BackgroundPediatric solid tumor, the abnormal proliferation of solid tissues in children resulting in 2D Crystal Photo the formation of tumors, represent a prevailing malignant ailment among the younger population.Extensive literature highlights the inseparable association linking oral microbiome and adult tumors, but due to differences in age of o

Simultaneous multiple-fracture treatments in horizontal wellbores have become one of the key methods for economically and efficiently developing oil and gas resources in unconventional reservoirs.However, field data show that some perforation clusters have difficulty propagating fractures due to the internal mechanism of competing initiation and pr

Cookware Abstract We elaborate on various aspects of the conformal field theory of the symmetric orbifold.We collect various results that have appeared in the literature, and we present a coherent picture of the operator content of this CFT, relying on the orbifold extension of the Virasoro algebra.We then focus on the large N-limit of this theory,
