Zebrafish ventral gastrula fate map reveals neural crest progenitor domain
Developmental Dynamics, EarlyView.Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Energy Science &Engineering, EarlyView.1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...
