On the edge chromatic vertex stability number of graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
For an arbitrary invariant [Formula: see text] of a graph G, the [Formula: see text]vertex stability number [Formula: see text] is the minimum number of vertices of G whose removal results in a graph [Formula: see text] with [Formula: see text] or with ...

High-Level Petri Nets as Type Theories in the Join Calculus [PDF]

open access: yes, 2001
We study the expressiveness of the join calculus by comparison with (generalised, coloured) Petri nets and using tools from type theory. More precisely, we consider four classes of nets of increasing expressiveness, $PN_i$, introduce a hierarchy of type ...

On partial inverse operations in the class of preradicals of modules

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In the present work two partial operations in the class of preradicals ℙℝ of the category R-Mod of left R-modules are defined and investigated. They are inverse operations for product with respect to meet and coproduct with respect to join.

Certain Operations on Complex Picture Fuzzy Graphs

open access: yesIEEE Access, 2022
A complex picture fuzzy set (Com-PFS) is a motivating tool for more precisely interpreting fuzzy notions. Recently, all extensions of complex fuzzy graphs (Com-FGs) have become a growing research topic as they handle ambiguous situations more explicitly ...

On Noncommutative Joinings [PDF]

open access: yesInternational Mathematics Research Notices, 2017
This paper extends the classical theory of joinings of measurable dynamical systems to the noncommutative setting from several interconnected points of view. Among these is a particularly fruitful identification of joinings with equivariant quantum channels between $W^{\ast}$-dynamical systems that provides noncommutative generalizations of many ...

The (Strong) Rainbow Connection Number of Join Of Ladder and Trivial Graph

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2023
Let G = (V,E) be a nontrivial, finite, and connected graph. A function c from E to {1,2,...,k},k ∈ N, can be considered as a rainbow k-coloring if every two vertices x and y in G has an x- y path.

To join or not to join: collective foraging strategies

open access: yesJournal of Physics: Conference Series, 2015
We present a minimal model to address the issue of how the interaction between foragers influence their encounter rates with resources. We consider a two-dimensional lattice model to study the optimal strategy for a group of foragers (walkers) searching for targets distributed heterogeneously. A forager who has not detected any target has the choice of,

The Joint Observation in Neonatology and Neurodevelopmental Outcome of Preterm Infants at Six Months Corrected Age: Secondary Outcome Data from a Randomised Controlled Trial [PDF]

open access: yes, 2022
This study aimed to evaluate the impact of a standardised joint observation (JOIN) performed in the neonatal intensive care unit (NICU) on the neurodevelopment of preterm infants at six months corrected age (CA) compared with a preterm control group.

Monophonic Distance Energy for Join of Some Graphs

open access: yesRatio Mathematica, 2023
Let G be a connected graph with n vertices and m edges. Let µ1, µ2 ,..., µn be the Eigen values of distance matrix of G. The distance energy of a graph ED (G) = \sum_{i=1}^{p}\left|{\mu_i}^\ \right|,was already studied.
