INTRODUCTION Stroke is a leading cause of disability in the United States (National Stroke Association, 1994). The Veterans Health Administration (VHA) of the Department of Veterans Affairs (VA) estimates that 15,000 veterans are hospitalized for stroke each year (VA HSR&D, 1997). Forty percent of stroke patients are left with moderate functional(More)
BACKGROUND AND AIMS With the expanding use of diagnostic and therapeutic radiological modalities in critically ill patients, doctors working in Intensive Care Units (ICUs) are increasingly exposed to ionizing radiation. This risk of radiation exposure occurs not only during bedside radiologic procedures, but also when ICU physicians accompany patients to(More)
Technology innovation is not just a result of funds invested in research and development of a firm; it is a culmination of long-standing investments in well-thought-out processes, plans, and strategies. The chapter aims to address these aspects of technological innovations. The innovation process is a unique one, and each firm has a different style of(More)
We review our work done to optimize the staggered conjugate gradient (CG) algorithm in the MILC code for use with the Intel Knights Landing (KNL) architecture. KNL is the second generation Intel Xeon Phi processor. It is capable of massive thread parallelism, data parallelism, and high on-board memory bandwidth and is being adopted in supercomputing centers(More)
Positron emission tomography (PET) has been in use for a few decades but with its fusion with computed tomography (CT) in 2001, the new PET/CT integrated system has become very popular and is now a key influential modality for patient management in oncology. However, along with its growing popularity, a growing concern of radiation safety among the(More)
Glomerular filtration rate (GFR) estimation by plasma sampling method is considered as the gold standard. However, this method is not widely used because the complex technique and cumbersome calculations coupled with the lack of availability of user-friendly software. The routinely used Serum Creatinine method (SrCrM) of GFR estimation also requires the use(More)
