Outcomes of patients transferred to the University of Michigan health system on a short-term ventricular assist device for cardiogenic shock
<p>Short-term ventricular assist devices (VADs) are mechanical pumps that are used to temporarily support a patient who is in cardiogenic shock. These VADs are effective in sustaining a patient’s life until he or she can been transferred to a tertiary cardiac center such as the University of …

Permanent Coexistence for Omnivory Models
… of concern in mathematical biology is the long-term survival of each species in a set of populations. This question is particularly puzzling for a natural system with omnivory due to the fact that simple mathematical models of omnivory are prone to species extinction. Omnivory is defined as …
