Electrical impedance is a critical parameter that characterises how materials and devices oppose the flow of alternating currents. This measure, which varies with frequency, is invaluable for probing ...

Continuous-time threshold autoregressive (CTAR) processes have been developed in the past few years for modelling non-linear time series observed at irregular intervals. Several approximating ...

The layered oxide material LiNiO 2 (LNO) is one of the most promising cathode materials for lithium-ion batteries (LIBs). However, the serious cation mixing of Ni 2+ and Li + in LNO cathode leads to ...
