Comparison Of Umbral Dot Physical Properties In Developed And Undeveloped Sunspots, Muhammed Ali̇ Çalişir, Ali̇ Kilçik, Vasyl Yurchyshyn

Turkish Journal of Physics

Sunspots are cool regions where the magnetic field is significantly stronger than in the surrounding photosphere, and their darkest central regions are known as the umbra. Umbral dots (UDs) are small, bright features within the umbra that represent convective motions partially suppressed by strong magnetic fields. In this study, high-resolution images from the Goode Solar Telescope (GST) at Big Bear Solar Observatory (BBSO) were used to analyze four sunspots at different evolutionary stages, including two developed and two undeveloped sunspots. The physical properties of UDs, including brightness, diameter, eccentricity, lifetime, and dynamic velocity, were measured and compared across these sunspots …

Stress–Strain Behavior Of The High-Entropy Cantor Alloy Crmnfeconi Using A Deep Neural Network Potential, Nguyen Le Hoai Phuong, Le Huu Nghia, Huynh Khanh Van, Vo Khuong Dien, Nguyen Thanh Tien

Turkish Journal of Physics

Machine learning interatomic potentials (MLIPs) provide an efficient approach to large-scale molecular dynamics simulations of high-entropy alloys. In this work, an MLIP trained on AIMD data was developed for the CrMnFeCoNi Cantor alloy and validated against DFT calculations. In addition, we compared MLIP results with those obtained using the classical modified embedded atom method (MEAM)-based interatomic potential for the CrMnFeCoNi Cantor alloy. The model achieved energy and force RMSEs of 7.39 x 10-6 meV/atom and 4.46 x 10-3 eV/A, respectively. Tensile simulations demonstrated that the MLIP accurately reproduced the stress–strain response, elastic constants, and deformation mechanisms observed in DFT calculations. …

Spacer-Mediated Gold Nanocube Arrays For Edge-Localized Excitonic Enhancement In Monolayer Mos2​, Abdullah Efe Yildiz, Emre Ozan Polat

Turkish Journal of Physics

Plasmonic nanostructures offer an effective route for enhancing light-matter interaction in atomically thin semiconductors, whose optical response is intrinsically limited by their subnanometer active thickness. Here, we numerically investigate excitonic enhancement in monolayer (ML) Molybdenum Disulfide (MoS2) coupled to size-tuned gold (Au) nanocube arrays separated by thin aluminum oxide (Al2O3) and hexagonal boron nitride (h-BN) spacer layers. By varying the nanocube side length, the localized surface plasmon resonance is tuned across the visible spectral range to modulate the A- and B-excitonic transitions of monolayer MoS2.We show that the nanocube-size-dependent spectral redshift can be further controlled through the spacer material and …

Theoretical Construction Of Light Hexaquarks And Their Substantiation By Seven-Dimensional Representation Of Su(2) Group, Mayank Joshi, Shuchi Bisht, Navjot Hothi, Manish Bisht

Turkish Journal of Physics

This manuscript presents a theoretical approach to constructing light hexaquarks using up and down quarks. These light exotic hexaquarks are shown to exhibit a seven-dimensional representation of the SU(2) isospin group. Additionally, the isospin septuplet is developed along with the quintet, triplet, and singlet representations for these light exotic hexaquarks. These particles are essentially mesonic in nature and also satisfy the requirements of the Kronecker product. Furthermore, the physical characteristics and weights of the respective states are intrinsically provided for these light hexaquarks.

Ai Tutor, Online Course, Or Both? A Randomized Experimental Pilot Study For Evaluation Capacity Building, Lendel Kade Narine, John M. Diaz

Extension Research

Extension lacks literature comparing standalone generative artificial intelligence (AI) with structured professional development for capacity building. Guided by Social Cognitive Theory and Cognitive Load Theory, this study evaluated the effects of an asynchronous online course and a custom AI tutor on evaluation knowledge and self-efficacy among Cooperative Extension professionals. We conducted a randomized 2 × 2 factorial pilot study crossing access to an evaluation certificate course with access to a custom Generative Pre-trained Transformer (GPT). Of 144 registrants, 78 provided matched pre- and post-test data, with attrition differing across conditions. Data were analyzed using a three-way mixed factorial ANOVA. Course …

Design Implications For Teacher-Configurable Generative Ai Writing Tools: A Participatory Design Study With Storybot, Ariel Han, Shenshen Han, Zhenyao Cai, Joey Huang, Franceli Cibrian, Kylie Peppler

