Defining Pathway Assembly and Exploring its Applications

Kavli Affiliate: Stuart Marshall | First 5 Authors: Alastair Murray, Stuart Marshall, Leroy Cronin, , | Summary: How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based […]

Value of the Cosmological Constant in Emergent Quantum Gravity

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: It is suggested that the exact value of the cosmological constant could be derived from first principles, based on entanglement of the Standard Model field vacuum with emergent holographic quantum geometry. For the observed value of the cosmological constant, geometrical […]

A 1.6:1 Bandwidth Two-Layer Antireflection Structure for Silicon Matched to the 190-310 GHz Atmospheric Window

Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Fabien Defrance, Cecile Jung-Kubiak, Jack Sayers, Jake Connors, Clare deYoung | Summary: Although high-resistivity, low-loss silicon is an excellent material for THz transmission optics, its high refractive index necessitates antireflection treatment. We fabricated a wide-bandwidth, two-layer antireflection treatment by cutting subwavelength structures into the silicon surface […]

On the Gas Content and Efficiency of AGN Feedback in Low-redshift Quasars

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Jinyi Shangguan, Luis C. Ho, Yanxia Xie, , | Summary: The interstellar medium is crucial to understanding the physics of active galaxies and the coevolution between supermassive black holes and their host galaxies. However, direct gas measurements are limited by sensitivity and other uncertainties. Dust provides an […]

From actinides to zinc: Using the full abundance pattern of the brightest star in Reticulum II to distinguish between different r-process sites

Kavli Affiliate: Alexander Ji | First 5 Authors: Alexander P. Ji, Anna Frebel, , , | Summary: The ultra-faint dwarf galaxy Reticulum II was enriched by a rare and prolific r-process event, such as a neutron star merger. To investigate the nature of this event, we present high-resolution Magellan/MIKE spectroscopy of the brightest star in […]

Yield precursor dislocation avalanches in small crystals: the irreversibility transition

Kavli Affiliate: Julia R. Greer | First 5 Authors: Xiaoyue Ni, Haolu Zhang, Danilo B. Liarte, Louis W. McFaul, Karin A. Dahmen | Summary: The transition from elastic to plastic deformation in crystalline metals shares history dependence and scale-invariant avalanche signature with other non-equilibrium systems under external loading: dilute colloidal suspensions, plastically-deformed amorphous solids, granular […]

On-Orbit Performance of the Helioseismic and Magnetic Imager Instrument onboard the Solar Dynamics Observatory

Kavli Affiliate: Philip H. Scherrer | First 5 Authors: J. Todd Hoeksema, Charles S. Baldner, Rock I. Bush, Jesper Schou, Philip H. Scherrer | Summary: The Helioseismic and Magnetic Imager (HMI) instrument is a major component of NASA’s Solar Dynamics Observatory (SDO) spacecraft. Since beginning normal science operations on 1 May 2010, HMI has operated […]

Compressive Light Field Reconstructions using Deep Learning

Kavli Affiliate: Alyosha Molnar | First 5 Authors: Mayank Gupta, Arjun Jauhari, Kuldeep Kulkarni, Suren Jayasuriya, Alyosha Molnar | Summary: Light field imaging is limited in its computational processing demands of high sampling for both spatial and angular dimensions. Single-shot light field cameras sacrifice spatial resolution to sample angular viewpoints, typically by multiplexing incoming rays […]
