The regulatory mechanism of sarcomeric activity has not been fully clarified yet because of its complex and cooperative nature, which involves both Ca(2+) and cross-bridge binding to the thin filament. To reveal the mechanism of regulation mediated by the cross-bridges, separately from the effect of Ca(2+), we investigated the force-sarcomere length (SL) relationship in rabbit skeletal myofibri...

We present a method to address the challenging problem of segmentation of multi-modality isointense infant brain MR images into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF). Our method is based on contextguided, multi-stream fully convolutional networks (FCN), which after training, can directly map a whole volumetric data to its volume-wise labels. In order to alleviate th...

This paper presents a fast method for computing whether or not two convex polygons in three dimensions intersect. The test relies exclusively on the sign of 4 4 determinants. The source code is available online.

Some techniques which average multiple AMSR satellite data passes into daily sets create images with diminished temporal resolution. This results from averaging data of multiple overlapping passes separated by many hours. Overlap can be reduced by instead grouping data according to local time of day. This new method maximizes temporal resolution by decreasing both the number and the temporal va...
