US nuclear power: Cancellations promise bleak year ahead

Year-ahead prediction of US landfalling hurricane numbers

We present a simple method for the year-ahead prediction of the number of hurricanes making landfall in the US. The method is based on averages of historical annual hurricane numbers, and we perform a backtesting study to find the length of averaging window that would have given the best predictions in the past.

Power Corrections and KLN Cancellations

We consider perturbative expansions in theories with an infrared cutoff λ. The infrared sensitive pieces are defined as terms nonanalytic in the infinitesimal λ2 and powers of this cutoff characterize the strength of these infrared contributions. It is argued that the sum over the initial and final degenerate ( as λ → 0) states which is required by the Kinoshita Lee Nauenberg theorem eliminates...

My research primarily uses close analysis of the dynamics of a group or semigroup action on a space to discern properties of the group or semigroup. In particular, I am primarily interested in groups of automorphisms of a space and in semigroups of endomorphisms of a space. Supporting this, I have a secondary focus on topological and symbolic dynamics, which itself has lead me to an interest in...
