Improvement Of Cryo-Em Maps By Density Modification, Thomas C Terwilliger, Steven J Ludtke, Randy J Read, Paul D Adams, Pavel V Afonine

Faculty, Staff and Students Publications

A density-modification procedure for improving maps from single-particle electron cryogenic microscopy (cryo-EM) is presented. The theoretical basis of the method is identical to that of maximum-likelihood density modification, previously used to improve maps from macromolecular X-ray crystallography. Key differences from applications in crystallography are that the errors in Fourier coefficients are largely in the phases in crystallography but in both phases and amplitudes in cryo-EM, and that half-maps with independent errors are available in cryo-EM. These differences lead to a distinct approach for combination of information from starting maps with information obtained in the density-modification process. The density-modification procedure was …

The Interaction Of Adversity, Hope, Social Support, And Academic Resilience In Emerging Appalachian Adults, Daniel Joseph Gottron Jr.

Electronic Theses and Dissertations

The negative impact of adverse childhood experiences on both short-term and long-term wellbeing has been repeatedly validated across multiple populations. While adverse childhood experiences have been thoroughly researched in many contexts, this is not the case for Appalachia, which has often been relegated to the fringe of scholarly research, resulting in an overall lack of research on Appalachia. Further lacking is research into how protective factors might be utilized to help overcome adversity. While some recent research on the relationship between adverse childhood experiences, hope, and resilience has been conducted, it too has been limited to select populations. It is …

School of Medicine Publications

In recent years, replicability of neuroscientific findings, specifically those concerning correlates of morphological properties of gray matter (GM), have been subject of major scrutiny. Use of different processing pipelines and differences in their estimates of the macroscale GM may play an important role in this context. To address this issue, here, we investigated the cortical thickness estimates of three widely used pipelines. Based on analyses in two independent large-scale cohorts, we report high levels of within-pipeline reliability of the absolute cortical thickness-estimates and comparable spatial patterns of cortical thickness-estimates across all pipelines. Within each individual, absolute regional thickness differed between …
