Roles for ubiquitin and dimensional dependence in protein regulation

ubiquitin

description: Ubiquitin is a small protein which interacts with other proteins as a post-translational modification and as a binding partner for proteins which contain a ubiquitin binding domain (UBD). Proteins modified with ubiquitin are often targeted for degradation. Ubiquitin regulates both soluble and membrane-bound proteins in cells of nearly all tissues. Here we use mathematical models to study three distinct regulatory systems involving ubiquitin: regulation of the yeast uracil transporter, Fur4, protein sorting mediated by the endosomal sorting complexes required for transport (ESCRTs), and regulation of Rad18 in the DNA damage tolerance pathway. Using a differential equation model of Fur4 regulation, we demonstrate that deubiquitination and retention are essential roles of the Rsp5/Ubp2 complex localized to the endosome. We also predict a nearly constant pool of endosomal Fur4 independent of extracellular conditions. ESCRTs are responsible for sorting ubiquitinated proteins (cargo) on the endosomal membrane prior to formation of intralumenal vesicles. However, the mechanisms of sorting remain unclear. Motivated by recent experimental data, we present a cellular automata model of ESCRT sorting which demonstrates that a flexible network of ESCRTs and cargoes is sufficient for high efficiency sorting under specified rules. ESCRT-cargo networks exist on membranes while all ESCRT binding studies consider ESCRT interactions in solution. We present novel results on the dimensional dependence of dissociation constants for general protein-protein interactions using stochastic methods. We present a conversion for transforming three-dimensional dissociation constants to two-dimensional dissociation constants and demonstrate that ESCRT-cargo interactions are more stable on membranes than in solution. Using our computed two-dimensional reaction rates, we present an ODE model for the evolution of the size of ESCRT-cargo networks. Our results suggest that ESCRT-mediated sorting can be achieved on the order of seconds. Lastly, we examine ubiquitin-dependent regulation of Rad18 in the DNA damage tolerance pathway, a system of strictly soluble proteins which does not rely on ubiquitin-dependent degradation. Results of ODE models suggest that the dissociation constants for Rad18 binding events must be measured in order to better understand the mechanisms behind damage-specific responses.
Invariance principles in functional time series analysis with applications

description: This dissertation aims to develop the theory and applications of functional time series analysis. Functional data analysis came into prominence in the 1990s when more sophisticated data collection and storage systems became prevalent, and many of the early developments focused on simple random samples of curves. However, a common source of functional data is when long, continuous records are broken into segments of smaller curves. An example of this is geologic and economic data that are presented as hourly or daily curves. In these instances, successive curves may exhibit dependencies which invalidate statistical procedures that assume a simple random sample. The theory of functional time series analysis has grown tremendously in the last decade to provide methodology for such data, and researchers have focused primarily on adapting methods available in finite dimensional time series analysis to the function space setting. As a first problem, we consider an invariance principle for the partial sum process of stationary random functions. This theory is then applied to the problems of testing for stationarity of a functional time series and the one-way functional analysis of variance problem under dependence.

description: Parameters of the mathematical model describing many practical dynamical systems are prone to vary due to aging or renewal, wear and tear, as well as changes in environmental or service conditions. These variabilities will adversely affect the accuracy of state estimation. In this paper, we introduce SSUE: Simultaneous State and Uncertainty Estimation for quantifying parameter uncertainty while simultaneously estimating the internal state of a system. Our approach involves the development of a Bayesian framework that recursively updates the posterior joint density of the unknown state vector and parameter uncertainty. To execute the framework for practical implementation, we develop a computational algorithm based on maximum a posteriori estimation and the numerical Newton's method. Observability analysis is conducted for linear systems, and its relation with the consistency of the estimation of the uncertainty's location is unveiled. Additional simulation results are provided to demonstrate the effectiveness of the proposed SSUE approach.

description: Lithium is generally considered to be a simple metal, given its simple electronic structure with one valence electron.  It is considered to follow a nearly free electron model and have a nearly spherical Fermi surface.  However, away from ambient conditions, the behavior of lithium become much less simple.  Under high pressures, lithium undergoes a series of symmetry-breaking phase transitions, even a metal to insulator transition; at low temperatures, lithium also undergoes a temperature-driven martensitic transformation.  In this work, these deviations from simple models in lithium are investigated, both at ambient pressure and under high pressures, from the relative high temperature phenomenon of melting to low temperature measurements of superconductivity.

