Chaos-based image ciphers may exhibit favorable statistical metrics while retaining a recoverable algebraic structure. We analyze the modified one-time-pad image cryptosystem of Stoycheva et al., which combines static, Chua-system-derived, and neural masks with channel-wise shuff...

An adaptively weighted targetless rotation axis calibration method based on angle prior
In rotary-stage structured-light 3D measurement systems, the calibration accuracy of the rotation axis determines the registration quality of multi-view point clouds. Among existing calibration methods, traditional target-based approaches are susceptible to the defocusing interfe...

Frost risk, phenology and adaptation in cold-climate viticultural systems
CONTEXT Late spring frost remains a major climatic constraint in cold- and cool-climate viticulture, where grapevine development is strongly shaped by seasonal temperature variability. Although climatic warming is often expected to reduce frost hazard through declining frost freq...

Accurate estimation of the coefficient of variation (CV) is essential for assessing the variability of environmental pollutants such as fine particulate matter (PM2.5). This study proposes a Wald transformation-based (Wald-TB) confidence interval for the CV of Gamma-distributed d...

Abstract Objective Brine shrimp Artemia spp. nauplii are a widely used first feed in ornamental aquaculture due to their digestibility, adequate nutritional profile, and ability to elicit feeding behavior from larval fish. Issues with variable cost and nutritional consistency, ho...

Environmental changes downstream of dams after sediment sluicing in the Mimikawa River system
Triggered by the extensive flood damage in the Mimikawa River system due to Typhoon Nabi in 2005, Miyazaki Prefecture, the river administrator, played a leading role in establishing the Integrated Sediment Flow Management Plan. As part of this scheme, Kyushu Electric Power Co., I...

Mechanistic versus descriptive interpretation of brain activity pattern reconstruction
The geometric eigenmodes, derived from the shape of the cortical surface, have been suggested as a better model for explaining brain function due to their high accuracy in reconstructing patterns of both spontaneous and stimulus-evoked brain activity patterns captured by function...

Artificial Neural Networks for RF Passive-Device Modeling and Design: A Review
Artificial neural networks (ANNs) offer efficient surrogates for radio-frequency (RF) passive-device modeling and design, but prediction accuracy alone does not establish their engineering reliability. This review examines four overlapping analytical perspectives: data generation...

Patient perceptions of emergency department versus GP visits and of GPFirst: a qualitative study
Abstract Introduction: Overcrowding in emergency departments (EDs) has long been a concern, contributing to adverse outcomes. To address inappropriate attendances, Changi General Hospital (CGH) introduced GPFirst, a programme that encourages patients with mild conditions to visit...

Quantum Coherence in Posner Molecules: Refuting Symmetry Assumptions — E8 Intelligence Research
FINDING: Posner molecule (Ca₉(PO₄)₆) quantum coherence evidence is contested; the arXiv paper explicitly refutes symmetric dynamical assumptions, while popular claims of "brain quantum effects" remain unverified. | MATH: Posner molecule stoichiometry: Ca₉(PO₄)₆ — 9 calcium ions,...

Electron transport chain: a crucial target of luteolin in combating Trueperella pyogenes
ABSTRACT Trueperella pyogenes is an opportunistic pathogen capable of causing infections in both domestic and wild animals. Furthermore, the dissemination of resistance genes has resulted in varying degrees of antimicrobial resistance among T. pyogenes isolates. Therefore, it is...

The astrophysical 21-cm hyperfine line of hydrogen is traditionally described as the energy splitting arising from the continuous magnetic dipole-dipole interaction between the electron and proton spins. In this paper, we expose a fundamental methodological trap in digital physic...

Facilitating Quality Feedback Practices for Teacher Educators: An Action Research Study
The student teaching practicum is widely considered the most important experience for pre-service teachers, providing a key opportunity for high-quality feedback to support instructional growth. Cooperating teachers and university supervisors (faculty responsible for observing an...

Rethinking transformative tourism: transcendence as the reconfiguration of self-world relations
Purpose Transformative tourism research has expanded rapidly, yet “transformation” remains conceptually diffuse and often conflates different depths of experiential change. This article reassesses how transformation has been theorized and advances a transcendent account of higher...
- Society & EconomicsOpen access
The mathematical constants π and e are irrational and transcendental numbers whose infinite, non-repeating decimal expansions mimic randomness. This study investigates potential underlying structures within these sequences by treating their digits as discrete time-series signals....

Governing Solar Geoengineering at Planetary Scale: Pipe Dream or Possibility?
Solar geoengineering is being suggested by some scientists as a partial solution to the climate crisis. However, these hypothetical technologies to reflect parts of incoming sunlight back out into space pose significant governance challenges, due to their ecological risks, planet...
