membership demographics. A hope offering Black people a racial paradise 2. Providing favorable coverage and representation among the Black community. Facilitated by the increasing importance and demand of semiconductors for the smartphoneand even the automobile industry, thermal atomic layer deposition ALD has gained tremendous industrial interest as it offers a way to efficiently deposit thin-films with ultra-high conformity.
It is ucla phd thesis largely due to its superior ability to deliver ultra-conformal dielectric thin-films with high aspect-ratio surface structures, which are encountered more and more often in the novel design of metal-oxide-semiconductor field-effect transistors MOSFETs in the NAND Not-And -type flash memory devices, ucla phd thesis.
Based on the traditional thermal ALD method, the plasma enhanced atomic layer deposition PEALD allows for lower operating temperature and speeds up the deposition process with the involvement of plasma species. Despite the popularity of these two methods, the development of their operation policies remains a complicated and expensive task, which ucla phd thesis the construction of an accurate and comprehensive simulation model.
A series of studies have been carried out ucla phd thesis elucidate the mechanisms and the conceptof the PEALD process. In particular, process characterization focuses on the development of a first-principles-based three-dimensional, multiscale computational fluid dynamics CFD model, together with reactor geometry optimizations, of SiO2 thinfilm thermal atomic layer deposition ALD using bis tertiary-butylamino silane BTBAS and ozone as precursors.
Also, a comprehensive multiscale computational fluid dynamics CFD model incorporating the plasma generation chamber is used in the deposition of HfO2 thin-films utilizing tetrakis dimethylamido hafnium TDMAHf and O2 plasma as precursors. Despite the great deal of research effort, ALD and PEALD processes have not been fullycharacterized from the view point of process control.
This study aims to use previously developed multiscale CFD simulation model to design and evaluate an optimized control scheme to deal with industrially-relevant disturbances.
Specifically, ucla phd thesis, an integrated control scheme using a proportional-integral PI controller and a run-to-run R2R controller is proposed and evaluated to ensure the deposition of high-quality conformal thin-films. The ALD and PEALD processes under typical disturbances are ucla phd thesis using the multiscale CFD model, and the integrated controllers are applied in the process domain. Using the controller parameters determined from the open-loop results, ucla phd thesis, the developed integrated PI-R2R controller successfully mitigates the disturbances in the reactor with the combined effort of both controllers.
It takes the main character Paidion through different time periods to confront the sources of her fears ucla phd thesis her parents, and ultimately makes her contemplate on her upbringing. It is also centered around the dual natures on human-beings and the world around us.
This dissertation consists of a focused study of the low melting point liquid metal known commercially as Galinstan. This metal is notable for being readily liquid at room temperature, being non-toxic, and forming a peculiar oxide layer that is confined to the surface of the liquid, ucla phd thesis. This study consists of four parts. The first is a literature review of the field of flexible and stretchable electronics. The purpose of this review is to assess the state of the field and to make the case for the value of Galinstan as a primary conducting element in the manufacture of these devices.
With this case made, the remaining three parts can be sorted into two overarching concepts: experiments designed to produce data relevant to the drop on demand printing of flexible electronics, and to the study of fundamental fluid mechanics phenomenon, often overlapping throughout, ucla phd thesis. The first study involves the use of tensiometry to measure the effective surface tension, as well as explore the wetting behavior of the liquid metal on glass.
For measuring the surface tension, ucla phd thesis, we developed a ucla phd thesis technique that combines principles of both the Wilhelmy plate method, but with a rod modification, ucla phd thesis, with the Du No�y ring method. After measuring the surface tension, we studied the wetting behavior of the metal, namely the dynamic contact angle and found the advancing contact angle θ??
Next, we performed droplet impact experiments of liquid metal on glass substrate. Utilizing the wetting information from the tensiometry experiments, we were able to develop a novel model for impact driven spreading of liquid metal on glass for Weber numbers ranging from 10 to This model shows new scaling behavior as compared to other droplet impact models and we compare and contrast these models of impact.
This model is also predictive and would serve to modulate voxel size in additive manufacturing operations with Galinstan. The final set of experiments were of partially coalescing liquid metal droplets in 1 M NaOH, ucla phd thesis.
These droplets were observed to bounce on the liquid metal interface and reach different heights as they coalesced into smaller and smaller droplets. We developed a first order model based on the Stokes approximation for droplets in a viscous fluid which we refined with a improved numerical model which was more valid for the range of Reynolds numbers tested.
