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 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 کاملFunctional gene cassettes in development.
It has been noted in recent years that groups ofgenes are often used at multiple stages and multiple places of development. Comparison of the functions of each group of genes in different developmental context gave rise to the notion of "functional gene cassettes." These groups of genes can often be viewed as sets of tools; each group is suited to carry out a certain operation and may serve sim...
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...
