Cardiometabolic Index as a Mediator in the Association Between Estimated Glucose Disposal Rate and Depressive Symptoms: A Population‐Based Study

open access: yesBrain and Behavior, Volume 16, Issue 2, February 2026.
This cross‐sectional study included individuals who took part in the NHANES from 2003 to 2018. Our results demonstrated that higher eGDR correlates with lower likelihood of depressive symptoms, with CMI acting as a mediator. Reducing insulin resistance and monitoring CMI could help decrease the occurrence of depression.

The Numerical Solution of Volterra Integral Equations

open access: yesAxioms
Recently we studied a collocation–quadrature method in weighted L2 spaces as well as in the space of continuous functions for a Volterra-like integral equation of the form u(x)−∫αx1h(x−αy)u(y)dy=f(x ...

The influence of multiple stressors on the spatial distribution of corals

open access: yesPeople and Nature, Volume 8, Issue 2, Page 342-358, February 2026.
Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...

Mathematical model of non-stationary temperature distribution in the metal body produced by induction heating process

open access: yesEPJ Web of Conferences, 2016
An induction heating problem can be described by a parabolic differential equation. For this equation, specific Joule looses must be computed. It can be done by solving the Fredholm Integral Equation of the second kind for the eddy current of density ...

Multi-view Metric Learning in Vector-valued Kernel Spaces

open access: yes, 2018
We consider the problem of metric learning for multi-view data and present a novel method for learning within-view as well as between-view metrics in vector-valued kernel spaces, as a way to capture multi-modal structure of the data.

A symplectic explicit trigonometrically-fitted Runge-Kutta-Nyström method for the numerical solution of periodic problems [PDF]

open access: yes, 2016
In this paper, symplectic third-order three-stage explicit trigonometrically-fitted Runge-Kutta-Nyström (RKN) method for the numerical solution of second order initial value problems with periodic solutions is derived.

Online Learning in Idealized Ocean Gyres

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Ocean turbulence parameterization has principally been based on process‐based approaches, seeking to embed physical principles so that coarser resolution calculations can capture the net influence of smaller scale unresolved processes. More recently there has been an increasing focus on the application of data‐driven approaches to this problem.

Efficient Nyström-Based Unitary Single-Tone 2D DOA Estimation for URA Signals

open access: yesMathematics
We propose an efficient Nyström-based unitary subspace method for low-complexity two-dimensional (2D) direction-of-arrival (DOA) estimation in uniform rectangular array (URA) signal processing systems.

Neural Operators for Continuous Bias Correction of Water Level Forecast Guidance

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract The National Oceanic and Atmospheric Administration's (NOAA) Global Two‐Dimensional Surge and Tide Operational Forecast System (STOFS‐2D‐Global) provides global operational tidal, subtidal, and total water level forecast guidance with a 7.5‐day horizon.
