One to rule them all
The development of transposon-based genome manipulation tools can benefit greatly from understanding transposons' inherent regulatory mechanisms. The Tc1-mariner transposons, which are being widely used in biotechnological applications, are subject to a self-inhibitory mechanism whereby increasing transposase expression beyond a certain point decreases the rate of transposition. In a recent pap...
متن کاملNumber one cause of stress
Rest assured, you're not alone ? people of all ages experience stress at some point during their lives. Since people have different stressors and experience stress differently, it?s difficult to pinpoint or rank the number one cause. But, it might actually surprise you that stress can be beneficial ? and in some cases critical ? in helping individuals respond and adapt to new situations in life...

متن کاملLooking for vertex number one
Given an instance of the preferential attachment graph Gn = ([n], En), we would like to find vertex 1, using only ‘local’ information about the graph; that is, by exploring the neighborhoods of small sets of vertices. Borgs et. al gave an an algorithm which runs in time O(log n), which is local in the sense that at each step, it needs only to search the neighborhood of a set of vertices of size...
متن کاملOn Termination of One Rule Rewrite Systems
The undecidability of the termination of rewrite systems is usually proved by reduction to the halting of Turing machines. In particular, Dauchet proves the unde-cidability of the termination of one rule rewrite systems by coding Turing machines into one rule rewrite systems. Rewrite systems are a very simple model of computation and one may expect proofs in this model to be more straightforwar...
