niosomes, non-ionic surfactant vesicles (nsvs), are the hydrated lipids composed mainly of different classes of non-ionic surfactants, introduced in the seventies as a cosmetic vehicle. nowadays, niosomes are used as important new drug delivery systems by many research groups and also they are effective immunoadjuvants which some commercial forms are available in the market. these vesicles rece...

In this paper, we investigate the delay-dependent robust stability of fuzzy Cohen-Grossberg neural networks with Markovian jumping parameter and mixed time varying delays by delay decomposition method. A new Lyapunov-Krasovskii functional (LKF) is constructed by nonuniformly dividing discrete delay interval into multiple subinterval, and choosing proper functionals with different weighting matr...

Czap and Jendrol’ introduced the notions of strong parity vertex coloring and the corresponding strong parity chromatic number χs. They conjectured that there is a constant bound K on χs for the class of 2-connected plane graphs. We prove that the conjecture is true with K = 97, even with an added restriction to proper colorings. Next, we provide simple examples showing that the sharp bound is ...
