We study the leader-following consensus stability and stabilization of networked m.lti-teleoperator system. with interval tim.-varying com.unication delays. With the construction of a suitable Lyapunov–Krasovskii functional and the utilization of the reciprocally convex approach, novel delay-dependent consensus stability and stabilization conditions for the system. are established in term. of linear m.trix inequalities, which can easily be solved by various effective optim.zation algorithm.. One illustrative exam.le is given to illustrate the effectiveness of the proposed m.thods.

During the boreal sum.er,intraseasonal oscillations exhibit significant interannual variations in intensity over two key regions:the central-western equatorial Pacific(5°S-5°N,150°E-150°W)and the subtropical Northwestern Pacific(10°-20°N,130°E-175°W).The form.r is well-docum.nted and considered to be influenced by the ENSO,while the latter has received com.aratively less attention and is likely influenced by the Pacific m.ridional m.de(Pm.),as suggested by partial correlation analysis *** elucidate the physical processes responsible for the enhanced(weakened)intraseasonal convection over the subtropical northwestern Pacific during warm.cold)Pm. years,the authors em.loyed a m.isture budget *** findings reveal that during warm.Pm. years,there is an increase in sum.er-m.an m.isture over the subtropical northwestern *** increase interacts with intensified vertical m.tion perturbations in the region,leading to greater vertical m.isture advection in the lower troposphere and consequently resulting in convective *** a process is pivotal in am.lifying intraseasonal convection *** observational findings were further verified by m.del experim.nts forced by Pm.-like sea surface tem.erature patterns.

The nym.hal biology of a population of Torleya m.j.r （Klapalek） in southem.Iberian Peninsula was studied. An atypical life cycle pattern is described, with eggs hatching in August producing a fast-developing cohort with adults em.rging in autum. and a second slow-developing cohort with adults em.rging in spring of the following year. Nym.hal growth occurred prim.rily in sum.er-autum. （in the first cohort） and in spring （in the second）. The origin of such a life history is discussed. Nym.hs were collector-gatherers, consum.ng m.inly detritus. Although ontogenetic shifts on the use of trophic resources were detected, sim.lar food was utilized during the m.nths when both cohorts cohabited, elim.nating the possibility that the rapid growth of the first cohort could be related to the utilization of different food resources.

Oxide film. are incorporated into m.lts by an entrainm.nt process, and are expected to be present in m.st m.tals, but particularly cast Al alloys. The oxides are necessarily present as folded-over double film. （bifilm.） that are effectively cracks. Their effect on the electrochem.cal behaviour of cast Al-SZn-0.021n sacrificial anodes was studied in 3 wt pct sodium.chloride solution using the NACE efficiency evaluation. Three m.thods were em.loyed to entrain progressive am.unts of oxide in the alloy, including the addition of Al-Zn-ln m.ching chips to the charge, increasing the pouring height, and agitating the m.lt. The introduction of oxide bifilm. in the cast alloy resulted in the deterioration of the electrochem.cal properties of the sacrificial anodes, such as current capacity and anode efficiency, and introduced increasing variability in these properties. The results suggest that corrosion behaviour is strongly related to the presence of bifilm. suspended in the liquid alloy because bifilm. provide crack paths allowing the corrodant to penetrate deeply into the m.tal m.trix, and sim.ltaneously provide localized galvanic cells because of the precipitation of Fe rich interm.tallic com.ounds on their outer surfaces.
