The World Health Organization (WHO), National Cholesterol Education Program Adults Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF) have proposed different criteria to diagnose metabolic syndrome (MetS). However, there is no single definition to accurately diagnose MetS. The objective of this study is to estimate the prevalence of MetS using WHO, NCEP ATP III and I...
UNLABELLED We report a new microcirculatory assessment device, the Braedius Cytocam, an Incident Dark Field (IDF) video microscope, and compare it with a precursor device utilising side stream dark field (SDF) imaging. METHODS Time matched measurements were made with both devices from the sublingual microcirculation of pigs subjected to traumatic injury and hemorrhagic shock at baseline and d...
TF-IDF is one of the most popular term-weighting schemes, and is applied by search engines, recommender systems, and user modeling engines. With regard to user modeling and recommender systems, we see two shortcomings of TF-IDF. First, calculating IDF requires access to the document corpus from which recommendations are made. Such access is not always given in a user-modeling or recommender sys...
BACKGROUND The American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), revising the National Cholesterol Evaluation Program for Adult Treatment Panel III (NCEP ATP III), and the International Diabetes Federation (IDF) have proposed definitions of metabolic syndrome that take into account waist circumference thresholds according to ethnicity. In this study we estimated ...
With the increased popularity of replica-based services in distributed systems such as the Grid, consistency control among replicas becomes more and more important. To this end, IDF (Inconsistency Detection Framework), a two-layered overlay-based architecture, has been proposed as a new way to solve this problem—instead of enforcing a predefined protocol, IDF detects inconsistency in a timely m...
The tf-idf is an algorithm which is generally used where massive data processing is done. Tf-idf is the weight given to a particular term within a document and it is proportional to the importance of the term. This paper aims to use the idea behind the tf-idf algorithm to design the df-icf algorithm which finds the importance of a particular document within the given corpus. General Terms DF-IC...
Objectives of this review are to define criteria for evaluating insoluble dietary fiber (IDF) methods, discuss their relevance in meeting the nutritional needs of ruminants and herbivores, describe problems with empirical IDF methods, and assess their relative merits. The challenge for the researcher, nutritionist, and analyst is to select fiber methods that are relevant and reproducible. Witho...
INTRODUCTION Full text searching over a database of moderate size often uses the inverse document frequency, idf = log(N/df), as a component in term weighting functions used for document indexing and retrieval. However, in very large databases (e.g. internet search engines), there is the potential that the collection size (N) could dominate the idf value, decreasing the usefulness of idf as a t...
