Membrane Inlet Mass Spectrometry Method (Reox/Mims) To Measure 15n-Nitrate In Isotope-Enrichment Experiments, Xianbiao Lin, Kaijun Lu, Amber K. Hardison, Et Al Jul 2021

Membrane Inlet Mass Spectrometry Method (Reox/Mims) To Measure 15n-Nitrate In Isotope-Enrichment Experiments, Xianbiao Lin, Kaijun Lu, Amber K. Hardison, Et Al

VIMS Articles

Using 15N stable isotope as a tracer to quantify N transformation rates in isotope-enrichment experiments improves understanding of the N cycle in various ecosystems. However, measuring 15N-nitrate (15NO3) in small volumes of water for these experiments is a major challenge due to the inconvenience of preparing samples by traditional techniques. We developed a “REOX/MIMS” method by applying membrane inlet mass spectrometry (MIMS) to determining 15NO3 concentrations in a small volumes of water from isotope-enrichment experiments after converting the dissolved inorganic N to N2. The nitrates (NO3 + NO2) were reduced to ...


Performance Implications Of Memory Affinity On Filesystem Caches In A Non-Uniform Memory Access Environment, Jacob Adams May 2021

Performance Implications Of Memory Affinity On Filesystem Caches In A Non-Uniform Memory Access Environment, Jacob Adams

Undergraduate Honors Theses

Non-Uniform Memory Access imposes unique challenges on every component of an operating system and the applications that run on it. One such component is the filesystem which, while not directly impacted by NUMA in most cases, typically has some form of cache whose performance is constrained by the latency and bandwidth of the memory that it is stored in. One such filesystem is ZFS, which contains its own custom caching system, known as the Adaptive Replacement Cache. This work looks at the impact of NUMA on this cache via sequential read operations, shows how current solutions intended to reduce this ...


Three Centuries Of Vegetation Change In The William & Mary College Woods Reconstructed Using Phytoliths, Timothy Terlizzi May 2021

Three Centuries Of Vegetation Change In The William & Mary College Woods Reconstructed Using Phytoliths, Timothy Terlizzi

Undergraduate Honors Theses

The College Woods, west of William & Mary’s campus, consists of ~900 acres of protected southern mixed hardwood forest. The woods surround Lake Matoaka, a former millpond established in ~1700. Despite the rich history of the area, little is known about how the dominant vegetative landcover has shifted over the last 300 years. This study set out to quantify the modern vegetation within the College Woods via the phytolith assemblages within the soil and identify shifts in the assemblages since the creation of Lake Matoaka and whether these changes are distinct from the vegetation that existed in the area before the lake. To accomplish this, I studied the composition and preservation of phytoliths – silica bodies generated within and between plant cells. The study focused on the two questions: do the modern phytolith assemblages in the soil of the College Woods reflect the vegetation present and can phytoliths within the sediments of Lake Matoaka be used to identify the dominant vegetative communities over the last ~300 years? I addressed these questions with three approaches: 1) Identify the primary phytolith producing taxa within the College Woods; 2) Identify the modern phytolith assemblages within the soil of the College Woods; 3) Identify the differences between phytolith assemblages from the lake sediment core samples. I found the following: 1) The production of phytoliths varies heavily between and within different common taxa of the College Woods, with species of oaks (Quercus spp.) unpredictably producing phytoliths and beeches (Fagus grandifolia) likely contributing the majority of dicot phytoliths; 2) The modern phytolith assemblages of the College Woods reflect a low phytolith producing environment, and the vegetative homogeneity is reflected in the phytolith record; 3) The ...


Scope: Building And Testing An Integrated Manual-Automated Event Extraction Tool For Online Text-Based Media Sources, Matthew Crittenden May 2021

Scope: Building And Testing An Integrated Manual-Automated Event Extraction Tool For Online Text-Based Media Sources, Matthew Crittenden

Undergraduate Honors Theses

Building on insights from two years of manually extracting events information from online news media, an interactive information extraction environment (IIEE) was developed. SCOPE, the Scientific Collection of Open-source Policy Evidence, is a Python Django-based tool divided across specialized modules for extracting structured events data from unstructured text. These modules are grouped into a flexible framework which enables the user to tailor the tool to meet their needs. Following principles of user-oriented learning for information extraction (IE), SCOPE offers an alternative approach to developing AI-assisted IE systems. In this piece, we detail the ongoing development of the SCOPE tool, present ...


