Clean energy is expected to enter a new stage of large-scale development along with the growing demand for building regional clean stations. However, as many stations comprise multiple different output characteristics and complementary coupling, potential these cannot be simply based on superposition outputs, this method lacks reasonable assessment results. This study proposes combining Grey re...

Racket’s syntax parameters support the hygienic implementation of syntactic forms that would otherwise introduce implicit identifiers unhygienically.

It is well known that every uniquely clean ring is strongly clean. In this paper, we investigate the question of when this result holds element-wise. We first construct an example showing that uniquely clean elements need not be strongly clean. However, in case every corner ring is clean the uniquely clean elements are strongly clean. Further, we classify the set of uniquely clean elements for ...
