Delay Controlled Partial Synchronization in Complex Networks - Jakub Sawicki - Bog - Springer Nature Switzerland AG - Plusbog.dk

Delay Controlled Partial Synchronization in Complex Networks - Jakub Sawicki - Bog - Springer Nature Switzerland AG - Plusbog.dk

The focus of this thesis are synchronization phenomena in networks and their intrinsic control through time delay, which is ubiquitous in real-world systems ranging from physics and acoustics to neuroscience and engineering. We encounter synchronization everywhere and it can be either a helpful or a detrimental mechanism. In the first part, after a survey of complex nonlinear systems and networks, we show that a seemingly simple system of two organ pipes gives birth to complex bifurcation and synchronization scenarios. Going from a 2-oscillator system to a ring of oscillators, we encounter the intriguing phenomenon of chimera states which are partial synchrony patterns with coexisting domains of synchronized and desynchronized dynamics. For more than a decade scientist have tried to solve the puzzle of this spontaneous symmetry-breaking emerging in networks of identical elements. We provide an analysis of initial conditions and extend our model by the addition of time delay and fractal connectivities. In the second part, we investigate partial synchronization patterns in a neuronal network and explain dynamical asymmetry arising from the hemispheric structure of the human brain. A particular focus is on the novel scenario of partial relay synchronization in multiplex networks. Such networks allow for synchronization of the coherent domains of chimera states via a remote layer, whereas the incoherent domains remain desynchronized. The theoretical framework is demonstrated with different generic models.

Algebraic and Differential Methods for Nonlinear Control Theory - Rafael Martinez Guerra - Bog - Springer Nature Switzerland AG - Plusbog.dk

Algebraic and Differential Methods for Nonlinear Control Theory - Rafael Martinez Guerra - Bog - Springer Nature Switzerland AG - Plusbog.dk

This book is a short primer in engineering mathematics with a view on applications in nonlinear control theory. In particular, it introduces some elementary concepts of commutative algebra and algebraic geometry which offer a set of tools quite different from the traditional approaches to the subject matter. This text begins with the study of elementary set and map theory. Chapters 2 and 3 on group theory and rings, respectively, are included because of their important relation to linear algebra, the group of invertible linear maps (or matrices) and the ring of linear maps of a vector space. Homomorphisms and Ideals are dealt with as well at this stage. Chapter 4 is devoted to the theory of matrices and systems of linear equations. Chapter 5 gives some information on permutations, determinants and the inverse of a matrix. Chapter 6 tackles vector spaces over a field, Chapter 7 treats linear maps resp. linear transformations, and in addition the application in linear control theory of some abstract theorems such as the concept of a kernel, the image and dimension of vector spaces are illustrated. Chapter 8 considers the diagonalization of a matrix and their canonical forms. Chapter 9 provides a brief introduction to elementary methods for solving differential equations and, finally, in Chapter 10, nonlinear control theory is introduced from the point of view of differential algebra.

Vascular Differentiation and Plant Hormones - Roni Aloni - Bog - Springer Nature Switzerland AG - Plusbog.dk

Vascular Differentiation and Plant Hormones - Roni Aloni - Bog - Springer Nature Switzerland AG - Plusbog.dk

The book is intended as a guide for molecular biology students, equipping them to successfully study plants. It pursues a holistic approach, viewing the whole plant as an integrated operating organism, and is written in a straightforward manner, making it appealing to anyone interested in plants. Further, it reflects the latest findings for scientists and students in the fields of plant sciences, biology, agriculture, forestry, ecology, vascular medicine and cancer, discussing e.g. how hormonal signals induce and regulate simple and complex patterns in plants vascular tissues, their adaptation and evolution. • written by a world-renowned expert who has worked in the field for 50 years • covers the field from the initial studies conducted more than a century ago up to recent studies with up-to-date explanations • describes in details the structure, development, physiology and basic molecular biology of plants'' vascular tissues, their function, regeneration and environmental adaptation • explores the controlling mechanisms of plant vascular differentiation by continuously moving hormonal signals and their precursors • discusses the regulation of stem cells and cambium, control of gradients in vascular cell size along the plant, juvenile-adult transition and rejuvenation, grafting, mechanisms of recovery from bending by reaction wood, evolution of vessels and fibers from tracheids, regulation of ring-porous wood evolution, protecting mechanisms against insects and pathogens, parasitism, plant cancer, and more • helps readers understand the scope and breadth of plant vascular systems in 20 detailed, high-quality chapters • includes a wealth of outstanding original color photographs and illustrations documenting the formation of vascular tissues • provides an in-depth understanding of plant biology by studying their vascular tissues

The Global Rule of Three - Raj Sisodia - Bog - Springer Nature Switzerland AG - Plusbog.dk

The Global Rule of Three - Raj Sisodia - Bog - Springer Nature Switzerland AG - Plusbog.dk

In our increasingly digital, mobile, and global world, the existing theories of business and economics have lost much of their appeal with the phenomenal rise of Chindia, the reality of Brexit, the turmoil caused by the Covid-19 pandemic, and the seismic shifting of the global center of gravity from west to east. In the area of innovation, the traditional thinking that a developed country, often the US, will come up with the next major innovation, launch at home first, and then take it to other markets does not ring true anymore. Similarly, the world where conglomerates go bargain-hunting for acquisitions in emerging markets has been turned upside-down. This book reveals and illustrates the Global Rule of Three phenomenon, which stipulates that in competitive markets only three companies (which the authors call "generalists") can dominate the market. All other players in the market are specialists. Further, whereas the financial performance of generalists improves as market share increases, specialist companies see a decrease in financial performance as their market share increases, as the latter are margin-driven companies. This theory powerfully captures the evolution of global markets and what executives must do to succeed. It is based on empirical analyses of hundreds of markets and industries in the US and globally. Competitive markets evolve in a predictable fashion across industries and geographies, where every industry goes through a similar lifecycle from beginning to end (or revitalization). From local to regional to national markets, the last stop in the evolution of markets is going global. The pattern is so consistent that it represents a distinct and natural market structure at every level. The authors offer strategies that generalists and specialist should follow to stay competitive as well as twelve expansion strategies for global companies from emerging markets. This book chronicles this global evolution and provides impactful managerial implications for executives and students of marketing and corporate strategy alike.
