Most scientiic and Digital Signal Processing (DSP) applications are recursive or iterative. Transformation techniques are usually applied to get optimal execution rates in parallel and/or pipeline systems. The retiming technique is a common and valuable transformation tool in one-dimensional problems, when loops are represented by data ow graphs (DFGs). In this paper, uniform nested loops are m...

The transmembrane subunit of the Glc transporter (IICB(Glc)), which mediates uptake and concomitant phosphorylation of glucose, spans the membrane eight times. Variants of IICB(Glc) with the native N and C termini joined and new N and C termini in the periplasmic and cytoplasmic surface loops were expressed in Escherichia coli. In vivo transport/in vitro phosphotransferase activities of the cir...

The most versatile application for digital phase locked loops is for clock generation and clock recovery in any complex computer architecture like a microprocessor or microcontroller, network processors. Digital Phase locked loops are commonly used to generate timing on chip clocks in high performance mixed signal analog and digital systems. Most of the systems employ digital PLL mainly for syn...

We constructed cDNA clones encoding fragments of band 3 in which the membrane domain was truncated from either the N or the C terminus within each of the first four exofacial loops. The truncations containing the C terminus of the protein were fused with the cleavable N-terminal signal sequence of glycophorin A to facilitate the correct orientation of the most N-terminal band 3 membrane span. C...

Gravitational wave signatures from cosmic strings are analyzed numerically. Cosmic string networks form during phase transistions in the early universe and these networks of long cosmic strings break into loops that radiate energy in the form of gravitational waves until they decay. The gravitational waves come in the form of harmonic modes from individual string loops, a “confusion noise” from...

The main result of this paper is the determination of all nonassociative Moufang loops of orders *31. Combinatorial type methods are used to consider a number of cases which lead to the discovery of 13 loops of the type in question and prove that there can be no others. All of the loops found are isomorphic to all of their loop isotopes, are solvable, and satisfy both Lagrange's theorem and Syl...

Context. The common flare scenario comprises an acceleration site in the corona and particle transport to the chromosphere. Using satellites available to date it has become possible to distinguish between the two processes of acceleration and transport, and study the particle propagation in flare loops in detail, as well as complete comparisons with theoretical predictions. Aims. We complete a ...

Previous analyses (e.g., [1, 2]) of digital phase-locked loops (DPLLs) are based on the traditions of analog loops and introduce analog considerations, such as loop-filter time constants and uncompensated gain variations, that are unnecessary for “fully digital” loops. This reliance on analog tradition makes digital-loop analysis unnecessarily cumbersome and impedes the progress of analysts wit...

The present work is devoted to the analysis of the G-quadruplex DNA structure using the bioinformatics method. The interest towards quadruplex DNAs is determined by their involvement in the functioning of telomeres and onco-promoters as well as by the possibility to create on their basis aptamers and nanostructures. Here, we present an algorithm for a general analysis of the polymorphism of the...
