Kavli Affiliate: Wei Gao | First 5 Authors: Meng-Zhang Qian, Zheng Ai, Teng Zhang, Wei Gao, | Summary: Margin has played an important role on the design and analysis of learning algorithms during the past years, mostly working with the maximization of the minimum margin. Recent years have witnessed the increasing empirical studies on the […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xiaoqing Fan, Ge Li, Dingquan Li, Yurui Ren, Wei Gao | Summary: Point cloud compression plays a crucial role in reducing the huge cost of data storage and transmission. However, distortions can be introduced into the decompressed point clouds due to quantization. In this paper, we propose […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Alexander Madurowicz, Bruce Macintosh, , , | Summary: The prospect of combining integral field spectroscopy with the solar gravitational lens (SGL) to spectrally and spatially resolve the surfaces and atmospheres of extrasolar planets is investigated. The properties of hyperbolic orbits visiting the focal region of the SGL […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Melanie Clarke, Sachin Shenoy, William Vacca, Simon Coude | Summary: We describe the data processing of the Survey on extragALactic magnetiSm with SOFIA (SALSA Legacy Program). This first data release presents 33% (51.34h out of 155.7h, including overheads) of the total awarded time taken […]
Kavli Affiliate: George Ricker | First 5 Authors: Luisa Maria Serrano, Davide Gandolfi, Alexander J. Mustill, Oscar Barragán, Judith Korth | Summary: It is commonly accepted that exoplanets with orbital periods shorter than 1 day, also known as ultra-short period (USP) planets, formed further out within their natal protoplanetary disk, before migrating to their current-day […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Iosif Bena, Emil J. Martinec, Samir D. Mathur, Nicholas P. Warner, | Summary: The black-hole information paradox provides one of the sharpest foci for the conflict between quantum mechanics and general relativity and has become the proving-ground of would-be theories of quantum gravity. String theory has […]
Kavli Affiliate: Richard Partridge | First 5 Authors: Jonathan S. Wilson, Hanno Meyer zu Theenhausen, Belina von Krosigk, Elham Azadbakht, Ray Bunker | Summary: The SuperCDMS SNOLAB dark matter search experiment aims to be sensitive to energy depositions down to O(1 eV). This imposes requirements on the resolution, signal efficiency, and noise rejection of the […]

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We present the first nonlinear lattice simulation of an axion field coupled to a U(1) gauge field during inflation. We use it to fully characterize the statistics of the primordial curvature perturbation {zeta}. We find high-order […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: If gauge fields are coupled to an axion field during inflation, they lead to unique observational signatures within the reach of next generation experiments. However, this system often shows strong backreaction effects, invalidating the standard perturbation […]
