Probability Distributions Arising In Connection With The Inspection Paradox For The Poisson Process, James E. Marengo, Anne Marino Himes, David L. Farnsworth, W. Cade Reinberger

Articles

The Inspection Paradox refers to the fact that in a Renewal Process, the length of the interarrival period which contains a fixed time is stochastically larger than the length of a typical interarrival period. To provide a more complete understanding of this phenomenon, conditioning arguments are used to obtain the distributions and moments of the lengths of the interarrival periods other than the one containing this fixed time for the case of the time-homogeneous Poisson Process. Distributions of the waiting times for events that occur both before and after this fixed time are derived. This provides a fairly complete probabilistic …

Modeling And Fitting Two-Way Tables Containing Outliers, David L. Farnsworth

Articles

A model is proposed for two-way tables of measurement data containing outliers. The two independent variables are categorical and error free. Neither missing values nor replication are present. The model consists of the sum of a customary additive part that can be fit using least squares and a part that is composed of outliers. Recommendations are made for methods for identifying cells containing outliers and for fitting the model. A graph of the observations is used to determine the outliers’ locations. For all cells containing an outlier, replacement values are determined simultaneously using a classical missing-data tool. The result is …

Lifestyle Modifications And Nutritional And Therapeutic Interventions In Delaying The Progression Of Chronic Kidney Disease: A Review, Lean Alkhatib, Lorena A. Velez Diaz, Samyukta Varma, Arsh Chowdhary, Prachi Bapat, Hai Pan, Geetika Kukreja, Prasannalaxmi Palabindela, Sri Abirami Selvam, Kartik Kalra

Hematology/Oncology Articles

Chronic kidney disease (CKD) is a debilitating progressive illness that affects more than 10% of the world's population. In this literature review, we discussed the roles of nutritional interventions, lifestyle modifications, hypertension (HTN) and diabetes mellitus (DM) control, and medications in delaying the progression of CKD. Walking, weight loss, low-protein diet (LPD), adherence to the alternate Mediterranean (aMed) diet, and Alternative Healthy Eating Index (AHEI)-2010 slow the progression of CKD. However, smoking and binge alcohol drinking increase the risk of CKD progression. In addition, hyperglycemia, altered lipid metabolism, low-grade inflammation, over-activation of the renin-angiotensin-aldosterone system (RAAS), and overhydration (OH) increase …

Forest Ecosystem Properties Emerge From Interactions Of Structure And Disturbance, J. Christina Mitchell, Daniel M. Kashian, Xiongwen Chen, Stella Cousins, David J. Flaspohler, Daniel S. Gruner, Jeremy S. Johnson, Thilina D. Surasinghe, Jenny Zambrano, Brian Buma

Michigan Tech Publications, Part 1

Forest structural diversity and its spatiotemporal variability are constrained by environmental and biological factors, including species pools, climate, land-use history, and legacies of disturbance regimes. These factors influence forest responses to disturbances and their interactions with structural diversity, potentially creating structurally mediated emergent properties at local to continental spatial scales and over evolutionary time. Here, we present a conceptual framework for exploring the emergent properties that arise from interactions between forest structural diversity and disturbances. We synthesize and present definitions for key terms, including emergent property, disturbance, and resilience, and highlight various types and examples of emergent properties, such as …

Properties And Emissions Of Three-Layer Particleboards Manufactured With Mixtures Of Wood Chips And Partially Liquefied Bark, Wen Jiang, Stergios Adamopoulos, Reza Hosseinpourpia, Thomas Walther, Sergej Medved

Michigan Tech Publications, Part 1

Partial liquefaction of residual biomass shows good potential for developing new materials suitable for making bio-based composites. Three-layer particleboards were produced by replacing virgin wood particles with partially liquefied bark (PLB) in the core or surface layers. PLB was prepared by the acid-catalyzed liquefaction of industrial bark residues in polyhydric alcohol. The chemical and microscopic structure of bark and residues after liquefaction were evaluated by means of Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM), while the particleboards were tested for their mechanical and water-related properties, as well as their emission profiles. Through a partial liquefaction process, some …

A Simple Micromilled Microfluidic Impedance Cytometer With Vertical Parallel Electrodes For Cell Viability Analysis, Jason Eades, Julianne F. Audiffred, Micah Fincher, Jin Woo Choi, Steven A. Soper, William Todd Monroe

