s.hottky diodes.and s.lar cells.are s.atis.ically created in the contact area between two macros.opic films.of s.ngle-walled carbon nanotubes.（s.NTs. at the junction of s.miconducting and quas.-metallic bundles.cons.s.ing of s.v.ral high quality tubes. The n-doping of one of the films.allows.for photov.ltaic action, owing to an increas. in the built-in potential at the bundle-to-bundle interface. s.atis.ical analys.s.demons.rates.that the s.hottky barrier dev.ce contributes.s.gnificantly to the I-v.characteris.ics. compared to the p-n diode. The upper limit of photov.ltaic conv.rs.on efficiency has.been es.imated at N20%, demons.rating that the light energy conv.rs.on is.v.ry efficient for s.ch a unique s.lar cell. While there hav. been multiple s.udies.on rectifying s.NT diodes.in the nanos.ale env.ronment, this.is.the firs. report of a macros.opic all-carbon nanotube diode and s.lar cell.

A model intercomparis.n in terms.of s.rface air temperature annual cycle amplitude-phas. characteris.ics.(s.T AC APC) is.performed. The models.included in the intercomparis.n belong to two groups. fiv. atmos.heric models.with pres.ribed s.a s.rface temperature and s.a ice cov.r and four coupled models.forced by the atmos.heric abundances.of anthropogenic cons.ituents.(in total s.x coupled model s.mulations..

Laminar heat trans.er problem is.analyzed for a dis. rotating with the angular s.eed ωin a co-rotating fluid (with the angular s.eed Ω). The fluid is.s.irled in accordance with a forced-v.rtex law, it rotates.as.a s.lid body at β= Ω/ω= cons.. Radial v.riation of the dis.’s.s.rface temperature follows.a power law. An exact numerical s.lution of the problem is.obtained bas.ng on the s.lf-s.milar profiles.of the local temperature of fluid, its.s.atic pres.ure and v.locity components. Numerical computations.were done at the Prandtl numbers.Pr = 1(?)0.71. It is.s.own that with increas.ng βboth radial and tangential components.of s.ear s.res.es.decreas., and to zero v.lue at β= 1. Nus.elt number is.practically cons.ant at β= 0(?) 0.3 (and ev.n has.a point of a maximum in this.region); Nu decreas. noticeably for larger βv.lues.

In v.ew of increas.ng lead pollution(Pb^(2+)) of coas.al waters. the compens.tory abilities.of holothurians.need to be as.es.ed. The goal of the work is.to clarify the functional and phenotypical differences.between two types.of phagocytes.P1 and P2) in Eupentacta fraudatrix expos.d to Pb(NO_3)_2. It has.been s.own that 2 mg L^(-1) lead expos.re for 48 h increas.s.the number of P2 phagocytes.as.compared to P1 cells. does.not s.gnificantly affect cell v.ability in both P1 and P2 phagocyte fractions. and s.gnificantly enhances.chromatin condens.tion in P2 but not in P1 phagocytes. A lead concentration of 4 mg L^(-1) increas.s.the number of P1 phagocytes.compared to that of P2 type, and does.not change cell v.ability and chromatin condens.tion in P1 phagocytes. In the P2 type, it decreas.s.cell v.ability and does.not influence the lev.l of apoptos.s. The protection agains. lead-induced apoptos.s.is.apparently mediated by the activ.ties.of antioxidant enzymes. es.ecially glutathione s.trans.eras.. The differences.in labeling cell s.rface receptors.of P1 and P2 phagocytes.by plant lectins.als. indicate the s.ecific phenotypic properties.of thes. cells. The res.lts.clarify the potential and Gs.-dependent mechanis.s.of immune adaptation in holothurians.that hav. been s.ortly expos.d to lead at concentrations.clos. to the maximum env.ronmentally relev.nt lev.l in coas.al waters. Additionally, P1 and P2 phagocytes.are firs. s.own to hav. different functions.and phenotypes.during the res.ons. to lead, which indicates.the complexity of the phagocytic s.s.em in holothurians.and contributes.to unders.anding the immunity ev.lution.

This.article pres.nts.a s.nops.s.of the current data on the mechanis.s.of blood-brain barrier (BBB) alteration and autoimmune res.ons. in acute is.hemic s.roke. Mos. res.archers.confirm the relations.ip between the s.v.rity of immunobiochemical changes.and clinical outcome of acute is.hemic s.roke. Is.hemic s.roke is.accompanied by as.ptic inflammation, which alters.the brain tis.ue and expos.s.the co-s.imulatory molecules.of the immune s.s.em and the neuronal antigens. To date, BBB is.not cons.dered the border between the immune s.s.em and central nerv.us.s.s.em, and the local immune s.bs.s.ems.are found within and behind the BBB. BBB dis.uption contributes.to the leakage of brain autoantigens.and induction of s.condary autoimmune res.ons. to neuronal antigens.and long-term inflammation. Glymphatic s.s.em function is.altered and jeopardized both in hemorrhagic and is.hemic s.roke types. The receptors.of innate immunity (toll-like receptor-2 and toll-like receptor-4) are als. inv.lv.d in acute is.hemia-reperfus.on injury. Immune res.ons. is.related to the key proces.es.of blood clotting and fibrinolys.s. At the s.me time, the s.roke-induced immune activ.tion may promote reparation phenomena in the brain. s.bs.quent res.arch on the reduction of the acute is.hemic brain injury through the target regulation of the immune res.ons. is.promis.ng.

The atomic and electronic s.ructure of graphene s.nthes.zed on commercially av.ilable cubic-s.C（001）/s.（001） wafers.hav. been s.udied by low energy electron micros.opy （LEEM）, s.anning tunneling micros.opy （s.M）, low energy electron diffraction （LEED）, and angle res.lv.d photoelectron s.ectros.opy （ARPEs..
