Department Colloquium:"The Maps Inside Your Head"
Vijay Balasubramanian (UPenn) hosted by: Joe Kroll
How do our brains make sense of a complex and unpredictable world? In this talk, I will discuss a physicist's approach to the neural topography of information processing in the brain. First I will review the brain's…
Astro Seminar: "The New Ly-alpha Power Spectrum Measurements and constraints on WDM"
Vid Irsic (University of Washington)
With the X-Shooter XQ-100 Legacy survey, 100 QSO measurements at intermediate resolutions were available to measure the Lyman-alpha power spectrum in the similar redshift range to SDSS (z=3 - 4.2), but to smaller…
Dissertation Defense: Toric Elliptic Fibrations Over Hirzebruchs
Prashant Subbarao (UPenn)
Experimental Particle Physics: "Search for Supersymmetry in Events with Four or More Leptons at ATLAS "
Matthew Klein (Columbia University)
Math-Bio seminar: "Controlling the rate of false discoveries in tandem mass spectrum identifications"
Uri Keich, University of Sydney
A typical shotgun proteomics experiment produces thousands of tandem mass spectra, each of which can be tentatively assigned a corresponding peptide by using a database search procedure that looks for a peptide-…
High Energy Seminar: "Shaving off Black Hole Soft Hair"
Massimo Porrati (New York University)
After recalling a definition of a black hole "hair" we explain why the only interesting hairs are those that are also remnants. Next, we will examine a recent proposal by Hawking, Perry and Strominger, who suggest…
Where Did Half the Light in the Universe Go?
Professor Mark Devlin (UPenn)
Prof. Mark Devlin will be presenting a public talk as part of the Museum’s popular Night Skies program.
The evening also includes Planetarium shows and an opportunity to look through the rooftop…
Condensed Matter seminar: "Putting Patterns on Spheres: Pollen Grains and Cholesteric Liquid Crystal Shells"
Max Lavrentovich, University of Pennsylvania
Insect egg shells, mite carapaces, pollen grain surfaces, and many other biological materials exhibit intricate surface patterns including stripes, spikes, pores, and ridges.
Math-Bio seminar: "Changes in local chromatin structure during homology search: effects of local contacts on search time"
Assaf Amitai, M.I.T.
Double-strand break (DSB) repair by homologous recombination (HR) requires an efficient and timely search for a homologous template. We developed a statistical method of analysis based on single-particle…
