In this paper, we introduce a family of two-dimensional group-V carbides with an ordered sequence tetragons and hexagons (th-$\mathrm{C}{X}_{2}$, where $X=\text{P}$, As, Sb). We demonstrate that th-$\mathrm{C}{X}_{2}$ monolayers exhibit robust energetic, dynamical, thermal, mechanical stability. Our calculations show the intrinsic structural anisotropy induces strongly anisotropic mechanical, e...

Let R be an o-minimal expansion of a group in language which Th(R) eliminates quantifiers, and let C predicate for valuational cut R. We identify condition that implies quantifier elimination Th(R,C) the expanded by small number constants, which, turn, is implied having being universally axiomatizable. The applies example case when convex subring field its residue o-minimal.

We find a peak in the goodness of fit at 11 years for the moving average. The fit between the two misery indices ...
