This change proposal speci es the addition of tables with valid-time support into SQL/Temporal, and explains how to use these facilities to migrate smoothly from a conventional relational system to a temporal system. Initially, important requirements to a temporal system that may facilitate such a transition are motivated and discussed. The proposal then describes the language additions necessa...

The O157:H7 clone of Escherichia coli, which causes major, often prolonged outbreaks of gastroenteritis with hemolytic-uremic syndrome (HUS) such as those in Japan, Scotland, and the United States recently, is thought to be resident normally in cattle or other domestic animals. This clone is of major significance for public health and the food industry. We have developed a fast method for seque...

The neuropsychological concepts found in Donald Hebb's The Organization of Behavior have greatly influenced many aspects of neuroscience research over the last half century. Hebb's ideas arose from a rich tradition of research. An underappreciated contribution came from pioneering studies at Yale University. Here, we wish to reconsider these developments, placing particular emphasis on the role...

Plant O-methyltransferases (OMTs) play important roles in secondary metabolism. Two clusters of genes coding for caffeic acid OMT (COMT) have been identified in the apple genome. Three genes from one cluster and two genes from another cluster were isolated. These five genes encoding COMT, designated Mdomt1-Mdomt5 (GenBank accession nos. DQ886018-DQ886022), were distinguished by a (CT)(n) micros...

Division of labor is a complex phenomenon observed throughout nature. Theoretical studies have focused either on its emergence through selforganization mechanisms or on its adaptive consequences. We suggest that the interaction of self-organization, which undoubtedly characterizes division of labor in social insects, and evolution should be further explored. We review the factors empirically sh...

This paper describes the Organization-based Multiagent System Engineering (O MaSE) Process Framework, which helps process engineers define custom multiagent systems development processes. OMaSE builds off the MaSE methodology and is adapted from the OPEN Process Framework (OPF). OPF implements a Method Engineering approach to process construction. The goal of O-MaSE is to allow designers to cre...
