Genomics: The Science and Technology Behind the Human Genome Project (by Charles R. Cantor and Cassandra L. Smith)

NASA Astrophysics Data System (ADS)

Serra, Reviewed By Martin J.

2000-01-01

Genomics is one of the most rapidly expanding areas of science. This book is an outgrowth of a series of lectures given by one of the former heads (CRC) of the Human Genome Initiative. The book is designed to reach a wide audience, from biologists with little chemical or physical science background through engineers, computer scientists, and physicists with little current exposure to the chemical or biological principles of genetics. The text starts with a basic review of the chemical and biological properties of DNA. However, without either a biochemistry background or a supplemental biochemistry text, this chapter and much of the rest of the text would be difficult to digest. The second chapter is designed to put DNA into the context of the larger chromosomal unit. Specialized chromosomal structures and sequences (centromeres, telomeres) are introduced, leading to a section on chromosome organization and purification. The next 4 chapters cover the physical (hybridization, electrophoresis), chemical (polymerase chain reaction), and biological (genetic) techniques that provide the backbone of genomic analysis. These chapters cover in significant detail the fundamental principles underlying each technique and provide a firm background for the remainder of the text. Chapters 7­9 consider the need and methods for the development of physical maps. Chapter 7 primarily discusses chromosomal localization techniques, including in situ hybridization, FISH, and chromosome paintings. The next two chapters focus on the development of libraries and clones. In particular, Chapter 9 considers the limitations of current mapping and clone production. The current state and future of DNA sequencing is covered in the next three chapters. The first considers the current methods of DNA sequencing - especially gel-based methods of analysis, although other possible approaches (mass spectrometry) are introduced. Much of the chapter addresses the limitations of current methods, including analysis of error in sequencing and current bottlenecks in the sequencing effort. The next chapter describes the steps necessary to scale current technologies for the sequencing of entire genomes. Chapter 12 examines alternate methods for DNA sequencing. Initially, methods of single-molecule sequencing and sequencing by microscopy are introduced; the majority of the chapter is devoted to the development of DNA sequencing methods using chip microarrays and hybridization. The remaining chapters (13-15) consider the uses and analysis of DNA sequence information. The initial focus is on the identification of genes. Several examples are given of the use of DNA sequence information for diagnosis of inherited or infectious diseases. The sequence-specific manipulation of DNA is discussed in Chapter 14. The final chapter deals with the implications of large-scale sequencing, including methods for identifying genes and finding errors in DNA sequences, to the development of computer algorithms for the interpretation of DNA sequence information. The text figures are black and white line drawings that, although clearly done, seem a bit primitive for 1999. While I appreciated the simplicity of the drawings, many students accustomed to more colorful presentations will find them wanting. The four color figures in the center of the text seem an afterthought and add little to the text's clarity. Each chapter has a set of additional reading sources, mostly primary sources. Often, specialized topics are offset into boxes that provide clarification and amplification without cluttering the text. An appendix includes a list of the Web-based database resources. As an undergraduate instructor who has previously taught biochemistry, molecular biology, and a course on the human genome, I found many interesting tidbits and amplifications throughout the text. I would recommend this book as a text for an advanced undergraduate or beginning graduate course in genomics. Although the text works though several examples of genetic and genome analysis, additional problem/homework sets would need to be developed to ensure student comprehension. The text steers clear of the ethical implications of the Human Genome Initiative and remains true to its subtitle The Science and Technology .

Speaking in Character: Voice Communication in Virtual Worlds

NASA Astrophysics Data System (ADS)

Wadley, Greg; Gibbs, Martin R.

This chapter summarizes 5 years of research on the implications of introducing voice communication systems to virtual worlds. Voice introduces both benefits and problems for players of fast-paced team games, from better coordination of groups and greater social presence of fellow players on the positive side, to negative features such as channel congestion, transmission of noise, and an unwillingness by some to use voice with strangers online. Similarly, in non-game worlds like Second Life, issues related to identity and impression management play important roles, as voice may build greater trust that is especially important for business users, yet it erodes the anonymity and ability to conceal social attributes like gender that are important for other users. A very different mixture of problems and opportunities exists when users conduct several simultaneous conversations in multiple text and voice channels. Technical difficulties still exist with current systems, including the challenge of debugging and harmonizing all the participants' voice setups. Different groups use virtual worlds for very different purposes, so a single modality may not suit all.

Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in [Formula: see text] collisions at [Formula: see text] = 5.02 and 13 TeV and in [Formula: see text] + Pb collisions at [Formula: see text] = 5.02 TeV, and compared to the results obtained for low-multiplicity [Formula: see text] collisions at [Formula: see text] = 2.76 TeV. These measurements aim to assess the collective nature of particle production. The measurements of multi-particle cumulants confirm the evidence for collective phenomena in [Formula: see text] + Pb and low-multiplicity [Formula: see text] collisions. On the other hand, the [Formula: see text] results for four-particle cumulants do not demonstrate collective behaviour, indicating that they may be biased by contributions from non-flow correlations. A comparison of multi-particle cumulants and derived Fourier harmonics across different collision systems is presented as a function of the charged-particle multiplicity. For a given multiplicity, the measured Fourier harmonics are largest in [Formula: see text], smaller in [Formula: see text] + Pb and smallest in [Formula: see text] collisions. The [Formula: see text] results show no dependence on the collision energy, nor on the multiplicity.

Non-axisymmetric ideal equilibrium and stability of ITER plasmas with rotating RMPs

NASA Astrophysics Data System (ADS)

Ham, C. J.; Cramp, R. G. J.; Gibson, S.; Lazerson, S. A.; Chapman, I. T.; Kirk, A.

The magnetic perturbations produced by the resonant magnetic perturbation (RMP) coils will be rotated in ITER so that the spiral patterns due to strike point splitting which are locked to the RMP also rotate. This is to ensure even power deposition on the divertor plates. VMEC equilibria are calculated for different phases of the RMP rotation. It is demonstrated that the off harmonics rotate in the opposite direction to the main harmonic. This is an important topic for future research to control and optimize ITER appropriately. High confinement mode (H-mode) is favourable for the economics of a potential fusion power plant and its use is planned in ITER. However, the high pressure gradient at the edge of the plasma can trigger periodic eruptions called edge localized modes (ELMs). ELMs have the potential to shorten the life of the divertor in ITER (Loarte et al 2003 Plasma Phys. Control. Fusion 45 1549) and so methods for mitigating or suppressing ELMs in ITER will be important. Non-axisymmetric RMP coils will be installed in ITER for ELM control. Sampling theory is used to show that there will be significant a {{n}\\text{coils}}-{{n}\\text{rmp}} harmonic sideband. There are nine coils toroidally in ITER so {{n}\\text{coils}}=9 . This results in a significant n  =  6 component to the {{n}\\text{rmp}}=3 applied field and a significant n  =  5 component to the {{n}\\text{rmp}}=4 applied field. Although the vacuum field has similar amplitudes of these harmonics the plasma response to the various harmonics dictates the final equilibrium. Magnetic perturbations with toroidal mode number n  =  3 and n  =  4 are applied to a 15 MA, {{q}95}≈ 3 burning ITER plasma. We use a three-dimensional ideal magnetohydrodynamic model (VMEC) to calculate ITER equilibria with applied RMPs and to determine growth rates of infinite n ballooning modes (COBRA). The {{n}\\text{rmp}}=4 case shows little change in ballooning mode growth rate as the RMP is rotated, however there is a change with rotation for the {{n}\\text{rmp}}=3 case.

Cantico Delle Creature: A microtonal original composition for soprano and string quartet to a text by St. Francis of Assisi, including analytical commentary

NASA Astrophysics Data System (ADS)

Sabol, Jason A.

Cantico delle Creature is an original piece of music for soprano and string quartet composed in 72 tone per octave equal temperament, dividing each semitone into six equal parts called twelfth-tones. This system of tuning makes it possible to combine just intonation and spectral principles based on the harmonic series with real imitation, modulation, and polyphony. Supplemental text discusses several aspects of microtonal structure and pedagogy, including the representation of the first 64 partials of the harmonic series in 72 tone equal temperament, performance of natural string harmonics, the relationship between interval size and vibration ratio, pitch to frequency conversion, and analysis of several passages in the musical score.

This chapter highlights methods for visualization and analysis of extracellular matrix (ECM) proteins, with particular emphasis on collagen type I, the most abundant protein in mammals. Protocols described range from advanced imaging of complex in vivo matrices to simple biochemical analysis of individual ECM proteins. The first section of this chapter describes common methods to image ECM components and includes protocols for second harmonic generation, scanning electron microscopy, and several histological methods of ECM localization and degradation analysis, including immunohistochemistry, Trichrome staining, and in situ zymography. The second section of this chapter details both a common transwell invasion assay and a novel live imaging method to investigate cellular behavior with respect to collagen and other ECM proteins of interest. The final section consists of common electrophoresis-based biochemical methods that are used in analysis of ECM proteins. Use of the methods described herein will enable researchers to gain a greater understanding of the role of ECM structure and degradation in development and matrix-related diseases such as cancer and connective tissue disorders. © 2018 Elsevier Inc.

BOOK REVIEW: Introduction to 3+1 Numerical Relativity

NASA Astrophysics Data System (ADS)

Gundlach, Carsten

2008-11-01

This is the first major textbook on the methods of numerical relativity. The selection of material is based on what is known to work reliably in astrophysical applications and would therefore be considered by many as the 'mainstream' of the field. This means spacelike slices, the BSSNOK or harmonic formulation of the Einstein equations, finite differencing for the spacetime variables, and high-resolution shock capturing methods for perfect fluid matter. (Arguably, pseudo-spectral methods also belong in this category, at least for elliptic equations, but are not covered in this book.) The account is self-contained, and comprehensive within its chosen scope. It could serve as a primer for the growing number of review papers on aspects of numerical relativity published in Living Reviews in Relativity (LRR). I will now discuss the contents by chapter. Chapter 1, an introduction to general relativity, is clearly written, but may be a little too concise to be used as a first text on this subject at postgraduate level, compared to the textbook by Schutz or the first half of Wald's book. Chapter 2 contains a good introduction to the 3+1 split of the field equations in the form mainly given by York. York's pedagogical presentation (in a 1979 conference volume) is still up to date, but Alcubierre makes a clearer distinction between the geometric split and its form in adapted coordinates, as well as filling in some derivations. Chapter 3 on initial data is close to Cook's 2001 LRR, but is beautifully unified by an emphasis on how different choices of conformal weights suit different purposes. Chapter 4 on gauge conditions covers a topic on which no review paper exists, and which is spread thinly over many papers. The presentation is both detailed and unified, making this an excellent resource also for experts. The chapter reflects the author's research interests while remaining canonical. Chapter 5 covers hyperbolic reductions of the field equations. Alcubierre's excellent presentation is less technical than Reula's 1998 LRR or the 1995 book by Gustafsson, Kreiss and Oliger, but covers the key ideas in application to the Einstein equations. The reviewer (admittedly riding a hobby-horse) would argue that the hyperbolicity of the ADM and BSSNOK equations should have been investigated without introducing a specific first-order reduction. Chapter 6 covers gauge problems in numerical black hole spacetimes, black hole excision, and apparent horizons. Like chapter 4 it is both exhaustive and pedagogical. Perhaps more space than necessary is given here to work the author was involved in, while the section on slice stretching could have been more detailed, given that there is no good overview in the literature. Chapter 7 on relativistic hydrodynamics is, quite simply, excellent. Among many other useful things it contains some elementary material on equations of state that is not written up at this level elsewhere, a good mini-introduction to weak solutions of conservation laws, and a brief review of imperfect fluids in GR (Israel--Stewart theory). This chapter complements Font's 2008 LRR. Chapter 8 on gravitational wave extraction provides a welcome pedagogical introduction to a topic in which the original research papers are less than inviting and where notation is not uniform. The mathematical techniques described here are in constant use in numerical relativity codes, but are never fully described in research papers. Chapter 9 on numerical methods covers finite difference and high-resolution shock capturing methods. It is similar in presentation to Leveque's 1992 book and Kreiss and Busenhart's 2001 book, but gives a good selection of that material, concisely presented. It certainly impresses the importance of convergence testing on the reader. Chapter 10 covers methods for spherically symmetric and axisymmetric spacetimes. The former is excellent, reflecting the author's recent research work. The axisymmetry section would have been better if it had been based on a formal Geroch reduction, the method that has been the key to recent progress. This book is bound to become a standard text for beginning graduate students. In an overview for this audience, I would have liked to see a little more detail on null slicings and on the conformal field equations, and brief introductions to the theory of elliptic equations and to pseudo-spectral and finite element methods. One may also regret the many typographical errors. Nevertheless, this excellent book fills a real gap, and will be hard to follow.

AgMIP Training in Multiple Crop Models and Tools

NASA Technical Reports Server (NTRS)

Boote, Kenneth J.; Porter, Cheryl H.; Hargreaves, John; Hoogenboom, Gerrit; Thornburn, Peter; Mutter, Carolyn

2015-01-01

The Agricultural Model Intercomparison and Improvement Project (AgMIP) has the goal of using multiple crop models to evaluate climate impacts on agricultural production and food security in developed and developing countries. There are several major limitations that must be overcome to achieve this goal, including the need to train AgMIP regional research team (RRT) crop modelers to use models other than the ones they are currently familiar with, plus the need to harmonize and interconvert the disparate input file formats used for the various models. Two activities were followed to address these shortcomings among AgMIP RRTs to enable them to use multiple models to evaluate climate impacts on crop production and food security. We designed and conducted courses in which participants trained on two different sets of crop models, with emphasis on the model of least experience. In a second activity, the AgMIP IT group created templates for inputting data on soils, management, weather, and crops into AgMIP harmonized databases, and developed translation tools for converting the harmonized data into files that are ready for multiple crop model simulations. The strategies for creating and conducting the multi-model course and developing entry and translation tools are reviewed in this chapter.

BOOK REVIEW: The Illustrated Wavelet Transform Handbook: Introductory Theory and Applications in Science, Engineering, Medicine and Finance

NASA Astrophysics Data System (ADS)

Ng, J.; Kingsbury, N. G.

2004-02-01

This book provides an overview of the theory and practice of continuous and discrete wavelet transforms. Divided into seven chapters, the first three chapters of the book are introductory, describing the various forms of the wavelet transform and their computation, while the remaining chapters are devoted to applications in fluids, engineering, medicine and miscellaneous areas. Each chapter is well introduced, with suitable examples to demonstrate key concepts. Illustrations are included where appropriate, thus adding a visual dimension to the text. A noteworthy feature is the inclusion, at the end of each chapter, of a list of further resources from the academic literature which the interested reader can consult. The first chapter is purely an introduction to the text. The treatment of wavelet transforms begins in the second chapter, with the definition of what a wavelet is. The chapter continues by defining the continuous wavelet transform and its inverse and a description of how it may be used to interrogate signals. The continuous wavelet transform is then compared to the short-time Fourier transform. Energy and power spectra with respect to scale are also discussed and linked to their frequency counterparts. Towards the end of the chapter, the two-dimensional continuous wavelet transform is introduced. Examples of how the continuous wavelet transform is computed using the Mexican hat and Morlet wavelets are provided throughout. The third chapter introduces the discrete wavelet transform, with its distinction from the discretized continuous wavelet transform having been made clear at the end of the second chapter. In the first half of the chapter, the logarithmic discretization of the wavelet function is described, leading to a discussion of dyadic grid scaling, frames, orthogonal and orthonormal bases, scaling functions and multiresolution representation. The fast wavelet transform is introduced and its computation is illustrated with an example using the Haar wavelet. The second half of the chapter groups together miscellaneous points about the discrete wavelet transform, including coefficient manipulation for signal denoising and smoothing, a description of Daubechies’ wavelets, the properties of translation invariance and biorthogonality, the two-dimensional discrete wavelet transforms and wavelet packets. The fourth chapter is dedicated to wavelet transform methods in the author’s own specialty, fluid mechanics. Beginning with a definition of wavelet-based statistical measures for turbulence, the text proceeds to describe wavelet thresholding in the analysis of fluid flows. The remainder of the chapter describes wavelet analysis of engineering flows, in particular jets, wakes, turbulence and coherent structures, and geophysical flows, including atmospheric and oceanic processes. The fifth chapter describes the application of wavelet methods in various branches of engineering, including machining, materials, dynamics and information engineering. Unlike previous chapters, this (and subsequent) chapters are styled more as literature reviews that describe the findings of other authors. The areas addressed in this chapter include: the monitoring of machining processes, the monitoring of rotating machinery, dynamical systems, chaotic systems, non-destructive testing, surface characterization and data compression. The sixth chapter continues in this vein with the attention now turned to wavelets in the analysis of medical signals. Most of the chapter is devoted to the analysis of one-dimensional signals (electrocardiogram, neural waveforms, acoustic signals etc.), although there is a small section on the analysis of two-dimensional medical images. The seventh and final chapter of the book focuses on the application of wavelets in three seemingly unrelated application areas: fractals, finance and geophysics. The treatment on wavelet methods in fractals focuses on stochastic fractals with a short section on multifractals. The treatment on finance touches on the use of wavelets by other authors in studying stock prices, commodity behaviour, market dynamics and foreign exchange rates. The treatment on geophysics covers what was omitted from the fourth chapter, namely, seismology, well logging, topographic feature analysis and the analysis of climatic data. The text concludes with an assortment of other application areas which could only be mentioned in passing. Unlike most other publications in the subject, this book does not treat wavelet transforms in a mathematically rigorous manner but rather aims to explain the mechanics of the wavelet transform in a way that is easy to understand. Consequently, it serves as an excellent overview of the subject rather than as a reference text. Keeping the mathematics to a minimum and omitting cumbersome and detailed proofs from the text, the book is best-suited to those who are new to wavelets or who want an intuitive understanding of the subject. Such an audience may include graduate students in engineering and professionals and researchers in engineering and the applied sciences.

Modeling non-harmonic behavior of materials from experimental inelastic neutron scattering and thermal expansion measurements

NASA Astrophysics Data System (ADS)

Bansal, Dipanshu; Aref, Amjad; Dargush, Gary; Delaire, Olivier

2016-09-01

Based on thermodynamic principles, we derive expressions quantifying the non-harmonic vibrational behavior of materials, which are rigorous yet easily evaluated from experimentally available data for the thermal expansion coefficient and the phonon density of states. These experimentally-derived quantities are valuable to benchmark first-principles theoretical predictions of harmonic and non-harmonic thermal behaviors using perturbation theory, ab initio molecular-dynamics, or Monte-Carlo simulations. We illustrate this analysis by computing the harmonic, dilational, and anharmonic contributions to the entropy, internal energy, and free energy of elemental aluminum and the ordered compound \\text{FeSi} over a wide range of temperature. Results agree well with previous data in the literature and provide an efficient approach to estimate anharmonic effects in materials.

Robust numerical electromagnetic eigenfunction expansion algorithms

NASA Astrophysics Data System (ADS)

Sainath, Kamalesh

This thesis summarizes developments in rigorous, full-wave, numerical spectral-domain (integral plane wave eigenfunction expansion [PWE]) evaluation algorithms concerning time-harmonic electromagnetic (EM) fields radiated by generally-oriented and positioned sources within planar and tilted-planar layered media exhibiting general anisotropy, thickness, layer number, and loss characteristics. The work is motivated by the need to accurately and rapidly model EM fields radiated by subsurface geophysical exploration sensors probing layered, conductive media, where complex geophysical and man-made processes can lead to micro-laminate and micro-fractured geophysical formations exhibiting, at the lower (sub-2MHz) frequencies typically employed for deep EM wave penetration through conductive geophysical media, bulk-scale anisotropic (i.e., directional) electrical conductivity characteristics. When the planar-layered approximation (layers of piecewise-constant material variation and transversely-infinite spatial extent) is locally, near the sensor region, considered valid, numerical spectral-domain algorithms are suitable due to their strong low-frequency stability characteristic, and ability to numerically predict time-harmonic EM field propagation in media with response characterized by arbitrarily lossy and (diagonalizable) dense, anisotropic tensors. If certain practical limitations are addressed, PWE can robustly model sensors with general position and orientation that probe generally numerous, anisotropic, lossy, and thick layers. The main thesis contributions, leading to a sensor and geophysical environment-robust numerical modeling algorithm, are as follows: (1) Simple, rapid estimator of the region (within the complex plane) containing poles, branch points, and branch cuts (critical points) (Chapter 2), (2) Sensor and material-adaptive azimuthal coordinate rotation, integration contour deformation, integration domain sub-region partition and sub-region-dependent integration order (Chapter 3), (3) Integration partition-extrapolation-based (Chapter 3) and Gauss-Laguerre Quadrature (GLQ)-based (Chapter 4) evaluations of the deformed, semi-infinite-length integration contour tails, (4) Robust in-situ-based (i.e., at the spectral-domain integrand level) direct/homogeneous-medium field contribution subtraction and analytical curbing of the source current spatial spectrum function's ill behavior (Chapter 5), and (5) Analytical re-casting of the direct-field expressions when the source is embedded within a NBAM, short for non-birefringent anisotropic medium (Chapter 6). The benefits of these contributions are, respectively, (1) Avoiding computationally intensive critical-point location and tracking (computation time savings), (2) Sensor and material-robust curbing of the integrand's oscillatory and slow decay behavior, as well as preventing undesirable critical-point migration within the complex plane (computation speed, precision, and instability-avoidance benefits), (3) sensor and material-robust reduction (or, for GLQ, elimination) of integral truncation error, (4) robustly stable modeling of scattered fields and/or fields radiated from current sources modeled as spatially distributed (10 to 1000-fold compute-speed acceleration also realized for distributed-source computations), and (5) numerically stable modeling of fields radiated from sources within NBAM layers. Having addressed these limitations, are PWE algorithms applicable to modeling EM waves in tilted planar-layered geometries too? This question is explored in Chapter 7 using a Transformation Optics-based approach, allowing one to model wave propagation through layered media that (in the sensor's vicinity) possess tilted planar interfaces. The technique leads to spurious wave scattering however, whose induced computation accuracy degradation requires analysis. Mathematical exhibition, and exhaustive simulation-based study and analysis of the limitations of, this novel tilted-layer modeling formulation is Chapter 7's main contribution.

[Book review] Seabirds of Hawaii: Natural history and conservation

USGS Publications Warehouse

Clapp, Roger B.

1991-01-01

This volume is a rather odd contribution, a hybrid between an academic work and a popular book, and both suffers and benefits from these attributes. The 18 chapters are divided into four parts that deal with the environment and humans (3 chapters and ca. 12% of the text), comparative biology of Hawaiian seabirds (5 chapters, 26%), treatments of Hawaiian seabird groups by family (7 chapters, 34%), and conservation (3 chapters, 16%). At the end of the book are an appendix of common and scientific names for plants, birds, mammals, fish, and a few invertebrates; a 6-page "selected" bibliography with pertinent references for each chapter; and an index.

The development and validation of scientific alternatives to animal testing is important not only from an ethical perspective (implementation of 3Rs), but also to improve safety assessment decision making with the use of mechanistic information of higher relevance to humans. To be effective in these efforts, it is however imperative that validation centres, industry, regulatory bodies, academia and other interested parties ensure a strong international cooperation, cross-sector collaboration and intense communication in the design, execution, and peer review of validation studies. Such an approach is critical to achieve harmonized and more transparent approaches to method validation, peer-review and recommendation, which will ultimately expedite the international acceptance of valid alternative methods or strategies by regulatory authorities and their implementation and use by stakeholders. It also allows achieving greater efficiency and effectiveness by avoiding duplication of effort and leveraging limited resources. In view of achieving these goals, the International Cooperation on Alternative Test Methods (ICATM) was established in 2009 by validation centres from Europe, USA, Canada and Japan. ICATM was later joined by Korea in 2011 and currently also counts with Brazil and China as observers. This chapter describes the existing differences across world regions and major efforts carried out for achieving consistent international cooperation and harmonization in the validation and adoption of alternative approaches to animal testing.

Spherical Tensor Calculus for Local Adaptive Filtering

NASA Astrophysics Data System (ADS)

Reisert, Marco; Burkhardt, Hans

In 3D image processing tensors play an important role. While rank-1 and rank-2 tensors are well understood and commonly used, higher rank tensors are rare. This is probably due to their cumbersome rotation behavior which prevents a computationally efficient use. In this chapter we want to introduce the notion of a spherical tensor which is based on the irreducible representations of the 3D rotation group. In fact, any ordinary cartesian tensor can be decomposed into a sum of spherical tensors, while each spherical tensor has a quite simple rotation behavior. We introduce so called tensorial harmonics that provide an orthogonal basis for spherical tensor fields of any rank. It is just a generalization of the well known spherical harmonics. Additionally we propose a spherical derivative which connects spherical tensor fields of different degree by differentiation. Based on the proposed theory we present two applications. We propose an efficient algorithm for dense tensor voting in 3D, which makes use of tensorial harmonics decomposition of the tensor-valued voting field. In this way it is possible to perform tensor voting by linear-combinations of convolutions in an efficient way. Secondly, we propose an anisotropic smoothing filter that uses a local shape and orientation adaptive filter kernel which can be computed efficiently by the use spherical derivatives.

