Baby boomers will begin entering old age in 2011. They will be the largest and most diverse cohort ever to experience this life-course transition. The sheer number of baby boomers has challenged institutions time after time (Dychtwald, 1990). Despite extensive speculation regarding the political, economic, and social impact that the aging of baby boomers will have on American society, no one ha...

We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a dielectric (or magnetic moment) effect. We present a non-Abelian effective action for these gravitational waves with dielectric couplings and show that stable dielectric solutions exist. These solutions agree in the large...

We study almost complex structures on parallelizable manifolds via the rank of their Nijenhuis tensor. First, we show how computations such can be reduced to finding smooth functions underlying manifold solving a system first order PDEs. On specific manifolds, find an explicit solution. Then compute tensor curves structures, showing that there is no constraint (except for lower semi-continuity)...

Abstract We prove a general form of the regularity theorem for uniformity norms, and deduce an inverse these norms which holds class compact nilspaces including all abelian groups, also nilmanifolds; in particular we thus obtain first non-abelian versions such theorems. derive results from structure cubic couplings, thereby unifying with Host–Kra Ergodic Structure Theorem. A unification this ki...
