In 1954 Aldrich, Steinberg and Campbell described a family, originally of Dutch extraction, in which the male infants were liable to die at a young age having shown signs of 'draining ears, eczematoid dermatitis and bloody diarrhoea' from the age of a few weeks. They briefly described the clinical features in one child who was a member of this family and who died. They went on to show quite cle...

In this paper we are presenting a Half-Subtractor using Adaptive Voltage Level (AVL) technique consuming less power than the conventional one .The main objective is to design that half subtractor using either of the two adaptive voltage level(AVL) techniques to reduce the sub threshold leakage current which plays a very important role in the reduction of power dissipation. We can bring down the...

Clock gating is a predominant technique used for power saving. It is observed that the commonly used synthesis-based gating still leaves a large amount of redundant clock pulses. Data-driven gating aims to disable these. To reduce the hardware overhead involved, flip-flops (FFs) are grouped so that they share a common clock enabling signal. The question of what is the group size maximizing the ...

THISSELECTIVE BIBLIOGRAPHY concentrates on the Library Bill of Rights but also deals more broadly with intellectual freedom. The cited items are not intended to be comprehensive but rather a starting point for those interested in further reading on the topic. The title American Library Association Bulletin is used consistently to refer to all variants of the title of the periodical which it rep...

Stellar evolution models of stars of 1.45 to 3.0M have been calculated including the atomic di usion of metals and radiative accelerations for all species in the OPAL opacities. As the abundances change, the opacities and radiative accelerations are continuously recalculated during evolution. These models develop iron peak convection zones centered at a temperature of approximately 200 000K. If...
