The subspace Hamiltonian technique, introduced several years ago, has proved convenient for determining bound states and resonances associated with surfaces and defects. Here we discuss the extension of this technique to other problems, including total-energy calculations and real-time computer simulations. %e prove several theorems and report numerical calculations that help to explain the use...

Many problems in mathematics and science require the use of infinite-dimensional spaces. Consequently, there is need for an analogue of the finite-dimensional notions of ‘Lebesgue almost every’ and ‘Lebesgue measure zero’ in the infinite-dimensional setting. The theory of prevalence addresses this need and provides a powerful framework for describing generic behavior in a probabilistic way. We ...

This study among 426 Japanese couples working in different occupational sectors tested the hypothesis that perspective taking moderates the crossover of work engagement. More specifically, we predicted that husbands' work engagement would cross over to their wives, particularly when wives scored high on perspective taking (the spontaneous tendency to adopt the psychological perspective of other...

NE of the fundamental problems concerning the mechanism of cross0 ing over is the question of chromatid interference. In the absence of chromatid interference the identity of the chromatids involved in two or more chiasmata or points of crossing over is random. Positive chromatid interference would exist if a crossover between one pair of chromatids reduced their chances of being involved in a ...

The number of selectively neutral polymorphic sites in a random sample of genes can be affected by ancestral selectively favored substitutions at linked loci. The degree to which this happens depends on when in the history of the sample the selected substitutions happen, the strength of selection and the amount of crossing over between the sampled locus and the loci at which the selected substi...

The high barriers to entry in the former elite telecom industry have been torn down, leaving a brutally competitive market, where over-the-top (OTT) providers like Vonage, Skype, Netflix and others, with no desire to own a network, provide offerings that ride on top of CSP networks.
