Evidence that Brm1 is crucial for the formation of this repressive complex includes emergence of Brm1/RB/C/EBPα complexes in nuclear proteins from young livers after incubation with excess Brm1, and reduction of Brm1 levels from RB/C/EBPα complexes in old livers after heterochronic parabiosis (Conboy et al., 2005).
Such feedback mechanisms represent a characteristic feature of complex adaptive systems which facilitates the emergence of complex patterns of behaviors such as homeostasis and stable states (reference: Complex Adaptive Systems Modeling: A multidisciplinary Roadmap).
The surface chemistries of this technique have become quite complex with the emergence of the sub 22 nm technology nodes.
In KwaZulu, the old battle between the Zulu-nationalist Inkatha party and the ANC has grown more complex with the emergence of the United Democratic Movement (UDM), a party of breakaways in which Mr Nkabinde was the regional boss.
But in 2014, the Syrian civil war became even more complex with the emergence of the Islamic State, an extremist movement that has since seized a large chunk of northern Syria, including Raqqa, the capital of its caliphate, as well as Deir ez-Zor, Syria's seventh-largest city, and other strategic areas.
Networks of inter-personal communication have grown larger and more complex with the emergence of digital technologies [1].
The debate is becoming more complex with the emergence of this new putative SAR (stramenopiles/alveolata/rhizaria) supergroup, as proposed by Burki [ 23].
Donald Brownlee and palaeontologist Peter Ward expanded upon the concept of a galactic habitable zone, as well as the other factors required for the emergence of complex life, in their 2000 book Rare Earth: Why Complex Life is Uncommon in the Universe.
Thus, our work may suggest that other mechanisms, different from both adaptation to complex environments and from accumulation of frozen accidents, also play a role in the emergence of complex systems.
