Heart failure‐induced reprogramming of salt‐evoked neurovascular coupling in the rat hypothalamus

The Journal of Physiology, Volume 604, Issue 18, Page 7845-7868, 15 September 2026.
Abstract figure legend In sham rat, hypertonic saline induces activation of the AVP neurons, leading to dendritic AVP release and subsequent V1aR‐mediated PA vasoconstriction resulting in local tissue hypoxia in the SON. In heart failure rat, hypertonic saline similarly induces activation of the AVP neuron leading to dendritic AVP release.

Untangling Selberg from the Wilson spool: 1-loop determinants and trace formulae in (A)dS3

Journal of High Energy Physics
Leading quantum effects in perturbative quantum gravity are captured by functional determinants of kinetic operators. We study such 1-loop determinants in three-dimensional Euclidean (anti-) de Sitter gravity evaluated using two seemingly disparate tools,

Some Approaches to Solving the KP Equation: Different Representations and Various Types of Solutions

Axioms
We present different methods to construct solutions to the Kadomtsev–Petviashvili (KP) equation. In the first method, from the solutions to the NLS equation, we construct solutions to the KP equation in terms of Fredholm determinants. We deduce solutions

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 14122-14148, August 2026.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

A Hybrid Solid‐State Battery with a Panoramic‐Scale Stack of Bulk Electrodes and a Thin‐Film Electrolyte

Small, Volume 22, Issue 44, 7 August 2026.
A hybrid all‐solid‐state battery (ASSB) is implemented by integrating a thin‐film electrolyte on a bulk anode, and a thick cathode sheet. A densified anode substrate with suppressed porosity is prepared by cold pressing. Thin‐film electrolyte is fabricated onto the bulk substrate via co‐sputtering and infrared‐based rapid annealing.

Joint Identification of Groundwater Contamination Source and Heterogeneous Hydrogeological Parameters in LNAPL‐Contaminated Sites Based on Deep Convolutional Encoder‐Decoder Neural Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Accurate identification of nonaqueous phase liquid (NAPL) contamination sources is critical in pollution management. However, the joint inversion of source characteristics and heterogeneous hydrogeological parameters faces two major challenges.

A Riemann-Hilbert approach to Fredholm determinants of Hankel composition operators: Scalar-valued kernels

, 2023
We characterize Fredholm determinants of a class of Hankel composition operators via matrix-valued Riemann-Hilbert problems, for additive and multiplicative compositions.

Exploring superconformal Yang-Mills theories through matrix Bessel kernels

SciPost Physics
A broad class of observables in four-dimensional $\mathcal{N}=2$ and $\mathcal{N}=4$ superconformal Yang-Mills theories can be exactly computed in the planar limit for arbitrary 't Hooft coupling as Fredholm determinants of integrable Bessel operators ...

Bulk‐Surface Coupled PDE With an Open Boundary

Studies in Applied Mathematics, Volume 157, Issue 2, August 2026.
ABSTRACT We study a bulk‐surface coupled Laplace system involving an embedded open boundary. The problem is reformulated as an integro‐differential equation using boundary integral representations, for which we establish existence and uniqueness of the solution.
