Resilience of ant communities (Hymenoptera: formicidae) to moderate urban disturbance in a mediterranean peri-urban landscape

Abstract Human activities alter the biotic and abiotic characteristics of the environment, affecting species richness, population abundances and community composition. Nevertheless, these activities intensify as we move from forested areas to the center of urban cities, with peri...

Disjunctive Programming and Piecewise Convexity: An Algorithmic Trajectory Analysis Toward Stationary Points to Avoid the Maratos Effect in Numerical Optimization

In this paper, we present an algorithmic modeling approach based on Disjunctive Programming using Boolean logic “OR” to solve the Optimal Phasor Measurement Unit Placement (OPP). We propose a framework for modeling the optimal PMU placement subject to disjunctive constraints. A c...

Symbiotic visual creativity in higher education: Escape-room pedagogy across analogue, digital, and AI-mediated practice

Visual creativity is increasingly recognised as a foundational competency in higher education, particularly within disciplines grounded in digital interaction, interface design, and multimodal communication. Yet foundational perceptual frameworks such as Gestalt principles are fr...
