The collision cross-section of a simple collision model, such as the hard sphere or variable hard sphere (VHS) is made to vary from cell to cell, based on the time-averaged cell temperature and the required viscosity at that temperature.
That ruled out a simple collision with a rock, or an internal malfunction of the ship's own weapons systems.
A simple collision channel model had been considered but with the possibility of spatial reuse.
In a simple collision occurring on a 2D substrate where cells can freely move, it is possible to measure cell velocity before and after collisions (Fig. 1c).
Thus, transcriptional interference seems indeed restricted to the 3' ends of genes, suggesting a role of transcription termination; conversely, the restriction to 3' ends seems not consistent with the simple collision of two polymerases as the source of reduced co-expression.
These truncations cannot result from simple collisions of saltons during saltation, which should produce a flat erosive plane, as in the aeolian context.
It was the simplest collision of the set, and one of the most exhilarating.
The analysis is not quite a simple comparison of collision angles; impulsive walking splits the collision into two smaller and therefore less costly collisions (figure 1 a, b).
There is (simple) collision detection against the boundaries of the map and the colored "blocking" blocks, but not against the karts, so you can't crash into the other drivers.
An elephant, a poacher, a collision of desperate needs.
