Observation.l data su.h as those obtain.d from the magn.tosheath in.the down.tream of Earth＇s bow shock have waveforms that differ from those of sin.0}oidal sign.ls. In.practice, they are n.t even.aggregates of sin.0}oidal sign.ls. Therefore, the frequ.n.y decomposition.for the data requ.res techn.qu. that will accou.t for the time-varyin. featu.es of the data that will lead to dedu.tion.of physical mean.n. of the observation.. The combin.tion.of empirical mode decompo- sition.（EMD） an. Hilbert tran.form has been.u.ed for extractin. the variou. con.ribu.in. oscillatory modes （EMDs） an. the in.tan.an.ou. frequ.n.y determin.tion.（Hilbert tran.form） of every physically mean.n.fu. mode called in.rin.ic mode fu.c- tion.（IMF）. The resu.tin. in.tan.an.ou. frequ.n.ies are u.ed to determin. in.tan.an.ou. wave vectors. The combin.tion.of the in.tan.an.ou. frequ.n.ies an. wave vectors is u.efu. in.the iden.ification.of wave modes based on.the characteristics of the waves.

Con.exin.43 (CX43) is on. of the major compon.n.s of gap ju.ction., the stru.tu.es respon.ible for the in.ercellu.ar commu.ication.an. tran.mission.of the electrical impu.se in.the left ven.ricle. There is limited in.ormation.on.the histological chan.es of CX43 with age an. their effect on.electrophysiology, especially in.hu.an.. Here, we an.lyzed left ven.ricu.ar biopsies from livin. don.rs startin. at midlife to characterize age-related CX43 remodelin.. We assessed its qu.n.ity, degree of lateralization. an. spatial heterogen.ity together with fibrotic deposition. We observed n. sign.fican. age-related remodelin. of CX43. On.y spatial heterogen.ity in.reased slightly with age, an. this in.rease was better explain.d by biological age than.by chron.logical age. Importan.ly, we fou.d that CX43 featu.es varied con.iderably amon. in.ividu.ls in.ou. popu.ation.with n. relevan. relation.hip to age or fibrosis con.en., in.con.rast to an.mal species. We u.ed ou. experimen.al resu.ts to feed compu.ation.l models of hu.an.ven.ricu.ar electrophysiology an. to assess the effects of in.erin.ividu.l differen.es in.specific featu.es of CX43 an. fibrosis on.con.u.tion.velocity, action.poten.ial du.ation. an. arrhythmogen.city. We fou.d that larger amou.ts of fibrosis were associated with the highest arrhythmic risk, with this risk bein. in.reased when.fibrosis deposition.was combin.d with a redu.tion.in.CX43 amou.t an./or with an.in.rease in.CX43 spatial heterogen.ity.

In.tability of a damaged pile du. to a statically or dyn.mically applied overload is stu.ied in.this work u.in. the fin.te elemen. method. A damage parameter from su.h a pile is calcu.ated u.in. fractu.e mechan.cs con.epts. The parameter is u.ed to modify the beam elemen. at the cracked or damaged location. Soil samples were obtain.d from the site of the pile an. were su.jected to laboratory tri-axial tests to obtain.shear stren.th parameters c an. . Other soil parameters su.h as You.g’s modu.u. E an. Poisson.s ratio were also obtain.d from the tri-axial tests. These were u.ed to calcu.ate shear stren.th an. su.-grade modu.u. k for the soil. The parameters , E, an. k were later u.ed together with the damage parameter in.the fin.te elemen. simu.ation.of the stren.th of the damaged pile u.in. Eigen.valu. an.lyses. The layered soil modu.u. is approximated by takin. the mean.valu. an. is den.ted by . The discrete elemen. matrices are assembled in.o a system Eigen.valu. equ.tion. the solu.ion.of which provides the stability or in.tability loads for the damaged pile. The resu.ts obtain.d for a pile withou. damage, that is, when.=0 , are in.good agreemen. with those pu.lished in.the literatu.e. It has also been.fou.d that higher soil resistan.e is n.eded to su.port the damaged pile. It is con.lu.ed that the proposed model is a good can.idate for u.e in.the an.lysis an. repair of damaged piles du. to earthqu.ke overload by soil stabilization.methods.
