In cooperative games, players have a possibility to form different coalitions. This leads the questions about ways motivate all collaborate, i.e. so-called grand coalition. One of such is captured by concept nucleolus, which dates back Babylonian Talmud. Weighted voting games class that are often used model decision making processes in parliaments. this paper, we provide an algorithm for comput...

The activation of the nucleolus of primary root cells of Sinapis alba embryos during the first 72 h of germination was monitored by autoradiographic, ultrastructural and microstereological methods. Autoradiographs showed that within 48 h, the nucleolus progressively resumed the capacity to synthesize pre-rRNA molecules at a high rate. In quiescent embryos the nucleolus was small, compact and co...

objective: breast cancer comprise approximately one third of malignant cases in women and is considered as the most common invasive condition in women at an age range of 15-54 years and as the second most prevalent cause of mortality at an age range of 55-74 years. tumor inhibiting factor p53 is a vital homeostatic regulator and its inactivation at the related gene or molecule could lead to tum...

Mitosis in the amebo-flagellate Naegleria pringsheimi is acentrosomal and closed (the nuclear membrane does not break down). The large central nucleolus, which occupies about 20% of the nuclear volume, persists throughout the cell cycle. At mitosis, the nucleolus divides and moves to the poles in association with the chromosomes. The structure of the mitotic spindle and its relationship to the ...

A commonly held belief of game theorists is that the pre-nucleolus of the modest bankruptcy game is identical to the pre-nucleolus of its dual game, the greedy bankruptcy game. In this paper we provide some results that indicate that this belief is false. We establish some non-coincidence results of the pre-kernel and pre-nucleolus of the modest bankruptcy game with respect to the pre-kernel an...

Regions of highly repetitive DNA, such as those found in the nucleolus, show a self-organization that is marked by spatial segregation and frequent self-interaction. The mechanisms that underlie the sequestration of these sub-domains are largely unknown. Using a stochastic, bead-spring representation of chromatin in budding yeast, we find enrichment of protein-mediated, dynamic chromosomal cros...

for periods of 15 to 60 min resulted in disappearance of nucleolar DNA and diffusion of nucleolinar material, as demonstrated by toluidine blue-molybdate, acid phosphatase, and lead staining throughout the nucleolus. Ultrastructural studies of the heated cells indicated that the fibrillar component of the nucleolus, like the nucleolini, became diffusely distributed throughout the nucleolus and ...
