(Y=T×S×C×I) and the additive model is of the form Yt=Tt+St+Ct+It or (Y=T+S+C+I) The multiplicative model does not assume the independence of the four components T, S, C, and I of the time series, but the additive model is based on the assumption that four components are...
Gompertz: y = a + b c.x Lloyd–Lipow: y = a − b/x where y is the factor, x is time and a–c are model parameters. 1.5.4.3 Stochastic trajectory models The following models are the most commonly used. 1.5.4.3.1 Gamma process This is a stochastic process used to model deterior...
Our model draws together existing ideas in machine learning to suggest an explanation for the following key features of memory, only subsets of which are captured by previous models: 1. The initial encoding of memory requires only a single exposure to the event and depends on the HF, while th...
Lower-grade gliomas (LGGs) exhibit highly variable clinical behaviors, while classic histology characteristics cannot accurately reflect the authentic biological behaviors, clinical outcomes, and prognosis of LGGs. In this study, we carried out analyses
(x-axis) represented by each tissue (y-axis). The tissue types and component numbers are sorted for an optimal diagonal view. The numbers below thex-axis give the number of samples assigned to each component. The number of samples in each tissue is shown on the right side of the matrix...

The proposed framework consolidates earlier studies and puts forward three dimensions for a successful transition to omni-channel retailing BMs: a seamless customer experience, an integrated analytics system and an effective supply chain and logistics. Originality/value First, this paper applies a BM ...
CC[x]: Returns the complex conjugate ofx. If the optionCPVis set to0then it returnsx. A more detailed description of theseDsixToolsroutines can be found in Appendix D.1. OnceDsixToolsis loaded the user can already perform some basic operations. However, the real power ofDsixToolsresides ...
