Hypoelliptic estimates and spectral theory for Fokker-Planck operators and witten Laplacians
There has recently been a renewal of interest in Fokker-Planck operators, motivated by problems in statistical physics, in kinetic equations and differential geometry. Compared to more standard problems in the spectral theory of partial differential operators, those operators are not self-adjoint and only hypoelliptic. The aim of the analysis is to give, as generally as possible, an accurate qualitative and quantitative description of the exponential return to the thermodynamical equilibrium. While exploring and improving recent results in this direction this volume proposes a review of known techniques on: the hypoellipticity of polynomial of vector fields and its global counterpart; the global Weyl-Hörmander pseudo-differential calculus, the spectral theory of non-self-adjoint operators, the semi-classical analysis of Schrödinger-type operators.
Hyperbolic Geometry
The geometry of the hyperbolic plane has been an active and fascinating field of mathematical inquiry for most of the past two centuries. The basic approach taken is to define hyperbolic lines and develop a natural group of transformations preserving hyperbolic lines, and then study hyperbolic geometry as those quantities invariant under this group of transformations. Topics covered include the upper half-plane model of the hyperbolic plane, Möbius transformations, the general Möbius group, and their subgroups preserving the upper half-plane, hyperbolic arc-length and distance as quantities invariant under these subgroups, the Poincaré disc model, convex subsets of the hyperbolic plane, hyperbolic area, the Gauss-Bonnet formula and its applications.
Hydropower Economics
HYDROPOWER ECONOMICS examines sustainable alternate energy sources beginning with modeling hydropower and extending the model to include thermal power and wind power. The book will use various econometric measures, equilibrium metrics, OR methods, and DEA/productivity analyses to analyze and model the optimal use of these alternate energy sources. Because these problems are dynamic in nature, dynamic methods are used to model the problems. The book derives results on the allocation of the amounts of alternate sources of energy (water, thermal, and wind) required to produce electricity at acceptable levels over time. Graphic illustrations of the analytical and mathematical modeling used to reach research conclusions are used throughout the book.

Does it exist at all? Under what conditions useful recoveries can be achieved? Are there new developments in physical medicine and physiotherapy? Can the quality of recovery be influenced by surgery on muscles to provide a better equilibrium of forces? To what extent cerebral plasticity may be exploited to improve functional results? The contributions in this book give answers to all of these questions.
How generations remember : Conflicting histories and shared memories in post-war Bosnia and Herzegovina
Provides a profound insight into post-war Mostar, and the memories of three generations of this Bosnian-Herzegovinian city. Drawing on several years of ethnographic fieldwork, it offers a vivid account of how personal and collective memories are utterly intertwined, and how memories across the generations are reimagined and ‘rewritten’ following great socio-political change. Focusing on both Bosniak-dominated East Mostar and Croat-dominated West Mostar, it demonstrates that, even in this ethno-nationally divided city with its two divergent national historiographies, generation-specific experiences are crucial in how people ascribe meaning to past events.

Housing Market Dynamics in Africa
Utilizes new data to thoroughly analyze the main factors currently shaping the African housing market. Some of these factors include the supply and demand for housing finance, land tenure security issues, construction cost conundrum, infrastructure provision, and low-cost housing alternatives. Through detailed analysis, the authors investigate the political economy surrounding the continent’s housing market and the constraints that behind-the-scenes policy makers need to address in their attempts to provide affordable housing for the majority in need. With Africa’s urban population growing rapidly, this study highlights how broad demographic shifts and rapid urbanization are placing enormous pressure on the limited infrastructure in many cities and stretching the economic and social fabric of municipalities to their breaking point. But beyond providing a snapshot of the present conditions of the African housing market, the book offers recommendations and actionable measures for policy makers and other stakeholders on how best to provide affordable housing and alleviate Africa’s housing deficit.
Housing Estates in Europe : Poverty, Ethnic Segregation and Policy Challenges
Explores the formation and socio-spatial trajectories of large housing estates in Europe. Are these estates clustered or scattered? Which social groups originally had access to residential space in housing estates? What is the size, scale and geography of housing estates, their architectural and built environment composition, services and neighbourhood amenities, and metropolitan connectivity? How do housing estates contribute to the urban mosaic of neighborhoods by ethnic and socio-economic status? What types of policies and planning initiatives have been implemented in order to prevent the social downgrading of housing estates?The collection of chapters in this book addresses these questions from a new perspective previously unexplored in scholarly literature. The social aspects of housing estates are thoroughly investigated (including socio-demographic and economic characteristics of current and past inhabitants; ethnicity and segregation patterns; population dynamics; etc.), and the physical composition of housing estates is described in significant detail (including building materials; building form; architectural and landscape design; built environment characteristics; etc.).

