Abstract:

Background. A growing number of patients suffering from ischemic cardiomyopathy are not eligible for conventional revascularization. This has prompted new research in the field of angiogenesis. This study hypothesized that since inflammation is probably the mechanism behind TMR induced angiogenesis; a larger inflammatory response induced by thermal injury may lead to increased angiogenesis.<br>Methods. The model used for this study was coronary artery ligation in the Rat. Four groups of animals were used to compare the novel experimental approach with conventional TMR and with ischemia alone.

Magnetic tunnel junctions (MTJs), which consist of a thin insulation layer sandwiched by two ferromagnetic (FM) layers, are among the key devices of spintronics that have promising technological applications for computer hard disk drives, magnetic random access memory (MRAM) and other future spintronic devices. The work presented here is related to the development of relevant techniques for the preparation and characterization of magnetic films, exchanged biased systems and MTJs. The fabrication and characterization of PtMn/CoFe exchange biased systems and MTJs with Al-O barriers were undertak

Abstract:

Artificial neural networks (ANNs) are used in many types of computing applications. Traditionally, ANNs have been implemented in software, executing on CPUs and even GPUs, which capitalize on the parallelizable nature of ANNs. More recently, FPGAs have become a target platform for ANN implementations due to their relatively low cost, low power, and flexibility. Some safety-critical applications could benefit from ANNs, but these applications require a certain level of reliability. SRAM-based FPGAs are sensitive to single-event upsets (SEUs), which can lead to faults and errors in execution. Ho

Abstract:

FPGAs are attractive devices as they enable the designer to make changes to the system during its lifetime. This is important in the early stages of development when all the details of the final system might not be known yet. In a research environment like at CERN there are many FPGAs used for this very reason and also because they enable high speed communication and processing. The biggest problem at CERN is that the systems might have to operate in a radioactive envi- ronment which is very harsh on electronics. ASICs can be designed to withstand high levels of radiation and are used in many

We have studied the effect of the dipolar magnetic coupling (also known as Néel coupling or &quot;orange-peel&quot; coupling) in tunneling magnetoresistive (TMR) elements. With an in situ scanning tunneling microscope we directly accessed the roughness of the films and found a close correspondence between the values for the coupling fields determined by the magneto-optical Kerr effect and the ones computed on the basis of the measured morphology parameters. We confirm an increase of the dipole coupling between magnetic layers with decreasing barrier thickness as predicted by the model.

Abstract:

Transmyocardial revascularization (TMR) has emerged as an additional therapeutic option for patients suffering from diffuse coronary artery disease (CAD), providing immediate angina relief. The current potential of this therapy focuses on the injection of stem cells, in order to create a synergistic angiogenic effect while increasing myocardial repair and regeneration. Although TMR procedures provide increased vascularization within the myocardium, patients suffering from ischemic cardiomyopathy may not benefit from angiogenesis alone. Therefore, the goal of introducing stem cells is to restor

Abstract:

La triple redundancia modular (TMR) es una técnica bien conocida de mitigación de fallos que proporciona una alta protección frente a fallos únicos pero con un gran coste en términos de área y consumo de potencia. Por esta razón, la redundancia parcial se suele aplicar para aligerar estos sobrecostes. En este contexto, la TMR aproximada (ATMR), que consisten en la implementación de la redundancia triple con versiones aproximadas del circuito a proteger, ha surgido en los últimos años como una alternativa a la replicación parcial, con la ventaja de obtener mejores soluciones de compromiso entre

Abstract:

It is expected that nano-scale devices and interconnections will introduce unprecedented level of defects in the substrates, and architectural designs need to accommodate the uncertainty inherent at such scales. This consideration motivates the search for new architectural paradigms based on redundancy based defect-tolerant designs. However, redundancy is not always a solution to the reliability problem, and often too much or too little redundancy may cause degradation in reliability. The key challenge is in determining the granularity at which defect tolerance is designed, and the level of re

Abstract:

Radiation effects encountered in space or aviation environments can affect the configuration bits in Field Programmable Gate Arrays (FPGA) causing errors in FPGA output. One method of increasing FPGA reliability in radiation environments includes adding redundant logic to mask errors and allow time for repair. Despite the redundancy added with triple modular redundancy (TMR) and configuration scrubbing there exist some configuration bits that individually affect multiple TMR domains causing errors in FPGA output. A new tool called DeBit is introduced that identifies hardware resources associat

Abstract:

Commercial off-the-shelf (COTS) microcontrollers can be useful for non-critical processing on spaceborne platforms. Many of these microprocessors are inexpensive and consume little power. However, the software running on these processors is vulnerable to radiation upsets, which can cause unpredictable program execution or corrupt data. Space missions cannot allow these errors to interrupt functionality or destroy gathered data. As a result, several techniques have been developed to reduce the effect of these upsets. Some proposed techniques involve altering the processor hardware, which is imp

Abstract:

Dans le manuscrit, nous étudions l'impact des défauts sur le transport électronique dépendant du spin dans les jonctions tunnel magnétiques (JTM). Ces études ont été effectuées sur des hétérostructures possédant des barrières tunnel composé de SrTiO3, TiO2 et de MgO. Dans le cas des deux premières structures, nous montrons comment l'oxydation à l'interface induit réduction très prononcée de la magnétorésistance tunnel (TMR). Dans le cas du MgO, des études optiques sur les états induits par les défauts dans la barrière isolante ont été effectué. Nous avons montré qu'il est possible de contrôler

Este trabalho consiste no estudo e análise da suscetibilidade a efeitos da radiação em projetos de circuitos gerados por ferramenta de Síntese de Alto Nível para FPGAs (Field Programmable Gate Array), ou seja, circuitos programáveis e sistemas em chip, do inglês System-on-Chip (SOC). Através de um injetor de falhas por emulação usando o ICAP (Internal Configuration Access Port) localizado dentro do FPGA é possível injetar falhas simples ou acumuladas do tipo SEU (Single Event Upset), definidas como perturbações que podem afetar o funcionamento correto do dispositivo através da inversão de um b
