Representing uncertainty when creating visualizations is becoming more indispensable to understand and analyze scientific data. Uncertainty may come from different sources, such as, ensembles of experiments or unavoidable information loss when performing data reduction. One natural model to represent uncertainty is to assume that each position in space(More)
I the past decade, the air quality of China has been drawing great concern in the face of the country's rapid economic development. Nowadays, suspended particulate matter (PM) is considered to be the most serious pollutant in the metropolitan areas around the world due to its adverse health effects, including cardiovascular diseases, respiratory irritation,(More)
This paper evaluates features of graph coloring algorithms implemented on graphics processing units (GPUs), comparing coloring heuristics and thread decompositions. As compared to prior work on graph coloring for other parallel architectures, we find that the large number of cores and relatively high global memory bandwidth of a GPU lead to different(More)
Uncoupling protein-3 (UCP3) expression has been shown to increase dramatically in response to muscular contraction, but the physiological significance of UCP3 upregulation is still elusive. In this study, UCP3 mRNA and protein expression were investigated along with mitochondrial respiratory function, reactive oxygen species (ROS) generation, and(More)
As one of the most prevalent chronic disorders, airway disease is a major cause of morbidity and mortality worldwide. In order to understand its underlying mechanisms and to enable assessment of therapeutic efficacy of a variety of possible interventions, noninvasive investigation of the airways in a large number of subjects is of great research interest.(More)
We examined an at-risk population in China, money boys (MBs), to evaluate their potential role for transmitting HIV and sexually transmitted infections (STIs). Data were collected from 418 MBs selected by time-location cluster sampling, using a self-administered computerized questionnaire and testing a small blood sample for HIV/STIs. One-third (32.1%) of(More)
Precise click prediction is one of the key components in the sponsored search system. Previous studies usually took advantage of two major kinds of information for click prediction, i.e., relevance information representing the similarity between ads and queries and historical click-through information representing users' previous preferences on the ads.(More)
High expression levels of the human sineoculis homeobox homolog 1 (SIX1) gene have been correlated with numerous human malignancies. The SIX1 protein is involved in chromatin reconstruction and gene transcription, and plays an important role in cell apoptosis. This study explores the role of SIX1 in tumor progression and in the prognostic evaluation of(More)
The physiological significance of cardiac mitochondrial uncoupling protein 2 (UCP2)-mediated uncoupling respiration in exercise is unknown. In the current study, mitochondrial respiratory function, UCP2 mRNA level, UCP2-mediated respiration (UCR), and reactive oxygen species (ROS) generation, as well as manganese superoxide dismutase (MnSOD) activity were(More)
Mitochondrial catastrophe can be the cause or consequence of apoptosis and is associated with a number of pathophysiological conditions. The exact relationship between mitochondrial catastrophe and caspase activation is not completely understood. Here we addressed the underlying mechanism, explaining how activated caspase could feedback to attack(More)
