Grounded Fixpoints and Active Integrity Constraints [PDF]

open access: yes, 2016
The formalism of active integrity constraints was introduced as a way to specify particular classes of integrity constraints over relational databases together with preferences on how to repair existing inconsistencies.

Computational 2D Materials Database: Electronic Structure of Transition-Metal Dichalcogenides and Oxides [PDF]

open access: yes, 2015
We present a comprehensive first-principles study of the electronic structure of 51 semiconducting monolayer transition-metal dichalcogenides and -oxides in the 2H and 1T hexagonal phases.

Coarse Dynamics for Coarse Modeling: An Example From Population Biology

open access: yesEntropy, 2014
Networks have become a popular way to concisely represent complex nonlinear systems where the interactions and parameters are imprecisely known. One challenge is how best to describe the associated dynamics, which can exhibit complicated behavior ...

A flexible and scalable scheme for mixing computed formation energies from different levels of theory

open access: yesnpj Computational Materials, 2022
Computational materials discovery efforts are enabled by large databases of properties derived from high-throughput density functional theory (DFT), which now contain millions of calculations at the generalized gradient approximation (GGA) level of ...

Firms Growth Dynamics, Competition and Power Law Scaling [PDF]

open access: yes, 2002
We study the growth dynamics of the size of manufacturing firms considering competition and normal distribution of competency. We start with the fact that all components of the system struggle with each other for growth as happened in real competitive ...

Social Choice Methods for Database Aggregation [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
Knowledge can be represented compactly in multiple ways, from a set of propositional formulas, to a Kripke model, to a database. In this paper we study the aggregation of information coming from multiple sources, each source submitting a database ...

Application of complexity theory in health and social care research: a scoping review

open access: yesBMJ Open, 2023
Background Complexity theory has been chosen by many authors as a suitable lens through which to examine health and social care. Despite its potential value, many empirical investigations apply the theory in a tokenistic manner without engaging with its ...

Coherent Integration of Databases by Abductive Logic Programming

open access: yes, 2004
We introduce an abductive method for a coherent integration of independent data-sources. The idea is to compute a list of data-facts that should be inserted to the amalgamated database or retracted from it in order to restore its consistency. This method
