Bidirectional wakes over complex terrain using SCADA data and wake models [PDF]

Wind Energy Science
We investigate bidirectional wake effects between two wind turbines of the same type in a hill region in northern Japan using supervisory control and data acquisition (SCADA) data and validate the simulated wakes using 12 wake models. The extent to which

Effect of Propeller Suction on Wake

Journal of the Society of Naval Architects of Japan, 1975
To examine the relation between effective wake fraction and propeller thrust loading coefficient, the contraction of flow in front of a propeller due to propeller suction was studied by use of the flow visualization method. It was shown that the rate of the contraction depends mainly upon the propeller thrust loading coefficient and is nearly estimated

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Incident flow effects on the performance of piezoelectric energy harvesters from galloping vibrations

Theoretical and Applied Mechanics Letters, 2014
In this paper, we investigate experimentally the concept of energy harvesting from galloping oscillations with a focus on wake and turbulence effects. The harvester is composed of a unimorph piezoelectric cantilever beam with a square cross-section tip ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Large-eddy simulation of the effects of horizontal and vertical adjustments in a wind farm

Frontiers in Energy Research
In order to study the fine structural characteristics of the wind field and wind power generation in wind farms, large-eddy simulations (LES) with different layouts are carried out under a given wind direction.

A New Analytical Wake Model for Yawed Wind Turbines

Energies, 2018
A new analytical wake model for wind turbines, considering ambient turbulence intensity, thrust coefficient and yaw angle effects, is proposed from numerical and analytical studies.

Vestibular Patient Journey: Insights From Vestibular Disorders Association (VeDA) Registry

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Vestibular symptoms impose a high burden of disability. Understanding real‐world diagnostic and treatment pathways can identify care gaps and guide interventions. We aimed to characterize symptom profiles, diagnostic trends, provider involvement, and treatment patterns in vestibular disorders.

Sleeping and Waking Thought: Effects of External Stimulation [PDF]

Sleep, 1986
This article describes some of the variables that distinguish waking and sleeping (REM) thought. Mentation reports from the waking state, as described here, tend to have more topic shifts than those from the REM state, which often have a single-theme storylike quality. It is assumed that heightened response thresholds to sensory stimuli, in conjunction