BOOK REVIEW: Kinetic theory of plasma waves, homogeneous plasmas

NASA Astrophysics Data System (ADS)

Porkolab, Miklos

1998-11-01

The linear theory of plasma waves in homogeneous plasma is arguably the most mature and best understood branch of plasma physics. Given the recently revised version of Stix's excellent Waves in Plasmas (1992), one might ask whether another book on this subject is necessary only a few years later. The answer lies in the scope of this volume; it is somewhat more detailed in certain topics than, and complementary in many fusion research relevant areas to, Stix's book. (I am restricting these comments to the homogeneous plasma theory only, since the author promises a second volume on wave propagation in inhomogeneous plasmas.) This book is also much more of a theorist's approach to waves in plasmas, with the aim of developing the subject within the logical framework of kinetic theory. This may indeed be pleasing to the expert and to the specialist, but may be too difficult to the graduate student as an `introduction' to the subject (which the author explicitly states in the Preface). On the other hand, it may be entirely appropriate for a second course on plasma waves, after the student has mastered fluid theory and an introductory kinetic treatment of waves in a hot magnetized `Vlasov' plasma. For teaching purposes, my personal preference is to review the cold plasma wave treatment using the unified Stix formalism and notation (which the author wisely adopts in the present book, but only in Chapter 5). Such an approach allows one to deal with CMA diagrams early on, as well as to provide a framework to discuss electromagnetic wave propagation and accessibility in inhomogeneous plasmas (for which the cold plasma wave treatment is perfectly adequate). Such an approach does lack some of the rigour, however, that the author achieves with the present approach. As the author correctly shows, the fluid theory treatment of waves follows logically from kinetic theory in the cold plasma limit. I only question the pedagogical value of this approach. Otherwise, I welcome this addition to the literature, for it gives the teacher of the subject a valuable reference where the inquisitive student will be able to read up on and satisfy himself about the practicality and reliability of the Vlasov theory in a hot magnetized and collisionless plasma. The book has excellent treatments of several new topics not included in previous textbooks, for example, the relativistic theory of plasma wave propagation, so important in electron cyclotron heating of magnetically confined fusion plasmas, a discussion of current drive theory and there is a welcome introduction to parametric instabilities in the final chapter. There are some things that make the readability of the book somewhat difficult. In the early parts, certain advanced concepts are introduced without much motivation or explanation, although the author is trying to be helpful by providing a list of relevant references at the end of each chapter. Here the teacher's role will be critical. Again, a certain amount of previous knowledge of the subject would prove to be invaluable to the student. The main content of the book is included in 11 chapters. Use is made of CGS Gaussian units, a favourite of plasma theorists. As the author states, these are still widely used in advanced plasma theory, and the student is well advised to become familiar with this system of units (as well as the SI system for applications). To help the reader in the Introduction, the author defines various expressions often used in plasma physics in practical units (frequencies in hertz, lengths in centimetres, temperatures in kiloelectronvolts and magnetic fields in teslas). Chapter 2 is entitled `Plasma Electrodynamics' and it introduces the Maxwell-Vlasov set of equations, as well as the important fundamentals of wave propagation, such as polarization, dispersion and the dielectric tensor, and energy relations. In Chapter 3, `Elementary Plasma Kinetic Theory', the author derives the Vlasov equation and the Fokker-Planck equation from the BBGKY hierarchy. This is a somewhat unusual chapter in a book on plasma waves, but I welcome it since it demonstrates the author's desire to be complete and rigorous in justifying the use of the collisionless Vlasov equation for `high frequency' wave propagation phenomena. Incidentally, it is interesting that while the author derives the Fokker-Planck equation at great length, it is used only to derive the fluid and MHD equations, but not for estimating Coulomb collisional damping of specific waves in later chapters. Chapter 4 gives the derivation of the hot plasma dielectric tensor. There is an extensive and excellent discussion of the relativistic formulation of the dielectric tensor, which is of fundamental importance to practising fusion physicists (for example) involved in ECR heating of high temperature plasmas. Various temperature limits are taken in Chapters 5, 6 and 7, and the author discusses the infinite number of waves in the cold plasma limit (Chapter 5), in the hot plasma limit (Chapter 6) and in the electrostatic limit (Chapter 7). In my opinion, these chapters represent the `meat' of the book. Chapter 7 includes a detailed treatment of electrostatic waves in a hot plasma, including Bernstein waves and their damping at high harmonics. This is a difficult topic, and the extensive treatment presented here is hard to find in other texts. The author also includes a discussion of two stream instabilities here, together with the Nyquist-Penrose criterion for instability. Chapter 8 discusses linear wave-particle interactions, including damping of electromagnetic waves, RF current drive and RF heating. Chapter 9 is called `Collisionless Stochasticity' and institutes an introduction to the subject as well as applications to the heating of ions by high harmonic, lower hybrid waves. Chapter 10 is another key part of the book, on the quasilinear theory of heating and current drive. It deals with the practical aspects of RF heating and current drive in magnetically confined fusion plasmas, and is a `must read' for researchers dealing with RF heating and related transport. Chapter 11 attempts to deal with non-linear effects in the presence of high power RF waves in plasmas. First, the author deals with the difficult subject of mode coupling theory, but, owing to its complexity, the formulation is never reduced to practical applications. Only the `dipole approximation' section can be used to make practical estimates of non-linear effects during RF heating. There are some shortcomings of this book that need to be mentioned here. There are some typographical errors, including spelling errors. The labelling on the figures is often hard to read due to their poor quality and small size. The figures themselves are often too small and are overloaded with curves (e.g., Figs 18.1, 18.2, 21.3, 28.13). The author must have spent a significant effort in producing these curves, and they deserve a better presentation, especially if they are to be used by students. Ease of readability is important for a textbook intended for students and researchers alike. It is hoped that such shortcomings will be improved in future editions, as well as in Volume II, which is to follow. To summarize, this book presents an up to date major contribution to the field of plasma waves and is a `must' on the shelves of active researchers as well as advanced graduate students. Under the guidance of a knowledgeable teacher, the book may be used as a text, with appropriate omissions of certain sections for a one semester course in plasma waves. Alternatively for those who have mastered the fundamentals of wave propagation in plasmas, the book could be used as a basis for an advanced seminar course. I am looking forward with anticipation to Volume II, Waves in Inhomogeneous Plasmas, by Marco Brambilla, one of the eminent plasma wave theorists of our generation.

2010-01-26

...We are amending the phytosanitary treatment regulations in 7 CFR part 305 by removing the lists of approved treatments and treatment schedules from the regulations, while retaining the general requirements for performing treatments and certifying or approving treatment facilities. We are removing treatment schedules from other places where they are currently found in 7 CFR chapter III as well. Approved treatment schedules will instead be found in the Plant Protection and Quarantine Treatment Manual, which is available on the Internet. We are also establishing a new process to provide the public with notice and the opportunity to comment on changes to treatment schedules. Finally, we are harmonizing and combining the requirements for performing irradiation treatment for imported articles, articles moved interstate from Hawaii and U.S. territories, and articles moved interstate from an area quarantined for fruit flies. These changes will simplify and expedite our processes for adding, changing, and removing treatment schedules while continuing to provide for public participation in the process. These changes will also simplify our presentation of treatments to the public by consolidating all treatments into one document and eliminating redundant text from the regulations.

This chapter addresses both the development and substance of the World Anti-Doping Code, which came into effect in 2003, as well as the subsequent Code amendments, which came into effect in 2009 and 2015. Through an extensive process of stakeholder input and collaboration, the World Anti-Doping Code has transformed the hodgepodge of inconsistent and competing pre-2003 anti-doping rules into a harmonized and effective approach to anti-doping. The Code, as amended, is now widely recognized worldwide as the gold standard in anti-doping. The World Anti-Doping Code originally went into effect on January 1, 2004. The first amendments to the Code went into effect on January 1, 2009, and the second amendments on January 1, 2015. The Code and the related international standards are the product of a long and collaborative process designed to make the fight against doping more effective through the adoption and implementation of worldwide harmonized rules and best practices. © 2017 S.

The Evolution of Surface Symmetry in Femtosecond Laser-Induced Transient States of Matter

NASA Astrophysics Data System (ADS)

Garnett, Joy Carleen

Gallium arsenide and other III-V materials are well known for their excellent optical and electronic properties and have led to the development of high-performance photovoltaic cells1,2, photoelectrochemical water splitting3,4, and light emitting diodes (LEDs)5. Several combinations of III-V semiconductors are now being considered as potentially attractive alternatives to silicon for these applications. However, further development requires fundamental understanding of processes that govern light-matter interactions. Specifically, surface strain and ultrafast dynamics are of great interest to the optoelectronic industry. Strained semiconductor surfaces dominate the design of optoelectronics and III-V semiconductor-based LEDs. Currently, the structures of strained surfaces are well characterized with x-ray diffraction (XRD)6 and electron crystallography7-9. However, optically-induced electronic behavior at these interfaces are not fully understood. This has the been one of the stimulants for the research in this dissertation. To further explore opticallyinduced electronic behavior at strained interfaces, I have asked the following questions: 1. How does static optoelectronic behavior change as a function of strain? 2. How does surface symmetry and electronic motion change with respect to strain? 3. How do atomic bonds change as a function of strain? Another main research goal of this work is to understand ultrafast subpicosecond processes after pulsed laser excitation. The knowledge of ultrafast processes dominates the design of devices in industries that require high temporal and spectral resolution. Ultrafast atomic motion has been the major focus of subpicosecond structural dynamics. Currently, these dynamics upon photoexcitation are well characterized with experimental methods such as ultrafast x-ray diffraction (U-XRD), ultrafast electron diffraction (UED), and ultrafast electron crystallography (UEC). However, ultrafast atomic motion does not occur alone. The bonds connecting these moving atoms are also affected during this process. The correlation between structural and electronic dynamics is not well understood. To further explore correlated structural and electronic behavior upon ultrafast laser excitation, I have asked the following questions: 1. How does subpicosecond optoelectronic behavior change as a function of time after femtosecond pulse photoexcitation? 2. How does subpicosecond surface symmetry and electronic motion change with respect to time after femtosecond pulse photoexcitation? 3. How do atomic bonds change as a function of time after femtosecond pulse photoexcitation? To address these questions, I used experimental methods sensitive to both atomic motions and electronic responses: polarization-resolved second harmonic generation (PRSHG) and timeresolved, polarization-resolved second harmonic generation (TRPRSHG). The dissertation covers application of these techniques to III-V semiconductors: gallium arsenide (GaAs), gallium antimonide (GaSb), and aluminum gallium arsenide (AlGaAs). This dissertation is organized as follows. Chapter 2 presents the background of electronic band structures, ultrafast relaxation processes, and the origin of nonlinear optics from the perspectives of classical and quantum mechanics. It thus provides a framework for the static and transient nonlinear optical processes observed in III-V semiconductors under ultrafast pulse excitation. Next, Chapter 3 motivates the use of the experimental and analytical methods as applied to the experimental and theoretical studies outlined in Chapters 4 and 5. Chapter 4 is devoted to the understanding of polarization-resolved second-order nonlinear optical responses of various strained III-V semiconductor heterostructures resulting from defect-conducive growth conditions. Simplified phenomenological expressions for the polarization-resolved second harmonic generation (PRSHG) are first derived using tensor analysis. Afterwards, these expressions are used to fit experimental data. The developed formalism is tested under different conditions to gauge the fit robustness and sensitivity to mechanical and electronic changes in strained IIIV semiconductors. Along that same vein, Chapter 5 extends this analytical fit to describe ultrafast PRSHG responses of GaAs (100) as a function of transient changes in the interatomic potential within the first picosecond after photoexcitation. Finally, the dissertation concludes with Chapter 6 addressing possible directions for future work. The chapter begins with a description of studies to further test the sensitivity and robustness of the PRSHG phenomenological fit and how it can be used to characterize more classes of materials.

Environmental Chemical Analysis (by B. B. Kebbekus and S. Mitra)

NASA Astrophysics Data System (ADS)

Bower, Reviewed By Nathan W.

1999-11-01

This text helps to fill a void in the market, as there are relatively few undergraduate instrumental analysis texts designed specifically for the expanding population of environmental science students. R. N. Reeve's introductory, open-learning Environmental Analysis (Wiley, 1994) is one of the few, and it is aimed at a lower level and is less appropriate for traditional classroom study. Kebbekus and Mitra's book appears to be an update of I. Marr and M. Cresser's excellent 1983 text by the same name (and also published under the Chapman and Hall imprint). It assumes no background in instrumental methods of analysis but it does depend upon a good general chemistry background in kinetic and equilibrium calculations and the standard laboratory techniques found in a classical introduction to analytical chemistry. The slant taken by the authors is aimed more toward engineers, not only in the choice of topics, but also in how they are presented. For example, the statistical significance tests presented follow an engineering format rather than the standard used in analytical chemistry. This approach does not detract from the book's clarity. The writing style is concise and the book is generally well written. The earlier text, which has become somewhat of a classic, took the unusual step of teaching the instruments in the context of their environmental application. It was divided into sections on the "atmosphere", the "hydrosphere", the "lithosphere", and the "biosphere". This text takes a similar approach in the second half, with chapters on methods for air, water, and solid samples. Users who intend to use the book as a text instead of a reference will appreciate the addition of chapters in the first half of the book on spectroscopic, chromatographic, and mass spectrometric methods. The six chapters in these two parts of the book along with four chapters scattered throughout on environmental measurements, sampling, sample preparation, and quality assurance make a nice package overall, although I might personally prefer a chapter on environmental chemometrics as well. Most of the major instrumental methods actively employed in environmental analysis are treated either in the theoretical chapters or in the later application chapters. These include introductions to UV­vis, FTIR, SFC, HPLC, IC (but not CE), GC, GC­MS, ISEs, anodic stripping, FAA, GFAA, XRF, ICP, ICP­MS, and even two pages on the basics of immunoassays. Although this text provides an update of the earlier book, its greatest failing is a particular strength of the first text: it fails to provide any detailed references within the text, relying on an average of five generic "suggested readings" at the end of each chapter. Even tables such as "Some US drinking water quality standards" give no references, setting a bad example for students who have to write research papers of their own. As it also does not provide the detailed procedures or fine-quality figures that were available in the earlier text, it is not worth as much as a reference book or for library acquisitions. In the first book the detailed procedures served as a "lab manual within the text" and this increased its pedagogic value tremendously. Still, this text does make use of generalized procedures to step through many of the standard methods encountered by practicing environmental scientists, and the tables are in most cases superior to those in similar texts, lacking only the references to make them as useful as they might be. A second weakness of note comes from the organization. Having two different parts of the book covering material that relates to each of the instrumental methods means that it is not always clear where the reader should go to find information that relates to a particular method. For example, specifics on sampling equipment for water and soils appear in the chapter on sampling, but for air they appear in the applications section. Similarly, the sample preparation chapter would make more logical sense if it appeared before the instrumental methods that make use of it, and the F-test should be discussed before it is called upon to tell whether two populations have the same variance. The various discussions rarely refer the reader to related material located in other parts of the text, so occasionally one is left wondering about the lack of coverage. However, in the end the authors do introduce all the topics fairly well, and the text seems to have a good index. In summary, this text provides a very readable introduction to instrumental environmental analysis that is appropriate for a one-semester course designed for advanced undergraduate environmental engineering and environmental science students. If the instructor is careful to read the text beforehand so as to guide the students appropriately, supplying additional references when experimental work is to be undertaken, it should also work satisfactorily in courses that have a laboratory component.

Chapter 11.2: Inverters, Power Optimizers, and Microinverters

DOE Office of Scientific and Technical Information (OSTI.GOV)

Deline, Christopher A

Inverters span a wide range of sizes, topologies, and connection voltages: from utility-scale megawatt inverters to string inverters. Switch-mode power conversion relies on high frequency chopping of DC signal to periodically charge and discharge energy storage elements, such as inductors and capacitors. Additional circuit components are required to address practical issues in inverters such as voltage ripple and harmonic distortion. Inverters are beginning to incorporate components with a bandgap above should be 3 eV, such as SiC and GaN. Photovoltaic (PV) modules respond dynamically to changing temperature and irradiation conditions. Thus, maximum DC power extraction requires periodic adjustment of themore » PV voltage and current operating point. An inverter's total efficiency is measured by the product of its conversion efficiency and the maximum-power-point tracking (MPPT) efficiency. This chapter lists the primary functions of inverters that include auxiliary capabilities, such as monitoring of DC and AC performance, and other error reporting.« less

Adaptive cellular structures and devices with internal features for enhanced structural performance

NASA Astrophysics Data System (ADS)

Pontecorvo, Michael Eugene

This dissertation aims to develop a family of cellular and repeatable devices that exhibit a variety of force-displacement behaviors. It is envisioned that these cellular structures might be used either as stand-alone elements, or combined and repeated to create multiple types of structures (i.e. buildings, ship hulls, vehicle subfloors, etc.) with the ability to passively or actively perform multiple functions (harmonic energy dissipation, impact mitigation, modulus change) over a range of loading types, amplitudes, and frequencies. To accomplish this goal, this work combines repeatable structural frameworks, such as that provided by a hexagonal cellular structure, with internal structural elements such as springs, viscous dampers, buckling plates, bi-stable von Mises trusses (VMTs), and pneumatic artificial muscles (PAMs). The repeatable framework serves to position damping and load carrying elements throughout the structure, and the configuration of the internal elements allow each cell to be tuned to exhibit a desired force-displacement response. Therefore, gradient structures or structures with variable load paths can be created for an optimal global response to a range of loads. This dissertation focuses on the development of cellular structures for three functions: combined load-carrying capability with harmonic energy dissipation, impact mitigation, and cell modulus variation. One or more conceptual designs are presented for devices that can perform each of these functions, and both experimental measurements and simulations are used to gain a fundamental understanding of each device. Chapter 2 begins with a presentation of a VMT model that is the basis for many of the elements. The equations of motion for the VMT are derived and the static and dynamic behavior of the VMT are discussed in detail. Next, two metrics for the energy dissipation of the VMT - hysteresis loop area and loss factor - are presented. The responses of the VMT to harmonic displacement and force inputs are contrasted in relation to these metrics. The key innovation to the early structural elements presented here is the combination of the VMT with the pin-jointed hexagonal cell. Chapter 3 explores several prototypes of repeatable structural elements for simultaneous load-carrying capability and energy dissipation that are based on this innovation. The final demonstration prototype presented in this chapter is a column-like element that is based on a hexagonal cell containing two horizontal springs and one vertical damper. The unit is enclosed by a pair of buckling plates that serve to give the prototype a high initial stiffness and load carrying capability. The prototype is tested in both displacement and force input and its behavior is compared to simulation. Chapter 4 builds on the conceptual designs of Chapter 3 with the introduction of a plate-like element, that contains two compact VMTs connected by a horizontally oriented damper. Pre-loaded springs are used in the prototype to perform the same load carrying function as the buckling plates in the column-like prototype with increased predictability. The plate-like prototype is studied under impact to demonstrate its effectiveness as a protective layer. It is shown to reduce peak impact loads transmitted to the base of the device by over 60%. In most cases, the prototype compares well with a conventional protective rubber layer, and in cases of extreme impact loads, it exceeds the performance of the rubber layer. In addition to impact testing, the prototype is also experimentally tested under harmonic displacement input, and is simulated under both harmonic displacement and force input. The experiments illustrate that while the VMT parameters of a single layer can be optimized to a particular harmonic load amplitude, having two layers with softer and stiffer VMTs allows the system to show good energy dissipation characteristics at different harmonic load amplitude levels. Chapter 5 examines using PAM inclusions within planar hexagonal cells as variable stiffness springs to create a variable modulus cellular structure. The proposed concept is envisioned as a first step toward a structural unit cell whose in-plane modulus in a given direction can be tuned based on the orientation of PAMs within the cell and the pressure supplied to the individual muscles. To begin, a pin-jointed cell is considered, loaded in the horizontal direction, with three PAMs (one vertical PAM and two horizontal PAMs) oriented in an "H" configuration between the vertices of the cell. A method for calculation of the hexagonal cell modulus is introduced, as is an expression for the balance of tensile forces between the horizontal and vertical PAMs. An aluminum hexagonal unit cell is fabricated and simulation of the hexagonal cell with PAM inclusions is then compared to experimental measurement of the unit cell modulus in the horizontal direction over a pressure range up to 682 kPa. An increase in cell modulus of 200% and a corresponding change in cell angle of 1.53 degrees are demonstrated experimentally. A design study via simulation predicts that differential pressurization of the PAMs up to 1992 kPa can increase the cell modulus in the horizontal direction by a factor of 6.66 with a change in cell angle of only 2.75 degrees. Additionally, simulation predicts that variation of unpressurized cell equilibrium angle and vertical wall length coefficient can result in changes in cell modulus greater than 1000%. A drawback of the pin-jointed cell with PAM inclusions is that it is inherently underconstrained. To solve this problem, the pin-jointed cell walls are replaced with a continuous Delrin hexagon which gives the cell kinematic stability and allows for experimental measurement of modulus in both the horizontal and vertical directions. The Delrin cell is designed to have a modulus on the same order as that of the pin-jointed cell at zero pressure and is experimentally measured without the PAM inclusions. These measurements validate the use of a combined flexural/hinging analytical model that accurately simulates the cell modulus. This analysis is then combined with the PAM force equations to model the complete hexagonal cell with PAM inclusions. Simulation and experimental measurement of the cell modulus with the PAM inclusions are compared in both the horizontal and vertical directions over an expanded pressure range up to 1302 kPa. The interplay between the contraction ratio and pressure in orthogonal sets of PAMs is highlighted as the primary driver of overall cell modulus.

Chapter 23: International Standard reagents for harmonization of HPV serology and DNA assays--an update.

International reference materials such as International Standard reagents facilitate quality assurance of essential biopharmaceutical products and related in vitro diagnostic tests. Standardization of antibody and DNA measurements and harmonization of laboratory procedures are key to the success of cancer prevention strategies through screening methods as well as for development and implementation of vaccination against the human papillomavirus (HPV). The WHO supported the preparation and initial analysis of a panel of candidate serological and DNA reference reagents aimed at facilitating inter-laboratory comparisons and detection of HPV worldwide. Two international collaborative studies assessed the performance of various HPV antibody and HPV-DNA detection assays and examined the feasibility of generating HPV antibody and DNA standard reagents. These studies showed that improvement in performance and comparability of assays is urgently needed and that the use of the same International Standard reference reagent could significantly improve performance and comparability. It is hoped that the establishment of International Units and International Standards for HPV antibody and DNA analysis will be pursued with high priority.

Official USP Reference Standards: metrology concepts, overview, and scientific issues and opportunities.

PubMed

Williams, Roger L

2006-01-23

The United States Pharmacopeia (USP) is a private standards-setting body created in 1820 by practitioners who wished to promote the quality of therapeutic products in commerce. The principal product of USP, then and now, is the United StatesPharmacopeia (USP), to which was added the National Formulary (NF) in 1975. The two compendia are published as a combined text annually (USP-NF). Originally a book of process standards, USP-NF evolved over time into compendia containing primarily product standards that are expressed in monographs for therapeutic ingredients, products, and excipients. As a public health service, USP supplies official USP Reference Standards to manufacturers and others who wish to test an article according to selected procedures of a monograph or General Chapter. During the past decade, understanding of USP monographs and official USP Reference Standards as a means of controlling the quality of a therapeutic article has evolved, based on advances in metrology, on activities in the International Conference on Harmonization of Technical Requirements for the Registration of Pharmaceuticals for Human Use (ICH), and on considerations by the USP Council of Experts and its Expert Committees and USP staff. This article discusses the evolution of this understanding, focusing on drug substances and excipients for well-characterized small molecules and their corresponding dosage forms.

Whissell, C M

1997-02-01

Random samples taken from six recent textbooks and three older books in introductory psychology were analyzed with respect to linguistic style, emotional tone, and pattern of citation. Newer and older books, individual books, and categories of chapters within books were compared to each other. Analysis suggests that newer books are longer and linguistically more complicated. They also contain proportionally more citations, and more text pages devoted to social psychology and psychopathology than older books. There were several significant stylistic and emotional differences among books and some significant content differences among chapters.

Biochemistry (by Jochanan Stenesh)

NASA Astrophysics Data System (ADS)

Glasfeld, Arthur

1999-06-01

Plenum: New York, 1998. Hardcover, ISBN 0 306-45732-6. 95. Paperback, ISBN 0 306 45733 4. 55 (set of 3). Solutions manual and transparencies available. According to the promotional materials accompanying this text, its intended audience is students in one-semester undergraduate biochemistry courses. At just over 500 pages, the book is shorter than the norm of well over 1000 pages. The challenge, then, is to present the subject in a coherent and compelling fashion while necessarily omitting a large fraction of the material that one normally finds in more inclusive texts. That kind of editing is obviously going to lead to squawking from some quarters, so I should put my prejudices on the table. I teach a one-semester course in biochemical structure, and I have a long-standing interest in using molecular models to explain biochemical behavior, both in research and in teaching. The editing performed by Professor Stenesh is likely to trouble someone with a structural or mechanistic background. Rather than selectively excluding some topics, Stenesh has created a table of contents that looks like it's from a much longer text. The usual chapters on biochemical structure, catalysis, metabolism and molecular genetics are included here. The ax fell elsewhere, and most obvious to my eye are the omissions of structure and chemical mechanism beyond those few chapters that are dedicated to them. A brief presentation on the structure and function of hemoglobin is given in the chapter on proteins, and the catalytic mechanism of chymotrypsin is briefly presented in the chapter on catalysis. But in chapters on metabolism, the structures of substrates and products are shown while mechanisms of conversion are omitted. For example, in the description of aldolase, we're informed that the enzyme catalyzes a reverse aldol condensation, but the reader isn't shown how the aldol condensation relates to the chemical conversion we see in the figure. (Part of the problem may be that the text assumes only one semester of preparation in organic chemistry, which might not be adequate for a discussion of biochemical mechanism.) In the section on gene regulation, no mention is made of the atomic-level interactions between regulatory proteins and DNA that lead to specific, high-affinity binding. The helix-turn-helix motif isn't even mentioned. Obviously, in a 500-page text, something had to go. It's too bad, though, that the omitted material includes the structural and mechanistic explanations for the chemical transformations and cellular processes being described. These complaints shouldn't overshadow the fact that this is a thoughtfully constructed text. The writing is both clear and simple. Broken into subsections, topics are presented in brief synopses that carefully identify key terms and ideas, and the problems at the back of the chapters are plentiful and appropriate. Stenesh's presentation is logically sound. I appreciated the presentation of thermodynamics in a chapter that directly precedes metabolism, rather than the more common brief review that appears in the earliest chapters. Likewise, the inclusion of enzyme catalysis directly after protein structure works in the context of this text. I noted a few small errors, but nothing that would cause distractions for the student. Unfortunately, the two-color graphics that accompany the text are less than compelling by current standards (also, a relatively greater number of errors appear in the figures). In drawing chemical structures, little effort is made to show molecular shape. For example, the figures use Fischer projections (without definition before Chapter 5) to define stereoisomers, and only in the appendix are dashes and wedges used to define them. This is particularly problematic in the chapter on amino acids, where their chirality is described but never illustrated. It is difficult to see the three-dimensional concepts being presented in the two-dimensional format being used. In topics where good visuals would be most useful (such as protein and DNA structure), the figures are reminiscent of those from textbooks of the 1970s. For my tastes, this text takes an overly conservative approach to biochemistry. The subject, which has expanded rapidly in the past few decades, can be presented in a format that reflects those changes. My preference would be for a more restricted selection of topics presented with greater emphasis on how mechanism and structure play a role in our understanding in those areas. However, for those who are looking for a no-frills approach to teaching a single-semester course in biochemistry, Stenesh's text may be a welcome option. It puts all the basic material of biochemistry on the table, and in departments that offer advanced courses, this could be enough for the first semester. In one of the testimonials in the promotional literature that accompanied the book, the text is described as "clearly written, intelligently organized and devoid of extraneous, distracting 'glitz'." It appears that one person's "substance" can be another's "glitz". Consider adopting this text accordingly.

Examining End-Of-Chapter Problems Across Editions of an Introductory Calculus-Based Physics Textbook

NASA Astrophysics Data System (ADS)

Xiao, Bin

End-Of-Chapter (EOC) problems have been part of many physics education studies. Typically, only problems "localized" as relevant to a single chapter were used. This work examines how well this type of problem represents all EOC problems and whether EOC problems found in leading textbooks have changed over the past several decades. To investigate whether EOC problems have connections between chapters, I solved all problems of the E&M; chapters of the most recent edition of a popular introductory level calculus-based textbook and coded the equations used to solve each problem. These results were compared to the first edition of the same text. Also, several relevant problem features were coded for those problems and results were compared for sample chapters across all editions. My findings include two parts. The result of equation usage shows that problems in the E&M; chapters do use equations from both other E&M; chapters and non-E&M; chapters. This out-of-chapter usage increased from the first edition to the last edition. Information about the knowledge structure of E&M; chapters was also revealed. The results of the problem feature study show that most EOC problems have common features but there was an increase of diversity in some of the problem features across editions.

Theory, Design and Operation of a High-Power Second - Gyro-Twt Amplifier.

