Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS). Although the causes are not known, the pathogenesis likely involves complex relationships between autoimmunity, immunogenetics, immunologic deficiency and viral infection. The evidence for such interrelationships is discussed.

The task of alert detection in event logs, i.e. determining which events in the event log require action from an administrator, is very important in preventing or recovering from downtime events. The ability to do this automatically and accurately provides significant savings in time and cost of downtime events. In this work we combine message type extraction based alert detection with the entr...

We have calculated constraints on the evolution of the equation of state of the dark energy, w(z), from a joint analysis of data from the cosmic microwave background, large scale structure and type-Ia supernovae. In order to probe the timeevolution of w we propose a new, simple parametrization of w, which has the advantage of being transparent and simple to extend to more parameters as better d...

We conducted a systematic review on the performance of diagnostic tests for clinical and laboratory monitoring of HIV-infected adults in developing countries. Diagnostic test information collected from computerized databases, bibliographies and the Internet were categorized as clinical (non-laboratory patient information), immunologic (information from immunologic laboratory tests), or virologi...
