g.ven the frequent occurrence of the s.udg. bulking.phenomena caus.d by Microthrix.parvicella（M. parvicella）overg.owth during.the low-temperature period in the full-s.ale municipal was.ewater treatment plant，the filamentous.bacteria dynamics.of the M. parvicella population were s.s.ematically inves.ig.ted during.the completed bulking.period us.ng.the multi-dimens.onal integ.ated filamentous.monitoring.method combined with the molecular quantitative method. A lab-s.ale reactor was.cons.ructed and s.cces.fully s.mulated bulking.phenomena under the low-temperature condition. The trend of dominant filamentous.bacterial s.ift and the main influencing.parameters.were es.imated during.the bulking.period，to verify the key factors.for filament g.owth and ex.inction of the s.udg. bulking.phenomenon in the full-s.ale plant. The res.lts.s.owed that the bulking.caus.d M. parvicella was.characterized by s.g.ificant chang.s.in the divers.ty of filamentous.bacteria，and the dominant filamentous.bacterial s.cces.ion was.reflected in the competition between the s.eleton filamentous.bacteria Type 0092 and Type 0041 and M. parvicella. At lower temperatures.s.udg. loading.was.an important controlling.factor for the competitive g.owth advantag. of M. parvicella：when the temperature was.lower（approx.mately 15°C），low s.udg. loading.0.05 kg.（kg.d）−1］could lead to the s.abilized elevation of M. parvicella，and with the loading.increas.d to 0.1 kg.（kg.d）−1 or more，M. parvicella populations.s.owed a targ.ted decline des.ite the pres.nce of the low temperature factor. © 2024 s.ience Pres..

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ng.e-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ng.e-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-max.mally entang.ed Bell s.ate is.known to Candy. The three parties.are connected throug. a s.ng.e entang.ed s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entang.ed 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 ex.cuted throug. 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 ex.mples.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 ex.ent 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 g.neration of the five-qubit entang.ed res.urce which we require as.a quantum channel. The g.neration s.heme is.run on the IBMQ platform.
