Studies of Charm Mixing and CPV

LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for direct and indirect CP violation in charm and to measure $D^0$ mixing parameters. Preliminary measurements from several decay modes are presented, with complementary time-dependent and time-integrated analyses.Comment: Presented at The Meeting of the American Physical Society, Division of Particles and Fields,Santa Cruz, California, August 13-17, 201

On four species of Copepoda new to Chesapeake Bay, with a description of a new variety of Paracalanus crassirostris Dahl

At this time, four additional species, unreported by Wilson [1932], can be added to the list of those species to be found within the limits of the bay. These are Acartia tonsa Dana, Cyclops vernalis Fischer, Diaptomus spatulocrenatus Pearse, and Paracalanus crassirostris Dahl var. nudus nov. The specimens from which identifications were made were collected by means of Clarke-Bumpus nets, in use on the motor ship "Mahatru.

Electromagnetic compatibility overview

An assessment of the electromagnetic compatibility impact of the Satellite Power System is discussed. The discussion is divided into two parts: determination of the emission expected from SPS including their spatial and spectral distributions, and evaluation of the impact of such emissions on electromagnetic systems including considerations of means for mitigating effects

A study of the crab pot as a fishing gear

The crab pot as a fishing gear was introduced in Maryland waters, following some years of greatly expanded use in Virginia, during the 1939 season, and was widely used during 1940. The 1941 session of the Maryland Legislature, however, illegalized the crab pot. Since that time the device has been given up almost entirely by Maryland fishermen, its attempted use in a commercial way having persisted in diminishing numbers in only one region of the state

Gauss-Bonnet Brane World Gravity with a Scalar Field

The effective four-dimensional, linearised gravity of a brane world model with one extra dimension and a single brane is analysed. The model includes higher order curvature terms (such as the Gauss-Bonnet term) and a conformally coupled scalar field. Large and small distance gravitational laws are derived. In contrast to the corresponding Einstein gravity models, it is possible to obtain solutions with localised gravity which are compatible with observations. Solutions with non-standard large distance Newtonian potentials are also described.Comment: To appear in the proceedings of Phi in the Sky: The Quest for Cosmological Scalar Fields, Porto, Portugal 8-10 July 2004. 6 page
