Various plant indexes are used or recommended for bioindication. However, the nonmonotonic dose-response dependences (hormesis and paradoxical effects) of these indexes are insufficiently explored upon exposure to pollution. We studied the dependences of these Betula pendula indexes on the intensity of motor traffic pollution. Regression analysis did not reveal any dependence of chlorophyll and...

BACKGROUND Information available on the internet has changed patient-neurologist relationships. Its evaluation for multiple sclerosis is only partial, regardless of the language used. OBJECTIVE We aim to evaluate the content quality and ranking indexes of French-language sites dealing with multiple sclerosis. METHODS Two French terms and three search engines were used to identify the sites ...

Evaluating clustering results is a fundamental task in microarray data analysis, due to the lack of enough biological knowledge to know in advance the true partition of genes. Many quality indexes for gene clustering evaluation have been proposed. A critical issue in this domain is to compare and aggregate quality indexes to select the best clustering algorithm and the optimal parameter setting...

The Pantanal is the largest floodplain of globe occupying 138,183 km2 in Brazil. fundamental ecological factor interaction between ecosystems flooding regime. Connected to properties soil-plant-atmosphere system, knowledge on soil water content becomes increasingly necessary. high temporal and spatial variability caused by vast heterogeneity texture, vegetation, topography climate makes it a di...

INTRODUCTION Today’s genetic evaluation schemes involve models comprising multiple, correlated additive genetic effects for each animal. These can be multi-trait (MT) models or random regression (RR) models which model trajectories in traits recorded repeatedly per animal through a set of RR coefficients. Often we are interested in linear functions of the resulting breeding value (EBV) estimate...

For the analysis of vegetation areas using satellites, a variety of vegetation indexes such as NDVI and EVI have been developed. However, most indexes have weak response to grasping the type and quality (the growth state and situation) of vegetation. To grasp these vegetation characteristics, we have developed new vegetation indexes, i.e. shadow index (SI) and water stress trend (WST). We estim...

A content-based image retrieval mechanism to support complex similarity queries is presented. The image content is defined by three kinds of features: quantifiable features describing the visual information, non-quantifiable features describing the semantic information, and keywords describing more abstract semantic information. In correspondence with these feature sets, we construct three type...
