The Block Copolymer Phase Behavior Database

August 10, 2024
Author(s)
Nathan Rebello, Akash Arora, Hidenobu Mochigase, Tzyy-Shyang Lin, Debra Audus, Bradley Olsen
The Block Copolymer Database (BCDB) is a platform that allows users to search, submit, visualize, benchmark, and download experimental phase measurements and their associated characterization information for di- and multiblock copolymers. To the best of

Coexistence Testing: Comparing Conducted and Radiated Test Results

August 9, 2024
Author(s)
Susanna Mosleh, Nadia Yoza Mitsuishi, Jason Coder, Carl Sunderman
In an era of ubiquitous wireless devices, ensuring their coexistence in shared electromagnetic environments has become increasingly critical. This paper explores the dynamics of coexistence testing and compares two coexistence test environments outlined in

Variation of Site-Specific Glycosylation Profiles of Recombinant Influenza Glycoproteins

August 9, 2024
Author(s)
Zachary Goecker, Meghan Burke Harris, Concepcion Remoroza, Yi Liu, Yuri Mirokhin, Sergey Sheetlin, Dmitrii V. Tchekhovskoi, Xiaoyu (Sara) Yang, Stephen E. Stein
This work presents a detailed determination of site-specific N-glycan distributions of the recombinant influenza glycoproteins hemagglutinin (HA) and neuraminidase. Variation in glycosylation among recombinant glycoproteins is not predictable and can

NIST Special Publication 376, Metric Ruler

August 8, 2024
Author(s)
Elizabeth Benham, Kristen Dill
NIST SP 376, Metric Ruler is an educational tool designed to teach the International System of Units (SI) length measurements. The design includes approximate scales of 300 mm and 30 cm. One edge is graduated in centimeters by alternating solid markings in

Ratchet Loading and Multi-Ensemble Operation in an Optical Lattice Clock

August 8, 2024
Author(s)
Youssef Hassan, Takumi Kobayashi, Tobias Bothwell, Jacob Siegel, Benjamin Hunt, Kyle Beloy, Kurt Gibble, Tanner Grogan, Andrew Ludlow
We demonstrate programmable control over the spatial distribution of ultra-cold atoms confined in an optical lattice. The control is facilitated through a combination of spatial manipulation of the magneto-optical trap and atomic population shelving to a

Report on The Search Futures Workshop at ECIR 2024

August 7, 2024
Author(s)
Leif Azzopardi, Charles Clarke, Paul Kantor, Bhaskar Mitra, Johanne Trippas, Zhaochun Ren, Ian Soboroff
The First Search Futures Workshop, in conjunction with the Fourty-sixth European Conference on Information Retrieval (ECIR) 2024, looked into the future of search to ask questions such as: ˆ How can we harness the power of generative AI to enhance, improve

Low Energy Spiking Neural Network using Ge4Sb6Te7 Phase-Change Memory Synapses

August 6, 2024
Author(s)
Huairuo Zhang, Albert Davydov, Shafin Hamid, Eric Pop, Asir Khan
Spiking neural networks (SNN) with Ge2Sb2Te5 (GST) based phase change memory (PCM) synaptic devices are promising for edge applications. However, from a de-vice standpoint, the performance of such SNN is often con-strained by the abrupt depression

A Review of Community Resilience Indicators Using a Systems Measurement Framework

August 5, 2024
Author(s)
Michael Gerst, Maria Dillard, Emily Walpole, Jarrod Loerzel
As natural disasters have increased in frequency and magnitude, there has been an increasing need to understand what underlying factors are likely to lead to faster recovery and more resilient communities. One way of addressing this need has been to

Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation Revision 1

August 5, 2024
Author(s)
Shahram Orandi, Craig I. Watson, Jennifer Stathakis, John M. Libert, Gregory Fiumara, John Grantham
While contactless fingerprint capture devices stand to provide for many benefits, images from this nascent technology are sufficiently different than traditional contact-collected images thereby warranting the separation of these new contactless

The Proteomics Standards Initiative standardized formats for spectral libraries and fragment ion peak annotations: mzSpecLib and mzPAF

August 5, 2024
Author(s)
Joshua Klein, Henry Lam, Tytus Mak, Wout Bittremieux, Yasset Perez-Riverol, Ralf Gabriels, Jim Shofstahl, Helge Hecht, Pierre-Alain Binz, Shin Kawano, Tim Van Den Bossche, Jeremy Carver, Ben Neely, Luis Mendoza, Tomi Suomi, Tine Claeys, Thomas Payne, Douwe Schulte, Zhi Sun, Nils Hoffmann, Yunping Zhu, Steffen Neumann, Andrew Jones, Nuno Bandeira, Juan Antonio Vizcaino, Eric Deutsch
Mass spectral libraries are collections of reference spectra, usually associated with specific analytes from which the spectra were generated, that are used for further downstream analysis of new spectra. There are many different formats used for encoding

Optical n(p, T_90) measurement suite 3: results at l = 1542 nm

August 3, 2024
Author(s)
Patrick Egan, Yuanchao Yang
Single-isotherm n(p, T90) results are reported for the gases Ar, N2, H2O, and D2O at vacuum wavelength λ = 1542.383(1) nm. The argon and nitrogen isotherms were measured near 303 K; the water isotherms were measured near 373 K. Combined with the two

Measurement-Based Prediction of mmWave Channel Parameters Using Deep Learning and Point Cloud

August 2, 2024
Author(s)
Anuraag Bodi, Raied Caromi, Jian Wang, Jelena Senic, Camillo Gentile, Hang Mi, Bo Ai, Ruisi He
Millimeter-wave (MmWave) channel characteristics are quite different from sub-6 GHz frequency bands. The major differences include higher path loss and sparser multipath components (MPCs), resulting in more significant time-varying characteristics in

Metric Conversion Card

August 2, 2024
Author(s)
Elizabeth Benham, Kristen Dill
NIST SP 365, Metric Conversion Card is a laminated wallet size card includes an 8 cm and 80 mm ruler with approximate unit conversion factors between common International System of Units (SI) and U.S. customary measurement units for length, area, mass

Modeling Spiking Neurons without Spikes

August 2, 2024
Author(s)
Jeff Shainline, Bryce Primavera, Ryan O'Loughlin
While spiking neuromorphic hardware holds promise for efficient implementations of artificial intelligence, the impact has been limited due in part to a lack of learning algorithms that achieve performance superior to conventional deep learning. One
