description: There is overwhelming evidence that the Milky Way has formed its stars at a rel- atively constant rate throughout the Hubble time. This implies that its stock of cold gas was not in place since the beginning but it has been acquired slowly through gas accretion. The gas accretion must have been at low metallicity in order to reconcile the metallicities observed in the disc with the predictions of chemical evolution models. But how does this gas accretion take place? I review the current evidence of gas accretion into the Milky Way and similar galaxies through the infall of cold gas clouds and satellites. The conclusion from these studies is that the infalling gas at high column densities observed in HI emission is a least one order of magnitude below the value required to sustain star formation, thus accretion must come from a different channel. The likely reservoir for gas accretion is the cosmological corona of virial-temperature gas in which every galaxy must be embedded. At the interface between the disc and the corona the cold high-metallicity disc gas and the hot coronal medium must mix efficiently and this mix- ing causes the cooling and accretion of the lower corona. I show how this mechanism reproduces the kinematics of the neutral extraplanar gas in the Milky Way and other nearby galaxies and the ionised high-velocity clouds observed in HST spectra. I conclude with the speculation that the loss in efficiency of the disc-corona interaction is the ultimate cause for the evolution of disc galaxies towards the red sequence.

title: The Effects of a Dedicated Education Unit on Nurse Retention and Turnover
Creators: name: Campbell, Cherilyn
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: Despite the fast growth of healthcare jobs in the United States, there is a deficit in the nursing workforce. Literature has shown high nurse turnover within the first year as a new graduate nurse. Healthcare organizations will need to explore innovative ways to impact nursing retention and turnover to keep up with the growing demand. The purpose of this Doctor of Nursing Practice (DNP) project is to perform and evaluate a comprehensive review to determine the effect of a dedicated education unit (DEU) on nurse retention and turnover within an academic-practice partnership. Literature has shown the benefits of the DEU on nursing education and clinicals within schools of nursing but there is a gap regarding the benefit of the DEU for the academic practice partner. This DNP project will begin to show the benefits of the DEU prepared new graduate nurse on retention at the academic practice partnership organization and can be utilized as a starting point for more in depth and comprehensive concurrent reviews.

description: We investigate the BCS-BEC crossover in an ultracold atomic gas in the presence of disorder. The disorder is incorporated in the mean-field formalism through Gaussian fluctuations. We observe evolution to an asymmetric line-shape of fidelity susceptibility as a function of interaction coupling with increasing disorder strength which may point to an impending quantum phase transition. The asymmetric line-shape is further analyzed using the statistical tools of skewness and kurtosis. We extend our analysis to density of states (DOS) for a better understanding of the crossover in the disordered environment.

description: Deep reinforcement learning has achieved superhuman racing performance in high-fidelity simulators like Gran Turismo 7 (GT7). It typically utilizes global features that require instrumentation external to a car, such as precise localization of agents and opponents, limiting real-world applicability. To address this limitation, we introduce a vision-based autonomous racing agent that relies solely on ego-centric camera views and onboard sensor data, eliminating the need for precise localization during inference. This agent employs an asymmetric actor-critic framework: the actor uses a recurrent neural network with the sensor data local to the car to retain track layouts and opponent positions, while the critic accesses the global features during training. Evaluated in GT7, our agent consistently outperforms GT7's built-drivers. To our knowledge, this work presents the first vision-based autonomous racing agent to demonstrate champion-level performance in competitive racing scenarios.

description: In Fermi superfluids, like superfluid 3He, the viscous normal component can be considered to be stationary with respect to the container. The normal component interacts with the superfluid component via mutual friction which damps the motion of quantized vortex lines and eventually couples the superfluid component to the container. With decreasing temperature and mutual friction the internal dynamics of the superfluid component becomes more important compared to the damping and coupling effects from the normal component. This causes profound changes in superfluid dynamics: the temperature-dependent transition from laminar to turbulent vortex motion and the decoupling from the reference frame of the container at even lower temperatures.

