Explicit asymptotic series describing solutions to the Laplace equation in the vicinity of a circular edge in a three-dimensional domain was recently provided in Yosibash et al, Int. Jour. Fracture, 168 (2011), pp. 3152. Utilizing it, we extend the quasidual function method (QDFM) for extracting the generalized edge flux intensity functions (GEFIFs) along circular singular edges in the cases of...

The generation of femtosecond x-ray pulses with circular polarization is planned at BESSY II. The paper describes the underlying principle (”femtoslicing”), its technical implementation, and the expected output, based on simulations and measurements.

HSAF is an antifungal natural product with a new mode of action. A rare bacterial iterative PKS-NRPS assembles the HSAF skeleton. The biochemical characterization of the NRPS revealed that the thioesterase (TE) domain possesses the activities of both a protease and a peptide ligase. Active site mutagenesis, circular dichroism spectra, and homology modeling of the TE structure suggested that the...

The data presented here are related to the research article entitled "Expression, purification, and preliminary characterization of human presenilin-2" [1]. Human Presenilin-2 is the catalytic subunit of γ-secretase and a possible calcium leakage channel (Kimberly et al., 2000; Tu et al., 2006) [2], [3]. HisPS2 which was obtained by overexpression in E. coli strain C43 (DE3) was extracted by de...

Besides the catalytic ability, many enzymes contain conserved domains to perform some other physiological functions. However, sometimes these conserved domains were unnecessary or even detrimental to the catalytic process for industrial application of the enzymes. In this study, based on homology modeling and molecular dynamics simulations, we found that Bacillus subtilis aminopeptidase contain...

Preface Old growth is widely acknowledged today as an essential part of managed forests, particularly on public lands. However, this concept is relatively new, evolving since the 1970's when a grassroots movement in the Pacific Northwest began in earnest to define old growth. In response to changes in public attitude, the U.S. Department of Agriculture, Forest Service, began reevaluating its po...

In conventional Kerr and Faraday microscopy, the sample is illuminated with plane-polarized light, a magnetic domain contrast generated by an analyzer making use of or rotation. Here, we demonstrate possibilities analyzer-free magneto-optical microscopy based on magnetization-dependent intensity modulations light. (i) The transverse effect can be applied for in-plane magnetized material, as dem...

Component-Based Development (CBD) is revolutionizing the process of building applications by assembling pre-built reusable components. Components should be designed more for inter-organizational reuse, rather than intra-organization reuse through domain analysis which captures the commonality of the target domain. Moreover, the minor variations within the commonality should also be modeled and ...

This paper, introduces a new lter bank structure called the perfect reconstruction circular convolution (PRCC) lter bank. These lter banks satisfy the perfect reconstruction properties, namely, the paraunitary properties in the discrete frequency domain. We further show how the PRCC analysis and synthesis lter banks are completely implemented in this domain and give a simple and a exible method...

DsrA RNA regulates the translation of two global regulatory proteins in Escherichia coli. DsrA activates the translation of RpoS while repressing the translation of H-NS. The RNA-binding protein Hfq is necessary for DsrA to function in vivo. Although Hfq binds to DsrA in vitro, the role of Hfq in DsrA-mediated regulation is not known. One hypothesis was that Hfq acts as an RNA chaperone by unfo...
