To the observer it is therefore intriguing\r\nwhen a moving collective exhibits order. Collective motion of flocks of birds, schools\r\nof fish or swarms of self-propelled particles or robots have been studied extensively\r\nover the past decades but the mechanisms involved in the transition from chaos to\r\norder remain unclear. Here, the interactions, that in most systems give rise to chaos,\r\nsustain order. In this thesis we investigate mechanisms that preserve, destabilize\r\nor lead to the ordered state. We show that endothelial cells migrating in circular\r\nconfinements transition to a collective rotating state and concomitantly synchronize\r\nthe frequencies of nucleating actin waves within individual cells. Consequently,\r\nthe frequency dependent cell migration speed uniformizes across the population.\r\nComplementary to the WAVE dependent nucleation of traveling actin waves, we\r\nshow that in leukocytes the actin polymerization depending on WASp generates\r\npushing forces locally at stationary patches. Next, in pipe flows, we study methods\r\nto disrupt the self–sustaining cycle of turbulence and therefore relaminarize the\r\nflow. While we find in pulsating flow conditions that turbulence emerges through a\r\nhelical instability during the decelerating phase. Finally, we show quantitatively in\r\nbrain slices of mice that wild-type control neurons can compensate the migratory\r\ndeficits of a genetically modified neuronal sub–population in the developing cortex.","lang":"eng"}],"date_published":"2023-03-23T00:00:00Z","publication_status":"published","supervisor":[{"orcid":"0000-0003-2057-2754","first_name":"Björn","last_name":"Hof","id":"3A374330-F248-11E8-B48F-1D18A9856A87","full_name":"Hof, Björn"}],"article_processing_charge":"No","month":"03","date_updated":"2023-11-30T10:55:13Z","file":[{"access_level":"closed","creator":"cchlebak","file_name":"Thesis_Riedl_2023.pdf","content_type":"application/pdf","checksum":"eba0e19fe57a8c15e7aeab55a845efb7","relation":"main_file","date_created":"2023-03-23T12:49:23Z","file_size":63734746,"file_id":"12745","date_updated":"2023-11-24T11:57:46Z","description":"the main file is missing the bibliography.
