Our event processing platform is built over reconfigurable hardware-FPGAs-to achieve line-rate processing. Furthermore, our event processing engine supports Boolean expression matching with an expressive predicate language that models complex financial strategies to autonomously buy and sell stocks based on real-time financial data.

As-deposited sputtered HfO2 thin films have large number of defects resulting in increased oxide charge and leakage current. In this paper the effect of sputtering voltage, bias sputtering and post deposition thermal annealing is investigated. The I–V and C–V characteristics of the dielectric film are studied employing Al–HfO2–Si MOS capacitor structure. It is found that oxide charge increases with increasing sputtering voltage. Thermal annealing in oxygen reduces the interface/oxide charges and leakage current. It is shown that applying substrate bias during film deposition leakage current is further reduced by an order of magnitude. The microstructure of thin film is examined by AFM. The reduction in surface roughness with bias sputtering is shown. The experimental results are presented and discussed for device application.

Six months later he was treated with oral miltefosine on a compassionate basis as an off-label indication. Miltefosine was given 100mg daily in divided doses for an initial 8 weeks. Due to insufficient response, the treatment was extended up to a total of 12 weeks. The patient showed an excellent response to treatment, and after 12 months of follow-up there was complete healing of all cutaneous lesions. Oral miltefosine appears to be an important alternative for the treatment of PKDL in India and confirmatory studies in controlled clinical trials are needed.
