While graphics processing units (GPUs) have gained wide adoption as accelerators for general-purpose applications (GPGPU), the end-to-end reliability implications of their use have not been quantified. Fault injection is a widely used method for evaluating the reliability of applications. However, building a fault injector for GPGPU applications is challenging due to their massive parallelism, ...

Enterprise-system upgrades are unreliable and often produce downtime or data-loss. Errors in the upgrade procedure, such as broken dependencies, constitute the leading cause of upgrade failures. We propose a novel upgradecentric fault model, based on data from three independent sources, which focuses on the impact of procedural errors rather than software defects. We show that current approache...

Phone touchscreens, and other similar hardware components such as orientation sensors, wireless charging controllers, and NFC readers, are often produced by thirdparty manufacturers and not by the phone vendors themselves. Third-party driver source code to support these components is integrated into the vendor’s source code. In contrast to “pluggable” drivers, such as USB or network drivers, th...

BACKGROUND Lateral epicondylitis (LE) is a common musculoskeletal disorder for which an effective treatment strategy remains unknown. PURPOSE To examine whether a single injection of platelet-rich plasma (PRP) is more effective than placebo (saline) or glucocorticoid in reducing pain in adults with LE after 3 months. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS ...

Background: Nowadays, the most important aspect of hemodialysis is the technical method of anticoagulation of extracorporeal circuit. This quasi-experimental study was performed to compare three methods of heparinization in the extracorporeal circulation. Methods: Twenty-seven hemodialysis patients referring to Rafsanjan Hemodialysis Center with the weight range of 50-90 kg and normal Clotting ...

This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...

AIM To evaluate the effectiveness of a new root canal irrigation technique with intracanal aspiration in removing the smear layer and to assess irrigant extrusion ex vivo. METHODOLOGY Thirty-five instrumented canals of extracted human canine teeth that had been resected apically by removing 3 mm of the root tip were divided into one control and four experimental groups of seven teeth each. Th...

Effects of a short-term hyper- and hypoprolactinaemia on serum concentrations of LH, testosterone and semen quality in six male Beagles were investigated. Blood samples were collected at 3-day intervals for 12 weeks. The time span was divided into five 3-week periods: pre-treatment, metoclopramide (MCP) treatment (0.2 mg/kg orally three times daily), cabergoline (CAB) treatment (5 microg/kg ora...
