Abstract We need to discuss our role as the concert master for our parallel programs. The proper orchestration of a parallel program is a thing of beauty—code running full speed without waiting for data, because we have arranged for all data to arrive and depart at the proper times. Code well-decomposed to keep the hardware maximally busy. It is the thing that dreams are made of!

Abstract We supercomputer architects often lament that we need to “feed the beast.” The phrase “feed the beast” refers to the “beast” of a computer we create when we use lots of parallelism, and feeding data to it becomes a key challenge to solve.

Abstract Vectors are collections of data. These can be useful because parallelism in our computers comes from collections of compute hardware, and data is often processed in related groupings (e.g., the color channels in an RGB pixel). Sound like a marriage made in heaven? It is so important, we’ll spend a chapter discussing the merits of vector types and how to utilize them. We will not dive into vectorization in this chapter, since that varies based on device type and implementations. Vectorization is covered in Chapters 10.1007/978-1-4842-5574-2_15 and 10.1007/978-1-4842-5574-2_16.

OBJECTIVE: The primary aim of this study was to determine if donepezil (a centrally acting cholinesterase inhibitor) improves measures of balance in persons with Parkinson’s disease (PD) compared to a placebo. BACKGROUND: Cholinesterase inhibitors have a positive impact on cognitive function in persons with PD and cognitive impairment or dementia.(Cochrane 2012) A small study also showed a reduction in falls in persons with PD without dementia.(Chung 2010) DESIGN/METHODS: This was a double-blind placebo controlled crossover study. Participants received 6 weeks of treatment with either placebo or donepezil, then a month washout, then another 6 weeks of treatment opposite to the first. Inclusion criteria were an MMSE>27 and balance impairment on clinical and posturography assessments (SOT <70). RESULTS: Ten participants’ data was used in the analysis. The mean age, UPDRS motor score, and PD disease duration were 69.6+5.9 years, 24+7, and 10.5+8 years at the initial visit. Mean scores on Stroop conflict time and trails B-A at baseline were 105+48s and 59+32s respectively. The mean composite SOT scores improved from 60+16 to 61+15 during the placebo phase and 59+11 to 62+14 during the donepezil phase. This change was not significant, p=0.7. However, in looking at the single conditions of the SOT, there was a statically significant change seen in condition 4 (Eyes Open, Sway referenced, p<0.03). Out of 10 participants, 4 improved more than 40[percnt], 4 improved mildly (between 15[percnt] and 30[percnt]), and 2 didn’t show improvements in C4 during the active phase of the study. In addition, there was a significant correlation between improvement in cognitive performance and balance, r=0.8, p=0.001. CONCLUSION:In this pilot study there was statistically significant improvement in one component of the SOT. A subset of patients appeared to have an improvement in balance. It appears that improvements in balance and executive functions are related.

In previous chapters we have seen how system-level virtual prototypes get created and how they are often partitioned into pieces intended to be implemented as either software or hardware. This partitioning was done to manage costs and performance and to optimize many other attributes of the system. For the parts of the system intended to be hardware, several choices still remain. It is possible that those functionalities can be implemented using off-the-shelf components, such as processors or DSPs, or as components that require small extensions in order to meet the necessary requirements, such as configurable and extensible processors. It is likely that there will be a few components for which dedicated custom hardware is required and we now need to refine those models in ways that make them more amenable to the transformation process that is often called behavioral synthesis or high-level synthesis.

P harmaceutical and nutrient interactions have been moderately studied yet often ignored by health care professionals. Many extensively prescribed drugs can lead to decreased absorption or increased excretion of many necessary vitamins, minerals, and amino acids. These drugs may also alter biochemical pathways necessary for proper utilization of nutrients. According to the Centers for Disease Control and Prevention (CDC), the number of adults ages 55–64 taking at least one pharmaceutical in the previous month rose from 62 percent in 1988–1994 to 73 percent in 1999–2002.1 The large number of individuals taking pharmaceuticals suggests that the potential for drug–nutrient interactions is substantial and growing. Owing to the vast number of pharmaceuticals on the market, this article is limited to a select group of commonly prescribed medications.

Of all the skeletons in the national closet, lynching has received but scant attention from historians and the public alike. Despite its long and widespread presence in American life and its use as a form of social and political control, scholarly studies of lynching remain relatively few and far between. Moreover, as some early-twentieth-century lynchings— with their horrific mutilations and the burning alive of their victims—are some of the most barbaric acts ever to occur in the United States, it is hardly surprising that many Americans would just as soon see such an unsettling part of our past be forgotten altogether. But there have also been some notable recent efforts to shed light on lynching. An exhibition of James Allen's remarkable collection of lynching photographs and postcards—published under the title Without Sanctuary (2000)—drew record crowds in Manhattan and two in-depth articles in the New York Times. New books on...

Abstract A 2.4 in. by 2.4 in. TFT LCD is presented with an embedded 60×60 array of a‐Si photo sensors, for use as a high performance touch‐enabled LCD with low cost. In the shadow mode the optical touch screen operates with finger or stylus input under ambient lighting conditions from 50 lux to 50 klux.

Oral doxepin rinse has been reported to provide pain relief in patients with oral mucosal lesions due to cancer or cancer therapy. The purpose of this study was to assess the anesthetic effect of doxepin oral rinse in normal subjects to identify the duration of effect and to contrast the anesthetic effect with reported pain relief in patients with oral mucosal lesions. Normal volunteers were provided a solution of doxepin (5 mg/mL) for oral rinsing. Oral numbness and adverse effects were recorded for a period of 4 h after rinsing. Doxepin rinse resulted in mucosal anesthesia in all subjects. Sedation/fatigue was reported in four of seven subjects. There were no taste complaints and no nausea reported. The limited duration of numbness/anesthesia in normal subjects compared with prior studies showing pain relief for more than 3 h in patients with mucosal lesions, suggests that the extended duration of pain relief in patients was due to analgesic effects rather than anesthetic effects. The majority of normal subjects reported sedation after use, but this was less common in patients with mucosal lesions.
