INTRODUCTION. Balanced SSFP has the unusual property that the signal is sensitive to resonance frequency. Considering only T1, T2 and diffusion effects, this dependence is predicted to be symmetric with respect to the experimental center frequency (Fig. 3a, “theory”). However, we recently demonstrated that the signal measured in vivo is asymmetric (Fig. 3a, points) [1]. For a region-of-interest...

In this paper, a novel non-parametric based glottal closure instant (GCI) detection method after filtering the speech signal through a pulse shaping filter is proposed. The pulse shaping filter essentially de-emphasises the vocal tract resonances by emphasising the frequency components containing the pitch information. The filtered signal is subjected to non-linear processing to emphasise the G...

For early diagnosis of malignancies in the gastrointestinal tract, surveillance endoscopy is increasingly used to monitor abnormal tissue changes in serial examinations of the same patient. Despite successes with optical biopsy for in vivo and in situ tissue characterisation, biopsy retargeting for serial examinations is challenging because tissue may change in appearance between examinations. ...

Mechanisms contributing to the spread of avian influenza seem to be well identified, but how their interplay led to the current worldwide spread pattern of H5N1 influenza is still unknown due to the lack of effective global surveillance and relevant data. Here we develop some deterministic models based on the transmission cycle and modes of H5N1 and focusing on the interaction among poultry, wi...

This paper reviews the combinations of control and preventive measures applied in poultry for avian influenza and the reasons why the measures have been recommended and/or applied, taking into account local epidemiological situations, field observations and other scientific information that provide justification for the measures introduced. It highlights areas where gaps in knowledge exist and ...

Very Low Frequency (VLF) tests are often used for after-laying tests of power cables since the reactive power demand is much lower at VLF than at 50 Hz. In order to augment the usefulness of the test, it is often complemented by a measurement of dielectric dissipation factor (tan ), where the acceptance of the tested object is based on this measurement. A traceability chain for dissipation fac...

translation is an indispensable tool for communication between the diverse linguistic groups. it opens new horizons for the people living in a country so that it makes changes and improvements in their society, especially in the literature. through the translation process, some literary principles and elements are introduced into the home literature which did not exist before. these features em...

An econometric model is specified in which an individual’s income and the income mix of the neighbourhood in which the individual resides are endogenous, thus providing a holistic model of phenomena that previously have been fragmented into neighbourhood effects and neighbourhood selection literatures. To overcome the biases from selection and endogeneity, the parameters of this model are estim...

Drug absorption, distribution, metabolism and excretion (ADME) often involve interaction of a drug with specific proteins. Knowledge about these ADME-associated proteins is important in facilitating the study of the molecular mechanism of disposition and individual response as well as therapeutic action of drugs. It is also useful in the development and testing of pharmacokinetics prediction to...
