Principles of Nucleic Acid Structure, Second Edition, provides the most complete and concise summary of underlying principles and approaches to studying nucleic acid structure, including discussions of X-ray crystallography, NMR, molecular modelling and databases. The book's focus is on a survey of structures that are especially important for biomedical research and pharmacological applications. This updated edition includes the latest advances relevant to recognition of DNA and RNA by small molecules and proteins, including sections on RNA folding, ribosome structure and antibiotic interactions, DNA quadruplexes, DNA and RNA protein complexes and short interfering RNA (siRNA). This reference is a must-have for those seeking an authoritative, comprehensive and up-to-date source on all aspects of nucleic acid structure, from basic first principles to details of recent research results.
By incorporating extensive student input and innovative teaching
methodologies, this book aims to make the process of learning
quantum field theory easier, and thus more rapid, profound, and
efficient, for both students and instructors. Comprehensive
explanations are favored over conciseness, every step in
derivations is included, and 'big picture' overviews are provided
throughout.
The progress in nuclear magnetic resonance (NMR) spectroscopy that took place during the last several decades is observed in both experimental capabilities and theoretical approaches to study the spectral parameters. The scope of NMR spectroscopy for studying a large series of molecular problems has notably broadened. However, at the same time, it requires specialists to fully use its potentialities. This is a notorious problem and it is reflected in the current literature where this spectroscopy is typically only used in a routine way. Also, it is seldom used in several disciplines in which it could be a powerful tool to study many problems. The main aim of this book is to try to help reverse these trends. This book is divided in three parts dealing with 1)
high-resolution NMR parameters; 2) methods for understanding
high-resolution NMR parameters; and 3) some experimental aspects of
high-resolution NMR parameters for studying molecular structures.
Each part is divided into chapters written by different specialists
who use different methodologies in their work. In turn, each
chapter is divided into sections. Some features of the different
sections are highlighted: it is expected that part of the
readership will be interested only in the basic aspects of some
chapters, while other readers will be interested in deepening their
understanding of the subject dealt with in them. Contributions by specialists who use the discussed methodologies in their everyday work
This book aims to introduce the reader to basic concepts concerning matter physics, describing how fundamental properties of atoms, molecules and condensed matter are affected by properties of electrons and by their interaction with electromagnetic waves.As an introductory text on basic properties of matter, the contents are designed for undergraduate students in electrical engineering. It is based on the lectures given by the author for over a decade on Matter Physics and Solid State Physics. It focuses on electronic properties to discuss the structure, electrical and optical properties of matter, and is organized into six chapters.The first chapter is a short review of the basic properties of electromagnetic waves, giving the basic concepts related to wave propagation to be handled easily to understand the subsequent topics. The next chapter on quantum mechanics helps to understand the quantum properties of matter using the simplest formalizations. Chapter 3 introduces the core of the book by using quantum mechanics to describe the electronic properties of the atom. Then, after atomic bonding, molecules and condensed matter are discussed before approaching the structural properties of crystal and soft matter. The following chapters (4 and 5) are then devoted to electrical properties and optical properties and address the main topics related to solid state and semiconductor physics as well as light-matter interaction. The final chapter 6, deals with the basic properties of lasers, due to the relevance of light sources in everyday life, and their widespread use in all branches of engineering.
