Variceal disease and its management are of the utmost importance in the treatment of portal hypertension. Current guidelines are universal for management of variceal disease in portal hypertension. Classification and grading systems are numerous and differ according to geographical location. In this exhaustive review, the historical aspects of variceal disease, its classification and the gradin...

The world-wide use of protein-based therapeutics has increased dramatically in the past 15 years. As a result, finding more cost-effective and efficient methods of improving upstream bioprocess production is a high priority for many biopharmaceutical firms. One strategy to improve upstream production is to use bioprocessing models that mimic large scale bioreactors to help choose the most appro...

This report presents the system used by the University of Massachusetts for its participation in three of the five TDT tasks this year: detection, first story detection, and story link detection. For each task, we discuss the parameter setting approach that we used and the results of our system on the test data. In addition, we use TDT evaluation approaches to show that the tracking performance...

This paper addresses the issue of representing time entities (i.e. instants and intervals) as Linked Data, and how to exploit topological temporal relationships in order to increase the connectivity degree within Linked Data sets. Describing and efficiently managing temporal information in knowledge management systems is important. Information is volatile, dependant on a number of contexts for ...

This paper tackles the problem of timeline generation from traditional news sources. Our system builds thematic timelines for a general-domain topic defined by a user query. The system selects and ranks events relevant to the input query. Each event is represented by a one-sentence description in the output timeline. We present an inter-cluster ranking algorithm that takes events from multiple ...

In a previous paper, we showed that class of time travel paradoxes which cannot be resolved using Novikov's self-consistency conjecture can by assuming the existence multiple histories or parallel timelines. However, our proof was obtained simplistic toy model, formulated contrived laws physics. present paper define and analyze new model paradoxes, is more compatible with known This consists tr...
