The book provides a unifying insight into fluctuation phenomena in a broad variety of vibrational systems of current interest. It consists of individual chapters written by leading experts in the field. The chapters are self-contained and complement each other. The ongoing rapid development of well-characterized mesoscopic vibrational systems has made it possible to address fundamental physics problems and to explore new approaches to quantum and classical measurements, with applications to quantum information, condensed matter physics, and engineering. The book gives an account of major results in this direction. The topics include dynamics and quantum control of microcavity modes coupled to qubits, measurements with bifurcation-based amplifiers and new types of such amplifiers; switching rate scaling and new quantum mechanisms of metastable decay; wave mixing and parametric excitation in the quantum regime; collective phenomena and the interaction-induced discrete time symmetry breaking; and back-action and shot noise in electron-vibrational systems.

The ocean is transparent to sound where slight irregularities within the ocean cause sound fluctuations, and thus set limits on the many uses of sound in the ocean, similar to the limits imposed by the atmosphere on ground-based telescopes. This 1979 book attempts to connect the known structure of the ocean volume with experimental results in long-range sound transmission. Theories of wave propagation through irregular media, developed for optical and radio wave transmission are found to be inapplicable in many respects due to the complications of ocean structure, particularly the combination of anisotropy and 'sound channel'. The authors extend wave propagation theory to account for the ocean complications and introduces the path-integral approach to the solution of the strong-scattering regime that solves many long-standing problems. The book is written at the post-graduate level, but has been carefully organised to give experimenters a grasp of important results without undue mathematics.

It uses Boveda's advanced technology to either add or deplete moisture as needed, maintaining the ideal humidity level of 45%-55% RH inside your instrument case. This ensures your guitar remains in peak playing condition, safeguarding the wood and strings from damage caused by dryness or excessive moisture.Please note, the Humidipak system is designed for maintaining and restoring instrument humidity. It's not intended for dehumidification in high humidity environments. If your instrument hasn't been previously humidified or is in a known dry condition, it's recommended to use Humidipak Restore to safely reestablish the proper humidity level to your instrument and its case before using the Humidipak Maintain System. Remember, your guitar still thinks it's a tree. Hydrate it. With the D'Addario Humidipak Maintain Replacement Two-Way Humidity Control System, maintaining your instrument's health has never been easier or more reliable.
