In this paper, we investigate the Sherman-Morrison-Woodbury formula for {1}-inverses and {2}-inverses of bounded linear operators on a Hilbert space. Some conditions are established to guarantee that (A+YGZ*)? = A? ?A?Y(G? +Z*A?Y)?Z*A? holds, where stands any kind standard inverse, {1}-inverse, {2}-inverse, Moore-Penrose Drazin group core inverse dual A.

This article constructs examples of associative submanifolds in $G_2$-manifolds obtained by resolving $G_2$-orbifolds using Joyce's generalised Kummer construction. As the approach $G_2$-orbifolds, volume tends to zero. partially verifies a prediction due Halverson and Morrison.

T hroughout life, stem cells maintain themselves by dividing to produce one or two daughter stem cells with an identical developmental potential. Although this self-renewal process is fundamental to all types of stem cells, the precise mechanism varies between different tissues and stages of development. Sean Morrison examines the self-renewal of different types of stem cells to understand how ...

Effective instructional design is a major prerequisite for desired learning outcomes. Even though the field of instructional design (ID) is relatively young, its multidisciplinary and rapidly evolving nature requires meticulous work to implement the most current evidence-based heuristics in instructional settings. The sixth edition of Designing Effective Instruction by G. R. Morrison, S. M. Ros...
