Experimental And Simulation Study On Energy Release Of Extended Sources Influenced By Atmospheric Pressure Variation, Kai Guo, Feiyu Zhao, Hao Zhang, Liang Wang, Kai Zhang

Journal of System Simulation

To investigate the energy release characteristics of extended sources in low-pressure environments, a combined experiment and simulation approach was adopted. Four typical altitudecorresponding pressures were selected as experimental conditions. An infrared thermal imager was employed to monitor parameters such as combustion temperature, radiance, and combustion area during the combustion process of the extended source. When the pressure decreases from 101 kPa to 30 kPa, the ignition time of the extended source doubles; the total energy release attenuates by 44.78%, and the combustion area reduces by 45.95%, but the fluctuations of peak temperature and average temperature are less than 3%, …

Research On Output Feedback Control Based On Reinforcement Learning For Overhead Crane, Minghui Li, Daoxiang Gao

Journal of System Simulation

An output feedback control algorithm is designed based on reinforcement learning for the optimal control problem of overhead crane system. A high gain observer (HGO) is designed using output data to estimate the unmeasurable states of the overhead crane system. Based on the estimated states from the high-gain observer, a policy iteration (PI) method is designed with integral reinforcement learning, which uses Critic and Actor neural networks to approximate the optimal value function and control strategy, and adjusts the neural network weights in real time through online adaptive algorithms. According to the Lyapunov stability theory, the uniform ultimate boundedness of …

Current Status And Prospects Of Complex Scene Reconstruction Based On Gaussian Splatting, Hong'an Li, Jiale Yang, Qingfang Liu, Yu Shi

Journal of System Simulation

Three-dimensional Gaussian splatting (3DGS) provides an alternative approach for novel view synthesis from the perspective of explicit representation. By reconstructing scenes using 3D Gaussian primitives and replacing traditional ray integration with a point-based rasterization process, it not only improves training and rendering efficiency but also offers new insights for complex scene reconstruction. This paper divided 3DGS-based complex scene reconstruction methods into three major categories and elaborated on them around large-scale scenes, sparse views, and dynamic scenes. It reviewed the current development status of this field and pointed out possible future research directions.

Laminarin-Loaded Solid-In-Oil Nanodispersion For Enhanced Non-Invasive Transdermal Immunization, Md. Shahin Ekka Sarker, Yoshirou Kawaguchi, Rie C. Wakabayashi, Noriho J. Kamiya, Muhammad Moniruzzaman, Masahiro Goto

Publications and Research

Simple and non-invasive transdermal vaccination is an attractive alternative to conventional injection-based immunization. However, the effectiveness of transdermal vaccines is often constrained by the stratum corneum barrier. Although the use of solid-in-oil (S/O) nanodispersion technology has successfully facilitated skin permeation to induce an immunological response, the antibody titers remain suboptimal. Herein, a dectin-1 selective ligand, laminarin, was used as an immunostimulatory adjuvant to enhance the immune response. S/O nanodispersions loaded with laminarin and ovalbumin (OVA) were systematically developed and characterized in terms of particle size, in vitro OVA release behavior, and skin permeation performance using excised mouse skin. In vivo …

Temporal And Spatial Variation In Temperature And Oxygen At The Microscale: Key Niche Axes For Aquatic Life, W. C.E.P. Verberk, David T Bilton

School of Biological and Marine Sciences

To understand animal adaptations, we need accurate estimates of the ecological factors impacting organisms in nature. While temperature is a well-established driver of physiological performance, its effects in aquatic systems are closely linked to water oxygenation. Oxygen levels are expected to differ spatially and fluctuate temporally much more strongly in water than on land, but our understanding of variation in temperature and oxygen levels in freshwaters remains limited. It is essential that environmental variation is recorded at spatial and temporal resolutions relevant to the organism. Here, we analyse spatial and temporal variation in water temperature and oxygenation across running and …

Animal Ethics And The Lowest Common Denominator, John O. Adenitire

Animal Sentience

This commentary assesses the pragmatic framework proposed in Jonathan Birch’s The Edge of Sentience (2024). Celebrating the book's exceptional clarity, scientific rigor, and profound real-world impact on UK legislation, I nevertheless have some questions about the method by which Birch arrives at his policy recommendations for animal protection. In seeking an overlapping consensus between deeply divergent ethical and credal viewpoints, the framework risks defaulting to a minimalist, lowest-common-denominator standard of protection for animals. Birch also risks drawing the standard even lower by including serious academic positions in animal ethics that deny moral status for animals altogether. A rights-based approach offers …

Humor In Eighteenth-Century Dress: The Comic Form Of Beethoven’S Grosse Fuge, Op. 133., Stephen Husarik

HAYDN: Online Journal of the Haydn Society of North America

Beethoven’s Grosse Fuge (Op. 133), previously interpreted as a work shaped by comedic design, can also be understood as an “algorithmic fugue” in which the subject undergoes a systematic process from deformation to restoration. Rather than relying mainly on traditional contrapuntal devices such as inversion and augmentation, Beethoven reshapes the theme through syncopation and paired slurred pulses, then expands these alterations into increasingly exaggerated fugal textures. Drawing on sketches and manuscript sources, this paper argues that the process resembles the moves of a Rubik’s Cube, with each transformation contributing to an eventual solution. In the closing measures, Beethoven reverses the …

