Numerical Determination Of Monopole Scaling Dimension In Parity-Invariant Three-Dimensional Noncompact Qed, Nikhil Karthik, Rajamani Narayanan
Numerical Determination Of Monopole Scaling Dimension In Parity-Invariant Three-Dimensional Noncompact Qed, Nikhil Karthik, Rajamani Narayanan
Department of Physics
We present a direct Monte Carlo determination of the scaling dimension of a topological defect operator in the infrared fixed point of a three-dimensional interacting quantum field theory. For this, we compute the free energy to introduce the background gauge field of the Q=1 monopole-antimonopole pair in three-dimensional noncompact QED with N=2, 4 and 12 flavors of massless two-component fermions, and study its asymptotic logarithmic dependence on the monopole-antimonopole separation. We estimate the scaling dimension in the N=12 case to be consistent with the large-N (free fermion) value. We find the deviations from this large-N value for N=2 and 4 …
Understanding The Importance Of Graduate Admissions Criteria According To Prospective Graduate Students, Deepa Chari, Geoff Potvin
Understanding The Importance Of Graduate Admissions Criteria According To Prospective Graduate Students, Deepa Chari, Geoff Potvin
Department of Physics
Understanding perceptions of graduate admissions from multiple stakeholders can cultivate an improved understanding about the process of graduate induction, the role that admissions plays in restricting diversity in physics, and contribute to more informed practices for all involved. Prior studies in graduate admissions have reported on how certain admission criteria weigh in the consideration of applicants primarily from faculty perspectives. Motivated by the concept of multivocal knowledge, in this article, we report on prospective students’ perspectives of the importance of the same admission criteria—a stakeholder group that is critical but underempowered in the admissions process. We identify a substantial agreement …

Qcd Evolution Of Superfast Quarks, Adam J. Freese, Wim Cosyn, Misak M. Sargsian

Recent high-precision measurements of nuclear deep inelastic scattering at high x and moderate 6superfast region, in which the momentum fraction of the nucleon carried by its constituent quark is larger than the total fraction of the nucleon at rest, x>1. We derive the leading-order QCD evolution equation for such quarks with the goal of relating the moderate-Q2 data to the two earlier measurements of superfast quark distributions at large 601.1 region is somewhat in the middle of the neutrino-nuclear and muon-nuclear scattering data.
Automated, Efficient, And Accelerated Knowledge Modeling Of The Cognitive Neuroimaging Literature Using The Athena Toolkit, Michael C. Riedel, Taylor P. Salo, Jason Hays, Matthew D. Turner, Matthew T. Sutherland, Jessica A. Turner, Angela Laird

Neuroimaging research is growing rapidly, providing expansive resources for synthesizing data. However, navigating these dense resources is complicated by the volume of research articles and variety of experimental designs implemented across studies. The advent of machine learning algorithms and text-mining techniques has advanced automated labeling of published articles in biomedical research to alleviate such obstacles. As of yet, a comprehensive examination of document features and classifier techniques for annotating neuroimaging articles has yet to be undertaken. Here, we evaluated which combination of corpus (abstract-only or full-article text), features (bag-of-words or Cognitive Atlas terms), and classifier (Bernoulli naïve Bayes, k-nearest …
Sexual Harassment Reported By Undergraduate Female Physicists, Lauren M. Aycock, Zahra Hazari, Eric Brewe, Kathryn B.H. Clancy, Theodore Hodapp, Renee Michelle Goertzen

Sexual harassment occurs more frequently in male-dominated fields and physics is a more male-dominated field than most other science, technology, engineering, and mathematics (STEM) fields. Thus, it is important to examine the occurrence and impact of sexual harassment on women in physics. A survey of undergraduate women, who attended a conference for undergraduate women in physics, revealed that approximately three quarters (74.3%; 338/455) of survey respondents experienced at least one type of sexual harassment. This sample was recruited from a large fraction of undergraduate women in physics in the United States. We find that certain types of sexual harassment predict …
