In this paper‎, ‎making use of a new identity‎, ‎we establish new‎ ‎inequalities of Ostrowski type for the class of preinvex functions and‎ ‎gave some midpoint type inequalities‎.

The C++ language currently does not provide a mechanism for an object to determine its type at runtime. We propose the Dossier class as a standard interface for accessing type information from within a C++ program. We have implemented a tool called mkdossier that automatically generates type information in a form that can be compiled and linked with an application. In the prototype implementati...

‎For the subclasses $mathcal{M}_1$ and $mathcal{M}_2$ of‎ ‎monomorphisms in a concrete category $mathcal{C}$‎, ‎if $mathcal‎{M}_2subseteq mathcal{M}_1$‎, ‎then $mathcal{M}_1$-injectivity‎ ‎implies $mathcal{M}_2$-injectivity‎. ‎The Baer type criterion is about‎ ‎the converse of this fact‎. ‎In this paper‎, ‎we apply injectivity to the classes of $C$-dense‎, ‎$C$-closed‎ ‎monomorphisms‎. ‎The con...

The title compound, neodymium sesquiselenide, is isotypic with the other known rare-earth metal(III) selenides M(2)Se(3) (M = La-Pr and Sm-Lu) with the cubic C-type structure. It adopts a cation-defective Th(3)P(4)-type arrangement with close to 8/9 of the unique neodymium-cation site occupied, leading to the composition Nd(2.667)Se(4) (Z = 4) or Nd(2)Se(3) (Z = 5.333), respectively. The Nd(3+)...
