The census of open clusters in the Milky Way is a never-before seen state flux. Recent works have reported hundreds new thanks to incredible astrometric quality Gaia satellite, but other also that many discovered pre era may be associations. We aim conduct comparison clustering algorithms used detect clusters, attempting statistically quantify their strengths and weaknesses by deriving sensitiv...

BACKGROUND The ability to accurately forecast census counts in hospital departments has considerable implications for hospital resource allocation. In recent years several different methods have been proposed forecasting census counts, however many of these approaches do not use available patient-specific information. METHODS In this paper we present an ensemble-based methodology for forecast...

BACKGROUND The regulation of alcohol outlet density has been considered as a potential means of reducing alcohol consumption and related harms among underage youth. Whereas prior studies have examined whether alcohol outlet density was associated with an individual's alcohol consumption and related harms, this study examines whether it is related to the co-occurrence, or clustering, of these be...

BACKGROUND Studies involving the built environment have typically relied on US Census data to measure residential density. However, census geographic units are often unsuited to health-related research, especially in rural areas where development is clustered and discontinuous. OBJECTIVE We evaluated the accuracy of both standard census methods and alternative GIS-based methods to measure rur...

Africa continues to lack the data for direct estimates of infant and child mortality. Estimation of infant and child mortality in Africa has been based on Brass-type indirect methods. This paper seeks to utilise an extension of the Brass method proposed by Preston and Palloni—known as the “own-child” method— to estimate infant and child mortality using the 1990 Zambia national census data. The ...

In this study, we analyzed all known protein sequences for repeating amino acid segments. Although duplicated sequence segments occur in 14 % of all proteins, eukaryotic proteins are three times more likely to have internal repeats than prokaryotic proteins. After clustering the repetitive sequence segments into families, we find repeats from eukaryotic proteins have little similarity with prok...

Over the past 20 years, more than 78,000 16S rRNA gene sequences have been deposited in GenBank and the Ribosomal Database Project, making the 16S rRNA gene the most widely studied gene for reconstructing bacterial phylogeny. While there is a general appreciation that these sequences are largely unique and derived from diverse species of bacteria, there has not been a quantitative attempt to de...
