Physics & Astronomy Faculty Publications

Aims. K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star; however, it has remained poorly studied due to its faintness. The central star exhibits pronounced photometric variability whose origin is still unclear. We present a comprehensive characterisation of the K 1-6 system, including the physical properties of its stellar components and the nature of the surrounding nebulosity.

Methods. We conducted a multi-wavelength analysis combining optical and UV spectroscopy obtained with the Gran Telescopio Canarias, the Telescopio Nazionale Galileo, the Nordic Optical Telescope, and the Hubble Space Telescope. We also present long-term multi-band ground- …

A Deep Learning-Based Approach For Mapping Shrubs In Arctic Tundra From Very High-Resolution Imagery, Darko Radakovic, Mark Chopping, Bruce Cook, Aparna S. Varde, Stefan A. Robila

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Arctic shrub expansion is accelerating due to climate warming, but accurately mapping it at fine spatial scales remains challenging due to spectral overlap between shrubs and surrounding vegetation, heterogeneous tundra landscapes, and limited availability of very high-resolution imagery. This study presents a novel mapping and validation approach that integrates very high-resolution (< 1 m) QuickBird (QB) and WorldView (WV) satellite imagery across 12 North Slope sites, using deep learning architectures to map changes in shrub cover from 2002 to 2022. Deep learning models, including Convolutional Neural Network (CNN), ResNet, VGG, U-Net, and Vision Transformer, were trained on 4,100 3-channel pansharpened multispectral images (200×200 m). Two traditional machine learning models (Random Forest and Support Vector Machine) served as a control group. Leave-one-site-out cross-validation showed that all models performed well (AUC-ROC of 0.78–0.86, F1 at validation of 0.33-0.46) and had a moderate to strong agreement with field reference data (R2 = 0.76–0.87). The pretrained VGG and ResNet models achieved the strongest field-reference alignments for shrub cover prediction, while the difference with traditional models was small. Temporal trend analyses for July and August demonstrate a cover change of 0.06–0.45% yr-1 with unweighted mean area slopes and 0.01–0.92% yr-1 inverse-variance weighting. Growth rates were found to depend on the analytical design. Furthermore, the limiting factor in mapping shrub cover was not model complexity but the quality of the training data labels (annotation method explained ∼26% of the error variance). Per-scene cover error was seen across architectures (ρ = 0.67). Comparison with NASA Goddard's LiDAR, Hyperspectral and Thermal (G-LiHT)-derived Canopy Height Models revealed a weak-to-moderate relationship (R2 = 0.04–0.77), suggesting horizontal cover and vertical canopy structure capture complementary aspects of shrub abundance. These results demonstrate the potential of deep learning to map decadal shrub expansion at sub-meter resolution.

“Whenever You Are Using Media, You Should Always Have A Purpose”: A Study Of Chinese Immigrant Mothers’ Media Practices, Xiaoning Gui, Daniel G. Krutka

Journal of Media Literacy Education Pre-Prints

This qualitative study explores how eleven Mandarin-speaking Chinese immigrant mothers of young children in a southwestern U.S. city navigate and mediate media in their households. Data were collected through semi-structured interviews. Findings show mothers balance media’s educational affordances with concerns about health and age-appropriate content, employing gatekeeping, time limits, and purposeful sharing. Mothers described children as learners, co-learners, and cultural connectors, sometimes reversing mediation by teaching mothers about U.S. media norms. Interpreted through a lens of Culturally Sustaining Pedagogy while also drawing on Confucian concepts, results underscore the need for early childhood educators to honor immigrant families’ practices while fostering …

Industry Implications Of A Scaffolded Hospitality Co-Op, Juan Mendez, Joel Reynolds

ICHRIE Research Reports

The hospitality industry faces a persistent skills gap as graduates enter the workforce with limited preparation in the adaptive, operational, and AI-enabled competencies modern employers require (Jackson, 2013; Sigala, 2018). Cooperative education offers a structured response, yet many programs default to a single internship that leaves the integration of theory and practice to chance. This report presents an undergraduate scaffolded cooperative education framework developed at a U.S. hospitality business school that sequences two foundation courses, six concurrent work-integrated courses, and a capstone digital portfolio across a two-year arc. The framework is grounded in experiential learning and scaffolding theory (Kolb, 1984; …

Among people 25 or older in the United States in 2022, just 21% of individuals with a disability had earned a bachelor’s degree or higher, while 38% of individuals without a disability had earned a bachelor’s degree or higher. Previous research has identified a variety of barriers that students with disabilities may face as they pursue postsecondary education. The purpose of this study was to examine barriers students with disabilities (SWDs) face once they arrive at college in order to investigate how higher education may be made more accessible. Barriers were assessed by surveying SWDs attending James Madison University, a …