This dissertation studies the efficient and fair allocation of indivisible goods without monetary transfer. It is a collection of three papers and uses school-choice programs as a motivating example. I provide theoretical results that can guide the design of new allocation systems as well as tools that can be used to enhance existing systems. In Chapter 1, I analyze how information ucla phd thesis affects social welfare using a stylized model.
In my model, the utility of agents consists of a vertical "quality" component and a horizontal "idiosyncratic taste" component, ucla phd thesis. The exact qualities of the objects are unknown to the agents, and the social planner seeks an information-disclosure policy that will maximize the total utility.
The results show that 1 the optimal disclosure policy hides small differences in quality and reveals large differences in quality, 2 more information is disclosed when the valuations of the quality are heterogeneous, and 3 the Immediate Acceptance mechanism is more conducive for information disclosure than the Deferred Acceptance mechanism.
In Chapter 2, I study the collocation of groups of students in school-choice programs. In particular, I examine when and how stochastic assignment matrices can be decomposed into lotteries over deterministic ucla phd thesis subject to collocation constraints. I first show thatregardless of the number of pairs of twins in the student bodytwin collocation can be maintained in a decomposition if one extra seat can be added to each school.
I then propose a decomposition algorithm based on Column Generation that can incorporate a wide variety of constraints including collocation constraints. In Chapter 3, I propose a new notion of fairness that combines the concept of rank values and the maximin principle, ucla phd thesis. An assignment is rank-egalitarian undominated REU if there is no other assignment that is equally or more egalitarian for any set of rank values.
I ucla phd thesis that each REU assignment can be generated as a solution to a linear programming problem that maximizes the weighted sum of expected rank values of the worst-off agents. I also provide an algorithm that generates special subsets of REU assignments that are practically important. There are tremendous health and financial burdens attributed to cardiovascular disease.
The most ucla phd thesis type, known as ischemic heart disease, is due to plaque buildup within the coronary arteries that supply the myocardium with oxygen and nutrients. Reduction or blockage of blood flow can lead to irreversible loss of cardiomyocytes, the main building blocks of the heart, with estimates placing that loss to upward of a billion cells.
Despite medical therapy, the majority of patients ucla phd thesis progress to heart failure, in which the main challenge for the development of therapeutic strategies is the limited regenerative ability of the adult mammalian heart. Our dissertation takes a multi-faceted approach in understanding cardiac regeneration and exploring whether neonatal systemic factors could be the gateway to a new therapy for ischemic heart disease. We report the development of a multi-colored mouse reporter system that enables deeper understanding of the cellular mechanisms ucla phd thesis early cardiac tissue formation.
We apply a bioengineering approach to develop biodegradable and biocompatible nanoparticles as a new tool for clonal expansion analysis of cardiac cells. We hope that our body of work pushes forward the field of cardiac regeneration and sets the stage for the development of therapeutic interventions to prevent the progression to heart failure after an acute myocardial infarction. Across a number of politically relevant domains, ucla phd thesis, Latinx immigrants and their co-ethnics hold progressive attitudes and preferences relative to Anglo whites despite countervailing pressure to assimilate to Anglo political standards.
This dissertation includes three papers that explain the puzzle of relative political progressivism among Latinxs by highlighting the role of an increasingly threatening interior immigration enforcement context after the implementation of Clinton-era immigration restrictions.
I theorize a generalized sense of illegality is motivated by 1 the increasing societal integration of undocumented immigrants, 2 an increasingly restrictive immigration enforcement context, and 3 the development of an ethnicized illegality attached to Latinx ethnic group members. I then demonstrate a sense of illegality maintains Latinx progressivism despite countervailing conservative forces.
Chapter 1 ucla phd thesis perceptibly threatening immigration enforcement contexts undercut well-established patterns of attitudinal convergence with Anglo whites on immigration policy preferences.
Chapter 2 forwards a Dynamic Theory of Threat Solution Ownership to explain how the threat of deportation motivates support for Democratic candidates among Latinxs and partisan defection among Republican Latinxs specifically. Chapter 3 offers a theoretical framework to understand how the threat of deportation may motivate pro-Black political attitudes among non-Black Latinxs despite the perceptible lack of commonality in exposure to immigration enforcement, ucla phd thesis.
The urban region's seismic resilience is being actively studied in recent years as a measure for risk mitigation, where the identification of seismically vulnerable buildings and the assessment of their performance play indispensable roles.
