A recent paper (Math. Biosci. and Eng. (2008) 5:389-402) presented an SEIR model using an infinite delay to account for varying infectivity. The analysis in that paper did not resolve the global dynamics for R0 >1. Here, we show that the endemic equilibrium is globally stable for R0 >1. The proof uses a Lyapunov functional that includes an integral over all previous states.

In this article, we use a genetic algorithm to obtain an economically optimal preventive maintenance frequency for different equipment, the parts inventory policy (number and type of spare parts to keep in stock), and labor allocation in process plants. To assess cost, we improved a previously published Monte Carlo simulationbased maintenance model (Nguyen et al. Ind. Eng. Chem. Res. 2008, 47(6...

The Hellenic Journal of Nuclear Medicine is about to celebrate its 20th anniversary end of 2017. On board of the editorial team since 2003, this journal has influenced me like a good friend over the many past years. From time to time, the journal has published interesting and valuable historical notes. They show that nuclear medicine has a history and that medicine is its basis. They also teach...

Endoglin (Eng) is a transmembrane glycoprotein that is mainly expressed in endothelial cells, but it is also present in the epidermis and skin appendages. To address the role of Eng in cutaneous wound healing, we compared the kinetics of reepithelialization in Eng heterozygous null (Eng(+/-)) mice and their normal littermates (Eng(+/+)) following skin wounds. The wound area was significantly la...

This paper deals with preventive maintenance optimization problem for multi-state systems (MSS). This problem was initially addressed and solved by Levitin and Lisnianski [Optimization of imperfect preventive maintenance for multi-state systems. Reliab Eng Syst Saf 2000;67:193–203]. It consists on finding an optimal sequence of maintenance actions which minimizes maintenance cost while providin...
