The COMPASS future: COMPASS II
Up to now the COMPASS experiment [1] contributed with the muon beam to precise measurements of the nucleon longitudinal momentum structure. A more complete nucleon description beyond collinear approximation includes the quark intrinsic momentum distributions which are described by the Transverse Momentum Dependent (TMD) Parton Distribution Functions (PDFs) and by Generalised Parton Distribution...
متن کاملCompass ∗
The nucleon spin structure is studied at COMPASS via the measurement of the spin dependent properties of deep inelastic muon-deuteron scattering. Both inclusive and semi-inclusive observables are investigated, with the emphasis put on the latter. This allows to access, in particular, the gluon polarization (∆G/G) and the flavor decomposition of the quark helicity distributions. Results from mea...

A pair of neurons is required for nematodes to be able to navigate using the Earth's magnetic field.
متن کاملA Haptic Compass for Navigation
Over the past decade, interest has grown in using haptic cues to aid navigation, both for people with visual impairments and for people with normal vision walking in unfamiliar environments. Many devices offer GPS-based audio instructions, but haptic cues are appealing because they’re private and more practical in noisy environments. Numerous wearable devices based on vibrating motors have been...
متن کاملTwo Poles and a Compass
Rho GTPases control fundamental aspects of neutrophil chemotaxis: establishment of front and back and orientation toward the chemoattractant. Two reports in this issue show that activated Cdc42 at the leading edge helps orient the cell's axis in a signaling complex with G beta gamma, PAK1, and PIX alpha; while Rho, activated via G alpha 13, mediates formation of the uropod, which then interacts...
