How molecular knots can pass through each other.
We propose a mechanism in which two molecular knots pass through each other and swap positions along a polymer strand. Associated free energy barriers in our simulations only amount to a few kBT, which may enable the interchange of knots on a single DNA strand.
متن کاملQCD : how we can help each other
A brief summary is given of the outstanding issues in experimental work on the strong interaction at collider experiments. I focus particularly on those areas where more than one collider can address the same issue. (Some figures in this article are in colour only in the electronic version; see www.iop.org)
متن کاملHow Many Random Points Can a Regular Curve Pass Through?
Suppose n points are scattered uniformly at random in the unit square [0, 1]. Question: How many of these points can possibly lie on some curves of length λ? Answer, proved here: OP (λ · √ n). We consider a general class of such questions; in each case, we are given a class Γ of curves in the square, and we ask: in a cloud of n uniform random points, how many can lie on some curve γ ∈ Γ? Classe...
متن کاملAn ethnographic seduction: How qualitative research and agent-based models can benefit each other
We provide a generaI anaIyticaI framework for empiricaIIy informed agent-based simuIations. That this methodoIogy provides present-day agent-based modeIs with a sound and proper insight as to the behavior of sociaI agents — an insight that statisticaI data often faII short of providing at Ieast at a micro IeveI and for hidden and sensitive popuIations. In the other direction, simuIations can pr...
متن کاملQuality improvement around the world: how much we can learn from each other.
The USA National Forum on Quality Improvement in Health Care--organised by the Institute of Healthcare Improvement (Boston USA)--attracts many people from outside North America. At the 1999 meeting 20 countries were represented. A session on "Quality improvement around the world" was included in the pre-conference programme to bring together people working in many countries to explore and compa...
