The Toxoplasma Gondii Cyst Wall Protein Cst1 Is Critical For Cyst Wall Integrity And Promotes Bradyzoite Persistence, Tadakimi Tomita, David J. Bzik, Yan Fen Ma, Barbara A. Fox

Dartmouth Scholarship

Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large …

An Event History Analysis Of Educational Loans And College Graduation: A Focus On Differences By Race And Ethnicity, Min Zhan, Xiaoling Xiang

Center for Social Development Research

This study examines the association between educational loans and college graduation rates, with a focus on differences by race and ethnicity. Data come from the 1997 National Longitudinal Survey of Youth (NLSY97). Results from event history analyses that control for a number of student characteristics, college experiences, and financial resources indicate that educational loans are positively related to the rate of college graduation. Larger loan amounts tend to decrease the likelihood of college graduation. The relationship between educational loans and college graduation is stronger among minority (Black and Hispanic) students. Overall, there is little evidence that educational loans reduce racial …

Timing And Spectroscopy Requirements For A Plastic Scintillating Fiber Bundle Time-Of-Flight Neutron Spectrometer, Paul A. Clement

Theses and Dissertations

The design parameters of a Time-of-Flight (TOF) neutron spectrometer composed of BCF-12 plastic scintillating fibers were investigated. A GEANT4 transport model was developed for analyzing the interaction of 2.5 MeV neutrons with a 14 x 14 BCF-12 fiber bundle. The bundle simulation demonstrated that 0.359% of all neutrons incident on the bundle will double scatter. The timing and data collection e efficiencies of a Tektronix DPO7104 series digital oscilloscope were examined to determine the signal processing requirements for future fiber bundle measurements. The minimum detectable neutron energy was computed by taking into account the bundle scintillation e efficiency, light collection …

Real-Time, Multiple Pan/Tilt/Zoom Computer Vision Tracking And 3d Positioning System For Unmanned Aerial System Metrology, Daniel D. Doyle

Theses and Dissertations

The study of structural characteristics of Unmanned Aerial Systems (UASs) continues to be an important field of research for developing state of the art nano/micro systems. Development of a metrology system using computer vision (CV) tracking and 3D point extraction would provide an avenue for making these theoretical developments. This work provides a portable, scalable system capable of real-time tracking, zooming, and 3D position estimation of a UAS using multiple cameras. Current state-of-the-art photogrammetry systems use retro-reflective markers or single point lasers to obtain object poses and/or positions over time. Using a CV pan/tilt/zoom (PTZ) system has the potential to …

Mems Cantilever Sensor For Thz Photoacoustic Chemical Sensing And Spectroscopy, Nathan E. Glauvitz

Theses and Dissertations

Sensitive Microelectromechanical System (MEMS) cantilever designs were modeled, fabricated, and tested to measure the photoacoustic (PA) response of gasses to terahertz (THz) radiation. Surface and bulk micromachining technologies were employed to create the extremely sensitive devices that could detect very small changes in pressure. Fabricated devices were then tested in a custom made THz PA vacuum test chamber where the cantilever deflections caused by the photoacoustic effect were measured with a laser interferometer and iris beam clipped methods. The sensitive cantilever designs achieved a normalized noise equivalent absorption coefficient of 2.83x10^-10 cm^-1 W Hz^-1/2 using a 25 …

Electronic And Physical Characterization Of Hydrothermally Grown Single Crystal Tho2, Tony D. Kelly Ii

Theses and Dissertations

Actinide single crystals are important to the fabrication of next generation electronic devices that could possibly have radiation with the atmosphere and surroundings. Th02 single crystals were obtained previous to this work by hydrothermal synthesis. As these crystals were the first of their kind, the geometric and electric structure of the crystals needed to be extracted. The valence and conduction bands were studied in order to ascertain the band gap using ultraviolet photoemission spectroscopy (UPS) and inverse photoemission spectroscopy (IPES). The unoccupied structure was further characterized using x-ray absorption near edge structure (XANES) and relativistic, real-space Green's functions calculations. The …

Efficient And Long-Time Accurate Second-Order Methods For The Stokes-Darcy System, Wenbin Chen, Max Gunzburger, Dong Sun, Xiaoming Wan

Mathematics and Statistics Faculty Research & Creative Works

We propose and study two second order in time implicit-explicit methods for the coupled Stokes-Darcy system that governs flows in karst aquifers and other subsurface flow systems. the first method is a combination of a second-order backward differentiation formula and the second order Gear's extrapolation approach. the second is a combination of the second-order Adams-Moulton and second-order Adams-Bashforth methods. Both algorithms only require the solution of decoupled Stokes and Darcy problems at each time-step. Hence, these schemes are very efficient and can be easily implemented using legacy codes. We establish the unconditional and uniform in time stability for both schemes. …

Understanding Human Learning Using A Multiagent Based Unified Learning Model Simulation, Vlad T. Chiriacescu

School of Computing: Dissertations, Theses, and Student Research

Within cognitive science, computational modeling based on cognitive architectures has been an important approach to addressing questions of human cognition and learning. Modeling issues such as limited expressivity in representing knowledge and lack of appropriate selection of model structure represent a challenge for existing architectures. Furthermore, latest research shows that the concepts of long-term memory, motivation and working memory are critical cognitive aspects but a unifying cognitive paradigm integrating those concepts hasn’t been previously achieved.

