A comprehensive embryonic staging series of the turtle Trachemys scripta
Developmental Dynamics, EarlyView.Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

An analytical method to predict efficiency of aircraft gearboxes [PDF]
A spur gear efficiency prediction method previously developed by the authors was extended to include power loss of planetary gearsets. A friction coefficient model was developed for MIL-L-7808 oil based on disc machine data. This combined with the recent

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change
European Policy Analysis, EarlyView.ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
