Di usion in poro - plastic media

A model is developed for the ow of a slightly compressible uid through a saturated inelastic porous medium. The initial-boundary-value problem is a system that consists of the di usion equation for the uid coupled to the momentum equation for the porous solid together with a constitutive law which includes a possibly hysteretic relation of elasto-visco-plastic type. The variational form of this...

Reaction-Di usion Fronts in Periodically Layered Media

We compute the e ective wave front speeds of reaction-di usion equations in periodically layered media with coe cents that have small amplitude oscillations around a uniform mean state. We compare them with the corresponding wave front speeds in the uniform state. We analyze a one dimensional model where wave propagation is along the layering direction of the medium and a two dimensional shear ...

Understanding Musical Diversity via Online Social Media

Musicologists and sociologists have long been interested in patterns of music consumption and their relation to socioeconomic status. In particular, the Omnivore Thesis examines the relationship between these variables and the diversity of music a person consumes. Using data from social media users of Last.fm and Twitter, we design and evaluate a measure that reasonably captures diversity of mu...

Online Tie Formation in Enterprise Social Media

We study the antecedents to tie formation on an enterprise social media platform implemented to support cross-boundary connections. Research has produced mixed findings regarding the role of social media in cultivating bridging vs. closed networks. We examine the tie formation patterns of 1,386 enterprise social media users over a two-year period. We first find that users tend to form ties via ...
