Background Patients with pancreas divisum may develop pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosing pancreas divisum. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive test reported to be highly accurate in diagnosing pancreas divisum. Aim To evaluate the diagnostic accuracy of MRCP in detecting pancreas divisum at our...
Although CuIn1-xGaxSe2-ySy (CIGS) chalcopyrite and Cu2ZnSn(S,Se)4 (CZTSSe) kesterite-related films offer significant potential for low-cost high-efficiency photovoltaic (PV) devices, the complicated multi-element nature of these materials generally leads to the requirement of more complex and costly deposition processes. This talk focuses on employing the unique solvent properties of hydrazine to...
The problem of pole positioning is considered when the parameters of linear, time invariant systems are unknown. A specific parameter adaptive philosophy is proposed and conditions for convergence of the paramerer identifier are presented. A stable and unstable open-loop model are then implemented with the above adaptive scheme to assess its performance characteristics.