Hulchul: The Common Ingredient of MotionMotionMotionMotion and Time Author, Sohan Jain, proposes the following in the book: Instants of Motion, Instants of Time and Time Outage: Just as time has instants of time, motion has instants of motion, too. Instants of time and motion can be divided into three classes: pure instants of time, pure instants of motion, and composite instants of time and motion. The sequences of the three types of instants are interspersed into a single sequence of their occurrences. A body does not experience time during pure instants of motion, a phenomenon we will call time outage -the cause of time dilation. Time outage is not continuous; it is intermittent. Internal and external motion of a body and their inheritance: Each body has, generally, two kinds of motions: internal motion and external motion. A body goes, wherever its outer bodies go. An inner body inherits external motion of its outer bodies. An outer body inherits internal motion of its inner bodies. Photons and light do not inherit motion; may be, this is why their motions are independent of their sources. Prime ticks, the building blocks of time and any motion: Motion of a common body is not continuous; it is intermittent. Any kind of motion is perceived to be made of discrete, indivisible tiny movements, called prime ticks (p-ticks). P-ticks are to motion what elementary particles are to matter or what photons are to light. There is time only because there is motion. Prime ticks are events and imply motion. Events have concurrency, which implies time. Total concurrency hulchul, a universal constant: Concurrency events of external and internal p-ticks of a body are precisely the instants of motion and time. The sum of the two is called the total concurrency hulchul (c-hulchul). Total c-hulchul is the same for all bodies. The proposed theory possibly explains: Why a particle accelerator works. Why atoms have compartmentalized internal structure. Why lighter bodies, such as elementary particles and photons, have wavy straight motion rather than straight motion. The theory predicts: The sharing of an electron by two atoms is not continuous; it alternates between the two atoms.
Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras.
Our understanding of subatomic particles developed over many years, although a clear picture of the different particles, their interactions and their inter-relationships only emerged in the latter part of the twentieth century. The first ""subatomic particles"" to be investigated were those which exhibit readily observable macroscopic behavior, specifically these are the photon, which we observe as light and the electron, which is manifested as electricity. The true nature of these particles, however, only became clear within the last century or so. The development of the Standard Model provided clarification of the way in which various particles, specifically the hadrons, relate to one another and the way in which their properties are determined by their structure. The final piece, perhaps, of the final model, that is the means by which some particles acquire mass, has just recently been clarified with the observation of the Higgs boson. Since the 1970s it has been known that the measured solar neutrino flux was inconsistent with the flux predicted by solar models. The existence of neutrinos with mass would allow for neutrino flavor oscillations and would provide an explanation for this discrepancy. Only in the past few years, has there been clear experimental evidence that neutrinos have mass. The description of particle structure on the basis of the Standard Model, along with recent discoveries concerning neutrino properties, provides us with a comprehensive picture of the properties of subatomic particles. Part I of the present book provides an overview of the Standard Model of particle physics including an overview of the discovery and properties of the Higgs boson. Part II of the book summarizes the important investigations into the physics of neutrinos and provides an overview of the interpretation of these studies.
This book is based on a set of 18 class-tested lectures delivered to fourth-year physics undergraduates at Grifi th University in Brisbane, and the book presents new discoveries by the Nobel-prize winning LIGO collaboration. The author begins with a review of special relativity and tensors and then develops the basic elements of general relativity (a beautiful theory that unifies special relativity and gravitation via geometry) with applications to the gravitational deflection of light, global positioning systems, black holes, gravitational waves, and cosmology. The book provides readers with a solid understanding of the underlying physical concepts; an ability to appreciate and in many cases derive important applications of the theory; and a solid grounding for those wishing to pursue their studies further. General Relativity: An Introduction to Black Holes, Gravitational Waves, and Cosmology also connects general relativity with broader topics. There is no doubt that general relativity is an active and exciting field of physics, and this book successfully transmits that excitement to readers.