NASA Astrophysics Data System (ADS)

Wang, Qinsong

1995-01-01

Based on the cyclotron resonance maser (CRM) instability, the gyrotron traveling wave tube (gyro-TWT) amplifier is an efficient high power microwave and millimeter wave coherent radiation source. As evidenced in previous experiments, gyro-TWTs, however, can be very susceptible to spontaneous oscillations, and their output powers have thus been limited to relatively low levels. In this dissertation work, thorough theoretical and experimental studies have been conducted to demonstrate and confirm a novel "marginal stability design" (MSD) concept that a harmonic gyro-TWT amplifier is more stable to spontaneous oscillation than a fundamental harmonic gyro-TWT amplifier. Since their interactions are, in general, weaker and allow higher levels of electron beam current, harmonic gyro-TWTs can yield, in principle, a significantly higher RF output power than a fundamental gyro-TWT. The study results also show that a magnetron injection gun (MIG) type electron beam is applicable to harmonic gyro-TWTs. A complete analytic linear theory employing Laplace transforms and a three dimensional nonlinear theory using a slow time-scale formalism are developed in Chapt. 2 for the general CRM interaction to address the issue of stability. Two designs were developed to demonstrate the MSD procedure. The design and development of the proof -of-principle experiment are discussed in Chapt. 3. The accompanying cold test results indicate that all the components have met their respective design goals. The RF diagnostic circuit employed to characterize the gyro-TWT amplifier is also described. Chapter 4 presents the hot-test results of the second-harmonic TE_{21} gyro-TWT amplifier experiment in which an 80 kV, 20 A MIG beam with alpha(equivupsilon _|/upsilon_|) = 1 was used to generate a peak RF output power of 207 kW in Ku-band with an efficiency of 12.9%. In addition, the saturated gain is 16 dB, the small signal gain is 22 dB, the measured bandwidth is 2.1%, and the amplifier was zero-drive stable. As pointed out in Chapt. 5, the theoretical and experimental studies conducted in this work have successfully realized their objectives. Further improvements to the current proof-of-principle experiment and an increase in the operating frequency by operating at an even higher cyclotron harmonic are promising and worthy of future efforts.

2010-01-01

In this chapter, we cover basic and fundamental principles and methods in statistics - from "What are Data and Statistics?" to "ANOVA and linear regression," which are the basis of any statistical thinking and undertaking. Readers can easily find the selected topics in most introductory statistics textbooks, but we have tried to assemble and structure them in a succinct and reader-friendly manner in a stand-alone chapter. This text has long been used in real classroom settings for both undergraduate and graduate students who do or do not major in statistical sciences. We hope that from this chapter, readers would understand the key statistical concepts and terminologies, how to design a study (experimental or observational), how to analyze the data (e.g., describe the data and/or estimate the parameter(s) and make inference), and how to interpret the results. This text would be most useful if it is used as a supplemental material, while the readers take their own statistical courses or it would serve as a great reference text associated with a manual for any statistical software as a self-teaching guide.

Voltage management of distribution networks with high penetration of distributed photovoltaic generation sources

NASA Astrophysics Data System (ADS)

Alyami, Saeed

Installation of photovoltaic (PV) units could lead to great challenges to the existing electrical systems. Issues such as voltage rise, protection coordination, islanding detection, harmonics, increased or changed short-circuit levels, etc., need to be carefully addressed before we can see a wide adoption of this environmentally friendly technology. Voltage rise or overvoltage issues are of particular importance to be addressed for deploying more PV systems to distribution networks. This dissertation proposes a comprehensive solution to deal with the voltage violations in distribution networks, from controlling PV power outputs and electricity consumption of smart appliances in real time to optimal placement of PVs at the planning stage. The dissertation is composed of three parts: the literature review, the work that has already been done and the future research tasks. An overview on renewable energy generation and its challenges are given in Chapter 1. The overall literature survey, motivation and the scope of study are also outlined in the chapter. Detailed literature reviews are given in the rest of chapters. The overvoltage and undervoltage phenomena in typical distribution networks with integration of PVs are further explained in Chapter 2. Possible approaches for voltage quality control are also discussed in this chapter, followed by the discussion on the importance of the load management for PHEVs and appliances and its benefits to electric utilities and end users. A new real power capping method is presented in Chapter 3 to prevent overvoltage by adaptively setting the power caps for PV inverters in real time. The proposed method can maintain voltage profiles below a pre-set upper limit while maximizing the PV generation and fairly distributing the real power curtailments among all the PV systems in the network. As a result, each of the PV systems in the network has equal opportunity to generate electricity and shares the responsibility of voltage regulation. The method does not require global information and can be implemented either under a centralized supervisory control scheme or in a distributed way via consensus control. Chapter 4 investigates autonomous operation schedules for three types of intelligent appliances (or residential controllable loads) without receiving external signals for cost saving and for assisting the management of possible photovoltaic generation systems installed in the same distribution network. The three types of controllable loads studied in the chapter are electric water heaters, refrigerators deicing loads, and dishwashers, respectively. Chapter 5 investigates the method to mitigate overvoltage issues at the planning stage. A probabilistic method is presented in the chapter to evaluate the overvoltage risk in a distribution network with different PV capacity sizes under different load levels. Kolmogorov--Smirnov test (K--S test) is used to identify the most proper probability distributions for solar irradiance in different months. To increase accuracy, an iterative process is used to obtain the maximum allowable injection of active power from PVs. Conclusion and discussions on future work are given in Chapter 6.

Book Reviews

NASA Astrophysics Data System (ADS)

Horner, Joseph L.

1987-04-01

Progress in the fields of integrated optics and fiber optics is continuing at a rapid pace. Recognizing this trend, the goal of the author is to provide an introductory textbook on time-harmonic electromagnetic theory, with an emphasis on optical rather than microwave technologies. The book is appropriate for an upper-level undergraduate or graduate course. Each chapter includes examples of problems. The book focuses on several areas of prime importance to intergrated optics. These include dielectric waveguide analysis, couple-mode thoery, Bragg scattering, and prism coupling There is very little coverage of active components such as electro-optic modulators and switches. The author assumes the reader has a working knowledge of vector calculus and is familiar with Maxwell's equations.

Analytical Chemistry (edited by R. Kellner, J.- M. Mermet, M. Otto, and H. M. Widmer)

NASA Astrophysics Data System (ADS)

Thompson, Reviewed By Robert Q.

2000-04-01

This text, written in English, was developed by the Division of Analytical Chemistry of the Federation of European Chemical Societies to support the university-level Eurocurriculum in analytical chemistry, a major effort of academics and other analytical scientists throughout Europe and an outgrowth of the economic unification of European countries. The goal of a uniform curriculum and text for analytical chemistry across national borders is laudable, and the editors, led by the late Robert Kellner, deserve commendation for their accomplishments. (The U.S., in contrast, has been late in considering the analytical chemistry curriculum and only recently has published a pamphlet, Curricular Developments in the Analytical Sciences, an outgrowth of several NSF-sponsored workshops.) I can't remember another analytical text that begins with mention of the "big bang" and the beginnings of the universe (!), but I don't believe that the authors and publisher are looking to export their curriculum to neighboring planets. However, I am sure that they are interested in the North American market and its strong analytical chemistry community. It is in this context and in comparison with leading analytical texts in the U.S. that I write this review. At first glance, Analytical Chemistry overwhelms. It is a large book of more than 900 pages, a mass of 2.3 kg, and a volume of nearly 3 L. It is not a book that is easy to stuff into a backpack for the trip to class or lab. Students also may resent paying top dollar for a book that might not last the semester, given that the pages of my review copy began to pull away from the binding after only a few days of gentle use. Beneath the snazzy cover there is a dearth of color printing and photographs. This, combined with a smallish font and figures that are inconsistent in size, quality, and font, makes for a book that is not especially easy on the eyes. The large margins provide ample space for the numerous figures, figure captions, and marginal notes. The text is divided into 5 parts (General Topics, Chemical Analysis, Physical Analysis, Computer-Based Analytical Chemistry, and Total Analysis Systems), 16 sections, and many chapters and subsections, all numbered and with headings for easy reference. The book provides comprehensive coverage of analytical science. Many curricula in North America cling to the tired notion of one semester of classical analytical (wet) chemistry followed by a second semester of instrumental analysis, and publishers continue to respond by publishing separate texts for each course. The Europeans, in contrast, have a text that bridges this artificial gap. Included are chapters and subsections on chemical equilibrium, electronic and vibrational spectroscopy, separations, and electrochemistry (found in most first courses in analytical chemistry). The authors also address atomic spectroscopy in all of its forms, luminescence, mass spectrometry, NMR spectrometry, surface analysis, thermal methods, activation analysis, and automated methods of analysis (found in most instrumental courses). Additional, uncommon chapters on chemical and biochemical sensors, immunoassay, chemometrics, miniaturized systems, and process analytical chemistry point toward the present and future of analytical science. The only glaring omission in comparison to other instrumental texts is in the area of measurement systems and electronics. No mention is made of the analytical laboratory, such as descriptions of glassware calibration and suggested experiments, as is found in most quantitative analysis texts in the U.S. The dangers in any multi-authored book include an uneven treatment of topics and a lack of cohesiveness and logical development of topics. I found some evidence of these problems in Analytical Chemistry. My first reaction to the Table of Contents and the grouping of chapters was "Where is ?" and "What about ?" While the order of topics in an analytical chemistry course always is open to debate (I have done my share of reshuffling over the years), some timing is sacrosanct. For example, I suspect that most first courses in analytical chemistry include basic statistics early on, yet this topic is found under Chemometrics in Part IV. Another example is the separation of the discussions of acid-base equilibria (Chapter 4) and acid-base titrations (Chapter 7), with chromatography and kinetics interspersed. Simple UV-vis spectrometry and Beer's law are discussed after topics such as thermal analysis and biosensors. Information on monochromators is buried in the chapter on atomic emission spectroscopy. The editors have organized the material in a reasonably logical yet unfamiliar order. I would guess that those who adopt this text will need to skip from chapter to chapter or restructure their courses in a major way. Some topics receive more or less attention than I believe is justified. Let me provide a few examples of this uneven treatment. The editors include in Part I a 5-page description of the regulatory aspects of QA & QC, a topic of little interest to undergraduates. In the liquid chromatography section there are 3.5 pages on thin-layer chromatography and 6.5 pages on field flow fractionation, but only 2.5 pages on capillary electrophoresis, a burgeoning area of analysis. While biamperometric and conductometric titrations are discussed, common redox titrations employing an indicator (e.g. iodometric titrations with starch endpoint) are ignored. Likewise, electrochemical stripping analysis, important in trace analysis, is given short shrift (half a page). The editors set a useful chapter template, but it is not followed in all cases. At the top of the first page of each chapter is a grayed box of general learning objectives, sort of a chapter overview, and most chapters begin with a very brief, often interesting historical overview. Worked numerical examples, though scarce, are found in grayed areas throughout the text. Specific and general references for further reading are a welcome sight at the end of the chapters, but in some cases are missing. Review questions and exercises finish up each chapter. Though I write many of my own exercises and problems for student practice, I--and my students--do rely on textbook authors for additional interesting challenges related to the textbook material. The number and type of end-of-chapter problems are quite variable in Analytical Chemistry. For example, the chapters on infrared and Raman spectroscopy and on basic statistics end with a sufficient number of questions (35 and 22, respectively); but, inexplicably, only 4 questions follow the discussion of acid-base equilibria, only 7 follow the chapter on liquid and thin-layer chromatography, and there are none on immunoassay. Other important topics also are slighted. Most of the end-of-chapter questions are rather uninteresting and test simple rote learning, rather than requiring the synthesis and application of the knowledge acquired (higher-level learning). I would have liked to see spreadsheet or other computer work as the focus of some questions and an appendix of answers to at least some of the exercises. Numerous minor errors were evident, especially in the first half of the book. Some were typographical, such as soulbility instead of solubility and equation of the complex instead of aquation of the complex, but others were more egregious, such as ? instead of ? and ?, which is missing the minus sign. The standard electrode potentials listed in the appendix are confusing, because while the proper values for E ° are given, the half-reactions are written as oxidations rather than as reductions. On the whole, though, the principles of the field are described clearly and accurately. I would recommend Analytical Chemistry to prospective and practicing analytical chemists as a valuable reference to many existing and emerging analytical techniques. It certainly deserves a spot on my reference shelf. As a classroom text, however, the book is less interesting. Perhaps with tighter editing and greater focus on pedagogy, the book could compete with the U.S. leaders, such as Harris and Skoog.

Power, R.B.

1994-01-01

Steam jet ejectors were for many years the workhorse of the chemical process industries for producing vacuum. With increasing emphasis on stricter pollution control, their use was curtailed. There are still many applications, however, such as those with large capacity requirements, where ejectors are the only equipment that can produce sufficient vacuum. Chapter 1 is a short overview on how to use the text. Chapter 2 discusses what an ejector is and how it works. How ejector stages work is reviewed in Chapter 3. Engineering calculations for ejector stages is thoroughly discussed in Chapter 4. In Chapter 5, contact andmore » surface condensers are reviewed, and calculation procedures are presented. The various types of pressure control are discussed in Chapter 6. Chapter 7 is an excellent review of installation of ejector vacuum systems. The final chapter of Part 2 (Chapters 3--8) thoroughly covers all aspects of operation, testing, troubleshooting and maintenance. Part 3, consisting of two chapters, is devoted to specifying and purchasing steam jet ejectors. Part 4 on other ejector applications and upgrading ejector usage also consists of two chapters.

Radiation transport around Kerr black holes

NASA Astrophysics Data System (ADS)

Schnittman, Jeremy David

This Thesis describes the basic framework of a relativistic ray-tracing code for analyzing accretion processes around Kerr black holes. We begin in Chapter 1 with a brief historical summary of the major advances in black hole astrophysics over the past few decades. In Chapter 2 we present a detailed description of the ray-tracing code, which can be used to calculate the transfer function between the plane of the accretion disk and the detector plane, an important tool for modeling relativistically broadened emission lines. Observations from the Rossi X-Ray Timing Explorer have shown the existence of high frequency quasi-periodic oscillations (HFQPOs) in a number of black hole binary systems. In Chapter 3, we employ a simple "hot spot" model to explain the position and amplitude of these HFQPO peaks. The power spectrum of the periodic X-ray light curve consists of multiple peaks located at integral combinations of the black hole coordinate frequencies, with the relative amplitude of each peak determined by the orbital inclination, eccentricity, and hot spot arc length. In Chapter 4, we introduce additional features to the model to explain the broadening of the QPO peaks as well as the damping of higher frequency harmonics in the power spectrum. The complete model is used to fit the power spectra observed in XTE J1550-564, giving confidence limits on each of the model parameters. In Chapter 5 we present a description of the structure of a relativistic alpha- disk around a Kerr black hole. Given the surface temperature of the disk, the observed spectrum is calculated using the transfer function mentioned above. The features of this modified thermal spectrum may be used to infer the physical properties of the accretion disk and the central black hole. In Chapter 6 we develop a Monte Carlo code to calculate the detailed propagation of photons from a hot spot emitter scattering through a corona surrounding the black hole. The coronal scattering has two major observable effects: the inverse-Compton process alters the photon spectrum by adding a high energy power-law tail, and the random scattering of each photon effectively damps out the highest frequency modulations in the X-ray light curve.

Essential Trends in Inorganic Chemistry (by D. M. P. Mingos)

NASA Astrophysics Data System (ADS)

Phillips, Reviewed By David A.

2000-05-01

The author has chosen to present his material in a distinctly different fashion from that of most inorganic chemistry textbook writers. Most texts are a mix of theory chapters and descriptive chapters, with the latter focusing on specific groups of elements. However, after a chapter laying out the quantum mechanical basis of the periodic table, Mingos has elected to organize the remaining chapters around vertical, horizontal, and diagonal relationships, or on isoelectronic and isostoichiometric relationships. I think this approach has worked remarkably well. Chapters 2-5 contain a wealth of information accompanied by clear, coherent discussions of the underlying principles that account for the observed trends and anomalies. Every serious inorganic chemist should have a copy of this text on his or her bookshelf. Chapter 1 is the least effective part of the book. Some of the quantum number notation is incorrect (m rather than ml , s rather than ms), some of the language is imprecise, and there are a few clear-cut errors. There is a nice discussion comparing the rmax of 2s and 2p vs 3s and 3p orbitals. However, most readers would be better served by the treatments in advanced inorganic texts such as those by Shriver or Huheey. Chapter 2 addresses vertical trends in the main-group elements. After discussing the influence of atomic size on atomic properties, Mingos describes and explains the second-row anomalies and the reversals in trends resulting from the addition of 3d and 4f subshells. He goes on to account for a variety of trends in the physical and chemical properties of main-group elements and their compounds. The chapter ends with tables summarizing a wide variety of properties, providing a wealth of information I have not seen presented in such a compact format anywhere else. Chapter 3 addresses the horizontal trends and diagonal relationships of the main-group elements. Among the highlights are discussions of the role of exchange energies in determining ionization energies, explanations of the trends in metallic-nonmetallic and ionic-covalent behavior, and comparisons of the elements in groups N and N + 10 (e.g., 3 and 13). Chapter 4 (isoelectronic and isostoichiometric relationships) is for the most part a discussion of bonding and structure. For the chemical educator this may be the most valuable part of the book. There are particularly lucid discussions of Lewis/valence bond descriptions of "hypervalent" molecules that avoid the use of d orbitals. The comparison of multicentered bonding schemes for hypervalent and electron-deficient molecules is also very nice. And not surprisingly, in view of the author's background, the discussion of catenated and cluster molecules is excellent. The final chapter applies the principles introduced in Chapters 2-4 to the d-block and f-block elements. There is a nice discussion of the differences between the properties and trends of the main group elements and the transition metals. Other topics that I think are particularly well treated include the role of compact (n - 1)d and (n - 2)f orbitals; multiple bonding; the EAN rule as a unifying theme (and when not to apply the rule); cluster compounds and isolobal fragments. The chapter concludes with a discussion of the lanthanides, actinides, and the transactinides through element 109. In the preface Mingos states that the book is intended for first- and second-year graduate students. I wholeheartedly agree, although these students may not be sophisticated enough to spot some of the errors in the text and tables. The presentation is probably too condensed for undergraduates. However, there is an abundance of material that should be of value to instructors of inorganic chemistry, particularly at the junior-senior level. In reviewing this book I picked up lots of ideas that will be incorporated into my advanced inorganic chemistry course this fall. If you love inorganic chemistry and enjoy the challenge of helping students understand the principles that bring coherence to this branch of our discipline, you will find Mingos' book to be an invaluable resource.

Account of Haly Abbas regarding the management of hydrocephalus in children: a text from medieval times.

PubMed

Aciduman, Ahmet; Arda, Berna; Aşkit, Cağatay; Belen, Deniz; Tuzcu, Kemal

2014-12-01

To present the text on hydrocephalus from Haly Abbas's book Kitāb al-Malikī / Liber Regius (The Royal Book), which was accepted as a classical textbook in the Eastern and Western worlds for a long time. The Arabic (Süleymaniye Manuscript Library, Murad Molla Collection, Nr: 1482 and Būlāḳ, 1294 /1877) and the Latin (Venice, 1492) versions of the related chapter was translated and compared to create an English text. Additionally, relevant literature was reviewed in detail. The text on hydrocephalus in Haly Abbas's The Royal Book virtually resembles Paul of Aegina's work. For hydrocephalic cases where the fluid collects between skin and pericranium, and pericranium and bone, Haly Abbas had made little change in surgical intervention; for the third type, skin incision, he preferred a T-type incision instead of an H-type. Like Paul of Aegina, Haly Abbas also did not advise any surgical intervention for the cases of hydrocephalus, where fluid accumulation is between bone and the dura mater. Haly Abbas's approach to hydrocephalus was as brave as that of his predecessors Antyllus, Oribasius, and Paulus, although the cases they dealt with were almost all cephalic hematomas. Although his chapter on the treatment of water accumulation in the head contains surgical interventions in extracranial hydrocephalic conditions, his account on hydrocephalus is extremely precise and gives adequate detail as in other chapters in his book.

Clematide, Simon; Akhondi, Saber A; van Mulligen, Erik M; Rebholz-Schuhmann, Dietrich

2015-01-01

Objective To create a multilingual gold-standard corpus for biomedical concept recognition. Materials and methods We selected text units from different parallel corpora (Medline abstract titles, drug labels, biomedical patent claims) in English, French, German, Spanish, and Dutch. Three annotators per language independently annotated the biomedical concepts, based on a subset of the Unified Medical Language System and covering a wide range of semantic groups. To reduce the annotation workload, automatically generated preannotations were provided. Individual annotations were automatically harmonized and then adjudicated, and cross-language consistency checks were carried out to arrive at the final annotations. Results The number of final annotations was 5530. Inter-annotator agreement scores indicate good agreement (median F-score 0.79), and are similar to those between individual annotators and the gold standard. The automatically generated harmonized annotation set for each language performed equally well as the best annotator for that language. Discussion The use of automatic preannotations, harmonized annotations, and parallel corpora helped to keep the manual annotation efforts manageable. The inter-annotator agreement scores provide a reference standard for gauging the performance of automatic annotation techniques. Conclusion To our knowledge, this is the first gold-standard corpus for biomedical concept recognition in languages other than English. Other distinguishing features are the wide variety of semantic groups that are being covered, and the diversity of text genres that were annotated. PMID:25948699

Mishmarot Calendars from Qumran Cave 4: Congruence and Divergence

NASA Astrophysics Data System (ADS)

Snyder, George, Jr.

1997-09-01

This study examines the calendar observed by the sect whose writings have been found in the caves of the Judean desert. Chapter I introduces the Qumran calendar as an outgrowth of the 364-day pseudo-solar year described in the astronomical chapters of 1 Enoch and defended in the Book of Jubilees. The Temple Scroll completes a calendric foundation by making canonical several summer harvest festivals not found in the Hebrew Scriptures. Chapters II through VII detail the eight mishmarot manuscripts, providing text, translation, and analysis toward understanding the fully developed calendric structure. These investigations manifest arguments that establish the beginning of the sect's lunar month at the full moon, present coordination methodologies that balance the 364-day solar year with the 354-day lunar one, and reveal two different arrangements of the festival cycle. The Conclusion gathers under the heads of Enoch and Jubilees evidence to propose two sectarian calendar traditions and brings forward other texts which could be similarly categorized. Three appendices and a glossary support the discussion from non-mishmarot calendars and presenting an eclectic six-year calendar in full detail.

Fundamentals of Polarized Light

NASA Technical Reports Server (NTRS)

Mishchenko, Michael

2003-01-01

The analytical and numerical basis for describing scattering properties of media composed of small discrete particles is formed by the classical electromagnetic theory. Although there are several excellent textbooks outlining the fundamentals of this theory, it is convenient for our purposes to begin with a summary of those concepts and equations that are central to the subject of this book and will be used extensively in the following chapters. We start by formulating Maxwell's equations and constitutive relations for time- harmonic macroscopic electromagnetic fields and derive the simplest plane-wave solution that underlies the basic optical idea of a monochromatic parallel beam of light. This solution naturally leads to the introduction of such fundamental quantities as the refractive index and the Stokes parameters. Finally, we define the concept of a quasi-monochromatic beam of light and discuss its implications.

Automatic Classification of Medical Text: The Influence of Publication Form1

PubMed Central

Cole, William G.; Michael, Patricia A.; Stewart, James G.; Blois, Marsden S.

1988-01-01

Previous research has shown that within the domain of medical journal abstracts the statistical distribution of words is neither random nor uniform, but is highly characteristic. Many words are used mainly or solely by one medical specialty or when writing about one particular level of description. Due to this regularity of usage, automatic classification within journal abstracts has proved quite successful. The present research asks two further questions. It investigates whether this statistical regularity and automatic classification success can also be achieved in medical textbook chapters. It then goes on to see whether the statistical distribution found in textbooks is sufficiently similar to that found in abstracts to permit accurate classification of abstracts based solely on previous knowledge of textbooks. 14 textbook chapters and 45 MEDLINE abstracts were submitted to an automatic classification program that had been trained only on chapters drawn from a standard textbook series. Statistical analysis of the properties of abstracts vs. chapters revealed important differences in word use. Automatic classification performance was good for chapters, but poor for abstracts.

We selected text units from different parallel corpora (Medline abstract titles, drug labels, biomedical patent claims) in English, French, German, Spanish, and Dutch. Three annotators per language independently annotated the biomedical concepts, based on a subset of the Unified Medical Language System and covering a wide range of semantic groups. To reduce the annotation workload, automatically generated preannotations were provided. Individual annotations were automatically harmonized and then adjudicated, and cross-language consistency checks were carried out to arrive at the final annotations. The number of final annotations was 5530. Inter-annotator agreement scores indicate good agreement (median F-score 0.79), and are similar to those between individual annotators and the gold standard. The automatically generated harmonized annotation set for each language performed equally well as the best annotator for that language. The use of automatic preannotations, harmonized annotations, and parallel corpora helped to keep the manual annotation efforts manageable. The inter-annotator agreement scores provide a reference standard for gauging the performance of automatic annotation techniques. To our knowledge, this is the first gold-standard corpus for biomedical concept recognition in languages other than English. Other distinguishing features are the wide variety of semantic groups that are being covered, and the diversity of text genres that were annotated. © The Author 2015.

Techniques to image the microvasculature may play an important role in imaging tumor-related angiogenesis and vasa vasorum associated with vulnerable atherosclerotic plaques. However, the microvasculature associated with these pathologies is difficult to detect using traditional B-mode ultrasound or even harmonic imaging due to small vessel size and poor differentiation from surrounding tissue. Acoustic angiography, a microvascular imaging technique that utilizes superharmonic imaging (detection of higher order harmonics of microbubble response), can yield a much higher contrast-to-tissue ratio than second harmonic imaging methods. In this paper, two dual-frequency transducers using lateral mode transmitters were developed for superharmonic detection and acoustic angiography imaging in intracavity applications. A single element dual-frequency intravascular ultrasound transducer was developed for concept validation, which achieved larger signal amplitude, better contrast-to-noise ratio (CNR), and pulselength compared to the previous work. A dual-frequency [Pb(Mg 1/3 Nb 2/3 )O 3 ]-x[PbTiO 3 ] array transducer was then developed for superharmonic imaging with dynamic focusing. The axial and lateral sizes of the microbubbles in a 200- [Formula: see text] tube were measured to be 269 and [Formula: see text], respectively. The maximum CNR was calculated to be 22 dB. These results show that superharmonic imaging with a low frequency lateral mode transmitter is a feasible alternative to thickness mode transmitters when the final transducer size requirements dictate design choices.

To present the chapter "On wound of the head and fracture of the head bone" of Kitāb al-Manṣūrī / Liber Almansoris, which was one of the early works of Rhazes. Both Arabic (Süleymaniye Manuscript Library, Ayasofya collection, Nr. 3751 and Millet Library, Feyzullah Efendi collection, Nr. 1327) and the Latin (Basileae, 1544) texts of Kitāb al-Manṣūrī / Liber Almansoris were studied, and the 26th section of the 7th chapter, entitled "Fī al-shajja kasr al-'aẓm al-ra's / De plagis capitis et fractura cranei / On wound of the head and fracture of the head bone" was translated into English and English text created. Rhazes underlined removing bone fragments in depressed and separated fractures of cranium along with protection of the dura, but he did not describe any surgical technique in this chapter. Galen's contemplation for the care of the dura with its integrity and as well his proposal to remove the bone fragments for preventing the dura from injury were the golden standards at the time that Rhazes also followed in the treatment of skull fractures.

