While perennial in the research landscape, empirical work investigating second language (L2) study emotions has proliferated in the past ten years (Dewaele, 2019). Nevertheless, this article argues there is space for more holistic yet detailed, socia

We have investigated limited angle transmission tomography to estimate speed of sound (SOS) distributions for breast cancer detection. That requires both accurate delineations of major tissues, in this case by segmentation of prior B-mode images, and
