The central theme of this book is the study of self-dual
connections on four-manifolds. The author's aim is to present a
lucid introduction to moduli space techniques (for vector bundles
with SO (3) as structure group) and to apply them to
four-manifolds. The authors have adopted a topologists'
perspective. For example, they have included some explicit
calculations using the Atiyah-Singer index theorem as well as
methods from equivariant topology in the study of the topology of
the moduli space. Results covered include Donaldson's Theorem that
the only positive definite form which occurs as an intersection
form of a smooth four-manifold is the standard positive definite
form, as well as those of Fintushel and Stern which show that the
integral homology cobordism group of integral homology
three-spheres has elements of infinite order. Little previous
knowledge of differential geometry is assumed and so postgraduate
students and research workers will find this both an accessible and
complete introduction to currently one of the most active areas of
mathematical research.
Recent advances in genetic engineering and in the chemistry and
biochemistry of fruit and vegetables have radically changed our
understanding of the mechanisms underlying these processes, and the
potential for modification of the products themselves. This is the
first book to examine these topics and address the role of fresh
fruits and vegetables in a healthy diet and the prevention of
cancer and coronary diseases. The main focus is on the secondary
metabolites which are responsible for quality characteristics
including color, aroma, and flavor, and their nutritional
importance and role in the prevention of cancer and cardiovascular
diseases. The book also explores how the post-harvest technological
treatments to which these commodities are submitted can cause
changes in secondary metabolism, with consequences for the quality
of the product.
A major strength of American Chemical Society (ACS) is the large
number of volunteers who help to grow and sustain the organization,
from local sections to technical divisions, from regional to
national meetings, from task forces to national committees, and
from conducting research to writing and reviewing manuscripts for
journals. Some of them spend literally thousands of hours on behalf
of ACS and the global chemistry enterprise, helping students or
fellow scientists, organizing meetings and symposia, and reaching
out to the local communities. One of the people who excelled in
these efforts was the late Prof. Ernest L. Eliel. For many years he
taught at the University of Notre Dame and the University of North
Carolina and was an acknowledged leader in organic stereochemistry
and conformational analysis. He was also a leader at ACS, serving
as ACS President in 1992 and Chair of ACS Board of Directors in
1987-89. Unfortunately Prof. Eliel died in 2008, but the ACS held a
symposium in 2016 honoring his work. This book features two volumes
highlighting stereochemistry and global connectivity, which
represent two of the key legacies of Prof. Eliel. Because
stereochemistry is a fundamental chemistry concept, ongoing
research is carried out in different subfields of chemistry (such
as organic, medicinal, carbohydrates, polymers), using various
analytical techniques (such as NMR, X-ray crystallography, and
circular dichroism). The two volumes of this book contain many
research papers that represent cutting-edge research in all the
above areas. Because chemistry is now a world-wide enterprise,
global connectivity is important to chemistry practitioners, and
the chapters on international activities should be of great
interest as well.
During the past two decades international collaborative studies
have yielded extensive information on genome sequences, genome
architecture and their variations. The challenge we now face is to
understand how these variations impact structure and function of
organelles, physiological systems and phenotype. The goal of this
book is to present steps in the pathways of exploration to connect
genotype to phenotype and to consider how alterations in genomes
impact disease.
In this book the author reviews published research in functional
genomics carried out primarily since 2006 that sheds light on
aspects of phenotypic variation. The goal of functional genomics is
to gain insight into mechanisms through which specific changes in
genome transcripts and regulation induce changes in proteins,
pathways, organelles, cellular and tissue functions, morphology and
ultimately in phenotype.
Topics reviewed include investigations in genome architecture, gene
structure, gene regulation epigenetic modifications and function of
organelles including mitochondria, and the endosome lysosome
system. New insights into neurodevelopment and neurobehavioral
disorders gained through functional genomic research are presented.
Aspects of genomic studies in complex common diseases are reviewed.
Molecular genetic variations and aberrations in cellular mechanisms
involved in protein quality surveillance play a role in late onset
diseases and one chapter deals with this topic. Molecular analyses
of genes and proteins continue to shed light on the pathogenesis of
malformation syndromes and specific examples of such studies are
presented.
