Spatially Resolved Stellar Kinematics Of The Ultra-Diffuse Galaxy Dragonfly 44. Ii. Constraints On Fuzzy Dark Matter, Asher Wasserman, Pieter Van Dokkum, Aaron Romanowsky, Jean Brodie, Shany Danieli, Duncan Forbes, Roberto Abraham, Christopher Martin, Matt Matuszewski, Alexa Villaume, John Tamanas, Stefano Profumo

Faculty Publications

Given the absence of directly detected dark matter (DM) as weakly interacting massive particles, there is strong interest in the possibility that DM is an ultralight scalar field, here denoted as "fuzzy" DM. Ultra-diffuse galaxies, with the sizes of giant galaxies and the luminosities of dwarf galaxies, have a wide range of DM halo masses, thus providing new opportunities for exploring the connections between galaxies and their DM halos. Following up on new integral field unit spectroscopic observations and dynamics modeling of the DM-dominated ultra-diffuse galaxy Dragonfly 44 in the outskirts of the Coma Cluster, we present models of fuzzy …

Dark Matter And No Dark Matter: On The Halo Mass Of Ngc 1052, Duncan Forbes, Adebusola Alabi, Jean Brodie, Aaron Romanowsky

Faculty Publications

The NGC 1052 group, and in particular the discovery of two ultra-diffuse galaxies with very low internal velocity dispersions, has been the subject of much attention recently. Here we present radial velocities for a sample of 77 globular clusters associated with NGC 1052 obtained on the Keck telescope. Their mean velocity and velocity dispersion are consistent with that of the host galaxy. Using a simple tracer mass estimator, we infer the enclosed dynamical mass and dark matter fraction of NGC 1052. Extrapolating our measurements with a Navarro–Frenk–White (NFW) mass profile we infer a total halo mass of 6.2(±0.2) × 1012 …

The Energetic Cost Of Anthropogenic Disturbance On The Southern Sea Otter (Enhydra Lutris Nereis), Heather Elizabeth Barrett

Master's Theses

With increased human populations and tourism in coastal areas, there is greater potential for disturbance of marine wildlife. Having high metabolic rates, sea otters (Enhydra lutris nereis) are at risk of increased energetic costs due to disturbance. To investigate these effects, sea otter activity in response to potential disturbance stimuli was recorded over three years, at three California locations: Monterey, Moss Landing, and Morro Bay. A hidden Markov Model was developed to examine how activity varies as a function of location, group size, pup to adult ratio, kelp canopy, and occurrence of and proximity to disturbance stimuli. Results were combined …

Effect Of Nicotine Exposure On Fatigue Mechanics Of Murine Arteries, Elizabeth Ho

Master's Theses

Nicotine is an addictive substance found in electronic cigarettes (e-cigarettes) and cigarettes, and the use of such products has growing concern because of the prevalent use by young adults. Nicotine exposure degrades arterial tissue and results in increased arterial stiffness, which is linked to cardiovascular events, such as stroke and myocardial infarction. The hypothesis of this research is that fatigue loading reveals changes to the mechanical behavior of nicotine-treated arteries that is more informatively discriminating than stiffness alone. Ten murine arteries, five untreated and five nicotine-treated, were subjected to cyclic fatigue loading in an open-circumferential configuration by a custom tensometer …

Determination Of Demagnetizing Factors In Nanomagnets By First-Order Reversal Curves And Ferromagnetic Resonance, Karl Scott Muster

Master's Theses

Magnetic reversal in nickel nanowire arrays due to an axial, external magnetic field was studied through first-order reversal curve (FORC) measurement. A general function modeling the observed Preisach distribution was developed using the moving Preisach model. Fitting allowed determination of the sample's demagnetizing field at saturation and modeling magnetic reversal with respect to the internal magnetic field. Magnetization dynamics in the sample were studied through ferromagnetic resonance (FMR) measurement to aid in interpreting FORC fit results. Combining FORC and FMR results yielded the saturation magnetization and effective demagnetizing factors of the sample. Similar analysis was performed for a thin film …

Monotonic Testing Of Steel Anchor Straps For Alternative Installation Methods In Wood Frame Shear Walls, Randall Block

