Geometric Interpretation of Surface Tension Equilibrium in Superhydrophobic Systems
Entropy, 2015 Surface tension and surface energy are closely related, although not identical concepts. Surface tension is a generalized force; unlike a conventional mechanical force, it is not applied to any particular body or point.

Lost in Translation? Risk‐Adjusting RMSE for Economic Forecast Performance
Journal of Forecasting, EarlyView.ABSTRACT When used for parameter optimization and/or model selection, traditional mean squared error (MSE)–based measures of forecast accuracy often exhibit a weak or even negative correlation with the economic value of return forecasts measured by, for example, the Sharpe ratios of the resulting portfolios.

Ground state solutions for asymptotically periodic fractional Choquard equations
Electronic Journal of Qualitative Theory of Differential Equations, 2019 This paper is dedicated to studying the following fractional Choquard equation \begin{equation*} (-\triangle)^s u+V(x)u=\left(\int_{\mathbb{R}^N}\frac{Q(y)F(u(y))}{|x-y|^\mu}\mathrm{d}y\right)Q(x)f(u), \qquad u\in H^s(\mathbb{R}^{N}), \end{equation*

Operator inequalities via the triangle inequality
Journal of Mathematical InequalitiesThis article improves the triangle inequality for complex numbers, using the Hermite-Hadamard inequality for convex functions. Then, applications of the obtained refinement are presented to include some operator inequalities. The operator applications include numerical radius inequalities and operator mean inequalities.

Human Resource Development Quarterly, EarlyView.ABSTRACT Workplace bullying (WB) remains a pervasive concern across all sectors, including higher education institutions (HEIs), where shifting power dynamics, performance pressures, and transformation mandates often create fertile ground for systemic abuse.

JCPP Advances, EarlyView.This study explored resilience in Black and South Asian Muslim children aged 7–12 in East London, an underrepresented group affected by deprivation and discrimination. Using body mapping, children depicted resilience as personal strength and described the importance of support systems.

Two row mixed integer cuts via lifting [PDF]
Recently, Andersen et al. [1], Borozan and Cornuéjols [6] and Cornuéjols and Margot [9] characterized extreme inequalities of a system of two rows with two free integer variables and nonnegative continuous variables.

Treewidth Versus Clique Number. V. Further Connections With Tree‐Independence Number
Journal of Graph Theory, EarlyView.ABSTRACT We continue the study of ( tw , ω ) $({\mathsf{tw}},\omega )$‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by ...

An Improved Quasi‐Isometry Between Graphs of Bounded Cliquewidth and Graphs of Bounded Treewidth
Journal of Graph Theory, EarlyView.ABSTRACT Cliquewidth is a dense analogue of treewidth. It can be deduced from recent results by Hickingbotham [arXiv:2501.10840] and Nguyen, Scott, and Seymour [arXiv:2501.09839] that graphs of bounded cliquewidth are quasi‐isometric to graphs of bounded treewidth.
