Nonlinear dimensionality reduction of gene expression data

Using microarray measurements techniques, it is possible to measure the activity of genes simultaneously across the whole genome. Since genes influence each others activity levels through complex regulatory networks, such gene expression measurements are state samples of a dynamical system. Gene expression data has proven useful for diagnosis and definition of disease subgroups, for inference of t

Comparing parametric and non-parametric approaches for estimating trends in multi-year NDVI

The aim of this study is to systematically compare parametric and non-parametric techniques for analyzing trends in annual NDVI derived from NOAA AVHRR sensor in order to examine how trend type and departure from normality assumptions affect the accuracy of detecting long-term change. To generate annual data, the mean NDVI of a four-month long ‘green’ season was computed for fifteen sites (located

A Future Legal Coordinated Cadastre for Sweden?

This paper initially presents an introduction to the Swedish land administration system, particularly focusing on the parts of the Real Property Register that compose the cadastre. Here, a brief retrospect of the long tradition of land related registration follows by an account of the current components, functions and parties concerned. The second part of the paper then discusses a vision, express

What is the value of L1-to-L2 translation for advanced learners?

This paper presents findings from a longitudinal, experimental project investigating the effect of translation on the morphosyntactic accuracy of advanced Swedish (L1) learners of English (L2). The subjects were first-year students of English at a Swedish university. The curriculum was communicative and translation (Focus-on-Forms) was used judiciously. The research is couched in cognitive psycho
