Preliminary Evidence Of Systems Thinking Skills In Gamelan-Based Ethnoscience Booklet-Integrated Collaborative Problem Solving, Ayu Nuryani Aprilia, Suciati Suciati

Jurnal Pendidikan Sains

Students’ systems thinking skills (STS) can be difficult to develop when science learning provides limited opportunities to connect relationships among system components with contextual phenomena. Integrating local wisdom into learning materials, such as a gamelan-based ethnoscience booklet, may provide a meaningful context for developing these skills. This study aimed to compare students’ STS performance, adjusted for pretest scores, between a class receiving Collaborative Problem Solving (CPS) instruction integrated with a gamelan-based ethnoscience booklet and a class receiving CPS instruction alone. This quantitative study employed a pretest–posttest control group design with class-level random allocation of treatment and involved 56 Grade VIII …

Technical Specification: Solid-State Planar Harmonic Confinement Core, Christopher L. Eckes

Defensive Publications Series

This specification details the structural implementation parameters for replacing the high-inductance, cryogenically cooled magnetic confinement loops of traditional thermonuclear architectures with an ambient-temperature, solid-state Harmonic Wave Confinement Core.

By compiling non-linear fluid solutions of the three-dimensional Navier-Stokes regularity framework (SPEC-091)directly into specialized Gallium Nitride (GaN) interdigital transceiver arrays, this architecture utilizes high-frequency spatial-harmonic pressure fields to isolate high-energy plasma within a stable Gor'kov potential well.

We address historical limitations in structural boundary containment by integrating embedded 3D Photoemission Orbital Tomography (3D-POT) real-time wavefront feedback loops with custom asymmetric, asynchronous Application-Specific Integrated Circuit (ASIC) hardware routing controllers and explicit covalent valence-shell …

The Currency That Cannot Be Spent Alone: Co-Presence-Gated Redemption And The Chronicle↔Treasury Unification Circuit — Time-Banking Credits Redeemable Only At A Synchronous, Mutually Attested Meeting Of Both Parties, Thon Ly

Defensive Publications Series

In the disclosed time-banking system, a credit (a pledged hour, issued as thanks between two named persons) has one redemption form: a synchronous meeting both parties attend, in person or by live audio or video call, with shared attention face to face or side by side on a shared task. Recorded messages may carry an invitation but cannot redeem a credit, so absentee service cannot be expressed. Both parties confirm delivery, corroborated by device proximity or the live session; an in-person exchange of public-key fingerprints, as at a key-signing party, is described as one candidate corroboration path that may admit …

Before Launch: A Design-Stage Systems Engineering Doctrine For Autonomous Artificial Intelligence, Volodymyr Kotegov

Defensive Publications Series

This study presents a systems-engineering framework for the development, verification, qualification, and eventual authorization of increasingly capable autonomous AI systems. The doctrine addresses a central engineering problem: how to permit capability growth without allowing assurance, evidence, or authority mechanisms to become obsolete as the system changes.

The framework separates design specification from empirical evidence and distinguishes qualification, authorization, and runtime states. It establishes an assurance chain linking requirements, claims, verification activities, evidence, status transitions, and authority consequences. Core mechanisms include Verifiable Trust, Graduated Verifiable Autonomy Architecture, Bounded-Risk Agility Architecture, local multi-scale control, preserved behavioral baselines, capability-jump controls, mechanistic verification, independent …

The Game That Graduates You: A Witness Api For Children's Games And Education — A Permission-Scoped Game Api Without Payment Authority, Parental-Consent Family Content As Curriculum, And Course Completion As The Success Metric For Educational Apps, Thon Ly

Defensive Publications Series

We describe a permission-scoped third-party API architecture for children's educational games and learning apps. A game client may propose real-world tasks to a child, styled in the game's fiction from real household context, and may receive a minimal completion notification when a family member witnesses the act; it can never hold payment, transfer, balance or reward-issuing scopes, so task completion issues no currency or points, and any reward is a human-initiated acknowledgment through the family's own ledger app. Parents approve which apps may propose to each child, revocably and default-off. With per-item parental consent and on-device processing, the family's own …

The Principle Of A Unified Field Invariance In Astrophysics, Peter Stevenson

Defensive Publications Series

This paper presents a fresh approach to  cosmology in that all aspects are different representations of the same State. This identifies a non-linear, non-transactional framework for topological field mechanics, introducing a universal invariant state descriptor, S. We challenge the traditional compartmentalization of fluid dynamics, gravitation, and thermodynamics into independent subgroups, demonstrating that they are localized, downstream resultant effects of a single field configuration.

