Characteristics of unsteady flow around a vehicle affecting its high-speed stability during a dynamic steering action

Nihon Kikai Gakkai ronbunshu, 2014
In order to clarify unsteady flow structure’s behavior that improves vehicle’s high-speed stability during steering input, on-road analysis was conducted.

Of dreaming and wakefulness

Neuroscience, 1991
Following a set of studies concerning the intrinsic electrophysiology of mammalian central neurons in relation to global brain function, we reach the following conclusions: (i) the main difference between wakefulness and paradoxical sleep lies in the weight given to sensory afferents in cognitive images; (ii) otherwise, wakefulness and paradoxical ...

Sleep EEG Derived From Behind-the-Ear Electrodes (cEEGrid) Compared to Standard Polysomnography: A Proof of Concept Study

Frontiers in Human Neuroscience, 2018
Electroencephalography (EEG) recordings represent a vital component of the assessment of sleep physiology, but the methodology presently used is costly, intrusive to participants, and laborious in application.

Evolution of Wake Vortices and Energy Characteristics of Mixed-flow Pumps Under Stall Conditions [PDF]

Journal of Applied Fluid Mechanics
Unsteady wake dynamics and associated energy dissipation mechanisms in mixed-flow pumps remain critical challenges detrimentally affecting operational stability and efficiency, particularly under off-design operating conditions.

Numerical Study of the Effect of Rail Modelling Method on Train Aerodynamic Performance and Slipstream [PDF]

Journal of Applied Fluid Mechanics
The high-speed movement of trains generates train-induced wind, commonly referred to as slipstream, which presents a specific safety concern for passengers and personnel.

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions

Journal of Physics: Conference Series, 2023
Abstract In this paper, we propose a new non-symmetric Gaussian wake model, which allows for different lateral expansions on the two sides of a wake to account for its interaction with neighbouring wakes. The proposed model is formulated following classical speed-deficit assumptions and momentum conservation.

Wake-up (or Wake-up for) Stroke: A Treatable Stroke [PDF]

The Neuroradiology Journal, 2013
A 74-year-old man was admitted to the Emergency Room of our institution with worsening dysarthria, left-side weakness and hypoesthesia (NIHSS score: 5) since his awakening at 7:30 a.m. The evening before, he had gone to sleep at 10:30 p.m. Brain computed tomography (CT) and cervicocranial CT angiography showed low density attenuation of the right ...

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.

Measurement of mean fields in the intermediate wake of a heated cylinder

Nihon Kikai Gakkai ronbunshu, 2019
Measurements are made by a newly designed high-precision thermo-anemometer in the wake of a heated cylinder of D=0.013 and 0.030 m. The purpose of this work is to make clear the effects of cylinder heating on the mean field in the wake.