However, ucla phd thesis, it is a labor-intensive and computationally expensive task to evaluate tens of thousands of buildings in a region because the identification requires professional judgment at a site and the seismic assessment demands comprehensive modeling depending on structure-specific data. Nevertheless, it is feasible with the aid of advanced development of the Internet of Things IoT and computer technology. In this study, a data-driven framework including two pipelines that focus on soft-story buildings and non-ductile reinforced concrete frames is proposed.
The first pipeline focuses on identifying soft-story buildings in the city of Santa Monica California through 3D point clouds and convolutional neural networks CNNs.
Although prior studies showed promising results in detecting soft-story buildings based on well-selected street-view images, false predictions are common when it is applied to real-world data. To address this issue, the pipeline implements point-cloud data where spatial information is available to segment building points and extract density features for training deep learning models and identifying soft-story buildings. The transfer learning TL technique is adopted to avoid overfitting in deep neural networks, and the parameters within the pipeline are investigated for optimal performance.
The results illustrate the potential applicability of the pipeline for developing pre-and post-event countermeasures. The second pipeline focuses on another seismically vulnerable building, namely, the non-ductile reinforced concrete building NDRCB. Prior studies indicated around 1, NDRCBs in Los Angeles that are urgently waiting for detailed assessment and mandatory retrofit or demolition if necessary.
Because the fulfillment of these ordinances will last for decades, ucla phd thesis, the potential risk of major losses will persist. To this end, an automatic method that harvests building information from IoT and imagery data generates ucla phd thesis models, conducts probabilistic seismic assessment, ucla phd thesis, and estimates the losses for NDRCB frames is hence developed.
The accuracy of the data harvesting module using deep CNNs is validated with the existing inventory data. The archetypal frames are developed based on the era-specific representative code and are validated through nonlinear static ucla phd thesis nonlinear dynamic analyses of previously investigated NDRCBs. State-of-the-practice loss estimation methodologies including HAZUS and FEMA P are adopted in the pipeline for constructing damage fragility functions and corresponding losses.
The regional application focuses on intensity-based assessment for thousands of individual buildings instead of a scenario-based assessment.
This research demonstrates how advanced data mining techniques and data-driven approaches can aid to solve civil engineering problems. While the framework currently focuses on soft-story ucla phd thesis non-ductile frame buildings, it is expected to be extended in-depth and breadth in the future. That is, more detailed models and other seismically vulnerable infrastructures can be included.
Gray matter GM atrophy is considered one of the best predictors of disability accumulation in multiple sclerosis MS yet the mechanisms underlying its progression are poorly understood. Currently, there are no directly neuroprotective therapies in MS that can halt the progression of Ucla phd thesis atrophy. While GM atrophy has been established in the most commonly used mouse model for MS, experimental autoimmune encephalomyelitis EAEucla phd thesis, there is a lack of studies directly investigating associated pathologies of GM atrophy and methods of sparing GM volume.
The projects in this dissertation were designed with the goal of characterizing changes in GM volume and associated pathology. This was an important step in establishing the use of magnetic resonance imaging MRI and voxel-based morphometry VBM to identify differences in GM volume.
Moreover, ucla phd thesis highlighted the importance of performing experimental analyses within sex as we determined that differences exist in the brain in healthy mice. In the third chapter, I sought to utilize VBM to localize atrophy ucla phd thesis vivo in a chronic mouse model of EAE and to identify the spatial relationship between downstream axonal damage in the spinal cord and gray matter loss. I found substantial GM volume loss throughout the brain particularly within the cortex, caudoputamen, and thalamus during EAE.
Further, I found axonal damage in the spinal cord was negatively correlated to GM volume in motor and sensorimotor regions of the cerebral cortex, ucla phd thesis. In the fourth chapter, I describe a network of pathology associated with GM atrophy that is disrupted by estriol treatment. I further identified ligation of ERbeta as method of inducing remyelination in GM.
Lastly, in chapter five, I used VBM to identify sex differences in GM atrophy during EAE. Using voxel-wise regression analysis I found a sex-specific relationship between disability and GM atrophy in the somatosensory cortex in males.
I further found evidence of increased neuronal loss and increased axonal transection in males with EAE compared to their healthy controls than females with EAE compared to their healthy controls. Localizing atrophy and related pathology will allow for us to investigate the molecular underpinnings of GM volume loss and potentially lead to the development of better neuroprotective therapies for patients with MS.
Water resources are increasingly being impacted by chemicals of emerging concern like per- and polyfluoroalkyl substances PFASs and nitrotriazolone NTO.
