Advancements and Challenges in the Production of Biosurfactants: A Path Toward Sustainable Surfactant Alternatives

open access: yesChemBioEng Reviews, Volume 13, Issue 1, February 2026.
Microorganisms generate versatile biosurfactants with a wide range of uses. Although cost issues still exist, industrial interest is growing because to the advantages of sustainability, which are enhanced by genetic engineering; life cycle evaluation is crucial for scalable, environmentally responsible production.

Infinite flags and Schubert polynomials

open access: yesForum of Mathematics, Sigma
We study Schubert polynomials using geometry of infinite-dimensional flag varieties and degeneracy loci. Applications include Graham-positivity of coefficients appearing in equivariant coproduct formulas and expansions of back-stable and enriched ...

Untwisting the symmetries of β-deformed Super-Yang-Mills

open access: yesJournal of High Energy Physics, 2017
We demonstrate that the planar real-β-deformed Super-Yang-Mills theory possesses an infinitely-dimensional Yangian symmetry algebra and thus is classically integrable.

Barium‐Catalyzed Dehydrocoupling of Terminal Alkynes and Hydrosilanes

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
A combined experimental, kinetic, and theoretical investigation reveals that molecular barium catalysts mediate competently the controlled dehydrocoupling of terminal alkynes and hydrosilanes for the production of alkynylsilanes. The dehydrocoupling of terminal alkynes and hydrosilanes catalyzed by alkaline‐earth complexes: calcium, strontium and, most

Scalar products of Bethe vectors in the models with gl(m|n) symmetry

open access: yesNuclear Physics B, 2017
We study scalar products of Bethe vectors in the models solvable by the nested algebraic Bethe ansatz and described by gl(m|n) superalgebra. Using coproduct properties of the Bethe vectors we obtain a sum formula for their scalar products.

Fun from none: deformed symmetries and Fock space

open access: yes, 2009
We give a pedagogical introduction to the basics of deformations of relativistic symmetries and the Hilbert spaces of free quantum fields built as their representations.

Water Relationships of Whey Permeate Powders

open access: yesJournal of Food Science, Volume 91, Issue 2, February 2026.
ABSTRACT Water relationships are developed for whey protein permeate powders based on an analysis of the composition, structural organization, and thermal properties of three commercial whey permeate powders (WPPs). On the basis of microscopic analysis, a two‐phase model of permeate powders with two types of particle morphologies is proposed: (1 ...

Feeding a Multi-Enzyme Blend to Enhance the Nutrient Digestibility of Wheat-Canola Expeller Diets in Ileal-Cannulated Weaned Pigs

open access: yesAnimals
Canola expeller (CE) contains ~200 g/kg residual oil, but also fiber that impairs nutrient digestibility in weaned pigs. To study if feed enzymes increase digestibility, six diets containing either the basal or two CE samples mixed in at 250 g/kg (CE-A ...

On partial inverse operations in the class of preradicals of modules

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In the present work two partial operations in the class of preradicals ℙℝ of the category R-Mod of left R-modules are defined and investigated. They are inverse operations for product with respect to meet and coproduct with respect to join.

A Morse theoretic description of the Goresky-Hingston product

open access: yes, 2018
The Goresky-Hingston coproduct was first introduced by D. Sullivan and later extended by M. Goresky and N. Hingston. In this article we give a Morse theoretic description of the coproduct.
