4. Structural and Functional Properties of IL-4δ2, an Alternative Splice Variant of Human IL-4

Author

Vasiliev, A. M., Vasilenko, R. N., Kulikova, N. L., Andreev, S. M., Chikileva, I. O., Puchkova, G. Y., Kosarev, I. V., Khodyakova, A. V., Khlebnikov, V. S., Ptitsyn, L. R., Shcherbakov, G. Y., Uversky, V. N., DuBuske, L. M., and Abramov, V. M.

Abstract

Structural and functional properties of recombinant IL-4δ2, a naturally occurring splice variant of human IL-4 with a deletion of the loop region 22−37, have been analyzed. IL-4δ2 has α-helical structure and most likely preserves the “up−up−down−down” topology typical of the four-helix-bundle cytokines. IL-4δ2 interacts specifically with the α chain of IL-4R and competes effectively with IL-4 for the common binding sites. Thus, IL-4δ2 may act as a regulator of the cytokine net, being the natural antagonist of IL-4. Keywords: interleukin 4 • interleukine receptor • splice variant • cytokine • four-helix-bundle cytokine

5. Structural and Functional Properties of Yersinia pestis Caf1 Capsular Antigen and Their Possible Role in Fulminant Development of Primary Pneumonic Plague

Author

Abramov, V. M., Vasiliev, A. M., Khlebnikov, V. S., Vasilenko, R. N., Kulikova, N. L., Kosarev, I. V., Ishchenko, A. T., Gillespie, J. R., Millett, I. S., Fink, A. L., and Uversky, V. N.

Abstract

Yersinia pestis capsular antigen Caf1 is shown to be a β-structural protein that in polymeric form possesses very high conformational stability. Different approaches show that a dimer is the minimal cooperative block of Caf1 adhesin. Caf1 dimer interacts effectively with IL-1 receptors of human macrophage and epithelial cells. The specificity of such interaction is confirmed by the inhibition of IL-1α binding by Caf1. The Caf1 role in pneumonic plague pathogenesis is discussed. Keywords: bubonic plague • pneumonic plague • capsular antigen Caf1 • molecular adhesin • conformational stability

6. Atmospheric Disturbances and Radiation Impulses Caused by Large-Meteoroid Impacts on the Surface of Mars. II. Radiation Impulse Characteristics and Parameters of the Warm Layer

Author

Kosarev, I., Loseva, T., Nemtchinov, I., Shuvalov, V., and Greely, R.

Abstract

This paper presents the results of the calculation of spectral and angular characteristics of radiation emitted by the disturbed region after the vertical impacts on the Martian surface of stony meteoroids with radii R0from 1 to 100 m at speeds of 11–20 km/s. The time dependences are given for the density of the radiation flux incident on horizontal surface areas located at different distances from the impact point. For small impactors (R0= 1 m), the heating of the surface and surrounding gas by the radiation impulse from the hot region formed after the impact is insignificant even at the crater edge. However, the radiation impulse that heats up the surface is also emitted during the meteoroid flight through the atmosphere. Although this heating is insufficient to initiate evaporation, heat transfer by turbulent diffusion leads to the formation of a layer with temperatures that substantially exceed the initial temperature of the atmosphere. For large impactors (R0= 100 m), the total specific impulse of the plume radiation gives rise to the emergence of the heated layer with a thickness on the order of several meters within several kilometers of the impact point. The formation of this “warm” layer may lead to the formation of a high-speed jet moving along the Martian surface as well as eddies at the front of the precursor with a subsequent intense rise of dust.

7. Atmospheric Disturbances and Radiation Impulses Caused by Large-Meteoroid Impacts on the Surface of Mars. I. Formation and Evolution of Dust Cloud

Author

Kosarev, I., Losseva, T., Nemtchinov, I., Shuvalov, V., and Greeley, R.

Abstract

We consider the mechanisms of the formation of dust ejected from craters produced by large-meteoroid impacts on the Martian surface, as well as the mechanisms of the elevation of dust that already existed on the surface, due to impulsed aeolian processes. Detailed numerical calculations of the dust injection, the shock wave propagation, and the formation and evolution of the dust cloud are carried out for vertical impacts of meteoroids with sizes from 1 m to 100 m. The results of these calculations show that dust raised by a 1-m impactor is sufficient to produce a local dust storm, while the mass of dust formed in impacts of large bodies is comparable to the mass of a regional or even a global dust storm. The impact detection rates for 1-, 5-, 20-, and 100-m-sized meteoroids are estimated to be a few impact events per year, one event in every 5–6 years, one event in every 300–800 years, and one event in every 5000–20 000 years, respectively. In the last case, the thickness of the global layer of precipitated dust and small fragments, which has been formed through impacts over a period of 107–108years, is comparable to the thickness of the global dust layer on the Martian surface. In the first case, the mass of raised dust is greater than that for typical “dust devils.” The speed of impulsed wind at large distances from the impact site is shown to exceed the critical speed at which the blowing-off of dust from the surface begins. Some factors that may enhance the dust ejection have been previously ignored in numerical calculations. We discuss here the role of these factors. The second part of our study deals with the determination of the impact-induced radiation impulse and the estimation of its effect on the rise of dust.

