Future climate change is expected to affect ecosystem-atmosphere CO2 exchange, particularly through the influence of temperature. To date, however, few studies have shown that differences in the response of net ecosystem CO2 exchange (NEE) to temperature among ecosystems can be explained by differences in the photosynthetic and respiratory processes that compose NEE. Using a new nonparametric statistical model, we analyzed data from four forest ecosystems. We observed that differences among forests in their ability to assimilate CO2 as a function of temperature were attributable to consistent differences in the temperature dependence of photosynthesis and respiration. This observation …

Ecosystem CO2 exchange and atmosphere boundary layer (ABL) mixing are correlated diurnally and seasonally as they are both driven by solar insulation. Tracer transport models predict that these covariance signals produce a meridional gradient of annual mean CO2 concentration in the marine boundary layer that is half as strong as the signal produced by fossil fuel emissions. This rectifier effect is simulated by most global tracer transport models. However, observations to constrain the strength of these covariance signals in nature are lacking. We investigate the covariance between ecosystem carbon dioxide exchange and ABL dynamics by comparing one widely …

The Mutamathil Type Style: Towards Free, Technology-Friendly, Arabetic Types, Saad D. Abulhab
Publications and Research
Efforts to adapt various Arabetic scripts to the machine are as old as the field of typography. But most of these efforts concentrated primarily on forcing the machine to duplicate the Arabetic handwritten forms. Others have practically advocated divorce from the calligraphic tradition rather than enrichment and reform. One reason why the few modern attempts to typographically solve the technology-induced Arabetic script problems had failed is that many typeforms (or many times just theoretical calligraphy style) was presented as replacement for the traditional ones rather than as optional working types. New “controversial” types should be made widely available for users …
