Femoropopliteal angioplasty: can we predict success with duplex sonography?

Bubble CPAP: can we predict success or failure?

Current modalities of ventilatory assistance in the management of respiratory distress syndrome (RDS) in preterm infants range from continuous positive airway pressure (CPAP) to various modes of mechanical ventilation. The use of CPAP has been associated with a lower incidence of chronic lung disease when used as the initial respiratory support. In contrast, mechanical ventilation has the poten...

Balloon Angioplasty in Patients With Femoropopliteal Occlusions

In 12 patients (aged 64±10 years) with femoropopliteal occlusions (1-27 cm; average, 8.4 cm length) that could not be recanalized by standard guidewire-balloon angioplasty techniques, percutaneous laser-assisted balloon angioplasty was performed by use of a new fluorescenceguided dual-laser system. Plaque detection by 325-nm laser-excited fluorescence spectroscopy provided real-time feedback co...

Coronary angioplasty--what can we reasonably expect?

Bubbles , Can We Spot Them ? Crashes , Can We Predict Them ?

Johansen and Sornette proposes that the crash has fundamentally an endogenous origin and exogenous shocks only serve as triggering factors. This endogenous force is shown in price as power law log-periodicity (PLLP) signature prior to a crash. We estimate the highly nonlinear model developed by them using a hybrid approach which combines scatter search, genetic adaptor and tabu search. The mode...

Can we predict safety culture?

Safety culture is broadly recognized as important for Air Traffic Management and various studies have addressed its characterization and assessment. Nevertheless, relations between safety culture and formal and informal organizational structures and processes are yet not well understood. We aim to improve the understanding of these relations by agent-based organizational modeling and thus provi...
