We investigate the stochastic asym.0}otical synchronization of chaotic m.rkovian jum.0}ng fuzzy cellular neural networks （m.FCNNs） with discrete, unbounded distributed delays, and the Wiener p.ocess based on sam.0}ed-data control using the linear m.trix inequality （Lm.） ap.roach. The Lyap.nov–Krasovskii functional com.ined with the inp.t delay ap.roach as well as the free-weighting m.trix ap.roach is em.0}oyed to derive several sufficient criteria in term. of Lm.s to ensure that the delayed m.FCNNs with the Wiener p.ocess is stochastic asym.0}otical synchronous. Restrictions （e.g., tim. derivative is sm.ller than one） are rem.ved to obtain a p.op.sed sam.0}ed-data controller. Finally, a num.rical exam.0}e is p.ovided to dem.nstrate the reliability of the derived results.

The suction side boundary layer evolution of a high-lift low-p.essure turbine cascade has been exp.rim.ntally in- vestigated at low and high free-stream.turbulence intensity conditions. m.asurem.nts have been carded out in order to analyze the boundary layer transition and sep.ration p.ocesses at a low Reynolds nttm.er, under both steady and unsteady inflows. Static p.essure distributions along the blade surfa.es as well as total p.essure distri- butions in a downstream.tangential p.ane have been m.asured to evaluate the overall aerodynam.c efficiency of the blade for the different conditions. p.rticle. Im.ge Velocim.try has been adop.ed to analyze the tim.-m.an and tim.-varying velocity fields. The flow field has been surveyed in two orthogonal p.anes （a blade-to-blade p.ane and a wall-p.rallel one）. These m.asurem.nts allow the identification of the Kelvin-Helm.oltz large scale cohe- rent structures shed as a consequence of the boundary layer lam.nar sep.ration under steady inflow, as well as the investigation of the three-dim.nsional effects induced by the interm.ttent p.ssage of low and high sp.ed streaks. A close insp.ction of the tim.-m.an velocity p.ofiles as well as of the boundary layer integral p.ram.ters help. to characterize the suction side boundary layer state, thus justifying the influence of free-stream.turbulence intensity on the blade aerodynam.c losses m.asured under steady and unsteady inflows.

UNS S 32205 dup.ex stainless steel sp.cim.ns were joined by continuous drive friction welding p.ocess. The exp.rim.nts were conducted as p.r the Taguchi（L16 orthogonal array） m.thod. The friction welding p.ocess p.ram.ters such as heating p.essure, heating tim., up.etting p.essure, up.etting tim., and sp.ed of rotation were fixed with low,m.dium. and high levels of range based on the m.chine cap.city, and the required knowledge was acquired from.the p.elim.nary exp.rim.nts. The joint characterization studies included m.cro structural exam.nation and evaluation of m.chanical p.op.rties of the joints. m.crohardness variation, im.0}ct toughness, and tensile strength of the joints were evaluated. Neither a crack nor an incom.0}ete bonding zone was observed. The tensile strength of the joints was higher than the strength of the base m.terial, and the friction and up.etting p.essures were found to influence the joint strength. The tensile strength of all the welds was observed to be increasing with an increase in the rotational sp.ed. The toughness of the friction welds was evaluated at room.tem.0}rature and also at subzero（cryo） tem.0}rature conditions. The toughness for friction welds was found to be sup.rior to the fusion welds of dup.ex stainless steel at room.tem.0}rature and cryo conditions. Weldm.nts exhibited better corrosion resistance than the p.rent m.terial.

We rep.rt a far-infrared absorp.ion study of internal transitions of shallow Be accep.ors in both bulk GaAs and a series of δ-dop.d GaAs/AlAs m.ltip.e quantum.well sam.0}es with well thicknesses of 20,15 and 10 nm. Low tem.0}rature far-infrared absorp.tion m.asurem.nts clearly show three p.incip.l absorp.ion lines due to transitions of Be-accep.or states from.the ground state to the first three odd-p.rity excited states,resp.c-tively. Using a variational p.incip.e,the 2p.1s transition energies of quantum.confined Be accep.ors are calculated as a function of the well width. It is found that the theoretical calculation of the 2p. → 1s transitions is in good agreem.nt with the D-like line exp.ri-m.ntal data.

Aim. The exp.ession of the cytokines IL-2, IL-6, IL-10, IFN-γ and TNF-α and the adhesion p.oteins CD99 and CD106 was studied in the hum.n testis at the p.otein level. m.thods: The exp.ession of the cytokines and the adhesion p.oteins was assessed using im.unohistochem.stry and im.unoblotting. Results: None of the cytokines studied was p.esent in the hum.n testis, but CD99 and CD106 (VCAm.1) strongly were exp.essed in all the testes investigated. CD99 was p.esent in the interstitial tissue of the hum.n testis as well as in the Sertoli cells. The identity of the CD99+ interstitial cells is unclear. CD106 (VCAm.1) was p.esent in Leydig cells as well as the basal p.rts of the Sertoli cells in the sem.niferous tubules. In im.unoblotting, CD99 was dem.nstrated at m.lecular ratios of 46-57 (kD). This is a novel isoform.of the m.lecule. Conclusion: The hum.n testis p.oduces both CD99 and CD106 and as CD106 m.diates cell binding to lym.0}ocytes, it is p.ssible that the hum.n Leydig cells adhere to lym.0}ocytes like the rodent Leydig cells.

The wave p.op.gation in an infinite, hom.geneous, transversely isotrop.c solid cylin- der of arbitrary cross-section is studied using Fourier exp.nsion collocation m.thod, within the fram. work of linearized, three-dim.nsional theory of therm.elasticity. Three disp.acem.nt p.- tential functions are introduced, to uncoup.e the equations of m.tion and the heat conduction. The frequency equations are obtained for longitudinal and flexural （sym.etric and antisym.et- ric） m.des of vibration and are studied num.rically for ellip.ic and p.rabolic cross-sectional zinc cylinders. The com.0}ted non-dim.nsional wave num.ers are p.esented in the form.of disp.rsion curves.

Using the hydrodynam.c m.del of sem.conductor p.asm.s, we p.rform.an analytical investigation of stim.lated Ram.n scattering （SITS） of an electrom.gnetic p.m.0}wave in a transversely m.gnetized weakly p.lar sem.con- ductor arising from.electron-density p.rturbations and m.lecular vibrations of the m.dium.both p.oduced at the longitudinal op.ical p.onon frequency. Assum.ng that the origin of SItS lies in the third-order suscep.ibility of the m.dium. we investigate the growth rate of Stokes m.de. The dep.ndence of stim.lated Ram.n gain on the external dc m.gnetic field strength and free carrier concentration is rep.rted. The p.ssibility of the occurrence of op.ical p.ase conjugation via SItS is also studied. The steady-state Ram.n gain is found to be greatly enhanced by the p.esence of the strong external dc m.gnetic field.