Master's Theses

Metal wood-connection hardware straps are sometimes installed in ways not intended by the manufacturers; in particular, a shear-wall anchor strap which was manufactured to be used in straight alignment to connect a post above a particular floor of a building to a post below that floor may instead be bent and wrapped around a floor beam. Four specimens using steel straps were constructed and tested in order to simulate building situations. The experimental specimens had wooden posts and engineered-wood floor beams, connected by straps, arranged so that the load paths passed through the straps being tested; the control specimens had …

Preserving Ideals Of Chemical Reaction Networks, Mark Curiel

Master's Theses

Under the assumption of mass-action kinetics, every chemical reaction network has an associated polynomial dynamical system. Rather than study the dynamics of this system, we shall study the ideal generated by the polynomials in the system called the steady state ideal. In this thesis, we will show that there is a combinatorial way to determine the existence of monomials in the steady state ideal using the underlying structure of the network. This allows us to prove that there is a combinatorial condition that is enough to guarantee the steady state ideal is monomial. We introduce three operations on chemical reaction …

Signal Integrity Optimization Of Rf/Microwave Transmission Lines In Multilayer Pcbs, Justin Thien Le

Master's Theses

While allowing for flexible trace routing and device miniaturization, multilayer printed circuit boards (PCB) suffer from performance issues at high frequency due to the impedance mismatch caused by vertical transitions. In this paper, a process for optimizing the high-speed performance of microstrip to stripline transitions in multilayer PCBs is demonstrated. This includes strategic tuning of via dimensions using time-domain reflectometry and an analysis of the use of shielding vias to prevent parasitic cavity resonance. Simulations of optimized 2-layer, 4-layer, and 6-layer microstrip to stripline transitions show a return loss of 20 dB up to 7 GHz. To demonstrate a useful …

Development Of A Computational Elbow Joint Model To Analyze The Effects Of Synovial Fluid On Articular Cartilage During Joint Motion, Abhishek Yellapragada

The model was developed with anatomically accurate 3D bone geometries; articular cartilage geometries that were derived from the 3D bone geometries; ligaments defined as linear springs; muscles embedded as joint non-linear stiffness; and a fluid domain that encompassed the joint articulations with a homogenous, incompressible, …

Students Of Black Or African American Ancestry In Grades 10th -12th Perceptions Of Their Schooling Experiences, Annette Renee Kennedy

Dissertations

California continues to tackle blatant racist acts within school systems across the state as recent headlines read, “Deeply offensive blackface video of California high school student sparks backlash” (Yancey-Bragg, Guynn, & Rhor, 2019, n.p.) and “Four teachers and their principal placed on leave after cheerfully posing for photo with noose” (Lunning, 2019, n.p.). Gaining a greater awareness of the non-headlining actions that take place on a day-to-day basis that have an equally powerful adverse effect on the school experiences of black learners was the focus of this study. Microaggressions are “subtle, stunning, often automatic, and non-verbal exchanges which are put …

Diet‐Induced Obesity Decreases Rate‐Dependent Depression In The Hoffmann’S Reflex In Adult Mice, Gerard Nguyen, Shea Putnam, Mulatwa Haile, Zahra Raza, Martina Bremer, Katherine Wilkinson

Faculty Publications, Biological Sciences

Obesity is associated with balance and motor control deficits. We have recently shown that Group Ia muscle spindle afferents, the sensory arm of the muscle stretch reflex, are less responsive in mice fed a high-fat diet. Here we test the hypothesis that reflex excitability to sensory information from Group Ia muscle spindle afferents is altered in a mouse model of diet-induced obesity. We measured the anesthetized Hoffmann’s or H-reflex, the electrical analog of the muscle stretch reflex. Adult mice of both sexes were fed a control diet (CD; 10% kcal from fat) or a high-fat diet (HFD; 60% kcal from …

The Intensification Of Hurricane Maria 2017 In The Antilles, Mark Jury, Sen Chiao, Raphael Cécé

Faculty Publications, Meteorology and Climate Science

Environmental influences on Hurricane Maria in the Antilles Islands are analyzed at the large-scale (1–25 September) and at the meso-scale (17–20 September 2017). The storm intensified rapidly prior to landfall in Dominica, going from category 1 to 5 in 15 h. As the storm progressed toward Puerto Rico (PR), its NE flank entrained air from seas cooled by the earlier passage of two hurricanes, and strengthened on its SW flank. Operational model forecasts tended to delay intensification until west of the Antilles Islands, thus motivating two independent weather research and forecasting (WRF) simulations. These gave minimal track errors at 1- …
