Synchronization of Coupled Boolean Phase Oscillators
, 2014 We design, characterize, and couple Boolean phase oscillators that include state-dependent feedback delay. The state-dependent delay allows us to realize an adjustable coupling strength, even though only Boolean signals are exchanged.

Hardware implementation of cascaded H-bridge inverters
, 2016 Medium Voltage (MV) converters have lately been quite popular for high power motor drives. Variable speed control of the motor and the drop in the energy loss i.e. increase in efficiency of the system are the main advantages of these drives. These MV converters are widely used in industries for fans, driving pumps, and marine propulsion system of ships.

International Journal of Cancer, EarlyView.Abstract Genetic tumor risk syndromes (genturis) contribute substantially to the overall cancer burden and provide opportunities for early detection, prevention, and individualized treatment. Yet, many affected individuals remain undiagnosed due to restrictive testing criteria and challenges in variant interpretation.

Limnology and Oceanography: Methods, EarlyView.Abstract Estimating exchange rates of submarine groundwater discharge (SGD) at high temporal resolution over extended periods remains challenging, particularly when using heat as a tracer in highly dynamic environments such as tidal systems. Currently available heat transport models struggle to accurately quantify SGD exchange rates in these settings ...
