This book summarizes the research results of carbide control in special steel from the authors. It includes the evolution and control of carbide in special steel in the process of electroslag remelting, rolling, and heat treatment, as well as the effect of alloying treatment (rare earth, magnesium, nitrogen, titanium) as heterogeneous nucleating agent on the carbides in special steel. It helps the readers to understand the formation mechanism and control technology of carbide in special steel deeply for improving the quality of special steel further. The book is useful as a reference for researchers, practitioners, teachers, and engineering management team in the fields of metallurgy and materials.

The ovary plays a very significant role in aging. The regenerative capacity of stem cells is the key factor to promote healthy aging, and the stem cell viability would decline sharply after the reproductive period, especially in women. Except for stem cell aging and neuroendocrine aging, ovarian aging is also a hotspot in the field of aging research. Recent researches have investigated many factors affecting ovarian function or aging, in terms of gene mutation, epigenetic erosion, endocrine dysfunction and environment-dependent extrinsic factors. This Research Topic aims to explore in detail all the factors related to ovarian aging and female reproduction outcomes. We'll discuss various age-related molecules, such as P16, P21, etc., as well as mutations in premature aging genes, such as FSHR mutations, abnormalities in the mitochondrial respiratory chain, and redox imbalances that contribute to ovarian aging. Also, we are committed to addressing the relationship between female factors and reproductive outcomes. Besides, the discussion also focus on measures to delay ovarian aging, such as antioxidant drugs, mesenchymal stem cell therapy, ovarian tissue engineering exploration, etc. 1) This Research Topic aims to provide nursing suggestions related to ovarian aging and measures to prevent ovarian aging, including psychological intervention, improving living habits, optimizing the environment and other suggestions that may delay ovarian aging, and in turn to provide tips for clinical treatment. 2) This Research Topic aims to reveal the novel factors involved in ovarian aging and their related mechanisms, including function-related gene mutations, mitochondrial and oxidative stresses’ damage, metabolism-related molecules, and the specific mechanisms of these factors. 3) This Research Topic aims to discuss the influence of female-related factors on assisted reproductive outcome, such as female age, BMI, serum hormone level, endometrial preparation program, follicular fluid quality and other factors. 4) This Research Topic aims to explore the role of stem cells and tissue engineering in delaying ovarian aging, such as mesenchymal stem cell intravenous injection and the in situ ovarian tissue transplantation. 5) This Research Topic still involves in the research on anti-aging drugs for ovaries.

State of the art resource covering key technologies and related theories of inter-satellite links Inter-Satellite Links Technology explores satellite networking as a growing topic in the field of communication technology, introducing the definition, types, and working frequency bands of inter-satellite links, discussing the number of orbital elements of the spacecraft motion state under two-body motion and their conversion relationship, and establishing the basic demand model for inter-satellite link network, chain topology model, and transmission protocol model. The book focuses on the analysis and introduction of the principles and error sources of microwave and laser inter-satellite ranging, including the basic composition, workflow, and constraints of the laser inter-satellite link, and related design principles of the inter-satellite laser transmitter and receivers. Later chapters also discuss theories and methods of acquisition, alignment, and tracking, the impact of alignment errors on performance, and inter-satellite link modulation and its implementation. Specific sample topics covered in Inter-Satellite Links Technology include: Pulse position modulation (PPM), Differential Pulse Position Modulation (DPPM), Digital Pulse Interval Modulation (DPIM), and Double-head pulse interval modulation (DH-PIM) Basic demand model of inter-satellite link network application, including basic configuration of constellations and inter-satellite transmission networks Inter-satellite ranging accuracy, principles of microwave inter-satellite ranging, and analysis of microwave ranging error sources Effect of tracking error on the beam distribution at the receiving end and influence of tracking and pointing error on communication error rate Inter-Satellite Links Technology serves a completely comprehensive resource on the subject and is a must-have reference for experts and scholars in aerospace, along with graduates and senior undergraduates in related programs of study.

How can cognition, a concept traditionally associated with the human brain, be applied to satellite systems? For the first time, cognitive system meanings and models are applied to the uncertain environmental processes of satellite systems. The authors of this book go beyond defining 'cognitive satellite systems' to design a cognitive satellite communication system architecture with satellite-to-ground coordination, which has uses in emergency response spacecraft and prediction technology.In this book, the optimal utilization of cognitive satellite system resources is discussed in four aspects:
