On the growth of one-dimensional reverse immunization contact processes

Author(s) : Tzioufas, Achilleas
Description : We are concerned with the supercritical contact process modified so that first infection occurs at a lower rate, it is known that the process survives with positive probability. Regarding the rightmost infected of the process started from one site infected and conditioned to survive, we specify a ...

Contact processes on the integers

Author(s) : Tzioufas, Achillefs
Description : The three state contact process is the modification of the contact process at rate $\mu$ in which first infections occur at rate $\lambda$ instead. Chapters 2 and 3 consider the three state contact process on (graphs that have as set of sites) the integers with nearest neighbours interaction (that...

A note on Mountford and Sweet's extension of Kuczek's argument to non-nearest neighbours contact processes

Author(s) : Tzioufas, Achilleas
Description : An elementary proof of the i.i.d. nature of the growth of the right endpoint is presented. A related large deviations result for the density of oriented percolation is also given.

Rates of convergence for the three state contact process in one dimension

Author(s) : Tzioufas, Achillefs
Description : The basic contact process with parameter $\mu$ altered so that infections of sites that have not been previously infected occur at rate proportional to $\lambda$ instead is considered. Emergence of an infinite epidemic starting out from a single infected site is not possible for $\mu$ less than th...

An aspect of particles' spatial competition

Author(s) : Tzioufas, Achillefs
Description : The branching random walk is shown to be monotone decreasing in ascending direction of integer lattices as a corollary of an observation in regard to the lineage of particles from antisymmetric initial states, and a related property of percolation paths on the usual oriented lattices is also given...

Current Aspects of Pathogenesis in Sjögren's Syndrome

Description : Sjögren's syndrome is a chronic autoimmune process that primarily affects the exocrine glands and leads to their functional impairment. The exocrine gland involvement is characterized by a focal, mononuclear cell infiltrate which is accumulated around ducts and, in some patients, extends and replace...

Lupus thrombocytopenia: clinical implications and prognostic significance

Description : Methods: 632 patients were reviewed retrospectively. Fifty patients with thrombocytopenia were included as cases and matched with 100 control patients. Clinical manifestations at first thrombocytopenic episode were recorded. Classification criteria at diagnosis, basic immunological profiles, disease...

RNA Recognition Motif (RRM) of La/SSB: The Bridge for Interparticle Spreading of Autoimmune Response to U1-RNP

Description : Systemic lupus erythematosus (SLE) is characterized by the production of grouped sets of autoantibodies targeting mainly the U1 ribonucleoprotein (RNP) and/or Ro/La RNP particles. Intraparticle diversification of the autoimmune response is believed to occur via epitope spreading. So far, it is not k...
