In this paper we establish a relation between the spread of infectious diseases and the dynamics of so called M/G/1 queues with processor sharing. The relation between the spread of epidemics and branching processes, which is well known in epidemiology, and the relation between M/G/1 queues and birth death processes, which is well known in queueing theory, will be combined to provide a framewor...

We study characterization of separable (classically correlated) states for composite systems of distinguishable fermions. In the computation of entanglement formation for such systems where located subsystems are coupled by the canonical anticommutation relations (not by tensor product), the state decompositions to be taken should respect the univalence superselection rule. (The usual entanglem...

By incorporating segregated spatial domain and individual-based linkage into the SIS (susceptible-infected-susceptible) model, we investigate the coupled effects of random walk and intragroup interaction on contagion. Compared with the situation where only local movement or individual-based linkage exists, the coexistence of them leads to a wider spread of infectious disease. The roles of narro...

in an international connection which different factors of legal relation were spread in different countries, bringing of several actions with the same object in different countries court was completely probable. each party with various reasons seeks litigation in a court which provides their interest in better way. however parallel litigation in it he same object impose burdensome charges on li...

the global spread of english, co-occurring with globalization, has generated new views towards some issues in english language teaching, one of which being the place of home culture versus foreign language culture in english language classes. the following study aimed to compare the viewpoint of three groups, i.e. language teachers, language learners and parents regarding the role of home cultu...
