A transparent graphical user interface that overlays the user interfaces of other applications. The difference between the refractive index of the transparent resin and that of the scatterers is in the range of 0. Therefore, the access of the UE is achieved. Wing struts can also be removed from the emergency lateral ejection exit pathway by pneumatic or other explosive charge means. In some examples embodiments, a search assist system receives a query, such as a partial query, identifies two or more categories of data that include information satisfying the query, ranks the identified categories of data based on various selection criteria, and presents suggested search terms based on the rankings. Deflection and direction of the rotation axes for the rotation planes at selected levels of the ventricles are quantified and visualized.
