Auditory Processing of Temporal Fine Structure by Brian C J Moore Pdf

The book is concerned with changes in the perception of sound that are associated with hearing loss and aging. Hearing loss affects about 7% of the population in developed countries, and the proportion is increasing as the average age of the population increases. The audiogram is the most widely used diagnostic tool in audiology clinics around the world. The audiogram involves measuring the threshold for detecting sounds of different frequencies. Sometimes the audiogram is the only diagnostic tool that is used. However, hearing problems are not completely characterized by the audiogram. Two individuals with similar audiograms may show very different abilities in the detection and discrimination of sounds at above-threshold levels. Also, a person may have hearing difficulties despite having an audiogram that is within the range conventionally considered as ‘normal’. One factor that may influence the discrimination of sounds, especially the ability to understand speech in background sounds, is sensitivity to temporal fine structure (TFS). This monograph reviews the role played by TFS in masking, pitch perception, speech perception, and spatial hearing, and concludes that cues derived from TFS play an important role in all of these. Evidence is reviewed suggesting that cochlear hearing loss reduces the ability to use TFS cues. Also, the ability to use TFS declines with increasing age even when the audiogram remains normal. This provides a new dimension to the changes in hearing associated with aging, a topic that is currently of great interest in view of the increasing proportion of older people in the population. The study of the role of TFS in auditory processing has been a hot topic in recent years. While there have been many research papers on this topic in specialized journals, there has been no overall review that pulls together the different research findings and presents and interprets them within a coherent framework. This monograph fills this gap. Contents:Processing of Sound in the Auditory System and Neural Representation of Temporal Fine StructureThe Role of TFS in MaskingThe Role of TFS in Pitch PerceptionThe Role of TFS in Speech PerceptionThe Influence of Hearing Loss and Age on the Binaural Processing of TFSOverview, Conclusions and Practical Implications Readership: Medical professionals, academics and clinicians in hearing, life science students and biomedical researchers. Key Features:Sensitivity to temporal fine structure (TFS) in sound is currently a hot topic, but no other book focuses on this topicThe book provides a critical review and interpretation of data on sensitivity to TFS and how sensitivity is affected by hearing loss and ageThe author has published extensively in this areaKeywords:Hearing;Hearing Loss;Age;Temporal Fine Structure;Envelope;Hearing Impairment

The Thermohaline Finestructure of the Ocean by K. N. Fedorov Pdf

The Thermohaline Finestructure of the Ocean is a five-chapter text that describes the fine-scale stratification phenomenon in the ocean and the physical processes that participate in its formation and govern its evolution. After an introduction to the concept of thermohaline finestructure of the ocean, this book goes on presenting some methodological aspects in connection with the finestructure measurements in the ocean. The next chapters examine the complex interrelations between the fine-scale stratification of the ocean water. The remaining chapters explore several important physical processes, such as molecular diffusion, convection, turbulence, internal gravity waves, inertial motions, and mean currents. This book is written for physical oceanographers and specialists in other related branches of research.

Fine Structure of Solar Radio Bursts by Gennady P. Chernov Pdf

The study of the fine structure of solar radio emissions is key to understanding plasma processes in the solar corona. It remains a reliable means for both diagnosing the corona and verifying the results of laboratory plasma experiments on wave-wave and wave-particle interactions. This monograph provides a comprehensive review of the fine structure of solar radio bursts. Based on the diversity of experimental data resulting from the progress made in observational techniques, the validity of various theoretical models is reexamined. The book serves as an up-to-date reference work for all researchers in this field.

Fine Structure Immunocytochemistry by Gareth Griffiths Pdf

Electron microscopy in the biological sciences can be divided into two disciplines. The first, concerned with high resolution detail of particles or periodic structures, is mostly based on sound theoretical principles of physics. The second, by far the larger discipline, is interested in the information obtainable from thin sections. The theoretical back ground to those groups of techniques for preparing and looking at thin sections is often inexact and "loose", for want of a better word. What should be chemistry is often closer to alchemy. This kind of electron microscopy is often enshrined with mystical recipes, handed down from generation to generation. Admittedly, many of the processes involved, such as those required to embed tissue in epoxy resins, involve multiple interconnected steps, which make it difficult to follow the details of anyone of these steps. If all these steps are shrouded in some mystery, however, can one really trust the final image that emerges on the EM screen? When we present the data in some semi quantitative form is there really no better way to do it than to categorize the parameters with ++, +/-, etc? What happens when one labels the sections with antibodies? Does the whole business necess arily need to be more of an "art" than a "science"? Upon reflecting on these problems in 1981, I had the impression that many of the multi-authored textbooks that existed then (and that have appeared since) tended to exacerbate or at least perpetuate this

