Elastic J/psi production at HERA

Aktas, A.; Andreev, V.; Anthonis, T.; Antunovic, B.; Aplin, S.; Asmone, A.; Astvatsatourov, A.; Babaev, A.; Backovic, S.; Bahr, J.; Baghdasaryan, A.; Baranov, P.; Barrelet, E.; Bartel, W.; Baudrand, S.;... (2006)

DESY-HERA. Measurement of cross sections for elastic production of J/PSI in photoproduction and electroproduction in E P collisions at incident electron (positron) energy of 27.5 GeV and proton energy 920 GeV. The data come from the 1999-2000 running periods with mainly positrons and have an integrated luminosity of 55 pb-1. Results are presented up to Q**2 of 80 GeV**2.. The mean values shown are the bin centre values in the indicated regions.

Nonlinear optical endoscopy based on a double-clad photonic crystal fiber and a MEMS mirror

Ling Fu; Ankur Jain; Huikai Xie; Charles Cranfield; Min Gu (2006)
Publisher: Figshare
Two-photon fluorescence and second harmonic generation microscopy have enabled functional and morphological in vivo imaging. However, in vivo applications of those techniques to living animals are limited by bulk optics on a bench top. Fortunately, growing functionality of fiber-optic devices and miniaturization of scanning mirrors stimulate the race to develop nonlinear optical endoscopy. In this paper, we report on a prototype of a nonlinear optical endoscope based on a double-clad photonic...

Full-field time-encoded frequency-domain optical coherence tomography

Boris Považay; Angelika Unterhuber; Boris Hermann; Harald Sattmann; Holger Arthaber; Wolfgang Drexler (2006)
Publisher: Figshare
Ultrahigh axial resolution surface profiling as well as volumetric optical imaging based on time encoded optical coherence tomography in the frequency domain without any mechanical scanning element is presented. A frequency tuned broad bandwidth titanium sapphire laser is interfaced to an optical microscope (Axioskop 2 MAT, Carl Zeiss Meditec) that is enhanced with an interferometric imaging head. The system is equipped with a 640 × 480 pixel CMOS camera, optimized for the 800 nm wavelength t...

(2006): Ptychopteridae — a family of flies (Diptera) new to the Neotropical Region and description of a new species. Zootaxa 1351: 61-68, DOI: 10.5281/zenodo.174523

High dimensional statistical inference and random matrices

Johnstone, Iain (2006)
Publisher: Instituto de Ciencias Matemáticas (ICMAT)
Multivariate statistical analysis is concerned with observations on several variables which are thought to possess some degree of inter-dependence. Driven by problems in genetics and the social sciences, it first flowered in the earlier half of the last century. Subsequently, random matrix theory (RMT) developed, initially within physics, and more recently widely in mathematics. While some of the central objects of study in RMT are identical to those of multivariate statistics, statistical...

European Union enlargement. The European constitution. Economic challenges. Innovative products and services. Topics: This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures such as how satisfied they were witht heir present lives, whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, what their individual country´s goals should be, and how they view...

Topology of optical vortex lines formed by the interference of three, four, and five plane waves

Kevin O’Holleran; Miles J. Padgett; Mark R. Dennis (2006)
Publisher: Figshare
When three or more plane waves overlap in space, complete destructive interference occurs on nodal lines, also called phase singularities or optical vortices. For super positions of three plane waves, the vortices are straight, parallel lines. For four plane waves the vortices form an array of closed or open loops. For five or more plane waves the loops are irregular. We illustrate these patterns numerically and experimentally and explain the three-, four- and five-wave topologies with a phas...
