In the fifty years since the first atomic structure of a protein was revealed, tens of thousands of additional structures have been solved. Like all objects in biology, proteins structures show common patterns that seem to define family relationships. Classification of proteins structures, which started in the 1970s with about a dozen structures, has continued with increasing enthusiasm, leadin...

Introduction: Taxonomic classification of asteroids based on their visible / near-ir spectra or multi band photometry has proven to be a useful tool to infer other properties about asteroids. Meteorite analogs have been identified for several taxonomic classes, permitting detailed inference about asteroid composition [1], [2]. Trends have been identified between taxonomy and measured asteroid d...

This paper provides an empirical analysis of risk handling arrangements adopted in the relationship between the venture capital investor and his investee. The theoretical framework adopted is principal-agent analysis, which views the investee as a risk averse agent entering into a risk sharing contract with the investor, a risk neutral (fully diversified) principal. The sample analysed is made ...

Reversible logic is one of the new paradigms for power optimization that can be used instead of the current circuits. Moreover, the fault-tolerance capability in the form of error detection or error correction is a vital aspect for current processing systems. In this paper, as the multiplication is an important operation in computing systems, some novel reversible multiplier designs are propose...
