A Computational Study of The Electrical Response of Biological Cells with Realistic Three-Dimensional Morphologies
(2021)One of the unique features of a biological cell is the cell membrane that protects the cell interior by establishing a physical barrier between the cytoplasm and the extracellular matrix and governs the distribution of the ... -
A Cubic Spline Projection Method for Computing Stationary Density Functions of Frobenius-Perron Operator
(2022)Stationary density functions of Frobenius-Perron operators have critical applications in many fields of science and engineering. Accordingly, approximating stationary density functions f* is important and the focus of this ... -
A modeling framework for spatial transmission of Covid-19 in local communities
(2022)COVID-19 is the recent infectious disease caused by the severe acute respiratory syndrome novel coronavirus (SARS-CoV-2). Because the transmissibility of the virus is relatively high and the outbreaks remained undetected ... -
A study of carbon and iron charged point defects in gallium nitride: electronic structure implications for high-power photoconductive solid state switch applications
(2021)There is growing demand for high-performance electronics in high volt- age, high current, and high frequency efficiency requirements that current materials (e.g., Si) are not fulfilling. Within the last few years, the ... -
Ab initio calculations of mechanical, thermodynamic and electronic structure properties of mullite, Iota-alumina and boron carbide
(University of Missouri--Kansas City, 2012-05-22)The alumino-silicate solid solution series (Al₄₊₂xSi₂-2xO₁₀-x) is an important class of ceramics. Except for the end member (x=0), Al₂SiO₅ the crystal structures of the other phases, called mullite, have partially occupied ... -
Ab initio computational applications of electronic structure and spectroscopic Properties of bulk Crystalline materials
(2013)Boron-rich compounds and elemental boron have amazing chemical, physical and mechanical properties, but puzzling structures. The uncertain stoichiometric value of foreign elements in boron-rich compounds greatly influences ... -
Ab initio computational applications to complex biomolecular systems
(University of Missouri--Kansas City, 2012-01-17)A series of biomaterial related systems ― including water and DNA molecules ― have been studied using ab initio (first-principles) methods. By investigating the properties of water as the preliminary step, the hydrogen ... -
Ab Initio Study of Amorphous Zeolitic Imidazolate Framework (A-ZIF) and Pyrophosphate crystals
(2020)Zeolitic imidazolate frameworks (ZIFs) are a rapidly emerging class of versatile porous material with many potential applications. Here, we report the construction of an amorphous ZIF (a-ZIF) model from a near-perfect ... -
Addressing On-Chip Power Conversion and Dissipation Issues in Many-Core System-on-a-Chip based on Conventional Silicon and Emerging Nanotechnologies
(University of Missouri -- Kansas City, 2017)Integrated circuits (ICs) are moving towards system-on-a-chip (SOC) designs. SOC allows various small and large electronic systems to be implemented in a single chip. This approach enables the miniaturization of design ... -
Advanced Design and Analysis of UWB U-slot Microstrip Patch Using Theory of Characteristic Modes
(University of Missouri--Kansas City, 2017)Ultra wide band is rapidly advancing as a high data rate wireless communication technology. As is the case in conventional wireless communication systems, an antenna also plays a very crucial role in UWB systems. ... -
Amorphous hydrogenated boron carbide for solid-state direct-conversion thermal neutron detection
(2021)Amorphous hydrogenated boron carbide (a-BC:H) is one of a very limited number of neutron-sensitive materials. It has been studied over the last three decades for solid-state thermal neutron detection due to its high ... -
An Analysis of the Stellar Mass Properties of Distant Galaxy Clusters From the Massive and Distant Clusters of WISE Survey (MaDCoWS)
(2022)The epoch at redshift z ∼ 1 and above is an important one for the study of the evolution of galaxy clusters, as this is the epoch where star formation in clus- ter cores in quenched. Most wide-area cluster surveys at this ... -
An Efficient Heat Engine For Ocean Thermal Energy Conversion
(2022)Carbon-dioxide-absorptive ocean thermal energy conversion (OTEC) holds the promise to provide 2-3 orders of magnitude more energy than current world consumption from fossil fuels, nuclear, hydroelectric, and all other ... -
An Investigation into the Contribution of Hybrid Renewable Energy System to Utility Grid in the Regions with Arid Climate