description: Acoustically driven air pockets trapped in artificial crevices on a sur- face can emit bubbles which organize in (interacting) bubble clusters. With increasing driving power Fernandez Rivas et al. [Angew. Chem. Int. Ed., 2010] observed three different behaviors: clusters close to the very pits out of which they had been created, clusters pointing toward each other, and merging clusters. The latter behavior is highly undesired for technological purposes as it is associated with a reduction of the radical production and an enhancement of the erosion of the reactor walls. The dependence on the control parameters such as the distance of the pits and the conditions for cluster-merging are examined. The underlying mechanism, governed by the secondary Bjerknes forces, turns out to be strongly influenced by the nonlinearity of the bubble oscillations and not directly by the number of nucleated bubbles. The Bjerknes forces are found to dampen the bubble oscillations, thus reducing the radical production. Therefore, the increased number of bubbles at high power could be the key to understand the experimental observation that, after a certain power threshold, any further increase of the driving does not improve the sonochemical efficiency.
title: The Influence of Volga Tatar Folk Music and Soviet Cultural Policies on the Orchestral Composers of Kazan
Creators: name: Brown, Jane
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: After a brief historical overview of Volga Tatar history and Soviet political and historical contexts, this document begins with a detailed description of Volga-Tatar folk musical characteristics, including probable influences as described, analyzed, and transcribed by twentieth and twenty-first century Volga Tatar scholars. In this description, the author attempts to give the preferential voice to Tatar perspectives, such as the early ethnographers and Tatar ethnomusicologists from Kazan State Conservatory, the officials from the Union of Composers of the Republic of Tatarstan, and of course, the composers themselves. The author’s detailed discussion of folk music elements and genres is then followed by an elucidation of extramusical influences on the early generations of composers in Kazan, including Soviet era cultural policies, programs, and institutions. Next, is found an overview of the events leading up to the development of professional music in Kazan, followed by brief biographical sketches of a majority of Kazan’s composers who wrote symphonic music—covering their lives, musical accomplishments, stylistic characteristics, major symphonic works, and spheres of influence. Some of the Volga Tatar composers from the earliest generation—those who the author considers to be the forefathers of the Kazan school of composition, include: Sultan Gabyashi, Zagidulla Yarullin, and Salikh Saidashev. Then follows the first generation of professionally-trained Tatar orchestral composers, including: Mansur Muzafarov, Zagid Khabibullin, Nazib Zhiganov, Färid Yarullin, and Rustem Yakin. Next, the author briefly illustrates the lives, compositional styles, and musical contributions of second, third, and most recent generations of Volga Tatar composers, showing evidence of intergenerational influence between the first generations and those who followed. In the final chapter, Ms. Brown shares musical examples drawn from these composers' orchestral scores that illustrate their musical explorations and influences. This musical analysis endeavors to show Tatar folk music influences, as well as evidence of outside influences, including the Soviet Russian school, neighboring ethnic cultures, and Western influences. It also examines their attempts to fuse the attributes and genres of their folk music with the complexities of larger, developmental, symphonic forms and other compositional practices and techniques of Western, Western European, and Soviet Russian Schools. Through this narrative and subsequent analysis, the author's stated objective is to identify the unique characteristics of the Kazan School of composition through examining its orchestral composers and their compositional styles, striving to shed light on the works and lives of the orchestral composers of Kazan, who, until this day, remain largely unknown in the West, in both professional and collegiate orchestral programs.

description: Cashman Field is a minor league sport stadium one-mile north of the world famous “Fremont Street Experience” in Downtown Las Vegas, Nevada. Minor league sports stadiums are microcosms of their communities, and Cashman Field’s history is Las Vegas’s history. Although the city’s first permanent sports venue, the stadium endured numerous cycles of colonialism, stadium building, successful operation, neglect, decay, and abandonment. Now at the end of another cycle, Cashman Field is being forgotten as Las Vegas transitions into a major league sports town. Sports stadiums reveal the social, cultural, and economic factors that define twentieth-century American history, but Cashman Field’s specific site is too important to Las Vegas’s history to be silenced and erased. The locations was a reliable water source for the Southern Paiutes, center of the local Elks club’s city-promoting Helldorado frontier festival, and home to Las Vegas’s first professional sports teams. Oral histories, newspaper articles, and sporting event attendance figures reveal Cashman Field as an essential site of civic engagement, social interaction, and resistance in Las Vegas’s contested outdoor recreation and sporting landscape.

