    • About individual differences in vision 

      Grzeczkowski, L.; Clarke, A. M.; Francis, G.; Mast, F. W.; Herzog, M. H. (Pergamon Press, 2017)
      In cognition, audition, and somatosensation, performance strongly correlates between different para-digms, which suggests the existence of common factors. In contrast, visual performance in seeminglyvery similar tasks, ...
    • About the Wigner distribution of a graded index medium and the fractional fourier transform operation 

      Özaktaş, Haldun M.; Mendlovic, D.; Lohmann, A. W. (SPIE, 1993-08)
      Upon propagation through quadratic graded index media, the Wigner distribution of the wavefunction of light rotates uniformly. As a consequence, a definition of fractional Fourier transforms based on rotating the functions ...

      The realization of 2D ultrathin crystals with a ferromagnetic ground state that is sustainable at room temperature has been a real challenge now. By combining ab initio density functional theory with Monte Carlo simulations, ...
    • Absence of metallicity in Cs-GaAs(110): A Hubbard-model study 

      Gedik, Z.; Çıracı, Salim; Batra, I. P. (American Physical Society, 1993)
      Using an approximate solution of the Hubbard-model Hamiltonian, we are able to establish that the Cs-GaAs(110) system becomes a Mott insulator at submonolayer Cs coverages. We also provide a consistent interpretation of ...
    • Absence of phase transitions in one-dimensional antiferromagnetic models with long-range interactions 

      Kerimov, A. (Kluwer Academic Publishers-Plenum PublishersSpringer New York LLC, 1993)
      The absence of phase transitions in a one-dimensional model with long-range antiferromagnetic potential is established at low temperatures when the ground states have a rational density. A description of the set of all ...
    • Absolute continuity for operator valued completely positive maps on C *-algebras 

      Gheondea, A.; Kavruk, A. Ş. (2009)
      Motivated by applicability to quantum operations, quantum information, and quantum probability, we investigate the notion of absolute continuity for operator valued completely positive maps on C* -algebras, previously ...
    • Absolute temperature monitoring using RF radiometry in the MRI scanner 

      El-Sharkawy, A.-M. M.; Sotiriadis, P. P.; Bottomley, P. A.; Atalar, Ergin (Institute of Electrical and Electronics Engineers, 2006)
      Temperature detection using microwave radiometry has proven value for noninvasively measuring the absolute temperature of tissues inside the body. However, current clinical radiometers operate in the gigahertz range, which ...
    • Absorbing boundary condition for the Schrödinger equation

    • Absorption enhancement in InGaN-based photonic crystal-implemented solar cells 

      Gundogdu, T. F.; Gokkavas, M.; Özbay, Ekmel (SPIE, 2012-07-26)
      We investigate the absorption characteristics of InGaN solar cells with high indium (0.8) content and a one-dimensional periodic nano-scale pattern (implemented) in the InGaN layer theoretically. The short-circuit current ...
    • Absorption enhancement of molecules in the weak plasmon-exciton coupling regime 

      Balci, S.; Karademir, E.; Kocabas, C.; Aydınlı, Atilla (Optical Society of American (OSA), 2014)
      We report on the experimental and theoretical investigations of enhancing the optical absorption of organic molecules in the weak plasmon-exciton coupling regime. A metal-organic hybrid structure consisting of dye molecules ...
    • Abstract metaprolog engine 

      Cicekli, I. (Elsevier, 1998)
      A compiler-based meta-level system for MetaProlog language is presented. Since MetaProlog is a meta-level extension of Prolog, the Warren Abstract Machine (WAM) is extended to get an efficient implementation of meta-level ...
    • Abstract «idols» from Troy 

      Zimmermann, T. (Roemisch-Germanisches Zentralmuseum, 2004)
      Five abstract Early Bronze Age idols from the Schliemann Collection of Trojan objects in the Römisch-Germanische Zentralmuseum are presented. Apart from their formal classification possible alternative functions of certain ...
    • AC electrowetting modulation of low-volatile liquids probed by XPS: dipolar vs ionic screening 

      Aydoğan-Göktürk, Pınar; Ülgüt, Burak; Süzer, Şefik (American Chemical Society, 2019)
      X-ray photoelectron spectroscopic (XPS) data have been recorded for a low-molecular-weight poly(ethylene glycol) microliter-sized sessile liquid drops sitting on a dielectric covered planar electrode while imposing a ±6 V ...
    • AC-driven, color-and brightness-tunable organic light-emitting diodes constructed from an electron only device
