We calculate an analytical expression for the terrace-width distribution P(s) for an interacting step system with nearest- and next-nearest-neighbor interactions. Our model is derived by mapping the step system onto a statistically equivalent one-dimensional system of classical particles. The validity of the model is tested with several numerical simulations and experimental results. We explore...

objective(s) primary or adult type hypolactasia, the most common enzyme deficiency in the world, is due to reduced lactase activity in the intestinal cell after weaning. lactase non-persistence is inherited as an autosomal recessive trait. a dna variant, single nucleotide polymorphism c/t−13910 which is located on 13910 base pairs (bp) upstream of the lactase gene (lct) at chromosome 2 has been...

ingle-case research designs are a diverse and powerful set of procedures useful for demonstrating causal relations among clinical phenomena. Although such designs are flexible, efficient, and have been used to make key advances since the earliest days of psychological science, they are currently extremely underused by psychological scientists and clinicians. We review the historical and theoret...

ing the Observer To solve this problem with numerical constraints, Lurette computes an abstract version of the original observer. In this abstract observer, all numerical constraints have been replaced by new Boolean Variables. These new variables are treated as further inputs of the observer. Consider the following observer with a number of numerical constraints: node RELEVANT(X,Y,Z : int; A,B...

Single-case experimental designs are characterized by repeated measurements of an individual's behav­ ior, comparisons across experimental conditions imposed on that individual, and assessment of the measurements' reliability within and across the con­ ditions. Such designs were integral to the develop­ ment of behavioral science. Early work in the field of psychology depended on the analysis o...

This paper provide a structured analysis of US Supreme Court Oral Hearings to enable identification of the relevant issues, factors and facts that can be used to construct a test to resolve a case. Our analysis involves the production of what we term ‘argument component trees’ (ACTs) in which the issues, facts and factors, and the relationship between these, are made explicit. We show how such ...
