No evidence of an 11.16 MeV 2+ state in 12C

, 2012
An experiment using the 11B(3He,d)12C reaction was performed at iThemba LABS at an incident energy of 44 MeV and analyzed with a high energy-resolution magnetic spectrometer, to re-investigate states in 12C published in 1971.

Low-power-consumption road side unit deployment strategy for urban 2-D 5G Internet of vehicles

Tongxin xuebao
In urban Internet of vehicles (IoV) systems, the road side unit (RSU) was commonly deployed at road intersections to provide two-dimensional service coverage. However, due to vehicle dynamics, RSU might suffer from massive power waste.
