We show that, for a stationary version of Hammersley’s process, with Poisson “sources” on the positive x-axis, and Poisson “sinks” on the positive y-axis, an isolated second class particle, located at the origin at time zero, moves asymptotically, with probability one, along the characteristic of a conservation equation for Hammersley’s process. This allows us to show that Hammersley’s process ...

Abstract Achievement of the United Nations Sustainable Development Goals (SDGs) is contingent on understanding potential interactions among human and natural systems. In Kenya, goal conserving expanding forest cover to achieve SDG 15 “Life Land” may be related other SDGs because it plays a role in regulating some aspects Kenyan precipitation. We present 40-yr analysis sources precipitation Keny...

Observations of the temporal and spatial distribution of N,.O in solution are not yet sufficient topermit quantitative assessment of the role of the ocean in the budget of atmospheric N,.O. Consideration of the global nitrogen cycle suggests hat the land should be the primary source of N20. The gas is removed in the atmosphere by photolysis and by reaction with O(•D), and there may be additiona...
