Co-education and Collaboration: Women at Gettysburg from 1945-1955

Women studying at Gettysburg College in the years following World War II (from 1945 to 1955) were given many freedoms and opportunities not previously experienced by female students of the college. The inclusion of sororities and co-educational social clubs open to both men and women expanded the social lives of female students at Gettysburg. Meanwhile, the dormitory environment and intramural sports teams helped women at Gettysburg create a sense of community through healthy competition. With all of these new social, academic, and extracurricular opportunities, there were still setbacks for women. Rules dictated how a woman could dress in certain settings or wear her hair, a concept that now seems ridiculous. Expectations surrounding a woman’s place in society led many women to not continue their studies after getting engaged or married during their college years. All that considered, women at Gettysburg had rich academic and social lives, complete with opportunities to expand their horizons inside and outside of the class, even if they were not always considered equal to their male classmates

Persistence and Memory in Patchwork Dynamics for Glassy Models

Slow dynamics in disordered materials prohibits direct simulation of their rich nonequilibrium behavior at large scales. "Patchwork dynamics" is introduced to mimic relaxation over a very broad range of time scales by equilibrating or optimizing directly on successive length scales. This dynamics is used to study coarsening and to replicate memory effects for spin glasses and random ferromagnets. It is also used to find, with high confidence, exact ground states in large or toroidal samples.Comment: 4 pages, 4 figures; reference correctio

Short-Term Memory in Orthogonal Neural Networks

We study the ability of linear recurrent networks obeying discrete time dynamics to store long temporal sequences that are retrievable from the instantaneous state of the network. We calculate this temporal memory capacity for both distributed shift register and random orthogonal connectivity matrices. We show that the memory capacity of these networks scales with system size.Comment: 4 pages, 4 figures, to be published in Phys. Rev. Let
