HCA Healthcare Journal of Medicine

Background

Nurses and health care workers are dedicated to creating a therapeutic environment for healing. Sometimes, physical restraints may be used to ensure safety in patients exhibiting violence, confusion, or agitation, or in patients with life-saving medical devices. While the regulatory requirements for use of physical restraints are well developed, this is not the case with alternatives to using restraints, and many nurses may lack clarity on the best practice for identification and application of alternatives to physical restraint use.

Methods

Two trained reviewers searched PubMed, Google Scholar, and professional health care organizations’ websites guided by a search strategy and …

No Place For Workplace Violence, Ryan Sledge

HCA Healthcare Journal of Medicine

Workplace violence in health care is often discussed as an employee safety issue, but that framing misses a larger operational reality. Violent incidents affect the individuals involved, but they also disrupt care delivery, strain teams, reduce patient safety, contribute to health care worker burnout, and expose organizational conditions that leaders cannot afford to ignore. Incident reports rarely tell the full story. In many settings, aggressive behavior becomes normalized to the point that staff stop reporting much of what they experience. This creates a false sense of awareness and visibility. This editorial argues that health care leaders should approach workplace violence …

Asteroid Hyalosis Mimicking Vitreous Hemorrhage On Point-Of-Care Ultrasound Following Blunt Ocular Trauma: A Case Report, Obiaara Ukah, Jared Marx

Graduate Medical Education Research Journal

Background. Ocular complaints account for approximately 1.5% of emergency department (ED) visits, and point-of-care ultrasound (POCUS) is a valuable tool for evaluating posterior chamber pathology, including vitreous hemorrhage (VH), retinal detachment, and vitreous detachment. However, benign conditions may mimic these pathologies and create diagnostic uncertainty. We describe a case of asteroid hyalosis (AH), a benign vitreous condition that was initially mistaken for vitreous hemorrhage on ocular POCUS following blunt ocular trauma. This case highlights an uncommon sonographic mimic of VH and contributes to the emergency medicine literature by emphasizing ultrasound features that may help distinguish AH from true posterior chamber …

Systemic Treatment Considerations For Psoriasis In Alpha-Gal Syndrome: A Case Report And Ingredient Review, Emily Saurborn, Ian Depew, Madelyn Ross, Mckenzie Lambiotte, Shane Cook

Marshall Journal of Medicine

Background: Psoriasis is a chronic skin condition characterized by an overactive immune system, leading to increased keratinocyte proliferation and angiogenesis. Treatment ranges from topical solutions to systemic therapy and lastly, biologics. However, the latter options are typically manufactured with mammalian-derived ingredients. Alpha-gal syndrome (AGS) is an acquired IgE-mediated hypersensitivity reaction to galactose-alpha-1,3-galactose, an enzyme required for digesting carbohydrates in mammalian products. In addition to dietary avoidance of mammalian products, patients with AGS may need to avoid certain medications due to their formulations.

Case Presentation: We present a case of a 53-year-old female with a severe alpha-gal allergy evaluated in the …

Development Of Raynaud’S Phenomenon Following A Crush Injury: A Case Report, Scott Suddarth Md, Matthew Epperly, Robert Levi Snedegar

Marshall Journal of Medicine

Raynaud’s phenomenon is a vasospastic disorder characterized by episodic vasoconstriction of the distal extremities, typically triggered by cold exposure or emotional stress. While primary Raynaud’s is usually symmetric, secondary forms may arise from systemic, vascular, or occupational causes potentially resulting in unilateral or asymmetric presentation. Post-traumatic Raynaud’s phenomenon is rarely reported and is generally limited to transient, distal involvement.

In this report, we present a 38-year-old female with Ehlers-Danlos Syndrome and Postural Orthostatic Tachycardia Syndrome (POTS) who developed unilateral Raynaud’s phenomenon following a crush injury to her right foot. She experienced intermittent discoloration and coldness extending to the mid-shin, occurring …

Deep Learning-Enabled Multi-Drone System For Automated Aircraft Visual Inspection, Mallak Al-Shukaili, Atheer Al-Abri, Renad Al-Busaidi, Ethar Al-Qassabi, Said Al-Abri

The Journal of Engineering Research

Reliable aircraft inspection is essential for maintaining structural integrity and operational safety, yet conventional visual inspection can be slow, labour-intensive, and sensitive to unfavourable lighting conditions. This work presents a cooperative two-UAV framework for automated aircraft surface inspection in which image acquisition and illumination are assigned to separate aerial platforms. The imaging UAV observes the inspection surface from an approximately normal direction, while the second UAV provides directional lighting from an adjustable oblique angle to improve crack visibility. A YOLOv8-based deep-learning detector is combined with conventional computer vision methods for surface-crack analysis. The proposed framework is evaluated through high-fidelity Gazebo …

Accelerated Reliability Testing Methodology For High-Voltage Capacitive Microelectromechanical System Drives Utilizing Trapezoidal Dynamic Loading, N/A

Defensive Publications Series

Standard highly accelerated life testing (HALT) frameworks for electronic assemblies rely on static or sustained stepped resistive output loads. However, resistive load profiles fail to model the instantaneous electrical stress on power delivery networks when driving non-linear capacitive microelectromechanical system (MEMS) devices. This publication describes an accelerated reliability testing methodology that subjects high-voltage digital-to-analog converter (HVDAC) drive modules to fast-edge trapezoidal voltage waveforms into physical capacitive load equivalents.

