  • Li, Bo; Ernst, Darin R. (American Physical Society, 2011-05)
    The gyrokinetic linearized exact Fokker-Planck collision operator is obtained in a form suitable for plasma gyrokinetic equations, for arbitrary mass ratio. The linearized Fokker-Planck operator includes both the test-particle ...
  • Durham, William M.; Climent, Eric; Stocker, Roman (American Physical Society, 2011-06)
    We show that gyrotactic motility within a steady vortical flow leads to tightly clustered aggregations of microorganisms. Two dimensionless numbers, characterizing the relative swimming speed and stability against overturning ...
  • Wang, Zhiyu; Wang, Zheng; Zhang, Bin; Huangfu, Jiangtao; Joannopoulos, John D.; Soljacic, Marin; Ran, Lixin (National Academy of Sciences (U.S.), 2012-07)
    Electromagnetic materials lacking local time-reversal symmetry, such as gyrotropic materials, are of keen interest and importance both scientifically and technologically. Scientifically, topologically nontrivial phenomena, ...
  • Surface, Lauren E.; Fields, Paul A.; Subramanian, Vidya; Behmer, Russell; Udeshi, Namrata; Peach, Sally E.; Carr, Steven A.; Jaffe, Jacob D.; Boyer, Laurie; Surface, Lauren E.; Fields, Paul A. (Elsevier, 2016-01)
    Histone variant H2A.Z occupies the promoters of active and poised, bivalent genes in embryonic stem cells (ESCs) to regulate developmental programs, yet how it contributes to these contrasting states is poorly understood. ...
  • Subramanian, Vidya; Mazumder, Aprotim; Fields, Paul A.; Torrey, Lillian; Levine, Stuart S.; Bathe, Mark; Surface, Lauren Elizabeth; Alwan, Allison M.; Thai, Kevin Kinh; Boyer, Laurie; Butty, Vincent (Public Library of Science, 2013-08)
    The histone H2A variant H2A.Z is essential for embryonic development and for proper control of developmental gene expression programs in embryonic stem cells (ESCs). Divergent regions of amino acid sequence of H2A.Z likely ...
  • Subramanian, Vidya; Fields, Paul A.; Boyer, Laurie (Faculty of 1000, Ltd., 2015-01)
    The replacement of nucleosomal H2A with the histone variant H2A.Z is critical for regulating DNA-mediated processes across eukaryotes and for early development of multicellular organisms. How this variant performs these ...
  • Ku, Manching; Jaffe, Jacob D.; Koche, Richard Patrick; Rheinbay, Esther; Endoh, Mitsuhiro; Koseki, Haruhiko; Carr, Steven A.; Bernstein, Bradley E. (Biomed Central Ltd., 2012-10)
    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 obscure. Results: ...

    An H5N1 highly pathogenic avian influenza virus was isolated from conjunctiva of a whooper swan with neurological signs, which was captured during the latest H5N1 HPAI outbreak in Japan. The conjunctival swab contained a ...
  • Ren, Jing; Qin, Chang; Hu, Fei; Tan, Jie; Qiu, Li; Zhao, Shengli; Feng, Guoping; Luo, Minmin (Elsevier, 2011-02)
    Acetylcholine is an important neurotransmitter, and the habenulo-interpeduncular projection is a major cholinergic pathway in the brain. To study the physiological properties of cholinergic transmission in the interpeduncular ...
  • 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 ...
  • Wang, Chong; Todadri, Senthil (American Physical Society, 2016-02)
    We synthesize and partly review recent developments relating the physics of the half-filled Landau level in two dimensions to correlated surface states of topological insulators in three dimensions. The latter are in turn ...
  • Assef, R. J.; Eisenhardt, P. R. M.; Stern, D.; Tsai, C.-W.; Wu, J.; Wylezalek, D.; Blain, A. W.; Bridge, C. R.; Donoso, E.; Griffith, R. L.; Jarrett, T. H.; Gonzales, Alexandria (IOP Publishing, 2015-04)
    The Wide-field Infrared Survey Explorer mission has unveiled a rare population of high-redshift (z = 1–4.6), dusty, hyper-luminous galaxies, with infrared luminosities L[subscript IR] > 10[superscript 13] L[subscript ⊙], ...
  • 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.; Finkel’stein, 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 ...
