Homogenous rivers, homogenous faunas [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Habitat change and invasions of alien species are usually listed as the two biggest causes of biodiversity loss. When the two coincide, the results can be devastating, because altered habitat often favors alien species adapted to the changed conditions.

Are cryptocurrencies homogeneous? [PDF]

open access: yesEuropean Financial Management, 2019
AbstractThis article investigates if cryptocurrencies returns' are similarly affected by a selection of demand‐ and supply‐side determinants. Homogeneity among cryptocurrencies is tested via a least absolute shrinkage and selection operator (LASSO) model where determinants of Bitcoin returns are applied to a sample of 12 cryptocurrencies.

“Homogenization with non‐homogeneous plastic flow”

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, 2023
AbstractThis paper provides the solution of a homogenization model that simultaneously considers the plastic and elastic strain fields in a single analytical formulation. In addition, the authors aim to decouple plastic flows triggered in the inclusions, in the matrix at the interfaces with the inclusions, and in the matrix at a large distance from the

A homogeneous approach to testing for Granger non-causality in heterogeneous panels

open access: yesEmpirical Economics, 2020
This paper develops a new method for testing for Granger non-causality in panel data models with large cross-sectional (N) and time series (T) dimensions. The method is valid in models with homogeneous or heterogeneous coefficients.

3-Methylindole-Based Tripodal Tetraphosphine Ruthenium Complexes in N2 Coordination and Reduction and Formic Acid Dehydrogenation

open access: yesInorganics, 2017
The ruthenium(II) complexes RuCl2L1H, RuCl2L1CF3, RuCl2L1OMe and RuCl2L2H were synthesized from [Ru(η6-benzene)Cl(μ-Cl)]2 and the corresponding tripodal tris-3-methylindolephosphine-based ligands L1H, L1CF3, L1OMe, and L2H.

Discriminating between Homogeneous (AC-1) and Dense Fine Speckled (AC-2) Antinuclear Antibody Patterns: Re-Evaluation of Immunofluorescence Imaging

open access: yesBiomedicines, 2023
Antinuclear antibodies (ANAs) are essential diagnostic markers in systemic autoimmune rheumatic diseases. Among the 30 ANA patterns, homogeneous (AC-1) and dense fine speckled (AC-2) should be focused on owing to their somewhat indistinct presentation in

Verification of Human Lumbar Vertebrae and Intervertebral Disc Finite Element Models under Mechanical Forces

open access: yesASM Science Journal, 2021
Bone, being nonhomogeneous in nature need a complicated and time-consuming process to undergo computed simulation like finite element analysis. To overcome this hurdle, assuming a nonhomogeneous model as homogeneous could be a solution.
