A New Error Analysis For Finite Element Methods For Elliptic Neumann Boundary Control Problems With Pointwise Control Constraints, Susanne C. Brenner, Li Yeng Sung

Faculty Publications

We present a new error analysis for finite element methods for a linear-quadratic elliptic optimal control problem with Neumann boundary control and pointwise control constraints. It can be applied to standard finite element methods when the coefficients in the elliptic operator are smooth and also to multiscale finite element methods when the coefficients are rough.

Beyond Water Surface Profiles: A New Iterative Methodology For 2d Model Calibration In Rivers Using Velocity Data From Multiple Cross-Sections, Fabian Rivera-Trejo, Gabriel Soto-Cortes, Kory M. Konsoer, Eddy J. Langendoen, Gaston Priego-Hernandez

Faculty Publications

Observed longitudinal water-surface profiles are commonly used to calibrate river hydrodynamic models, relying on assumptions of lateral uniformity in water surface elevation and velocity distribution. While suitable for 1D models, this approach has limitations in regard to 2D model calibration. When 2D flow measurements are available, a more robust quantitative evaluation is necessary to assess model accuracy. This study introduces a novel methodology to improve 2D model calibration and evaluate performance. High-resolution bathymetric and hydrodynamic data collected with a multibeam echosounder (MBES) and acoustic Doppler current profiler (ADCP) were aligned to compare observed and simulated flow velocities at matching spatial …

Earliest Ancient Maya Salt Production In Southern Belize: Excavations At Jay-Yi Nah, Heather Mckillop, E. Cory Sills

Faculty Publications

Salt works along the Yucatan coasts of Mexico and Belize provide a record of salt production for inland trade during the height of Late Classic Maya civilisation (AD 550-800). At the Paynes Creek Salt Works in Belize, production focused on the creation of salt cakes by boiling brine in pots supported over fires in dedicated salt kitchens. Underwater excavations at the Early Classic (AD 250-550) site of Jay-yi Nah now indicate there was a longer and evolving tradition of salt making in the area, one that initially employed large, incurved bowls to meet local or down-the-line trade needs before inland …

Effects Of Immigration On Native Entrepreneurship In The Us: An Analysis Of Self-Employment Over 1980–2018, Bulent Unel

Faculty Publications

This paper examines the causal impact of immigration on entrepreneurship among US-born non-Hispanic whites in non-agricultural private sectors from 1980 to 2018. Using self-employment as a proxy for entrepreneurship and distinguishing between incorporated individuals and unincorporated self-employed workers, I find a sizable negative impact of immigration on native self-employment. Importantly, this effect is consistent across incorporated and unincorporated self-employment and remains robust across demographic groups based on gender, age, and education. Results are robust to the choice of controls and estimation methods.

Ceres: Organic-Rich Sites Of Exogenic Origin?, R. Sarkar, A. Nathues, M. Hoffmann, E. Cloutis, K. Mengel, P. Singh, G. Thangjam, J. Hernandez, S. Karunatillake, M. Coutelier

Faculty Publications

Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara craters. The origin of organics, either endogenic or exogenic, in these fresh exposures is still under debate. This study addresses the origin of the organics by analyzing their global distribution and geologic context. Our first step involved a global search for organic-rich sites that might have escaped previous detections. We achieved this by using a deep neural network, utilizing spectral …

Trans-Crustal Magmatic Processes Revealed By Amphibole Breakdown Textures At The Quillacas Monogenetic Volcanic Center, Bolivia, L. C. Velázquez Santana, C. L. Mcleod, B. Shaulis, M. Loocke, R. Al Gbory

Faculty Publications

Amphibole exerts a fundamental control on arc magma petrogenesis, differentiation, and the long-term evolution of the arc crust. This study identifies two texturally distinct amphibole populations within andesitic lavas and entrained hornblendite cumulates at the Quillacas monogenetic volcanic center in the Eastern Altiplano, Bolivia. Within the hornblendites, all amphiboles are tschermakitic, large (≤800 μm) with thick, granular reaction rims (avg. 27 μm thickness). In the host andesites, tschermakites are also the dominant amphibole species but are smaller (250–400 μm) with thin, symplectic reaction rims (avg. 7–9 μm thickness). An intergrowth of symplectic and granular reaction rims is also observed in …

