title: First-principles Model for the Anomalous Frictional Heating of Electrons in Hall Thrusters

description: An analytical expression has been developed for the anomalous frictional power density of electrons, Q_ea^R, produced by their interactions with electrostatic turbulence in Hall thrusters. It accompanies another expression derived recently for the anomalous friction force density, R_eα, that led to a closed-form formula for the anomalous momentum-transfer collision frequency (MTCF). The derivations are part of a larger effort to develop first-principles closure models for hybrid numerical simulations. Our theory on which these models are based is that a two-stage evolution of unstable waves occurs in the Hall thruster discharge. First, short-wavelength (kρ_e&gt;1), high-frequency (|ω|~ω_ce) modes that are driven by the cross-field drift E×B/B^2 grow and saturate at a level of turbulence too low to explain the observed measurements. Then the wave energy is dominated by modes of longer wavelength (kρ_e&lt;1) and in the range of the lower-hybrid frequency ω_LH. The anomalous MTCF model we developed compared extremely well with a large set of empirical profiles derived from laser-induced fluorescence measurements that spanned a wide range of thruster geometries, operating conditions and applied magnetic fields. The new expression for the anomalous frictional heating reported here has been derived from the same kinetic theory and shows Q_ea^R is a function of the lower-hybrid wave properties at maximum growth and the drifts that drive it. Compared to phenomenological models that take in to account anomalous heating in the electron fluid energy equation through R_eα in the work term E∙j_e, the kinetic formulation yields as much as 4 higher frictional heating.

title: Time-Resolved Ion Energy Measurements in the SPT-50 Hall Effect Thruster

description: An investigation into time-resolved ion energy measurements of the 300-W SPT-50 Hall effect thruster (HET) utilizing a high-speed retarding potential analyzer (HSRPA) is presented. Ion energy as a function of HET operating condition and downstream position was measured. High-speed measurements were performed with a standard retarding potential analyzer (RPA) in conjunction with high-speed, low-noise circuitry, allowing fast collector current measurements at discrete retarding biases. Time-averaged and time-resolved ion energy measurements were observed to establish a relationship between ion energy, discharge conditions, and downstream position. Time-series data were reconstructed using data fusion techniques allowing time-resolved ion energy distribution functions (IEDFs) to be acquired. Time-resolved ion energy measurements varied in mean, peak-to-peak, and temporal characteristics as the operating conditions and position were varied.

title: Effectively controlling for sample relatedness in large-scale GWAS: application to 79 EHR-derived longitudinal traits

description: Sample relatedness is a major confounder in genome-wide association studies (GWAS), potentially leading to inflated type I error rates if not appropriately controlled. A common strategy is to incorporate a random effect related to genetic relatedness matrix (GRM) into regression models. However, this approach is challenging for large-scale GWAS of complex traits, such as longitudinal traits. Here we propose a scalable and accurate analysis framework, SPAGRM, which controls for sample relatedness via a precise approximation of the joint distribution of genotypes. SPAGRM can utilize GRM-free models and thus is applicable to various trait types and statistical methods, including linear mixed models and generalized estimation equations for longitudinal traits. A hybrid strategy incorporating saddlepoint approximation greatly increases the accuracy to analyze low-frequency and rare genetic variants, especially in unbalanced phenotypic distributions. We also introduce SPAGRM(CCT) to aggregate the results following different models via Cauchy combination test. Extensive simulations and real data analyses demonstrated that SPAGRM maintains well-controlled type I error rates and SPAGRM(CCT) can serve as a broadly effective method. Applying SPAGRM to 79 longitudinal traits extracted from UK Biobank primary care data, we identified 7,463 genetic loci, making a pioneering attempt to conduct GWAS for these traits as longitudinal traits.

title: A scalable, accurate, and universal analysis framework to control for sample relatedness in large-scale genome-wide association studies and its application to 79 longitudinal traits in UK Biobank

description: Sample relatedness is a major confounder in large-scale GWAS and could result in inflation if not appropriately controlled. Incorporating GRM-related random effects into the conventional models is the mostly used strategy. Although effective, it is technically challenging to extend this strategy to other complex traits with complicated structure. In this work, we propose a scalable, accurate, and universal analysis framework, SPAGRM, in which the sample relatedness is controlled via the precise approximation of the joint distribution of genotypes for related samples in families. SPAGRM can utilize GRM-free conventional models and thus is applicable to a wide variety of traits. A hybrid strategy including saddlepoint approximation (SPA) can greatly increase the accuracy to analyze low-frequency and rare genetic variants, especially if the phenotypic distribution is unbalanced. Extensive simulation studies and real data analyses validated that SPAGRM is accurate to control type I error rates and can gain power for a longitudinal trait analysis. Expanding upon the previous studies, we implemented a refined and meticulous QC pipeline to extract 79 longitudinal traits from UK Biobank primary care data. The application of SPAGRM to the 79 longitudinal traits identified 7,463 genetic loci, which is a pioneering attempt to conduct GWAS for a majority of these traits as a longitudinal phenotype.
