227 Newman, LexRocking the foundations of cartesian knowledge: critical notice of Janet Broughton, descartes's method of doubtJanet Broughton's Descartes's Method of Doubt†1 is a systematic study of the role of doubt in Descartes's epistemology. The book has two parts. Part 1 focuses on the development of doubt in the First Meditation, exploring such topics as the motivation behind methodic doubt; the targeted audience...Super-indubitables; Canonical circularity; Clear and distinct truths'2004-01
228 Moon, Ann M.; Capecchi, Mario R.Roles of Fgf4 and Fgf8 in limb bud initiation and outgrowth.Although numerous molecules required for limb bud formation have recently been identified, the molecular pathways that initiate this process and ensure that limb formation occurs at specific axial positions have yet to be fully elucidated. Based on experiments in the chick, Fgf8 expression in the in...Animals; Apoptosis; Forelimb; Gene Expression Regulation, Developmental; High Mobility Group Proteins; Hindlimb; In Situ Hybridization; Mesoderm; Mice, Mutant Strains; Trans-Activators2004-09
229 Liu, FengSelf-organized quantum-wire lattice via step flow growth of a short-period superlatticeWe develop a theoretical model for step flow growth of multilayer films, taking into account the interlayer step-step interaction induced by misfit strain.We apply the model to simulate the growth of strain-compensated short-period superlattices. Step-bunch ordering improves in successive layers, le...Quantum-wire lattice; Short-period superlattice; Step flow growth2004-06
230 Vardeny, Zeev ValentineSpectroscopic study of spin-dependent exciton formation rates in ∏-conjugated semiconductors: comparison with electroluminescence techniquesIt has been found in recent measurements that the singlet-to-triplet exciton ratio in organic light-emitting diodes (OLEDs) is larger than expected from spin degeneracy, and that singlet excitons form at a larger rate than triplets. We employed the technique of optically detected magnetic resonance...Spin-dependent exciton formation; pi-conjugated polymers2004-12
231 Mishchenko, EugeneSpin current and polarization in impure two-dimensional electron systems with spin-orbit couplingWe derive the transport equations for two-dimensional electron systems with Rashba spin-orbit interaction and short-range spin-independent disorder. In the limit of slow spatial variations, we obtain coupled diffusion equations for the electron density and spin. Using these equations we calculate el...Spin-orbit coupling; Spin current2004-11
232 Mishchenko, EugeneSpin detection in quantum dots by electric currentsWe develop a theoretical description of transport through quantum dots connected to reservoirs via spin-polarized ballistic contacts. Rate equations account for spin accumulation inside the dot, electron-electron interactions, and stochastic fluctuations. It is shown that both the ac response (admi...Spin detection2004-02
233 Liu, FengStrain effect on adatom binding and diffusion in homo- and heteroepitaxies of Si and Ge on (001) SurfacesStrain dependence of adatom binding energies and diffusion barriers in homo- and heteroepitaxies of Si and Ge on s001d surface has been studied using first-principles calculations. In general, Si adatom binding energies and diffusion barriers are larger on Sis001d and Ges001d surfaces than a Ge ada...Strain effect; Adatom binding; Adatom diffusion; Adatoms; Heteroepitaxies; Homoepitaxies; (001) surfaces; Si; Ge2004-10
234 Hansen, Charles D.; Whitaker, Ross T.Streaming narrow-band algorithm: interactive computation and visualization of level setsAbstract-Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization and computer graphics for applications such as segmentation, surface processing, and physically-based modeling. Their usefulness has been limited, however, by their high computa...2004-07

237 Liu, FengTheory of equilibrium shape of an anisotropically strained island: thermodynamic limits for growth of nanowiresUsing continuum elastic theory, we show that strain anisotropy removes the shape instability existing for an isotropically strained island. An anistropically strained island has always an anisotropic shape, elongating along the less-strained direction and adopting a narrow width in the more-strain...Strained islands; Equilibrium shape; Growth; Thermodynamic limits2004-11
238 Gerton, JordanTip-enhanced fluorescence microscopy at 10 nanometer resolutionWe demonstrate unambiguously that the field enhancement near the apex of a laser-illuminated silicon tip decays according to a power law that is moderated by a single parameter characterizing the tip sharpness. Oscillating the probe in intermittent contact with a semiconductor nanocrystal strongly...2004-10
239 DeTar, CarletonTopological susceptibility in staggered fermion chiral perturbation theoryThe topological susceptibility of the vacuum in quantum chromodynamics has been simulated numerically using the Asqtad improved staggered fermion formalism. At nonzero lattice spacing, the residual fermion doublers (fermion tastes) in the staggered fermion formalism give contributions to the suscept...Staggered fermions; Chiral perturbation2004-10
240 Vardeny, Zeev ValentineUltrafast spectroscopy of excitons in single-walled carbon nanotubesWe studied the femtosecond dynamics of photoexcitations in films containing semiconducting and metallic single-walled carbon nanotubes (SWNTs), using various pump-probe wavelengths and intensities.We found that confined excitons and charge carriers with subpicosecond dynamics dominate the ultrafas...Ultrafast spectroscopy; Excitons; Single-walled carbon nanotubes; SWNT2004-01
241 White, Paul H.Validation, persuasion and recycling: capitalizing on the social ecology of newspaper use.Two experiments used clinical validation to increase scrutiny of messages posted in public settings. The first experiment used a 2 (validation: no/yes) × 2 (persuasion: none/"it is important") factorial design to develop messages about newspaper recycling. The prompt (no validation/no persuasion) h...Recycling; Social Ecology; Newspapers; Social psychology2004-09
242 Gondolo, PaoloVariable stars toward the bulge of M 31: the AGAPE catalogueWe present the AGAPE astrometric and photometric catalogue of 1579 variable stars in a 14' × 10' field centred on M 31. This work is the first survey devoted to variable stars in the bulge of M 31.

247 Olivera, Baldomero M.; McIntosh, J. Michael; Hillyard, David R.A-superfamily of conotoxins: structural and functional divergenceThe generation of functional novelty in proteins encoded by a gene superfamily is seldom well documented.
