An optical calorimeter for sensitive absorption measurements of non-radiative samples at 4 K was designed, built, and demonstrated. It consists of a cryostat cooled by a commercial pulse tube (PTC) refrigerator, a measurement chamber housing the sample and thermometers, and various fiber-coupled light sources. By employing measures to damp mechanical noise from the environment and active temperature stabilization of critical components of the instrument temperature noise as low as 6 nK/√Hz at 50 mHz was achieved under 15 mW of optical excitation. An optical absorption induced temperature increase of the sample as small as 2.5 nK could be resolved using …

An Improved Method For Spectroscopic Quality Classification, Elizabeth G. Mayer

Mathematics & Statistics ETDs

Spectral quality classification is a vital step in data cleaning before the

analysis of magnetic resonance spectroscopy (MRS) data can be done. This

analysis compares five methods of quality classification; three of these are

legacy methods, Maudsley et al. (2006), Zhang et al. (2018), and

Bustillo et al. (2020), and two newly created methods that used a random forests

classifier (RFC) to inform their classifications. We found that the random forest

classifier was the most accurate at predicting spectra quality (balanced

accuracy for RF of 88% vs legacy of 70%, 72%, or 72%). A

Random-Forests-Informed Filtering method (RFIFM) for quality …

Combining High-Frequency Sensor Data And Nutrient Addition Experiments To Identify Uptake Dynamics In Streams, Justin Rae Nichols

Civil Engineering ETDs

Nutrient enrichment has led to impaired waterways across the globe with an estimated 90% of waterways in the U.S. being negatively impacted from anthropogenic sources. In the past 30 years, there has been significant focus on studying nutrient uptake within fluvial systems. However, there are still critical knowledge gaps about the controls of nutrient dynamics and how these processes scale. This study combined the results from traditional instantaneous nutrient addition experiments and sensor data averaged over ±5 days from the time of addition to determine mechanisms that affect nutrient dynamics in two contrasting streams within the same watershed, over almost …

Socioeconomic And Neuroanatomic Contributions To Language Performance In Children Born Very Preterm At Preschool And School Age, Rebecca E. Avila-Rieger

Psychology ETDs

Background: Children born very preterm are more likely to have difficulties with language acquisition and use that persist throughout childhood. Preterm birth occurs at a critical time in brain development and interrupts neurodevelopment, which has downstream implications for altered neural structure and function. Prematurity and socioeconomic status greatly impact language performance in children, but the neural substrates are poorly understood. Here the neural constituents of language performance are examined in select cortical and subcortical regions.

Methods: Fifty-one children born preterm (24-31 weeks) and 20 born full-term were seen at preschool (mean age = 47 months) and school age (mean age …

Generation Of Correlated Dual Frequency Combs With Pm Fiber Lasers For High-Precision Metrology, Hanieh Afkhamiardakani

Optical Science and Engineering ETDs

Intracavity Phase Interferometry (IPI) using two correlated, counter-propagating frequency combs (pulse trains) in mode-locked lasers has evolved into a powerful technique for high-precision metrology. In this method a physical parameter to be measured imparts a phase shift onto a pulse circulating in the laser cavity. Inside a laser cavity, that phase shift becomes a frequency shift (phase shift/round-trip time) applied to the whole frequency comb created by this pulse as it exits the cavity at each round-trip. This frequency shift is measured by interfering this comb with a reference comb created by a reference pulse circulating in the same mode-locked …

Subjective Cognitive Complaints, Affective Distress, And Objective Cognitive Performance In Mild Traumatic Brain Injury, Brandi Seaman

Psychology ETDs

Background: Traumatic Brain Injury (TBI) is a leading cause of morbidity and mortality among adults in the US (Ma, Chan, & Carruthers, 2014; Raj et al., 2015). According to epidemiological estimates put forth by the CDC, of the 1.7 million TBIs that occur annually in the United States, 80% are mild TBI (mTBI) (Ma, Chan, & Carruthers, 2014). At the sub-acute stage, mTBI patients often report experiencing post-concussion symptoms that include somatic (nausea, headache, dizziness), cognitive (poor attention, memory, and executive function), and behavioral or emotional changes (irritability, depression, emotional lability, anxiety) following their injury (Levin & Diza-Arrastia, 2015).

