We study some structural and combinatorial properties of Sturmian palindromes, i.e., palindromic finite factors of Sturmian words. In particular, we give a formula which permits to compute in an exact way the number of Sturmian palindromes of any length. Moreover, an interesting characterization of Sturmian palindromes is obtained.

Abstract. We consider Stokes’ conjecture concerning the shape of the extremal two-dimensional water wave. By new geometric methods including a nonlinear frequency formula, we prove Stokes’ conjecture in the original variables. Our results do not rely on structural assumptions needed in previous results such as isolated singularities, symmetry and monotonicity. Part of our results extends to the...

Desferal, deferoxamine mesylate USP, is an iron-chelating agent, available in vials for intramuscular, subcutaneous, and intravenous administration. Desferal is supplied as vials containing 500 mg and 2 g of deferoxamine mesylate USP in sterile, lyophilized form. Deferoxamine mesylate is N-[5-[3-[(5­ aminopentyl)hydroxycarbamoyl]propionamido]pentyl]-3-[[5-(N­ hydroxyacetamido)pentyl]carbamoyl]p...

In this issue of Neuron, Stepanyants, Hof, and Chklovskii derive a simple mathematical formula to calculate, from measurable anatomical parameters, the capacity for neuronal wiring plasticity involving local synaptic rearrangements. Their work provides a deeper understanding of the potential contribution of structural plasticity to learning and memory.

Adriamycin, a new antitumour antibiotic of the anthracycline group with a structural formula very similar to daunorubicin, has proved to have potent tumour-growth-inhibiting properties, and to be particularly effective in childhood malignancies. Though adriamycin produces a higher percentage of side-effects than daunorubicin-namely, stomatitis and alopecia-a lower dosage may be used for therapy.

The STRIP system is a theorem prover for intuitionistic propositional logic with two main characteristics: it deals with the duplication of formulae during proof-search from a fine and explicit management of formulae (as resources) based on a structural sharing and it builds, for a given formula, either a proof or a countermodel.
