We investigate the support of a capacity-achieving input to vector-valued Gaussian noise channel. The is subjected radial even-moment constraint and either allowed take any value in Rn or restricted given compact subset Rn. It shown that distribution composed countable union submanifolds, each with dimension n−1 less. When Rn, this finite. Finally, have Lebesgue measure 0 be nowhere dense

in this article, we will estimate efficiency amountof decision-making unit by offering the continuous piecewise polynomialextrapolation and interpolation by ccr model input-oriented on the assumptionthat it is constant returns to scale in different times. and finally, we willestimate efficiency amount of decision-making unit indifferent times byoffering an example.

Using single-beam, oscillating optical tweezers we can trap and rotate rodshaped bacterial cells with respect to the optical axis. This technique allows imaging fluorescently labeled three-dimensional sub-cellular structures from different, optimized viewpoints. To illustrate our method we measure D, the radial width of the Z-ring in unconstricted Escherichia coli. We use cells that express Fts...

One of the major problems in Data Envelopment Analysis (DEA) is to determine the projection of inefficient Decision Making Units (DMUs) into the efficient frontier. In conventional DEA models, inputs and outputs of inefficient DMUs alter arbitrarily for reaching to the efficient frontier. Nevertheless, sometimes the ability of DMUs is defined and restricted. Moreover, there are situations in th...

INTRODUCTION Efficiency analysis is necessary in order to avoid waste of materials, energy, effort, money, and time during scientific research. Therefore, analyzing efficiency of knowledge production in health areas is necessary, especially for developing and in-transition countries. As the first step in this field, the aim of this study was the analysis of selected health research center effic...

Luminance gratings reportedly produce a stronger functional magnetic resonance imaging (fMRI) blood oxygen level-dependent (BOLD) signal in those parts of the retinotopic cortical maps where they are oriented radially to the point of fixation. We sought to extend this finding by examining anisotropies in the response of cortical areas V1-V3 to motion-defined contour stimuli. fMRI at 3 Tesla was...

It has been shown that the sensitivity and accuracy of orientation perception in the periphery is significantly better when the orientations are radial with respect to the fixation point than when they are tangential. However, since perception and action may be dissociated, it is unclear whether the perceptual radial effect has a counterpart in reaction time (RT) of motor responses. Furthermore...

Aspect-oriented approaches have recently been proposed to address the problem of specifying dynamic object-based systems, by depicting the various roles of the objects separately. In this paper, we consider an approach based on the observable behavior of objects and propose a specification formalism for reusable object interfaces with input/output-driven assumption-guarantee predicates. The for...

One fundamental issue in service-oriented computing concerns the question whether services can be composed in a manner that allows them to achieve their individual goals. In this paper we use a variant of interface automata as an abstraction of the input/output behaviour of services, which are themselves represented as terms in the π-calculus extended with an action for expressing service colla...

This research identifies returns to scale (RTS) of efficient decision making units (DMUs) with desirable (good) and undesirable (bad) inputs and outputs by presenting a new DEA (data envelopment analysis) approach. In this study, we first introduce a new input-output oriented model to determine efficient DMUs in the presence of undesirable factors and then, returns to scale of these DMUs are es...
