Book Synopsis Fluctuating Asymmetry of Plants: Methods and Application by : Baranov Sergey

Download or read book Fluctuating Asymmetry of Plants: Methods and Application written by Baranov Sergey. This book was released on 2015-07-08. Available in PDF, EPUB and Kindle. Book excerpt: The value of the fluctuating asymmetry shows the relative ineffectiveness of organismic control systems developmental processes. Assessment of the environmental quality is now a very promising approach for the integral characteristic of living organisms. Stability of development is characterized by the level of fluctuating asymmetry in morphological structures. In this monograph the morphogeometric method was applied to assess the FA leaf plate woody plants (birch, oak, linden and maple). Results of the developmental stability monitoring in plant ecosystems were reported on the example of one of the region in Russia.

Book Synopsis Developmental Instability by : Michal Polak

Download or read book Developmental Instability written by Michal Polak. This book was released on 2003. Available in PDF, EPUB and Kindle. Book excerpt: The field of developmental instability has generated a large amount of controversy recently, mostly because of fierce disagreement over the genetic basis of fluctuating asymmetry and its role in mate selection. This book is a timely and innovative critical evaluation of a burgeoning field. The book explores the premise that complex organismal, ecological and evolutionary processes can be understood as emergent properties of the "epigenetic machine," that is, the mechanisms fundamental to all organisms responsible for building and organizing phenotypes from information translated from DNA.

Book Synopsis Asymmetry in Plants by : Bir Bahadur

Download or read book Asymmetry in Plants written by Bir Bahadur. This book was released on 2019-03-25. Available in PDF, EPUB and Kindle. Book excerpt: Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach

Book Synopsis Computational Symmetry in Computer Vision and Computer Graphics by : Yanxi Liu

Download or read book Computational Symmetry in Computer Vision and Computer Graphics written by Yanxi Liu. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: In the arts and sciences, as well as in our daily lives, symmetry has made a profound and lasting impact. Likewise, a computational treatment of symmetry and group theory (the ultimate mathematical formalization of symmetry) has the potential to play an important role in computational sciences. Though the term Computational Symmetry was formally defined a decade ago by the first author, referring to algorithmic treatment of symmetries, seeking symmetry from digital data has been attempted for over four decades. Computational symmetry on real world data turns out to be challenging enough that, after decades of effort, a fully automated symmetry-savvy system remains elusive for real world applications. The recent resurging interests in computational symmetry for computer vision and computer graphics applications have shown promising results. Recognizing the fundamental relevance and potential power that computational symmetry affords, we offer this survey to the computer vision and computer graphics communities. This survey provides a succinct summary of the relevant mathematical theory, a historic perspective of some important symmetry-related ideas, a partial yet timely report on the state of the arts symmetry detection algorithms along with its first quantitative benchmark, a diverse set of real world applications, suggestions for future directions and a comprehensive reference list.
