This initiative applies to a specific group of scholars – those working on post-baccalaureate degrees. The Riecker Fund will annually finance one or two University of Michigan graduate students, who may engage in research in one of two ways: They may join one of the Center’s own ongoing project teams, or they may work with advisors within their own academic disciplines. Either way, the Fund, an...

We discuss some of the cosmological consequences of a late-time ( z 5 lo3) phase transition which produces light domain walls. The observed peculiar velocity field of the Universe and the observed isotropy of the microwave background radiation severely constrain the wall surface density (= a) in such a scenario: Go 5 10-4H~ (Ho is the present value of the Hubble parameter). The most interesting...

A comprehensive review and study of the rich dinosaur track record of the Tremp Formation in the southern Pyrenees of Spain (Southwestern Europe) shows a unique succession of footprint localities prior to the end-Cretaceous mass extinction event. A description of some 30 new tracksites and data on sedimentary environments, track occurrence and preservation, ichnology and chronostratigraphy are ...

We assemble a few remarks on the supergravity solution of hep-th/0007191, whose UV asymptotic form was previously found in hep-th/0002159. First, by normalizing the R-R fluxes, we compare the logarithmic flow of couplings in supergravity with that in field theory, and find exact agreement. We also write the 3-form field strength G3 = F3 − τH3 present in the solution in a manifestly SO(4) invari...

H amlet is reading a magazine. His eye is caught by an advertisement for the Great Dane sword. The ad pictures Fortinbras ra is i~~g the sword in battle. The ad proclaims, "10 Reasons Why the Great Dane Outperforms Its Competitors!" The ad continues, "Reason #I: Because of its sharper blade, the Great Dane kills fa~ter and more decisively." Hamlet, who had never heard of the Great Dane before, ...

A continuous recording of landslide displacements is often required in order to better understand the complex relationship between the triggering factors and the dynamics of the movement. In this paper, we discuss the performance of the borehole wire extensometer and the interpretation of its results. The analysis for the case of a translational slide shows that the displacements measured with ...

The CELESTE experiment uses the heliostats of an old solar farm in the French Pyrenees to detect gamma ray air showers by the atmospheric Cerenkov technique. CELESTE has been operating since November 1999 with an array of 40 heliostats fully instrumented with 1GHz flash ADCs. Significant advances have been made in the detector simulations and in the data analysis techniques. We report here on r...
