Terminal, base station, and communication method
In a terminal (200), a Pre-IFFT unit (204) generates a signal waveform for multicarrier transmission (OFDM) or single carrier transmission (DFT-s-OFDM) in uplink.

Gradient based boundary filtering in intra prediction
After initial intra prediction based on projection along an intra prediction direction, there may exist discontinuities between the predicted block and neighboring blocks. To smooth the block boundary, boundary filtering may be used with intra prediction. In particular, different methods may be used for boundary filtering.

Plasmon-assisted photothermoelectric effect based detection of infrared radiation on asymmetrically patterned graphene
Various methods and devices for ultrasensitive infrared photodetection, infrared imaging, and other optoelectronic applications using the plasmon assisted thermoelectric effect in graphene are described.
