Intel Concurrent Collections as a Method for Parallel Programming
(2011)Computer hardware has become parallel in order to run faster and more efficient. One of the current standard parallel coding libraries is MPI (Message Passing Interface). The Intel Corporation is developing a new parallel ... -
Species tree inference in a recent radiation of orioles (Genus Icterus): Multiple markers and methods reveal cytonuclear discordance in the northern oriole group
(Elsevier Inc., 2011-06-26)Recent computational advances provide novel opportunities to infer species trees based on multiple independent loci. Thus, single gene trees no longer need suffice as proxies for species phylogenies. Several methods have ... -
Pathway networks generated from human disease phenome
(BMC Medical Genomics, 2018-09-14)Background: Understanding the effect of human genetic variations on disease can provide insight into phenotype-genotype relationships, and has great potential for improving the effectiveness of personalized medicine. While ... -
A GPU Memory System Comparison for an Elliptic Test Problem
This paper presents GPU-based solutions to the Poisson equation with homogeneous Dirichlet boundary conditions in two spatial dimensions. This problem has well-understood behavior, but similar computation to many more ... -
Congruence between nuclear and mitochondrial DNA: Combination of multiple nuclear introns resolves a well-supported phylogeny of New World orioles (Icterus)
(Elsevier Inc., 2010-07)Darwin’s vision of a “Tree of Life” showing evolutionary relationships among all extant species seems an increasingly feasible goal, at least for vertebrate animals. However, virtually all published molecular phylogenies ... -
Informational Requirements for Transcriptional Regulation
(2014-05-01)Transcription factors (TFs) regulate transcription by binding to specific sites in promoter regions. Information theory provides a useful mathematical framework to analyze the binding motifs associated with TFs but imposes ... -
FEM Convergence for PDEs with Point Sources in 2-D and 3-D
(2015)Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in ... -
Multigrid preconditioning of linear systems for semismooth Newton methods applied to optimization problems constrained by smoothing operators
(Taylor and Francis Online, 2013-11-07)This article is concerned with the question of constructing effcient multigrid preconditioners for the linear systems arising when applying semismooth Newton methods to large-scale linear-quadratic optimization problems ... -
Shortwave direct radiative effects of above-cloud aerosols over global oceans derived from 8 years of CALIOP and MODIS observations
(Copernicus Publications on behalf of the European Geosciences Union, 2016-03-04)In this paper, we studied the frequency of occurrence and shortwave direct radiative effects (DREs) of above-cloud aerosols (ACAs) over global oceans using 8 years (2007–2014) of collocated CALIOP and MODIS observations. ... -
An Implementation of Binomial Method of Option Pricing using Parallel Computing
The Binomial method of option pricing is based on iterating over discounted option payoffs in a recursive fashion to calculate the present value of an option. Implementing the Binomial method to exploit the resources of a ... -
Surface Modification at Nanoscale; Nanoparticle-Nanowire Transition
(2018-04-15)Binary, ternary and quaternary oxides and selenides have been developed and used in multiple applications including high power lasers, detectors, dielectric energy storage and variety of optical devices. These materials ... -
Implementing a Numerical Package to Model Collective Cell Migration
(2014-01-27)In this article we present our three dimensional mathematical model of collective cell migration and describe the method by which we developed and implemented this package on the High Performance Computing Facility at UMBC. ... -
Characterization of the SOS meta-regulon in the human gut microbiome
(Oxford University Press, 2014-01-08)Motivation: Data from metagenomics projects remain largely untapped for the analysis of transcriptional regulatory networks. Here, we provide proof-of-concept that metagenomic data can be effectively leveraged to analyze ... -
Comparison of Performance Analysis Tools for Parallel Programs Applied to CombBLAS
(2015)Performance analysis tools are powerful tools for high performance computing. By breaking down a program into how long the CPUs are taking on each process (pro- filing) or showing when events take place on a timeline over ... -
Parallelization for Fast Image Reconstruction using the Stochastic Origin Ensemble Method for Proton Beam Therapy
(2015)Proton beam therapy is becoming increasingly common in the eld of cancer treatment because of the advantages over other forms of radiation therapy. These advantages arise from the nite range of the proton beams, the ... -
Third-Order Nonlinear Optical Properties of ALD Grown TiO₂ Films by Thermally Managed Z-scan Method
(Optical Society of America, 2018)Thermally managed Z-scan performed on ALD grown TiO₂ films demonstrated n₂ values of 1.7×10⁻¹¹ and 1.94 × 10⁻¹⁰cm²/W for films grown at 100°C and 250°C, respectively – greater than 1000X that of other growth methods. -
Statistical Analysis of a Case-Control Alzheimer's Disease: A Retropective Approach with Su cient Dimension Reduction
(2015)Alzheimer's Disease is a neurological disorder chiefly present in the elderly that affects functions of the brain such as memory and logic, eventually resulting in death. There is no known cure to Alzheimer's and evidence ... -
Assessing Climate Impacts on Regional Water Resources in the Midwestern US
(2015)It is well documented that decadal climate variability (DCV) has a signi cant impact on water resources in the Missouri River Basin (MRB). This project aims to utilize multi-decadal simulations of Global Climate Models ...
