• #### Models for metal-poor stars with enhanced abundances of C, N, O, Ne, Na, Mg, Si, S, Ca, and Ti, in turn, at constant helium and iron abundances ﻿

(IOP Publishing, 2012-08-10)
Recent work has shown that most globular clusters have at least two chemically distinct components, as well as cluster-to-cluster differences in the mean [O/Fe], [Mg/Fe], and [Si/Fe] ratios at similar [Fe/H] values. In ...
• #### Models of metal-poor stars with different initial abundances of C, N, O, Mg, and Si. I. Bolometric corrections derived from new MARCS synthetic spectra and their implications for observed colour-magnitude diagrams ﻿

(Oxford University Press, 2021-11-04)
New, high-resolution MARCS synthetic spectra have been calculated for more than a dozen mixtures of the metals allowing, in turn, for variations in C:N:O, [CNO/Fe], and enhanced abundances of C, O, Mg, and Si. Bolometric ...
• #### Models of parenting and its effect on academic productivity: Preliminary results from an international survey ﻿

(International Conference on Scientometrics and Informetrics, 2019-09)
This preliminary paper investigates the cost of parenting engagement on academic productivity and impact. Instead of investigating the relationship between gender and academia, this study focuses on time invested in parenting ...
• #### Modules for the investigation of the central fan question through numerical computation ﻿

(Wichita State University, 2015-05)
In this thesis, we continue the research of investigating the central fan question through numerical computation of minimal surfaces and the author develops a new conformal map in hopes of producing a more accurate and ...
• #### Monochromatic molecular absorption coefficients for use in calculations of stellar opacity ﻿

(Wichita State University, 2018-05)
In order to fully understand stellar structure, it is necessary to know the opacity, as it influences the behavior of radiative transfer within the stellar interior. Opacity plays an important role in the onset of ...

In order to fully understand stellar structure, it is necessary to know the opacity, as it influences the behavior of radiative transfer within the stellar interior. Opacity plays an important role in the onset of convection ...
• #### Monte Carlo simulations of a near-solar orbit neutrino detector ﻿

(Wichita State University, 2019-05)
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 experiments ...

• #### 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 ...
