Characterizing Speed and Scale of Cryptocurrency Discussion Spread on Reddit

The World Wide Web Conference, 2019
Cryptocurrencies are a novel and disruptive technology that has prompted a new approach to how currencies work in the modern economy. As such, online discussions related to cryptocurrencies often go beyond posts about the technology and underlying architecture of the various coins, to subjective speculations of price fluctuations and predictions ...

Success, failure, and spreading speeds for invasions on spatial gradients

Journal of Mathematical Biology, 2014
We study a model that describes the spatial spread of a species along a habitat gradient on which the species' growth increases. Mathematical analysis is provided to determine the spreading dynamics of the model. We demonstrate that the species may succeed or fail in local invasion depending on the species' growth function and dispersal kernel.

Collimation of High-speed Flow with Thermal Spread Losses

AIAA Journal, 1979
The operation of the neutral beam collimator designed for the mass spectrometer inlet system of the Space Shuttle Induced Environment Contamination Monitor system is discussed. The collimator will allow selective views of a 10 deg half-angle conical volume of space so that backscattered molecules from within this volume can be measured and related to ...
