The most profound dilemma in assisted reproduction to date is the inability to recognize potentially viable embryos before their replacement into the reproductive tract. Application of increasingly advanced new technology has allowed the field of embryo evaluation to evolve rapidly and dramatically over the past five years.
Human Preimplantation Embryo Selection assembles the leaders in the field of assisted reproduction to discuss their visions of dealing with the topic of embryo selection in the light of the limitations involving the fragility of the early human embryo.
The purpose of this book is to shed light on the ever-expanding techniques that are being employed and evaluated with regard to embryo selection. A comprehensive overview may guide the ART practitioner in choice of techniques and evaluation of benefits and drawbacks.
This book will provide an up-to-date overview and reference source: an invaluable tool for assisted reproductive practice worldwide.

Selecting the best embryo to transfer to the uterus is key to successful in vitro fertilization (IVF). A huge amount of research has been devoted to this topic and there are numerous methods used, from simple morphological assessment to molecular biological techniques to assess the genome and metabolism of the newly fertilized embryo. For many of these techniques, an adequate evidence base is lacking, and expert opinion is valuable. Clinical imperatives require ranking all embryos in a cohort according to their viability, thereby enabling the selection of the best embryo to optimize live birth outcome: a key indicator used to measure and rate IVF Clinics worldwide. This clear and informative manual will provide embryologists and clinicians with an overview of the tools now available to assist in embryo selection, as well as evidence for their efficacy and safety and the broader considerations that must underlie these important clinical decisions.

This is the first book entirely dedicated to the problem of memory management in programming language implementation. Its originality stems from the diversity of languages and approaches presented: functional programming, logic programming, object oriented programming, and parallel and sequential programming. The book contains 29 selected and refereed papers including 3 survey papers, 4 on distributed systems, 4 on parallelism, 4 on functional languages, 3 on logic programming languages, 3 on object oriented languages, 3 on incremental garbage collection, 2 on improving locality, 2 on massively parallel architectures, and an invited paper on the thermodynamics of garbage collection. The book provides a snapshot of the latest research in the domain of memory management for high-level programming language implementations.
