Introduction: Detecting paramagnetic contrast agent in vivo can be used in many applications such as cell tracking. Traditional T2-weighted sequence generates a signal loss appearing as a dark spot, referred to as negative contrast, at the site of paramagnetic contrast agent. Recently, there have been many efforts [1,2] to generate a positive contrast image by modifying pulse sequences. Liu et ...

Several reliable multicast schemes using router assistance have been proposed recently, which not only promise performance gains, but also simplify applications. Since they require network assistance, the effectiveness of such schemes degrades if the deployment of the required network services is sparse, meaning that an effective deployment strategy is critical. In this paper we study the perfo...

In this paper we present the Persistent Grid Mapping (PGM), a novel framework for interactive terrain rendering that provides a screen-uniform tessellation of terrains in a view-dependent manner. The persistent grid, which covers the entire screen, is triangulated with respect to the rendering capabilities of the graphics hardware and cached in video memory. The GPU maps each vertex of the pers...

A cDNA clone encoding the mRNA for the highly polymorphic human enzyme phosphoglucomutase 1 (PGM1; EC 5.4.2.2) has been isolated and characterized. This was achieved indirectly by first isolating a rabbit cDNA from an expression library using anti-rabbit PGM antibodies. A comparison of the nucleotide sequences shows that the homologies between human and rabbit PGM1 mRNAs are 92% and 97% for the...

The pattern of genetic differentiation among experimental populations of the flour beetle Tribolium castaneum suggested the hypothesis that relative fitness of three genotypes at the PGM-1 locus (or other linked loci) depends directly on diet. This hypothesis was tested by measuring several fitness components (developmental time, survival, fecundity, rate of egg cannibalism) on groups of indivi...

If benign cystic teratomas (dermoid cysts) of the ovary arise from a germ cell that has undergone meiosis, they should be missing genes which are present in the person. Three independently segregating allelic isozymes in 11 benign cystic teratomas of the human female ovary were compared with normal tissue of the same case. Dermoid cysts from persons heterozygous for these isozymes are frequentl...

Scene object recognition is an essential requirement for intelligent mobile robots. In addition to geometric or appearance features, modern recognition systems strive to incorporate contextual information, normally modelled through Probabilistic Graphical Models (PGMs) or Semantic Knowledge (SK). However, these approaches, separately, show some weaknesses that limit their application, e.g., the...

We compare several instances of pure-state Belavkin weighted square-root measurements from the standpoint of minimum-error discrimination of quantum states. The quadratically weighted measurement is proven superior to the so-called “pretty good measurement” (PGM) in a number of respects: 1. Holevo’s quadratic weighting unconditionally outperforms the PGM in the case of twostate ensembles, with ...

Color confinement by the mechanism of Kugo and Ojima can treat confinement of any quantized color carrying fields including dynamical quarks. However, the non-perturbative condition for this confinement has been known to be satisfied only in the pure-gauge model (PGM), which is a topological model without physical degrees of freedom. Here we analyze the Yang-Mills theory by adding physical degr...

Protocol analysis involve several parameters in model specification, for instance, transmission delay or the length of the transmitting window. Verification of the model with parameters is semi-decision process that depends on number of clocks, parameters and counters in the model. Using combination of different verification tools for timed models as HyTech, TReX and Uppaal we are able to find ...
