Neutron Collimation With Microchannel Plates: Calibration of Existing Technology and Near

April 1, 2007
Author(s)
A S. Tremsin, Daniel S. Hussey, David L. Jacobson, Muhammad D. Arif, Robert Gregory Downing, W B. Feller, David F. Mildner
A new type of high performance and compact neutron collimator can be manufactured from Gd- or B-doped microchannel plates (MCPs). Structures only a few mm thick have very narrow rocking curves and high out-of-angle rejection ratios, as observed previously

Mutationism and the dual causation of evolutionary change

May 1, 2006
Author(s)
Arlin B. Stoltzfus
The rediscovery of Mendel's laws a century ago launched the science that William Bateson called "genetics," and led to a new view of evolution combining selection, particulate inheritance, and the newly characterized phenomenon of "mutation." This
