Ion-Cyclotron Wave Excitation by Double-Resonance Coupling (1991)

Fasoli, A., Good, T. N., Paris, P. J., Skiff, F., Tran, M. Q.

A modulated high frequency wave is used to remotely excite low frequency oscillations in a linear, strongly magnetized plasma column. An electromagnetic wave is launched as an extraordinary mode...

MELD scoring system is useful for predicting prognosis in patients with liver cirrhosis and is correlated with residual liver function: a European study

Botta, F, Giannini, E, Romagnoli, P, Fasoli, A, Malfatti, F, Chiarbonello, B, ...

Background: Indices for predicting survival are essential for assessing prognosis and assigning priority for liver transplantation in patients with liver cirrhosis. The model for end stage liver...

Platelet count/spleen diameter ratio: proposal and validation of a non-invasive parameter to predict the presence of oesophageal varices in patients with liver cirrhosis

Giannini, E, Botta, F, Borro, P, Risso, D, Romagnoli, P, Fasoli, A, ...

Background and aims: Cirrhotic patients frequently undergo screening endoscopy for the presence of oesophageal varices (OV). In the future, this social and medical burden will increase due to the...

Cross-field transport by instabilities and blobs in a magnetized toroidal plasma

Podesta, M., Fasoli, A., Labit, B., Furno, I., Ricci, P., Poli, F.M., ...

The mechanisms for anomalous transport across the magnetic field are investigated in a toroidal magnetized plasma. The role of plasma instabilities and macroscopic density structures (blobs) is...
