The non-destructive Meyer method was evaluated to determine the bark volume of beech (Fagus orientalis Lipsky) stands in north of Iran. The sample size was 185 standing trees collected from 4 geographical aspects (north, south, west and east) aspects. The constant k values and bark thickness (2e mm) of 185 standing trees were used to calculate the bark volume by the Meyer method. In this study,...

Examination of the recent literature on the question of when to use one-tailed tests of significance in psychological research reveals a state of unresolved disagreement. A variety of differing opinions (1, 2, 5, 7, 8, 9, 10, pp. 62-63) have been presented, ranging from Burke's (2) exhortation that psychologists should never report one-tailed tests in the public literature to Jones' (8) stateme...

To improve the reliability of statistically significant test results between two imaging systems in receiver operating characteristic (ROC) analysis, it was important to evaluate the variances among readers. In this study, we tested statistically significant differences with actual experimental data from ROC studies that were performed to evaluate the detectability of 4 kinds of image intensifi...

Motivated by recent studies in financial mathematics and other areas, we investigate the exponential functional Z = ∫∞ 0 e−X(t)dt of a Lévy process X(t), t ≥ 0. In particular, we investigate its tail asymptotics. It is shown that, depending on the right tail of X(1), the tail behavior of Z is exponential, Pareto, or extremely heavy-tailed.

Campylobacter corcagiensis CIT045(T) (=CCUG 64942(T), LMG 27932(T)), a new member of the Campylobacter genus, has recently been isolated from lion-tailed macaques in Cork, Ireland. To further characterize this new species and its potential pathogenicity, the genome sequence of C. corcagiensis was determined and is presented here.

Black-tailed prairie dog (Cynomys ludovicianus) colonies can become overcrowded, and the colonies, landscape, and people affected by them may benefi t from controlled populations. Contraception is a method that may be useful, particularly where lethal control is inappropriate or illegal. We investigated if oral administration of 20,25-diazacholesterol (DiazaCon®), an inhibitor of cholesterol an...

In this paper, we compute doubly truncated moments for the selection elliptical class of distributions, including some multivariate asymmetric versions well-known such as normal, Student’s t, slash, among others. We address members family, establishing neat formulation high-order and its first two moments. establish sufficient necessary conditions existence these Further, propose optimized meth...

Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for s...
