2. 1. Covalent Graphene Functionalization for the Modification of Its Physical Properties

   Author : Hu Li; Klaus Leifer; Annick Loiseau; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; functionalization; nanomechanical property; graphene nanoscroll;

   Abstract : Graphene, a two dimensional monolayer carbon sheet with the atoms tightly packed in a hexagonal lattice, has exhibited so many excellent properties, which enable graphene to break several material records with regard to carrier mobility, strength yield and thermal conductivity to name a few. Therefore, graphene has been placed as a potential candidate to allow truly next-generation material. READ MORE

4. 2. Nasopharyngeal carcinoma and Epstein-Barr virus

   Author : Li-Fu Hu; Karolinska Institutet; Karolinska Institutet; []
   Keywords : NPC; EBV; EBNAs; LMPI; LMP2; Tumorigenicity; Immunogenicity;

   Abstract : Nasopharyngeal carcinoma (NPC) is the most common tumor in southern China and also quite frequent among the Eskimos and in Alaska. NPC is invariably associated with Epstein-Barr virus (EBV). READ MORE

6. 4. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

   Author : Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Mathematics; Matematik;

   Abstract : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. READ MORE
