Optimal Control Of Nonlinear, Nonautonomous, Energy Harvesting Systems Applied To Point Absorber Wave Energy Converters, Houssein Yassin, Tania Demonte Gonzalez, Kevin Nelson, Gordon Parker, Wayne Weaver

Michigan Tech Publications

Pursuing sustainable energy solutions has prompted researchers to focus on optimizing energy extraction from renewable sources. Control laws that optimize energy extraction require accurate modeling, often resulting in time-varying, nonlinear differential equations. An energy-maximizing optimal control law is derived for time-varying, nonlinear, second-order, energy harvesting systems. We demonstrate that sustaining periodic motion under this control law when subjected to periodic disturbances necessitates identifying appropriate initial conditions, inducing the system to follow a limit cycle. The general optimal solution is applied to two point absorber wave energy converter models: a linear model where the analytical derivation of initial conditions suffices and …

ANK3 encodes ankyrin-G, a protein involved in neuronal development and signaling. Alternative splicing gives rise to three ankyrin-G isoforms comprising different domains with distinct expression patterns. Mono- or biallelic ANK3 variants are associated with non-specific syndromic intellectual disability in 14 individuals (seven with monoallelic and seven with biallelic variants). In this study, we describe the clinical features of 13 additional individuals and review the data on a total of 27 individuals (16 individuals with monoallelic and 11 with biallelic ANK3 variants) and demonstrate that the phenotype for biallelic variants is more severe. The phenotypic features include language delay (92%), autism …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Sacrococcygeal teratoma (SCT) is a rare congenital tumour. The risk of malignancy and recurrence are not well defined. Previous studies are small and report differing conclusions about the timing of surgery and the duration of follow-up. We studied the risk of malignant transformation and SCT recurrence after surgery to address these gaps.

METHODS: This was a global retrospective cohort study. Data of consecutive SCT patients was obtained from 145 institutes in 62 countries. Malignant transformation, defined as malignancy at initial resection, malignant recurrence or death due to malignancy, and its risk factors were analysed.

RESULTS: Of the 3612 included …

Manuscripts, Articles, Book Chapters and Other Papers

SUMMARY: Technologies that produce spatial single-cell (SC) data have revolutionized the study of tissue microstructures and promise to advance personalized treatment of cancer by revealing new insights about the tumor microenvironment. Functional data analysis (FDA) is an ideal analytic framework for connecting cell spatial relationships to patient outcomes, but can be challenging to implement. To address this need, we present mxfda, an R package for end-to-end analysis of SC spatial data using FDA. mxfda implements a suite of methods to facilitate spatial analysis of SC imaging data using FDA techniques.

AVAILABILITY AND IMPLEMENTATION: The mxfda R package is freely available …

Threshold Changes In Winter Temperature And Precipitation Drive Threshold Responses Across Nine Global Climate Zones And Associated Biomes, Alexandra R. Contosta, Kyle A. Arndt, Helen M. Baulch, Nora J. Casson, Adrian Harpold, Toni Lyn Morelli, Alexej P.K. Sirén

Faculty Publications

Globally, winter temperatures are rising, and snowpack is shrinking or disappearing entirely. Despite previous research and published literature reviews, it remains unknown whether biomes across the globe will cross important thresholds in winter temperature and precipitation that will lead to significant ecological changes. Here, we combine the widely used Köppen–Geiger climate classification system with worst-case-scenario projected changes in global monthly temperature and precipitation to illustrate how multiple climatic zones across Earth may experience shifting winter conditions by the end of this century. We then examine how these shifts may affect ecosystems within corresponding biomes. Our analysis demonstrates potential widespread losses …

BACKGROUND: Almost half of the US adult population has obesity, which predisposes to atherosclerosis and can lead to poor prognosis in coronary artery disease (CAD). We aim to identify CAD and obesity-related mortality trends among adults in the United States stratified by age, sex, race and geographical location.

