Dr Cencheng Shen, Applied Economics and Statistics, University of Delaware Dr Cencheng Shen, Applied Economics and Statistics, University of DelawareEwing 336 Conference RoomTitle: Dependency Discovery via Multiscale Graph Correlation <br><br> Abstract: Determining how certain properties are related to other properties is fundamental to scientific discovery; further investigations into the geometry of the relationship and future predictions are warranted only if two properties are significantly related. To better discover any type of relationship underlying paired sample data, we introduce the multiscale graph correlation (MGC), which combines distance correlation, the locality principle, and smoothed maximum to yield a new and powerful dependency measure. <br><br> We prove that MGC is consistent for testing independence, enjoys a number of desirable theoretical properties, exhibits empirical power advantages against a wide range of nonlinear and high-dimensional dependencies, and can be efficiently implemented and utilized for real data exploration.11/12/2018 4:15:00 PM11/12/2018 5:15:00 PMFalse

Dr. Enkelaida Lushi, Flatiron InstituteDr. Enkelaida Lushi, Flatiron InstituteEwing 336 Conference RoomTitle: Nonlinear concentration patterns and bands in chemotactic active suspensions <br><br> Abstract: In suspensions of microorganisms, pattern formation can arise from the interplay of chemotaxis and the fluid flows collectively-generated by the organisms themselves. Here we investigate the resulting pattern formation in square and elongated domains when the chemo-attractant dynamics is fully coupled to the fluid flows and swimmer motion. Analyses reveal an aggregative instability due to chemotaxis, independent of swimmer shape and type, and a hydrodynamic instability for “pusher” swimmers. Simulations reveal a critical length scale of the swimmer aggregates and this feature e can be utilized to stabilize swimmer concentration patterns into quasi-one-dimensional bands by varying the domain size. These concentration bands transition to traveling pulses under an external chemo-attractant gradient, as observed in experiments with chemotactic bacteria. 11/1/2018 7:30:00 PM11/1/2018 8:30:00 PMFalse
