Crisis, temporality and governmental policy agendas: The cases of Finland and Sweden
Scandinavian Political Studies, EarlyView.Abstract Crises transform the temporal orientation of political decision‐making. They demand immediate and decisive action and thus convert time into a means of political control. In these circumstances, assessing the long‐term consequences of proposed policies with respect to welfare, sustainability or justice also becomes demanding.

Artificial Organs, EarlyView.This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

A calculation method of thermal deformation for double helical gear
, 2019 Thermal deformation caused by gear transmission is an important factor causing gear impact, vibration and partial load. Gear modification can effectively improve the effects caused by thermal deformation.

Understanding excessive sleep in people with psychotic disorders
British Journal of Clinical Psychology, EarlyView.Abstract Background There has been increasing attention to sleep disturbances such as insomnia in psychosis, due to its impact on symptoms, well‐being, and recovery. However, excessive sleep and extended sleep duration are common in psychosis (partly linked to sedating antipsychotic medication) and have been relatively neglected, despite plausible ...
