    • Accelerated phase-cycled SSFP imaging with compressed sensing 

      Çukur, T. (Institute of Electrical and Electronics Engineers Inc., 2015)
      Balanced steady-state free precession (SSFP) imaging suffers from irrecoverable signal losses, known as banding artifacts, in regions of large B0 field inhomogeneity. A common solution is to acquire multiple phase-cycled ...

    • Density profile of a Bose-Einstein condensate inside a pancake-shaped trap: Observational consequences of the dimensional cross-over in the scattering properties 

      Tanatar, Bilal; Minguzzi, A.; Vignolo, P.; Tosi, M. P. (Elsevier Science B.V., 2002)
      It is theoretically well known that two-dimensionality of the scattering events in a Bose-Einstein condensate introduces a logarithmic dependence on density in the coupling constant entering a mean-field theory of the ...

    • Detection of a long non-coding RNA (CCAT1) in living cells and human adenocarcinoma of colon tissues using FIT–PNA molecular beacons 

      Kam, Y.; Rubinstein, A.; Naik, S.; Djavsarov, I.; Halle, D.; Ariel, I.; Gure, A. O.; Stojadinovic, A.; Pan, H. G.; Tsivin, V.; Nissan, A.; Yavin, E. (Elsevier Ireland Ltd., 2014-09-28)
      Although the function and mechanism of action of long non-coding RNAs (lncRNA) is still not completely known, studies have shown their potential role in the control of gene expression and regulation, in cellular proliferation ...

    • MaterialVis: material visualization tool using direct volume and surface rendering techniques 

      Okuyan, E.; Güdükbay, Uğur; Bulutay, C.; Heinig, Karl-Heinz (Elsevier Inc., 2014)
      Visualization of the materials is an indispensable part of their structural analysis. We developed a visualization tool for amorphous as well as crystalline structures, called MaterialVis. Unlike the existing tools, ...

    • Microscopic characterization of peptide nanostructures 

      Mammadov, Rashad; Tekinay, Ayse B.; Dana, Aykutlu; Güler, Mustafa O. (Elsevier, 2012)
      Peptide-based nanomaterials have been utilized for various applications from regenerative medicine to electronics since they provide several advantages including easy synthesis methods, numerous routes for functionalization ...

    • Power dissipation analysis in tapping-mode atomic force microscopy 

      Balantekin, M.; Atalar, Abdullah (American Physical Society, 2003)
      In a tapping-mode atomic force microscope, a power is dissipated in the sample during the imaging process. While the vibrating tip taps on the sample surface, some part of its energy is coupled to the sample. Too much ...

    • Profile-encoding reconstruction for multiple-acquisition balanced steady-state free precession imaging 

      Ilicak, Efe; Senel, Lutfi Kerem; Biyik, Erdem; Çukur, Tolga (John Wiley and Sons Inc., 2017)
      Purpose: The scan-efficiency in multiple-acquisition balanced steady-state free precession imaging can be maintained by accelerating and reconstructing each phase-cycled acquisition individually, but this strategy ignores ...

    • Resonant harmonic response in tapping-mode atomic force microscopy 

      Sahin, O.; Quate, C. F.; Solgaard, O.; Atalar, Abdullah (American Physical Society, 2004)
      Higher harmonics in tapping-mode atomic force microscopy offers the potential for imaging and sensing material properties at the nanoscale. The signal level at a given harmonic of the fundamental mode can be enhanced if ...

    • Roadmap on wavefront shaping and deep imaging in complex media 

      Gigan, Sylvain; Katz, Ori; De Aguiar, Hilton B.; Andresen, Esben Ravn; Aubry, Alexandre; Bertolotti, Jacopo; Bossy, Emmanuel; Bouchet, Dorian; Brake, Joshua; Brasselet, Sophie; Bromberg, Yaron; Cao, Hui; Chaigne, Thomas; Cheng, Zhongtao; Choi, Wonshik; Čižmár, Tomáš; Cui, Meng; Curtis, Vincent R.; Defienne, Hugo; Hofer, Matthias; Horisaki, Ryoichi; Horstmeyer, Roarke; Ji, Na; LaViolette, Aaron K.; Mertz, Jerome; Moser, Christophe; Mosk, Allard P; Pégard, Nicolas C; Piestun, Rafael; Popoff, Sebastien; Phillips, David B.; Psaltis, Demetri; Rahmani, Babak; Rigneault, Hervé; Rotter, Stefan; Tian, Lei; Vellekoop, Ivo M.; Waller, Laura; Wang, Lihong; Weber, Timothy; Xiao, Sheng; Xu, Chris; Yamilov, Alexey; Yang, Changhuei; Yılmaz, Hasan (Institute of Physics, 2022-10)
      The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow us to understand and control light propagation in a complex medium, such as ...

    • Room temperature scanning Hall probe microscopy using GaAs/AlGaAs and Bi micro-hall probes 

      Sandhu, A.; Masuda, H.; Oral, A.; Yamada, A.; Konagai, M. (Elsevier Science B.V., 2002)
