Abstract The aim of this paper is to present a new, analytical, method for computing the exact number relative equilibria in planar, circular, restricted 4-body problem celestial mechanics. new approach allows very efficient computer-aided proof, and opens potential pathway proving harder instances n -body problem.

We investigate the outcomes of measurements on correlated, few-body quantum systems described by a quaternionic quantum mechanics that allows for regions of quaternionic curvature. We find that a multi-particle interferometry experiment using a correlated system of four nonrelativistic, spin-half particles has the potential to detect the presence of quaternionic curvature. Two-body systems, how...

This chapter describes research conducted to analyze and better understand what is compelling about particular body-movement-based design patterns in Nintendo Wii games, towards innovating new possibilities for social and emotional experience with movementbased games and other interactive experiences. The authors analyzed games from diverse genres, to generate a bottom-up set of dimensions and ...

We distinguish between, and discuss the applicability of, two levels of rigidity in rigid-body collision modeling. For rigidity in the strong, force-response, sense collisional contact deformations must be highly localized. The bodies then move according to second order rigid-body mechanics during the collision. Incremental collision laws and most collision models using continuum mechanics for ...

Foraging mode has molded the evolution of many aspects of lizard biology. From a basic sit-and-wait sprinting feeding strategy, several lizard groups have evolved a wide foraging strategy, slowly moving through the environment using their highly developed chemosensory systems to locate prey. We studied locomotor performance, whole-body mechanics and gaits in a phylogenetic array of lizards that...
