A characterization of nested spaces in terms of their order theoretic properties is given. This characterization is analogous to the order theoretic characterization of trees given by L. E. Ward, Jr. Partial orders in topological spaces have been of great interest to topologists since the classic work of Nachbin [7]. Later L. E. Ward, Jr. [11] studied partially ordered topological spaces and in...

An approach for computing the correlations of species richness values obtained from nested and non-nested sampling schemes is described. The correlations obtained are used to construct species accumulation curves for the Carolina Vegetation Survey data set using the log Arrhenius, Gleason, and Arrhenius models. These models are then used to predict the richness at the 400 m2 scale, a value outs...

Anomaly detection algorithms have been proved to be useful in the search of new physics beyond Standard Model. However, a prerequisite for using an anomaly algorithm is that signal sought indeed anomalous. This does not always hold true, example when interference between and Model becomes important. In this case, no longer detection. To overcome difficulty, we propose nested algorithm, which ap...

A binary matrix is fully nested if its columns form a chain of subsets; that is, any two columns are ordered by the subset relation, where we view each column as a subset of the rows indicated by the 1-entries. A binary matrix is k-nested if its columns can be partitioned into k pairwise disjoint blocks, each of which is fully nested. Such nested patterns are encountered, for example, in presen...

The real time implementation algorithms always include nested loops which require important execution times. Thus, several nested loop parallelism techniques have been proposed with the aim of decreasing their execution times. These techniques can be classified in terms of granularity, which are the iteration level parallelism and the instruction level parallelism. In the case of the instructio...

In this paper we address the problem of partitioning nested loops with non-uniform (irregular) dependence vectors. Parallelizing and partitioning of nested loops requires efficient inter-iteration dependence analysis. Although many methods exist for nested loop partitioning, most of these perform poorly when parallelizing nested loops with irregular dependences. Unlike the case of nested loops ...

OBJECTIVE To investigate potential associations between dietary patterns (defined using factor analysis) and difficulty conceiving. DESIGN Case-control study nested in a Spanish cohort of university graduates (Seguimiento Universidad de Navarra [SUN] Project). SETTING Female university graduates all over Spain participating in the SUN Project. PATIENT(S) A total of 485 women, aged 20-45 y...

The recently introduced nested sampling algorithm allows the direct and efficient calculation of the partition function of atomistic systems. We demonstrate its applicability to condensed phase systems with periodic boundary conditions by studying the three-dimensional hard-sphere model. Having obtained the partition function, we show how easy it is to calculate the compressibility and the free...

I. Background Seborrheic keratoses are common, benign, pigmented epidermal tumors.[1] Many terms such as senile wart, melanoacanthoma, basal cell papilloma, senile keratosis and seborrheic wart have been applied, but seborrheic keratosis is the most widely accepted term. These usually develop after the age of 50 years although occasionally, seen in young adulthood without any sexual predilectio...
