The increasing complexity of modern and future multi-core/multithreaded processors rises the question of how to best utilize processor resources. On one side, Amdahl’s Law limits the maximum theoretical speedup of parallel applications while, on the other side, the increasing complexity of runtime programming language may introduce implicit serialization points. Several studies demonstrated tha...

syntax trees are represented as Prolog terms but at the same time with an acceptable concrete appearance. A defining interpreter consists of the following predicates. program(program, final-storage) statement(statement, storage-before, storage-after) expression(expression, storage, integer) condition(condition, storage, ftrue, falseg) Some of the rules of this interpreter are shown in the follo...

In this paper, several binary mask based Depth From Defocus (DFD) algorithms are proposed to improve autofocusing performance and robustness. A binary mask is defined by thresholding image Laplacian to remove unreliable points with low Signal-to-Noise Ratio (SNR). Three different DFD schemes-with/without spatial integration and with/without squaring-are investigated and evaluated, both through ...

in diagnostic and research bacteriology settings with budget and staff restrictions, fast and cost-effective genome extraction methods are desirable. if not inactivated properly, cellular and/or environmental dna nucleases will degrade genomic material during the extraction stage, and therefore might give rise to incorrect results in pcr experiments. when crude cell extracts, proteinase k–treat...

A significant component of the aging process is genetically determined. Numerous theories of aging exist, many of which postulate the existence of "longevity genes." Recent advances in molecular biological and other techniques have allowed a significantly greater understanding of aging and age-related disease. This will be illustrated by four genetic and sporadic diseases: Alzheimer's disease (...

Microvascular changes in the mammary gland in mice during pregnancy and lactation were investigated by scanning electron microscopy (SEM) with a corrosion cast method, tvansmission e]eetron microscopy (TEM) and morphometry. By SEM, duct-associated capillary plexuses were sparsety distributed to branch into adipocytes during virgin period. With advance in pregnancy, both branches from the capMar...
