In vivo anterior scleral morphometry, axial length and myopia.
Contact lens & anterior eye : the journal of the British Contact Lens Association, 2020 PURPOSE To in-vivo quantify differences in anterior scleral shape between myopes and emmetropes and relate them with axial length and refractive power. METHODS Forty-two participants (84 eyes) were included in this study.

Powder alignment system for anisotropic bonded NdFeB Halbach cylinders [PDF]
, 2000 A Halbach cylinder, fabricated from pre-magnetized sintered NdFeB magnet segments, is proposed for the powder aligning system during the compression or injection moulding of anisotropic bonded Halbach oriented NdFeB ring magnets. The influence of leading

Marked Length Spectral determination of analytic chaotic billiards with axial symmetries
, 2019 We consider billiards obtained by removing from the plane finitely many strictly convex analytic obstacles satisfying the non-eclipse condition. The restriction of the dynamics to the set of non-escaping orbits is conjugated to a subshift, which provides

Momentum spectroscopy of 1D phase fluctuations in Bose-Einstein condensates [PDF]
, 2003 We measure the axial momentum distribution of Bose-Einstein condensates with an aspect ratio of 152 using Bragg spectroscopy. We observe the Lorentzian momentum distribution characteristic of one-dimensional phase fluctuations. The temperature dependence
