Prestrain-induced bandgap tuning in 3D-printed tensegrity-inspired lattice structures

Posted by October 31, 2020Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Kirsti Pajunen, Paolo Celli, Chiara Daraio, , | Summary: In this letter, we provide experimental evidence of bandgap tunability with global prestrain in additively-manufactured tensegrity-inspired lattice structures. These lattices are extremely lightweight and designed to exhibit a nonlinear compressive response that mimics that of a tensegrity structure. […]

Motivations and Preliminary Design for Mid-Air Deployment of a Science Rotorcraft on Mars

Posted by October 13, 2020Caltech

Kavli Affiliate: Morteza Gharib | First 5 Authors: Jeff Delaune, Jacob Izraelevitz, Larry A. Young, William Rapin, Evgeniy Sklyanskiy | Summary: Mid-Air Deployment (MAD) of a rotorcraft during Entry, Descent and Landing (EDL) on Mars eliminates the need to carry a propulsion or airbag landing system. This reduces the total mass inside the aeroshell by […]

Posted by October 12, 2020Stanford

Kavli Affiliate: Eli S. Rykoff | First 5 Authors: LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso, Robert Armstrong, Éric Aubourg | Summary: We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) […]

Static response and Love numbers of Schwarzschild black holes

Posted by October 1, 2020Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Lam Hui, Austin Joyce, Riccardo Penco, Luca Santoni, Adam R. Solomon | Summary: We derive the quadratic action for the physical degrees of freedom of massless spin-0, spin-1, and spin-2 perturbations on a Schwarzschild–(A)dS background in arbitrary dimensions. We then use these results to compute the static […]

Nucleation is More than Critical — A Case Study of the Electroweak Phase Transition in the NMSSM

Posted by September 22, 2020Chicago

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, Yikun Wang | Summary: Electroweak baryogenesis is an attractive mechanism to generate the baryon asymmetry of the Universe via a strong first order electroweak phase transition. We compare the phase transition patterns suggested by […]

Sign of hard X-ray pulsation from the gamma-ray binary system LS 5039

Posted by September 4, 2020Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto, Dmitry Khangulyan, Takahiro Matsumoto | Summary: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data […]

Posted by September 2, 2020Tokyo

Kavli Affiliate: Tom Melia | First 5 Authors: Lukas Graf, Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama | Summary: We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation […]

Development of a Low-noise Front-end ASIC for CdTe Detectors

Posted by September 1, 2020Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Tadashi Orita, Shin’ichiro Takeda, Shin Watanabe, Hirokazu Ikeda | Summary: We present our latest ASIC, which is used for the readout of Cadmium Telluride double-sided strip detectors (CdTe DSDs) and high spectroscopic imaging. It is implemented in a 0.35 um CMOS technology (X-Fab XH035), consists […]

Phase effects from strong gravitational lensing of gravitational waves

Posted by August 28, 2020Chicago

Kavli Affiliate: Robert M. Wald | First 5 Authors: Jose María Ezquiaga, Daniel E. Holz, Wayne Hu, Macarena Lagos, Robert M. Wald | Summary: Assessing the probability that two or more gravitational waves (GWs) are lensed images of the same source requires an understanding of the image properties, including their relative phase shifts in strong […]
