Book Description
This thesis establishes a multifaceted extension of the deterministic control framework that has been a workhorse of nonequilibrium statistical mechanics, to stochastic, discrete, and autonomous control mechanisms. This facilitates the application of ideas from stochastic thermodynamics to the understanding of molecular machines in nanotechnology and in living things. It also gives a scale on which to evaluate the nonequilibrium energetic efficiency of molecular machines, guidelines for designing effective synthetic machines, and a perspective on the engineering principles that govern efficient microscopic energy transduction far from equilibrium. The thesis also documents the author’s design, analysis, and interpretation of the first experimental demonstration of the utility of this generally applicable method for designing energetically-efficient control in biomolecules. Protocols designed using this framework systematically reduced dissipation, when compared to naive protocols, in DNA hairpins across a wide range of experimental unfolding speeds and between sequences with wildly different physical characteristics.

Book Description
After an insightful introductory part on recent developments in the thermodynamics of small systems, the author presents his contribution to a long-standing problem, namely the connection between irreversibility and dissipation. He develops a method based on recent results on fluctuation theorems that is able to estimate dissipation using only information acquired in a single, sufficiently long, trajectory of a stationary nonequilibrium process. This part ends with a remarkable application of the method to the analysis of biological data, in this case, the fluctuations of a hair bundle. The third part studies the energetics of systems that undergo symmetry breaking transitions. These theoretical ideas lead to, among other things, an experimental realization of a Szilard engine using manipulated colloids. This work has the potential for important applications ranging from the analysis of biological media to the design of novel artificial nano-machines.

Book Description
Non-Reciprocal Materials and Systems: An Engineering Approach to the Control of Light, Sound, and Heat discusses the related concept of bound states which help confine sound and electromagnetic waves and can also lead to the control of thermal energy. The requirements for the formation of such bound states, their relationship to physical and topological characteristics of materials, and the possible application to new devices is considered. The book takes a unique approach to energy transfer in and between materials systems - considering dimensional effects, supersonic, transonic and subsonic wave motion, as well as the coupling of waves. This book is suitable for researchers in materials science, condensed matter physics, electrical, mechanical, and structural engineering, and technologists aiming for better control of non-electronic physical phenomena. - Provides information on how to use specific features in new and artificial materials for the control of sound, light and heat - Explores dimensional considerations such as surface material phenomena that can be decoupled from bulk materials or the inside of a material - Discusses new device concepts and related technologies such as energy sources, isolators, and diodes involving energy confinement

Book Description
This book aims to provide an example-based education in numerical methods for atomistic and continuum simulations of systems at and away from equilibrium. The focus is on nonequilibrium systems, stressing the use of tools from dynamical systems theory for their analysis. Lyapunov instability and fractal dimensionality are introduced and algorithms for their analysis are detailed. The book is intended to be self-contained and accessible to students who are comfortable with calculus and differential equations.The wide range of topics covered will provide students, researchers and academics with effective tools for formulating and solving interesting problems, both atomistic and continuum. The detailed description of the use of thermostats to control nonequilibrium systems will help readers in writing their own programs rather than being saddled with packaged software.

Book Description
This book aims to provide a lively working knowledge of the thermodynamic control of microscopic simulations, while summarizing the historical development of the subject, along with some personal reminiscences. Many computational examples are described so that they are well-suited to learning by doing. The contents enhance the current understanding of the reversibility paradox and are accessible to advanced undergraduates and researchers in physics, computation, and irreversible thermodynamics.

Book Description
Statistical mechanics provides a framework for relating the properties of macroscopic systems (large collections of atoms, such as in a solid) to the microscopic properties of its parts. However, what happens when macroscopic systems are not in thermal equilibrium, where time is not only a relevant variable, but also essential? That is the province of nonequilibrium statistical mechanics – there are many ways for systems to be out of equilibrium! The subject is governed by fewer general principles than equilibrium statistical mechanics and consists of a number of different approaches for describing nonequilibrium systems. Financial markets are analyzed using methods of nonequilibrium statistical physics, such as the Fokker-Planck equation. Any system of sufficient complexity can be analyzed using the methods of nonequilibrium statistical mechanics. The Boltzmann equation is used frequently in the analysis of systems out of thermal equilibrium, from electron transport in semiconductors to modeling the early Universe following the Big Bang. This book provides an accessible yet very thorough introduction to nonequilibrium statistical mechanics, building on the author's years of teaching experience. Covering a broad range of advanced, extension topics, it can be used to support advanced courses on statistical mechanics, or as a supplementary text for core courses in this field. Key Features: Features a clear, accessible writing style which enables the author to take a sophisticated approach to the subject, but in a way that is suitable for advanced undergraduate students and above Presents foundations of probability theory and stochastic processes and treats principles and basic methods of kinetic theory and time correlation functions Accompanied by separate volumes on thermodynamics and equilibrium statistical mechanics, which can be used in conjunction with this book

Book Description
Embracing the theory and practice of strategic foresight and illuminating how different schools of thought regard its role in policy making, Tuomo Kuosa describes how something not traditionally considered an independent discipline, is steadily becoming one. In The Evolution of Strategic Foresight he explains how the practice of strategic foresight has long been closely associated with the military and politics. Linking strategic thinking more broadly to futurology, however, it is quite new. Since strategic foresight refers to the practice of generating analyses of alternative futures and strategies, based on available intelligence and foreknowledge, the practice can and should be applied to companies, business sectors, national and trans-national agencies of all descriptions, and to all aspects of public policy making. The author explains its practice in terms of structure, process, and knowledge domains, and examines its methodologies and systems, along with how strategic foresight can be used to produce better knowledge and be more effectively linked to policy making. Using examples from 30 different countries and with access to interviews and workshops involving key experts, The Evolution of Strategic Foresight will be valuable to scholars, educators, students engaged in strategy and future studies, long-range, public policy and urban planners, analysts; risk assessment experts, and consultants, managers and decision makers in many organisations, public and private.

Book Description
This collection of lectures treats the dynamics of open systems with a strong emphasis on dissipation phenomena related to dynamical chaos. This research area is very broad, covering topics such as nonequilibrium statistical mechanics, environment-system coupling (decoherence) and applications of Markov semi-groups to name but a few. The book addresses not only experienced researchers in the field but also nonspecialists from related areas of research, postgraduate students wishing to enter the field and lecturers searching for advanced textbook material.