description: Super-resolution light microscopy overcomes the physical barriers due to light diffraction, allowing for the observation of otherwise indistinguishable subcellular entities. However, the specific acquisition conditions required by state-of-the-art super-resolution methods to achieve adequate spatio-temporal resolution are often very challenging. Exploiting molecules fluctuations allows good spatio-temporal resolution live-cell imaging by means of common microscopes and conventional fluorescent dyes. In this work, we present the method COL0RME for COvariance-based $\ell_0$ super-Resolution Microscopy with intensity Estimation. It codifies the assumption of sparse distribution of the fluorescent molecules as well as the temporal and spatial independence between emitters via a non-convex optimization problem formulated in the covariance domain. In order to deal with real data, the proposed approach also estimates background and noise statistics. It also includes a final estimation step where intensity information is retrieved, which is valuable for biological interpretation and future applications to super-resolution imaging.

description: This dissertation examines the effects of race, neighborhood poverty, and racial segregation on homelessness and housing instability in the U.S.  African Americans are disproportionately represented in the American homeless population, yet little research has explored this racial inequality. This study contributes to the literature by examining Black-White disparities for multiple measures of housing instability, including homelessness, and the individual pathways underlying these differences. In addition, community-level segregation and poverty have helped to explain racial disparities in other outcomes for health and wellbeing. I also examine the effects of community-level segregation and poverty on housing instability and homelessness in general and on racial disparities in particular. Using data from the Fragile Families and Child Wellbeing (FFCW) longitudinal survey, I find that Black mothers have higher odds of experiencing homelessness and doubling-up with others for financial reasons, but no such differences were found for odds of eviction or frequent moves. Additionally, neighborhood poverty and segregation are significant for some measures of housing instability over and above individual socioeconomic characteristics. For homelessness specifically, due to the difficulty obtaining sufficient and quality data, I use two datasets to explore race and place effects for this outcome. Using administrative data from the U.S. Department of Housing and Urban Development, I find that racial segregation contributes to the disproportionate number of Black persons in the homeless population. Finally, using a restricted sample from the FFCW survey to mirror program targeting, I find that risk factors differ for Black and White mothers for homelessness.

description: We consider a compact perturbation $H_0 = S + K_0^* K_0$ of a self-adjoint operator $S$ with an eigenvalue $λ^\circ$ below its essential spectrum and the corresponding eigenfunction $f$. The perturbation is assumed to be "along" the eigenfunction $f$, namely $K_0f=0$. The eigenvalue $λ^\circ$ belongs to the spectra of both $H_0$ and $S$. Let $S$ have $σ$ more eigenvalues below $λ^\circ$ than $H_0$; $σ$ is known as the spectral shift at $λ^\circ$. We now allow the perturbation to vary in a suitable operator space and study the continuation of the eigenvalue $λ^\circ$ in the spectrum of $H(K)=S + K^* K$. We show that the eigenvalue as a function of $K$ has a critical point at $K=K_0$ and the Morse index of this critical point is the spectral shift $σ$. A version of this theorem also holds for some non-positive perturbations.

description: Representations in the form of concept maps have been shown to be a benefit to leaners. However, previous research examined the influence of these representations in learning in well-structured environments. Additionally, previous research suggests that increasing the activity of students in learning environments has also been shown to yield gains in learning, called the generation effect. The current study extends the literature by examining the influence generative activities and concept map representations have on an ill-structured reasoning process, namely thinking like a lawyer. Pre- and posttests targeting factual knowledge, recall, and transfer were used to assess learning, while verbal protocols were implemented to examine learning processes used by participants. Results were mixed. Representation and activity had no effect on factual knowledge, recall, and near transfer measures. Verbal protocol results showed that students who studied with the concept map representation condition produced a higher proportion of deep utterances during problem solving when using static representations compared to those that generated their representation. The opposite was true for students in the text list condition. Those who generated their text list representation during study produced a higher proportion of deep utterances in problem solving when compared to those who studied with a static list. Thus, a careful consideration of topical materials and learning environments is necessary to determine whether or not concept maps and generation effects will encourage deeper comprehension in learners.