Phosphoric Acid-Mediated Regeneration Of Sugarcane Bagasse Cellulose-Rich Fraction For Enzymatic Production Of Water-Soluble Cellulosic Oligomers, Chiou-Yeong Saw, David Agus Setiawan Wibisono, Tsung-Yen Wu, Yung Chang, Chi-Fai Chau

Journal of Food and Drug Analysis

An integrated strategy was developed to promote conversion of a sugarcane bagasse cellulose-rich fraction into water-soluble cellulosic oligomers (WCOs) through phosphoric acid-mediated regeneration and enzymatic hydrolysis. Alkaline pretreatment on sugarcane bagasse powder increased glucan content from 57.6 to 93.4 g/100 g sample and lowered Klason lignin to 6.1 g/100 g sample. Phosphoric acid-mediated regeneration was subsequently capable of reorganizing the structure of cellulose from sugarcane bagasse, resulting in a decrease of crystallinity from 72.9 to 64.0% and introducing cellulose II-like features. The hydration state of regenerated cellulose strongly influenced hydrolysis performance, as the hydrated form showed significantly higher solubilization (810.4 …

In-Situ Metrological Reporting And Asset-Embedded Quality Annotation, Hp Inc

Defensive Publications Series

A surface-inspection system is described that acquires position-referenced measurements as it moves across a target surface, calculates local quality information while the measurements are acquired, and deposits localized markings at the corresponding physical positions. A controller combines coordinate and measurement data to maintain a surface map, applies selected acceptance criteria to local regions of that map, and generates marking instructions for a printer or other marking assembly. The markings may include numeric values, pass or fail symbols, contour lines, corrective-action regions, or machine-readable codes that identify the local data. The result is a persistent, surface-anchored quality record that can be …

Fully Anharmonic Infrared Spectra Of Neutral Polycyclic Aromatic Hydrocarbons With Up To 38 Carbons, Nolan J. H. White, Vincent J. Esposito, Christiaan Boersma, Louis J. Allamandola, Jesse D. Bregman, Alexandros Maragkoudakis, Pasquale Temi, Ryan Fortenberry

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Interstellar aromatic infrared band (AIB) spectra show agreement with presently computed anharmonic spectra for various types of polycyclic aromatic hydrocarbons (PAHs) determined using a novel semiempirical quantum chemical method. Since the AIB spectrum is a blend of emission spectra from a vast number of different PAHs, likely with an array of different molecular structures, the spectra for a sample set of 31 PAHs ranging in size from naphthalene (C₁₀H₈) up to circumbiphenyl (C₃₈H₁₆) are combined, giving consideration to almost all PAH structural motifs. The computed numerical quartic force fields coupled to second-order …

Quantum-Enhanced And Machine Learning Framework For High-Accuracy Fatigue Life Prediction And Structural Analysis Of Connecting Rod, P. H. J. Venkatesh, P. Seema Rani

Babylonian Journal of Mechanical Engineering

The connecting rod is a critical mechanical component that transmits reciprocating motion from the piston to rotational motion in the crankshaft. Although connecting rods are traditionally manufactured from aluminum alloys, titanium alloys, or alloy steels, the demand for higher power-to-weight ratios has motivated the exploration of alternative materials supported by advanced computational validation methods. This study proposes a multilayer optimization framework for identifying the most suitable material for the connecting rod of a 110 cc four-stroke petrol engine. The component was modelled in Pro/ENGINEER, and high-fidelity Finite Element Analysis (FEA) was performed in ANSYS to evaluate the von Mises stress, …

Molecular And Structural Basis For Replication Initiation And Strand Separation By Human Mitochondrial Dna Polymerase Γ, Viktoriia Sokolova, Gina Buchel, S. Strock, Ashok R. Nayak, Dmitry Temiakov

Department of Biochemistry and Molecular Biology Faculty Papers

Defects in human mitochondrial DNA (mtDNA) replication can lead to somatic mutations associated with a range of devastating mitochondrial diseases. However, the molecular mechanisms governing the earliest steps of mtDNA replication and their fidelity remain poorly understood. Here, we found that DNA polymerase gamma (Polγ) forms stable complexes with RNA-DNA primer-template substrates, exhibiting greater stability and lower misincorporation than on DNA-primed substrates. Structural analysis revealed that Polγ interacts with the 2'-OH groups of ribose within the first four nucleotides of the primer, explaining the stability of complexes that utilize RNA primers. Although Polγ requires TWINKLE to extend RNA primers, its …
