This self-contained treatment of field quantization requires no prior knowledge of nonlinear optics. Supplemented by end-of-chapter exercises and detailed examples of calculation techniques in different systems, it is a valuable resource for graduate students and researchers in nonlinear optics, condensed matter physics, quantum information and atomic physics.
This book provides an introduction to decision analytic cost-effectiveness modelling, giving the theoretical and practical knowledge required to design and implement analyses that meet the methodological standards of health technology assessment organisations. The book guides you through building a decision tree and Markov model and, importantly, shows how the results of cost-effectiveness analyses are interpreted. Given the complex nature of cost-effectiveness modelling and the often unfamiliar language that runs alongside it, we wanted to make this book as accessible as possible whilst still providing a comprehensive, in-depth, practical guide that reflects the state of the art – that includes the most recent developments in cost-effectiveness modelling. Although the nature of cost effectiveness modelling means that some parts are inevitably quite technical, across the 13 chapters we have broken down explanations of theory and methods into bite-sized pieces that you can work through at your own pace; we have provided explanations of terms and methods as we use them. Importantly, the exercises and online workbooks allow you to test your skills and understanding as you go along.
Although sensory and autonomic nerve fibres generally do not interact directly, both may exert influences on blood flow during inflammation. For example, the sympathetic neurotransmitter noradrenaline/norepinephrine evokes axon reflexes, a response that involves release of vasoactive neuropeptides from the peripheral terminals of primary nociceptive afferent fibres. As well as boosting inflammation, this mechanism could play a role in normal renal function and heat dispersal from the skin. In certain disease states, aberrant communication between sensory and autonomic nerves might not only aggravate symptoms but also contribute to clinical deterioration by altering local circulatory dynamics. For example, in certain forms of neuropathic pain, an aberrant expression of α1-adrenoceptors on primary nociceptive afferents may provide a framework for cross-talk between sensory and autonomic nerve fibres. In addition to evoking pain and other unpleasant symptoms, this cross-talk could aggravate inflammation and disrupt nutritive perfusion of affected tissues. Finally, in disorders such as cluster headache, intense bursts of trigeminal nociceptive activity may trigger trigeminal-parasympathetic vasodilator reflexes which, in turn, provoke secondary vascular disturbances that amplify pain. A clearer understanding of sensory-autonomic interactions both in health and disease may provide a basis for new treatment approaches for conditions that respond poorly to conventional treatments.
