In this paper, we propose a method for detection of glottal closure instants (GCI) in the voiced regions of speech signals. The method is based on periodicity of significant excitations of the vocal tract system. The key idea is the computation of coherent covariance sequence, which overcomes the effect of dynamic range of the excitation source signal, while preserving the locations of signific...

Diffusion Tensor Imaging (DTI) is a non-invasive imaging technique that allows estimation of the location of white matter tracts in-vivo, based on the measurement of water diffusion properties. For each voxel, a second-order tensor can be calculated by using diffusion-weighted sequences (DWI) that are sensitive to the random motion of water molecules. Given at least 6 diffusion-weighted images ...

Complex decision-making is a prominent aspect of requirements engineering (RE) and the need for improved decision support for RE decision-makers has been identified by a number of authors in the research literature. The fundamental viewpoint that permeates this thesis is that RE decision-making can be substantially improved by RE decision support systems (REDSS) based on the actual needs of RE ...

The paper aims to explore a conceptual framework in which improvement on waqf management may be made focusing on its relationship with beneficiaries. The study uses accountability as the main theoretical lens informing this, where waqf management does not merely see beneficiaries as the passenger in the relationship, rather, as one of the means to improve waqf management. Drawing from NGO accou...

In 2007 the Netherlands Pharmacovigilance Centre Lareb sent an signal to the Medicines Evaluation Board (MEB) concerning four reports of cutaneous vasculitis associated with nitrofurantoin [1]. These reports were received by Lareb in the period from September 1997 to October 2006. Since then, Lareb received three additional reports of vasculitis associated with the use of nitrofurantoin. The cu...

This paper presents a novel approach for improved diffusion tensor fibre tractography, aiming to tackle a number of the limitations of current fibre tracking algorithms, and describes a quantitative analysis tool for probabilistic tracking algorithms. We consider the sampled random paths generated by a probabilistic tractography algorithm from a seed point as a set of curves, and develop a stat...

TO THE EDITOR: The authors propose an interesting and reasonable model for the hypoxic dose (as kilometer hours) for the altitude training considering current relevant literatures (3). However, the totality of the response has been fitted with the percentage increase in hemoglobin mass production. In reality, the physiological responses of high performance athletes might be difficult to fit in ...

A test-tube baby [4] is the product of a successful human reproduction that results from methods beyond sexual intercourse [5] between a man and a woman and instead utilizes medical intervention that manipulates both the egg [6] and sperm [7] cells for successful fertilization [8]. The term was originally used to refer to the babies born from the earliest applications of artificial insemination...

To better understand the dynamic behavior of metabolic networks in a wide variety of conditions, the field of Systems Biology has increased its interest in the use of kinetic models. The different databases, available these days, do not contain enough data regarding this topic. Given that a significant part of the relevant information for the development of such models is still wide spread in t...

Whereas the capability of DNA uptake has been well established for numerous species and strains of bacteria grown in vitro, the broader distribution of natural transformability within bacterial communities remains largely unexplored. Here, we investigate the ability of bacterial isolates from the gut of grass grub larvae (Costelytra zealandica (White); Coleoptera: Scarabaeidae) to develop natur...
