Scaling in athletic world records
Article Abstract:
Two scaling laws with a breakpoint of around 150 seconds to 170 seconds can be used to describe the mean speed in running races as a function of race time. This is interpreted as being the transition time between anaerobic and aerobic energy expenditure by athletes. It is possible to use the slopes of the two scaling laws as a test to assess how evolved and how close to the limit performances are for athletes who vary in age, gender or country of origin. The smaller the scaling exponents, the better the performance in longer races.

Spurious trends in satellite MSU temperatures from merging different satellite records
Article Abstract:
The current years have been among the warmest based on the global surface air temperature records however the global annual mean surface warming rate of 0.13 C per decade is different from the global lower-tropospheric cooling trend which is measured by the satellite Microwave Sounder Unit(MSU). Different MSU sea surface temperatures, retrievals and equivalent temperatures from an atmospheric model. Two spurious downward trend was noted in the MSU-2R record which coincides with satellite changes.

Scaling and criticality in a stochastic multi-agent model of a financial market
Article Abstract:
Financial prices show some universal characteristics resembling scaling laws characterizing physical systems, where several units interact. An explanation that scaling in finance emerges from the interactions of many market participants contradicts the prevalent efficient market hypothesis. A multi-agent model of financial markets is described, supporting the concept that scaling is due to mutual interactions of participants.
