Pathogen Propagation Model with Superinfection in Vegetatively Propagated Plants on Lattice Space. [PDF]

open access: yesPLoS ONE, 2016
Many clonal plants have two reproductive patterns, seed propagation and vegetative propagation. By vegetative propagation, plants reproduce the genetically identical offspring with a low mortality, because resources are supplied from the other ...

Multi-criteria approach to pair-multiple linear regression models constructing [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
A pair-multiple linear regression model which is a synthesis of Deming regression and multiple linear regression model is considered. It is shown that with a change in the type of minimized distance, the pair-multiple regression model transforms smoothly

Variational approach for pair optimization in the nucleon pair approximation [PDF]

open access: yesPhysical Review C, 2020
We propose a pair-condensate variational approach (PCV) to determine a set of the most important collective pairs in the description of low-lying states in atomic nuclei. Having available the precise details on these key collective pairs -- their spin, parity, and structure -- can be particularly useful in calculations based on the nucleon-pair ...

Stochastic pair approximation treatment of the noisy voter model

open access: yesNew Journal of Physics, 2018
We present a full stochastic description of the pair approximation scheme to study binary-state dynamics on heterogeneous networks. Within this general approach, we obtain a set of equations for the dynamical correlations, fluctuations and finite-size ...

Parameterizing pair approximations for takeover dynamics [PDF]

open access: yesProceedings of the 10th annual conference companion on Genetic and evolutionary computation, 2008
Pair approximations have often been used to predict equilibrium conditions in spatially-explicit epidemiological and ecological systems. In this work, we investigate whether this method can be used to approximate takeover dynamics in spatially structured evolutionary algorithms. Our results show that the pair approximation, as originally formulated, is

Approximate isomorphism of randomization pairs

open access: yesConfluentes Mathematici, 2023
We study approximate ℵ 0 -categoricity of theories of beautiful pairs of randomizations, in the sense of continuous logic.

Improved approximation algorithms for degree-bounded network design problems with node connectivity requirements [PDF]

open access: yes, 2014
We consider degree bounded network design problems with element and vertex connectivity requirements. In the degree bounded Survivable Network Design (SNDP) problem, the input is an undirected graph G = (V, E) with weights w(e) on the edges and degree ...

Approximation Algorithms for Directed Weighted Spanners [PDF]

open access: yes, 2023
In the pairwise weighted spanner problem, the input consists of a weighted directed graph on n vertices, where each edge is assigned both a cost and a length. Furthermore, we are given k terminal vertex pairs and a distance constraint for each pair.

Neighborhood Approximations for Non-Linear Voter Models

open access: yesEntropy, 2015
Non-linear voter models assume that the opinion of an agent depends on the opinions of its neighbors in a non-linear manner. This allows for voting rules different from majority voting. While the linear voter model is known to reach consensus, non-linear

A New Single-Valued Neutrosophic Rough Sets and Related Topology

open access: yesJournal of Mathematics, 2021
(Fuzzy) rough sets are closely related to (fuzzy) topologies. Neutrosophic rough sets and neutrosophic topologies are extensions of (fuzzy) rough sets and (fuzzy) topologies, respectively. In this paper, a new type of neutrosophic rough sets is presented,
