Limitations Of Beam-Control Compensation, Matthew Kalensky, Darren Getts, Matthias T. Banet, Derek J. Burrell, Milo W. Hyde, Mark F. Spencer

Faculty Publications

In this paper, we use wave-optics simulations to explore the limitations of beam-control compensation. We evaluate performance in terms of the normalized power in a diffraction-limited bucket for the cases of no beam-control compensation, perfect phase compensation, and perfect full-field compensation. From these results, we are able to arrive at the following conclusions: (1) without any form of beam-control compensation, performance begins to degrade when D/r₀ > 1; (2) with perfect phase compensation, performance begins to degrade when D/r₀ > 1 and (λ/r₀)/θ₀ > 1; and (3) with perfect full-field compensation, performance begins to degrade when D/r_{0 …}

Soc-Based Control System Performance Analysis For Trapped-Ion Quantum Computing, Tiamike Dudley

Electrical and Computer Engineering ETDs

Scatter-gather dynamic-memory-access (SG-DMA) is utilized in applications that require high bandwidth and low latency data transfers between memory and peripherals, where data blocks, described using buffer descriptors (BDs), are distributed throughout the memory system. The data transfer organization and requirements of a Trapped-Ion Quantum Computer (TIQC) possess characteristics similar to those targeted by SG-DMA. In particular, the ion qubits in a TIQC are manipulated by applying control sequences consisting primarily of modulated laser pulses. These optical pulses are defined by parameters that are (re)configured by the electrical control system. Variations in the operating environment and equipment make it necessary to …

Nonequilibrium Plasma Synthesis And Processing Of Iii-Nitride Materials, Dillon Patrick Moher

McKelvey School of Engineering Graduate Student Theses & Dissertations

Nitrogen is abundant on Earth as its diatomic form, and human activity has generated a significant demand for nitrogen-containing compounds. However, its triple bond energy of 941 kJ/mol makes it a poor reactive species in the ground state. Nitrogen-containing nonequilibrium plasmas are made up of background gas, electrons, ions, and a multitude of excited states of nitrogen or even atomic nitrogen. Many of these species have rather high reactivity. As such, the plasma medium is of great potential for driving chemical reactions that involve nitrogen as a reactant, i.e., nitrogen fixation into compounds like ammonia, high-energy-density polynitrogen compounds, and metal-nitride …

Adoption of diverse weed management practices is viewed as essential for slowing the spread of herbicide-resistant (HR) weeds. Yet, adoption of diverse tactics has remained low, while there has been explosive growth of resistant weeds. This study analyzes U.S.-farm-level data to identify factors affecting adoption of diverse weed management practices. This study uses directed acyclic graphs (DAGs) to consider how practice adoption is influenced by different causal pathways between farmer and farm characteristics and farmer awareness of and concern over HR weeds. This study then uses multiple regression analysis to estimate the direct and indirect pathways that influence practice adoption. …

Conglomeration, Digital Disruption, And Covid-19: Upheaval-Driven Changes To The Roles Of U.S. Local Television News Directors, Suzanne Lysak, Keren Henderson

Film and Media Arts Faculty Articles and Research

This mixed methods study analyzes how broadcast news directors renegotiate their roles under organizational and cultural times of change. Even before COVID-19, local television news directors, one of the two predominant groups of journalism managers in the United States, were experiencing shifts in roles related to their growing work responsibilities. These changes were the result of long-term workplace upheavals including conglomeration and digital disruption. When the COVID-19 pandemic hit, news directors found themselves managing through this additional, short-term upheaval. The authors of this study sought to discover how industry upheavals impact broadcast newsroom management roles.

Prior Probability Biases Perceptual Choices By Modulating The Accumulation Rate, Rather Than The Baseline, Of Decision Evidence, Jessica A. Diaz, M. Andrea Pisauro, Ioannis Delis, Marios G. Philiastides

School of Psychology

The prior probability of an upcoming stimulus has been shown to influence the formation of perceptual decisions. Computationally, these effects have typically been attributed to changes in the starting point (i.e., baseline) of evidence accumulation in sequential sampling models. More recently, it has also been proposed that prior probability might additionally lead to changes in the rate of evidence accumulation. Here, we introduce a neurally-informed behavioural modelling approach to understand whether prior probability influences the starting point, the rate of evidence accumulation or both. To this end, we employ a well-established visual object categorisation task for which two neural components …

Structural Stability Comparisons Between Natural And Engineered Group Ii Chaperonins: Are Crenarchaeal “Heat Shock” Proteins Also “Ph Shock” Resistant?, Mercede Furr, Shadi A.