Text-Content-Analysis based on the Syntactic Correlations between Ontologies

NASA Astrophysics Data System (ADS)

Tenschert, Axel; Kotsiopoulos, Ioannis; Koller, Bastian

The work presented in this chapter is concerned with the analysis of semantic knowledge structures, represented in the form of Ontologies, through which Service Level Agreements (SLAs) are enriched with new semantic data. The objective of the enrichment process is to enable SLA negotiation in a way that is much more convenient for a Service Users. For this purpose the deployment of an SLA-Management-System as well as the development of an analyzing procedure for Ontologies is required. This chapter will refer to the BREIN, the FinGrid and the LarKC projects. The analyzing procedure examines the syntactic correlations of several Ontologies whose focus lies in the field of mechanical engineering. A method of analyzing text and content is developed as part of this procedure. In order to so, we introduce a formalism as well as a method for understanding content. The analysis and methods are integrated to an SLA Management System which enables a Service User to interact with the system as a service by negotiating the user requests and including the semantic knowledge. Through negotiation between Service User and Service Provider the analysis procedure considers the user requests by extending the SLAs with semantic knowledge. Through this the economic use of an SLA-Management-System is increased by the enhancement of SLAs with semantic knowledge structures. The main focus of this chapter is the analyzing procedure, respectively the Text-Content-Analysis, which provides the mentioned semantic knowledge structures.

Machine translation (MT) from text, the topic of this chapter, is perhaps the heart of the GALE project. Beyond being a well defined application that stands on its own, MT from text is the link between the automatic speech recognition component and the distillation component. The focus of MT in GALE is on translating from Arabic or Chinese to English. The three languages represent a wide range of linguistic diversity and make the GALE MT task rather challenging and exciting.

The science of the stars in Danzig from Rheticus to Hevelius

NASA Astrophysics Data System (ADS)

Jensen, Derek

This dissertation asks how civic institutions (the city council and the academic gymnasium), socio-economic structures (civic and private patronage) and religion and civic ideals in the city of Danzig shaped creative thought about the science of the stars during the sixteenth and seventeenth centuries. Reciprocally, it looks at how the use of scientific knowledge created distinctive representations of the city both as it appeared to its own citizens and as it was presented to others outside of the city walls. By employing a variety of sources, including Latin texts, printed prognostications, astrological and astronomical pamphlets, handwritten marginalia, German poetry, artwork (both printed illustrations and freestanding pieces), travelers' accounts, personal correspondence and funeral sermons, I explore how those who lived in Danzig represented their observations of the stars. While concentrating on Danzig, the dissertation compares and contrasts experiences in Danzig to other places. Examples of comparisons are those in chapters 1 and 4, which compare systems of courtly patronage found in other European cities with systems of civic and private patronage found in Danzig. Chapter 2 considers the books of Peter Crüger (1580-1639), professor of mathematics and poetry in the Danzig gymnasium, and his concern to remain within the bounds of correct Lutheran doctrine. He wrote at a time when Lutherans held powerful positions within city government and in the administration of the gymnasium. In chapter 3, I focus on the writings of Peter Crüger's pupil, Andreas Gryphius (1616-1664). Gryphius later became a celebrated German poet and statesman. Understanding his stay in Danzig and his studies under Crüger, I argue, are vital to understanding his poetry, plays and prose. Chapters 5 through 7 concentrate on another of Crüger's students, namely, Johannes Hevelius (1611-1687). Chapter 5 studies Hevelius's first major publication, Selenographia (1647) and argues that Hevelius's concern to honor his city was intimately connected to the creation and final production of Selenographia . In Chapter 6, I examine the frontispiece to Hevelius's posthumously published Uranographia (1690). The frontispiece is an allegorical depiction of the "Last Judgment" of Hevelius and his astronomical works. Hevelius's "Last Judgment" resembles in form and content other judgment scene paintings in Danzig. The final chapter compares and contrasts the lives of Hevelius and Tycho Brahe (1546-1601) using a sermon given at Hevelius's funeral as the primary text of analysis.

BOOK REVIEW An Introduction to Relativity An Introduction to Relativity

NASA Astrophysics Data System (ADS)

Dray, Tevian

2011-02-01

As is clearly stated in the preface, this book is a fresh rewrite of Narlikar's published lecture notes [1] from 1978, resulting in a unique historical perspective with a modernized presentation. For workers in the field, this book provides a fascinating glimpse of the state of the art 30 years ago, but there are some inevitable idiosyncracies which might make it less useful to the beginner, especially those attempting to read this book on their own. The author is well-known for his informal, readable style, and this book is no exception. Although the treatment is overly algebraic from this reviewer's modern perspective, that is not necessarily a drawback, and does accurately reflect contemporary usage. This text is a `math first' approach to relativity, presenting the tensor calculus first, and the physics second. Not surprisingly given the author's interests, there is an emphasis on cosmological applications. After a quick review of special relativity, the book jumps right in with a fairly standard introduction to tensor calculus, followed almost immediately by chapters on Einstein's equations, the Schwarzschild solution, experimental tests, relativistic astrophysics, and black holes, followed in turn by several chapters on cosmology. This new text is a faithful adaptation of the earlier text, with essentially identical tables of contents. In fact, the only notable differences are the opening chapter summarizing special relativity, a brief new chapter on gravitational radiation, and the exclusion of a lecture on the Steady State Theory — and that material appears separately in the author's cosmology text [2]. Some of the material, such as the excellent chapter on symmetries, is largely identical to the original, but most of the material has been extensively rewritten, with most of the changes being to presentation, rather than content. There are some seldom seen gems in this book, such as the aforementioned discussion of symmetries, the extensive discussion of cosmology, a formula for Lorentz transformations in an arbitrary direction, and numerous discussions of early work in the field, complete with original references. My only real quibble with this book (apart from the use of signature (+ - - -) is that, without comment, it makes some rather sophisticated assumptions about the reader. Chapter 1, the self-described `crash course' in special relativity, expects the reader to be comfortable with standard but nontrivial manipulations of Maxwell's equations, with hyperbolic trigonometry, and to be able to comprehend a statement that Newton's first law `remains as it is' in special relativity, without any statement of the law itself. Tensor notation is also introduced much too quickly in this chapter, although this topic is revisited later in more detail. These are not unreasonable assumptions about the intended audience, who are likely to be graduate students in physics or workers in the field. But the addition of a few explanatory remarks, or an explicit statement of the intended audience, might have encouraged the less experienced reader to keep reading. In summary, this is an excellent book, which researchers in relativity will treasure for its historical perspective. Instructors of a first course in general relativity who are seeking a `math first' approach should definitely take a look, although they should be prepared to explain some missing details in the presentation.

Enhancement Of Sensing Capabilities And Functionalization Of Optical Microresonators

NASA Astrophysics Data System (ADS)

Cocking, Alexander

Optical microresonators have been demonstrated to provide a large enhancement in electric field by containing an resonant mode in a very small volume. This resonant enhancement is proportional to the quality of the resonator, which for microspheres has been demonstrated to be on the order of 1010. These devices can be leveraged to greatly improve light-matter interaction and for this reason the theoretical background of optical microresonators is discussed in the second chapter. This includes the use of COMSOL Multiphysics to model the mode structure and scattering from different resonator geometries. The second chapter also contains details on the fabrication and experimental design of optical microresonators. This includes the fabrication of fiber tapers for evanescent wave coupling into the devices. Once the theoretical framework for utilizing resonators as tools for enhancement has been established in the second chapter, we progress to the discussion of the microbubble geometry and its potential for use as an on-chip sensor system. Topics covered include design, fabrication, and theoretical analysis of the mode structure in this geometry. Modal interaction with a liquid filled microbubble is demonstrated. Additionally, the use of microbubble resonators as highly accurate temperature sensors is demonstrated experimentally and theoretically. In chapter 4 we investigate the use of silica microspheres as sensing devices; specifically, using them for the purpose of sensing nano-particles and chemicals in incredibly minute quantities. In this section microresonators are demonstrated to provide enhancement to Raman scattering from nano-scale particles. This configuration retains the traditional sensing methods of resonators by observing mode shifting and splitting in the resonance spectrum, while adding in a label-free sensing ability to determine material composition on adhered micro and nanoparticles. The fifth chapter discusses the characterization of a new class of materials known as two dimensional materials (2D materials). Typically made from single atomic sheets of transition metal dichalcogenides, they are called two dimensional due to their incredibly small thickness. Monolayers of metal dichalcogenides offer large values for optical nonlinear susceptibility and can be used to generate highly efficient nonlinear optical phenomena. This chapter seeks to understand and describe the capabilities of these materials in a context of eventually integrating them into optical microresonators to create a new class of silica-based miniaturized nonlinear optical devices. The final chapter in this dissertation covers the proposed and in-progress work related to those topics already covered in previous chapters. This includes direct growth of transition metal dichalcogenides onto microsphere resonators to create narrow linewidth microscopic lasers. Another novel photonic device consists of a single mode optical fiber etched to expose the core onto which a monolayer of 2D material is adhered. This presents the capability to create a simple photonic device which can easily be integrated as a discrete optical component capable of producing guided photoluminescence or extremely high second harmonic generation. Finally, spectral holography is discussed as a potential tool to record the phase information of light traveling through optical microresonators, adhered particles, and directly grown 2D materials.

Electrically tunable laser based on oblique heliconical cholesteric liquid crystal.

A cholesteric liquid crystal (CLC) formed by chiral molecules represents a self-assembled one-dimensionally periodic helical structure with pitch [Formula: see text] in the submicrometer and micrometer range. Because of the spatial periodicity of the dielectric permittivity, a CLC doped with a fluorescent dye and pumped optically is capable of mirrorless lasing. An attractive feature of a CLC laser is that the pitch [Formula: see text] and thus the wavelength of lasing [Formula: see text] can be tuned, for example, by chemical composition. However, the most desired mode to tune the laser, by an electric field, has so far been elusive. Here we present the realization of an electrically tunable laser with [Formula: see text] spanning an extraordinarily broad range (>100 nm) of the visible spectrum. The effect is achieved by using an electric-field-induced oblique helicoidal (OH) state in which the molecules form an acute angle with the helicoidal axis rather than align perpendicularly to it as in a field-free CLC. The principal advantage of the electrically controlled CLC OH laser is that the electric field is applied parallel to the helical axis and thus changes the pitch but preserves the single-harmonic structure. The preserved single-harmonic structure ensures efficiency of lasing in the entire tunable range of emission. The broad tuning range of CLC OH lasers, coupled with their microscopic size and narrow line widths, may enable new applications in areas such as diagnostics, sensing, microscopy, displays, and holography.

2006-01-01

Reviews the book, Psychoanalytic Psychotherapy: A Practitioner's Guide by Nancy McWilliams (see record 2004-16060-000). Nancy McWilliams' book on analytic therapy is her latest contribution to the training needs of young clinicians. The book is organized into chapters that address fundamental issues clinical trainees typically face as they work with patients. To establish the context for describing psychoanalytic work, the first chapter defines what she means by psychoanalytic therapy. The three chapters that follow address what McWilliams means by a psychoanalytic sensibility: how the therapist may be prepared for doing therapy and how the client may be prepared for the experience of psychoanalytic psychotherapy. The next three chapters address the maintenance of boundaries and basic therapy processes. Two case examples follow in chapters eight and nine, and each example is a richly evocative description of the complexity of psychoanalytic psychotherapy. The last three chapters of the book deal with the ancillary lessons of psychoanalytic therapy, the occupational hazards and gratifications of the work, and a final chapter on self-care. This is an excellent book, but it should be read together with other texts on psychoanalytic psychotherapy that describe the treatment process systematically in more technical terms. This is a book written for clinicians in training or for experienced clinicians to use in working with clinical trainees. In this sense, Nancy McWilliams has more than achieved her goal of writing a book that will introduce clinical trainees to the psychoanalytic sensibility of doing psychoanalytic psychotherapy.

A proper response to DNA damage is critical for the maintenance of genome integrity. However, it is difficult to study the in vivo kinetics and factor requirements of the damage recognition process in mammalian cells. In order to address how the cell reacts to DNA damage, we utilized a second harmonic (532 nm) pulsed Nd:YAG laser to induce highly concentrated damage in a small area in interphase cell nuclei and cytologically analyzed both protein recruitment and modification. Our results revealed for the first time the sequential recruitment of factors involved in two major DNA double-strand break (DSB) repair pathways, non-homologous end-joining (NHEJ) and homologous recombination (HR), and the cell cycle-specific recruitment of the sister chromatid cohesion complex cohesin to the damage site. In this chapter, the strategy developed to study the DNA damage response using the 532-nm Nd:YAG laser will be summarized.

In this chapter, we review basic concepts from probability theory and computational statistics that are fundamental to evolutionary genomics. We provide a very basic introduction to statistical modeling and discuss general principles, including maximum likelihood and Bayesian inference. Markov chains, hidden Markov models, and Bayesian network models are introduced in more detail as they occur frequently and in many variations in genomics applications. In particular, we discuss efficient inference algorithms and methods for learning these models from partially observed data. Several simple examples are given throughout the text, some of which point to models that are discussed in more detail in subsequent chapters.

Is the Fight against Doping in Sport a Legal Minefield like Any Other?

PubMed

Haas, Ulrich

2017-01-01

In the fight against doping, creating a level playing field across all sports is very challenging from a legal perspective. A harmonized approach presupposes first and foremost a supreme regulatory authority on a global level. This task cannot be attributed to the public sector, because there is no supranational authority of public international law capable of dealing with it. Thus, responsibility has to be assumed by a private law entity. This in turn requires complicated contractual agreements by which duties and responsibilities are transferred from the individual to the national level and from there to the top of the pyramid. In practice, this process is not only difficult and cumbersome, it also leads to an accumulation of power at the top of the sports pyramid that must be contained by organizational checks and balances, such as access to justice and the rule of law, accountability, transparency, and possibilities for the respective stakeholders to partake in the decision-making process. The weighting of all these different aspects is demanding and further complicated by the regulatory reach of the various national lawmakers. Since national laws differ considerably and a harmonized legislative approach is nowhere near in sight, a global approach in the fight against doping must push back national laws and legal concepts as much as possible. The purpose of this chapter is to give an overview on all these legal challenges. © 2017 S. Karger AG, Basel.

BOOK REVIEW: Many-Body Quantum Theory in Condensed Matter Physics—An Introduction

This is undoubtedly an ambitious book. It aims to provide a wide ranging, yet self-contained and pedagogical introduction to techniques of quantum many-body theory in condensed matter physics, without losing mathematical `rigor' (which I hope means rigour), and with an eye on physical insight, motivation and application. The authors certainly bring plenty of experience to the task, the book having grown out of their graduate lectures at the Niels Bohr Institute in Copenhagen over a five year period, with the feedback and refinement this presumably brings. The book is also of course ambitious in another sense, for it competes in the tight market of general graduate/advanced undergraduate texts on many-particle physics. Prospective punters will thus want reasons to prefer it to, or at least give it space beside, well established texts in the field. Subject-wise, the book is a good mix of the ancient and modern, the standard and less so. Obligatory chapters deal with the formal cornerstones of many-body theory, from second quantization, time-dependence in quantum mechanics and linear response theory, to Green's function and Feynman diagrams. Traditional topics are well covered, including two chapters on the electron gas, chapters on phonons and electron phonon coupling, and a concise account of superconductivity (confined, no doubt judiciously, to the conventional BCS case). Less mandatory, albeit conceptually vital, subjects are also aired. These include a chapter on Fermi liquid theory, from both semi-classical and microscopic perspectives, and a freestanding account of one-dimensional electron gases and Luttinger liquids which, given the enormity of the topic, is about as concise as it could be without sacrificing clarity. Quite naturally, the authors' own interests also influence the choice of material covered. A persistent theme, which brings a healthy topicality to the book, is the area of transport in mesoscopic systems or nanostructures. Two chapters, some fifty pages of the book, are devoted to electron transport in mesoscopic systems; the one on interacting systems is preceded by a brief account of equation of motion techniques a relative rarity in a general text, used here to provide background to subsequent discussion of the Coulomb blockade in quantum dots. So does it work, and will it find a niche beside other established, wide ranging texts? On the whole I think the answer has to be yes. To begin with, the book is well organised and user-friendly, which must surely appeal to students (and their mentors). The chapters are typically bite-sized and digestible. Each is accompanied by a summary/outlook, which in doing just that attempts to place the specific topic in a wider context, together with a set of problems that illustrate, and in many cases expand substantially on, the basic subject matter. A particularly healthy feature of the book is the extent to which the authors have sought where possible to include physical and/or material applications of basic theory, thereby enlivening old material and enhancing appreciation of the new. The first chapter on the electron gas, for example, introduces the reader to a range of material examples, including 2D heterostructures, carbon nanotubes and quantum dots. A chapter on the formalism of Green's functions takes time out to explain how the single-particle spectral function can be measured by tunnelling spectroscopy, while discussion of impurity scattering and conductivity is refreshed by consideration of weak localization in bulk and mesoscopic systems, and the phenomenon of universal conductance fluctuations. And so on: in a text that could readily descend to the purely formal, the authors have clearly taken seriously the task of incorporating relevant, topical applications of the underlying theory. In a book as wide ranging as this any reviewer is of course bound to perceive the occasional deficiency. I felt for example that some aspects of the discussion of conductance in quantum dots, notably the Coulomb blockade and the Kondo effect, were not quite up to scratch—a touch unbalanced in coverage perhaps (no serious mention of renormalization or scaling, even perturbative), with the odd conceptual error creeping in, and the Kondo effect appearing more mysterious than it really is, possibly in part because consideration of it appears before the chapter on Fermi liquid theory, in which the effect is firmly rooted. But let me not miss the bigger picture: I don't doubt this is a pretty impressive book overall, likely to have broad appeal to budding theorists and adventurous experimentalists, either as a course textbook or—for the slave to garret or lab—as a serious source for self-study. So make a space on your bookshelves.

Practical Capillary Electrophoresis, 2nd Edition by Robert Weinberger

NASA Astrophysics Data System (ADS)

Tilstra, Luanne

2001-01-01

Parts of the text are unnecessarily confusing. The confusion arises because the author assumes the reader knows some aspect of CE in detail, although the detail is not presented until a later chapter. The "Master Symbol List" in the early pages is complete for individuals who are fluent in the language of CE, but not necessarily for folks new to the field. When faced with a new abbreviation, I found it necessary to check for its presence in the master list; if the abbreviation wasn't there, I added it. For example, every CE practitioner knows that BGE stands for "background electrolyte". Although the abbreviation was clearly defined in Chapter 1, I had forgotten it by the time I got to Chapter 3. Nevertheless, the wealth of detailed information, the abundance of useful references, and the well-organized tables outweigh the few editorial problems I found.

Hanford Waste Vitrification Plant technical manual

DOE Office of Scientific and Technical Information (OSTI.GOV)

Larson, D.E.; Watrous, R.A.; Kruger, O.L.

1996-03-01

A key element of the Hanford waste management strategy is the construction of a new facility, the Hanford Waste Vitrification Plant (HWVP), to vitrify existing and future liquid high-level waste produced by defense activities at the Hanford Site. The HWVP mission is to vitrify pretreated waste in borosilicate glass, cast the glass into stainless steel canisters, and store the canisters at the Hanford Site until they are shipped to a federal geological repository. The HWVP Technical Manual (Manual) documents the technical bases of the current HWVP process and provides a physical description of the related equipment and the plant. Themore » immediate purpose of the document is to provide the technical bases for preparation of project baseline documents that will be used to direct the Title 1 and Title 2 design by the A/E, Fluor. The content of the Manual is organized in the following manner. Chapter 1.0 contains the background and context within which the HWVP was designed. Chapter 2.0 describes the site, plant, equipment and supporting services and provides the context for application of the process information in the Manual. Chapter 3.0 provides plant feed and product requirements, which are primary process bases for plant operation. Chapter 4.0 summarizes the technology for each plant process. Chapter 5.0 describes the engineering principles for designing major types of HWVP equipment. Chapter 6.0 describes the general safety aspects of the plant and process to assist in safe and prudent facility operation. Chapter 7.0 includes a description of the waste form qualification program and data. Chapter 8.0 indicates the current status of quality assurance requirements for the Manual. The Appendices provide data that are too extensive to be placed in the main text, such as extensive tables and sets of figures. The Manual is a revision of the 1987 version.« less

Classical Mechanics: A Modern Introduction

NASA Astrophysics Data System (ADS)

McCall, Martin W.

2000-12-01

Classical Mechanics is a clear introduction to the subject, combining a user-friendly style with an authoritative approach, whilst requiring minimal prerequisite mathematics - only elementary calculus and simple vectors are presumed. The text starts with a careful look at Newton's Laws, before applying them in one dimension to oscillations and collisions. More advanced applications - including gravitational orbits, rigid body dynamics and mechanics in rotating frames - are deferred until after the limitations of Newton's inertial frames have been highlighted through an exposition of Einstein's Special Relativity. The examples given throughout are often unusual for an elementary text, although they are made accessible through discussion and diagrams. Complete revision summaries are given at the end of each chapter, together with problems designed to be both illustrative and challenging. Features: * Comprehensive introduction to classical mechanics and relativity * Many novel examples, e.g. stability of the universe, falling cats, crickets bats and snooker * Includes many problems with numerical answers * Revision notes at the end of each chapter

A Method for Harmonic Sources Detection based on Harmonic Distortion Power Rate

NASA Astrophysics Data System (ADS)

Lin, Ruixing; Xu, Lin; Zheng, Xian

2018-03-01

Harmonic sources detection at the point of common coupling is an essential step for harmonic contribution determination and harmonic mitigation. The harmonic distortion power rate index is proposed for harmonic source location based on IEEE Std 1459-2010 in the paper. The method only based on harmonic distortion power is not suitable when the background harmonic is large. To solve this problem, a threshold is determined by the prior information, when the harmonic distortion power is larger than the threshold, the customer side is considered as the main harmonic source, otherwise, the utility side is. A simple model of public power system was built in MATLAB/Simulink and field test results of typical harmonic loads verified the effectiveness of proposed method.

Balancing Vibrations at Harmonic Frequencies by Injecting Harmonic Balancing Signals into the Armature of a Linear Motor/Alternator Coupled to a Stirling Machine

NASA Technical Reports Server (NTRS)

Holliday, Ezekiel S. (Inventor)

2014-01-01

Vibrations at harmonic frequencies are reduced by injecting harmonic balancing signals into the armature of a linear motor/alternator coupled to a Stirling machine. The vibrations are sensed to provide a signal representing the mechanical vibrations. A harmonic balancing signal is generated for selected harmonics of the operating frequency by processing the sensed vibration signal with adaptive filter algorithms of adaptive filters for each harmonic. Reference inputs for each harmonic are applied to the adaptive filter algorithms at the frequency of the selected harmonic. The harmonic balancing signals for all of the harmonics are summed with a principal control signal. The harmonic balancing signals modify the principal electrical drive voltage and drive the motor/alternator with a drive voltage component in opposition to the vibration at each harmonic.

An Aspect of the History of Medicine in Ancient Korea as Examined through Silla Buddhist Monks'Annotations on the "Chapter on Eliminating Disease"in the Sutra of Golden Light (Suvarnabhāsa-sūtra).

PubMed

Oh, Chaekun; Jeon, Jongwook; Shin, Dongwon

2016-12-01

Nearly nothing is known of medicine in ancient Korea due to insufficient materials. With several extant prescriptions and esoteric methods of treating diseases alone, it is impossible to gauge in depth the management of medicine during this period. If one exception were to be cited, that would be the fact that the annotations for understanding the contents on Indian medicine in the "Chapter on Eliminating Disease" in the Sutra of Golden Light, a Buddhist sutra originating from India, reflected the medical knowledge of Buddhist monks from Silla (57 BC-935 AD) who were active immediately after the nation's unification of the two other kingdoms on the Korean Peninsula (668 AD) such as Wonhyo (617-686 AD), Gyeongheung (620?-700? AD), and Seungjang (684-? AD). Along with those by other monks, these annotations are collected in the Mysterious Pivot of the Sutra of Golden Light, which was compiled by Gangyō(835-871 AD), a Japanese monk from the Heian era (794-1185 AD). Representative versions of the "Chapter on Eliminating Disease" in the Sutra of Golden Light include: a classical Chinese translation by the Indian monk Dharmakṣema (385-433 AD); the eight-volume edition by Chinese monk Baogui, which differs little from the preceding work in terms of the contents of the "Chapter on Eliminating Disease"; and the ten-volume edition by Yijing (635-713 AD), who had full-fledged knowledge of Indian medicine. When the contents of the annotations thus collected are examined, it seems that Wonhyo had not been aware of the existence of the ten-volume edition, and Gyeongheung and Seungjang most certainly used the ten-volume edition in their annotations as well. Especially noteworthy are Wonhyo's annotations on the Indian medical knowledge found in the "Chapter on Eliminating Disease" in the Sutra of Golden Light. Here, he made a bold attempt to link and understand consistently even discussions on Indian and Buddhist medicine on the basis of the traditional East Asian medical theory centering on the yin-yang and five phases (wuxing). In accordance with East Asia's theory of the seasonal five phases, Wonhyo sought to explain aspects of Indian medicine, e.g., changes in the four great elements (catvāri mahā-bhūtāni) of earth, water, fire, and wind according to seasonal factors and their effect on the internal organs; patterns of diseases such as wind (vāta)-induced disease, bile (pitta)-induced disease, phlegm (śleṣman)-induced disease, and a combination (saṃnipāta) of these three types of diseases; pathogenesis due to the indigestion of food, as pathological mechanisms centering on the theory of the mutual overcoming (xiangke) of the five phases including the five viscera (wuzang), five flavors (wuwei), and five colors (wuse). They existed in the text contents on Indian medicine, which could not be explicated well with the existing medical knowledge based on the theory of the five phases. Consequently, he boldly modified the theory of the five phases in his own way for such passages, thus attempting a reconciliation, or harmonization of disputes (hwajaeng), of the two medical systems. Such an attempt was even bolder than those by earlier annotators, and Wonhyo's annotations came to be accepted by later annotators as one persuasive explanation as well. In the case of Gyeongheung and Seungjang, who obtained and examined the ten-volume edition, a new classical Chinese translation produced following Wonhyo's death, annotated the "Chapter on Eliminating Disease" based on their outstanding proficiency in Sanskrit and knowledge of new Indian and Buddhist medicine. This fact signifies that knowledge of the eight arts of Ayurvedic medicine in India was introduced into Silla around the early 8th century. The medical knowledge of Wonhyo, Gyeongheung, and Seungjang demonstrates that intellectual circles in contemporary Silla were arenas in which not only traditional East Asian medicine as represented by works such as the Inner Canon of the Yellow Emperor (Huangdi Neijing) but also Indian medicine of Buddhism coexisted in almost real time.

