A construction of hexagon relations—algebraic realizations four-dimensional Pachner moves—is proposed. It goes in terms “permitted colorings” 3-faces pentachora (4-simplices), and its main feature is that the set permitted colorings nonconstant—varies from pentachoron to pentachoron. Further, a cohomology theory formulated for these relations, nontriviality demonstrated on explicit examples.

Abstract Mucin-1 (MUC-1) is associated with a broad range of human epithelia including gastric, lung and colorectal. In this work, direct competitive electrochemical immunosensor based on gelatin modified transduction platform was designed. Dopamine (DA)/mucin-1 functionalized electro-active carbon nanotubes were employed as signal generating probes in the construction for early stage diagnosis...
