SentencePiece: A simple and language independent subword tokenizer and detokenizer for Neural Text Processing

Posted by klaurent MIT

Kavli Affiliate: John Richardson | Summary:This paper describes SentencePiece, a language-independent subword tokenizer and detokenizer designed for Neural-based text processing, including Neural Machine Translation. It provides open-source C++ and Python implementations for subword units. While existing subword segmentation tools assume that the input is pre-tokenized into word sequences, SentencePiece can train subword models directly from […]

Absolute and arbitrary orientation of single molecule shapes

Posted by klaurent Caltech

Kavli Affiliate: Paul W. K. Rothemund | Summary:DNA origami is a modular platform for the combination of molecular and colloidal components to create optical, electronic, and biological devices. Integration of such nanoscale devices with microfabricated connectors and circuits is challenging: large numbers of freely diffusing devices must be fixed at desired locations with desired alignment. […]

Quantum signatures in quadratic optomechanics

Posted by klaurent Delft

Kavli Affiliate: Ya Blanter | Summary:We analyze quantum effects occurring in optomechanical systems where the coupling between an optical mode and a mechanical mode is quadratic in displacement (membrane-in-the-middle geometry). We show that it is possible to observe quantum effects in these systems without achieving the single-photon strong coupling regime. We find that zero-point energy […]

Optical Design of PICO, a Concept for a Space Mission to Probe Inflation and Cosmic Origins

Posted by klaurent Cambridge

Kavli Affiliate: Richard Hills | Summary:The Probe of Inflation and Cosmic Origins (PICO) is a probe-class mission concept currently under study by NASA. PICO will probe the physics of the Big Bang and the energy scale of inflation, constrain the sum of neutrino masses, measure the growth of structures in the universe, and constrain its […]

Characterization of atmospheric turbulence for the Large Synoptic Survey Telescope

Posted by klaurent Stanford

Kavli Affiliate: Patricia Burchat | Summary:One of the scientific goals of the Large Synoptic Survey Telescope (LSST) is to measure the evolution of dark energy by measuring subtle distortions of galaxy shapes due to weak gravitational lensing caused by the evolving dark matter distribution. Understanding the point spread function (PSF) for LSST is a crucial […]

Cheeger-Colding-Tian theory for conic Kahler-Einstein metrics

Posted by klaurent Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Gang Tian, Gang Tian, , , | Summary: In this paper is to extend the Cheeger-Colding Theory to the class of conic Kahler-Einstein metrics. This extension provides a technical tool for [LTW] in which we prove a version of the Yau-Tian-Donaldson conjecture for Fano varieties with certain […]

The optical design of the six-meter CCAT-prime and Simons Observatory telescopes

Posted by klaurent Cambridge

Kavli Affiliate: Richard Hills | Summary:A common optical design for a coma-corrected, 6-meter aperture, crossed-Dragone telescope has been adopted for the CCAT-prime telescope of CCAT Observatory, Inc., and for the Large Aperture Telescope of the Simons Observatory. Both are to be built in the high altitude Atacama Desert in Chile for submillimeter and millimeter wavelength […]

CCAT-prime: a novel telescope for submillimeter astronomy

Posted by klaurent Cambridge

Kavli Affiliate: Richard Hills | Summary:The CCAT-prime telescope is a 6-meter aperture, crossed-Dragone telescope, designed for millimeter and sub-millimeter wavelength observations. It will be located at an altitude of 5600 meters, just below the summit of Cerro Chajnantor in the high Atacama region of Chile. The telescope’s unobscured optics deliver a field of view of […]

Observation of a Dirac nodal line in AlB2

Posted by klaurent Tokyo

Kavli Affiliate: Kentaro Hori | Summary:We have performed angle-resolved photoemission spectroscopy of AlB2 which is isostructural to high-temperature superconductor MgB2. Using soft-x-ray photons, we accurately determined the three-dimensional bulk band structure and found a highly anisotropic Dirac-cone band at the K point in the bulk hexagonal Brillouin zone. This band disperses downward on approaching the […]
