    Hobart, David B.; Merola, Joseph S. (International Union of Crystallography, 2013-04-13)
    The title complex salt, (C12H16NO2)[PdCl2(C12H14NO2)], is of interest with respect to organic and organometallic catalysis. The compound crystallizes as very small orange–red irregular prisms and the asymmetric unit contains ...
  • Saddles, arrows, and spirals: Deterministic trajectories in cyclic competition of four species 

    Durney, C. H.; Case, S. O.; Pleimling, M.; Zia, R. K. P. (American Physical Society, 2011-05-09)
    Population dynamics in systems composed of cyclically competing species has been of increasing interest recently. Here we investigate a system with four or more species. Using mean field theory, we study in detail the ...
  • Scalings for fragments produced from drop breakup in shear flow with inertia 

    Y. Y. Renardy; V. Cristini (American Institute of Physics, 2001-08)
    When a drop is sheared in a matrix liquid, the largest daughter drops are produced by elongative end pinching. The daughter drop size is found to scale with the critical drop size that would occur under the same flow ...
  • Scanning holographic microscopy with resolution exceeding the Rayleigh limit of the objective by superposition of off-axis holograms 

    Indebetouw, G.; Tada, Y.; Rosen, J.; Brooker, G. (Optical Society of America, 2007-02)
    We present what we believe to be a new application of scanning holographic microscopy to superresolution. Spatial resolution exceeding the Rayleigh limit of the objective is obtained by digital coherent addition of the ...
  • Scanning near-field optical microscopy utilizing silicon nitride probe photoluminescence 

    Lulevich, V.; Ducker, W. A. (AIP Publishing, 2005-11)
    We describe a simple method for performing high-resolution scanning near-field optical microscopy (SNOM). A commercial Si3N4 tip is illuminated by an intense light source, which causes the tip to emit redshifted (inelastically ...
  • scattering and inverse scattering in one-dimensional nonhomogeneous media 

    Aktosun, T.; Klaus, M.; Vandermee, C. (AIP Publishing, 1992-05)
    The wave propagation in a one-dimensional nonhomogeneous medium is considered, where the wave speed and the restoring force depend on location. In the frequency domain this is equivalent to the Schrodinger equation d2-psi/dx2 ...
  • scattering kernels for the muon diffusion equation 

    Rusjan, E.; Zweifel, P. F. (American Physical Society, 1988-08)
    Diffusion of muonic hydrogen atoms in gaseous hydrogen is studied. Scattering kernels are derived from the kinematics of an inelastic binary collision. The effect of rotations of the hydrogen molecules is treated by defining ...
  • scattering of two coherent beams by multiple centers 

    Li, M. C. (American Physical Society, 1974-09)
    This is a continuation in the theoretical study of scattering initiated by two coherent beams. Here the scattering by multiple independent centers is discussed. The presence of these centers involves some problems, which ...
  • scatterings initiated by two coherent beams 

    Li, M. C. (American Physical Society, 1974-04)
    A theory, which exhibits the characteristic features of scatterings initiated by two coherent beams, is discussed in the present paper. We show that the imaginary part of the scattering amplitude is an experimentally ...
  • Science and Values for a Finite Planet 

    Cairns, John (Asian Journal of Experimental Sciences, 2014-01-22)
    Exponential population growth on a finite planet means less resources per capita, and humankind is dependent upon the resources of the biospheric life support system for survival. However, humankind has acted, in the past, ...
  • Scientists, Time Management, and the Global Environmental Crisis 

    Cairns, John (Science and Society, 2014-01-22)
    The 21st century environmental crisis is vastly different from any other in human history. All the major components of the crisis are caused by humankind. With the largest human population ever on finite Earth, global ...
  • Search for massive neutrinos in the decay pi -> e nu 

    Aoki, M.; Blecher, M.; Bryman, D. A.; Chen, S.; Ding, M.; Doria, L.; Gumplinger, P.; Hurst, C.; Hussein, A.; Igarashi, Y.; Ito, N.; Kettell, S. H.; Kurchaninov, L.; Littenberg, L.; Malbrunot, C.; Numao, T.; Poutissou, R.; Sher, A.; Sullivan, T.; Vavilov, D.; Yamada, K.; Yoshida, M.; Pienu Collaboration (American Physical Society, 2011-09-06)
    Evidence of massive neutrinos in the pi(+) -> e(+)nu decay spectrum was sought with the background pi(+) -> mu(+) -> e(+) decay chain highly suppressed. Upper limits (90% C. L.) on the neutrino mixing matrix element vertical ...
  • Searching for the physiological mechanism of density dependence: Does corticosterone regulate tadpole responses to density? 

    Belden, L. K.; Rubbo, M. J.; Wingfield, J. C.; Kiesecker, J. M. (University of Chicago Press, 2007-07)
    Density-dependent population regulation is important in many natural populations, and in those populations, high population density is a likely stressor. In amphibians, previous laboratory studies with tadpoles suggest ...
  • Seasonal controls on snow distribution and aerial ablation at the snow-patch and landscape scales, McMurdo Dry Valleys, Antarctica 

    Eveland, J. W.; Gooseff, M. N.; Lampkin, D. J.; Barrett, J. E.; Takacs-Vesbach, C. D. (Copernicus Publications, 2013)
    Accumulated snow in the McMurdo Dry Valleys, while limited, has great ecological significance to subnivian soil environments. Though sublimation dominates the ablation process in this region, measurable increases in soil ...
  • Self-Assembly of Chiral Tubules 

    Cheng, Shengfeng; Stevens, Mark J. (The Royal Society of Chemistry, 2013-11-26)
    The efficient and controlled assembly of complex structures from macromolecular building blocks is a critical open question in both biological systems and nanoscience. Using molecular dynamics simulations we study the ...
