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.

High Performance Methods for Linked Open Data Connectivity Analytics

Information, 2018
The main objective of Linked Data is linking and integration, and a major step for evaluating whether this target has been reached, is to find all the connections among the Linked Open Data (LOD) Cloud datasets.

Parallel transitive closure algorithm [PDF]

Journal of the Brazilian Computer Society, 2012
Abstract Using the BSP/CGM model, with $$p$$ processors, where $$p \ll n$$ , we present a parallel algorithm to compute the transitive closure of a digraph $$D$$ with $$n$$ vertices and $$m$$ edges.

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 ...

ID-based transitive signature schemes without random oracle

Tongxin xuebao, 2010
Based on waters’ signature scheme,the first identity-based transitive signature scheme was proposed and proved secure against attacks in the standard model.Compared with current transitive signature schemes,the unforgeability of the signature’s ...

Perov Fixed-Point Results on F-Contraction Mappings Equipped with Binary Relation

Mathematics, 2023
The purpose of this article is to discuss some new aspects of the vector-valued metric space. The idea of an arbitrary binary relation along with the well-known F contraction is used to demonstrate the existence of fixed points in the context of a ...

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 ...

Common purpose advantage: Reviving a managerial theory of the firm?

Strategic Management Journal, EarlyView.
Abstract Research Summary What is the most effective way to distribute organizational objectives across managers? While prior work suggests managers should each focus on a single objective, we draw on Barnard's original insights on corporate purpose to identify conditions when managers pursuing the full set of objectives is advantageous.

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

Journal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

Can the vector space model be used to identify biological entity activities?

BMC Genomics, 2011
Background Biological systems are commonly described as networks of entity interactions. Some interactions are already known and integrate the current knowledge in life sciences.
