Se. stabilization is one.of the.e.se.tial proble.s in e.gine.ring syste.s, and se.f-trigge.e. control(STC) can save.the.storage.space.for inte.active.information, and can be.succe.sfully applie. in ne.worke. control syste.s with limite. communication re.ource.. In this study, the.se. stabilization proble. and STC de.ign of Boole.n control ne.works are.inve.tigate. via the.se.i-te.sor product te.hnique. On the.one.hand, the.large.t control invariant subse. is calculate. in te.ms of the.strongly conne.te. compone.ts of the.state.transition graph, by which a graph-the.re.ical condition for se. stabilization is de.ive.. On the.othe. hand, a characte.istic function is e.ploite. to de.e.mine.the.trigge.ing me.hanism and fe.sible.controls. Base. on this, the.minimum-time.and minimum-trigge.ing ope.-loop, state.fe.dback and output-fe.dback STCs for se. stabilization are.de.igne.,re.pe.tive.y. As classic applications of se.f-trigge.e. se. stabilization, se.f-trigge.e. synchronization, se.f-trigge.e. output tracking and se.f-trigge.e. output re.ulation are.discusse. as we.l. Additionally, se.e.al practical e.ample. are.give. to illustrate.the.e.fe.tive.e.s of the.re.ical re.ults.

Survival analysis is a fundame.tal tool in me.ical scie.ce.for time.to-e.e.t data. Howe.e., its application to colony organisms like.be.s pose. challe.ge. due.to the.r social nature.

This study e.aluate. the.pe.formance.of se.i-parame.ric share. frailty mode.s (gamma, inve.se.normal, and positive.stable.in comparison to the.traditional Cox mode. using be.s’ survival data). We.e.amine. the.e.fe.t of misspe.ification of the.frailty distribution on re.re.sion and he.e.oge.e.ty parame.e.s using simulation and conclude. that the.he.e.oge.e.ty parame.e. was more.se.sitive.to misspe.ification of the.frailty distribution and choice.of initial parame.e.s (cluste. size.and true.he.e.oge.e.ty parame.e.) compare. to the.re.re.sion parame.e..

Classical survival analysis assume. all subje.ts will e.pe.ie.ce.the.e.e.t of inte.e.t, but in some.case., a portion of the.population may ne.e. e.counte. the.e.e.t. The.e.survival me.hods furthe. assume.inde.e.de.t survival time., which is not valid for hone. be.s, which live.in ne.ts. The.study introduce. a se.i-parame.ric marginal proportional hazards mixture.cure.(PHMC) mode. with e.change.ble.corre.ation structure. using ge.e.alize. e.timating e.uations for survival data analysis. The.mode. was te.te. on cluste.e. right-ce.sore. be.s survival data with a cure. fraction, whe.e.two be. spe.ie. we.e.subje.te. to diffe.e.t e.tomopathoge.s to te.t the.e.fe.t of the.e.tomopathoge.s on the.survival of the.be. spe.ie.. The.e.pe.tation-Solution algorithm is use. to e.timate.the.parame.e.s. The.study note. a we.k positive.association be.we.n cure.statuse.

The.Cox-Sne.l re.iduals show that the.propose. se.iparame.ric PH mode. ge.e.ally fits the.data we.l as compare. to mode. that assume.inde.e.de.t corre.ation structure. Thus, the.se.i parame.ric marginal proportional hazards mixture.cure.is parsimonious mode. for corre.ate. be.s survival data.
