  • Konidaris, George D.; Kaelbling, Leslie P.; Lozano-Perez, Tomas (Association for the Advancement of Artificial Intelligence (AAAI), 2014-07)
    We consider the problem of constructing a symbolic description of a continuous, low-level environment for use in planning. We show that symbols that can represent the preconditions and effects of an agent's actions are ...
  • Ye, Peng; Wen, Xiao-Gang (American Physical Society, 2014-01)
    Recently, there is a considerable study on gapped symmetric phases of bosons that do not break any symmetry. Even without symmetry breaking, the bosons can still be in many exotic new states of matter, such as symmetry-protected ...
  • Yuan, Haidong; Zeier, Robert; Khaneja, Navin; Lloyd, Seth (American Physical Society, 2009-04)
    Couplings between quantum systems are frequently less robust and harder to implement than controls on individual systems; thus, constructing quantum gates with minimal interactions is an important problem in quantum ...
  • Lanman, Douglas R.; Wetzstein, Gordon; Raskar, Ramesh; Hirsch, Matthew Waggener (IOP Publishing, 2013-02)
    Near-term commercial multi-view displays currently employ ray-based 3D or 4D light field techniques. Conventional approaches to ray-based display typically include lens arrays or heuristic barrier patterns combined with ...
  • Bliss, Nadya T.; Sun, Zachary; Ni, Karl S.; Snavely, Noah (SPIE, 2010-01)
    This paper proposes a trainable computer vision approach for visual object registration relative to a collection of training images obtained a priori. The algorithm first identifies whether or not the image belongs to the ...
  • Srinivas, Anand; Zussman, Gil; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers / Association for Computing Machinery, 2009-02)
    We study a novel hierarchical wireless networking approach in which some of the nodes are more capable than others. In such networks, the more capable nodes can serve as mobile backbone nodes and provide a backbone over ...
  • Hines, James; Malone, Thomas W.; Goncalves, Paulo; Herman, George; Quimby, John; Murphy-Hoye, Mary; Rice, James Blayney; Patten, James; Ishii, Hiroshi (John Wiley & Sons, Inc., 2010-07)
    Simulation modeling can be valuable in many areas of management science, but it is often costly, time-consuming, and difficult to do. To reduce these problems, system dynamics researchers have previously developed standard ...
  • Zuckerman Sivan, Ezra W. (Annual Reviews, 2012-08)
    I review and integrate recent sociological research that makes progress on three interrelated questions pertaining to social valuation: (a) the degree of social construction relative to objective constraints; (b) the degree ...
  • Wen, Xiao-Gang (American Physical Society, 2015-05)
    It has been shown that the bosonic symmetry-protected-trivial (SPT) phases with pure gauge anomalous boundary can all be realized via nonlinear σ models (NLσMs) of the symmetry group G with various topological terms. Those ...
  • Lin, Dahua; Grimson, Eric; Fisher, John W., III (Neural Information Processing Systems Foundation (NIPS), 2010-12)
    We present a method for constructing dependent Dirichlet processes. The new approach exploits the intrinsic relationship between Dirichlet and Poisson processes in order to create a Markov chain of Dirichlet processes ...
  • Di Sabatino, Silvana; Leo, Laura S.; Cataldo, Rosella; Ratti, Carlo; Britter, Rex E. (American Meteorological Society, 2010-07)
    A morphometric analysis of a southern European city and the derivation of relevant fluid dynamical parameters for use in urban flow and dispersion models are explained in this paper. Calculated parameters are compared with ...
  • Kedlaya, Kiran S. (American Mathematical Society (AMS), 2012-09)
    For any integer n ≥ 2 and any nonnegative integers r, swith r+2s = n, we give an unconditional construction of infinitely many monic irreducible polynomials of degree n with integer coefficients having squarefree discriminant ...
  • Han, Sewoon; Shin, Yoojin; Jeong, Hyo Eun; Jeon, Jessie S.; Huh, Dongeun; Sohn, Lydia L.; Chung, Seok; Kamm, Roger Dale (Nature Publishing Group, 2015-12)
    The construction of well-controllable in vitro models of physiological and pathological vascular endothelium remains a fundamental challenge in tissue engineering and drug development. Here, we present an approach for ...
  • Khandani, Amir Ehsan; Kim, Adlar J.; Lo, Andrew W. (Elsevier B.V., 2010-06)
    We apply machine-learning techniques to construct nonlinear nonparametric forecasting models of consumer credit risk. By combining customer transactions and credit bureau data from January 2005 to April 2009 for a sample ...
  • Meredith, Laura K.; Rao, Deepa; Bosak, Tanja; Klepac-Ceraj, Vanja; Tada, Kendall R.; Hansel, Colleen M.; Ono, Shuhei; Prinn, Ronald G. (Wiley Blackwell, 2014-06)
    Microbe-mediated soil uptake is the largest and most uncertain variable in the budget of atmospheric hydrogen (H[subscript 2]). The diversity and ecophysiological role of soil microorganisms that can consume low atmospheric ...
  • ’t Mannetje, D. J. C. M.; Oh, J. M.; Eral, Huseyin Burak (Springer-Verlag, 2012-09)
    Contact angle hysteresis is an important physical phenomenon. It is omnipresent in nature and also plays a crucial role in various industrial processes. Despite its relevance, there is a lack of consensus on how to incorporate ...
  • Bai, Jing; Adriani, Giulia; Dang, Truong-Minh; Tu, Ting-Yuan; Penny, Hwei-Xian Leong; Wong, Siew-Cheng; Thiery, Jean-Paul; Kamm, Roger Dale (Impact Journals/National Center for Biotechnology Information (U.S.), 2015-07)
    Tumor-associated macrophages (TAMs) can constitute up to 50% of the tumor mass and have strong implications in tumor progression and metastasis. Macrophages are plastic and can polarize to various subtypes that differ in ...
  • Mentzel, Tamar; MacLean, Kenneth; Kastner, Marc (American Chemical Society (ACS), 2011-09)
    Contact effects are a common impediment to electrical measurements throughout the fields of nanoelectronics, organic electronics, and the emerging field of graphene electronics. We demonstrate a novel method of measuring ...
  • Lang, Jeffrey H.; Read, Melissa B.; Martens, R.; Slocum, Alexander H. (Institute of Electrical and Electronics Engineers, 2009-10)
    MEMS-fabricated electrical contacts are commonly used in MEMS relays. These electrical contacts can be as simple as two flat surfaces coming into contact [1]. Modeling their contact force/resistance relationship can be ...
  • Seslen, Tracey; Wheaton, William C. (American Real Estate and Urban Economics Association, 2010-07)
    This study analyzes the impact of contemporaneous loan stress on the termination of loans in the commercial mortgage-backed securities pool from 1992 to 2004 using a novel measure, based on changes in net operating incomes ...
