Persistent influence of precession on northern ice sheet variability since the early Pleistocene
Science, 2022 Prior to ~1 million years ago (Ma), variations in global ice volume were dominated by changes in obliquity; however, the role of precession remains unresolved. Using a record of North Atlantic ice rafting spanning the past 1.7 million years, we find that

Periodicity in fast radio bursts due to forced precession by a fallback disk [PDF]
Research in Astronomy and Astrophysics, 2020 Recently, a 16-day periodicity in a fast radio burst was reported. We propose that this 16-day periodicity may be due to forced precession of the neutron star by a fallback disk.

Precession of timelike bound orbits in Kerr spacetime [PDF]
The European Physical Journal C, 2020 Astrometric observations of S-stars provide a unique opportunity to probe the nature of Sagittarius-A* (Sgr-A*). In view of this, it has become important to understand the nature and behavior of timelike bound trajectories of particles around a massive ...

Long-period nutational-precessional motions of the instantaneous Earth rotation pole
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Precession Intuitively Explained
Frontiers in Physics, 2019 Formal explanations of the dynamics of free and heavy tops are considered to be known for centuries. However, intuitive understanding of their unexpected behavior is still a challenge.

Phase precession in the human hippocampus and entorhinal cortex
bioRxiv, 2020 Knowing where we are, where we have been, and where we are going is critical to many behaviors, including navigation and memory. One potential neuronal mechanism underlying this ability is phase precession, in which spatially tuned neurons represent ...

Proceedings, 2018 In the off-spin bowling grip, the ball is clamped between index and middle fingers. Spin bowlers attempt to select a spread angle between these two fingers that achieves comfort and optimises performance.
