Assessing Visual Function In Young And Medically Complex Children With Cerebral Visual Impairment, Kathleen Mary Weden

All ETDs from UAB

Cerebral Visual impairment (CVI) has become the leading cause of vision impairment in children worldwide. Early identification of CVI has been shown to improve visual function outcomes and improve developmental outcomes and quality of life. However, children with CVI are difficult to identify and assess because the medical conditions that cause CVI can also cause impairment across domains of function. A scoping review was first conducted on interventions and outcome measures used for children with CVI. The sources identified (n=20) were grouped into five types of interventions. The review confirmed the need for quantitative, standardized methods for measuring visual function …

Mechanisms Linking The Circadian Clock To Cardiac Physiology, Lamario J. Williams

All ETDs from UAB

Rationale: Cardiovascular disease continues to be the leading cause of death in America. Many aspects of both cardiovascular physiology (e.g., blood pressure, heart rate) and pathophysiology (e.g., myocardial infarctions, sudden cardiac death) exhibit time-of-day dependent fluctuations (termed diurnal variations). Circadian clocks consist of transcriptional feedback cascades directly modulating expression of genes involved in processes such as metabolism, signaling, and ion transport. Interestingly, genetic deletion of a core circadian clock component in the heart (cardiomyocyte-specific Bmal1 knockout mice) leads to chronic induction of the transcriptional repressor E4 Promoter-Binding Protein 4 (E4BP4) associated with early-onset dilated cardiomyopathy, metabolic inflexibility, and electrophysiologic disturbances. …

Evaluation Of A Hospital Pdmp Ehr-Integration Implementation: A Mixed, Heather D. Martin

All ETDs from UAB

Background: Many providers continue to over prescribe opioids for pain, and Prescription Drug Monitoring Programs (PDMP) can be used as a tool to assist with appropriate opioid prescribing decisions. Despite mandates requiring opioid prescribers to review patients’ prescribing history in their state’s PDMP, barriers to PDMP success still exist such as a difficult PDMP logon process and having to log on to a separate PDMP system, which can cause access, workflow, time commitment, and ease of use issues and deter providers from using the PDMP. Some health care organizations have implemented PDMP electronic health record (EHR) integration (PDMP EHR-integration) to …

Spectroscopic And Electrical Characterization Of Cr:Al:Znse Gain Elements, Rick Harrington Watkins

All ETDs from UAB

Middle infrared (mid-IR) lasers have gained significant attention across various fields, including optics research, medical applications, and defense technologies. The mid-IR spectral region, spanning wavelengths between 2μm and 8μm, is particularly important due to its overlap with the molecular fingerprints, which enables the detection of organic and inorganic molecules through their rotational and vibrational frequencies. Transition metaldoped II-VI (TM:II-VI) chalcogenides, specifically Cr:ZnSe, are well-known laser materials for optically pumped mid-IR lasers, offering effective lasing capabilities in this spectral range. In addition to optical excitation, the wide-band semiconductor nature of Cr:ZnSe crystals holds the potential for direct electrical excitation, making them …

Interactions Between Pseudomonas Aeruginosa And The Oral Commensal Streptococcus Salivarius, Sara Noelle Stoner

All ETDs from UAB

The cystic fibrosis airway is a polymicrobial environment often dominated by opportunistic pathogens such as Pseudomonas aeruginosa, a leading cause of lung function decline and mortality in persons with CF. Commensal streptococcal colonization has been associated with stable CF lung function in multiple studies. However, few studies have examined interactions between P. aeruginosa and commensals as well as their impact on P. aeruginosa airway infections. In the first half of this work, we studied interactions between P. aeruginosa and the oral commensal Streptococcus salivarius within a biofilm setting. We found that S. salivarius biofilm formation is promoted by the non-mucoid …

T-Bet Regulates The Maintenance And Asc Differentiation Potential Of The Lymph Node And Lung Memory B Cell Compartments, Christopher A. Risley

All ETDs from UAB

Although human memory B cells (Bmem), including extrafollicular DN2 cells and CD27+ effector Bmem (eBmem), express T-bet, its role in Bmem biology is not understood. We characterized transcriptionally distinct clusters of mature, somatically mutated nucleoprotein (NP)-specific Bmem in LNs of influenza-infected mice. None of the Bmem expressed plasma cell (PC) lineage commitment factors, but one cluster was significantly enriched for Tbx21+ cells that exhibited a molecular signature similar to the previously described human T-bet+ eBmem. Metabolic reprogramming, protein synthesis and the mTOR-dependent unfolded protein response gene networks were all upregulated in Tbx21+ NP+ mouse Bmem. Using constitutive and inducible models …

The output angle for each VHOE is +45° within the medium and the coupler operational wavelength is 633nm. Holographic recording in Bayfol HX 200 photopolymer at 532nm is used to …

Spherical Modes Driven Directional Modulation With A Compact Mimo Antenna, Abel Zamdemala, Nicola Marchetti, Max Ammann, Adam Narbudowicz

Articles

In this letter, a compact beamsteering MIMO antenna is proposed for Directional Modulation (DM) applications. A generalization of the beamsteering principle is presented and by exploiting the antenna’s unidirectional beamsteering capability within the entire azimuth plane, the system realizes secure steerable transmissions in the direction of the legitimate receiver, with a low Bit Error Rate (BER) of 10^(-5), while a high error rate of 10^(-1) is seen outside the desired regions. Numerical and experimental verifications are carried out to validate the proposed concept and comparisons with circular arrays are conducted, revealing that the system achieves comparable performance but with up …

Speculations On Force And Form: Resisting The Neurotypical In The Neoliberal University, Helen Bowstead

School of Law, Humanities and Social Sciences Theses

Can reframing a thesis in terms of what it can do rather than what it is generate a joyful-artful engagement with the PhD process and engender a more response-able relationship with the world? In this tentative exemplification of the speculative potential of force and form, the very act of writing emerges as a powerful antidote to constraints of the neoliberal university. Exploring writing as immanent doing, Erin Manning’s philosophical projects of research-creation, artfulness and thought in motion find expression through the ordinary, the everyday and the mundane. By refusing to engage in the dis-abling constraints prescribed by institutional expectations of …
