Conditional moments in nuclear fragmentation and liquid-gas phase transition in hot nuclei
The conditional moments of the charge distributions of the projectile fragments in sulphur fragmentation at 200 GeV/N are obtained using the simple Monte Carlo partition method. Thus, the logarithmic correlations between the conditional moments can be observed. The distributions of conditional moments are investigated. The results of the nuclear diffractive excitation, electromagnetic dissociation, and Monte Carlo methods are compared.

Particle production in Au–Au collisions at RHIC energies
Abstract An overlapping cylinder model (OCM) is introduced in this Letter which considers three components: the longitudinal flow, transverse flow and the temperature. A comparison of our model calculations in terms of pseudorapidity distributions with the most recent experiments is presented. To describe the experimental data at Relativistic Heavy Ion Collider (RHIC) energies ( s NN =130 and 200 GeV), a relative strong longitudinal flow and two partly overlapping cylinders are needed in the model. The difference between the different centrality events is described by the contribution of leading protons. The other parameter values do not depend on the centrality. The calculated results of the overlapping cylinder model are in agreement with the experimental data at the RHIC energies.

ANGULAR DISTRIBUTIONS OF TARGET BLACK FRAGMENTS IN NUCLEUS NUCLEUS COLLISIONS AT HIGH ENERGY
The experimental results of space, azimuthal, and projected angular distributions of target black fragments produced in silicon-emulsion collisions at 4.5A GeV/c (the Dubna energy) are reported. A multi-source ideal gas model is suggested to describe the experimental angular distributions. The Monte Carlo calculated results are in agreement with the experimental data.

Alpha emission in krypton–emulsion collisions at 1.7A GeV
Abstract The multiplicity and transverse momentum distributions of alpha projectile fragments emitted in nucleus–nucleus collisions at high energies are investigated. The results calculated by the two-source model are in agreement with the experimental data of krypton–emulsion collisions at 1.7 A  GeV.

Singly and Doubly Charged Projectile Fragments in Nucleus-Emulsion Collisions at Dubna Energy in the Framework of the Multi-Source Model *
The multiplicity distributions of projectile fragments emitted in interactions of different nuclei with emulsion are studied by using a multi-source model. Our calculated results show that the projectile fragments can be described by the model and each source contributes an exponential distribution. As the weighted sum of the folding result of many exponential distributions, a multi-component Erlang distribution is used to describe the experimental data. The relationship between the height (or width) of the distribution and the mass of the incident projectile, as well as the dependence of projectile fragments on target groups, are investigated too.

Higher moments of net baryon distribution as probes of the QCD critical point
It is crucially important to find an acceptance and late collision process independent observable in searching for the possible critical point predicted by QCD. By utilizing a multiphase transport (AMPT) model and ultrarelativistic quantum molecular dynamics (UrQMD) model, we study the centrality and evolution time dependence of higher moments of net baryon distribution in Au+Au collisions at sq root(s{sub NN})=17.3 GeV. The results suggest that kurtosis and skewness are less sensitive to the acceptance effect and late collision process. Thus, they should be good observables providing the information on the early stage of a heavy-ion collision. In addition, our study shows that the product of kurtosis times sigma{sup 2} of the net proton distribution is quite different from that of the net baryon distribution when the collision energy is lower than sq root(s{sub NN})=20 GeV, the Monte Carlo calculations on kurtosiscentre dotsigma{sup 2} have a deviation from the theoretical predictions.

On Descriptions of Particle Transverse Momentum Spectra in High Energy Collisions
The transverse momentum spectra obtained in the frame of an isotropic emission source are compared in terms of Tsallis, Boltzmann, Fermi-Dirac, and Bose-Einstein distributions and the Tsallis forms of the latter three standard distributions. It 
is obtained that, at a given set of parameters, the standard distributions show a narrower shape than their Tsallis forms which result in wide and/or multicomponent spectra with the Tsallis distribution in between. A comparison among the temperatures obtained from the distributions is made with a possible relation to the Boltzmann temperature. An example of the angular distributions of projectile fragments in nuclear collisions is given.

On Current Conversion between Particle Rapidity and Pseudorapidity Distributions in High Energy Collisions
In high energy collisions, one usually needs to give a conversion between the particle rapidity and pseudorapidity distributions. Currently, two equivalent conversion formulas are used in experimental and theoretical analyses. An investigation in the present work shows that the two conversions are incomplete. Then, we give a revision on the current conversion between the particle rapidity and pseudorapidity distributions.

The Wide-field Infrared Survey Explorer (WISE): Mission Description and Initial On-orbit Performance
The all sky surveys done by the Palomar Observatory Schmidt, the European Southern Observatory Schmidt, and 
the United Kingdom Schmidt, the InfraRed Astronomical Satellite, and the Two Micron All Sky Survey have 
proven to be extremely useful tools for astronomy with value that lasts for decades. The Wide-field Infrared 
Survey Explorer (WISE) is mapping the whole sky following its launch on 2009 December 14. WISE began 
surveying the sky on 2010 January 14 and completed its first full coverage of the sky on July 17. The survey 
will continue to cover the sky a second time until the cryogen is exhausted (anticipated in 2010 November). 
WISE is achieving 5σ point source sensitivities better than 0.08, 0.11, 1, and 6 mJy in unconfused regions on 
the ecliptic in bands centered at wavelengths of 3.4, 4.6, 12, and 22μm. Sensitivity improves toward the ecliptic 
poles due to denser coverage and lower zodiacal background. The angular resolution is 6".1, 6".4, 6".5, and 12".0 at 3.4, 4.6, 12, and 22μm, and the astrometric precision for high signal-to-noise sources is better than 0".15.

omega phi STATES IN CHIRAL QUARK MODEL
The omega phi states with spin S = 0, 1 and 2 are dynamically studied in a chiral SU(3) quark model by solving the resonating group method (RCM) equation. It is found that the interactions of omega phi systems are attractive, while no omega phi bound state or resonance state is obtained due to the insufficiency of the strength of omega phi attractions.
