Scale-out datacenters mandate high per-server throughput to get the maximum benefit from the large TCO investment. Emerging applications (e.g., data serving and web search) that run in these datacenters operate on vast datasets that are not accommodated by on-die caches of existing server chips. Large caches reduce the die area available for cores and lower performance through long access latency when instructions are fetched. Performance on scale-out workloads is maximized through a modestly-sized ...

The prevalence of bovine tuberculosis (BTB) in dairy cattle in the three major milk producing regions of Eritrea was assessed by subjecting 15,354 dairy cattle, 50 % of Eritrea’s dairy cattle population, to the single intradermal comparative tuberculin test (SICTT). Skin test results were interpreted according to guidelines of the World Organization for Animal Health (OIE) with >4 mm as cutoff in skin thickness increase. In addition, we studied the relation between ‘physiological’ variables related to ...

The effect of ejector area variation to account for the unsteadiness of the driving low-grade solar energy source on the cycle performance of a combined variable geometry solar ejector cooling Organic Rankine Cycle under different operating conditions was studied. An Organic Rankine Cycle was combined with the ejector cooling cycle to utilize the excess solar heat in peak hours and to generate power. Simulation and modeling of the system were conducted using the Engineering Equation Solver and Ebsilon ...

Abstract Abstract A Sybil attack consists of an adversary assuming multiple identities to defeat the trust of an existing reputation system. When Sybil attacks are launched in vehicular networks, the mobility of vehicles increases the difficulty of identifying the malicious vehicle location. In this paper, a novel protocol for Sybil detection in vehicular networks is presented. Considering that vehicular networks are cyber-physical systems, the technique exploits well grounded results in the physical ( ...

Introduction Platelet-rich plasma (PRP) intra-articular injections have gained popularity and are suggested to be more effective and longer lasting than corticosteroid or visco-supplementation therapy. There are few studies comparing PRP with corticosteroid injections and none comparing PRP in patients with bilateral knee osteoarthritis with the patient acting as their own control. Methods We performed a double-blind randomized controlled trial including 29 patients (58 knees) with radiologically ...

The reply network is a severe performance bottleneck in General Purpose Graphic Processing Units (GPGPUs), as the communication path from memory controllers (MC) to cores is often congested. In this paper, we find that instead of relying on the congested communication path between MCs and cores, the unused core-to-core communication path can be leveraged to transfer data blocks between cores. We propose the inter-core Locality-Aware Last-Level Cache (LA-LLC), which requires only few bits per cache ...

Abstract Introduction In Sudan, the number of end‐stage kidney disease (ESKD) patients receiving hemodialysis (HD) is growing. Patients and their families incur a high out‐of‐pocket expenditure (OOPE), given that HD treatment is expensive. There are limited data about OOP spending on HD in the country. This study aims to explore patients' OOP expense on direct medical and nonmedical goods and services and to which extent they can be predicted from sociodemographic characteristics, health insurance ...

Heterogeneous processors (e.g., ARM’s big.LITTLE) improve performance in power-constrained environments by executing applications on the ‘little’ low-power core and move them to the ‘big’ high-performance core when there is available power budget. The total time spent on the big core depends on the rate at which the application dissipates the available power budget. When applications with different big-core power consumption characteristics concurrently execute on a heterogeneous processor, it is best ...

Heterogeneous chip multicore processors (HCMPs) equipped with multiple voltage-frequency (V-F) operating points provide a wide spectrum of power-performance tradeoff opportunities. This work targets the performance of HCMPs under a power cap. We show that for any performance optimization technique to work under power constraints, the default set of V-F operating points in HCMPs must be first filtered based on the application's power and performance characteristics. Attempting to find operating points ...

Analytical performance models yield valuable architectural insight without incurring the excessive runtime overheads of simulation. In this work, we study contemporary GPU applications and find that the key performance-related behavior of such applications is distinct from traditional GPU applications. The key issue is that these GPU applications are memory-intensive and have poor spatial locality, which implies that the loads of different threads commonly access different cache blocks. Such memory- ...

Runahead execution improves processor performance by accurately prefetching long-latency memory accesses. When a long-latency load causes the instruction window to fill up and halt the pipeline, the processor enters runahead mode and keeps speculatively executing code to trigger accurate prefetches. A recent improvement tracks the chain of instructions that leads to the long-latency load, stores it in a runahead buffer, and executes only this chain during runahead execution, with the purpose of ...

The accurate forecast of residential water demand is critically important for arid and oil rich countries such as Saudi Arabia which depend on costly desalination plants to satisfy the growing water demand. Achieving the desired prediction accuracy is a challenging task since the forecast model should take into consideration a variety of factors such as economic development, climate conditions and population growth. The task is further complicated given that the water sector in the country is characterized ...

Cushing's disease is caused by an excess of cortisol. In a cushingoid state, excess cortisol leads to a cytoplasmic accumulation of cytokeratin filaments. This accumulation of cytokeratin filaments and hyalinization characterizes a Crooke cell tumor which is an interesting variant of corticotroph adenoma (1) This transformation is known as Crooke’s cell transformation. Crooke’s cell tumors are very rare (largest case series of 36) reported by George et al. (2), aggressive, and prone to recurrence after ...
