A single-pass high-gain x-ray free electron laser (FEL) calls for a high quality electron bunch.In particular, for a seeded FEL amplifier and for a harmonic generation beetroot birkenstock FEL, the electron bunch initial energy profile uniformity is crucial for generating an FEL with a narrow bandwidth.After the acceleration, compression, and trans
Abstract This work proposes the virtual restoration of the Bodhidharma polychrome sculpture from the Lingyan Temple in China.Based on scientific analyses and simulation experiments, exterior colours and textures were virtually restored by combining 3D scanning and multi-view 3D reconstruction.At the same time, an efficient cultural apple airpods se
Summary: Trypanosoma brucei evades mammalian immunity by using recombination to switch its surface-expressed variant surface glycoprotein (VSG), while ensuring that only one of many subtelomeric multigene VSG expression sites are transcribed at a time.DNA repair activities have been implicated in the catalysis of VSG switching by recombination, not
The market and demanding of lactic auto rosvin acid bacteria and their products keep increasingly in recent years.However, it is difficult to maintain the activity of lactic acid bacteria during the processing and storage periods due to the stress caused by heating and oxygen exposure conditions for these anaerobic and heat-sensitive bacteria.This
