Bacterial genomic DNA is highly organized into one or few compacted bodies known as nucleoid, which is composed of DNA, RNA and several DNA-binding proteins. These DNA-binding proteins require essential alterations in their expression during stationary phase of growth in order to respond to stressful environmental conditions. Dps (DNA-binding protein from starved cells) is one of such DNA-bindi...

The Dynamite Proving System (DPS) provides an assisted theorem prover for Alloy. In this paper we report our experiences on using DPS in the verification of an industrial size model for compositional bindings in network domains, developed by Pamela Zave at AT&T. We also review the DPS foundations, architecture, and some of its main features.

Abstract Although there have been some studies on the preparation and characteristics of nano‐Fe 3 O 4 ‐filled polyurethane (PU) composites, research focusing quantitative influence degree microphase separation (DPS) crosslinking density (CLD) dynamic viscoelastic properties is rare. In this paper, PU composites are synthesized by incorporating as fillers. The mechanical under alternating loads...

Background and Objectives: To provide efficient recommendation for the prevention of childhood obesity and eating disorders, it is necessary to understand and explore their dietary patterns (DPs). The main aim of the current study was to explore dietary patterns among primary school aged children and determine the relationship between different dietary patterns and  factors including anthr...

Email: [email protected] Objective: University students face academic responsibilities that may produce stress, which may lead to changes in dietary patterns (DPs). These changed patterns can become dysfun...

According to the direct parameter specification (DPS) account, reaction time effects of invisible primes depend on top-down control settings directed to targets (Neumann & Klotz, 1994). If this hypothesis holds, effects of invisible primes should decrease in dual-task as compared with single-task conditions: Prior to the primes control settings for the alternative task should be activated, whic...

Multifunctional protein Dps plays an important role in iron assimilation and a crucial role in bacterial genome packaging. Its monomers form dodecameric spherical particles accumulating ~400 molecules of oxidized iron ions within the protein cavity and applying a flexible N-terminal ends of each subunit for interaction with DNA. Deposition of iron is a well-studied process by which cells remove...

OBJECTIVES The purpose of this study was to prospectively evaluate preexisting partial isthmus block in the context of an electrophysiologically directed linear ablation strategy for typical atrial flutter (AF). BACKGROUND Double potentials (DPs) separated by an isoelectric interval have been recognized as markers of local block. However, the presence and significance of DPs in the cavotricus...

Dynamic Potential Search (DPS) is a recently introduced search algorithm that returns a bounded-suboptimal cost solution. DPS orders nodes in the open-list based on their potentialwhich is a combination of both the gand h-values of a node. In this paper we study the behavior of DPS on weighted graphs. In particular, we develop a new variant of DPS, called DPSUwhich calculates the potential by c...

Exposure of Escherichia coli MG1655 to environmental bacteriophages results in rapid selection for phage-tolerant subpopulations displaying increased biofilm formation. Analysis of one phage-tolerant strain revealed large amounts of the DNA-binding Dps protein in the outer membrane protein and production of fimbria-like structures. In dps and fimA mutant derivatives of MG1655, no selection of p...
