Open AccessCirc_0001421 facilitates glycolysis and lung cancer development by regulating miR-4677-3p/CDCA3
Lung cancer (LC) is a malignant tumor originating in the bronchial mucosa or gland of the lung. Circular RNAs (circRNAs) are proved to be key regulators of tumor progression. However, the regulatory effect of ...

Validation of dynamic cavitation model for unsteady cavitating flow on NACA66
Unsteady cavitating flow is extremely complicated and brings more serious damages and unignorable problems compared with steady cavitating flow. CFD has become a practical way to model cavitation; however, the...

Open AccessCharacteristics of onset and dam** in a standing-wave thermoacoustic engine driven by liquid nitrogen
We explore characteristics of onset and dam** in a thermoacoustic engine (TE) driven by cryogens instead of conventional heat sources above the ambient temperature by a comprehensive study of a self-made sta...

Open AccessModeling cavitation flow of cryogenic fluids with thermodynamic phase-change theory
Cavitation is the formation of vapor bubbles within a liquid where the flow dynamics causes the local static pressure to drop below the vapor pressure. The so-called full cavitation model (FCM) developed by Si...

Study on the onset temperature of a standing-wave thermoacoustic engine based on circuit network theory
Onset mechanism is one of the most fundamental issues in thermoacoustic field. However, the onset conditions and the phenomena happening in the onset process have not been well explained theoretically. In this...
