We have developed a rapid, minimally-contacting, method of collecting sample material from regolith-bearing surfaces of solar system bodies using gas flow to entrain particles and direct them toward collection cavities. Because it can be implemented in a brief, pogo-style interaction with a surface, it is termed the Touch-And-Go Sample Acquisition Mechanism(More)
We measured signiÞcant variation in the instantaneous growth rates for varroa mites, Varroa destructor (Anderson & Trueman) from 1993 to 2002 in Baton Rouge, LA. Mite population growth was monitored in colonies of honey bees, Apis mellifera L., with queens from miscellaneous U.S. sources that had not been selectively bred for varroa resistance.Mite(More)
The image structure produced by a periodic hexagonal pattern of mirror surface undulations has been analyzed. Such undulations form a two-dimensional phase grating that can result from the polishing of honeycomb mirrors or, for example, meniscus mirrors with a hexagonal pattern of axial supports. For monochromatic light of wavelength lambda, undulations(More)
A case is presented for compelling physics at a high luminosity RHIC II collider. A comprehensive new detector system is introduced to address this physics. The experimental focus is on detailed jet tomography of the quark gluon plasma (QGP), measuring gluon saturation in the nucleus, investigating the color glass condensate, measuring effects of the QCD(More)
