  • Iannucci, Peter A.; Fleming, Kermin Elliott; Perry, Jonathan; Balakrishnan, Hari; Shah, Devavrat (Association for Computing Machinery (ACM), 2012-10)
    Spinal codes are a recently proposed capacity-achieving rateless code. While hardware encoding of spinal codes is straightforward, the design of an efficient, high-speed hardware decoder poses significant challenges. We ...
  • Chakrabarty, Deepto; Tomsick, John A.; Grefenstette, Brian W.; Psaltis, Dimitrios; Bachetti, Matteo; Barret, Didier; Boggs, Steven E.; Christensen, Finn E.; Craig, William W.; Fürst, Felix; Hailey, Charles J.; Harrison, Fiona A.; Kaspi, Victoria M.; Miller, Jon M.; Nowak, Michael A.; Rana, Vikram; Stern, Daniel; Wik, Daniel R.; Wilms, Jörn; Zhang, William W.; Nowak, Michael A (Institute of Physics/American Astronomical Society, 2014-12)
    The low-mass X-ray binary (LMXB) Cen X-4 is the brightest and closest (<1.2 kpc) quiescent neutron star transient. Previous 0.5-10 keV X-ray observations of Cen X-4 in quiescence identified two spectral components: soft ...

    We present results from Suzaku and Swift observations of the nearby radio galaxy 3C 33, and investigate the nature of absorption, reflection, and jet production in this source. We model the 0.5-100 keV nuclear continuum ...
  • Wang, Zhiyu; Luo, Yu; Jiang, Tao; Wang, Zheng; Huangfu, Jiangtao; Ran, Lixin (American Physical Society, 2011-01)
    We experimentally demonstrate a microwave far-field image reconstruction modality with the transverse resolution exceeding the diffraction limit by using a single layer of highly nonlinear metamaterial. The harmonic fields ...
  • Gentine, P.; Polcher, J.; Entekhabi, Dara (American Geophysical Union, 2011-05)
    [1] The response of a soil-vegetation-atmosphere continuum model to incoming radiation forcing is investigated in order to gain insights into the coupling of soil and atmospheric boundary layer (ABL) states and fluxes. The ...
  • Robinson, Luke N.; Artpradit, Charlermchai; Raman, Rahul; Shriver, Zachary H.; Ruchirawat, Mathuros; Sasisekharan, Ram (Wiley Blackwell, 2012-04)
    Glycans, or complex carbohydrates, are a ubiquitous class of biological molecule which impinge on a variety of physiological processes ranging from signal transduction to tissue development and microbial pathogenesis. In ...
  • Finney-Manchester, Shawn Pete; Maheshri, Narendra (Oxford University Press, 2013-03)
    A major hurdle to evolutionary engineering approaches for multigenic phenotypes is the ability to simultaneously modify multiple genes rapidly and selectively. Here, we describe a method for in vivo-targeted mutagenesis ...
  • Ranganath, Sudhir H.; Levy, Oren; Inamdar, Maneesha S.; Karp, Jeffrey Michael; Ranganath, Sudhir H. (Elsevier B.V., 2012-03)
    The broad repertoire of secreted trophic and immunomodulatory cytokines produced by mesenchymal stem cells (MSCs), generally referred to as the MSC secretome, has considerable potential for the treatment of cardiovascular ...
  • Winn, Joshua Nathan; Johnson, John Asher; Howard, Andrew W.; Marcy, Geoffrey W.; Bakos, Gaspar A.; Hartman, Joel; Torres, Guillermo; Albrecht, Simon H.; Narita, Norio (Institute of Physics, 2010-07)
    We present new radial velocity (RV) measurements of HAT-P-13, a star with two previously known companions: a transiting giant planet "b" with an orbital period of 3 days and a more massive object "c" on a 1.2 yr, highly ...

    We report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V = 10.419 dwarf star GSC 0208-00722. The planet has a period P = 2.810595 [plus-minus] 0.000005 days, transit epoch T[subscript c] = 2455456.46561 ...
  • Hartman, J. D.; Torres, G.; Johnson, J. A.; Howard, A. W.; Marcy, G. W.; Latham, D. W.; Bieryla, A.; Buchhave, L. A.; Bhatti, W.; Csubry, Z.; Penev, K.; de Val-Borro, M.; Noyes, R. W.; Fischer, D. A.; Esquerdo, G. A.; Everett, M.; Zhou, G.; Bayliss, D.; Shporer, A.; Fulton, B. J.; Falco, E.; Papp, I.; Sanchis Ojeda, Roberto; Bakos, G. A.; Kovacs, G.; Beky, B.; Szklenar, T.; Lazar, J.; Sari, P. (IOP Publishing, 2014-04)
    We report the discovery by the HATNet survey of three new transiting extrasolar planets orbiting moderately bright (V = 13.2, 12.8, and 11.9) stars. The planets have orbital periods of 4.3012, 3.1290, and 4.4631 days, ...
  • Winn, Joshua Nathan; Johnson, John Asher; Albrecht, Simon H.; Howard, Andrew W.; Marcy, Geoffrey W.; Crossfield, Ian J.; Holman, Matthew J. (American Astronomical Society, 2009-10)
    We show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86° with respect to its parent star's equatorial plane, and a strong possibility of retrograde motion. We also report evidence ...
  • Zhang, Rong; Delworth, Thomas L.; Sutton, Rowan; Hodson, Daniel L. R.; Dixon, Keith W.; Held, Isaac M.; Kushnir, Yochanan; Ming, Yi; Msadek, Rym; Robson, Jon; Rosati, Anthony J.; Ting, MingFang; Vecchi, Gabriel A.; Marshall, John C. (American Meteorological Society, 2013-04)
    Identifying the prime drivers of the twentieth-century multidecadal variability in the Atlantic Ocean is crucial for predicting how the Atlantic will evolve in the coming decades and the resulting broad impacts on weather ...
  • Adams, Allan; Saremi, Omid; Roberts, Daniel Adam (American Physical Society, 2015-02)
    We study the Hawking-Page transition in a holographic model of field theories with momentum dissipation. We find that the deconfinement temperature strictly decreases as momentum dissipation is increased. For sufficiently ...
  • Porfyriadis, Achilleas P. (American Physical Society, 2009-04)
    The anomaly cancellation method proposed by Wilczek et al. is applied to the general charged rotating black holes in five-dimensional minimal gauged supergravity. Thus Hawking temperature and fluxes are found. The Hawking ...
  • Ishimatsu, Takuto; Leveson, Nancy G.; Thomas, John P.; Katahira, Masafumi; Miyamoto, Yuko; Ujiie, Ryo; Nakao, Haruka; Hoshino, Nobuyuki; Fleming, Cody (American Institute of Aeronautics and Astronautics, 2014-02)
    A new hazard analysis technique, called systems-theoretic process analysis, is capable of identifying potential hazardous design flaws, including software and system design errors and unsafe interactions among multiple ...
  • Cheng, Ing-Haw; Milbradt, Konstantin (Oxford University Press, 2011-12)
    We investigate the trade-off between incentive provision and inefficient rollover freezes for a firm financed with short-term debt. First, debt maturity that is too short-term is inefficient, even with incentive provision. ...
