Engineers at Tokyo Institute of Technology (Tokyo Tech) have demonstrated a simple computational approach for improving the linearization of power amplifiers (PA), such as those used in mmWave systems and other telecommunication systems. The proposed technique involves training small neural networks to directly estimate the coefficients of a polynomial for digital pre-distortion (DPD) based on their frequency response during calibration sweeps.

Emeritus Professor/Specially Appointed Professor Fumio Koyama of the Institute of Innovative Research, Tokyo Institute of Technology was awarded the 4th Hirose Award from Hirose Foundation. The award ceremony and commemorative lecture took place on March 23, 2024.

Tokyo Tech's Student Initiative Support Services, an arm of the Student Success Support Section within the Student Support Center, hosted the 17th Student Support Forum at Hisao & Hiroko Taki Plaza on Ookayama Campus on February 29.

Genotypic convergence involving the loss of multiple genes required for gastric function could explain the evolution of different stomachless (or agastric) ray-finned fishes, according to a new study by Tokyo Tech researchers. Based on preliminary research identifying slc26a9 gene loss in agastric fishes compared to gastric fishes, the researchers further compared gene losses between agastric and gastric fishes to arrive at their findings, which revealed convergent gene losses and pseudogene-forming inactivations in agastric fishes.

Helicines are known for their excellent circularly polarized luminescence properties but synthesizing them via conventional methods often leads to distortions in the molecular structure, impacting the optical properties and stability of the molecules, an issue recently overcome by researchers from Tokyo Tech. They developed a strategy for enantioselective synthesis of carbo[11] and [13]helicenes. The synthesized materials exhibited low distortions and showed CPL brightness as high as 513 M–1 cm–1.
