Multiscale mechanistic modelling of heterogeneity in cardiac sub‐cellular calcium handling accounting for variable t‐system density

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Illustration of spatial calcium dynamics (left panels) and the state cycle approximation (middle panel) that enables reduced simulation of spatially dependent dynamics without explicit description of space (right panels). The selected example here illustrates a spontaneous calcium wave, showing temporal snapshots of local calcium

Computing Bounds on the Eigenvalues of the Preconditioned X‐FFT System in 3D Linear Elastic Homogenization

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The previously introduced X‐FFT solver permits solving three‐dimensional linear elastic homogenization problems with high accuracy and efficiency. Due to the extended finite element discretization (X‐FEM), matrix‐inclusion problems may be approximated with the error convergence of interface‐conforming finite elements.

Topology, Orientation and Fiber Path Optimization for Layered Anisotropic Materials

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Topology optimization and additive manufacturing complement each other: the freedom offered by design optimization enables the creation of complex, highly efficient structures that are often feasible only with additive manufacturing. However, most structural optimization methods assume isotropic material properties, an assumption that ...

Regional Estimation of Wind Power Production in Finland Using k‐Means Clustering and Power Curve Fitting

open access: yesWind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT Wind power has become one of the fastest growing renewable energy sources globally and plays a central role in Finland's electrical grid system, where it already accounts for approximately one quarter of total electricity generation. The increasing penetration of converter‐interfaced wind power plants introduces challenges for grid stability ...

A Random Forest–Based Global Gridded Model for Vertical Correction of Precipitable Water Vapor Accounting for Nonlinear Vertical Variation

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Vertical correction of precipitable water vapor (PWV) is a critical step in PWV fusion and atmospheric research. To address the limited accuracy of traditional global‐scale PWV vertical correction models that do not explicitly account for nonlinear vertical variations, we developed RF‐PWV, a global 1° × 1° PWV vertical correction model based ...

Trends in new psychoactive substance poisonings in the Netherlands: A 14‐year retrospective analysis (2012–2025)

open access: yesAddiction, Volume 121, Issue 10, Page 2822-2832, October 2026.
Abstract Background and aims Data on the presence of new psychoactive substances (NPS) mainly originate from drug‐checking, law enforcement and wastewater analysis sources, while data on NPS poisonings are scarce. In Europe, the documented incidence rate of NPS poisonings is highest in the Netherlands.

Antecedent of Pregnancy‐Related Cardiometabolic Complication and Risk of Cardiovascular Disease Among Women With Type 2 Diabetes

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 10, Page 9222-9229, October 2026.
ABSTRACT Aim We investigated the contribution of antecedent gestational diabetes mellitus (GDM) or gestational hypertensive disorder (GHTD) to the risk of cardiovascular disease (CVD) among women with Type 2 diabetes mellitus (T2DM). Methods In a population‐based cohort using the Ministry of Health of Ontario (Canada) healthcare administrative data ...
