Astronomy: Faculty Publications

Observations of 12CO J = 1 - 0 and HCN J = 1 - 0 emission from NGC 5194 (M51) made with the 50 m Large Millimeter Telescope and the SEQUOIA focal plane array are presented. Using the HCN-to-CO ratio, we examine the dense gas mass fraction over a range of environmental conditions within the galaxy. Within the disk, the dense gas mass fraction varies along the spiral arms but the average value over all spiral arms is comparable to the mean value of interarm regions. We suggest that the near-constant dense gas mass fraction throughout the disk arises from …

Alma Discovery Of A Disk Around The Planetary-Mass Companion Sr 12 C, Ya Lin Wu, Brendan P. Bowler, Patrick D. Sheehan, Laird M. Close, Joshua A. Eisner, William M.J. Best, Kimberly Ward-Duong, Zhaohuan Zhu, Adam L. Kraus

Astronomy: Faculty Publications

We report an Atacama Large Millimeter/submillimeter Array 0.88 mm (Band 7) continuum detection of the accretion disk around SR 12 c, an ∼11 M Jup planetary-mass companion (PMC) orbiting its host binary at 980 au. This is the first submillimeter detection of a circumplanetary disk around a wide PMC. The disk has a flux density of 127 ± 14 μJy and is not resolved by the ∼0.″1 beam, so the dust disk radius is likely less than 5 au and can be much smaller if the dust continuum is optically thick. If, however, the dust emission is optically thin, then …

Polarizations Of Powers Of Graded Maximal Ideals, Ayah Almousa, Gunnar Fløystad, Henning Lohne

Mathematics Faculty Publications

We give a complete combinatorial characterization of all possible polarizations of powers of the graded maximal ideal (x₁,x₂,…,x_m)ⁿ of a polynomial ring in m variables. We also give a combinatorial description of the Alexander duals of such polarizations. In the three variable case m=3 and also in the power two case n=2 the descriptions are easily visualized and we show that every polarization defines a (shellable) simplicial ball. We give conjectures relating to topological properties and to algebraic geometry, in particular that any polarization of an Artinian monomial ideal defines a simplicial ball.

Waiting Room, Hannah White

Master’s Theses and Projects

The short stories and essays in this hybrid creative collection, Waiting Room, aim to add to critical conversations in both creative nonfiction and fiction about identity in relation to physical places and the body. In this collection, I particularly explore how notions of “home” shape one’s identity: grief, mental/physical illness, displacement from home, and other topics pertaining to the body and physicality.

An Efficient End-To-End Deep Neural Network For Interstitial Lung Disease Recognition And Classification, Masum Shah Junayed, Afsana Ahsan Jeny, Md Baharul Islam, Ikhtiar Ahmed, Afm Shahen Shah

Turkish Journal of Electrical Engineering and Computer Sciences

The automated Interstitial Lung Diseases (ILDs) classification technique is essential for assisting clinicians during the diagnosis process. Detecting and classifying ILDs patterns is a challenging problem. This paper introduces an end-to-end deep convolution neural network (CNN) for classifying ILDs patterns. The proposed model comprises four convolutional layers with different kernel sizes and Rectified Linear Unit (ReLU) activation function, followed by batch normalization and max-pooling with a size equal to the final feature map size well as four dense layers. We used the ADAM optimizer to minimize categorical cross-entropy. A dataset consisting of 21328 image patches of 128 CT scans with …

The Impact Of Hurricanes On The Acoustic Detection Of Cetaceans, Aditi Tripathy

Master's Theses and Capstones

Passive acoustic monitoring (PAM) is valuable for understanding the presence, behavior, distribution, and population density of marine mammals. While long-term variability of ambient sound is typically evaluated, the impact of short-term variability due to episodic events has not been assessed until now. Hurricanes Dorian (Category 5; 2019), Florence (Category 4; 2018), and Humberto (Category 3; 2019) impacted the soundscape as observed from the passive acoustic data at the Atlantic Deepwater Ecosystem Observatory Network (ADEON) locations in the US Mid- and South Atlantic Outer Continental Shelf. Hurricanes are increasingly prevalent in the North Atlantic and increase the ambient sound level at …

Black Carbon Dominated Dust In Recent Radiative Forcing On Rocky Mountain Snowpacks, Kelly E. Gleason, Joseph R. Mcconnell, Monica M. Arienzo, Graham Sexstone, Stefan Rahimi

