Attractors and upper semicontinuity for an extensible beam with nonlocal structural damping

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.
Abstract We analyze the asymptotic behavior of a class of extensible beam models governed by a nonlocal structural damping mechanism of the form φ(El)(−Δ)βut$\varphi (E_l)(-\Delta)^{\beta }u_t$, where β∈λ=(0,1]$\beta \in \lambda =(0,1]$. The coefficient φ$\varphi$ is a degenerate C1$C^{1}$‐function depending on the linear energy El$E_l$ of the system ...

Modal Analysis of Water Distribution Systems With the Elastic Water Column Model

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract This paper presents a modal and participation factor (PF) analysis of water distribution systems (WDSs) using the elastic water column model (EWCM). Modal analysis, widely used in other engineering fields, is adapted here to characterize the dynamic behavior of WDSs under transient conditions. By linearizing the EWCM around an operating point,

Previously Uncharacterised Aliphatic Amino Acid Positions Modulate the Apparent Catalytic Activity of the EAL Domain of ZMO_1055 and Other Cyclic Di‐GMP‐Specific EAL Phosphodiesterases

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
The A526V substitution, previously not recognised to affect the functionality of the EAL domain, downregulates the apparent catalytic activity of the PAS‐GGDEF‐EAL ZMO1055 phosphodiesterase and other GGDEF‐EAL proteins. Substitution of A526, which is conserved among homologues, with amino acids with longer aliphatic side chains than valine, reverts to ...

Pharmacokinetics, pharmacodynamics, and safety interaction study of tunodafil hydrochloride and alcohol: A randomized, blinded, placebo‐controlled, three‐cycle crossover study in Chinese healthy men

Andrology, Volume 14, Issue 2, Page 466-479, February 2026.
Abstract Objectives This study aimed to evaluate the pharmacodynamic effects of administering tunodafil hydrochloride with alcohol on blood pressure and heart rate in healthy Chinese males, and to investigate the mutual pharmacokinetic interactions and safety of the combination.

Descriptive Analysis of Periodontitis Case Detection and Selected Comorbidities in Danish Private Dental Practices

Journal of Clinical Periodontology, Volume 53, Issue 2, Page 214-221, February 2026.
ABSTRACT Aim To determine (i) the parameters used by dental professionals to evaluate patients with periodontitis, (ii) the prevalence of periodontitis using different case definitions and (iii) associations between periodontitis and diabetes mellitus, cardiovascular disease and rheumatoid arthritis among adult patients in private practices in Denmark.

Machine Learning‐Aided Spatial Adaptation for Improved Digital Image Correlation Analysis of Complex Geometries

Strain, Volume 62, Issue 1, February 2026.
ABSTRACT Digital image correlation (DIC) is a widely used experimental technique for measuring full‐field deformation, but its application to complex scenarios involving large deformations, discontinuities, or intricate geometries is often hampered by the need for manual region of interest (ROI) definition.

Real‐Time Optimal Control of High‐Dimensional Parametrized Systems by Deep Learning‐Based Reduced Order Models

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT Steering a system towards a desired target in a very short amount of time is a challenging task from a computational standpoint. Indeed, the intrinsically iterative nature of optimal control problems requires multiple simulations of the state of the physical system to be controlled. Moreover, the control action needs to be updated whenever the