METHODS: The CDC-WONDER database was used to extract death certificate data for adults aged ≥ 25 years. Crude mortality rates (CMR) and age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and temporal trends were described by calculating annual percent change (APC) and the average APC (AAPC) in the rates using Joinpoint …

An Empirical Analysis Of The Mmpi-3 Suicidal/Death Ideation Scale, Brittany Barnes Rhodes

Theses and Dissertations

Suicide is a significant concern in society and is one of the leading causes of death in the United States and around the world. Suicidality is particularly prevalent in outpatient psychological treatment centers, with some studies estimating a tenfold increase in prevalence in this setting compared to the population at large. Several measures have been developed to assess suicide risk potential based on symptom frequency and combinations of risk factors, and broadband personality measures have also incorporated suicidality scales into their tests. The current study was focused on assessing the effectiveness of the Suicidal/Death Ideation (SUI) scale on the third …

Enterococcus Faecium: Evolution, Adaptation, Pathogenesis And Emerging Therapeutics, Yahan Wei, Dennise Palacios Araya, Kelli L. Palmer

School of Podiatric Medicine Publications

The opportunistic pathogen Enterococcus faecium colonizes humans and a wide range of animals, endures numerous stresses, resists antibiotic treatment and stubbornly persists in clinical environments. The widespread application of antibiotics in hospitals and agriculture has contributed to the emergence of vancomycin-resistant E. faecium, which causes many hospital-acquired infections. In this Review, we explore recent discoveries about the evolutionary history, the environmental adaptation and the colonization and dissemination mechanisms of E. faecium and vancomycin-resistant E. faecium. These studies provide critical insights necessary for developing novel preventive and therapeutic approaches against vancomycin-resistant E. faecium and also reveal the intricate interrelationships …

Center for Medical Ethics and Health Policy Staff Publications

Neurofibromatosis type 1 (NF1), Noonan syndrome, and related syndromes, grouped as RASopathies, result from dysregulation of the RAS-MAPK pathway and demonstrate varied multisystemic clinical phenotypes. Together, RASopathies are among the more prevalent genetic cancer predisposition syndromes and require nuanced clinical management. When compared with the general population, children with RASopathies are at significantly increased risk of benign and malignant neoplasms. In the past decade, clinical trials have shown that targeted therapies can improve outcomes for low-grade and benign neoplastic lesions but have their own challenges, highlighting the multidisciplinary care needed for such individuals, specifically those with NF1. This perspective, which …

Fatherhood, Family Law, And The Crisis Of Boys And Men, June Carbone, Clare Huntington

Faculty Scholarship

Boys and men in all racial and ethnic groups and across most socioeconomic groups are struggling on many fronts, including education, employment, physical and mental health, and social integration. In these areas and more, boys and men are much worse off than they were only a few decades ago. The crisis — which is concentrated among men without college degrees — is rooted in large-scale structural changes to the economy that have decimated jobs for this group and policy choices that emphasize incarceration while doing little to address economic inequality.

The decline in male well-being is not just a problem …

PURPOSE: Epigenetic dysregulation has been associated with many inherited disorders. RBBP5 (HGNC:9888) encodes a core member of the protein complex that methylates histone 3 lysine-4 and has not been implicated in human disease.

METHODS: We identify 5 unrelated individuals with de novo heterozygous variants in RBBP5. Three nonsense/frameshift and 2 missense variants were identified in probands with neurodevelopmental symptoms, including global developmental delay, intellectual disability, microcephaly, and short stature. Here, we investigate the pathogenicity of the variants through protein structural analysis and transgenic Drosophila models.

RESULTS: Both missense p.(T232I) and p.(E296D) variants affect evolutionarily conserved amino acids located at the …

Trade-Offs In A Reef-Building Coral After Six Years Of Thermal Acclimation, Anna Roik, Marlene Wall, Melina Dobelmann, Samuel Nietzer, Anna Fiesinger, Miriam Reverter, David Brefeld, Peter J Schupp, Matthew Jackson, Marie Rutsch, Julia Strahl

