On Hopf algebroid structure of kappa-deformed Heisenberg algebra

open access: yes, 2016
The $(4+4)$-dimensional $\kappa$-deformed quantum phase space as well as its $(10+10)$-dimensional covariant extension by the Lorentz sector can be described as Heisenberg doubles: the $(10+10)$-dimensional quantum phase space is the double of $D=4 ...

Development of a Sustainable Biocatalytic Process for Geranyl Benzoate Production Using Immobilized Lipase

open access: yesChemistryOpen, EarlyView.
This study optimized solvent‐free geranyl benzoate production using Lipozyme 435, achieving 72% conversion in 6 hours. Open reactors improved yields (>99% in 48 hours) by removing inhibitorymethanol. Methyl benzoate reduced enzyme activity by 54%, though Lipura Flex showed better resistance. Human cell tests confirmed no cytotoxicity.

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

open access: yessteel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Hopf algebra of labeled simple graphs arising from super-shuffle product

open access: yesMathematical Modelling and Control
From the connections between permutations and labeled simple graphs, we generalized the super-shuffle product and the cut-box coproduct on permutations to labeled simple graphs.

Worldsheet Scattering in AdS_5 x S^5

open access: yes, 2007
We calculate the S-matrix in the gauge-fixed sigma-model on AdS_5 x S^5 to the leading order in perturbation theory, and analyze how supersymmetry is realized on the scattering states.

Coproducts of Distributive Lattice based Algebras [PDF]

open access: yesEPiC Series in Computing, 2014
The analysis of coproducts in varieties of algebras has generally been variety-specific, relying on tools tailored to particular classes of algebras. A recurring theme, however, is the use of a categorical duality. Among the dualities and topological representations in the literature, natural dualities are particularly well behaved with respect to ...

D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Energy utilization in lactating Jersey cows consuming a mixture of dried distillers grains and solubles and straw replacing alfalfa hay

open access: yesJournal of Dairy Science
: Some forages require significant amounts of water to grow, causing the dairy industry to be dependent on a limited resource. Feeding crop residues and feed coproducts in dairy rations may represent opportunities when alfalfa is not readily available ...

Formulation of Broiler Chicken Feeds Using Distillers Dried Grains with Solubles

open access: yesFermentation, 2018
Distillers dried grains with solubles (DDGS) is a coproduct of corn-based ethanol production that can be a valuable source of energy, digestible amino acids, and available phosphorus in poultry feeds.

Quotients and Hopf Images of a Smash Coproduct [PDF]

open access: yes, 2015
We describe the Hopf algebra quotients and Hopf images of the smash coproduct of a group algebra by the algebra of functions on a finite group.Comment: 17 ...