There is growing evidence that late onset disorders such as
Parkinson disease, are frequently the end result of defects in
functioning of components in different pathways and examples of
these are discussed. There is evidence that genetic variation
determines differences in response to environmental insults.
Genetic variations in complement factor genes are an example of
this and are discussed in the context of macular degeneration and
pathogenesis of hemolytic uremic syndrome in response exposure to E
coli Shiga toxin. In the final chapter the author briefly
summarizes key features of the cascade of events that constitute
functional genomics.
This book is meant to be a companion volume for the ACS Symposium
Series Book entitled Nuts and Bolts of Chemical Education Research.
In the Nuts and Bolts book (edited by Diane M. Bunce and Renee
Cole), readers were presented with information on how to conduct
quality chemical education research. In the Myth book, exemplars of
chemical education research are featured. In the cases where the
chapter in the book is describing research that has already been
published (typically in the Journal of Chemical Education),
additional information is provided either in terms of research
questions investigated that were not reported in the published
article or background information on decisions made in the research
that helped the investigation. The main focus of this type of
discussion is to engage the reader in the reality of doing chemical
education research including a discussion of the authors'
motivation. It is expected that these two books could be used as
textbooks for graduate chemical education courses showing how to do
chemical education research and then providing examples of quality
research.
The remarkable developments in differential topology and how these
recent advances have been applied as a primary research tool in
quantum field theory are presented here in a style reflecting the
genuinely two-sided interaction between mathematical physics and
applied mathematics. The author, following his previous work
(Nash/Sen: Differential Topology for Physicists, Academic Press,
1983), covers elliptic differential and pseudo-differential
operators, Atiyah-Singer index theory, topological quantum field
theory, string theory, and knot theory. The explanatory approach
serves to illuminate and clarify these theories for graduate
students and research workers entering the field for the first
time.
Key Features
* Treats differential geometry, differential topology, and quantum
field theory
* Includes elliptic differential and pseudo-differential operators,
Atiyah-Singer index theory, topological quantum field theory,
string theory, and knot theory
* Tackles problems of quantum field theory using differential
topology as a tool
This book describes modern techniques for reducing the level of
airborne noise through the introduction of sound radiated by
additional secondary sources, bringing together the results of
contemporary research in this area. It is the combination of the
physical properties of sound fields and modern digital signal
processing technology that has made the active control of sound a
practical proposition in a number of important applications. The
book covers both these aspects of the subject, initially at a
fundamental level, and then in detail in later chapters. The
structure of the book is such that it should be suitable for both
those seeking a basic understanding of the subject and as a
reference for researchers in the field. One of the key features of
the work is thus the unified presentation of material from the two
disciplines of acoustics and signal processing.
In the past, the stability of milk and milk products was the
primary consideration, but this is no longer the principal
objective due to the evolution of modern sanitary practices as well
as pasteurization. Today, the manufacture of dairy products of
consistently good flavor and texture is crucial. In previous flavor
studies, researchers identified hundreds of volatile compounds,
with little or no attention paid to their sensory contribution to
overall flavor of dairy products. The availability of powerful
chromatographic separation techniques like high resolution gas
chromatography in combination with mass spectrometry and olfactory
detection ports have revolutionized the work on characterization of
dairy flavor. This along with recent developments in sensory
methods and our increased knowledge about the genomics of diary
culture organisms have allowed great advancements in our
understanding of dairy flavor chemistry. Flavor of Dairy Products
covers the evolution of dairy flavor research and presents updated
information in the areas of instrumental analysis, biochemistry,
processing and shelf-life issues related to the flavor of dairy
products.
Flora of North America brings together for the first time ever in a
concise and easy to understand format information on all of the
plants growing spontaneously in North America north of Mexico.
