The US National Cancer Institute Gastrointestinal Intergroup has contributed to the development of chemotherapy and radiation regimens for the treatment of stage II and III rectal cancer. The first Intergroup trial demonstrated improvement in relapse-free and overall survival for patients who received protracted venous infusion fluorouracil (5-FU) with radiation compared to those treated with b...

To combine information from heterogeneous sources, equivalent data in the multiple sources must be identified. This task is the field matching problem. Specifically, the task is to determine whether or not two syntactic values are alternative designations of the same semantic entity. For example the addresses Dept. of Conaput. Sci. and Eng., University of California, San T&m. 91;oo G’ilmnn Dr. ...

We initiate the investigation of a new kind of e ciency for cryptographic transformations. The idea is that having once applied the transformation to some documentM , the time to update the result upon modi cation of M should be \proportional" to the \amount of modi cation" done to M . Thereby one obtains much faster cryptographic primitives for environments where closely related documents are ...

Enteropathogenic Escherichia coli (EPEC) infection is not generally thought to cause severe diarrhoea after the neonatal period. Patients admitted to Queen Elizabeth Hospital for Children over the three years (1984-7) with diarrhoea and EPEC infection were reviewed. Clinical details, features of small intestinal mucosa, and treatment were recorded in those who developed chronic diarrhoea with f...

A number of possible approaches to automatic memory management in C++ have been considered over the years. Here we propose the reconsideration of an approach that relies on partially conservative garbage collection. Its principal advantage is that objects referenced by ordinary pointers may be garbage-collected. Unlike other approaches, this makes it possible to garbage-collect objects allocate...

In order for learning to improve the adaptiveness of an animal's behavior and thus direct evolution in the way Baldwin suggested, the learning mechanism must incorporate an innate evaluation of how the animal's actions in uence its reproductive tness. For example, many circumstances that damage an animal, or otherwise reduce its tness are painful and tend to be avoided. We refer to the mechanis...

At the Computer Systems Laboratory at UCSD, we conduct research in distributed systems, operating systems, network protocols, and performance evaluation. This document reviews the current research within the Computer Systems Laboratory. There are four sections which describe the work of the four groups within the laboratory: Decentralized Control Research Group; Operating Systems Research Group...

Computational Grids, composed of distributed and often heterogeneous computing resources, have become the platform-of-choice for many performance-challenged applications. Proof-of-concept implementations have demonstrated that both Grids and clustered environments have the potential to provide great performance bene ts to distributed resource-intensive applications. However, at the present time...

Missing metastases, also called vanishing or disappearing liver metastases, concern about 5% of patients with colorectal liver metastasis undergoing chemotherapy, and this phenomenon is likely to become more frequent in the near future, with the widespread use of highly efficient chemotherapy. As their definition is highly dependent on the quality of initial imaging, a DLM on preoperative compu...
