Various technologies have been developed to reduce CO2 emissions and achieve net-zero energy sectors. One common method is carbon capture and storage, which traps CO22 using special materials. However, they are facing challenges in handling the captured CO2 for long-term storage and potential secondary emissions. Converting CO2 into useful products...

Vital signs, such as heart and respiratory rate, provide critical insight into a person’s health. Radar has been used to remotely analyze and detect human activity and vital signs for many years. Despite all the great features such as motion sensitivity, privacy preservation, penetrability, and more, radar has limited spatial degrees of freedom...

Orthogonal time frequency space (OTFS) modulation has the potential to enable robust communications in highly mobile scenarios. This is due to multiplexing information-bearing data into nearly-constant channels in the delay-Doppler domain instead of the time-frequency domain, which makes communication more resilient to fast changes in the channel....
