Frequency-modulated nuclear localization bursts coordinate gene regulation [PDF]
, 2008 In yeast, the transcription factor Crz1 is dephosphorylated and translocates into the nucleus in response to extracellular calcium. Here we show, using time-lapse microscopy, that Crz1 exhibits short bursts of nuclear localization (typically lasting 2 ...

IEEE Transactions on Industrial Informatics, 2021 Battery swapping stations (BSSs) are ideal candidates for fast frequency regulation services (FFRS) due to their large battery stock capacity. In addition, BSSs can precharge batteries for customers and the batteries that are not in charging can provide ...

Improved Frequency Control Strategy for Offshore Wind Farm Integration via VSC-HVDC
Energies, 2022 Voltage source converter based high voltage DC system (VSC-HVDC) has become a very promising solution to integrate offshore wind farm. However, the equivalent inertia of the modern power system with large renewable energy integration becomes small, which

Swing Dynamics as Primal-Dual Algorithm for Optimal Load Control [PDF]
, 2012 Frequency regulation and generation-load balancing are key issues in power transmission networks. Complementary to generation control, loads provide flexible and fast responsive sources for frequency regulation, and local frequency measurement capability

Impact of variability, uncertainty and frequency regulation on power system frequency distribution [PDF]
2016 Power Systems Computation Conference (PSCC), 2016 This work originates from the observation of the frequency distribution of the Irish system as obtained from a Frequency Disturbance Recorder lent to the last author by the University of Tennessee. The probability density function of such a distribution appears to be bimodal.
