Journal Guide

It is the aim of this journal to meet two main objectives: to cover the latest research on discrete random structures, and to present applications of such research to problems in combinatorics and computer science. The goal is to provide a natural home for a significant body of current research, and a useful forum for ideas on future studies in randomness. Results concerning random graphs, hypergraphs, matroids, trees, mappings, permutations, matrices, sets and orders, as well as stochastic graph processes and networks are presented with particular emphasis on the use of probabilistic methods in combinatorics as developed by Paul Erdos. The journal focuses on probabilistic algorithms, average case analysis of deterministic algorithms, and applications of probabilistic methods to cryptography, data structures, searching and sorting. The journal also devotes space to such areas of probability theory as percolation, random walks and combinatorial aspects of probability. Manuscripts should be submitted via email to the Managing Editor, Malgorzata Bednarska at random@amu.edu.pl . Information for contributors appears in the journal as space allows, and is available at http://onlinelibrary.wiley.com/resolve/openurl?genre=journal&issn=1042-9832/authors.html.

Rangeland Ecology & Management publishes all topics-including ecology, management, socioeconomic and policy-pertaining to global rangelands. The journal's mission is to inform academics, ecosystem managers and policy makers of science-based information to promote sound rangeland stewardship. Author submissions are published in five manuscript categories: original research papers, high-profile forum topics, concept syntheses, as well as research and technical notes.Rangelands represent approximately 50% of the Earth's land area and provision multiple ecosystem services for large human populations. This expansive and diverse land area functions as coupled human-ecological systems. Knowledge of both social and biophysical system components and their interactions represent the foundation for informed rangeland stewardship. Rangeland Ecology & Management uniquely integrates information from multiple system components to address current and pending challenges confronting global rangelands.

The Society for Range Management is the professional society dedicated to supporting persons who work with rangelands and have a commitment to their sustainable use. Rangelands comprise almost one-half of all the lands in the world. They are extremely important to society for the goods and services they produce and for the ecological services they provide. SRM is dedicated to the conservation and sustainable management of rangelands for the benefit of current societies and for future generations.

Rapid Communications in Mass Spectrometry is a journal whose aim is the rapid publication of original research results and ideas on all aspects of mass spectrometry. There is no formal limit on paper length, but papers should be of a length that is commensurate with the importance and complexity of the results being reported. Contributions may deal with methods, techniques and applications, or with the interpretation of results. In general, submissions that use conventional MS, GC-MS or LC-MS methods to catalogue or screen for components of extracts including Traditional Chinese Medicines are discouraged, except where the authors can clearly demonstrate that their contribution represents a significant extension of the capabilities or applications of mass spectrometry or new understanding of ion chemistry and related disciplines.

Rapid Prototyping Journal is the world's leading journal covering additive manufacturing and related technologies.

Aims & Scope: Rare Diseases is a peer-reviewed journal that publishes high-quality research addressing the underlying mechanisms of rare diseases. In the US, a disease or disorder is considered rare when it affects less than 200,000 people at any given time. In the EU, a disease or disorder is considered rare when it affects less than 1 in 2,000 people. Our goals are to publish original research articles and to raise awareness about rare diseases. Rare Diseases covers a range of topics including studies of disease-related proteins, analyses of rare disease mutations, gene expression analyses of rare disease genes, genotype-phenotype correlations, studies of animal models, and novel clinical findings.

The scope of Rare Metal Materials and Engineering is development, production and testing of titanium, refractory metals, noble metals, rare metals, rare earth metals and superconducting materials. Meanwhile, design and fabrication technology of ceramic materials, magnetic materials, nanophase materials, biological materials and advanced materials are also included moderately.

Peer-reviewed and published bimonthly, Rare Metals is the official journal of the Nonferrous Metals Society of China. The journal is dedicated to the publication and the dissemination of original research articles (and occasional invited reviews) in the field of rare metals to establish a platform of communication between engineers and scientists. Its coverage includes the metallurgy, processing, and determination of rare metals. The journal also publishes papers on the application of rare metals in advanced materials, such as superconductors, semiconductors, composites, and ceramics.
