Disseminated intravascular coagulation from disseminated histoplasmosis in uncontrolled HIV - Case report.

This case report describes an atypical presentation of a relatively common opportunistic infection, without documented exposure to areas known at the time to be endemic, resulting in catastrophic complications. The patient presented with a two month progressive history of vomiting, diarrhea, productive cough, and shortness of breath, on the background of poorly-controlled HIV. There was a low index of suspicion for infection with histoplasmosis, particularly given the large differential diagnosis and the lack of travel or endemic precedence.

A novel nonlinear car-following model.

The mathematical models used to describe the dynamical behavior of a group of road vehicles traveling in a single lane without overtaking are known as car-following models. These models are widely used in many commercially available microscopic traffic simulation software packages. They attempt to mimic the interactions between individual vehicles that are traveling sufficiently close together for the behavior of each vehicle to be dependent upon the motion of the vehicle immediately in front.
