We are now in big data era, advances in data collection and management technologies have led to large databases. For example, domains such as Medicine, Biology, Music and experimental sciences in general, are all characterized by large data sequences. Considering the amount of space the big data required and the amount of IO required to fetch the big data, data compression has become an efficie...

The most prominent feature of the architecture of the cortex is its horizontal organization into layers. Each layer contains different cell types, and forms different types of connections with other neurons. However, a strong vertical organization is often also apparent: neurons stacked on top of each other through the depth of the cortex tend to be connected and have similar response propertie...

Although sequences within the C terminus of apolipoprotein B (apoB) have been implicated in the formation of covalent lipoprotein(a) [Lp(a)] particles, sequences in apoB that mediate initial noncovalent interaction with apo(a) remain to be characterized. To address this question, we have used an affinity chromatography method in which 2 recombinant forms of apo(a) [r-apo(a); either a 17-kringle...

In order to evaluate the in situ degradative capabilities of microorganisms in an underground reactor facility housing two flowthrough columns filled with aquifer soil, we examined the distribution and phylogeny of gene transcripts encoding enzymes capable of catalyzing the cleavage of the chlorinated aromatic ring during transformation of the main pollutant, chlorobenzene. Initial biostimulati...

Microarray analysis methods can be applied to characteristic data obtained from biological sequences in matrix form (which could include data from experiments or bioassays as well). The rows correspond to a genome region (intron or exon) or a protein, the columns to data obtained from the genome or proteins under selected conditions. In such a dry microarray, tasks like protein classification a...

Corals are known to harbor diverse microbial communities of Bacteria and Archaea, yet the ecological role of these microorganisms remains largely unknown. Here we report putative ammonia monooxygenase subunit A (amoA) genes of archaeal origin associated with corals. Multiple DNA samples drawn from nine coral species and four different reef locations were PCR screened for archaeal and bacterial ...

ACT does not suggest any regulations for columns under torsion. However, by all means, the number of such columns used in steel and concrete structures is abundant. In this paper, using the results of laboratory tests on 35 square and rectangular columns with intermediate slender ratios, relations for determination of torsional strengths of reinforced concrete under axial compression have been ...

van der Zee and Crielaard recently reported the contamination of Qiagen DNA extraction columns with Legionella species (6). We have independently made this discovery and have attempted to further characterize the contaminating DNA. We used the Qiagen columns (QIAamp DNA minikit; Qiagen, Hilden, Germany) for the extraction of DNA from a variety of clinical samples to be tested for Legionella DNA...
