We hypothesized that those effects can prevent blood-sucking insects crossing through waterfalls. This can explain why medium-sized birds risks themselves building their nests behind waterfalls. Secondly, we investigated the 3D kinematics and swimming performance of the black ghost knifefish in response to the complex wake of a free oscillating cylinder. We found that vortex-induced vibrations in bluff bodies create an unsteady flow environment that is more challenging for swimming animals, than K\u0026aacute;rm\u0026aacute;n vortex streets.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"School of Physics, Nonlinear Science \u0026 Mathematics Seminar, Dr. Victor Ortega-Jimenez - Kennesaw State University"}],"uid":"30957","created_gmt":"2019-10-09 14:56:05","changed_gmt":"2019-10-09 14:59:15","author":"Shaun Ashley","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-10-30T13:00:00-04:00","event_time_end":"2019-10-30T14:00:00-04:00","event_time_end_last":"2019-10-30T14:00:00-04:00","gmt_time_start":"2019-10-30 17:00:00","gmt_time_end":"2019-10-30 18:00:00","gmt_time_end_last":"2019-10-30 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"627377":{"id":"627377","type":"image","title":"Dr. Victor Ortega-Jimenez","body":null,"created":"1570633067","gmt_created":"2019-10-09 14:57:47","changed":"1570633067","gmt_changed":"2019-10-09 14:57:47","alt":"","file":{"fid":"238869","name":"Victor Ortega-Jimenez image 10.30.2019.png","image_path":"\/sites\/default\/files\/images\/Victor%20Ortega-Jimenez%20image%2010.30.2019.png","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/Victor%20Ortega-Jimenez%20image%2010.30.2019.png","mime":"image\/png","size":75901,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Victor%20Ortega-Jimenez%20image%2010.30.2019.png?itok=2QrVXOea"}}},"media_ids":["627377"],"groups":[],"categories":[],"keywords":[{"id":"960","name":"physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003Eshaun.ashley@physics.gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
