We developed an empirical Bayes procedure to estimate genetic distances between populations using allele frequencies. This procedure makes it possible to describe the skewness of the genetic distance while taking full account of the uncertainty of the sample allele frequencies. Dirichlet priors of the allele frequencies are specified, and the posterior(More)
A model for interval mapping of quantitative trait loci (QTLs) in an F2 population using genetic markers such as restriction fragment length polymorphisms (RFLPs) is proposed. Based on this model the log-likelihood ratio statistic is divided into two useful statistics which can be used to detect additive and dominance effects of QTLs, separately. The(More)
—This paper describes control of distance attenuation using spherical loudspeaker array. Fisher et al. proposed radial filtering with spherical microphone to control the sensitivity to distance from a sound source by modeling the propagation of waves in spherical harmonic domain. Since transfer functions are not changed by swapping their inputs and outputs,(More)
With certain conditions for target-samples and beams, we have identified specific particles (e.g., 4.75MeV tritons and 3 He-particles, and 15.9 MeV deuterons) from 3D fusion reactions with yield ratios [3D]/[2D] on the order of 1E-4 to 1E-3, in contrary to the calculated [3D]/[2D] yield ratio of 1E-30 according to conventional random nuclear reaction theory(More)
