  • Chang, Tsung-Hsiang; Yeh, Tom; Miller, Robert C. (Association for Computing Machinery (ACM), 2010-04)
    Testing a GUI's visual behavior typically requires human testers to interact with the GUI and to observe whether the expected results of interaction are presented. This paper presents a new approach to GUI testing using ...
  • Tacchetti, Andrea; Mallapragada, Pavan K.; Santoro, Matteo; Rosasco, Lorenzo (Association for Computing Machinery (ACM), 2013-10)
    We present GURLS, a least squares, modular, easy-to-extend software library for efficient supervised learning. GURLS is targeted to machine learning practitioners, as well as non- specialists. It offers a number state-of-the-art ...
  • Rogers, Arlin B.; Fry, Rebecca C.; Dedon, Peter C.; Tannenbaum, Steven Robert; Schauer, David B.; Essigmann, John M.; Mcfaline, Jose L.; Williams, Michelle V.; Doernte, A. L.; Fiala, Jeannette Louise Allen; Raczynski, Arkadiusz R.; Theve, E. J.; Feng, Yan; Fox, James G.; Lemon, S. M.; Weinman, S. A. (British Society of Gastroenterology, 2009-10)
    Background and aims: Hepatocellular carcinoma (HCC) frequently results from synergism between chemical and infectious liver carcinogens. Worldwide, the highest incidence of HCC is in regions endemic for the foodborne ...
  • Poutahidis, Theofilos; Kleinewietfeld, Markus; Erdman, Susan E. (Frontiers Research Foundation, 2014-04)
    It is recently shown that beneficial environmental microbes stimulate integrated immune and neuroendocrine factors throughout the body, consequently modulating regulatory T-lymphocyte phenotypes, maintaining systemic immune ...
  • Liu, Zheng-Xin; Zhou, Yi; Tu, Hong-Hao; Wen, Xiao-Gang; Ng, Tai-Kai (American Physical Society, 2012-05)
    We study in this paper a series of Gutzwiller projected wave functions for S=1 spin chains obtained from a fermionic mean-field theory for general S>1/2 spin systems [ Liu, Zhou and Ng Phys. Rev. B 81 224417 (2010)] applied ...
  • Ma, Minglin; Thomas, Edwin L.; Rutledge, Gregory C.; Yu, Bin; Li, Baohui; Jin, Qinghua; Ding, Datong; Shi, An-Chang (American Chemical Society, 2010-02)
    The self-assembly of gyroid-forming diblock copolymers confined in cylindrical geometry is studied using a combination of computer simulations and experiments. The simulations, based on a system qualitatively representative ...
  • 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 McKinney; 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, ...
  • 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 ...
  • 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 ...
  • 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: ...
  • 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 ...
