Primary immune deficiency diseases (PIDDs) are a group of severe genetically determined caused by disorder the immunity links: humoral and cell-mediated links, phagocytosis, complement system. PIDDs characterized atypical recurrent infections, as well autoimmune oncological processes. In case clinical symptoms, skin manifestations in allow to suspect presence congenital disorders immunity. Ther...

We examine the effects of different latency penalties in the evaluation of push notification systems, as operationalized in the TREC 2015 Microblog track evaluation. The purpose of this study is to inform the design of metrics for the TREC 2016 Real-Time Summarization track, which is largely modeled after the TREC 2015 evaluation design.

OBJECTIVES IL-2 therapy increases memory and naive CD4 T cells in HIV-infected patients, but its effect on thymopoiesis is unknown. To investigate this effect, we quantified T-cell receptor rearrangement excision circles (TREC) in CD4 T cells from lymphopenic AIDS patients treated with highly active antiretroviral therapy and IL-2. METHODS CD4 cell subsets were evaluated by flow cytometry usi...

Past TREC experiments by the University of Massachusetts have focused primarily on ad-hoc query creation. Substantial eeort was directed towards automatically translating TREC topics into queries, using a set of simple heuristics and query expansion. Less emphasis was placed on the routing task, although results were generally good. The Spanish experiments in TREC-3 concentrated on simple index...

All of the results we report in this paper follow from straightforwardapplications of base-level CLARIT processing, utilizing essentially the same CLARIT components that were employed in the CLARIT–TREC1 system. The general improvements we observe in CLARIT–TREC-2 processing are attributable tomodifications (especially simplifications) in processing steps and in the settings of system variables...

We describe a new technique for building a relevance judgment list (qrels) for TREC test collections with no human intervention. For each TREC topic, a set of new queries is automatically generated from key phrases extracted from the top k documents retrieved from 12 different Terrier weighting models when the initial TREC topic is submitted. We assign a score to each key phrase based on its si...

This paper addresses the blog distillation problem, that is, given a user query find the blogs that are most related to the query topic. We model each post as evidence of the relevance of a blog to the query, and use aggregation methods like Ordered Weighted Averaging operators to combine the evidence. We show that using only highly relevant evidence (posts) for each blog can result in an effec...