description: Lyrical, but without holding too much to sentimentality, this thesis investigates the Jamaican immigrant experience in America. The linked and expansive essays interrogate why a young woman with everything necessary to do well in Jamaica—class, education, a family legacy—would give it all up to move to America. And why she would return 20 years later when much of what she associates about herself is American-made. Brown juxtaposes the death of her parents, George Floyd, and the death of her American Dream. This series of intertwined narrative arcs suggests some redemption of the American Dream while reminding us that there is no place like home. Brown looks at how her need for belonging drove her pursuit of the American Dream only to realize she had it in Jamaica all along.
title: A Quality Improvement Project to Improve Health Care Provider Self-Efficacy in Rural Primary Pediatric Care Clinics through Training Intervention
Creators: name: Borgsmiller, Alison
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: American Association of Pediatrics recommends screening for various developmental delays in children, but it does not explicitly recommend a tool for screening social and emotional development at well-child checks (WCCs). Therefore, provider self-efficacy (SE) is lacking, and screening rarely occurs. This quality improvement (QI) project sought to improve healthcare provider SE using the Ages and Stages Questionnaire: Social-Emotional, Second Edition (ASQ:SE-2), an evidence-based practice screening tool for identifying such delays in children at 30–60-month WCC visits.At rural healthcare centers in San Luis Obispo, California, participants completed the Self-Efficacy Twelve Questionnaire prior to and 30 days following a training intervention. While the questionnaire assessed a provider’s perceived SE for social and emotional developmental screening in children at WCC visits, the training intervention—handouts and online activitie — reinforced practices to improve provider SE in conducting these evaluations. In comparing pre and posttraining scores, the intervention had a statistically significant effect on provider SE using the ASQ:SE-2 to screen for and identify social and emotional development in 30–60-month-olds, improving patient outcomes with earlier referrals to intervention services. The QI project also determined providers with the most negligible improvement in SE after the training intervention had a baseline preintervention SE score above 100. The limitations of this pilot project were the small sample size, provider difficulty completing the intervention due to the pandemic (i.e., lack of time and patient volume), lack of early intervention service providers, and lack of expedited referrals.

description: Since their inception, mandatory disclosure rules have had at least three rationales. One is to protect investors from making poor investment decisions due to lack of knowledge. A second is to protect the reputations of the markets in which investors buy securities. A third is to promote efficiency through better capital allocation and reduced agency costs of management. These rationales coexisted peacefully for many decades because they differed little in their implications for legal choice. Their peaceful coexistence is coming to an end. Technological and political forces are moving us toward a situation where the share market for a large number of the world's issuers is becoming global. This trend raises the issue of statutory reach: Which country's disclosure regime should apply to which issuers? The different rationales give very different answers to this question.

The need to decide on the best approach to statutory reach is thus an occasion to reexamine the three rationales for mandatory disclosure. The reexamination is revealing. Investor protection, while a worthy goal for many aspects of securities regulation, is a surprisingly weak justification for mandatory disclosure rules. As for market protection, it is hard to argue that in a world of competing markets, any one market will enjoy a net gain in trading volume by having strict disclosure rules that give it a better reputation. The only rationale for mandatory disclosure that really holds up is efficiency.

Identification of efficiency as the paramount rationale for mandatory disclosure suggests a clear principle of statutory reach. Each country should regulate the disclosure behavior of issuers of its nationality and no others. It should not be concerned with where an issuer's shares are traded or what the nationality of the buyers is. This approach assigns to each country regulatory authority over the issuers whose disclosure behavior most affects its welfare. Global welfare will be maximized, because each issuer will be regulated by the country that will benefit most by getting the level of required disclosure right. A switch to the issuer-nationality approach will also prevent a kind of regulatory competition that could lead to suboptimally low disclosure levels required by all countries. For similar reasons, the issuer-nationality approach is also the best approach for the United States in terms of promoting its own welfare. This is so even if other countries do not follow suit.
title: Teaching Medication Reconciliation to Nursing Students Through Live Actor Simulation
Creators: name: Boll, Tamara
Publisher: name: University of Nevada, Las Vegas

description: Medication reconciliation is a significantly important process for safe patient care. It is the process of creating an accurate list of medications that a patient takes. Medication reconciliation is completed when a patient is admitted to a hospital and also when the patient is discharged from the hospital. Medication reconciliation is an important step that is needed to prevent medication discrepancies. However, errors with the medication reconciliation process still occur in the healthcare system. Nurses are most responsible for medication reconciliation. Nursing students lack training and education in reconciling medications. The primary goal of this project was to teach undergraduate nursing students the process of medication reconciliation utilizing a live actor simulation. The aim of the project is to increase undergraduate nursing students' knowledge and confidence levels in completing admission and discharge medication reconciliations. For this project, nursing students were engaged in a live actor simulation which engaged them in an admission and discharge medication reconciliation. The students answered knowledge questions and rated their confidence levels before and after the live actor simulation. Their knowledge levels were assessed through a 10-question multiple-choice test on content related to the medication reconciliation process. A 10-point Likert scale was used to measure their confidence levels with the process. The live actor simulation was proven effective in increasing undergraduate nursing students' knowledge levels and confidence levels.

