Deadzone compensation control based on detection of micro flow rate in pilot stage of proportional directional valve
The pilot operated proportional directional valves (POPDVs) with a flow rate ranging from 100 to 1000 L/min are widely used in electro-hydraulic systems (EHSs). The deadzone of the pilot stage valve and its control compensation...
Extreme Min – Cut Max – Flow Algorithm
In this article, the authors propose a maximum flow algorithm based on flow matrix. The algorithm only requires the effort to reduce the capacity of the underutilized arcs to that of the respective flow. The optimality of the...

Tracking differentiator based back-stepping control for valve-controlled hydraulic actuator system
Back-stepping design method is widely used in high-performance tracking control tasks As is known to all, the controller based on back-stepping design will become complex as the model order increases, which is the so called...
Cyclic adenosine 5′-diphosphate ribose analogs without a southern ribose inhibit ADP-ribosyl cyclase-hydrolase CD38
Joanna M. Swarbrick, Richard Graeff, Hongmin Zhang, Mark P. Thomas, Quan Hao, Barry V L Potter
Oct 23, 2014
Cyclic adenosine 5′-diphosphate ribose (cADPR) analogs based on the cyclic inosine 5′-diphosphate ribose (cIDPR) template were synthesized by recently developed stereo- and regioselective N1-ribosylation. Replacing the base...