Environmental Science and Management Faculty Publications and Presentations

The vast majority of surface water resources in the semi-arid western United States start as winter snowpack. Solar radiation is a primary driver of snowmelt, making snowpack water resources especially sensitive to even small increases in concentrations of light absorbing particles such as mineral dust and combustion-related black carbon (BC). Here we show, using fresh snow measurements and snowpack modeling at 51 widely distributed sites in the Rocky Mountain region, that BC dominated impurity-driven radiative forcing in 2018. BC contributed three times more radiative forcing on average than dust, and up to 17 times more at individual locations. Evaluation of …

Linking Bad Credentials To Safety Issues, Andrew Martin, Jeeyen Koo, Valerie Keathley-Helil, Mallory Brown, Jennifer Walton

Kentucky Transportation Center Research Report

This study assesses (1) the effectiveness of the Kentucky Automated Truck Screening (KATS) system, (2) the relationship between credential and vehicle safety violations, (3) the relationship between credential and driver safety violations, and (4) the relationship between credential violations and crashes. The KATS system, which is installed at weigh stations throughout the Commonwealth of Kentucky, is highly effective at detecting KYU, IFTA, and UCR violations with sensitivities of 80.54, 87.56, and 88.28 percent, respectively. However, the system is less effective at detecting IRP violations (sensitivity = 20.83 percent). There is a statistically significant relationship between credentialing and vehicle safety violations, …

The "Law To Use The Mark The Delpaís," Act 195-2016: Case Study Of A Puerto Rican Certification Mark With Potential Of Becoming A Geographic Indication For Economic Development, Paola Gabriela Zaragoza Cardenales

Maurer Theses and Dissertations

In 2016, the Puerto Rican Congress codified the “Law for the use of the DelPaís Mark” (the DelPaís Law), creating a composite certification mark called Productos DelPaís de Puerto Rico (the DelPaís Mark) for raw fruits, milk, honey, meats, egg, fish, ornamental plants, spices, vegetables, starches, and value-added products. The Puerto Rican Department of Agriculture intended the DelPaís Mark to function as a certification mark and Geographical Indication (GI) to differentiate local from imported products to promote purchasing of locally produced items and eventually export internationally. A GI is a source identifier identifying that a place makes a particular product …

Faculty Publications

In the context of rapid urbanization, public open spaces in dense urban areas are critical built environment elements to support active lifestyles. Several reviews have explored the associations of public open space attributes with physically active and sedentary behavior. However, few reviews have included studies from Asia, and no studies have focused on dense urban areas. This systematic review analyzed 18 observational studies investigating associations between public open space attributes with physical activity and sedentary behavior in dense urban areas of East Asian countries, including Japan, Taiwan, China, and Hong Kong. We found that closer distance to and a greater …

The Counterflow Dynamics Of Two Correlated Impurities In A Double Well Coupled To A One-Dimensional Bosonic Medium Is Explored. We Determine The Ground-State Phase Diagram Of The System According To The Impurity-Medium Entanglement And The Impurities' Two-Body Correlations. Specifically, Bound Impurity Structures Reminiscent Of Bipolarons For Strong Attractive Couplings As Well As Configurations With Two Clustered Or Separated Impurities In The Repulsive Case Are Identified. The Interval Of Existence Of These Phases Depends Strongly On The Impurity-Impurity Interactions And External Confinement Of The Medium. Accordingly The Impurities' Dynamical Response, Triggered By Suddenly Ramping Down The Central Potential Barrier, Is Affected …

A Physical Model Of Deadmans Run, Quinn Brandt

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

A physical model of Deadmans Run and a pair of railroad bridges was constructed to assess the impacts of the bridges on flood flows. Lower Platte South Natural Resources District is planning a series of improvements to Deadmans Run to improve flood conveyance capacity and remove approximately 500 homes and businesses from the floodplain. The rail bridges are located less than a mile from the confluence of Deadmans Run and Salt Creek, meaning the bridges present a significant bottleneck to the planned improvements. The physical model was used to characterize the drag effects caused by the bridges, which was used …

Comparative Analyses Of De Novo Transcriptome Assembly Pipelines For Diploid Wheat, Natasha Pavlovikj

School of Computing: Dissertations, Theses, and Student Research

Gene expression and transcriptome analysis are currently one of the main focuses of research for a great number of scientists. However, the assembly of raw sequence data to obtain a draft transcriptome of an organism is a complex multi-stage process usually composed of pre-processing, assembling, and post-processing. Each of these stages includes multiple steps such as data cleaning, error correction and assembly validation. Different combinations of steps, as well as different computational methods for the same step, generate transcriptome assemblies with different accuracy. Thus, using a combination that generates more accurate assemblies is crucial for any novel biological discoveries. Implementing …

