      Benczik, I. J.; Karolyi, G.; Scheuring, I.; Tel, T. (American Institute of Physics, 2006-12)
      We investigate the dynamics of inertial particles immersed in open chaotic flows. We consider the generic problem of competition between different species, e.g., phytoplankton populations in oceans. The strong influence ...

    • Coherent spatial-filtering with simulated input 

      Fujii, H.; Almeida, S. P. (Optical Society of America, 1979-11)
      A disadvantage of a well-tuned matched filter is partly overcome in recognizing biological species, i.e., algae. A simplified input pattern is prepared which simulates a given species. The matched spatial filter for this ...

      Rondoni, L.; Zweifel, P. F. (American Physical Society, 1991-07)
      Transport of muonic deuterium atoms in a slab of thickness d filled with a molecular deuterium gas is described by means of the multiple-collision expansion in the framework of a time-dependent theory. The relevant expressions ...

      Indebetouw, G. (Optical Society of America, 1979-10)
      An incoherent optical processing technique for color coding the spatial frequency content of an input is described. Experimental results and comparison with the output of a coherent filtering system are discussed. Possible ...
    • Comment on "Evidence for Narrow Baryon Resonances in Inelastic ρρ Scattering" 

      L'Vov, A. I.; Workman, Ronald L. (American Physical Society, 1998-08-10)
      In a recent Letter [1], Tatischeff et al. claimed evidence for three neutral baryon resonances N* between the nucleon and the Δ(1232). Two of these have masses M = 1004 and 1044 MeV below mN ...
    • Comment on "First-principles treatments of electron transport properties for nanoscale junctions" 

      Lang, N. D.; Di Ventra, M. (American Physical Society, 2003-10)
      The use of a jellium model for the electrodes gives a good account of the conductance of a gold nanowire linking two metallic electrodes. The statement to the contrary in the recent paper of Fujimoto and Hirose [Phys. Rev. ...
    • Comment on the Dispersion Relations used to Calculate Δρ 

      Takeuchi, Tatsu; Grant, Aaron K.; Worah. Mihir (American Physical Soc, 1995-06-01)
      We use the operator product expansion (OPE) to show that nonperturbative QCD corrections to Δρ can be calculated using unsubtracted dispersion relations for either the transverse or the longitudinal vacuum polarization ...
    • Comparison of the calorimetric and kinematic methods of neutrino energy reconstruction in disappearance experiments 

      Ankowski, Artur M.; Benhar, Omar; Coloma, Pilar; Huber, Patrick; Jen, C. M.; Mariani, Camillo; Meloni, D.; Vagnoni, E. (Amer Physical Soc, 2015-10-22)
      To be able to achieve their physics goals, future neutrino-oscillation experiments will need to reconstruct the neutrino energy with very high accuracy. In this work, we analyze how the energy reconstruction may be affected ...
    • Comparison of vibrational and electronic contributions to van der Waals interactions 

      Park, K.; Pederson, M. R.; Liu, A. Y. (American Physical Society, 2006-05)
      The van der Waals interaction can be caused by either ionic vibrations or instantaneous electronic motion relative to the atomic center. In this study, the vibrational contribution to the van der Waals interaction is ...
    • Competition between multiple totally asymmetric simple exclusion processes for a finite pool of resources 

      Cook, L. J.; Zia, R. K. P.; Schmittmann, B. (American Physical Society, 2009-09)
      Using Monte Carlo simulations and a domain-wall theory, we discuss the effect of coupling several totally asymmetric simple exclusion processes (TASEPs) to a finite reservoir of particles. This simple model mimics directed ...
    • Complete fourier direct magnetic resonance imaging (CFD-MRI) for diffusion MRI 

      Ozcan, Alpay (2013)
      The foundation for an accurate and unifying Fourier-based theory of diffusion weighted magnetic resonance imaging (DW MRI) is constructed by carefully re-examining the first principles of DW MRI signal formation and deriving ...
    • Complexity, fractals, disease time, and cancer 

      Spillman, William B.; Robertson, John L.; Huckle, William R.; Govindan, B. S.; Meissner, Kenith E. (American Physical Society, 2004-12)
      Despite many years of research, a method to precisely and quantitatively determine cancer disease state remains elusive. Current practice for characterizing solid tumors involves the use of varying systems of tumor grading ...

      Ruscio, J. Z.; Onufriev, Alexey V. (CELL PRESS, 2006-12-01)
      Molecular dynamics simulations of the nucleosome core particle and its isolated DNA free in solution are reported. The simulations are based on the implicit solvent methodology and provide insights into the nature of ...

      Bowen, Samuel P. (American Physical Society, 1978-10)
      A new theoretical treatment of the Anderson model of transition-metal or rare-earth impurities in a simple metal is presented. This study treats the impurity Coulomb correlation exactly and the host impurity coupling to ...
