Several of the concepts of sequence-stratigraphic models were tested by experiments in a
large flume. Using different gradients for successive runs, a physical model of a fluvial …

Abdominal organ segmentation is highly desirable but difficult, due to large differences
between patients and to overlapping grey-scale values of the various tissue types. The first step …

Myocardial perfusion imaging with SPECT remains critically important for diagnosing, assessing,
and evaluating treatment of coronary artery disease. However, conventional rotational …

As part of our ongoing efforts to identify novel ligands for the metabotropic glutamate 2 and
