The paper presents an architecture for fast mode decision algorithm in H.264/AVC for 4x4 intra-prediction. This algorithm is based on the inherent symmetry existing in the spatial prediction modes. This algorithm gives a faster way of calculating sum of absolute differences (SADs) for all modes of intra prediction. So, a significant computational savings can be achieved. Synthesis results confi...

87 Progress in fluorescence imaging is enabling the study of biological events at unprecedented detail, thanks to novel microscopy techniques that provide imaging with nanoscale resolution. 3D imaging of living cells within intact tissues, organs, and whole animals, is accessible through multiphoton excitation. The remarkably rich photophysics of Fluorescent Proteins (FPs) makes them flexible e...

In this paper we present work to combine fixed priority scheduling with off-line schedule construction.It assumes a schedule has been constructed off-line for a set of tasks to meet their complex constraints.Our method takes the schedule and assigns the FPS attributes priority, offset, and period, to the tasks, such that their runtime FPS execution matches the off-line schedule.It does so by di...

Computational protein annotation methods occasionally introduce errors. False-positive (FP) errors are annotations that are mistakenly associated with a protein. Such false annotations introduce errors that may spread into databases through similarity with other proteins. We present a protein-clustering method that enables automatic separation of FP from true-positive hits. The method is based ...

We show that fluorescence lifetime is a powerful contrast mechanism that can enhance the whole-body imaging of fluorescent proteins (FPs), in the presence of background tissue autofluorescence (AF). The nonexponential AF decay is characterized from time-domain (TD) measurements on multiple nude mice and separated from the FP fluorescence using a linear fit to a priori basis functions. We illust...

Routine data from the Dutch Transition project on 236 027 episodes of care collected by 54 family physicians (FPs) for 93 297 patient years in their listed practices and classified with the International Classification of Primary Care, were used to analyse chronic alcohol abuse episodes of care in Dutch family practices. Data on 332 episodes are presented. In a subsample with a 4-year registrat...

BACKGROUND AND OBJECTIVES The Faces Pain Scale-Revised (FPS-R) and Color Analog Scale (CAS) are self-report pain scales commonly used in children but insufficiently validated in the emergency department setting. Our objectives were to determine the psychometric properties (convergent validity, discriminative validity, responsivity, and reliability) of the FPS-R and CAS, and to determine whether...

Aging-associated alterations of cellular functions have been implicated in various disorders including cancers. Due to difficulties in identifying aging cells in living tissues, most studies have focused on aging-associated changes in whole tissues or certain cell pools. Thus, it remains unclear what kinds of alterations accumulate in each cell during aging. While analyzing several mouse lines ...

BACKGROUND Prior studies have reported relatively low job satisfaction for general internists. We used data from a large US physician survey to assess correlates of satisfaction of general internists. METHODS The Physician Worklife Survey was mailed to a national random stratified sample of 5704 US physicians. General internists were assessed for their satisfaction, training, patient mix, wor...
