  • Bradley, Adam D.; Bestavros, Azer (Boston University Computer Science Department, 2001-10-30)
    With web caching and cache-related services like CDNs and edge services playing an increasingly significant role in the modern internet, the problem of the weak consistency and coherence provisions in current web protocols ...
  • Davidson, Joanna (Wiley, 2012)
    Based on ethnographic research among rural Diola in Guinea-Bissau, I provide a broad view of the history and interpenetration of rice in social, political, religious, and ecological domains, while chronicling the current ...
  • Barman, Dhiman; Matta, Ibrahim (Boston University Computer Science Department, 2003-12-03)
    (This Technical Report revises TR-BUCS-2003-011) The Transmission Control Protocol (TCP) has been the protocol of choice for many Internet applications requiring reliable connections. The design of TCP has been challenged ...
  • Fonseca, Nahur; Crovella, Mark (Boston University Computer Science Department, 2004-07-06)
    One of TCP's critical tasks is to determine which packets are lost in the network, as a basis for control actions (flow control and packet retransmission). Modern TCP implementations use two mechanisms: timeout, and fast ...
  • Kim, Robyn S.; Seitz, Aaron R.; Shams, Ladan (Public Library of Science, 2008-1-30)
    BACKGROUND. Studies of perceptual learning have largely focused on unisensory stimuli. However, multisensory interactions are ubiquitous in perception, even at early processing stages, and thus can potentially play a role ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2008-07-29)
    Berke et al. (2008) reported that beta oscillations occur during the learning of hippocampal place cell receptive fields in novel environments. Place cell selectivity can develop within seconds to minutes, and can remain ...
  • Kfoury, A.J. (Boston University Computer Science Department, 1996-07-08)
    We define a unification problem ^UP with the property that, given a pure lambda-term M, we can derive an instance Gamma(M) of ^UP from M such that Gamma(M) has a solution if and only if M is beta-strongly normalizable. ...
  • Carpenter, Gail A.; Gaddam, Sai Chaitanya (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2009-04)
    Memories in Adaptive Resonance Theory (ART) networks are based on matched patterns that focus attention on those portions of bottom-up inputs that match active top-down expectations. While this learning strategy has proved ...
  • Shinn-Cunningham, Barbara; Santarelli, Scott; Kopco, Norbert (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-10)
    To a first-order approximation, binaural localization cues are ambiguous: a number of source locations give rise to nearly the same interaural differences. For sources more than a meter from the listener, binaural localization ...
  • Gruenwald, Alexander; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-05)
    A key problem in cognitive science concerns how the brain binds together parts of an object into a coherent visual object representation. One difficulty that this binding process needs to overcome is that different parts ...
  • Rachlin, John; Cohen, Dikla Dotan; Cantor, Charles; Kasif, Simon (2006-11-28)
    Network models are a fundamental tool for the visualization and analysis of molecular interactions occurring in biological systems. While broadly illuminating the molecular machinery of the cell, graphical representations ...
  • Carpenter, Gail; Martens, Siegfried; Mingolla, Ennio; Ogas, Ogi; Sai, Chaitanya (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-10)
    Ongoing research at Boston University has produced computational models of biological vision and learning that embody a growing corpus of scientific data and predictions. Vision models perform long-range grouping and ...
  • Cohen, Michael A.; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-06)
    A biomechanical model of the human oculomotor plant kinematics in 3-D as a function of muscle length changes is presented. It can represent a range of alternative interpretations of the data as a function of one parameter. ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-10)
  • Martin, David M.; Rajagopalan, Sivaramakrishnan; Rubin, Aviel D. (Boston University Computer Science Department, 1996-10-29)
    This paper explores the problem of protecting a site on the Internet against hostile external Java applets while allowing trusted internal applets to run. With careful implementation, a site can be made resistant to current ...
  • Athitsos, Vassilis; Sclaroff, Stan (Boston University Computer Science Department, 2004-02-13)
    This paper introduces an algorithm that uses boosting to learn a distance measure for multiclass k-nearest neighbor classification. Given a family of distance measures as input, AdaBoost is used to learn a weighted distance ...
  • Athitsos, Vassilis; Alon, Jonathan; Sclaroff, Stan; Kollios, George (Boston University Computer Science Department, 2003-11-24)
    This paper introduces BoostMap, a method that can significantly reduce retrieval time in image and video database systems that employ computationally expensive distance measures, metric or non-metric. Database and query ...
  • Mulcahy, Seann P. (2011-10-11)
    A simple experiment to demonstrate nucleophilic addition to a carbonyl. Sodium borohydride-mediated reduction of fluorenone is a fast and high-yielding reaction that is suitable for beginning students. Students isolate ...
