Carbon Fixation Trends In Eleven Of The World’S Largest Lakes: 2003–2018, Michael Sayers, Karl Bosse, Gary L. Fahnenstiel, Robert Shuchman

Michigan Tech Publications, Part 1

Large freshwater lakes provide immense value to the surrounding populations, yet there is limited understanding of how these lakes will respond to climate change and other factors. This study uses satellite remote sensing to estimate annual, lake-wide primary production in 11 of the world’s largest lakes from 2003–2018. These lakes include the five Laurentian Great Lakes, the three African Great Lakes, Lake Baikal, and Great Bear and Great Slave Lakes. Mean annual production in these lakes ranged from under 200 mgC/m²/day to over 1100 mgC/m²/day, and the lakes were placed into one of three distinct groups …

Finding All ∈-Good Arms In Stochastic Bandits, Blake Mason, Lalit Jain, Ardhendu S. Tripathy, Robert Nowak

Computer Science Faculty Research & Creative Works

The pure-exploration problem in stochastic multi-armed bandits aims to find one or more arms with the largest (or near largest) means. Examples include finding an ∈-good arm, best-arm identification, top-k arm identification, and finding all arms with means above a specified threshold. However, the problem of finding all ∈-good arms has been overlooked in past work, although arguably this may be the most natural objective in many applications. For example, a virologist may conduct preliminary laboratory experiments on a large candidate set of treatments and move all ∈-good treatments into more expensive clinical trials. Since the ultimate clinical efficacy is …

In this paper, an attempt has been made to study the applicability of the Lotka’s law to the publications of horticulture scientists in BCKV …

Library Usage By Faculty Members Of Benguet State University, Noel W. Cabfilan, Marjorie C. Ricardo

Library Philosophy and Practice (e-journal)

The study's objectives were to determine Benguet State University faculty members' general impression of the library resources and their usage of these resources. To answer these objectives, questions on faculty members' satisfaction with the library resources, frequency of usage, purposes of using the library resources, reasons for not using the library resources, reasons of not being able to find the resources they are looking for in the library and suggestions for library development in terms of library resources were asked.

It was found out that the majority of the faculty members have used the library resources at least once-a-term. On …

Exponential And Hypoexponential Distributions: Some Characterizations, George Yanev

School of Mathematical & Statistical Sciences Faculty Publications

The (general) hypoexponential distribution is the distribution of a sum of independent exponential random variables. We consider the particular case when the involved exponential variables have distinct rate parameters. We prove that the following converse result is true. If for some n ≥ 2, X1, X2, . . . , Xn are independent copies of a random variable X with unknown distribution F and a specific linear combination of Xj ’s has hypoexponential distribution, then F is exponential. Thus, we obtain new characterizations of the exponential distribution. As corollaries of the main results, we extend some previous characterizations established recently …

Assessing Perceptions Of Group Work Using Team-Based Learning, Lauren Ferry, Phillip J. Wong, Kathryn Hogan

James Madison Undergraduate Research Journal (JMURJ)

Group work is frequently incorporated into courses; however, student perceptions of their experiences and the benefits of group work might differ based on the structure of course. In this study, we examined student perceptions of group work in a team-based learning (TBL) course. Undergraduate students completed pre- and post-surveys on their team work experiences over a semester. Students had lower agreement with the statement “working in groups usually ends up with one person doing all of the work” and higher agreement with “working in a group makes me feel as though I am part of a learning community” at post-test. …

Better News About Math: A Research Agenda, Jay Barchas-Lichtenstein, John Voiklis, Laura Santhanam, Nsikan Akpan, Shivani Ishwar, Bennett Attaway, Patti Parson, John Fraser

Numeracy

Numeracy is not a luxury: numbers constantly factor into our daily lives. Yet adults in the United States have lower numeracy than adults in most other developed nations. While formal statistical training is effective, few adults receive it – and schools are a major contributor to the inequity we see among U.S. adults. That leaves news well-poised as a source of informal learning, given that news is a domain where adults regularly encounter quantitative content. Our transdisciplinary team of journalists and social scientists propose a research agenda for thinking about math and the news. We engage here in a dialogue …

