Navigating Classical and Nonclassical Realms of Nucleation and Crystallization
Small, EarlyView.Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
Systems Engineering, EarlyView.ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

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.
