Free Piston Linear Generator (FPLG) is an ideal power resource in Hybrid Electric Vehicle (HEV) for its potential advantages of low friction loss, variable compression ratio, being suitable for various fuels, high thermal efficiency, etc. No FPLG has been successfully applied to an actual vehicle as lack of reliable control. The first part of this paper consists of introduction to FPLG and its research status. Structure and working principle of FPLG are analyzed in the second part. Then the thermodynamic process is analyzed and mathematical models of all kinds of FPLG using real-time motion control strategy based on location domain are established. After these, verifying work of the six different models established before and the realtime control strategy is carried out. Results show that the mathematical models of FPLG based on location domain work well and the control strategy effects with proper linear generator.

Mechanisms Underlying the Role of Myeloid-Derived Suppressor Cells in Clinical Diseases: Good or Bad
Ge Yongtong,Cheng Dalei,Jia Qingzhi,Xiong Huabao,Zhang Junfeng 대한면역학회 2021 Immune Network Vol.21 No.3
Myeloid-derived suppressor cells (MDSCs) have strong immunosuppressive activity and are morphologically similar to conventional monocytes and granulocytes. The development and classification of these cells have, however, been controversial. The activation network of MDSCs is relatively complex, and their mechanism of action is poorly understood, creating an avenue for further research. In recent years, MDSCs have been found to play an important role in immune regulation and in effectively inhibiting the activity of effector lymphocytes. Under certain conditions, particularly in the case of tissue damage or inflammation, MDSCs play a leading role in the immune response of the central nervous system. In cancer, however, this can lead to tumor immune evasion and the development of related diseases. Under cancerous conditions, tumors often alter bone marrow formation, thus affecting progenitor cell differentiation, and ultimately, MDSC accumulation. MDSCs are important contributors to tumor progression and play a key role in promoting tumor growth and metastasis, and even reduce the efficacy of immunotherapy. Currently, a number of studies have demonstrated that MDSCs play a key regulatory role in many clinical diseases. In light of these studies, this review discusses the origin of MDSCs, the mechanisms underlying their activation, their role in a variety of clinical diseases, and their function in immune response regulation.
