Extracting Mathematical Concepts from Text

October 12, 2022
Author(s)
Jacob Collard, Valeria de Paiva, Brendan Fong, Eswaran Subrahmanian
We investigate some different systems for extracting mathematical entities from texts in the mathematical field of category theory, as a first step for constructing a mathematical knowledge graph. We consider four different term extractors and compare

Improving Support-Minors rank attacks: applications to GeMSS and Rainbow

October 12, 2022
Author(s)
John Bayron Baena Giraldo, Pierre Briaud, Daniel Cabarcas Jaramillo, Ray Perlner, Daniel Smith-Tone, Javier Verbel
The Support-Minors (SM) method has opened new routes to attack multivariate schemes with rank properties that were previously impossible to exploit, as shown by the recent attacks of [9, 40] on the Round 3 NIST candidates GeMSS and Rainbow respectively. In

On the "intrinsic" breakdown of thick gate oxide

October 12, 2022
Author(s)
Kin (Charles) Cheung
Thick gate oxide breakdown mechanism becomes an important topic again due to the rising demand of power electronics. The failure of the percolation model in explaining the observed Weibull shape factor of thick oxide breakdown distribution seriously

Bitemark Analysis Reference List

October 11, 2022
Author(s)
Kelly Sauerwein
This report provides supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. Publicly available resources relating to bitemark analysis were collected to assist in the review of the scientific foundations of bitemark

CSAFE Bitemark Thinkshop Report

October 11, 2022
Author(s)
NFN CSAFE, Kelly Sauerwein
This is supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. NIST asked the Center for Statistics and Applications in Forensic Evidence (CSAFE), a NIST Forensic Science Center of Excellence, to organize a Bitemark

Standards and Guidelines in Forensic Odontology

Author(s)
Karen Reczek
This report provides supplemental information to NISTIR 8352 Bitemark Analysis: A NIST Scientific Foundation Review. Standards and guidelines from the American Dental Association (ADA) and the International Organization of Standardization (ISO) as well as

Unravelled and Glassy Magnetism in PbFe 1/2 Nb 1/2 O 3 - (2) Neutron Scattering

October 11, 2022
Author(s)
C. Stock, B. Roessli, Peter M. Gehring, Jose Rodriguez Rivera, N. Giles-Donovan, S. Cochran, Guangyong Xu, P. Manuel, M. J. Gutmann, William D. Ratcliff, T. Fennell, Y. Su, X. Li, H. Luo
We apply neutron scattering to investigate the magnetism in the relaxor ferroelectric PbFe 1/2Nb 1/2O 3 (PFN). Similar to the lack of spatially long-range ferroelectric order in prototypical relaxors like Pb(Mg,Zn) 1/3Nb 2/3O 3 (PMN and PZN), spatially

Bi 12 O 17 Cl 2 with a Sextuple Bi-O Layer Composed of Rock-Salt and Fluorite Units and its Structural Conversion through Fluorination to Enhance Photocatalytic Activity

October 10, 2022
Author(s)
Daichi Kato, Osamu Tomita, Ryky Nelson, Maria A. Kirsanova, Richard Dronskowski, Hajime Suzuki, Chengchao Zhong, Cedric Tassel, Kohdai Ishida, Yosuke Matsuzaki, Craig Brown, Koji Fujita, Kotaro Fujii, Masatomo Yashima, Yoji Kobayashi, Akinori Saeki, Itaru Oikawa, Hitoshi Takamura, Ryu Abe, Hiroshi Kageyama, Tatiana E. Gorelik, Artem M. Abakumov
Layered bismuth oxyhalides with bilayered (Bi 2O 2) fluorite slabs are promising visible-light photocatalysts because of the ability to control the valence band levels. Here we show that a structurally uncharacterized Bi 12O 17Cl 2, which has been

Glycosylation and the global virome

October 10, 2022
Author(s)
Cassandra Pegg, Benjamin Schulz, Ben Neely, Gregory Albery, Colin Carlson
The sugars that coat the outsides of viruses and host cells are key to successful disease transmission, but they remain understudied compared to other molecular features. Understanding the comparative zoology of glycosylation - and harnessing it for

Demonstration of Superconducting Optoelectronic Single-Photon Synapses

October 6, 2022
Author(s)
Saeed Khan, Bryce Primavera, Jeff Chiles, Adam McCaughan, Sonia Buckley, Alexander Tait, Adriana Lita, John Biesecker, Anna Fox, David Olaya, Richard Mirin, Sae Woo Nam, Jeff Shainline
Superconducting optoelectronic hardware is being explored as a path towards artificial spiking neural networks with unprecedented scales of complexity and computational ability. Such hardware combines integrated-photonic components for few-photon, light
