The present invention relates to the phosphohistidine analogs of the present invention which of the formulaand the hapten containing the residue of same. The proposed method uses online learning algorithm based on the theory of multi-armed bandit to perform antenna state selection. By providing the indication, such as an indication the data packets are of low priority or are generated or received by a machine type communication application, the mobile communications network can control communication of the data packets from the communications bearer differently to data packets communicated via other communications bearer having a higher priority. The method further includes receiving by the control panel, in response to actuation of the testing actuator in the presence of the predetermined condition, a transmission from the sensor indicating that the control panel should not report to a monitoring station. The new model can also be used to control a precursor injection apparatus to achieve a desired germanium concentration.
