Development of launch mechanism in ball shooting machine with four rollers
Nihon Kikai Gakkai ronbunshu, 2017 Ball shooting machine (pitching machine) is used for practicing ball sports, and it is widely prevalent. However, there are few pitching machines that can throw a ball with a gyro spin, such as a football or rifle bullet, in which the axis of the ball ...

Axisymmetric landslides on top-shaped asteroids [PDF]
EPJ Web of Conferences, 2021 Spin rates of minor planets or asteroids are known to have been affected by several agents including but not limited to tidal fly-bys, impacts and solar radiation. Surface processes like landslides occur as a result of such rotational changes.

FOSSIL. I. The Spin Rate Limit of Jupiter Trojans [PDF]
The Planetary Science Journal, 2021 Abstract Rotation periods of 53 small (diameters 2 km < D < 40 km) Jupiter Trojans (JTs) were derived using the high-cadence lightcurves obtained by the FOSSIL phase I survey, a Subaru/Hyper Suprime-Cam intensive program. These are the first reported periods measured for JTs with D < 10 km. We found a lower limit of the rotation

INFORMATION TRANSFER RATES IN SPIN QUANTUM CHANNELS [PDF]
International Journal of Quantum Information, 2007 We analyze the communication efficiency of quantum information transfer along unmodulated spin chains by computing the communication rates of various protocols. The effects of temporal correlations are discussed, showing that they can be exploited to boost the transmission efficiency.

Spin exchange rates in proton-hydrogen collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 The spin temperature of neutral hydrogen, which determines the optical depth and brightness of the 21 cm line, is determined by the competition between radiative and collisional processes. Here we examine the role of proton-hydrogen collisions in setting the spin temperature.

Ultrafast circular polarization oscillations in spin-polarized vertical-cavity surface-emitting laser devices [PDF]
, 2010 Spin-polarized lasers offer new encouraging possibilities for future devices. We investigate the polarization dynamics of electrically pumped vertical-cavity surface-emitting lasers after additional spin injection at room temperature.
