Life is evolving fast (at least in the first world) and the latest technological gadget becomes outdated even before we have learnt how to use it. In this respect, science is no exception. The new buzzword ‘Systems Biology’ entered the vocabulary of the scientific community only a few years ago. Now that every biologist is aware of it and almost everyone seems to be doing it, an even newer buzz...

SHA1 is the representative reservoir in Liao He Basin. Through the introduction of curvature displayed on the gray scale, we determine the substructure and fractures. Geostatistical inversion method is used to help study the porosity of reservoir. The relationship between interval transit times and resistivity among mudstone and sandstone, before and after water injection, is analyzed. The rela...

We calculate the critical exponents of the chiral phase transition at nonzero temperature using the thermal and chiral susceptibilities. We show that within a class of confining Dyson–Schwinger equation (DSE) models the transition is mean field, and that an accurate determination of the critical exponents requires extremely small values of the current-quark mass, several order of magnitude smal...

We use a complete sample of RR Lyrae stars discovered by the Quasar Equatorial Survey Team survey using light curves to design selection criteria based on Sloan Digital Sky Survey (SDSS) colors. Thanks to the sensitivity of the u g color to surface gravity and of the g r color to effective temperature and to the small photometric errors ( 0.02 mag) delivered by SDSS, RR Lyrae stars can be effic...
