Search for exclusive b-->u semileptonic decays of B mesons.
Using a sample of 935000 BB pairs collected with the CLEO-II detector at the Cornell Storage Ring, we have obtained upper limits on the branching ratios for the b→ul - υ#58 processes B - →ωl - υ#58, B - →ρ 0 l - υ#58, and B 0 →ρ + l - υ#58. The combined result using the relationships among the widths for these three modes is B(B - →ρ 0 l - υ#58)<(1.6-2.7)×10 -4 at 90% C. L., where the range of value to model dependence of the detection efficiencies. These measurements yield the limits |V ub /V cb |<0.08-0.13

MINOS near-detector coil design
The 980-ton MINOS near detector will be installed in the new NuMI near hall at 100m below grade at Fermilab. It will be assembled from 282 1-inch thick steel plates. The planes are made from low carbon (1006), hot rolled steel and are toroidally magnetized. Each plane will be hung by two 'ears', which are extensions of the octagonal plane structure, similar to the hanging files in a file drawer. The plates have a center-to-center spacing of 5.94 cm. This document has been prepared for the 8/99 Conceptual Design Review of the MINOS near detector coil. It's main goal is to provide a set of references to previous documents and to assemble various design drawings and engineering calculations that have not been included in previous technical memos. It also provides some background material relevant for the coil implementation. Much of the text for this document is edited from the MINOS Detectors Technical Design Report.

Search for B0 decays to two charged leptons.
We have searched for [ital B][sup 0] decays to two charged leptons and set 90% confidence level upper limits on the branching fractions: [ital B]([ital B][sup 0][r arrow][ital e][sup +][ital e][sup [minus]])[lt]5.9[times]10[sup [minus]6], [ital B]([ital B][sup 0][r arrow][mu][sup +][mu][sup [minus]])[lt]5.9[times]10[sup [minus]6], [ital B]([ital B][sup 0][r arrow][ital e][sup [plus minus]][mu][sup [minus plus]]) [lt]5.9[times]10[sup [minus]6], [ital B]([ital B][sup 0][r arrow][ital e][sup [plus minus]][tau][sup [minus plus]])[lt]5.3[times]10[sup [minus]4], and [ital B]([ital B][sup 0][r arrow][mu][sup [plus minus]][tau][sup [minus plus]])[lt]8.3[times]10[sup [minus]4].

Some Applications of the ADM Formalism
The ADM Formalism is discussed in the context of 2+1--dimensional gravity, uniting two areas of relativity theory in which Stanley Deser has been particularly active. For spacetimes with topology R x T^2 the partially reduced and fully reduced ADM formalism are related and quantized, and the role of "large diffeomorphisms" (the modular group) in the quantum theory is illustrated.

Classical and quantum geometry of moduli spaces in three-dimensional gravity
We describe some results concerning the phase space of 3-dimensional Einstein gravity when space is a torus and with negative cosmological constant. The approach uses the holonomy matrices of flat SL(2,R) connections on the torus to parametrise the geometry. After quantization, these matrices acquire noncommuting entries, in such a way that they satisfy q-commutation relations and exhibit interesting geometrical properties. In particular they lead to a quantization of the Goldman bracket.
