  • Jordan, Andres; Espinoza, Nestor; Rabus, Markus; Eyheramendy, Susana; Sing, David K.; Desert, Jean-Michel; Bakos, Gaspar A.; Fortney, Jonathan J.; Lopez-Morales, Mercedes; Maxted, Pierre F. L.; Triaud, Amaury; Szentgyorgyi, Andrew (Institute of Physics/American Astronomical Society, 2013-12)
    We present a ground-based optical transmission spectrum of the inflated sub-Jupiter-mass planet WASP-6b. The spectrum was measured in 20 spectral channels from 480 nm to 860 nm using a series of 91 spectra over a complete ...
  • Guenther, Matthew G.; Young, Richard A.; Young, Richard A. (Elsevier, 2012-05)
    Growing mouse pluripotent stem cells in defined media with signaling inhibitors establishes a naive ground state different from that of cells grown in serum. Recently in Cell, Marks et al. (2012) reported differences in ...
  • Roy, Brandon C.; Vosoughi, Soroush; Roy, Deb K. (International Speech Communication Association, 2014-09)
    Natural language is rich and varied, but also highly structured. The rules of grammar are a primary source of linguistic regularity, but there are many other factors that govern patterns of language use. Language models ...
  • Tellex, Stefanie A.; Roy, Deb K. (Association for Computing Machinery, 2009-11)
    Spatial language video retrieval is an important real-world problem that forms a test bed for evaluating semantic structures for natural language descriptions of motion on naturalistic data. Video search by natural language ...
  • Pinto, Federico; Whittle, Andrew (American Society of Civil Engineers (ASCE), 2014-04)
    This paper presents simplified closed-form analytical solutions that can be used to interpret and predict ground movements caused by shallow tunneling in soft ground conditions. These solutions offer a more comprehensive ...
  • McDaniel, Matt W.; Nishihata, Takayuki; Brooks, Christopher A.; Iagnemma, Karl (Institute of Electrical and Electronics Engineers, 2010-05)
    To operate autonomously in forested environments, unmanned ground vehicles (UGVs) must be able to identify the load-bearing surface of the terrain (i.e. the ground). This paper presents a novel two-stage approach for ...
  • Teller, Seth; Huang, Albert S.; Koch, Olivier A.; Walter, Matthew R. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    Precise calibration of camera intrinsic and extrinsic parameters, while often useful, is difficult to obtain during field operation and presents scaling issues for multi-robot systems. We demonstrate a vision-based approach ...
  • Cohn, Henry; Kumar, Abhinav; Schurmann, Achill (American Physical Society, 2009-12)
    We study dimensional trends in ground states for soft-matter systems. Specifically, using a high-dimensional version of Parrinello-Rahman dynamics, we investigate the behavior of the Gaussian core model in up to eight ...
  • Hu, Qing; Reno, John L.; Chan, Chun Wang Ivan (American Institute of Physics (AIP), 2012-10)
    A terahertz quantum cascade laser (THz QCL) architecture is presented in which only the ground state subbands of each quantum well are involved in the transport and lasing transition. Compared to state-of-the art THz QCLs ...
  • Grosse, Roger Baker; Johnson, Micah K.; Adelson, Edward H.; Freeman, William T. (Institute of Electrical and Electronics Engineers, 2010-05)
    The intrinsic image decomposition aims to retrieve “intrinsic” properties of an image, such as shading and reflectance. To make it possible to quantitatively compare different approaches to this problem in realistic settings, ...
  • Mukherjee, Abhijit; Saha, Dipankar; Harvey, Charles F.; Taylor, Richard G.; Ahmed, Kazi Matin; Bhanja, Soumendra N. (Elsevier, 2015-04)
    The Indian Sub-Continent is one of the most densely populated regions of the world, hosting ∼23% of the global population within only ∼3% of the world's land area. It encompasses some of the world's largest fluvial systems ...
  • Como, Giacomo (Institute of Electrical and Electronics Engineers, 2010-08)
    Typical minimum distances and error exponents are analyzed on the 8-PSK Gaussian channel for two capacity-achieving code ensembles with different algebraic structure. It is proved that the typical group code over the cyclic ...
  • Guo, Alan Xinyu (European Mathematical Information Service (EMIS), 2015-01)
    We investigate the minimum distance of the error correcting code formed by the homomorphisms between two finite groups G and H. We prove some general structural results on how the distance behaves with respect to natural ...
  • Chen, Daozheng; Batra, Dhruv; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2013-12)
    Latent variables models have been applied to a number of computer vision problems. However, the complexity of the latent space is typically left as a free design choice. A larger latent space results in a more expressive ...
  • Zhang, Ruixun; Brennan, Thomas J.; Lo, Andrew W. (Public Library of Science, 2014-10)
    Despite many compelling applications in economics, sociobiology, and evolutionary psychology, group selection is still one of the most hotly contested ideas in evolutionary biology. Here we propose a simple evolutionary ...
  • Strang, W. Gilbert (American Mathematical Society, 2011-04)
    A product A=F[subscript 1]...F[subscript N] of invertible block-diagonal matrices will be banded with a banded inverse. We establish this factorization with the number N controlled by the bandwidths w and not by the ...
  • Ribeiro-Soares, J.; Almeida, R. M.; Barros, Eduardo B.; Araujo, Paulo Antonio Trinidade; Jorio, A.; Dresselhaus, Mildred; Cancado, L. G. (American Physical Society, 2014-09)
    Transition metal dichalcogenides (TMDCs) have emerged as a new two-dimensional material's field since the monolayer and few-layer limits show different properties when compared to each other and to their respective bulk ...
  • Ribeiro-Soares, J.; Almeida, R. M.; Jorio, A.; Dresselhaus, Mildred; Cancado, L. G. (American Physical Society, 2015-05)
    Group theory analysis for two-dimensional elemental systems related to phosphorene is presented, including (i) graphene, silicene, germanene, and stanene; (ii) their dependence on the number of layers; and (iii) their two ...
  • Letham, Benjamin; Rudin, Cynthia; Heller, Katherine A. (Springer-Verlag, 2013-07)
    It is easy to find expert knowledge on the Internet on almost any topic, but obtaining a complete overview of a given topic is not always easy: information can be scattered across many sources and must be aggregated to be ...
  • Park, Jun-geun; Charrow, Ben; Curtis, Dorothy; Battat, Jonathan; Minkov, Einat; Hicks, Jamey; Teller, Seth; Ledlie, Jonathan (Association for Computing Machinery, 2010-06)
    Most current methods for 802.11-based indoor localization depend on surveys conducted by experts or skilled technicians. Some recent systems have incorporated surveying by users. Structuring localization systems "organically," ...
