Atomic-level study of dose-dependent lattice thermal conductivity degradation in irradiated tungsten
Mary K Chessey, José Julio Gutiérrez Moreno, Sajjan Singh Mehta +5
Plasma-facing components (PFCs) in future fusion reactors must withstand extreme environments, making tungsten (W) a prime candidate material due to its high thermal conductivity,…
Missing Data on Physics Exams: Demographic Patterns, Course-Level Predictions, and Implications for Equity
Cassandra Paul, David J. Webb, Mary Kate Chessey
In a previous quantitative retrospective study we showed that different demographic groups of students leave different numbers of problems blank on physics exams, leading to inequi…
Relative impacts of different grade-scales on student success in introductory physics
David J. Webb, Cassandra A. Paul, Mary K. Chessey
In deciding on a student's grade in a class, an instructor generally needs to combine many individual grading judgments into one overall judgment. Two relatively common numerical s…
Pondering zeros: analysis of a decade of blanks and missed quizzes
Cassandra Paul, David J. Webb, Mary K. Chessey +1
When assessing student work, graders will often find that some students will leave one or more problems blank on assessments. Since there is no work shown, the grader has no means…
Fold Lens Flux Anomalies: A Geometric Approach
David M. Goldberg, Mary K. Chessey, Wendy B. Harris +1
We develop a new approach for studying flux anomalies in quadruply-imaged fold lens systems. We show that in the absence of substructure, microlensing, or differential absorption,…
