A part of the immune system that improves (complements) the ability of antibodies and phagocytic cells to clear microorganisms and injured cells from an organism, attacks the pathogen's cell membrane, and encourages inflammation called complement system. It is main part of immune system. Over thirty proteins and protein pieces compose the complement system, including cell membrane receptors, an...

A novel method is introduced for constructing two-dimensional (2D) surface meshes embedded in three-dimensional (3D) space time and 3D hypersurface four-dimensional (4D) time. In particular, we begin by dividing the space–time domain into slabs. Each slab equipped with an initial plane (hyperplane), conjunction unstructured simplicial (hypersurface) mesh that covers plane. We then obtain vertic...
