Accelerating the computation for real-time application of the sinc function using graphics processing units

open access: yesJournal of Analytical Science and Technology, 2020
In magnetic resonance imaging, the fidelity of image reconstruction is an important criterion. It has been suggested that the infinite-extent sinc kernel is the ideal interpolation kernel for ensuring the reconstruction quality of non-Cartesian ...

Dipole symmetry breaking and fractonic Nambu-Goldstone mode

open access: yesSciPost Physics Core, 2023
We introduce a family of quantum field theories for fields carrying monopole and dipole charges. In contrast to previous realizations, fields have quadratic two-derivative kinetic terms.

Congruence kernels of orthomodular implication algebras

open access: yesDiscrete Mathematics, 2008
AbstractAbstracting from certain properties of the implication operation in Boolean algebras leads to so-called orthomodular implication algebras. These are in a natural one-to-one correspondence with families of orthomodular lattices. It is proved that congruence kernels of orthomodular implication algebras are in a natural one-to-one correspondence ...

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.

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Lie group classification and exact solutions of the generalized Kompaneets equations

open access: yesElectronic Journal of Differential Equations, 2015
We study generalized Kompaneets equations (GKEs) with one functional parameter, and using the Lie-Ovsiannikov algorithm, we carried out the group classification. It is shown that the kernel algebra of the full groups of the GKEs is the one-dimensional

Kernel Interpolation for Scalable Structured Gaussian Processes (KISS-GP) [PDF]

open access: yes, 2015
We introduce a new structured kernel interpolation (SKI) framework, which generalises and unifies inducing point methods for scalable Gaussian processes (GPs).

The Discretization‐Corrected Particle Strength Method for the Barotropic Vorticity Equations

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
Numerical solution for the barotropic vorticity equation in complex geometry using the meshless point collocation method. The spatial domain is represented by a set of nodes. The collocation method numerically solves the strong form governing equations.

Bispectrality of the Complementary Bannai-Ito Polynomials

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
A one-parameter family of operators that have the complementary Bannai-Ito (CBI) polynomials as eigenfunctions is obtained. The CBI polynomials are the kernel partners of the Bannai-Ito polynomials and also correspond to a q→−1 limit of the Askey-Wilson ...