Hot Property : The Housing Market in Major Cities
This book discusses booming housing markets in cities around the globe, and the resulting challenges for policymakers and central banks. Cities are booming everywhere, leading to a growing demand for urban housing. In many cities this demand is out-pacing supply, which causes house prices to soar and increases the pressure on rental markets. These developments are posing major challenges for policymakers, central banks and other authorities responsible for ensuring financial stability, and economic well-being in general. This volume collects views from high-level policymakers and researchers, providing essential insights into these challenges, their impact on society, the economy and financial stability, and possible policy responses. The respective chapters address issues such as the popularity of cities, the question of a credit-fueled housing bubble, the role of housing supply frictions and potential policy solutions. Given its scope, the book offers a revealing read and valuable guide for everyone involved in practical policymaking for housing markets, mortgage credit and financial stability.

Beginning with animal-pathogen interactions, the book then continues with chapters exploring virus-host interactions, plant-microbe interactions, as well as different molecular techniques that were initially applied to non-pathogenic interactions but can be adapted to study other host-pathogen associations. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips for troubleshooting and avoiding known pitfalls.
Hormones, metabolism and the benefits of exercise
The world is faced with an epidemic of metabolic diseases such as obesity and type 2 diabetes. This is due to changes in dietary habits and the decrease in physical activity. Exercise is usually part of the prescription, the first line of defense, to prevent or treat metabolic disorders. However, we are still learning how and why exercise provides metabolic benefits in human health. This open access volume focuses on the cellular and molecular pathways that link exercise, muscle biology, hormones and metabolism. This will include novel “myokines” that might act as new therapeutic agents in the future.
Hormones and the brain
Peripheral hormones have a major impact on the brain: they are able to interfere with its development, to affect release of neurotransmitters and concentrations of receptors, to trigger growth factors involved in lesion repair. These multiple actions account for their capacity to modulate a number of physiological parameters, from reproductive functions to memory, behaviour and aging. Depending upon intensity and duration of exposure, they can be either neuroprotective or neurotoxic, for instance by affecting production of free radicals. This book, based on contributions of pioneer investigators in the field, outlines the ambiguous actions of gonadal steroids (estradiol, progesterone, testosterone, inhibin and activin) and of neurosteroids, related moieties produced in the brain itself. After summarizing their multiple mechanisms of action, which involve both direct effects on neuronal membranes and activation of genes coding for specific proteins in neurons or glial cells, the book outlines the role of hormones in pathogenic processes such as mental disturbances or neurodegenerative diseases.
Homogenization of Partial Differential Equations
Homogenization is a method for modeling processes in microinhomogeneous media, which are encountered in radiophysics, filtration theory, rheology, elasticity theory, and other domains of mechanics, physics, and technology. These processes are described by PDEs with rapidly oscillating coefficients or boundary value problems in domains with complex microstructure. From the technical point of view, given the complexity of these processes, the best techniques to solve a wide variety of problems involve constructing appropriate macroscopic (homogenized) models. The present monograph is a comprehensive study of homogenized problems, based on the asymptotic analysis of boundary value problems as the characteristic scales of the microstructure decrease to zero. The work focuses on the construction of nonstandard models: non-local models, multicomponent models, and models with memory.
