Proteorhodopsin——A new path for biological utilization of light energy in the sea

The sea is the cradle of photosynthesis on the Earth. Bio-utilization of light in the sea is usually thought to be carried out by light-harvesting pigments, such as normal chlorophyll, divinyl chlorophyll and bacterial chlorophyll, which exist correspondi…     

A Monte Carlo study on the production scale and internal structure of jets in high energy collisions

The production scale and internal structure of jets produced in high energy collisions were studied using Jetset and Herwig Monte Carlo generators. Two scales were found. One is the jet-development scale, which determines the size of the jet developed from a mother-parton. The other is the jet-production scale with which the jets produced are the most consistent with QCD jet-production dynamics and will provide the most reliable dynamical information about their mother-partons.
