Kavli Affiliate: Angela J. Yu | First 5 Authors: Sheeraz Ahmad, Angela J. Yu, , , | Summary: Sensory inference under conditions of uncertainty is a major problem in both machine learning and computational neuroscience. An important but poorly understood aspect of sensory processing is the role of active sensing. Here, we present a Bayes-optimal […]
Kavli Affiliate: Catherine E. Grant | First 5 Authors: Catherine E. Grant, Matteo Guainazzi, Lorenzo Natalucci, Jukka Nevalainen, Paul P. Plucinsky | Summary: We present the main results of the 8th International Astronomical Consortium for High Energy Calibration (IACHEC) meeting, held in Theddingworth, Leicestershire, between March 25 and 28, 2013. Over 50 scientists directly involved […]
Kavli Affiliate: Emil Martinec | First 5 Authors: Peter Adshead, Emil Martinec, Mark Wyman, , | Summary: Chromo-Natural Inflation is the first worked example of a model of inflation in which slow-roll inflation is achieved by "magnetic drift" as opposed to Hubble friction. In this work, we give an account of the perturbations at linear […]
Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Abram L. Falk, Bob B. Buckley, Greg Calusine, William F. Koehl, Viatcheslav V. Dobrovitski | Summary: Crystal defects can confine isolated electronic spins and are promising candidates for solid-state quantum information. Alongside research focusing on nitrogen vacancy centers in diamond, an alternative strategy seeks to identify […]
Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Jannis Bielefeld, W. L. Kimmy Wu, Robert R. Caldwell, Olivier Dore, | Summary: A phenomenological model of dark energy that tracks the baryonic and cold dark matter at early times but resembles a cosmological constant at late times is explored. In the transition between these […]

Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: John Rutherford, Daniel Dewey, Enectali Figueroa-Feliciano, Sarah N. T. Heine, Fabienne A. Bastien | Summary: We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the […]
Kavli Affiliate: Kentaro Hori | First 5 Authors: Francesco Benini, Richard Eager, Kentaro Hori, Yuji Tachikawa, | Summary: We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is expressed as a sum over residues of a meromorphic function whose argument […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Starting with a choice of a gauge group in four dimensions, there is often freedom in the choice of magnetic and dyonic line operators. Different consistent choices of these operators correspond to distinct physical theories, with the same correlation functions […]
