BACKGROUND The similarities between gametogenic and carcinogenesis processes have been noted for more than decades. Among prominent similarities between these two processes is expression of a group of antigens, namely cancer-testis antigens in both the testes and various cancer tissues. Outer dense fiber (ODF) proteins are testis-specific proteins localized to sperm tails and involved in sperm ...

The online discussion forum (ODF) is one of the most widely used e-learning tools in open distance learning (ODL) environments. A popular line of research focuses on producing instruments that can be used to assess the level and amount of learning that takes place via transcript analysis of ODF-discourse. Of current interest is the influential community of inquiry (CoI) theoretical framework, f...

Opportunistic Data Forwarding (ODF) has drawn much attention in mobile adhoc networking research in recent years. The effectiveness of ODF in MANET depends on a suitable routing protocol which provides a powerful source routing services. PLSR is featured by source routing, loop free and small routing overhead. The update messages in PLSR are integrated into a tree structure and no need to time ...

Independent component analysis (ICA) does not follow the superposition rule. This motivates us to study a negative event-related potential - mismatch negativity (MMN) estimated by the single-trial based ICA (sICA) and averaged trace based ICA (aICA), respectively. To sICA, an optimal digital filter (ODF) was used to remove low-frequency noise. As a result, this study demonstrates that the perfo...

BACKGROUND Retinal vein pulsation is often absent in glaucoma, but can be induced by applying a graded ophthalmodynamometric force (ODF) to the eye, which is elevated in glaucoma. AIM To assess whether ODF has a predictive value in determining glaucoma progression. METHODS 75 patients with glaucoma and suspected glaucoma were examined prospectively in 1996, and then re-examined at a mean of...

RÉSUMÉ. Le croisement de fibres est un problème important dans la plupart des algorithmes de suivi de fibres basés sur l’imagerie du tenseur de diffusion (DTI). Pour surmonter les limites du DTI, des techniques d’IRM à haute résolution angulaire (HARDI) comme l’imagerie par q-ball (QBI) ont été introduites. Le but de cet article est de présenter un état de l’art des techniques de reconstruction...

the fisher information matrix for a mixture of two pareto distributions is derived. numericaltabulations of the matrix are also provided for practical purposes. the work is motivated by a real-lifeexample.

a new derivation of the quantum boltzmann transport equation for the fermion system from the quantum time evolution equation for the wigner distribution function is presented. the method exhibits the origin of the time - irreversibility of the boltzmann equation. in the present work, the spin dependent and indistinguishibility of particles are also considered.

Introduction A great deal of recent research in diffusion MRI has focussed on improved modelling and reconstruction of multiple white matter fibre orientations within single image voxels. These methods are typically used to create an orientation distribution function (ODF) at each voxel, which represents the orientations of each fibre population crossing the voxel. However, very little attentio...
