Entropic Energy-Time Uncertainty Relation, Patrick J. Coles, Vishal Katariya, Seth Lloyd, Iman Marvian, Mark M. Wilde

Faculty Publications

Energy-time uncertainty plays an important role in quantum foundations and technologies, and it was even discussed by the founders of quantum mechanics. However, standard approaches (e.g., Robertson's uncertainty relation) do not apply to energy-time uncertainty because, in general, there is no Hermitian operator associated with time. Following previous approaches, we quantify time uncertainty by how well one can read off the time from a quantum clock. We then use entropy to quantify the information-theoretic distinguishability of the various time states of the clock. Our main result is an entropic energy-time uncertainty relation for general time-independent Hamiltonians, stated for both the …

Assessing The Relation Between Quality And Sustainability In The Operating Room, Yasaswi Sri Sai Gudipudi

LSU Master's Theses

Maintaining quality at an affordable cost has been a major challenge for many healthcare organizations. Healthcare providers are trying to address this issue while protecting the environment, meeting social responsibilities and contributing to sustainable development of systems. Instead of linking quality with just clinical outcomes, healthcare services are trying to view quality and safety as part of professional ethics or “the right thing to do.” In order to provide a framework for quality assessment in healthcare systems, the Institute of Medicine (IOM) pointed out that the system should have the following six aims: safety, effectiveness, patient-centeredness, timeliness, efficiency, and equity. …

How Did You Code “I'M Really Confident That I Can Find The Exact Ikea Pillow”?: Creating An Effective Codebook As A Team, Andrea Hebert

Faculty Publications

The subject librarian for Louisiana State University’s School of Library & Information Science designed a short survey that included open-ended questions to explore the self-efficacy of graduating MLIS students. The librarian asked a graduating MLIS student to participate in the study as a co-investigator. The survey results were imported into Dedoose, a web-based application, which allowed the co-investigators to collaborate at a distance for qualitative coding and analysis. Although teams of researchers often create the initial codebook collaboratively, the co-investigators in this study each created individual codebooks using inductive coding, which draws themes from data. After the co-investigators completed their …

Modes Of Cartoon Corporeal Performance, Gregory Langner

LSU Doctoral Dissertations

This dissertation project works to introduce and interrogate a phenomenon I am calling cartoon corporeality. The phenomenon refers to the varied ways in which cartoons “escape” their usual two-dimensionality through performance, appearing to manifest in physical environments in ways that should be understood as culturally impactful. Cartoon corporeality encompasses different modes of performance wherein the explicit visual presence of a cartoon subject informs an immediately observable physical impact through the body of the performer. I interrogate the phenomenon by focusing on four select modes of cartoon corporeal performance: videogame play, cosplay, theatrical adaptation, and the active weaving of cartoons …

History, Politics, And Religion In The Life And Compositions Of Sahba Aminikia, Sinella Aghasi Moshabad

LSU Doctoral Dissertations

Sahba Aminikia is an Iranian-American composer who was underrepresented in his home country. He was born into a family with Baha’i faith only two years after the Islamic Revolution of Iran in 1979. The consequences of the revolution brought several challenges for him as a musician and a religious minority. Aminikia was deprived of the right to further his education, so he first moved to Russia, and later on, immigrated to the United States where he received his master's degree in composition. The research is focused on the analysis of the two pieces titled One Day; Tehran(2010), and Shab …

Conservation Adoption Among Owners And Tenantfarmers In The Southern United States, Naveen Adusumilli, Hua Wang

Faculty Publications

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. This study investigates owner and tenant characteristics and differences between these two groups in their participation in federal conservation initiatives. Bivariate probit model analysis, based on a 2016–2017 Louisiana row-crop producer’s survey show that owners, relative to tenant farmers, are more likely to adopt conservation in early years of ownership. The results emphasize the need for mechanisms for tenants in short-term contracts to invest in long-term conservation. Moreover, conservation initiatives should be tailored, as tenant farmers are increasingly farming more land and policies should carefully account for this growing group of …

Robust Resource Allocation With Imperfect Channel Estimation In Noma-Based Heterogeneous Vehicular Networks, Shengjie Guo, Xiangwei Zhou

Faculty Publications

In heterogeneous vehicular networks, non-orthogonal multiple access (NOMA) with effective resource allocation improves spectrum efficiency by allowing multiple users to share the same channel. However, channel estimation errors caused by high mobility in vehicular networks affect system robustness and link reliability. As a result, resource allocation in high-mobility scenarios is a challenging issue. In this paper, robust resource allocation is studied to improve both the throughput performance and reliability of NOMA-based heterogeneous vehicular networks. A cascaded Hungarian channel assignment algorithm is proposed to simplify the formulated resource allocation problem with reliability requirements into a robust power allocation problem with chance …

John Adams Composing Through Others: Modeling, Innovation, And Recomposition, Michael Edward Palmese

LSU Doctoral Dissertations

John Adams has frequently embedded allusions to the music of others in his work while also drawing on more general stylistic conventions and sensibilities of others to inform his creative output. Although this dynamic has been widely acknowledged in Adams’s body of work by scholars and critics generally, it has received little sustained attention or explanation. I argue that much of his work involves “composing through others,” a process in which he adopts, in various ways, the aesthetic conventions, styles, and sensibilities of other composers. By unearthing traces of this creative approach through a focus on short, but significant, periods …

Conductors' Annotated Scores: A Comprehensive Study, Leandro De Magalhaes Gazineo

LSU Doctoral Dissertations

Conductors’ annotations have a different nature and goal from those of orchestral musicians.

