Deep Learning-Based Burned Area Mapping Of California Wildfires Using Sentinel-2 And Landsat-8 Imagery Enhanced With Super-Resolution Techniques, Youngmin Seo, Seung Hee Kim, Menas Kafatos, Jinsoo Kim, Yangwon Lee

Institute for ECHO Articles and Research

The increasing frequency of wildfires under a changing climate has led to extensive ecosystem destruction, highlighting the need for reliable burned area assessment using satellite imagery. Single-satellite data are constrained by observation gaps and interference from smoke and clouds, whereas multi-satellite data fusion can mitigate these limitations. Nonetheless, the fusion techniques still encounter challenges such as spatial information loss from resolution differences and cross-satellite domain mismatch. This study presents a burned area mapping framework that integrates super-resolution (SR) with transfer learning to address spatial and domain gaps in multi-satellite data. Specifically, Landsat-8 imagery is super-resolved to 7.5 m resolution, and …

Advancing Clean Mobility: Hydrogen Fuel Cell Electric Bus Workforce Development For Transit Agencies, Manideep Tummalapudi, Shantanu Kumar, Jaskaran Singh

Mineta Transportation Institute

Hydrogen fuel cell electric buses (FCEBs) are rapidly transforming public transportation in the United States. However, while transit agencies are investing heavily in new zero-emission vehicles and fueling infrastructure, far less attention has been paid to the workforce needed to operate and maintain them. As agencies accelerate toward ambitious climate and fleet transition goals, they are also confronting a critical challenge: preparing workers for an entirely new set of technologies, safety requirements, and operational demands. This study addresses that gap by systematically identifying the knowledge, skills, and abilities (KSAs) required for FCEB vehicle operators and maintenance technicians, assessing current training …

Heritable Transgenic Schistosomes As A Living Platform For Sars-Cov-2 Neutralizing Antibody Secretion, Wannaporn Ittiprasert, Bruce A Rosa, Sergej Djuranovic, Makedonka Mitreva, Et Al.

2020-Current year OA Pubs

We report the generation and propagation of not only the first heritable transgenic schistosome line but also a line that secretes a functional therapeutic protein in vivo. Using multiplexed CRISPR/Cas-mediated homology-directed knock-in targeted to a predicted genomic safe-harbor, we inserted a VHH-IgG1 Fc (termed C5-Fc) transgene into Schistosoma mansoni eggs. Single-miracidium infections of Biomphalaria glabrata yielded parental P0 lines; serial passage through snail and mouse hosts produced an F2 cohort in which all parasites carried the C5-Fc transgene and secreted C5-Fc into the murine venous circulation. Molecular assays confirmed chromosomal insertion, germline transmission and systemic secretion. Sera from mice harboring …

Allograft Tendon Pretensioning Technique Guide., Joseph R Brown, Robert W Mendicino

Surgery Articles

In foot and ankle surgery, allograft tendons are frequently used in both primary and revision cases to enhance stability and function. However, postoperative complications, such as creep, can compromise the intended correction and stability over time. This paper presents a practical guide on pretensioning techniques prior to implantation, aiming to reduce creep and improve long-term outcomes. Using two common allograft specimens, we demonstrate pretensioning methods with specific focus on tendon stitching, techniques for securing the allograft to the graft board, optimal tensioning and time parameters. We recommend pretensioning at 80 N for approximately 30 min to effectively decrease creep and …

Translational Initiative To Minimize Childhood Hemiparesis After Asymmetrical Perinatal Brain Injury, Susan V. Duff, Emily Garavatti, Terrie Inder

Physical Therapy Faculty Articles and Research

The purpose of this perspective paper is to present a translational approach aimed at identifying the critical periods in brain development during which to provide neuroprotective and neurorestorative strategies, followed by prehensile training, to minimize hemiparesis and foster skill acquisition after asymmetrical perinatal brain injury (APBI). We contend that hemiparesis could be minimized after APBI through a multimodal sequential approach based on timely implementation of evidence-based intervention strategies. If APBI is identified early, neuroprotective techniques can be used in the first 10 days of life to minimize cell death. This can be followed in the next 3 months by the …

Neuronal Expression Of Bromodomain Proteins Alters Neuronal Health And Peripheral Protein Homeostasis To Promote Longevity, Naibedya Dutta, Daniel Hicks, Edgar Esparza, Anna Entin, Priyadharshini Vijayakumar, Caitlin M Lange, Tripti Nair, Elijah A Roditi, Athena Alcala, Maxim Averbukh, Matthew Vega, Rebecca Aviles Barahona, Caitlin Mctygue, Veronica Kuo, Juri Kim, Herbert Anson, Aeowynn J Coakley, George Wang, Steven E Pilley, Max A Thorwald, Whitaker Cohn, Sean P Curran, Nicolas Brouilly, Caroline Kumsta, Rachel N Arey, Peter J Mullen, Gilberto Garcia, Ryo Higuchi-Sanabria

