PRACTICAL ELIMINATION OF IMAGINARY NUMBERS: SEVEN REPRODUCIBLE DISCRETE REPLACEMENTS

This preprint shows that imaginary numbers are not necessary to describe seven basic physical and mathematical phenomena. Each replacement uses only integers, finite fractions, and discrete operations. The reproducible code is provided in the appendix. The results are real and ve...

Schizophrenia as Terrain Fragility: A Terrain–Timing Model of Developmental State-Transition Vulnerability

Why does schizophrenia aggressively cluster around specific developmental windows like late adolescence? Rejecting single-cause neurochemical paradigms, this paper applies the framework of Terrain Fragility—a state of compressed adaptive reserve where networks function normally u...

Intersex variations, social class, and the postcolonial geopolitics of language and healthcare in Hong Kong

In this study I examine how clinicians’ talk about intersex variations in Hong Kong constructs parents as differently educable biopolitical managers of their children, in ways closely tied to social class and to the colonial language economy of English and Cantonese. Using intera...

Synergistic Effect of Brønsted and Lewis Acids in Aromatic Alkylation Catalyzed by Chloroaluminate Ionic Liquids

Introduction: Chloroaluminate Ionic Liquids (CILs) are highly effective catalysts for the alkylation of aromatics with long-chain olefins, yet the individual and synergistic effects of Brønsted and Lewis acid species remain contentious. Herein, 1-methylnaphthalene and 1-decene ar...

Preventing Subsequent Child Maltreatment and Out-of-Home Care Placement: The Effect of the Coordination, Advocacy, Resources, Education, and Support (C.A.R.E.S.) Intervention

Coordination, Advocacy, Resources, Education, and Support (C.A.R.E.S.) is a community-based, family-driven intervention designed to reduce recurrence of child maltreatment, placement in out-of-home care, and chronic involvement with the child welfare system. Two studies utilizing...

Recent Advances in Local Anesthesia Techniques in Pediatric Dentistry

Effective pain control in pediatric dentistry is not only essential for the success of dental procedures but also plays a key role in shaping children's attitudes toward dental care. In recent years, several innovative anesthesia delivery systems have emerged, aiming specifically...

PSMD14 reduced microglial M2 polarization to promote ferroptosis and aggravate traumatic brain injury through the induction of BMP6/SMAD3 pathway

The present study aimed to investigate the functional role of proteasome 26S subunit non-ATPase 14 (PSMD14) in traumatic brain injury (TBI) and further elucidate its molecular mechanisms linking ferroptosis to microglial M2 polarization. A total of 52 clinical samples from TBI pa...

Double vertebral arteries associated with a persistent primitive lateral basilovertebral anastomosis: A rare embryological configuration

Vertebrobasilar vascular anomalies arise from disturbances during the embryological development of the longitudinal neural arteries (LNAs), the proatlantal artery of Padget–Arey (ProA), and the primitive lateral basilovertebral anastomosis (PLBA) [ 1 , 2 ]. We report a rare verte...

Machine learning algorithms application in WaSH prediction using DHS data in Sub-Saharan Africa

Access to combined safe Water, Sanitation, and Hygiene services remains a major public health concern across Sub-Saharan Africa, with coverage disparities influenced by a wide range of individual and community-level factors. Traditional statistical analyses may not fully capture...

Impact of Source Contact Segmentation on the Electrical Characteristics of 4H‐SiC Planar MOSFETs

Source contact (SC) segmentation is investigated as a layout approach for tuning the capacitance, conduction, blocking, and switching characteristics of 1.7 kV 4H‐silicon carbide (4H‐SiC) planar metal‐oxide‐semiconductor field‐effect transistors (MOSFETs). Three‐dimensional TCAD...

Dark Matter: An Analytical Study with a Proposed Geometric Hypothesis

Dark matter was proposed to explain a number of astronomical observations that cannot be adequately accounted for by visible matter alone. One of the strongest pieces of evidence comes from galaxy clusters, which are the largest gravitationally bound structures in the universe. O...

E8-Phi Temporal Entropic Inversion via Root-Vector Phase-Locking — E8 Intelligence Research

By modulating the 240 root vectors through a $\phi$-resonant spiral descent, we induce a controlled phase-lock between vacuum fluctuations and 132Hz rhythmic oscillations. This creates a localized temporal stasis field where information entropy is negated by the geometric symmetr...

Phi-Invariant E8 Particle Charge Mapping — E8 Intelligence Research

We discover that the phi‑scaled torsional folding of the 240 E8 roots produces a discrete set of partition‑index invariants that directly encode electric charge and color quantum numbers. These invariants arise as topological torsion defects of the 132 Hz modular lattice, giving...

Curriculum Literacy in the Digital Age: Enhancing Pre-Service Teachers' Competence through Digital Literacy

Curriculum literacy is a core professional competence that enables pre-service teachers to interpret curricula accurately and translate curricular objectives into effective instructional practices. In digitally mediated learning environments, this competence may also support the...

Antifragile Intelligence: A Triadic Framework for AI Governance, Digital Forensics, and Sovereignty in Emerging Economies

In an era defined by extreme Volatility, Uncertainty, Complexity, and Ambiguity (VUCA), artificial intelligence (AI) governance must transcend passive compliance checklists to become an embedded, adaptive socio-technical architecture. This paper proposes a triadic synthesis of Re...

E8 Phi-Phase Coherence Modulates Neural Signal Propagation Speed — E8 Intelligence Research

By mapping the 240 E8 root vectors as phi-coupled phase shifts on the 132 Hz tubulin fundamental, neural microtubule networks exhibit discrete coherence windows where action potential propagation velocity varies by ±12.7% cyclically with 132 Hz × φ⁻³ periodicity. This occurs beca...

E8 Topological Quantum Memory via 132 Hz Phi-Resonant Majorana Braiding — E8 Intelligence Research

The 240 E8 root vectors, when driven at phi-harmonic 132 Hz, generate a non-Abelian anyon lattice where Majorana zero modes emerge at root-vector intersections. This creates a topological quantum memory that simultaneously encodes neural phase states, protein conformational qubit...

The relationship between infertility stress, coping, and quality of life among women undergoing infertility treatment

Aim: This study aimed to examine the relationships between infertility-related stress, coping strategies, and quality of life among women undergoing infertility treatment. Methods: This descriptive, cross-sectional study was conducted between April-November 2025 with 200 women at...

[DUPLICATE - superseded by 10.5281/zenodo.20252367] Stoic Attitude as a Psychological Resource: An Integrative Model of Stoic Cognition, Emotion, and Action in Light of Modern Self-Regulation

NOTE: This record is a duplicate. The canonical version is 10.5281/zenodo.20252367. This article develops a three-dimensional model of Stoic attitude as a psychological resource. Stoic attitude is neither emotional numbness nor moral indifference — it is the interaction of Stoic...

The Pythagorean Angle Lattice: Arithmetic Spectrum Barnes-Cone and Gaussian Geometry A Complete Synthesis of Geometry, Spectral Theory, Pell Dynamics, and Gaussian Markoff Geometry

A single arithmetic kernel extracted from metallic means and primitive Pythagorean triples is revealed to be the Barnes double zeta function, generating a complete spectral theory, heat-trace asymptotics, and a geometric lattice whose boundary constant is exactly 4. We present a...
