On Sunday, April 12, 2009, Steven A. Huesing passed away. Since 1997 Steven Huesing was Executive Director of IMIA the International Medical Informatics Association [1]. In this prominent role he provided for many years signif icant and global contributions to the progress of our f ield. It was through his tireless work that IMIA has developed into the leading international association that it ...

Open Source Software (contrasted with proprietary or “closed” software) has become a more widely accepted enterprise solution not withstanding some issues related to intellectual property rights and issues of liability and indemnification. Open Source Software (OSS) takes collaborative software development to a global extreme – OSS also provides a mechanism for decreasing time-to-market, improv...

scientific communications network is presented in, sociology of science. and we can use steven's evaluative bibliometrics to map it. in citation network approach, scientist's communication behavior is predicted through their citation behavior. in this paper, first, concepts such as sociology of science, scientific community, scientific communications and its kinds are described. two k...

Using methods developed by Coons and Tyler, we give a new proof of a recent result of Defant, by determining the maximal order of the number of hyper-(b-ary)expansions of a nonnegative integer n for general integral bases b > 2.

How do computer architectures and physical architectures inform each other? This talk will explore the interconnection of data and visualization through an architectural and computational lens over the last 50 years, including the work of Steven Coons, Christopher Alexander, Richard Saul Wurman and others. Speaker Bio Molly Wright Steenson is an associate professor at the Carnegie Mellon School...

In a previous work [4] we found a relation between the ranks of codiagonal matrices (matrices with 0's in their diagonal and non-zeroes elsewhere) and the quality of explicit Ramsey-graph constructions. We also gave there a construction based on the BBR-polynomial of Barrington, Beigel and Rudich [1]. In the present work we give another construction for low-rank co-diagonal matrices, based on a...

We prove that, somewhat surprisingly, there is no blackbox reduction of (poly-to-one) trapdoor functions to trapdoor predicates (equivalently, to public-key encryption schemes). Our proof follows the methodology that was introduced by Impagliazzo and Rudich [19], although we use a new, weaker model of separation.

Although chloramphenicol is known to inhibit microbial protein synthesis both in intact cells (1-3) and in cell-free systems (4--8), similar inhibition of protein synthesis does not occur in analogous mammalian systems unless large amounts of chloramphenicol are employed (9-12). The difference in sensitivity to chloramphenicol is most striking in cell-free systems, where cellular permeability i...
