  • Alexandrou, Constantia; Korzec, Tomasz; Koutsou, Giannis; Lorce, C.; Negele, John W.; Pascalutsa, V.; Tsapalis, A.; Vanderhaeghen, M. (American Physical Society, 2009-01)
    We develop techniques to calculate the four Δ electromagnetic form factors using lattice QCD, with particular emphasis on the subdominant electric quadrupole form factor that probes deformation of the Δ. Results are presented ...
  • Schwartz, Galina A.; Tembine, Hamidou; Amin, Saurabh; Sastry, S. Shankar (International Federation of Automatic Control, 2014-08)
    In this paper, we develop a novel mechanism for reducing volatility of residential demand for electricity. We construct a reward-based (rebate) mechanism that provides consumers with incentives to shift their demand to ...
  • Zhang, Juanjuan; Miklos-Thal, Jeanine (American Marketing Association, 2013-02)
    Savvy consumers attribute a product’s market performance to its intrinsic quality as well as the seller’s marketing push. The authors study how sellers should optimize their marketing decisions in response. They find that ...
  • Schilling, Anne; Tingley, Peter (Electronic Journal of Combinatorics, 2012-04)
    It has previously been shown that, at least for non-exceptional Kac-Moody Lie algebras, there is a close connection between Demazure crystals and tensor products of Kirillov-Reshetikhin crystals. In particular, certain ...
  • Cheung, Alvin K.; Thiagarajan, Arvind; Madden, Samuel R. (Association for Computing Machinery (ACM), 2011-11)
    This demo will showcase LifeJoin, a system that collects raw sensor data from phones and laptop computers to generate interesting events. Given the raw sensor data, LifeJoin implements a number of activity recognition ...
  • Reagans, Ray Eugene (Oxford University Press, 2012-12)
    Research documenting the influence of demopraphic diversity on informal social networks is reviewed and critiqued. I focus in particular on research describing the importance of demographic diversity in the development of ...
  • Del Pozzo, W.; Li, Tjonnie G. F.; Agathos, Michalis; Van Den Broeck, Chris; Vitale, Salvatore (American Physical Society, 2013-08)
    Fisher matrix and related studies have suggested that, with second-generation gravitational-wave detectors, it may be possible to infer the equation of state of neutron stars using tidal effects in a binary inspiral. Here, ...
  • Madsen, Miriam A.; el Kaliouby, Rana; Eckhardt, Micah Rye; Goodwin, Matthew; Hoque, Mohammed Ehasanul; Picard, Rosalind W. (Institute of Electrical and Electronics Engineers, 2009-12)
    Social communication in autism is significantly hindered by difficulties processing affective cues in realtime face-to-face interaction. The interactive Social-Emotional Toolkit (iSET) allows its users to record and annotate ...
  • Temkin, Richard J.; Sirigiri, Jagadishwar R.; Joye, Colin D.; Shapiro, Michael (Institute of Electrical and Electronics Engineers, 2009-04)
    The theory, design, and experimental results of a wideband 140-GHz 1-kW pulsed gyro-traveling-wave amplifier (gyro-TWA) are presented. The gyro-TWA operates in the HE [subscript 06] mode of an overmoded quasi-optical ...
  • Liu, Dazhi; Hussey, D.; Gubarev, M. V.; Ramsey, B. D.; Jacobson, D.; Arif, M.; Moncton, David E.; Khaykovich, Boris (American Physical Society, 2013-05)
    An achromatic cold-neutron microscope with magnification 4 is demonstrated. The image-forming optics is composed of nested coaxial mirrors of full figures of revolution, so-called Wolter optics. The spatial resolution, ...
  • Chatterjee, Rohit; Yu, Mingbin; Stein, Aaron; Kwong, Dim-Lee; Kimerling, Lionel C.; Wong, Chee Wei (Optical Society of America, 2010-01)
    We demonstrate an optical hitless bypass switch based on nanomechanical proximity perturbation for high-bitrate transparent networks. Embedded in a single-level π-imbalanced Mach-Zehnder interferometer, the two ...
  • Ohia, Obioma O.; Egedal-Pedersen, Jan; Lukin, V. S.; Daughton, W. (American Physical Society, 2012-09)
    Collisionless magnetic reconnection in high-temperature plasmas has been widely studied through fluid-based models. Here, we present results of fluid simulation implementing new equations of state for guide-field reconnection. ...
  • Liu, Dazhi; Khaykovich, Boris; Gubarev, M. V.; Lee Robertson, J.; Crow, Lowell; Ramsey, Brian D.; Moncton, David E. (Nature Publishing Group, 2013-09)
    Small-angle neutron scattering (SANS) is the most significant neutron technique in terms of impact on science and engineering. However, the basic design of SANS facilities has not changed since the technique’s inception ...
  • Chuang, Isaac L.; Wang, Shannon Xuanyue; Labaziewicz, Jaroslaw; Ge, Yufei; Shewmon, Ruth (American Physical Society, 2010-06)
    We demonstrate quantum control techniques for a single trapped ion in a cryogenic, surface-electrode trap. A narrow optical transition of Sr[superscript +] along with the ground and first excited motional states of the ...
  • Leibrandt, David Ray; Labaziewicz, Jaroslaw; Clark, Robert J.; Chuang, Isaac L.; Edpstein, R. J.; Ospelkaus, C.; Wesenberg, J. H.; Bollinger, J. J.; Leibfried, D.; Wineland, D. J.; Stick, D.; Sterk, J.; Monroe, C.; Pai, C.-S.; Low, Y.; Frahm, R.; Slusher, R. E. (Rinton Press, 2009-11)
    A scalable, multiplexed ion trap for quantum information processing is fabricated and tested. The trap design and fabrication process are optimized for scalability to small trap size and large numbers of interconnected ...
