Nonlinear plasma evolution in microgravity cannot be reliably characterized under terrestrial gravity because buoyancy-driven convection modifies or suppresses the intrinsic instability mechanisms. Consequently, the predictive design and safe operation of electromagnetically actuated plasma engineering systems require a unified theoretical framework capable of distinguishing gravity-independent behavior from phenomena that emerge only under microgravity conditions. A microgravity nonlinear plasma platform was therefore established as a multi-physics governance framework that defines the physical and mathematical conditions under which nonlinear plasma evolution becomes microgravity-dependent while providing quantitative criteria for operational stability. A dimensionless governance ratio was introduced as the principal classification metric, coupling the electromagnetic control bandwidth with the nonlinear instability growth rate. The framework was further integrated with a three-tier distributed intelligent governance of stabilized plasmas supervisory architecture, through which electromagnetic actuation, thermal-ionization energy balance, and structural boundary response are coordinated across multiple interacting physical domains. Three operating regimes were thereby defined: admissible (R > 10), marginal (1 < R ≤ 10), and runaway (R ≤ 1), each associated with prescribed electromagnetic control actions, a diagnostic latency constraint, and mandatory termination logic. An analytical microgravity threshold was derived. Recent observations from the Plasma Kristall-4 (PK-4) complex plasma facility aboard the International Space Station (ISS) were shown to be consistent with the predicted emergence of field-aligned filamentary structures and anisotropic nonlinear transport under reduced-gravity conditions. Finally, five quantitative and experimentally falsifiable predictions were formulated to establish a systematic validation pathway for future microgravity plasma experiments. Collectively, the proposed framework provides a rigorous theoretical foundation for the analysis, governance, and engineering design of high-energy-density plasma systems operating in microgravity and establishes a general methodology for the development of next-generation plasma propulsion technologies, advanced confinement architectures, and reaction-boundary control systems in coupled multi-physics environments.

The rapid expansion of autonomous Large Language Model (LLM) agents introduces critical security risks, particularly the confused deputy problem caused by orchestrator compromise or indirect prompt injection (IPI). Traditional defenses rely on in-band filtering, which fails to prevent a subverted orchestrator from bypassing security checks. We propose Intent-Execution Integrity Binding (I-EIB), a reference architecture designed to enforce complete mediation by isolating execution capabilities within a Trusted Execution Environment (TEE). By leveraging Amazon Web Services (AWS) Nitro Enclaves and Key Management Service (KMS)-based capability sealing, I-EIB ensures that sensitive API keys and session tokens remain inaccessible to the host. These credentials are only released when a TEE-based verifier confirms that the processing provenance matches a user-signed domain-specific language (DSL) policy and a predefined chain layout. We formalize the system’s security invariants and provide a structured proof sketch demonstrating how I-EIB maintains intent-execution integrity even under full host compromise. Compared with a host-mediated baseline that performs policy checking without enclave isolation or attestation-gated capability release, the proposed architecture introduces a mean additional overhead of 14.2 ms. Experimental results show a 100% detection rate for bounded step-omission attacks and a false positive rate below 0.1% after normalization. A workflow-oriented case study and computational-path analysis further indicate that the architecture is feasible for high-stakes domains such as finance and healthcare, while still carrying deployment constraints associated with TEE availability, policy precision, and wrapper management.

This paper presents a new four-node strain-based finite element (SBQ12) formulated within the framework of Reissner–Mindlin plate theory for the dynamic and stability analysis of isotropic plates resting on elastic foundations. The independent approximation of the bending and transverse shear strains in the proposed element is efficient in eliminating the shear locking and enhancing the numerical accuracy and stability for thin and thick plates. In this study, the strain-based finite element is used to investigate the free vibration and linear buckling of plates on Winkler, Pasternak and Kerr elastic foundations. The SBQ12 element is extensively validated for square and rectangular plates with different boundary conditions (all edges simply supported (SSSS), all edges clamped (CCCC), two opposite edges simply supported, two opposite edges clamped (SCSC), and two opposite edges simply supported, two opposite edges free (SFSF), etc.), thickness ratios ($a/h$ ranging from 5 to 1000), and aspect ratios. The numerical results show excellent agreement with the analytical and reference solutions, with maximum relative errors generally less than 3.5% for free vibration analyses and 4% for buckling analyses in the majority of cases tested. Particular attention is given to the influence of foundation stiffness parameters on natural frequencies and critical buckling loads. The obtained results confirm the accuracy, reliability, and computational efficiency of the proposed element. Overall, the developed SBQ12 element proves to be a robust and highly accurate tool for the analysis of isotropic plate structures resting on elastic foundations, offering a valuable contribution to computational mechanics.

The rapid growth of religious tourism has intensified the demand for supporting transport infrastructure, particularly an efficient shared parking system integrated with on-site traffic circulation and pedestrian flow management at sacred sites. This study defines the shared parking scheme as the temporal and spatial allocation of a common facility among buses (for organized pilgrim tours) and passenger cars (for individual visitors), managed by the mosque authority across distinct worship-time windows. Three research questions are addressed: (i) whether visitor groups differ in acceptable walking distance to parking; (ii) whether a digital parking guidance system is suitable across age cohorts; and (iii) how vehicle type influences parking capacity planning. A questionnaire survey was administered to 505 respondents at the Sheikh Zayed Grand Mosque in Surakarta, Indonesia. The Pearson Chi-Square Test examined associations between categorical variables; where more than 20% of cells had expected frequencies below five, Fisher's Exact Test with Monte Carlo approximation was applied, and Cramer’s V was reported as the effect-size measure. Age was significantly associated with nearly all parking-preference variables ($p <$ 0.01), with the 17–32-year cohort showing higher receptivity to digital parking information systems. Vehicle type exhibited significant associations with five of six preference variables ($p <$ 0.05) and the largest mean Cramer’s V, indicating the most consistent though not causal demographic correlate. Travel purpose was significantly associated with visiting duration ($p$ = 0.007) and acceptable walking distance ($p$ = 0.043). Findings yield four operational recommendations: (i) segregated bus and passenger-car zones with dedicated bus-reservation slots; (ii) tiered short-stay/long-stay zoning aligned with prayer-time peaks; (iii) age-differentiated wayfinding combining digital guidance and on-site human assistance; and (iv) temporary traffic control during peak worship hours.
