201 Hansen, Charles D.Multidimensional transfer functions for interactive volume renderingAbstract-Most direct volume renderings produced today employ one-dimensional transfer functions which assign color and opacity to the volume based solely on the single scalar quantity which comprises the data set. Though they have not received widespread attention, multidimensional transfer function...2002-07
202 Liu, FengNanostressors and the nanomechanical response of a thin silicon film on an insulatorPseudomorphic three-dimensional Ge nanocrystals (quantum dots) grown on thin silicon-on-insulator substrates can induce significant bending of the silicon template layer that is local on the nanometer scale. We use molecular dynamics simulations and analytical models to confirm the local bending of...Nanostressors; Nanomechanical response; Thin silicon film2002-09
203 Lupton, John MarkNonequilibrium polariton dynamics in organic microcavitiesMicrocavities containing a J-aggregate forming organic dye were prepared in the strong-coupling regime. Changing the position of the neat organic films within the microcavity allows a tuning of the giant Rabi splitting observed. We set the Rabi splitting to 25 meV and study the thermal activation o...Nonequilibrium polariton dynamics; Organic microcavities; Optical microcavities; Rabi splitting; Light-matter interactions; Arrhenius activation2002-08
204 Wu, Yong-ShiOn gauge invariance of noncommutative Chern-Simons theoriesMotivated by possible applications to condensed matter systems, in this paper we construct U(N) noncommutative Chern-Simons (NCCS) action for a disc and for a double-layer geometry, respectively. In both cases, gauge invariance severely constrains the form of the NCCS action. In the first case, it ...2002-05
205 Lupton, John MarkOrigin of spectral broadening in amorphous π-conjugated amorphous semiconductorsWe present a study of the picosecond fluorescence dynamics of p-conjugated semiconducting organic dendrimers in the solid state. By varying the degree of branching within the dendrons, referred to as the dendrimer generation, a control of intermolecular spacing of the emissive core and therefore o...pi-conjugated polymers; pi-conjugated semiconductors; Spectral broadening; Solid state; Picosecond fluorescence dynamics2002-10
206 Vardeny, Zeev ValentinePhotoinduced quantum interference antiresonances in ∏-conjugated polymersWe observed photoinduced quantum interference antiresonances between several discrete infraredactive vibrations and the lower-polaron continuous absorption band in a series of p-conjugated polymer films having superior planar orders, where the polaron transition energy is relatively small. The phot...pi-conjugated polymers; Antiresonances; Fano-type antiresonances2002-05
207 Vardeny, Zeev ValentinePhotophysics of pristine and C60-doped disubstituted polyacetyleneUsing a variety of steady-state spectroscopies we studied the long-lived photoexcitations and electronic excited states of poly disubstituted acetylene (PDPA-nBu), the backbone structure of which is a disubstituted trans-polyacetylene, as well as PDPA-nBu/C60 blends. The cw spectroscopies include a...Photophysics; Pristine disubstituted polyacetylene; C60-doped disubstituted polyacetylene; pi-conjugated polymers; Photoexcitations; Electronic excited states2002-08
208 Gondolo, PaoloRecoil momentum spectrum in directional dark matter detectorsDirectional dark matter detectors will be able to record the recoil momentum spectrum of nuclei hit by dark matter WIMPs. We show that the recoil momentum spectrum is the Radon transform of the WIMP velocity distribution. This allows us to obtain analytic expressions for the recoil spectra of a va...Recoil momentum spectrum; Radon transform; WIMP; Weakly interacting massive particles; Velocity distribution2002-11
209 Wu, Yong-ShiRenormalization group equations and the Lifshitz point in noncommutative Landau-Ginsburg theoryA one-loop renormalization group (RG) analysis is performed for noncommutative Landau-Ginsburg theory in an arbitrary dimension. We adopt a modern version of the Wilsonian RG approach, in which a shell integration in momentum space bypasses the potential IR singularities due to UV-IR mixing. The mo...2002-02

213 Landesman, Margaret M.Saving yourself into the poor houseSense and Sensibility column: "Saving yourself into the poor house...Perhaps it might be a good thing, especially when thinking about life four or five years down the road, to look more closely at these tempting small "incremental expenditures" for "Big Deals."

214 Liu, FengSelf-assembly of three-dimensional metal islands: nonstrained versus strained islandsA theoretical model for the Volmer-Weber growth of three-dimensional metal islands is proposed, with a dipolar island edge-edge interaction. The existence of such an island edge effect makes the island shape dependent on island size. Furthermore, it induces a stable island size against coarsening, l...Self-assembly; Three dimensional islands; Metal islands; Nonstrained islands; Strained islands; Volmer-Weber growth2002-11
215 Liu, FengSelf-organized nanoscale pattern formation on vicinal Si(111) surfaces via a two-stage faceting transitionWe demonstrate a self-organized pattern formation on vicinal Si(111) surfaces that are miscut toward the [211] direction. All the patterns, consisting of a periodic array of alternating (7 X 7) reconstructed terraces and step-bunched facets, have the same periodicity and facet structure, independent...Vicinal Si(111); Nanoscale pattern formation; Two-stage; Faceting transition2002-02

But universalism, the rule of law, justice, pluralism, accountability, good governance, human rights these are all general variations on d...2002-09
217 Vardeny, Zeev ValentineSpin-dependent delayed luminescence from nongeminate pairs of polarons in ∏-conjugated polymersWe measured cw photoinduced absorption (PA) and spin- 1 2 PA- and photoluminescence detected magnetic resonance (PADMR and PLDMR, respectively) in films of two representative p-conjugated polymers; poly(phenylene-vinylene) and polythiophene. From the dependences of the polaron PA and PLDMR on the ...pi-conjugated polymers; Nongeminate pairs; Spin-dependent delayed luminescence; Photoinduced absorption; Poly(phenylene-vinylene)2002-12
218 Boehme, ChristophSpin-dependent recombination - an electronic readout mechanism for solid state quantum computersIt is shown that coherent spin motion of electron-hole pairs localized in band gap states of silicon can influence charge carrier recombination. Based on this effect, a readout concept for silicon based solid-state spin-quantum computers as proposed by Kane is suggested. The 31P quantum bit (qbit) i...Spin readout; qbit; Spin-dependent recombination2002-10
