ORB: An efficient alternative to SIFT or SURF
Feature matching is at the base of many computer vision problems, such as object recognition or structure from motion. Current methods rely on costly descriptors for detection a...

Amazon's Mechanical Turk
Amazon’s Mechanical Turk (MTurk) is a relatively new website that contains the major elements required to conduct research: an integrated participant compensation system; a larg...
Free Energy of a Nonuniform System. I. Interfacial Free Energy
It is shown that the free energy of a volume V of an isotropic system of nonuniform composition or density is given by : NV∫V [f0(c)+κ(▿c)2]dV, where NV is the number of molecul...
Functional connectivity in the motor cortex of resting human brain using echo‐planar mri
Abstract An MRI time course of 512 echo‐planar images (EPI) in resting human brain obtained every 250 ms reveals fluctuations in signal intensity in each pixel that have a physi...
Stellar population synthesis at the resolution of 2003
We present a new model for computing the spectral evolution of stellar populations at ages between 100,000 yr and 20 Gyr at a resolution of 3 A across the whole wavelength range...
The Large Scale Structure of Space-Time
Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to d...
TCS: a computer program to estimate gene genealogies
Phylogenies are extremely useful tools, not only for establishing genealogical relationships among a group of organisms or their parts (e.g. genes), but also for a variety of re...
Not So Different After All: A Cross-Discipline View Of Trust
The article discusses trust theory, multidisciplinary research, and trust between organizations. The analysis of trust is based on four questions: whether scholars can agree on ...
<i>Review</i> : Knowledge Management and Knowledge Management Systems: Conceptual Foundations And Research Issues1,2
Knowledge is a broad and abstract notion that has defined epistemological debate in western philosophy since the classical Greek era. In the past few years, however, there has b...
Measuring the Accuracy of Diagnostic Systems
Diagnostic systems of several kinds are used to distinguish between two classes of events, essentially "signals" and "noise." For them, analysis in terms of the "relative operat...
Statistical parametric maps in functional imaging: A general linear approach
Abstract Statistical parametric maps are spatially extended statistical processes that are used to test hypotheses about regionally specific effects in neuroimaging data. The mo...
