76 Wu, Yong-ShiOn the Kadomtsev-Petviashvili hierarchy, Ŵ∞ algebra, and conformal SL(2,R)/U(1) model. II. The quantum caseThis article is devoted to constructing a quantum version of the famous Kadomtsev-Petviashvili (KP) hierarchy by deforming its second Hamiltonian structure, namely, the nonlinear W, algebra. This is achieved bx quantizing the conformal noncompact SL(2,R) k/ U(1) coset model, in which W, appears as ...Kadomtsev-Petviashvili hierarchy; Quantum charges; W-algebras1993

84 Morse, Michael DavidPhotodissociation measurements of bond dissociation energies: Ti?+, V?+, Co?+, and Co?+The bond dissociation energies of Ti2+, V+2 , Co+2, and Co: have been measured from the sudden onset of predissociation in the photodissociation spectra of these molecules, yielding values of D?(Ti+2)=2.435+0.002 eV, D?(V+2)=3.140?0.002 eV, D?(Co+2)=2.7651?0.001 eV, and D?(Co+3)=2.086?0.002 eV. Thes...1993
85 Millgram, ElijahPleasure in practical reasoningPractical reasoning often strikes philosophers as ungrounded. It seems to them that desires are to be justified by reasoning that proceeds from, inter alia, further desires, and these further desires are to be justified by reference to still further desires. Avoiding circularity and infinite regres...1993
86 Stevens, KennethThe post office experience: designing a large asynchronous chipThe Post Office is an asynchronous, 300,000 transistor, full-custom CMOS chip designed as the communication component for the Mayfly scalable parallel processor. Performance requirements led to the development of a design style which permits the design of sequential circuits operating under a rest...1993
87 Michell, NickPPL 1.2mu gallium arsenide cell setThe purpose of this note is to describe the 1.2/i gallium arsenide PPL cell set - not only what is included, but design decisions made along the way. The first section is an overview of the Umitations imposed by the use of gallium arsenide technology, the next section describes the trade-offs in des...Gallium arsenide cells; PPL cell set1993
88 Miller, Jan D.Preliminary evaluation of air-sparged hydrocyclone technology for scavenger flotation of Western phosphatesThe sedimentary western phosphate deposits of Idaho, Montana, Utah, and Wyoming tend to be calcareous and generally carry a significant amount of dolomite along with collophanite. In some cases, such as the Smokey Canyon Mine, Afton, Wyoming, the ore will also contain mudstone, and in this case the ...Collophanite; hydrosizer; scavenger concentrate1993
89 Miller, Joel StevenPressure dependence of magnetic ordering temperature for decamethylferrocenium tetracyanoethenideIt has been demonstrated that the linear-chain charge-transfer salt, decamethylferrocenium tetracyanoethanide (DMeFc) (TCNE), is a ferromagnet with a transition temperature of -4.8 K. This low-temperature 3D ordering has been attributed to a strong intrachain and a weak interchain interaction. To...Ferromagnetic; Transition; Antiferromagnetic1993
90 Couldwell, William T.Protein kinase C inhibitors suppress cell growth in established and low-passage glioma cell lines. a comparison between staurosporine and tamoxifenWE HAVE PREVIOUSLY demonstrated that the proliferation of established human glioma cell lines correlated with protein kinase C (PKC) activity and that a relatively selective PKC inhibitor, staurosporine, inhibits glioma cell proliferation.

99 Johnston, Susan S.Replacing challenging behavior: the role of communication interventionIT IS WIDELY accepted that all individuals communicate (National Joint Committee, 1992). Along with this acceptance, however, comes the acknowledgment that specific communication strategies emitted by learners may vary extensively.
