Homogeneity and h -homogeneity

Topology and its Applications, 2013
A topological space \(X\) is \textit{homogeneous} if each of its points can be carried to any other via a homeomorphism of the space; \(X\) is \textit{\(h\)-homogeneous} if it is homeomorphic to each of its nonempty clopen subspaces. The author investigates conditions under which these two notions are related for zero-dimensional spaces. The first main

Homogeneous algebras

Journal of Algebra, 2003
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. Such algebras are referred to as {\sl homogeneous algebras of degree N}.

Optical characteristics and mechanism analysis of polycarbonate/poly(1, 4-cyclohexanedimethyl- 1, 4-cyclohexanedicarboxylate) blends

Cailiao gongcheng, 2022
PC/PCCD blends with different PCCD contents were prepared by melt blending. The optical performance test results show that PC/PCCD blends have high light transmittance and low haze.

Design and Synthesis of Ferrite Strip-Line Circulator Based on Enhanced Closed Form Solution and Power Handling Analysis

IEEE Access, 2022
In this article, Y-junction strip-line circulators are designed using an enhanced closed form solution consisting of unified key equations and a flowchart design, which serves as a direct procedure for designing a ferrite circulator.

Non-formal Homogeneous Spaces

, 2012
Several large classes of homogeneous spaces are known to be formal---in the sense of Rational Homotopy Theory. However, it seems that far fewer examples of non-formal homogeneous spaces are known.

Homogeneity and Supply [PDF]

American 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.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Synthesis and investigation of physico-chemical properties of dicationic ionic liquids [PDF]

Royal Society Open Science, 2018
A series of dicationic ionic liquids (ILs) including [C4(MIM)2][PF6]2, [C5(MIM)2][PF6]2, [C6(MIM)2][PF6]2 and [C4(PYR)2][PF6]2 were synthesized. Their thermal stability and melting points were analysed.
