Oogenesis - the process by which female germ cells develop into mature eggs, or ova - is a complex process involving many important elements of developmental and cellular biology: from cell-cell interactions, complex signalling cascades, specialized cell cycles and cytoskeleton organization. Oocytes from various species (including clam, starfish, xenopus and mouse) are excellent model systems to study the biochemistry of cell division with important implications for basic and clinical research. This book describes the entire process of oogenesis in chronological order with contributions from leading international researchers and chapters covering medical and ethical considerations in oogenic...
Why can we never seem to keep on top of our workload, social diary or chores? Why does poverty persist around the world? Why do successful people do things at the last minute in a sudden rush of energy? Here, economist Sendhil Mullainathan and psychologist Eldar Shafir reveal that the hidden side behind all these problems is that they're all about scarcity.
The first book of its kind dedicated to the challenge of person re-identification, this text provides an in-depth, multidisciplinary discussion of recent developments and state-of-the-art methods. Features: introduces examples of robust feature representations, reviews salient feature weighting and selection mechanisms and examines the benefits of semantic attributes; describes how to segregate meaningful body parts from background clutter; examines the use of 3D depth images and contextual constraints derived from the visual appearance of a group; reviews approaches to feature transfer function and distance metric learning and discusses potential solutions to issues of data scalability and identity inference; investigates the limitations of existing benchmark datasets, presents strategies for camera topology inference and describes techniques for improving post-rank search efficiency; explores the design rationale and implementation considerations of building a practical re-identification system.

This book is dedicated to understanding how miRNAs affect translation. It includes chapters representing work in plants and Caenorhabditis elegans, the biological systems that originally led to the discovery of small interfering RNAs.
When one begins to examine the existing literature dealing with siblings, one soon becomes aware that many separate domains of sibling research exist and that there is little connection between them; for example, sibling relationships in early childhood, genetic and environmental influences on individual differences between siblings, dysfunctional sibling relation ships, adult sibling helping relationships, sibling violence and abuse, and so on. The author's aim in writing this book was to attempt to bring together for the first time studies from diverse areas of sibling research into a single volume. The book is a summary and integration of the various domains of sibling studies, extending across the life span where studies exist to make this possible. Although many gaps in the sibling research literature within and between domains of study and over the life span still exist, it is hoped that this book will motivate others to help fill in the gaps by suggesting direc tions where further research is needed.
This book is the first of a new series which will present the proceedings of the newly established Nestlé Nutrition Workshop Series: Clinical & Performance Programme aimed at adult nutrition. Undernutrition is a common phenomenon in elderly people, and malnutrition reaches significant levels in those being in hospital, nursing homes or home care programs. Consequences of malnutrition often go unrecognised owing to the lack of specific validated instruments to assess nutritional status in frail elderly persons. The Mini Nutritional Assessment (MNA) provides a single, rapid assessment of nutritional status in the elderly of different degrees of independence, allowing the prevalence of protein...
