Adaptive Warning Thresholds for Dam Safety: A KDE-Based Approach

Infrastructures
Dams are critical infrastructures that provide essential services such as water supply, hydroelectric power generation, and flood control. As many dams age, the risk of structural failure increases, making safety assurance more urgent than ever ...

Reduced order models for thermally coupled low Mach flows

Advanced Modeling and Simulation in Engineering Sciences, 2018
In this paper we present a collection of techniques used to formulate a projection-based reduced order model (ROM) for zero Mach limit thermally coupled Navier–Stokes equations. The formulation derives from a standard proper orthogonal decomposition (POD)

On the Convergence of Conjugate Gradient and GMRES Algorithms in the Forward Backward Sweep Method for Optimal Control

Optimal Control Applications and Methods, Volume 47, Issue 2, Page 498-510, March/April 2026.
Optimal control combines state and adjoint equations, which yield the state (x$$ x $$) and adjoint (lambda) variables as a function of the control variables (u$$ u $$). This structure allows us to design strategies for iteratively updating the control variable, based on conjugate gradient (CG) or GMRES algorithms.

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Effect of a Spray Containing Occlusive Agents, Humectants and Physiological Lipids on Skin Hydration of Healthy Dogs When Applied After Bathing With a Chlorhexidine 2%/Miconazole 2% Shampoo

Veterinary Dermatology, Volume 37, Issue 1, Page 140-147, February 2026.
Background: Normal hydration of the canine epidermis is imperative for cutaneous homeostasis. Xerosis may be encountered in canine atopic dermatitis and may be aggravated by topical antiseptics. Hypothesis and Objectives: To evaluate the hydrating properties and the safety of a spray (Sensiderm spray; MP Labo) when applied after shampooing healthy dogs

Negative attitudes of an indigenous community are associated with lethal control of rodents in a temperate forest of Mexico

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
The essential ecological roles of rodents are often overlooked, as they can decimate crops and spread diseases. We aimed to unpack the knowledge, attitudes and control practices of farmers and foresters towards rodents from an indigenous community in Nuevo San Juan, Mexico.
