COMPASS: Navigating the Rules of Scientific Engagement

In an era of heightened competition for scarce research positions and funding, the mantra of modern academia—‘‘publish or perish’’—continues to intensify [1]. Scientists are under increasing pressure to produce as many publications as possible in ‘‘high-impact’’ journals to raise their profile among peers and influence their discipline. Yet, in recent years, another measure of significance also...

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...

Compass ∗

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...

Visual compass

We present in this paper a method to incrementally estimate the heading of a robot using panoramic images grabbed while the robot moves in its environment. We present results that show a performance similar to a magnetic compass, if not better in some cases. In particular, the heading measured by the visual compass does not drift as normal odometry does, provided the robot turns roughly by the ...
