How Iris Recognition Works

by John Daugman , 2003
"... Algorithms developed by the author for recogniz-ing persons by their iris patterns have now been tested in six field and laboratory trials, producing no false matches in several million comparison tests. The recognition principle is the failure of a test of statis-tical independence on iris phase st ..."

MR Diffusion Tensor Spectroscopy and Imaging

by Peter J. Basser, James Mattiello, Denis LeBihan , 1994
"... This paper describes a new NMR imaging modality-MR diffusion tensor imaging. It consists of estimating an effective diffusion tensor, Deff, within a voxel, and then displaying useful quantities derived from it. We show how the phenomenon of anisotropic diffusion of water (or metabolites) in anisotro ..."
Abstract - Cited by 384 (11 self) - Add to MetaCart
invariants of Deft, which are independent of the tissue's orientation in the laboratory frame of reference, reveal useful information about molecular mobility reflective of local microstructure and anatomy. Inherently, tensors (like De"f) describing transport processes in anisotropic media contain

Reevaluating Amdahl’s law

by John L. Gustafson - Commun. ACM , 1988
"... At Sandia National Laboratories, we are currently en-gaged in research involving massively parallel process-ing. There is considerable skepticism regarding the via-bility of massive parallelism; the skepticism centers around Amdahl’s law, an argument put forth by Gene Amda.hl in 1967 [l] that even w ..."

Mass-SpectrometricDeterminationof SerumCortisol:Comparisonof Data fromTwo IndependentLaboratories

by Simon J. Gaskeil, Lothar Sleckmann
"... Isotope dilutionand mass spectrometry were used in two independentlaboratoriesto determinecortisolin 15 plasma and serum pools used in the British and German national schemes for the external quality assessment of routine assays. For the concentration range 240-700 nmol/L, differ-ences between the d ..."

Developments in the Measurement of Subjective Well-Being

by Daniel Kahneman , Alan B Krueger - Psychological Science. , 1993
"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

. . . . For instance, how much an individual likes or dislikes the activity 'painting one's house,' in conjunction with the amount of time one spends in painting the house, is as important determinant of well-being independent of how satisfied one feels about having a freshly painted house

The psychology of prejudice: In-group love or out-group hate

by Marilynn B. Brewer - Journal of Social Issues , 1999
"... Allport (1954) recognized that attachment to one’s ingroups does not necessarily require hostility toward outgroups. Yet the prevailing approach to the study of ethnocentrism, ingroup bias, and prejudice presumes that ingroup love and outgroup hate are reciprocally related. Findings from both cross- ..."
Abstract - Cited by 270 (0 self) - Add to MetaCart
-cultural research and laboratory experiments support the alternative view that ingroup identification is independent of negative attitudes toward outgoups and that much ingroup bias and intergroup discrimination is motivated by preferential treatment of ingroup members rather than direct hostility toward outgroup

Approach-withdrawal and cerebral asymmetry: emotional expression and brain physiology I

by Richard J. Davidson, Clifford D. Saron, Joseph A. Senulis, Paul Ekman, Wallace V. Friesen - Journal of Personality and Social Psychology , 1990
"... In this experiment, we combined the measurement of observable facial behavior with simultaneous measures of brain electrical ctivity to assess patterns of hemispheric a tivation i different regions during the experience ofhappiness and disgust. Disgust was found to be associated with right-sided act ..."

This and the accompanying report (Ekman, Davidson, & Friesen, 1990) represent the convergence of two independent yet overlapping lines of research. One is theory and evidence from Ekman
