The trend in information retrieval systems is from document to sub-document retrieval, such as sentences in a summarization system and words or phrases in question-answering system. Despite this trend, systems continue to model language at a document level using the inverse document frequency (IDF). In this paper, we compare and contrast IDF with inverse sentence frequency (ISF) and inverse ter...

We utilized gas-phase diffusion flame synthesis, which has potential for large-scale production of metal oxide nanoparticles, to produce iron oxide nanoparticles (IONPs) with variable oxidation states. The efficacy of these materials in removal of arsenate (As(V) ) from water was assessed. Two different flame configurations, a diffusion flame (DF) and an inverse diffusion flame (IDF), were empl...

OBJECTIVE The International Diabetes Federation (IDF) has recently established a worldwide consensus definition of the metabolic syndrome. No prospective data are available on the cardiovascular risk associated with this new metabolic syndrome definition. RESEARCH DESIGN AND METHODS In a prospective study of 750 coronary patients, we recorded vascular events over 4 years. RESULTS From our p...

BACKGROUND The International Diabetes Federation (IDF) published a new definition of the metabolic syndrome (MetS). For this definition we compared frequency, concordance, clinical and laboratory stigmata and carotid atherosclerosis with those of the established definitions by the National Cholesterol Education Program (NCEP) and World Health Organization (WHO). MATERIALS AND METHODS A total ...

BACKGROUND The 2005 International Diabetes Federation (IDF) definition of the metabolic syndrome was designed to be useful worldwide, but to date few prevalence studies have used that definition in European populations. We estimated the age- and sex-stratified prevalence of IDF-defined metabolic syndrome in a county of Norway and compared it with the prevalence estimated using the revised Natio...

OBJECTIVES The goal was to clarify if insulin resistance (IR) would predict cardiovascular disease (CVD) independent of the metabolic syndrome (MetSyn). BACKGROUND Although the cause of MetSyn is not well defined, IR has been proposed to be an important cause. Only a small number of population-based studies have sought to clarify if IR predicts CVD independent of MetSyn. METHODS This was a ...

The metabolic syndrome is associated with increased cardiovascular morbidity and mortality (1,2). In 2005, the International Diabetes Federation (IDF) formulated a new, clinically accessible worldwide definition of the metabolic syndrome in a global consensus statement (3) built on earlier definitions (4,5). According to the IDF, central obesity is an essential component of the metabolic syndro...

BACKGROUND The Israel Defense Forces Medical Corps (IDF MC) institutional review board (IRB) is one of approximately 50 IRBs active in Israel. In addition to routine IRB considerations it must also address in its deliberations specific safeguards in place in the IDF to protect research volunteers in the military environment. In this report, we present the characteristics of the IDF IRB, includi...

Most of the traditional recommendation algorithms are based on TF-IDF, a term-based weighting method. This paper proposes a new method for recommending news items based on the weighting of the occurrences of references to concepts, which we call Concept Frequency-Inverse Document Frequency (CFIDF). In an experimental setup we apply CF-IDF to a set of newswires in which we detect 1, 167 instance...
