Numerical Evidence for Dark Star Formation: A Comment on "Weakly Interacting Massive Particle Dark Matter and First Stars: Suppression of Fragmentation in Primordial Star Formation" by Smith et al. 2012, ApJ 761, 154
Paolo Gondolo, Katherine Freese, Douglas Spolyar +1
(abridged) This comment is intended to show that simulations by Smith et al. (S12) support the Dark Star (DS) scenario and even remove some potential obstacles. Our previous work i…
Dynamic stochastic blockmodels: Statistical models for time-evolving networks
Kevin S. Xu, Alfred O. Hero
Significant efforts have gone into the development of statistical models for analyzing data in the form of networks, such as social networks. Most existing work has focused on mode…
Predictive Correlation Screening: Application to Two-stage Predictor Design in High Dimension
Hamed Firouzi, Bala Rajaratnam, Alfred Hero
We introduce a new approach to variable selection, called Predictive Correlation Screening, for predictor design. Predictive Correlation Screening (PCS) implements false positive c…
RESLVE: Leveraging User Interest to Improve Entity Disambiguation on Short Text
Elizabeth L. Murnane, Bernhard Haslhofer, Carl Lagoze
We address the Named Entity Disambiguation (NED) problem for short, user-generated texts on the social Web. In such settings, the lack of linguistic features and sparse lexical con…
Socially optimal charging strategies for electric vehicles
Elena Yudovina, George Michailidis
Electric vehicles represent a promising technology for reducing emissions and dependence on fossil fuels and have started entering different automotive markets. In order to bolster…
Binary Frequencies in a Sample of Globular Clusters. I. Methodology and Initial Results
Jun Ji, Joel N. Bregman
Binary stars are thought to be a controlling factor in globular cluster evolution, since they can heat the environmental stars by converting their binding energy to kinetic energy…
