Methods for discerning and measuring Kolmogorov Complexity are discussed and their relationships explored. A computationally efficient method of using Lempel Ziv 78 Universal compression algorithm to estimate complexity is introduced. 1 Abstract—Methods for discerning and measuring Kolmogorov Complexity are discussed and their relationships explored. A computationally efficient method of using ...

BACKGROUND We examined practice patterns of inpatient testing to identify stroke etiologies and treatable risk factors for acute ischemic stroke recurrence. METHODS AND RESULTS We identified stroke cases and related diagnostic testing from four 1-year study periods (July 1993 to June 1994, 1999, 2005, and 2010) of the Greater Cincinnati/Northern Kentucky Stroke Study. Patients aged ≥18 years ...

BACKGROUND Spirometry reference values are important for the interpretation of spirometry results. Reference values should be updated regularly, derived from a population as similar to the population for which they are to be used and span across all ages. Such spirometry reference equations are currently lacking for central European populations. OBJECTIVE To develop spirometry reference equat...

BACKGROUND/AIMS Central auditory function can be studied to monitor the progression of mild cognitive impairment to dementia. Our aim was to address this issue in a prospective longitudinal setting. METHODS Tests of central hearing function were performed on 70 subjects with either Alzheimer's disease (AD) or mild cognitive impairment, and in controls with subjective memory complaints but nor...

Our understanding of basic evolutionary processes in bacteria is still very limited. For example, multiple recent dating estimates are based on a universal inter-species molecular clock rate, but that rate was calibrated using estimates of geological dates that are no longer accepted. We therefore estimated the short-term rates of mutation and recombination in Helicobacter pylori by sequencing ...

OBJECTIVE This report presents data on the prevalence of oral sex with opposite-sex partners and the timing of first oral sex relative to first vaginal intercourse among females and males aged 15-24 based on the National Survey of Family Growth (NSFG) data from 2007-2010. The question on timing, added to the NSFG in 2007, asked females and males whether first oral sex occurred before, after, or...
