Strongly interacting (QCD) matter is expected to exhibit a multifaceted phase structure: a hadron gas at low temperatures, a quark-gluon plasma at very high temperatures, nuclear matter in the low-temperature and high-density region, color superconductors at high densities. Most of the conjectured phases cannot yet be scrutinized by experiments but are based on model calculations. This monograph investigates the phases of QCD using a nonlocal covariant extension of the Nambu und Jona-Lasinio (NJL) model. This allows one to take into account the running of the QCD coupling strength at high and instanton physics at low energy scales. Gluon dynamics is implemented at finite temperatures and densities by coupling the nonlocal NJL model to a gluonic background field (expressed in terms of the Polyakov loop P). The thermodynamics of the resulting PNJL model describes both the chiral and the color-deconfinement transition. We obtain results in mean-field approximation, and extend them by including mesonic contributions to thermodynamic quantities. The phase-diagram region of finite density is investigated. A derivation of the nonlocal PNJL model from QCD first principles is also given.

Suitable for upper-level undergraduates and graduate students, this work explores the discovery of radioactivity, properties and nature of radiation, absorption and ionization, and changes occurring in radioactive bodies. Additional topics include radioactivity in the atmosphere, ultimate products of radioactive change, and electrical theory of the nature of matter. 1904 edition.

These works are recommended for those with a totally open mind, who seek to find only the truth of specie man's ultimate mental and physical development into the highest and noblest realms of thought and activity, through the development of the Christ of the self in a thorough honest research manner.
Following this line of thought, which only the individual can give, backed by the action it requires from that individual, is the only system available to implement the depth of democracy which each and every person on earth holds close to their heart.
Within these pages lies the secret of continuous life without end, total abundance, absolute wealth, power beyond your ability to dream, and the knowledge to freedom for the self, along with every person in the world.
Implementation into self of this knowledge is that which can set you and all man kind free.
Lawrence Hazlewood

The contents of the book: Bright Stars, Bright Universe: Advancing Civilization by Colonization of the Solar System and the Stars using a Fast Quark Drive include: 1.A description of the current state of the earth showing that an unavoidable decline in human civilization is inevitable without a major reduction in population and a major initiative to explore and colonize the Solar system. 2.A description of the major features of travel to other stars (and galaxies) at speeds such as 5,000c (5,000 times the speed of light) and 30,000c. We show that there is no limit to starship speeds so speeds of 1,000,000c, and above, are possible to travel to other galaxies. 3.A step by step program for space exploration and colonization (differing from other, short-range proposals) that is the most practical and cost effective approach to large-scale colonization of other planets and moons. 4.A description of the major features of faster-than-light travel and a new mechanism to break the light speed barrier that does not require a massive amount of resources that is beyond the capabilities of our current civilization. 5.The mechanism will be based on a quark drive using accelerated quark-gluon plasma rings to propel the starship. Quarks have complex spatial momentum in Blaha s theory of the Standard Model and thus can give a starship a complex thrust (and thereby a complex acceleration and velocity) that will enable it to go around the speed of light which is a real number. The quark-gluon plasma rings will be generated by creating macroscopic amounts of quark-gluon plasma via the high energy collision of heavy ions such as U238 atoms. Current circular accelerators are creating quark-gluon plasmas in very small quantity. Creating macroscopic amounts of such plasma is a major research challenge. 6.Starship occupants will not experience unacceptable acceleration forces. However, they will have to travel in suspended animation due to starship time contraction (yes contraction) at ultrahigh speeds. (The passage of time is accelerated on starships traveling at speeds much greater than the speed of light. Time will pass on a starship traveling at 5,000c at a rate 5,000 times the passage of time on earth. So a one year period on earth will appear to be 5,000 years on the starship. However in suspended animation starship occupants would sleep through the trip. If they return the same way, then they would find that, in two years of earth time, they would have only aged the amount of time spent at the starship s destination.) Suspended animation would keep the biological clock of starship passengers roughly in sync with earth time. Developing suspended animation for humans for long periods of time is also a major research challenge. Besides being a requirement for starship travel it will have major medical value on earth. 7.The proposed starship can be built with a major world-wide R&D effort in probably 30 years. Its cost will be high. There are major technical challenges. But there will be significant benefits on earth from the knowledge gained, and success will open the known universe to Mankind and a glorious future. The alternative is a declining civilization with declining resources.

