(Boston University Computer Science Department, 2009-03-09)We study the problem of preprocessing a large graph so that point-to-point shortest-path queries can be answered very fast. Computing shortest paths is a well studied problem, but exact algorithms do not scale to huge ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-06-08)Perceptual grouping is well-known to be a fundamental process during visual perception, notably grouping across scenic regions that do not receive contrastive visual inputs. Illusory contours are a classical example of ...
-
(Public Library of Science, 2010-1-26)Invasive species have tremendous detrimental ecological and economic impacts. Climate change may exacerbate species invasions across communities if non-native species are better able to respond to climate changes than ...

Favoring Generalists over Specialists: How Attentional Biasing Improves Perceptual Category Learning(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-05)A model of cortical learning is proposed, which incorporates supervised feedback using two forms of attention: (i) feature-specific attention which allows the network to learn associations between specific feature conjunctions ...

(BioMed Central, 2009-9-18)BACKGROUND. Protein-protein interactions (PPIs) play fundamental roles in nearly all biological processes, and provide major insights into the inner workings of cells. A vast amount of PPI data for various organisms is ...
-
(Boston University Computer Science Department, 2000-12-15)Traditional approaches to receiver-driven layered multicast have advocated the benefits of cumulative layering, which can enable coarse-grained congestion control that complies with TCP-friendliness equations over large ...
-
(2012-01-03)A microwave-accelerated synthesis of volatile aromatic esters is described in this convenient Fisher esterification reaction. Students perform a liquid-liquid extraction to isolate crude product which they purify by ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-12)Under natural viewing conditions small movements of the eye, head, and body prevent the maintenance of a steady direction of gaze. It is known that stimuli tend to fade when they a restabilized on the retina for several ...
-
(Boston University Computer Science Department, 1993-08-11)We prove that first order logic is strictly weaker than fixed point logic over every infinite classes of finite ordered structures with unary relations: Over these classes there is always an inductive unary relation which ...
-
(2012-07-09)Authenticity, defined as the discovery or revelation of origin or essence, is a primary value orientation in modern society, and the consumption of food and drink is one of the most potent modes for seeking and affirming ...

(Boston University Computer Science Department, 2005-05-19)Moving cameras are needed for a wide range of applications in robotics, vehicle systems, surveillance, etc. However, many foreground object segmentation methods reported in the literature are unsuitable for such settings; ...
-
(2011-10-15)An introductory laboratory on the identification of analgesics in an unknown sample. Ideal for the first week of an organic chemistry sequence to get students familiar with their surroundings. Students extract, isolate, ...
-
(Boston University Computer Science Department, 2009)Recent advances in processor speeds, mobile communications and battery life have enabled computers to evolve from completely wired to completely mobile. In the most extreme case, all nodes are mobile and communication takes ...
-
(Boston University Computer Science Department, 2005-08-08)A weak reference is a reference to an object that is not followed by the pointer tracer when garbage collection is called. That is, a weak reference cannot prevent the object it references from being garbage collected. ...
-
(CS Department, Boston University, 2010-08-24)Desirable application performance is typically guaranteed through the use of Service Level Agreements (SLAs) that specify fixed fractions of resource capacities that must be allocated for unencumbered use by the application. ...
