OBJECTIVE We sought to quantify agreement between Institute of Medicine (IOM) and Department of Health and Human Services (DHHS) retention indicators, which have not been compared in the same population, and assess clinical retention within the largest HIV cohort collaboration in the U.S. DESIGN Observational study from 2008-2010, using clinical cohort data in the North American AIDS Cohort C...

Animals with compact sensory systems face an encoding problem where a small number of sensory neurons are required to encode information about its surrounding complex environment. Using Caenorhabditis elegans worms as a model, we ask how chemical stimuli are encoded by a small and highly connected sensory system. We first generated a comprehensive library of transgenic worms where each animal e...

An indicator dilution method for measuring oscillatory flow in a vessel is analyzed in terms of a mixing chamber with a constant volume. For the correct measurement of mean flow, the time constant of detection of the indicator Should be very much shorter than the shortest time constant of the mixing volume. The performance of such a system was examined with a thermal indicator. Although the app...

Introduction A number of authors have investigated associations between MR vascular parameters and traditional histopathological prognostic markers. Results have varied with some studies revealing correlations while others have failed to find any associations. The aim of this work was to determine if there were any associations not only between pretreatment MR derived vascular parameters and hi...

Paper presents scientometry as a science and a fundamental instrument for determining the international value of an university as well as for the statistical evaluation of scientific research results. The impact of the research measurable through scientometric indicators is analyzed. Promoting the scientific production of universities through institutional digital repositories deals with the co...

Mouse head-fixed behaviour coupled with functional imaging has become a powerful technique in rodent systems neuroscience. However, training mice can be time consuming and is potentially stressful for animals. Here we report a fully automated, open source, self-initiated head-fixation system for mesoscopic functional imaging in mice. The system supports five mice at a time and requires minimal ...

An index is proposed that is based on the h-index and a 3-year publication/citation window. When updated regularly, it shows the current scientific performance of researchers rather than their life-time achievement as indicated by common scientometric indicators. In this respect, the new rating scheme resembles established sports ratings such as in chess or tennis. By the example of ACM SIGMOD ...

background: social health is important to be assessed as a dimension of health. in this study we tried to determine areas and sub-areas of children social health indicators.   methods: in a structured way, we reviewed the main social health databases and documents since 1995, both iranian and international were reviewed to develop conceptual framework and to extract indicators.   results: accor...

OBJECTIVE To explore the potential for using seven prescribing indicators, individually and in combination, to measure prescribing quality for hospitalised psychiatric patients. DESIGN AND SETTING The dataset included full details of all psychotropic medication prescribed over a 24 hour period to 4192 inpatients in 49 British mental health services in 1998. RESULTS Despite the large size of...