Tomographic imaging devices, such as PET/SPECT, suffer from their low resolution capabilities and produce images having partial volume error and non- uniform reconstructed resolution across their field of view. This results in quantification errors and hinders the optimum use of these images in diagnostic and therapeutic applications. This writing provides a detailed insight into the tomographic imaging, image reconstruction methods and proposes recovery methods for non-uniform resolution and partial volume errors in Tomographic image reconstruction. Specifically, it details the resolution characteristics of median root based priors and their comparison with the standard quadratic priors and in general discusses their implementation for the recovery of above mentioned errors in reconstructed images for histogram and List-Mode data reconstruction methods. Readers in medical imaging and image reconstruction methods may benefit from this book including an understanding of basic imaging physics and mathematics.

Charged-particle accelerators are the basic tools of high-energy physics, the science of fundamental properties of matter. Besides, a large number of synchrotron radiation sources are used world-wide for research and industrial purposes. Effective operation of modern accelerator facilities is almost impossible without precise and reliable diagnostics of particle beams. A review of instruments and methods of particle beam diagnostics in accelerators is given in this book. Physical principles of operation of beam diagnostic instruments of various types, such as contact probes, synchrotron radiation monitors and electromagnetic pickups are described. Methods of signal analysis are also reviewed. Bases of design and operation of beam diagnostic instruments are surveyed using particular examples. Methods of processing of the data obtained from beam diagnostic systems are analyzed in detail. Principles of a feedback usage in the particle accelerators are given. The book is intended for scientists and engineers occupied with the development and operation of particle accelerators, and can also be useful for the students training in particle beam physics and accelerator technique.

This book describes Monte Carlo simulations of the processes in proportional counters used for absolute measurements of activity concentration of Krypton-85. It also offers a method for estimation of counting losses based on the results from Monte Carlo simulations. Each part of the book focuses on different aspects of the operation and/or modeling of proportional counters. Chapter I describes the experimental method for absolute measurement of activity concentration of Krypton-85 developed at LNHB/CEA-Saclay with emphasis on the origin of counting losses and their estimation. Chapter II describes in detail the techniques used in the development of the Monte Carlo code and the code itself. Chapter III is devoted to the process of gas multiplication. It contains a systematic study of the process of gas multiplication in cylindrical proportional counters and offers a discussion on the behavioral differences of the gas multiplication process in uniform and non uniform electric fields. The method for estimation of counting losses is described in the last chapter with attention on the individual contribution of different phenomena to counting losses and their combined effect.

With his knack for translating science into understandable, anecdotal prose and his trademark dry humor, award-winning science writer Charles Seife presents the first narrative account of the history of fusion for general readers in more than a decade. Tracing the story from its beginning into the twenty-first century, Sun in a Bottle reveals fusion's explosive role in some of the biggest scientific scandals of all time. Throughout this journey, he introduces us to the daring geniuses, villains, and victims of fusion science. With the giant international fusion project ITER (International Thermonuclear Experimental Reactor) now under construction, it's clear that the science of wishful thinking is as strong as ever. This book is our key to understanding why.

From flat-panel televisions to thermonuclear fusion for energy production, plasmas currently have numerous and wide applications in sciences and industry. A diversity of plasma diagnostics is available to physicists and engineers to measure and control plasma parameters. Among them, the Langmuir probe is the most inexpensive and most popular instrument and method. The Langmuir probe is a small electrode which is submerged in plasma in order to measure the probe current-voltage characteristic. The same characteristic is processed further to derive the electron and ion concentration, the electron distribution function, and the plasma potential at the probe location. Langmuir probe diagnostics afford rapid measurements of the electron distribution function and plasma potential at a good time resolution, 10-8 seconds in a wide range of plasma densities 10+3 - 10+14 cm-3, and the electron energy from the room temperature to hundreds of electron-volts - qualities which are essential for researchers. In view of these facts, Langmuir probe diagnostics are applied very frequently to measuring plasma parameters. This book will be useful in teaching plasma diagnostics to undergraduate and graduate students in plasma physics courses. And it will also serve as a practical reference manual for physicists and engineers working in the growing area of plasma physics. The reader of this book will learn what kind of plasma parameters the Langmuir probe can measure, how to develop the probe diagnostics for specific cases, and how the probe data obtained should be processed to deduce reliable plasma parameters. In this book, the reader can find not only the basic physics information important to understanding the principles of probe operation, but also how the "real" probe disturbs plasma, and how it is possible to reconstruct undisturbed plasma parameters with available probe data.