The majority of the report covers LLNL's environmental monitoring programs and monitoring data for 2007: effluent and ambient air (Chapter 4); waters, including wastewater, storm water runoff, surface water, rain, and groundwater (Chapter 5); and terrestrial, including soil, sediment, vegetation, foodstuff, ambient radiation, and special status wildlife and plants (Chapter 6). Complete monitoring data, which are summarized in the body of the report, are provided in Appendix A. The remaining three chapters discuss the radiological impact on the public from LLNL operations (Chapter 7), LLNL's groundwater remediation program (Chapter 8), and quality assurance for the environmental monitoring programs (Chapter 9). The report uses Systeme International units, consistent with the federal Metric Conversion Act of 1975 and Executive Order 12770, Metric Usage in Federal Government Programs (1991). For ease of comparison to environmental reports issued prior to 1991, dose values and many radiological measurements are given in both metric and U.S. customary units. A conversion table is provided in the glossary.« less

The aim of this study was to investigate how beaker size, basket assembly, use of disk, and immersion medium impact the disintegration time of dietary supplements. The disintegration times were determined for five tablet and two capsule products. A two-station disintegration tester was used with Apparatus A or Apparatus B as described in the United States Pharmacopeia (USP) chapters, <701> and <2040>. Two beakers complying with the harmonized specifications were used, one with a volume of 1,000 mL and one with a 1,500-mL volume. The disintegration data were analyzed using ANOVA for the following factors: beaker size, equipment (App A and B) and condition (with/without disk). Two tablet products were not sensitive to any changes in the test conditions or equipment configurations. One product was only partially sensitive to the test conditions. The other products showed impact on the disintegration time for all test conditions. The results revealed that these tablet products might pass or fail current USP disintegration requirements depending on the equipment configuration. Similar results were obtained for the two investigated capsule formulations. One product might fail current USP disintegration requirements if the large beaker was used, but might pass the disintegration requirements when the small beaker was used. Hydroxy propyl methyl cellulose capsules were mostly influenced if sodium instead of a potassium buffer was used as the immersion medium. The results demonstrate that the current harmonized ICH specifications for the disintegration test are insufficient to make the disintegration test into reliable test for dietary supplements.

Possible role of cochlear nonlinearity in the detection of mistuning of a harmonic component in a harmonic complex

NASA Astrophysics Data System (ADS)

Stoelinga, Christophe; Heo, Inseok; Long, Glenis; Lee, Jungmee; Lutfi, Robert; Chang, An-Chieh

The human auditory system has a remarkable ability to "hear out" a wanted sound (target) in the background of unwanted sounds. One important property of sound which helps us hear-out the target is inharmonicity. When a single harmonic component of a harmonic complex is slightly mistuned, that component is heard to separate from the rest. At high harmonic numbers, where components are unresolved, the harmonic segregation effect is thought to result from detection of modulation of the time envelope (roughness cue) resulting from the mistuning. Neurophysiological research provides evidence that such envelope modulations are represented early in the auditory system, at the level of the auditory nerve. When the mistuned harmonic is a low harmonic, where components are resolved, the harmonic segregation is attributed to more centrally-located auditory processes, leading harmonic components to form a perceptual group heard separately from the mistuned component. Here we consider an alternative explanation that attributes the harmonic segregation to detection of modulation when both high and low harmonic numbers are mistuned. Specifically, we evaluate the possibility that distortion products in the cochlea generated by the mistuned component introduce detectable beating patterns for both high and low harmonic numbers. Distortion product otoacoustic emissions (DPOAEs) were measured using 3, 7, or 12-tone harmonic complexes with a fundamental frequency (F0) of 200 or 400 Hz. One of two harmonic components was mistuned at each F0: one when harmonics are expected to be resulted and the other from unresolved harmonics. Many non-harmonic DPOAEs are present whenever a harmonic component is mistuned. These non-harmonic DPOAEs are often separated by the amount of the mistuning (ΔF). This small frequency difference will generate a slow beating pattern at ΔF, because this beating is only present when a harmonic component is mistuned, it could provide a cue for behavioral detection of harmonic complex mistuning and may also be associated with the modulation of auditory nerve responses.

The design of a multi-harmonic step-tunable gyrotron

NASA Astrophysics Data System (ADS)

Qi, Xiang-Bo; Du, Chao-Hai; Zhu, Juan-Feng; Pan, Shi; Liu, Pu-Kun

2017-03-01

The theoretical study of a step-tunable gyrotron controlled by successive excitation of multi-harmonic modes is presented in this paper. An axis-encircling electron beam is employed to eliminate the harmonic mode competition. Physics images are depicted to elaborate the multi-harmonic interaction mechanism in determining the operating parameters at which arbitrary harmonic tuning can be realized by magnetic field sweeping to achieve controlled multiband frequencies' radiation. An important principle is revealed that a weak coupling coefficient under a high-harmonic interaction can be compensated by a high Q-factor. To some extent, the complementation between the high Q-factor and weak coupling coefficient makes the high-harmonic mode potential to achieve high efficiency. Based on a previous optimized magnetic cusp gun, the multi-harmonic step-tunable gyrotron is feasible by using harmonic tuning of first-to-fourth harmonic modes. Multimode simulation shows that the multi-harmonic gyrotron can operate on the 34 GHz first-harmonic TE11 mode, 54 GHz second-harmonic TE21 mode, 74 GHz third-harmonic TE31 mode, and 94 GHz fourth-harmonic TE41 mode, corresponding to peak efficiencies of 28.6%, 35.7%, 17.1%, and 11.4%, respectively. The multi-harmonic step-tunable gyrotron provides new possibilities in millimeter-terahertz source development especially for advanced terahertz applications.

Bioorganic Chemistry: Peptides and Proteins (edited by Sidney M. Hecht)

NASA Astrophysics Data System (ADS)

Anthony-Cahill, Spencer

1999-07-01

Sidney M. Hecht, Ed. Oxford University Press: New York, 1998. 532 pp. ISBN 0-19-508468-3. $75.00. The second volume in the Bioorganic Chemistry series edited by Sidney Hecht is an outstanding addition to the collections of all scientists who teach and/or do research in the field of protein chemistry. The coverage of current research is up to date and thus the book is of great relevance to all chemists with interest in proteins, not just to academicians. As an instructor I found numerous references to current research, which I have included in my lecture notes for the undergraduate Biochemistry course and a senior-level Protein Engineering course taught at WWU. In addition to the chapters covering a broad spectrum of protein chemistry, there are two chapters (protein structural analysis, site-directed mutagenesis) which are excellent introductions to laboratory procedures in protein chemistry and molecular biology. The first chapter is an overview of basic protein biochemistry and serves as an introduction to the rest of the book. This chapter is dispensable for readers familiar with introductory biochemistry. The chapter on chemical synthesis of peptides is an exhaustive review of solution and solid-phase methods, with numerous references. I was struck by the abundance of figures showing structures of reactants but the general lack of organic chemical mechanisms. This is true for the rest of the book as well. Presumably the chemistry is known to the intended reader (grad students, advanced undergrads); however, as a devoted pusher of electrons, I was expecting to see more mechanisms in this and subsequent chapters. Instructors will have to present this aspect of the chemistry in lecture. The relevance of peptide chemistry is underscored by accompanying chapters on peptide hormones and peptidomimetics. Taken together these three chapters provide an excellent introduction to pharmaceutical peptide chemistry. The chapter on total synthesis of proteins is one of my favorites. It outlines elegant synthetic approaches to the formidable problem of generating long peptides and is very readable. Complementing the chemical synthetic strategies is a chapter on recombinant methods for protein synthesis. Again, I found this to be an excellent review of methods that have become the sine qua non of protein structure-function studies. The application of site-directed mutagenesis to support protein biophysical studies is illustrated with relevant examples from the author's laboratory. The chapter Structural Analysis of Proteins is an informative review of lab procedures for analyzing primary sequence and posttranslational modifications. It might well serve as a lab manual, as in many cases recipes for a particular procedure are given in the text. At 70 pages the chapter on protein structure is the longest in the book. It is impressive in its level of detail while maintaining readability. This chapter not only provides an excellent introduction to protein structure in general but also highlights the interplay between computational methods (modeling, refinement) and classification of structural motifs that supports structure prediction. Four chapters further illustrate the diversity of research in the protein field. These topics include antibody catalysis, DNA-binding proteins that require zinc, the use of enzymes in organic synthesis, and protein-based materials research. Finally, two chapters deserve special mention as outstanding treatments of important theoretical concepts. The chapters on protein folding and proton transfer to and from carbon by enzymes stand out in my mind as excellent qualitative introductions to complex topics. Both are succinct, lucid presentations of the relevant theoretical considerations, with ample references to the primary literature for those seeking more quantitative development of the topics. This is an outstanding collection of reviews. If you are a peptide or protein chemist or a reader with a general interest in proteins, you will benefit from reading all or most of this book. Each chapter stands on its own, so the order of coverage during an academic term depends on the preference of the instructor. I have only minor suggestions for improvement. I found roughly a dozen typos in the figures and in the text. I prefer references at the end of each chapter rather than all together at the back of the book. The book would be enhanced by the inclusion of mechanisms for many of the cited reactions. Cofactor chemistry, metabolic pathway elucidation (xenobiotic biosynthesis), and enzyme mimics (other than antibodies) are not covered in this volume. It is debatable whether they should be. In the final analysis the editor had to make choices about what to include and he made very good ones. Perhaps some of the elegant synthetic chemistry being developed to elucidate biosynthetic pathways and enzyme mechanisms will appear in subsequent volumes. In my mind that is classical bioorganic chemistry and worthy of inclusion. In the meantime, Professor Hecht is to be congratulated for assembling yet another fine edition of readable and relevant Bioorganic Chemistry.

Genesis of a bad idea

NASA Astrophysics Data System (ADS)

Carlowicz, Michael

According to an article in Business Week (June 10), Macmillan/McGraw-Hill Inc. has agreed to custom-publish a version of its fourth-grade textbook Changing Earth in order to omit a chapter entitled “Birth of Earth.” Parents in the Cobb County, Georgia, school district complained that since the chapter does not include creationism as a theory for the origin of the universe and of Earth, the entire discussion ought to be left out.According to McGraw-Hill, customizing its textbooks is good business. Changing Earth and other such books are designed to allow teachers to build their own programs; the company is willing to customize texts because it does not want to dictate curricula, and it tries to meet demands of school districts. Business Week noted that the theory of evolution still is taught in the sixth and eighth grades, as well as high school, in Cobb County. Changing Earth also contains references to evolution in other chapters besides the one being deleted.

THE EDITORS provide a sound introduction to ethics, law and professional issues in health care. Scenarios before each chapter help the reader to digest and comprehend the information. My only criticism is that it is not directly relevant to nursing alone. Although there is some benefit in being aware of how other practitioners may be affected by these issues, another book aimed at nurses would be more appropriate. Later chapters about responding to unprofessional practice and promoting professional healthcare practice may be of more interest to nursing students and recently qualified healthcare professionals.

Relation of squeezed states between damped harmonic and simple harmonic oscillators

NASA Technical Reports Server (NTRS)

Um, Chung-In; Yeon, Kyu-Hwang; George, Thomas F.; Pandey, Lakshmi N.

1993-01-01

The minimum uncertainty and other relations are evaluated in the framework of the coherent states of the damped harmonic oscillator. It is shown that the coherent states of the damped harmonic oscillator are the squeezed coherent states of the simple harmonic oscillator. The unitary operator is also constructed, and this connects coherent states with damped harmonic and simple harmonic oscillators.

Analysis of Even Harmonics Generation in an Isolated Electric Power System

NASA Astrophysics Data System (ADS)

Kanao, Norikazu; Hayashi, Yasuhiro; Matsuki, Junya

Harmonics bred from loads are mainly odd order because the current waveform has half-wave symmetry. Since the even harmonics are negligibly small, those are not generally measured in electric power systems. However, even harmonics were measured at a 500/275/154kV substation in Hokuriku Electric Power Company after removal of a transmission line fault. The even harmonics caused malfunctions of protective digital relays because the relays used 4th harmonics at the input filter as automatic supervisory signal. This paper describes the mechanism of generation of the even harmonics by comparing measured waveforms with ATP-EMTP simulation results. As a result of analysis, it is cleared that even harmonics are generated by three causes. The first cause is a magnetizing current of transformers due to flux deviation by DC component of a fault current. The second one is due to harmonic conversion of a synchronous machine which generates even harmonics when direct current component or even harmonic current flow into the machine. The third one is that increase of harmonic impedance due to an isolated power system produces harmonic voltages. The design of the input filter of protective digital relays should consider even harmonics generation in an isolated power system.

Bi-harmonic cantilever design for improved measurement sensitivity in tapping-mode atomic force microscopy.

PubMed

Loganathan, Muthukumaran; Bristow, Douglas A

2014-04-01

This paper presents a method and cantilever design for improving the mechanical measurement sensitivity in the atomic force microscopy (AFM) tapping mode. The method uses two harmonics in the drive signal to generate a bi-harmonic tapping trajectory. Mathematical analysis demonstrates that the wide-valley bi-harmonic tapping trajectory is as much as 70% more sensitive to changes in the sample topography than the standard single-harmonic trajectory typically used. Although standard AFM cantilevers can be driven in the bi-harmonic tapping trajectory, they require large forcing at the second harmonic. A design is presented for a bi-harmonic cantilever that has a second resonant mode at twice its first resonant mode, thereby capable of generating bi-harmonic trajectories with small forcing signals. Bi-harmonic cantilevers are fabricated by milling a small cantilever on the interior of a standard cantilever probe using a focused ion beam. Bi-harmonic drive signals are derived for standard cantilevers and bi-harmonic cantilevers. Experimental results demonstrate better than 30% improvement in measurement sensitivity using the bi-harmonic cantilever. Images obtained through bi-harmonic tapping exhibit improved sharpness and surface tracking, especially at high scan speeds and low force fields.

Multiple Landslide-Hazard Scenarios Modeled for the Oakland-Berkeley Area, Northern California

USGS Publications Warehouse

Pike, Richard J.; Graymer, Russell W.

2008-01-01

With the exception of Los Angeles, perhaps no urban area in the United States is more at risk from landsliding, triggered by either precipitation or earthquake, than the San Francisco Bay region of northern California. By January each year, seasonal winter storms usually bring moisture levels of San Francisco Bay region hillsides to the point of saturation, after which additional heavy rainfall may induce landslides of various types and levels of severity. In addition, movement at any time along one of several active faults in the area may generate an earthquake large enough to trigger landslides. The danger to life and property rises each year as local populations continue to expand and more hillsides are graded for development of residential housing and its supporting infrastructure. The chapters in the text consist of: *Introduction by Russell W. Graymer *Chapter 1 Rainfall Thresholds for Landslide Activity, San Francisco Bay Region, Northern California by Raymond C.

Dynamic Coupling Between Respiratory and Cardiovascular System

NASA Astrophysics Data System (ADS)

Censi, Federica; Calcagnini, Giovanni; Cerutti, Sergio

The analysis of non-linear dynamics of the coupling among interacting quantities can be very useful for understanding the cardiorespiratory and cardiovascular control mechanisms. In this chapter RP is used to detect and quantify the degree of non-linear coupling between respiration and spontaneous rhythms of both heart rate and blood pressure variability signals. RQA turned out to be suitable for a quantitative evaluation of the observed coupling patterns among rhythms, both in simulated and real data, providing different degrees of coupling. The results from the simulated data showed that the increased degree of coupling between the signals was marked by the increase of PR and PD, and by the decrease of ER. When the RQA was applied to experimental data, PD and ER turned out to be the most significant variables, compared to PR. A remarkable finding is the detection of transient 1:2 PL episodes between respiration and cardiovascular variability signals. This phenomenon can be associated to a sub-harmonic synchronization between the two main rhythms of HR and BP variability series.

Pharmaceutical patents and some international trade issues: Canada, the United States, and NAFTA.

Tancer, R S

1993-01-01

This paper traces the evolution of a more aggressive US policy for the protection of the intellectual property rights of its citizens, individual and corporate, who do business aborad. It focuses on the pharmaceutical industry and, in particular, the harmonization of conflicting US and Canadian policies. In reconciling these policy differences, the United States unilaterally applied relatively new procedures authorized under section 301 and Special 301 of its trade laws. It also utilized the bilateral dispute mechanism mandating cooperation "in the Uruguay Round ... to improve protection of intellectual property," as provided in the Canada-United States Free Trade Agreement. These efforts were successful; Canada amended its patent law in 1993 to conform to current international practices. These changes were incorporated into the North American Free Trade Agreement (NAFTA), making it a state-of-the-art example of the protection of intellectual property rights. The intellectual property chapter of NAFTA will serve as the model for US intellectual property rights negotiations for the foreseeable future.

The Cleaning of the Parthenon West Frieze by Means of Combined IR- and UV-Radiation

NASA Astrophysics Data System (ADS)

Frantzikinaki, K.; Marakis, G.; Panou, A.; Vasiliadis, C.; Papakonstantinou, E.; Pouli, P.; Ditsa, T.; Zafiropulos, Vassilis; Fotakis, Costas

This chapter deals with the cleaning of the Parthenon West Frieze by means of an innovative laser cleaning methodology. Following a comparative study of various cleaning methods, laser cleaning was proven to be the most efficient method for the removal of loose deposits and black crusts. The laser system employed is a Q-switched Nd:YAG system emitting at the fundamental and the third harmonic frequencies designed and developed by FORTH-IESL. The system emits in two wavelength beams individually or in combination. This feature, along with possible modification of the laser parameters - energy density, number of pulses, the contribution of each beam to the final combined beam - for each individual case of encrustation and substrate (marble, monochromatic layers), leads to a safe and controlled cleaning result. The project commenced in 2002 and was completed in January 2005. Since then, the Parthenon West Frieze is on display at the Acropolis Museum in Athens, Greece.

Computational Thermodynamics of Materials Zi-Kui Liu and Yi Wang

DOE Office of Scientific and Technical Information (OSTI.GOV)

Devanathan, Ram

This authoritative volume introduces the reader to computational thermodynamics and the use of this approach to the design of material properties by tailoring the chemical composition. The text covers applications of this approach, introduces the relevant computational codes, and offers exercises at the end of each chapter. The book has nine chapters and two appendices that provide background material on computer codes. Chapter 1 covers the first and second laws of thermodynamics, introduces the spinodal as the limit of stability, and presents the Gibbs-Duhem equation. Chapter 2 focuses on the Gibbs energy function. Starting with a homogeneous system with amore » single phase, the authors proceed to phases with variable compositions, and polymer blends. The discussion includes the contributions of external electric and magnetic fields to the Gibbs energy. Chapter 3 deals with phase equilibria in heterogeneous systems, the Gibbs phase rule, and phase diagrams. Chapter 4 briefly covers experimental measurements of thermodynamic properties used as input for thermodynamic modeling by Calculation of Phase Diagrams (CALPHAD). Chapter 5 discusses the use of density functional theory to obtain thermochemical data and fill gaps where experimental data is missing. The reader is introduced to the Vienna Ab Initio Simulation Package (VASP) for density functional theory and the YPHON code for phonon calculations. Chapter 6 introduces the modeling of Gibbs energy of phases with the CALPHAD method. Chapter 7 deals with chemical reactions and the Ellingham diagram for metal-oxide systems and presents the calculation of the maximum reaction rate from equilibrium thermodynamics. Chapter 8 is devoted to electrochemical reactions and Pourbaix diagrams with application examples. Chapter 9 concludes this volume with the application of a model of multiple microstates to Ce and Fe3Pt. CALPHAD modeling is briefly discussed in the context of genomics of materials. The book introduces basic thermodynamic concepts clearly and directs readers to appropriate references for advanced concepts and details of software implementation. The list of references is quite comprehensive. The authors make liberal use of diagrams to illustrate key concepts. The two Appendices at the end discuss software requirements and the file structure, and present templates for special quasi-random structures. There is also a link to download pre-compiled binary files of the YPHON code for Linux or Microsoft Windows systems. The exercises at the end of the chapters assume that the reader has access to VASP, which is not freeware. Readers without access to this code can work on a limited number of exercises. However, results from other first principles codes can be organized in the YPHON format as explained in the Appendix. This book will serve as an excellent reference on computational thermodynamics and the exercises provided at the end of each chapter make it valuable as a graduate level textbook.

The History and Use of Our Earth's Chemical Elements: A Reference Guide (by Robert E. Krebs)

NASA Astrophysics Data System (ADS)

Bracken, Reviewed By Jeffrey D.

1999-04-01

Greenwood Press: Westport, CT, 1998. 282 pp + 25 pp glossary + 37 pp index. 15.9 x 24.1 cm. ISBN 0-313-30123-9. $39.95. This book is an excellent resource for chemical educators at the high school and college levels. The format of the text is consistent and the writing style is clear and concise, making it ideally suited for student use also. The first three chapters serve to introduce the reader to a brief history of chemistry, early models of the atom, and the development of the periodic table. Names of the contributing scientists are mentioned whenever necessary, but the overall purpose of these introductory chapters is simply to lay a foundation for the subsequent seven chapters. A complete glossary of important scientific terms mentioned in the text should allow beginning students to use this book without feeling overwhelmed. Each entry for the 112 elements contains the following information: elemental symbol, atomic number, period, common valence, atomic weight, natural state, common isotopes, properties, characteristics, abundance, natural sources, history, common uses and compounds, and safety hazards. This information is well organized, with clear headings and separate sections making the book extremely user-friendly. Readers can easily obtain the information they desire without having to skim the full entry for a chosen element. One very nice feature of this book is that the elements entries are arranged by their locations in the periodic table. For example, chapter 4 contains the alkali metals and alkaline earth metals. This organizational scheme allows one to quickly see the patterns and trends within groups of elements. This format is significantly better than arranging the elements in alphabetical order, which places the entry for sodium far removed from the entries for lithium and potassium. I would highly recommend this book to high school teachers and college chemistry professors. It is well written and is an excellent source of information for both students and educators.

Investigating the Conceptual Variation of Major Physics Textbooks

NASA Astrophysics Data System (ADS)

Stewart, John; Campbell, Richard; Clanton, Jessica

2008-04-01

The conceptual problem content of the electricity and magnetism chapters of seven major physics textbooks was investigated. The textbooks presented a total of 1600 conceptual electricity and magnetism problems. The solution to each problem was decomposed into its fundamental reasoning steps. These fundamental steps are, then, used to quantify the distribution of conceptual content among the set of topics common to the texts. The variation of the distribution of conceptual coverage within each text is studied. The variation between the major groupings of the textbooks (conceptual, algebra-based, and calculus-based) is also studied. A measure of the conceptual complexity of the problems in each text is presented.

The perception of concurrent sound objects through the use of harmonic enhancement: a study of auditory attention.

PubMed

Koulaguina, Elena; Drisdelle, Brandi Lee; Alain, Claude; Grimault, Stephan; Eck, Douglas; Vachon, François; Jolicoeur, Pierre

When the frequency of one harmonic, in a sound composed of many harmonics, is briefly mistuned and then returned to the 'in-tune' frequency and phase, observers report hearing this harmonic as a separate tone long after the brief period of mistuning - a phenomenon called harmonic enhancement. Here, we examined the consequence of harmonic enhancement on listeners' ability to detect a brief amplitude notch embedded in one of the harmonics after the period of mistuning. When present, the notch was either on the enhanced harmonic or on a different harmonic. Detection was better on the enhanced harmonic than on a non-enhanced harmonic. This finding suggests that attention was drawn to the enhanced harmonic (which constituted a new sound object) thereby easing the processing of sound features (i.e., a notch) within that object. This is the first evidence of a functional consequence of the after-effect of transient mistuning on auditory perception. Moreover, the findings provide support for an attention-based explanation of the enhancement phenomenon.

The report is prepared for the U.S. Department of Energy (DOE) by LLNL's Environmental Protection Department. Submittal of the report satisfies requirements under DOE Order 231.1A, Environmental Safety and Health Reporting, and DOE Order 5400.5, Radiation Protection of the Public and Environment. The report is distributed electronically and ismore » available at https://saer.lln.gov/, the website for the LLNL annual environmental report. Previous LLNL annual environmental reports beginning in 1994 are also on the website. Some references in the electronic report text are underlined, which indicates that they are clickable links. Clicking on one of these links will open the related document, data workbook, or website that it refers to. The report begins with an executive summary, which provides the purpose of the report and an overview of LLNL's compliance and monitoring results. The first three chapters provide background information: Chapter 1 is an overview of the location, meteorology, and hydrogeology of the two LLNL sites; Chapter 2 is a summary of LLNL's compliance with environmental regulations; and Chapter 3 is a description of LLNL's environmental programs with an emphasis on the Environmental Management System including pollution prevention. The majority of the report covers LLNL's environmental monitoring programs and monitoring data for 2008: effluent and ambient air (Chapter 4); waters, including wastewater, storm water runoff, surface water, rain, and groundwater (Chapter 5); and terrestrial, including soil, sediment, vegetation, foodstuff, ambient radiation, and special status wildlife and plants (Chapter 6). Complete monitoring data, which are summarized in the body of the report, are provided in Appendix A. The remaining three chapters discuss the radiological impact on the public from LLNL operations (Chapter 7), LLNL's groundwater remediation program (Chapter 8), and quality assurance for the environmental monitoring programs (Chapter 9). The report uses Systeme International units, consistent with the federal Metric Conversion Act of 1975 and Executive Order 12770, Metric Usage in Federal Government Programs (1991). For ease of comparison to environmental reports issued prior to 1991, dose values and many radiological measurements are given in both metric and U.S. customary units. A conversion table is provided in the glossary. The report is the responsibility of LLNL's Environmental Protection Department. Monitoring data were obtained through the combined efforts of the Environmental Protection Department; Environmental Restoration Department; Physical and Life Sciences Environmental Monitoring Radiation Laboratory; and the Hazards Control Department.« less

Content-Based Medical Image Retrieval

NASA Astrophysics Data System (ADS)

Müller, Henning; Deserno, Thomas M.

This chapter details the necessity for alternative access concepts to the currently mainly text-based methods in medical information retrieval. This need is partly due to the large amount of visual data produced, the increasing variety of medical imaging data and changing user patterns. The stored visual data contain large amounts of unused information that, if well exploited, can help diagnosis, teaching and research. The chapter briefly reviews the history of image retrieval and its general methods before technologies that have been developed in the medical domain are focussed. We also discuss evaluation of medical content-based image retrieval (CBIR) systems and conclude with pointing out their strengths, gaps, and further developments. As examples, the MedGIFT project and the Image Retrieval in Medical Applications (IRMA) framework are presented.

Static harmonization of dynamically harmonized Fourier transform ion cyclotron resonance cell.

PubMed

Zhdanova, Ekaterina; Kostyukevich, Yury; Nikolaev, Eugene

2017-08-01

Static harmonization in the Fourier transform ion cyclotron resonance cell improves the resolving power of the cell and prevents dephasing of the ion cloud in the case of any trajectory of the charged particle, not necessarily axisymmetric cyclotron (as opposed to dynamic harmonization). We reveal that the Fourier transform ion cyclotron resonance cell with dynamic harmonization (paracell) is proved to be statically harmonized. The volume of the statically harmonized potential distribution increases with an increase in the number of trap segments.