Faculty, Staff and Students Publications

Longevity and stress resilience require precise coordination of gene expression programs across tissues. Here, we demonstrate that overexpression of the chromatin reader bet-1 specifically in neurons of Caenorhabditis elegans promotes organismal longevity and stress resistance via cell-nonautonomous signaling. Neuronal bet-1 elicits a neurotransmitter-dependent signal that activates the conserved stress-responsive transcription factor HSF-1 in the intestine, enhancing proteostasis, oxidative stress resistance, metabolic remodeling, and immune defense. Life span extension by neuronal bet-1 requires both hsf-1 and daf-16 in neurons but only requires hsf-1 in peripheral tissues. Using bulk RNA sequencing, we reveal distinct prolongevity pathways that include enhanced heat-shock response, proteostasis, …

What Can You Say When You Can't Say Everything?, Lori Dorfman, Liana B. Winett, Katherine Schaff, Pamela Mejia

OHSU-PSU School of Public Health Faculty Publications and Presentations

Today's decisions about what and how to communicate about population health occur amid very real fears and expectations of harsh reprisal that have had far-reaching impacts, both for people's health and for the health professions. It is in this context that health researchers must share their findings with the public and policy makers, prevent confusion, and avoid harming groups already facing systemic barriers to health. In every communication context-from research papers to quotes on the nightly news-people must make thoughtful choices about what to say. Communication, therefore, is always an act of selection that requires both a clear purpose and …

Altered Postnatal Chromatin Development In The Nucleus Accumbens Primes Enduring Stress Sensitivity, Rebekah L Rashford, Lisa Z Fang, Michael Deberardine, Hye Ji J Kim, Laura W Hirschfield, Ella Cervi, Mason R Barrett, Jeremy M Thompson, Meaghan C Creed, Catherine Jensen Peña

2020-Current year OA Pubs

Early life stress (ELS) sensitizes individuals to subsequent stressors to increase lifetime risk for psychiatric disorders. Within the nucleus accumbens (NAc)-a key limbic and reward-associated brain region-ELS sensitizes both cellular and transcriptional response to later stress, which are programmed by enduring epigenetic changes. Among the histone modifications persistently enriched by ELS in NAc is H3K4me1, which is associated with open chromatin and epigenetic priming of genomic enhancers. Here, we sought to determine whether H3K4me1 enrichment in NAc was sufficient to prime cellular and behavioral responses to adult stress. Viral-mediated overexpression of the histone H3 monomethyltransferase

Lightweight Open Source On-Spacecraft Machine Learning With Mlpack And F Prime, Ryan R. Curtin, Scott M. Gilliland, Sterling L. Peet

Small Satellite Conference

Onboard machine learning is an increasingly important topic in spaceflight systems, as machine learning and AI models are increasingly used for data processing, anomaly detection, attitude control systems, and other predictive applications. However, successfully deploying a machine learning model in a spaceflight computing environment is fraught with difficulty, as spaceflight computing environments are low-resource, but typical machine learning software solutions are implemented in languages like Python, which require an interpreter and other heavyweight dependencies. It is therefore virtually mandatory for any on-spacecraft machine learning to be written with lightweight toolkits that minimize dependencies and resource usage.

We demonstrate a solution …

Software Defined Swarms, Nathan Benz, Scott Miller, Jeff Huang, Sonny Hwang, Todd Sarshad, Edmund De La Cruz, Thomas Magesarcher

Small Satellite Conference

The Starling Extended Mission has demonstrated the transformative potential of software-defined architectures in multi-spacecraft swarms. Building on the original Starling mission, which validated autonomous coordination and networking among small satellites, the extended phase focused on adaptability—updating onboard payload software and software-defined radios (SDRs) to enable entirely new experiments without hardware modifications. This capability signals a new approach: spacecraft swarms can evolve post-launch to meet emerging scientific and operational objectives. 

Central to this extension was the deployment of new software enabling two-way ranging and “reverse GPS” source identification using raw radio frequency (RF) signals. Traditionally, ranging and navigation rely on pre-integrated …

Small Satellite Conference

As Planet operates the world's largest commercial Earth observation satellite fleet, the transition from manual mission operations to autonomous systems has become a cornerstone of the ability to image Earth’s landmass each day. Planet operates a constellation consisting of hundreds of Dove satellites, approximately 15 SkySats, and a growing number of Pelican and Tanager satellites. As these on-orbit assets grow in both number and complexity, the move toward heterogeneous fleet management has required a unified approach to automation that spans across diverse satellite architectures concurrently and seamlessly. 

