypes/varieties is a major problem across all biological research disciplines.

Graph transformer with disease subgraph positional encoding for improved comorbidity prediction

Quantitative Biology, Volume 13, Issue 4, December 2025.
Abstract Comorbidity, the co‐occurrence of multiple medical conditions in a single patient, profoundly impacts disease management and outcomes. Understanding these complex interconnections is crucial, especially in contexts where comorbidities exacerbate outcomes.

Spatial transcriptomics iterative hierarchical clustering (stIHC): A novel method for identifying spatial gene co‐expression modules

Quantitative Biology, Volume 13, Issue 4, December 2025.
Abstract Recent advancements in spatial transcriptomics (ST) technologies allow researchers to simultaneously measure RNA expression levels for hundreds to thousands of genes while preserving spatial information within tissues, providing critical insights into spatial gene expression patterns, tissue organization, and gene functionality.

Entropy in Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, Volume 78, Issue 10, Page 2001-2118, October 2025.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

A Nordhaus–Gaddum Problem for the Spectral Gap of a Graph

Journal of Graph Theory, Volume 110, Issue 2, Page 132-144, October 2025.
ABSTRACT Let G be a graph on n vertices, with complement G ¯. The spectral gap of the transition probability matrix of a random walk on G is used to estimate how fast the random walk becomes stationary. We prove that the larger spectral gap of G and G ¯ is Ω ( 1 ∕ n ).

A note on the magnetic Steklov operator on functions

Mathematika, Volume 71, Issue 4, October 2025.
Abstract We consider the magnetic Steklov eigenvalue problem on compact Riemannian manifolds with boundary for generic magnetic potentials and establish various results concerning the spectrum. We provide equivalent characterizations of magnetic Steklov operators which are unitarily equivalent to the classical Steklov operator and study bounds for the ...

Generalized φ‐Pullback Attractors in Time‐Dependent Spaces: Application to a Nonautonomous Wave Equation With Time‐Dependent Propagation Velocity

Mathematical Methods in the Applied Sciences, Volume 48, Issue 14, Page 13456-13474, 30 September 2025.
ABSTRACT We present sufficient conditions to obtain a generalized (φ,D)$$ \left(\varphi, \mathfrak{D}\right) $$‐pullback attractor for evolution processes on time‐dependent phase spaces, where φ$$ \varphi $$ is a given decay function and D$$ \mathfrak{D} $$ is a given universe.

Development and clinical implementation of an MRI‐only planning workflow featuring deep learning‐based synthetic CT for prostate cancer external beam radiotherapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Background In external beam radiation therapy (EBRT) for prostate cancer, both MRI and CT are typically used—CT provides electron density for dose calculation and visualization of bony anatomy and fiducial markers, while MRI offers superior soft tissue contrast.
