Operations Research Letters is a publication for literature on all aspects of operations research and the management and decision sciences. The features distinguishing it from other journals in the field are* Concise articles, generally limited to 6 journal pages* Extended abstracts of two to four, announcing results without full proofs;* Rapid review and fast publication;* Broad coverage of the literature.Apart from the page limitation, originality, relevance, quality and clarity are the only criteria for selecting the material to be published. A sound methodological basis is a requirement, but technical correctness alone is not sufficient for publication. The subject matter can be theory, methodology, empirical studies, and applications. The mainstream of contributions focuses on new models, theorems, algorithms, and experimental work that the author wants to disseminate rapidly. We will publish theory and methodology with proofs omitted or only sketched, provided that the author submits support material that enables us to verify the findings. We will also publish computational and experimental studies that are not necessarily based on new theory or methodology, but are of significant scientific value because they confirm or refute prior results. Similarly, we will publish reports on applications and case studies that demonstrate a novel use of existing techniques or contain significant ideas about data collection and analysis, modelling, or implementation.Area Editors:Approximation and heuristicsGerhard J.

PLoS Computational Biology features works of exceptional significance that further our understanding of living systems at all scales—from molecules and cells, to patient populations and ecosystems—through the application of computational methods. Readers include life and computational scientists, who can take the important findings presented here to the next level of discovery.Research articles that primarily describe new methods and offer only limited biological insight will be considered only in those exceptional instances in which the method is expected to significantly impact the field of computational biology, typically making substantial breakthroughs in areas of demonstrated importance. Research articles modeling aspects of biological systems should demonstrate both scientific novelty and profound new biological insights. Research articles describing improved or routine methods, models, software, and databases will not be considered by PLoS Computational Biology, and may be more appropriate for PLoS ONE.Generally, reliability and significance of biological discovery are validated and enriched by experimental studies. Experimental validation is not required for publication, however, nor does experimental validation of a modest biological discovery render a manuscript suitable for PLoS Computational Biology.For all submissions, authors must clearly provide detail, data, and software to ensure readers' ability to reproduce the models, methods, and results.Authors unsure of whether their work is within the scope of the journal should submit a presubmission inquiry.

We welcome your ideas and experiences.

We establish universal inequalities for the eigenvalues of the clamped plate problem on compact submanifolds of Euclidean space, of spheres and of real, complex and quaternionic projective spaces. We prove similar results for the biharmonic operator on domains of Riemannian manifolds that admit spherical eigenmaps (this includes compact homogeneous Riemannian spaces) and finally on domains of hyperbolic space.
