- Description:
- The Brune source model is widely used in studies of complex earthquakes with multiple episodes of high moment release (i.e., multiple subevents). In this study, we investigate how corner frequency estimates of earthquakes with multiple subevents are biased if they are based on the Brune source model. By assuming complex sources as a sum of multiple Brune sources, we analyze 1,640 source time functions (STFs) of Mw 5.5-8.0 earthquakes in the SCARDEC catalog to estimate the corner frequencies, onset times, and seismic moments of subevents. We identify more subevents for strike-slip earthquakes than dip-slip earthquakes, and the number of resolvable subevents increases with magnitude. We find that earthquake corner frequency correlates best with the corner frequency of the subevent with the highest moment release (i.e., the largest subevent). This suggests that, when the Brune model is used, the estimated corner frequency and therefore the stress drop of a complex earthquake is determined primarily by the largest subevent rather than the total rupture area. and Our results imply that the stress variation of asperities, rather than the average stress change of the whole fault, contributes to the large variance of stress drop estimates.

- Description:
- This study investigated the mediating role of emotion dysregulation in the association between childhood trauma and food addiction. Participants (n=310) completed self-report measures of food addiction, childhood trauma experiences, emotion dysregulation, and demographic variables. Pearson zero-order correlations were conducted to identify potential covariates. Age, socioeconomic status, BMI, and education were significantly associated with study variables and were included as covariates in analyses. Moderated mediational analyses were used to investigate whether DERS (emotion regulation) mediated the association between the CTQ (childhood trauma) and YFAS2.0 (food addiction) and to explore whether gender identity (men vs women) moderated this association. Emotion dysregulation partially mediated associations between food addiction and childhood trauma. Gender moderated associations between childhood trauma and emotion dysregulation as well as childhood trauma and food addiction. Both moderating pathways were significantly stronger for men compared to women. Results suggest that emotion dysregulation may be an important mediating factor in the association between childhood trauma and food addiction, particularly for men.

- Description:
- The dataset includes 51 children (age range = 6-12 years) who listened to the first chapter of Alice’s Adventures in Wonderland during fNIRS neuroimaging. We also provide the text of the story with several word-by-word predictors motivated by research in Theory of Mind development and language. These annotated, naturalistic datasets can be used to replicate prior work and test new hypotheses about everyday social cognition and natural language comprehension in the developing brain.

- Description:
- This random sample of OA articles comes from Deep Blue <deepblue.lib.umich.edu/documents>, the University of Michigan’s institutional repository service. Each OA article has the following characteristics: Prior to a known date (ranging from 2006 to the 2013) these articles—the final published version—were only available by subscription. After that date, they became freely available via Deep Blue. Meanwhile, other articles from the same journal issue as the now-OA article continued to only be available to subscribers. None of the OA articles were self-selected; authors did not choose to deposit the articles in question in Deep Blue, since we made them open via blanket licensing agreements between the publishers and the library.

- Description:
- We created various files, including GIS files and data files for both the UM Hydrologic Modeling Team and for our own Escherichia coli sampling project. The UM Hydrologic Team used the files we created to make their models more accurate. For example, we edited Clinton River subwatershed files to better reflect below and above-ground infrastructure, and provided them to the modeling team. For our own E. coli subproject we created time series, GIS files, and R code to better understand the influence of precipitation and streamflow on E. coli dynamics. Our time-series data is based on baseline and storm sampling we conducted in the summer of 2021. We used GIS files to explore the subwatersheds of our E. coli sampling locations. Finally, we created R code to help us visualize and analyze the data.

- Description:
- These data were produced from a study that assessed mitochondrial metabolic function by measuring two metabolites, l-carnitine and acetylcarnitine, to determine their effectiveness as candidate clinical biomarkers for age-related, drug-induced alterations in mitochondrial metabolism. To study age and medication-related changes in mitochondrial metabolism, we administered the FDA-approved mitochondriotropic drug, clofazimine (CFZ), or vehicle for to young and old mice. These findings are described in our manuscript: Clofazimine-Mediated, Age-Related Changes in Skeletal Muscle Mitochondrial Metabolites. Data reported was supported by funding from the National Institute of General Medical Sciences (NIGMS) at the National Institutes of Health (NIH) under award numbers R01GM127787 (GRR), R35GM136312 (KAS), P30AR069620 (K Jepsen), and T32GM140223 (L Isom).

- Description:
- This study investigated co-occurrence among food addiction (FA), problematic substance use (alcohol, cannabis, cigarettes, nicotine vaping), parental history of problematic alcohol use, and obesity. Participants (n=357) completed self-report measures on food addiction, personal substance use, and parental history of alcohol use. Participants also completed demographic questions and self-reported height and weight were used to calculate BMI. Pearson zero-order correlations were conducted to identify sociodemographic covariates (socioeconomic status, age, and sex at birth). Modified Poisson regression (with robust standard error estimations) were used to estimate risk ratios among food addiction, parental history of problematic alcohol use, personal substance use (alcohol, cannabis, cigarettes, nicotine vaping), and obesity. Significance was set at p<.05. However, given multiple testing, 99% CI estimates are reported in the final manuscript instead of 95% CI estimates. Unadjusted and adjusted (for sociodemographic covariates) analyses were conducted. Risk of food addiction was higher in participants with problematic alcohol, smoking, vaping, parental history of problematic alcohol use, and (in unadjusted only) cannabis use. Risk of food addiction was only higher in participants with obesity after adjusting for covariates. Obesity was not significantly associated with problematic substance use and parental history or problematic alcohol use. Thus, food addiction, but not obesity, co-occurred with problematic substance use and a family history of problematic alcohol use. Results support the conceptualization of food addiction as an addictive disorder.

- Description:
- The most important part of this deposit is the code necessary for simulating the anisotropic phase-field crystal on a cone geometry. The second most important is the code for analyzing the simulation results, including the spatial distribution of Y-junctions in the simulated retinae. Included are simulation results in which we systematically scan both the undercooling parameters and the strength of noise in the initial conditions. Finally, we include an additional simulation example (as in Figure 7D). Please see readme file for description of main (MATLAB) functions used for simulating and analyzing simulations.