A high-level, rigorous, and technical treatment of modern particle physics, this book was written by a well-known professor at Harvard University who conducts ongoing research programs in several areas of theoretical particle physics.
Introductory chapters examine Noether's theorem, the electron, and SU (3) quark models. Subsequent chapters explore weak decays of light hadrons, effective low-momentum field theories, the transformation law for baryons, mode counting, effective field theories, and the renormalization group. Two helpful indexes review dimensional regularization and background field gauge. In addition to its value as a text for advanced undergraduate and graduate students of physics, this volume also serves as a reference for professionals.

Born in colonial New Zealand, Ernest Rutherford grew up on the frontier a different world from Cambridge, to which he won a scholarship at the age of twenty-four. His work revolutionized modern physics. Among his discoveries were the orbital structure of the atom and the concept of the "half-life" of radioactive materials. Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces forces, as Rutherford himself predicted, that would bring us the atomic bomb. In Richard Reeves's hands, Rutherford comes alive, a ruddy, genial man and a pivotal figure in scientific history.

Radiation detection technology has international attention for its importance in solving issues such as nuclear proliferation, homeland security, and studying physics from the grand scale of the cosmos to the diminutive world of subatomic particles. The last decade has produced myriad exciting developments in materials, designs, and data processing. This book examines performance enhancements in ionization chambers for radiation detection applications, suggesting advanced designs to provide new capabilities. High-pressure xenon ionization chambers are the focus of this work, although the techniques discussed are applicable to a broad range of radiation detectors. A new electrode design is proposed, and the reader is walked through an optimization study, position-sensing methodology, and detailed techniques to understand performance limitations and potential improvements. This book will be of interest to expert scientists and engineers as a presentation of novel techniques, but the content is also valuable as a step-by-step guide for newcomers to the field of radiation detection interested in learning how to design, optimize, and characterize detectors.

What if a doctor could stop cancer by targeting a single malignant cell before it multiplied? Imagine a paper-thin "power suit" that could keep you warm on a winter day? What about a computer that connects directly with your thoughts? In this groundbreaking exploration of the future of nanotechnology, Ted Sargent reveals how all disciplines of science, from medicine to microchips, are converging to create materials using the tiniest scale possible -- molecule by molecule. And instead of trying to overcome the natural world, nanotech takes its every move from the perfect, elegant structure of nature itself. Its potential is seemingly endless, with practical implications that will revolutionize the way we live, work, and play. In an age when science often evokes more fear than faith, when the potential for superviruses and diabolical cloning looms in our consciousness, Sargent enthusiastically illuminates nanotech's positive possibilities. By working with the tiniest building blocks in nature, pioneering scientists will drastically improve the quality of life for all of us.

This text on optics for graduate students explains how to determine material properties and parameters for inaccessible substrates and unknown films as well as how to measure extremely thin films. Its 14 case studies illustrate concepts and reinforce applications of ellipsometry -- particularly in relation to the semiconductor industry and to studies involving corrosion and oxide growth.
"A User's Guide to Ellipsometry" will enable readers to move beyond limited turn-key applications of ellipsometers. In addition to its comprehensive discussions of the measurement of film thickness and optical constants in film, it also considers the trajectories of the ellipsometric parameters Del and Psi and how changes in materials affect parameters. This volume also addresses the use of polysilicon, a material commonly employed in the microelectronics industry, and the effects of substrate roughness. Three appendices provide helpful references.
