The ensemble Kalman filter (EnKF) has been used in weather forecasting to assimilate observations into weather models. In this study, we examine how effectively forecasts of a forest carbon cycle can be improved by assimilating observations with the EnKF. We used the EnKF to assimilate into the terrestrial ecosystem (TECO) model eight data sets collected at(More)
Most intronic micro-RNAs are coexpressed with their host genes, suggesting that they may play similar roles. The function of miR-483 remains unknown, although it is embedded in an intron of Igf2 gene, which is an activator of hepatocellular carcinoma proliferation. In the present study, we provide evidence that Igf2-derived miR-483 can induce proliferation(More)
The transition from liver fibrosis to hepatocellular carcinoma (HCC) has been suggested to be a continuous and developmental pathological process. MicroRNAs (miRNAs) are recently discovered molecules that regulate the expression of genes involved in liver disease. Many reports demonstrate that miR-483-5p and miR-483-3p, which originate from miR-483, are(More)
BACKGROUND AND PURPOSE There are currently no data on the relationship between admission pulse pressure (PP) level and short term clinical outcome among acute stroke patients in the Chinese population. We studied the association between admission PP and in-hospital death or dependency among acute stroke patients in Inner Mongolia, China. METHODS A total(More)
Ensemble size is critical to the efficiency and performance of the ensemble Kalman filter, but when the ensemble size is small, the Kalman gain generally cannot be well estimated. To reduce the negative effect of spurious correlations, a regularization process applied on either the covariance or the Kalman gain seems to be necessary. In this paper, we(More)
Image matting aims at extracting foreground from a given image by means of color and alpha estimation. An automatic matting method based on saliency detection was proposed in this paper, which takes the advantages of saliency detection as prior information instead of user interaction. After getting the saliency map, a cost function was constructed to obtain(More)
