Parameterized Complexity and Approximation Issues for the Colorful Components Problems

, 2018
The quest for colorful components (connected components where each color is associated with at most one vertex) inside a vertex-colored graph has been widely considered in the last ten years.

Complements and transitive closures

Discrete Mathematics, 1972
AbstractThe complement of the transitive closure of the complement of a transitive relation is transitive. We prove this fact in three ways, analyze the underlying structure and consider various refinement's and applications.

Alignment and Differentiation: How Language and Network Proximity Drive Opinion‐Based Group Formation Online

European Journal of Social Psychology, EarlyView.
ABSTRACT This study examines the interplay between language and social connectedness in forming opinion‐based groups on social media. Drawing on small‐world theory and social identity theory, we propose a dual‐layer approach that combines semantic and network analysis to investigate the dynamics of group formation on X/Twitter during the 2021 COVID‐19 ...

Caste as a Social Kind

Journal of Applied Philosophy, EarlyView.
ABSTRACT Gender and race have received significant philosophical attention recently; they are the paradigm cases of social kinds in most philosophical accounts. I argue for the inclusion of caste as a social kind because it affects the lives of many people, and because it presents itself as an important test case for philosophers of social kinds.

Unravelling the Major Cardiovascular Risks of Systemic Psoriasis Medications: A Literature Systematic Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Psoriasis is a chronic inflammatory dermatological condition associated with an elevated risk of cardiovascular events (CVEs). Systemic therapies have transformed disease management, but their cardiovascular (CV) safety profiles remain incompletely understood and inconsistently reported.

Attribute Implication Bases From Galois Connection Structures

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.

Comparative Efficacy of Metabolic/Bariatric Surgery Versus GLP‐1 Receptor Agonists: A Network Meta‐Analysis of Randomized Controlled Trials

Obesity, EarlyView.
ABSTRACT Objective This study compared the efficacy of metabolic/bariatric surgery (MBS) and GLP‐1 receptor agonists (GLP‐1 RAs), including dual GLP‐1/GIP analogues, for weight and metabolic outcomes in adults with obesity. Methods A network meta‐analysis of randomized controlled trials compared MBS or GLP‐1 RAs versus lifestyle intervention in adults ...

Robust Control Design and Analysis Based on Lifting Linearization of Nonlinear Systems Under Uncertain Initial Conditions

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents a robust control synthesis and analysis framework for nonlinear systems with uncertain initial conditions. First, a deep learning‐based lifting approach is proposed to approximate nonlinear dynamical systems with linear parameter‐varying (LPV) state‐space models in higher‐dimensional spaces while simultaneously ...