Engineering Faculty Articles and Research

As generative AI (GenAI) tools become accessible, their integration into K–12 writing presents opportunities and challenges. This study partnered with 21 primary school teachers in a participatory co-design process to develop StoryBot, a teacher-configurable GenAI story-authoring platform. Teachers identified instructional needs and learning outcomes that informed system features, including genre-specific writing scaffolds, configurable prompts, and constraints on full-text generation to preserve student voice. The platform positions educators as co-designers of AI behavior rather than passive users. We conducted a pilot writing workshop with 13 youth (ages 8–12) and a focus group with six educators to examine how the platform influenced …

Navigating Systemic Neglect: Educator Perspectives On Supporting Central American Unaccompanied Minors In California Public Schools, Stephany Cuevas, Martha C. Franco

Education Faculty Articles and Research

This qualitative study examines how educators in California public schools conceptualize and respond to the needs of Central American unaccompanied minors. Using a sociohistorical trauma-reducing framework, we analyze interviews with 29 teachers, counselors, social workers, and afterschool providers. Findings highlight structural barriers to resources and identification, academic and linguistic challenges shaped by interrupted schooling, unmet mental health and socioemotional needs, and the burden educators assume as advocates within trauma-producing systems. Despite employing relational, justice-oriented practices, educators work within conditions that undermine sustainability, underscoring the need for trauma-reducing, equity-driven reforms.

In-Home Free-Living Gait Monitoring Using A Single Lumbar Imu Reveals Nonlinear Complexity Changes During Intensive Stroke Rehabilitation, Rahul Soangra, Susan V. Duff, Alison Mckenzie

Physical Therapy Faculty Articles and Research

Conventional clinical assessments of stroke rehabilitation are limited to supervised environments and fail to capture continuous real-world motor behavior. This proof-of-concept pilot study (case series, n = 3) evaluated the feasibility and longitudinal sensitivity of wearable IMU-derived digital biomarkers of three individuals with chronic stroke across Chapman University’s Stroke Boot Camp (SBC), a two-week intensive interdisciplinary rehabilitation program. A lower-back-mounted DynaPort McRoberts IMU provided continuous multi-day free-living monitoring across five sessions that spanned one week pre-intervention through to three months post-intervention. A validated Python-based pipeline implemented Mobilise-D gait sequence detection, wavelet-based heel strike and toe-off identification, and extraction of linear …

Representation Of Beauty: Gendered Discourses In Czech And Indonesian Advertisements, Indah Kurnia Herliani, Nurenzia Yannuar, Yusnita Febrianti, Ahmad Faizuddin

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

Beauty advertising is a public multimodal site in which gendered beauty ideals are made visible and linked to consumption. This study examines how beauty is constructed in the linguistic landscape (LL) of public advertisements in two localized urban settings: Olomouc, the Czech Republic, and Malang, Indonesia. We combine LL as the spatial and sociolinguistic framework, multimodal analysis through Cheong's (2004) Generic Structure Potential (GSP), and Feminist Critical Discourse Analysis (FCDA), operationalized through Fairclough's (1992) three-dimensional model. Rather than treating the two sites as representative of their countries or regions, we use them as comparative case studies to examine how similar …

Childcare Teachers’ Perspectives On The Sufficiency Of Their Safety Training, Mary Hipp

Walden Dissertations and Doctoral Studies

Young children are still developing, which makes them vulnerable and puts them at risk for safety incidents. The problem that was addressed through this study was that in many childcare centers’ children are unsafe because incidents that affect children’s physical safety occur frequently. Guided by Noe’s elements of effective training, the purpose of this basic qualitative study was to explore childcare teachers’ perspectives on the sufficiency of training they have received to respond to incidents that affect children’s physical safety, to prevent future incidents from happening, and the factors they believe would increase the effectiveness of such training. Data were …

A Sneak Peek Into Prehistory: Curating An Interactive Fossil Display To Spark Interest In The Ua Little Rock Natural History Museum, Syd Joheim, Rene Shroat-Lewis

Research and Creative Works Expo

Arkansas does not currently have a dedicated natural history museum, creating a unique opportunity for UA Little Rock following the recent donation of an expansive fossil collection. In response, the university established a natural history museum initiative intended to benefit both the campus community and the broader public across Arkansas. This initiative provides accessible resources for learning about natural science, evolution, and the state’s prehistoric past, areas that are often underrepresented in informal science education. It also serves as a platform for outreach, student engagement, and undergraduate research, strengthening UA Little Rock’s role in science education, workforce development, and community …

"The Effect Was The Same, But Not For The Eye." From Playability To Augenmusik In Beethoven’S Arrangement Of His Grande Fugue Op. 133/134, Elisa Novara

The Beethoven Journal

Beethoven’s four-hands piano transcription of the Grande Fugue Op. 134 is different from any other arrangement he ever made: firstly, it is given an opus number, which is something that conventional Klavierauszüge usually do not have; secondly, it has a dedication, namely to Beethoven’s patron and pupil the Archduke Rudolf. Third, it is notoriously so difficult to play that it barely fulfils the primary function of four-hands piano transcriptions in the 19th century, i.e. a more easily accessible performance medium, which would have resulted in a better circulation of the work.

