These time series may pro.id. valuable info.matio. abo.t the und.rlying d.namics. It has been suggested.that co.plex d.namic systems, ranging fro. eco.ystems to.financial markets and.the climate, pro.0}ce generic early-warning signals at the ＂tipping po.nts,＂ where they anno.nce a sud.en shift to.ard.a d.fferent d.namical regime, such as a po.ulatio. extinctio., a systemic market crash, o. abrupt shifts in the weather. o. the o.her hand. the framewo.k o.

As a particular example, the quasispecies mo.0}l suggests that RNA viruses self-o.ganize their mutatio. rate near the erro.-catastro.he thresho.d. where ro.ustness and.evo.vability are balanced.in such a way that survival is o.timized.

Its mixture with silty o. clayey so.l is used.as a co.ting to.reinfo.ce the walls o. raw earth co.structio.s which are very sensitive to.water.

The heavy fuel o.l was mixed.with a silty-clayey so.l, in d.fferent pro.o.tio.s, and.water to.make bricks samples o. which tests were carried.o.t. At the end.o. the experimental tests, it appears that the water co.tent increases grad.ally, but no. significantly with the ad.itio. o. heavy fuel o.l, which causes a slight increase in the speed.o. heat pro.agatio. thro.gh the material with red.ced.po.o.ity, particularly tho.e co.taining higher quantities o. heavy fuel o.l. Co.versely, we no.e a go.d.perfo.mance o. heavy fuel o.l in terms o. water resistance pro.erties such as po.o.ity accessible by water and.ero.0}bility.
