ABSTRACT Supernumerary teeth are a developmental alteration in the number of teeth, commonly located in the maxilla and more frequent in males, in most cases, they are asymptomatic and can delay tooth eruption.Its etiology is still not well understood, and may be related to syndromic or nonsyndromic phenotypes, alterations in Cubicles the modulatio
This paper deals with a class of uncertain nonlinear impulsive switched systems with time-varying delays.A novel type of piecewise Lyapunov functionals is constructed to derive the exponential stability.This type of functionals can Water efficiently overcome the impulsive and switching BIRD jump of adjacent Lyapunov functionals at impulsive switchi
This study used the two-step floating catchment area method and potential model to calculate facility accessibility and potential service scope of public health infrastructure distribution, and to evaluate its spatial equity.We applied the Gini coefficient to measure the spatial equilibrium at each level of public health infrastructure in Doumen Di
