Migraine aura, a predictor of near-death experiences in a crowdsourced study [PDF]

PeerJ, 2019
Background Near-death experiences (NDE) occur with imminent death and in situations of stress and danger but are poorly understood. Evidence suggests that NDE are associated with rapid eye movement (REM) sleep intrusion, a feature of narcolepsy. Previous

Incidence of near-death experiences in patients surviving a prolonged critical illness and their long-term impact: a prospective observational study

Critical Care, 2023
Background So far, the few prospective studies on near-death experience (NDE) were carried out only in intensive care unit (ICU) patients with homogeneous aetiologies, such as cardiac arrest or trauma survivors.

Reality of near-death-experience memories: Evidence from a psychodynamic and electrophysiological integrated study

Frontiers in Human Neuroscience, 2014
The nature of near-death experiences (NDEs) is largely unknown but recent evidence suggests the intriguing possibility that NDEs may refer to actually perceived, and stored, experiences (although not necessarily in relation to the external physical world)

Monitoring of Post-Brain Injuries By Measuring Plasma Levels of Neuron-Derived Extracellular Vesicles

Biomarker Insights, 2022
Background: Extracellular vesicles (EV) released from neurons into the blood can reflect the state of nervous tissue. Measurement of neuron derived EV (NDE) may serve as an indicator of brain injury.

Accurate magnetic field imaging using nanodiamond quantum sensors enhanced by machine learning

Scientific Reports, 2022
Nanodiamonds can be excellent quantum sensors for local magnetic field measurements. We demonstrate magnetic field imaging with high accuracy of 1.8  $$\upmu $$ μ T combining nanodiamond ensemble (NDE) and machine learning without any physical models. We

Miniature mobile sensor platforms for condition monitoring of structures [PDF]

, 2009
In this paper, a wireless, multisensor inspection system for nondestructive evaluation (NDE) of materials is described. The sensor configuration enables two inspection modes-magnetic (flux leakage and eddy current) and noncontact ultrasound.

Reduced neutron widths in the nuclear data ensemble: Experiment and theory do not agree

, 2010
I have analyzed reduced neutron widths ({\Gamma}_{n}^0) for the subset of 1245 resonances in the nuclear data ensemble (NDE) for which they have been reported.

Benefits of Non-Destructive Evaluation and Probabilistic Damage Tolerance Cosimulation for Fracture Risk Reduction

e-Journal of Nondestructive Testing, 2023
In the context of the damage tolerance approach used to drive aircraft maintenance operations, it is essential to demonstrate the reliability of NDE inspections in detecting structural damage especially for additively manufactured components since this ...

Frequency Properties of an Air-Cored Coil and Application to Conductivity Measurement

IEEE Access, 2020
This study investigated the frequency properties of an air-cored coil and applied it to inspect conductivity change. Theoretical analysis and experimental study showed that what we measured is not the coil's own resistance and inductance but the ...
