Third or “Second and a Half”? Continuity, Path Dependence, and the Third Nuclear Age
Global Policy, EarlyView.ABSTRACT The world has entered a new nuclear age. Scholars have characterized this “third nuclear age” as one of renewed competition among nuclear‐armed great powers and the coming maturation of new technologies. I trace the origins of the new nuclear age. Focusing primarily on US strategies with two case studies on conventional strike capabilities and

Effective dispersal of fern spore and the ecological relevance of zoochory
Biological Reviews, EarlyView.ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Influence of point defect concentration on the generalized stacking‐fault energy in uranium dioxide
Journal of the American Ceramic Society, EarlyView.Abstract Stacking‐fault energy is a fundamental material property that significantly affects the shearability of crystalline materials by influencing the behavior of dislocations. Here, the impact of point defects on the stacking‐fault energy in UO2$\text{UO}_2$ nuclear fuel is investigated using a large‐set of molecular statics simulations combined to

Journal of Business Finance &Accounting, EarlyView.ABSTRACT We investigate investor perceptions of the US CEO pay ratio disclosure rule by studying market reactions to its implementation. Our findings reveal an overall negative market reaction, suggesting that investors anticipated the disclosure rule to be detrimental on average across firms.

Sleep neuroimaging: Review and future directions
Journal of Sleep Research, EarlyView.Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 646-662, March 2025.Abstract Samples of impactite from the small (~350 m diameter) Monturaqui crater in northern Chile contain Fe‐Ni metallic spherules sourced from the iron meteorite impactor. Textural characterization and quantification were done using SEM and μCT data. Two textural types are distinguished, with different size distributions.
