Shannon Entropy of Gray Matter Eigenmodes: A Novel Biomarker for Alzheimer's Disease and Heterogeneous MCI Trajectories

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Entropy derived from gray matter eigenmodes captures cortical disorganization in Alzheimer's disease. Using multimodal MRI and amyloid‐PET data, this novel structure–function coupling biomarker enables accurate classification of clinical stages, predicts Aβ burden, and stratifies mild cognitive impairment subtypes.

Stabilizing Anion–Anion Aggregates via Dihydrogen Bonds in Non‐Classical Inorganic Molecules

open access: yesAggregate, Volume 7, Issue 1, January 2026.
Despite Coulomb's law, the anionic [o‐FESAN]− cluster forms stable anti‐electrostatic aggregates via short dihydrogen bonds. Experimental (nuclear magnetic resonance, dynamic light scattering, and X‐ray diffraction) and theoretical (density functional theory) studies reveal that C–H···H–B interactions overcome long‐range repulsion, enabling cluster ...

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Influence of Blood Rheology on Hemodialysis Efficiency via Computational Simulation

open access: yesChemical Engineering &Technology, Volume 49, Issue 1, January 2026.
This study presents a CFD framework for hemodialysis that explicitly incorporates cholesterol‐dependent non‐Newtonian blood rheology. By coupling mass transport with the mHAWB model, the work quantifies how rheology alters creatinine removal and optimal operating conditions. ABSTRACT This work presents a computational study of hemodialysis in cocurrent

Machine Learning Unlocks New Directions in Halide Perovskite Research

open access: yesChemElectroChem, Volume 13, Issue 1, January 2026.
GA: This frontispiece visualizes the role of machine learning (ML) in advancing halide perovskite research. It highlights how ML enables the prediction of material properties, guides compositional design, and supports the development of stable, high‐performance perovskite devices for optoelectronic applications, providing new strategies to overcome ...
