Directly Photoexcited Dirac And Weyl Fermions In Zrsis And Nbas, Christopher P. Weber, Leslie M. Schoop, Stuart S. P. Parkin, Robert C. Newby, Alex Nateprov, Bettina Lotsch, Bala Murali Krishna Mariserla, J. Matthew Kim, Keshav M. Dani, Hans A. Bechtel, Ernerst Arushanov, Mazhar Ali

Physics

We report ultrafast optical measurements of the Dirac line-node semimetal ZrSiS and the Weyl semimetal NbAs, using mid-infrared pump photons from 86 meV to 500 meV to directly excite Dirac and Weyl fermions within the linearly dispersing bands. In NbAs, the photoexcited Weyl fermions initially form a non-thermal distribution, signified by a brief spike in the differential reflectivity whose sign is controlled by the relative energy of the pump and probe photons. In ZrSiS, electron-electron scattering rapidly thermalizes the electrons, and the spike is not observed. Subsequently, hot carriers in both materials cool within a few picoseconds. This cooling, as …

Predictors Of Success On The National Physical Therapy Licensure Examination, Kristie E. Vinson

Student Theses and Dissertations

This study examined the relationship of the scores on the Practice Exam & Assessment Tool (PEAT) to the scaled scores on the National Physical Therapy Examination (NPTE). A correlation analysis examined the relationship of the exam scores from three cohorts of Doctor of Physical Therapy (DPT) students on the PEAT and NPTE. This study sought to determine if the performance on the PEAT was a predictor of first-time pass rate on the NPTE. It was expected that PEAT scores would have a positive correlation to the NPTE scores. The results indicated a moderate to strong correlation between overall PEAT scores …

Actuarial Senescence In A Dimorphic Bird: Different Rates Of Ageing In Morphs With Discrete Reproductive Strategies, M. L. Grunst, A. S. Grunst, Vincent A. Formica, M. L. Korody, A. M. Betuel, M. Barcelo-Serra, R. A. Gonser, E. M. Tuttle

Biology Faculty Works

It is often hypothesized that intra-sexual competition accelerates actuarial senescence, or the increase in mortality rates with age. However, an alternative hypothesis is that parental investment is more important to determining senescence rates. We used a unique model system, the white-throated sparrow (Zonotrichia albicollis), to study variation in actuarial senescence. In this species, genetically determined morphs display discrete mating strategies and disassortative pairing, providing an excellent opportunity to test the predictions of the above hypotheses. Compared to tan-striped males, white-striped males are more polygynous and aggressive, and less parental. Tan-striped females receive less parental support, and invest more into parental …

New Directions In Justification Logic, Joseph Lurie

Doctoral Dissertations

Justification logics are constructive analogues of modal logics. As such, they provide perspicuous models of those modalities that have inherently constructive character, such as intuitionistic mathematical provability or the knowledge operator of evidentialist epistemology. In this dissertation, I examine a variety of positions in epistemology, along with their associated ontological commitments, and develop various classical and non-classical justification logics that are suitable for use as models of these positions.

Molecular Fossils From Phytoplankton Reveal Secular Pco2 Trend Over The Phanerozoic, Caitlyn R. Witkowski, Johan W. H. Weijers, Brian S. Blais, Stefan Schouten, Jaap S. Sinninghe Damsté

Science and Technology Department Faculty Journal Articles

Past changes in the atmospheric concentration of carbon dioxide (PCO2) have had a major impact on earth system dynamics; yet, reconstructing secular trends of past PCO2 remains a prevalent challenge in paleoclimate studies. The current long-term PCO2reconstructions rely largely on the compilation of many different proxies, often with discrepancies among proxies, particularly for periods older than 100 million years (Ma). Here, we reconstructed Phanerozoic PCO2 from a single proxy: the stable carbon isotopic fractionation associated with photosynthesis (Ɛp) that increases as PCO2 increases. This concept has been widely applied to alkenones, but here, we …

Volunteering At Hyde Park Middle School, Justice Williams

First-Year Seminar Posters (COE 102/103)

The main social issue addressed at Hyde Park Middle School is education. The students attend school to get an education and learn, and the teachers went to college so they would be qualified to teach. However, when students other needs are not meet, they will not focus on their education. This is why the school does what they can to address other issues that the students may be experiencing. They provide free and reduced breakfast and lunches for students who cannot necessarily afford to eat otherwise. This makes it so they can focus on the lessons rather than their hunger. …