Volume 24 of Flora North America is one of two volumes on grasses
to be published in this series (Volume 25, though it follows
sequentially, was published in 2003). Together they will provide a
comprehensive, authoritative, illustrated account of this important
group of plants. Most of the species treated are either native to
North America north of Mexico or are introduced species that are
now established in the region, but there are many that do not fit
into these categories. Among the additional species are several
that the USDA has identified as major weed threats; and others that
are known only as cultivated plants, some being cultivated for
their ornamental value, others as sources for human food or animal
forage. For instance, volume 24 includes such ecologically
important genera as Elymus (wheatgrasses), Poa (bluegrasses), and
Festuca (fescues), economically important species such as Triticum
(wheat), Hordeum (barley), Oryza (rice), and Zizania (wild rice),
several ornamental species, including some bamboos, and noxious
weeds such as Elymus repens (quackgrass), and Bromus tectorum
(cheatgrass).
The volume includes identification keys, descriptions, line
drawings, and ecological characteristics for each of the species;
distribution maps for the native and established species; and a
list of commonly encountered synonyms for the accepted names. The
treatments, each of which has been extensively reviewed, are based
on a combination of original observations and critical review of
the literature.
This book focuses on broadly defined areas of chemical information
science- with special emphasis on chemical informatics- and
computer-aided molecular design. The computational and
cheminformatics methods discussed, and their application to drug
discovery, are essential for sustaining a viable drug development
pipeline. It is increasingly challenging to identify new chemical
entities and the amount of money and time invested in research to
develop a new drug has greatly increased over the past 50 years.
The average time to take a drug from clinical testing to approval
is currently 7.2 years. Therefore, the need to develop predictive
computational techniques to drive research more efficiently to
identify compounds and molecules, which have the greatest
likelihood of being developed into successful drugs for a target,
is of great significance. New methods such as high throughput
screening (HTS) and techniques for the computational analysis of
hits have contributed to improvements in drug discovery efficiency.
The SARMs developed by Jurgen and colleagues have enabled display
of SAR data in a more transparent scaffold/functional SAR table.
There are many tools and databases available for use in applied
drug discovery techniques based on polypharmacology. The
cheminformatics approaches and methodologies presented in this
volume and at the Skolnik Award Symposium will pave the way for
improved efficiency in drug discovery. The lectures and the
chapters also reflect the various aspects of scientific enquiry and
research interests of the 2015 Herman Skolnik award recipient.
The history of life is a nearly four billion year old story of
transformative change. This change ranges from dramatic macroscopic
innovations such as the evolution of wings or eyes, to a myriad of
molecular changes that form the basis of macroscopic innovations.
We are familiar with many examples of innovations (qualitatively
new phenotypes that can provide a critical advantage) but have no
systematic understanding of the principles that allow organisms to
innovate. This book proposes several such principles as the basis
of a theory of innovation, integrating recent knowledge about
complex molecular phenotypes with more traditional Darwinian
thinking. Central to the book are genotype networks: vast sets of
connected genotypes that exist in metabolism and regulatory
circuitry, as well as in protein and RNA molecules. The theory can
successfully unify innovations that occur at different levels of
organization. It captures known features of biological innovation,
including the fact that many innovations occur multiple times
independently, and that they combine existing parts of a system to
new purposes. It also argues that environmental change is important
to create biological systems that are both complex and robust, and
shows how such robustness can facilitate innovation. Beyond that,
the theory can reconcile neutralism and selectionism, as well as
explain the role of phenotypic plasticity, gene duplication,
recombination, and cryptic variation in innovation. Finally, its
principles can be applied to technological innovation, and thus
open to human engineering endeavours the powerful principles that
have allowed life's spectacular success.
This book addresses one of the most challenging problems that
plagues the environmental field today-subsurface contamination. The
past three decades have ushered in various methods for removal of
organic and inorganic contaminants from the subsurface to varying
degrees of effectiveness. Because of the site-to-site variability
in the nature of contamination characteristics, the pattern of
waste disposal and accidental releases, the site characteristics
and thus contaminant behavior, and hydrologic conditions,
predicting the effectiveness of one treatment method over another
is a daunting task. Field demonstration of innovative technologies
is a key step in their development, however, only after successful
scale-up from laboratory testing. This book features chapters
written by researchers who have linked laboratory- and field-scales
in efforts to find creative, cost-effective methods for prediction
of successful remediation of contaminated soil and ground water.