Ingredients for an Integrated Dinner: Parsley, Sage, Rosemary and Thyme

NASA Astrophysics Data System (ADS)

Baumann, Peter

2013-04-01

In 1966, Simon and Garfunkel combined the English traditional "Scarborough Fair" with a counter melody. This is one of the manifold techniques of the Kontrapunktik described by Bach around 1745 in "The Art of the Fugue": combining completely different and seemingly independent melodies (or motifs) into a coherent piece of music, pleasant for the audience. This achievement, transposed into Computer Science, could be of great benefit for geo services as we look at the currently disparate situation: On the one hand, we have metadata - traditionally, they are understood as being small in volume, but rich in content and semantics, and flexibly queryable through the rich body of technologies established over several decades of database research, centering around query languages like SQL. On the other hand, we have data themselves, such as remote sensing and other measured and observed data sets - they are considered difficult to interpret, semantic-poor, and only for clumsy download, as they are the main constituent of what we today call Big Data. The traditional advantages of databases, such as information integration, query flexibility, and scalability seem to be unavailable. These are the melodies that require a kontrapunctic harmonization, leading to a Holy Grail where different information categories enjoy individually tailored support, while an overall integrating framework allows seamless and convenient access and processing by the user. Most of the data categories to be integrated are well known in fact: ontologies, geospatial meshes, spatiotemporal arrays, and free text constitute major ingredients in this orchestration. For many of them, isolated solutions have been presented, and for some of them (like ontologies and text) integration has been achieved already; a complete harmonic integration, though, is still lacking as of today. In our talk, we detail our vision on such integration through query models and languages which merge established concepts and novel paradigms in a harmonic way. We present the EarthServer initiative which has set out to demonstrate flexible ad-hoc processing and filtering on massive Earth data sets.

We have investigated resonance effects in high-order harmonic generation (HHG) within laser-produced plasmas. We demonstrate a significantly improved harmonic yield by using two-color pump-induced enhancement and a 1 kHz pulse repetition rate. Together with an increased HHG output, the even harmonics in the cutoff region were enhanced with respect to odd harmonics. We report the observation of a resonance-induced growth in intensity of 20th harmonic in silver plasma (2×), 26th harmonic in vanadium plasma (4×), and 28th harmonic in chromium plasma (5×).

Contribution of low-frequency harmonics to Mandarin Chinese tone identification in quiet and six-talker babble background.

PubMed

Liu, Chang; Azimi, Behnam; Bhandary, Moulesh; Hu, Yi

2014-01-01

The goal of this study was to investigate Mandarin Chinese tone identification in quiet and multi-talker babble conditions for normal-hearing listeners. Tone identification was measured with speech stimuli and stimuli with low and/or high harmonics that were embedded in three Mandarin vowels with two fundamental frequencies. There were six types of stimuli: all harmonics (All), low harmonics (Low), high harmonics (High), and the first (H1), second (H2), and third (H3) harmonic. Results showed that, for quiet conditions, individual harmonics carried frequency contour information well enough for tone identification with high accuracy; however, in noisy conditions, tone identification with individual low harmonics (e.g., H1, H2, and H3) was significantly lower than that with the Low, High, and All harmonics. Moreover, tone identification with individual harmonics in noise was lower for a low F0 than for a high F0, and was also dependent on vowel category. Tone identification with individual low-frequency harmonics was accounted for by local signal-to-noise ratios, indicating that audibility of harmonics in noise may play a primary role in tone identification.

Lorenz Heister (1683-1758) was the major academic surgeon of the eighteenth century. He served as an army surgeon in a number of campaigns and eventually became the professor of anatomy and surgery at Altdorf University. In 1739, he published a comprehensive book on surgery that became the standard text on the subject. It was widely reprinted and translated into many languages. The English version was the first systematic treatise on surgery to appear in that language. The book has many chapters devoted to diseases of the mouth and their treatment.

Dependability of technical items: Problems of standardization

NASA Astrophysics Data System (ADS)

Fedotova, G. A.; Voropai, N. I.; Kovalev, G. F.

2016-12-01

This paper is concerned with problems blown up in the development of a new version of the Interstate Standard GOST 27.002 "Industrial product dependability. Terms and definitions". This Standard covers a wide range of technical items and is used in numerous regulations, specifications, standard and technical documentation. A currently available State Standard GOST 27.002-89 was introduced in 1990. Its development involved a participation of scientists and experts from different technical areas, its draft was debated in different audiences and constantly refined, so it was a high quality document. However, after 25 years of its application it's become necessary to develop a new version of the Standard that would reflect the current understanding of industrial dependability, accounting for the changes taking place in Russia in the production, management and development of various technical systems and facilities. The development of a new version of the Standard makes it possible to generalize on a terminological level the knowledge and experience in the area of reliability of technical items, accumulated over a quarter of the century in different industries and reliability research schools, to account for domestic and foreign experience of standardization. Working on the new version of the Standard, we have faced a number of issues and problems on harmonization with the International Standard IEC 60500-192, caused first of all by different approaches to the use of terms and differences in the mentalities of experts from different countries. The paper focuses on the problems related to the chapter "Maintenance, restoration and repair", which caused difficulties for the developers to harmonize term definitions both with experts and the International Standard, which is mainly related to differences between the Russian concept and practice of maintenance and repair and foreign ones.

Compressible instability of rapidly expanding spherical material interfaces

NASA Astrophysics Data System (ADS)

Mankbadi, Mina Reda

The focus herein is on the instability of a material interface formed during an abrupt release of concentrated energy as in detonative combustion, explosive dispersals, and inertial-confinement fusion. These applications are modeled as a spherical shock-tube in which high-pressure gas initially contained in a small spherical shell is suddenly released. A forward-moving shock and an inward-moving secondary shock are formed, and between them a material interface develops that separates high-density fluid from the low-density one. The wrinkling of this interface controls mixing and energy release. The interface's stability is studied with and without the inclusion of metalized particulates. A numerical scheme is developed to discretize the full nonlinear equations of the base flow, and the 3D linearized perturbed flow equations. Linearization is followed by spherical harmonic decomposition of the disturbances, thereby reducing the 3D computational domain to one-dimensional radial domain. The 3D physical nature of the disturbances is maintained throughout the procedure. An extended Roe-Pike scheme coupled with a WENO scheme is developed to capture the discontinuities and accurately predict the disturbances. In Chapter 2, the contact interface's stability is analyzed in the inviscid single-phase. The disturbances grow exponentially and the growth rate is insensitive to the radial initial-disturbance profile. For wave numbers less than 100, the results are in accordance with previous theories but clarify that compressibility reduces the growth rate. Unlike the classical RTI, the growth rate reaches saturation at high wavenumbers. The parametric studies show that for specific ratios of initial pressure and temperature, the instability can be eliminated altogether. Chapter 3 discusses the full effects of viscosity and thermal diffusivity. Although Prandtl number effects are minimal, viscous effects dampen the high-wave numbers. For a given Reynolds number there is a peak wave number at which the disturbances are most amplified. In Chapter 4, the multiphase case with metalized particles is investigated. The quasi steady gas-particle interaction forces and heat transfer decelerate the contact interface and reduce its Atwood number, which results in reducing the growth of the interfacial instabilities. A parametric study of the multiphase instability is presented to assist in controlling the instability.

Harmonic multiplication using resonant tunneling

NASA Technical Reports Server (NTRS)

Sollner, T. C. L. G.; Brown, E. R.; Goodhue, W. D.; Correa, C. A.

1988-01-01

This paper demonstrates the use of resonant-tunneling diodes as varistors for harmonic multiplication. It is shown that efficient odd-harmonic conversion is possible and that even harmonics do not appear because of the antisymmetry of the current-voltage (I-V) curve. It is also shown that, with the proper choice of resonant-tunneling structure and pump amplitude, most of the harmonic output power can be confined to a single odd-harmonic frequency. Fifth-harmonic multiplication was demonstrated with an output at 21.75 GHz and a power conversion efficiency of 0.5 percent, and a fifth-harmonic efficiency of 2.7 percent was achieved in a circuit simulation using an improved I-V curve.

Experimental Characterization of Nonlinear Harmonic Radiation from a Visible SASE FEL at Saturation

Nonlinear harmonic radiation was observed using the VISA SASE FEL at saturation. The gain lengths, spectra and energies of the three lowest SASE FEL modes were experimentally characterized. Both the measured harmonic gain lengths and center spectral wavelengths are shown to decrease with harmonic number, n, which is consistent with nonlinear harmonic theory. The measured energies for both second and third harmonics are about 1% of the fundamental; the strong second harmonic radiation ({approx} 1 {micro}J) observed is unique for low energy SASE FELs. These experimental results demonstrate for the first time the feasibility of using nonlinear harmonic SASE FELmore » radiation to produce coherent, femtosecond X-rays.« less

The using of non-linear loads generated by industrial machines may result inconsistent harmonics that do not reach the IEEE 519 - 1992 standards. This study discusses the use of single-tuned passive filters in reducing harmonics in the plastics processing industry. The system modeling using matlab / simulink simulation resulted in total harmonic distortion (THD) of 15.55%, can be reduced to 4.77% harmonics in accordance with IEEE 519 - 1992 standards. From the simulation results also seen that single-tuned passive filter can reduce the harmonics of the current 82.23% harmonic that wants to be reduced and also can reduce other orders harmonics between 7% to 8%.

We have studied ion motion effects in high harmonic generation, including shifts to the harmonics which result in degradation of the attosecond pulse train, and how to mitigate them. We have examined the scaling with intensity of harmonic emission. We have also switched the geometry of the interaction to measure, for the first time, harmonics from a normal incidence interaction. This was performed by using a special parabolic reflector with an on axis hole and is to allow measurements of the attosecond pulses using standard techniques.

A neural network model of harmonic detection

NASA Astrophysics Data System (ADS)

Lewis, Clifford F.

2003-04-01

Harmonic detection theories postulate that a virtual pitch is perceived when a sufficient number of harmonics is present. The harmonics need not be consecutive, but higher harmonics contribute less than lower harmonics [J. Raatgever and F. A. Bilsen, in Auditory Physiology and Perception, edited by Y. Cazals, K. Horner, and L. Demany (Pergamon, Oxford, 1992), pp. 215-222 M. K. McBeath and J. F. Wayand, Abstracts of the Psychonom. Soc. 3, 55 (1998)]. A neural network model is presented that has the potential to simulate this operation. Harmonics are first passed through a bank of rounded exponential filters with lateral inhibition. The results are used as inputs for an autoassociator neural network. The model is trained using harmonic data for symphonic musical instruments, in order to test whether it can self-organize by learning associations between co-occurring harmonics. It is shown that the trained model can complete the pattern for missing-fundamental sounds. The Performance of the model in harmonic detection will be compared with experimental results for humans.

Advanced Large Scale Cross Domain Temporal Topic Modeling Algorithms to Infer the Influence of Recent Research on IPCC Assessment Reports

NASA Astrophysics Data System (ADS)

Sleeman, J.; Halem, M.; Finin, T.; Cane, M. A.

2016-12-01

Approximately every five years dating back to 1989, thousands of climate scientists, research centers and government labs volunteer to prepare comprehensive Assessment Reports for the Intergovernmental Panel on Climate Change. These are highly curated reports distributed to 200 nation policy makers. There have been five IPCC Assessment Reports to date, the latest leading to a Paris Agreement in Dec. 2016 signed thus far by 172 nations to limit the amount of global Greenhouse gases emitted to producing no more than a 20 C warming of the atmosphere. These reports are a living evolving big data collection tracing 30 years of climate science research, observations, and model scenario intercomparisons. They contain more than 200,000 citations over a 30 year period that trace the evolution of the physical basis of climate science, the observed and predicted impact, risk and adaptation to increased greenhouse gases and mitigation approaches, pathways, policies for climate change. Document-topic and topic-term probability distributions are built from the vocabularies of the respective assessment report chapters and citations. Using Microsoft Bing, we retrieve 150,000 citations referenced across chapters and convert those citations to text. Using a word n-gram model based on a heterogeneous set of climate change terminology, lemmatization, noise filtering and stopword elimination, we calculate word frequencies for chapters and citations. Temporal document sets are built based on the assessment period. In addition to topic modeling, we employ cross domain correlation measures. Using the Jensen-Shannon divergence and Pearson correlation we build correlation matrices for chapter and citations topics. The shared vocabulary acts as the bridge between domains resulting in chapter-citation point pairs in space. Pairs are established based on a document-topic probability distribution. Each chapter and citation is associated with a vector of topics and based on the n most probable topics, we establish which chapter-citation pairs are most similar. We will perform posterior inferences based on Hastings -Metropolis simulated annealing MCMC algorithm to infer, from the evolution of topics starting from AR1 to AR4, assertions of topics for AR5 and potentially AR6.

BOOK REVIEW Exact Space-Times in Einstein's General Relativity Exact Space-Times in Einstein's General Relativity

NASA Astrophysics Data System (ADS)

Lake, Kayll

2010-12-01

The title immediately brings to mind a standard reference of almost the same title [1]. The authors are quick to point out the relationship between these two works: they are complementary. The purpose of this work is to explain what is known about a selection of exact solutions. As the authors state, it is often much easier to find a new solution of Einstein's equations than it is to understand it. Even at first glance it is very clear that great effort went into the production of this reference. The book is replete with beautifully detailed diagrams that reflect deep geometric intuition. In many parts of the text there are detailed calculations that are not readily available elsewhere. The book begins with a review of basic tools that allows the authors to set the notation. Then follows a discussion of Minkowski space with an emphasis on the conformal structure and applications such as simple cosmic strings. The next two chapters give an in-depth review of de Sitter space and then anti-de Sitter space. Both chapters contain a remarkable collection of useful diagrams. The standard model in cosmology these days is the ICDM model and whereas the chapter on the Friedmann-Lemaître-Robertson-Walker space-times contains much useful information, I found the discussion of the currently popular a representation rather too brief. After a brief but interesting excursion into electrovacuum, the authors consider the Schwarzschild space-time. This chapter does mention the Swiss cheese model but the discussion is too brief and certainly dated. Space-times related to Schwarzschild are covered in some detail and include not only the addition of charge and the cosmological constant but also the addition of radiation (the Vaidya solution). Just prior to a discussion of the Kerr space-time, static axially symmetric space-times are reviewed. Here one can find a very interesting discussion of the Curzon-Chazy space-time. The chapter on rotating black holes is rather brief and, for example, does not contain reference to the insights found by Pretorius and Israel [2]. This is perhaps justifiable in view of the many specialized texts devoted to the Kerr space-time (e.g. [3]). The large clear diagrams that one becomes accustomed to in this book show off the Taub-NUT (and related) space-times in the next chapter. After perhaps a somewhat standard discussion of stationary axially symmetric space-times, there is a very informative discussion of accelerating black holes. For example, the global structure of the C-metric is considered in detail. This is followed by a brief discussion of solutions for uniformly accelerating particles. The discussion of the Plebański-Demiański solutions contains two very useful flow charts that help to systematize two rather complex families of solutions. After a somewhat brief discussion of plane and pp-waves, the authors give an extensive discussion of the Kunt solutions. I note here that after this text was in production the importance of the Kunt space-times as regards the characterization of space-times by scalar curvature invariants was made clear [4]. The discussion of the Robinson-Trautman solutions that follows is extensive, containing, for example, details of the singularity structure and of the global structure. The final formal chapter in this text covers colliding plane waves. This contains, for example, discussions of the Khan-Penrose, Ferrari-Ibañez and Chandrasekhar-Xanthopoulos solutions. The text ends with a `final miscellany'. This covers a number of interesting topics, but I found the discussion of the Lemaître-Tolman solutions rather weak (compare e.g. [5]). The book has two quite useful appendices covering 2-spaces and 3-spaces of constant curvature. To conclude, I will quote from the dust jacket: `The book is an invaluable resource for both graduate students and academic researchers working in gravitational physics'. I highly recommend it.

Selective Harmonic Elimination (SHE) technique is the fundamental switching frequency scheme that is used to eliminate specific order harmonics. Its application to minimize low order harmonics in a three level inverter is proposed in this paper. The modulation strategy used here is SHEPWM and the nonlinear equations, that characterize the low order harmonics, are solved using Harmony Search Algorithm (HSA) to obtain the optimal switching angles that minimize the required harmonics and maintain the fundamental at the desired value. Total Harmonic Distortion (THD) of the output voltage is minimized maintaining selected harmonics within allowable limits. A comparison has been drawn between HSA, Genetic Algorithm (GA) and Newton Raphson (NR) technique using MATLAB software to determine the effectiveness of getting optimized switching angles.

A novel power harmonic analysis method based on Nuttall-Kaiser combination window double spectrum interpolated FFT algorithm

NASA Astrophysics Data System (ADS)

Jin, Tao; Chen, Yiyang; Flesch, Rodolfo C. C.

2017-11-01

Harmonics pose a great threat to safe and economical operation of power grids. Therefore, it is critical to detect harmonic parameters accurately to design harmonic compensation equipment. The fast Fourier transform (FFT) is widely used for electrical popular power harmonics analysis. However, the barrier effect produced by the algorithm itself and spectrum leakage caused by asynchronous sampling often affects the harmonic analysis accuracy. This paper examines a new approach for harmonic analysis based on deducing the modifier formulas of frequency, phase angle, and amplitude, utilizing the Nuttall-Kaiser window double spectrum line interpolation method, which overcomes the shortcomings in traditional FFT harmonic calculations. The proposed approach is verified numerically and experimentally to be accurate and reliable.

Two-harmonic complex spectral-domain optical coherence tomography using achromatic sinusoidal phase modulation

NASA Astrophysics Data System (ADS)

Lu, Sheng-Hua; Huang, Siang-Ru; Chou, Che-Chung

2018-03-01

We resolve the complex conjugate ambiguity in spectral-domain optical coherence tomography (SD-OCT) by using achromatic two-harmonic method. Unlike previous researches, the optical phase of the fiber interferometer is modulated by an achromatic phase shifter based on an optical delay line. The achromatic phase modulation leads to a wavelength-independent scaling coefficient for the two harmonics. Dividing the mean absolute value of the first harmonic by that of the second harmonic in a B-scan interferogram directly gives the scaling coefficient. It greatly simplifies the determination of the magnitude ratio between the two harmonics without the need of third harmonic and cumbersome iterative calculations. The inverse fast Fourier transform of the complex-valued interferogram constructed with the scaling coefficient, first and second harmonics yields a full-range OCT image. Experimental results confirm the effectiveness of the proposed achromatic two-harmonic technique for suppressing the mirror artifacts in SD-OCT images.

Exploring the chemical and biological space covered by patent applications is crucial in early-stage medicinal chemistry activities. Patent analysis can provide understanding of compound prior art, novelty checking, validation of biological assays, and identification of new starting points for chemical exploration. Extracting chemical and biological entities from patents through manual extraction by expert curators can take substantial amount of time and resources. Text mining methods can help to ease this process. To validate the performance of such methods, a manually annotated patent corpus is essential. In this study we have produced a large gold standard chemical patent corpus. We developed annotation guidelines and selected 200 full patents from the World Intellectual Property Organization, United States Patent and Trademark Office, and European Patent Office. The patents were pre-annotated automatically and made available to four independent annotator groups each consisting of two to ten annotators. The annotators marked chemicals in different subclasses, diseases, targets, and modes of action. Spelling mistakes and spurious line break due to optical character recognition errors were also annotated. A subset of 47 patents was annotated by at least three annotator groups, from which harmonized annotations and inter-annotator agreement scores were derived. One group annotated the full set. The patent corpus includes 400,125 annotations for the full set and 36,537 annotations for the harmonized set. All patents and annotated entities are publicly available at www.biosemantics.org.

A powerful, flexible text formatting program, RNF, is described. It is designed to automate many of the tedious elements of typing, including breaking a document into pages with titles and page numbers, formatting chapter and section headings, keeping track of page numbers for use in a table of contents, justifying lines by inserting blanks to give an even right margin, and inserting figures and footnotes at appropriate places on the page. The RNF program greatly facilitates both preparing and modifying a document because it allows you to concentrate your efforts on the content of the document instead of its appearance and because it removes the necessity of retyping text that has not changed.

Diseases of frogs and toads

This chapter presents information on infectious diseases of free-living frogs and toads that have completed metamorphosis. The diseases discussed in this chapter pertain principally to sub-adult and adult frogs and toads that are at least 60-90 days removed from completion of metamorphosis. The main emphasis of this chapter is the diseases found in amphibians of Canada and the United States. Diseases of recent metamorphs, larvae and amphibian eggs are presented in the chapters Diseases of Amphibian Eggs and Embryos and Diseases of Tadpoles. The smallest disease agents (viruses and bacteria) are presented first, followed by fungi, protozoa, helminths and ectoparasites. Diseases presented in this chapter are Ranaviral (iridovirus) infection Lucke frog herpesvirus (kidney cancer) Frog erythrocytic virus West Nile virus Red-leg disease (bacterial septicemia) Salmonellosis Chytrid fungal infection Basidiobolus fungi Dermosporidiosis Ichthyophoniasis Dermocystidium & Dermomycoides Myxozoa Ribeiroia flukes and Amphibian malformations Clinostomum metacercaria Aspects of each disease are presented to assist the biologist with recognition of diseases in the field. Hence, the major emphases for identification of diseases are the epizootiological aspects (host species, life stage, casualty numbers, etc) and gross findings ('lesions'). Descriptions of the microscopical, ultrastructural and cultural characteristics of each infectious agent were considered beyond the scope of this text. Detailed cultural and microscopical features of these disease agents are available in other reviews (Taylor et al., 2001; Green, 2001). Some diseases, while common in captive and zoo amphibians, are exceptionally rare in free-living frogs and toads, and therefore are omitted from this review. Among the diseases not presented are infections by chlamydia and mycobacteria, which occur principally in captive colonies of African clawed frogs (Xenopus, Hymenochirus, et al.) and northern leopard frogs (Rana pipiens). Other interesting diseases could have been presented, such as a wart-like virus infection of Japanese newts and a group of protistan parasites, referred to as Dermocystidium and Dermomycoides, in European frogs and toads. The reader is referred to Green (2001) for a review of these diseases. Amphibians have a rich diversity of helminthic parasites (Poynton and Whitaker, 2001). In general, most cestodes, trematodes and nematodes of amphibians are innocuous and not linked to specific clinical signs ('symptoms') or mortalities. An important major exception to this generalization is the trematode, Ribeiroia, which has been linked to numerous and bizarre malformations of frogs, toads and salamanders (Johnson et al., 1999, Johnson et al., 2001, Schotthoefer et al., 2003). Two genera of trematodal parasites are discussed in this chapter: Ribeiroia because they cause malformations and Clinostomum because they are large and produce visible lumps in the skin. For a review of amphibian helminths, the reader is referred to the text by Flynn (1973).

Comparing Landsat7 ETM+ and NAIP imagery for precision agriculture application in small scale farming: A case study in the south eastern part of Pittsylvania County, VA

NASA Astrophysics Data System (ADS)

Bohon, Robert Kevin, Jr.

Problem. In Ezek 36:27, God foretells that he will put his Spirit within his people and he will "do" so that Israel will obey his laws. Ezekiel 36:27 indicates a close relationship between the Spirit of God and Israel in observing the statutes and judgments of God in the Babylonian exile among the nations and after the exile. In this text, every major phrase and clause has varied interpretations or calls for further investigation. We address the following questions: What is the identity of the Spirit of God? What is the nature of the statutes and judgments of God? What is the precise relationship between the Spirit of the Lord and the people in observing the divine laws? When is the bestowal of the Spirit of God and obedience to the laws of God realized by Israel? The purpose of this research was to conduct an exegetical, intratextual, intertextual, and theological study in order to investigate further the Spirit of God in relationship to Israel in keeping the laws of God in the context of restoration in Ezek 36. Methodology. This study uses the final form and close reading of the MT in its canonical text. The method entails analytical, inductive, synchronic, and diachronic approaches to v. 27, involving OT canonical and extra-canonical Hebrew selected texts. In chapter 1, various interpretive views by scholars regarding v. 27 are presented. The views differ concerning the identity of the Spirit of God, the precise relationship between the Spirit of God and Israel in obeying the laws of God, the concept of "within," what God "does," the nature of the statutes and judgments of God, and the role of Israel as God puts his Spirit within them. In chapter 2, an exegetical investigation is undertaken for the purpose of examining the identity of the Spirit of God and the nature of the statutes and judgments of God and their relationship. The structure of v. 27 is studied in order to analyze the logical progression of the thought and intent of the author. A semantic study of the meaning of words and phrases as well as the syntax of the text is examined. Chapter 3 deals with the intratextual analysis in order to examine the connection between Ezek 36:27 and selected texts with similar vocabulary within the book of Ezekiel. In chapter 4, an intertextual study is undertaken to compare v. 27 with other selected texts in the OT with similar vocabulary for the purpose of exploring how the OT texts highlight Ezek 36:27. Chapter 5 deals with the intertextuality of Ezek 36:27 in selected extra-canonical Qumran Hebrew texts to investigate how the Spirit of God and obedience to the laws of God inform the concept of the Spirit of God and obedience to the laws of God in Ezek 36:27. In chapter 6, a theology of Ezek 36:27 is constructed based on the exegetical analysis and intratextual and intertextual investigation stated above. Conclusions. The conclusions reached by exegeting Ezek 36:27 are that: 1. The Spirit of God is God's Holy Spirit, a personal being, whom God gives to the Israelites so that they can have abundant life, for they lament that they have no life. The Spirit of God empowers or strengthens Israel to obey the laws of God of life and maintain the life they have received from the Spirit of God. 2. The statutes and judgments of God are the praxis or practical aspects of the principles of the ten words or commandments of God through which God made a covenant with Israel. As Israel obeys the laws of God, they fulfill the principle of the ten commandments of love to God and humanity. 3. God influences the mind and motivation of his people by his Spirit through the word of God as proclaimed by the prophet Ezekiel. By his Spirit, God wants to renew and soften their stony heart to be a heart of flesh in order for them to have new desires, motives, and purposes of observing his divine laws. 4. God "does" or acts through his Spirit for the sake of his holy name, characterized by grace, mercy, forbearance, love, faithfulness, and forgiveness, in renewing the mind of Israel and giving back their land in the process of restoration. 5. Israel plays an active role in the process of responding to the grace, mercy, forbearance, love, faithfulness, and forgiveness of God and their willingness to obey the word of God to return to their land. 6. The bestowal of the Spirit of God is realized by Israel while in exile among the nations but particularly when they are restored to their land. (Abstract shortened by UMI.).

