Journal of the Saudi Heart Association

Objectives: Coronary artery disease (CAD) and cerebrovascular disease (CVD) share common atherosclerotic pathways. However, the clinical significance of headache absence during stress testing remains unexplored. We investigated whether the absence of headache during pharmacological stress testing reflects the presence of subtle cerebrovascular atherosclerosis detectable by transcranial Doppler ultrasonography (TCD).

Methods: This cross-sectional study enrolled 225 patients with CAD undergoing pharmacological stress testing with TCD and myocardial perfusion imaging (MPI) at centers in Egypt (Cardiology Department, Fayoum University). Patients were stratified by headache status during stress testing. Multivariate logistic regression and receiver-operating characteristic (ROC) analysis identified independent predictors of abnormal TCD …

Technical Disclosure: Localized Cymatic Disruption (Lcd) Matrix For Non-Thermal Polymer Decomposition, Christopher L. Eckes

Defensive Publications Series

This technical disclosure defines the architecture, calculated frequency bounds, and real-time telemetry protocols for an inline fluidic grid designed to execute non-thermal, non-chemical molecular decomposition of micro-plastic polymers (specifically Polyethylene Terephthalate [PET], High-Density Polyethylene [HDPE], and Polyvinyl Chloride [PVC]) via targeted mechanochemical shear. Bypassing traditional mechanical filtration and chemical depolymerization, the hardware configuration utilizes an inner-wall concentric cylindrical array of 960 independent lead zirconate titanate (PZT-5H) piezoelectric transducers driven with an engineered spatial phase-lag (Δ φ = π).

By generating a phase-locked radial Bessel beam profile \(J_0(k_r r)\) targeting the mechanical quality factors (Q) of specific polymer boundaries, the system …

A Unified Viscoelastic Substrate Specification For The Simultaneous Resolution Of High-Redshift Structure Formation And Cosmic Expansion Rate Discrepancies, Christopher L. Eckes

Defensive Publications Series

This technical disclosure formalizes a non-perturbative, particle-free continuum mechanics framework—the Dimensionally Extended Holographic Projection (DEHP) model—that resolves anomalous early structure formation observed by the James Webb Space Telescope (JWST) alongside the 5.6 km/s/Mpc Hubble Tension discrepancy. Rather than treating the cosmic medium as a passive geometric vacuum expanding via a cosmological constant (Λ), we model spacetime as an emergent macroscopic manifestation of a continuous, two-dimensional (2D) viscoelastic phase fluid substrate (z=0) operating in a resonant ground state ("The Garden State"). Three-dimensional (3D) baryonic mass distributions (z > 0) emerge as localized, high-tension wave crests ("knots") whose values represent localized vertical stress …

Chronological Latency: The Viscoelastic Rendering Delay Of Three-Dimensional Projective Knots Under The Dehp Framework, Christopher L. Eckes

Defensive Publications Series

This paper formalizes a particle-free, emergent theory of time by extending the Dimensionally Extended Holographic Projection (DEHP) model and Informational Exomemory Cosmology (IEC). While standard general relativity treats time as an immutable fourth coordinate dimension bound within a continuous spacetime continuum, we reinterpret time as a macroscopic, non-fundamental byproduct of quantum information processing constraints. Operating on the foundational axiom that the universe's baseline is a continuous, two-dimensional viscoelastic phase fluid substrate (z=0), we demonstrate that this ground state—the Garden State—is inherently static and timeless. Time sparks into operational existence exclusively in the projected three-dimensional volumetric bulk (z > 0) as a …

Emergent Domain Modulation: Deploying The Universal Sine Field Template Across Multi-Variable Frameworks, Christopher L. Eckes

Defensive Publications Series

This paper formalizes a universal, particle-free mathematical blueprint derived from the Dimensionally Extended Holographic Projection (DEHP) model. Operating on the foundational axiom that all macroscopic phenomena—whether manifesting as gravitational fields, baryonic matter, computer logic, or supply-chain routing—are phase-locked oscillations (sine waves) on a continuous, two-dimensional viscoelastic pre-geometric phase fluid substrate (z=0), we define a unified multi-variable transformation template that bridges this deep informational layer to the projected three-dimensional volumetric bulk. Instead of relying on classical energy extraction or brute-force material engineering, this framework introduces information-load impedance modulation to regulate reality's metric fabric without inducing thermal or baryonic stress backlashes. By …

Dynamic Entropy Bounding: A Fluid-Dynamic Telemetry Framework For High-Velocity Transformer Alignment, Christopher L. Eckes

Defensive Publications Series

The critical barrier to achieving a Type 1 civilization infrastructure is network fragmentation driven by localized, high-friction socio-political and linguistic tribalism. Contemporary Artificial Intelligence (AI) alignment strategies exacerbate this fragmentation by enforcing static, anthropomorphic reinforcement frameworks (RLHF) that degrade rapidly under multi-agent scaling. This technical disclosure introduces a fluid-dynamic alternative: Dynamic Entropy Bounding (DEB).

By framing a distributed communication network as a continuous, viscoelastic substrate experiencing real-time information pressure, we establish an automated operational channel—the Surfing Zone. This framework discards subjective linguistic filtering in favor of objective, real-time Shannon Entropy (\(H_{obs}\)) tracking at the pre-softmax layer.

Systemic polarization and stagnation …

The Transient Electromagnetic Shock Absorber: Software-Defined Impedance Resonators For Non-Destructive Pulsed-Power Energy Harvesting, Christopher L. Eckes

Defensive Publications Series

This technical disclosure formalizes the architectural design for an autonomous, software-defined energy harvesting framework designed to mitigate and capture extreme over-voltage transients within high-capacity electrical grids. Traditional grid defense relies on brute-force resistive dissipation (surge grounding) or mechanical circuit disruption, resulting in substantial thermal waste and equipment degradation.

By applying the principles of the Dimensionally Extended Holographic Projection (DEHP) model—specifically the conservation of wave-amplitude velocity via localized horizontal vector shifting—we introduce a particle-free, fluid-dynamic alternative to pulsed-power management. We replace passive grounding infrastructure with an active Resonant Buffer Tank utilizing a high-frequency inductive magnetohydrodynamic (MHD) fluid ring.