Plithogenic Cognitive Maps In Decision Making, Florentin Smarandache, Nivetha Martin

Branch Mathematics and Statistics Faculty and Staff Publications

Plithogenic sets introduced by Smarandache (2018) have disclosed new research vistas and this paper introduces the novel concept of plithogenic cognitive maps (PCM) and its applications in decision making. The new approach of defining instantaneous state neutrosophic vector with the confinement of indeterminacy to (0,1] is proposed to quantify the degree of indeterminacy. The resultant vector is obtained by applying instantaneous state vector through the connection matrix together with plithogenic operators comprising the contradiction degrees. The connection matrix is represented as fuzzy matrix and neutrosophic matrix and the resultant vector is determined by applying plithogenic fuzzy operators and plithogenic neutrosophic …

Radiation-Balanced Fiber Lasers And Amplifiers, Esmaeil Mobini Souchelmaei Mr

Optical Science and Engineering ETDs

Over the past decades, high-power fiber lasers and amplifiers have been extensively under research to achieve higher output powers. However, temperature rise in the core of fiber lasers and amplifiers has been a big issue in power-scaling. Radiation-balancing is a viable technique introduced for effective heat mitigation in lasers and amplifiers by S. Bowman in 1995. Radiation-balancing relies on solid-state laser cooling as a self-cooling mechanism to mitigate the generated heat in lasers and amplifiers. To implement the mentioned idea in fiber lasers and amplifiers, a set of issues should be scrutinized; (i) the amenability of silica glass (as the …

Plant Litter Decomposition Differs With Species And Soil Resources In A Chihuahuan Desert Grassland, Andrea Lopez

Biology ETDs

Uncertainties surround the extent to which diversity can mitigate the effects of climate change and anthropogenic activity on ecosystem functions. In desert grasslands, changes to water availability and soil nitrogen, two primary resources that limit ecosystem processes, can have lasting impacts on nutrient cycling. We used grass litter from Bouteloua eriopoda, Bouteloua gracilis, Pleuraphis jamesii, and Sporobolus spp. to assess the effects of soil resources on single- and multi-species decomposition in a Chihuahuan Desert grassland in central New Mexico, USA. Litterbags were deployed in a factorial experiment that manipulated rain pulse size (5- vs. 20-mm) and frequency …

An A Posteriori Error Analysis Of Stationary Incompressible Magnetohydrodynamics, Ari E. Rappaport

Mathematics & Statistics ETDs

Adjoint based a posteriori error analysis is a technique to produce exact error repre- sentations for quantities of interests that are functions of the solution of systems of partial differential equations (PDE). The tools used in the analysis consist of duality arguments and compatible residuals. In this thesis we apply a posteriori error anal- ysis to the magnetohydrodynamics (MHD) equations . MHD provides a continuum level description of conducting fluids in the presence of electromagnetic fields. The MHD system is therefore a multi-physics system, capturing both fluid and electro- magnetic effects. Mathematically, The equations of MHD are highly nonlinear and …

Recruitment To, And Consequences Of, High-Risk Non-Violent Anti-Regime Campaigns In Autocratic Societies: The Egyptian Uprising Of 2011, Marian Azab

Sociology ETDs

This dissertation examines whether the Western-driven model of recruitment to, and consequences of, high-risk activism that McAdam introduced before the internet applies to non-violent anti-regime campaigns in autocratic contexts after the social media revolution. I use the case of the 18-day non-violent Egyptian uprising of 2011 to investigate these topics. I specifically utilize data from the Arab Democracy Barometer survey and other micro- and macro-level sources. I find that face-to-face ties are most effective in recruitment to such movements. Online networks create new forms of dissent, such as online activism. Moreover, online ties are especially useful in mobilizing women. I …

Civil Military Relations Panel, Joshua E. Kastenberg

Faculty Scholarship

In the first week of this month, the nation was surprised to learn that retired general officers (generals and admirals) including James Mattis, Colin Powell, Michael Glenn Mullen, and William McRaven (to name a few) spoke out against President Donald Trump’s response to demonstrations across the United States. President Trump threatened to unilaterally invoke the 1807 Insurrection Act and federalize the National Guard as well as use the active duty Armed Forces of the United States as a “super police force.”

The conduct of the retired generals is not without detractors. The Constitution was constructed with the idea that a …

(SīˈTĭng) Detroit: Vision And Dispossession In A Midwest Bordertown, Matthew J. Irwin

American Studies ETDs

This dissertation examines the relationality of dispossession, racialization, and migration in Detroit, connecting the neoliberal rationality of (re)development to its foundations in Indigenous dispossession and racialized labor. “(Sīˈtĭng) Detroit” understands Detroit as a bordertown, where “the border” is the organizing structure and condition for the operation of settler colonialism in Detroit. From the international boundary to the county line, the border is the on-the-ground, everyday method for controlling space, disciplining populations, and limiting mobility for racialized subjects. To examine possession and belonging in a Black city on an international border, this dissertation introduces a “(sīˈtĭng)” — a methodology for locating …
