Alternative Methods for Ultrasonic Welding of Advanced Thermoplastic Composites
(2023-03-01)The fusion bonding of advanced thermoplastic composites has a variety of applications in aerospace, automotive, medical, consumer electronics and energy markets. High-power ultrasonic welding is a state-of-the-art manufacturing ... -
Surveying Features of Spherical Viruses
(2023-01-01)The main research goal was to investigate the relationship between gauge points and other capsid properties. Data was collected from online databases: ViperDB (VIrus Particle ExploreR database), RCSB (Research Collaboratory ... -
Synthesis & Characterization of Entropy Stabilized YBCO Superconductors
(2023-01-01)The nuanced causes of the ability of certain materials to obtain superconductivity, or zero resistance, are still a topic of debate. To further developments in this area of study, the synthesis and characterization of novel ... -
Determinant Quantum Monte Carlo simulations of charge density waves in the Holstein model with a double well potential
(2022-11-01)This work is concerned with transitions to the ordered charge density wave (CDW) phase. CDWs are well studied, but there is still more to explore, especially as they relate to superconductivity. In some instances, CDWs are ... -
Using Point Arrays to Characterize Drug-Bound Hepatitis B Virus and Human Enterovirus 71 Capsid Structures
(2021-11-01)A virus capsid is composed of identical protein subunits which occupy chemically equivalent environments and assemble according to icosahedral symmetry. This protein shell holds critical roles throughout the viral life ... -
Investigation into the causes of degrading radio signals during Geomagnetic Storms
(2022-02-25)The release of solar winds from the sun has drastic effects on the Earth’s geomagnetic field and the Ionosphere. GPS navigation uses radio signals that travel from a satellite to a ground receiver, passing through the ... -
Quantifying the Characteristics of Viruses in the Leviviridae Family Using Icosahedral Point Arrays
(2022-06-01)Point arrays provide a neat method for structural comparison between viruses by highlighting different aspects of the viral capsid. For very structurally similar viruses, using multiple point array fits instead of just the ... -
Point Array Study of Antibody Binding in Viruses
(2022-06-01)To combat viral infections, organisms with adaptive immune systems have developed antibodies that can neutralize or render viruses as non-infectious. This can be done in multiple fashions. The primary way to stop the ... -
Sustainable Irrigation in the Developing World
(2022)This SIP analyzes an application of physical theories to the design of a sustainable irrigation system like the one constructed in the village of Pawaga. Unlike most physics SIPs whose subject matter is supported by organized ... -
Investigations into the tunneling magnetoresistance effects in thin films of (La1−yPry)1−xCaxMnO3
(2022)Thin lms of (La1−yPry)1−xCaxMnO3 (LPCMO) are known to undergo phase separation between a ferromagnetic metallic (FMM) phase and a charged-ordered insulator (COI) phase. When cooled down from room temperature to achieve ... -
Compactness of Icosahedral Viruses Reveals High Mass Packing of Protruding Features
(2021-06-01)A method of studying viral protein design was developed to describe the distribution of mass throughout viral capsid proteins. Protein compactness was measured using an interparticle distance measurement and a capsid ... -
6-D Lattice Phase Transformations in Viral Maturation
(2021-06-01)In this paper we will show how to use the fundamentals of the math of quasi-crystallography to model the maturation of viral capsids. Viruses have had a deep influence on the evolution of life, with traces of this influence ... -
Utilizing Point Arrays to Further Classify Spherical Viruses Exhibiting Icosahedral Symmetry
(2019-07-01)Triangulation number is crucial for understanding the size of viral capsids and total number of proteins, but lacks in its ability to describe the conformational changes that occur throughout the maturation phase of spherical ... -
Exploring TaS2 and YBa2Cu3O7-δ : Exotic Materials of Physics
(2019-09-01)Methods of measurement of TaS2 (Tantrum Disulfide) and YBa2Cu3O7-δ (Yttrium Barium Copper Oxide) samples to reveal their physical properties and introduce the physical models producing their characteristics were explored ... -
Decomposition of Virus Normal Modes into Spherical Harmonics An Exploration of Symmetry Adapted Functions (SAFs)
(2020-02-13)The normal modes for viruses, in which all of its atoms are oscillating at the same frequency, can be thought of as a very complicated system of masses and springs. Each atom has its own mass, and the bonds between atoms ... -
Plasma Wave Observations During Geomagnetic Storms with MMS
(2020-04-01)During magnetic storms, the Earth’s atmosphere loses enhanced amounts of oxygen which escapes to the magnetosphere. In space, governed by the Earth’s magnetic field, these oxygen ions gyrate around magnetic field lines and ... -
Growth and Characterization of Fe-Se-Te Superconducting Materials
(2019-12-01)Iron-based superconductors are a family of high temperature superconductors which are not explained by the standard BCS theory. We have synthesized Fe-Se-Te single crystals via AlCl3 and KCl flux under a temperature gradient. ... -
Introduction to Computational Models of Synaptic Plasticity
(2017)The function of memorizing of a brain is basically due to synaptic plasticity. Ca2+ and dopamine inputs can lead to change in activity of AMPAR, through phosphorylation and dephosphorylation pathways. This process consists ... -
