摘要：
In this proceeding, we present the new precise directed flow, v(1), measurement of pi, K, p and phi in Au+Au collisions at root s(NN) = 27, 54.4 GeV and deuteron at root s(NN) = 7.7, 11.5, 14.5 and 19.6 GeV. The first measurement of pseudorapidity and centrality dependence of the v(1) of high-p(T) (>5 GeV/c) charged hadrons in Au+Au collisions at root s(NN) = 200 GeV are reported. The elliptic flow, v(2), of identified hadrons (pi, K, p, phi, K-S(0), Lambda, Xi, Omega) in Au+Au collisions at root s(NN) = 54.4 GeV are also presented. The results are compared with model calculations to discuss the physics implications.

摘要：
We investigate the rotation effects on the mesonic condensation in isospin matter . Using the two-flavor NJL effective model with a global rotation, we demonstrate two important effects of the rotation on its phase structure: a rotational suppression of the scalar-channel condensates, in particular the pion condensation region; and a rotational enhancement of the rho condensation region with vector-channel condensate. A new phase diagram for isospin matter under rotation is mapped out on the omega - mu(I) plane where three distinctive phases, corresponding to sigma, pi, rho dominated regions respectively, are separated by a second-order line at low isospin chemical potential and a first-order line at high rotation which are further connected at a tri-critical point.
摘要：
Cognition and emotion in online collaboration play an important role in achieving high-quality collaboration performance. Especially in the online synchronous collaborative environment, the limited time and place require higher language instantaneity and flexibility of thinking, which brings great challenges to students' high cognitive behavior and emotional experience. However, few empirical studies have focused on the cognition and emotion of students in online synchronous collaboration. Therefore, a quasi-experimental study was conducted based on a creative synchronous collaboration task to explore the effects, social knowledge construction and emotional experience of Multi-Input and One-Output(MIOO) collaboration and Multi-Input and Multi-Output(MIMO) collaboration. The findings indicated that the MIMO collaboration groups performed better than the MIOO collaboration groups in creative achievements, but were more affected by technology. Besides, the MIOO collaboration groups had a higher degree of social knowledge construction and more positive emotional experiences.

摘要：
Arguments for thermalization of the QCD matter created in high-energy nuclear collisions has dominantly come from the agreement of the measured yields of produced hadrons with those from statistical thermal models. Ideally for a thermalized system, in addition to mean, the higher orders of the moments of the multiplicity distribution of produced particles should also show agreement with thermal models. In this respect, simultaneously studying the moments of the event-by-event distributions of conserved quantities like net-baryon, net-strangeness and net-charge number is best suited. We present a systematic study of comparing the results from a thermal hadron resonance gas (HRG) model with data on higher moments of net-proton, net-kaon and net-charge distributions measured at RHIC beam energy scan program. The experimental acceptances in terms of rapidity and transverse momentum are used in the model calculations which also include resonance decay. For the first time, the HRG model results are found to explain the measurements up to third order of moment with a common temperature and baryonic chemical potential. These calculations have tested the thermal nature of produced net-particle distributions up to third order, thereby providing evidence for thermalization of the QCD matter formed in such high energy heavy-ion collisions.
