[Dynamic analysis of epileptic causal brain networks based on directional transfer function].

Epilepsy is a neurological disease with disordered brain network connectivity. It is important to analyze the brain network mechanism of epileptic seizure from the perspective of directed functional connectivity. In this paper, causal brain networks were constructed for different sub-bands of epileptic electroencephalogram (EEG) signals in interictal, preictal and ictal phases by directional transfer function method, and the information transmission pathway and dynamic change process of brain network under different conditions were analyzed.

Alternative Pathway to Phase Down Coal Power and Achieve Negative Emission in China.

Although widely recognized as the key to climate goals, coal "phase down" has long been argued for its side effects on energy security and social development. Retrofitting coal power units with biomass and coal co-firing with a carbon capture and storage approach provides an alternative way to avoid these side effects and make deep carbon dioxide emission cuts or even achieve negative emission. However, there is a lack of clear answers to how much the maximum emission reduction potential this approach can unlock, which is the key information to promote this technology on a large scale.

The perceived effectiveness and hidden inequity of postpandemic fiscal stimuli.

The world has committed trillions in fiscal expenditures to reboot the economy in the post–COVID-19 era. However, the effectiveness and the equity impacts of current fiscal stimuli are not fully understood. Using an extended adaptive regional input–output model, we assess the short-term impacts (2020 through 2022) of feasible stimuli on the global economy and the labor market.
