Abstract

Function-as-a-Service (FaaS) struggles with burst-parallel jobs due to needing multiple independent invocations to start a job. The lack of a group invocation primitive complicates application development and overlooks crucial aspects like locality and worker communication. We introduce a new serverless solution designed specifically for burst-parallel jobs. Unlike FaaS, our solution ensures job-level isolation using a group invocation primitive, allowing large groups of workers to be launched simultaneously. This method optimizes resource allocation by consolidating workers into fewer containers, speeding up their initialization and enhancing locality. Enhanced locality drastically reduces remote communication compared to FaaS, and combined with simultaneity, it enables workers to communicate synchronously via message passing and group collectives. This makes applications that are impractical with FaaS feasible. We implemented our solution on OpenWhisk, providing a communication middleware that efficiently uses locality with zero-copy messaging. Evaluations show that it reduces job invocation and communication latency, resulting in a 2$\times$ speed-up for TeraSort and a 98.5% reduction in remote communication for PageRank (13$\times$ speed-up) compared to traditional FaaS., Comment: 14 pages, 11 figures, article preprint

Abstract

Carbon nanotubes dispersion within the polymer matrix is a very important factor to take into account when developing new nanocomposites with optimized properties. In this article, dispersion studies have been carried out with polypropylene filled with 1% of multiwall carbon nanotubes. The nanocomposites were obtained by melt compounding in a corotative twin screw extruder. Processing parameters as screw speed, screw configuration and feeding technology were modified to analyse their effect onto carbon nanotubes dispersion. Developed nanocomposites were exposed to microwave heating (5.8 GHz, 700 W, 60 min) and heating temperature was monitored. The relation between dispersion level of carbon nanotubes and heating effectiveness was studied. Microwave heating efficiency of carbon nanotubes was increased as dispersion was improved. Electrical conductivity of nanocomposites was measured and used as indirect variable of microwave heating susceptor of carbon nanotubes nanocomposites. Higher electrical conductivity indicates a better microwave susceptor propertiy of the nanocomposite., INTRODUCTION Microwaves are a part of the continuous electromagnetic spectrum that extends from low-frequency alternating currents to cosmic rays [1]. Microwaves propagate through empty space at the light speed and [...]

Abstract

Prospective, longitudinal, descriptive study was conducted from January 2016 to January 2018 to detect nerve dysfunction after hip arthroscopy. A total of 110 patients were included. Twenty-four hours after surgery, 62.7% reported symptoms of abnormal sensation at least in one area. The most common was the perineal area. Three weeks after hip arthroscopy, 42.6% still experienced abnormal sensation. Six months after hip arthroscopy, only one patient remained with symptoms. Nerve dysfunction after HA was more common than has been reported in the literature within large populations. Traction time was a significant factor for the development of perineal nerve dysfunction.

Abstract

Según se pudo observar durante la atención brindada a pacientes que requieren prótesis dentales fijas, dentro del ámbito del Curso de Rehabilitación Oral que se dicta desde hace 10 años en el Circulo Odontológico de Córdoba, existe una carencia absoluta, por parte de los pacientes, respecto del conocimiento necesario para el mantenimiento de su prótesis, con el consiguiente deterioro de la misma y la pérdida de salud bucal. Estas alteraciones de salud se manifiestan en el orden bucal, caracterizadas principalmente por infecciones, inflamaciones y lesiones cancerizables, pudiendo también, en algunos casos, acarrear consecuencia en la salud general. Nuestra inquietud, conforme lo manifestado por los mismos pacientes, se centra en la ausencia de elementos informativos que posibiliten el conocimiento y, por ende, la prevención de patologías bucales con el consiguiente mantenimiento de la salud de quienes poseen Prótesis Dentales Fijas. Remarcamos el concepto de la “ausencia absoluta de elementos”, ya que no hay registros, escritos orales, visuales o de cualquier otra índole, destinados a orientar en este sector específico de la salud.El diálogo personalizado ha sido hasta ahora la única vía de conocimiento de esta realidad. El impacto social de esta metodología es muy pobre, ya que se limita exclusivamente al paciente que tiene la inquietud, pero no posibilita un intercambio de saberes entre todos los actores incluidos en la problemática Creemos en la necesidad de construir mecanismos de difusión y promoción de la salud que aborden la problemática específica planteada, mediante la implementación de mecanismos que perduren en el tiempo y posibiliten la mejora continua de las técnicas necesarias a fin de generar en los pacientes un estado de salud perdurable en el tiempo. http://revistas.unc.edu.ar/index.php/HUELLAS/issue/view/369/showToc publishedVersion Otras Ciencias de la Salud

Abstract

In this work, we present thermoplastic nanocomposites of polycarbonate (PC) matrix with hybrid nanofillers system formed by a melt-mixing approach. Various concentrations of multi-walled carbon nanotubes (MWCNT) and graphene nanoplatelets (GnP) were mixed in to PC and the melt was homogenized. The nanocomposites were compression molded and characterized by different techniques. Torque dependence on the nanofiller composition increased with the presence of carbon nanotubes. The synergy of carbon nanotubes and GnP showed exponential increase of thermal conductivity, which was compared to logarithmic increase for nanocomposite with no MWCNT. Decrease of Shore A hardness at elevated loads present for all investigated nanocomposites was correlated with the expected low homogeneity caused by a low shear during melt-mixing. Mathematical model was used to calculate elastic modulus from Shore A tests results. Vicat softening temperature (VST) showed opposite pattern for hybrid nanocomposites and for PC-MWCNT increasing in the latter case. Electrical conductivity boost was explained by the collective effect of high nanofiller loads and synergy of MWCNT and GnP. [ABSTRACT FROM AUTHOR]

Abstract

Nanocomposites of polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) with multiwall carbon nanotubes (MWCNT) prepared by masterbatch dilution are investigated in this work. Melt compounding with twin screw extruder is followed by complete characterization of morphology, rheological-, mechanical-, and thermal-properties of the nanocomposites. Light-transmission- and scanning electron microscopy shows the preferential location of MWCNT in the PC. Nevertheless, relatively good dispersion in the whole matrix is achieved, what is corroborated with the specific mechanical energy. The study of viscoelastic properties of PC/ABS-MWCNT shows the fluid-solid transition below 0.5 wt % MWCNT. Beyond this point the continuous nanofiller network is formed in the matrix promoting the reinforcement. Addition of 0.5 wt % MWCNT reduces ductility of PC/ABS and enhances Young's modulus by about 30% and yield stress by about 20%. Moreover, theoretical values of stiffness calculated within this work agree with the experimental data. Electrical conductivity, showing percolation at 2.0 wt % MWCNT, are influenced by processing temperature. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40271. [ABSTRACT FROM AUTHOR]