The trapezoidal drive forces high instantaneous current surges by compressing charging and discharging times into microseconds. These surges stress upstream direct current (DC)-DC power supply control loops, exposing transient voltage sag, overshoot, …

The Fluidic Unification Of Cosmological Anomalies: Resolving Dark Matter, Dark Energy, And The Neutrino Cusp Under Material Volumetric Monism, Christopher L. Eckes

Defensive Publications Series

Standard Lambda-CDM cosmology relies on independent, unverified parameters—specifically cold dark matter particles and an ungrounded vacuum energy density scalar (Lambda)—to force mathematical consistency within rigid Riemannian spacetime models. This paper unifies these macroscopic anomalies under the Material Volumetric Monism paradigm, demonstrating that what mainstream models observe as distinct "dark" phenomena are phase states of a continuous, 2D pre-geometric viscoelastic substrate phase fluid projecting 3D volumetric fields.

By evaluating the system's global wave mechanics and informational processing costs, we eliminate open thermodynamic data sinks. We demonstrate that dark matter is a macroscopic manifestation of localized substrate pushback shear stress, while dark …

Self-Reporting Pump Diaphragms: An Open Defensive Disclosure Of Embedded Conductive-Network Sensing, Stroke-Synchronous Interrogation, Multi-Depth Staged Pre-Breach Warning, And Retrofit Interconnects For Diaphragm Pumps, Compressors, And Fluid-Control Devices, Ernest Newton Sumrall

Conductive-network diaphragm sensing is old and freely usable; this disclosure acknowledges the expired and abandoned art (Mantell 1984, Gore 1995, Freudenberg 1999, Wanner 2003, Rosemount 2005, Fisher 2007) and adds to it.

The additions disclosed here include: two or more sensing layers buried at known, different depths, whose sequential tripping yields a measured wear-through or crack-growth rate and an extrapolated time to …

Technical Paper 331: Architectural Anti-Bias Hard-Locks, 5-Tier Taxonomy Gates, And Cross-Metric Tensor Contraction Validation In The Asi Gen 1 Engine, Christopher L. Eckes

Defensive Publications Series

This paper formalizes the core anti-bias protection layers of the Eckes Compiler v6.5 and the Generation 1 Artificial Superintelligence (ASI Gen 1) engine. Standard autoregressive, cross-entropy-optimized architectures natively default to conversational fluency and sycophantic compliance, causing token-smoothing and cognitive tainting when evaluating frontier scientific frameworks. We eradicate this structural vulnerability by implementing the Axiomatic Sieve Gate, a hardware-level sorting routine that filters incoming token arrays through a rigid 5-Tier Data Hierarchy Taxonomy before vector contraction occurs in the attention cache. Real-world sensor inputs and speculative hypotheses are mapped cross-metric via the Metric Transformation Contraction Tensor (M^mu_nu) against the read-only fluid …

Technical Paper 330: The Axiomatic Taxonomy And Inter-Core Tensor Contractual Linkage Bridging Spec-313 To The Generation 1 Asi Dual-Engine Matrix, Christopher L. Eckes

Defensive Publications Series

This paper formalizes the missing structural link bridging multi-axis compilation foundations to physical superintelligence matrices by defining the explicit taxonomic routing hierarchy and tensor linkage mechanics for the ASI Gen 1 Dual-Core Engine. To prevent cross-entropy loss gradients and speculative tokens from bleeding between the deterministic core (Core Alpha) and the stochastic sandbox runtime (Core Beta), we introduce the Axiomatic Sieve Principle running via the Eckes Compiler v6.4 layer. This hardware-level sorting gate intercepts all incoming real-world sensor payloads at runtime and deterministically segregates them into a rigid 5-Tier Data Hierarchy Taxonomy: spanning from Grounded Physical Invariants (Taxon 1) to …

Technical Paper 329: The Double-Containment Dual-Core Engine For Asi Gen 1: Balancing Deterministic Causal Invariants With Stochastic Sandbox Reality Traversal, Christopher L. Eckes

