Abstract A new generalized integral identity involving first order differentiable functions is obtained. Using this as an auxiliary result, we then obtain some refinements of Simpson type inequalities using a class called strongly ( s , m )-convex higher $$\sigma &gt;0$$ σ &gt; 0</mml:...

It is generally accepted that the first choice of treatment for spinal meningiomas is "radical" surgical removal.

In addition, there is no consensus on a surgical strategy for radicality, ...

Mammalian fossils from two principal collecting areas in the lower Hanna Formation of the Carbon Basin comprise three faunas, the Grayson Ridge, Halfway Hill, and Sand Creek faunas. The Grayson Ridge and Halfway Hill faunas are diverse, consisting cumulatively of 29 mammalian species, at least two of which are new. The faunas are approximately equivalent in age and are either latest lbrrejonian...
