TOPs and their regulation.
Upon cell-cycle arrest or nutrient deprivation, the cellular rate of ribosome production is reduced significantly. In mammalian cells, this effect is achieved in part through a co-ordinated inhibition of RP (ribosomal protein) synthesis. More specifically, translation initiation on RP mRNAs is inhibited. Translational regulation of RP synthesis is dependent on cis-elements within the 5'-UTRs (5...
متن کاملTops-Only Domains
In this paper we consider the standard voting model with a finite set of alternatives A and n voters and address the following question: what are the characteristics of domains D that induce the property that every strategy-proof social choice function f : Dn → A satisfying unanimity, has the tops-only property? We first impose a minimal richness condition which ensures that for every alternati...
متن کاملCommunicating science: from the laboratory bench to the breakfast table.
If we are to maintain public appreciation and support for our scientific enterprise, we need to pay more attention to translating the benefits and grandeur of science into the language of broader society. Both educators and journalists have a role to play in communicating the achievements of science, but scientists must recognize that we have a responsibility to increase the availability and sa...
متن کاملStop Reconstruction with Tagged Tops
At the LHC combinatorics make it unlikely that we will be able to observe stop pair production with a decay to a semi-leptonic top pair and missing energy for generic supersymmetric mass spectra. Using a Standard-Model top tagger on fully hadronic top decays we can not only extract the stop signal but also measure the top momentum. To illustrate the promise of tagging tops with moderate boost w...
متن کاملOn cusps and flat tops
We develop non-invertible Pesin theory for a new class of maps called cusp maps. These maps may have unbounded derivative, but nevertheless verify a property analogous to C. We do not require the critical points to verify a non-flatness condition, so the results are applicable to C maps with flat critical points. If the critical points are too flat, then no absolutely continuous invariant proba...
