description: This paper discusses the impact of introducing a planet on an eccentric orbit into a planetesimal disk. That planet's secular perturbations cause the orbits of the planetesimals to evolve in such a way that at any one time planetesimals at the same distance from the star have common pericentres and eccentricities. This causes the surface density distribution of an extended planetesimal disk to exhibit two spirals, one exterior the other interior to the planet's orbit. These two spirals unwind in different directions and their structure is described by two parameters: the time since the planet was introduced and the planet's eccentricity. At late times the spirals become tightly wound and the offset centre of symmetry of the pericentre glow approximation is recovered. Comparison with spiral structure seen in the HD141569 disk shows that its spiral at 325 AU is similar to that caused by introducing a planet 5 Myr ago with a mass 0.2-2M_Jup orbiting at 235-250 AU with an eccentricity of 0.05-0.2; likewise a Saturn mass planet at 150 AU would cause structure like that seen at 200 AU. More definitive statements about any planets orbiting HD141569 from this model could be made once the effect of the binary companion on the disk is known, and once the disk's structure has been better characterised down to 100 AU, including the location of the star within the disk. The relatively young age of this system (~5 Myr) means that if giant planets really do exist at hundreds of AU from HD141569, this provides a unique opportunity to set constraints on the mechanism by which those planets came to be at such large distances.

description: Eosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus, characterized by penetration of eosinophils into the esophageal wall. Once thought to be a rare condition, incidents of EoE are becoming more common. As EoE has risen to prominence, significant effort has been undertaken to successfully diagnose and treat the disease. Most studies of EoE have utilized a typical approach of biological assessment. Although this approach is successful, it may neglect fundamental biophysics that impact the progression and treatment of the disease. The use of engineering methods to create a physics-based assessment of EoE defines a biophysical model to answer fundamental questions concerning EoE development, which can be used in the treatment of the disease. The methods and techniques are common in traditional engineering applications and are used to obtain insight into a physical system through mathematical application. This work examines a purported relationship between eosinophil concentration and esophageal morphology. The pathogenesis of EoE using conservation principles is performed. Finally, a model for delivery of hydrophobic drugs from polymeric micelles is presented, which vessels can be utilized for delivery of drugs into the epithelium in the esophagus.

description: The BL Lac object 3C 66A was the target of an extensive multiwavelength monitoring campaign from July 2003 through April 2004, involving observations throughout the electromagnetic spectrum. Radio, infrared, and optical observations were carried out by the WEBT-ENIGMA collaboration. At higher energies, 3C 66A was observed in X-rays (RXTE), and at very-high-energy (VHE) gamma-rays (STACEE, VERITAS). In addition, the source has been observed with the VLBA at 9 epochs throughout the period September 2003 - December 2004, including 3 epochs contemporaneous with the core campaign.The WEBT campaign revealed microvariability with flux changes of ~ 5 % on time scales as short as \~ 2 hr. The source was in a relatively bright state, with several bright flares on time scales of several days. The SED indicates a $νF_ν$ peak in the optical regime. A weak trend of optical spectral hysteresis with a trend of spectral softening throughout both the rising and decaying phases, has been found. The 3 - 10 keV X-ray flux of 3C 66A during the core campaign was historically high and its spectrum very soft, indicating that the low-frequency component of the broadband SED extends beyond ~ 10 keV. No significant X-ray flux and/or spectral variability was detected. STACEE and Whipple observations provided upper flux limits at > 150 GeV and > 390 GeV, respectively. The 22 and 43 GHz data from the 3 VLBA epochs between September 2003 and January 2004 indicate a smooth jet with only moderate internal structure. Evidence for superluminal motion (8.5 +/- 5.6 h^{-1} c) was found in only one out of 6 components. The radial radio brightness profile suggests a magnetic field decay $\propto r^{-1}$ and, thus, a predominantly perpendicular magnetic field.