Comprises four parts, the first of which provides an overview of the topics that are developed from fundamental principles to more advanced levels in the other parts. Presents in the second part an in-depth introduction to the relevant background in molecular and cellular biology and in physical chemistry, which should be particularly useful for students without a formal background in these subjects. Provides in the third part a detailed treatment of microscopy techniques and optics, again starting from basic principles. Introduces in the fourth part modern statistical approaches to the determination of parameters of interest from microscopy data, in particular data generated by single molecule microscopy experiments. Uses two topics related to protein trafficking (transferrin trafficking and FcRn-mediated antibody trafficking) throughout the text to motivate and illustrate microscopy techniques
All living matter is comprised of cells, small compartments isolated from the environment by a cell membrane and filled with concentrated solutions of various organic and inorganic compounds. Some organisms are single-cell, where all life functions are performed by that cell. Others have groups of cells, or organs, specializing in one particular function. The survival of the entire organism depends on all of its cells and organs fulfilling their roles. While the cells are studied by different sciences, they are seen differently by biologists, chemists, or physicists. Biologists concentrate their attention on cell structure and function. What the cells consists of? Where are its organelles? What function each organelle fulfils? From a chemists' point of view, a cell is a complex chemical reaction chamber where various molecules are synthesized or degraded. The main question is how these, sometimes very complicated chains of reactions are controlled. Finally, from a physics standpoint, some of the fundamental questions are about the physical movement of all these molecules between organelles within the cell, their exchange with the extracellular medium, as well as electrical phenomena resulting from such transport. The aim of this book is to look into the basic physical phenomena occurring in cells. These physical transport processes facilitate chemical reactions in the cell and various electrical effects, and that in turn leads to biological functions necessary for the cell to satisfy its role in the mother organism. Ultimately, the goals of every cell are to stay alive and to fulfill its function as a part of a larger organ or organism. The first volume of this book is an inventory of physical transport processes occurring in cells while this second volume provides a closer look at how complex biological and physiological cell phenomena result from these very basic physical processes.
For decades, the surface-plasmon-polariton wave guided by the
interface of simple isotropic materials dominated the scene.
However, in recent times research on electromagnetic surface waves
guided by planar interfaces has expanded into new and exciting
areas. In the 1990's research focused on advancing knowledge of the
newly discovered Dyakonov wave. More recently, much of the surface
wave research is motivated by the proliferation of nanotechnology
and the growing number of materials available with novel
properties. This book leads the reader from the relatively simple
surface-plasmon-polariton wave with isotropic materials to the
latest research on various types of electromagnetic surface waves
guided by the interfaces of complex materials enabled by recent
developments in nanotechnology. This includes: Dyakonov waves
guided by interfaces formed with columnar thin films, Dyakonov-Tamm
waves guided by interfaces formed with sculptured thin films, and
multiple modes of surface-plasmon-polariton waves guided by the
interface of a metal and a periodically varying dielectric
material.
Biochemistry of Lipids, Lipoproteins and Membranes, Seventh Edition serves as a comprehensive, general reference book for scientists and students studying lipids, lipoproteins and membranes. Here, across 19 chapters, leaders in the field summarize fundamental concepts, recent research developments, data analysis, and implications for human disease and intervention. Topics discussed include lipid biology in both prokaryotes and eukaryotes, fatty acid synthesis, desaturation and elongation, and pathways leading to synthesis of complex phospholipids, sphingolipids and their structural variants. Chapters also examine how bioactive lipids are involved in cell signaling, with an emphasis on disease implications and pathological consequences. As the field advances, each chapter in this new edition has been fully revised to address emerging topics, with all-new coverage of lipid droplets and their role as regulatory organelles for energy homeostasis, as well as their relationship to obesity, liver disease and diabetes. Evolving research in fatty acid handling and storage in eukaryotes is also discussed in-depth, with new sections addressing fatty acid uptake, activation and lipolysis.
A glass is disordered material like a viscous liquid and behaves mechanically like a solid. A glass is normally formed by supercooling the viscous liquid fast enough to avoid crystallization, and the liquid-glass transition occurs in diverse manners depending on the materials, their history, and the supercooling processes, among other factors. The glass transition in colloids, molecular systems, and polymers is studied worldwide. This book presents a unified theory of the liquid-glass transition on the basis of the two band model from statistical quantum field theory associated with the temperature Green's function method. It is firmly original in its approach and will be of interest to researchers and students specializing in the glass transition across the physical sciences.
