Pushing Up The Daisies
When components of an interacting dynamical system (such as organs within an organism, or daisies within the Daisyworld model) have a limited range of viability to changes in some essential variable, intuition suggests that increasing any individual range of viability will also increase viability in the context of the whole system. We show circumstances in which the reverse is true.

Tolerance of the lip mucosa of NMRI mice to single and fractionated irradiation combined with cis-diamminedichloroplatinum (II) (cis-DDP) was investigated. For the various combination schedules total drug doses varying from 6mgkg-1 to 13mgkg-1 were injected i.p. It was found that cis-DDP did not alter the radiation sensitivity of this tissue at any of the time intervals tested (ranging from 24 ...
متن کاملFrom Neural Arbors to Daisies
Pyramidal neurons in layers 2 and 3 of the neocortex collectively form an horizontal lattice of long-range, periodic axonal projections, known as the superficial patch system. The precise pattern of projections varies between cortical areas, but the patch system has nevertheless been observed in every area of cortex in which it has been sought, in many higher mammals. Although the clustered axo...
متن کاملMolecular Palaeontology
In the broadest possible sense, molecular palaeontology might encompass any and all chemical traces left by onceliving organismsorby their life processes.Thiswould cover fields ranging from isotope geochemistry and biomineralization to molecular biology. However, in a more restricted sense, molecular palaeontology is the study of complex organic molecules made by once-living organisms. In some ...
متن کاملDaisies and Other Turán Problems
Our aim in this note is to make some conjectures about extremal densities of daisy-free families, where a ‘daisy’ is a certain hypergraph. These questions turn out to be related to some Turán problems in the hypercube, but they are also natural in their own right. We start by giving the daisy conjectures, and some related problems, and shall then go on to describe the connection with vertex-Tur...
