Simultaneous multi -s l ice (SMS) MRI has become a popular technique in both research and cl inical practice, as i t provides information about multiple sl ices at the time of a conventional s ingle-sl ice measurement. For technical reasons, SMS is commonly l imited to the acquisi tion of paral lel s l ices. Here, we propose a new Cartesian sequence for the simultaneous excitation of orthogonal...

A phantom network of Gaussian chains far from the point of gelation can be described as a gas of interacting particles represented by the cross links. The type of particles varies with the network functionality, whereas the type of interaction depends on the properties of the connecting chains. In a mean field approximation the Equation of State can be calculated using Mayer’s cluster expansion...

In our previous work[11] , a relation between Tsukiyama problem about self homotopy equivalence was found by using a generalization of phantom map. In this note , fundamental result is established for such a generalization. This is the first time one can deal with phantom maps to space not satisfying finite type condition. Application to Forgetful map is also discussed briefly.

The subjective attributes of 2-channel phantom images of transient piano, continuous trumpet and male speech sources were elicited using pair-wise comparison between reference mono images and their phantom images. The attributes elicited included ‘image focus’, ‘image width’, ‘image distance’, ‘brightness’, ‘hardness’ and ‘fullness’. The effect of interchannel time and intensity differences on ...

PURPOSE Breast density measurement has the potential to play an important role in individualized breast cancer risk assessment and prevention decisions. Routine evaluation of breast density will require the availability of a low-cost, nonionizing, three-dimensional (3-D) tomographic imaging modality that exploits a strong properties contrast between dense fibroglandular tissue and less dense ad...

We study the conditions of validity of the generalized second law in phantom dominated era. PACS: 98.80.-k, 98.80.Jk

We describe the possible scenarios for the evolution of a thin spherically symmetric self-gravitating phantom shell around the Schwarzschild black hole. The general equations describing the motion of the shell with a general form of equation of state are derived and analyzed. The different types of space-time R±and T±-regions and shell motion are classified depending on the parameters of the pr...

We consider the problem of describing the asymptotic behaviour of FRW universes near their spacetime singularities in general relativity. We find that the Bel-Robinson energy of these universes in conjunction with the Hubble expansion rate and the scale factor proves to be an appropriate measure leading to a complete classification of the possible singularities. We show how our scheme covers al...