Michigan Tech Publications, Part 1

Microfluidic impedance cytometry has been demonstrated as an effective platform for single cell analysis, taking advantage of microfabricated features and dielectric cell sensing methods. In this study, we present a simple microfluidic device to improve the sensitivity, accuracy, and throughput of single suspension cell viability analysis using vertical sidewall electrodes fabricated by a widely accessible negative manufacturing method. A microchannel milled through a 75 µm platinum wire, which was embedded into poly-methyl-methacrylate (PMMA), created a pair of parallel vertical sidewall platinum electrodes. Jurkat cells were interrogated in a custom low-conductivity buffer (1.2 ± 0.04 mS/cm) to reduce current leakage and …

With the successful launch and commissioning of JWST, we can now obtain high-resolution infrared imaging to probe the youngest stellar populations and dust emission on the scales of star clusters and molecular clouds (∼5-50 pc). In Cycle 1, PHANGS is conducting an eight-band imaging survey from 2 to 21 μm of 19 nearby spiral galaxies. Optical integral field spectroscopy, CO(2-1) mapping, and UV-optical imaging for all 19 galaxies have been obtained through large programs …

Pyrolysis Transports, And Transforms, Pfas From Biosolids To Py-Liquid, Patrick J. Mcnamara, Melvin S. Samuel, Sandeep Sathyamoorthy, Lynne Moss, Danny Valtierra, Hugo Cortes Lopez, Nicholas J. Nigro, Stephen Somerville, Zhongzhe Liu

Civil and Environmental Engineering Faculty Research and Publications

Per- and poly-fluoroalkyl substances (PFAS) in wastewater solids have resulted in bans on land application of biosolids, causing utilities to explore thermal treatment options. Pyrolysis is a thermal treatment process that converts wastewater solids to biochar, py-liquid (i.e., aqueous phase liquid and non-aqueous phase liquid), and py-gas. Research on the impact of pyrolysis on PFAS in biosolids has yielded mixed results, and no research has investigated if PFAS are present in the py-liquid. The goals of this research were to determine if pyrolysis releases PFAS with the effluent py-liquid and to distinguish “removal” from “transformation” of PFAS. Triplicate …

Exercise Science Faculty Research and Publications

Background

We undertook a randomized controlled trial (RCT) that investigated the effectiveness of a theory-based, Internet-delivered, behavioral intervention focusing on physical activity promotion for immediate and sustained improvements in secondary, patient-reported outcomes (PROs) of function, symptoms, and quality of life (QOL) in multiple sclerosis (MS).

Method

Persons with MS (N = 318) were recruited from throughout the United States and randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period by persons who were uninvolved in screening, recruitment, random assignment, and outcome assessment. There …

Depression, Anxiety, And Physical Activity In Older Adults With Multiple Sclerosis, Rachel E. Bollaert, C. Danielle Jones, Petra Silic, Robert W. Motl

Exercise Science Faculty Research and Publications

This study examined levels of depression and anxiety symptoms (Hospital Anxiety and Depression Scale scores), and self-reported (Godin Leisure-Time Exercise Questionnaire), and accelerometer-measured physical activity in older adults with multiple sclerosis (n = 40) compared with age- and sex-matched healthy controls (n = 40). We observed differences in depression, anxiety, and physical activity between groups and further observed that minutes/day of moderate to vigorous physical activity partially accounted for group differences in depression scores. We provide preliminary support for research examining approaches for increasing moderate to vigorous physical activity and possibly reducing depression symptoms in older adults with …

Inducible Nitric Oxide Synthase Embedded In Alginate/Polyethyleneimine Hydrogel As A New Platform To Explore No-Driven Modulation Of Biological Function, Shaimaa Maher, Lauren A. Smith, Celine A. El-Khoury, Haitham F. Kalil, Khalid Sossey-Alaoui, Mekki Bayachou

Chemistry Faculty Publications

Nitric oxide (NO), a small free radical molecule, turned out to be pervasive in biology and was shown to have a substantial influence on a range of biological activities, including cell growth and apoptosis. This molecule is involved in signaling and affects a number of physiologic functions. In recent decades, several processes related to cancer, such as angiogenesis, programmed cell death, infiltration, cell cycle progression, and metastasis, have been linked with nitric oxide. In addition, other parallel work showed that NO also has the potential to operate as an anti-cancer agent. As a result, it has gained attention in cancer-related …

The Constitution’S Waning Enforceability: Constitutional Torts After Egbert & Vega, Bailey D. Barnes

