This is a constant though, and a constant can be zero. Therefore, SES can be said to be equivalent to an ARIMA (0,1,1) model without a constant (i.e. θ_0 = 0), where α = 1 - θ_1. Hope this helps!

Genetic structural variants (SVs), especially those leading to gene fusions, are well-known oncogenic drivers. These SVs can produce overexpression or loss-of-function of certain genes, or generate chimeric fusion proteins.
