In the work,bean callus raised from a leaves of Bean common mosaic virus infected bean plant was obtained and adapted for the testing of antiviral activity of liposomal glycan-glycolipid *** adspersum glucans and Pseudomonas *** were constituents of liposomal *** has been shown that under the long-term cultivation(up to 3 months)in the presence of a liposomal preparation containing(10-100 mg/l),the virus is eliminated from the *** is evidenced by the absence of 391 bp sequence amplification product established by RT-PCR in the callus tissue,cultured on a medium containing the liposomal *** proposed model system is analogous to plant tumors and has obvious advantages over similar systems in vivo,since the callus growth is controlled and independent of environmental factors.

Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room *** with continuous-variable information encoding to nonclassical states,the distance for secure key transmission through lossy channels can approach 300 km in current optical *** protocols tolerate higher channel noise and also limited data processing efficiency compared to coherent-state *** secret key rate can be further increased by increasing the system clock rates,and,further,by a suitable frequency-mode-multiplexing of optical transmission ***,the multiplexed modes couple together in the source or any other part of the ***,multiplexed communication will experience cross talk and the gain can be ***,homodyne detectors allow solving this cross-talk problem by proper data *** is a potential advantage over protocols with single-photon detectors,which do not enable similar data processing *** demonstrate the positive outcome of this methodology on the experimentally characterized frequency-multiplexed entangled source of femtosecond optical pulses with natural cross talk between eight entangled pairs of *** the main result,we predict the almost 15-fold higher secret key *** experimental test and analysis of frequencymultiplexed entanglement source open the way for the field implementation of high-capacity quantum key distribution with continuous variables.