School of Biological and Marine Sciences

There is growing evidence that reef-building corals can acclimate to novel and challenging thermal conditions. However, potential trade-offs that accompany acclimation remain largely unexplored. We investigated physiological trade-offs in colonies of a globally abundant coral species (Pocillopora acuta) that were acclimated ex situ to an elevated temperature of 31 °C (i.e., 1 °C above their bleaching threshold) for six years. By comparing them to conspecifics maintained at a cooler temperature, we found that the energy storage of corals was prioritized over skeletal growth at the elevated temperature. This was associated with the formation of higher density skeletons, lower calcification rates …

2020-Current year OA Pubs

Differences in amyloid positron emission tomography (PET) radiotracer pharmacokinetics and binding properties lead to discrepancies in amyloid-β uptake estimates. Harmonization of tracer-specific biases is crucial for optimal performance of downstream tasks. Here, we investigated the efficacy of ComBat, a data-driven harmonization model, for reducing tracer-specific biases in regional amyloid PET measurements from [

Multiple Negative Impacts Of Marine Plastic Pollution On Tropical Coastal Ecosystem Services, And Human Health And Well-Being, Carya Maharja, Radisti A. Praptiwi, Sainal Sainal, Prawesti Wulandari, Matthew Ashley, Kayleigh Wyles, Joyashree Roy, I Gede Hendrawan, Susan Jobling, Melanie Austen

School of Psychology

There is limited empirical evidence showing the impacts of marine plastic pollution on ecosystem services or on human health and well-being in Global South countries. We aimed to estimate these impacts in the tropical archipelago of Indonesia, one of the top emitters of marine plastics globally, through an iterative Delphi survey, with an expert panel (n = 42) consisting of equal numbers of Indonesian scientists, policymakers, and practitioners. After two rounds of the survey, the analysis of interquartile ranges indicated that the experts reached a consensus in their predictions. The experts agreed that, over the next 10 years, plastics would …

Learning Problems Related To Stochastic Differential Equations, Jinpu Zhou

LSU Doctoral Dissertations

Stochastic differential equations (SDEs) are essential for modeling systems influenced by both deterministic dynamics and random fluctuations, with applications in a wide variety of disciplines. This thesis develops a Bayesian framework for nonparametric learning in SDEs, addressing key challenges in inference, particularly when dealing with complex systems and incomplete data. The thesis begins by establishing a theoretical foundation in optimization over Hilbert spaces, including a generalized representer theorem to address infinite-dimensional optimization problems encountered in nonparametric inference. Building on this, we introduce a Bayesian framework with shrinkage priors to learn drift functions from high-frequency data. Bayesian approach incorporates low-cost sparse …

Precision Bottlebrush Polymers: Synthesis, Characterization, And Structure-Property Relationship, Nduka D. Ogbonna

LSU Doctoral Dissertations

Bottlebrush polymers, a type of non-linear polymer characterized by densely grafted side chains on a linear backbone, offer a versatile platform for material design due to their unique thermomechanical and rheological behavior. Addressing the grand challenge of achieving structural precision for bottlebrush polymers remains crucial because traditional disperse mixtures are plagued with batch variability, limiting our ability to control their functions, and correlate theoretical predictions with experiments. To date, narrow-dispersity bottlebrush polymers remain highly heterogeneous, as they are typically synthesized from disperse linear building blocks.

To address this longstanding challenge of structural heterogeneity in brush polymers, the primary objective of …

Comparison Of Soil Organic Matter Fractions In Non-Grazed And Prescribed Sheep-Grazed Managed Land In Southwest Michigan, Julia M. Shreve, Katelyn Smith, Lauren Burns

Student Summer Scholars Manuscripts

The impact of prescribed sheep grazing on soil organic carbon (SOC) was investigated by comparing a 2-acre grazed and a 2-acre non-grazed (control) portion of redeveloped land previously seeded with pasture mix in Southwest Michigan. This study aimed to measure changes in SOC resulting from prescribed sheep grazing by examining two key soil organic matter (SOM) fractions: particulate organic matter (POM) and mineral-associated organic matter (MAOM) along with soil physical and chemical properties (e.g., bulk density, infiltration rate, moisture content, pH, conductivity). Soil cores were collected from 5 locations within each of the 2-acre plots using a diagonal random sampling …

