Size Distributions of Atmospheric Aerosol Compositions in Saitama, Japan

A survey of atmospheric aerosols in a suburban area near Tokyo, Japan was conducted using an Andersen sampler. Significant amounts of Na and Cl collected were considered to be derived from sea salt. The difference between the Na/Clratio in the area and that in sea salt indicated a considerable loss of Cl. This is assumed to be caused by the formation of NaNO3, which is one of the main nitrate s...

Totality in arena games

We tackle the problem of preservation of totality by composition in arena games. We first explain how this problem reduces to a finiteness theorem on what we call pointer structures, similar to the parity pointer functions of Harmer, Hyland & Melliès and the interaction sequences of Coquand. We discuss how this theorem relates to normalization of linear head reduction in simply-typed λ-calculus...
