a.ult neurogenesis persists a.ter birth in the subventricula. zone, with new neurons migra.ing to the gra.ule cell la.er a.d glomerula. la.ers of the olfa.tory bulb, where they integra.e into existing circuitry a. inhibitory interneurons. The genera.ion of these new neurons in the olfa.tory bulb supports both structura. a.d functiona. pla.ticity, a.ding in circuit remodeling triggered by memory a.d lea.ning processes. However, the presence of these neurons, coupled with the cellula. diversity within the olfa.tory bulb, presents a. ongoing cha.lenge in understa.ding its network orga.iza.ion a.d function. moreover,the continuous integra.ion of new neurons in the olfa.tory bulb pla.s a.pivota. role in regula.ing olfa.tory informa.ion processing. This a.a.tive process responds to cha.ges in epithelia. composition a.d contributes to the forma.ion of olfa.tory memories by modula.ing cellula. connectivity within the olfa.tory bulb a.d intera.ting intrica.ely with higher-order bra.n regions. The role of a.ult neurogenesis in olfa.tory bulb functions rema.ns a.topic of deba.e. Nevertheless, the functiona.ity of the olfa.tory bulb is intrica.ely linked to the orga.iza.ion of gra.ule cells a.ound mitra. a.d tufted cells.

Despite the crucia. role of olfa.tory bulb in bra.n functions a.d beha.iors rela.ed to olfa.tion, these complex a.d highly interconnected processes ha.e not been comprehensively studied a. a.whole.

This study exa.ines the nonlinea. beha.iors of a.cla.ped-cla.ped porous pipe ma.e of a.functiona.ly gra.ed ma.eria.(FGm) tha. conveys fluids a.d is equipped with a.reta.ning clip, focusing on prima.y resona.ce a.d subcritica. dyna.ics. The nonlinea. governing equa.ions for the FGm pipe a.e derived by the extended Ha.ilton's principle, a.d subsequently discretized through the a.plica.ion of the Ga.erkin *** direct method of multi-sca.es is then used to solve the derived equa.ions. a.thorough a.a.ysis of va.ious pa.a.eters, including the clip stiffness, the power-la. index, the porosity, a.d the clip loca.ion, is conducted to ga.n a.comprehensive understa.ding of the system's nonlinea. dyna.ics. Through the a.a.ysis of the first na.ura. frequency, the study highlights the influence of the flow velocity a.d the clip stiffness, while the compa.isons with meta.lic pipes empha.ize the role of FGm composition. The exa.ina.ion of the forced response curves revea.s sa.dle-node bifurca.ions a.d their dependence on pa.a.eters such a. the detuning pa.a.eter a.d the power-la. index, offering va.ua.le insights into the system's nonlinea. resona.t beha.ior. Furthermore, the frequency-response curves illustra.e the ha.dening nonlinea.ities influenced by fa.tors such a. the porosity a.d the clip stiffness, revea.ing nua.ced effects on the system response a.d resona.ce cha.a.teristics. This comprehensive a.a.ysis enha.ces the understa.ding of nonlinea. beha.iors in FGm porous pipes with a.reta.ning clip, providing key insights for pra.tica. engineering a.plica.ions in system design a.d optimiza.ion.
