Experimental Studies Of Fundamental Aspects Of Auger Emission Process In Cu(100) And Ag(100)
(Physics, 2014-09-17)
Auger spectra at the low energies are accompanied by large contributions unrelated to the Auger transition. The Auger unrelated contributions can obscure the Auger peak and affect the quantitative analysis of the materials ...
The Variations Of Geomagnetic Energy And Solar Irradiance And Their Impacts On Earth's Upper Atmosphere
(Physics, 2014-03-10)
The primary energy sources of Earth's upper atmosphere are the solar irradiance and geomagnetic energy including Joule heating and particle precipitation. Various data and models are utilized to investigate the variations ...
First Principles Computational Modeling Of The Surface Properties Of Uranium Dioxide
(Physics, 2014-07-14)
The interaction of uranium dioxide (UO₂) with environmental elements occurs at its exposed surface and a fundamental understanding of this interaction process begins at the atomic scale. In this regard, atomic scale ...
Orbital Stability Analysis And Chaotic Dynamics Of Exoplanets In Multi-stellar Systems
(Physics, 2014-12)
The advancement in detection technology has substantially increased the discovery rate of exoplanets in the last two decades. The confirmation of thousands of exoplanets orbiting the solar type stars has raised new ...
Cutoff Frequencies For Alfven Waves In The Solar Atmosphere
(Physics, 2014-12)
Propagation of linear Alfven waves in the isothermal and non-isothermal solaratmosphere is investigated numerically and analytically. It is shown that thetwo wave variables, the velocity and magnetic field perturbations, ...
Investigating The Global Geospace Response To A Period Of Solar Wind High Speed Streams Using The Lyon-Fedder-Mobarry MHD Simulation
(Physics, 2014-12)
As the solar wind flows past the Earth, it interacts with the Earth's magnetic field and transfers energy and momentum to the geospace environment. During times when the solar cycle is near a minimum, there is a tendency ...
Evidence Of A Positron Bound State On The Surface Of A Topological Insulator
(Physics, 2014-12)
We describe experiments aimed at probing the sticking of positrons to the surfaces of topological insulators performed at university of Texas at Arlington using the Positron Annihilation induced Auger electron Spectrometer. ...
Biological Damage Of UV Radiation In Environments Of F-type Stars
(Physics, 2014-07-14)
I investigate the general astrobiological significance of F-type main-sequence stars with special consideration to stellar evolutionary aspects due to nuclear evolution. DNA is taken as a proxy for carbon-based macromolecules ...
Phenomenological Studies Of Dark Matter
(Physics, 2014-07-14)
It is common knowledge that eighty percent of the matter in our Universe consists of a mysterious substance called ``dark matter'' (DM) which has only been detected through its gravitational interactions. The ``Standard ...
