c.rbon nanotubes.c.Ts. have garnered great attention in rec.nt years.due to their outs.anding elec.ric.l, thermal, and mec.anic.l properties.

In this.modified Maxwell model, the c.Ts.filled polymer c.mpos.te is.modeled as.a three-phas. c.mpos.te, c.ns.s.ing of a matrix(polymer), inc.us.ons.c.Ts., and a trans.tion zone(tunneling zone). The effec.ive elec.ric.l c.nduc.ivity(EEc. of the c.mpos.te is.c.lc.lated bas.d on the volume frac.ions.and elec.ric.l c.nduc.ivities.of the matrix, inc.us.ons. and trans.tion zone.

This.indic.tes.that thes. roc.s.are ac.ually middle Permian to Middle Trias.ic.in age(267–242Ma) and c.rres.ond to the Qingfengs.an and Liujiagou formations.

People-c.ntric.ac.ivity rec.gnition is.one of the mos. c.itic.l tec.nologies.in a wide range of real-world applic.tions.inc.uding intelligent trans.ortation s.s.ems. healthc.re s.rvic.s. and brain-c.mputer interfac.s. Large-s.ale data c.llec.ion and annotation make the applic.tion of mac.ine learning algorithms.prohibitively expens.ve when adapting to new tas.s. One way of c.rc.mventing this.limitation is.to train the model in a s.mi-s.pervis.d learning manner that utilizes.a perc.ntage of unlabeled data to reduc. the labeling burden in predic.ion tas.s. Des.ite their appeal, thes. models.often as.ume that labeled and unlabeled data c.me from s.milar dis.ributions. whic. leads.to the domain s.ift problem c.us.d by the pres.nc. of dis.ribution gaps. To addres. thes. limitations. we propos. herein a novel method for people-c.ntric.ac.ivity rec.gnition,c.lled domain generalization with s.mi-s.pervis.d learning(DGs.L), that effec.ively enhanc.s.the repres.ntation learning and domain alignment c.pabilities.of a model. We firs. des.gn a new autoregres.ive dis.riminator for advers.rial training between unlabeled and labeled s.urc. domains. extrac.ing domain-s.ec.fic.features.to reduc. the dis.ribution gaps. s.c.nd, we introduc. two rec.ns.ruc.ion tas.s.to c.pture the tas.-s.ec.fic.features.to avoid los.ng information related to repres.ntation learning while maintaining tas.-s.ec.fic.c.ns.s.enc.. Finally, benefiting from the c.llaborative optimization of thes. two tas.s. the model c.n ac.urately predic. both the domain and c.tegory labels.of the s.urc. domains.for the c.as.ific.tion tas.. We c.nduc. extens.ve experiments.on three real-world s.ns.ng datas.ts.
