The Majorana Experiment
V. E. Guiseppe
The Majorana Collaboration is assembling an array of HPGe detectors to search for neutrinoless double-beta decay in Ge-76. Initially, Majorana aims to construct a prototype module…
Elliptic flow and nearly perfect fluidity in dilute Fermi gases
Thomas Schaefer
In this contribution we summarize recent progress in understanding the shear viscosity of strongly correlated dilute Fermi gases. We discuss predictions from kinetic theory, and sh…
Particle acceleration in supernova-remnant shocks
S. P. Reynolds
It has been known for over 50 years that the radio emission from shell supernova remnants (SNRs) indicates the presence of electrons with energies in the GeV range emitting synchro…
Nonsmooth Formulation of the Support Vector Machine for a Neural Decoding Problem
Cary Humber, Kazufumi Ito, Chad Bouton
This paper formulates a generalized classification algorithm with an application to classifying (or `decoding') neural activity in the brain. Medical doctors and researchers have l…
Determining reaction cross sections via characteristic X-ray detection: α-induced reactions on 169Tm for the astrophysical γ -process
G. G. Kiss, T. Rauscher, T. Szücs +7
The cross sections of the 169Tm(α, γ)173Lu and 169Tm(α,n)172Lu reactions have been measured first time using a new method, by detecting the characteristic X-ray radiation following…
The influence of collective neutrino oscillations on a supernova r-process
Huaiyu Duan, Alexander Friedland, Gail C. McLaughlin +1
Recently, it has been demonstrated that neutrinos in a supernova oscillate collectively. This process occurs much deeper than the conventional matter-induced MSW effect and hence m…
Subresultants in Multiple Roots
Carlos D'Andrea, Teresa Krick, Agnes Szanto
We extend our previous work on Poisson-like formulas for subresultants in roots to the case of polynomials with multiple roots in both the univariate and multivariate case, and als…
Effect of nonmagnetic substituents Mg and Zn on the phase competition in the multiferroic antiferromagnet MnWO4
Lynda Meddar, Michael Josse, Philippe Deniard +8
The effects of substituting nonmagnetic Mg2+ and Zn2+ ions for the Mn2+ (S = 5/2) ions on the structural, magnetic and dielectric properties of the multiferroic frustrated antiferr…
Viscosity spectral functions of the dilute Fermi gas in kinetic theory
J. Chao, M. Braby, T. Schaefer
We compute the viscosity spectral function of the dilute Fermi gas for different values of the s-wave scattering length , including the unitarity limit . We perform…
Bond-specific reaction kinetics during the oxidation of (111) Si: Effect of n-type doping
Bilal Gokce, David E. Aspnes, Gerald Lucovsky +1
It is known that a higher concentration of free carriers leads to a higher oxide growth rate in the thermal oxidation of silicon. However, the role of electrons and holes in oxidat…
\textsc{MaGe} - a {\sc Geant4}-based Monte Carlo Application Framework for Low-background Germanium Experiments
Melissa Boswell, Yuen-Dat Chan, Jason A. Detwiler +20
We describe a physics simulation software framework, MAGE, that is based on the GEANT4 simulation toolkit. MAGE is used to simulate the response of ultra-low radioactive background…
The Hopf algebra of diagonal rectangulations
Shirley Law, Nathan Reading
We define and study a combinatorial Hopf algebra dRec with basis elements indexed by diagonal rectangulations of a square. This Hopf algebra provides an intrinsic combinatorial rea…
Entropy-driven enhanced self-diffusion in confined reentrant supernematics
Marco G. Mazza, Manuel Greschek, Rustem Valiullin +2
We present a molecular dynamics study of reentrant nematic phases using the Gay-Berne-Kihara model of a liquid crystal in nanoconfinement. At densities above those characteristic o…
Relaxation of spins due to a magnetic field gradient, revisited; Identity of the Redfield and Torrey theories
R. Golub, Ryan M. Rohm, C. M. Swank
There is an extensive literature on magnetic gradient induced spin relaxation. Cates, Schaefer and Happer (CSH) in a seminal paper, have solved the problem in the regime where diff…
Applications of quantum Monte Carlo methods in condensed systems
Jindrich Kolorenc, Lubos Mitas
The quantum Monte Carlo methods represent a powerful and broadly applicable computational tool for finding very accurate solutions of the stationary Schroedinger equation for atoms…
Surface Polar Phonon Dominated Electron Transport in Graphene
X. Li, E. A. Barry, J. M. Zavada +2
The effects of surface polar phonons on electronic transport properties of monolayer graphene are studied by using a Monte Carlo simulation. Specifically, the low-field electron mo…
Single-ion anisotropy, Dzyaloshinskii-Moriya interaction and negative magnetoresistance of the spin-1/2 pyrochlores R2V2O7
H. J. Xiang, E. J. Kan, M. -H. Whangbo +3
The electronic and magnetic properties of spin-1/2 pyrochlores R2V2O7 were investigated on the basis of density-functional calculations. Contrary to the common belief, the spin-1/2…
Codes and shifted codes of partitions
J. T. Hird, Naihuan Jing, Ernest Stitzinger
In a recent paper, Carrell and Goulden found a combinatorial identity of the Bernstein operators that they then used to prove Bernstein's Theorem. We show that this identity is a s…

Daniel J. Patnaude, Patrick Slane, John C. Raymond +1
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the h…
A latent factor model for spatial data with informative missingness
Brian J. Reich, Dipankar Bandyopadhyay
