CompilerGym: Robust, Performant Compiler Optimization Environments for AI Research

Kavli Affiliate: Jia Liu | First 5 Authors: Chris Cummins, Bram Wasti, Jiadong Guo, Brandon Cui, Jason Ansel | Summary: Interest in applying Artificial Intelligence (AI) techniques to compiler optimizations is increasing rapidly, but compiler research has a high entry barrier. Unlike in other domains, compiler and AI researchers do not have access to the […]

Imaging reconfigurable molecular concentration on a graphene field-effect transistor

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Franklin Liou, Hsin-Zon Tsai, Andrew S. Aikawa, Kyler C. Natividad, Eric Tang | Summary: The spatial arrangement of adsorbates deposited onto a clean surface in vacuum typically cannot be reversibly tuned. Here we use scanning tunneling microscopy to demonstrate that molecules deposited onto graphene field-effect transistors […]

The stellar mass versus stellar metallicity relation of star-forming galaxies at $1.6le zle3.0$ and implications for the evolution of the $α$-enhancement

Kavli Affiliate: John D. Silverman | First 5 Authors: Daichi Kashino, Simon J. Lilly, Alvio Renzini, Emanuele Daddi, Giovanni Zamorani | Summary: We measure the relationship between stellar mass and stellar metallicity, the stellar mass–metallicity relation (MZR), for 1336 star-forming galaxies at $1.6le zle3.0$ (<z>=2.2) using rest-frame far-ultraviolet spectra from the zCOSMOS-deep survey. High signal-to-noise […]

Discretization of Annular-Ring Diffraction Pattern for Large-Scale Photonics Beamforming

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Artsroun Darbinian, Ali Hajimiri, | Summary: A solid-state active beamformer based on the annular-ring diffraction pattern is proposed for an integrated photonic platform. Such a circularly symmetric annular-ring aperture achieves radiating element limited FOV. Furthermore, it is demonstrated that a multi-annular-ring aperture with […]

Farpoint: A High-Resolution Cosmology Simulation at the Gigaparsec Scale

Kavli Affiliate: Salman Habib | First 5 Authors: Nicholas Frontiere, Katrin Heitmann, Esteban Rangel, Patricia Larsen, Adrian Pope | Summary: In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a volume of (1000$h^{-1}$Mpc)$^3$ and evolves close to two trillion particles, […]

Can Cooling and Heating Functions be Modeled with Homogeneous Radiation Fields?

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: David Robinson, Camille Avestruz, Nickolay Y. Gnedin, , | Summary: Cooling and heating functions describe how radiative processes impact the thermal state of a gas as a function of its temperature and other physical properties. In a most general case the functions depend on the detailed […]

Blázquez-Salcedo-Knoll-Radu Wormholes Are Not Solutions to the Einstein-Dirac-Maxwell Equations

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, Robert J. Weinbaum, | Summary: Recently, Bl’azquez-Salcedo, Knoll, and Radu (BSKR) have given a class of static, spherically symmetric, traversable wormhole spacetimes with Dirac and Maxwell fields. The BSKR wormholes are obtained by joining a classical solution to […]

Third Data Release of the Hyper Suprime-Cam Subaru Strategic Program

Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Hiroaki Aihara, Yusra AlSayyad, Makoto Ando, Robert Armstrong, James Bosch | Summary: The paper presents the third data release of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with […]
