Current practices in LC-MS untargeted metabolomics: a scoping review on the use of pooled quality control samples

December 6, 2023
Author(s)
Clay Davis, Corey Broeckling, Richard Beger, Cheng Leo, Raquel Cumeras, Daniel Cuthbertson, Surendra Dasari, Warwick Dunn, Anne Evans, Alvaro Fernandez-Ochoa, Kelli Goodman, Helen Gika, Roy Goodacre, Jennifer Kirwan, Kodra Dritan, Julia Kuligowski, Maria Monge, Jonathan Mosley, Sindhu Nair, Nichole Reisdorph, Stacy Sherrod, Georgios Theodoridis, Candice Ulmer Holland, Dajana Vuckovic, Bo Zhang, Goncalo Gouveia
Untargeted metabolomics is an analytical approach with numerous applications, serving as an effective metabolic phenotyping platform to characterize the small molecules within a biological system. Data quality can be challenging to evaluate and demonstrate

KPI Extraction from Maintenance Work Orders-A Comparison of Expert Labeling, Text Classification and AI-Assisted Tagging for Computing Failure Rates of Wind Turbines

December 6, 2023
Author(s)
Marc-Alexander Lutz, Bastian Schafermeier, Rachael Sexton, Michael Sharp, Alden A. Dima, Stefan Faulstich, Jagan Mohini Aluri
Maintenance work orders are commonly used to document information about wind turbine operation and maintenance. This includes details about proactive and reactive wind turbine downtimes, such as preventative and corrective maintenance. However, the

Logical quantum processor based on reconfigurable atom arrays

December 6, 2023
Author(s)
Dolev Bluvstein, Simon Evered, Alexandra Geim, Sophie Li, Hengyun Zhou, Tom Manovitz, Sepehr Ebadi, Madelyn Cain, Marcin Kalinowski, Dominik Hangleiter, J. Pablo Bonilla Ataides, Nishad Maskara, Iris Cong, Xun Gao, Pedro Rodriguez, Thomas Karolyshyn, Giulia Semeghini, Michael Gullans, Markus Greiner, Vladan Vuletic, Mikahil Lukin
Suppressing errors is the central challenge for useful quantum computing and quantum error correction is believed to be the key to large-scale quantum processing. Here we report the realization of a programmable quantum processor based on encoded logical

Visualizing the merger of tunably coupled graphene quantum dots

December 6, 2023
Author(s)
Daniel Walkup, Fereshte Ghahari, Steven R. Blankenship, Kenji Watanabe, Takashi Taniguchi, Nikolai Zhitenev, Joseph A. Stroscio
Coupled quantum dots have been realized in a wide variety of physical systems and have attracted interest for many different applications. Here, we examine novel graphene quantum dots in backgated devices on hBN, and visualize their merger using scanning

Bipartite time-energy uncertainty relation for quantum metrology with noise

December 5, 2023
Author(s)
Philippe Faist, Mischa Woods, Victor Albert, Joseph Renes, Jens Eisert, John Preskill
Noise in quantum metrology reduces the sensitivity to which one can determine an unknown parameter in the evolution of a quantum state, such as time. Here, we consider a system prepared in a pure state that evolves according to a given Hamiltonian. We

Heats of Combustion and Related Properties of Pure Substances

December 5, 2023
Author(s)
Donald R. Burgess Jr., Anthony Hamins
In this work, we compiled and evaluated various properties pertaining to the heats of combustion of about 420 compounds of physical, chemical, and engineering interest. This includes boiling points, melting points, latent heats (enthalpies) of vaporization

Telecom band quantum dot technologies for long-distance quantum networks

December 4, 2023
Author(s)
Ying Yu, Changmin Lee, Peter Michler, Stephan Reitzenstein, Kartik Srinivasan, Edo Waks, Shunfa Liu, Jin Liu
A future quantum internet is expected to generate, distribute, store and process quantum bits (qubits) over the world by linking different quantum nodes via quantum states of light. To facilitate long-haul operations, quantum repeaters must operate at

Elastic Behavior of Orientation-Correlated Grains in Multiphase Aggregates

December 1, 2023
Author(s)
Thomas Gnaupel-Herold
Diffraction elastic constants (DECs) describe the elastic response of a subset of orientation-correlated grains which share a common lattice vector. DECs reflect the elastic behaviour of the single-crystal constituents through their dependence on grain

Extending Explainable Boosting Machines to Scientific Image Data

November 30, 2023
Author(s)
Daniel Schug, Sai Yerramreddy, Rich Caruana, Craig Greenberg, Justyna Zwolak
As the deployment of computer vision technology becomes increasingly common in science, the need for explanations of the system and its output has become a focus of great concern. Driven by the pressing need for interpretable models in science, we propose

Optomechanical feedback cooling of a 5 mm long torsional mode

November 30, 2023
Author(s)
Dianqiang Su, Yuan Jiang, Pablo Solano, Luis Orozco, John R. Lawall, Yanting Zhao
We report three orders of magnitude optical cooling of the fundamental torsional mode of a 5 mm-long, 550 nm diameter optical nanofiber. The rotation of the nanofiber couples to the polarization of guided laser fields. We use a weak laser probe to monitor
