Phase convergence to within lOin mechanically generated waves was achieved at a specified point in a wave flume by frequency focusing. Owing to the presence of nonlinear waves, the crest elevation reaches a maximum somewhat further from the waveboard, where also breaking occurs if the waves are of sufficient size. The critical amplitude for breaking was not in close agreement with previous meas...

Alexia is usually seen after ischaemic insults to the dominant parietal lobe. A patient is described with a particular alexia to reading Hebrew (right to left), whereas no alexia was noted when reading in English. This deficit evolved after a hypertensive right occipitoparietal intracerebral haemorrhage, and resolved gradually over the ensuing year as the haematoma was resorbed. The deficit sug...

Cadmium selenide nanorods, unique nanostructures which possess bright and up to 100% polarized photoluminescence, now can be arranged unidirectionally in a single line. The method is based on the chemical attachment of nanorods to the surface of a single cleaved semiconductor nanolayer and exploits a combination of wet-chemical and epitaxial growth techniques to produce templated semiconductor ...

There is growing interest in providing multimedia and broadband access over satellites. However there are several technical challenges need to be addressed. One challenge is security in terms of understanding threats and providing an effective security system. Also this paper presents a ULE security solution using ULE mandatory extension headers. The design issues and choices are discussed. The...