description: We propose a continuous neural network architecture, termed Explainable Tensorized Neural Ordinary Differential Equations (ETN-ODE), for multi-step time series prediction at arbitrary time points. Unlike the existing approaches, which mainly handle univariate time series for multi-step prediction or multivariate time series for single-step prediction, ETN-ODE could model multivariate time series for arbitrary-step prediction. In addition, it enjoys a tandem attention, w.r.t. temporal attention and variable attention, being able to provide explainable insights into the data. Specifically, ETN-ODE combines an explainable Tensorized Gated Recurrent Unit (Tensorized GRU or TGRU) with Ordinary Differential Equations (ODE). The derivative of the latent states is parameterized with a neural network. This continuous-time ODE network enables a multi-step prediction at arbitrary time points. We quantitatively and qualitatively demonstrate the effectiveness and the interpretability of ETN-ODE on five different multi-step prediction tasks and one arbitrary-step prediction task. Extensive experiments show that ETN-ODE can lead to accurate predictions at arbitrary time points while attaining best performance against the baseline methods in standard multi-step time series prediction.

description: This study investigates the effectiveness of search engine marketing (SEM) on consumer behaviour, focusing on purchase decisions and brand awareness. A descriptive research design was employed, involving a survey of 100 participants. The findings reveal that SEM can be an effective tool for reaching and influencing consumers, particularly younger demographics. However, the effectiveness of SEM depends on factors such as ad relevance, targeting, and optimization. The study recommends that businesses focus on creating relevant and personalized ad content, optimizing campaigns for mobile devices, leveraging local SEO, and continuously tracking and analysing campaign performance to maximize the effectiveness of SEM
A constructive theory of the numerically accessible many-body localized to thermal crossover

description: The many-body localised (MBL) to thermal crossover observed in exact diagonalisation studies remains poorly understood as the accessible system sizes are too small to be in an asymptotic scaling regime. We develop a model of the crossover in short 1D chains in which the MBL phase is destabilised by the formation of many-body resonances. The model reproduces several properties of the numerically observed crossover, including an apparent correlation length exponent $ν=1$, exponential growth of the Thouless time with disorder strength, linear drift of the critical disorder strength with system size, scale-free resonances, apparent $1/ω$ dependence of disorder-averaged spectral functions, and sub-thermal entanglement entropy of small subsystems. In the crossover, resonances induced by a local perturbation are rare at numerically accessible system sizes $L$ which are smaller than a \emph{resonance length} $λ$. For $L \gg \sqrtλ$, resonances typically overlap, and this model does not describe the asymptotic transition. The model further reproduces controversial numerical observations which Refs. [Šuntajs et al, 2019] and [Sels & Polkovnikov, 2020] claimed to be inconsistent with MBL. We thus argue that the numerics to date is consistent with a MBL phase in the thermodynamic limit.

