Speculative multithreading (SpMT) increases the performance by means of exploiting specula-tive thread-level parallelism. In this paper we describe the Mitosis framework, which is a com-bined hardware-software approach to finding and exploiting speculative thread-level parallelism,even in the presence of frequent dependences between threads. The approach is based on predict-ing/...
Most applications driving the advancements in microarchitecture and memory system research have a non-negligible interaction with the operating system. Yet, most architectural investigations are based on user-level simulators in which operating system activity is not modelled. This has motivated us to design SimWattch, a microarchitectural modeling infrastructure. SimWattch is based on Simics –...
Java is widely deployed on a variety of processor architectures. Consequently, an understanding of microarchitecture level Java performance is critical to optimize current systems and to aid design and development of future processor architectures for Java. Although this is facilitated by a rich set of processor performance counters featured on several contemporary processors, complex processor...
PURPOSE Increasing evidence supported that semaphorin 3A (Sema3A), insulin-like growth factor (IGF)-1 and β-catenin were involved in the development of osteoporosis and diabetes. This study is aimed to evaluate whether Sema3A/IGF-1/β-catenin is directly involved in the alterations of bone microarchitecture and bone strength of diabetic rats. METHODS Diabetic rats were induced by streptozotoci...
Osteoporosis (OP); It is a metabolic bone disease characterized by decreased mineral density (BMD) and strength, increased fragility fracture risk, deterioration in the microarchitecture of tissue. The most important cause morbidity mortality OP are fractures such as osteoporotic hip fractures. Prevention treatment osteoporosis can prevent comorbidities. In this paper, available information abo...
The trabecular bone score (TBS) is a new method to describe skeletal microarchitecture from the dual energy X-ray absorptiometry (DXA) image of the lumbar spine. While TBS is not a direct physical measurement of trabecular microarchitecture, it correlates with micro-computed tomography (µCT) measures of bone volume fraction, connectivity density, trabecular number, and trabecular separation, an...
PURPOSE To assess the effect of external mechanical microstimuli of controlled magnitude on the microarchitecture of the peri-implant bone beds in rat tibiae. MATERIALS AND METHODS Tibiae of forty rats were fitted with two transcutaneous titanium cylinders. After healing, the implants were loaded to 1 to 3 N, five days/week for four weeks. These force levels translated into intraosseous strai...
Intels processors based on the original 45nm Intel Coret microarchitecture, originally referred to by the codename Penryn, improved the energy efficiency and performance per watt of the Intel Core microarchitecture. This paper discusses the new technologies introduced in the Penryn family of processors that enabled lower idle power and higher performance levels. The Penryn family of processors ...
