This paper presents our Complex Answer PAragraph Retrieval (CAPAR) system designed for our participation in the TREC Complex Answer Retrieval (CAR) track. Because we were provided with a massive training set consisting of complex questions as well as the paragraphs that answered each aspect of the complex question, we cast the paragraph ranking as a learning to rank (L2R) problem, such that we ...

This study summarizes the overall solution and sub-systems developed by the Center for Robust Speech Systems (CRSS) at the University of Texas at Dallas to address the NIST LRE-2011 competition. CRSS-UTD employs five core sub-systems in the proposed language ID solution that include: (1) i-vector, (2) SVM-GSV, (3) PPRLM, (4) Articulatory Feature based, and (5) Prosody based. The first four repr...

In this paper, we describe the system designed for the TREC 2017 Precision Medicine track by the University of Texas at Dallas (UTD) Human Language Technology Research Institute (HLTRI). Our system incorporates an aspect-based retrieval paradigm wherein each of the four structured components of the topic is cast as a separate aspect, along with two “hidden” aspects encoding the need that retrie...

The aim of this study was to evaluate the importance rechecking fetal kidneys at a routine third-trimester growth scans, even if they were reported as normal during second trimester anomaly scan. Patients diagnosed with renal abnormalities for first time seen between April 2017 September 2020, retrospectively identified from obstetric database. Cases where abnormal scan, excluded study. In all ...

An analysis of plane wave scattering from a finite 1-D periodic penetrable screen is presented with the aim of demonstrating the effectiveness and the accuracy of high frequency asymptotic solutions when combined with approximate homogeneous transition boundary conditions. The results of the numerical investigation are relevant to the electromagnetic scattering from a large planar semi-transpar...

OBJECTIVE To determine the reasons adolescents are not vaccinated for specific vaccines and how these reasons have changed over time. METHODS We analyzed the 2008-2010 National Immunization Survey of Teens examining reasons parents do not have their teens immunized. Parents whose teens were not up to date (Not-UTD) for Tdap/Td and MCV4 were asked the main reason they were not vaccinated. Pare...

CONTEXT Vaccination coverage rates can be improved through the application of complete and accurate immunization information systems (IISs). OBJECTIVE Evaluate the completeness and accuracy of Wisconsin's IIS, the Wisconsin Immunization Registry (WIR). DESIGN Cross-sectional evaluation, comparing vaccination medical records (MRs) from provider clinics with WIR records. PARTICIPANTS Medica...
