Background: With the development of advanced characterization techniques, lithium-ion battery non-linearities have recently gained increased attention which can benefit health diagnosis and ageing mechanism identification. In comparison to conventional single sine wave-based methods, multisine-based non-linear method has advantage capturing dynamic voltage response within a short testing durati...

Following the discovery of the cosmic microwave background, the hot big-bang model has become the standard cosmological model. In this theory, small primordial fluctuations are subsequently amplified by gravity to form the large-scale structure seen today. Different theories for unified models of particle physics, lead to different predictions for the statistical properties of the primordial fl...