Abstract

Abstract: Results from the multiplicity distributions of inclusive photons and charged particles, scaling of particle multiplicities, event-by-event multiplicity fluctuations, and charged-neutral fluctuations in 158A GeV Pb+Pb collisions are presented and discussed. A scaling of charged particle multiplicity as N part1.07±0.05 and photos as N part1.12±0.03 have been observed, indicating violation of naive wounded nucleon model. The analysis of localized charged-neutral fluctuation indicates a model-independent demonstration of non-statistical fluctuations in both charged particles and photons in limited azimuthal regions. However, no correlated charged-neutral fluctuations are observed.

9. Light Flashes Caused by Leonid Meteoroid Impacts on the Lunar Surface

Author

Artem'eva, N., Kosarev, I., Nemtchinov, I., Trubetskaya, I., and Shuvalov, V.

Abstract

In November 1999, light flashes were recorded on the Moon at the peak of the Leonid stream activity. It is likely that they were produced by the impacts of the stream particles on the lunar surface. In the present work the impacts of cometary particles are studied by solving a two-dimensional radiative-gasdynamic problem for particles of different sizes and densities; the flux of radiation of postimpact hot gas and plasma is calculated, and the luminous efficiencies are estimated, as are the sizes of the particles which could produce the observed flashes.

10. Evaluation of Light Flashes Caused by Impacts of Small Comets on the Surface of the Moon

Author

Artem'eva, N., Kosarev, I., Nemchinov, I., Trubetskaya, I., and Shuvalov, V.V.

Abstract

Images of the dayglow of the Earth's atmosphere in the ultraviolet wavelength region obtained by the photometer of the spacecraft Dynamics Explorerrevealed dark spots of the order of 50 km in diameter. These “atmospheric holes” were interpreted by the American physicist Frank as concentrations of water vapor formed as a result of the disintegration and vaporization of so-called small comets at high altitudes. An analysis of the same images showed that their explanation requires a frequency of comet collisions with the Earth as high as 20 events a minute! This sensational hypothesis evoked a heated scientific debate. The paper below contains an analysis of the possibility of observing Frank's hypothetical comets during their collisions with the Moon. By solving a two-dimensional radiative–gasdynamic problem, the authors demonstrate that the flashes occurring during such impacts can be observed from the Earth with ordinary telescopes.

Abstract

We have studied the azimuthal angle distributions of identified charged particles near mid-rapidity region in semi-central Pb+Pb collisions at SPS energies. Our preliminary results show that π mesons and protons seem to be emitted in the reaction plane, while out-of-plane for K mesons. This phenomenon might be explained by the existence of another possible effect such as in-medium potential as well as the collective motion.

Abstract

A search for baryonia with negative and positive strangeness decaying respectively into " and " has been carried out in a neutron beam with a mean momentum of ?40 GeV/c in an experiment performed at the Serpukhov accelerator. There is a strong indication of the existence of these baryonia. The following four charge states are observed for negative and positive strangeness: neutral, negative, positive and doubly charged. Their mean mass is 3055±25 MeV/c2 and the width G?36±15 MeV/c2. The data show that the isotopic spin of the baryonia is ?3/2. The baryonia production cross sections in the acceptable kinematic regionXF?0.2 andPT?1 GeV/c times the branching ratios of the observed decays are of the order of 1 µb per nucleon.

Abstract

The production of F-mesons on nuclear targets (carbon, aluminium and copper) by high-energy neutrons has been analysed. The dependence of the F-production cross section ratios on the nuclear mass numberA was parametrized by the power lawAa witha=0.81±0.06. Within the sensitive kinematic rangexF>0 andpT<1 GeV/c we have not observed any dependence of the exponenta on the longitudinal or transverse momentum. A possible interpretation of the measuredA-dependence is discussed in the Appendix.

Associated production off-mesons and strange particles by neutrons at energies of 30–70 GeV has been analysed. It has been found that at least 67% of inclusivef-meson production in the kinematic regionxF>0.1 andpT<1 GeV/c proceeds via OZI-allowed processes with extra strange particles. Doublef-meson production has also been observed and its cross section in the full kinematic region is estimated to be 15 ± 9µb.

Abstract

In this paper we present the results of a search for the charmed strange baryon Ξc+ in the final states Λ0π+π+K− and Ξ−π+π+. The experiment was performed using the magnetic spectrometer BIS-2 with a hydrogen target located in the neutron beam of the Serpukhov accelerator. A narrow peak in the Λ0π+π+K− state is observed at a mass of ≈2440 and possibly also of ≈2310 MeV/c2, corresponding to signals for the Ξc+ → Λ0π+π+K− and Ξc+ → Σ0π+π+K− (Σ0 → Λ0γ) decays respectively. The statistics obtained for the Ξ−π+π+ state is too low to make any conclusion.