description: Inspiraling and merging binary neutron stars are not only important source of gravitational waves, but also promising candidates for coincident electromagnetic counterparts. These systems are thought to be progenitors of short gamma-ray bursts (sGRBs). We have shown previously that binary neutron star mergers that undergo {\it delayed} collapse to a black hole surrounded by a {\it weighty} magnetized accretion disk can drive magnetically-powered jets. We now perform magnetohydrodynamic simulations in full general relativity of binary neutron stars mergers that undergo {\it prompt} collapse to explore the possibility of jet formation from black hole-{\it light} accretion disk remnants. We find that after $t-t_{\rm BH}\sim 26(M_{\rm NS}/1.8M_\odot)$ms [$M_{\rm NS}$ is the ADM mass] following prompt black hole formation, there is no evidence of mass outflow or magnetic field collimation. The rapid formation of the black hole following merger prevents magnetic energy from approaching force-free values above the magnetic poles, which is required for the launching of a jet by the usual Blandford--Znajek mechanism. Detection of gravitational waves in coincidence with sGRBs may provide constraints on the nuclear equation of state (EOS): the fate of an NSNS merger--delayed or prompt collapse, and hence the appearance or nonappearance of an sGRB--depends on a critical value of the total mass of the binary, and this value is sensitive to the EOS.

description: Out of the three major constituents of cognitive load theory, intrinsic is the most crucial as it relates to difficulty of learning material. Difficulty of learning material is determined by two factors: the learner's prior knowledge and interacting elements present in the task. The proposed study investigated the role of two formats of worked examples (full and worked) in mathematical problem solving taking into account the learner's prior knowledge and difficulty of the presented material. One hundred and sixty participants were recruited for the study. The participants solved algebraic systems of equations by either using full or completion worked examples approach. Participants were identified as low-prior-knowledge learners or high-prior-knowledge learners based on their performance on the prior knowledge test, using a median split method in which the top one-third and lower one-third participants were retained, with the middle one-third excluded from final analyses. Results indicated that both low- and high-prior-knowledge learners found completion worked examples to be beneficial in solving easy problems and full worked examples in solving difficult problems. This finding is contradictory to the expertise reversal effect. Significant positive correlation was found between intrinsic and germane cognitive load while a significant negative correlation was found between extraneous and germane cognitive load. Both of these significant correlations are aligned with proposals from previous research. Results of the motivation questionnaire indicated that interest was significantly positively correlated with germane load implying that interest in the instructional domain is an important determinant in effecting germane load.

Matrix Metalloproteinase Responsive Silk-Elastinlike Protein Polymers for Cancer Gene Therapy
Creators: name: Price, Robert Andrew
Publisher: name: University of Utah
Year: 2019

description: Treatment methodologies employed in the management of head and neck cancer must be carefully chosen and matched to each patient. Currently, surgical resection with adjuvant chemotherapy and radiation are the standard of care; however, these often cause disfigurement and scarring in addition to the toxic effects of chemotherapeutics. There are benefits to a locally applied controlled release matrix that is capable of completely resorbing into the body, and responding to the invasiveness of each case by increasing delivery rate as a function of microenvironment. Matrix metalloproteinase (MMP) responsive silk-elastinlike protein polymers (SELPs) show potential for development of such matrices. MMPs, a class of enzymes overexpressed in a variety of tumors including head and neck cancer, are an ideal target for the design of a tumor responsive controlled release depot. SELPs as a class of polymers have shown benefit in matrix mediated viral gene delivery to solid tumors; however, in this dissertation it is shown that despite superior safety, tumor size suppression, and survival prolongation in a murine cancer model do not readily resorb. Through recombinant DNA technology new SELP analogues based on SELP815K were designed and synthesized. MMP-responsive SELPs with insertion sites in the three structurally distinct regions termed SELP815K-RS1, SELP815K-RS2, and SELP815K-RS5 were tested for physiochemical similarity to their parent structure, SELP815K. Structural disruption was observed as evidenced by an increase in minimum gel forming concentration, soluble fraction, and swelling ratio as a function of proximity to the main structural unit, the silk blocks. High shear force was used to condition the matrices and normalized properties more closely to SELP815K. The resultant materials were assayed for degradation in the presence of MMP-2, as well as in a murine model of head and neck cancer. All MMP-responsive polymers showed increased degradation with SELP815K-RS1 and SELP815K-RS2 degrading most effectively as evidenced by soluble fraction released from hydrogels. Similarly, upon in vivo application these two polymers exhibited the most favorable properties including increased degradation, tumor suppression, and survival elongation. These results lead the way to prospective application of this technology in the human disease condition.

