Question about code location for "Lithium-ion battery performance model including solvent segregation effects"

Hi PyBaMM team,  

I'm looking for the code implementation related to the paper:  
"Lithium-ion battery performance model including solvent segregation effects"（DOI: arxiv-2311.05467）

Could you please indicate where this model (specifically the solvent segregation and degradation coupling implementations) is located in the PyBaMM repository?  

Thank you for your help!
