  • Demaine, Erik D.; Panchekha, Pavel; Wilson, David A.; Yang, Edward Z. (Springer-Verlag Berlin Heidelberg, 2013)
    We consider the problem of merging individual text documents, motivated by the single-file merge algorithms of document-based version control systems. Abstracting away the merging of conflicting edits to an external conflict ...
  • Beyeler, Anna; Felix-Ortiz, Ada Celis; Seo, Changwoo; Leppla, Christopher Albert; Wildes, Craig P.; Tye, Kay (Elsevier, 2013-08)
    The basolateral amygdala (BLA) and ventral hippocampus (vHPC) have both been implicated in mediating anxiety-related behaviors, but the functional contribution of BLA inputs to the vHPC has never been directly investigated. ...
  • Sapsis, Themistoklis; Majda, Andrew J.; Qi, Di (National Academy of Sciences (U.S.), 2014-05)
    Combining large uncertain computational models with big noisy datasets is a formidable problem throughout science and engineering. These are especially difficult issues when real-time state estimation and prediction are ...
  • Maymounkov, Petar Borissov; Toledo, Sivan; Avron, Haim (Society for Industrial and Applied Mathematics, 2010-04)
    Several innovative random-sampling and random-mixing techniques for solving problems in linear algebra have been proposed in the last decade, but they have not yet made a significant impact on numerical linear algebra. We ...
  • Sapsis, Themistoklis Panagiotis; Majda, Andrew J. (Springer US, 2013-07)
    Turbulent dynamical systems are characterized by persistent instabilities which are balanced by nonlinear dynamics that continuously transfer energy to the stable modes. To model this complex statistical equilibrium in the ...
  • Newby, Gregory Arthur; Lindquist, Susan (Elsevier, 2013-06)
    Prions and amyloids are often associated with disease, but related mechanisms provide beneficial functions in nature. Prion-like mechanisms (PriLiMs) are found from bacteria to humans, where they alter the biological and ...
  • Chu, Li-Fang; Surani, M. Azim; Jaenisch, Rudolf; Zwaka, Thomas P. (Elsevier, 2011-10)
    Despite recent critical insights into the pluripotent state of embryonic stem cells (ESCs), there is little agreement over the inaugural and subsequent steps leading to its generation [1, 2, 3 and 4]. Here we show that ...
  • Schloerb, David W.; Lahav, Orly; Desloge, Joseph G.; Srinivasan, Mandayam A. (Institute of Electrical and Electronics Engineers, 2010-04)
    BlindAid is a virtual environment (VE) system that enables blind people to more easily learn about new environments on their own. The system is implemented on a desktop personal computer with a Phantom® haptic interface ...
  • Divi, Vijay; Wornell, Gregory W. (Institute of Electrical and Electronics Engineers, 2009-05)
    The performance of time-interleaved analog-to-digital converters is often significantly degraded by timing mismatch errors. We develop methods for performing blind calibration of such converters, i.e., for estimating the ...
  • Mueller, Amy V.; Herring, Keith T.; Staelin, David H. (Institute of Electrical and Electronics Engineers, 2009-09)
    In this paper a second-order method for blind source separation of noisy instantaneous linear mixtures is presented for the case where the signal order k is unknown. Its performance advantages are illustrated by simulations ...
  • Agarwal, Sameer; Iyer, Anand P.; Panda, Aurojit; Mozafari, Barzan; Stoica, Ion; Madden, Samuel R. (Association for Computing Machinery (ACM), 2012-08)
    In this demonstration, we present BlinkDB, a massively parallel, sampling-based approximate query processing framework for running interactive queries on large volumes of data. The key observation in BlinkDB is that one ...
  • Agarwal, Sameer; Mozafari, Barzan; Panda, Aurojit; Milner, Henry; Stoica, Ion; Madden, Samuel R. (Association for Computing Machinery (ACM), 2013-04)
    In this paper, we present BlinkDB, a massively parallel, approximate query engine for running interactive SQL queries on large volumes of data. BlinkDB allows users to trade-off query accuracy for response time, enabling ...
  • Hsu, Chia Wei; Zhen, Bo; Chua, Song-Liang; Johnson, Steven G.; Joannopoulos, John D.; Soljacic, Marin (Nature Publishing Group, 2013-07)
    From detailed numerical calculations, we demonstrate that in simple photonic crystal structures, a discrete number of Bloch surface-localized eigenstates can exist inside the continuum of free-space modes. Coupling to the ...
  • Hashikawa, K.; Naka, Masamitsu; Nakayama, D.; Matsumoto, N.; Matsuki, N.; Neve, Rachael L. (Society for Neuroscience, 2013-03)
    Humans and non-human animals learn associations of temporally contingent stimuli to better cope with the changing environment. In animal models of classical conditioning, a neutral conditioned stimulus (CS) predicts an ...
  • Gnedin, Alexander; Kerov, Sergei; Gorin, Vadim (Springer US, 2012-08)
    A block character of a finite symmetric group is a positive definite function which depends only on the number of cycles in a permutation. We describe the cone of block characters by identifying its extreme rays, and find ...
  • Yang, Wei; Durisi, Giuseppe; Koch, Tobias; Polyanskiy, Yury (Institute of Electrical and Electronics Engineers (IEEE), 2013-08)
    This tutorial paper deals with the problem of characterizing the maximal achievable rate R(n; ϵ )at a given blocklength n and error probability ϵ over block-fading channels. We review recent results that establish tight ...
  • Bonawitz, Elizabeth; Horowitz, Alexandra; Ferranti, Darlene; Schulz, Laura E. (Cognitive Science Society (U.S.), 2009-07)
    Some researchers have suggested that correlation information and information about action are bound in a single representation: “causal knowledge”. If children have only observed correlation information, do they ...
  • Monig, Jens; Ohshima, Yoshiki; Maloney, John H. (Institute of Electrical and Electronics Engineers (IEEE), 2015-10)
    Visual blocks languages offer many advantages to the beginner or “casual” programmer. They eliminate syntax issues, allow the user to work with logical program chunks, provide affordances such as drop-down menus, and ...
  • Samot, Josh; Moon, Sangjun; Shao, Lei; Zhang, Xiaohui; Xu, Feng; YoungSeok, Song; Hasan, Onur Keles; Matloff, Laura; Markel, Jordan; Demirci, Utkan (Public Library of Science, 2011-03)
    Blood banking has a broad public health impact influencing millions of lives daily. It could potentially benefit from emerging biopreservation technologies. However, although vitrification has shown advantages over traditional ...
  • Gorczynska, Iwona; Szkulmowski, M.; Grulkowski, Ireneusz; Szkulmowska, A.; Szlag, D.; Fujimoto, James G.; Kowalczyk, Andrzej; Wojtkowski, M. (SPIE, 2010-01)
    We present an application of the Joint Spectral and Time domain OCT (STdOCT) method for detection of wide range of flows in the retinal vessels. We utilized spectral/Fourier domain OCT (SOCT) technique for development of ...