description: We summarize a selection process to identify red giants in the direction of the southern warp of the Galactic disk, employing VI_C photometry and multi-object spectroscopy. We also present results from follow-up high-resolution, high-S/N echelle spectroscopy of three field red giants, finding [Fe/H] values of about -0.5. The field stars, with Galactocentric distances estimated at 10 to 15 kpc, support the conclusion of Yong, Carney, & de Almeida (2005) that the Galactic metallicity gradient disappears beyond R_GC values of 10 to 12 kpc for the older stars and clusters of the outer disk. The field and cluster stars at such large distances show very similar abundance patterns, and, in particular, all show enhancements of the "alpha" elements O, Mg, Si, Ca, and Ti and the r-process element Eu. These results suggest that Type II supernovae have been significant contributors to star formation in the outer disk relative to Type Ia supernovae within the past few Gyrs. We also compare our results with those available for much younger objects. The limited results for the H II regions and B stars in the outer disk also suggest that the radial metallicity gradient in the outer disk is shallow or absent. The much more extensive results for Cepheids confirm these trends, and that the change in slope of the metallicity gradient may occur at a larger Galactocentric distance than for the older stars and clusters. However, the younger stars also show rising alpha element enhancements with increasing R_GC, at least beyond 12 kpc. These trends are consistent with the idea of a progressive growth in the size of the Galactic disk with time, and episodic enrichment by Type II supernovae as part of the disk's growth. [Abridged]

description: We have investigated the superconducting ground state of the newly discovered superconductor ThFeAsN with a tetragonal layered crystal structure using resistivity, magnetization, heat capacity and transverse-field (TF) muon-spin rotation ($μ$SR) measurements. Our resistivity and magnetization measurements reveal an onset of bulk superconductivity with $T_{\bf c}\sim$ 30 K. The heat capacity results show a very small anomaly, $Δ$C$_{ele}$$\sim$0.214 (J/mol-K) at $T_{\bf c}\sim$ 30 K and exhibits exponential behavior below $T_{\bf c}$, which fits better to two superconducting gaps rather than a single gap. Further a nonlinear magnetic field dependence of the electronic specific heat coefficient $γ$(H) has been found in the low temperature limit, which indicates that the smaller energy gap is nodal. Our analysis of the TF-$μ$SR results shows that the temperature dependence of the superfluid density is better described by a two-gap model either isotropic $s$+$s$-wave or $s$+$d$-wave than a single gap isotropic $s$-wave model for the superconducting gap, consistent with other Fe-based superconductors. The combine $γ$(H) and TF-$μ$SR results confirm $s$+$d$-wave model for the gap structure of ThFeAsN. The observation of two gaps in ThFeAsN suggests multiband nature of the superconductivity possibly arising from the d-bands of Fe ions. Furthermore, from our TF-$μ$SR study we have estimated the magnetic penetration depth, in the polycrystalline sample, of $λ_{\mathrm{L}}$$(0)$ = 375 nm, superconducting carrier density $n_s = 4.6 \times 10^{27}~ $m$^{-3}$, and carrier's effective-mass $m^*$ = 2.205\textit{m}$_{e}$. We will compare the results of our present study with those reported for the Fe-pnictide family of superconductors.

