The permanent magnet brushless DC motor (BLDCM) is typically controlled using the six-step commutation method, and flux-weakening method employed to enable operate at speeds higher than base speed. Currently, it considered that weak magnetic angle range 0-pi/3, while for deep weakening pi/3-pi/2. In field-weakening control, a forward shift of point results in circulating current flowing three-p...

Interleukin 6 (IL-6) and insulin-like growth factor I (IGF-I) induce proliferative and antiapoptotic responses in multiple myeloma (MM) plasma cells. Because these cytokines may activate the phosphatidylinositol 3-kinase (PI 3-K)/AKT kinase pathway in other cell types, we investigated the role of PI 3-K/AKT in MM cell responses. IGF-I effectively activated PI 3-K in 8226 and OCI-My5 MM cells, b...

in this paper, at first we mention to some results related to pi and vertex co-pi indices and then we introduce the edge versions of co-pi indices. then, we obtain some properties about these new indices.

The branching ratio of the $K^+\to\pi^+e^+e^-e^+e^-$ ($K^+\to\pi^+4e$) decay is calculated at leading order in Standard Model. dominance neutral-pion pole determines overall to be $B(K^+\to\pi^+4e)=B(K^+\to\pi^+\pi^0)B(\pi^0\to4e)\approx7.0(3)\times10^{-6}$. significance this contribution very much concentrated context whole available phase space, throughout most which one-photon-exchange topol...
