A Theory of the Boundaries of Banks With Implications for Financial Integration and Regulation

Financial Management, EarlyView.
ABSTRACT We offer a theory of the “boundary of the firm” that is tailored to banks, recognizing the relevance of deposit financing and interbank lending as a substitute for integration. It is based on a single inefficiency that has been at the core of banking theory: risk‐shifting incentives in the interest of bank shareholders.

Early signals of water limitations begin at the root–soil interface: linking rhizosphere drying to water uptake decline

New Phytologist, EarlyView.
Summary Understanding when and where drought stress originates in the soil–plant continuum is essential for predicting plant responses to climate change. While stomatal closure is a well‐known reaction to declining soil moisture, the precise hydraulic trigger remains unresolved.

Diffusion model‐regularized implicit neural representation for computed tomography metal artifact reduction

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract Computed tomography (CT) images are often severely corrupted by artifacts in the presence of metals. Existing supervised metal artifact reduction (MAR) approaches suffer from performance instability on known data due to their reliance on limited paired metal‐clean data, which limits their clinical applicability. Moreover, existing unsupervised

Bitsadze-Samarsky type problems with double involution

Boundary Value Problems
In this paper, the solvability of a new class of nonlocal boundary value problems for the Poisson equation is studied. Nonlocal conditions are specified in the form of a connection between the values of the unknown function at different points of the ...

Expletive Constructions and Agreement in Labeling Theory

Studia Linguistica, Volume 80, Issue 1, April 2026.
ABSTRACT In this paper, I explain how agreement occurs in English expletive constructions, in accord with recent work in the Minimalist Program. I develop a proposal that relies on feature unification and probe‐goal agreement, as well as the notion that internal merge of arguments generally applies freely.

Tests of Exponential Stabilization Through Floquet Theory and Act‐And‐Wait Control

Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 3303-3316, 15 March 2026.
ABSTRACT In this paper, we propose tests of exponential stability based on a version of the Floquet theory for delay differential equations of the first order. Our approach allows researchers to preserve the order of equation and to use the classical methods of the Floquet theory for ordinary differential equations.

Ghost effect from Boltzmann theory

Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 558-675, March 2026.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

A combined problem with local and nonlocal conditions for a class of mixed-type equations

Қарағанды университетінің хабаршысы. Математика сериясы
This paper investigates the issues of existence and uniqueness of a solution to a combined boundary value problem with local and nonlocal conditions for a specific class of mixed elliptic-hyperbolic-type equations with singular coefficients.

Denoising Low‐Power CEST Imaging Using a Deep Learning Approach With a Dual‐Power Feature Preparation Strategy

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1410-1428, March 2026.
ABSTRACT Purpose: Low‐power (LP) chemical exchange saturation transfer (CEST) Z‐spectra have significantly reduced confounding effects and enhanced peak resolvability, thereby improving the observation and quantification of various CEST effects. However, LP Z‐spectra suffer greatly from reduced contrast‐to‐noise ratio (CNR).

Peridynamics with a Cube‐Shaped Neighborhood

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT This paper investigates the effects of cube‐shaped neighborhoods in peridynamic theory as an alternative to the traditional spherical neighborhoods. We examine how different neighborhood geometries influence the behavior of various peridynamic formulations, including bond‐based models, state‐based formulations, and correspondence methods.
