    • The First Scale of Attention: Linguistic Form and Aesthetic Experience in the Novel 

      Pane, Greta Lynn (2013-08-27)
      We read a novel one sentence at a time. The first scale of attention for even the longest novel is the play of forces within the thousands of individual sentences. This project aims to rescale the analysis of novelistic ...

      DiSciacca, Jack Michael (2013-09-23)
      We report a new comparison of the proton (p) and antiproton \((\bar{p})\) magnetic moments. In nuclear magnetons, \(\mu_p/\mu_N\) = 2.792 846 (7) [2.5 ppm], while \(\mu_{\bar{p}}/\mu_N\) = 2.792 845 (12) [4.4 ppm]. The ...

    • First stars of the ρ Ophiuchi dark cloud 

      Pillitteri, I.; Wolk, Scott J.; Chen, Hope How-Huan; Goodman, Alyssa (EDP Sciences, 2016)
      Star formation in molecular clouds can be triggered by the dynamical action of winds from massive stars. Furthermore, X-ray and UV fluxes from massive stars can influence the life time of surrounding circumstellar disks. ...

    • First Structure Formation: A Simulation of Small‐Scale Structure at High Redshift 

      Jang-Condell, Hannah; Hernquist, Lars (American Astronomical Society, 2001)
      We describe the results of a simulation of collisionless cold dark matter in a Lambda CDM universe to examine the properties of objects collapsing at high redshift (z = 10). We analyze the halos that form at these early ...
