Contrast values estimated from temporal statistics is used for laser speckle contrast analysis (LASCA) of cortical blood flow and perfusion. Using temporal statistics, we are able to reliably estimate the blood flow and perfusion by processing only a selected number of pixels from the raw speckle images. For the number of frames (N > 6) for estimating the(More)
The aim of this study is to propose a new sensory evaluation method of tea liquor. Sensory data are usually expressed with linguistic terms, which are more suitable than crisp numbers under this situation. The proposed evaluation method firstly transforms the linguistic terms into triangular fuzzy numbers and then develops an evaluation method based on the(More)
The subtropical evergreen broadleaved forest (STEBF) in China is globally one of the most diverse and biologically important forest systems. There has been a long-term debate whether this region was affected dramatically during Pleistocene glaciation and deglaciation cycles, e.g., in terms of range dimensions and changes in species richness. Here we report(More)
