Incorporation of polymorphic spacers to inhibit sintering of SrO/SrCO3 for thermochemical energy storage

Creator:: Tran, Justin T
Abstract:: Global energy needs are continuously increasing while fossil fuels remain an uncertain resource. With a growing population and demand for energy, alternative energy sources are being pursued to power the future. Fossil fuels are an unsustainable resource that brings along problems of climate change and atmospheric pollution. Concentrated solar power...

Peptide Non-planarity Regained

Creator:: Biel, Justin T.
Abstract:: The planar peptide model has guided our understanding and interpretation of protein crystal structures since its origin in the 1950s. It is well understood that deviations from this model occur, but the majority of peptides are planar, as measured by the standard omega torsion angle. Here, we report the first...

Nonlinear Plates Interacting with A Subsonic, Inviscid Flow via Kutta-Joukowski Interface Conditions

Creator:: Lasiecka, Irena and Webster, Justin T.
Abstract:: We analyze the well-posedness of a flow-plate interaction considered in [22, 24]. Specifically, we consider the Kutta-Joukowski boundary conditions for the flow [20, 28, 26], which ultimately give rise to a hyperbolic equation in the half-space (for the flow) with mixed boundary conditions. This boundary condition has been considered previously...

Decay rates to equilibrium for nonlinear plate equations with degenerate, geometrically-constrained damping

Creator:: Geredeli, Pelin G. and Webster, Justin T.
Abstract:: We analyze the convergence to equilibrium of solutions to the nonlinear Berger plate evolution equation in the presence of localized interior damping (also referred to as geometrically constrained damping). Utilizing the results in [24], we have that any trajectory converges to the set of stationary points N. Employing standard assumptions...

Evolution Semigroups in Supersonic Flow-Plate Interactions

Creator:: Chueshov, Igor, Lasiecka, Irena, and Webster, Justin T.
Abstract:: We consider the well-posedness of a model for a flow-structure interaction. This model describes the dynamics of an elastic flexible plate with clamped boundary conditions immersed in a supersonic flow. A perturbed wave equation describes the flow potential. The plateʼs out-of-plane displacement can be modeled by various nonlinear plate equations...

The effects of flow and stream characteristics on the variation in freshwater mussel growth in a Southeast US river basin

Creator:: Dycus, Justin C., Wisniewski, Jason M., and Peterson, James T.
Abstract:: 1. The evaluation of the age and growth of animal populations is essential for understanding and predicting how populations will respond to changes in environmental conditions and anthropogenic stressors. 2. We used a novel, von Bertalanffy hierarchical modelling approach to quantify relationships between the growth of three freshwater mussel species...

Smooth attractors of finite dimension for von Karman evolutions with nonlinear frictional damping localized in a boundary layer

Creator:: Geredeli, Pelin G., Lasiecka, Irena, and Webster, Justin T.
Abstract:: In this paper dynamic von Karman equations with localized interior damping supported in a boundary collar are considered. Hadamard well-posedness for von Karman plates with various types of nonlinear damping are well known, and the long-time behavior of nonlinear plates has been a topic of recent interest. Since the von...

Creator:: Levine, Pamela J., Elman, Miriam R., Kullar, Ravina, Townes, John M., Bearden, David T., Vilches-Tran, Rowena, McClellan, Ian, and McGregor, Jessina C.
Abstract:: Background: Epidemiologic studies of skin and soft tissue infections (SSTIs) depend upon accurate case identification. Our objective was to evaluate the positive predictive value (PPV) of electronic medical record data for identification of SSTIs in a primary care setting. Methods: A validation study was conducted among primary care outpatients in...

Changes in hyporheic exchange flow following experimental wood removal in a small, low-gradient stream

Creator:: Wondzell, Steven M., LaNier, Justin, Haggerty, Roy, Woodsmith, Richard D., and Edwards, Richard T.
Abstract:: We investigated the response of hyporheic exchange flow (HEF) to wood removal in a small, low-gradient, gravel bed stream in southeast Alaska using a series of groundwater models built to simulate HEF for the initial conditions immediately after wood removal and 1 month, 2 years, 4 years, and 16 years...

Assessing the effectiveness of riparian restoration projects using Landsat and precipitation data from the cloud-computing application ClimateEngine.org

Creator:: Hausner, Mark B., Huntington, Justin L., Nash, Caroline, Morton, Charles, McEvoy, Daniel J., Pilliod, David S., Hegewisch, Katherine C., Daudert, Britta, Abatzoglou, John T., and Grant, Gordon
Abstract:: Riparian vegetation along streams provides a suite of ecosystem services in rangelands and thus is the target of restoration when degraded by over-grazing, erosion, incision, or other disturbances. Assessments of restoration effectiveness depend on defensible monitoring data, which can be both expensive and difficult to collect. We present a method...

The Rise of the Mesopredator

Creator:: Prugh, Laura R., Stoner, Chantal J., Epps, Clinton W., Bean, William T., Ripple, William J., Laliberte, Andrea S., and Brashares, Justin S.
Abstract:: Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,” this trophic interaction has been recorded across a range of...

Abstract:: Human alterations to nutrient cycles[superscript 1,2] and herbivore communities³⁻⁷ are affecting global biodiversity dramatically². Ecological theory predicts these changes should be strongly counteractive: nutrient addition drives plant species loss through intensified competition for light, whereas herbivores prevent competitive exclusion by increasing ground-level light, particularly in productive systems[superscript 8,9]. Here we...

Abstract:: Exotic species dominate many communities; however the functional significance of species’ biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, systematic data assessing the relationship between species provenance, function and response to perturbations. We examined the abundance of native and exotic plant...

Abstract:: Invasions have increased the size of regional species pools, but are typically assumed to reduce native diversity. However, global-scale tests of this assumption have been elusive because of the focus on exotic species richness, rather than relative abundance. This is problematic because low invader richness can indicate invasion resistance by...
