A uniform multiprocessor machine is comprised of an integer number of processors. Each processor P is characterized by a computing capacity P:c with the interpretation that a job executing on processor P for t time units completes (Pj:c t) units of execution. The scheduling of systems of periodic tasks on uniform multiprocessor systems is considered.

Recently, Emma Lehmer constructed a parametric family of units in real quintic fields of prime conductor p = t + 5t + I5t + 25/ + 25 as translates of Gaussian periods. Later, Schoof and Washington showed that these units were fundamental units. In this note, we observe that Lehmer's family comes from the covering of modular curves X",(25) —► ,Y0(25). This gives a conceptual explanation for the ...

A method for red ucing t he number of uni ts in t he hidden layers of a feed-for war d neur al network is pr esented . Starting wit h a net that is oversize, t he redundan t unit s in t he hidden layer are elimina ted by introducing an addit ional cost fun ct ion on a set of auxiliary linear response uni ts . T he extra cost funct ion enables t he auxiliary units to fuse together the redundant ...

Human listeners hear an asymmetry in the perception of damped and ramped sinusoids; the partial loudness of the envelope component is greater than the partial loudness of the carrier component for damped sinusoids. Here we show that an asymmetry also occurs in the physiological responses of most units in the ventral cochlear nucleus to these same sounds. The activity elicited by damped sinusoid...

Inspired by Stillman Drake’s definition of G&lean Units as those for which & = (g)g where g is any finite, constant acceleration measured in units of L and T, we construct a lcinematical dimensional analysis based only on two universal, dimensionless constants. For the linear relation between L and T we use Einsteinian Units 6 = (1)~. For orbiting masses negligible compared to some mass unit M,...

OBJECTIVE Current study aimed toward the early prediction of neonatal intraventricular hemorrhage (IVH) for better management and prognosis. METHODS This prospective study was conducted on forty neonates at the Neonatal Intensive Care Unit of Pediatrics and Medical Biochemistry department (Tanta University, Egypt) from July 2016 to June 2017. Cord blood erythropoietin and venous blood Activin...

This study was designed to test the process of selecting encephalitogenic T cell lines in the Lewis rat using recombinant human IL-2 (rhIL-2) in comparison to TCGF. The lines were tested for growth, antigen induced proliferation, cytokine production, V-beta 8.2 expression and pathogenicity. We now report that rhIL-2 and TCGF were equally effective in supporting short-term pathogenic T-cell line...

Energy-coupling factor (ECF) transporters are a huge group of micronutrient importers in prokaryotes. They are composed of a substrate-specific transmembrane protein (S component) and a module consisting of a moderately conserved transmembrane protein (T component) and two ABC ATPase domains (A components). Modules of A and T units may be dedicated to a specific S component or shared by many di...

as organization developed and the control area of management increased, assessment and control of organizational units became more essential for managers. usually managers try to assess the performance of units by defining and measuring varied indexes in operational department. also this method transforms some idea to managers, but doesn't attention to interrelationship between these index...

Thymus-derived(T) lymphocytes have been shown to display antigen specificity. The antigen-recognition units on T lymphocytes, in contrast to those on B lymphocytes, do not appear to be of the conventional immunoglobul in (Ig) type. Recent studies from various laboratories (1-5) have demonstrated that the antigen-specific T cell factors derived from helper or suppressor T cells possess the ant i...
