Numerical analysis of offshore wind-farm-induced drag effects on coastal upwelling dynamics

Flow
Wind farms extract momentum from the atmospheric flow, generating wind-speed deficits both within the plant, and extending downstream. When located offshore, these deficits modulate air–sea coupling, potentially impacting coastal upwelling in sensitive ...

Turbulent flow past idealised arrays of photovoltaic panels: an experimental study

Flow
We experimentally investigated the turbulent flow in a water channel developing past a two-dimensional array of photovoltaic panels, with varying incidence angle and spacing.

Decreased expression of miR-939 contributes to chemoresistance and metastasis of gastric cancer via dysregulation of SLC34A2 and Raf/MEK/ERK pathway

Molecular Cancer, 2017
The development of chemoresistance and metastasis are the leading causes of death for gastric cancer (GC) patients, however, the molecular mechanisms involved remain unclear.

Coronary Serum Exosomes Derived from Patients with Myocardial Ischemia Regulate Angiogenesis through the miR-939-mediated Nitric Oxide Signaling Pathway

Theranostics, 2018
Rationale: Angiogenesis is a crucial step towards tissue repair and regeneration after ischemia. The role of circulating exosomes in angiogenic signal transduction has not been well elucidated. Thus, this study aims to investigate the effects of coronary

Platelet microparticle-mediated transfer of miR-939 to epithelial ovarian cancer cells promotes epithelial to mesenchymal transition

OncoTarget, 2017
Epithelial ovarian cancer (EOC) patients frequently suffer from thrombocytosis, which leads to a poor prognosis. However, the mechanism underlying platelet regulation of biological behavior in EOC remains unclear.

Inferring free surface disturbance properties from Kelvin wakes using convolutional neural network

Flow
Kelvin wakes are fluid motions generated by a moving disturbance at a free surface. We present a machine learning-based framework for inferring the properties of such moving disturbances from the Kelvin-wake patterns.

A large-eddy simulation study of water tunnel interference effects for a marine propeller in crashback mode of operation

Flow
Marine propellers are studied in design and off-design modes of operation like crashback, where the propeller rotates in reverse while the vehicle is in forward motion.
