The Impact Of Data Preparation And Model Complexity On The Natural Language Classification Of Chinese News Headlines, Torrey J. Wagner, Dennis Guhl, Brent T. Langhals

Faculty Publications

Given the emergence of China as a political and economic power in the 21st century, there is increased interest in analyzing Chinese news articles to better understand developing trends in China. Because of the volume of the material, automating the categorization of Chinese-language news articles by headline text or titles can be an effective way to sort the articles into categories for efficient review. A 383,000-headline dataset labeled with 15 categories from the Toutiao website was evaluated via natural language processing to predict topic categories. The influence of six data preparation variations on the predictive accuracy of four algorithms was …

"Always Leading Out In That Which Is Great And Good": Mormon Women's Perspective Of Women's Rights Fifty Years After Suffrage, Ashley Anderson Webb

The Thetean: A Student Journal for Scholarly Historical Writing

On a cold Thursday in eartly February 1920, newly enfranchised women from across che nation huddled together in Chicago for a seven-day-long Golden Jubilee. The anticipated passage of the Nineteenth Amendment lay only three scares' ratification and half a year away. That same Thursday, women in Utah looked back half a century co 12 February 1870, when che Utah Territory granted its women the right co vote. While reflecting on their own history, Utah's women also case their eyes outward, joining their sisters throughout the US who looked forward co the future of nationwide suffrage. Many prominent female leaders of …

Cold And Traffic Tolerance Of Hybrid Bermudagrass And Kentucky Bluegrass In A Cool Season, Arid Climate, Caden J. Seely, H. Burgin, N. Hansen, G. Wear, Bryan G. Hopkins

Library/Life Sciences Undergraduate Poster Competition 2024

• Due to climate change, warm-season Hybrid Bermudagrass (HBG) is beginning to be grown in northern climates.
• This is potentially desirable because it may use less water than traditional species.
• However, there is concern regarding winter kill and excessively long dormant periods.
• There is particular interest in HBG with regards to sports turf, but there is concern with its ability to withstand heavy traffic damage when grown in a cool-season climate.

Objective: Assess the cold and traffic tolerance of common Bermudagrass [CBG; Cynodon dactylon (L) Pers.] and seven triploid interspecific hybrids (HBG; Cynodon dactylon × C. transvaalensis Burtt Davy) in …

Library/Life Sciences Undergraduate Poster Competition 2024

• Studied over 2,200 human-bear conflicts in North America and witnessed the shear force that bears can exert to access food and eliminate any threats.
• Polar bears at the Hogle Zoo in Salt Lake City punctured and bent high density polyurethane (HDPE) objects when playing with them.
• This prompted research into the force it takes bears to puncture objects with their canines and claws.

Reproduce Or Live Longer?: A Life History Analysis Of Black Bears In A Semiarid Environment, Brenden M. Orocu, Cambria Armstrong, Janene Auger, Hal L. Black, Randy T. Larsen, Brock R. Mcmillan, Mark C. Belk

Library/Life Sciences Undergraduate Poster Competition 2024

In population demographics, each population has an age stage vital rate (fecundity and survival) in its life history that has the greatest influence on the asymptotic population growth rate, λ.

American black bears (Ursus americanus) are found throughout North America. Other studies on population demographics have focused on populations in higher resource availability areas but none in semiarid environments where resource scarcity is a result of the variable climate.

Objective

Our objective was to determine if factors influencing population dynamics of black bears in semi-arid environments were similar to factors affecting population dynamics in mesic environments where …

A Rare Plant In Peril: Conservation Concerns For An Endemic Alpine Plant, Ipomopsis Spicata Ssp Tridactyla, Kainoa Bolinder, Loreen Allphin, Madison Huie, Steven Flinders

