The growing use of clusters in diverse applications, many of which have real-time constraints, requires Qualityof-Service (QoS) support from the underlying cluster interconnect. In this paper, we propose an analytical model that captures the characteristics of a QoS capable wormhole router, which is the basic building block of cluster networks. The model captures the behavior of integrated traf...

poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. the aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (pmeca) particles containing 5-aminosalicylic acid (5-asa). pmeca particles were prepared using the inverse emulsification...

In this study PtFeCo ternary alloys nanoparticles of three dimentional (3D) rhombus shapes dispersed on graphene nanosheets (PtFeCo/Gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (ORR) in polymer-electrolyte fuel cells. A combination of analytical techniques including powder X-ray diffraction, X-ray photoelectron spectra, inductively coupled plasma-...

A method for the Monte Carlo simulation, by digital computer, of the evolution of a call iding and coagulating population of suspended particles is described. Call ision mechanisms studied both separately and in combination are: Brownian motion of the particles, and laminar and isotropic turbulent shearing motions of the suspending fluid. Steady state distributions are obtained by adding unit s...

By a modular combination of mesoscopic detectors and gates, we present a thoughtful pump that transports gas particles against the difference of their density at the expense of the diffusion of another species of gas particles. We also discuss briefly the relevance of the model to the study of structure-function relationship of the biomolecular machines.

This paper treats interaction between finitely many particles where the future state of each particle is obtained from the present states of all other particles by a positive linear combination with time variant coefficients. The main result provides conditions for a common globally asymptotically stable equilibrium to exist. These conditions are, in particular, satisfied if the particles show ...

Treatment of vaccinia virions with 1% sodium dodecyl sulfate in the absence of reducing agents resulted in the release of subviral particles termed "subnucleoids," which contained viral DNA in combination with four polypeptides with molecular weights of 90,000, 68,000, 58,000 and 10,000. Biochemical and electron microscopic studies showed that viral DNA in combination with these polypeptides wa...

In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move. For small amplitudes of the harmonics, it is shown that the current (average velocity) of particles exhibits a sinusoidal shape as...
