Soft Artificial Ciliary Brush with Integrated Haptic Feedback for Efficient Airway Mucus Cleaning
Advanced Intelligent Systems, EarlyView.A fundamental mucus cleaning mechanism is reported, which utilizes both artificial cilia mechanical sweeping and suction‐based mucus cleaning. A novel haptic feedback interface for the artificial cilia provides touch feedback on tissue contact, enhancing operator control and safety.

Variation in Carbon Content During the Melting of γ-TiAl in a Graphite Crucible
CrystalsLiquid γ-TiAl alloy was prepared by vacuum induction melting within graphite crucibles, then cast using a centrifugal technique. In this process, the degree of superheat (ΔT)—defined as the temperature above the melting point—was carefully controlled ...

Microstructural Control and Alloy Design of the Ti-Al-Nb-W-B Alloys [PDF]
, 2008 The TiAl alloys have been considered as promising candidates for structural-materials applications at around 8000C. The major concern for the structural use of the TiAl alloys is their low ductility and poor fracture resistance at ambient temperature ...

A typology of schools across the four nations of the United Kingdom: Class, race and geography
British Educational Research Journal, EarlyView.Abstract In this paper we analyse the hierarchical field of schools across the United Kingdom during the transition to university and suggest that there are five socially distinct clusters of schools. Our five‐cluster typology of UK schools is composed of an established group of elite private and state schools, schools for the white rural and suburban ...
