Deep Underground Science and Engineering, EarlyView.The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

Distributed PLL-based control of offshore wind turbines connected with diode-rectifier based HVDC systems [PDF]
, 2017 A distributed PLL-based frequency control is proposed in this paper for offshore wind turbine converters connected with diode-rectifier based high-voltage-direct-current (HVDC) systems. The proposed control enables a large number of wind turbines to work

How Changing Narratives About the Future Shape Policymaking for the Long Term
European Policy Analysis, EarlyView.ABSTRACT How can we explain decisions by governments to engage in policy investments—accepting short‐term costs in return for anticipated gains in the longer term—after previously sustaining the status quo? Our article examines the role of narratives in changing expectations about the future as a key driver of intertemporal policymaking. In light of an

European Policy Analysis, EarlyView.ABSTRACT How do governments' discursive credit‐claiming and blame‐deflection strategies shape perceived policy legitimacy in times of crisis? Despite the importance of legitimacy in conflictual times, systematic analyses of officeholders' credit‐claiming and blame‐deflection strategies and their effect on perceived legitimacy are still rare.

Epilepsia, EarlyView.Abstract The artificial intelligence (AI) revolution is upon us. It will inevitably form a central component of epilepsy workflows and patient advocacy. Therefore, it behooves us as health care providers to ride the crest of this wave and guide its direction for the benefit of all people with epilepsy.
