Comparative analyses on disease and nondisease (ND) genes have greatly facilitated the understanding of human diseases. However, most studies have grouped all the disease genes together and have performed comparative analyses with other ND genes. Thus, the molecular mechanism of disease on which disease genes can be separated into monogenic and polygenic diseases (MDs and PDs) has been ignored ...

We study systematically the higher order corrections to the parity violating part of the effective action for the Abelian Chern-Simons theory in 2+ 1 dimensions, using the method of derivative expansion. We explicitly calculate the parity violating parts of the quadratic, cubic and the quartic terms (in fields) of the effective action. We show that each of these actions can be summed, in princi...

We have investigated how structure-dependent mutation matrices derived in previous work correlate with various physical-chemical properties of the 20 naturally occurring amino acids. Among the properties we investigated were delta G of transfer from water to octanol and cyclohexane, alpha helical and beta sheet propensity, size, and charge. We found that the delta G of transfer to octanol had a...

Category ratings of stimulus intensities are affected by the skewing of frequency distributions of stimuli. According to Parducci’s theory, frequency effects are due to the tendency of participants to use all the categories with the same frequency. According to Haubensak’s theory, these effects are due to the tendency of participants to use all categories during the initial presentations. Frequ...

Injectivity of objects with respect to a set H of morphisms is an important concept of algebra and homotopy theory; here we study the logic of consequences of H, by which we understand morphisms h such that injectivity with respect to H implies injectivity with respect to h. We formulate three simple deduction rules for the injectivity logic and for its finitary version (where morphisms between...

This is an introductory exposition to background material useful to appreciate various formulations of the Mordell–Lang conjecture (now established by recent spectacular work due to Vojta, Faltings, Hrushovski, Buium, Voloch, and others). It gives an exposition of some of the elementary and standard constructions of algebro-geometric models (rather than model-theoretic ones) with applications (...

PURPOSE To establish cutoff points for the analysis of the Behavior Observation Form (BOF) of children in the ages of 2 to 23 months and evaluate the sensitivity and specificity by age group and domains (Emission, Reception, and Cognitive Aspects of Language). METHODS The sample consisted of 752 children who underwent BOF. Each child was classified as having appropriate language development f...

The monitoring of intravenous therapy by nursing staff in medical wards over an 18 hour period was studied. The study focused on the measuring or flow rates, the technique used for unblocking intravenous lines and how recording was managed. Only intravenous therapy which was likely to be in situ for longer than a 24 hour period was studied in randomly selected medical wards. Procedures were car...

The use of ATV’s both recreationally and in the workplace (particularly on farms in Australia), continue to be major contributors to fatal and serious injuries both in the USA and Australia. This paper firstly presents the findings from the authors’ 2003 study into ATV safety and potential countermeasures [1], and secondly, some 10 years later, leads into the current major test program being un...

OBJECTIVE To describe and analyze the trends of occurrence of underweight, overweight, and obesity in schoolchildren. METHODS This was a longitudinal study of trends conducted in a voluntary sample of Brazilian children and adolescents. The sample was grouped by year of collection (period I: 2005 and 2006; period II: 2007 and 2008, and period III: 2009-2011), age category (children: 7 to 10 y...
