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 ...

Thresholds of Wave Forcing: Implications for Atoll Reef Dynamics Under Sea Level Rise

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract We investigate the response of shallow reef flow to tidal variability and wave exposure during a 4‐month field campaign in southern Huvadhu Atoll, Maldives. Incident waves breaking on steep fore reefs and reef crests generate a setup proportional to offshore wave height that drives a cross‐reef flow. We emphasize a critical threshold—where the

Boundary value problem solving for semilinear fractional differential equations with nonlocal and integral boundary conditions

, 2022
In this paper, we will study a boundary value problem for semilinear fractional differential equations of order q ∈ (1, 2] with nonlocal and integral boundary conditions. Some existence and uniqueness results with illustrative examples will be presented by applying some fixed point theorems.

A Novel Deep Learning Approach for TEC Map Completion Using Image Equation‐Guided Loss

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract This study introduces the Image Equation Mechanism‐Completion Generative Adversarial Network (IEM‐CGAN), a groundbreaking deep learning framework that revolutionizes the reconstruction of large‐scale global ionospheric total electron content (TEC) maps.

Predicting animal movement with deepSSF: A deep learning step selection framework

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 371-391, February 2026.
Abstract Predictions of animal movement are vital for understanding and managing wild populations. However, the fine‐scale, complex decision‐making of animals can pose challenges for the accurate prediction of trajectories. Integrated step selection functions (iSSFs), a common tool for inferring relationships between animal movement and the environment,

A complex network perspective on brain disease

Biological Reviews, Volume 101, Issue 1, Page 364-399, February 2026.
ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...

Tourist visits to Madagascar's protected areas linked to deforestation decreases within but increases outside protected area boundaries

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Abstract Tourist visits to protected areas (PAs) are a widely promoted, yet largely untested, approach to achieve forest conservation and socioeconomic development. We assessed the impacts of annual tourist visits to 40 Madagascar PAs over 20 years on local deforestation in and around PA boundaries, using a two‐way fixed effects approach to control for

Models in Decision‐Making Under Risk and Uncertainty

Journal of Economic Surveys, Volume 40, Issue 1, Page 304-320, February 2026.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...