UC Law Constitutional Quarterly

The 2021 term of the Supreme Court of the United States produced two opinions significantly dampening the future of constitutional tort actions, which are cases brought to remedy a government agent’s deprivation of an individual’s constitutional rights. First, in Egbert v. Boule, the Court refused to extend Bivens liability to an excessive force claim made against a United States Border Patrol Agent. Second, in Vega v. Tekoh, the Court contravened the traditional understanding of the Fifth Amendment’s Self-Incrimination Clause by preventing a § 1983 civil rights action against a sheriff’s deputy who procured an un-Mirandized statement from a criminal suspect. …

Machine Learning Approximations To Predict Epigenetic Age Acceleration In Stroke Patients, Isabel Fernández-Pérez, Joan Jiménez-Balado, Uxue Lazcano, Eva Giralt-Steinhauer, Lucía Rey Álvarez, Elisa Cuadrado-Godia, Ana Rodríguez-Campello, Adrià Macias-Gómez, Antoni Suárez-Pérez, Anna Revert-Barberá, Isabel Estragués-Gázquez, Carolina Soriano-Tarraga, Jaume Roquer, Angel Ois, Jordi Jiménez-Conde

2020-Current year OA Pubs

Age acceleration (Age-A) is a useful tool that is able to predict a broad range of health outcomes. It is necessary to determine DNA methylation levels to estimate it, and it is known that Age-A is influenced by environmental, lifestyle, and vascular risk factors (VRF). The aim of this study is to estimate the contribution of these easily measurable factors to Age-A in patients with cerebrovascular disease (CVD), using different machine learning (ML) approximations, and try to find a more accessible model able to predict Age-A. We studied a CVD cohort of 952 patients with information about VRF, lifestyle habits, …

2020-Current year OA Pubs

OBJECTIVE: To delineate the full phenotypic spectrum and characterize the natural history of limb girdle muscular dystrophy type D1 (LGMDD1).

METHODS: We extracted age at clinical events of interest contributing to LGMDD1 disease burden via a systematic literature and chart review. Manual muscle testing and quantitative dynamometry data were used to estimate annualized rates of change. We also conducted a cross-sectional observational study using previously validated patient-reported outcome assessments (ACTIVLIM, PROMIS-57) and a new LGMDD1 questionnaire. Some individuals underwent repeat ACTIVLIM and LGMDD1 questionnaire assessments at 1.5 and 2.5 years.

RESULTS: A total of 122 LGMDD1 patients were included from …

Missed Opportunities In The Diagnosis Of Tuberculosis Meningitis, Niamh Simmons, Margaret A Olsen, Joanna Buss, Thomas C Bailey, Carlos Mejia-Chew

2020-Current year OA Pubs

BACKGROUND: Tuberculosis meningitis (TBM) has high mortality and morbidity. Diagnostic delays can impact TBM outcomes. We aimed to estimate the number of potentially missed opportunities (MOs) to diagnose TBM and determine its impact on 90-day mortality.

METHODS: This is a retrospective cohort of adult patients with a central nervous system (CNS) TB

RESULTS: Of 893 patients with TBM, median age at diagnosis was 50 years (interquartile range, 37-64), 61.3% were male, and 35.2% had Medicaid as primary payer. Overall, 407 (45.6%) had a prior hospital or ED visit with an MO code. In-hospital 90-day mortality was not different between those …

Challenging Racism As A Black Police Officer: An Emergent Theory Of Employee Anti-Racism, Melanie K. Prengler, Nitya Chawla, Angelica Leigh, Kristie M. Rogers

Management Faculty Research and Publications

Organizations are key mechanisms by which racism is enacted and perpetuated. Although much of the management literature has focused on organizational efforts to combat racial discrimination, some of the most transformative changes come from the everyday actions of employees themselves. In this study, we develop grounded theory on racial minority employees who choose to challenge racism from within the organizational structures that perpetuate it most (i.e., highly racialized organizations). We present a theoretical model of employee anti-racism that emerged from our analysis of qualitative data—comprising 80.7 audio hours from 48 interviews with Black law enforcement officers. This model articulates anti-racism …

Do We Need Patient-Specific Qa For Adaptively Generated Plans? Retrospective Evaluation Of Delivered Online Adaptive Treatment Plans On Varian Ethos, Xiaodong Zhao, Dennis N Stanley, Carlos E Cardenas, Joseph Harms, Richard A Popple

2020-Current year OA Pubs

BACKGROUND: The clinical introduction of dedicated treatment units for online adaptive radiation therapy (OART) has led to widespread adoption of daily adaptive radiotherapy. OART allows for rapid generation of treatment plans using daily patient anatomy, potentially leading to reduction of treatment margins and increased normal tissue sparing. However, the OART workflow does not allow for measurement of patient-specific quality assurance (PSQA) during treatment delivery sessions and instead relies on secondary dose calculations for verification of adapted plans. It remains unknown if independent dose verification is a sufficient surrogate for PSQA measurements.

