Sheila Govind, Martin Fritzsche, Adrian Jenkins, Megan Cleveland, Peter Vallone, Neil Almond, Clare Morris, Neil Berry
Reactivation of JC and BK polyomaviruses during immunosuppressive transplantation procedures can lead to adverse clinical outcomes. In renal transplant recipients BKV-associated nephropathy can result in graft loss, while prolonged immunomodulatory drug

Methods and lessons for business resilience and recovery surveys

May 25, 2023
Maria Watson, Charlotte Brown, John Handmer, Cynthia Kroll, Anne Wein, Jennifer Helgeson, Adam Rose, Noah Dormady, Juri Kim
Surveys are important tools in business resilience and recovery research because of their ability to capture disaggregated economic information; however, they can be difficult and costly due to business operational dynamics and the larger challenges of

Automated extraction of capacitive coupling for quantum dot systems

May 24, 2023
Joshua Ziegler, Florian Luthi, Mick Ramsey, Felix Borjans, Guoji Zheng, Justyna Zwolak
Gate-defined quantum dots (QDs) have appealing attributes as a quantum computing platform. However, near-term devices possess a range of possible imperfections that need to be accounted for during the tuning and operation of QD devices. One such problem is

Recommendations for Federal Vulnerability Disclosure Guidelines

Arrays of low-temperature microcalorimeters provide a promising technology for X-ray astrophysics: the imaging spectrometer. A camera with at least several thousand pixels, each of which has an energy-resolving power (E∕ΔE_FWHM) of a few thousand across a

Nonlinear Networks for Arbitrary Optical Synthesis

May 19, 2023
Jennifer Black, Zachary Newman, Su-Peng Yu, David Carlson, Scott Papp
Nonlinear wavelength conversion is a powerful control of light, especially when implemented at the nanoscale with integrated photonics. However, strict energy conservation and phase-matching requirements constrain the converted output. To overcome these