description: Human-machine interfaces (HMI) facilitate communication between humans and machines, and their importance has increased in modern technology. However, traditional HMIs are often static and do not adapt to individual user preferences or behavior. Adaptive User Interfaces (AUIs) have become increasingly important in providing personalized user experiences. Machine learning techniques have gained traction in User Experience (UX) research to provide smart adaptations that can reduce user cognitive load. This paper presents an ongoing exploration of a method for generating adaptive user interfaces by analyzing user interactions and contextual data. It also provides an illustrative example using Markov chains to predict the next step for users interacting with an app for an industrial mixing machine. Furthermore, the paper conducts an offline evaluation of the approach, focusing on the precision of the recommendations. The study emphasizes the importance of incorporating user interactions and contextual data into the design of adaptive HMIs, while acknowledging the existing challenges and potential benefits.

description: Given a simple connected graph on $N$ vertices with size $|E|$ and degree sequence $d_{1}\leq d_{2}\leq ...\leq d_{N}$, the aim of this paper is to exhibit new upper and lower bounds for the additive degree-Kirchhoff index in closed forms, not containing effective resistances but a few invariants $(N,|E|$ and the degrees $d_{i}$) and applicable in general contexts. In our arguments we follow a dual approach: along with a traditional toolbox of inequalities we also use a relatively newer method in Mathematical Chemistry, based on the majorization and Schur-convex functions. Some theoretical and numerical examples are provided, comparing the bounds obtained here and those previously known in the literature.

description: We present [Fe II] 1.64 μm imaging observations for jets and outflows from young stellar objects (YSOs) over the northern part (~ 24'x45') of the Carina Nebula, a massive star forming region. The observations were performed with IRIS2 of Anglo-Australian Telescope and the seeing was ~1.5"+-0.5". Eleven jet and outflow features are detected at eight different regions, and are named as Ionized Fe Objects (IFOs). One Herbig-Haro object candidate missed in Hubble Space Telescope Hα observations is newly identified as HHc-16, referring our [Fe II] images. IFOs have knotty or longish shapes, and the detection rate of IFOs against previously identified YSOs is 1.4 %, which should be treated as a lower limit. Four IFOs show an anti-correlated peak intensities in [Fe II] and Hα, where the ratio I([Fe II])/I(Hα) is higher for longish IFOs than for knotty IFOs. We estimate the outflow mass loss rate from the [Fe II] flux, using two different methods. The jet-driving objects are identified for three IFOs (IFO-2, -4, and -7), for which we study the relations between the outflow mass loss rate and the YSO physical parameters from the radiative transfer model fitting. The ratios of the outflow mass loss rate over the disk accretion rate are consistent for IFO-4 and -7 with the previously reported values (10^-2-10^+1), while it is higher for IFO-2. This excess may be from the underestimation of the disk accretion rate. The jet-driving objects are likely to be low- or intermediate-mass stars. Other YSO physical parameters, such as luminosity and age, show reasonable relations or trends.

