Monte Carlo simulations of a near-solar orbit neutrino detector
(Wichita State University, 2019-04-26)Neutrinos -- weakly interacting subatomic particles often resultant of nuclear processes, including hydrogen fusion -- are the only direct insight into the core of the Sun. Previously constructed neutrino detection ... -

Monte Carlo simulations of a space-based dark matter detector
(Wichita State University, 2021-05)It has been well established that a large percentage of the material in the universe is in an undiscovered form; Dark Matter. Most of this material is gravitationally condensed together as galaxies and clusters of galaxies. ... -
Mossbauer and magnetization studies of nickel ferrite nanoparticles synthesized by the microwave-combustion method
(ELSEVIER SCIENCE BV, 2013-10)Nanocrystalline nickel ferrite was synthesized from its stoichiometric metal nitrates and urea mixtures, using a microwave assisted combustion method. The process was a convenient, inexpensive and an efficient method for ... -
Mossbauer investigations in hematite nanoparticles
(AMG Transcend Association, 2021-10-16)Hematite nanoparticles of average size 20 nm were synthesized using the sol-gel method, and the structural characterizations were conducted using XRD and TEM. The XRD profile revealed a small fraction of the maghemite ... -
The multi-layer free boundary problem for the p-Laplacian in convex domains
(European Mathematical Society, 2004-08-21)The main result of this paper concerns existence of classical solutions to the multi-layer Bernoulli free boundary problem with nonlinear joining conditions and the p-Laplacian as gov- erning operator. The present treatment ... -
Multi-scale phase-field modeling of layer-by-layer powder compact densification during solid-state direct metal laser sintering
(Elsevier, 2021-05-01)Solid-state direct metal laser sintering (S-DMLS) builds structures by using laser energy to sinter powder particles in a layer-by-layer manner. Powder size distribution (PSD) is an important parameter governing the ... -
Multifractional vector Brownian motions, their decompositions, and generalizations
(Taylor & Francis Group, 2015-05-04)This article introduces three types of covariance matrix structures for Gaussian or elliptically contoured vector random fields in space and/or time, which include fractional, bifractional, and trifractional vector Brownian ... -
Multiqubit entanglement of a general input state
(Rinton Press, Inc., 2013-01)Measurement of entanglement remains an important problem for quantum information. We present the design and simulation of an experimental method for an entanglement indicator for a general multiqubit state. The system can ... -
Multivariate isotonic regression and its algorithms
(Wichita State University, 2009-05)We use regression functions, which are the means of random variables, to interpret statistical inference. Often an order is imposed on the values of the regression function. Thus, we refer to the regression as an order ... -

Neutrino detector design, attenuation studies, and testing for the νSol project
(Wichita State University, 2020-05)In order to further work on the Sol project funded through a NASA Phase II NIAC grant, I have performed detailed simulations on the effect of attenuation length on the performance of the Sol solar neutrino probe using ... -
Neutrino interaction classification with a convolutional neural network in the DUNE far detector
(American Physical Society, 2020-11-09)The Deep Underground Neutrino Experiment is a next-generation neutrino oscillation experiment that aims to measure CP-violation in the neutrino sector as part of a wider physics program. A deep learning approach based on ... -
New constraints on oscillation parameters from $ν_e$ appearance and $ν_μ$ disappearance in the NOvA experiment
(American Physical Society, 2018-08-24)We present updated results from the NOvA experiment for $\nu_\mu\rightarrow\nu_\mu$ and $\nu_\mu\rightarrow\nu_e$ oscillations from an exposure of $8.85\times10^{20}$ protons on target, which represents an increase of 46% ... -
A new test for decreasing mean residual lifetimes
(Taylor & Francis, 2018-03-02)The mean residual life of a non negative random variable X with a finite mean is defined by M(t) = E[X - t|X > t] for t 0. One model of aging is the decreasing mean residual life (DMRL): M is decreasing (non increasing) ... -
A new test for new better than used in expectation lifetimes
(Taylor & Francis Group, 2015)The mean residual life of a non negative random variable X with a finite mean is defined by M(t) = E[X - t | X > t] for t >= 0. A popular nonparametric model of aging is new better than used in expectation (NBUE), when ... -
Nilsolitons of H-type in the Lorentzian setting
(Houston Journal of Mathematics, 2015)It is known that all left-invariant pseudo-Riemannian metrics on the three-dimensional Heisenberg group H-3 are algebraic Ricci solitons. We consider generalizations of Riemannian H-type, namely pseudoH-type and pH-type. ... -
