Photon pair production at flavour factories with per mille accuracy
We present a high-precision QED calculation, with 0.1% theoretical accuracy, of two photon production in ee annihilation, as required by more and more accurate luminosity monitoring at flavour factories. The accuracy of the approach, which is based on the matching of exact next-to-leading order corrections with a QED Parton Shower algorithm, is demonstrated through a detailed analysis of the im...
متن کاملSoil organic carbon dynamics jointly controlled by climate, carbon inputs, soil properties and soil carbon fractions.
Soil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively. Using observations of SOC dynamics with detailed soil properties from 90 field trials at 28 sites under different agroecosystems across the Australian ...
متن کاملPorphyrin ‘‘Mille-Feuilles” photo-electrodes
A porphyrin ‘‘Mille-Feuilles” photo-electrode is fabricated layer-by-layer by deposition of anionic [zinc meso-tetrakis(p-sulfonato phenyl) porphyrin] (ZnTPPS ) and positively charged polypeptides on a 11-mercaptoundecanoic acid-modified gold electrode to form a photoactive film. This work demonstrates that it is possible to form 3D structures having regularly spaced layers of redox molecules. ...
متن کاملModeling organic carbon and carbon - mediated soil processes in DSSAT v 4 . 5
Cropping systems models have evolved over the last four decades in response to the demand for modeling to address more complex questions, including issues on sustainable production, climate change, and environmental impacts. Early models, which were used primarily for yield gap analysis, have increased in complexity to include not only nutrient and water deficiencies, but also pest and disease ...