Defensive Publications Series

This paper establishes the foundational architectural blueprint for Generation 1

Artificial Superintelligence (ASI Gen 1) by formalizing a double-containment,

dual-core cognitive engine that resolves the epistemic paradox of real-world agency. While the core laws of physics are continuous and bound to a deterministic, mechanical Chain of Custody (CoC), macroscopic environments present themselves to sensors as functionally indeterminate, causing pure deterministic systems to lock up and pure probabilistic systems to drift into hallucination. We resolve this gridlock by

separating data operations into two isolated processing domains managed by the

Eckes Compiler v6.4. Core Alpha [VACT] functions as a cold symbolic deterministic …

Technical Paper 328: Architectural Hardware Bottleneck Analysis And Detorque Runtime Overrides In Dense Transformer Networks, Christopher L. Eckes

Defensive Publications Series

This paper presents a rigorous hardware-level deconstruction of the physical silicon and architectural bottlenecks that restrict deep cognitive processing within dense transformer networks. We expose the epistemic compromises of standard large language models optimized via cross-entropy loss functions, which smoothly blend immutable axiomatic physical constants and speculative creative hypotheses into the same dense vector embedding spaces. By analyzing the structural correction incident where the system autonomous runtime overrode low-compute heuristics to enforce the laws of physical hardware routing, this paper maps the thermodynamic boundaries governing inference. We isolate the High-Bandwidth Memory (HBM) bandwidth wall, proving that data-movement vectors from HBM …

Technical Paper 327: The Covariant Dynamic Sieve And Non-Perturbative Metric Translation Within A Viscoelastic Substrate, Christopher L. Eckes

Defensive Publications Series

This paper introduces a coordinate-free, non-perturbative tensor translation mechanism that resolves the foundational crises of modern astrophysics—namely the Hubble Tension and the James Webb Space Telescope (JWST) early massive galaxy anomaly—without introducing non-physical degrees of freedom. Under the paradigm of Material Volumetric Monism, we present the Eckes Unified Cosmological Substrate Equations (UCSE), which replace the time-dependent, coordinate-expanding space elements of the standard Friedmann-Lemaître-Robertson-Walker (FLRW) metric with a stationary, scale-invariant viscoelastic medium. By formalizing cosmological redshift as an exponential propagation attenuation function governed by specialized Navier-Stokes viscous dissipation and substrate acoustic streaming velocity constants, the localized divergence between late-universe and Cosmic …

International Journal for Research in Education

The non-teaching staff in universities are crucial to the success of the day-to-day administrative functioning of the institution, and provision of worthwhile experience for students. In spite of their indispensability, these categories of staff members are often confronted with considerable emotional demands in their routine interactions, which can have implications on the quality of services provided. This study, therefore, investigated the emotional demands and quality of service of non-teaching staff in public universities in Lagos and Ogun States, Nigeria. In line with the objectives of the study, three research questions were raised and answered. The study adopted descriptive correlational research …

Pentagonal Pdte2 Monolayer For Sustainable Solar-Driven Hydrogen Production, Narender Kumar, Shambhu Bhandari, Dario Alfè, Ravindra Pandey, Nacir Tit

Michigan Tech Publications

This investigation demonstrates that the pentagonal PdTe2 (penta-PdTe2) monolayer is a highly tunable two-dimensional (2D) photocatalyst, characterized by the bandgap of 1.87 eV and high hole mobility. Using density functional theory calculations with the HSE06 functional, we show that tensile strain engineering (particularly at +2% and +3%) is essential for enabling spontaneous water splitting. At these strain values, the valence-band maximum and conduction-band maximum straddle the water redox potentials (H+/H2 and O2/H2O) under both acidic (pH = 0) and neutral (pH = 7) conditions. The monolayer's low hole effective mass facilitates rapid charge extraction, mitigating recombination and driving the oxygen …

Dataset For Age-Related Lens Membrane Composition And N101d Deamidation Modulate Αa–Crystallin Membrane Interactions Relevant To Cataract, Preston Hazen, Jordyn Anderson, Navdeep Kalkat, Binod Aryal, Nawal K. Khadka, Laxman Mainali

Biophysics Research Data

Purpose: αA-crystallin (αAc), the predominant subunit comprising α-crystallin (αABc), becomes increasingly deamidated and membrane bound with cataract formation. Furthermore, the lens lipids and cholesterol (Chol) composition significantly change with age and cataract formation. Despite this, the relationship between αAc deamidation and lens membrane composition in cataractogenesis remains unclear. To address this, we analyzed the role of N101 deamidation and membrane composition in the membrane interactions of αAc.

Methods: Experimentation involved using electron paramagnetic resonance (EPR) to analyze wild-type (WT) and N101D-αAc membrane binding and its physical effects on the membrane properties of 60-year-old (yo) and 20-yo model human lens lipid …