Transfer Learning With Deep Recurrent Neural Networks For Remaining Useful Life Estimation, Ansi Zhang, Honglei Wang, Shaobo Li, Yuxin Cui, Guanci Yang, Jianjun Hu

Faculty Publications

Prognostics, such as remaining useful life (RUL) prediction, is a crucial task in condition-based maintenance. A major challenge in data-driven prognostics is the difficulty of obtaining a sufficient number of samples of failure progression. However, for traditional machine learning methods and deep neural networks, enough training data is a prerequisite to train good prediction models. In this work, we proposed a transfer learning algorithm based on Bi-directional Long Short-Term Memory (BLSTM) recurrent neural networks for RUL estimation, in which the models can be first trained on different but related datasets and then fine-tuned by the target dataset. Extensive experimental results …

High-Throughput Assessment Of A Novel, Thiol-Acrylate Hydrogel For Tumor Spheroid Synthesis In A Microfluidic Device, Nathan Daniel Kersker

LSU Master's Theses

The extracellular environment plays an important role in regulating cell behavior. The mechanical, structural, and compositional properties of the extracellular matrix can determine the fate of the growing cells. Standard two-dimensional culturing in a flask fails to represent a native cellular environment. To create the native environment suitable for cells, hydrogels were previously studied. One of the most extensively studied synthetic hydrogels was a poly(ethylene glycol diacrylate) (PEGDA) hydrogel. However, the need for UV polymerization may introduce unwanted changes in cell morphology and viability. The hydrogel being proposed was a form of a thiol-acrylate hydrogel that can eliminate this problem …

A Case Study Of Student And Staff Perceptions Of The School Breakfast Program: Food For Thought From A College Preparatory High School For Underserved Students, Jennifer Lucas Young

Dissertations and Theses

Research suggests that participation in the School Breakfast Program positively impacts academic success by improving student behavior, cognitive functioning, and attendance. Additionally, the School Breakfast Program appears to improve food insecurity, overall health and weight-related issues. However, compared to the National School Lunch Program, participation in the School Breakfast Program has been historically low, especially at the high school level. Using an integrated composite framework, a combination of social cognitive theory and ecological systems theory, as the conceptual model, this qualitative case study explored factors influencing student breakfast eating and participation in the school's breakfast program within a college-preparatory high …

Food and Machinery

Finite element model of waist mounting bracket of MD-1200YJ palletizing robot was established, and the accuracy of the finite element model was verified by modal analysis, the modal test, and static analysis. Taking dynamic factors into account, based on the quintic non-uniform, the rational B-splines motion law was carried out, and the analysis showed that this part had the potential of lightweight design. The mass, the maximal stress, and the maximal deformation were minimized as the optimization objectives were determined. The structure parameters as design variables, the first and second natural frequency no reducing and boundary conditions of design variables …

Expanding Capacity To Serve Multilingual Learners: A University-School District Partnership, Beth Clark-Gareca, Kim Fontana

Excelsior: Leadership in Teaching and Learning

In a time of new teacher certification requirements in New York, school districts are grappling with how to meet the regulatory expectations imposed by Commissioner’s Regulations Part 154. One way that schools are solving staffing challenges is by forging new collaborations with university partners to expand their collective capacities to serve Multilingual learners (MLLs). In this article, we document a partnership between SUNY New Paltz’s Teaching English to Speakers of Other Languages (TESOL) program and the Pawling Central School District during the 2017-18 academic year. We describe the partners’ distinct roles in the university-district collaboration, and discuss the logistical considerations …

How Do Polar Ice Sheets And Sea Level Behave Under A Changing Climate?, Sandra Passchier

Sustainability Seminar Series

Nearly 3 billion people live within 100 km of the coastline, many in large urban centers. In predictions of sea level rise, the future role of polar ice sheets is one of the most critical uncertainties under the present extreme rise in greenhouse forcing of the climate system. This talk will show how geoscientists address the Earth system processes involved in melting ice sheets under warmer climates, and introduce the objectives of an upcoming deepsea drilling expedition to the area with greatest ice loss in West Antarctica.

