High-Performance Computation Using a Single-Flux Quantum Accelerator
Farhad Mehdipour,Hiroaki Honda,Hiroshi Kataoka,Koji Inoue,Kazuaki Murakami 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
A large-scale reconfigurable data-path (LSRDP) processor based on single-flux quantum circuits has been proposed to overcome the barriers originating from the CMOS technology. LSRDP is integrated to a general purpose processor in a high-performance computing system to accelerate the execution of data flow graphs extracted from scientific applications. The LSRDP micro-architecture and its specifications will be presented in this paper. A preliminary performance evaluation of the reconfigurable processor will be given as well.

Silver Sulfadiazine-loaded PVA/CMC Nanofibers for the Treatment of Wounds Caused by Excision
Reza Alipour,Alireza Khorshidi,Abdollah Fallah Shojaei,Farhad Mashayekhi,Mohammad Javad Mehdipour Moghaddam 한국섬유공학회 2019 Fibers and polymers Vol.20 No.12
Polyvinyl alcohol/carboxymethylcellulose/silver sulfadiazine composite nanofibers (PVA/CMC/SSD) containingdifferent proportions of each ingredient were prepared by electrospinning and characterized by Fourier-transform infraredspectroscopy (FTIR), scanning electron microscopy (SEM), thermo-gravimetric analysis (TGA), powder X-ray diffractionanalysis (XRD), atomic absorption spectroscopy (AAS), and ultraviolet-visible (UV-Vis) spectroscopy. The obtainednanofibers were uni-axially formed with randomly oriented longitudinal axes without entanglement, and their meandiameters ranged from 160 to 210 nm. Silver sulfadiazine, on the other hand, was appeared as a non-uniform dispersion ofspherical nanoparticles ranging from 35 to 75 nm over the surface of nanofibers. Efficacy of the silver sulfadiazine loadednanofibers for treatment of wounds caused be excision in rabbits in a period of 14 days was evaluated and it was found thatthe extent of skin repair in the applied dressing depends on the total Ag content. The dressing composed of 73.6:24.6:1.8weight percent of PVA/CMC/SSD provided the best result in comparison with a control dressing made form PVA/CMC(88.8:11.2 %). In vitro cell viability of fibers on HSF-PI 18 fibroblast like cells was assessed by MTT assay. Antibacterialactivity of the prepared nanofibers was also evaluated against gram-negative Escherichia coli and Pseudomonas aeroginosa,and gram-positive Staphylococcus aureus. PVA/CMC/SSD samples, was shown to have significant inhibition effect incomparison with drug references including penicillin G, chloramphenicol and erythromycin as positive controls (P<0.05).
