In the recent years we have seen a lot of activity around systems and experiments, like DIS at HERA or the heavy-ion experiments at RHIC, involving a large number of partons due to the high enery and/or the high number of participants of those experiments. The main problem in this regime is that of the high parton densities. In fact, in most of the models of multiparticle production, two contri...

Laser-based diagnostic methods are being applied to more and more flows of theoretical and practical interest and are revealing interesting new flow features. Imaging particles or droplets in Nephelometry and Laser Sheet Dropsizing methods requires a tradeoff between maximised signal to noise ratio, without over-saturating the detector. Droplet imaging results in lognormal pdf (probability dens...

In the inferior temporal (IT) cortex of monkeys, which has been shown to play a critical role in colour discrimination, there are neurons sensitive to a narrow range of hues and saturation. By contrast, neurons in the retina and the parvocellular layer of the lateral geniculate nucleus (pLGN) encode colours in a way that does not provide explicit representation of hue or saturation, and the pro...

Spontaneous neoplastic transformation develops within days in the NIH 3T3 line of cells through differential inhibition of their proliferation under contact inhibition. A small fraction of the population continues to multiply after saturation density is reached and is selected to progressively increase saturation density in successive rounds of confluence. The degree of selection at confluence ...