What’S Past Is Prologue: Prior Convictions As Evidence Of Dangerousness In State V. Romero, Alexander Guel-James

New Mexico Law Review

State v. Romero marked the first time the New Mexico Court of Appeals considered whether a New Mexico law disarming every person with a state felony conviction was unconstitutional under the Second Amendment. The court upheld the law, but only to the extent that it disarmed dangerous felons. The court found that the appellant was dangerous because he was previously convicted of dangerous crimes. This note questions whether prior convictions alone are sufficient to prove dangerousness. Criminal justice data and constitutional theory caution against dangerousness findings based on criminal history alone. Courts should determine dangerousness under the disarmament law using …

Bullying Prevalence And Persistence In Rural And Urban Settings, Eric Landers, Juliann Sergi Mcbrayer, Monika Krah, Meredith A. Rausch

The Rural Educator

Bullying is a serious issue in schools, affecting students’ physical health, academic performance, and mental well-being. It involves repeated, intentional aggression—physical, verbal, social, or online—that creates a power imbalance between the bully and the victim. Over time, it can lead to depression, low self-esteem, substance abuse, and even criminal behavior. Bullying varies by environment. Urban schools may see more peer aggression due to social instability, while rural schools face challenges like social isolation and unique power dynamics. Rural students face higher and more persistent bullying and repeated incidents at a higher rate than their urban peers. A growing concern is …

Redefining Rural: A Strengths-Based Framework For Enhancing Educational Policy And Practice, Dawn A. Rowe, Michele A. Schutz, Hilary E. Travers, Jon Borland

The Rural Educator

The lack of a consistent definition of “rural” in education research and policy limits equitable decision making and resource allocation for rural schools. This exploratory study used a Policy Delphi approach to elicit expert and practitioner perspectives on how rural can be conceptualized through the rural cultural wealth framework. Twenty participants across 13 states identified and refined factors shaping educational decision making in rural contexts. Results revealed strong agreement that socioeconomic status, rural culture, and community engagement are central to defining rurality. Participants’ preferred definitions emphasized familial, social, and aspirational capital, highlighting how community cohesion and resilience shape educational opportunities. …

Interview and focus group data were examined through the lens of rural community wealth to draw attention to the ways educators support their students and the resources on which they draw in their efforts. Findings illustrate that rural educators shift to providing as many services to students as possible on their school campuses; increase the capacity of staff members to address students’ mental health through targeted professional development and training; and integrate social-emotional learning …

Challenges And Opportunities In Rural Education: The Case Of La Araucanía, Chile, Katerin Arias-Ortega, Viviana Villarroel

The Rural Educator

The article reports on the challenges that rural education has been facing in La Araucanía, Chile, from the perspective of Mapuche parents. The study’s methodology was qualitative and involved Mapuche families who sent their children to rural, single-teacher schools located in an Indigenous context. The findings indicate that Mapuche mothers perceive the education that their children receive in rural schools to be of lower academic quality. Furthermore, they acknowledge that rural education receives less economic support than education in urban settings, which creates a disadvantage for Indigenous and peasant children. This disparity limits their ability to acquire the same resources …

Who Gets Closed? Twenty Years Of Access-Restricting School Closures In Arkansas, Mara C. Tieken, Christine Murray

The Rural Educator

Many states are facing dropping enrollments, budget shortfalls, and pandemic-era learning loss, and, looking to maximize efficiency and strengthen academics, they are considering district consolidation and school closure. Yet school closure is a highly contested issue, and research suggests that closure can harm students and communities. This study used discrete time survival analysis to investigate the demographic and institutional factors associated with access-restricting closures of rural schools in Arkansas from the 2003–2004 school year to the 2022–2023 school year. We looked at these closures—nearly all of them preceded by district consolidation due to under-enrollment or academic or fiscal sanction—to explore …

Updates To The Definition Of Rural, Daniel Showalter

The Rural Educator

First appearing in “Why Rural Matters 2025: People, Place, and Possibility,” this essay explains how changes to U.S. Census Bureau definitions of “urban” after the 2020 census have significantly reshaped which school districts and schools are classified as rural. These updates—such as raising population thresholds and redefining density—have led to many districts shifting classifications, with far more becoming newly rural than leaving that category. As a result, rural student counts have increased substantially, although this increase mostly reflects reclassification rather than demographic change. These shifts have important implications for funding, research, and policy decisions related to rural education.

Lesson 1. Growing Food In Winter On Rosebud Reservation? Comparing Traditional Agriculture And Hydroponics, Jaysel Magno, Genesis Barbon, Madhav P. Nepal

iLEARN Teaching Resources

Students investigate how climate influences food production by comparing traditional agriculture and hydroponic growing systems. Through discussion, visual analysis, and comparative reasoning, students examine how environmental conditions such as frost, short growing seasons, and frozen soil affect agricultural productivity in cold climate regions. Students analyze the advantages and limitations of both traditional planting and hydroponics while exploring the relationship between food sovereignty, environmental adaptation, and community sustainability. This lesson serves as the foundation for a hydroponics unit and prepares students to understand how controlled-environment agriculture can support year-round food production.
