Constraints on Gaussian Error Channels and Measurements for Quantum Communication

April 10, 2023

Author(s)

Alexander T. Kwiatkowski, Ezad Shojaee, Sristy Agrawal, Akira Kyle, Curtis Rau, Scott Glancy, Emanuel Knill

Joint Gaussian measurements of two quantum systems are important for quantum communication between remote parties and are often used in continuous-variable teleportation or entanglement-swapping protocols. Many of the errors in real-world implementations

Impactor Collection Efficiencies Can Modify the Uncertainty of Multiply Charged Particles in Optical Extinction Measurements

April 10, 2023

Author(s)

Chunning Mao, Akua Asa-Awuku, Christopher D. Zangmeister, Jamie Weaver, James Radney

The complex distribution of particle charge states resulting from neutralization processes by radioactive or soft X-ray charge neutralizers is a well-documented problem in aerosol science. Here, we demonstrate that non-idealities in the collection

Sequence-based allelic variations and frequencies for 22 autosomal STR loci in the Lebanese population

April 10, 2023

Author(s)

Sarah Riman, Mirna Ghemrawi, Lisa Borsuk, Rami Mahfouz, Susan Walsh, Peter Vallone

This is the first study that characterizes the sequence-based allelic variations of 22 autosomal Short Tandem Repeat (aSTR) loci in a population dataset collected from Lebanon. Genomic DNA extracts from 195 unrelated Lebanese individuals were amplified

Temperature Distribution in TaOx Resistive Switching Devices Assessed In Operando by Scanning Thermal Microscopy

April 10, 2023

Author(s)

Jingjia Meng, Jonathan Goodwill, Evgheni Strelcov, Kefei Bao, Jabez J. McClelland, Marek Skowronski

Understanding the physical changes during electroformation and switching processes in transition-metal-oxide-based non-volatile memory devices is important for advancing this technology. Relatively few characteristics of these devices have been assessed in

Quantum back-action limits in dispersively measured Bose-Einstein condensates

April 8, 2023

Author(s)

Ian Spielman, Emine Altuntas

A fundamental tenet of quantum mechanics is that measurements change a system's wavefunction to that most consistent with the measurement outcome, even if no observer is present. Weak measurements produce only limited information about the system, and as a

A critical examination of robustness and generalizability of machine learning prediction of materials properties

April 7, 2023

Author(s)

Kangming LI, Brian DeCost, Kamal Choudhary, Michael Greenwood, Jason Hattrick-Simpers

Recent advances in machine learning (ML) have led to substantial performance improvement in material database benchmarks, but an excellent benchmark score may not imply good generalization performance. Here we show that ML models trained on Materials

Forensic Seized Drug Analysis: Current Challenges and Emerging Analytical Solutions

April 7, 2023

Author(s)

Monica Joshi, Edward Sisco

Over the past decade, seized drug analysis has been faced with several unique challenges that have pushed the limits of existing instrumentation and workflows. Practitioners are now often faced with increasing caseloads of complex samples that may contain

The optical and magnetic properties of Ru-doped hybrid improper perovskite Ca3Mn2O7 via experimental and first-principles calculations

April 7, 2023

Author(s)

Kejia Yuan, Hanwen Zhang, Tianqi Xiao, Zhiyan Li, Winnie Wong-Ng, Wei Zhou, Chao Wang, Shouyu Wang, Weifang Liu

The quasi-2D Ruddlesden-Popper layered perovskites with single-phase multiferroicity have attracted much attention in recent magnetoelectric memory applications. We have systematically investigated the optical and magnetic properties of Ru-doped hybrid

Accelerated Weak Signal Search Using Mode Entanglement and State Swapping

April 6, 2023

Author(s)

Y. Jiang, E.P., Ruddy, K.O. Quinlan, Maxime Malnou, Nicholas Frattini, Konrad Lehnert

Berlin Statement on Legacy and Emerging Contaminants in Polar Regions

April 6, 2023

Author(s)

Rebecca Pugh, Ralf Ebinghaus, Elena Barbaro, Susan Bengtson Nash, Cristina de Avila, Cynthia de Wit, Valeria Dulio, Janine Felden, Antonio Franco, Juergen Gandrass, Marco Grotti, Heike Herata, Kevin Hughes, Morten Jartun, Hanna Joerss, Roland Kallenborn, Jan Koschorreck, Anette Kuster, Rainer Lohmann, Zhanyun Wang, Matthew MacLeod, Caren Rauert, Jaroslav Slobodnik, Roxana Suhring, Katrin Vorkamp, Zhiyong Xie

Polar regions should be given greater consideration with respect to chemical monitoring, chemicals risk assessment, and management, consistent with requirements of the precautionary principle. Protecting the vulnerable polar environments requires (i)

Elastic-Plastic Properties of Meso-scale Electrodeposited LIGA Nickel Alloy Films: Analysis of Measurement Uncertainties

April 6, 2023

Author(s)

Li-Anne Liew, David T. Read, May Ling Martin, Peter Bradley, John T. Geaney

It is well documented that the microstructure and properties of electrodeposited films, such as LIGA Ni and its alloys, are highly sensitive to processing conditions hence the literature shows large discrepancies in mechanical properties, even for similar

Protocol for structure determination of unknowns by EI mass spectrometry. II. Diagnostic ions in one ring alicyclic, heterocyclic, and aromatic compounds

April 6, 2023

Author(s)

Anzor I. Mikaia

Mass spectra of saturated carbocyclic hydrocarbons containing a single three, four, five, six, seven and more membered ring are discussed followed by the examination of their unsaturated analogs including aromatic hydrocarbons. Mass spectrometry

Robust Nuclear Spin Entanglement via Dipolar Interactions in Polar Molecules

Security Segmentation in a Small Manufacturing Environment

April 6, 2023

Author(s)

Michael Powell, John Hoyt, Aslam Sherule, Lynette Wilcox

Manufacturers are increasingly targeted in cyber-attacks. Small manufacturers are particularly vulnerable due to limitations in staff and resources to operate facilities and manage cybersecurity. Security segmentation is a cost-effective and efficient
