There is provided a computer-implemented method of performing sentiment analysis. The flag modification enable bit is typically sent with the operation code and other information in the native instruction and is set to allow updating of one or more flags, such as stored in flag registers, associated with non-native instructions, such as variable length instructions. Channel edge defining electrodes 24 and 26 are disposed either side of the channel 28, in place of channel stops, removing the effects of spurious charges generated in the channel in the regions of amplification. Further provided are a transparent thin film formed using the photoresist composition and a liquid crystal display device comprising the thin film. The transmitter is also adapted to operate according to the selected amplifier operating class to communicate a signal to an antenna.
