Leptospirosis is a zoonosis found worldwide that is caused by a spirochete. The main reservoirs of Leptospira, which presents an asymptomatic infection, are wild rodents, including the brown rat (Rattus norvegicus). Experimental studies of the mechanisms of its renal colonization in rats have previously used an intraperitoneal inoculation route. However, knowledge of rat-rat transmission requir...
In order to make the sensing data in the monitoring equipment’s sensor nodes reach to the monitoring center as soon as possible and deal with the equipment which has some problems, the network time delay should be guaranteed in the accessible Time Delay Bound. The paper mainly researches the transmission scheduling algorithm with the chain framework, which adopts the Token to do the transmissio...
An adaptive routing mechanism is described that generates routing paths dynamically for a network of ad hoc wireless sensor nodes. The mechanism enables sensor nodes to minimize route cost by varying their transmission range, and by experimenting with the neighbours from which they forward data. Three route cost functions were compared. The route cost function that sums the link costs was found...
Background and Objectives: Acquired immunodeficiency syndrome (AIDS) is one of the important pandemic diseases in different societies. Since the beginning of the epidemic, almost 71 million people have been infected with the human immunodeficiency virus (HIV) and about 34 million people have died of HIV. Prevention as the most important method is proposed to deal with the HIV epidemic in the wo...
In this paper, we propose new methods for investigating the extent of heterogeneity in effective contact rates relevant to the transmission of infections. These methods exploit the correlations between ages at infection for different infections within individuals. The methods are developed for serological surveys, which provide accessible individual data on several infections, and are applied t...
