551 Sperry, John S.Anatomy of the palm Rhapis excelsa, VIII. Vessel network and vessel-length distribution in the stemTHE CONCEPT of the vessel, a conducting unit consisting of a series of vessel elements lined up end to end, has been known for well over a century (e.g., Hartig, 1878). The fact that vessels are of limited length is of considerable functional importance. If a vessel is damaged (for example, by an in...Palm stems; Palm stem anatomy; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column1982
552 Chuaqui, Miguel BasimAncient wing for solo fluteArchaeopteryx (Ancient Wing) was a prehistoric animal, presumably the "missing link" between reptiles and birds. I portrayed the dual nature of the animal by writing music that represents it both as a lizard-like motionless reptile, suddenly scuttling through the forest, as well as an ungainly bird,...1998
553 Bargteil, Adam WadeAnimation of deformable bodies with quadratic bézier finite elementsIn this article, we investigate the use of quadratic finite elements for graphical animation of deformable bodies.We consider both integrating quadratic elements with conventional linear elements to achieve a computationally efficient adaptive-degree simulation framework as well as wholly quadratic ...2014-01-01
554 Miller, Jan D.Anisotropic character of talc surfaces as revealed by streaming potential measurements, atomic force microscopy, and molecular dynamics simulationsA study of the interfacial properties of the basal plane and the edge surfaces of talc is described in this paper. The isoelectric-point measured at the two different crystallographic planes by the streaming potential method was found to be similar and exists at about pH 3.0. In the case of the edg...Streaming potential; Scanning electron microscope; Atomic force microscope2006

556 Tasdizen, Tolga; Whitaker, Ross T.Anisotropic diffusion of surface normals for feature preserving surface reconstructionFor 3D surface reconstruction problems with noisy and incomplete range data measured from complex scenes with arbitrary topologies, a low-level representation, such as level set surfaces, is used.

559 Liu, FengAnisotropic strain enhanced hydrogen solubility in bcc metals: the independence on the sign of strainWhen an impurity is doped in a solid, it inevitably induces a local stress, tending to expand or contract the lattice. Consequently, strain can be applied to change the solubility of impurity in a solid. Generally, the solubility responds to strain ‘‘monotonically,'' increasing (decreasing) with...2012-01-01

561 Baehr, WolfgangAnnotation and analysis of 10,000 expressed sequence tags from 3 mouse eye cDNA librariesBACKGROUND: As a biomarker of cellular activities, the transcriptome of a specific tissue or cell type during development and disease is of great biomedical interest. We have generated and analyzed 10,000 expressed sequence tags (ESTs) from three mouse eye tissue cDNA libraries: embryonic day 15.5 (...Cluster Analysis; DNA, Complementary; Gene Expression Profiling2003
562 Gondolo, PaoloAnnual modulation of dark matter in the presence of streamsIn addition to a smooth component of weakly interacting massive particle (WIMP) dark matter in galaxies, there may be streams of material; the effects of WIMP streams on direct detection experiments is examined in this paper. The contribution to the count rate due to the stream cuts off at some char...WIMP streams; Weakly interacting massive particles; Cutoff energy; Halo models; Sagittarius dwarf galaxy; Recoil energy; Sgr stream2006-08
563 Miller, Joel Steven; Epstein, Arthur J.Anomalous charge transport phenomena in the molecular-based magnet V(TCNE)x.y(solvent)We present charge transport studies on recently developed molecular-based magnets V(TCNE)x. y(solvent) (TCNE= tetracyanoethylene) which show local magnetic ordering at temperatures, T, as high as 400 K. V(TCNE), .y(solvent) prepared from the solvent CH2Cl2 has o(300 K) - 10-3 S/cm, and that prepar...Frequency; Conductivity; Spin1993
564 Vardeny, Zeev Valentine; Raikh, Mikhail E.Anomalous coherent backscattering of light from opal photonic crystalsWe studied coherent backscattering (CBS) of light from opal photonic crystals with incomplete band gaps. We observed a dramatic broadening of the CBS cone for incident angles close to the Bragg condition in the crystals. We modify the conventional CBS theory to incorporate Bragg attenuation resultin...Coherent backscattering; Bragg condition2001-05
565 Miller, Joel Steven; Epstein, Arthur J.Anomalous magnetoresistance in high-temperature organic-based magnetic seminconducting V(TCNE)x filmsAnomalous positive magnetoresistance (MR) in high temperature organic-based magnet V(TCNE)x (TCNE=tetracynoethylene) thin films is reported. MR increases linearly with applied magnetic field and shows a maximum at the ferrimagnetic ordering temperature. The suggested roles of oppositely spin pola...Spin; Ferrimagnetic; Resistance2003
566 Vardeny, Zeev ValentineAnomalous optical and ESR properties of doped polydiethynylsilanesThe optical, transport, and ESR properties of soluble conducting four-membered polydiethynylsilane heterocycles are described. The undoped one-dimensional gap is 2.0 eV in both films and solutions; no photoluminescence is observed.

567 Bedrov, Dmitro; Smith, Grant D.Anomalous pressure dependence of the structure factor in 1,4-polybutadiene melts: a molecular dynamics simulation studyNeutron scattering has shown the first diffraction peak in the structure factor of a 1,4-polybutadiene melt under compression to move to larger q values as expected but to decrease significantly in intensity. Simulations reveal that this behavior does not result from loss of structure in the polymer...Polymer melts; 1, 4-polybutadiene melts; Pressure; Structure factor2004-07

571 Mattis, Daniel C.Anomaly in spin-wave spectrum of magnetic metalsIt is pointed out that in the band theory of magnetism the magnons have frequencies comparable to the Fermi energy. Therefore, in the calculation of the magnon spectrum of iron, nickel, cobalt, etc., it is the time- or frequency-dependent response function of the electrons which is used, and this ...Magnetic metals1966-11
572 Morrow, CarolynAnother aspect of the fénix: Lope as writer of autosHispanists have frequently lamented the loss of a large number of the comedias of Lope de Vega while, proportionately, there may be greater cause for regret in the case of his autos. Texts of only forty-odd of these are known today - a number quite different from the four hundred which Juan Pérez ...1972
573 Davidson, Diane W.Ant-plant symbioses in Africa and the neotropics : history, biogeography and diversitySymbiotic ant-plant relationships afford an excellent opportunity to analyze the effects of both historical and ecological factors on the evolution of mutualisms. Occurring in tropical forests throughout the world, all myrmecophytic plants provide food and permanent housing to ants; the ants, in t...Ant-plant symbiosis; Africa; Neotropics; Myrmecophytes; Plant-ants1993
