Production of charmed and beauty mesons and baryons in hadron–nucleon collisions at not very high energy is considered in the framework of the Quark–Gluon String Model. We take into account the possible corrections to the model which disappear at asymptotically high energies but could be important at comparatively low energies, essentially in the case of heavy flavour production. The case of nu...

This work presents a novel study of the notion of facial attractiveness in a machine learning context. To this end, we collected human beauty ratings for data sets of facial images and used various techniques for learning the attractiveness of a face. The trained predictor achieves a significant correlation of 0.65 with the average human ratings. The results clearly show that facial beauty is a...

The production of charm and beauty quarks in ep interactions has been measured with the ZEUS detector at HERA for squared four-momentum exchange Q 2 > 20 GeV 2 , using an integrated lu-minosity of 126 pb −1. Charm and beauty quarks were identified through their decays into muons. Cross sections are presented for muon transverse momenta p µ T > 1.5 GeV and pseudorapidities −1.6 < η µ < 2.3. The ...

The Engagement With Beauty Scale (EBS), designed from the aesthetics of I. Kant (1790/1987), G. W. F. Hegel (ca. 1835/1993), and T. Aquinas (ca. 1260/1947) and the psychological work of J. Haidt (J. Haidt & D. Keltner, 2004), measures engagement with natural, artistic, and moral beauty. In Studies 1 and 2, the authors describe scale construction, exploratory factor analysis, confirmatory factor...

Using an objective measure of executive facial attractiveness we find that shareholders value beauty. Specifically, more attractive executives are associated with a higher abnormal return around the announcement of their appointment as CEO. These results are strongest for insider appointments and relatedly, more attractive facial features increase the likelihood of an executive winning a tourna...

It has been well established that homing pigeons are able to use the Earth's magnetic field to obtain directional information when returning to their loft and that their magnetic compass is based, at least in part, on the perception of magnetic inclination. Magnetic inclination has also been hypothesized in pigeons and other long-distance navigators, such as sea turtles, to play a role providin...