Fine Structure by Sam Hughes Pdf

Fledgling physicist Ching-Yu Kuang has discovered a Rosetta Stone for all of physics, a treasure trove of advanced scientific breakthroughs beyond all imagination. Exotic energy, teleportation, FTL, parallel universes and near-infinitely more wonders are just within reach; a promise of paradise. But every attempt to exploit this new science results in sabotage, chaos and destruction. And the laws of science themselves are changing with each experiment, locking out the new discoveries, directly altering the universe to make what should be possible impossible. While Ching watches, humanity's future is being stolen. Because there's something wrong with his world. There's a fundamental flaw, a defect in its structure...

The Fine Structure of Algal Cells by John D. Dodge Pdf

The Fine Structure of Algal Cells is a hybrid between a review and a comprehensive descriptive work on fine structure of algae. Such fine structural data are important for any consideration of the classification of algae and for attempting to analyze their phylogenetic relationships. Fine-structure has provided many vital keys to the understanding of the interrelationships and phylogeny of the algae. Notably, the trend in algal fine structure work is toward use of electron microscopy to try to understand the functions of cells and organelles under both normal and experimental conditions. This book brings together information which has been gathered by electron microscopists. It considers 13 classes of algae: Chlorophyceae, Haptophyceae, Prasinophyceae, Bacillariophyceae, Chloromonadophyceae, Phaeophyceae, Euglenophyceae, Dinophyceae, Eustigmatophyceae, Cryptophyceae, Xanthophyceae, Rhodophyceae, and Chrysophyceae. It covers the main structural features of the various classes and the organelles present in typical cells. The book also describes the algal cell covering, flagella, pyrenoid, eyespot, nucleus, and ejectile organelles,as well as membranes, envelope, and stroma of algal chloroplasts. Lastly, it also explains the algal cell division. This book will help students visualize and compare algal structure, and at the same time provide enough references so that research workers can enter the literature to find out more precise details from the original sources.

Vortex Atom, The: A New Paradigm by Barry R Clarke Pdf

With clear illustrations throughout and without recourse to quantum mechanics, the reader is invited to revisit unsolved problems lying at the foundations of theoretical physics. Maxwell and his contemporaries abandoned their search for a geometrical representation of the electric and magnetic fields. The wave-particle dilemma and Bose-Einstein statistical counting have resulted in unsatisfactory non-realistic interpretations. Furthermore, a simple structure of the hydrogen atom that includes hyperfine levels is still wanting.Working with the latest experimental data in photonics a proposed solution to the wave-particle dilemma is suggested based on an array of circular-polarized rays. The Bose-Einstein counting procedure is recast in terms of distinguishable elements. Finally, a vortex model of a 'particle' is developed based on a trapped photon. This consists of a single ray revolving around a toroidal surface, and allows a geometrical definition of mass, electric potential, and magnetic momentum. With the adjustment of two parameters, values to 4 dp for the hyperfine frequencies (MHz) of hydrogen can be obtained for which a computer program is available.

Progress in Atomic Spectroscopy by W. Hanle Pdf

H. J. BEYER AND H. KLEINPOPPEN During the preparation of Parts A and B of Progress in Atomic Spectros copy a few years ago, it soon became obvious that a comprehensive review and description of this field of modern atomic physics could not be achieved within the limitations of a two-volume book. While it was possible to include a large variety of spectroscopic methods, inevitably some fields had to be cut short or left out altogether. Other fields have developed so rapidly that they demand full cover in an additional volume. One of the major problems, already encountered during the prepar ation of the first volumes, was to keep track of new developments and approaches which result in spectroscopic data. We have to look far beyond the area of traditional atomic spectroscopy since methods of atomic and ion collision physics, nuclear physics, and even particle physics all make important contributions to our knowledge of the static and dynamical state of atoms and ions, and thereby greatly add to the continuing fascination of a field of research which has given us so much fundamental knowledge since the middle of the last century. In this volume, we have tried to strike a balance between contribu tions belonging to the more established fields of atomic structure and spectroscopy and those fields where atomic spectroscopy overlaps with other areas.
