Safeguarding International Science: Research Security Framework

August 31, 2023
Author(s)
Gregory F. Strouse, Claire M. Saundry, Timothy Wood, Philip Bennett, Mary Bedner
The U.S. science and research ecosystem retains its leadership by actively engaging with the global community through the conduct of mutually beneficial collaborative research and the welcoming of international scientists. Coupled with that, the national

A multipathway phosphopeptide standard for rapid phosphoproteomics assay development

August 30, 2023
Author(s)
Brian Searle, Allis Chien, Antonius Koller, David Hawke, Anthony Herren, Jenny Kim, Kimberly Lee, Ryan Leib, Alissa Nelson, Jian Min Ren, Paul Stemmer, Yiying Zhu, Ben Neely, Bhavin Patel
Recent advances in methodology have made phosphopeptide analysis a tractable problem for many proteomics researchers. There are now a wide variety of robust and accessible enrichment strategies to generate phosphoproteomes while free or inexpensive

Determining Site-Specific Glycan Profiles of Recombinant SARS-CoV-2 Spike Proteins from Multiple Sources

August 30, 2023
Author(s)
Meghan Burke Harris, Yi Liu, Concepcion Remoroza, Yuri Mirokhin, Sergey Sheetlin, Dmitrii V. Tchekhovskoi, Guanghui Wang, Xiaoyu (Sara) Yang, Stephen E. Stein
Glycopeptide Abundance Distribution Spectra (GADS) were recently introduced as a means of representing, storing and comparing glycan profiles of intact glycopeptides. Here, using that representation, an extensive analysis is made of multiple commercial

Wireless Channel Characterization for UWB Communication in Capsule Endoscopy

August 30, 2023
Author(s)
Katjana Ladic, Kamran Sayrafian, Dina Simunic, Kamya Yazdandoost
Since its invention in the early 1990s the technology behind capsule endoscopy has been making rapid progress. The emergence of high-resolution miniature video cameras along with other microsensor technology have increased the data rate and power

Dynamic Regret of Randomized Online Service Caching in Edge Computing

August 29, 2023
Author(s)
Siqi Fan, I-Hong Hou, Van Sy Mai
This paper studies an online service caching problem, where an edge server, equipped with a prediction window of future service request arrivals, needs to decide which services to host locally subject to limited storage capacity. The edge server aims to

Quantifying the Effect of Guest Binding on Host Environment

August 29, 2023
Author(s)
Angela Stelson, Zack Fishman, Jacob Pawlik, Gosia Musial, Jim Booth, Chris Long, Kathleen Schwarz, Nate Orloff, Hugh Ryan, Angela Grommet, Jonathan Nitschke, Felix Rizzuto
The environment around a host-guest complex is defined by of intermolecular interactions between solvent molecules and counter ions. These interactions govern both the solubility of these complexes and the rates of reactions confined within them11. Such

Sub-GHz Resolution Line-by-Line Pulse Shaper for Driving Josephson Junctions

August 29, 2023
Author(s)
Dahyeon Lee, Takuma Nakamura, Andrew Metcalf, Nathan Flowers-Jacobs, Anna Fox, Paul Dresselhaus, Franklyn Quinlan
We demonstrate a sub-GHz resolution, fully programmable Fourier-domain pulse shaper capable of generating arbitrary optical pulse patterns. This high resolution allows line-by-line pulse shaping of a 1 GHz comb with a span as large as 1 THz, which

Adaptive Channel-State-Information Feedback in Integrated Sensing and Communication Systems

August 28, 2023
Author(s)
Neeraj Varshney, Samuel Berweger, Jack Chuang, Steve Blandino, Jian Wang, Neha Pazare, Camillo Gentile, Nada T. Golmie
Efficient design of integrated sensing and communication systems can minimize signaling overhead by reducing the size and/or rate of feedback in reporting channel state information (CSI). To minimize the signaling overhead when performing sensing

Quantum Spin Ice Response to a Magnetic Field in the Dipole-Octupole Pyrochlore Ce2Zr2O7

August 28, 2023
Author(s)
E. Smith, J. Dudemaine, B. Placke, R. Schafer, D. Yahne, T. DeLazzer, A. Fitterman, J. Beare, Jonathan N. Gaudet, C.R.C. Buhariwalla, Andrey Podlesnyak, Guangyong Xu, J. Clancy, R. Movshovich, G. Luke, K. Ross, R. Moessner, O. Benton, A. Bianchi, B. Gaulin
The pyrochlore magnet Ce2Zr2O7 has attracted much attention as a quantum spin ice candidate whose novelty derives in part from the dipolar-octupolar nature of the Ce3+ pseudospin-1/2 degrees of freedom it possesses. We report heat capacity measurements on

Compressed liquid density and speed of sound measurements and correlation of the binary mixture Carbon dioxide (CO2) + 1,1-difluoroethene (R1132a)} at temperatures from 220 K to 350 K

August 25, 2023
Author(s)
Davide Menegazzo, Aaron Rowane, Laura Fedele, Sergio Bobbo, Giulia Lombardo, Mark O. McLinden
The blend of carbon dioxide and R1132a has been suggested as feasible alternative to R23 in low-temperature devices. In this work, we present a new set of experimental data for compressed-liquid density, vapour density and compressed-liquid speed of sound

Investigating electromagnetically induced transparency spectral lineshape distortion due to non-uniform fields in Rydberg-atom electrometry

August 25, 2023
Author(s)
Drew Rotunno, Samuel Berweger, Nik Prajapati, Aly Artusio-Glimpse, MATTHEW SIMONS, chris holloway, Amy Robinson
We investigate the effects of spatially non-uniform radio-frequency electric (E) field amplitudes on the spectral line shapes of electromagnetically induced transparency (EIT) signals in Rydberg atomic systems used in electrometry (i.e., the metrology of E
