You really need to understand your sources and do basic reraserch try to find out how reliable they are UncertainH.And thankfully becoming less obscure with each passing day. ...
A "Heisenberg, uncertainty, and the scanning tunneling microscope" paper with no mention of a extended election model.
A viable, working model of an extended electron would be a groundbreaking model published in an appropriate, well known, high impact journal. This is not the newish, obscure, low impact Frontiers of Physics.
Single author papers are dubious.
A preprint published in the condensed (solid) matter section.
Three (3) citations of the paper all including him as an author.
Thus: The paper is obviously invalid that it has been ignored for at least 8 years.
An irrelevant history/philosophy of physics "" preprint from Werner A Hofer.
An irrelevant review paper from a conference starts with the history of QM and has a bit of idiocy ("...it can be inferred that standard quantum mechanics, with its inherent uncertainties, is a model at the end of its natural lifetime.") by Werner A Hofer
