A Cost-Effectiveness-Assessing Model of Vaccination for Varicella and Zoster

M. Comba, S. Martorano-Raimundo, E. Venturino (2012)

Mathematical Modelling of Natural Phenomena

Similarity:

A decision analytical model is presented and analysed to assess the effectiveness and cost-effectiveness of routine vaccination against varicella and herpes-zoster, or shingles. These diseases have as common aetiological agent the varicella-zoster virus (VZV). Zoster can more likely occur in aged people with declining cell-mediated immunity. The general concern is that universal varicella vaccination might lead to more cases of zoster:...

Thermodynamics of DNA microarrays

Enrico Carlon (2008)

Banach Center Publications

Similarity:

DNA microarrays have been widely used in molecular biology laboratories. The main current application of these devices is the determination of the gene expression level for thousands of genes simultaneously. Here we review a recently introduced physical model for hybridization (i.e. the binding of complementary DNA strands) in Affymetrix arrays and compare it to experimental results. The experimental data follow rather well the microscopic model and the approach offers several advantages...

Human Impact Factor in the Research and Development of Educational Software

Boytchev, Pavel (2015)

Serdica Journal of Computing

Similarity:

This paper presents the long-term impact factor which a single person may have on a researcher. This is a description of the author’s research topics and the creation of educational software, which were either directly or indirectly affected by Prof. Edward Friedman.

Community-Sourcing in Virtual Societies

Branzov, Todor (2016)

Serdica Journal of Computing

Similarity:

The paper studies the approaches to development of goods with active participation of virtual community members. The concept of community-sourcing is presented as an alternative to the open source model and crowdsourcing. On that foundation a conceptual model of resource management system that use some current good practices of the IT industry is proposed. Results obtained in a virtual community implementing the model are presented as a validation attempt. ACM Computing Classification...

EPQ Model with Imperfect Quality Raw Material

El-Kassar, Abdul-Nasser, Salameh, Moueen, Bitar, Mokarram (2012)

Mathematica Balkanica New Series

Similarity:

MSC 2010: 26A33, 33E12, 33C60, 44A20 The classical economic production model (EPQ) has been extended in many directions to incorporate factors encountered in real-life situations. In this paper, an EPQ model that accounts for the cost of raw material needed for production is examined. It is assumed that the raw material acquired from the supplier contains a percentage of imperfect quality items. At the beginning of the inventory cycle, the raw material is received instantaneously,...
