The major purposes of statistics are to help us understand and describe phenomena in our world and to help us draw reliable conclusions about those phenomena. Yet, for want of exposure to statistical theory and practice, it continues to be regarded as the Achilles heel by all concerned in the loop of research and publication. There are many different types of statistical analysis. Choosing the ...

Fast imaging methods and the availability of required hardware for magnetic resonance tomography (MRT) have significantly reduced acquisition times from about an hour down to several minutes or seconds. With this development over the last 20 years, magnetic resonance imaging (MRI) has become one of the most important instruments in clinical diagnosis. In recent years, the greatest progress in f...

We explore the lifting question in the context of cut-generating functions. Most of the prior literature on lifting for cut-generating functions focuses on which cut-generating functions have the unique lifting property. Here we develop a general theory for understanding how to do lifting for cut-generating functions which do not have the unique lifting property.

Discriminating against arsenate: Determination of the structure of periplasmic phosphate binding proteins at very high resolution provides the basis for understanding the high discrimination of bacteria against arsenate. The results complete our insight into earlier erroneous conclusions on the ability of certain bacteria to use arsenate instead of phosphate.