State-of-the-art technologies using physicochemical removal methods
and biological methods are discussed in the context of not only
their effectiveness in remediating organic and inorganic wastes
from various subsurface environments but also in terms of useful
flask-scale methods for measuring and predicting their field-scale
effectiveness. Chapters address sorption and hydrolysis of
pesticides by organoclays, use of Fentons agents to destroy
chlorinated solvents removed from the subsurface by granulated
activated carbon, methanol flushing as a means of removing
toxaphene from soils, natural attenuation as a method for
effectiveness of remediation metals and biodegrading acid-mine
drainage constituents, and biodegradation ofradiologically
contaminated soils. Also addressed in this book are current and
future methods of assessing microbiological activity potential and
diversity and of modeling biodegradation, contaminant flux, and
gaseous transport in the subsurface.
Ethicists and psychologists have become increasingly interested in
the development of virtue in recent years, approaching the topic
from the perspectives of virtue ethics and developmental psychology
respectively. Such interest in virtue development has spread beyond
academia, as teachers and parents have increasingly striven to
cultivate virtue as part of education and child-rearing. Looking at
these parallel trends in the study and practice of virtue
development, the essays in this volume explore such questions as:
How can philosophical work on virtue development inform
psychological work on it, and vice versa? How should we understand
virtue as a dimension of human personality? What is the
developmental foundation of virtue? What are the evolutionary
aspects of virtue and its development? How is virtue fostered? How
is virtue exemplified in behavior and action? How is our conception
of virtue influenced by context and by developmental and social
experiences? What are the tensions, impediments and prospects for
an integrative field of virtue study? Rather than centering on each
discipline, the essays in this volume are orgnaized around themes
and engage each other in a broader dialogue. The volume begins with
an introductory essay from the editors that explains the full range
of philosophical and empirical issues that have surrounded the
notion of virtue in recent years.
The role of chance changed in the nineteenth century, and American
literature changed with it. Long dismissed as a nominal concept,
chance was increasingly treated as a natural force to be managed
but never mastered. New theories of chance sparked religious and
philosophical controversies while revolutionizing the sciences as
probabilistic methods spread from mathematics, economics, and
sociology to physics and evolutionary biology. Chance also became
more visible in everyday life as Americans struggled to control its
power through weather forecasting, insurance, game theory,
statistics, military science, and financial strategy. Uncertain
Chances shows how the rise of chance shaped the way
nineteenth-century American writers faced questions of doubt and
belief. Poe in his detective fiction critiques probabilistic
methods. Melville in Moby-Dick and beyond struggles to vindicate
moral action under conditions of chance. Douglass and other African
American authors fight against statistical racism. Thoreau learns
to appreciate the play between nature's randomness and order.
Dickinson works faithfully to render poetically the affective
experience of chance-surprise. These and other nineteenth-century
writers dramatize the inescapable dangers and wonderful
possibilities of chance. Their writings even help to navigate
extremes that remain with us today-fundamentalism and relativism,
determinism and chaos, terrorism and risk-management, the rational
confidence of the Enlightenment and the debilitating doubts of
modernity.
In this book, Chris Eliasmith presents a new approach to
understanding the neural implementation of cognition in a way that
is centrally driven by biological considerations. He calls the
general architecture that results from the application of this
approach the Semantic Pointer Architecture (SPA), based on the
Semantic Pointer Hypothesis. According to this hypothesis,
higher-level cognitive functions in biological systems are made
possible by semantic pointers. These pointers are neural
representations that carry partial semantic content and can be
built up into the complex representational structures necessary to
support cognition. The SPA architecture demonstrates how neural
systems generate, compose, and control the flow of semantics
pointers. Eliasmith describes in detail the theory and empirical
evidence supporting the SPA, and presents several examples of its
application to cognitive modeling, covering the generation of
semantic pointers from visual data, the application of semantic
pointers for motor control, and most important, the use of semantic
pointers for representation of language-like structures, cognitive
control, syntactic generalization, learning of new cognitive
strategies, and language-based reasoning. He agues that the SPA
provides an alternative to the dominant paradigms in cognitive
science, including symbolicism, connectionism, and dynamicism.
