International Journal of Finance &Economics, EarlyView.ABSTRACT This paper studies herding and anti‐herding behaviour in three European stock markets before and during the Covid‐19 pandemic by employing both static and dynamic analysis. We examine four different questions related to herding behaviour: (i) Did herding behaviour increase during the pandemic? (ii) Does herding behaviour respond differently in

InfoMat, EarlyView.Irreversible calcium (Ca) plating and stripping pose significant challenges for Ca metal batteries due to the formation of an ion‐insulating passivation layer. This study demonstrates that ionic covalent organic frameworks (iCOFs) serve as effective artificial protective layers for Ca metal anodes, facilitating rapid Ca2+ transport and promoting ...

Circuit breakers for addiction [PDF]
Internal Medicine Journal, 2007 AbstractThe phenomenon of addiction is complex, although its expression clinically is relatively straightforward. There is a series of neurophysiological changes that mediate changes in the mesolimbic and mesocortical systems which in turn lead to disturbances in reward mechanisms.
