Energy-Harvesting Concurrent Lora Mesh With Timing Offsets For Underground Mine Emergency Communications, Hilary Kelechi Anabi, Samuel Frimpong, Sanjay Madria

Mining Engineering Faculty Research & Creative Works

Underground mine emergencies destroy communication infrastructure when situational awareness is most critical. Current systems rely on centralized network infrastructure, which fails during emergencies when miners are trapped and require rescue coordination. This paper proposes an energy-harvesting LoRa mesh network that addresses self-powered operation, interference management, and adaptive physical layer optimization under severe underground propagation conditions. A dual-antenna architecture separates RF energy harvesting (860 MHz) from LoRa communication (915 MHz), enabling continuous operation with supercapacitor storage. The core contribution is a decentralized scheduler that derives optimal timing offsets by modeling concurrent transmissions as a Poisson collision process, exploiting LoRa's capture effect …

Fisheries Research Report No. 355: Recreational Fishing For Western Rock Lobster In 2024/25: Estimates Of Participation, Effort And Catch, Claire B. Smallwood, Karina L. Ryan, Alissa Tate

Fisheries Research Reports

The Western Rock Lobster (WRL) (Panulirus cygnus) is the most commonly caught Rock Lobster (RL) species in Australia. Catches from the commercial and recreational sectors are required to determine and monitor Total Allowable Commercial Catch (TACC), Total Allowable Recreational Catch (TARC) and the proportion of Allowable Harvest Level (AHL) achieved. The TARC is evaluated annually based on a 5-year average.

Data for the recreational sector are obtained using phone-recall surveys to provide annual estimates of participation, fishing effort and retained catch (by numbers) from recreational fishers who hold a RL licence. Average weight, obtained from boat ramp surveys, are used …

Small For Gestational Age Subgroups Have Differential Morbidity, Growth, And Neurodevelopment At Age 2: The Interbio-21st Newborn Study, Aris Papageorghiou, María Restrepo-Méndez, Rose Mcgready, Fernando Barros, Francois Nosten, Shama Munim, R. Ochieng, Rachel Craik, Hellen Barsosio, James Berkley

Paediatrics and Child Health, East Africa

BACKGROUND: Small for gestational age is a complex perinatal syndrome associated with increased neonatal morbidity, mortality, and impaired childhood growth and neurodevelopment. Current classifications rely primarily on birthweight, which does not capture the heterogeneity of the condition nor predict long-term health outcomes. Here we aim to identify and characterize distinct small for gestational age subgroups and assess their neonatal and early childhood health trajectories.

OBJECTIVE: To refine the classification of small for gestational age by identifying subgroups based on maternal, fetal, and environmental factors and evaluating their associations with neonatal morbidity, growth, and neurodevelopment at age 2.

Recycling Waste Via Insect Agriculture: Frass Impacts On Soil And Plant Health, Helen C.S. Amorim, Amanda J. Ashworth, Thomas F. Ducey, Valerie B. Brewer-Gunsaulis, Gerson L. Drescher, Philip R. Owens, Alana H. Patterson, Giovanna De Blais, Iris Van Straaten

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Frass-the main by-product of insect rearing for animal feed-is emerging as a promising soil amendment and plant growth promoter. However, basic agronomic information is lacking and prevents frass' widespread use as a biofertilizer. This study assessed impacts of black soldier fly (Hermetia illucens L. [Diptera: Stratiomyidae]) frass on soil fertility, crop growth, and quality compared to poultry litter (PL). Irrigated and non-irrigated soybean (Glycine max L. Merr.) and non-irrigated switchgrass (Panicum virgatum L.) plots received either PL (5.6 Mg ha(-1)), low frass rate (LF; 5.6 Mg ha(-1)), high frass rate (HF; 11.2 Mg ha(-1)), besides the unamended control (CT). In …

Findings From A Pilot Project Highlight Lessons To Ensure Safe Cleaning Practices And Pesticide Use In At-Home Childcare Centers, Elizabeth Friedman, Luke Gard, Sherri G. Homan

Manuscripts, Articles, Book Chapters and Other Papers

Lead and pesticide exposure are leading environmental health concerns for children, and these exposures can result in long-term health consequences, including irreversible cognitive delay and endocrine dysfunction. A pilot program aimed to a) develop and disseminate educational materials and supplies and b) perform in-home childcare facility assessments to increase knowledge regarding lead and pesticide safety, provide education on the health impacts of elevated blood lead levels, and reduce exposure risks in these settings. The program was implemented in St. Louis, Missouri. From outreach and education efforts to interactive feedback, this article shares important lessons learned and highlights educational gaps that …

