Presented is the observation of a quadratic temperature dependence of the Cs 0-0 ground state hyperfine resonance frequency in a single Neon (Ne) buffer gas vapour microcell. The inversion temperature, expected to be theoretically independent of the buffer gas pressure, is measured to be about 80°C for two different samples. A proposal to develop chip scale atomic clocks with improved long-term frequency stability, simpler configuration (a single buffer gas instead of a buffer gas mixture) and then relaxed constraints on pressure accuracy during the cell filling procedure is presented. © 2010 The Institution of Engineering and Technology.

The main objective of the ParaDIME project has been to minimize energy consumption at all levels of the data center. On the one hand, we have considered what can be achieved on currently existing systems, via improvements of the programming model and the runtime system. On the other hand, we investigated which techniques and design decisions can make future computing nodes more energy efficient. We have successfully proposed and developed several methodologies that enable up to 60% energy savings in data center's components. © 2016 EDAA. Source