Formation Of Oil-Particle-Aggregates: Numerical Model Formulation And Calibration, Linlin Cui, Courtney K. Harris, Danielle R.N. Tarpley May 2021

Formation Of Oil-Particle-Aggregates: Numerical Model Formulation And Calibration, Linlin Cui, Courtney K. Harris, Danielle R.N. Tarpley

VIMS Articles

When oil spills occur in turbid waters, the oil droplets and mineral grains can combine to form oil-particle aggregates (OPAs). The formation of OPAs impacts the vertical transport of both the oil and the mineral grains; especially increasing deposition of oil to the seabed. Though the coastal oceans can be very turbid, to date, few numerical ocean models have accounted for aggregation processes that form OPAs. However, interactions between oil and mineral aggregates may be represented using techniques developed to account for sediment aggregation. As part of Consortium for Simulation of Oil Microbial Interactions in the Ocean (CSOMIO), we modified ...


Composite Gravity In Curved Spacetime, Austin Batz May 2021

Composite Gravity In Curved Spacetime, Austin Batz

Undergraduate Honors Theses

This work presents the development of a quantum theory of gravity motivated by diffeomorphism-invariance and background-independence. A composite graviton state that satisfies the linearized Einstein’s field equations has been identified via perturbative expansion about a curved vacuum spacetime. The emergence of this gravitational interaction is discussed, as well as cancellation of tadpoles and treatment of ultraviolet divergences via dimensional regularization. In other words, the formalism of quantum field theory is used to identify a gravitational interaction as an emergent phenomenon rather than as a fundamental aspect of nature. The lattice is proposed as a candidate for a physical regulator ...


Simulation And Optimization Of Kinematics Measurements For The Moller Parity-Violating Electron-Electron Scattering Experiment, Lauren Carver May 2021

Simulation And Optimization Of Kinematics Measurements For The Moller Parity-Violating Electron-Electron Scattering Experiment, Lauren Carver

Undergraduate Honors Theses

This report describes the optimization of the sieve collimator that will be used for the MOLLER experiment at Jefferson Laboratory. The MOLLER experiment seeks to study the parity-violating asymmetry in electron-electron elastic scattering. For this project, Monte Carlo simulations were run using a GEANT4 simulation package, which includes the main geometry of the proposed experiment, and the essential physics reaction processes. A sieve collimator was added to the simulated geometry. This collimator has pin-hole openings to select scattered electrons at certain locations (radial and azimuthal positions) corresponding to specific scattering angles (theta, and phi). Analysis of the simulated data were ...


“Garden-Magic”: Conceptions Of Nature In Edith Wharton’S Fiction, Jonathan Malks May 2021

“Garden-Magic”: Conceptions Of Nature In Edith Wharton’S Fiction, Jonathan Malks

Undergraduate Honors Theses

I situate Edith Wharton’s guiding idea of “garden-magic” at the center of my thesis because Wharton’s fiction shows how a garden space could naturalize otherwise inadmissible behaviors within upper-class society while helping a character tie such behavior to a greater possibility for escape. To this end, Wharton situates gardens as idealized touchstones within the built environment of New York City, spaces where characters believe they can reach self-actualization within a version of nature that is man-made. Actualization, in this sense, stems from a character’s imaginative escape that is enabled by a perception of the garden as a ...


Topology Of The O(3) Non-Linear Sigma Model Under The Gradient Flow, Stuart Thomas, Christopher Monahan May 2021

Topology Of The O(3) Non-Linear Sigma Model Under The Gradient Flow, Stuart Thomas, Christopher Monahan

Undergraduate Honors Theses

Quantum field theory is an extraordinarily successful framework that describes phenomena in particle physics and condensed matter. The O(3) non-linear sigma model (NLSM) is a specific theory used in both of these fields, describing ferromagnets and acting as a prototype for the strong nuclear force. It features topologically stable configurations known as instantons which cannot continuously evolve to the ground state. The topological susceptibility is a parameter that describes this stability and is predicted to vanish in physical theories, however numerical simulations find that the topological susceptibility diverges in the continuum limit. This issue has motivated the application of ...


Using Machine Learning To Track The Location Of The Shock Train In Hypersonic Engines, Alison Reynolds May 2021

Using Machine Learning To Track The Location Of The Shock Train In Hypersonic Engines, Alison Reynolds

Undergraduate Honors Theses

Proposed hypersonic vehicles would be able to travel at five to ten times the speed of sound, but there are still many problems that need to be solved to construct a functioning vehicle. One such problem involves shocks created in the engine isolator when the vehicle reaches high speeds. These shocks must be contained to the isolator to maximize performance and avoid potential failure. This project attempts to track the location of the leading shock given images of airflow from ground tests of engines using random forests and convolutional neural networks. When the models are trained and tested on data ...