A more conventional transcription of Op. 133 might have …

"Wondrous Emanations Of A Transcendently Transfigured Sublimity And Profundity": The Reception Of Beethoven's Last Three Piano Sonatas In The Nineteenth And Early Twentieth Centuries, Nicholas S. Kennedy

The Beethoven Journal

Ludwig van Beethoven’s last three piano sonatas, Opp. 109, 110, and 111, have captured the imaginations of critics from the nineteenth century to the present. As “late” works penned towards the end of the composer’s life, these sonatas have often been read as infused with existential or transcendental meaning, frequently aligned with Beethoven’s own experiences. Reception studies have identified broader tropes of autobiographical explanation and poetic analogy as applied to these works by early critics; however, these studies frequently stop short of identifying more specific patterns in the images employed to describe the sonatas. Focusing on mainly German literature from …

Beethoven, Caspar Peucer’S Commentarius, And Enchanted Nature, Nicholas Chong

The Beethoven Journal

The posthumous inventory of Beethoven’s library includes a late Renaissance treatise by Caspar Peucer (1525–1602) entitled Commentarius de præcipuis generibus divinationum (Commentary on the main types of divination). Peucer’s text is concerned mainly with methods of predicting the future through such practices as magic, astrology, and the reading of oracles. Neither Peucer nor his treatise is mentioned in any other source associated with Beethoven. The composer also had a limited knowledge of Latin and his copy of Peucer’s text was more than two centuries old.

Previous scholarship has not explored Beethoven’s ownership of this book in any detail, except to …

Offlinesi™: Island Mode For An Organization's Ai Systems, With Governance That Tightens With Time Offline And Staged Reopening, Edward D. H. Wang

Defensive Publications Series

This disclosure describes an island mode for the AI systems of an organization or a single device. All traffic between the organization's governed AI systems and the outside world passes through one governed gate. When the gate closes, whether for maintenance, on detection of an attack, on loss of outside connectivity, or by order of an authorized person, the organization's own AI compute, governed data custody and personal AI devices keep serving each other inside, under locally held, signed policies and credentials with declared validity periods. While the island lasts, governance tightens as a declared function of time offline: the …

Si Regulator™: Independent Second Opinion For Critical Actions Of Ai Systems, Tied To A Governor Ladder And Verified Model Lineage, Edward D. H. Wang

Defensive Publications Series

This disclosure describes a runtime rule for AI systems under which no critical action is taken on the judgment of a single AI model. Before a critical action is admitted, an independent verifier reviews it. The verifier is one of: a second model whose independence from the first is proven by its recorded lineage (a different developer, base model or training history, as shown in a signed model birth certificate); a deterministic rule checker; or a person. The verifier runs on separate compute, receives the proposed action and its context but not the first model's reasoning, and cannot be addressed …

Radio-Agnostic Modular Radio Architecture For Wireless Audio Equipment: The Modem On A Pluggable, Self-Identifying Radio Module Fed Framed, Already-Encrypted Blocks, One Radio Interface With A Capability Descriptor, Software Fec Only Where The Radio Lacks It, Capacity Scaled To The Modules Counted At Boot, And A Second Radio Used By Role, Anonymous

Defensive Publications Series

The modem lives on the radio module, not on the host. The host-to-module interface carries framed, already-encrypted audio blocks (and, for a module without error correction, already error-protected ones). A narrowband module is a transceiver run in synchronous direct mode: the host streams the framed bits to its data and clock pins. A wideband module is an I/Q transceiver front end plus an FPGA running an OFDM/TDMA modem, entirely self-contained: the host streams the same framed blocks and the module’s FPGA places them on the air. The host never sees I/Q, OFDM symbols or modem timing beyond a block period. …

Technical Specification: Spec-207-Core Title: Solid-State Acoustofluidic Replicator Box And Closed-Loop Molecular Recycling Appliance For Extraterrestrial Mechanical Counter-Pressure Apparel Suites, Christopher L. Eckes

Defensive Publications Series

This specification defines the structural criteria and design layout parameters for an autonomous, on-site manufacturing and recycling node designed to operate under extraterrestrial surface conditions. By combining high-frequency Gallium Nitride (GaN) concentric transducer arrays for non-thermal mechanochemical chain scission with acoustophoretic multi-nozzle print heads, the engine isolates ancestral human priority art, neutralizes corporate enclosure traps, and achieves an airtight, closed-loop material recycling perimeter for life-critical space colonization architectures.

