Compounds of formulaand pharmaceutically acceptable salts thereof are described, as well as the pharmaceutical compositions containing said compounds and their pharmaceutically acceptable salts, and the use of said compounds and pharmaceutical compositions for the treatment, control or amelioration of AML. For downstream transmission, an optical line terminal generates a plurality of single wavelength optical signals having embedded time division multiplexed data streams. After exposing the RFID Probe to the RFID transceiver signal, the user removes the RFID Probe from the packed materials and observes the sensors on the probe. Lead assembly includes an insulated lead including a proximal end and a distal end, with at least one conductor therebetween; at least one electrode at the distal end of the lead and electrically connected to the at least one conductor, and a connector attached to the proximal end of the lead and adapted to be removably connectable to microdevice. The field effect transistor is configured to selectively connect the output signal to the output signal line device through the output in response to a reset of the driver signal.
