This short course will present the state-of-the-art in understanding RF power phenomena that detrimentally affect space, aircraft and terrestrial communications. Dramatic increase in communications capacity, bandwidth, number of carriers and antennas poses new challenges in handling the high RF power. These problems become ever more acute and critical for emerging and future RF systems. The sho...
PRIMARY cerebral amyloidosis is characterized by deposition of amyloid within the cerebral tissue (e.g., core of neuritic plaques and core of plaques in spongiform encephalopathies) and the cerebral and meningeal blood vessel walls (amyloid or congophilic angiopathy) in the absence of systemic amyloidosis. Primary cerebral amyloidosis has been associated with normal brain aging changes" and wit...
The concept of physiological time was introduced by Hill ( 1951)). He reasoned that as metabolic rate and longevity change with body size, time itself may be scaled. Hence, spans such as growth to maturity, gestation period and the time required for digestion transpire on a time scale dependent upon the body size of an animal. Since Hill’ s hypothesis, many of these rate variables have been exa...
amMannitol was produced as an end product when resting cell suspensions of strains of Sl~rptococ~s mutcms were given high levels of sucrose or glucose. The presence of mannitol in the supernatant from glucose incubated cells and the occasional detection of mannitol-lphosphate suggest that mannitol was formed by a reduction of fructose-6-phosphate. This pathway would permit the regeneration of N...
Lupus anticoagulants are circulating autoantibodies, primarily directed against phospholipids, that prolong the partial thromboplastin time. They have been previously associated with systemic arterial and venous thrombosis and arterial stroke, but not with cerebral venous thrombosis. We describe 2 young patients with cerebral venous thrombosis documented by intravenous digital subtraction angio...
This paper reviews the state of the art channel coding techniques for ultra-reliable low latency communication (URLLC). The stringent requirements of URLLC services, such as ultra-high reliability and low latency, have made it the most challenging feature of the fifth generation (5G) mobile systems. The problem is even more challenging for the services beyond the 5G promise, such as tele-surger...
All the review papers and the short communications presented in this session are in this EAAP publication entitled “Indicators of milk and beef quality”. Additional papers from invited authors were written in 2004 and then added to complete the publication although not all topics related to quality indicators are covered in the present publication. Review papers aim to describe the state of the...
Using x-ray photon correlation spectroscopy, we studied the dynamics in the nematic phase of a nanorod suspension. The collective diffusion coefficient in the plane perpendicular to the director varies sharply with the wave vector. Combining the structure factor and the diffusion coefficient, we find that the hydrodynamic function of the phase decreases by more than a factor of 10 when going fr...
Hanc:iedness is the most obvious aspect of thc laleralization of the human brain, and most studies on cerebral asymmctrics in humans have been concerned with this topic. As a consequence, many experiments dealing with potential functional lateralizations in animals deal with the putative analogue to human handed ness, namely forelimb preferences (Denenberg 1981). These studies indicate that lim...
Over the last decade, we have witnessed the rapid evolution of Multiple-Input Multiple-Output (MIMO) systems which promise to break the frontiers of conventional architectures and deliver high throughput by employing more than one element at the transmitter (Tx) and receiver (Rx) in order to exploit the spatial domain. This is achieved by transmitting simultaneous data streams from different el...
