A General Lattice and Basis Formalism Enabling Efficient and Discretized Exploration of Crystallographic Phase Space

Posted by klaurent Berkeley

Kavli Affiliate: Kristin Persson | First 5 Authors: David Mrdjenovich, Kristin Persson, , , | Summary: Three-dimensional lattices are fundamental to solid-state physics. The description of a lattice with an atomic basis constitutes the necessary information to predict solid phase properties and evolution. Here, we present a new algorithm for systematically exploring crystallographic phase space. […]

Understanding the effects of charge diffusion in next-generation soft X-ray imagers

Posted by klaurent MIT

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Eric D. Miller, Gregory Y. Prigozhin, Beverly J. LaMarr, Marshall W. Bautz, Richard F. Foster | Summary: To take advantage of high-resolution optics sensitive to a broad energy range, future X-ray imaging instruments will require thick detectors with small pixels. This pixel aspect ratio affects spectral […]

TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf

Posted by klaurent MIT

Kavli Affiliate: George Ricker | First 5 Authors: Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson, Andrea Bonfanti, Vardan Adibekyan | Summary: We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ($T = 8.5$ mag), high proper motion ($sim,200$ mas yr$^{-1}$), […]

A Hybrid Model of Classification and Generation for Spatial Relation Extraction

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang Peifeng Li, Qiaoming Zhu, , , | Summary: Extracting spatial relations from texts is a fundamental task for natural language understanding and previous studies only regard it as a classification task, ignoring those spatial relations with null roles due to their poor information. To address […]

Spectral extremal graphs for disjoint cliques

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: The $kK_{r+1}$ is the union of $k$ disjoint copies of $(r+1)$-clique. Moon [Canad. J. Math. 20 (1968) 95–102] and Simonovits [Theory of Graphs (Proc. colloq., Tihany, 1996)] independently showed that if $n$ is sufficiently large, then $K_{k-1}vee T_{n-k+1,r}$ […]

One-Electron Quantum Cyclotron as a Milli-eV Dark-Photon Detector

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Roni Harnik, Thomas G. Myers | Summary: We propose using trapped electrons as high-$Q$ resonators for detecting meV dark photon dark matter. When the rest energy of the dark photon matches the energy splitting of the two lowest cyclotron […]

In silico discovery of repetitive elements as key sequence determinants of 3D genome folding

Posted by klaurent UCSF

Kavli Affiliate: Michael Keiser | Authors: Laura M Gunsalus, Michael J. Keiser and Katherine S Pollard | Summary: Abstract Natural and experimental genetic variants can modify DNA loops and insulating boundaries to tune transcription, but it is unknown how sequence perturbations affect chromatin organization genome-wide. We developed an in silico deep-learning strategy to quantify the […]
