Temperature dependence of neutron-induced soft errors in SRAMs

We irradiated commercial SRAMs with wide-spectrum neutrons at different temperatures. We observed that, depending on the vendor, the soft error rate either increases or slightly decreases with temperature, even in devices belonging to the same technology node. SPICE simulations were used to investigate the temperature dependence of the cell feedback time and restoring current. The shape and magnitude of the particle-induced transient current is discussed as a function of temperature. The variability in the response is attributed to the balance of contrasting factors, such as cell speed reduction and increased diffusion with increasing temperature. (C) 2011 Elsevier Ltd.

Drivers of tight carbon control in the context of climate change regulation

Our study examines the drivers of tight budgetary control in carbon management in the context of climate change regulation. Using the setting of New Zealand Emissions Trading Scheme (ETS), our study explores how firms manage their carbon performance using carbon‐focused budgetary control. Based on a survey data from New Zealand firms, including both those with and those without an ETS compliance obligations, our results suggest that economic and regulatory environmental pressures, the level of proactiveness of emissions management strategy, the level of integration of carbon issues in strategic and operational processes and the perceived importance of carbon issues are the significant drivers of tight carbon‐focused budgetary control