PURPOSE: To evaluate the plan quality of previously treated …

Analysis Of Early Childhood Education And Learning Outcomes In The Pacific, Dan Cloney, Yung Nietschke, Jeffery Marshall

Early Childhood Education

There is strong evidence supporting early childhood education (ECE) programmes as an effective way to support children to have the best start in life, especially for the most disadvantaged children. When high‐quality programmes are established – where quality is assured, and barriers to participation eliminated – large positive effects are observed that are sustained into adulthood. Indeed, substantial positive returns on public investment in ECE programmes are reported. When low‐quality programmes are taken to scale in the market, however, smaller effects or no effects are observed. This is attributed to failure to get quality right. And when quality is too …

Jesus Tribe, Christopher Richardson

Doctor of Ministry

Christians and churches in the early twenty-first century seem to belong to various tribes which leads to confused, disjointed loyalties. This confusion can lead to acrimony within churches. To develop and maintain the unity spoken of by Jesus Christ, these groups would benefit by better understanding and recognizing the prevalence of tribalism. Further, this should lead to the instigation of processes by which they can effectively evaluate and re-align their tribal loyalties toward a more definitive and effective modeling of Jesus and his lordship. Church leadership will benefit from a better understanding of the forces of tribalism at work both …

The Loft: Where Gen Z Goes To Build Relationships And Discover Spiritual Truths, Jeremy S. Deweerdt

Doctor of Ministry

It is an alarming but indisputable fact that the vast majority of Generation Z, specifically those between ages 18 and 25, are not attending and/or not interested in the faith or beliefs of the American Protestant Church today. Studies show that the Western Christian church is losing touch with an entire generation and that reality is the driving force behind this research project. We know from research conducted for this Doctoral Project, as well as from multiple academic and sociological studies that members of Generation Z are often interested in spirituality but are either ignorant or highly skeptical of organized …

Belonging: The Heart Of Our Family Calling, Janice M. Brewer-Stevens

Doctor of Ministry

Transracial families are part of our society whether people like it or not. There are not enough adoptive families of any kind, and children need support, love, and acceptance. Last August the Census Bureau reported that the number of non-Hispanic Americans who identify as multiracial jumped by 127 percent over the last decade, and for people who identified as Hispanic, the increase was even higher. Also, from 2017 to 2019, half of all U.S. adoptions were of non-white children, and half of these adoptions were transracial. The result? An increase in transracial adoptions in the United States and the subsequent …

Choline Supplementation Alters Hippocampal Cytokine Levels In Adolescence And Adulthood In An Animal Model Of Fetal Alcohol Spectrum Disorders, Jessica A. Baker, Tamara S. Bodnar, Kristen Breit, Joanne Weinberg, Jennifer D. Thomas

Psychology Faculty Publications

Alcohol (ethanol) exposure during pregnancy can adversely affect development, with long-lasting consequences that include neuroimmune, cognitive, and behavioral dysfunction. Alcohol-induced alterations in cytokine levels in the hippocampus may contribute to abnormal cognitive and behavioral outcomes in individuals with fetal alcohol spectrum disorders (FASD). Nutritional intervention with the essential nutrient choline can improve hippocampal-dependent behavioral impairments and may also influence neuroimmune function. Thus, we examined the effects of choline supplementation on hippocampal cytokine levels in adolescent and adult rats exposed to alcohol early in development. From postnatal day (PD) 4-9 (third trimester-equivalent), Sprague-Dawley rat pups received ethanol (5.25 g/kg/day) or sham …

Elements Of Higher Homotopy Groups Undetectable By Polyhedral Approximation, John K. Aceti, Jeremy Brazas

Mathematics Faculty Publications

When nontrivial local structures are present in a topological space X, a common approach to characterizing the isomorphism type of the n-th homotopy group πn(X, x0) is to consider the image of πn(X, x0) in the nth Cˇ ech homotopy group πˇ n(X, x0) under the canonical homomorphism 9n : πn(X, x0) → πˇ n(X, x0). The subgroup ker(9n) is the obstruction to this tactic as it consists of precisely those elements of πn(X, x0), which cannot be detected by polyhedral approximations to X. In this paper, we use higher dimensional analogues of Spanier groups to characterize ker(9n). In particular, …
