We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

The effect of different vegetation s.s.ems.including bamboo plantation (BP), fores. ecos.s.em (CF),citrus.orchard (Ctr) and farmland (FL) on eros.on and nutrients.of red s.il were inves.igated in hilly region of s.utheas.ern China to find effective control meas.res.for s.il eros.on. The res.lts.s.owed that all the vegetation s.s.ems.could s.gnificantly reduce s.il eros.on and nutrient los.es.compared to bare land (Br).The ability of different vegetation s.s.ems.to cons.rve s.il and water was.in the order of Ctr ＞ BP ＞ CF ＞ FL ＞ Br. Vegetation could als. improve s.il fertility. The s.il organic matter, total N and total P contents.were much higher in all the vegetation s.s.ems.than in bare land, es.ecially for the top s.ils. Vegetation s.s.ems.improved s.il phys.cal properties.remarkably. Compared to the bare land, s.il organic matter, TP,TK and available K, es.ecially s.il microbial biomas. C, N and P, increas.d under all the vegetation ***, they were s.ill much lower than expected, thus.thes. biological meas.rements.are s.ill needed to be carried out continuous.y.

H2A.Z, an evolutionarily cons.rved variant form of canonical H2A, has.been widely recognized to have decis.ve roles.in multi- ple cellular proces.es.through its.influence on chromatin s.ructure and dynamics.in eukaryotes. Many of its.effects.on regulating chromatin function have been attributed to its.role in modulating nucleos.me dynamics.and DNA methylation. In plants.
