With proper physical understanding, the diffusion coefficient gives information about the size, oligomerization, and local environment.

Getting this right\u0026nbsp;also gives us a nice way to quantify correlated motions in both simulations and experiments. Meanwhile, simulations are typically performed in periodic boundary conditions.\u0026nbsp;We find that these conditions can cause typical simulations to underestimate experiment by a factor of 3 or more.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Diffusion, correlated motions and periodic boundary conditions in lipid membranes"}],"uid":"30957","created_gmt":"2017-04-04 20:19:53","changed_gmt":"2017-04-13 21:12:08","author":"Shaun Ashley","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-04-18T16:00:00-04:00","event_time_end":"2017-04-18T17:00:00-04:00","event_time_end_last":"2017-04-18T17:00:00-04:00","gmt_time_start":"2017-04-18 20:00:00","gmt_time_end":"2017-04-18 21:00:00","gmt_time_end_last":"2017-04-18 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"960","name":"physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78751","name":"Undergraduate students"},{"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":""}}}
