The Potential of Hyperspectral Patterns of Winter Wheat to Detect Changes in Soil Microbial Community Composition

Reliable information on soil status and crop health is crucial for detecting and mitigating disasters like pollution or minimizing impact from soil-borne diseases. While infestation with an aggressive soil pathogen can be detected via reflected light spectra, it is unknown to what extent hyperspectral reflectance could be used to detect overall changes in soil biodiversity. We tested the hypoth...

using semblance based coherency to detect micro faults in the khangiran gas field

seismic attributes are very useful in seismic data interpretation. one of these attributes is the coherency attribute. seismic coherency is a complex trace and a geometrical attribute that is applied to a 3d cube of seismic data. it is a measure of lateral changes in acoustic impedance caused by the variation in structure, stratigraphy, lithology, porosity, and the presence of hydrocarbons. whe...

Weighted logrank tests to detect a transient improvement in survivorship.

In investigating whether an intervention has an effect on survival, we exploit the flexibility of weighted logrank tests for constructing optimal tests sensitive to specified patterns of changes in the ratios or differences of the hazards as a function of time. The tests presented seem appropriate if either the intervention on trial imposes changes in life style, such as a diet modification or ...

Runs Tests to Detect Co-Regulation Patterns in Wood Tissues

Motivation: Whole genome microarrays provide gene expression data taken from different wood tissues. An efficient and easily interpretable method is needed to assess co-regulation of adjacent genes. Results: The statistical analysis methods proposed here successfully analyzed the co-regulation of genes in several tissue types and detected different gene expression patterns. These methods can be...
