Democratizing Children's Computation: Learning Computational Science as Aesthetic Experience

Amy Farris, Pratim Sengupta

In this paper, we argue that a democratic approach to children's computing education in a science class must focus on the aesthetics of children's experience. In Democracy and Educ…

Recurring Occultations of RW Aurigae by Coagulated Dust in the Tidally Disrupted Circumstellar Disk

Joseph E. Rodriguez, Phillip A. Reed, Robert J. Siverd +7

We present photometric observations of RW Aurigae, a Classical T Tauri system, that reveal two remarkable dimming events. These events are similar to that which we observed in 2010…

A Granulation "Flicker"-based Measure of Stellar Surface Gravity

Fabienne A. Bastien, Keivan G. Stassun, Gibor Basri +1

In Bastien et al. (2013) we found that high quality light curves, such as those obtained by Kepler, may be used to measure stellar surface gravity via granulation-driven light curv…

Two-body dissipation effects on synthesis of superheavy elements

M. Tohyama, S. Umar

To investigate the two-body dissipation effects on the synthesis of superheavy elements, we calculate low-energy collisions of the isotones (Ge, Se, Kr…

Codegree thresholds for covering 3-uniform hypergraphs

Victor Falgas-Ravry, Yi Zhao

Given two 3-uniform hypergraphs F and G, we say that G has an F-covering if we can cover V(G) by copies of F. The minimum codegree of G is the largest integer d such that every pai…

Measurement of differential and integrated fiducial cross sections for Higgs boson production in the four-lepton decay channel in pp collisions at sqrt(s) = 7 and 8 TeV

CMS Collaboration

Integrated fiducial cross sections for the production of four leptons via the H to 4l decays (l = e, mu) are measured in pp collisions at sqrt(s) = 7 and 8 TeV. Measurements are pe…
