0:00:04well active some motion is indispensable for several development on physiological processes within an organism
0:00:11as an example here receive movements of and female sells it's one two blood vessel
0:00:16natural it in an embryo
0:00:18some nuclei are traced and the trajectories regular locally ordered movement that trying to understand
0:00:25how such cells can organized in movement
0:00:28it performs experiment it's cultures
0:00:31so as a grown on the rigid plastic dish gorgeous substrate and seated in patches
0:00:35in which a cell density of is very high
0:00:37we use an immortalised human carotene aside satellite in packets which we could be used
0:00:41in the culture in the manipulating the standard cell culture lab
0:00:45the subcultures we've grown in the amount culture medium supplement with volunteer in court you
0:00:49plates captain a standard could be uttered are fighting for optimal temperature humidity and that
0:00:54was here
0:00:55sound movements within cultures recorded by automating microscope setup
0:01:00which monitored spiral cultures for several hours up to a couple days applied to sell
0:01:05culture plate into transparent spinning theatre melted and the power stage of inadvertent microscope
0:01:10this stage talking rate are provided for standard console culture conditions
0:01:15we selected to fill the view manually and store their positions in the computer
0:01:20the time let's program
0:01:22stage to distort positions every ten minutes and capture single images which are then used
0:01:27for time that's videos or motion analysis
0:01:31this time lapse according shows the dynamics within a high density batch of articulators sells
0:01:35a cohesive slowed expand patch by participating in a bigger as turbulent like low within
0:01:41the bulk of the model year
0:01:44the spontaneous outflow is sensitive to perturbations selsa vacation if a cow simulator regions dissertation
0:01:51the common window is break up into smaller groups and relative movement between cells the
0:01:56sheer increases
0:01:57this animation shows the changes yes in the place that's adaptation complex things oneself in
0:02:03screens
0:02:04the other way actually indicates asset that usual sides of the way so as to
0:02:09what is speech other somebody shown complex this must break right was must form as
0:02:14these processes take time and here and complex two separate things as adults only in
0:02:19particular we expect lasted region size present in the front of things out
0:02:24the same impact model of adaptive stress and that regions make on something the spatially
0:02:29distributed you genocide interesting "'cause" i can actually encourage us to have like the dynamics
0:02:36of distributes that fusion complex things the proposed dynamics resides in an estimate should distribution
0:02:42of thing directions
0:02:44these dynamics was implemented in an appropriate set of the reports more done in this
0:02:49movie and also has also proposed by the red ones that the use the left
0:02:53panel shows the traditional dynamics by the one on the right existing annotation the proposed
0:02:59dynamics acting between stars of the same colour
0:03:02simulations performing complement of the first we get an inter can locally order dynamics the
0:03:09meat of a moving streams can be part of parameters characterizing statistician dynamics in general
0:03:16the streams that holder you decide that you hunting stress the what do not have
0:03:20a longer lifetime
0:03:22probabilistic the use of both experiments and simulations we can be average velocity field surrounding
0:03:28the range cells
0:03:29well known to fulfill review larger correlations one compare them or an isotropic feel strongly
0:03:36treat itself
0:03:38simulations show that this implies entropy is controlled by the stress condition between cells stronger
