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.

Mediated homogenization [PDF]

open access: yesPhysical Review A, 2007
Homogenization protocols model the quantum mechanical evolution of a system to a fixed state independently from its initial configuration by repeatedly coupling it with a collection of identical ancillas. Here we analyze these protocols within the formalism of "relaxing" channels providing an easy to check sufficient condition for homogenization.

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

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.

Homogeneity and Supply [PDF]

open access: yesAmerican Journal of Agricultural Economics, 2008
AbstractSupply functions in the ubiquitous Gorman class are examined for their homogeneity properties. Homogeneity places surprisingly strong restrictions on functional forms. These forms facilitate testing of aggregability given homogeneity or homogeneity given aggregability or testing both.

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.

Homogeneous Electrochemical Aptamer Sensor Based on Two-Dimensional Nanocomposite Probe and Nanochannel Modified Electrode for Sensitive Detection of Carcinoembryonic Antigen

open access: yesMolecules, 2023
A rapid and convenient homogeneous aptamer sensor with high sensitivity is highly desirable for the electrochemical detection of tumor biomarkers. In this work, a homogeneous electrochemical aptamer sensor is demonstrated based on a two-dimensional (2D ...

Synthesis of Uranium-Thorium dioxide nano powder using supercritical hydrothermal method [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2021
Due to the limited uranium reserves and advantages of thorium fuels over uranium fuels, the development of the thorium fuel cycle in various countries including Iran, has been considered significantly.

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.
