Existence of Solution for Two Classes of Quasilinear Systems Defined on a Nonreflexive Orlicz–Sobolev Spaces

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13324-13360, August 2026.
ABSTRACT This paper proves the existence of nontrivial solution for two classes of quasilinear systems of the type −ΔΦ1u=Fu(x,u,v)+λRu(x,u,v)inΩ−ΔΦ2v=−Fv(x,u,v)−λRv(x,u,v)inΩu=v=0on∂Ω$$ \left\{\begin{array}{l}\hfill -{\Delta}_{\Phi_1}u={F}_u\left(x,u,v\right)+\lambda {R}_u\left(x,u,v\right)\kern0.1832424242424242em \mathrm{in}\kern0.3em \Omega ...

Persistent sheaf Laplacian analysis of protein stability and solubility changes upon mutation

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Genetic mutations frequently disrupt protein structure, stability, and solubility, acting as primary drivers for a wide spectrum of diseases. Despite the critical importance of these molecular alterations, existing computational models often lack interpretability and fail to integrate essential physicochemical interactions.

Ultrafast Nonadiabatic Dynamics of Tetraphenyl‐substituted Nitrogen‐Based Heterocycles

Small Structures, Volume 7, Issue 8, August 2026.
Two molecules share four phenyl substituents but differ in their core (pyrazine vs. pyrrole), leading to very different emission behavior. One becomes highly emissive upon aggregation, while the other emits similarly in solution and solid states.

Optimization Algorithm for Determining the Source Surface Radius Based on Parker Solar Probe In Situ Measurements From Encounters 1 to 19

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The Potential Field Source Surface (PFSS) extrapolation is a method for estimating the large scale coronal magnetic field from photospheric magnetograms. The source surface serves as the outer boundary of its solution domain, and is typically a spherical surface.

PETIMOT: a novel framework for inferring protein motions from sparse data using SE(3)‐equivariant graph neural networks

Acta Crystallographica Section D, Volume 82, Issue 8, Page 862-885, August 2026.
We present a new formulation for protein flexibility and learn protein motions from sparse experimental data.Proteins move and deform to ensure their biological functions. Despite significant progress in protein structure prediction, approximating conformational ensembles under physiological conditions remains a fundamental open problem.

Enhancing Classification Performance on Imbalanced Datasets Through Complexity‐Guided Oversampling With SMOTE

Expert Systems, Volume 43, Issue 8, August 2026.
ABSTRACT Improving classification performance on imbalanced datasets remains a challenging problem in machine learning. Synthetic oversampling techniques such as SMOTE are widely used to address class imbalance; however, their random interpolation strategy often ignores structural data properties, which may affect classifier generalisation.

Machine Learning of Personal Repertoires From Public T Cell Receptors

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT The T‐cell receptor (TCR) repertoire records an individual's immunological history, but most unique CDR3 sequences in any one person are private and uninformative about anyone else. A small subset, however, recurs predictably across unrelated donors.

Inference on the Attractor Space via Functional Approximation

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 643-657, August 2026.
ABSTRACT This paper discusses semiparametric inference on hypotheses on the cointegration and the attractor spaces for I(1) linear processes with moderately large cross‐sectional dimension. The approach is based on sample canonical correlations and functional approximation of Brownian motions, and it can be applied both to the whole system and or to ...
