Fault-Independent Test-Generation for Software-Based Self-Testing

Software-based self-test (SBST) is being widely used in both manufacturing and in-the-field testing of processor-based devices and Systems-on-Chips. Unfortunately, the stuck-at fault model is increasingly inadequate to match the new and different types of defects in the most recent semiconductor technologies, while the explicit and separate targeting of every fault model in SBST is cumbersome due to the high complexity of the test-generation process, the lack of automation tools, and the high CPU-intensity of the fault-simulation process. Moreover, defects in advanced semiconductor technologies are not always covered by the most commonly used fault-models, and the probability of defect-escapes increases even more. To overcome these shortcomings we propose the first fault-independent SBST method. The proposed method is almost fully automated, it offers high coverage of non-modeled faults by means of a novel SBST-oriented probabilistic metric, and it is very fast as it omits the time-consuming test-generation/fault-simulation processes. Extensive experiments on the OpenRISC OR1200 processor show the advantages of the proposed method

La prostitución en debate

Si bien se observa un avance en las demandas del feminismo, y a pesar de las transformaciones sociales y los derechos conquistados a lo largo de la historia por el movimiento de las mujeres, hay otras problemáticas que nos atañen que siguen siendo postergadas tanto por el Estado como por la sociedad en su conjunto. Una de éstas es la situación de prostitución. Al interior del feminismo existe una gran controversia acerca de si la prostitución es un trabajo y debe legalizarse como tal, o si es una situación de violencia patriarcal que debe abolirse. Este debate se encuentra cada vez más desarrollado y se ve expresado en distintas organizaciones feministas y sindicales. Es por esto que en la presente tesis abordamos el tema de la prostitución en algunas de sus dimensiones políticas. Las preguntas que guiaron nuestra investigación son: ¿Cuáles son los argumentos básicos de las diferentes corrientes feministas respecto al fenómeno prostitucional en Argentina actualmente?, ¿Cuál es el rol/respuesta del Estado mediante sus políticas públicas respecto a la prostitución en Argentina y en la provincia de Mendoza? Por consiguiente, surge la necesidad de analizar el fenómeno de la prostitución desde los argumentos políticos ideológicos de las diferentes corrientes feministas y desde el rol del Estado argentino. Es por eso que nuestro objetivo general en esta indagación se dirige a describir y analizar la prostitución en sus diferentes esferas y relaciones. Como objetivos específicos nos propusimos abordar las políticas públicas respecto a la problemática a nivel nacional, y describir y analizar los diferentes argumentos políticos ideológicos del fenómeno prostitucional de las organizaciones y referentas feministas. Esta investigación es de carácter teórica y de alcance exploratorio-descriptivo. Se propone una estrategia cualitativa de análisis documental que implica una amplia revisión bibliográfica y un atento trabajo hermenéutico sobre los textos. Se realiza un análisis crítico del rol del Estado en relación al fenómeno analizado, rastreando las políticas públicas, leyes y tratados internacionales en Argentina que se vinculan a la problemática estudiada. Además, identificamos el diálogo existente entre el Estado y las organizaciones sociales que le disputan sentido y exigen su intervención en la problemática. A su vez, son desarrollados los nudos problemáticos emergentes en los distintos argumentos en torno a la prostitución en clave comparada, ponderando la tensión entre perspectivas abolicionistas y reglamentaristas e interrogando desde aquí las acciones y manifestaciones institucionales al respecto.Fil: Cantoro, Carla.

Test, Reliability and Functional Safety Trends for Automotive System-on-Chip

This paper encompasses three contributions by industry professionals and university researchers. The contributions describe different trends in automotive products, including both manufacturing test and run-time reliability strategies. The subjects considered in this session deal with critical factors, from optimizing the final test before shipment to market to in-field reliability during operative life

Safety and efficacy of percutaneous nephrolithotomy in the Galdakao - Modified Supine Valdivia position: A prospective analysis

Objective: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL) in the Galdakao- Modified Supine Valdivia (GMSV) position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. Material and methods: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones > 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. Results: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41): staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%), and it was influenced by patients' anatomic abnormalities. Conclusions: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients' anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes

Integrative epigenome-wide analysis demonstrates that DNA methylation may mediate genetic risk in inflammatory bowel disease

Epigenetic alterations may provide important insights into gene-environment interaction in inflammatory bowel disease (IBD). Here we observe epigenome-wide DNA methylation differences in 240 newly-diagnosed IBD cases and 190 controls. These include 439 differentially methylated positions (DMPs) and 5 differentially methylated regions (DMRs), which we study in detail using whole genome bisulphite sequencing. We replicate the top DMP (RPS6KA2) and DMRs (VMP1, ITGB2 and TXK) in an independent cohort. Using paired genetic and epigenetic data, we delineate methylation quantitative trait loci; VMP1/microRNA-21 methylation associates with two polymorphisms in linkage disequilibrium with a known IBD susceptibility variant. Separated cell data shows that IBD-associated hypermethylation within the TXK promoter region negatively correlates with gene expression in whole-blood and CD8+ T cells, but not other cell types. Thus, site-specific DNA methylation changes in IBD relate to underlying genotype and associate with cell-specific alteration in gene expression
