The Compass Experiment and the Measurement of the Gluon Polarisation
COMPASS, a new fixed target experiment at CERN, aimed at the study of nucleon spin structure and hadron spectroscopy, has started to collect physics data in Autumn 2001. This paper describes the COMPASS apparatus and the measurement of the gluon polarisation ∆G/G. The apparatus consists in a solid state polarised target and a two stage spectrometer with high resolution tracking, particle identi...
متن کاملPolarisation Signals
Humans are fascinated by the colour vision, colour signals and ‘dress codes’ of other animals as we can see colour. This property of light may be useful for increasing the contrast of objects during foraging, defence, camouflage and sexual communication. New research, largely from the last decade, now suggests that polarisation is a quality of light also used in signalling and may contain infor...
متن کاملPolarisation vision
adhesion proteins implicated in integrin activation, including integrin-linked kinase and the filamin-binding protein, migfilin (Figure 1). However, whether these interactions are important for activation or for kindlin-mediated integrin signaling, focal adhesion formation, and cell spreading is unclear and elucidation of the mechanisms of kindlin function will likely require detailed knowledge...
متن کاملSciamachy Polarisation Sensitivity
SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) is one of the Earth observation research instruments to be included as part of the payload of the ESA (European Space Agency) ENVISAT-1 platform to be launched in the year 2000. The main scientific objective of SCIAMACHY is to measure distributions of a number of chemically important atmospheric trace species on a...
متن کاملPolarisation of Graded Bundles
We construct the full linearisation functor which takes a graded bundle of degree k (a particular kind of graded manifold) and produces a k-fold vector bundle. We fully characterise the image of the full linearisation functor and show that we obtain a subcategory of k-fold vector bundles consisting of symmetric k-fold vector bundles equipped with a family of morphisms indexed by the symmetric g...