description: The thermodynamic and electrochemical properties of rare earth chlorides in molten salt solutions are of interest from the standpoint of both pyrochemical processing of spent nuclear fuel and for the development of Generation IV nuclear reactors. Knowledge of key properties like activity coefficients, phase diagrams and reliable waste disposal methods will accelerate the development of safe reliable carbon free energy. In this work, three conduits of research have been pursued and reported within the larger theme of minimization of waste in spent fuel reprocessing and associated technology development. First a novel process for the disposal of chloride salts using H-Y zeolite has been studied. In this process, a protonated Y zeolite is used to occlude the LiCl-KCl eutectic salt. In the process, the proton and the chloride ions react to evolve HCl gas that can be easily captured and neutralized. Hence the final waste form will be lighter compared to the baseline process. Results indicate that the proton and chloride react to form HCl gas which was captured and neutralized. Up to 50% of theoretical ion exchange was achieved based on the total HCl evolution. The activity of four rare earth chlorides was determined electrochemically in LiCl-KCl eutectic salt. These rare earth chlorides are: LaCl3, NdCl3, GdCl3, and CeCl3. The activity was determined using two distinct experimental set-ups: using a Ag/AgCl reference electrode and an analyte reference electrode. Broadly it is noted that the activity coefficient of the rare earth chlorides changes with concentration of the analyte in solution. From the data of all of the four rare earth chlorides it was concluded that as the ionic size of the rare earth reduces, the species shows a larger negative deviation from ideal solution behavior. The presence of large concentrations of CsCl seems to influence the activity of some of the rare earths. The solidus and liquidus temperatures for quaternary LiCl-KCl-CsCl-RECl 3 systems were determined using a differential scanning calorimetry. It is observed that the presence of CsCl depresses the melting temperature for all of the rare earth chlorides tested. The LiCl-KCl-CsCl-LaCl3 system departs from eutectic behavior and manifests peritectic behavior. The LiCl-KCl-CsCl-GdCl3 system shows peritectic behavior at only low GdCl 3 and high CsCl concentrations. The LiCl-KCl-CsCl-NdCl3 system continues to exhibit purely eutectic behavior for all of the concentration windows tested for this work.

description: We present the results from the dynamical analysis of the cluster of galaxies RX J0152-1357, which shows a complex structure in its X-ray emission, with two major clumps in the central region, and a third clump in the Eastern region. Our analysis is based on redshift data for 187 galaxies. We compute the line-of-sight velocity dispersion of galaxies, sigma_V=1322^+74_-68 kms^-1, which is significantly larger than what is expected in the case of a relaxed cluster with an observed X-ray temperature of 5-6 keV. We find evidence that this cluster is far from dynamical equilibrium, as shown by the non Gaussianity of the velocity distribution, the presence of a velocity gradient and significant substructure. Our analysis shows that the high value of sigma_V is due to the complex structure of RX J0152-1357, i.e. to the presence of three galaxy clumps of different mean velocity. Using optical data we detect a low-velocity clump (with sigma_V=300-500 kms^-1) in the central SW region and a high--velocity clump (with sigma_V sim 700 kms^-1) in the E region, well corresponding to the SW and E peaks detected in the X-ray emission. The central NE X-ray peak is associated to the main galaxy structure with a velocity which is intermediate between those of the other two clumps and sigma_V sim 900 kms^-1. The mass of the whole system within 2 Mpc is estimated to lie in the range (1.2-2.2)X10^{15} M_sun. Analytic calculations based on the two-body model indicate that the system is most likely bound, currently undergoing merging. In particular, we suggest that the SW clump is not a small group, but rather the dense cluster-core of a massive cluster.

description: • Tree range shifts during geohistorical global change events provide a useful real-world model for how future changes in forest biomes may proceed. In North America, during the last deglaciation, the distributions of tree taxa varied significantly in the rate and direction of their responses for reasons that remain unclear. Local-scale processes such as establishment, growth, and resilience to environmental stress ultimately influence range dynamics. Despite the fact that interactions between trees and soil biota are known to influence local-scale processes profoundly, evidence linking belowground interactions to distribution dynamics remains scarce.
• We evaluated climate velocity and plant traits related to dispersal, environmental tolerance, and belowground symbioses, as potential predictors of the geohistorical rates of expansion and contraction of the core distributions of tree genera between 16-7kaBP.
• The receptivity of host genera towards ectomycorrhizal fungi was strongly supported as a positive predictor of poleward rates of distribution expansion, and seed mass was supported as a negative predictor. Climate velocity gained support as a positive predictor of rates of distribution contraction, but not expansion.
• Our findings indicate that understanding how tree distributions, and thus forest ecosystems, respond to climate change requires the simultaneous consideration of traits, biotic interactions, and abiotic forcing.