Library/Life Sciences Undergraduate Poster Competition 2024

Ipomopsis spicata ssp. tridactyla, (I. tridactyla or IPTR; Fig. 2 & 12), is a rare alpine plant species endemic to the Tushar Mountains and Markagunt Plateau of southern Utah. There is limited knowledge available about population dynamics and community composition. Due to difficult abiotic conditions, alpine environments are more vulnerable to lasting damage from disturbance (Scherrer & Pickering, 2005). Ipomopsis tridactyla is listed as high-priority for conservation (Alexander, 2016). As conservation concerns for alpine plant communities increase due to climate change (Kopp & Cleland, 2013), so does the need for long-term monitoring of plant populations. Thus, we set …

Advancements in artificial intelligence continue to impact nearly every aspect of human life by providing integration options that aim to supplement or improve current processes. One industry that continues to benefit from artificial intelligence integration is healthcare. For years now, elements of artificial intelligence have been used to assist in clinical decision making, helping to identify potential health risks at earlier stages, and supplementing precision medicine. An area of healthcare that specifically looks at wearable devices, sensors, phone applications, and other such devices is mobile health (mHealth). These devices are used to aid in health data collection and delivery. This …

Quantitative Shotgun Proteomic Analysis Of Bacteria After Overexpression Of Recombinant Spider Miniature Spidroin, Masp1, Kathryn Randene, J. Alexander H. Mendoza, Michael Ysit, Craig Vierra

Pacific Faculty Work

Spider silk has extraordinary mechanical properties, displaying high tensile strength, elasticity, and toughness. Given the high performance of natural fibers, one of the long-term goals of the silk community is to manufacture large-scale synthetic spider silk. This process requires vast quantities of recombinant proteins for wet-spinning applications. Attempts to synthesize large amounts of native size recombinant spidroins in diverse cell types have been unsuccessful. In these studies, we design and express recombinant miniature black widow MaSp1 spidroins in bacteria that incorporate the N-terminal and C-terminal domain (NTD and CTD), along with varying numbers of codon-optimized internal block repeats. Following spidroin …

Estimating Polarization Purity With Noise, Alex Kostinski, Dan Kestner, Jothiram Vivekanandan

Michigan Tech Publications

We formulate a problem of estimating and monitoring mismatch (unwanted departure from orthogonality) of two ostensibly orthogonal polarization channels in a fully polarimetric general device such as a polarimetric weather radar. A statistical approach is proposed by using thermal noise or, more generally, a 'polarimetric noise' class of sources. The suitable noise class of distributions is shown to be rooted in the complex multivariate Gaussian probability density function (pdf), the latter possessing a uniform pdf on the Poincare sphere (PS), with a probability measure given by a fractional surface area. To that end, we develop a parameter to estimate polarization …

The Gyrokinetic Dispersion Relation Of Microtearing Modes In Collisionless Toroidal Plasmas, Benjamin D G Chandran, A A. Schekochihin

Faculty Publications

We solve the linearized gyrokinetic equation, quasineutrality condition and Ampere's law to obtain the dispersion relation of microtearing modes (MTMs) in collisionless low- $\beta$ toroidal plasmas. Consistent with past studies, we find that MTMs are driven unstable by the electron temperature gradient and that this instability drive is mediated by magnetic drifts. The dispersion relation that we derive can be evaluated numerically very quickly and may prove useful for devising strategies to mitigate MTM instability in fusion devices.

The Homotopy Cardinality Of The Representation Category, Justin Murray

LSU Doctoral Dissertations

Given a Legendrian knot in (R^3, ker(dz − ydx)) one can assign a combinatorial invariants called ruling polynomials. These invariants have been shown to recover not only a (normalized) count of augmentations but are also closely related to a categorical count of augmentations in the form of the homotopy cardinality of the augmentation category. In this article, we prove that that the homotopy cardinality of the n-dimensional represen- tation category is a multiple of the n-colored ruling polynomial. Along the way, we establish that two n-dimensional representations are equivalent in the representation category if they are “conjugate homotopic”. We also …

The Return Of Three-Judge Constitutional Courts, Matt Queen

Duke Law Journal

State courts wield the authority to elevate state constitutional protections above those afforded by the U.S. Constitution. That power is great—so great that some legislatures have intervened in constitutional adjudication, purportedly to undermine forum shopping and check a single judge’s influence. Accordingly, North Carolina and Tennessee require that three-judge trial courts hear constitutional challenges to state laws. These courts echo twentieth-century congressional efforts to trim federal courts’ equitable jurisdiction. They also present new and familiar drawbacks spawned by their federal ancestors.