Intraoperative Electrical Stimulation Can Identify Potential Ulnar Nerve Injury From Crossed Pinning Of A Supracondylar Humerus Fracture., Lucas A. Georger, Mckenna C. Noe, Richard M. Schwend

Manuscripts, Articles, Book Chapters and Other Papers

Treatment of Gartland type III supracondylar fractures using reduction and crossed Kirschner wire fixation is considered the most stable method; however, there is a risk of iatrogenic ulnar nerve injury during medial pin placement. We describe a technique for intraoperative detection of such nerve injury.An inexpensive disposable nerve stimulator is set at 2 mA and applied directly to the Kirschner wires after placement, alerting the surgeon intraoperatively if a wire contacts the ulnar nerve. A positive response involves any finger motion with Kirschner wire stimulation. We recommend this novel method of intraoperative Kirschner wire stimulation using an inexpensive disposable nerve …

Ceo-Board Political Alignment And Firm Performance: An Examination Of Declines From Homogeneity That Are Mitigated By Ceo Psychological Traits, James Grabowski, Christina Robichaud, David B. Wangrow

Management Faculty Research and Publications

As people group themselves by their political ideologies, ideological alignment is likely to occur in workgroups—including boards of directors. While some research highlights positive outcomes from shared group characteristics, homogeneity can also hinder decision-making due to fewer perspectives being considered, limited sharing of non-conforming information, and narrowed problem solving. Building from prior research, we contend that substantial political alignment between a CEO and board members aligns them toward a common cognition, which fosters negative effects associated with homogeneity and subsequently reduces firm performance. We further contend that these performance reductions can be mitigated by psychological traits associated with managerial discretion. …

High-Energy And On The Move: Exploring The Kinematic And X-Ray Properties Of Young Stars Near Earth With Gaia, Chandra, And Erosita, Attila Vincent Varga

Theses

Young stars in the solar neighborhood provide a unique and insightful window into stellar evolution during the first few hundred million years after formation. Leveraging archival photometric and astrometric data from ESA’s Gaia Space Astrometry mission, as well as photometric data from NASA (2MASS and WISE) archives, I have identified over 50 new members of the nearby (D ∼ 100 pc), 3–8 Myr-old Epsilon Cha association (ECA), including six new proto-brown dwarf candidates. By modeling the kinematics and photospheric properties of both newly identified and previously known members of the ECA and Lower Centaurus Crux (LCC), I further established the …

A Cross-National Study Of Female Fertility Intention And Family Welfare Policies In China And South Korea, Jingshuang Gao

SOC 605 Comparative Social Policy Research Project - Student Works

Against the backdrop of chronically low fertility rates in China and South Korea, this study investigates the relationship between female fertility intentions and family welfare policies in these two East Asian societies. It aims to identify the multidimensional challenges women face, analyze the disjuncture between existing fertility support policies and women's fundamental needs, and propose pathways for policy optimization. Employing a mixed-methods approach including online observation, critical discourse analysis of policy texts, and small-scale semi-structured interviews, the research reveals that women's fertility intentions are constrained by physiological risks, economic pressures, the cultural expectations of "motherhood," and conflicts with personal development. …

Disuse muscle atrophy secondary to acute illness or injury prolongs recovery and increases risk of permanent disability as a result of reduced muscle strength and myofiber damage upon reambulation. However, there are no pharmacotherapies to support muscle growth and repair following prolonged immobility. We propose that all-trans retinoic acid (ATRA) may support recovery of atrophied muscle via modulation of satellite cells and macrophages. Clinical application of ATRA is hindered by solubility, stability, and the need for high systemic doses. Therefore, in the current study, we developed poly(lactide-co-glycolide) (PLG) particles for local injection and extended release of ATRA (ATRA-PLG) and investigated …

The Helsinki Accords Turned Fifty. How Should We Celebrate It?, Paul Rubinson

Bridgewater Review

In 2023, Lech Walesa spoke at BSU. More than anything else that night, I remember the ovation. The cheering lasted so long that at one point Walesa slowly checked his watch, as if to ask How long will this go on? Walesa is probably one of the few human beings who merits such adulation. His stubborn defiance in organizing non-communist trade unions eventually forced his government to concede and recognize them in the Gdansk agreement of 1980. A Nobel Peace Prize followed in 1983, and he was elected Polish president in free elections in 1990.

