We made an MR-compatible brain slice holder that ensures that the images have the same location and orientation as the subsequent histologic sections. This device encloses the unfixed tissues, thus reducing the danger of exposure to pathogens. MR imaging time is saved by scanning selected slices rather than the whole brain; this technique is especially useful when brain sections at varying angl...

While GARCH models can well describe the dynamic changes of the volatility of financial time series, and capture the cluster and heteroscedasticity phenomena. At the beginning of ...
