The World Conservation Union (IUCN) Red List is widely recognized as the most authoritative and objective system for classifying species by their risk of extinction. Red List Indices (RLIs) illustrate the relative rate at which a particular set of species change in overall threat status (i.e. projected relative extinction-risk), based on population and range size and trends as quantified by Red...

This short communication discusses an algorithm suited for the generation of periodic microstructures of granular media. Its particular features are a user-defined grain size distribution, a representative volume element which is intrinsically periodic ab initio and a user-defined termination criterion, controlled by an increase of volume fraction. For low densities our particle packings resemb...

Future coastal flood risk will be strongly influenced by sea-level rise (SLR) and changes in the frequency and intensity of tropical cyclones. These two factors are generally considered independently. Here, we assess twenty-first century changes in the coastal hazard for the US East Coast using a flood index (FI) that accounts for changes in flood duration and magnitude driven by SLR and change...

Poor diet may represent one pathway through which lower socioeconomic position (SEP) leads to adverse health outcomes. This study examined the associations between SEP and diet quality, its components, energy, and nutrients in a nationally representative sample of Australians. Dietary data from two 24-h recalls collected during the cross-sectional Australian Health Survey 2011-13 (n = 4875; age...

The Leiden Imaging and Multi-media (LIM) group develops visual search tools for content-based image indexing and retrieval. Because visual searches take place in an interactive setting, the methods used have to be fast. Research addressed in this paper deals with ”How to get quickly acquainted with the contents of a large digital image collection”. More formally spoken we have tried to speed-up...

We present an empirical comparison of major classification algorithms when training data contains attribute noise levels not representative of field data. Although conventional wisdom indicates that training data should contain noise representative of field data, it can be difficult to ensure representative noise levels. To study classification algorithm sensitivity, we develop an innovative ex...