Abstract

We present results of the exclusive diffractive reaction np ? ?0K0p at 0·08 < |t|< 0·53 GeV2/c2 and momenta between 30–70 GeV/c at the Serpukhov neutron beam. Thet-dependence is exp (Bt) withB= 11·4± 2·3 (GeV/c)-2 and it exhibits the diffractive minimum at ¦t¦ 0·28 GeV2/c2 for ?0K0 massesM < 1·8 GeV/c2.B decreases with increasingM. Correlation with the beam direction is observed in the rest frame of the ?0K0 system: the cross section rises for the forward-going ?0. The rise is more pronounced for higherM. The cross section of reaction np ? ?0K0p for 0<|t|< 0·53 GeV2/c2 is 10·3 ± 2·5 ± 2·8 µb.

Abstract

A signal of theΦ-K+K− decays has been observed in neutron-hydrogen interactions at energies of 30–70 GeV in an experiment using the BIS-2 spectrometer. The longitudinal momentum spectrum in the forward region,xF<0·1 atpT<1 GeV/c, can be well described by a power law dependence (1−xF)N withN=4·28±0·42. Thep

Abstract

An experiment on deep inelastic muon nucleon scattering in order to study the x-dependence of nucleon structure functions and their ratios over a range ofQ2=50–200 GeV2 andx= =0·4–2·0 is proposed. Such measurements performed on a number of nuclei with atomic weights from 2 to 207 provide new information for detailed studies of the EMC effect and test models explaining thex-behaviour of the nucleon structure functions and their ratios. The measurements are decisive for the proof that a quark-parton model of the nucleus describes adequately nuclear structure probed at high energies. The upgraded high luminosity BCDMS spectrometer with improved resolution in transferred energy? can be used for the measurements.

Abstract

In this paper we study the inclusive production of the charmed baryon Λc+ in interactions of 40–70 GeV/c neutrons with protons of hydrogen target. The experiment has been performed with the use of magnetic spectrometer BIS-2 located in the neutron beam of Serpukhov accelerator. The signal of Λc+ is observed in the effective mass spectra of Λ°π+π+π−. After the removal of interactions occurring on the container of liquid hydrogen, the signal consists of 14 combinations corresponding to ≈4 standard deviations of background. Its mean value is 2262 MeV/c2, width of the bin containing signal is 20 MeV/c2. On the basis of this signal we determine the value of cross section of Λc+ production times the branching ratio of its observed decay modeσ. Br (Λc+ → Λ°π+π+π−)=0·26±0·11 μb in the kinematic region ofxF>0·5 andpT<1 GeV/c.

34. Method of averaging the radiation transfer equations for a nonequilibrium plasma of plane geometry

Author

Kosarev, I. B.

Abstract

A method is presented for averaging the radiation transfer equations for a nonequilibrium plasma of plane geometry. The averaging of transfer difference equations is carried out separately for each spectral line and for groups of a continous spectrum. A difference scheme is obtained for one-sided radiation fluxes. Averaging coefficients are defined, characterizing absorption and emission of radiation by a cell of the difference scheme.

36. NMR study of 3He bubbles in phase-separated solid 3He –4He mixtures

Author

Kingsley, S., Kosarev, I., Roobol, L., Maidanov, V., Saunders, J., and Cowan, B.

Abstract

3He droplets embedded in a solid4He matrix have been studied by NMR and pressure measurements. One feature of the experiment is that the mixture crystals, of3He concentration 1%, are grown under constant pressure conditions to minimise the formation of defects. A number of sample pressures below 34 bar have been studied. Isotopic phase separation and the melting of the bubbles are clearly observed. Measurements ofT1,T2and magnetisation give detailed information on the structure of the droplets. At an initial sample pressure of 28.3 bar preliminary measurements of theT1of the liquid bubbles show a temperature dependence of the form(A+ B/T2)−1. This indicates that the expected relaxation in the liquid is augmented by a constant contribution, probably from the surface of the droplets.

Abstract

New data on the observation and study of a narrow resonance decaying intoS-(1,385)K+ have been obtained. The mass of the resonance is (1,956-6+8) MeV/c2, and its width is (27±15) MeV/c2. The resonance is produced in the diffraction dissociation of neutrons on quasi-free nucleons of carbon nuclei. The slope parameter of the differential cross section inPT2 is (9.9±3.0) (GeV/c)-2. The cross section times the branching ratio is (0.22±0.04) µb per nucleon. The resonance has one of the natural spinparities: 5/2+, 7/2- and so on.

Abstract

The first evidence of directed flow at 158 A GeV Pb + Pb collisions is observed using the Plastic Ball detector in WA98 experiment. The azimuthal angle of the total transverse energy, Φ0, is determined for each event using the observed protons in the Plastic Ball. A clear azimuthal asymmetry of fragments is observed with respect to Φ0. The degree of azimuthal asymmetry is found to be largest in mid-central collisions, which is consistent with the picture of the collective flow. The pt spectra of particles measured in the mid-rapidity spectrometer has been studied in conjunction with the Plastic Ball, and different pt slopes with respect to Φ0 for proton and π+ are observed.
