Focusing on the health challenges faced by rural-urban migrants in China, the book examines social strata and networks that influence health service access. It highlights the lack of equal social protection and identifies institutional barriers, such as the household registration system, as key obstacles. Additionally, it emphasizes the crucial role of social networks in facilitating health access and critiques the migrants' limited understanding of health, attributing this to their rural backgrounds rather than personal shortcomings.

Focusing on the microstructure and properties of plant fibers, this book explores their role in creating eco-friendly, fiber-reinforced composites. It details the manufacturing processes, mechanical behaviors, and engineering applications of these materials, emphasizing their renewability and biodegradability. By integrating theory with practical applications, it serves as a valuable resource for students and professionals in fields like aerospace and automotive engineering, aiming to advance the design of sustainable composites.

Focusing on cyber-physical microgrid networks, this textbook offers a comprehensive introduction to renewable energy technologies, including photovoltaics, batteries, and wind generation. It equips upper-level undergraduate and graduate students with essential knowledge on microgrid modeling, stability analysis, and cyber-communication security. By integrating theoretical research with practical applications, the text serves as a vital resource for understanding the operational mechanisms of microgrids, complemented by examples and test systems for enhanced problem-solving skills.

Die Ausbeute von DRAM Schaltungen gestaltet sich zunehmend schwieriger mit zunehmender Speicher dichte und immer kleiner werdenden Strukturgrößen. Basierend auf statistischen Methoden und einem analytischen, hierarchisch aufgebauten Schaltungsmodell wird in dieser Dissertation die elektrische Ausbeute von beliebigen DRAM Schaltungen analyisiert. Mit Hilfe dieses Modells kann die Ausbeute von DRAM Schaltungen bezüglich Fläche, Versorgungsspannung, Zellenfeldarchitektur und Ungenauigkeiten der Verstärkerparameter optimiert werden. Mit den hier entwickelten Methoden können DRAM - Schaltungen robuster und flächeneffizienter realisiert werden. Diese Arbeit bietet damit einen Leitfaden für Ausbeute - optimiertes Design in zukünftigen DRAM Schaltungen mit hohen Speicherdichten.
