Attenuated correlation

Variations in DOC quality (DOC - specific attenuation and absorption) warrant further discussion. These variations can be divided into two related categories changes in specific attenuation correlated with DOC concentrations, and changes in specific attenuation correlated with lake and watershed characteristics. The immediate basis for the power relationships between K io [DOC] (Table 3) comes directly from the power relationship between ad32o and [DOC] (Table 2) for the data of Morris et al. [60]. But why should DOC quality change together with DOC concentration over the scale of lakes in this study What determines the exponent in the power model relating specific absorption and DOC concentration ... 

Entanglement transfer experiment in NMR quantum information processing - This paper of 2002 by Boulant and co-workers [18] describes an experiment of entanglement transfer by NMR. The aim is to transfer an entangled state of a pair of qubits to another pair of qubits, a process which was first demonstrated using photons in 1998, by Pan and collaborators. The authors used the four nuclei of crotonic acid as qubits. The process was followed by quantum state tomography and the efficacy of the experiment was quantified by a measured called attenuated correlation. A value of 0.65 for this measure at the end of the protocol, indicated that the pseudo-entangled state was indeed transferred from one pair of qubits to the other. 

The frequency correlation lowers environmental disturbances. The correlation provides an output proportional to the content of Aa at the reference signal fundamental frequency, the phase conelation gives the sign of Aa. Where the stress gradients are very steep in materials of high thermal conductivity being loaded at low frequencies, the SPATE signals are attenuated and a correction factor has to be introduced to take into account this effect. 

At CSM Materialteknik AB the question has been raised whether the porosity estimation can be simplified further by utilizing attenuation measurements at a single frequency only. Empirical work show that for a given frequency, which is selcted based on the thickness of the inspected object, there is a correlation between the attenuation and the porosity contents. However, there has still not been any documented results proving that single frequency measurements are sufficient for porosity estimation. 

In Figure 4 the measured attenuation values (TT) and the corresponding estimates are plotted against each other. Ideally (with error free estimates) all sample points should lie on the straight line through the origin with unit slope. Clearly there is a strong correlation between the estimates and the true values. 

It would also be of interest to investigate if the attenuation estimates can be further improved by extending our input data vectors. Since attenuation (and porosity) is spatially correlated, we should expect improvements when including data from A-.scans in a neighbourhood around the point of interest. This is also a topic for future work. 

There was thus the need for optical experiments showing the flaws of classical electrodynamics. An important difference between a wave and a particle is with respect to a beam splitter a wave can be split in two while a photon can not. An intensity correlation measurement between the two output ports of the beamsplitter is a good test as a wave would give a non zero correlation while a particle would show no correlation, the particle going either in one arm or the other. However, when one takes an attenuated source, such as the one used by Taylor, it contains single photon pulses but also a (small) fraction of two... 

Since the Lindemann ratio dija 0.1 is empirically roughly the same for all substances, one expects the g value, as measured by sound attenuation, to be correlated with the glass transition temperature. Note that this relationship is independent of the details of the bead assignment. Equation (20), if rewritten as Tg di/a) g, is almost obvious, given the interaction of the form in Eq. (17) The typical lattice displacement, at Tg, is roughly A< ) j- dija. On the other hand, the typical structural excitations have the energy of about Tg, at the glass transition.

Allopurinol has been shown to attenuate lipid peroxidation in ethanol-fed rats (Kato etal., 1990). However, this was not correlated with any possible effect on histological damage and, as discussed previously, the significance of lipid peroxidation is unclear. Despite the evidence suggesting that oxidative stress and increased oxidative metabolism may play a role in the pathogenesis of human alcoholic liver disease, it remains to be shown that treatment with specific antioxidants will modify this process.

Unavoidably, the efficiency of the different low-pass J filters in removing direct correlations induces attenuation of the signals associated with long-range couplings. For some molecules, the choice of the most suitable low-pass J filter may be first determined by the attenuation of those signals. Neglecting relaxation, pulse imperfections and offset effects, the... 

In the wetlands of Idaho, the formation of an Fe(III) precipitate (plaque) on the surface of aquatic plant roots (Typha latifolia, cat tail and Phalaris arundinacea, reed canary grass) may provide a means of attenuation and external exclusion of metals and trace elements (Hansel et al, 2002). Iron oxides were predominantly ferrihydrite with lesser amounts of goethite and minor levels of siderite and lepidocrocite. Both spatial and temporal correlations between As and Fe on the root surfaces were observed and arsenic existed as arsenate-iron hydroxide complexes (82%). 

The General Series Expansion for Stacks. In practice, ID scattering intensities can always be modeled by programming the obvious series expansion of such a structural entity every correlated distance along the stack axis is producing an attenuated oscillation according to Hk (5) that is weighted by the probability of its occurrence under consideration of the zero-sum rule and the related correlation-construction principle (p. 158, Fig. 8.30)...
