  • This book focuses on the basic control and filtering synthesis problems for discrete-time switched linear systems under time-dependent switching signals. Chapter 1, as an introduction of the book, gives the backgrounds and motivations of switched systems, the definitions of the typical time-dependent switching signals, the differences and links to other types of systems with hybrid characteristics and a literature review mainly on the control and filtering for the underlying systems. By summarizing the multiple Lyapunov-like functions (MLFs) approach in which different requirements on comparisons of Lyapunov function values at switching instants, a series of  methodologies are developed for the issues on stability and stabilization, and l2-gain performance or tube-based robustness for l8 disturbance, respectively, in Chapters 2 and 3. Chapters 4 and 5 are devoted to the control and filtering problems for the time-dependent switched linear systems with either polytopic uncertainties or measurable time-varying parameters in different sense of disturbances. The asynchronous switching problem, where there is time lag between the switching of the currently activated system mode and the controller/filter to be designed, is investigated in Chapter 6. The systems with various time delays under typical time-dependent switching signals are addressed in Chapter 7.

  • Modern organic synthesis has paid much attention to the chemistry of small carbocycles. Vinylidenecyclopropanes (VDCPs), which have strained cyclopropyl group connected with an allene moiety and yet are thermally stable and reactive substances in organic chemistry, are versatile intermediates in organic synthesis. In this volume, Dr. Lixiong Shao, Dr. Jianmei Lu and Prof. Dr. Min Shi review their investigations on the chemistry of VDCPs, mainly including the preparation, the reactivities upon treatment with Lewis or Brønsted acid, as well as transition metal catalysts and some other miscellaneous analogues. The contributions aroused a renaissance of cationic intermediates in the chemistry of VDCPs.

  • This book provides state-of-the-art information on advances in the diagnosis and treatment of pulmonary aspergillosis to help specialists and clinical practitioners make appropriate decisions concerning the management of patients with this condition.

    The incidence of pulmonary aspergillosis has increased steadily due to the widespread use of broad-spectrum antibiotics, cytotoxic drugs, immunosuppressive agents and adrenal hormones, as well as the growing number of organ transplantations and AIDS patients. The book discusses various aspects of the disease, including its history, characteristics, laboratory examination, imaging features, clinical diagnosis, differential diagnosis and treatment principles, and also presents illustrated case studies.

    Focusing on different characteristics in imaging and pathology, and addressing diagnostic difficulties in-depth, this clinical reference work brings together recent clinical investigations to making it a valuable resource for practitioners in the fields of respiratory and infectious diseases, oncology, intensive care, diagnostic imaging, pathology and microbiology.
