Harmonic Mean Operator Based Madm-Strategy Under Svpn-Set Environment, Bimal Shil, Suman Das, Rakhal Das, Binod Chandra Tripathy
Neutrosophic Sets and Systems
By using single-valued pentapartitioned neutrosophic set (briefly SVPN-set), one can express uncertainty events having incomplete, indeterminate, and erroneous information in practical applications. This study's primary goal is to present a multi-attribute decision-making (briefly MADM) algorithm that operates in the SVPN-set environment using the notion of single-valued pentapartitioned neutrosophic harmonic mean (briefly SVPNHM) operator and single-valued pentapartitioned neutrosophic weighted harmonic mean (briefly SVPNWHM) operator. Further, we provide a numerical illustration here like, “Location Selection for Installation of Outdoor Air Purifier” to validate the effectiveness and rationality of the proposed MADM algorithm.

Neutrosophic Sets and Systems
Ethics is a discipline that has broken the limits of its field of study, which is related to having the right behavior towards other people, but also to respect nature and life. This has been extended to the accounting and organizational management of companies. This paper proposes a sentiment analysis method based on the NeutroGroup obtained from offuninorms defined by the combining functions in Prospector. The advantage of the proposed method is that in addition to "like" and "dislike", we obtain a result of indeterminacy that can be due either to neutrality or to a contradiction in the short informal …

Analyzing Interdisciplinary Education In General Medicine Using Smarandache's Multivalued Logic Hypothesis Theory And Plithogenic Probability, Dolores Hernandez De La Cantera, Rosangela Caicedo Quiroz, Mairim Lago Queija, Jeanntte Rodriguez Gonzalez, Maikel Y. Leyva Vazquez
Neutrosophic Sets and Systems
Smarandache extended the concept of falsifiability to include hypotheses that involve multiple values. Smarandache's extension of classical logic introduces Partial Falsifiability within multi-valued logic, which allows for the inclusion of partial truth values, uncertainties, and false values, unlike traditional falsifiability which only classifies hypotheses as completely true or false. Using this approach this study investigates specifically the concept of interdisciplinarity in the field of integral general medicine, with a specific emphasis on the integration of nursing procedures. The method employs sentiment analysis of scientific questions using the Consensus tool and plithogenic statistics to assess complex hypotheses. The findings indicate that …

Periodic Information Leakage Fault Detection On A Risc-V Microprocessor, Idris Somoye
Periodic Information Leakage Fault Detection On A Risc-V Microprocessor, Idris Somoye
Electrical and Computer Engineering ETDs
The execution behavior of a Microprocessor (μP) in the presence of a fault is difficult to predict because of the complex interactions across pipeline stages and between functional units within the architecture. Fault effects are known to not introduce any type of anomaly in the input-output behavior for 10s of thousands to millions of clock cycles. These characteristics increase the difficulty of evaluating μP architectures for resilience to information leakage events, i.e., scenarios where a fault causes sensitive data such as an encryption key to be inadvertently diverted to a primary output channel. This dissertation explores two promising strategies for …

Visualization Of Species Tree Likelihood Under The Multispecies Coalescent Model, Jaimasan Sutton
Visualization Of Species Tree Likelihood Under The Multispecies Coalescent Model, Jaimasan Sutton
Mathematics & Statistics ETDs
A commonly used tool for evolutionary biologists is a phylogenetic tree that represents the ancestry of a set of species and the evolution of traits. Statistical models can be used to predict the probabilities of gene trees which represent ancestral relationships of genes sampled from species. Because of this, we are able to represent the likelihood of a species tree, which represents the evolutionary history of a set of species, as a function of the counts of gene tree topologies, where each gene tree represents the ancestry of a specific genetic locus for multiple species. Because we can represent these …