description: Facies and stratigraphic analysis of the John Henry Member of the Upper Cretaceous Straight Cliffs Formation, exposed in the northern Kaiparowits Plateau of southern Utah, reveals deposition of four regressive-transgressive (R-T) cycles. Each of the four R-T cycles is discussed in detail, with emphasis on the transgressive phases of deposition. Fifteen lithofacies (LF) are grouped into four facies associations (FAs): FA-1: wave-dominated shorefaces; FA-2: coastal plain; FA-3: tide-influenced coastal margin; FA-4: low-energy bay/lagoon. Regressive deposits preserve FA-1 and FA-2, whereas FA-3 and FA-4 comprise transgressive intervals. Seven bounding surfaces and elements define the regressive-transgressive architecture: 1) maximum regressive surface (mRs); 2) process change from wave- to tide-dominated processes (pCt); 3) tidal ravinement surface (tRs); 4) wave ravinement surface (wRs); 5) flooding surface (FS); 6) tide- to fluvial-dominated process change (pCf); and 7) the subaerial unconformity (SU).  At Main Canyon, a stepped, forced regression is associated with the development of shore oblique incised valleys. A composite stratigraphic surface (SU/mRs/tRs), referred to here as the ""lower John Henry Member sequence boundary,"" separates regressive shorefaces from overlying high-energy, transgressive estuarine and backbarrier deposits. Basinward, the correlative conformity is preserved as sharp-based wavedominated, river-influenced shorefaces. Overlying R-T cycles are not associated with valley incision, but instead preserve sand-rich back-barrier and tidal channel deposits which are overlain distributary mouth bars, fluvial channels and coastal plain fines, which record infilling of the back-barrier. The preservation of >30 m thick accumulations of back-barrier deposits indicate an accretionary shoreline trajectory with balanced rates of high sediment supply and accommodation. Regional correlation across the northern Kaiparowits Plateau indicate 47% expansion of the John Henry Member occurring over ~14 km from southwest to northeast, with a steep topographic gradient of 0.011. These results suggest structural deformation of the foredeep was occurring from Coniacian to Campanian time, controlling sediment transport, and depositional patterns across the Kaiparowits subbasin. Allogenic and autogenic processes are considered as controls on the stratigraphic architecture for successive regressive-transgressive cycles. This study adds to the growing body of literature documenting the complex nature of transgressive deposits, which will aid in the prediction and management of analogues subsurface reservoirs.
Influence of hospital bed height on kinematic parameters associated with patient falls during egress

description: Understanding the quantitative aspects of kinematic and temporal parameters in fall-prone populations in natural environments is important, particularly in settings replicating hospital environments where patients are often impaired and less familiarized with the layout. Studies indicate fall rates are much higher in these settings than in comparable community settings. The aim of this study was to determine how bed height and side rail presence/type influence fall risk when patients get out of bed unassisted. Seventy-nine older adults with mobility impairments performed an unconstrained sit-to-walk movement at three randomized bed heights representing low, medium, and high bed conditions. Three side rail conditions were also studied. Temporal and kinematic parameters were obtained from key sit-to-walk movement events using 3D motion capture and ground reaction forces. There was no evidence that the presence of side rails influenced kinematics. Temporal parameters proved to be most affected by bed heights, particularly in the low bed condition. Velocity and momentum parameters were less significantly affected between conditions. Participants appeared to use similar momentum strategies to rise and initiate gait but altered their timing in order to accommodate their balance deficits. This study supports the model that suggests increased impairment leads to slower movement event timing during sit-to-walk transition. This study did not support other findings that mediolateral kinematics were higher in those with greater impairments, nor did bed height alter any of these kinematics at any event. Participants had statistically significant higher forward velocities when initiating gait from the medium bed condition, and they had statistically significant lower posterior momenta when exiting the high bed condition. These could be indications of increased mobility and improved use of generated kinetic energy. These represent potentially favorable results in light of reducing fall risk. Medium bed height appeared to produce the least significant differences in parameters when compared to the two other bed heights. This implies the most flexibility to prioritize postural stability or postural mobility. Low bed heights generated particular problems by reducing fluid motion and creating more impediments to postural stability. This suggests that low bed heights may not reduce fall rates during bed exit.

description: Trichotillomania is an understudied chronic condition with unknown etiology and epidemiology that affects a significant number of girls and women. This study addressed the overarching question, What are the experiences and perceptions of women who engage in hair pulling? "Trichotillomania: A Journey of Personal Empowerment" was a qualitative study of 22 women that addressed their lived experience of hair pulling and their assigned meaning of their hair pulling. Data were collected through in-depth interviews with each participant. A grounded theory approach to analysis was applied to the data. The narratives of the participants yielded an understanding of when and why hair pulling took hold, how others' conceptualizations of trichotillomania created barriers to accountability and acceptance, and how women empowered themselves to conceptualize their hair pulling and to determine the role that hair pulling plays in their lives. The women's conceptualizations of trichotillomania, based on their experiences and perceptions of their hair pulling, provided clear evidence for why it is so important to include hair pullers in the global conversation on trichotillomania.

