  • Ku, Manching; Rheinbay, Esther; Endoh, Mitsuhiro; Koseki, Haruhiko; Koche, Richard Patrick; Jaffe, Jacob D.; Carr, Steven A.; Bernstein, Bradley E. (BioMed Central Ltd, 2012-10)
    Abstract Background The histone variant H2A.Z has been implicated in nucleosome exchange, transcriptional activation and Polycomb repression. However, the relationships among these seemingly disparate functions remain ...
  • Verdelhan, Adrien Frederic (American Finance Association/Wiley, 2010-01)
    This paper presents a model that reproduces the uncovered interest rate parity puzzle. Investors have preferences with external habits. Countercyclical risk premia and procyclical real interest rates arise endogenously. ...
  • Howe, Mark William; Atallah, Hicham; McCool, Andrew D.; Gibson, Daniel J.; Graybiel, Ann M. (National Academy of Sciences (U.S.), 2011-10)
    Rhythmic brain activity is thought to reflect, and to help organize, spike activity in populations of neurons during on-going behavior. We report that during learning, a major transition occurs in task-related oscillatory ...
  • Song, Gang; Tin, Chung; Giacometti, Emanuela; Poon, Chi-Sang (Frontiers Research Foundation, 2011-05)
    Non-associative learning is a basic neuroadaptive behavior exhibited in almost all animal species and sensory modalities but its functions and mechanisms in the mammalian brain are poorly understood. Previous studies have ...
  • James, Erica C. (Wiley Blackwell, 2011-09)
    In this article, I seek to show how states of insecurity provoked by ongoing social, economic, and political ruptures in Haiti can disorder individual subjectivity and generate the flight of individuals seeking asylum ...
  • Barnes, Connelly; Adams, Andrew; Paris, Sylvain; Ragan-Kelley, Jonathan Millar; Durand, Fredo; Amarasinghe, Saman P. (Association for Computing Machinery (ACM), 2013-06)
    Image processing pipelines combine the challenges of stencil computations and stream programs. They are composed of large graphs of different stencil stages, as well as complex reductions, and stages with global or ...
  • Breznay, Nicholas P.; Michaeli, Karen; Tikhonov, Konstantin S.; Finkelstein, Alexander M.; Tendulkar, Mihir; Kapitulnik, Aharon (American Physical Society, 2012-07)
    We have studied the Hall effect in superconducting tantalum nitride films. We find a large contribution to the Hall conductivity near the superconducting transition, which we can track to temperatures well above T[subscript ...
  • Song, Justin Chien Wen; Levitov, Leonid (American Physical Society, 2013-09)
    Massless Dirac fermions in graphene at charge neutrality form a strongly interacting system in which both charged and neutral (energy) modes play an important role. These modes are essentially decoupled in the absence of ...
  • Michaeli, Karen; Tikhonov, Konstantin S.; Finkel’stein, Alexander M. (American Physical Society, 2012-07)
    Near the superconducting phase transition, fluctuations significantly modify the electronic transport properties. Here we study the fluctuation corrections to the Hall conductivity in disordered films, extending previous ...
  • Lee, Yun Seog; Winkler, Mark Thomas; Siah, Sin Cheng; Brandt, Riley E.; Buonassisi, Tonio (American Institute of Physics (AIP), 2011-05)
    Cuprous oxide (Cu[subscript 2]O) is a promising earth-abundant semiconductor for photovoltaic applications. We report Hall mobilities of polycrystalline Cu[subscript 2]O thin films deposited by reactive dc magnetron ...
  • Cappellaro, Paola; Ticozzi, Francesco; Lucchese, Riccardo; Viola, Lorenza (Institute of Electrical and Electronics Engineers (IEEE), 2012-08)
    We consider finite-dimensional Markovian open quantum systems, and characterize the extent to which time-independent Hamiltonian control may allow to stabilize a target quantum state or subspace and optimize the resulting ...
  • Bookatz, Adam D.; Wocjan, Pawel; Viola, Lorenza (Institute of Physics Publishing and Deutsche Physikalische Gesellschaft, 2014-04)
    We propose dynamical control schemes for Hamiltonian simulation in many-body quantum systems that avoid instantaneous control operations and rely solely on realistic bounded-strength control Hamiltonians. Each simulation ...
  • Campagnano, Gabriele; Zilberberg, Oded; Gornyi, Igor V.; Feldman, Dmitri E.; Potter, Andrew Cole; Gefen, Yuval (American Physical Society, 2012-09)
    We present a study of a Hanbury Brown–Twiss interferometer realized with anyons. Such a device can directly probe entanglement and fractional statistics of initially uncorrelated particles. We calculate Hanbury Brown–Twiss ...
  • Rottigni, A.; Carminati, M.; Ferrari, G.; Vahey, M. D.; Voldman, Joel; Sampietro, M. (SPIE, 2011-05)
    Lab-on-a-chip systems have been attracting a growing attention for the perspective of miniaturization and portability of bio-chemical assays. Here we present a the design and characterization of a miniaturized, USB-powered, ...
  • Jackiw, Roman (Birkhäuser Basel, 2009-03)
    I sketch my experiences with Hans Bethe (1906–2005) as a teacher at Cornell University, beginning with my doctoral studies in 1961 and continuing with my work with him on a quantum-mechanics textbook.
  • Reiling, Jan H.; Clish, Clary; Carette, Jan E.; Varadarajan, Malini; Brummelkamp, Thijn R.; Sabatini, David M. (Proceedings of the National Academy of Sciences (PNAS), 2011-06)
    Tunicamycin (TM) inhibits eukaryotic asparagine-linked glycosylation, protein palmitoylation, ganglioside production, proteoglycan synthesis, 3-hydroxy-3-methylglutaryl coenzyme-A reductase activity, and cell wall biosynthesis ...
  • Ward, Lucas D.; Manolis, Kellis (Oxford University Press, 2011-11)
    The resolution of genome-wide association studies (GWAS) is limited by the linkage disequilibrium (LD) structure of the population being studied. Selecting the most likely causal variants within an LD block is relatively ...
  • Devoto, Florencia; Duflo, Esther; Dupas, Pascaline; Pariente, William; Pons, Vincent (American Economic Association, 2012-11)
    Connecting private dwellings to the water main is expensive and typically cannot be publicly financed. We show that households' willingness to pay for a private connection is high when it can be purchased on credit, not ...
  • Wilczek, Frank (Scientific American, a Division of Nature America/Nature Publishing Group, 2012-05)
    The Higgs gets the headlines, but the electron is really physicists’ favorite particle. The electron theory, developed 120 years ago, is an underappreciated bridge from classical to modern physics.
  • Berger, Emily; Yorukoglu, Deniz; Peng, Jian; Berger, Bonnie (Public Library of Science, 2014-03)
    As the more recent next-generation sequencing (NGS) technologies provide longer read sequences, the use of sequencing datasets for complete haplotype phasing is fast becoming a reality, allowing haplotype reconstruction ...