This Note examines these new constitutional courts through several lenses: their historical context, political development, advantages, and drawbacks. Although …

Doubly Charged Dimers And Trimers Of Heavy Noble Gases, Gabriel Schöpfer, Stefan Bergmeister, Milan Ončák, Ianessa Stromberg, Masoomeh Mahmoodi-Darian, Paul Scheier, Olof Echt, Elisabeth Gruber

Faculty Publications

Many doubly charged heteronuclear dimers are metastable or even thermodynamically stable with respect to charge separation. Homonuclear dicationic dimers, however, are more difficult to form. He₂²⁺ was the first noble gas dimer predicted to be metastable and, decades later, observed. Ne₂²⁺ is the only other dicationic noble gas dimer that has been detected so far. Here, we present a novel approach to form fragile dicationic species, by post-ionization of singly charged ions that are embedded in helium nanodroplets (HNDs). Bare ions are then extracted by colliding the HNDs with helium gas. We detect homonuclear doubly charged …

Closing The Gap Between Theory And Practice To Promote Equity In Stem: Coaching Teachers With Udl Strategies To Empower Students, Debbie Langone

Theses & Dissertations

U.S. schools have witnessed educational reforms that have shifted science curriculum and pedagogy within classrooms. Yet, all these reforms have failed to reduce the racial and gender gaps in STEM fields. In 2016, New York State implemented the New York State Science Learning Standards (NYSSLS) to address these gaps. Problems remain, however, with the NYSSLS standards. The NYSSLS do not offer teachers pedagogical practices with regards to implementation. Students are expected to engage in practices as they emulate scientists, without any direction for teachers to support students through these practices, and they exemplify a deficit mindset by placing the blame …

Coastal Flooding Under Climate Change: Can Machine Learning Help?, Giovanni Coco

Sustainability Seminar Series

Sea-level rise is a consequence of climate change and the main driver of increasing coastal flooding over the twenty-first century. This presentation describes recent developments in downscaled wave climate, storm surge and sea-level rise modelling for Aotearoa New Zealand to project extreme total water. We assume that future total water levels can be calculated through the summation of tides, storm surge, wave runup and sea-level rise, allowing to investigate future overwash potential. Additionally, the presentation will explore how 'machine learning' techniques can enhance our studies, leading to better predictions and reduced uncertainty in understanding coastal flooding.

The Basel Problem And Summing Rational Functions Over Integers, Pranjal Jain

Rose-Hulman Undergraduate Mathematics Journal

We provide a general method to evaluate convergent sums of the form ∑_{k∈Z} R(k) where R is a rational function with complex coefficients. The method is entirely elementary and does not require any calculus beyond some standard limits and convergence criteria. It is inspired by a geometric solution to the famous Basel Problem given by Wästlund (2010), so we begin by demonstrating the method on the Basel Problem to serve as a pilot application. We conclude by applying our ideas to prove Euler’s factorisation for sin x which he originally used to solve the Basel Problem.

Silvopastoral Agroforestry In Upland And Lowland Uk Grassland: Tree Growth And Animal Performance, W R. Eason, R Lavender, R O. Clements, C Duller, E Gill, M Hislop

IGC Proceedings (1977-2023)

Trees, individually protected from herbivore damage using plastic shelters, were planted at two densities (100 and 400 stems/ha) into sheepgrazed pasture in upland and lowland UK grassland sites in 1988. Tree and animal performance were compared with conventional forestry (no sheep) and pasture (no tree) systems. Effects on tree growth and survival are highly species and site dependent although some treatment effects did emerge. Tree shelters encouraged rapid early height growth compared to forestry controls although in some cases tree form was also adversely affected. Generally tree performance within agroforestry treatments was better at the higher planting density. Eight years …
