Model Prior Distribution for Variable Selection in Linear Regression Models
Cristiano Villa, Jeong Eun Lee
In this work we discuss a novel model prior probability for variable selection in linear regression. The idea is to determine the prior mass in an objective sense, by considering t…
Pricing-based Distributed Energy-Efficient Beamforming for MISO Interference Channels
Pan Cunhua, Xu Wei, Wang Jiangzhou +4
In this paper, we consider the problem of maximizing the weighted sum energy efficiency (WS-EE) for multi-input single-output (MISO) interference channels (ICs) which is well ackno…
Are fractured cliffs the source of cometary dust jets ? Insights from OSIRIS/Rosetta at 67P
J. -B. Vincent, N. Oklay, M. Pajola +52
Dust jets, i.e. fuzzy collimated streams of cometary material arising from the nucleus, have been observed in-situ on all comets since the Giotto mission flew by comet 1P/Halley in…
Survival of the impactor during hypervelocity collisions I: An analogue for low porosity targets
C. Avdellidou, M. C. Price, M. Delbo +2
Recent observations of asteroidal surfaces indicate the presence of materials that do not match the bulk lithology of the body. A possible explanation for the presence of these exo…
Intuitionistic nonstandard bounded modified realisability and functional interpretation
Bruno Dinis, Jaime Gaspar
We present a bounded modified realisability and a bounded functional interpretation of intuitionistic nonstandard arithmetic with nonstandard principles. The functional interpretat…
Observational constraints on star cluster formation theory - I. The mass-radius relation
S. Pfalzner, H. Kirk, A. Sills +5
Stars form predominantly in groups usually denoted as clusters or associations. The observed stellar groups display a broad spectrum of masses, sizes and other properties, so it is…
