Micromagnetic study on the effect of circularity in hot-deformed Nd-Fe-B magnets [PDF]
AIP AdvancesIn general, the grain size in micromagnetic modeling for hot-deformed magnets is determined by the size of the c-plane and the aspect ratio, which cannot reflect the randomness of the grain shape. In this study, we consider, from a micromagnetic point of

The role of grain size distribution on magnetic properties of sintered Nd–Fe–B magnets [PDF]
AIP AdvancesThe influence of grain size distribution for sintered Nd–Fe–B magnets is investigated using computational micromagnetics. The standard deviation of grain size distribution is selected as a quantity that can measure an inhomogeneity in grain size ...

Listening to Hong Kong children's perspectives through pretend play
British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

A contra-linguistic study of negation in Korean and English
Studies in Logic, Grammar and Rhetoric, 2018 Negation is frequently found in every language, and many logicians or linguists have been carrying out research on it. Their investigations are, however, mostly confined to the languages of Europe.