Observing Soil Changes Under Common Cropping Practices In Kentucky, Samantha Peterson, Iin Handayani, Alyx Shultz Dr, Brian Parr

Posters-at-the-Capitol

Cropping production and tillage systems lead to loss of soil organic matter (SOM), lowering soil pH, and soil compaction in Kentucky. However, the magnitude of the changes varied among the soil properties. Therefore, the objective of this research was to evaluate the changes in SOM, soil pH, and soil compaction under different cropping systems like corn-soybean-tobacco rotation (Field #1), continuous corn field (Field #2), hemp field (Field #3), wheat field (Field #4), pasture with animal grazing (Field #5), and canola field (Field #6). The prominent soil textures in all fields are silt loam and silty clay loam. Disturbed soil samples …

Exploring Echo-Systems: How Algorithms Shape Immersive Media Environments, James N. Cohen

Journal of Media Literacy Education

In the lead up to the 2016 election, fake news often “outperformed” actual news in users’ social media feeds (Silverman, 2016). This paper attempts to analyze the process in which fake news proliferates social networking sites and presents a method of understanding and articulating ways in which personalized feeds are shaped by algorithm-based user feedback. The algorithm systems are embedded programs that analyze past user data and search history in combination with other users’ searches and history to calculate digital outcomes, anticipate possible recommendations, and present consumers with feeds that represent their own unique immersive media environments.

Fake Or Visual Trickery? Understanding The Quantitative Visual Rhetoric In The News, Rohit Mehta, Lynette Deaun Guzmán

Journal of Media Literacy Education

In online and video/television spaces, news media discourses incorporate multimodal design as a discursive move capable of steering meaning toward desirable implications. Around the 2016 U.S. presidential elections, while polarized news outlets made their positionality on the candidates obvious, more neutral or central news outlets revealed their preferences through subtle multimodal design choices. One of these design choices is using a quantitative visual rhetoric: persuasive multimodal moves that draw on quantification through visual, spatial, and textual manipulation—involving the choice of data representation, visual images, and illustrations, (im)balance between numeric and alphabetic texts, and general quantitative narrative. This quantitative visual rhetoric …

Media Literacy And Climate Change In A Post-Truth Society, James S. Damico, Mark Baildon, Alexandra Panos

Journal of Media Literacy Education

In this article we draw from ecolingusitics (Stibbe, 2015) and a civic media literacy framework (Author, in press; Masyada & Washington, 2016) to consider what happened when three pairs of preservice teachers with different academic backgrounds and climate change beliefs jointly evaluated the reliability of two media sources that make opposing arguments about climate change. An ecolinguistics perspective attends to the environmental impact of the “stories-we-live-by” (Stibbe, 2015) and a civic media literacy lens highlights the centrality of dialogue and deliberation along with critical reading when evaluating the reliability of information sources about complex socioscientific topics like climate change. Our …

Writing With Discipline: A Call For Avoiding Apa Style Guide Errors In Manuscript Preparation, Anthony J. Onwuegbuzie, Julie P. Combs

School Leadership Review

The education community in the United States—as in many countries—is extremely large and diverse. Indeed, as documented by Mosteller, Nave, and Miech (2004),

The United States has more than 3.6 million teachers in elementary and secondary education, more than 100,000 principals, and about 15,000 school districts, each with its own set of district administrators, school board members, and concerned citizens. The parents and family members of the 60 million students in elementary and secondary education represent another constituency, as do the policymakers and legislators in the 50 states (along with the District of Columbia) and at the federal level. Postsecondary …

Use Or Consequences: Probing The Cognitive Difference Between Two Measures Of Divergent Thinking, Richard W. Hass, Roger E. Beaty

College of Humanities and Sciences Faculty Papers

Recent studies have highlighted both similarities and differences between the cognitive processing that underpins memory retrieval and that which underpins creative thinking. To date, studies have focused more heavily on the Alternative Uses task, but fewer studies have investigated the processing underpinning other idea generation tasks. This study examines both Alternative Uses and Consequences idea generation with a methods pulled from cognitive psychology, and a novel method for evaluating the creativity of such responses. Participants were recruited from Amazon Mechanical Turk using a custom interface allowing for requisite experimental control. Results showed that both Alternative Uses and Consequences generation are …
