Crossed-field Microwave Devices, Volume II: Principal Types of Crossed-Field Devices, Analysis of Oscillator System Performance, Regional Progress and Trends focuses on the progress and state of the art crossed-field microwave devices in theory and practice. The selection first offers information on injection type tubes and voltage tuned oscillators. Discussions focus on the principle of the injection type traveling wave tubes, delay lines, resistive wall amplifier, space-charge effects, and grid control of magnetrons. The text then takes a look at mechanically tuned oscillators and wide band and externally stabilized tunable oscillators. The publication examines fixed frequency magnetron oscillators and phasing by RF signals. Topics include conventional pulsed rising-sun magnetrons, long anode magnetrons, inverted magnetrons, eccentricity of the cathode in magnetrons, mutual synchronization, and modulation using phased oscillators. Frequency pushing, loading effects, and frequency modulation are also discussed. The selection is a vital reference for readers interested in crossed-field microwave devices.

In most breeding programs of plant and animal species, genetic data (such as data from field progeny tests) are used to rank parents and help choose candidates for selection. In general, all selection processes first rank the candidates using some function of the observed data and then choose as the selected portion those candidates with the largest (or smallest) values of that function. To make maximum progress from selection, it is necessary to use a function of the data that results in the candidates being ranked as closely as possible to the true (but always unknown) ranking. Very often the observed data on various candidates are messy and unbalanced and this complicates the process of developing precise and accurate rankings. For example, for any given candidate, there may be data on that candidate and its siblings growing in several field tests of different ages. Also, there may be performance data on siblings, ancestors or other relatives from greenhouse, laboratory or other field tests. In addition, data on different candidates may differ drastically in terms of quality and quantity available and may come from varied relatives. Genetic improvement programs which make most effective use of these varied, messy, unbalanced and ancestral data will maximize progress from all stages of selection. In this regard, there are two analytical techniques, best linear prediction (BLP) and best linear unbiased prediction (BLUP), which are quite well-suited to predicting genetic values from a wide variety of sources, ages, qualities and quantities of data.

Smart. Funny. Fearless."It's pretty safe to say that Spy was the most influential magazine of the 1980s. It might have remade New York's cultural landscape; it definitely changed the whole tone of magazine journalism. It was cruel, brilliant, beautifully written and perfectly designed, and feared by all. There's no magazine I know of that's so continually referenced, held up as a benchmark, and whose demise is so lamented" --Dave Eggers. "It's a piece of garbage" --Donald Trump.

This book covers a new explanation of the origin of Hamiltonian chaos and its quantitative characterization. The author focuses on two main areas: Riemannian formulation of Hamiltonian dynamics, providing an original viewpoint about the relationship between geodesic instability and curvature properties of the mechanical manifolds; and a topological theory of thermodynamic phase transitions, relating topology changes of microscopic configuration space with the generation of singularities of thermodynamic observables. The book contains numerous illustrations throughout and it will interest both mathematicians and physicists.
