John Y. Templeton III: Pioneer of modern cardiothoracic surgery.

John Young Templeton III was born in 1917 in Portsmouth, Virginia, and graduated from Jefferson Medical College in 1941. He completed his residency training under Dr. John H. Gibbon, Jr., and was the first resident who worked on Gibbon\u27s heart-lung machine. After his training, he remained at Jefferson as an American Cancer Society fellow and Damon Runyon fellow and went on to become the fourth Samuel D. Gross Professor and Chair of the Department of Surgery in 1967. Dr. Templeton was the recipient of numerous grants and published over 80 papers in the field of cardiothoracic surgery. As a teacher and mentor, he was a beloved figure who placed great faith in his residents. He participated in over 60 professional societies, serving as president to many such as the Philadelphia Academy of Surgery and the Pennsylvania Association of Thoracic Surgery. He was also recognized through his many awards, in particular the John Y. Templeton III lectureship established in 1980 at Jefferson of whom Denton Cooley was the first lecturer. Dr. Templeton retired from practice in 1987. He is forever remembered as an important model of a modern surgeon evident in numerous academic achievements, the admiration and affection of his trainees, and the lives of patients that he had touched

English Proficiency Assessments of Primary and Secondary Students Participating in English in Action: Third Cohort (2014) Large-Scale Quantitative Study

The purpose of the study was to assess the student learning outcomes of English in Action’s (EIA’s) school-based teacher development programme, in terms of improved English language competence (ELC), against recognised international frameworks (specifically, the Graded Examinations in Spoken English [GESE)]; Trinity College London 2013), which map onto the Common European Framework of Reference for Languages (CEFR). Measurably improved student learning outcomes are the ultimate test of success of a teacher development programme. English Proficiency Assessments 2014 is a repeat of the study on the pilot EIA programme (Cohort 14) (EIA 2012), but focusing only on student ELC. The teachers and hence the students of Cohort 3 are substantially greater in number than in the pilot phase (347,000 primary students and almost 1.7 million secondary students compared with around 700 teachers, 35,000 primary students and over 83,000 secondary students in 2011). To enable this increase in scale, the programme has been delivered through a more decentralised model, with much less direct contact with English language teaching (ELT) experts, a greater embedding of expertise within teacher development materials (especially video), and a greater dependence upon localised peer support. This report addresses the following research question: To what extent do the students of Cohort 3 show improved post-intervention EL proficiencies, in speaking and listening, compared with the Cohort 1 2010 preintervention baseline

Reducing Memory Controller Transaction Queue Size in Scalable Memory Systems

Scalable memory systems provide scalable bandwidth to the core growth demands in multicores’ and embedded systems’ processors. In these systems, as memory controllers (MCs) are scaled, memory traffic per MC is reduced, therefore transaction queues become shallower. As a consequence, there is an opportunity to explore transaction queue utilization and its impact on energy. In this paper we propose to evaluating the performance and energy-per-bit impact of the number of entries of the transaction queues along the MCs in these systems. Preliminary results show that reducing 50% of the number of entries, bandwidth and energy-per-bit levels are not affected, while if reducing them of 93%, bandwidth is reduced of 91% and energy-per-bit levels are increased of 780%

Insights on Memory Controller Scaling for Multicore Embedded Systems

In recent years, the growth of the number of cores as well as the frequency of cores along different processor generations has proportionally increased bandwidth needs simultaneously in both CPU and GPU systems. In order to address the communication latency between CPU and GPU memories in recent implementation of heterogeneous mobile embedded systems with hard or firm real-time requirements, sharing the same address space adds significant levels of contention. In addition, when heterogeneous cores are simultaneously present in a single system, memory parallelism is significantly restricted by a small amount of memory controllers (MCs). As a strategy to approach these significant levels of memory pressure, it is proposed in this paper evaluations of the impact of scaling MCs up to four to eight units - limited by motherboard size for embedded purposes. Our findings show that performance is enhanced by a factor of 4× when employing only CPU cores, 4.6× when only GPU cores and finally, 2× when both CPU and GPU cores are simultaneously considered

Development of an Optimization-Based Atomistic-to-Continuum Coupling Method

Atomistic-to-Continuum (AtC) coupling methods are a novel means of computing the properties of a discrete crystal structure, such as those containing defects, that combine the accuracy of an atomistic (fully discrete) model with the efficiency of a continuum model. In this note we extend the optimization-based AtC, formulated in arXiv:1304.4976 for linear, one-dimensional problems to multi-dimensional settings and arbitrary interatomic potentials. We conjecture optimal error estimates for the multidimensional AtC, outline an implementation procedure, and provide numerical results to corroborate the conjecture for a 1D Lennard-Jones system with next-nearest neighbor interactions.Comment: 12 pages, 3 figure

Advances in Modern Clinical Ultrasound

Advances in modern clinical ultrasound include developments in ultrasound signal processing, imaging techniques and clinical applications. Improvements in ultrasound processing include contrast and high-fidelity ultrasound imaging to expand B-mode imaging and microvascular (or microluminal) discrimination. Similarly, volumetric sonography, automated or intelligent ultrasound, and fusion imaging developed from the innate limitations of planar ultrasound, including user-operator technical dependencies and complex anatomic spatial prerequisites. Additionally, ultrasound techniques and instrumentation have evolved towards expanding access amongst clinicians and patients. To that end, portability of ultrasound systems has become paramount. This has afforded growth into the point-of-care ultrasound and remote or tele-ultrasound arenas. In parallel, advanced applications of ultrasound imaging have arisen. These include high frequency superficial sonograms to diagnose dermatologic pathologies as well as various intra-cavitary or lesional interrogations by contrast-enhanced ultrasound. Properties such as real­time definition and ease-of-access have spumed procedural and interventional applications for vascular access. This narrative review provides an overview of these advances and potential future directions of ultrasound
