This paper reports a 45nm spin-transfer-torque (STT) MRAM embedded into a standard CMOS logic platform that employs low-power (LP) transistors and Cu/low-k BEOL. We believe that this is the first-ever demonstration of embedded STT MRAM that is fully compatible with the 45nm logic technology. To ensure the switching margin, a novel “reverseconnection” 1T/1MT(More)
We retrospectively analyzed the clinical results of treatment of impacted or undisplaced femoral neck fractures (Garden types 1 and 2) by osteosynthesis in elderly patients >70-year old. We retrospectively reviewed the radiological results of 52 patients who were followed up for at least 6 months from April 2002 to December 2008. The average age of the(More)
Laser-assisted uvulopalatoplasty (LAUP) reduces the need for general anesthesia, bleeding and the operation time compared with uvulopalatopharyngoplasty (UPPP), but the postoperative pain is more severe due to the thermal damage to tissues, and the procedure often causes serious scar contracture of the soft palate, with foreign body sensation also occurring(More)
Complications of laparoscopic adjustable gastric banding (LAGB) are well documented including migration, erosion, prolapse, infection, pouch dilatation, and gastric perforation. Band prolapse within the first 5 years after LAGB is observed in about 5% of cases, requiring an operative procedure. Here we report our experience of endoscopic treatment of band(More)
The existing SAR (security aware routing) protocol is an ad hoc network protocol that finds a secure path using the security level of mobile nodes. However, the SAR protocol sometimes transfers data through inefficient transmission paths because It always tries to find secure nodes for a safe transmission. Since it is a protocol based on AODV, the new(More)
Glucose 6 phosphate dehydrogenase (G6PD) is an enzyme related to the metabolism of glutation, an antioxidant agent. Its deficiency causes hemolisis, generally well tolerated. However there are some factors including, exercise, infections and oxidants drugs that stimulate the hemolisis of the older red blood cells. We report two patients with G6PD(More)
In this paper, we propose a novel and efficient genetic algorithm to the optimal sensor placement of nodes for a wireless sensor network designed to monitor enemy vehicles in a hostile region. A notable feature of our genetic algorithm is the combination of mutation derived from physics and crossover in which heterogeneity between genes is removed by(More)
To evaluate whether the flow-mediated vasodilation and coronary flow reserve are impaired or not in patients with vasospastic angina (VA), we measured the changes of epicardial coronary artery diameter and flow reserve in spasm related-left anterior descending coronary artery (LAD). The flow mediated-response of epicardial coronary arteries in 15 VA were(More)
An advanced high-level approach for programming of real-time distributed computing applications, the TMO (Time-triggered Message-triggered Object) programming and specification scheme, has been enabled without creating any new language or compiler. Instead, a middleware system named the TMO Support Middleware (TMOSM) and an API that wraps around the(More)
Understanding the thermal budget of perpendicular materials is crucial for the potential application perpendicular magnetic tunnel junctions. In this paper, we study the effects of high-temperature rapid thermal annealing on the structural and magnetic properties of ultra-thin Co/Pd multilayers deposited at room temperature. It is shown that perpendicular(More)
