Convergence properties of dynamic mode decomposition for analytic interval maps
Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 179-206, February 2026.Abstract Extended dynamic mode decomposition (EDMD) is a data‐driven algorithm for approximating spectral data of the Koopman operator associated to a dynamical system, combining a Galerkin method with N$N$ functions and a quadrature method with M$M$ quadrature nodes.

Dimer models and conformal structures
Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

Locally Adaptive Non‐Hydrostatic Shallow Water Extension for Moving Bottom‐Generated Waves
International Journal for Numerical Methods in Fluids, Volume 98, Issue 2, Page 159-173, February 2026.This study proposes a locally adaptive non‐hydrostatic model, which is based on the non‐hydrostatic extension of the shallow water equations (SWE) with a quadratic pressure relation, and applies it to wave propagation generated by a moving bottom. To obtain the locally adaptive model, we investigate several potential adaptivity criteria based on the ...

Stress and Health, Volume 42, Issue 1, February 2026.ABSTRACT Insufficient sleep is common among university students and impairs health and academic functioning. While multidimensional perfectionism (perfectionistic concerns and strivings) and daily stress are potential contributors, yet their interplay and underlying cognitive mechanisms remain unclear.

Dissipative energy functionals of passive linear time‐varying systems
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.Abstract The concept of dissipativity plays a crucial role in the analysis of control systems. Dissipative energy functionals, also known as Hamiltonians, storage functions, or Lyapunov functions, depending on the setting, are extremely valuable to analyze and control the behavior of dynamical systems, but in general circumstances they are very ...

FloodUnet: A Rapid Spatio‐Temporal Prediction Model for Flood Evolution Based on an Enhanced U‐Net
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Flooding causes significant loss of life and economic damage and affects healthy development of society. Deep learning (DL) models demonstrate significant advantages in improving computational efficiency while maintaining accuracy. Existing research of predicting dynamic flood evolution still remains some gaps for predicting flooding maps from

Journal of Sleep Research, Volume 35, Issue 1, February 2026.ABSTRACT The aim of the study was to compare the efficacy of intensive sleep retraining (ISR) and total sleep deprivation (TSD) against a no‐treatment control condition for treating chronic insomnia and examine two potential mechanisms: the resolution of conditioned insomnia and the increase in homeostatic sleep drive produced by sleep deprivation ...

Journal of Sleep Research, Volume 35, Issue 1, February 2026.ABSTRACT This study aimed to investigate the efficacy of a Danish adaption of a transdiagnostic sleep and circadian intervention, combining cognitive behavioural therapy for insomnia with chronotherapy. A randomised controlled trial enrolling 88 outpatients with depression, attention deficit disorder, or bipolar disorder suffering from insomnia or ...

Journal of Sleep Research, Volume 35, Issue 1, February 2026.ABSTRACT Co‐morbid insomnia and sleep apnoea (COMISA) is a prevalent and debilitating condition. Cognitive behavioural therapy for insomnia (CBTi) is an effective but largely inaccessible treatment in patients with COMISA. We aimed to test a self‐guided interactive digital CBTi program tailored for COMISA and insomnia alone.
