(Dove Medical Press, 2006)This study compared patterns of frontal-lobe dysfunction in alcoholics with Korsakoff's syndrome (KS: n = 9), non-Korsakoff alcoholics (AL: n = 28), patients with Parkinson's disease (PD: n = 18), and patients with rupture ...

Perceived Texture Segregation in Chromatic Element-Arrangement Patterns: High Intensity Interference(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-03)An element-arrangement pattern is composed of two types of elements that differ in the ways in which they are arranged in different regions of the pattern. We report experiments on the perceived segregation of chromatic ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1991-12)How do human observers perceive a coherent pattern of motion from a disparate set of local motion measures? Our research has examined how ambiguous motion signals along straight contours are spatially integrated to obtain ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-08)Lightness constancy requires the visual system to somehow "parse" the input scene into illumination and reflectance components. Experiments on the perception of lightness for 3-D curved objects show that human observers ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-11)The experiments reported herein probe the visual cortical mechanisms that control near-far percepts in response to two-dimensional stimuli. Figural contrast is found to be a principal factor for the emergence of percepts ...
-
(Public Library of Science, 2006-12-20)Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases. The threshold at which CFF occurs has been shown to ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-10)The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development. The effect is characterized by a warping of perceptual space near phonemic category centers. ...

(Boston University Computer Science Department, 1996-08-05)This paper addresses the problem of analyzing performance of WWW servers. The web has experienced a phenomenal growth and has become the most popular Internet application. As a consequence of its large popularity, the ...
-
(Boston University Computer Science Department, 1998-10-23)Version 1.1 of the Hyper Text Transfer Protocol (HTTP) was principally developed as a means for reducing both document transfer latency and network traffic. The rationale for the performance enhancements in HTTP/1.1 is ...
-
(Boston University Computer Science Department, 1993-02-05)Speculative Concurrency Control (SCC) [Best92a] is a new concurrency control approach especially suited for real-time database applications. It relies on the use of redundancy to ensure that serializable schedules are ...
-
(Frontiers Research Foundation, 2008-04-08)The neocortex generates rhythmic electrical activity over a frequency range covering many decades. Specific cognitive and motor states are associated with oscillations in discrete frequency bands within this range, but it ...
-
(Boston University Computer Science Department, 2004-11-02)A novel technique to detect and localize periodic movements in video is presented. The distinctive feature of the technique is that it requires neither feature tracking nor object segmentation. Intensity patterns along ...
-
(Boston University Computer Science Department, 2002)Growing interest in inference and prediction of network characteristics is justified by its importance for a variety of network-aware applications. One widely adopted strategy to characterize network conditions relies on ...

(BioMed Central, 2006-5-22)BACKGROUND: High-throughput genotyping generates vast amounts of data for analysis; results can be difficult to summarize succinctly. A single project may involve genotyping many genes with multiple variants per gene and ...
-
(BioMed Central, 2008-1-28)BACKGROUND. Phosphatidylinositol (PI) 3-kinase is activated by a variety of growth factor receptors and the PI 3-kinase/Akt signaling pathway is a key regulator of cell proliferation and survival. The downstream targets ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-12)Visual search is extended from the domain of polygonal figures presented on a uniform field to photo-realistic scenes containing target objects in dense, naturalistic backgrounds. The target in a trial is a computer-rendered ...
