Workshop on Imaging Biomarkers

Welcome to the Fifth Annual CMROI Workshop on Imaging Biomarkers to be held Thursday, March 22nd, 2018 at the Biomedical Research Building II/III of the Perelman School of Medicine at the University of Pennsylvania…

Condensed Matter Seminar: "Geometry and mechanics of feet and fins"

Mahesh M. Bandi (Okinawa Institute of Science and Technology Graduate University)

The stiffness of propulsive appendages, such as feet and fins, is important in locomotory function. In this talk, I show that curvature-induced stiffness is the common principle underlying the stiffness of both…

High Energy Theory Seminar: "Discrete Superconformal Matter"

Paul Oehlmann (Virginia Tech)

We construct a novel type of (2,0) discrete charged superconformal matter coupled to 6d supergravity using F-theory. For this, we consider smooth genus-one fibered and compact Calabi-Yau threefolds quotiented by a…

Astro Seminar: "Insights Into Dark Matter From the Stellar Halos of Galaxies"

Robyn Sanderson (Caltech)

Cosmological simulations can now make specific and detailed predictions for the shapes, masses, and substructure fractions in galactic dark matter halos that depend on the dark matter model assumed. Comparing these…

Primakoff Lecture: "Metamaterials and Topological Mechanics"

Tom Lubensky (University of Pennsylvania)

Metamaterials are materials engineered to have a property or properties not found in nature, such as a negative optical index of refraction, one-way light or vibration waves, or exotic elastic behavior.  Advances in…

Astro Seminar: "The Chaotic Life Cycles of Planetary Systems"

Daniel Tamayo (University of Toronto)

The past two decades have seen the discovery of thousands of new planetary systems in our galactic neighborhood, many of which look drastically different from our own. However, despite this remarkable observational…

HET & HEE Joint Seminar: "Unification from Scattering Amplitudes"

Cliff Cheung (Caltech)

Scattering amplitudes are fundamental observables that encode the dynamics of interacting particles. In this talk, I describe how to systematically construct these objects without reference to a Lagrangian or an…

High Energy Theory Seminar: "Coarse-Graining Holographic Entanglement"

Netta Engelhardt (Princeton)

Astro Seminar: "Cosmic Microwave Backlight: Illuminating Large-Scale Structure with the Universe's Oldest Photons"

Colin Hill (IAS/Flatiron Institute)

Studies of the cosmic microwave background (CMB) radiation have driven the current era of precision cosmology.  The tightest cosmological constraints to date have been derived from the primary CMB anisotropies, which…

Condensed Matter Seminar: "Structure and Topology of Band Structures in the 1651 Magnetic Space Groups"

Ashvin Vishwanath (Harvard University)

We describe a powerful theoretical approach to studying electronic band structures, which associates them with elements of a vector space. The set of consistent band structures in a space group can then be expanded…