Drawing on the robust heritage of its large-scale Dove constellation, Planet has evolved …

Design Mechanism Framework For Autonomous Small Satellite Constellations – A Newspace Outlook, Mohammed Irfan Rashed

Small Satellite Conference

The increasing deployment of small satellite constellations is driving a transition from isolated spacecraft missions toward distributed and coordinated space operations. However, as constellation size and mission complexity grow, traditional ground-centric operational approaches become difficult to scale due to communication limitations, delayed decision-making, and increased operational workload. While autonomy has been widely explored through onboard algorithms and artificial intelligence techniques, there remains limited focus on how autonomy should be integrated into the systems engineering architecture of constellation missions. This paper presents a Design Mechanism Framework (DMF) for autonomous small satellite constellations that embeds autonomy directly into mission architecture, operational logic, …

Satellite Constellations 2026 - Survey, Trends And Economic Viability, Erik Kulu

Small Satellite Conference

This paper presents the commercial satellite constellation landscape as of Jan 1, 2026. It is based on data from the public NewSpace Index (www.newspace.im), which has tracked commercial constellations since 2016 and contained 456 entries by the end of 2025. 

Many constellation operators have launched initial satellites or small batches, but only a few have reached regular launch rates. Deployment has generally been slower than announced, with many projects scaling back plans or delaying timelines. SpaceX has a significant lead, having launched more than 11,000 Starlink satellites. The next largest commercial operators, Planet and OneWeb, remain well below 1000 satellites. …

The extragalactic background light (EBL) (Fig. 1) is the diffuse light arriving from outside our Galaxy. Previous studies revealed that the near-infrared EBL is several times brighter than the integrated galaxy light (IGL).

This excess may originate from the first stellar objects in the early universe or from intrahalo light. Their spectra differ in the visible range (Fig. 2), so the visible EBL is the key to identifying the origin.

Ground-based observations are contaminated by foregrounds such as airglow. We therefore developed VERTECS (Visible Extragalactic background RadiaTion Exploration by CubeSat) to observe the EBL from space.

Back From The Dead: Using Stellar Psf Calibration To Recover Operational Value From A Defocused Skysat Telescope, Phillip Linden, Hira Nadeem, Ross Losher, Venkataraman Krishnaswami

Small Satellite Conference

For large-scale Earth observation constellations, such as Planet’s SkySat fleet, a major challenge is mitigating the effects of post-launch optical aberrations, which can render an asset unusable. This paper presents a novel approach to recover operational value from SkySat-C5, which remained excluded from production for 8 years due to significant, uncorrectable focus deficit at launch. Our method leverages stars to calibrate a reliable Point Spread Function (PSF) used in a deconvolution process that restored the camera’s images to a usable level of quality.

Because there is no on-orbit focus mechanism, the only path to restoration is post-processing deconvolution using a …

From Competition To Complementarity: A Case Study Of Arabic-English Language Ideologies At University Of Bisha, Ahmed Yahya Mohammed Al-Hakami

UB Journal for Humanities

This study investigates the coexistence of, and tension between, Arabic and English language ideologies in Saudi higher education, focusing on University of Bisha as a case study. Drawing on quantitative data from online questionnaires (N = 138), this study examines how Arabic and English are ideologically valued, legitimised, and contested across three dimensions, namely identity, academic learning, and status. Using robust statistical analyses, including correlation and repeated-measures testing, the analysis tests whether these ideologies function primarily as competing forces, privileging one language at the expense of the other, or as complementary resources that support students’ academic experience and professional ambition. …

Education, Health & Behavior Studies Faculty Publications

Student engagement in developing open educational resources (OER; openly licensed materials without fees to access) may be critically important for sustainable higher education and for developing important skills. There has been substantial debate about the use of generative artificial intelligence (GenAI) for the sustainability of OER, but little empirical inquiry. In this quasi-experimental study in the United States, two sections of college students (N = 113) collaborated with their instructor to improve the sources cited in an OER textbook. In one section, students only used traditional library databases to find suitable sources (traditional; n = 55). In another section, students …

The Mundlak Estimator In A Panel Data Model With Serially Correlated Error Component Disturbances, Badi H. Baltagi, Long Liu

Center for Policy Research

This paper shows that the classic Mundlak (1978) result where the random effects estimator reduces to the fixed effects estimator when the regressors are all correlated with the individual effects, may not hold if the remainder disturbances have a general serial correlation variance-covariance matrix. This includes the popular AR(1), MA(1) and ARMA(p, q) processes for serial correlation. This is illustrated with an empirical example for the AR(1) case.

Adherence To Evidence-Based Practice In Childhood Immunization: A Mixed-Methods Study, Lydia Boampong Owusu

International Nursing Research Congress (INRC)

Immunization is one of the most effective public health measures for preventing infectious diseases in children (Baidya et al., 2024). Immunization safety and effectiveness depends on proper injection site management (Rishovd, 2014; World Health Organization, 2018). Globally, Evidence-Based Practices (EBP) are recommended to enhance immunization effectiveness and minimize unwanted side effects (Cataldi et al., 2020). However, there is a dearth of empirical evidence on healthcare provider adherence to EBP in injection site management which presents a significant knowledge gap, especially in developing countries. This study assessed the experience and understanding of healthcare providers' adherence to EBP in administering childhood vaccines …
