Subject to the assumption that sub-barrier fusion is described by an effective one-dimensional energy-independent local potential barrier, the Jeffreys-Wentzel-Kramers-Brillouin approximation for the fusion cross sections is inverted to determine this effective potential. Potential barriers, with their associated experimental errors, are presented for 13C+ 13C and 40Ca+ 40Ca, and the assumption...

Caligus mortis Kensley, 1970 was originally described from females collected from intertidal pools along the coast of Namibia. During surveys at Jeffreys Bay and De Hoop Nature Reserve in South Africa, both females and males of C. mortis were collected from intertidal pool fish hosts. Based on this material a full description of the male is given, and a comparison with the female reveals the se...

The Yule–Simon distribution is usually employed in the analysis of frequency data. As the Bayesian literature, so far, ignored this distribution, here we show the derivation of two objective priors for the parameter of the Yule–Simon distribution. In particular, we discuss the Jeffreys prior and a loss-based prior, which has recently appeared in the literature. We illustrate the performance of ...

The instability, rupture, and subsequent growth of holes in a thin Jeffreys-type viscoelastic film under the influence of long-range van der Waals force are investigated using both linear stability analysis and nonlinear numerical solutions. The linear stability analysis of full governing equations valid for arbitrary wave numbers shows that although fluid rheology does not influence the domina...

The Minimum Description Length (MDL) approach to parametric model selection chooses a model that provides the shortest codelength for data, while the Bayesian approach selects the model that yields the highest likelihood for the data. In this article I describe how the Bayesian approach yields essentially the same model selection criterion as MDL provided one chooses a Jeffreys prior for the pa...

The discovery of an anonymous multiallelic locus in 1980 demonstrated for the first time that the human DNA contains hypervariable regions (Wyman & White, 1980). Eight alleles of a polymorphic locus that was not associated with any known gene were identified during the blot hybridization of total human genomic DNA treated with the restrictase EcoRI with a human DNA fragment (16 tbp in length) i...

We investigate shrinkage priors on power spectral densities for complex-valued circular-symmetric autoregressive processes. construct predictive densities, which asymptotically dominate (i) the Bayesian density based Jeffreys prior and (ii) estimative with maximum likelihood estimator, where Kullback-Leibler divergence from true to a is adopted as risk. Furthermore, we propose general construct...

Abstract. General theoretical principles that enable the derivation of prior probabilities are of interest both in practical data analysis and, more broadly, in the foundations of probability theory. In this paper, it is shown that the general rule for the assignment of priors proposed by Jeffreys can be obtained from, and is logically equivalent to, an intuitively reasonable information-theore...

In this paper, we use the Linex loss function to derive the Bayesian estimate of the parameter of the exponential distribution based on ranked set sampling (RSS). Under this setup, we use both conjugate and Jeffreys prior distributions. To assess the efficiency of the obtained estimates, we compute the bias and mean squared error of the derived estimates and compare them with those based on the...
