    • Dissipation in a finite-size bath 

      Carcaterra, A.; Akay, A. (American Physical Society, 2011-07-18)
      We investigate the interaction of a particle with a finite-size bath represented by a set of independent linear oscillators with frequencies that fall within a finite bandwidth. We discover that when the oscillators have ...
    • Effects of different lighting arrangements on space perception 

      Manav, B.; Yener, C. (Taylor & Francis, 1999)
      The idea to improve the quality of lighting design in interior spaces has gained importance in the last years. This experimental study concentrateson the quality of lighting and the relation between lighting arrangements ...
    • Effects of different lighting arrangements on space perception 

      Yücetaş, Banu (Bilkent University, 1997)
      The importance given to the quality of lighting design has increased in recent years. This makes lighting design more an art than an engineering problem and it is closely related to the way a space is perceived. It is ...
    • Low drive field amplitude for improved image resolution in magnetic particle imaging 

      Croft, L. R.; Goodwill, P. W.; Konkle, J. J.; Arami, H.; Price, D. A.; Li, A. X.; Saritas, E. U.; Conolly, S. M. (Wiley-Blackwell Publishing, Inc., 2016)
      Purpose: Magnetic particle imaging (MPI) is a new imaging technology that directly detects superparamagnetic iron oxide nanoparticles. The technique has potential medical applications in angiography, cell tracking, and ...
    • Probing viscosity via relaxation in magnetic particle imaging 

      Ütkür, Mustafa (Bilkent University, 2017-01)
      Magnetic Particle Imaging (MPI) is a high-contrast imaging modality with applications such as angiography, stem cell tracking, and cancer imaging. In recent years, MPI was shown to be a potential functional imaging modality ...
    • Quantum efficiency enhancement in film by making nanoparticles of polyfluorene 

      Huyal, I. O.; Ozel, T.; Tuncel, D.; Demir, H. V. (Optical Society of America, 2008)
      We report on conjugated polymer nanoparticles of polyfluorene that were formed to exhibit higher fluorescence quantum efficiency in film (68%) and reduce undesired emission peak wavelength shifts in film (by 20 nm), compared ...
    • Relaxation and nonoccurrence of the Lavrentiev phenomenon for nonconvex problems 

      Hüsseinov, F. (Springer, 2013)
      The paper studies a relaxation of the basic multidimensional variational problem, when the class of admissible functions is endowed with the Lipschitz convergence introduced by Morrey. It is shown that in this setup, the ...
    • Relaxation-based viscosity mapping for magnetic particle imaging 

      Utkur, M.; Muslu, Y.; Saritas, E. U. (Institute of Physics Publishing, 2017)
      Magnetic particle imaging (MPI) has been shown to provide remarkable contrast for imaging applications such as angiography, stem cell tracking, and cancer imaging. Recently, there is growing interest in the functional ...