Mathematical Modeling for Public Health Decision Support During Acute Gastroenteritis Outbreaks

description: Acute gastroenteritis (AGE) outbreaks present a significant challenge to investigating public health officials, who need to know whether point source transmission - such as contaminated food, fomites, or highly infectious individuals - has occurred to respond effectively. However, information on the mode of transmission is frequently unavailable, especially during the early stages of an outbreak when control measures have the greatest impact. Clinical decision support systems (CDS) may be used to assist outbreak investigators when only limited data are available. This dissertation research investigated a) how the guidelines for norovirus outbreaks in healthcare settings vary between state public health agencies across the U.S., b) how mathematical modeling can be used to help outbreak investigators identify potential point source outbreaks, and c) how availability of outbreak information impacts public health decision-making. After introductory material in Chapters 1 and 2, Chapter 3 describes variation in norovirus outbreak guidelines and outcomes between states. Chapter 4 describes the development of a stochastic individual-level mathematical model for predicting whether an outbreak was likely caused by point source transmission. The model's internal and external validity were assessed, and the model was used to estimate potential misclassification in outbreaks reported to have been transmitted person-to-person. Chapter 5 describes semi-structured interviews with AGE epidemiologists about decision-making in hypothetical outbreak scenarios based on different levels of data availability, including results from a CDS based on the mathematical model. There was substantial variation in state healthcare-associated norovirus outbreak response guidelines, and there were differences between states with and without guidelines consistent with national guidance. The model performed well on measures of internal and external validity, and 73% of person-to-person norovirus outbreaks had at least some evidence of point source transmission. AGE epidemiologists drew different conclusions when presented with different levels of information, and there was evidence that CDS could help improve decision-making when only minimal data are available. These results demonstrate the need for CDS for transmission mode classification, the effectiveness of mathematical modeling for outbreak response decision support in some circumstances, and the potential for CDS to improve decision-making when data are sparse and public health action is required.

description: We have developed a new, very efficient numerical scheme to solve the CR diffusion convection equation that can be applied to the study of the nonlinear time evolution of CR modified shocks for arbitrary spatial diffusion properties. The efficiency of the scheme derives from its use of coarse-grained finite momentum volumes. This approach has enabled us, using $\sim 10 - 20$ momentum bins spanning nine orders of magnitude in momentum, to carry out simulations that agree well with results from simulations of modified shocks carried out with our conventional finite difference scheme requiring more than an order of magnitude more momentum points. The coarse-grained, CGMV scheme reduces execution times by a factor approximately half the ratio of momentum bins used in the two methods. Depending on the momentum dependence of the diffusion, additional economies in required spatial and time resolution can be utilized in the CGMV scheme, as well. These allow a computational speed-up of at least an order of magnitude in some cases.

description: Institutions increasingly use first-generation categorizations to provide support to students. In this study, we sought to understand how students make meaning of their first-generation status by conducting a series of focus groups with 54 participants. Our findings reveal that students saw first-generation status as an organizational and familial identity rather than a social identities. This status was connected to alterity and social distance that was most salient in comparison to continuing-generation peers. Our recommendations include re-examining the role of first- generation specific programming on campus, creating opportunities for meaning-making, supporting students within changing family dynamics, and exploring the interaction between first-generation status and other marginalized identities.

description: Rare weak decays of $η^\prime\to Kπ$ have been investigated in the framework of the $U(3)$ chiral perturbation theory at the leading order. Our study shows that the branching ratio ${\cal B}(η^\prime\to Kπ)$ is of the order of $10^{-11}$, which is far below the present experimental upper bound given by the BESIII Collaboration. By further analysis of $η^\prime\to K^+π^-$ and $η^\prime\to K^0π^0$, the ratio of isospin amplitudes is found that $|A_{1/2}/A_{3/2}|\simeq 35$, which supports that the $ΔI=1/2$ transition enhancement, namely, the $ΔI=1/2$ rule, could be functional in $η^\prime$ weak decays.

