background:epidemic dropsy occurs due to ingestion of mustard oil contaminated with oil from argemone mexicana, leading to edema and tenderness of the abdomen, upper and lower limbs. in this study, clinical profiles of patients presented with epidemic dropsy in north india are described. methods: this was a prospective study of patients presented with epidemic dropsy to the emergency department...

In this paper, we analyze dynamic switching networks where the networks switch arbitrarily among a set of topologies. For this class of dynamic networks, we derive an epidemic threshold considering the SIS epidemic model. First, an epidemic probabilistic model based on assumption of independence between states of nodes is developed. We identify conditions for the epidemic dying out by linearizi...

This paper presents a failure propagation model for transport networks which are affected by epidemic failures. The network is controlled using the GMPLS protocol suite. The Susceptible Infected Disabled (SID) epidemic model is investigated and new signaling functionality of GMPLS to support epidemic failure resolution is proposed. The results provide important input to service recovery mechani...

The variable generalised stochastic epidemic (VGSE) model which allows for variability in both the susceptibility and infectivity of individuals is analysed. A very different epidemic model which exhibits variable susceptibility and infectivity is the random graph epidemic model. A suitable coupling of the two epidemic models is derived, which enables us to show that, whilst the epidemics are v...

Empirical and mechanistic modeling indicate that pathogens transmitted via aerially dispersed inoculum follow a power law, resulting in dispersive epidemic waves. The spread parameter (b) of the power law model, which is an indicator of the distance of the epidemic wave front from an initial focus per unit time, has been found to be approximately 2 for several animal and plant diseases over a w...

To investigate the impact of weights on the traffic driven epidemic spreading in weighted homogeneous networks, an epidemic model in pseudo-random network with adjustable weights is presented. In the scenario that epidemic pathway is defined and driven by traffic flows, the epidemic spreading velocity of SI model in weighted homogeneous networks is obviously accelerated when the edge weight is ...

We propose a model describing the synergetic feedback between word-of-mouth (WoM) and epidemic dynamics controlled by voluntary vaccination. The key feature consists in combining a game-theoretic model for the spread of WoM and a compartmental model describing VSIR disease dynamics in the presence of a program of voluntary vaccination. We evaluate and compare two scenarios for determinants of b...

In this paper at rst, a history of mathematical models is given.Next, some basic information about random variables, stochastic processesand Markov chains is introduced. As follows, the entropy for a discrete timeMarkov process is mentioned. After that, the entropy for SIS stochastic modelsis computed, and it is proved that an epidemic will be disappeared after a longtime.
