It has been recently shown that in rat liver there are two enzymes which phosphorylate glucose to glucose 6-phosphate. One of them is a hexokinase with a great affinity for glucose and, like those of other animal tissues it is inhibited by glucose 6phosphate; the other one, named glucokinase, has a low affinity for glucose, is not inhibited by glucose 6phosphate, and appears to be responsible f...

Pfaffian Hybrid Systems. Pfaffian hybrid systems, which we recently introduced in [18], are a sub-class of o-minimal hybrid systems which capture rich continuous dynamics and yet can be studied using finite bisimulations. In particular Pfaffian hybrid systems include hybrid systems with continuous dynamics definable by functions such as exp, sin, cos, and other trigonometric functions in approp...

The sand cat captive-breeding program at the Breeding Centre for Endangered Arabian Wildlife in Sharjah, UAE, has until recently been severely compromised by very high newborn mortality rates.
