ALICE is one of the four major LHC experiments at CERN. When the accelerator enters the Run 3 data-taking period, starting in 2021, ALICE expects almost 100 times more Pb-Pb central collisions than now, resulting in a large increase of data throughput. In order to cope with this new challenge, the collaboration had to extensively rethink the whole data processing chain, with a tighter integration between Online and Offline computing worlds. Such a system, code-named ALICE O2, is being developed in collaboration with the FAIR experiments at GSI. It is based on the ALFA framework which provides a generalized implementation of the ALICE High Level Trigger approach, designed around distributed software entities coordinating and communicating via message passing. We will highlight our efforts to integrate ALFA within the ALICE O2 environment. We analyze the challenges arising from the different running environments for production and development, and conclude on requirements for a flexible and modular software framework. In particular we will present the ALICE O2 Data Processing Layer which deals with ALICE specific requirements in terms of Data Model. The main goal is to reduce the complexity of development of algorithms and managing a distributed system, and by that leading to a significant simplification for the large majority of the ALICE users.

In this paper, a semi-empirical molecular dynamics model is developed. The central collisions of C 60 + C 60 and X@C 60 + X@C 60 ( X = He , Ne , Ar ) at various incident energy are investigated within this model. The fullerene dimers like a "dumbbell" can be formed by a self-assembly of C 60 fullerene and X@C 60 ( X = He , Ne ) endohedral fullerenes, and the new fullerene structure like "peanut" can be formed by a self-assembly of Ar@C 60. It is found that Ar atom plays a great role in the collision of Ar@C 60 + Ar@C 60 because of its size effect. The energy effect is found that various incident energies cannot change the final structure at low energies if they are below a certain energy.
