The women made it work: fuzzy transitive closure of the results chain in a dengue prevention trial in Mexico [PDF]

open access: yesBMC Public Health, 2017
Background A modified theory of planned behaviour (acronym CASCADA) proposes that Conscious knowledge precedes a change in Attitude, which in turn precedes positive deviations from negative Subjective norms, intention to Change, perception of Agency to ...

Algebraic structures for transitive closure [PDF]

open access: greenTheoretical Computer Science, 1977
Closed semi-rings and the closure of matrices oven closed semirings are defined and studied. Closed semirings are structures weaker than the structunes studied by Conway [3] and Aho, Hopcnoft and Ullman [1].

Finding the Transitive Closure of Functional Dependencies using Strategic Port Graph Rewriting [PDF]

open access: diamondElectronic Proceedings in Theoretical Computer Science, 2019
We present a new approach to the logical design of relational databases, based on strategic port graph rewriting. We show how to model relational schemata as attributed port graphs and provide port graph rewriting rules to perform computations on ...

Parallel tiled Nussinov RNA folding loop nest generated using both dependence graph transitive closure and loop skewing [PDF]

open access: yesBMC Bioinformatics, 2017
Background RNA secondary structure prediction is a compute intensive task that lies at the core of several search algorithms in bioinformatics. Fortunately, the RNA folding approaches, such as the Nussinov base pair maximization, involve mathematical ...

Automata with Nested Pebbles Capture First-Order Logic with Transitive Closure [PDF]

open access: yesLogical Methods in Computer Science, 2007
String languages recognizable in (deterministic) log-space are characterized either by two-way (deterministic) multi-head automata, or following Immerman, by first-order logic with (deterministic) transitive closure.

Transitive-Closure Spanners [PDF]

open access: greenSIAM Journal on Computing, 2009
Given a directed graph G = (V,E) and an integer k>=1, a k-transitive-closure-spanner (k-TC-spanner) of G is a directed graph H = (V, E_H) that has (1) the same transitive-closure as G and (2) diameter at most k. These spanners were implicitly studied in access control, data structures, and property testing, and properties of these spanners have been

Transitive Closure of Interval-valued Fuzzy Relations [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2013
In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity.

Model Checking Synchronized Products of Infinite Transition Systems [PDF]

open access: yesLogical Methods in Computer Science, 2007
Formal verification using the model checking paradigm has to deal with two aspects: The system models are structured, often as products of components, and the specification logic has to be expressive enough to allow the formalization of reachability ...

Market formation as transitive closure: The evolving pattern of trade in music [PDF]

open access: greenNetwork Science, 2015
Where do new markets come from? I construct a network model in which national markets are nodes and flows of recorded music between them are links and conduct a longitudinal analysis of the global pattern of trade in the period 1976–2010.