Stacy, Yeasin Ahmed, Mahmoud Moradi, Thallapuranam Krishnaswamy Suresh Kumar, Ruben Michael Ceballos

Archaeal group II chaperonins, also known as heat shock proteins (HSPs), are abundantly expressed in Sulfolobales. HSPα and HSPβ gene expression is upregulated during thermal shock. HSPs form large 18-mer complexes that assist in folding nascent proteins and protecting resident proteins during thermal stress. Engineered HSPs have been designed for industrial applications. Since temperature flux in the geothermal habitats of Sulfolobales impacts intracellular temperature, it follows that HSPs have developed thermotolerance. However, despite the low pH (i.e., pH < 4) typical for these habitats, intracellular pH in Sulfolobales is maintained at ~6.5. Therefore, it is not presumed that HSPs have evolved acid-tolerance. To test tolerance to low pH, HSPs were studied at various pH and temperature values. Both circular dichroism and intrinsic fluorescence indicate that HSPα and HSPβ retain structural integrity at neutral pH over a wide range of temperatures. Structural integrity is compromised for all HSPs at ultra-low pH (e.g., pH 2). Secondary structures in HSPs are resilient under mildly acidic conditions (pH 4) but Anilino naphthalene 8-sulfonate binding shows shifts in tertiary structure at lower pH. Trypsin digestion shows that the HSPβ-coh backbone is the most flexible and HSPβ is the most resilient. Overall, results suggest that HSPα and HSPβ exhibit greater thermostability than HSPβ-coh and that there are limits to HSP acid-tolerance. Molecular dynamics (MD) simulations complement the wet lab data. Specifically, MD suggests that the HSPβ secondary structure is the most stable. Also, despite similarities in pH- and temperature-dependent behavior, there are clear differences in how each HSP subtype is perturbed.

Redirect-And-Sync For Distributed Stateful Network Applications, Na

Defensive Publications Series

Cloud-based networking uses various stateful networking functions. There is currently no mechanism to synchronize the states of the functions across different binaries. As a result, the functions cannot be used on stateless devices that provide higher throughput or scalability. This disclosure describes techniques to synchronize states in distributed networking systems. The network function state is defined and maintained in a distributed manner and is sharded in units of flows. A shard is assigned an owner, which handles the flows in the shard. State synchronization is achieved by having the shard owner write actions for flows it owns, and by having …

Projections And Perceptions-Editorial Comment: A Perspective On Military Geography, Eugene J. Palka

The Geographical Bulletin

During times of conflict military geography invariably surfaces as an important problem-solving subfield of geography. Since September 11, 2001, dozens of geographers employed by the Department of Defense have focused their attention on Central Asia in general and on Afghanistan in particular. Academic geographers have also been beckoned by the government, military, and media to apply their particular systematic or regional expertise to America's recent challenge. One cannot dispute the wartime relevance of the subfield, yet since the fall of the Berlin Wall, applications during peacetime and military operations other than war (MOOTW) have become more apparent (Palka and Galgano, …

Measuring Integrated Accessibility For Sustainable Mobility: A Fuzzy Set Approach Case Study, Behnam Tahmasbi, Poria Hajian, Farzaneh Tahmasbi, Qian He

School of Earth & Environment Departmental Research

Sustainable transportation is vital to climate justice and social equity. Despite the efforts to achieve sustainability, there is still a lack of adequate measurement that integrates land use and transportation systems, which can be barriers to planning implementation. With methodological improvements in fuzzy theory application, this study develops an integrated index to measure the sustainability of multimodal accessibility. We do so by defining a fuzziness degree based on the different trip purposes and modes of transportation with a case study in Isfahan, Iran. Sustainable accessibility indicators were developed for walking, biking, and public transportation to represent the performance of each …

Powerful Women—A Man-Made Fear: Unmasking The Vilification Of Women In Literature Through The Lens Of Jean Grey, Maximillan Wilson

Master of Liberal Studies Projects

Comic books in their current form have been a staple of American pop culture for nearly a century. The combination of art and narrative provides a unique storytelling medium that has evolved with each new batch of artists and authors over the decades. The imagination's impossible and fantastical qualities are actualized in ways that non-visual literature cannot compete with, reaching audiences of all ages and reading comprehension. However, like with all fiction, the influence of reality cannot be denied. Despite the colorful costumes and progressive storylines, comic book stories suffer from a long-standing misogynistic motive that has long plagued literature. …