Irrigation And Society In The Upper Río Grande Basin, U.S.A: A Heritage Of Mutualism, José A. Rivera Ph.D

Faculty Publications

The acequias of the upper Río Grande are more than just irrigation canals. They also allocate and manage water for the community of landowners in the system. After four centuries of use, the acequias persist into modern times with their founding principles intact: self-government, local autonomy, internal rules for operating procedures, and a strong sense of mutualismo or communal responsibility. They have endured since Spanish colonial settlement and have maintained continuity of a water culture surviving political-administrative changes under three sovereigns, Spain (1598-1821), Mexico (1821-1848), and the United States (1848-Present). Despite stressors of climate variability, demographic changes, urbanization, and economic …

Pilot Study: Initial Investigation Suggests Differences In Emt-Associated Gene Expression In Breast Tumor Regions, Kylie L. King, Hamed Abdollahi, Zoe Dinkel, Alannah Akins, Homayoun Valafar, Heather Dunn

Faculty Publications

Triple negative breast cancer (TNBC) is the most aggressive subtype and disproportionately affects African American women. The development of breast cancer is highly associated with interactions between tumor cells and the extracellular matrix (ECM), and recent research suggests that cellular components of the ECM vary between racial groups. This pilot study aimed to evaluate gene expression in TNBC samples from patients who identified as African American and Caucasian using traditional statistical methods and emerging Machine Learning (ML) approaches. ML enables the analysis of complex datasets and the extraction of useful information from small datasets. We selected four regions of interest …

Predicting Individual Long-Term Prognosis Of Spatial Neglect Based On Acute Stroke Patient Data, Lisa Röhrig, Daniel Wiesen, Dongyun Li, Chris Rorden, Hans-Otto Karnath

Faculty Publications

One of the most pressing questions after a stroke is whether an individual patient will recover in the long term. Previous studies demonstrated that spatial neglect—a common cognitive deficit after right hemispheric stroke—is a strong predictor for poor performance on a wide range of everyday tasks and for resistance to rehabilitation. The possibility of predicting long-term prognosis of spatial neglect is therefore of great relevance. The aim of the present study was to test the prognostic value of different imaging and non-imaging features from right hemispheric stroke patients: individual demographics (age, sex), initial neglect severity and acute lesion information (size, …

Population Variability Across Geographical Ranges: Perspectives And Challenges, Cleber Ten Caten, Tad Dallas

Faculty Publications

Populations fluctuate over time and across geographical space, and understanding how different factors contribute to population variability is a central goal in population ecology. There is a particular interest in identifying trends of population variability within geographical ranges as population densities of species can fluctuate substantially across geographical space. A common assumption is that populations vary more near species geographical range edges because of unsuitable environments and higher vulnerability to environmental variability in these areas. However, empirical data rarely support this expectation, suggesting that population variability is not related to its position within species geographical ranges. We propose that performance …

Simulations Of Attosecond Metallization In Quartz And Diamond Probed With Inner-Shell Transient Absorption Spectroscopy, Lucas Kurkowski, Adonay Sissay, Mengqi Yang, Alexander Meyer, Kenneth Lopata

Faculty Publications

When dielectrics are hit with intense infrared (IR) laser pulses, transient metalization can occur. The initial attosecond dynamics behind this metallization are not entirely understood. Therefore, simulations are needed to understand this process and to help interpret experimental observations of it, such as with attosecond transient absorption (ATA). In this paper, we present first-principles simulations of ATA based on bulk-mimicking clusters and real-time time-dependent density functional theory (RT-TDDFT), with Koopmans-tuned range-separated hybrid functionals and Gaussian basis sets. Our method gives good agreement with the experiment for the breakdown threshold in silica and diamond. This breakdown voltage corresponds to a Keldysh …
