Kavli Affiliate: Alan Levine | First 5 Authors: Saul Rappaport, Roberto Sanchis-Ojeda, Leslie A. Rogers, Alan Levine, Joshua N. Winn | Summary: The requirement that a planet must orbit outside of its Roche limit gives a lower limit on the planet’s mean density. The minimum density depends almost entirely on the orbital period and is […]
Kavli Affiliate: Mikhail G. Shapiro | First 5 Authors: Adam H. Marblestone, Bradley M. Zamft, Yael G. Maguire, Mikhail G. Shapiro, Thaddeus R. Cybulski | Summary: Simultaneously measuring the activities of all neurons in a mammalian brain at millisecond resolution is a challenge beyond the limits of existing techniques in neuroscience. Entirely new approaches may […]
Kavli Affiliate: Erotokritos Katsavounidis | First 5 Authors: Rahul Biswas, Lindy Blackburn, Junwei Cao, Reed Essick, Kari Alison Hodge | Summary: The sensitivity of searches for astrophysical transients in data from the LIGO is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, P. A. R. Ade, N. Aghanim, C. Armitage-Caplan, M. Arnaud | Summary: We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating […]
Kavli Affiliate: Mark Bowick | First 5 Authors: Mark Bowick, Rastko Sknepnek, , , | Summary: The interplay between geometry, topology and order can lead to geometric frustration that profoundly affects the shape and structure of a curved surface. In this commentary we show how frustration in this context can result in the faceting of […]
Kavli Affiliate: Toshitake Kohno | First 5 Authors: Toshitake Kohno, Andrei Pajitnov, , , | Summary: Let X be a finite CW-complex, denote its fundamental group by G. Let R be an n-dimensional complex repesentation of G. Any element A of the first cohomology group of X with complex coefficients gives rise to the exponential […]