Effect Of Flour Type On Sourdough Starters, Irene (Sooah) Park, Kenith Taukolo '23

Methods in Scientific Inquiry

After deciding on world hunger as our topic for our Methods in Scientific Inquiry (MSI) project, we decided to conduct an experiment about sourdough starters. In particular, we were asking how the type of flour (ie, whole wheat and all-purpose) may affect the rise of sourdough starters. The differences in height in the different types of sourdough starters using whole wheat and all-purpose flour were identified. We used paired t-tests for deciding if the heights of the starters grew overtime and a two-sample t-test to find if the mean change in height was statistically significant between the different types of …

By controlling instrumental errors to below 10 cm s−1, the EXtreme PREcision Spectrograph (EXPRES) allows for a more insightful study of photospheric velocities that can mask weak Keplerian signals. Gaussian processes (GP) have become a standard tool for modeling correlated noise in radial velocity data sets. While GPs are constrained and motivated by physical properties of the star, in some cases they are still flexible enough to absorb unresolved Keplerian signals. We apply GP regression to EXPRES radial velocity measurements of the 3.5 Gyr old chromospherically active Sun-like star, HD 101501. We obtain tight constraints on the stellar rotation period …

The Bay Area Rail System: A Sustainable Network Or A Social Equity Phenomenon?, Whitney Libunao

Master's Projects and Capstones

Sustainable transportation, as it relates to sustainable development, aims to achieve economic stability, social equity, and environmental preservation via transit projects. However, gentrification processes and transit-oriented developments or TODs have attracted more households inward toward reinvested transit-centric areas. The San Francisco Bay Area, California has continued to see positive economic growth, with that, higher-income households inhabiting more centralized locations. Native low-income residents have started to feel displacement pressures on both a social and economic scale. Over time, displacement risk inevitably leads to residential displacement where low-income families are forced to relocate to distant, more affordable neighborhoods. As more distance separates …

The anaphase-promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase and critical regulator of cell cycle progression. Despite its vital role, it has remained challenging to globally map APC/C substrates. By combining orthogonal features of known substrates, we predicted APC/C substrates in silico. This analysis identified many known substrates and suggested numerous candidates. Unexpectedly, chromatin regulatory proteins are enriched among putative substrates, and we show experimentally that several chromatin proteins bind APC/C, oscillate during the cell cycle, and are degraded following APC/C activation, consistent with being direct APC/C substrates. Additional analysis revealed detailed mechanisms of ubiquitylation for UHRF1, a key chromatin …

Synthesis Of The Oxidative Metabolites Of Di(2-Ethylhexyl) Phthalate And Analysis Of Metabolite Binding With Peroxisome Proliferator-Activated Receptors, Alexis Brooner

Departmental Honors & Graduate Capstone Projects

Di(2-ethylhexyl) phthalate (DEHP) is a persistent organic pollutant that is added to increase the flexibility of soft plastics, such as polyvinyl chloride (PVC). Since DEHP is not bound to the polymer, it leaches into the environment, leading to human exposure. When DEHP is metabolized by the body, it is cleaved into mono-(2-ethylhexyl) phthalate (MEHP). MEHP is then oxidized to produce the secondary-oxidized metabolites mono-(2-ethyl-5-carboxypentyl)phthalate (5cx-MEPP), mono-(2-ethyl-5-oxohexyl)phthalate (5oxo-MEHP), and mono-[2-(carboxymethyl)hexyl]phthalate (2cx-MMHP). DEHP and its metabolites interact with peroxisome proliferator-activated receptors (PPARs), which can alter lipid metabolism. To synthesize 5cx-MEHP, an enolate alkylation was performed with ethyl butyrate to form ethyl 2-ethyl-6-heptenoate. …

Niche Dynamics Of The Felid Guild Following The Pleistocene Megafaunal Extinction, Nicholas A. Freymueller