description: Over the past three decades adolescents have increasingly become involved in athletics. Previous research assessed the level of sport nutrition knowledge among these youth. However, most of the tools that were used did not undergo rigorous analysis to ensure valid and reliable assessment of these young athletes' knowledge. The purpose of this study was to develop the Adolescent Sport Nutrition Knowledge Questionnaire and establish validity and reliability. The instrument consists of three sections: 1 ) demographics and history of sport participation; 2 ) questions related to nutrition attitudes and behaviors; 3) a 63-item true/false/unknown test of sport nutrition knowledge for seven varying subscales. A panel of ten experts evaluated the developed questionnaire and established construct validity. A group of 42 university students established predictive validity between the two groups with distinct knowledge differences (r2=0.05; p=0.1S). In this study, 138 adolescent male and female participants (mean age: 15.6 ± 1.16 years old) completed the questionnaire once, and 42 of these individuals completed it a second time to establish the tools reliability. The average sport nutrition knowledge score was 41.72 ± 7.81; n=134. Internal consistency of the tool was 0.86 with a narrow 95% confidence interval of 0.74-0.92 displaying a ‘good' level of reliability; however, the individual subscales were not independently reliable. Analysis of the individual questions provides evidence that there is a low level of understanding of nutritional recommendations for athletes. Stepwise multiple regression revealed age (/?=0.004) and ‘parents as the primary source of nutrition information' (p=0.002) as predictors of sport nutrition knowledge (/= 0.16; explaining 16% of the variance). This study suggests that the Sport Nutrition Knowledge Questionnaire is a valid and reliable tool to assess overall sport nutrition knowledge in adolescent athletes. However, further development of the subscales would need to be conducted to assess knowledge within these individual constructs. Sports dietitians, coaches and athletic trainers can utilize this tool to assess knowledge in adolescent athletes and to test the efficacy of sport nutrition interventions among athletes and teams.

description: The claim has been made that the nineteenth century's interest in libertine fiction is merely ""archival."" This dissertation seeks to contest that claim by examining the reuse of certain well-known, if not notorious, characters from European seduction narratives of the fifteenth, seventeenth, and eighteenth centuries--Valmont, Don Juan, and Tannhuser--in the work of George Gordon, Lord Byron, Charles Baudelaire, Algernon Swinburne, and Aubrey Beardsley. It finds that these seducers are not static characters deployed for the purpose of allusion or critique, but heroes, reworked and rehabilitated as the central figures of literary seductions intended to entice and control the reader and address the perceived inequities of nineteenth-century morality or politics. By applying a four-phase framework for seduction derived from canonical seduction narratives, the argument demonstrates how the reinvented seducers have been stripped down, personalized, redressed, and recontextualized in narratives that seek to compel through seduction and educate through experience.
Towards a decided body and choreography

description: This thesis examines a state termed the decided body, which describes an engaging and qualitatively fluid presence in performance.  My research explored this state of presence and drew from the embodied qualities arising out of the state as source material for choreography.  Dancers were trained in passive sequencing, which is a somatic technique where a conscious body passively resists intentional movement and is instead physically moved by others. The process of passive sequencing produced a particular state of embodied conscious that allowed dancers to intuitively initiate new pathways of movement in the action of improvising. This thesis tracks the creation of two new dance works built from the process of passive sequencing to improvisation to setting choreography and then to preparing for performance.  It also provides a theoretical framework from performance studies and contemporary healing practices on how passive sequencing functions on the body-mind complex to create this state of the decided body.

description: A few potential IoT communication protocols at the application layer have been proposed, including MQTT, CoAP and REST HTTP, with the latter being the protocol of choice for software developers due to its compatibility with the existing systems. We present a theoretical model of the expected buffer size on the REST HTTP client buffer in IoT devices under lossy wireless conditions, and validate the study experimentally. The results show that increasing the buffer size in IoT devices does not always improve performance in lossy environments, hence demonstrating the importance of benchmarking the buffer size in IoT systems deploying REST HTTP.

description: A proper edge coloring of a graph is strong if it creates no bichromatic path of length three. It is well known that for a strong edge coloring of a $k$-regular graph at least $2k-1$ colors are needed. We show that a $k$-regular graph admits a strong edge coloring with $2k-1$ colors if and only if it covers the Kneser graph $K(2k-1,k-1)$. In particular, a cubic graph is strongly $5$-edge-colorable whenever it covers the Petersen graph. One of the implications of this result is that a conjecture about strong edge colorings of subcubic graphs proposed by Faudree et al. [Ars Combin. 29 B (1990), 205--211] is false.

