Herein, a virus dynamics model with cytotoxic T lymphocyte (CTL) and antibody immune responses is formulated analyzed. The considers two sorts of infected cells, latently cells actively which produce the virus. We incorporate both virus-to-cell cell-to-cell transmissions into model. To assure biological feasibility proposed model, we prove nonnegativity boundedness solutions derive five thresho...

A critical problem in the decision making process for dental prosthodontic treatment is the lack of reliable clinical parameters. This review discusses the limits of traditional normative treatment and presents guidelines for clinical decision making. There is a need to incorporate a sociodental approach to help determine patient's needs. Adoption of the evidence-based clinical practice model i...

The influence of multiple bottlenecks on the stability of Active Queue Management (AQM) controllers, usually configured on a single bottleneck basis is discussed. We consider a network scenario where RED is configured at each router according to previously developed control theoretic techniques. These configuration rules assure stability in a single bottleneck scenario. We show that instability...

quality assurance as a comprehensive term encompasses all policies, processes and actions maintaining and developing higher education quality. quality assurance emphasizes on external goals of evaluation, one of which is to assure learners, public and government that each unit, department, program or institution manages its quality. thus quality assurance focuses on accountability. this article...

This paper addresses the design of robust H2 filters for linear continuoustime systems subject to parameter uncertainty in the state-space model. The uncertain parameters are supposed to belong to a given convex bounded polyhedral domain. Two methods based on parameter-dependent Lyapunov functions are proposed for designing linear stationary asymptotically stable filters that assure asymptotic ...

Methods Using a model peptide pool that is comprised of 32 welldefined viral epitopes from Cytomegalovirus, Epstein-Barr virus, and Influenza virus (CEF peptide pool), we assessed peptide competition in PBMC from 43 human subjects. IFN-g was measured using the ImmunoSpot Test Kit, and to assure low background, serum-free, CTL-TestTM Medium was used. The spots were counted using an ImmunoSpot S6...
