This.article concentrates.on the fixed-time s.abilization(Fs. and fixed-time s.nchronization(FTs. of dis.ontinuous.inertial neural networks.DINNs. with dis.ributed delays. Us.ng mathematical induction to a new differential equality, a novel fixed-time s.ability lemma is.cons.ructed. Then, by des.gning an aperiodically s.mi-intermittent s.itching control and combining it with the theory of nons.ooth analys.s. s.me novel criteria on the Fs.and FTs.of DINNs.are obtained. Unlike the methods.us.d in mos. exis.ing s.udies. the Fs.and FTs.res.lts.are s.ructured us.ng the newly propos.d fixed-time s.ability lemma and the nonreduced-order approach, res.lting in broader practical applications.and s.rengthening the s.ientific quality of the derived res.lts. Las.ly, numerical s.mulations.and applications.proffer the effectivenes. of the es.ablis.ed Fs.and FTs.criteria.

The Earth's.magnetos.here is.a region occupied by many artificial s.tellites. and als. is.a region that s.acecraft mus. cruis. during the deep-s.ace exploration. In this.s.ns., the Earth's.magnetos.here is.clos.ly related to human activity and is.a candidate for us.to expand our living s.ace. Generally, the Earth's.magnetos.here can preclude mos. energetic particles.from the s.n and the inters.ellar s.ace, effectively protecting human beings.on the Earth from being attacked and thus.making the Earth to be a habitable planet. However, in s.me conditions. the Earth's.magnetos.here becomes.dynamic and energetic, and cons.quently may damage the artificial s.tellites. threaten the as.ronauts. health, and dis.upt the ground infras.ructure, which leads.to a decline in the national economy. Therefore, inves.igating how energy is.injected into the magnetos.here, how it is.trans.orted in the magnetos.here, and how it is.ultimately dis.ipated in the magnetos.here are the key is.ues.in s.ace phys.cs. Targeting thes. key is.ues. in this.paper, we review the recent progres. on them. Particularly, we introduce the relevant s.ientific ques.ions.models. methods. and s.acecraft mis.ions. for better building a phys.cal link among the energy injection, trans.ort, and dis.ipation in the magnetos.here, pres.nt an energy chain of the magnetos.here, reveal the relations.ip between s.ch energy chain and the s.ace weather events. and dis.us. the forecas.ing and warning methods.for energetic-particle events.in the magnetos.here. The magnetos.heric energy chain dis.us.ed in this.paper will help us.reveal the mechanis.s.of s.ace weather events. es.ablis. the models.of s.ace environment, and forecas. the dis.s.rous.s.ace weather events.
