The Role of Tidal Interactions and Mergers on the Evolution of Intermediate Redshift Galaxies
(University of Kansas, 2019-12-31)In this work, we present our analysis attempting to constrain the prevalence of tidal interaction and merger (TIM) events on the evolution of intermediate redshift galaxies. The main focus of this work is the effect of ... -
Controlling Interface for Metal-Insulator-Metal Architectures with Ultrathin Dielectric Fabricated Using Atomic Layer Deposition and Sputtering
(University of Kansas, 2019-12-31)The miniaturization of future microelectronics demands the development of high quality ultrathin (few to sub-nm) dielectric films for application in metal-insulator-metal (MIM) architectures. Among all other approaches ... -
Controllable Self-Assembly of Nanostructured Artificial Pinning Centers (APCs) in High Temperature Superconductor Epitaxial Thin Films
(University of Kansas, 2019-08-31)A Superconductor exhibits dc zero-resistance below a critical temperature (Tc). The possible uses of superconductors in a high temperature range of 50-77 K are greatly expanded by the discovery of high temperature ... -
Supernova triggers for end-Devonian extinctions
(National Academy of Sciences, 2020-08-18)The Late Devonian was a protracted period of low speciation resulting in biodiversity decline, culminating in extinction events near the Devonian–Carboniferous boundary. Recent evidence indicates that the final extinction ... -
A study of the propagation of large Barkhausen discontinuities as a function of longitudinal field, circular field, and intensity of magnetization
(University of Kansas, 1933-05-31) -
The optical constants of liquid sodium, liquid sodium amalgams, liquid thallium, and liquid thallium-bismuth alloys
(University of Kansas, 1935-05-31) -
The role of spatial size and orientation of electronic wavefunction in exciton dissociation at van der Waals interfaces
(University of Kansas, 2019-12-31)Organic photovoltaic (OPV) devices are environmental-friendly, lightweight, flexible and inexpensive. However, one of the setbacks for commercial application is its relative low performance in solar to electrical energy ... -
Comprehensive Model of Jupiter's Polar Aurora
(University of Kansas, 2019-05-31)The source of auroral X-ray emission from the Jovian polar caps, whether from electron bremsstrahlung or heavy ion precipitation, has been a topic of debate for the past 40 years, beginning with the Einstein Observatory's ... -
The analysis of angular correlations of radiative transitions and an investigation of excited states of Cl³⁵
(University of Kansas, 1965-05-31) -
Disrupted Pathways: Generating Tunable Macromolecular Assembly Pathways
(University of Kansas, 2018-12-31)What follows is a pathway; a sequence of individual events, which together form a story. Yet it is still only a small part of what has come before. Biological structures also have individual stories; each composed of simple ... -
Bulk and Surface Radio-Frequency Response of Ice
(University of Kansas, 2018-12-31)The flux and cross section of high energy neutrinos is an active area of research. Due to the expected low flux and cross section, interactions are rare and direct detection is ruled out. Large detector volumes with detection ... -
Design, Implementation and First Results of the ANITA-HiCal Experiment
(University of Kansas, 2018-12-31)The ANITA (ANtarctic Impulsive Transient Antenna) experiment is a balloon-borne suite of radio frequency antennas deployed during the austral summers in 2006, 2011, 2014, and 2016 to travel on the circumpolar winds over ... -
Radar detection of cosmic-ray and neutrino induced cascades
(University of Kansas, 2018-12-31)An ultra high energy particle, incident upon the earth, will produce a cascade of particles upon interaction. Detection of this cascade holds the key to understanding the properties of the primary-what it was, how much ... -
Mathematical Modeling of Length Control in the Type III Secretion System
(University of Kansas, 2018-12-31)Type III secretion secretion (T3SS) system is a protein export pathway that helps bacterial cells construct many structures, like the flagellar hook and the injectisome, that aid in crucial physiological processes such as ... -
Topology, Geometry and Morphology of the Dark Matter Web
(University of Kansas, 2018-08-31)Spatial distribution of dark matter displays a variety of intricate three dimensional structures on the largest scales in the Universe, notably the massive haloes, long tubular filaments, flattened walls and the vast ... -
The Lithium Plateau in Super Metal-Rich Stars
(University of Kansas, 2018-08-31)I present a study of the lithium abundances for a sample of super metal-rich (SMR, [Fe/H] > + 0.20) main sequence dwarfs in the solar neighborhood. The SMR stars were selected to have surface temperatures in the region of ... -
Measuring Dijets From Ultra-Peripheral Heavy Ion Collisions
(University of Kansas, 2018-08-31)The Compact Muon Solenoid Experiment measured dijets produced in photon-nuclear collisions using data taken at the Large Hadron Collider in late 2015. Dijet measurements are potentially useful in constraining the gluon ... -
Angular correlations of dijets in ultra-peripheral Pb+Pb collisions at sqrt(s[NN])=5.02 TeV
(University of Kansas, 2018-08-31)One of the most remarkable predictions of the physics of strong interactions, and quantum chromodynamics (QCD) in particular, is gluon saturation. It is observed that the gluon density in hadrons, such as the proton, grows ... -
Charge and Energy Transfer in Different Types of Two-Dimensional Heterostructures
(University of Kansas, 2018-05-31)In the last decade or so, layered materials have attracted significant attention due to their promise for tailoring electronic properties at an atomic level. Individually, these materials have exhibited strong attributes, ... -
Cosmogenic nuclide production within the atmosphere and long period comets
(University of Kansas, 2013-05-31)The Earth is constantly bombarded by cosmic rays. These high energy particles collide with target nuclei, producing a shower of secondary particles. These secondaries contribute significantly to the radiation background ...
