Risk stratification using coronary artery calcium and potential benefit of semaglutide therapy: A cost‐effectiveness modelling study

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aim Coronary artery calcium (CAC) scoring is observed to improve risk stratification for major adverse cardiovascular events (MACE). Semaglutide, a recently introduced anti‐obesity drug, is very effective, but wider use is limited due to high costs.

Harnessing Human Mobility Data for Applied Economic Research: Current Knowledge, Challenges, and Emerging Opportunities

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper reviews how large‐scale mobility data can enhance economic analyses, highlighting its contributions to understanding travel behavior, labor markets, social interactions, and health outcomes. We discuss its advantages over traditional mobility data sources, which include real‐time location information and fine spatial resolution ...

SVD-MPE: An SVD-Based Vector Extrapolation Method of Polynomial Type

Applied Mathematics, 2016
An important problem that arises in different areas of science and engineering is that of computing the limits of sequences of vectors $\{\xx_m\}$, where $\xx_m\in \C^N$, $N$ being very large. Such sequences arise, for example, in the solution of systems of linear or nonlinear equations by fixed-point iterative methods, and $\lim_{m\to\infty}\xx_m$ are

Tensor Changepoint Detection and Eigenbootstrap

Journal of Time Series Analysis, EarlyView.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

EuroSCORE II: Current limitations and physiological gaps in risk stratification

Experimental Physiology, EarlyView.
Abstract Risk stratification remains critical in cardiac surgery, enabling clinicians to predict adverse outcomes and guide perioperative management. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, introduced in 2011, incorporates 18 key variables to provide an evidence‐based approach to risk assessment.

The Effect of Pretend Play on Children's Social Competence: An Intervention Study in Early Childhood Education

Social Development, Volume 35, Issue 2, May 2026.
ABSTRACT Within cultural‐historical activity theory, pretend play is considered crucial for the development of young children's social competence. However, the existing empirical evidence does not support such strong causal claims. Given the importance of social competence for children's development, the current study aimed to contribute to a better ...

What If Each Voxel Were Measured With a Different Diffusion Protocol?

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2277-2290, April 2026.
ABSTRACT Purpose Expansion of diffusion MRI (dMRI) both into the realm of strong gradients and into accessible imaging with portable low‐field devices brings about the challenge of gradient nonlinearities. Spatial variations of the diffusion gradients make diffusion weightings and directions non‐uniform across the field of view, and deform perfect ...