Fleet-Based Autonomous Remediation Using A Vectorized State-Action Map, Jason Schissel, Piotr Milian, Nicholaus Jackson

Defensive Publications Series

Computing devices in offline or low-trust states may be inaccessible to remote diagnostic and support tools, which can hinder the remediation of operational issues that cause a disconnected state. On-device agents may represent an anomalous system condition as a problem state vector and a corresponding fix as a solution action vector. These vector pairs can be transmitted from a fleet of devices, such as smartphones, laptops, or internet of things devices, to a central repository. A repository can aggregate the vector pairs, apply analytical techniques such as clustering to identify common failure patterns, and build a global state-action map representing …

Servingness In Solidarity: How Filipina/X/O American Student Organizations Cultivate Belonging, Clarissa Mae Lico Calimbas

Dissertations

Filipina/x/o American college students represent one of the largest Asian ethnic subgroups in the United States, yet their educational experiences remain underexamined within institutional research and higher education scholarship. Aggregated under the broader Asian American category, Filipina/x/o American students are rendered invisible by data practices that obscure the distinct colonial histories, socioeconomic realities, and identity negotiations. This qualitative study examined how Filipina/x/o American students at Pacific State University (PSU) describe their involvement in Filipina/x/o American Student Organizations (FASOs) and how that involvement shapes their sense of belonging, cultural identity development, and academic persistence. Guided by a critical race phenomenological framework …

Results revealed statistically significant differences at the 0.01 level between pretest and posttest means on the observation card …

Generalized Apostol-Bernoulli Functions And The Evaluation Of Character Sums, Brad Isaacson

Publications and Research

We introduce two types of generalized Apostol–Bernoulli functions attached to Dirichlet characters and express them by generalized Apostol–Bernoulli numbers. As a corollary, we obtain formulas expressing two families of character sums by generalized Apostol–Bernoulli numbers. These sums are twisted generalizations of sums introduced and studied by Arakawa, Berndt, Ibukiyama, Kaneko, Kim, Ramanujan, and Zaharescu in the context of modular forms and theta function identities.

Efficient Acidic H2O2 Electrosynthesis Over Co Atoms Anchored On Nitrogen-Doped Hierarchical Porous Carbon, Xiao Huang, Zi-Hao Zhan, Hao-Xu Niu, Guan-Yu Luo, Jin-Tao Huang, Bo-Xuan Jin, De-Li Wang

Journal of Electrochemistry

The two-electron oxygen reduction reaction (2e⁻ ORR) presents a promising route for the on-site production of hydrogen peroxide (H₂O₂), offering a green alternative to energy-consuming anthraquinone process. However, the high selectivity toward the competing 4e⁻ ORR over the desired 2e⁻ pathway leads to low Faradaic efficiency for H₂O₂, posing a critical challenge in catalyst design. In this work, a nitrogen-doped hollow hierarchical porous carbon with anchored Co atoms (CoN/HPC) was constructed for high-performance H₂O₂ production. The as-prepared Co-N/HPC catalyst showed excellent 2e⁻ ORR performance, achieving …

Engineering Small-Sized Cations With Strong Solvation For High-Voltage Supercapacitors, Tong Huo, Pan Liu, Hao Chen, Peng Zhang, Zhen-Lei Chen, Guo-Fu Sun, Zhi-Qiang Shi, Jing Wang

Journal of Electrochemistry

Supercapacitors (SCs) have attracted much attention in the field of energy storage due to their high power density and long cycle life. However, their relatively low energy density limits their application in a wider range of fields. Methods to increase energy density include enhancing specific capacitance and extending operating voltage window. Herein, we report a novel electrolyte salt, tetramethylammonium bis(fluorosulfonyl)imide (TMA-FSI), the resulting electrolyte formed with propylene carbonate (PC), designated as TMF, exhibited a wide electrochemical stability window (ESW) of 5.09 V. On the one hand, we found that the small size of TMA⁺ enables it to enter the …

Kurosu, Abhishek Chatterjee, Joshua B. Fisher, Maggie Johnson, Le Kuai, Kanishka Mallick, Nicholas Parazoo, Benjamin Wiebe, Kerry Cawse-Nicholson

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Terrestrial ecosystem regulation of carbon and water fluxes is critical for constraining climate–biosphere feedbacks but remains poorly quantified across space and time. Here, we evaluate whether co-located observations from NASA's Orbiting Carbon Observatory-3 (OCO-3) and the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) can reproduce ecosystem water use efficiency (WUE) dynamics observed at FLUXNET sites across temporal scales, vegetation types, climates, and drought conditions. We created the ECOCO3 data set, which harmonizes OCO-3 and ECOSTRESS observations in space and time. ECOCO3 captures broad seasonal and diurnal carbon and water flux patterns including midday drought responses. Sampling sensitivity analysis …

Dense Platinum Nanoparticles Confined In Mn-N-C Nanocages For Robust Heavy-Duty Pemfcs, Lei Zhao, Zhen-Min Cao, Jia-Yu Zuo, Ming-Liang Yang, Hong-Yan Qiao, Jun-Song Chen, Rui Wu

Journal of Electrochemistry

High-loading Pt cathodes are essential for heavy-duty proton exchange membrane fuel cells but suffer from a critical tradeoff between ionomer sulfonate poisoning and nanoparticle instability. Herein, we report a spatial confinement strategy to encapsulate dense Pt nanoparticles (~51.8 wt%) within Mn/N-co-doped mesoporous carbon nanocages (denoted as Pt-MnNC). This architecture excludes bulky ionomers to create an ionomer-shielded environment against sulfonate poisoning, while Mn-N_x-mediated strong metal-support interactions anchor the Pt nanoparticles to prevent agglomeration and further boost durability. In the 5 × 5 cm² membrane electrode assembly tests, the Pt-MnNC catalyst delivers an exceptional power density of 1.26 W·cm …
