Coherent states for FLRW space-times in loop quantum gravity
Elena Magliaro, Antonino Marciano, Claudio Perini
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaître-Robertson-Walker type on which they are peaked. The da…
Big Bounce in Dipole Cosmology
Marco Valerio Battisti, Antonino Marciano
We derive the cosmological Big Bounce scenario from the dipole approximation of Loop Quantum Gravity. We show that a non-singular evolution takes place for any matter field and tha…
The Impact of Levene's Test of Equality of Variances on Statistical Theory and Practice
Joseph L. Gastwirth, Yulia R. Gel, Weiwen Miao
In many applications, the underlying scientific question concerns whether the variances of samples are equal. There are a substantial number of tests for this problem. Many of…
Are the Ultra-Faint Dwarf Galaxies Just Cusps?
Adi Zolotov, David W. Hogg, Beth Willman
We develop a technique to investigate the possibility that some of the recently discovered ultra-faint dwarf satellites of the Milky Way might be cusp caustics rather than gravitat…
Centrifugal compression of soft particle packings - theory and experiment
K. N. Nordstrom, E. Verneuil, W. G. Ellenbroek +3
An exact method is developed for computing the height of an elastic medium subjected to centrifugal compression, for arbitrary constitutive relation between stress and strain. Exam…
The Atacama Cosmology Telescope: Extragalactic Sources at 148 GHz in the 2008 Survey
T. A. Marriage, J. B. Juin, Y. -T. Lin +66
We report on extragalactic sources detected in a 455 square-degree map of the southern sky made with data at a frequency of 148 GHz from the Atacama Cosmology Telescope 2008 observ…
