Enriched order polytopes and enriched Hibi rings [PDF]
European Journal of Mathematics, 2020 AbstractStanley introduced two classes of lattice polytopes associated to posets, which are called the order polytope $${{\mathscr {O}}}_P$$ O P and the chain polytope $${{\mathscr {C}}}_P$$ C P

Extreme enrichment in atmospheric 15N15N. [PDF]
, 2017 Molecular nitrogen (N2) comprises three-quarters of Earth's atmosphere and significant portions of other planetary atmospheres. We report a 19 per mil (‰) excess of 15N15N in air relative to a random distribution of nitrogen isotopes, an enrichment that ...

Petroleum Science, 2019 This paper presents a three-dimensional, three-phase compositional model considering CO2 phase equilibrium between water and oil. In this model, CO2 is mutually soluble in aqueous and hydrocarbon phases, while other components, except water, exist in ...

Enrichment of organic carbon in sediment transport by interrill and rill erosion processes [PDF]
, 2008 Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments.

Chemical Enrichment at High Redshifts [PDF]
, 1998 We have tried to understand the recent observations related to metallicity in Ly $\alpha$ forest clouds in the framework of the two component model suggested by Chiba & Nath (1997).

Electronic Notes in Theoretical Computer Science, 2008 AbstractA category with biproducts is enriched over (commutative) additive monoids. A category with tensor products is enriched over scalar multiplication actions. A symmetric monoidal category with biproducts is enriched over semimodules. We show that these extensions of enrichment (e.g.

State transitions as morphisms for complete lattices [PDF]
, 1999 We enlarge the hom-sets of categories of complete lattices by introducing `state transitions' as generalized morphisms. The obtained category will then be compared with a functorial quantaloidal enrichment and a contextual quantaloidal enrichment that ...
