  • Argiroffi, C.; Maggio, A.; Montmerle, T.; Alecian, E.; Audard, M.; Bouvier, J.; Damiani, F.; Donati, J.-F.; Gregory, S. G.; Güdel, M.; Hussain, G. A. J.; Kastner, J. H.; Sacco, G. G.; Huenemoerder, David P. (IOP Publishing, 2012-05)
    We report initial results from a quasi-simultaneous X-ray/optical observing campaign targeting V4046 Sgr, a close, synchronous-rotating classical T Tauri star (CTTS) binary in which both components are actively accreting. ...
  • Arachchi, Harindra M.; Green, Lisa M.; Zody, Michael C.; Lennon, Niall; Gnerre, Sante; Berlin, Aaron M.; Nusbaum, Chad; Garber, Manuel (BioMed Central Ltd., 2009-06)
    The most recent release of the finished human genome contains 260 euchromatic gaps (excluding chromosome Y). Recent work has helped explain a large number of these unresolved regions as 'structural' in nature. Another class ...
  • Suresh Kumar, Swarun; Gollakota, Shyamnath; Katabi, Dina (Association for Computing Machinery, 2012-08)
    This paper presents Carcel, a cloud-assisted system for autonomous driving. Carcel enables the cloud to have access to sensor data from autonomous vehicles as well as the roadside infrastructure. The cloud assists autonomous ...
  • Guinard, Dominique; Floerkemeir, Christian; Sarma, Sanjay Emani (Association for Computing Machinery, 2011-06)
    While of increasing importance for the real-time enterprise, deployments of Internet of Things infrastructures such as RFID remain complex and expensive. In this paper, we illustrate these challenges by studying the ...
  • Garimella, Sarvesh; Huang, Y.-W.; Seewald, J. S.; Cziczo, Daniel James (Copernicus GmbH on behalf of the European Geosciences Union, 2014-06)
    This study examines the interaction of clay mineral particles and water vapor for determining the conditions required for cloud droplet formation. Droplet formation conditions are investigated for two common clay minerals, ...
  • Burgasser, Adam; Simcoe, Robert A.; Bochanski, John J.; Saumon, Didier; Mamajek, Eric E.; Cushing, Michael C.; Marley, Mark S.; McMurtry, Craig; Pipher, Judith L.; Forrest, William J. (IOP Publishing, 2010-11)
    Condensate clouds are a salient feature of L dwarf atmospheres, but have been assumed to play little role in shaping the spectra of the coldest T-type brown dwarfs. Here we report evidence of condensate opacity in the ...

    Pham, Hubert; Mazzola Paluska, Justin; Miller, Robert C.; Ward, Steve (Association for Computing Machinery, 2011-10)
    Even as users rely more on the web for their computing needs, they continue to depend on a desktop-like area for quick access to in-use resources. The traditional desktop is file-centric and prone to clutter, making it ...
  • Hou, Jennifer Y.; Grant, Robert A.; Sauer, Robert T.; Roman-Hernandez, Giselle; Baker, Tania; Hou, Jennifer Y.; Grant, Robert A.; Sauer, Robert T. (Elsevier, 2011-07)
    The ClpS adaptor delivers N-end rule substrates to ClpAP, an energy-dependent AAA+ protease, for degradation. How ClpS binds specific N-end residues is known in atomic detail and clarified here, but the delivery mechanism ...
  • Sauer, Robert T.; Baker, Tania (Elsevier, 2011-06)
    ClpXP is a AAA+ protease that uses the energy of ATP binding and hydrolysis to perform mechanical work during targeted protein degradation within cells. ClpXP consists of hexamers of a AAA+ ATPase (ClpX) and a tetradecameric ...
  • Borodin, Alexei (Independent University of Moscow, 2014-03)
    We prove a CLT for spectra of submatrices of real symmetric and Hermitian Wigner matrices. We show that if in the standard normalization the fourth moment of the off-diagonal entries is GOE/GUE-like then the limiting ...
  • Bufetov, A.; Borodin, Alexei (Springer-Verlag, 2013-04)
    We study the asymptotics of traces of (noncommutative) monomials formed by the images of certain elements of the universal enveloping algebra of the infinite-dimensional unitary group in its Plancherel representations. We ...
  • Pham, Hubert; Paluska, Justin Mazzola; Miller, Robert C.; Ward, Stephen A. (Association for Computing Machinery (ACM), 2012-10)
    On the desktop, users are accustomed to having visible handles to objects that they want to organize, share, or manipulate. Web applications today feature many classes of such objects, like flight itineraries, products ...
  • Martini, Paul; Miller, Eric D.; Brodwin, M.; Stanford, S. A.; Gonzalez, Anthony H.; Bautz, Marshall W.; Hickox, R. C.; Stern, D.; Eisenhardt, P. R.; Galametz, A.; Norman, D.; Jannuzi, B. T.; Dey, A.; Murray, S.; Jones, C.; Brown, M. J. I. (Institute of Physics/American Astronomical Society, 2013-05)
    The fraction of cluster galaxies that host luminous active galactic nuclei (AGNs) is an important probe of AGN fueling processes, the cold interstellar medium at the centers of galaxies, and how tightly black holes and ...
  • Chen, Jerry L.; Villa, Katherine Leigh; Cha, Jae Won; So, Peter T. C.; Kubota, Yoshiyuki; Nedivi, Elly; Chen, Jerry L. (Elsevier B.V., 2012-04)
    A key feature of the mammalian brain is its capacity to adapt in response to experience, in part by remodeling of synaptic connections between neurons. Excitatory synapse rearrangements have been monitored in vivo by ...
  • Chan, Maria K.; Reed, J.; Donadio, D.; Mueller, Timothy K.; Meng, Y. S.; Galli, G.; Ceder, Gerbrand (American Physical Society, 2010-05)
    We investigate the parametrization and optimization of thermal conductivity in silicon-germanium alloy nanowires by the cluster-expansion technique. Si1−xGex nanowires are of interest for thermoelectric applications and ...
  • Syed, Zeeshan; Guttag, John V.; Stultz, Collin M. (Springer, 2007-03)
    This paper describes novel fully automated techniques for analyzing large amounts of cardiovascular data. In contrast to traditional medical expert systems our techniques incorporate no a priori knowledge about disease ...
  • Jiang, Shan; Ferreira, Joseph, Jr.; Gonzalez, Marta C.; Ferreira Jr, Joseph (Springer-Verlag, 2012-04)
    Data mining and statistical learning techniques are powerful analysis tools yet to be incorporated in the domain of urban studies and transportation research. In this work, we analyze an activity-based travel survey conducted ...
  • Egedal-Pedersen, Jan; Le, A.; Katz, N.; Chen, L. -J.; Lefebvre, B.; Daughton, W.; Fazakerley, A. (American Geophysical Union (AGU), 2010-03)
    [1] So-called bidirectional electron beams have been observed by a number of spacecraft missions mainly in the inflow of reconnection regions. Here we show that these beam-like features in the electron distribution function ...

(National Academy of Sciences (U.S.), 2012-05)
    The large chromosomal deletions frequently observed in cancer genomes are often thought to arise as a “two-hit” mechanism in the process of tumor-suppressor gene (TSG) inactivation. Using a murine model system of hepatocellular ...
