This paper describes the method to construct a maze for which the solution path goes along with the line of a closed one stroke drawn curve. If the crossing of the curve is considered a vertex and the curve between the two crossings (vertices) an edge, the closed curve becomes an Eulerian graph. Since maze does not allow the solution path to intersect itself, the proposed method constructs the ...

We present a fast addition algorithm in the Jacobian of a genus 3 non-hyperelliptic curve over a field of any characteristic. When the curve has a rational flex and char(k) > 5, the computational cost for addition is 148M + 15SQ + 2I and 165M + 20SQ + 2I for doubling. An appendix focuses on the computation of flexes in all characteristics. For large odd q, we also show that the set of rational ...

The objective of this traffic safety investigation was to find critical road sections using Postand Preaccident analysis approaches. The Post-accident approach analyzes the effect of road geometric characteristics on accident rate. The study was based on accident and road maintenance data in Western Sweden. A total of 2912 accidents from 2000 to 2005 on 1615 km median-separated roads was collec...

This paper describes a model of fear learning, in which subjects have an option of behavioral responses to impending social defeat. The model generates two types of learning: social avoidance and classical conditioning, dependent upon (1) escape from or (2) social subordination to an aggressor. We hypothesized that social stress provides the impetus as well as the necessary information to stimu...

Blood ethanol and acetaldehyde concentrations were compared in normal young male and female subjects after intravenous infusion of 0.5 g of ethanol/kg body weight. After the infusion was completed, females had significantly higher mean concentrations of blood ethanol than males, but a significantly lower apparent volume of distribution (Vd) of ethanol (0.56 +/- 0.06 1/kg vs 0.68 +/- 0.17 1/kg, ...

BACKGROUND Recent studies have shown the enhanced diagnostic capability of the waist-to-height ratio (WHtR) over BMI. However, while a structured cutoff hierarchy has been established for BMI, a rigorous analysis to define individuals as obese using the WHtR has not been performed on a sample of American adults. This study attempts to establish a cutoff for the WHtR using metabolic syndrome as ...

When previously sedentary men and women follow exercise training programs with ad libitum feeding, men lose body fat, but women do not. The purpose of this study was to evaluate whether this observation could be related to sex differences in the way energy-regulating hormones and appetite perception respond to exercise. Eighteen (9 men, 9 women) overweight/obese individuals completed four bouts...

The receiver operating characteristic curve is a popular tool to characterize the capabilities of diagnostic tests with continuous or ordinal responses. One common design for assessing the accuracy of diagnostic tests involves multiple readers and multiple tests, in which all readers read all test results from the same patients. This design is most commonly used in a radiology setting, where th...

PURPOSE THE AIMS ARE TO: (i) display the multidimensional learning curve of totally laparoscopic distal gastrectomy, and (ii) verify the feasibility of totally laparoscopic distal gastrectomy after learning curve completion by comparing it with laparoscopy-assisted distal gastrectomy. MATERIALS AND METHODS From January 2005 to June 2012, 247 patients who underwent laparoscopy-assisted distal ...