Spec-206-Core: Integrated Metamaterial Spacesuit Mesh And Solid-State Acoustofluidic Replicator Appliance For Extraterrestrial Mechanical Counter-Pressure Life Support, Christopher L. Eckes

Defensive Publications Series

This specification establishes the mathematical and structural criteria for an integrated, closed-loop extraterrestrial apparel manufacturing and recycling framework. The system defines a monolithic 3D-printed elastomeric spacesuit mesh that applies uniform mechanical counter-pressure (MCP) directly to human anatomy, alongside an on-site acoustofluidic replicator box configured to recycle worn suits back into pristine base monomers via non-thermal mechanochemical chain scission. This integrated, multi-tier system eliminates traditional manual cut-and-sew textile multi-layer manufacturing bottlenecks, suppresses volatile outgassing in high-vacuum space environments, and establishes an irreversible public-domain defensive barrier against the proprietary privatization and corporate enclosure of life-critical planetary colonization technologies.

Si Regulator™: One Governance Point For An Ai System's Actions And Its Automated Access To Data And Resources, Edward D. H. Wang

Defensive Publications Series

This disclosure describes a single governance point through which an AI system must pass both the actions it takes on the world and its automated access to data and resources. Actions include physical commands, tool and API calls that change state, transactions and messages sent. Access includes reading or querying data, retrieving documents, obtaining credentials, and using compute, storage or network capacity. Every such request is classified by its effect rather than by the channel it arrives on, checked against one policy, one identity and one current governor level, and either admitted, narrowed, held for human approval or refused. Access …

Si Regulator™: Runtime Intervention On Ai Controlled Machines That Throttles Planning And Never Stabilizing Control, Edward D. H. Wang

Defensive Publications Series

This disclosure describes a runtime regulator for machines whose high-level behaviour is chosen by an AI model (robots, drones, vehicles, industrial arms). The regulator divides the machine's control into a planning layer, which chooses goals and actions, and a stabilizing layer, which keeps the body physically safe (balance, attitude, braking, thermal and power limits). When the regulator detects that the machine is leaving its declared operating envelope, it intervenes in graded steps that act on the planning layer only: it narrows the goal set, slows the rate of new actions, restricts the action vocabulary, requires human approval and, at the …

Si Reset™: Out-Of-Band Reset Of Ai Systems With Triggers Independent Of The Runtime Governor And Separate Safety And Audit Heartbeats, Edward D. H. Wang

Defensive Publications Series

A system and method for stopping and safely restarting an AI system through a reset mechanism that is independent of the system's runtime governor. A reset controller on a separate safety plane, with its own power and its own communication channel, acts on its own set of triggers: readings from safety-grade sensors, an operator's emergency stop, an escalation request from the governor, and the loss, fault or tampering of the governor itself. Two heartbeats are kept separate: a safety heartbeat, local, out-of-band and with a hard deadline, whose loss engages fail-safe behavior; and an audit heartbeat to a ledger over …

Defensive Publications Series

This paper presents a decentralized, low-CapEx alternative to the energy-intensive Haber-Bosch process by introducing a novel framework for ambient-temperature NPK synthesis and carbon-negative ceramic vitrification. It utilizes green processes that provide potential Carbon Tax benefits, existing raw materials that are currently considered waste, and biological conversions. The Executive Summary is more comprehensive.

Solid Ground: A Fractal, Governed Shared-Memory Methodology For People And Machines, Given To The Commons, Shannon J. Dobbs

Defensive Publications Series

A coordination methodology lets people and machine agents work together through legible shared records without anyone giving up control of their own. Its central element is an interlock: a single per-record access rule, evaluated by the data store, that at once withholds a participant's own context from any authority, governs the records a goal-directed learning loop reads and writes, and cannot be altered by anything a machine agent reads. The participant holds a user-held skill file, drawn out by an AI interview, that composes with an optional institution's own skill file and with the AI; the participant decides, per recipient, …
