African narratives in the West, they proliferate.

There is a forceful logic which emphasizes that if something does not exist, it cannot possibly proliferate.

Our models show that in the absence of therapy, cancer cells that haven t evolved resistance will proliferate at the expense of the less fit resistant cells. When a large number of sensitive cells are killed, say, by aggressive therapies, resistant types can proliferate unconstrained.

We began to counter proliferate, and we dropped the number of nuclear warheads in the world to about a total of 21,000.

And a pig disease, a pig virus, and a human virus can both proliferate, and because of their kind of reproduction, they can combine and produce a new virus.

The global financial crisis occurred because we ignored externalities shadow prices and institutions allowing instability and inequality to proliferate. Building a more stable, sustainable future requires getting policies, prices, and incentives right.

We take them from nature, and the only thing that we do, we give them the optimal conditions, under the greenhouses or in the climate rooms, in order to proliferate, multiply and reproduce.

Some forms of crime proliferate across borders transnational organized crime, terrorism, drug trafficking and trafficking in persons are examples of such problems. National efforts alone are not enough to deal with such crime.

Mexico stresses that the best way to deal with the danger posed by weapons of mass destruction is to work towards their complete and irreversible elimination, bearing in mind that, in principle, what does not exist cannot proliferate.

Ri Yong Ho told the world body's annual General Assembly that North Korea had taken significant goodwill measures in the past year, such as stopping nuclear and missiles tests, dismantling the nuclear test site, and pledging not to proliferate nuclear weapons and nuclear technology.

Beyond semantics lies the more consequential, but equally ambiguous, question of the international community s role and responsibility. Just as too broad a definition could undermine a country s sovereignty, too narrow a definition like that which seems to predominate today allows violence and instability to proliferate.

WASHINGTON, DC The year 2015 was difficult, punctuated by declining growth forecasts, horrific terror attacks, massive refugee flows, and serious political challenges, with populism on the rise in many countries. In the Middle East, in particular, chaos and violence has continued to proliferate, with devastating consequences.

As a party to the main international non proliferation instruments, our country whose neutral status involves such important obligations such as not to produce, deploy or proliferate weapons of mass destruction fully supports the efforts of the international community in this area and participates in their implementation.

Although resistant forms are commonly found in tumors that haven t yet been exposed to treatment, they generally occur in small numbers. This suggests that resistant cells are not so unfit that drug sensitive cells completely out competed them, but that they struggle to proliferate when both types are present.

They will likely follow suit, and the more weapons proliferate in the volatile Middle East, the more likely it is that accidents and miscalculations could lead to their use. Moreover, there are genuine fears that rogue elements in a divided Iranian government might leak weapons technology to terrorist groups.

So, while powerful, hegemonic countries like the US managed to impose their own rules on weaker partners in the PTAs that they helped to proliferate, big emerging economies like India, Brazil, China, and South Africa insisted on rejecting such demands when made as part of multilateral trade rounds like Doha.

(This is perhaps the first indication that self sacrifice may be an intrinsic human trait!) Damaged by the sun, but not quite able to commit suicide, the mutated cell continues to proliferate at the expense of normal surrounding cells, resulting in a pre cancerous growth that can progress to a full blown squamous cell carcinoma.

The euro crisis has now turned the EU into something radically different. Far from being a voluntary association, the eurozone is now held together by harsh discipline far from being an association of equals it has become a hierarchical arrangement in which the center dictates policy while the periphery is increasingly subordinated instead of fraternity and solidarity, hostile stereotypes proliferate.

Unless we respond with strong governance and the necessary tools to enforce regulations, ruthless pirate fishing will continue with impunity, there will be no binding international safety standards for deep sea oil and gas drilling, and plastic pollution and abandoned fishing gear will continue to proliferate. The more the global ocean struggles for life, the more our children and future generations will struggle for theirs.

Sometimes the climate change debate looks very complicated people risk drowning in an acronym soup, technical fixes proliferate, and experts argue about the right price of carbon and appropriate discount rates. Yet, within the complexity, there is a very simple truth for a decade or more, we have known that it was risky to go on emitting greenhouse gases, yet we have utterly failed to take credible steps to stop.
