The uniaxial compressive strength of concrete: revisited

Materials and Structures
AbstractThis paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the commonly measured and adopted strength is ...

Perceived Educational Value of a Self‐Developed 3D‐Printed Pediatric Dentistry Simulator

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To design and assess a 3D‐printed pediatric dentistry simulator and to evaluate its perceived educational value and realism through student and expert feedback. Methods A maxillary simulator that is mountable on phantom heads was developed and produced by desktop stereolithography with single‐use inserts, enabling proximal caries ...

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...