title: The Limits of Critical Rhetoric: Towards a Postcritical Orientation
Creators: name: Bezotte, James
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: In 1989, Raymie McKerrow’s essay “Critical Rhetoric: Theory and Praxis” served as a culmination for a new mode of rhetorical analysis that would reshape the field in the decades following. His essay combined the works of Michel Foucault and other rhetoric scholars such as Michael McGee, Maurice Charland, and Philip Wander to create the method of discourse critique called “critical rhetoric.” Essential to this practice are McKerrow’s equally important and interrelated “critique of domination,” “critique of freedom,” and “permanent criticism.” These components respectively help critics identify where social change should occur within discourses of power, motivate realignments of power for the better, and avoid absolutist determinations of truth. However, the tendency in critical rhetoric’s legacy has been on the critique of domination while the utility of the critique of freedom has been unexplored, thereby limiting the utility and purpose of critical rhetoric. In this thesis, I draw on Rita Felski’s argument that emphasizing the hermeneutics of suspicion is limiting for critique to similarly argue that emphasizing the critique of domination is limiting for critical rhetoric. Felski offers “postcritical reading” as an alternative mode of critique that incorporates affective engagement and aesthetic dimensions. Building from Felski’s and McKerrow’s work, I offer a mode of critique called a “postcritical orientation” motivated by my notion of “permanent conversation,” to explore alternative possibilities for critical rhetoric to enhance human social relations through and beyond critique. My postcritical orientation centers around Foucault’s self-care for others while the permanent conversation engages with the “others of discourse” based on Emmanuel Levinas’ moral philosophies and the stoic egalitarian notion of sermo. To illustrate how my contribution would effect social change by enhancing human social relations, I discuss the works of Tony Adams and Deeyah Khan as respective scholarly and documentary film exemplars of this mode of critical engagement.
Triangular flow of thermal photons from an event-by-event hydrodynamic model for 2.76A TeV Pb+Pb collisions at LHC

description: We calculate the triangular flow parameter $v_3$ of thermal photons from an event-by-event ideal hydrodynamic model for $0--40\%$ central collisions of Pb nuclei at $\sqrt{s_{NN}}$=2.76 TeV at LHC. $v_3$ determined with respect to the participant plane (PP) is found to be non-zero, positive and its $p_T$ dependence is qualitatively similar to the elliptic flow parameter $v_2$(PP) of thermal photons in the range $1 \le p_T \le 6$ GeV/$c$. In the range $p_T \, \le $ 3 GeV/$c$, $v_3$(PP) is found to be about $50--75\%$ of $v_2$(PP) and for $p_T \, >$ 3 GeV/$c$ the two anisotropy parameters become comparable. The local fluctuations in the initial density distribution as well as the initial global geometry of the produced matter in the event-by-event hydrodynamic framework are responsible for this substantial value of $v_3({\rm PP})$. However, as expected, the triangular flow parameter calculated with respect to the reaction plane $v_3$(RP) is found to be close to zero. We show that $v_3$(PP) strongly depends on the value of the fluctuation size scale $σ$ especially in the higher $p_T \, (\ge 3 {\rm GeV}/c)$ region where a larger value of $σ$ results in a smaller $v_3({\rm PP})$. In addition, the $v_3{\rm (PP)}$ is found to increase with the assumed formation time of the thermalized system.

description: This work examines the faunal subsistence practices at Lake Roberts Vista, a small Mimbres pueblo with a pithouse component occupied during the Late Pithouse to Classic Mimbres periods (A.D. 550-1130). It is in the Sapillo Valley, a tributary to the Gila River in southwestern New Mexico. Inhabitants consumed mostly deer and rabbits throughout their occupation. Evidence suggests a decline in Artiodactyla resource abundance in later years based on a declining Artiodactyl Index and an increasing fragmentation rate of Artiodactyla bones. Inhabitants captured more cottontails than jackrabbits throughout their occupation.

description: Bit-flip mutation is a common mutation operator for evolutionary algorithms applied to optimize functions over binary strings. In this paper, we develop results from the theory of landscapes and Krawtchouk polynomials to exactly compute the probability distribution of fitness values of a binary string undergoing uniform bit-flip mutation. We prove that this probability distribution can be expressed as a polynomial in p, the probability of flipping each bit. We analyze these polynomials and provide closed-form expressions for an easy linear problem (Onemax), and an NP-hard problem, MAX-SAT. We also discuss some implications of the results for runtime analysis.

description: Due to dynamic network conditions, routing is the most critical part in WMNs and needs to be optimised. The routing strategies developed for WMNs must be efficient to make it an operationally self configurable network. Thus we need to resort to near shortest path evaluation. This lays down the requirement of some soft computing approaches such that a near shortest path is available in an affordable computing time. This paper proposes a Fuzzy Logic based integrated cost measure in terms of delay, throughput and jitter. Based upon this distance (cost) between two adjacent nodes we evaluate minimal shortest path that updates routing tables. We apply two recent soft computing approaches namely Big Bang Big Crunch (BB-BC) and Biogeography Based Optimization (BBO) approaches to enumerate shortest or near short paths. BB-BC theory is related with the evolution of the universe whereas BBO is inspired by dynamical equilibrium in the number of species on an island. Both the algorithms have low computational time and high convergence speed. Simulation results show that the proposed routing algorithms find the optimal shortest path taking into account three most important parameters of network dynamics. It has been further observed that for the shortest path problem BB-BC outperforms BBO in terms of speed and percent error between the evaluated minimal path and the actual shortest path.

