چکیده
We construct a class of projected SO~5! models where the Gutzwiller constraint of no-double-occupancy is implemented exactly. We introduce the concept of projected SO~5! symmetry where all static correlation functions are exactly SO~5! symmetric and discuss the signature of the projected SO~5! symmetry in dynamical correlation functions. We show that this class of projected SO~5! models can give a realistic description of the global phase diagram of the high-Tc superconductors and account for many of their physical properties. @S0163-1829~99!12241-0#

Supercritical Fluid Extraction of Carotenoid from Microalgae with Projected Thermodynamic Models (RESEARCH NOTE)
In this study, two thermodynamic models (regular solution theory and equation of state) were applied to obtain carotenoid solubility in the supercritical carbon dioxide solvent. Theoretical data obtained from the models were compared with the experimental data extracted from a published paper. The use of equation of state as an empirical correlation for collating and predicting liquidliquid and...
متن کاملClimate change scenarios generated by using GCM outputs and statistical downscaling in an arid region
Two statistical downscaling models, the non-homogeneous hidden Markov model (NHMM) and the Statistical Down–Scaling Model (SDSM) were used to generate future scenarios of both mean and extremes in the Tarim River basin,which were based on nine combined scenarios including three general circulation models (GCMs) (CSIRO30, ECHAM5,and GFDL21) predictor sets and three special report on emission sce...
متن کاملLarge-scale Inversion of Magnetic Data Using Golub-Kahan Bidiagonalization with Truncated Generalized Cross Validation for Regularization Parameter Estimation
In this paper a fast method for large-scale sparse inversion of magnetic data is considered. The L1-norm stabilizer is used to generate models with sharp and distinct interfaces. To deal with the non-linearity introduced by the L1-norm, a model-space iteratively reweighted least squares algorithm is used. The original model matrix is factorized using the Golub-Kahan bidiagonalization that proje...
متن کاملMechanisms Maintaining Southern Ocean Meridional Heat Transport under Projected Wind Forcing
Meridional heat transport (MHT) in the Southern Ocean (SO) and its components are analyzed with two eddy-permitting climate models. The two models present a consistent picture of the MHT response to projected twenty-first-century changes in SO winds. In agreement with a recent analysis based on an ocean data synthesis product, much of the MHT in the SO is found to be due to the time-mean fields...
متن کاملGlobular clusters within 5 ◦ of the Galactic center ?
In the recent years we have concentrated efforts to collect Colour-Magnitude Diagrams of the globular clusters projected in the central parts of the Galaxy. So far we were able to gather photometric data in the V, I and Gunn z bandpasses, for 16 out of the 17 known clusters in the central 5◦ radius, most of them severely reddened. Reddening, distance and metallicity are estimated from the horiz...
