A class of axially symmetric, rotating four-dimensional geometries carrying D1, D5, KKmonopole and momentum charges is constructed. The geometries are found to be free of horizons and singularities, and are candidates to be the gravity duals of microstates of the (0,4) CFT. These geometries are constructed by performing singularity analysis on a suitably(More)
Understanding students’ self-ascribed engineering identity may be one way to understand engineering choices and to help recruit new students to the engineering pipeline. In our framework, identity is composed of students’ perceptions of their performance/competence, recognition, and interest in a domain. This paper outlines the creation of a model of(More)
We review what has been learnt and what remains unknown about the physics of hot enhançons following studies in supergravity. We recall a rather general family of static, spherically symmetric, non-extremal enhançon solutions describing D4 branes wrapped on K3 and discuss physical aspects of the solutions. We embed these solutions in the six dimensional(More)
[This paper is part of the Focused Collection on Gender in Physics.] Active-learning approaches to teaching introductory physics have been found to improve student learning and affective gains on shortterm outcomes [S. Freeman et al., Proc. Natl. Acad. Sci. U.S.A. 111, 8410 (2014)]; however, whether or not the benefits of active learning impact women to the(More)

Todd is a PhD Student in Engineering Education at Purdue University who's research is focused on en-trepreneurship education and entrepreneurship education as a component of modern engineering education efforts. research focuses what factors influence diverse students to choose engineering and stay in engineering through their careers and how different(More)
We report on a study of the effect of peers' interest in high school biology, chemistry, and physics classes on students' STEM (science, technology, engineering, and mathematics)-related career intentions and course achievement. We define an interest quorum as a science class where students perceive a high level of interest for the subject matter from their(More)
