Tau Propagation, Different Tau Phenotypes, and Prion-like Properties of Tau

Sanders et al. (2014) demonstrate in this issue of Neuron that the natively unfolded protein tau can propagate indefinitely in distinct stable strains, therefore supporting the general idea that tau has prion-like properties, with implications for Alzheimer’s disease and other tauopathies

Alternative Formulation of Classical Electrodynamics that Eliminates the Infinite Self-Energies of Point-Charges but Leaves their Motion and Interaction Unaffected

The theory of point-particles in classical electrodynamics has a well-known problem of infinite self-energy, and the same is true of quantum electrodynamics. Instead of concluding that there is no such thing as a true point-particle, it is shown here how to remove the infinities by supposing that the electromagnetic field tensor has a symmetric part. This does not change the physics, as the equation of motion and the antisymmetric part of the retarded fields appearing in the equation of motion are unaffected. The symmetric part of the field tensor is not observable and therefore it need not be gauge-invariant, whereas the antisymmetric part is observable, gauge-invariant, and satisfies both the Maxwell Equations and the field equations governing the whole field tensor. This approach goes well beyond prior efforts at classical renormalization, and also entails a new derivation of the Lorentz-Abraham-Dirac (LAD) equation of motion.Comment: 13 pages, no figures, miscellaneous minor improvements in response to comment

The Little Word Due

The Fifth and Fourteenth Amendments bar the government from depriving anyone of “life, liberty, or property, without due process of law.” The ambiguity of that phrase has kept the judiciary busy for many generations, but that same ambiguity has become “completely eclipsed by the little word ‘due.’” The goal of the present article is to study this critical word, and in particular to examine whether a process is automatically “due” if it is owed according to positive law, or alternatively whether a process can only be “due” if it accords with judicially ascertained principles of liberty and justice. The present article concludes that the latter interpretation is incorrect, and that the Due Process Clause should not be used to convert natural law into enforceable law outside the democratic and republican procedures established by the Constitution
