Spinal serotonin is derived entirely from bulbar sources and plays an important role in spinal modulatory processes, including pain modulation. Establishing the electrophysiological properties of SEROTONERGIC bulbospinal neurons in the pontomedullary raphe and reticular formation is critical to understanding the physiological role of serotonin in the spinal cord. Neurons were characterized by t...

One may postulate that man’s interest in fish emerged as soon as he was able to express his thoughts and notions as fish, among other animals, were subject of early communications. These were transmitted first by drawings, later by inscriptions and in writings. It was but much later that fishes began to occupy man’s interest as objects of science. Aristotle’s treatises on “History of Animals” i...

background: major depression is a common disorder with great social and individual burdens. transcranial sonography (tcs) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. the brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. in this study we compared the echogenicity of the raphe n...

Approximate resolution of linear systems of differential equationswith varying coefficients is a recurrent problem, shared by a number of scientific and engineering areas, ranging from QuantumMechanics to Control Theory. When formulated in operator or matrix form, the Magnus expansion furnishes an elegant setting to build up approximate exponential representations of the solution of the system....

In this dissertation we address shortcomings of two important group communication layers, IP Multicast and gossip based message dissemination, both of which have scalability issues when the number of groups grows. We propose a transparent and backward-compatible layer called Dr. Mul-ticast to allow data center administrators to enable IPMC for large numbers of groups without causing stability i...
