Time-resolved soft-x-ray-diffraction experiments give access to microscopic processes in a broad range of solid-state materials by probing ultrafast dynamics of ordering phenomena. While laboratory-based high-harmonic generation (HHG) light sources provide the required photon energies, their limited photon flux is distributed over a wide spectral range, rendering typical monochromatic diffraction schemes challenging. Here, we present a scheme for energy-dispersive soft-x-ray diffraction with femtosecond temporal resolution and photon energies across the water window from 200 to 600 eV.

Much less is known about the psychological processes that occur when people grapple with self-control conflicts and that may contribute to successful goal pursuit. Influenced by the neighboring fields of emotion regulation and coping, self-regulatory flexibility has been identified as one of such potential processes.

Background: Specifically, we propose that because some forms of self-control involve denying oneself hedonic pleasures, it may lead to negative affect. Because people may then prioritize emotion regulation over self-control, negative affect may in turn lead to emotion regulation efforts, specifically the use of emotion regulation strategies, and an increased likelihood of self-control failure.
