On-Wafer Calibration Comparisons of Multiline TRL with Platinum and Gold Conductors

July 30, 2024
Author(s)
Tomasz Karpisz, Jacob Pawlik, Johannes Hoffmann, Sarah Evans, Christian Long, Nathan Orloff, James Booth, Angela Stelson
On-wafer calibrations are critical for measurements of embedded devices at the correct reference planes. A major challenge in on-wafer calibrations is the development of accurate calibrations that cover a frequency range from MHz to THz. Another challenge

Ultrahigh reflectivity photonic crystal membranes with optimal geometry

July 30, 2024
Author(s)
Feng Zhou, Yiliang Bao, Jason Gorman, John R. Lawall
Photonic crystal (PhC) structures with subwavelength periods are widely used for diffractive optics, including high reflectivity membranes with nanoscale thickness. Here, we report on a design procedure for 2D PhC silicon nitride membrane mirrors providing

Advances in Yeast Synthetic Biology for Human GPCR Biology and Pharmacology

July 29, 2024
Author(s)
Geoffrey Taghon, Nicholas Kapolka, Daniel Isom
G protein-coupled receptors (GPCRs) are the largest family of transmembrane receptors in humans. Over 800 GPCRs regulate the (patho)biology of every organ, tissue, and cell type. Consequently, GPCRs are the most prominent therapeutic targets in medicine

Coherent coupling and non-destructive measurement of trapped-ion mechanical oscillators

July 29, 2024
Author(s)
Panyu Hou, Jenny Wu, Stephen Erickson, Daniel Cole, Giorgio Zarantonello, Adam Brandt, Andrew C. Wilson, Daniel Slichter, Dietrich Leibfried
Precise quantum control and measurement of several harmonic oscillators, such as the modes of the electromagnetic field in a cavity or of mechanical motion, are key for their use as quantum platforms. The motional modes of trapped ions can be individually

Magnetic skin effect in Pb(Fe1/2Nb1/2)O3

July 29, 2024
Author(s)
Guangyong Xu, Peter M. Gehring
Relaxor-ferroelectrics display exceptional dielectric properties resulting from the underlying random dipolar fields induced by strong chemical inhomogeneity. An unusual structural aspect of relaxors is a skin-effect where the near-surface region in single

Magnetic Skin Effect in Pb(Fe1/2Nb1/2)O3

July 29, 2024
Author(s)
Nathan Giles-Donovan, A. D. Hillier, K Ishida, B.V. Hampshire, S. Giblin, B. Roessli, Peter M. Gehring, Guangyong Xu, Xiaobing Li, Haosu Luo, Sandy Cochran, C. Stock
Relaxor-ferroelectrics display exceptional dielectric properties resulting from the underlying random dipolar fields induced by strong chemical inhomogeneity. An unusual structural aspect of relaxors is a skin-effect where the near-surface region in single

Similarity Measures of Mass Spectra in Hilbert Spaces

July 29, 2024
Author(s)
Anthony J. Kearsley, Matthew Roberts
Mass spectrometry (MS) is an analytic tool for measuring mass-to-charge ratios of molecules or molecular fragments. It is often used to identify and classify compounds. A mass spectrometer measures the mass of molecules and produces a signal proportional

Super-resolution Localization and Tracking in WiFi Sensing

July 29, 2024
Author(s)
Jian Wang, Jack Chuang, Nada Golmie
Integrated sensing and communication (ISAC) systems have been investigated by the research and standardization communities in the recent past. Accurate localizing the target and tracking the target's movement are critical for numerous smart Internet of

Generation of Neutron Airy Beams

Author(s)
Charles W. Clark, Dmitry Pushin, Michael G. Huber, Kirill Zhernenkov, Jonathan White, Lisa DeBeer-Schmitt, David Cory, Huseyin Ekinici, Melissa Henderson, Owen Lailey, Dusan Sarenac
The Airy wave packet is a solution to the potential-free Schr¨odinger equation that exhibits remark-able properties such as self-acceleration, non-diffraction, and self-healing. Although Airy beams are now routinely realized with electromagnetic waves and

A Plan for Global Engagement on AI Standards

Christian Hulzebos, Johanna Camara, Miranda van Berkel, VINCENT DELATOUR, Stanley Lo, Agnes Mailloux, Marcel Schmidt, Mercy Thomas, Lindsey Mackay, Ronda Greaves
Measurement of total serum bilirubin (TSB) concentration is the gold standard approach for diagnosing neonatal unconjugated hyperbilirubinemia. It is of utmost importance that the measured TSB concentration is sufficiently accurate to prevent

Uncovering the Timescales of Spin Reorientation in TbMn6Sn6
