The angle between the x axis and the vector of origin of the trajectory until the position defined by the coordinates ( (x,y) ) is calculated with function ( { arctan }^{2} (x,y) ).
In the present work we have mapped a significant part of the phase space of the Earth-Moon system, determining the length of the capture times and the origin of the trajectory, if it comes from the Earth direction, or from the opposite direction.
Furthermore, EG cells and iPS cells are mapped near the origin of the trajectories, whereas mouse embryo fibroblast (MEF) and fibroblast cell lines are mapped near the far end of the trajectories.
Indeed, we show that embryonic germ cells and induced pluripotent cells are mapped near the origin of the trajectories, whereas mouse embryo fibroblast and fibroblast cell lines are mapped near the far end of the trajectories.
If the engine's downtime following a stop is shorter than 30 seconds, the subsequent trajectory is considered as a continuation of the same trip if it is not going back towards the origin of the first trajectory.
Furthermore, replacing the link-based traffic assignment with path-based method is a significant boon to the model, such that one can get more insight of the origin destination and the trajectory of the drivers.
We therefore examined the temporal and spatial dependences of the angular distribution in order to further investigate the origin of the antipersistence of the trajectories and the underlying geometry of the space available for exploration.
Expression [6] also shows how the initial Rt can be estimated geometrically (without the need for parameter search or numerical optimization) from an epidemic time delay plot of surveillance data: b Rt) is the slope of the tangent at the origin of case trajectories (dashed line in Fig. 2a, b).
Evolutionary biology is the discipline that delineates our origins and the trajectory of our genealogy, illuminates why we have certain characteristics and not others, and sketches the contours of the future of our species.
In cross-cultural research, the heterogeneity of women and men who constitute the population experiencing migration needs to be accounted for, not only with respect to their country of birth, but also the country of origin, the migratory trajectory and the actual experiences of migration as they relate to health.
The method of GBL makes various assumptions and simplifications: Scatterers, the origin of kinks in the trajectory, are thin, i.e. no spatial offsets within a scatterer are taken into account.
