Quantifying Trapped Magnetic Vortex Losses In Niobium Resonators At Mk Temperatures, D. Bafia, B. Abdisatarov, R. Pilipenko, Y. Lu, G. Eremeev, A. Romanenko, A. Grassellino

Electrical & Computer Engineering Faculty Publications

Trapped magnetic vortices in niobium introduce microwave losses that degrade the performance of superconducting resonators. While such losses have been extensively studied above 1 K, we report here their direct quantification in the millikelvin and low-photon regime relevant to quantum devices. Using a high-quality factor 3D niobium cavity cooled through its superconducting transition in controlled magnetic fields, we isolate vortex-induced losses and find the resistive component of the sensitivity to trapped flux S to be approximately 2 n Ω/mG at 10 mK and 6 GHz. The decay rate is initially dominated by two-level system (TLS) losses from the native niobium …

The Effect Of Electrode Geometry On Excited Species Production In Atmospheric Pressure Air–Hydrogen Streamer Discharge, Shirshak Kumar Dhali, Stuart Reyes

Electrical & Computer Engineering Faculty Publications

When a gas is overvolted at or near atmospheric pressure, it results in a streamer discharge formation. Electrode geometries exert significant impact on the electrical breakdown of gases by altering the spatial profile of the electric field. In many applications the efficient generation of radicals is critical and is determined by the characteristics of the streamer discharge. We examine the effect of electrode geometry on the streamer characteristics and the production of radicals. This is performed for three different electrode geometries: plane–plane, pin–plane, and pin–pin. A two-dimensional rotationally symmetric fluid model is used for the streamer discharge simulation in the …

Department of Biomedical and Translational Sciences Faculty Publications

Every heartbeat depends on cyclical contraction-relaxation produced by the interactions between myosin-containing thick and actin-based thin filaments (TFs) arranged into a crystalline-like lattice in the cardiac sarcomere. Therefore, the maintenance of thin filament length is crucial for myocardium function. The thin filament is comprised of an actin backbone, the regulatory troponin complex and tropomyosin that controls interactions between thick and thin filaments. Thin filament length is controlled by the tropomodulin family of proteins; tropomodulin caps pointed ends of thin filaments, and leiomodin (Lmod) promotes elongation of thin filaments by a “leaky-cap” mechanism. The broader distribution of Lmod on the thin …

Association Between The Intensity Of Exercise In The First Trimester And Early Second Trimester And The Risk Of Gestational Diabetes, Takaki Tanamoto, Misa Hayasaka, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

Objective

Although some studies show that exercise decreases the incidence of gestational diabetes mellitus (GDM), the optimal exercise intensity during pregnancy remains unclear. We examined GDM risk according to exercise intensity in pregnant individuals.

Methods

We analyzed data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers‐to‐Be (nuMoM2b), a prospective study enrolling nulliparous individuals in the first trimester. Participants with pregestational diabetes or delivery before 20 weeks were excluded. Exercise intensity during the first (6–13 weeks’ gestation) and early second (16–21 weeks’ gestation) trimesters was categorized by metabolic equivalent of task hours per week (MET‐hr/week) as none, low intensity (< 7.5), moderate intensity (7.5–14.9), or high intensity (≥ 15). The primary outcome was GDM; secondary outcomes included preeclampsia, gestational hypertension, preterm birth, small‐for‐gestational‐age birth, and stillbirth. Adjusted relative risks (aRRs) with 95% confidence intervals (CIs) were calculated using a generalized linear mixed‐effects model with a Poisson distribution and robust error variance, controlling for the random effects of individuals and potential confounders.
