Deadlock is an undesired situation in multithreaded software since it can lead to the stoppage of software.This paper studies the problem of deadlock control of multithreaded software based on Gadara nets, which are well studied for modelling concurrent programs.In particular, an iterative deadlock prevention policy based on siphons is proposed for
Conduction velocity is the speed at which electrical signals travel along axons and is a crucial determinant of neural communication.Inferences about conduction velocity can now be made in vivo in humans using a measure called the magnetic resonance (MR) g-ratio.This is the ratio of the inner axon diameter relative to that of the axon plus the myel
Abstract Introduction This resource contains a medical simulation in which a 42-year-old male smoker undergoing a T7-T8 laminectomy and fusion in the prone position suddenly develops complete airway obstruction shortly after dissection has begun.This case provides an opportunity to discuss the risks associated with prone positioning, management of