Attenuation of harmonic noise in vibroseis data using Simulated Annealing

NASA Astrophysics Data System (ADS)

Sharma, S. P.; Tildy, Peter; Iranpour, Kambiz; Scholtz, Peter

2009-04-01

Processing of high productivity vibroseis seismic data (such as slip-sweep acquisition records) suffers from the well known disadvantage of harmonic distortion. Harmonic distortions are observed after cross-correlation of the recorded seismic signal with the pilot sweep and affect the signals in negative time (before the actual strong reflection event). Weak reflection events of the earlier sweeps falling in the negative time window of the cross-correlation sequence are being masked by harmonic distortions. Though the amplitude of the harmonic distortion is small (up to 10-20 %) compared to the fundamental amplitude of the reflection events, but it is significant enough to mask weak reflected signals. Elimination of harmonic noise due to source signal distortion from the cross-correlated seismic trace is a challenging task since the application of vibratory sources started and it still needs improvement. An approach has been worked out that minimizes the level of harmonic distortion by designing the signal similar to the harmonic distortion. An arbitrary length filter is optimized using the Simulated Annealing global optimization approach to design a harmonic signal. The approach deals with the convolution of a ratio trace (ratio of the harmonics with respect to the fundamental sweep) with the correlated "positive time" recorded signal and an arbitrary filter. Synthetic data study has revealed that this procedure of designing a signal similar to the desired harmonics using convolution of a suitable filter with theoretical ratio of harmonics with fundamental sweep helps in reducing the problem of harmonic distortion. Once we generate a similar signal for a vibroseis source using an optimized filter, then, this filter could be used to generate harmonics, which can be subtracted from the main cross-correlated trace to get the better, undistorted image of the subsurface. Designing the predicted harmonics to reduce the energy in the trace by considering weak reflection and observed harmonics together yields the desired result (resolution of weak reflected signal from the harmonic distortion). As optimization steps proceeds forward it is possible to observe from the difference plots of desired and predicted harmonics how weak reflections evolved from the harmonic distortion gradually during later iterations of global optimization. The procedure is applied in resolving weak reflections from a number of traces considered together. For a more precise design of harmonics SA procedure needs longer computation time which is impractical to deal with voluminous seismic data. However, the objective of resolving weak reflection signal in the strong harmonic noise can be achieved with fast computation using faster cooling schedule and less number of iterations and number of moves in simulated annealing procedure. This process could help in reducing the harmonics distortion and achieving the objective of resolving the lost weak reflection events in the cross-correlated seismic traces.

The harmonic impact of electric vehicle battery charging

NASA Astrophysics Data System (ADS)

Staats, Preston Trent

The potential widespread introduction of the electric vehicle (EV) presents both opportunities and challenges to the power systems engineers who will be required to supply power to EV batteries. One of the challenges associated with EV battery charging comes from the potentially high harmonic currents associated with the conversion of ac power system voltages to dc EV battery voltages. Harmonic currents lead to increased losses in distribution circuits and reduced life expectancy of such power distribution components as capacitors and transformers. Harmonic current injections also cause harmonic voltages on power distribution networks. These distorted voltages can affect power system loads and specific standards exist regulating acceptable voltage distortion. This dissertation develops and presents the theory required to evaluate the electric vehicle battery charger as a harmonic distorting load and its possible harmonic impact on various aspects of power distribution systems. The work begins by developing a method for evaluating the net harmonic current injection of a large collection of EV battery chargers which accounts for variation in the start-time and initial battery state-of-charge between individual chargers. Next, this method is analyzed to evaluate the effect of input parameter variation on the net harmonic currents predicted by the model. We then turn to an evaluation of the impact of EV charger harmonic currents on power distribution systems, first evaluating the impact of these currents on a substation transformer and then on power distribution system harmonic voltages. The method presented accounts for the uncertainty in EV harmonic current injections by modeling the start-time and initial battery state-of-charge (SOC) of an individual EV battery charger as random variables. Thus, the net harmonic current, and distribution system harmonic voltages are formulated in a stochastic framework. Results indicate that considering variation in start-time and SOC leads to reduced estimates of harmonic current injection when compared to more traditional methods that do not account for variation. Evaluation of power distribution system harmonic voltages suggests that for any power distribution network there is a definite threshold penetration of EVs, below which the total harmonic distortion of voltage exceeds 5% at an insignificant number of buses. Thus, most existing distribution systems will probably be able to accommodate the early introduction of EV battery charging without widespread harmonic voltage problems.

Modified ADALINE algorithm for harmonic estimation and selective harmonic elimination in inverters

NASA Astrophysics Data System (ADS)

Vasumathi, B.; Moorthi, S.

2011-11-01

In digital signal processing, algorithms are very well developed for the estimation of harmonic components. In power electronic applications, an objective like fast response of a system is of primary importance. An effective method for the estimation of instantaneous harmonic components, along with conventional harmonic elimination technique, is presented in this article. The primary function is to eliminate undesirable higher harmonic components from the selected signal (current or voltage) and it requires only the knowledge of the frequency of the component to be eliminated. A signal processing technique using modified ADALINE algorithm has been proposed for harmonic estimation. The proposed method stays effective as it converges to a minimum error and brings out a finer estimation. A conventional control based on pulse width modulation for selective harmonic elimination is used to eliminate harmonic components after its estimation. This method can be applied to a wide range of equipment. The validity of the proposed method to estimate and eliminate voltage harmonics is proved with a dc/ac inverter as a simulation example. Then, the results are compared with existing ADALINE algorithm for illustrating its effectiveness.

Harmonic template neurons in primate auditory cortex underlying complex sound processing

PubMed Central

Feng, Lei

2017-01-01

Harmonicity is a fundamental element of music, speech, and animal vocalizations. How the auditory system extracts harmonic structures embedded in complex sounds and uses them to form a coherent unitary entity is not fully understood. Despite the prevalence of sounds rich in harmonic structures in our everyday hearing environment, it has remained largely unknown what neural mechanisms are used by the primate auditory cortex to extract these biologically important acoustic structures. In this study, we discovered a unique class of harmonic template neurons in the core region of auditory cortex of a highly vocal New World primate, the common marmoset (Callithrix jacchus), across the entire hearing frequency range. Marmosets have a rich vocal repertoire and a similar hearing range to that of humans. Responses of these neurons show nonlinear facilitation to harmonic complex sounds over inharmonic sounds, selectivity for particular harmonic structures beyond two-tone combinations, and sensitivity to harmonic number and spectral regularity. Our findings suggest that the harmonic template neurons in auditory cortex may play an important role in processing sounds with harmonic structures, such as animal vocalizations, human speech, and music.

High-harmonic spectroscopy of oriented OCS molecules: emission of even and odd harmonics.

PubMed

Kraus, P M; Rupenyan, A; Wörner, H J

2012-12-07

We study the emission of even and odd high-harmonic orders from oriented OCS molecules. We use an intense, nonresonant femtosecond laser pulse superimposed with its phase-controlled second harmonic field to impulsively align and orient a dense sample of molecules from which we subsequently generate high-order harmonics. The even harmonics appear around the full revivals of the rotational dynamics. We demonstrate perfect coherent control over their intensity through the subcycle delay of the two-color fields. The odd harmonics are insensitive to the degree of orientation, but modulate with the degree of axis alignment, in agreement with calculated photorecombination dipole moments. We further compare the shape of the even and odd harmonic spectra with our calculations and determine the degree of orientation.

Unlocking higher harmonics in atomic force microscopy with gentle interactions.

PubMed

Santos, Sergio; Barcons, Victor; Font, Josep; Verdaguer, Albert

2014-01-01

In dynamic atomic force microscopy, nanoscale properties are encoded in the higher harmonics. Nevertheless, when gentle interactions and minimal invasiveness are required, these harmonics are typically undetectable. Here, we propose to externally drive an arbitrary number of exact higher harmonics above the noise level. In this way, multiple contrast channels that are sensitive to compositional variations are made accessible. Numerical integration of the equation of motion shows that the external introduction of exact harmonic frequencies does not compromise the fundamental frequency. Thermal fluctuations are also considered within the detection bandwidth of interest and discussed in terms of higher-harmonic phase contrast in the presence and absence of an external excitation of higher harmonics. Higher harmonic phase shifts further provide the means to directly decouple the true topography from that induced by compositional heterogeneity.

Application of harmonic detection technology in methane telemetry

NASA Astrophysics Data System (ADS)

Huo, Yuehua; Fan, Weiqiang

2017-08-01

Methane telemetry plays a vital role in ensuring the safe production of coal mines and monitoring the leakage of natural gas pipelines. Harmonic detection is the key technology of methane telemetry accuracy and sensitivity, but the current telemetry distance is short, the relationship between different modulation parameters is complex, and the harmonic signal is affected by noise interference. These factors seriously affect the development of harmonic detection technology. In this paper, the principle of methane telemetry based on harmonic detection technology is introduced. The present situation and characteristics of harmonic detection technology are expounded. The problems existing in harmonic detection are analyzed. Finally, the future development trend is discussed.

Characterization of Harmonic Signal Acquisition with Parallel Dipole and Multipole Detectors

NASA Astrophysics Data System (ADS)

Park, Sung-Gun; Anderson, Gordon A.; Bruce, James E.

2018-04-01

Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) is a powerful instrument for the study of complex biological samples due to its high resolution and mass measurement accuracy. However, the relatively long signal acquisition periods needed to achieve high resolution can serve to limit applications of FTICR-MS. The use of multiple pairs of detector electrodes enables detection of harmonic frequencies present at integer multiples of the fundamental cyclotron frequency, and the obtained resolving power for a given acquisition period increases linearly with the order of harmonic signal. However, harmonic signal detection also increases spectral complexity and presents challenges for interpretation. In the present work, ICR cells with independent dipole and harmonic detection electrodes and preamplifiers are demonstrated. A benefit of this approach is the ability to independently acquire fundamental and multiple harmonic signals in parallel using the same ions under identical conditions, enabling direct comparison of achieved performance as parameters are varied. Spectra from harmonic signals showed generally higher resolving power than spectra acquired with fundamental signals and equal signal duration. In addition, the maximum observed signal to noise (S/N) ratio from harmonic signals exceeded that of fundamental signals by 50 to 100%. Finally, parallel detection of fundamental and harmonic signals enables deconvolution of overlapping harmonic signals since observed fundamental frequencies can be used to unambiguously calculate all possible harmonic frequencies. Thus, the present application of parallel fundamental and harmonic signal acquisition offers a general approach to improve utilization of harmonic signals to yield high-resolution spectra with decreased acquisition time.

The studies of the high-order nonlinear optical properties of a few organic compounds (polyvinyl alcohol, polyethylene, sugar, coffee, and leaf) are reported. Harmonic generation in the laser-produced plasmas containing the molecules and large particles of above materials is demonstrated. These studies showed that the harmonic distributions and harmonic cutoffs from organic compound plasmas were similar to those from the graphite ablation. The characteristic feature of observed harmonic spectra was the presence of bluesided lobes near the lower-order harmonics.

Generations of even-order harmonics from vibrating H2+ and T2+ in the rising and falling parts of the laser field

Feng, Liqiang; Kapteyn, Henry J.; Feng, April Y.

2018-04-01

The generations of the even-order harmonics from H2+ and one of its isotope T2+ have been theoretically investigated beyond the Born-Oppenheimer approximation. Normally, the high-order harmonic generation (HHG) only contains odd-order harmonics for the orbital symmetry along the direction of laser polarization. Here, we showed that due to asymmetric harmonic emission (asymmetric half-wave profile), the even-order harmonics can be generated in the rising and the falling part of the laser field. In detail, in the lower initial vibrational state, the even-order harmonics main come from the falling part of the laser field; while as the initial vibrational state increases, the identified even-order harmonics in the falling part of the laser field are decreased; while some other even-order harmonics coming from the rising part of the laser field can be produced. The interesting phenomena have been proved through studying the spatial distributions and the time profiles of the HHG.

Harmonic imaging is a new ultrasonographic technique that is designed to improve image quality by exploiting the spontaneous generation of higher frequencies as ultrasound propagates through tissue. We studied 51 difficult-to-image patients with blinded side-by-side cineloop evaluation of endocardial border definition by harmonic versus fundamental imaging. In addition, quantitative intensities from cavity versus wall were compared for harmonic versus fundamental imaging. Harmonic imaging improved left ventricular endocardial border delineation over fundamental imaging (superior: harmonic = 71.1%, fundamental = 18.7%; similar: 10.2%; P <.001). Quantitative analysis of 100 wall/cavity combinations demonstrated brighter wall segments and more strikingly darker cavities during harmonic imaging (cavity intensity on a 0 to 255 scale: fundamental = 15.6 +/- 8.6; harmonic = 6.0 +/- 5.3; P <.0001), which led to enhanced contrast between the wall and cavity (1.89 versus 1.19, P <.0001). Harmonic imaging reduces side-lobe artifacts, resulting in a darker cavity and brighter walls, thereby improving image contrast and endocardial delineation.

Analysis of the project synthesis goal cluster orientation and inquiry emphasis of elementary science textbooks

NASA Astrophysics Data System (ADS)

Staver, John R.; Bay, Mary

The purpose of this descriptive study was to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. An inquiry classification scheme was used for the remaining segment. Four questions were answered: (1) To what extent do elementary science textbooks focus on each Project Synthesis goal cluster? (2) In which part of the text is such information found? (3) To what extent are the activities and experiments merely verifications of information already introduced in the text? (4) If inquiry is present in an activity, then what is the level of such inquiry?Eleven science textbook series, which comprise approximately 90 percent of the national market, were selected for analysis. Two units, one primary (K-3) and one intermediate (4-6), were selected for analysis by first identifying units common to most series, then randomly selecting one primary and one intermediate unit for analysis.Each randomly selected unit was carefully read, using the sentence as the unit of analysis. Each declarative and interrogative sentence in the body of the text was classified as: (1) academic; (2) personal; (3) career; or (4) societal in its focus. Each illustration, except those used in evaluation items, was similarly classified. Each activity/experiment and each miscellaneous sentence in end-of-chapter segments labelled review, summary, evaluation, etc., were similarly classified. Finally, each activity/experiment, as a whole, was categorized according to a four-category inquiry scheme (confirmation, structured inquiry, guided inquiry, open inquiry).In general, results of the analysis are: (1) most text prose focuses on academic science; (2) most remaining text prose focuses on the personal goal cluster; (3) the career and societal goal clusters receive only minor attention; (4) text illustrations exhibit a pattern similar to text prose; (5) text activities/experiments are academic in orientation, almost to the exclusion of other goal clusters; (6) end-of-chapter sentences are largely academic; (7) inquiry is absent or present only in limited forms in text activities/experiments; and (8) texts allocate only a minor portion of space to activities/experiments. Detailed findings are given as numeral, percentage, and decimal values. Discussion focuses on the implications of the results and a comparison of NSTA recommendations with the results of this analysis.

Modern Thermodynamics: From Heat Engines to Dissipative Structures (by Dilip Kodepudi and Ilya Prigogine)

NASA Astrophysics Data System (ADS)

Kovac, Reviewed By Jeffrey

1999-11-01

In the preface to his excellent textbook, Thermodynamics: Principles and Applications (Wiley-Interscience, 1971), Frank C. Andrews remarks, "It is almost an act of intellectual arrogance to write another thermodynamics text these days, so many and varied are the texts already available." Since I first read it, Andrews's comment has been my standard for judging new thermodynamics textbooks: what does a new book offer that is significantly different, and better, than one of the many fine books already on my shelf? Modern Thermodynamics by Dilip Kondepudi, Professor of Chemistry at Wake Forest University, and 1977 Nobel Laureate Ilya Prigogine does provide something quite different: a historically conscious, integrated approach to both equilibrium and nonequilibrium thermodynamics. The essential role of fluctuations in determining the properties of equilibrium and nonequilibrium systems was first elucidated by Einstein at the turn of the century. Subsequently, Lars Onsager used fluctuation theory to demonstrate the famous reciprocal relations that provide the basis for the theory of linear nonequilibrium thermodynamics. Unfortunately, thermodynamics is often taught to chemists as if it only applies to uniform equilibrium systems. Fluctuations are rarely mentioned. One of the unusual features of this book is that it begins by explicitly discussing both nonuniform and nonequilibrium systems. While most of the traditional topics of a course in chemical thermodynamics are included in this book, these applications are treated in the context of a more general formalism that can be used to discuss both linear and nonlinear nonequilibrium systems. Another interesting and important feature of this book is the integration of historical material into the presentation. While the presentation follows the usual sequencepreliminary concepts, first law, second law, etc.the ideas are placed in a historical context as they are developed. As expected, there is considerable emphasis on the contributions of Theophile De Donder, founder of the Brussels school of thermodynamics. The text is generously illustrated with portraits of many of the important figures in the development of thermodynamics. The stories and pictures help to make the subject come alive. The first 11 chapters of the book provide material for a one-semester course in equilibrium thermodynamics. The overall coverage in this section is fairly standard, including real gases, solutions, electrochemical systems, and phase transitions. As noted above, the important difference in this presentation is that the traditional topics are presented in terms of a general formalism that leads naturally to the discussion of both nonuniform and nonequilibrium systems. Chapters 12-19 explicitly consider fluctuations and stability theory, linear nonequilibrium thermodynamics, and, finally, nonlinear systems and dissipative structures. Each chapter is followed by a number of problems and students are encouraged to use Mathematica or Maple to do the more tedious calculations. A brief appendix to Chapter 1 includes some sample Mathematica codes. The book has relatively few worked examples, however, so students who need to see a lot of examples will have to look elsewhere. Unfortunately, there are no worked examples in Chapters 12-19. Since I first learned nonequilibrium thermodynamics from Prigogine's earlier book, Introduction to the Thermodynamics of Irreversible Processes (Interscience, 1961), I found the treatment in the second part of the book to be clear and logical. I think that most readers will agree. There is a nice treatment of Gaussian fluctuation theory and a proof of the Onsager reciprocal relations. Chapters 18 and 19 provide an introduction to the most important ideas in nonlinear nonequilibrium thermodynamics, including stability analysis. The book concludes with a chapter on the frontiers of research in thermodynamics. As the title promises, this book is a modern treatment of the full scope of thermodynamics emphasizing the importance of fluctuations. I hope that the appearance of this accessible treatment will stimulate faculty to rethink their teaching of thermodynamics and present it as a general and powerful way to understand both equilibrium and nonequilibrium systems.

The advent of high-harmonic generation in gases 30 years ago set the foundation for attosecond science and facilitated ultrafast spectroscopy in atoms, molecules, and solids. We explore high-harmonic generation in the solid state by means of nanostructured and ion-implanted semiconductors. We use wavelength-selective microscopic imaging to map enhanced harmonic emission and show that the generation medium and the driving field can be locally tailored in solids by modifying the chemical composition and morphology. This enables the control of high-harmonic technology within precisely engineered solid targets. We demonstrate customized high-harmonic wave fields with wavelengths down to 225 nanometers (ninth-harmonic order of 2-micrometer laser pulses) and present an integrated Fresnel zone plate target in silicon, which leads to diffraction-limited self-focusing of the generated harmonics down to 1-micrometer spot sizes.

Rates of change of the earth's magnetic field measured by recent analyses

NASA Technical Reports Server (NTRS)

Harrison, C. G. A.; Huang, Qilin

1990-01-01

Typical rates of change of the earth's magnetic field are presented as a function of the earth's spherical harmonics. Harmonics up to the eight degree are analyzed. With the increase in the degree of the harmonics an increase in the relative rate of change can be observed. For higher degrees, the rate of change can be predicted. This enables a differentiation between harmonics originating in the core and harmonics caused by crustal magnetization. The westward drift of the magnetic field depends on the longitudinal gradient of the field. In order to determine the longitudinal motions, harmonics up to degree 20 can be utilized. The average rate of secular acceleration increases with the degree of harmonics from 0.001 deg/sq yr for a dipole term to an average of 0.05 deg/sq yr for degree eight harmonics.

High-frequency harmonic imaging of the eye.

Silverman, Ronald H; Coleman, D Jackson; Ketterling, Jeffrey A; Lizzi, Frederic L

2005-01-01

PURPOSE: Harmonic imaging has become a well-established technique for ultrasonic imaging at fundamental frequencies of 10 MHz or less. Ophthalmology has benefited from the use of fundamentals of 20 MHz to 50 MHz. Our aim was to explore the ability to generate harmonics for this frequency range, and to generate harmonic images of the eye. METHODS: The presence of harmonics was determined in both water and bovine vitreous propagation media by pulse/echo and hydrophone at a series of increasing excitation pulse intensities and frequencies. Hydrophone measurements were made at the focal point and in the near- and far-fields of 20 MHz and 40 MHz transducers. Harmonic images of the anterior segment of the rabbit eye were obtained by a combination of analog filtering and digital post-processing. RESULTS: Harmonics were generated nearly identically in both water and vitreous. Hydrophone measurements showed the maximum second harmonic to be -5 dB relative to the 35 MHz fundamental at the focus, while in pulse/echo the maximum harmonic amplitude was -15dB relative to the fundamental. Harmonics were absent in the near-field, but present in the far-field. Harmonic images of the eye showed improved resolution. CONCLUSION: Harmonics can be readily generated at very high frequencies, and at power levels compliant with FDA guidelines for ophthalmology. This technique may yield further improvements to the already impressive resolutions obtainable in this frequency range. Improved imaging of the macular region, in particular, may provide significant improvements in diagnosis of retinal disease.

2011-06-01

This paper investigates the extraction of acoustic signatures from small boats using a passive sonar system. Noise radiated from a small boats consists of broadband noise and harmonically related tones that correspond to engine and propeller specifications. A signal processing method to automatically extract the harmonic structure of noise radiated from small boats is developed. The Harmonic Extraction and Analysis Tool (HEAT) estimates the instantaneous fundamental frequency of the harmonic tones, refines the fundamental frequency estimate using a Kalman filter, and automatically extracts the amplitudes of the harmonic tonals to generate a harmonic signature for the boat. Results are presented that show the HEAT algorithms ability to extract these signatures. © 2011 Acoustical Society of America

Thermodynamic properties of \\text{C}{{\\text{d}}0.50} \\text{Z}{{\\text{n}}0.50} Se alloy are studied using quasi harmonic model for pressure range 0-10 GPa and temperature range 0-1000 K. The structural optimization is obtained by self consistent field calculations and full-potential linear muffin-tin orbital method with GGA+U as an exchange correlation functional where U=2.3427 eV is the hubbard potential. The effects of temperature and pressure on the bulk modulus, Helmholtz free energy, internal energy, entropy, Debye temperature, Grüneisen parameter, thermal expansion coefficient and heat capacities of the material are observed and discussed. The bulk modulus, Helmholtz free energy and Debye temperature are found to decrease with increasing temperature while there is an increasing behavior when the pressure rises. Whereas internal energy has increasing trend with rises in temperature and it almost remains insensitive to pressure. The entropy of the system increases (decreases) with a rise of pressure (temperature).

Comparison of Fine Structures of Electron Cyclotron Harmonic Emissions in Aurora

NASA Astrophysics Data System (ADS)

Labelle, J. W.; Dundek, M.

2015-12-01

Recent discoveries of emissions at four and five times the electron cyclotron frequency in aurora occuring under daylit conditions motivated the modification of radio receivers at South Pole Station, Antarctica, to measure fine structure of such emissions during two consecutive austral summers, 2013-4 and 2014-5. The experiment recorded 347 emission events over 376 days of observation. The seasonal distribution of these events revealed that successively higher harmonics require higher solar zenith angles for occurrence, as expected if they are generated at locations where the upper hybrid frequency matches the cyclotron harmonic, which for higher harmonics requires higher electron densities which are associated with higher solar zenith angles. Detailed examination of 21 cases in which two harmonics occur simultaneously showed that only rarely, about ten percent of the time, are the frequencies of the fine structures of the emissions in exact integer ratio (e.g., 3:2, 4:3, or 5:4 depending on which combination of harmonics is observed). In the remaining approximately ninety percent of the cases, the higher harmonic occurred at a lower ratio than the appropriate integer ratio, as expected if the harmonics are generated independently at their separate matching conditions in the bottomside ionosphere, where the upper hybrid frequency increases with altitude while the gyroharmonics decrease with altitude. (The bottomside is the most likely source of the emissions, since from there the mode converted Z-modes have access to ground-level.) Taken together, these results suggest that the dominant mechanism for the higher harmonics is independent generation at locations where the upper hybrid frequency matches each harmonic, i.e., at a separate source altitude for each harmonic. Generation of higher harmonics through coalescence of lower harmonic waves explains at most a small minority of events.

The Sciences: An Integrated Approach, 2nd Edition (by James Trefil and Robert M. Hazen)

NASA Astrophysics Data System (ADS)

Hoffman, Reviewed By Megan M.

2000-01-01

"You're going to teach the organic chemistry section of the Natural Science class?" - one of my biology colleagues asked me last semester - "Better you than me!" "You are?" added a chemistry professor, with interest. Yet these same people ardently believe that all our students should have a basic understanding of carbon's remarkable bonding capabilities and how they relate to life on Earth. If our art or economics majors can learn about organic chemistry and genetics and astronomy, our faculty should be able to teach those same topics, regardless of their acknowledged specialties. The basis of a scientifically literate society is not expertise in specific arcane subfields of science. Scientific literacy is a general understanding of what science is, what science can and cannot do, and what scientific accomplishments have occurred over the centuries. If you subscribe to this definition of scientific literacy, James Trefil and Robert M. Hazen's The Sciences: An Integrated Approach can help you and your general science students. The self-avowed purpose of this text is to address science illiteracy in America. Trefil and Hazen propose that the best way to combat scientific illiteracy is to provide integrated science courses that focus on a broad understanding of science, rather than the specialized knowledge available to a science major. The new edition of The Sciences has been influenced by the 1996 publication of the National Research Council's National Science Education Standards. While the first edition of Trefil and Hazen's book admirably addressed the integration of the natural and physical sciences, in this second edition, the authors have increased the connections between science and real-world situations and have made a more conscious effort to emphasize the process of science and the overlapping nature of scientific disciplines. The text is based on 25 "scientific concepts", one per chapter. These concepts are clearly explained in relatively jargon-free language and are then tied explicitly to familiar situations and life experiences. For instance, a power outage at a baseball game helps set the scene for quantum mechanics and Heisenberg's uncertainty principle, while jump-starting a car illustrates the conversion of energy from potential through kinetic to chemical. Most of the fine pedagogical features of the first edition have been continued, including descriptions of relevant technologies, historical aspects of various discoveries, and clear descriptions of mathematical approaches to the topics. The second edition of The Sciences has increased the accessibility of science and scientific concepts by adding several new features to the successful features of the first edition: "The Ongoing Process of Science" addresses current scientific questions; "Stop and Think" encourages students to consider further implications of the topic at hand; and "Science News" provides excerpts from the periodical of the same name. In addition, previous features that highlighted connections to human physiology have been broadened to include all living things, thus allowing students to make connections between the familiar and the more abstract, for instance magnetic navigation in birds (Electricity and Magnetism), upright human posture (Plate Tectonics) and blood clotting (The Chemical Bond). A final addition to each chapter is "Great Ideas Across the Sciences", which ties the Great Idea on which the chapter is based to each of the natural sciences. This latter addition is one that students might easily overlook, but it has great potential for opening class discussion on how, for instance, the science of entropy relates to weather, arthritis, volcanoes, and gasoline use (Chapter 4). Trefil and Hazen offer a basis for understanding physics, chemistry, biology, earth science, and cosmology. While the text and figures provide a basic description of these topics, this book will not produce physicists, chemists, etc. Keep the general-science purpose of the text in mind when you begin to feel that the chapters on your favorite topic are leaving out details or ideas that you consider crucial to scientific literacy in your area. My first impression of the chapter on Classical and Modern Genetics was that it did not spend enough time on Mendel and his foundational contributions to biology. Consequently, I went well beyond the text material in my lecture on Mendelian genetics. To my regret, I learned that this extra, "crucial" material was more intimidating than enlightening. While there are sure to be critics who will wish that certain topics were covered in more depth or who will want topics added or deleted, my conclusion after teaching from this book is that Trefil and Hazen have provided a clear, well-considered, and extremely useful text for a general science course.

