On-campus over-the-air millimeter-wave channel evaluation for connected and automated mobility

High throughput wireless communication between vehicles and infrastructure will rely on millimeter-wave carriers and technology, which provide access to large bandwidths whilst still being able to establish stable links over distances of hundreds of meters. The work presented here, evaluates the quality of such signals in a mini-urban campus environment, by comparing detailed channel sounding results with signal quality parameters such as the error vector magnitude and the established data throughput. This provides insights into the relationships between fundamental parameters used to establish channel models and the quality of service parameters used in applications and standards. For the environment investigated, a strong threshold dependence of the signal quality on the received power is observed and explained in detail

Calcium-binding protein, parvalbumin, is reduced in mutant mammalian muscle with abnormal contractile properties.

To elucidate the biochemical basis of hereditary muscle diseases in an experimental mammal, we performed polypeptide analyses on skeletal muscles of neuromuscular mutants of the mouse. In one of these, "arrested development of righting response" (adr), the concentration of the soluble Ca2+-binding protein parvalbumin was drastically reduced in comparison to wild type. This reduction was not an unspecific consequence of muscle disease, as it was not observed in two other neuromuscular mouse mutants, "wobbler" (wr) and "motor endplate disease" (med or medjo). Isometric twitches of adr muscle had only slightly prolonged contraction and half-relaxation times, yet long-lasting after-contractions were observed upon repeated (20-100 Hz) direct stimulation. Thus, parvalbumin may be mainly involved in the relaxation after tetanic contraction of fast-twitch fibers

Over-the-air testing for autonomous vehicle communications

The future of transportation lies with the development of connected and automated mobility (CAM) solutions, which include intelligent and self-driving vehicles, with a large research and engineering community investigating and overcoming the technical challenges in their development. Although safest CAM solutions are expected to be autonomous and fully self-supporting, the ability to receive and share information with other vehicles or infrastructure holds promise to lead to advanced environment and traffic awareness as well as cooperative behaviour functions. Fast and reliable wireless communication between vehicles and infrastructure will likely rely on 5G NR and beyond technology, with access to already existing cellular communication infrastructure as well as to newly deployed infrastructure for the higher frequency bands that provide access to larger bandwidths. The work presented here, evaluates the quality of such over-the-air, vehicle-to-infrastructure signals in a mini-urban campus environment for both low and high carrier frequencies, by comparing the results from detailed channel sounding measurements with signal quality parameters such as the error vector magnitude and the established data throughput. This provides insights into the relationships between fundamental parameters used to establish vehicular communication channel models and the quality of service parameters used in vehicular applications and international standards
