Interaction of non-Abelian tensor gauge fields

open access: yesPhysics Letters B, 2018
The non-Abelian tensor gauge fields take value in extended Poincaré algebra. In order to define the invariant Lagrangian we introduce a vector variable in two alternative ways: through the transversal representation of the extended Poincaré algebra and ...

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Branching Laws for Some Unitary Representations of SL(4,R)

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
In this paper we consider the restriction of a unitary irreducible representation of type A_q(λ) of GL(4,R) to reductive subgroups H which are the fixpoint sets of an involution. We obtain a formula for the restriction to the symplectic group and to GL(2,

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Approximation by Quantum Circuits [PDF]

open access: yes, 1995
In a recent preprint by Deutsch et al. [1995] the authors suggest the possibility of polynomial approximability of arbitrary unitary operations on $n$ qubits by 2-qubit unitary operations.

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

The analysis of complex phonetic elements in Bura and the syllable

open access: yesStudies in African Linguistics, 1983
This paper examines those complex phonetic elements in Bura (and related languages such as Margi) which have been described by earlier scholars as unitary segments having a labial-alveolar double articulation.

On the extensions of infinite-dimensional representations of Lie semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The necessary and sufficient conditions have been obtained for extendability of a Banach representation of a generating Lie semigroup S to a local representation of the Lie group G generated by S when the tangent wedge of S is a Lie semialgebra. The most

Tokenism or Catalytic? Exploring Board Gender Diversity Through the Lens of SDG 9 Outcomes in the EU Context

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the relationship between Executive gender diversity (EGD) and the achievement of Sustainable Development Goal 9 (SDG 9—Industry, Innovation, and Infrastructure) in the European Union. It investigates whether female representation in corporate governance contributes to innovation‐driven sustainability.

Internationalising the teacher education curriculum: An analysis of syllabi and student experiences

open access: yesThe Curriculum Journal, EarlyView.
Abstract Internationalisation has increasingly become a key dimension of quality in initial teacher education (ITE) programmes. Although it is recognised as a means to strengthen future teachers' competencies and expand their professional knowledge, it remains underdeveloped in practice.
