UNIX system security today often relies on cor rect operation of numerous privileged subsystems and careful attention by expert system administra tors In the context of global and possibly hostile networks these traditional UNIX weaknesses raise a legitimate question about whether UNIX systems are appropriate platforms for processing and safe guarding important information resources Domain and ...

The fundamental challenge for human-computer interaction (HCI) is to invent and design a culture in which humans can express themselves and engage in personally meaningful activities. Cultures are substantially defined by their media and tools for thinking, working, learning, and collaborating. New media change (1) the structure and contents of our interests, (2) the nature of our cognitive and...

description and bibliographic detail for individual items, as in her entry for a short treatise on urines that provides specific directions for investigation of possible Latin sources. In another instance, she warns readers when a text is misrepresented by its title (i.e., 'dieta ypocras' in MS R.14.32 [5]) and then cross-references other manuscripts in the handlist where the same title accurat...

MDMA (3,4-methylenedioxymethamphetamine), popularly known as “Ecstasy,” was first introduced and patented by Merck & Co., Inc., in 1914 as an appetite suppressant. Currently, its primary role is as an illegal stimulant used to produce a euphoric effect during parties. This case report de scribes a 31-year-old man who, after taking 3 tablets of Ecstasy, presented to an emergency department with ...

In the previous scribes, we introduced general objects used in graphical models as well message passing schemes such as the sum-product algorithm and the max-sum algorithm for efficient computation of local marginals over subsets of the graph as well as the most probable state of the graph. For graphs which are trees, we noted that the algorithms are exact. In this article, we discuss a more fl...

Genes are propagated by error-prone copying, and the resulting variation provides the basis for phylogenetic reconstruction of evolutionary relationships. Horizontal gene transfer may be superimposed on a tree-like evolutionary pattern, with some relationships better depicted as networks. The copying of manuscripts by scribes is very similar to the replication of genes, and phylogenetic inferen...
