Dynamic Recrystallization And Grain Size Effects On Catastrophic Motion Of The Earth’S Mantle During The Flood: Advancement Of Material Models, Heechen Cho, John Baumgardner, Maria Lee, Caleb Miller, Mark Horstemeyer

Proceedings of the International Conference on Creationism

This presentation reports a numerical study to investigate the mechanical effects of dynamic recrystallization (DRX) and the grain size on the speed of flow of rock inside the earth’s solid mantle during the Genesis Flood. The strength, or viscosity, of its constituent minerals is key to understanding and modeling the dynamics of the mantle correctly. A mineral’s strength is strongly influenced by the crystal size, its lattice defects (vacancies and dislocations), and other microscale and crystal-scale phenomena. Since the viscosity difference of the earth’s deep mantle between the present day and during the Flood cataclysm is approximately 10 orders of …

Tapping The Hourglass: Disequilibrium Relaxation Following Accelerated Nuclear Decay, Nathan Mogk

Proceedings of the International Conference on Creationism

In 2005, the Radioisotopes and the Age of The Earth (RATE) research initiative published compelling evidence for at least one episode of past radioactive decay which was accelerated by orders of magnitude compared with the rates measured in recent years. Constancy of radioactive decay rates is a central assumption in radiometric dating. Accelerated nuclear decay (AND) causes systematic change in the results of radiometric dating beyond the in situ above normal accumulation of daughter products. This includes relaxation of magma reservoirs to equilibrium and excessive inheritance arising from disequilibrium excesses of daughter products of greater order than crystal-melt partition ratios. …

Language, Coded Instructions And The Interaction With Thermodynamics, Andy C. Mcintosh

Proceedings of the International Conference on Creationism

The theme of the 9th ICC is Developing and Systematizing the Creation Model of Origins. Following this theme, the proposed paper seeks to establish a rigorous and systematic approach to the important area of information and its interface with the substrate on which the information is expressed. This must first involve the understanding of the laws of thermodynamics not only for isolated systems but for closed (where only energy is allowed to cross the boundary) and open systems (where both matter and energy are allowed to cross the boundary). This is particularly an issue with the second law of …

Cause Of Large Post-Flood Jump In Earth's Carbon 14, D Russell Humphreys

Proceedings of the International Conference on Creationism

Accelerated fusion in the Sun during the flood caused large post-flood jump in Earth’s ¹⁴C

D. Russell Humphreys

Creationists studying carbon-14 dating are generally aware of the need to have a large increase in Earth’s ¹⁴C/C ratio during the post-flood Ice Age (Oard, 2021), from about 0.5% of today’s ratio in fossils (Baumgardner, 2005) to more than 95% of today’s ratio by the time of Moses, 1500 B.C. Today cosmic-ray-generated neutrons hitting ¹⁴N nuclei in the atmosphere produce most of the ¹⁴C. With today’s influx of cosmic rays, it would take about 14,000 years to build …

Genealogical Vs Phylogenetic Mutation Rates: Answering A Challenge, Robert Carter

Proceedings of the International Conference on Creationism

There is a discrepancy between the mutation rate we can measure today and the rate at which evolution is supposed to have proceeded. The former is sometimes called the genealogical mutation rate, for it is obtained by comparing individuals whom we know to be related. The latter is sometimes called the phylogenetic mutation rate. It is calculated by counting the fixed differences between two species and dividing by the estimated time since their common ancestor. Genealogical mutation rates are generally several orders of magnitude faster than phylogenetic estimates. This causes problems for the evolutionary model. For example, using the genealogical …

Human Brain Function Above All Other And The Creation Model, James D. Johansen

Proceedings of the International Conference on Creationism

The human brain functions at a level beyond any other brain in all of creation. With mankind being made in the image of God, there must be signatures of this fact in its design. Modeling the human brain that develops an architectural framework offers the potential to unpack this reality. This premise offers a rich area to explore that expands the creation model to capture the engineering framework God used in creation. This paper will focus on brain neurons and neural networks using systems engineering modeling tools.

