Streszczenie:

Binary switches, which are the primitive units of all digital computing and information processing hardware, are usually benchmarked on the basis of their ‘energy–delay product’, which is the product of the energy dissipated in completing the switching action and the time it takes to complete that action. The lower the energy–delay product, the better the switch (supposedly). This approach ignores the fact that lower energy dissipation and faster switching usually come at the cost of poorer reliability (i.e., a higher switching error rate) and hence the energy–delay product alone cannot be a g

Abstract The heavy chain isotype switch is mediated by a DNA rearrangement between a donor switch region (usually mu) and a recipient switch region (gamma, epsilon, or alpha). Switch regions lie upstream of the appropriate heavy chain constant region gene and are composed of simple sequences repeated in tandem. It is not known to what extent the tandemly repeated sequences are important to the heavy chain switch recombination, and to what extent other features of switch region sequences might contribute to the switch process.

Abstract In the simulation of complex power electronic equipment containing multiple power electronic switches, it is often encountered that the same switch occurs several times in one step, or there are multiple switch actions in one step, that is, multiple switches. When the switching event occurs between two moments, because the voltage value can only be updated at the end of the simulation step, there is a cumulative error in the current obtained by the integration.

ABSTRACT The reciprocal expression of GATA-1 and GATA-2 during hematopoiesis is an important determinant of red blood cell development. Whereas Gata2 is preferentially transcribed early in hematopoiesis, elevated GATA-1 levels result in GATA-1 occupancy at sites upstream of the Gata2 locus and transcriptional repression. GATA-2 occupies these sites in the transcriptionally active locus, suggesting that a “GATA switch” abrogates GATA-2-mediated positive autoregulation.

AbstractThe paper is devoted to obtain original equivalent subsystem method to design of decentralized controller for linear large scale systems. On the theoretical example a new robust decentralized PID switched controller design procedure is obtained for linear time-varying (gain scheduled plant model) uncertain complex system with decentralized output and input structure. Controller design procedure to decentralized controller design performs on the subsystem level. The designed decentralized switched controller ensures the robust stability of closed-loop complex polytopic system with perfo

On the mudflats of the Exe Estuary in southwest England, oystercatchers Haematopus ostralegus switched from eating worms Nereis diversicolor to clams Scrobicularia plana during autumn. A decline in the profitability of worms (from 17 to 4 mg/s handling time) and the food intake of oystercatchers eating worms (from 1300 to < 200 mg/15 min) occurred prior to and during the switch to clams. Declines in profitability and food intake rate were due to seasonal changes in the size and food value of worms available to oystercatchers. Capture rate on worms varied little prior to, or during, the swit

The performance of switches and crossings compared with plain line is complicated by the presence of movable parts, changing rail geometry and non-uniformities in the composite and/or trackbed stiffness. These features lead to complex vehicle–track interactions and higher maintenance costs. The trackbed stiffness is the least well-controlled engineering property. A greater variability in trackbed stiffness leads to higher differential trackbed settlement and associated poorer track quality. At switches and crossings, changes in trackbed stiffness are exacerbated by changing rail properties whi

Many complex genomic rearrangements arise through template switch errors, which occur in DNA replication when there is a transient polymerase switch to an alternate template nearby in three-dimensional space. While typically investigated at kilobase-to-megabase scales, the genomic and evolutionary consequences of this mutational process are not well characterised at smaller scales, where they are often interpreted as clusters of independent substitutions, insertions and deletions. Here we present an improved statistical approach using pair hidden Markov models, and use it to detect and describ

Abstract Background Germany has a long tradition of switch and has long been considered one of the most liberal countries in terms of the release of modern active substances from prescription, the so-called switch. In the period 2000–2016, a total of more than 30 active ingredients – partly in different dosage strengths, dosage forms or indications – were released from prescription status in Germany. Of these, almost half can be described as “innovative” switches. Recently a significant decline of filed switch proposals can be noted, with only a few being successful. Methods Reflecting that th

With the general acceptance that the arterial switch operation represents the surgical treatment of choice for complex complete transposition, an increasing number of centers are leaning towards favoring this approach for simple transposition as well. As the arterial switch procedure is a more difficult surgical procedure than the Mustard or Senning operation, the learning curve has been longer and more hazardous. Centers with large referral bases have, understandably, enjoyed a more concentrated exposure to the arterial switch operation, and are now achieving early rates of mortality as low a

Switching graphs are graphs that contain switches. A switch is a pair of edges that start in the same vertex and of which precisely one edge is enabled at any time. By using a Boolean function called a switch setting, the switches in a switching graph can be put in a fixed direction to obtain an ordinary graph. For many problems, switching graphs are a remarkable straightforward and natural model, but they have hardly been studied. We study the complexity of several natural questions in switching graphs of which some are polynomial, and others are NP-complete. We started investigating switchin

Adverse events may cause treatment discontinuation. Finally, ptÕs preference may be an important issue considering the different route and timing of administration of the two agents.
