Listeria monocytogenes is a very important life-threatening bacteria in certain risk groups such as neonates, pregnant women, elderly people, transplant recipients and others with impaired cell-mediated immunity. However, its infections are very rare in healthy children. Reports of listeriosis in newborn period are limited. We report a case of neonatal listeriosis with erythematous rash, intrac...

We consider five ordinal notation systems of ε0 which are all well-known and of interest in proof-theoretic analysis of Peano arithmetic: Cantor’s system, systems based on binary trees and on countable tree-ordinals, and the systems due to Schütte and Simpson, and to Beklemishev. The main point of this paper is to demonstrate that the systems except the system based on binary trees are equivale...

In this paper, we consider the global stability problem for the well known delayed chemostat model introduced and studied by Freedman, So and Waltman(1989). The difficulty of studying this open problem is that this delayed system has no negative feedback in the microbial populations. By a novel way of constructing a proper Liapunov functional and explicit estimates of eventual upper and lower b...

reduction technique used in data mining. It can reveal structure in data sets through data visualization that is otherwise hard to detect from raw data alone. However, interpretation through visual inspection is prone to errors and can be very tedious. There are several techniques for the automatic detection of clusters of code vectors found by SOM, but they generally do not take into account t...

Criteria based on disturbance rejection and system robustness are proposed to assess the performance of PID controllers. A simple robustness measure is defined and the integral gains of the PID controllers are shown to be a good measure for disturbance rejection. An analysis of some well-known PID tuning formulas reveals that the robustness measure should lie between 3 and 5 to have a good comp...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200808 DESCRIPTION A young alcoholic male patient was referred from another hospital with a history of loose stools and vomitings. There was documentation of hyponatraemia (Na-111 mEq/L) which was treated with intravenous normal saline. Next day, sodium was...

FORWARD Designing an interface between systems is not a simple or straight-forward task. Parameters that must be taken into account include: data rate, data format, cable length, mode of transmission, termination, bus common mode range, connector type, and system configuration. Noting the number of parameters illustrates how complex this task actually is. Additionally, the interface’s compatibi...
