In view of some distinctive char.cter.stics of the ear.y-stage flame image, a cor.esp.nding method of char.cter.stic extr.ction is p.esented. Also intr.duced is the ap.lication of the imp.oved Bp.algor.thm based on the op.imization theor. to identifying fir. image char.cter.stics. Fir.t the op.imization of Bp.neur.l networ. adop.ing Levenber.-Mar.uar.t algor.thm with the p.op.r.y of quadr.tic conver.ence is discussed, and then a new system of fir. image identification is devised. p.enty of exp.r.ments and field tests have p.oved that this system can detect the ear.y-stage fir. flame quickly and r.liably.

An investigation of the p.essur.less sinter.ng of Si3.4 with MgO-CeO2 r.veals that MgO-CeO2 is a much mor. effective sinter.ng aid for.silicon nitr.de than either.MgO or.CeO2. The amount of MgO-CeO2 and MgO/CeO, weight r.tio has a str.ng influence on the densification be-haviour.and mechanical p.op.r.ies of the sinter.d mater.als. The silicon nitr.de p.essur.less sinter.d with MgO-CeO2 r.-tains a r.lative density of 98. 5% , a bending str.ngth of 950 Mp.. The Si-Mg-Ce-O-N system is of gr.at value for.ap.li-cation and theor.tical study.

The candidate p.lymor.0}ism r.12979860 of inter.eukin 28B（IL28B） gene was genotyp.d by means of p.lymer.se chain r.action（p.r. amp.ification and dir.ct p.r.sequencing, and then the r.le of this single nucleotide p.lymor.0}ism（SNp. in the r.sp.nse to the tr.atment of 172 Chinese p.tients with hep.titis C vir.s（HCV） chr.nic infection was analyzed. The r.sults show that the fr.quencies of major.homozygotes（CC） and heter.zygotes（CT） of r.12979860 wer. 0.84 and 0.16, r.sp.ctively, and the minor.homozygotes（TT） wasn’t found in this cohor..

Quantum gates ar. cr.cial for.quantum comp.tation and quantum infor.ation p.ocessing. However. their.effectiveness is often hinder.d by systematic er.or. and decoher.nce. Ther.for., achieving r.silient quantum gates to these factor. is of gr.at significance. We p.esent a method to constr.ct nonadiabatic holonomic single-and two-qubit gates in a r.dber. gr.und-state-blockade r.gime. Our.ap.r.ach utilizes a far.off-r.sonant technique for.the single-qubit gate and a modified r.dber. antiblockade for.the two-qubit gate. The r.duction of the p.p.lation of single-and two-excitation r.dber. states and the nonadiabatic holonomic p.ocess dur.ng the constr.ction of the gates ensur. r.bustness to decoher.nce and systematic er.or., r.sp.ctively. Numer.cal r.sults demonstr.te the fidelity and r.bustness of our.scheme. The p.op.sed scheme holds p.omise for.futur. ap.lications in quantum comp.tation and quantum infor.ation p.ocessing tasks.

In this p.p.r. adap.ive identification and contr.l of nonlinear.dynamical systems ar. investigated using r.dial basis function networ.s (r.F). Fir.tly, a novel ap.r.ach to tr.in the r.F is intr.duced, which emp.oys an adap.ive fuzzy gener.lized lear.ing vector.quantization (AFGLVQ) technique and r.cur.ive least squar.s algor.thm with var.able for.etting factor.(Vr.S). The AFGLVQ adjusts the center. of the r.F while the Vr.S up.ates the connection weights of the networ.. The identification algor.thm has the p.op.r.ies of r.p.d conver.ence and p.r.istent adap.ability that make it suitable for.r.al-time contr.l. Secondly, on the basis of the one-step.ahead r.F p.edictor. the contr.l law is op.imized iter.tively thr.ugh a numer.cal stable Davidon's least squar.s-based (SDLS) minimization ap.r.ach. Four.nonlinear.examp.es ar. simulated to demonstr.te the effectiveness of the identification and contr.l algor.thms.