Biology ETDs

The loss of large carnivores is fundamentally restructuring modern mammal communities. However, large carnivore removal is not exclusively a modern trend. The Pleistocene Megafaunal Extinction (PME) resulted in a near-eradication of hyper-carnivorous felids such as saber-toothed cats. However, it is unclear if smaller surviving meso-felids began to infill this ecological vacuum post-PME. I apply Ecological Niche Modeling (ENM) to test evaluate whether surviving felids filled in vacant niches post-extinction, and hypothesize that they ought to have shown increased niche-overlap patterns with mega-felids post-extinction. I model species’ fundamental niches using a multi-temporal approach, and develop a novel test to model realized …

Large Global Variations In Measured Airborne Metal Concentrations Driven By Anthropogenic Sources, Jacob Mcneill, Randal V. Martin, Nofel Lagrosas, 35 Co-Authors

SOSE Affiliate: Manila Observatory

Globally consistent measurements of airborne metal concentrations in fine particulate matter (PM_2.5) are important for understanding potential health impacts, prioritizing air pollution mitigation strategies, and enabling global chemical transport model development. PM_2.5 filter samples (N ~ 800 from 19 locations) collected from a globally distributed surface particulate matter sampling network (SPARTAN) between January 2013 and April 2019 were analyzed for particulate mass and trace metals content. Metal concentrations exhibited pronounced spatial variation, primarily driven by anthropogenic activities. PM_2.5 levels of lead, arsenic, chromium, and zinc were significantly enriched at some locations by factors of 100–3000 compared …

Divorce, Academic Performance, And Attachment Styles In College Students, Pavllo Neco

Honors Theses

For years, social scientists have pondered the impacts of a parental divorce on the students’ academic performance, as well as their attachment style (Fomby, 2010). In the current study, it is hypothesized that students who experience a parental divorce will perform lower on academic performance and higher on the insecure attachment styles than students whose parents are still intact or remarried. Participants were 73 college students, ages ranging in age from 18-29. More than half of the study consisted of student’s ages 18-19 years. 65% of students who participated were female, and an overwhelming majority of participants were white, with …

Market Viability Of An Avoided Wildfire Ghg Emission Accounting Framework For California, Justine Bui

Master's Projects and Capstones

Forests in California and elsewhere are under an increasing threat of uncharacteristically large and severe wildfires. Fuel treatments, such as tree density reduction or prescribed burns, can alter wildfire behavior and potentially reduce risk. An environmental consulting group is currently developing a probability-based greenhouse gas (GHG) emissions accounting framework that would provide tools to quantify GHG benefits of fuel treatments and help fund said treatments through carbon offset credits. This framework is being developed in collaboration with key stakeholders (such as public agencies, carbon offset registries, non-profit organizations, and the private sector) in the western United States. A market assessment …

Nature And Origin Of The East Traverse Mountains Mega-Landslide, Northern Utah (Usa), Rodney Ryan Chadburn

Theses and Dissertations

The East Traverse Mountains are an E-W trending mountain range dividing Utah and Salt Lake valleys in northern Utah. Geologically perplexing, the nature of the East Traverse Mountains has been under investigation for 140 years. Previously, the mountain range was proposed to be a dismembered but still coherent down-faulted block that experienced 4 km of post-thrusting extension within the Charleston-Nebo thrust sheet. However, new insight on the origin of the East Traverse Mountains indicate that it is a mega landslide, roughly ~100 km3 in size, which catastrophically slid from the upper reaches of the Little-Cottonwood stock to its present-day location. …

Editorial: Advances And Challenges In Ocean Wave Energy Harvesting, Y Liu, B Ding, B Zhou, P Cong, S Zheng

School of Engineering, Computing and Mathematics

Wave energy resource is abundant and huge due to the vast oceanic area on the planet. On the other hand, exploitation of wave energy has never reached a satisfactory level that can replace to a large extent the traditional fossil fuel. The main disadvantage of wave power is the significantly random variability in several timescales: from wave to wave, with sea state, and from month to month (Falcão, 2010). This poses many super challenges to effectively and efficiently extract power from the sea waves. The present collection of research articles reflects the most recent contributions coming forward on harvesting wave …
