We discuss aspects of the statistical hadronization model for the production of mesons with open and hidden charm in ultra-relativistic nuclear collisions. Emphasis is placed on what can be inferred from the dependence of the yield of charmonia on the number of participants in the collisions.

A statistical procedure is described for estimation of unknown parameters (constants) in a complex computer model from an observational or experimental data base. The approach provides accuracy assessments of the estimates. An application is given to a computer code which models nuclear fusion reactors.

Systems theory of Smad signalling Clarke et al 2 Abstract Transforming Growth Factor-β (TGFβ) signalling is an important regulator of cellular growth and differentiation. The principal intracellular mediators of TGFβ signalling are the Smad proteins, which upon TGFβ stimulation accumulate in the nucleus and regulate transcription of target genes. To investigate the mechanisms of Smad nuclear ac...

Transforming growth factor-beta (TGFbeta) signalling is an important regulator of cellular growth and differentiation. The principal intracellular mediators of TGFbeta signalling are the Smad proteins, which upon TGFbeta stimulation accumulate in the nucleus and regulate the transcription of target genes. To investigate the mechanisms of Smad nuclear accumulation, we developed a simple mathemat...

A large body of the published literature in nuclear image analysis do not evaluate their findings on an independent data set. Hence, if several features are evaluated on a limited data set over-optimistic results are easily achieved. In order to find features that separate different outcome classes of interest, statistical evaluation of the nuclear features must be performed. Furthermore, to cl...

In 1991, we proposed a model in which nucleus is=20 treated as a spherical symmetric MIT bag and nucleon satisfies the MIT bag model boundary condition. The model was employed to calculate=20 nuclear magnetic moments. The results are in good agreement with=20 experiment data. Now, we found this model is still interesting and=20 illuminating. ∗Email:[email protected]

The experimental results on the pion, strangeness and J/ψ production in high energy nuclear collisions are discussed. The anomalous energy dependence of pion and strangeness production is consistent with the hypothesis that a transition to a deconfined phase takes place between the top AGS (≈ 15 A·GeV) and the SPS (≈ 200 A·GeV) energies. The J/ψ production systematics at the SPS can be understo...

The statistical Thomas-Fermi model is applied to a comprehensive survey of macroscopic nuclear properties. The model uses a Seyler-Blanchard effective nucleonnucleon interaction, generalized by the addition of one momentum-dependent and one density-dependent term. The adjustable parameters of the interaction were fitted to shell-corrected masses of 1654 nuclei, to the diffuseness of the nuclear...
