Ring DNA from rat liver mitochondria has been examined by circular dichroism (CD) in the region of the 225 to 320 m/∼ and the followings have been clarified. The ring DNA gives a CD spectral curve somewhat different from linear DNA from nuclei, showing a big positive peak at 266 m/∼ and a small negative band at 243 m!∼. That is, the positive CD band of ring DNA shifted by about 7 m/∼ to the sho...

We discuss experimental results of a versatile nonbinary modulation and channel code appropriatefor two-dimentional page-oriented holographic memories. An enumerative permutation code is used to provide a modulation code that permits a simple maximum-likelihood detection scheme. Experimental results from the IBM Demon testbed are used to characterize the performance and feasibility of the propo...

We propose a visualization tool to help application developers in understand-ing/debugging the execution of event-based applications. Vizar allows applications to record and then replay executions of event-based systems. It is a general purpose visualization service. It is not intended or linked in any way to any speciic system { eventhough it was rst targeted for active databases. Also we inve...

Background Surface Topography can be used to evaluate patients with spinal deformity, especially adolescents with scoliosis in whom a reduced number of radiographic evaluations is desired. The Formetric 4D (Diers International GmbH, Schlangenbad, Germany) is a surface topography system that is able to identify anatomical landmarks and construct a 3-dimentional model of the spine using only surf...
