In the first line of table 1, the formula for m (kg) should be: 33 140 ρW(t s + 2t p )l 3 + m t in place of 33 140 ρW(t s + 2t p )l 3 + m t l 3 . In equation (2), the symbol m is in one spot placed in a subscript position when it should not be. The corrected formula is v M0 = mv b0 +Mv M0 + em(v b0 −v M0 ) M+m in place of v M0 = mv b0 +Mv M0 + e m (v b0 −v M0 ) M+m.

This paper describes the characterization of thin-film MEMS vibration energy harvesters based on aluminum nitride as piezoelectric material. A record output power of 85 μW is measured. The parasitic-damping and the energy-harvesting performances of unpackaged and packaged devices are investigated. Vacuum and atmospheric pressure levels are considered for the packaged devices. When dealing with packaged devices, it is found that vacuum packaging is essential for maximizing the output power. Therefore, a wafer-scale vacuum package process is developed. The energy harvesters are used to power a small prototype (1 cm 3 volume) of a wireless autonomous sensor system. The average power consumption of the whole system is less than 10 μW, and it is continuously provided by the vibration energy harvester.

Carbon and oxygen burning reactions, in particular, 12 C þ 12 C fusion, are important for the understanding and interpretation of the late phases of stellar evolution as well as the ignition and nucleosynthesis in cataclysmic binary systems such as type Ia supernovae and x-ray superbursts. A new measurement of this reaction has been performed at the University of Notre Dame using particle-γ coincidence techniques with SAND (a silicon detector array) at the high-intensity 5U Pelletron accelerator. New results for 12 C þ 12 C fusion at low energies relevant to nuclear astrophysics are reported. They show strong disagreement with a recent measurement using the indirect Trojan Horse method. The impact on the carbon burning process under astrophysical scenarios will be discussed.
