Abstract: In this paper, the problem of global mu-stability for quaternion-valued neural networks with time-varying delays and unbounded distributed delays is investigated. To avoid the non-commutativity of quaternion multiplication, the quaternion-valued neural networks is decomposed into two complex-valued systems. By employing the homomorphic mapping principle, a sufficient condition for the existence and uniqueness of equilibrium point of the considered quaternion-valued neural networks is proposed in the form of linear matrix inequality (LMI) in complex-valued domain. Further, the appropriate Lyapunov-Krasovkii functional is constructed in the Hermitian quadratic form, and sufficient condition to ensure the global mu-stability of the equilibrium point is obtained by using inequality technique. Finally, two numerical examples with simulations are provided to verify the effectiveness of the obtained results. (c) 2018 Elsevier B.V. All rights reserved.

Abstract: Organic heat insulating materials with low density and low thermal conductivity have been widely used in building and domestic appliances. However, their highly flammable and poorly flexible characteristics hamper the application under certain circumstances. In this work, novel nanocomposite paper with low thermal conductivity, flame retardancy and good mechanical property was prepared by employing ultralong hydroxyapatite (HAP) nanowires as scaffolds for silica aerogels. The conductivity of the HAP/silica aerogel nanocomposite paper at room temperature decreased from 0.056 to 0.045 Wm(-1) K-1 as the amounts of silica aerogels increased from 0 to 50 wt%, indicating the excellent heat insulating performance. Meanwhile, the prepared paper showed remarkable flame retardancy with the peak heat release rate (HRR) of only 33.1 W/g when silica aerogel content was 50 wt%. Thermal stability analysis showed that the weight losses of all the nanocomposite papers with different contents of silica aerogels were
