In this paper, a regression type estimator representing a class of estimators is proposed to estimate the population mean of the study variable. The bias and mean square error of the proposed estimator are obtained. Also the optimizing value of the unknown parameter is derived and the expression of minimum mean square error is obtained. Further since the proposed estimator is biased, a jackknif...

BACKGROUND A recent drug interaction study reported that when azithromycin was administered with the combination of ivermectin and albendazole, there were modest increases in ivermectin pharmacokinetic parameters. Data from this study were reanalyzed to further explore this observation. A compartmental model was developed and 1,000 interaction studies were simulated to explore extreme high iver...

Properties of scalar–isoscalar mesons are analysed in an unitary model using separable interactions in three decay channels: ππ , KK and an effective 2π2π. We obtain different solutions by fitting various data on the ππ and KK phase shifts and inelasticities including the CERN-Cracow-Munich measurements of the πp↑ → π+π−n reaction on a polarized target. Analytical structure of the meson-meson m...

A central concern of linguistic theory is to account for how the arguments of a given lexical item are associated with positions in a syntactic structure. Many theorists hold that this mapping is mediated by a so-called thematic hierarchy. In Principles-and-Parameters style theories this typically works as follows. A verb selects arguments with certain thematic (θ-) roles. These θ−roles are ran...

A set of type-(m, n) S is a set of points of a design with the property that each block of the design meets either m points or n points of S. The notions of type and of parameters of a k-set (there called characters) were introduced for the first time by Tallini Scafati in [M. Tallini Scafati, {k, n}-archi di un piano grafico finito, con particolare riguardo a quelli con due caratteri. Note I a...

This paper presents a discussion of the susceptibility of human factors to the use of folk models. The case of automation-induced complacency is used as a guiding example to illustrate how folk models (1) substitute one label for another rather than decomposing a large construct into more measurable specifics; (2) are immune to falsification and so resist the most important scientific quality c...

This paper proposes a classification of three-revolute orthogonal manipulators that have at least one of their DH parameters equal to zero. This classification is based on the topology of their workspace. The workspace is characterized in a half-cross section by the singular curves. The workspace topology is defined by the number of cusps and nodes that appear on these singular curves. The mani...

The original CACTI tool was released in 1994 to give computer architects a fast tool to model SRAM caches. It has been widely adopted and used since. Two new versions were released to add area and active power modeling to CACTI. This new version adds a model for leakage power and updates the basic circuit structure and device parameters to better reflect the advances in scaling semiconductors w...

We study string propagation in a spacetime with positive cosmological constant, which includes a circle whose radius approaches a finite value as |t| → ∞, and goes to zero at t = 0. Near this cosmological singularity, the spacetime looks like IR/ZZ. In string theory, this spacetime must be extended by including four additional regions, two of which are compact. The other two introduce new asymp...
