Abstract Negative impacts such as unstable power supply and stranded coal power assets caused by coal phase-out have frequently occurred.As an important regulatory measure to achieve the goal of carbon neutrality, whether carbon pricing can effectively deal with the negative impacts of coal phase-out has become a key issue of widespread Coffee Cup

ABSTRACT Marchantia emarginata Reinw., Blume & Nees, with nearly 30 assigned names, is considered the most taxonomically complex species in the family Marchantiaceae.Currently, this species is segregated into three subspecies, and this subspecific classification flavored-lube is widely accepted since its formal inception.However, due to its extensi

Abstract The strong cosmic censorship conjecture (SCCC) requires that spacetime cannot be extended beyond the Cauchy horizon.This ensures the predictability of spacetime.In this paper, we investigate the SCCC for a spherically symmetric charged de-Sitter black hole surrounded by dark matter using classical and quantum scalar fields.At the classical

The enigmatic animal phylum Placozoa holds a key position in the metazoan Tree of Life.A simple bauplan makes it appear to be the most basal metazoan known and genetic evidence also points to a position close to the last common metazoan ancestor.Trichoplax Coffee Cup adhaerens is the only formally described species in the phylum to date, making the

This paper presents a Accessories novel steering mechanism embedded in a point-the-bit rotary steerable system (RSS) for oilfield exploitation.The new steering mechanism adopts a set of universal joints to alleviate the high alternative strain on drilling mandrel and employs a specially designed planetary gear small tooth number difference (PGSTD)
