OBJECTIVE To characterize deficits in nonverbal recognition memory and functional brain changes associated with these deficits in Alzheimer disease (AD). METHODS Using O-15 PET, we studied 11 patients with AD and 17 cognitively intact elders during the combined encoding and retrieval periods of a nonverbal recognition task. Both task conditions involved recognition of line drawings of abstrac...

People's memory for new information can be enhanced by cuing them to forget older information, as is shown in list-method directed forgetting (LMDF). In this task, people are cued to forget a previously studied list of items (list 1) and to learn a new list of items (list 2) instead. Such cuing typically enhances memory for the list 2 items and reduces memory for the list 1 items, which reflect...

This paper describes our participation in the Entity List Completion (ELC) task at Entity track 2011. Our approach combined the work done for the Related Entity Finding 2010 task with some new criteria as the proximity or the similarity between a candidate answer with the correct answers given as examples or their cooccurrences.

We describe our participation in the TREC-10 Question Answering track. All our runs used the Tequesta system; we provide a detailed account of the natural language processing and inferencing techniques that are part of Tequesta. We also summarize and discuss our results, which concern both the main task and the list task.

An ABA'B design was used to evaluate the effects of choice on task engagement for 3 adults who had been diagnosed with traumatic brain injury. A yoked-control condition, in which tasks that were selected by each participant were assigned subsequently to that participant by a trainer, was implemented to help distinguish between the effects of task preference and choice. The results for all 3 par...

This paper presents an approach on a querybiased document summarisation and an evaluation of the use of such an approach for question answering tasks. We observed a significant difference in the user’s performance by presenting a list of documents customized to the task type, compared with a generic document summarization approach. This indicates that paying attention to the task and the search...

This deliverable describes the task-level optimization libraries designed for the ACOTES tool chain. Based on the polyhedral model of compilation, these libraries support automatic parallelization and adaptation of thread-level parallelism to a target. The libraries can also be applied to loop nest optimization of single-threaded code. Early experimental validation is described in the document,...
