The STI CELL processor introduces pioneering solutions in processor architecture. At the same time it presents new challenges for the development of numerical algorithms. One is effective exploitation of the differential between the speed of single and double precision arithmetic; the other is efficient parallelization between the short vector SIMD cores. In this work, the first challenge is ad...

Despite evidence for the existence of dark matter (DM) from very high and low redshifts, a moderate amount DM particle decay remains valid possibility. This includes both models with long-lived yet unstable particles or mixed scenarios where only small fraction is allowed to decay. In this paper, we investigate how decaying into radiation affect non-linear structure formation. We look at power ...

Where books cite their purpose in the title, preface, or introduction, an image "makes no attempt to tell us what it is about" (Besser, 1990, p. 788). Besser also notes concern with text retrieval systems and relevancy problems of poor recall and precision: "text retrieval systems can achieve a sixty percent precision rate at best [6 out of 10 items retrieved are relevant to a user's query] but...

The purpose of this study was to evaluate a technique known as collaborative assessment considering students' and faculty members' perceptions of the value and utility of this approach. Twenty-eight dental hygiene students took eight individual assessments (quizzes) immediately followed by completion of the same assessment in a five-member peer group as part of a didactic dental hygiene course....

High tibial osteotomy (HTO) is an established treatment option for isolated medial osteoarthritis in young and active patients. One important factor for success of this procedure is the degree of correction of the weight-bearing line. Computer-assisted navigation systems are believed to improve the precision of axis correction through intraoperative real-time monitoring. This study investigates...

OBJECTIVE To examine the effect of a change in U.S. Preventive Services Task Force (USPSTF) screening guidelines on mammography rates in the United States. PRINCIPAL FINDINGS In 2010, the year following the change in guidelines, 12-month mammography prevalence among women aged 40-49 years fell by 2.09 percentage points (95 percent confidence interval [CI]: -2.87 to -1.31) from 54.63 percent i...

The effect that the aging process has on recognition performance was studied using a hierarchy of 1-pair, 2-pair, 3-pair, and 4-pair dichotic digits (1, 2, 3, 4, 5, 6, 8, 9, and 10, male speaker). Two groups of right-handed subjects were studied: 20 adults < 30 years of age with normal hearing and 20 adults 60-75 years with mild-to-moderate hearing loss. Each of the multipaired sets contained t...