description: After an introduction on the peculiarities of flavor-physics measurements at a hadron collider, and on the upgraded Collider Detector at Fermilab (CDF II), I show recent results on two-body B0 and B0s decays into charged, pseudo-scalar, charmless mesons or into muons, to illustrate how the flavor physics program at CDF is competitive with (in B0 decays) and complementary (in B0s decays) to B-factories. Results shown include the new measurement of the CP-violating asymmetry in B0-->K+pi- decays, the first measurement of the time-evolution of B0s-->K+K- decays, and the world best limits on the decay rates of rare B0/B0s-->mu+mu- modes.

description: We find evidence for a strong thermal inversion in the dayside atmosphere of the highly irradiated hot Jupiter WASP-18b (T$_{eq}=2411K$, $M=10.3M_{J}$) based on emission spectroscopy from Hubble Space Telescope secondary eclipse observations and Spitzer eclipse photometry. We demonstrate a lack of water vapor in either absorption or emission at 1.4$μ$m. However, we infer emission at 4.5$μ$m and absorption at 1.6$μ$m that we attribute to CO, as well as a non-detection of all other relevant species (e.g., TiO, VO). The most probable atmospheric retrieval solution indicates a C/O ratio of 1 and a high metallicity (C/H=$283^{+395}_{-138}\times$ solar). The derived composition and T/P profile suggest that WASP-18b is the first example of both a planet with a non-oxide driven thermal inversion and a planet with an atmospheric metallicity inconsistent with that predicted for Jupiter-mass planets at $>2σ$. Future observations are necessary to confirm the unusual planetary properties implied by these results.

description: A sample of hundreds of simulated galaxy clusters is used to study the statistical properties of galaxy cluster formation. Individual assembly histories are discussed, the degree of virialization is demonstrated and various commonly used formation times are measured and inter-compared. In addition, the fraction of clusters which have ``recently'' undergone a major merger or significant mass jump is calculated as a function of lookback time and interval. The fraction of three- and four-body mergers is also studied.

description: We compare the performance of various quantum key distribution (QKD) systems using a novel single-photon detector, which combines frequency up-conversion in a periodically poled lithium niobate (PPLN) waveguide and a silicon avalanche photodiode (APD). The comparison is based on the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984 (BB84), the Bennett, Brassard, and Mermin 1992 (BBM92), and the coherent differential phase shift keying (DPSK). We show that the up-conversion detector allows for higher communication rates and longer communication distances than the commonly used InGaAs/InP APD for all the three QKD protocols.

A new subgrid characteristic length for turbulence simulations on anisotropic grids

description: Direct numerical simulations of the incompressible Navier-Stokes equations are not feasible yet for most practical turbulent flows. Therefore, dynamically less complex mathematical formulations are necessary for coarse-grained simulations. In this regard, eddy-viscosity models for Large-Eddy Simulation (LES) are probably the most popular example thereof. This type of models requires the calculation of a subgrid characteristic length which is usually associated with the local grid size. For isotropic grids this is equal to the mesh step. However, for anisotropic or unstructured grids, such as the pancake-like meshes that are often used to resolve near-wall turbulence or shear layers, a consensus on defining the subgrid characteristic length has not been reached yet despite the fact that it can strongly affect the performance of LES models. In this context, a new definition of the subgrid characteristic length is presented in this work. This flow-dependent length scale is based on the turbulent, or subgrid stress, tensor and its representations on different grids. The simplicity and mathematical properties suggest that it can be a robust definition that minimizes the effects of mesh anisotropies on simulation results. The performance of the proposed subgrid characteristic length is successfully tested for decaying isotropic turbulence and a turbulent channel flow using artificially refined grids. Finally, a simple extension of the method for unstructured meshes is proposed and tested for a turbulent flow around a square cylinder. Comparisons with existing subgrid characteristic length scales show that the proposed definition is much more robust with respect to mesh anisotropies and has a great potential to be used in complex geometries where highly skewed (unstructured) meshes are present.