Does A Ceo Turnover Lead To A Cfo Turnover? Evidence From Voluntary And Forced Turnover, Bakhtear Talukdar, Sabur Mollah, Suchismita Mishra, Junhong Yang

Management Faculty Publications

The role of CFO has become increasingly important since the enactment of SOX 2002. The existing literature suggests that CFOs tend to leave office within 6 to 12 months of a CEO’s departure, but studies addressing whether forced and voluntary turnover behave differently are unexplored. There is also no attempt to explore whether financial performance or institutional shareholding play moderating roles in mitigating successive CFO and CEO turnovers. These scholars find that forced (voluntary) CEO turnover has a higher significant marginal effect on forced (voluntary) CFO turnover. They also find that, in general, higher financial performance and institutional ownership play …

This article outlines a practical, evolving approach to building librarian support for systematic reviews, developed in response to program needs and professional learning. It highlights strategies for designing low-barrier instruction, guiding students through foundational concepts like structured research questions and transparent search methods, and introducing free tools such as Rayyan and Mendeley to streamline the process. The article also explores the emerging role of artificial intelligence in evidence synthesis, offering a cautious but …

The Effects Of Head Injury On Executive Function And Emotion Regulation In Male And Female Athletes, Anna Christine Speer

Doctor of Psychology (PsyD)

Head injuries are a common occurrence among athletes, and research on concussions has seen significant rise alongside an increasing awareness of their symptoms and effects. Women’s involvement in sports has also rapidly increased in recent decades. However, a significant gap in research exists as to how the effects of head injuries may differ across sexes, particularly regarding executive function and emotion regulation. This study aimed to bridge this gap in research by investigating how the frequency of head injuries in both female and male athletes impact executive functioning and emotion regulation among current and former athletes. Current and former athletes …

Health Disparity Indices In The Assessment Of Adolescent Idiopathic Scoliosis: Are All Indices Similar?, William Woodhams, Michael Benvenuti, Jonathan Warren, George Thomas, John Anderson, Richard M. Schwend, K Aaron Shaw

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is a common spinal deformity. Previous studies have demonstrated that healthcare disparities affect the initial presentation of AIS patients. However, studies have utilized various socioeconomic status (SES) indices with no previous study assessing the congruency of these indices.

METHODS: A single-center, retrospective review of adolescent patients presenting for initial evaluation of scoliosis was performed at a tertiary care pediatric hospital based in the central United States. Patient demographic data were recorded in addition to radiographic data consisting of coronal curve magnitude at presentation and skeletal maturity indices. Socioeconomic variables were collected, including geographic area of …

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: This study explores the psychosocial impact of a positive newborn screen (NBS) result for four lysosomal storage disorders (LSDs) (Fabry disease, Krabbe disease, Mucopolysaccharidosis Type I, Pompe disease) across confirmatory results.

METHODS: Parents whose child who had a positive NBS for one of the included LSDs were recruited for a retrospective cohort (n = 80) or prospective, longitudinal cohorts (n = 50). Surveys assessed uncertainty, anxiety, intrusive or avoidant thoughts, and perceived vulnerability of their child's health. In-depth interviews explored the NBS experience and psychosocial response.

RESULTS: Participants experienced uncertainty and anxiety during confirmatory testing that improved as parents …

Preoperative Immobilization For Pediatric Femur Fractures., Connor Mathes, Leilani Mansy, Lisa Berglund, Caleb W. Grote

Manuscripts, Articles, Book Chapters and Other Papers

Guidelines for the definitive surgical management of pediatric femoral shaft fractures have recently been established. Initial preoperative immobilization of these patients varies by age and size; limited guidelines exist to guide caregivers in appropriate preoperative care. Here, we present our recommendations based on clinical experience and literature review. We prefer temporary splints for patients younger than 5 years and Bucks boot traction for skeletally immature patients older than 5 years. In small patients, the splint should extend past the iliac crest and down to the foot to ensure proper immobilization of the femur fracture. For Bucks boot traction, proper traction …

Associations Between Perceived Stress And Glycemic Measures: Gender And Age As Moderators, Ming-Hong Tsai, Charlene Enhui Goh, Michelle H. Lee, Francine Seah, Maybritte Lim, Eveline Febriana, Jiahui Fu, Julie K. Yip, Philip Presham, Sue-Anne Ee Shiow Toh