Applying Mci-062, A Novel Pan-Ras Inhibitor, To Treat Kras-Mutant Lung Cancer, Richard Fu

Honors Theses

RAS is a prevalent oncogene that is mutated in 27% of human cancers. Gain-of-function RAS mutations activate multiple downstream pathways, including the RAS-RAF-MEK-ERK and PI3K/AKT/mTOR pathways, which are critical in tumorigenesis and cancer cell proliferation. RAS proteins such as KRAS, a member of the RAS protein family, and their downstream effectors are attractive targets for cancer therapy since their mutations act as frequent drivers in lung, colorectal, and pancreatic cancers. However, RAS proteins have relatively smooth surfaces that lack traditional binding pockets, making inhibitors specific to RAS difficult to create. Recently, a novel small molecule pan-RAS inhibitor named MCI-062 was …

It begins with overviews of background and planning, recruitment, testing and exercise program protocol, quality control measures, and other relevant organizational issues. A summary of findings is then provided on cardiorespiratory fitness, exercise hemodynamics, insulin and glucose metabolism, lipid and lipoprotein profiles, adiposity and …

Rheological Behavior Of Dspc-, Dbpc-, And Dppc-Oxygen Microbubbles And Their Effectiveness In Improving Survival In A Rat Model Of Lipopolysaccharide-Induced Acute Respiratory Distress Syndrome, Riaz Ur Rehman Mohammed

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Acute respiratory distress syndrome (ARDS) causes 75,000 deaths in the U.S., annually. It is characterized by hypoxemia and damage to the lung alveoli. ARDS Management strategies involve extracorporeal membrane oxygenation (ECMO) and mechanical ventilation, but none of these methods improve the mortality rates. Oxygen microbubbles (OMBs) consist of a lipid shell with an oxygen core and have potential to augment oxygenation to manage ARDS. Previous studies demonstrated significant improvements in systemic oxygenation and mortality upon administering OMBs.

We replicated an ARDS rat model by intratracheal administration of lipopolysaccharide at a 24 mg/kg dose. After inducing the disease in rats, the …

Immigration In Regard To Economic Labor And Reform, Will Ross, Maryella Mccown, Dylan Stone

Immigration Scholarship: History, Trends and Development in Global Immigration

In the last two presidencies, the United States economy has gone through much development regarding immigration and labor. Many key factors of growth in the economy can be identified pertaining to immigration, such as job fulfillment, innovations, and more productivity. Immigrants arrive in the United States with impressive skills that are needed for many occupations. They also run many of their own businesses and provide food and hospitality services for everyone. A common question that many US citizens wonder is “How do immigrants advantage the United States economy?” By bringing in new skills and ideas that had not been discovered …

Increasing Nutrition And Healthy Eating Among Preschoolers, Veronica Trinidad

Capstone Projects and Master's Theses

There is a lack of nutrition education in preschool curriculum. Children are not being taught about the importance of consuming healthier foods. When children are taught about nutrition, they will be able to choose positive eating habits and less chance of having health complications. To address the lack of nutrition education for preschoolers, I will conduct a three-day lesson to increase the awareness of nutrition for preschool children at Teddy Bear Preschool in Monterey, California.

You Matter: Finding School Based Support For Children Dealing With Mental Health Challenges, Melissa Machuca

A Grammar Sketch Of Kinamayo, Benjamin James Schmitt

Theses and Dissertations

Kinamayo (Kamayo) is an Austronesian language spoken on the eastern part of the island of Mindanao, Philippines. This thesis presents a grammar sketch of the case system, a preliminary analysis of the voice system, reference phrase structure, and verb tense, modality, and aspect. The theoretical framework used for this analysis is Role and Reference Grammar. Within this framework, Kamayo is best analyzed as a symmetrical voice language in addition to having an antipassive voice. The case system of active and stative verbs observed in Kamayo supports this analysis. Reference phrases are marked by case, which helps identify syntactic arguments and …

Real Memories For False Events: An Examination Of Individual Characteristics That Predict Flashbulb Memories For Real And Fictitious Mass Shootings, Richard Belz

Theses and Dissertations

Multiple studies have examined flashbulb memories (FBM) for various events, but few studies have evaluated these memories within the context of mass shootings. The current investigation examined adult participants’ FBMs for both real and fictitious mass shootings collected in an online survey of 607 participants in the United States. ANOVA, Chi-Square, and regression analyses were used to analyze survey data to examine participant characteristics associated with FBMs for these events. More than 40% of participants had one or more FBMs for real mass shootings. Of note, more than 20% of participants had one or more FBMs for shootings that never …