Repeated glacial cycles of the Pleistocene initiated complex sequences of divergence and secondary contact with gene flow for many North American species. In my first chapter, I expand our understanding of the phylogeography of the montane shrew, Sorex monticola, with range-wide genetic sampling and geospatial analyses to reconstruct the history of clades within this species and test whether evolutionarily divergent clades occupy distinct abiotic niches. In my second chapter, I build upon these hypotheses, providing the first estimates of evolutionary relationships and timing of diversification based on genome-wide markers. In my third chapter, I use a systematic review of the …
Validating Reward And Relief Drinking Phenotypes: A Multimethod Assessment, Victoria R. Votaw
Validating Reward And Relief Drinking Phenotypes: A Multimethod Assessment, Victoria R. Votaw
Psychology ETDs
Recent work has examined the extent to which individuals seek alcohol to enhance positive experiences (reward drinking) or relieve aversive states (relief drinking). Although reward/relief drinking subgroups moderate response to two medications for alcohol use disorder (AUD), naltrexone and acamprosate, limitations of reward/relief drinking measures could hinder efforts to translate findings to clinical practice. This dissertation project aimed to validate a brief, practical measure of reward/relief drinking, the Reward and Relief Inventory of Drinking Situations (RR-IDS). Among 426 participants with AUD enrolled in a clinical trial of naltrexone and acamprosate (Study 1), we identified RR-IDS items free of bias across …
Substance Use Patterns Among Muslim American Young Adults: A Mixed Methods Design Assessing Risk And Protective Factors, Donia Hijaz

Muslim Americans are underrepresented in the addictions literature. This mixed methods study sought to examine the frequency of substance use, and identify risk/protective factors of at-risk substance use. Young adults (N = 289; Mage = 22.68, SD = 3.42; 50.9% male) from around the U.S. who identified as Muslim American or from a Muslim background completed a survey. Given that several measures had not been validated with Muslim American samples, open-ended questions were included at the end of those measures. Findings revealed low rates of lifetime substance use in the current sample, preventing any quantitative analyses surrounding risk …
Adaptive Immune Profiling Of Sin Nombre Hantavirus And Severe Acute Respiratory Syndrome Coronavirus 2 Infection, Tonilynn M. Baranowski
Adaptive Immune Profiling Of Sin Nombre Hantavirus And Severe Acute Respiratory Syndrome Coronavirus 2 Infection, Tonilynn M. Baranowski
Biomedical Sciences ETDs
Hantaviruses are causative agents of potentially fatal respiratory illness and/or organ failure in humans worldwide. In the United States, the predominant hantavirus species, Sin Nombre hantavirus (SNV), causes a severe disease pathology, called hantavirus cardiopulmonary syndrome (HCPS). Infection with SNV and subsequent clinical manifestations of HCPS lends itself to case fatality rates approaching 40%, even under supportive care. This is partially due to the lack of FDA-approved vaccines and antivirals, in addition to a deficit in our knowledge regarding the human immune response to SNV. Further investigation of the adaptive immune response may reveal key targets to mediate disease outcome. …
Thermal Oxidative Degradation Of Polystyrene Plastics Used For Food Packaging During Incomplete Waste Incineration, Maycee Hurd
Thermal Oxidative Degradation Of Polystyrene Plastics Used For Food Packaging During Incomplete Waste Incineration, Maycee Hurd
Civil Engineering ETDs
We identified the physical and chemical degradation of polystyrene (PS) plastic used for food packaging after thermal oxidative weathering. Open waste incineration is a widely used waste management practice in isolated and underserved communities. However, the generation of partially incinerated plastics and microplastics (MPs) from this practice is overlooked. Near surface XPS C 1s high resolution analyses show an increase in the intensity of peaks greater than 285 eV corresponding to C/O bonds after burning of PS. Bulk analyses using ATR-FTIR show that thermal oxidation decreased the alkene (3040-3000 cm-1) and alkane (3000-2850 cm-1) C-H stretch signals suggesting PS chain …

Tuning Of Real-Time Optimization Of Heliostat Concentrated Solar Power, Zachary L. Bernius
Mechanical Engineering ETDs
This paper investigates a real-time optimization algorithm for autonomously calibrating the heliostats in a concentrated solar power plant with the goal of maximizing power generation. The current state-of-the-art uses human operators to provide feedback for the heliostats. We use real-time/online measurements to produce an autonomous closed-loop system that does not require human intervention. The paper investigates tuning the gain of the real-time optimization algorithm to quickly and robustly converge to the optimal alignment and stabilize the system. The exponential stability of the system is certified using a quadratic Lyapunov function and static output feedback methods to couple the Lyapunov functions …
