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

TRACT: Denoising Diffusion Models with Transitive Closure Time-Distillation [PDF]
arXiv.org, 2023 Denoising Diffusion models have demonstrated their proficiency for generative sampling. However, generating good samples often requires many iterations.

Decrementai Transitive Closure and Shortest Paths for Planar Digraphs and Beyond [PDF]
ACM-SIAM Symposium on Discrete Algorithms, 2018 In this paper we show that the tools used to obtain the best state-of-the-art decremental algorithms for reachability and approximate shortest paths in directed graphs can be successfully combined with the existence of small separators in certain graph ...

Cyclic Proofs, Hypersequents, and Transitive Closure Logic [PDF]
International Joint Conference on Automated Reasoning, 2022 We propose a cut-free cyclic system for Transitive Closure Logic (TCL) based on a form of hypersequents, suitable for automated reasoning via proof search. We show that previously proposed sequent systems are cut-free incomplete for basic validities from

Reconstruction Method of Ocean Front Model Based on Fuzzy Cluster Analysis of Sound Speed Profile
IEEE Access, 2021 Ocean fronts are mostly determined according to the horizontal temperature gradient, and various selection criteria may lead to different frontal zones. This study proposes a frontal zone delineation method based on sound speed profile.

L-Recursion and a new Logic for Logarithmic Space [PDF]
Logical Methods in Computer Science, 2013 We extend first-order logic with counting by a new operator that allows it to formalise a limited form of recursion which can be evaluated in logarithmic space.

Journal of Clinical Psychology, Volume 79, Issue 1, Page 186-200, January 2023., 2023 Abstract Objectives This study tests ways in which the perception of intergenerational continuity in parenting behaviors among child‐maltreatment (CM) and non‐CM families conform to Benjamin's (2006) Copy Process Theory, which considers three copy processes: Identification (be like him/her), Recapitulation (behave as if he/she is still present and in ...

Spanning eulerian subdigraphs in semicomplete digraphs
Journal of Graph Theory, Volume 102, Issue 3, Page 578-606, March 2023., 2023 Abstract A digraph is eulerian if it is connected and every vertex has its in‐degree equal to its out‐degree. Having a spanning eulerian subdigraph is thus a weakening of having a hamiltonian cycle. In this paper, we first characterize the pairs (D,a) $(D,a)$ of a semicomplete digraph D $D$ and an arc a $a$ such that D $D$ has a spanning eulerian ...

Characterization of Transitivity in L-Tolerance Spaces by Convergence and Closure
Axioms, 2021 We show that the category of quantale-valued tolerance spaces is isomorphic to a category of quantale-valued convergence spaces. We define suitable quantale-valued closure functions and use them to characterize transitivity axioms.

Transitive closure in a polluted environment
The Annals of Applied Probability, 2023 We introduce and study a new percolation model, inspired by recent works on jigsaw percolation, graph bootstrap percolation, and percolation in polluted environments. Start with an oriented graph $G_0$ of initially occupied edges on $n$ vertices, and iteratively occupy additional (oriented) edges by transitivity, with the constraint that only open ...
