Homogeneous algebras [PDF]

open access: yesJournal of Algebra, 2002
Various concepts associated with quadratic algebras admit natural generalizations when the quadratic algebras are replaced by graded algebras which are finitely generated in degree 1 with homogeneous relations of degree N.

Igniting homogeneous nucleation [PDF]

open access: yesPhysical Review E, 2004
Transient homogeneous nucleation is studied in the limit of large critical sizes. Starting from pure monomers, three eras of transient nucleation are characterized in the classic Becker-D\"oring kinetic equations with two different models of discrete ...

Cu-Catalyzed Arylation of Bromo-Difluoro-Acetamides by Aryl Boronic Acids, Aryl Trialkoxysilanes and Dimethyl-Aryl-Sulfonium Salts: New Entries to Aromatic Amides

open access: yesMolecules, 2021
We describe a mechanism-guided discovery of a synthetic methodology that enables the preparation of aromatic amides from 2-bromo-2,2-difluoroacetamides utilizing a copper-catalyzed direct arylation.

Homogeneous operators and homogeneous integral operators [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2021
We introduce and study in a general setting the concept of homogeneity of an operator and, in particular, the notion of homogeneity of an integral operator. In the latter case, homogeneous kernels of such operators are also studied. The concept of homogeneity is associated with transformations of a measure—measure dilations, which are most natural in ...

Asymptotic Tail Probability of the Discounted Aggregate Claims under Homogeneous, Non-Homogeneous and Mixed Poisson Risk Model

open access: yesRisks, 2021
In this paper, we derive a closed-form expression of the tail probability of the aggregate discounted claims under homogeneous, non-homogeneous and mixed Poisson risk models with constant force of interest by using a general dependence structure between ...

The Effect of Group type and Mediation type in Group Dynamic Assessment on the Improvement of Iranian Homogeneous and Heterogeneous EFL Learners' Listening Comprehension [PDF]

open access: yesJournal of Language Horizons, 2023
Based on Vygotsky's concept of Zone of Proximal Development, dynamic assessment (DA) has at its core the integration of assessment and instruction through mediation. DA is practiced either individually or collectively. In group-dynamic assessment (G-DA),

Liutex-Represented Vortex Spectrum in Turbulence

open access: yesEntropy, 2022
The Liutex vector is new quantity introduced to represent the rigid-body rotation part of fluid motion and thus to define and identify vortices in various flows. In this work, the intermittency and power-law similarity of the Liutex vector in homogeneous,

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.

Sensitive, homogeneous, and label-free protein-probe assay for antibody aggregation and thermal stability studies

open access: yesmAbs, 2021
Protein aggregation is a spontaneous process affected by multiple external and internal properties, such as buffer composition and storage temperature.
