摘要：
Heavy flavor physics in high-energy heavy-ion collisions is a promising and active area to study the mass dependence of the "jet quenching " effects both at the RHIC and the LHC. In this talk, we present the first theoretical study on the D-0 meson radial distributions relative to the jet axis both in p+p and Pb+Pb collisions at root s(NN) = 5.02 TeV, where a nice agreement of our results with experimental data is observed. The in-medium parton propagations are described by a Monte Carlo transport model which uses the next-to-leading order (NLO) plus parton shower (PS) event generator SHERPA as input and includes elastic (collisional) and inelastic (radiative) in-medium interaction of heavy flavor jet. We find that, at low D-0 meson p(T), the radial distribution significantly shifts to larger radius indicating a strong diffusion effect, and the diffusion effects decrease quickly with p(T) ,which is consistent with the recent CMS measurements. We demonstrate that the angular deviation of charm quarks is sensitive to D-s but not (q) over cap, which may provide new constrains on the collisional and radiative heavy quark energy loss.
摘要：
Measurements of the semi-inclusive distribution of charged jets recoiling from a trigger hadron in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV are presented. This technique provides precise, data-driven subtraction of the large uncorrelated background in jet measurements. It uniquely enables the exploration of medium-induced modification of jet production and acoplanarity over wide phase space, including low transverse momentum (p(T)) and large resolution parameter (R) jets. This proceeding reports the measurements of medium-induced jet energy redistribution through the comparison of trigger-normalized recoil jet yields in pp and Pb-Pb collisions, and for jets with different R.

摘要：
We report recent results of strangeness production in Au+Au collisions at root s(NN) = 54.4 GeV and Al+Au fixed-target collisions at root s(NN) = 4.9 GeV from the STAR experiment at RHIC. The collision-energy dependence of strange hadron yields is presented. The p(T) dependance of nuclear modification factor (R-CP) and baryon to meson ratio ((Lambda) over bar /K-S(0) are measured to study the recombination and parton energy loss mechanisms. The STAR fixed-target data are compared to the previous published data from different AGS experiments. The physics implications for collision dynamics are discussed.

摘要：
Modern software systems, such as Spark, are usually written in multiple programming languages (PLs). Besides benefiting from code reuse, such systems can also take advantages of specific PLs to implement certain features, to meet various quality needs, and to improve development efficiency. In this context, a change to such systems may need to modify source files written in different PLs. We define a multi-programming-language commit (MPLC) in a version control system (e.g., Git) as a commit that involves modified source files written in two or more PLs. To our knowledge, the phenomenon of MPLCs in software development has not been explored yet. In light of the potential impact of MPLCs on development difficulty and software quality, we performed an empirical study to understand the state of MPLCs, their change complexity, as well as their impact on open time of issues and bug proneness of source files in real-life software projects. By exploring the MPLCs in 20 non-trivial Apache projects with 205,994 commits, we obtained the following findings: (1) 9% of the commits from all the projects are MPLCs, and the proportion of MPLCs in 80% of the projects goes to a relatively stable level; (2) more than 90% of the MPLCs from all the projects involve source files written in two PLs; (3) the change complexity of MPLCs is significantly higher than that of non-MPLCs in all projects; (4) issues fixed in MPLCs take significantly longer to be resolved than issues fixed in non-MPLCs in 80% of the projects; and (5) source files that have been modified in MPLCs tend to be more bug-prone than source files that have never been modified in MPLCs. These findings provide practitioners with useful insights on the architecture design and quality management of software systems written in multiple PLs.
