A supersymmetric extension of w 1+∞ algebra in the celestial holography

open access: yesJournal of High Energy Physics
We determine the N $$ \mathcal{N} $$ = 1 supersymmetric topological W ∞ algebra by using the λ deformed bosons (β, γ) and fermions (b, c) ghost system. By considering the real bosons and the real fermions at λ = 0 (or λ = 1 2 $$ \frac{1}{2} $$ ), the N $$

Extensions of modules for twisted current algebras [PDF]

open access: yesarXiv, 2017
Twisted current algebras are fixed point subalgebras of current algebras under a finite group action. Special cases include equivariant map algebras and twisted forms of current algebras. Their finite-dimensional simple modules fall into two categories, those which factor through an evaluation map and those which do not.

Optimal control of axial dispersion tubular reactors with recycle: Addressing state‐delay through transport PDEs

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The boundary‐regulated distributed parameter system of an axial dispersion tubular reactor with delayed recycle is showcased, along with the optimal observer‐based control strategy developed using a late‐lumping method for its stabilization. Abstract The optimal control of an axial tubular reactor with a recycle stream is addressed as a key type of ...

Quasi-finite algebras graded by Hamiltonian and vertex operator algebras [PDF]

open access: yesarXiv, 2005
A general notion of a quasi-finite algebra is introduced as an algebra graded by the set of all integers equipped with topologies on the homogeneous subspaces satisfying certain properties. An analogue of the regular bimodule is introduced and various module categories over quasi-finite algebras are described.

Regularization of current algebra

open access: yes, 1993
In this talk I want to explain the operator substractions needed to regularize gauge currents in a second quantized theory. The case of space-time dimension $3+1$ is considered in detail. In presence of chiral fermions the regularization effects a modification of the local commutation relations of the currents by local Schwinger terms.

Corn cob pyrolysis: A systematic literature review of methods and applications

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Two‐phase model for the excavation analysis in partially saturated soft soils using the particle finite element method

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023
Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...

On deformed double current algebras for simple Lie algebras [PDF]

open access: yesarXiv, 2016
We prove the equivalence of two presentations of deformed double current algebras associated to a complex simple Lie algebra, the first one obtained via a degeneration of affine Yangians while the other one naturally appeared in the construction of the elliptic Casimir connection.
