Mikio Tohyamad cell (RBC) production involving negative feedback factors are not understood. Evidence that RBC mass has a regulating effect on erythropoiesis can be given by the use of methemoglobinized erythrocytes. and by the studies on nephrectomized humans, in which a transfusion of erythrocytes caused a dep

Periodic Behaviour and Chaos in the Mechanism of Intercellular Communication Governing Aggregationcenters in the form of pulses, with a periodicity of several minutes. Relay of the cAMP signals by chemotactically responding cells allows one center to control the aggregation of up to 10. amoebae. We analyse a model for the cAMP signalling system, based on the activation of cAMP synthesis upon bi

The Environment of OJ 287: Nearby Galaxies and a Long Optical Jet?clear trigger mechanism for these jets. One possibility is the close interaction between the BL Lac host and the closeby galaxies (e.g. Heckman et al. 1986). This interaction has been seen many times in the case of quasars (Hutchings et al. 1989) but not so much is known about the close surroundings

Determinants of Country Economic Risks development model. A prime failure of the Arab world, as exposed by the events of the “Arab Spring,” is that the region has been unable to develop a viable private sector that is independent, competitive (not primarily reliant on government contracts and projects), and which is integrated with global markets.

Social Link Prediction Based on the Users’ Information Transfermeasure with a predictive interpretation that directly quantifies the strength of the effect of one user’s content on another’s. Experimental results show that content transfer combined with topology is more consistent with the real social network, which has better performance in link prediction.
