Effects of density of infected population to the spreading of HIV epidemic in communities

Mukwembi, Simon - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 21, pp. 3915-3921

We present a dynamical model for the spread of HIV in a finite discrete population of size n represented by the set V …’s sexual partners, and a reasonable amount of the influence of noninfectious HIV positive individuals on HIV infectious … certain network properties, is then used to analyse and investigate the existence of epidemic and stability in the HIV …

Measuring the Power of Nodes in Digraphs

Herings, P. Jean-Jacques; van der Laan, Gerard; Talman, Dolf - 2001

Many economic and social situations can be represented by a digraph. Both axiomatic and iterativemethods to determine the strength or power of all the nodes in a digraph have been proposed inthe literature. We propose a new method, where the power of a node is determined by both thenumber of its...

On the stability of cooperation structures

Haeringer, Guillaume - 2002

This paper studies the payoff structure of stable cooperation structures in link formation games. Players choose non-cooperatively with whom they want to form a link, and the payoffs are given by the Myerson value of the cooperation structure obtained. We characterize the class of TU-games that...

Generalization of Binomial Coefficients to Numbers on the Nodes of Graphs

Khmelnitskaya, Anna; van der Laan, Gerard; Talman, Dolf - 2016

of Pascal's triangle can be seen as a line-graph, to each node of which the corresponding binomial coefficient is … assigned. We show that the binomial coefficient of a node is equal to the number of ways the line-graph can be constructed when … sequences of binomial coefficients on each row of Pascal's triangle to so-called Pascal graph numbers assigned to the nodes of …

Fixed-effect regressions on network data

Jochmans, Koen; Weidner, Martin - 2017

This paper studies inference on fixed effects in a linear regression model estimated from network data. An important special case of our setup is the two-way regression model, which is a workhorse method in the analysis of matched data sets. Networks are typically quite sparse and it is...

Fixed-effect regressions on network data

Jochmans, Koen; Weidner, Martin - 2018

This paper considers inference on fixed effects in a linear regression model estimated from network data. An important special case of our setup is the two-way regression model. This is a workhorse technique in the analysis of matched data sets, such as employer-employee or student-teacher panel...

Axioms for Centrality Scoring with Principal Eigenvectors

Kitti, Mitri - 2012

represented by a directed graph and the question of ranking or scoring the alternatives can be turned into the question of … assessing the centrality of nodes of the graph. This paper characterizes the principal eigenvector as a scoring function with a …
