A note on the Bandwidth choice when the null hypothesis is semiparametric [PDF]

open access: yes
This work presents a tool for the additivity test. The additive model is widely used for parametric and semiparametric modeling of economic data. The additivity hypothesis is of interest because it is easy to interpret and produces reasonably fast ...

Deformation Behaviors in Single BCC‐Phase Refractory Multi‐Principal Element Alloys under Dynamic Conditions

open access: yesAdvanced Science, EarlyView.
Exceptional mechanical stability of refractory multi‐principal element alloy (RMPEA) across various strain‐rates and temperature is studied through multiscale experiments coupled with theoretical calculations. This stability originates from competition between twinning and adiabatic heating during dynamic deformation, contributed from severe lattice ...

Real‐Time Force Monitoring of Electrically Stimulated 3D‐Bioengineered Muscle Bioactuators Using Organic Sensors with Tunable Sensitivity

open access: yesAdvanced Intelligent Systems, EarlyView.
The integration of sensing elements in bioengineered actuators is key to obtain real‐time information about their performance and further control/automation. By coupling flexible organic field‐effect transistor to a skeletal muscle actuator we demonstrate the feasibility to record in real‐time its contractile behavior when stimulated by electrical ...
