### Recent Submissions

• #### Photoluminescence quantum efficiency of Er optical centers in GaN epilayers ﻿

(Springer Nature, 2017-01-05)
We report the quantum efficiency of photoluminescence processes of Er optical centers as well as the thermal quenching mechanism in GaN epilayers prepared by metal-organic chemical vapor deposition. High resolution infrared ...
• #### Epitaxial thin films of pyrochlore iridate Bi2+xIr2-yO7-delta: structure, defects and transport properties ﻿

(Springer Nature, 2017-08-10)
While pyrochlore iridate thin films are theoretically predicted to possess a variety of emergent topological properties, experimental verification of these predictions can be obstructed by the challenge in thin film growth. ...
• #### Shorter Exposures to Harder X-Rays Trigger Early Apoptotic Events in Xenopus laevis Embryos ﻿

(PLOS, 2010-01-29)
Background A long-standing conventional view of radiation-induced apoptosis is that increased exposure results in augmented apoptosis in a biological system, with a threshold below which radiation doses do not cause any ...

(PLOS, 2012-11-26)
We study the standard SIS model of epidemic spreading on networks where individuals have a fluctuating number of connections around a preferred degree. Using very simple rules for forming such preferred degree networks, ...
• #### Correlations and Scaling Laws in Human Mobility ﻿

(PLOS, 2014-01-13)
Background In recent years, several path-breaking findings on human mobility patterns point out a novel issue which is of important theoretical significance and great application prospects. The empirical analysis of the ...
• #### Cascading Walks Model for Human Mobility Patterns ﻿

(PLOS, 2015-04-10)
Background Uncovering the mechanism behind the scaling laws and series of anomalies in human trajectories is of fundamental significance in understanding many spatio-temporal phenomena. Recently, several models, e.g. ...
• #### A model of risk and mental state shifts during social interaction ﻿

(PLOS, 2018-02-15)
Cooperation and competition between human players in repeated microeconomic games offer a window onto social phenomena such as the establishment, breakdown and repair of trust. However, although a suitable starting point ...
• #### Quanta 2017/2018 ﻿

(Virginia Tech, 2018)
A publication for the faculty, staff, students, alumni, emeriti & friends of the Department of Physics at Virginia Tech.
• #### Modulation of nucleosomal DNA accessibility via charge-altering post-translational modifications in histone core ﻿

(2018-03-16)
Abstract Background Controlled modulation of nucleosomal DNA accessibility via post-translational modifications (PTM) is a critical component to many cellular functions. ...
• #### Systematic uncertainties in long-baseline neutrino-oscillation experiments ﻿

(Iop Publishing Ltd, 2017-05-01)
• #### Using L/E Oscillation Probability Distributions ﻿

This paper explores the use of $L/E$ oscillation probability distributions to compare experimental measurements and to evaluate oscillation models. In this case, $L$ is the distance of neutrino travel and $E$ is a measure ...
• #### Improved Search for $\bar ν_μ\rightarrow \bar ν_e$ Oscillations in the MiniBooNE Experiment ﻿

The MiniBooNE experiment at Fermilab reports results from an analysis of ¯νe appearance data from 11.27 × 10²⁰ protons on target in antineutrino mode, an increase of approximately a factor of two over the previously reported ...
• #### Improved measurement of neutral current coherent pi(0) production on carbon in a few-GeV neutrino beam ﻿

(Amer Physical Soc, 2010-06-16)
• #### Measurement of single charged pion production in the charged-current interactions of neutrinos in a 1.3 GeV wide band beam ﻿

(Amer Physical Soc, 2008-08-01)
• #### Measurement of the quasielastic axial vector mass in neutrino interactions on oxygen ﻿

(Amer Physical Soc, 2006-09-01)
• #### Search for coherent charged pion production in neutrino-carbon interactions ﻿

(Amer Physical Soc, 2005-12-16)
• #### Evidence for muon neutrino oscillation in an accelerator-based experiment ﻿

(American Physical Soc, 2005-03-04)
• #### Probing electron-argon scattering for liquid-argon based neutrino-oscillation program ﻿

The electron scattering has been a vital tool to study the properties of the target nucleus for over five decades. Though, the particular interest on $^{40}$Ar nucleus stemmed from the progress in the accelerator-based ...
• #### Disordered Supersolids in the Extended Bose-Hubbard Model ﻿

(Nature, 2017-10-06)
The extended Bose-Hubbard model captures the essential properties of a wide variety of physical systems including ultracold atoms and molecules in optical lattices, Josephson junction arrays, and certain narrow band ...
• #### Quanta 2015/2016 ﻿

(Virginia Tech, 2016)
A publication for the faculty, staff, students, alumni, emeriti & friends of the Department of Physics at Virginia Tech.