description: It is found that in some metals an intrinsic localized mode may exist with frequency above the top of the phonon spectrum. The necessary condition, requiring sufficiently high ratio of quartic to cubic anharmonicity may be fulfilled because of screening of the interaction between ions by free electrons. Starting from the known literature values of the pair potentials we have found that in Ni and Nb the derived localized mode condition is fulfilled. MD simulations of the nonlinear dynamics of Ni and Nb confirmed that high frequency ILMs may exist in these metals.

description: The signature of free core nutation (FCN) is found in the motion of the celestial intermediate pole in the celestial reference frame and in the resonance behaviour of the frequency-dependent Earth tidal displacement in its diurnal band. We focus on estimation of the FCN parameters, i.e. the period and amplitude. We run several global adjustments of 27 years of very long baseline interferometry (VLBI) data (1984.0 - 2011.0) to determine the FCN period from partial derivatives of the VLBI observables with respect to the FCN as contained in the nutation of the celestial intermediate pole and in the solid Earth tidal displacement in the diurnal band. Finally, we estimate the FCN period by a global adjustment from both phenomena simultaneously, which has not been done before. We find that our estimate of the FCN period of -431.18 +/- 0.10 sidereal days slightly deviates from the conventional value of -431.39 sidereal days. Additionally, we present our empirical model of the FCN with variable amplitude and phase compatible with the estimated period.

title: Improving Nurse Self-Efficacy Regarding Depression among Cardiovascular Disease Patients: An Education Intervention
Creators: name: Beatty, Presten
Publisher: name: University of Nevada, Las Vegas

description: Depression is a principal cause of increased morbidity, mortality, and decreased quality of life for cardiovascular disease patients. Low levels of nurse confidence have been the outcomes of several studies and anecdotal reports regarding providing care for and approaching patients with acute and chronic illnesses in conjunction with behavioral and mental health issues. Current literature suggests that improving nursing education on the prevalence and impacts of depression improves nurse confidence. Depression screening tool education provided to nurses, with detailed disease information, empowers nurses in their attitudes, knowledge, and behaviors regarding patient depression. By improving depression screening rates among cardiovascular disease patient adverse short-term and long-term outcomes can be reduced or evaded. This Doctor of Nursing Project aims to improve nurses’ confidence in patient depression identification/screening. To accomplish this in an inpatient medical unit, nursing staff completed an informal nursing depression education. The training focused on altering attitudes, knowledge, and practices associated to patient depression. The predicted outcomes are an improved self-efficacy after completion of the education. A sample of 23 paired nursing participants analysis revealed an improvement of 11% in total in the completed survey scores after the education intervention. Further development and recognition are needed to close healthcare personnel’s gap in caring for chronic disease patients with comorbid behavioral health problems.
title: Developing Vocal Agility of Light Lyric Coloratura Soprano Voices Through the Neglected Repertoire of French Opéra Comique
Creators: name: Baron, Valentine
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: This document explores light lyric coloratura soprano roles in the French opéra comique genre through an analysis of seven arias and their impact on the development of vocal agility. The opéra comique genre was popular at the beginning of the eighteenth century, but declined to disappear from the stage at the end of the nineteenth century. Despite the opéra comique’s influence on many other vocal genres, the genre is today neglected. Opportunities for singers to improve and practice challenging coloratura in this repertoire are limited. The two most famous arias from the genre which are the Doll Aria and Juliette’s Waltz make the selection of arias in the voice studio repetitive. The disappearance of the genre from the stage took singers away from its large repertoire and limited them on their choice of French operatic arias. This document study poses the following question: How would a revival of neglected French opéra comique arias affect vocal agility practice? The question is answered by presenting a brief history of the opéra comique genre from its creation to its decline. Then, to confer about vocal agility, the author presents a series of exercises from old and modern vocal methods. The purpose is to reconnect singers with the practice of vocal agility and encourage the use of these methods in the repertoire. Finally, seven neglected coloratura arias of the opéra comique genre are analyzed to discuss the synopsis of the opera, character analysis, musical form, and the performance of demanding vocal agility parts. To answer the question at hand, the methodology involved a historical analysis of eighteenth and nineteenth century operatic manuscripts, as well as study of contemporary vocal pedagogy books. Furthermore, vocal pedagogues and musicologists were interviewed throughout the project to offer their insights on the opéra comique genre, the repertoire, and the pedagogy of vocal agility.

