As the high-density nuclear equation of state(EOS) is not very well constrained, we suggest that the structural properties from the finite systems can be used to extract a more accurate constraint. By including the strangeness degrees of freedom, the hyperon or anti-kaon, the finite systems can then have a rather high-density core which is relevant to the nuclear EOS at high densities directly. It is found that the density dependence of the symmetry energy is sensitive to the properties of multi-K hypernuclei, while the high-density EOS of symmetric matter correlates sensitively to the properties of kaonic nuclei.

The newly discovered neutron halos in the excited states of nuclei 12B, 13C, and 209pb are studied by therelativistic mean-field theory. The calculated binding energies are very close to the experimental ones. The experimentally extracted root-mean-square radii of the last neutron with different occupations in nuclei are well reproduced bycalculations. New candidates for the neutron halos in excited states are predicted and are useful for further search ofneutron halos in the excited states of stable nuclei.

Under thermodynamic equilibrium, the initial values of the quark-gluon system from relativistic nucleus-nucleus collisions are obtained. From these initial values we have studied the dilepton production on the basis of the relativistic hydrodynamic model, and found that with increasing incident energy a characteristic plateau indicating the formation of the quark-gluon plasma appears in the total yield.

Background Circumferential pulmonary vein isolation （CPVI）, as the basal ablation strategy for treating atrial fibrillation （AF）, not only isolates the connection between the left atrium （LA） and the pulmonary veins （PVs）, but also induces extensive atrial endocardia damage. This could have an effect on the sinus pulse conduction in the LA and subsequently result in changes of P-wave characteristics of surface electrocardiogram （ECG）. Methods Fifty consecutive patients underwent CPVI for symptomatic drug-refractory paroxysmal AF. The 12-lead ECGs were recorded one day before CPVI and seven days after CPVI at sinus rhythm by a standard resting ECG device. Measured characteristics of the P-wave consisted of P-wave duration （PWD）, P-wave amplitude （PWA）, P-wave polarity （PWP）, P-wave notch, P-wave dispersion and P-wave index. Results After CPVI, a prevalent decrease of PWD, PWA, and P-wave dispersion was observed; a transition of P-wave polarity was observed in the leads of III, aVL and aVF. The rate of P-wave notch decreased significantly in all leads, especially in the leads of II, III, aVF and V3. Patients with sinus rhythm had a shorter P-wave dispersion and P-wave index and had a lower rate of P-wave notch compared with the patients with recurrent atrial tachyarrhythmia. Conclusion Observations from using the surface ECG showed that CPVI has instant effects on the electrical conduction in the LA, and several changes of P-wave characteristics associated with development olAF are improved by CPVI.

The de-excitation energy of superdeformed secondary minima of odd-odd Au isotopes is investigated using the relativistic mean field model with the inclusion of the isoscalar-isovector coupling. It is shown that the de-excitation energies of superdeformed secondary minima relative to the ground states can serve as a significant probe to the density dependence of the symmetry energy.