Research outputs 2022 to 2026

Improving social and emotional well-being (SEWB) among Indigenous adolescents is crucial. Since neurodevelopmental disorders (NDDs) are common in Indigenous people and adverse childhood experiences (ACEs) are important contributors to negative health outcomes throughout the lifespan, we investigated whether limited ACE exposure is associated with reduced risk of NDDs in Australian Indigenous teens using the data from multiple waves (Wave 1 to Wave 9, and Wave 11) of the Longitudinal Study of Indigenous Children (LSIC). We also examined the role of other protective factors, such as Indigenous cultural identity and school connectedness, against NDDs. A strengths-based approach using mixed-effects logistic regression …

Pollination By Birds, Non-Flying Mammals, And European Honeybees In A Heathland Shrub, Banksia Catoglypta (Proteaceae), Stanislaw K. Wawrzyczek, Robert A. Davis, Siegfried L. Krauss, Susan E. Hoebee, Louis M. Ashton, Ryan D. Phillips

Research outputs 2022 to 2026

Vertebrate pollination has evolved in many plant lineages, with pollination by birds the most prevalent strategy. However, in Banksia (Proteaceae) many species are visited by a combination of nectarivorous birds, non-flying mammals (NFMs), and insects, though the relative importance of these pollen vectors for reproduction remains poorly understood. Here, we investigate the contribution to fruit set of birds, NFMs, and insects in Banksia catoglypta—a heathland shrub from south-west Australia. This species flowers in winter and produces large, golden-yellow inflorescences that are typically presented near the ground and consist of rigid, strongly scented flowers with a long stigma-nectary distance—suggesting pollination by …

Pkc-Mediated Phosphorylation Governs The Stability And Function Of Celf1 As A Driver Of Emt In Breast Epithelial Cells, Shebna Massey, Natee Kongchan, Yang Gao, Arindam Chaudhury, Emuejevoke Olokpa, Jason Karch, Anna Malovannaya, Chonghui Cheng, Xiang Zhang, Joel R Neilson

Faculty, Staff and Students Publications

Epithelial to mesenchymal transition (EMT) is believed to be a principal factor contributing to cancer metastasis. The post-transcriptional and post-translational mechanisms underlying EMT are comparatively underexplored. We previously demonstrated that the CELF1 RNA binding protein is necessary and sufficient to drive the EMT of breast epithelial cells, and that the relative protein expression of CELF1 in this context was dictated at the post-translational level. Here, we elucidate the mechanism of this regulation. Mass spectrometric analysis of CELF1 isolated from mesenchymal MCF-10A cells identified multiple sites of serine and threonine phosphorylation on the protein, correlating with the increased stability of this …

A Cross-Systems Primer For Synthetic Microbial Communities, Elijah C Mehlferber, Gontran Arnault, Bishnu Joshi, Laila P Partida-Martinez, Kathryn A Patras, Marie Simonin, Britt Koskella

Faculty, Staff and Students Publications

The design and use of synthetic communities, or SynComs, is one of the most promising strategies for disentangling the complex interactions within microbial communities, and between these communities and their hosts. Compared to natural communities, these simplified consortia provide the opportunity to study ecological interactions at tractable scales, as well as facilitating reproducibility and fostering interdisciplinary science. However, the effective implementation of the SynCom approach requires several important considerations regarding the development and application of these model systems. There are also emerging ethical considerations when both designing and deploying SynComs in clinical, agricultural or environmental settings. Here we outline current …

BACKGROUND: Professional guidelines recommend HCC screening in at-risk patients using semi-annual ultrasound with or without alpha-fetoprotein (AFP); however, this strategy has limited effectiveness due to low adherence and sensitivity. Increasing data support the potential role of blood-based biomarker panels, which could improve both aspects. The biomarker panel GALAD, comprised of sex, age, and 3 blood biomarkers (AFP, AFP-L3, and des-carboxy prothrombin des-carboxy prothrombin), has shown high sensitivity and specificity in biomarker phase II (case-control) and phase III (retrospective cohort) validation studies. However, prospective validation in a large phase IV biomarker clinical utility trial is necessary before its adoption in practice. …