The systems modeling language (SysML) will be used to capture a model of …

A Rapid Ice Age And Transition To Ice Sheet Growth, Steven M. Gollmer

Proceedings of the International Conference on Creationism

For the past half-century, creationists have explored different explanations for glacial erosion features across the Northern Hemisphere. The best explanation to date is a single post-flood ice age with multiple surges. The challenge with this model is the limited time available between the end of the Flood and the time of Abraham, which appears to be post ice age. Oard (1979) proposed a short post-flood ice age developing due to warm oceans, volcanic aerosols, and barren surfaces. Performing computer climate simulations, Spelman (1996), Vardiman (1998), Gollmer (2013), and Gollmer (2018) verified that enhance precipitation occurs at higher latitudes due to …

A Model For The Multi-Virus Contact Process, Xu Huang

Rose-Hulman Undergraduate Mathematics Journal

We study one specific version of the contact process on a graph. Here, we allow multiple infections carried by the nodes and include a probability of removing nodes in a graph. The removal probability is purely determined by the number of infections the node carries at the moment when it gets another infection. In this paper, we show that on any finite graph, any positive value of infection rate $\lambda$ will result in the death of the process almost surely. In the case of $d$-regular infinite trees, We also give a lower bound on the infection rate in order for …

Karbala International Journal of Modern Science

In the past decades, many quantum algorithms have been developed. The main obstacle that prevents the widespread implementation of these algorithms is the small size of the available quantum computer in terms of qubits. Blind Quantum Computation (BQC) holds the promise of handling this issue by delegating computation to quantum remote devices. Here, we introduce a novel Constrained Quantum Genetic Algorithm (CQGA) that selects the optimum extreme (minimum or maximum) value of a constrained goal function (or a vast unsorted database) with very low computational complexity. Since the convergence speed to the optimal solution for the Constrained Classical Genetic Algorithm …

On The Origins Of Life — Modelling The Initial Stages Of Complex Coacervate Droplet Formation, Yixuan Wu

Western Libraries Undergraduate Research Awards (WLURAs)

Coacervate droplets are considered a plausible model for protocells due to their spontaneous formation and ability to compartmentalize macromolecules such as nucleic acid and peptides. Although experimental studies have observed and synthesized coacervates under different laboratory conditions, little is known about their structure. Here we present atomistic molecular dynamic simulations of the interactions between water and oppositely charged proteins that cluster together in a salt-dependent process. Observing such liquid-liquid phase separation on an atomic level would serve as a model for the initial stages of complex coacervate formation. Molecular Dynamics was used to compute diagnostics of the structure at different …

Perception Of Nuclear Security As A Barrier To Female Representation In Africa, Primerose Ruhukwa Ms

International Journal of Nuclear Security

Women are strongly underrepresented in the nuclear energy sector, particularly in the field of Nuclear security. Regardless of several government efforts to increase the number of women in this field, which include gender balance polices, education, and awareness campaigns, the nuclear security industry remains a male-dominated field. The reason why nuclear security is shunned by most women in Africa is because of an incorrect perception of what nuclear security is. When a lay person hears the term nuclear, the first thing that comes to mind is nuclear weapons, and many are quick to judge, saying that Africa does not …

K-Long Identification Efficiency Of The Klm Detector In The Belle Ii Experiment Using Splot, Andrew J. Davis, Diptaparna Biswas, Swagato Banerjee

The Cardinal Edge

Long-lived neutral kaon mesons (neutral K-longs) are identified by energy deposits in the KLM detector of the Belle II experiment. However, various other particles can also deposit energy in the KLM detector. A statistical method known as sPlot can be utilized to distinguish between the energy deposit patterns of neutral K-longs vs. other backgrounds. This technique, currently developed with Monte-Carlo events, allows for a more robust determination of K-long identification efficiency in the KLM detector, which can eventually be applied on real data.
