Profile of Joachim Messing.
Joachim Messing’s father did not initially approve of his son’s decision to become a scientist. “He was a mason,” Messing explains, “and was hoping that I would just take over his business.” His mother, however, was more supportive, “because she didn’t like the rough climate on the construction sites.” Fortunately for science, his mother prevailed. Messing, the director of the Waksman Institute...
متن کاملSort-Invariant Non-Messing-Up
A poset has the non-messing-up property if it has two covering sets of disjoint saturated chains so that for any labeling of the poset, sorting the labels along one set of chains and then sorting the labels along the other set yields a linear extension of the poset. The linear extension yielded by thus twice sorting a labeled nonmessing-up poset may be independent of which sort was performed fi...
متن کاملMessing with bacterial quorum sensing.
Quorum sensing is widely recognized as an efficient mechanism to regulate expression of specific genes responsible for communal behavior in bacteria. Several bacterial phenotypes essential for the successful establishment of symbiotic, pathogenic, or commensal relationships with eukaryotic hosts, including motility, exopolysaccharide production, biofilm formation, and toxin production, are ofte...
متن کاملA Non-messing-up Phenomenon for Posets
We classify finite posets with a particular sorting property, generalizing a result for rectangular arrays. Each poset is covered by two sets of disjoint saturated chains such that, for any original labeling, after sorting the labels along both sets of chains, the labels of the chains in the first set remain sorted. We also characterize posets with more restrictive sorting properties.
متن کاملA Greek Bronze Vase
When we think of Greek vases we generally have in mind Greek pottery, which has survived in quantity. Clay, one of the most perishable of materials, becomes one of the most indestructible in the firing. In fact, much of our knowledge of ancient civilizations is derived from the potsherds that are found in successive layers on ancient sites; a pot, once fired, may break into a hundred pieces, bu...
