The paper is a bit more accomplished than you suggest. I am not sure how much, though. For instance the "bosonic electrons" seems to refer to an arrangement of multiple electrons (held together in some fashion that I don't understand) that can have multiple vibrational modes that can superimpose. It is these states that are bosonic. All of this might be right or wrong on a deeper level but not on the "oxymoron" level you are talking about.
electrons are point-like particles not toroid shaped currents and electron size can be measured down to 3x10^-18cm as written in this very well written CERN document

On the Mirage of the Classical Electron of Uhlenbeck and Goudsmit
"The idea that the electron is an extended charged object the spinning of which is responsible for its magnetic moment is shown to require a sizable portion of the electron to spin at speeds very close to the speed of light, and in fact to explode within an unacceptably short time, ~1E-31 s. The experimentally well-established magnetic moment of elementary particles such as the electron therefore must be accepted as an intrinsic property, with no need for classical models based on spatially extended objects. Emphasizing these facts in education, as early as possible, is important to the framing of the proper mind-set."
Moreover, how can be "bit more accomplished" a paper that blatantly contradicts the widely studied and accepted, 100 years old, special relativity?
Electrons moving at light speed ? Really ?