Harmonics arise naturally from the resonances in strings and pipes. A video demonstration (Ruiz 2016 YouTube: Tuba Harmonics (https://youtu.be/souhEzOP9c4)) is provided where a tubist (coauthor Holmes) produces a phenomenal 24 harmonics using a single tuba pipe length by controlling the buzz of his lips. The frequencies of the harmonics, measured with the free software program Audacity, fall excellently on a linear fit using a spreadsheet. The skillful musical production of so many harmonics with a fixed pipe length is an extraordinary illustration of physics.

Harmonic magneto-electric response in GaFeO3

2018-04-01

GaFeO3 is a well-known multiferroic material. Like optical second harmonic generation, it also generates radio frequency (RF) second harmonic due to its non-centrosymmetric orthorhombic structure. The harmonic RF response also features a magneto-electric character comparable in prominence to that of the fundamental response. We measured complex parts of the fundamental and the second harmonic over 80 K to 300 K. The second harmonic permittivity and its phase angle change sign at the spin glass transition temperature Tg = 200 K and becomes dispersive above ˜280 K.

BOOK REVIEW: A First Course in General Relativity (Second Edition) A First Course in General Relativity (Second Edition)

NASA Astrophysics Data System (ADS)

Poisson, Eric

2010-05-01

A few years ago, in my review of Sean Carroll's book in Classical and Quantum Gravity [1], I wrote that while the 1970s was the decade of Weinberg [2] and Misner, Thorne and Wheeler [3], and while the eighties was the decade of Schutz [4] and Wald [5], the 2000s was clearly the decade of Hartle [6] and Carroll [7]. In my opinion, these books continue to stand out in the surprisingly dense crowd of introductory textbooks on general relativity. At the dawn of this new decade I look forward to see what fresh pedagogical insights will be produced next, and who will be revealed as the winners of the 2010s. It is, of course, much too early to tell, but Schutz is back, and he will set the standard just as he did back in 1985. This is the long-awaited second edition of his `First Course', a short, accessible, and very successful introduction to general relativity. The changes from the first edition are modest: Schutz wisely refrained from bloating the text with new topics, and limited himself to updating his discussion of gravitational-wave sources and detectors, neutron-star and black-hole astrophysics, and suggestions for further reading. Most importantly, he completely rewrote the chapter on cosmology, a topic that has evolved enormously since the first edition. The book begins in chapter 1 with a beautiful review of special relativity that emphasizes spacetime geometry and stays away from an algebraic approach based on the Lorentz transformation, which appears only later in the chapter. This is followed up in chapters 2 and 3 with an introduction to vector and tensor analysis in flat spacetime. The point of view is modern (tensors are defined as linear mapping of vectors and one-forms into real numbers) but the presentation is very accessible and avoids an overload of mathematical fine print. In chapter 4 the book introduces the spacetime description of fluids; it is here that the energy-momentum tensor makes its first appearance. The move to curved spacetime is tackled next. In chapter 5 the principle of equivalence is used to motivate the notion that gravity is a manifestation of spacetime curvature. Tensor calculus in curved spacetime is approached gently, by first working through a generalization to curvilinear coordinates. A systematic introduction to differential geometry is provided in chapter 6; here the reader is initiated in Riemannian manifolds, covariant differentiation, parallel transport, geodesics, the curvature tensors, and the Bianchi identities. This is a formidable chapter, but the student is guided by a sure hand, and the presentation is both beautiful and accessible. The next two chapters bring differential geometry to physics. In chapter 7 the reader learns how to formulate the laws of physics in a curved spacetime, and in chapter 8 the Einstein field equations are finally formulated. The chapter ends with a thorough treatment of the weak-field limit in the Lorenz gauge. The following chapters present applications of the theory. Chapter 9 is devoted to gravitational waves: propagation, detection, generation, energy balance, and astrophysical sources. Here, as always, the discussion is accessible and fully up-to-date. I could identify one weakness, which I have noted in many other textbooks (this is a pet peeve of mine, which seems to be turning into an obsession): the quadrupole formula for the gravitational-wave field is derived on the basis of the linearized theory, without warning the reader that the derivation does not apply to self-gravitating systems. This is, however, compensated by a major strength: Schutz's derivation of the energy carried off by gravitational waves is based on a beautiful physical argument that bypasses the construction of an energy-momentum tensor for the gravitational-wave field; the complexities associated with such a construction are well known, and it is nice to see that Schutz has found a nice way around. In chapter 10 the exact theory is applied to stellar structure, and in chapter 11 the student is introduced to black holes. A large part of the chapter is devoted to the study of geodesic motion in Schwarzschild spacetime, and this allows Schutz to make contact with the classical tests of general relativity: perihelion advance and light deflection. The singular behaviour of the Schwarzschild coordinates at the event horizon is described in detail. This reveals another weakness of the book: the Kruskal coordinates are simply written down, with no derivation and little motivation; it is a pity that Schutz did not choose to introduce the Eddington--Finkelstein coordinates, or the Painlevé-Gullstand coordinates, as easier alternatives. The chapter ends with a general discussion of black holes (including their place in astrophysics and a description of the Hawking effect) and a detailed presentation of the Kerr solution. The last chapter (chapter 12) is devoted to cosmology, and this is the part of the book that was the most thoroughly revised. The presentation begins with the enunciation of the cosmological principle and a derivation of the Friedmann-Lemaitre models. It continues with a discussion of cosmological dynamics in the presence of pressureless matter, radiation, and a cosmological constant (of which nobody wanted to be reminded at the time of the first edition). It concludes with an up-to-date review of cosmological measurements and a (very) brief history of the Universe, from the big bang to inflation, to recombination, to structure formation. The presentation of general relativity and its applications contained in this book is suitable for undergraduate students who would prefer the standard `math-first approach' to Hartle's `physics-first approach'. The student will learn the essentials of differential geometry in a gentle way, and will then apply these tools to physics in curved spacetime; all of this can be accomplished in a brisk one-semester course. The book leaves out many topics than can be found in more advanced texts, such as Lie differentiation, differential forms, Killing vectors, the more abstract formulation of differential geometry (in terms of charts and diffeomorphisms), and the Lagrangian formulation of general relativity. This limitation of scope is wise: Schutz masterly covers the essentials in an efficient and small package, and relegates all refinements to further reading in other textbooks; this is a sound learning strategy. To conclude I will state that I just love this book. I love it today as much as I did when I first came across it as an undergraduate student. The revisions bring the book up-to-date, and they ensure that Schutz's text will remain in the pantheon of introductory general relativity books for many years to come.

Resource Economics is a text for students with a background in calculus, intermediate microeconomics, and a familiarity with the spreadsheet software Excel. The book covers basic concepts, shows how to set up spreadsheets to solve dynamic allocation problems, and presents economic models for fisheries, forestry, nonrenewable resources, stock pollutants, option value, and sustainable development. Within the text, numerical examples are posed and solved using Excel's Solver. Through these examples and additional exercises at the end of each chapter, students can make dynamic models operational, develop their economic intuition, and learn how to set up spreadsheets for the simulation of optimization of resource and environmental systems.

Frequency-chirp rates of harmonics driven by a few-cycle pulse

DOE Office of Scientific and Technical Information (OSTI.GOV)

Murakami, M.; Mauritsson, J.; Gaarde, M.B.

2005-08-15

We present numerical calculations of the time-frequency characteristics of cutoff harmonics generated by few-cycle laser pulses. We find that for driving pulses as short as three optical cycles, the adiabatic prediction for the harmonic chirp rate is very accurate. This negative chirp is so large that the resulting bandwidth causes substantial overlap between neighboring harmonics, and the harmonic phase therefore appears to not vary in time or frequency. By adding a compensating positive chirp to the driving pulse, which reduces the harmonic bandwidth and allows for the appearance of the negative chirp, we can measure the harmonic chirp rates. Wemore » also find that the positive chirp on the driving pulse causes the harmonics to shift down in frequency. We show that this counterintuitive result is caused by the change in the strong field continuum dynamics introduced by the variation of the driving frequency with time.« less

Automated detection and characterization of harmonic tremor in continuous seismic data

NASA Astrophysics Data System (ADS)

Roman, Diana C.

2017-06-01

Harmonic tremor is a common feature of volcanic, hydrothermal, and ice sheet seismicity and is thus an important proxy for monitoring changes in these systems. However, no automated methods for detecting harmonic tremor currently exist. Because harmonic tremor shares characteristics with speech and music, digital signal processing techniques for analyzing these signals can be adapted. I develop a novel pitch-detection-based algorithm to automatically identify occurrences of harmonic tremor and characterize their frequency content. The algorithm is applied to seismic data from Popocatepetl Volcano, Mexico, and benchmarked against a monthlong manually detected catalog of harmonic tremor events. During a period of heightened eruptive activity from December 2014 to May 2015, the algorithm detects 1465 min of harmonic tremor, which generally precede periods of heightened explosive activity. These results demonstrate the algorithm's ability to accurately characterize harmonic tremor while highlighting the need for additional work to understand its causes and implications at restless volcanoes.

Expansion into lattice harmonics in cubic symmetries

2018-05-01

On the example of a few sets of sampling directions in the Brillouin zone, this work shows how important the choice of the cubic harmonics is on the quality of approximation of some quantities by a series of such harmonics. These studies led to the following questions: (1) In the case that for a given l there are several independent harmonics, can one use in the expansion only one harmonic with a given l?; (2) How should harmonics be ordered: according to l or, after writing them in terms of (x4 + y4 + z4)n (x2y2z2)m, according to their degree q = n + m? To enable practical applications of such harmonics, they are constructed in terms of the associated Legendre polynomials up to l = 26. It is shown that electron momentum densities, reconstructed from experimental data for ErGa3 and InGa3, are described much better by harmonics ordered with q.

BOOK REVIEW: Principles of Plasma Spectroscopy

NASA Astrophysics Data System (ADS)

Osterheld, A. L.

1998-08-01

This book gives a comprehensive treatment of plasma spectroscopy, the quantitative study of line and continuous radiation from high temperature plasmas. This highly interdisciplinary field combines elements of atomic, plasma and statistical physics, and has wide application to simulations and diagnostics of laboratory and astrophysical plasmas. Plasma spectroscopy is naturally intertwined with magnetic and inertial fusion energy science. Radiative processes in plasmas are important in the design of fusion facilities, and can be used to diagnose and control conditions in fusion plasmas. In turn, fusion scientists and facilities have played a central role in developing plasma spectroscopy theory and applications. The book covers radiation from plasmas, spectral line broadening, atomic processes in plasmas and level kinetic models, radiative transfer and applications to spectroscopic plasma diagnostics. It is successful both as an introductory text and as a source book of theoretical and experimental research. The book presents a broad development of the theoretical foundations of these topics, and discusses the seminal papers and critical experiments. There is a strong emphasis on applications of plasma spectroscopy, primarily to plasma diagnostics and calculations of radiative cooling rates. Extensive references (current through the end of 1995) point readers to original material and detailed discussions of advanced topics. Of course, a single text cannot treat all aspects of plasma spectroscopy in depth. The strongest and most detailed section of the book is a long chapter on spectral line broadening. For me, the most significant omission is lack of a discussion of laser assisted transitions which can occur in plasmas produced by high intensity lasers. The book was intentionally written to be accessible to young researchers and graduate students. The level is roughly that of a graduate text. It assumes some familiarity with quantum mechanics and statistical thermodynamics, but develops most of the advanced concepts. Plasma spectroscopy is widely used by non-specialists, and the level and organization of the book are suited to use by researchers developing applications of plasma spectroscopic techniques. Finally, the specialist will profit from the comprehensive overview and excellent bibliography presented. The author is highly qualified to write a general book on the spectroscopy of plasmas. Professor Griem has worked in the field of plasma spectroscopy for more than four decades. He is the author of Plasma Spectroscopy (1964, McGraw-Hill), the first general, quantitative book on the subject of radiation from plasmas, as well as Spectral Line Broadening by Plasmas (1974, Academic Press). Both of these monographs were tremendously influential books. In addition to his long career at the University of Maryland, Professor Griem has worked extensively with numerous research groups in the United States of America and Europe. The depth and breadth of his experience is reflected in the book. The present book is largely new, rather than an update of the 1964 monograph. The two books have a similar organization, especially in the chapters introducing the classical and quantum theories of radiation. The later chapters of the two books diverge strongly as the present text incorporates a vast amount of modern material. The nomenclature and formalism have been updated, and I find this book more accessible than Professor Griem's earlier texts. The other significant changes are that the present book omits the problems at the end of the chapters, many of the tables of numerical results, and the chapters on plasma sources and detectors. While the tables of atomic and line shape results contained in the original book were extremely useful, they have been updated and extended in more recent works. I enthusiastically recommend this book to all scientists interested in the spectroscopy of hot plasmas. Early in his career, Professor Griem wrote the seminal book on plasma spectroscopy. It is gratifying that as a senior scientist he has written a comprehensive monograph incorporating the past three decades of development in the field he so strongly influenced. It is certain to become a coveted and classic book.

High-throughput diagnosis of potato cyst nematodes in soil samples.

2015-01-01

Potato cyst nematode (PCN) is a damaging soilborne pest of potatoes which can cause major crop losses. In 2010, a new European Union directive (2007/33/EC) on the control of PCN came into force. Under the new directive, seed potatoes can only be planted on land which has been found to be free from PCN infestation following an official soil test. A major consequence of the new directive was the introduction of a new harmonized soil sampling rate resulting in a threefold increase in the number of samples requiring testing. To manage this increase with the same staffing resources, we have replaced the traditional diagnostic methods. A system has been developed for the processing of soil samples, extraction of DNA from float material, and detection of PCN by high-throughput real-time PCR. Approximately 17,000 samples are analyzed each year using this method. This chapter describes the high-throughput processes for the production of float material from soil samples, DNA extraction from the entire float, and subsequent detection and identification of PCN within these samples.

Wireless Damage Location Sensing System

Woodard, Stanley E. (Inventor); Taylor, Bryant Douglas (Inventor)

2012-01-01

A wireless damage location sensing system uses a geometric-patterned wireless sensor that resonates in the presence of a time-varying magnetic field to generate a harmonic response that will experience a change when the sensor experiences a change in its geometric pattern. The sensing system also includes a magnetic field response recorder for wirelessly transmitting the time-varying magnetic field and for wirelessly detecting the harmonic response. The sensing system compares the actual harmonic response to a plurality of predetermined harmonic responses. Each predetermined harmonic response is associated with a severing of the sensor at a corresponding known location thereof so that a match between the actual harmonic response and one of the predetermined harmonic responses defines the known location of the severing that is associated therewith.

Perturbing laser field dependent high harmonic phase modulations

A perturbing laser pulse modulates and controls the phase of the high harmonic radiation driven by an intense fundamental pulse. Thus, a structured wave front can impress a specific spatial phase onto the generated high harmonic wave front. This modulation procedure leads to all-optical spatial light modulators for VUV or XUV radiation created by high harmonic generation. Here, through theoretical analysis and experiment, we study the correlation between the high harmonic phase modulations and the perturbing laser field amplitude and phase, providing guidelines for practical high harmonic spatial light modulators. In addition, we show that the petahertz optical oscilloscope for measuring electric fields of a perturbing beam is most robust using low order harmonics, far from the cut-off.

Imaging with Second-Harmonic Generation Nanoparticles

NASA Astrophysics Data System (ADS)

Hsieh, Chia-Lung

Second-harmonic generation nanoparticles show promise as imaging probes due to their coherent and stable signal with a broad flexibility in the choice of excitation wavelength. In this thesis, we developed and demonstrated barium titanate nanoparticles as second-harmonic radiation imaging probes. We studied the absolute second-harmonic generation efficiency of the nanoparticles on single-particle level. The polarization dependent second-harmonic signal of single nanoparticles was studied in detail. From the measured polar response, we were able to find the orientation of the nanoparticle. We developed a biochemical interface for using the second-harmonic nanoprobes as biomarkers, including in vitro cellular imaging and in vivo live animal imaging. The nanoparticles were surface functionalized with primary amine groups for stable colloidal dispersion. We achieved specific labeling of the second-harmonic nanoprobes via immunostaining where the antibodies were covalently conjugated onto the nanoparticles. We observed no toxicity of the functionalized nanoparticles to biological cells. The coherent second-harmonic signal radiated from the nanoparticles offers opportunities for new imaging techniques. Using interferometric detection, namely harmonic holography, both amplitude and phase of the second-harmonic field can be captured. Through digital beam propagation, three-dimensional field distribution, reflecting three-dimensional distribution of the nanoparticles, can be reconstructed. We achieved a scan-free three-dimensional imaging of nanoparticles in biological cells with sub-micron spatial resolution by using the harmonic holographic microscope. We further exploited the coherent second-harmonic signal for imaging through scattering media by performing optical phase conjugation of the second-harmonic signal. We demonstrated an all-digital optical phase conjugation of the second-harmonic signal originated from a nanoparticle by combining harmonic holography and dynamic computer generated holography using a spatial light modulator. The phase-conjugated second-harmonic scattered field retraced the scattering trajectory and formed a clean focus on the nanoparticle placed inside a scattering medium. The nanoparticle acted as a beacon of light; it helped us find the tailored wavefront for concentrating light at the nanoparticle inside the scattering medium. We also demonstrated imaging through a thin scattering medium by raster-scanning the phase-conjugated focus in the vicinity of the beacon nanoparticle, in which a clear image of a target placed behind a ground glass diffuser was obtained.

BOOK REVIEW: The Odd Quantum

NASA Astrophysics Data System (ADS)

Reynolds, Helen

2000-03-01

The Odd Quantum is aiming to be odd. Falling between being a quantum mechanics textbook and a `popular' science book, it aims to convey something of the substance of quantum mechanics without being overly technical or professional. It does not shy away from the mathematics of the subject or resort solely to analogy and metaphor, as so often is the case. Books aimed at the lay reader tend to take on a particular aspect of quantum mechanics, for example, wave-particle duality, and can do little more than hint at the complexity of the subject. This book is more than a textbook on quantum mechanics; it gives the reader a comprehensive account of history and an appreciation of the nature of quantum mechanics. The introductory chapters deal with the earlier part of the century and the thinking of that time. The approach is familiar, as are the stories that Treiman tells, but he also manages to convey the speed with which ideas changed and the excitement this brought to the physics community. Classical ideas of force and energy are dealt with succinctly but with sufficient depth to set up the reader for what is to come; Maxwell's equations and a brief glimpse at relativity are included. This is followed by a brief description of what the author terms the `old' quantum mechanics, in effect a highly readable tour around black body radiation and spectroscopy and the models of the atom that emerged from them. The `new' quantum mechanics begins about a third of the way through the book, and in a chapter entitled `Foundations' starts gently but rapidly moves into a detailed mathematical treatment. This section, of necessity, relapses into the style of a textbook and covers a lot of ground quickly. It is at this point that the non-specialist popular science readers for whom Treiman has written this book may become a little bemused. Concepts such as non-degeneracy and operators come thick and fast. It is difficult to imagine an educated non-physicist with little mathematical ability keeping track of the equations and their meaning. However, the text continues to be accessible and moves swiftly from `quantum classics' such as the harmonic oscillator to electrical conductivity and the collapse of stars. Reassuringly, Treiman takes time out to ask `What's going on?' where he considers the question of how probabilities get converted into `facts' when things are measured. His own fascination with the subject comes through as he considers the different interpretations of quantum mechanics. The chapter on `building blocks' starts in 1932 when ` ... it could seem that all the basic building blocks of the whole world were at last in hand'. Swiftly and succinctly it moves through to the standard model, acknowledging that a closer look would ` ... quickly carry us far afield into highly technical thickets'. The final chapter tackles the more difficult subject of quantum field theory. This is a very swift journey through quantum electrodynamics and quantum chromodynamics. It is the final summary that stands out, however. The author reminds us what to marvel about: the miracles of quantum theory that are ` ... outrageous to common sense and intuition'. This is a useful book for any science department. It will be of particular use to those of us who studied the subject some time ago and who need to refresh their memories, for example teachers of A-level physics. The asides about `what is going on' and the history that is included make it a `book' rather than a `textbook'. First-year undergraduates, or just possibly motivated and mathematically able A-level students, would also benefit. Beware, however. The mathematics is not trivial and you would arguably need to have met it before in order to cope. Although the book occasionally relapses into textbook style you are left with a sense of the wonder of the subject and an appreciation of the beauty of the mathematics that underpins it.

Dynamics and control of instrumented harmonic drives

NASA Technical Reports Server (NTRS)

Kazerooni, H.; Ellis, S. R. (Principal Investigator)

1995-01-01

Since torque in harmonic drives is transmitted by a pure couple, harmonic drives do not generate radial forces and therefore can be instrumented with torque sensors without interference from radial forces. The installation of torque sensors on the stationary component of harmonic drives (the Flexipline cup in this research work) produce backdrivability needed for robotic and telerobotic compliant maneuvers. Backdrivability of a harmonic drive, when used as torque increaser, means that the output shaft can be rotated via finite amount of torque. A high ratio harmonic drive is non-backdrivable because its output shaft cannot be turned by applying a torque on it. This article first develops the dynamic behavior of a harmonic drive, in particular the non-backdrivability, in terms of a sensitivity transfer function. The instrumentation of the harmonic drive with torque sensor is then described. This leads to a description of the control architecture which allows modulation of the sensitivity transfer function within the limits established by the closed-loop stability. A set of experiments on an active hand controller, powered by a DC motor coupled to an instrumented harmonic drive, is given to exhibit this method's limitations.

Managing Legal Texts in Requirements Engineering

Otto, Paul N.; Antón, Annie I.

Laws and regulations are playing an increasingly important role in requirements engineering and systems development. Monitoring systems for requirements and policy compliance has been recognized in the requirements engineering community as a key area for research. Similarly, legal compliance is critical in systems development, especially given that non-compliance can result in both financial and criminal penalties. Working with legal texts can be very challenging, however, because they contain numerous ambiguities, cross-references, domain-specific definitions, and acronyms, and are frequently amended via new statutes, regulations, and case law. Requirements engineers and compliance auditors must be able to identify relevant legal texts, extract requirements and other key concepts, and monitor compliance. This chapter surveys research efforts over the past 50 years in handling legal texts for systems development. This survey can aid requirements engineers and auditors to better specify, test, and monitor systems for compliance.

The recently introduced notion of a quantum group is discussed conceptually and then related to deformed harmonic oscillators ('q-harmonic oscillators'). Two developments in applying q-harmonic oscillators are reviewed: q-coherent states and the q-symplecton.

Integrating the progress that has been made on a daily basis since it was jointly commissioned in 2013 by the French National Academy of Medicine (Biotechnology Committee XX, Prof Emmanuel-Alain Cabanis) and the Technologies Academy (Pr Jean de Kervasdoué), this report, covering such a vast subject, can only represent one step in a long process. Summarized here in a volume compatible with the Bulletin, it makes reference to the full report (52 pages ; 22 pages of text, 4 pages of references, a 20-page glossary for physicians, plus 522 figures spanning 6 pages), which is available on the Academy's website. The six chapters first define "health" (WHO) and "informatics" and provide a brief history. The first chapter, on technologies, is divided into "bad" news (cybercrime, ecological risks) and advances relevant to health. The next four chapters describe the contribution of digitization to patient management, ranging from "fragile" individuals (from the gamete to old age and dependency) to healthy subjects trained to work in hostile situations (scuba diving to space exploration), and finally research. The last chapter proposes 7 areas for progress: expansion of the national imaging and communications platforms, stimulation of the medical robotics industry, extension of telemedicine to all medical and surgical specialties, support for drug dispensing and therapeutic education, and foundation of a European portal for m-health certification, research prioritization according to multiyear health plans, and reinforcement of mathematic education, starting in primary school (see: "La main à la pâte" ("Going hands-on").

High harmonic spectrum of a quasi-monochromatic pump that interacts with isotropic media consists of only odd-order harmonics. Addition of a secondary pump, e.g. a static field or the second harmonic of the primary pump, can results with generation of both odd and even harmonics of the primary pump. We propose a method for quasi-phase matching of only the even-order harmonics of the primary pump. We formulate a theory for this process and demonstrate it numerically. We also show that it leads to attosecond pulse trains with constant carrier envelop phase and high repetition rate.

We demonstrate the quasi-phase-matching of a group of harmonics generated in Ag multi-jet plasma using tunable pulses in the region of 1160 - 1540 nm and their second harmonic emission. The numerical treatment of this effect includes microscopic description of the harmonic generation, propagation of the pump pulse, and the propagation of the generated harmonics. We obtained more than 30-fold growth of harmonics at the conditions of quasi-phase-matching in the region of 35 nm using eight-jet plasma compared with the case of imperforated plasma.

High harmonic generation in gases is developing rapidly as a soft X-ray femtosecond light-source for applications. This requires control over all the harmonics characteristics and in particular, spatial properties have to be kept very good. In previous literature, measurements have always included several harmonics contrary to applications, especially spectroscopic applications, which usually require a single harmonic. To fill this gap, we present here for the first time a detailed study of completely isolated harmonics. The contribution of the surrounding harmonics has been totally suppressed using interferential filtering which is available for low harmonic orders. In addition, this allows to clearly identify behaviors of standard odd orders from even orders obtained by frequency-mixing of a fundamental laser and of its second harmonic. Comparisons of the spatial intensity profiles, of the spatial coherence and of the wavefront aberration level of 5ω at 160 nm and 6ω at 135 nm have then been performed. We have established that the fundamental laser beam aberrations can cause the appearance of a non-homogenous donut-shape in the 6ω spatial intensity distribution. This undesirable effect can be easily controlled. We finally conclude that the spatial quality of an even harmonic can be as excellent as in standard generation.

On the importance of preserving the harmonics and neighboring partials prior to vocoder processing: implications for cochlear implants.

Pre-processing based noise-reduction algorithms used for cochlear implants (CIs) can sometimes introduce distortions which are carried through the vocoder stages of CI processing. While the background noise may be notably suppressed, the harmonic structure and/or spectral envelope of the signal may be distorted. The present study investigates the potential of preserving the signal's harmonic structure in voiced segments (e.g., vowels) as a means of alleviating the negative effects of pre-processing. The hypothesis tested is that preserving the harmonic structure of the signal is crucial for subsequent vocoder processing. The implications of preserving either the main harmonic components occurring at multiples of F0 or the main harmonics along with adjacent partials are investigated. This is done by first pre-processing noisy speech with a conventional noise-reduction algorithm, regenerating the harmonics, and vocoder processing the stimuli with eight channels of stimulation in steady speech-shaped noise. Results indicated that preserving the main low-frequency harmonics (spanning 1 or 3 kHz) alone was not beneficial. Preserving, however, the harmonic structure of the stimulus, i.e., the main harmonics along with the adjacent partials, was found to be critically important and provided substantial improvements (41 percentage points) in intelligibility.
