On choosing the start time of binary black hole ringdown [PDF]

Physical Review D, 2017
The final stage of a binary black hole merger is ringdown, in which the system is described by a Kerr black hole with quasinormal mode perturbations. It is far from straightforward to identify the time at which the ringdown begins.

Energy storage for black start services: A review [PDF]

International Journal of Minerals, Metallurgy and Materials, 2022
AbstractWith the increasing deployment of renewable energy-based power generation plants, the power system is becoming increasingly vulnerable due to the intermittent nature of renewable energy, and a blackout can be the worst scenario. The current auxiliary generators must be upgraded to energy sources with substantially high power and storage ...

Starting with I: Combating Anti-Blackness in Libraries [PDF]

Medical Reference Services Quarterly, 2021
When millions saw footage of George Floyd's murder by police during the COVID-19 pandemic where marginalized groups had higher death rates, increased awareness and action arose because Black people are treated differently in the United States. Many libraries subsequently created statements and committees to commit to reduce inequities in libraries ...
