Greater sage‐grouse seasonal habitat associations: A review and considerations for interpretation and management applications

The Journal of Wildlife Management, EarlyView.
We examined habitat associations from second‐ and third‐order habitat selection studies conducted on greater sage‐grouse and summarize the types of designs used and the qualitative associations reported. We suggest a combination of study design choices and context‐dependence selection patterns can prohibit the transferability of study findings when the

A novel approach to touch voltage risk assessment for gas pipelines in shared transmission corridors

IET Science, Measurement &Technology, Volume 17, Issue 1, Page 27-36, January 2023., 2023
Abstract Touch voltages are more likely to appear on long‐distance pipelines that lie in shared corridors with transmission lines. The touch voltage level varies with soil resistivity and can become hazardous while maintenance is being undertaken, necessitating risk assessment.

DiffusionVel: Multi-Information Integrated Velocity Inversion Using Generative Diffusion Models [PDF]

arXiv
Full waveform inversion (FWI) is capable of reconstructing subsurface properties with high resolution from seismic data. However, conventional FWI faces challenges such as cycle-skipping and high computational costs. Recently, deep learning method has emerged as a promising solution for efficient velocity estimation.

Fast reaction limit of reaction-diffusion systems [PDF]

arXiv, 2019
Singular limit problems of reaction-diffusion systems have been studied in cases where the effects of the reaction terms are very large compared with those of the other terms. Such problems appear in literature in various fields such as chemistry, ecology, biology, geology and approximation theory.

Efficient data reduction for time‐of‐flight neutron scattering experiments on single crystals

Journal of Applied Crystallography, Volume 55, Issue 6, Page 1514-1527, December 2022., 2022
In neutron scattering experiments, data sets with different statistical significance are collected. A new method is presented to efficiently calculate the weights of single‐crystal time‐of‐flight measurements, and to add together the various contributions.Event‐mode data collection presents remarkable new opportunities for time‐of‐flight neutron ...

The Mediterranean deep-sea fauna: historical evolution, bathymetric variations and geographical changes [PDF]

Carnets de G\'{e}ologie / Notebooks on Geology Article 2004/01 (CG2004_A01_CCE-PG) (2004) 10 p., 4 fig., 3 tabl, 2005
The deep-water fauna of the Mediterranean is characterized by an absence of distinctive characteristics and by a relative impoverishment. Both are a result of events after the Messinian salinity crisis (Late Miocene). The three main classes of phenomena involved in producing or recording these effects are analysed and discussed: - Historical ...

Diagnosing coastal processes using machine learning and ocean buoyancy gliders

Limnology and Oceanography, EarlyView.
Abstract Ocean buoyancy gliders provide a comprehensive view of the water column, offering more than simply a snapshot of a single moment in time or space. In this study, we applied the established machine learning method, k‐means clustering, to a glider dataset collected in the summer of 2015 in the northern Gulf of Mexico.

Preparation of pyrite concentrate powder from the Thackaringa mine for quantitative phase analysis using X‐ray diffraction

Journal of Applied Crystallography, Volume 55, Issue 6, Page 1572-1582, December 2022., 2022
A method for performing accurate quantitative phase analysis using X‐ray powder diffraction of pyrite concentrate mineral samples from the Thackaringa mine has been devised. The sample preparation optimization process is described. Grain size reduction suitable for analysis by the Rietveld method was achieved using ball milling.The quantitative phase ...
