New cardiovascular risk factors exist, but are they clinically useful?
There is substantial interest in identifying new risk factors for cardiovascular disease, to improve our understanding of disease biology and to account for the cases of heart disease that cannot be explained by known risk factors.

متن کاملPrimordial Black Holes: Do They Exist and Are They Useful?
Recent developments in the study of primordial black holes (PBHs) are reviewed, with particular emphasis on their formation and evaporation. It is still not clear whether PBHs formed but, if they did, they could provide a unique probe of the early Universe, gravitational collapse, high energy physics and quantum gravity. Indeed their study may place interesting constraints on the physics releva...
متن کاملRacial/ethnic differences in infant mortality attributable to birth defects by gestational age.
OBJECTIVE Birth defects are a leading cause of infant mortality in the United States. Previous reports have highlighted black-white differences in overall infant mortality and infant mortality attributable to birth defects (IMBD). We evaluated the impact of gestational age on US racial/ethnic differences in IMBD. METHODS We estimated the rate of IMBD as the underlying cause of death using the...
متن کاملMultiprocessor Architectures Don ’ t Really Exist ( But They Should )
Multiprocessors and high-level concurrent languages generally provide only relaxed (non-sequentiallyconsistent) memory models, to permit performance optimisations. One has to understand these models to program reliable concurrent systems but, despite work in this area over many years, the specifications of real-world multiprocessors and languages are typically ambiguous and incomplete informal-...

The stability of racial and ethnic differences in cortisol levels over time is not well understood, and additional research is needed to establish racial and ethnic differences in psychosocial stress levels as related to changes in...
