 +The BlueCross BlueShield team researched emergency department overutilization by analyzing claims information supplied by BCBS. By further analyzing the demographics and the reasons for visiting the emergency department, we were able to better understand the source of emergency department overutilization. Claims that were labeled “preventable” and could be attended to in non-emergency department settings were of particular interest to our research.
-Undercover Symmetry 
-Spend some time with the images shown, which, according to the usual classification, have exactly the same symmetry type. Something seems different about the right-hand image: Why do the yellow/pink bowties seem to have mirror symmetry, which are not symmetries of the pattern as a whole? Why are they set at such strange angles relative to the orientation of the grid of red dots? These strange features led me to discover new types of symmetry in wallpaper patterns, with unexpected connections to such things as eigenvalues of a Laplacian and the length spectra of orbifolds.

Upcoming Colloquium

Mathematics Practicum and Computer Science Interim Presentations

Thursday, March 1, 2:30 in RNS 310

The BlueCross BlueShield team researched emergency department overutilization by analyzing claims information supplied by BCBS. By further analyzing the demographics and the reasons for visiting the emergency department, we were able to better understand the source of emergency department overutilization. Claims that were labeled “preventable” and could be attended to in non-emergency department settings were of particular interest to our research.
