The neurodegenerative disease Huntington’s Disease (HD) is caused by an expanded polyglutamine (polyQ) tract in the protein huntingtin (htt). Although the gene encoding htt was identified and cloned more than 15 years ago, and in spite of…
It is shown that solutions of the nonlinear Klein-Gordon equation utt - ∆u + mu + P'(u) = 0 decay to zero in the local L2 mean if the initial energy is bounded provided sP')s) - 2P(s) ≥ aP(s) ≥ 0 w.
Compactification entails changing a theory with respect to one of its space-time dimensions. Instead of this dimension ranging to infinity, the theory is changed so that this dimension has a finite range, and may be periodic.