Determining Quantum Symmetry In Graphs Using Planar Algebras, Akshata Pisharody May 2021

Determining Quantum Symmetry In Graphs Using Planar Algebras, Akshata Pisharody

Undergraduate Honors Theses

A graph has quantum symmetry if the algebra associated with its quantum automorphism group is non-commutative. We study what quantum symmetry means and outline one specific method for determining whether a graph has quantum symmetry, a method that involves studying planar algebras and manipulating planar tangles. Modifying a previously used method, we prove that the 5-cycle has no quantum symmetry by showing it has the generating property.


Proteomic Analysis Of Mycobacteriophage Crimd, William Moeller May 2021

Proteomic Analysis Of Mycobacteriophage Crimd, William Moeller

Undergraduate Honors Theses

Bacteriophages represent a large portion of the biomatter on our planet, and many of them have yet to be fully characterized. Here we discuss the proteomic analysis of a particular Bacteriophage, Mycobacteriophage CrimD. This phage was discovered on the Campus of William & Mary and has had its genome characterized. We took the next logical step of proteomic analysis.

In our analyses we made use high pressure liquid chromatography paired with linear ion trap mass spectrometry to analyze the proteome of CrimD at specific time points after the infection of its host, Mycobacterium smegmatis. Additionally, we used nanospray ionization with in-house ...

Vims Ferry Pier Ambient Water Monitoring And Meteorological Data, Six-Minute Data 1986-2003, Gary F. Anderson

Data

Bulk water parameters of Temperature and Salinity were measured at the VIMS Ferry Pier from 1947 to 2003. Initial methods were undocumented but likely automated with an instrument and chart recorder since the data consists of a daily high and low measurement from which a mean value was derived. Beginning in 1986 an Inter-Ocean CTD instrument placed at mid-depth was interfaced to a digital data logger (Campbell Scientific CRJ) that recorded data every six minutes, resulting in 240 measurements per day.

This collection contains only the six-minute data from 1986 through 2003. Weather parameters were also added in 1986 and ...


Mechanisms Driving Decadal Changes In The Carbonate System Of A Coastal Plain Estuary: Associated Dataset, Fei Da, Marjorie A.M. Friedrichs, Pierre St-Laurent Apr 2021

Mechanisms Driving Decadal Changes In The Carbonate System Of A Coastal Plain Estuary: Associated Dataset, Fei Da, Marjorie A.M. Friedrichs, Pierre St-Laurent

Data

This dataset includes model outputs presented in the associated publication (Da et al. 2021, Journal of Geophysical Research: Oceans). This study used a three-dimensional ecosystem model to quantify the relative impacts of multiple anthropogenic drivers on the Chesapeake Bay carbonate system over the past three decades. Model simulations highlight that increased atmospheric CO2 concentrations and decreased terrestrial nutrient inputs are two primary drivers causing nearly equal reductions in pH in surface waters of the Bay.

Impact Assessment And Management Challenges Of Key Rural Human Health Infrastructure Under Sea Level Rise, Molly Mitchell, Robert Isdell, Julie Herman, Christine Tombleson Mar 2021

Impact Assessment And Management Challenges Of Key Rural Human Health Infrastructure Under Sea Level Rise, Molly Mitchell, Robert Isdell, Julie Herman, Christine Tombleson

VIMS Articles

Accelerating sea level rise in Virginia, United States, will significantly increase the flooding threat to low-lying roads, residences, and critical infrastructure as well as raise the water table, allowing saltwater intrusion into well water and threatening the function of septic fields. Although most of the adaptation work in Virginia has focused on urban economic centers, the majority of the coastline is rural and faces different threats and opportunities to address them compared to urban areas due to their reduced economic assets and their reliance on private infrastructure. In this case study, we assess the potential for geospatially quantifying impact to ...


Quantifying Thresholds Of Barrier Geomorphic Change In A Cross-Shore Sediment-Partitioning Model, Daniel J. Ciarletta, Jennifer L. Miselis, Justin L. Shawler, Christopher J. Hein Mar 2021

Quantifying Thresholds Of Barrier Geomorphic Change In A Cross-Shore Sediment-Partitioning Model, Daniel J. Ciarletta, Jennifer L. Miselis, Justin L. Shawler, Christopher J. Hein

VIMS Articles

Barrier coasts, including barrier islands, beach-ridge plains, and associated landforms, can assume a broad spectrum of morphologies over multi-decadal scales that reflect conditions of sediment availability, accommodation, and relative sea-level rise. However, the quantitative thresholds of these controls on barrier-system behavior remain largely unexplored, even as modern sea-level rise and anthropogenic modification of sediment availability increasingly reshape the world's sandy coastlines. In this study, we conceptualize barrier coasts as sediment-partitioning frameworks, distributing sand delivered from the shoreface to the subaqueous and subaerial components of the coastal system. Using an idealized morphodynamic model, we explore thresholds of behavioral and morphologic ...

