We report a detection of the coherent distortion of faint galaxies arising from gravitational lensing by foreground structures. This “cosmic shear” is potentially the most direct measure of the mass… (More)

Molecular surfaces are fitted to each other by a new solution to the problem of docking a ligand into the active site of a protein molecule. The procedure constructs patterns of points on the… (More)

A method has been developed for aligning segments of several sequences at once. The number of search steps depends only polynomially on the number of sequences, instead of exponentially, because most… (More)

We present the first application of the 3D cosmic shear method developed in Heavens et al. (2006) and the geometric shear-ratio analysis developed in Taylor et al. (2006), to the COMBO-17 data set.… (More)

We report the results of a cosmic shear survey using the 4.2m W illiam Herschel Telescope on La Palma, to a depth of R = 25.8 (z ≈ 0.8), over 4 square degrees. The shear correlation functions are… (More)

We adapt the Jain–Taylor (2003) shear-ratio geometric lensing method to measure the dark energy equation of state, w = p v /ρ v and its time derivative from dark matter haloes in cosmologies with… (More)

Doppler lensing is the apparent change in object size and magnitude due to peculiar velocities. Objects falling into an overdensity appear larger on its near side, and smaller on its far side, than… (More)
