  • Jin, Shudong; Bestavros, Azer (Boston University Computer Science Department, 1999-10-10)
    Temporal locality of reference in Web request streams emerges from two distinct phenomena: the popularity of Web objects and the {\em temporal correlation} of requests. Capturing these two elements of temporal locality is ...
  • Bhatt, Rushi; Carpenter, Gail A.; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2006-07-28)
    A neural model is proposed of how laminar interactions in the visual cortex may learn and recognize object texture and form boundaries. The model brings together five interacting processes: region-based texture classification, ...
  • Oddo, Scott; Beck, Jacob; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-03)
    We compare the perceived segregation of element-arrangement patterns1 which are composed of two types of squanes arranged in vertical stripes in the top and bottom regions and in a checkerboard in the middle region. The ...
  • Grossberg, Stephen; Pessoa, Luiz (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-08)
    A widespread view is that most of texture segregation can be accounted for by differences in the spatial frequency content of texture regions. Evidence from both psychophysical and physiological studies indicate, however, ...
  • Rosenzweig, Daphne (International Center for East Asian Archaeology and Cultural History, Boston University, 1950-1969)
  • Samz, Charles (International Center for East Asian Archaeology and Cultural History, Boston University, )
  • Grossberg, Stephen; Hwang, Seungwoo; Mingolla, Ennio (Boston University Computer Science Department, 2001-04)
    This article further develops the FACADE neural model of 3-D vision and figure-ground perception to quantitatively explain properties of the McCollough effect. The model proposes that many McCollough effect data result ...
  • Casile, Antonino; Rucci, Michele (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2005-01)
    Under natural viewing conditions, the physiological inotability of visual fixation keeps the projection of the stimulus on the retina in constant motion. After eye opening, chronic exposure to a constantly moving retinal ...
  • Guenther, Frank; Hampson, Michelle; Johnson, Dave (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-02)
    Does the speech motor control system utilize invariant vocal tract shape targets of any kind when producing phonemes? We present a four-part theoretical treatment favoring models whose only invariant targets are auditory ...
  • Lindholm, Charles (Taylor & Francis, 2008-01-31)
  • Chen, Ming-Huei; Larson, Martin G; Hsu, Yi-Hsiang; Peloso, Gina M; Guo, Chao-Yu; Fox, Caroline S; Atwood, Larry D; Yang, Qiong (BioMed Central, 2010-5-14)
    BACKGROUND. Genome-wide association (GWA) studies that use population-based association approaches may identify spurious associations in the presence of population admixture. In this paper, we propose a novel three-stage ...
  • Carpenter, Gail A.; Rubin, Mark A.; Streilein, William W. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-05)
    The ARTMAP-FD neural network performs both identification (placing test patterns in classes encountered during training) and familiarity discrimination (judging whether a test pattern belongs to any of the classes encountered ...
  • Klausner, J. M.; Abu-Abid, S.; Alexander, J. S.; Hanshke-Mineau, R.; Goldman, G.; Morel, N.; Valeri, C. R.; Shepro, D.; Hechtman, H. B. (Hindawi Publishing Corporation, 1994)
    The study tests the role of thromboxane in modulating microvascular permeability in vitro. Cultured monolayers of bovine aortic endothelial cells were challenged with the thromboxane (Tx) mimic U46619. This led to disassembly ...
  • Braoudakis, Spyridon; Bestavros, Azer (Boston University Computer Science Department, 1994)
    Various concurrency control algorithms differ in the time when conflicts are detected, and in the way they are resolved. In that respect, the Pessimistic and Optimistic Concurrency Control (PCC and OCC) alternatives represent ...
  • Harchol-Balter, Mor; Crovella, Mark E.; Murta, Cristina D. (Boston University Computer Science Department, 1997-10-31)
    We examine the question of whether to employ the first-come-first-served (FCFS) discipline or the processor-sharing (PS) discipline at the hosts in a distributed server system. We are interested in the case in which service ...
  • Wood, Richard J.; Schwartz, Eric L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-10)
    Shear has been known to exist for many years in the topographic structure of prirnary visual cortex, but has received little attention in the modeling literature. Although the topographic map of V1 is largely conformal ...
  • Tal, D.; Schwartz, E. L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-11)
    Optical imaging methods have revealed the spatial arrangement of orientation columns across striate cortex, usually summarized in terms of two measurements at each cortical location: (i) a "best" stimulus orientation, ...
  • Raizada, Rajeev D.S.; Grossberg, Stephen (Boston University Computer Science Department, 2001-12-03)
    One of the most exciting and open research frontiers in neuroscience is that of seeking to understand the functional roles of the layers of cerebral cortex. New experimental techniques for probing the laminar circuitry of ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2006-10)
    A key goal of computational neuroscience is to link brain mechanisms to behavioral functions. The present article describes recent progress towards explaining how laminar neocortical circuits give rise to biological ...
  • Gabay, Yarom; Kfoury, Assaf J. (Boston University Computer Science Department, 2006-12-15)
    Weak references provide the programmer with limited control over the process of memory management. By using them, a programmer can make decisions based on previous actions that are taken by the garbage collector. Although ...