Research Collection School of Social Sciences

Introduction Prediabetes presents an opportunity for early intervention. Growing evidence suggests that psychological stress may contribute to glucose dysregulation, but the findings are inconsistent. This study aimed to clarify the association between perceived stress and glycemic measures, by first testing gender as a moderator, and then examining age as a moderator within each gender group. Research design and methods We analyzed cross-sectional data from 470 diabetes-free adults in Singapore. Participants completed the 10-item Perceived Stress Scale, comprising two subscales: perceived helplessness and perceived self-efficacy. Glycemic measures included fasting plasma glucose, glycated hemoglobin, and 2-hour plasma glucose (2h-PG) following an oral …

Local-Thinking Bias, Ed Dehaan, Charles M. C. Lee, Wei Ting Loh

Research Collection School Of Accountancy

Local-thinking bias, wherein agents overweight information that comes readily to mind, is a prominent finding in cognitive psychology. In this study, we investigate local-thinking bias in the context of sell-side analysts and measure each analyst’s “local” information as news stemming from their individual coverage portfolio. Tests examining multiple analysts forecasting on the same focal firm at the same time find that individual analysts overweight idiosyncratic local news and underweight news from economically linked firms that are not in their coverage portfolios. Market prices track the analyst bias from local news, leading to predictable and economically significant return reversal patterns in …

Influence Of Organic Matter And Mineral Composition On Carbonate Source Rock Wettability: Implications For Co2 Geostorage, Muhammad Usman, Nurudeen Yekeen, Muhammad Ali, Mujahid Ali, Alireza Keshavarz, Stefan Iglauer, Volker Vahrenkamp

Research outputs 2022 to 2026

Wettability is critical in determining carbon dioxide (CO2) behavior during geological sequestration in unconventional reservoirs. Unconventional reservoirs are compositionally heterogeneous, affecting CO2 plume migration, containment security, and storage capacity during geological sequestration. Previous studies on CO2 storage in unconventional reservoirs have primarily attributed to changes in organic matter content; however, this study examines how variations in the mineralogical and organic matter content combined affect wettability in CO2/brine systems under subsurface conditions. Three samples with varied mineralogy and TOC content were selected from a well drilled in Jordan source rocks—an immature analog of marine-derived, carbonate-dominated, Type IIS source rocks. Samples were …

The Effect Of Proton Pump Inhibitors On Bone Mineralisation: A Systematic Review With Focus On Phospho1, Célia Baudin, Ricardo Faria-Almeida

Sultan Qaboos University Medical Journal

Objectives: Proton pump inhibitors (PPIs) are among the most widely prescribed drugs for long-term suppression of gastric acid. Though generally considered safe, increasing evidence links their use to altered bone metabolism. This systematic review investigates the hypothesis that PPI-induced inhibition on PHOSPHO1-a bone-specific phosphatase- impairs bone mineralisation. Methods: A systematic electronic search was conducted for experimental studies from January 2000 to January 2025. The screening and selection followed PRISMA guidelines. Results: Of 20 articles identified, 3 met the inclusion criteria: two in-vitro studies and one combining both in-vitro and in-vivo data. All three examined the effects of PPIs on bone …

Eugene Talmadge’S Library Book Purge Of 1941, David B. Parker

Georgia Library Quarterly

In Summer 1941, Governor Eugene Talmadge ordered a purging of 23 books from Georgia’s public school libraries. The books covered several subjects: race relations, sex education, evolution, South-bashing, states’ rights, communism, and more. He was planning on running for a US Senate seat in 1942, and perhaps he did this to attract voter support—showing that he would protect the state’s traditional values from various modern threats. There was immediate opposition, with many people comparing Talmadge’s ban to German Nazism.

Characterizing Piezoelectric-Blended Polydimethylsiloxane For Use As A Mechanoelectrical Responsive Cell Culture Substrate, Alexis P. Applequist, Lance D. Cordes, Lais A. Ferreira, Kartik Balachandran

Biomedical Engineering Faculty Publications and Presentations

In this study, we developed a piezoelectric-polydimethylsiloxane (pz-PDMS) composite by blending poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) with PDMS to create a biocompatible, mechanoelectrical responsive material. The pz-PDMS was synthesized with varying piezoelectric concentrations (0%, 1%, 3%, and 5%) and characterized for visual properties, mechanical properties, mechanoelectrical sensitivity, and biocompatibility. Compression testing showed no significant change in mechanical strength with the addition of piezoelectric particles, while mechanolectrical sensitivity testing revealed a non-linear increase in voltage response, with 5% pz-PDMS producing the highest sensitivity. Fatigue testing demonstrated no change in sensitivity after 7 days of cyclic displacement. Additionally, microcantilever experiments demonstrated the high fidelity …