description: Nearshore fluvial to tidal transitional depositional systems are becoming increasingly important due to the large number of global hydrocarbon reserves held in such deposits. These deposits are inherently complex due to their heterolithic nature and therefore, interpreting facies and facies relationships in seismic reflection profiles is problematic. The fluvial and tidally influenced nearshore deposits of the late Cretaceous John Henry Member (JHM) of the Straight Cliffs Formation, located in the Kaiparowits Plateau of southern Utah, offers an excellent opportunity to improve our understanding of how the fluvial to tidal  transition impacts subsurface petroleum reservoirs and their expression in seismic reflection profiles.   The focus of the first chapter is to investigate the impact of heterogeneous depositional environments and their rock properties to model amplitude versus offset (AVO) using a single core. Core EP-25 exhibits lithofacies from a progradational succession, from shoreface through tidal to fluvial. In order to model the most likely lithofacies stacking patterns present in the core, Markov Chain analysis was conducted. Benchtop measurements performed on 1 inch core plugs obtained rock properties (Vp, Vs, density, permeability, and porosity) for each lithofacies. Average rock properties for each lithofacies were used to generate synthetic seismic reflection models of the different upward fining facies associations documented directly from the core, in order to model variations in amplitude versus offset responses as a function of variable tidal influence.  The focus of the second chapter is to capture probable 3-dimensional geobody distributions with a particular focus on coal geobody distribution using previously studied cores and outcrops on the plateau. Three different seismic forward models were created ranging in complexity, using cores EP-25, EP-07, density logs, and the nearby outcrop study Left Hand Collet. The rock properties obtained from the benchtop measurements were used to populate the three models based on different depositional environments at the separate depth slices capturing multiple geomorphic rather than stratigraphic models. A seismic survey was acquired on the plateau using 80 Hz frequency; this produced a high-resolution seismic profile. Comparing the forward seismic model to the acquired seismic profile allows for a conceptual understanding between predictive models of what is expected and what is captured in seismic reflection profiles.

The role of mixed dominance in bilingual assessment

description: The Bilingual English Spanish Assessment (BESA) is a new standardized test normed on young bilingual children who speak Spanish and English. This bilingual standardized measure is unique because it considers the possibility that children might have differential semantic and grammatical abilities across their two languages. The BESA's scoring scheme accounts for mixed dominance by allowing children to demonstrate best performance. Information on how this new measure aligns with other indices of underlying language ability, such as parent questionnaires and nonword repetition (NWR) is needed. Information of this type could lead to the development of new screening procedures. Twenty-six Hispanic Spanish/English-speaking children were recruited from Salt Lake City, Utah. Parents reported on children's input/output in both languages and rated their Spanish and English abilities using the Speech Language Assessment Scale (SLAS). Participants were administered three nonword repetition tasks and the BESA. An English NWR task and a Spanish NWR task were administered to each child. The highest achieved score from the Spanish and English NWR tasks was used to allow for mixed dominance across languages (NWR-best). A recently developed framework was used to create a quasi-universal NWR task with quasineutral prosody with syllable patterns and phonemes in English and Spanish (NWR-U). Results of correlational and regression analyses indicated that performances across the NWR tasks were highly correlated with participants' performance on the BESA. The parent ratings from the SLAS were moderately correlated with performance on the BESA. A linear regression analysis including the SLAS, NWR-best, and NWR-U accounted for 82% of the variability in children's BESA scores. A second linear regression analysis including NWR-best and NWR-U indicated that on its own, NWR-U accounted for 85% of the variability in children's BESA scores. These findings suggest that NWR measures in general and the created quasiuniversal NWR measure in particular, show promise as potential screeners for young Spanish/English bilinguals. Parent questionnaires continue to be useful in collecting current information regarding bilingual children's language abilities. Using NWR-U with bilingual children might represent an appealing alternative because it can account for both languages and potentially maintain high levels of diagnostic accuracy.