Development Of The Csomio Coupled Ocean-Oil-Sediment- Biology Model, Dmitry S. Dukhovskoy, Steven L. . Morey, (...), Courtney K. Harris, Et Al

VIMS Articles

The fate and dispersal of oil in the ocean is dependent upon ocean dynamics, as well as transformations resulting from the interaction with the microbial community and suspended particles. These interaction processes are parameterized in many models limiting their ability to accurately simulate the fate and dispersal of oil for subsurface oil spill events. This paper presents a coupled ocean-oil-biology-sediment modeling system developed by the Consortium for Simulation of Oil-Microbial Interactions in the Ocean (CSOMIO) project. A key objective of the CSOMIO project was to develop and evaluate a modeling framework for simulating oil in the marine environment, including its ...

Dissolved ...


Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge - Final Report, Richard A. Snyder, Paige G. Ross Feb 2021

Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge - Final Report, Richard A. Snyder, Paige G. Ross

Reports

Previous sampling of the stream crossing Bobtown Road (Rt 178) near the intersection of Hollies Church Road (Rt. 620), had indicated high levels of nitrogen in the stream flow (Snyder and Ross, 2019a). The proximity of the retired Accomack County Landfill upstream of the site triggered a higher resolution sampling of the stream in an attempt to isolate a source of the nitrogen loading (Snyder and Ross, 2019b). Accomack County has requested repeated sampling of this stream segment to monitor nutrient attenuation trends from the site, and stations were established for that purpose. This Final Report provides a summary of ...


Different Coastal Marsh Sites Reflect Similar Topographic Conditions Under Which Bare Patches And Vegetation Recovery Occur, Chen Wang, Lennert Schepers, Matthew L. Kirwan, Et Al Feb 2021

Different Coastal Marsh Sites Reflect Similar Topographic Conditions Under Which Bare Patches And Vegetation Recovery Occur, Chen Wang, Lennert Schepers, Matthew L. Kirwan, Et Al

VIMS Articles

The presence of bare patches within otherwise vegetated coastal marshes is sometimes considered to be a symptom of marsh dieback and the subsequent loss of important ecosystem services. Here we studied the topographical conditions determining the presence and revegetation of bare patches in three marsh sites with contrasting tidal range, sediment supply, and plant species: the Scheldt estuary (the Netherlands), Venice lagoon (Italy), and Blackwater marshes (Maryland, USA). Based on GIS (geographic information system) analyses of aerial photos and lidar imagery of high resolution (≤2×2 m pixels), we analyzed the topographic conditions under which bare patches occur, including their ...


Coastal Forest Seawater Exposure Increases Stem Methane Concentration, Matthew J. Norwood, Nicholas Ward, (......), Matthew Kirwan, Anya Hopple, J. Patriack Megonigal Feb 2021

Coastal Forest Seawater Exposure Increases Stem Methane Concentration, Matthew J. Norwood, Nicholas Ward, (......), Matthew Kirwan, Anya Hopple, J. Patriack Megonigal

VIMS Articles

Methane (CH4) exchange between trees and the atmosphere has recently emerged as an important, but poorly quantified process regulating global climate. The sources (soil and/or tree) and mechanisms driving the increase of CH4 in trees and degassing to the atmosphere are inadequately understood, particularly for coastal forests facing increased exposure to seawater. We investigated the eco‐physiological relationship between tree stem wood density, soil and stem oxygen saturation (an indicator of redox state), soil and stem CH4 concentrations, soil and stem carbon dioxide (CO2) concentrations, and soil salinity in five forests along the United States ...

Effects Of Reduced Shoreline Erosion On Chesapeake Bay Water Clarity, Jessica S. Turner, Pierre St-Laurent, Marjorie A.M. Friedrichs, Carl T. Friedrichs Jan 2021

Effects Of Reduced Shoreline Erosion On Chesapeake Bay Water Clarity, Jessica S. Turner, Pierre St-Laurent, Marjorie A.M. Friedrichs, Carl T. Friedrichs

VIMS Articles

Shoreline erosion supplies sediments to estuaries and coastal waters, influencing water clarity and primary production. Globally, shoreline erosion sediment inputs are changing with anthropogenic alteration of coastlines in populated regions. Chesapeake Bay, a prime example of such a system where shoreline erosion accounts for a large proportion of sediments entering the estuary, serves here as a case study for investigating the effects of changing sediment inputs on water clarity. Long-term increases in shoreline armoring have contributed to decreased erosional sediment inputs to the estuary, changing the composition of suspended particles in surface waters. This study examined the impact of shoreline ...