The purpose of this study is to obtain a better understanding of the process of conductors’ annotations based on examined scores[1]collected from professional conductors and supported by a questionnaire answered by twenty-seven participants.

Certain questions provided a better understanding of the elements used in conductors’ annotations. For example: Why do some conductors prefer to use symbols, words, numbers, or colors? What kind of annotations are more suitable to specific repertories? Why are reinforcement markings, although redundant, so popular among conductors and why do some conductors …

An Intersectional Analysis Of Black Working-Class Women Becoming Members Of The Academy, Tifanie W. Pulley

LSU Doctoral Dissertations

In a society based on race, gender and class, Black working-class women are some of the most economically marginalized invisible people in American society. However, some of these women have managed to escape economic marginalization and rise to the highest academic levels. Black working-class women becoming members of the academy is a curious phenomenon, given that the traditional American faculty profile is populated largely by white males from middle class backgrounds. Being Black, ­­working-class and female brings together a complex process of identity construction, class-consciousness, and status negotiation. For one, they were not raised in families that have traditional economic, …

When Can Competition And Dispersal Lead To Checkerboard Distributions?, Tad Dallas, Brett A. Melbourne, Alan Hastings

Faculty Publications

© 2018 The Authors. Journal of Animal Ecology © 2018 British Ecological Society Checkerboard distributions—mutually exclusive species co-occurrences—are a common observation in community ecology and biogeography. While the underlying causes of checkerboard distributions have remained elusive, a long-standing argument is that they are representative of strong competitive interactions and/or dispersal limitation. We explore this using a stochastic two-patch metacommunity model combined with an experimental two-patch system of competing Tribolium species, quantifying checkerboard distributions using the abundance-based index A st . We find that maintenance of checkerboard distributions is possible in a limited parameter space consisting of low dispersal rates, low …

Deepdrug3d: Classification Of Ligand-Binding Pockets In Proteins With A Convolutional Neural Network, Michal Brylinski, Limeng Pu, Rajiv Gandhi Govindaraj, Jeffrey Mitchell Lemoine

Faculty Publications

Comprehensive characterization of ligand-binding sites is invaluable to infer molecular functions of hypothetical proteins, trace evolutionary relationships between proteins, engineer enzymes to achieve a desired substrate specificity, and develop drugs with improved selectivity profiles. These research efforts pose significant challenges owing to the fact that similar pockets are commonly observed across different folds, leading to the high degree of promiscuity of ligand-protein interactions at the system-level. On that account, novel algorithms to accurately classify binding sites are needed. Deep learning is attracting a significant attention due to its successful applications in a wide range of disciplines. In this communication, we …

Gobbling Chronology Of Eastern Wild Turkeys In South Carolina, Patrick H. Wightman, John C. Kilgo, Mark Vukovich, Jay R. Cantrell, Charles R. Ruth, Bradley S. Cohen, Michael J. Chamberlain, Bret A. Collier

Faculty Publications

Eastern wild turkeys (Meleagris gallopavo silvestris) use a polygynous-promiscuous mating system, wherein males compete for mating opportunities and communicate with females via courtship behaviors. One courtship behavior is vocalization (gobbling), which attracts females and signals dominance to other males. However, temporal variation in gobbling activity may be influenced by external stimuli, environmental variation, and hunter activity. Gobbling activity is a key determinant of hunter satisfaction, and gobbling chronology is often used by state agencies to inform regulatory processes. To identify factors influencing gobbling activity, we evaluated daily gobbling chronology on 3 sites in South Carolina, USA (Webb Wildlife Management Area …

Prediction Of Ice-Free Conditions For A Perennially Ice-Covered Antarctic Lake, M. K. Obryk, P. T. Doran, J. C. Priscu

Faculty Publications

©2019. American Geophysical Union. All Rights Reserved. Although perennially ice-covered Antarctic lakes have experienced variable ice thicknesses over the past several decades, future ice thickness trends and associated aquatic biological responses under projected global warming remain unknown. Heat stored in the water column in chemically stratified Antarctic lakes that have middepth temperature maxima can significantly influence the ice thickness trends via upward heat flux to the ice/water interface. We modeled the ice thickness of the west lobe of Lake Bonney, Antarctica, based on possible future climate scenarios utilizing a 1D thermodynamic model that accounts for surface radiative fluxes as well …