description: Target tracking using observations from multiple sensors can achieve better estimation performance than a single sensor. The most famous estimation tool in target tracking is Kalman filter. There are several mathematical approaches to combine the observations of multiple sensors by use of Kalman filter. An important issue in applying a proper approach is computational complexity. In this paper, four data fusion algorithms based on Kalman filter are considered including three centralized and one decentralized methods. Using MATLAB, computational loads of these methods are compared while number of sensors increases. The results show that inverse covariance method has the best computational performance if the number of sensors is above 20. For a smaller number of sensors, other methods, especially group sensors, are more appropriate..

description: We present the first measurement of the absolute proper motions of IRAS 00259+5625 (CB3, LBN594) associated with the HI loop called the "NGC281 superbubble" that extends from the Galactic plane over ~300 pc toward decreasing galactic latitude. The proper motion components measured with VERA are (mu_alpha cos(delta), mu_delta) = (-2.48 +/- 0.32, -2.85 +/- 0.65) mas yr^{-1}, converted into (mu_l cos(b), mu_b) = (-2.72 +/- 0.32, -2.62 +/- 0.65) mas yr^{-1} in the Galactic coordinates. The measured proper motion perpendicular to the Galactic plane (mu_b) shows vertical motion away from the Galactic plane with a significance of about ~4-sigma. As for the source distance, the distance measured with VERA is marginal, 2.4^{+1.0}_{-0.6} kpc. Using the distance, an absolute vertical motion (v_{b}) of -17.9 +/- 12.2 km s^{-1} is determined with ~1.5-sigma significance. The tendency of the large vertical motion is consistent with previous VLBI results for NGC 281 associated with the same superbubble. Thus, our VLBI results indicate the superbubble expansion motion whose origin is believed to be sequential supernova explosions.

title: Dust-Gas Dynamics Driven By the Streaming Instability with Various Pressure Gradients
Creators: name: Baronett, Stanley
Publisher: name: University of Nevada, Las Vegas

description: The radial pressure gradient (RPG), along the midplane of gaseous protoplanetary disks (PPD) – planetary nurseries – poses a severe obstacle to planet formation. Micron-sized dust grains, embedded in the disc, must quickly grow to kilometer-sized planetesimals – the building blocks of planets – before fatally drifting inwards, by RPG-induced gas drag, into a central host star. However, the RPG simultaneously powers one of the most robust processes to overcome this radial-drift barrier: the streaming instability (SI). Spontaneously triggered, the SI aerodynamically concentrates drifting dust via drag-induced, coupled interactions and feedback with the surrounding gas. In particular, the non-linear phase of the SI has not been rigorously or thoroughly studied in the presence of different RPGs, despite implications and expectations from linear analysis. Thus, we numerically simulate and analyse the non-linear evolution of the SI among various RPGs in unstratified, 2D shearing sheets, corotating with the disc, using the Athena++ code, extended to include Lagrangian particles with feedback to the gas. Depending on particle size and initial dust concentration, we find that different RPGs noticeably affect the non-linear growth, saturation, structure, and resultant dust density distributions of the SI, the details of which are not obvious nor expected from linear analysis. Our results offer many new, valuable insights into the complexity of dust-gas dynamics as well as implications for both planet formation theories and PPD observations.

description: We provide a clarification of the description of Langevin diffusions on Riemannian manifolds and of the measure underlying the invariant density. As a result we propose a new position-dependent Metropolis-adjusted Langevin algorithm (MALA) based upon a Langevin diffusion in $\mathbb{R}^d$ which has the required invariant density with respect to Lebesgue measure. We show that our diffusion and the diffusion upon which a previously-proposed position-dependent MALA is based are equivalent in some cases but are distinct in general. A simulation study illustrates the gain in efficiency provided by the new position-dependent MALA.