Derived from a synthesis of neuroscience, cognitive science, psychology, and education, the Unified Learning Model (ULM) provides this integration by merging a statistical learning mechanism …

Utilizing Gis To Examine The Relationship Between State Renewable Portfolio Standards And The Adoption Of Renewable Energy Technologies, Chelsea Schelly, Jessica Price

Department of Social Sciences Publications

In the United States, there is no comprehensive energy policy at the federal level. To address issues as diverse as climate change, energy security, and economic development, individual states have increasingly implemented Renewable Portfolio Standards (RPSs), which mandate that utility providers include a specified amount of electricity from renewable energy sources in their total energy portfolios. Some states have included incentives for individual energy technologies in their RPS, such as solar electric (also called photovoltaic or PV technology). Here, we use GIS to visualize adoption of RPSs and electricity generation from renewable energy sources in the US and examine changes …

Syrian And Palestinian Syrian Refugees In Lebanon: The Plight Of Women And Children, Lorraine Charles, Kate Denman

Journal of International Women's Studies

The humanitarian crisis resulting from the Syrian conflict is estimated to be the worst so far of this century. The recent influx of refugees has now reached a point where they are equal to one quarter of Lebanon’s population, causing evident strains on its fragile economy and social structure. Syrians in Lebanon have fled from their home to seek safety, however their vulnerability is now in question as women’s and children’s rights continue to be under threat. This paper investigates the plight of Syrian and Palestinian Syrian refugees in Lebanon with an emphasis on women and children. While there are …

"We Thought We Were Playing": Children’S Participation In The Syrian Revolution, Layla Saleh

Journal of International Women's Studies

This article explores the participation of children in the Syrian uprising against Bashar al-Assad. The involvement of children in democratic social movements and regime transitions has not been addressed in the literature, although some works describe the role children can play in making public policy or in the humanitarian domain. I argue that just as the role of women and of university-aged youth was gradually incorporated in the body of research on the social movements and regime transitions, so should the role of children be studied. I then characterize the role of children in the Syrian uprising as a three-stage …

Lessons Gleaned From The Political Participation Of Children In Bahrain Uprising, Hae Won Jeong

Journal of International Women's Studies

Reflecting the tension between state sovereignty and human rights, this paper discusses the moral and ethical implications of the political participation and detention of Bahraini children against the backdrop of sectarian geopolitics. Drawing methodological insights from postmodernism, this paper argues that reading of Bahraini children as political subjects are objectified and reified with truth claims, which ascribes them a minoritized status based on age and sect. This paper is interdisciplinary in its approach and is three-pronged: First, it begins by providing a contextual analysis of sectarian politics and dichotomous discourses of national sovereignty and human rights. Secondly, this paper juxtaposes …

Nation, Gender, And Identity: Children In The Syrian Revolution 2011, Manal Al-Natour

Journal of International Women's Studies

This article examines the victimization and role of Syrian children in the Syrian Revolution 2011. I claim that through engaging in a competition to provide a definitive image of the nation, both the regime and the opposition victimize Syrian children. Nevertheless, the art projects undertaken by nonviolence activists have proven to help children heal and to cope with the predicaments brought on them by the crisis. The poetry, paintings, drawings, and songs produced by these children are the best means they have of representing their victimization and their role in the revolution, and communicating their perspectives on the Syrian nation …

Multi-State Models For Natural History Of Disease, Amy Laird, Rebecca A. Hubbard, Lurdes Y. T. Inoue

UW Biostatistics Working Paper Series

Longitudinal studies are a useful tool for investigating the course of chronic diseases. Many chronic diseases can be characterized by a set of health states. We can improve our understanding of the natural history of the disease by modeling the sequence of visited health states and the duration in each state. However, in most applications, subjects are observed only intermittently. This observation scheme creates a major modeling challenge: the transition times are not known exactly, and in some cases the path through the health states is not known.

In this manuscript we review existing approaches for modeling multi-state longitudinal data. …

Spatial Spectrograms Of Vibrating Atomic Force Microscopy Cantilevers Coupled To Sample Surfaces, Ryan Wagner, Arvind Raman, Roger Proksch

Birck and NCN Publications

Many advanced dynamic Atomic Force Microscopy (AFM) techniques such as contact resonance, force modulation, piezoresponse force microscopy, electrochemical strain microscopy, and AFM infrared spectroscopy exploit the dynamic response of a cantilever in contact with a sample to extract local material properties. Achieving quantitative results in these techniques usually requires the assumption of a certain shape of cantilever vibration. We present a technique that allows in-situ measurements of the vibrational shape of AFM cantilevers coupled to surfaces. This technique opens up unique approaches to nanoscale material property mapping, which are not possible with single point measurements alone. (C) 2013 AIP Publishing …
