Differen.ial scan.in. calorimetric （DSC） study was carried out at differen. heatin. rates to examin. the solid state reaction. in.a 7150 A1-Zn.Mg alloy in.water-quen.hed （WQ） state, n.turally an. artificially aged tempers. The exothermic an. en.othermic peaks of the thermograms in.icatin. the solid state reaction.sequen.e were iden.ified. The shift of peak temperatures to higher temperatures with in.reasin. heatin. rates suggests that the solid state reaction. are thermally activated an. kin.tically con.rolled. The artificial agin. behaviour of the alloy was assessed by measurin. the variation. of hardn.ss with agin. time. The fraction.of tran.formation.（Y）, the rate of tran.formation.（dY/dt）, the tran.formation.fun.tion.lY）, an. the kin.tic parameters such as activation.en.rgy （Q） an. frequen.y factor （k0） of all the solid state reaction. in.the alloy were determin.d by an.lyzin. the DSC data, i.e. heat flow in.olved with the correspon.in. DSC peaks. It was foun. that the kin.tic parameters of the solid state reaction. are in.good agreemen. with the published data.

n.-methyladen.sin.(m^(6)A), the most prevalen. an. con.erved Rn. modification.in.eukaryotic cells, profoun.ly in.luen.es virtually all aspects of mRn. metabolism. mRn. plays crucial roles in.n.ural stem cell gen.sis an. n.ural regen.ration. where it is highly con.en.rated an. actively in.olved in.these processes. Chan.es in.m^(6)A modification.levels an. the expression.levels of related en.ymatic protein. can.lead to n.urological dysfun.tion.an. con.ribute to the developmen. of n.urological diseases. Furthermore, the proliferation.an. differen.iation.of n.ural stem cells, as well as n.rve regen.ration. are in.imately lin.ed to memory fun.tion.an. n.urodegen.rative diseases. This paper presen.s a comprehen.ive review of the roles of m^(6)A in.n.ural stem cell proliferation. differen.iation. an. self-ren.wal, as well as its implication. in.memory an. n.urodegen.rative diseases. m^(6)A has demon.trated divergen. effects on.the proliferation.an. differen.iation.of n.ural stem cells. These observed con.radiction. may arise from the time-specific n.ture of m^(6)A an. its differen.ial impact on.n.ural stem cells across various stages of developmen.. Similarly, the diverse effects of m^(6)A on.distin.t types of memory could be attributed to the in.olvemen. of specific brain.region. in.memory formation.an. recall. In.on.isten.ies in.m^(6)A levels across differen. models of n.urodegen.rative disease, particularly Alzheimer's disease an.

The proposed framework con.ists of disaggregate activity-based represen.ation.of travel choices of in.ividual motorists on.the deman. side in.egrated with disaggregate dyn.mic modelin. of n.twork performan.e, through vehicle-based traffic simulation.models on.the supply side.
