The Social Media Genome: Modeling Individual Topic-Specific Behavior in Social Media
Petko Bogdanov, Michael Busch, Jeff Moehli +2
Information propagation in social media depends not only on the static follower structure but also on the topic-specific user behavior. Hence novel models incorporating dynamic use…
A spectral comparison of (379) Huenna and its satellite
Francesca DeMeo, Benoit Carry, Franck Marchis +7
We present near-infrared spectral measurements of Themis family asteroid (379) Huenna (D~98 km) and its 6 km satellite using SpeX on the NASA IRTF. The companion was farther than 1…
A Nonparametric Adaptive Nonlinear Statistical Filter
Michael Busch, Jeff Moehlis
We use statistical learning methods to construct an adaptive state estimator for nonlinear stochastic systems. Optimal state estimation, in the form of a Kalman filter, requires kn…
Linking the Solar System and Extrasolar Planetary Systems with Radar Astronomy: Infrastructure for "Ground Truth" Comparison
Joseph Lazio, Amber Bonsall, Marina Brozovic +13
Planetary radars have obtained unique science measurements about solar system bodies and they have provided orbit determinations allowing spacecraft to be navigated throughout the…
Dynamic Memory Allocation Policies for Postings in Real-Time Twitter Search
Nima Asadi, Jimmy Lin, Michael Busch
We explore a real-time Twitter search application where tweets are arriving at a rate of several thousands per second. Real-time search demands that they be indexed and searchable…
The Benefits and Harms of Transmitting Into Space
Jacob Haqq-Misra, Michael Busch, Sanjoy Som +1
Deliberate and unintentional radio transmissions from Earth propagate into space. These transmissions could be detected by extraterrestrial watchers over interstellar distances. He…
