On May 18, 2013, at the annual meeting of the American Psychiatric Association in San Francisco, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2013) was, with intense anticipation, released. When I arrived the day earlier, I immediately encountered three men protesting peacefully on the sidewalk outside of my hotel: One sign re...

We are interested in catalysts consisting either of substitutionally doped oxides (e.g. RuxCe1-xO2) or of submonolayers of an oxide supported on another oxide (e.g. VOx supported on ceria). Calculations and experiments show that in most cases these systems are more active catalysts than the original oxide (i.e. ceria). We use theory to try to find general patterns governing the activation by do...

In this paper, we investigate the generalized Hyers-Ulam stability of Jordan homomorphisms in Jordan Banach algebras for the functional equation begin{align*} sum_{k=2}^n sum_{i_1=2}^ksum_{i_2=i_{1}+1}^{k+1}cdotssum_{i_n-k+1=i_{n-k}+1}^n fleft(sum_{i=1,i not=i_{1},cdots ,i_{n-k+1}}^n x_{i}-sum_{r=1}^{n-k+1} x_{i_{r}}right) + fleft(sum_{i=1}^{n}x_{i}right)-2^{n-1} f(x_{1}) =0, end{align*} where ...
