Effect of MDP agents on the bond strength of two self-adhesive resin cements to saliva-contaminated dentin substrates. [PDF]

Eur J Oral Sci
Abstract This study investigated the influence of 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) agents and repeated saliva contamination on the microtensile bond strength (µTBS) of two self‐adhesive resin cements (SARCs) bonded to dentin. Forty‐eight sound human teeth were randomly divided into eight experimental groups, based on three factors ...

Generalization of Geyer’s commutation relations with respect to the orthogonal group in even dimensions

European Physical Journal C: Particles and Fields, 2020
A connection between the deformed Duffin–Kemmer–Petiau (DKP) algebra and an extended system of the parafermion trilinear commutation relations for the creation and annihilation operators $$a^{\pm }_{k}$$ a k ± and for an additional operator $$a_{0}$$ a 0

Celestial chiral algebras, colour-kinematics duality and integrability

Journal of High Energy Physics, 2023
We study celestial chiral algebras appearing in celestial holography, using the light-cone gauge formulation of self-dual Yang-Mills theory and self-dual gravity, and explore also a deformation of the latter.

q -deformed star products and Moyal brackets [PDF]

Journal of Mathematical Physics, 1998
The standard and antistandard ordered operators acting on two-dimensional q-deformed phase space are shown to satisfy algebras which can be called q−W∞. q-star products and q-Moyal brackets corresponding to these algebras are constructed. Some applications like defining q-classical mechanics and q-path integrals are discussed.

Quantum normal forms, Moyal star product and Bohr–Sommerfeld approximation [PDF]

Journal of Physics A: Mathematical and General, 2005
Summary: A normal form transformation is carried out on one-dimensional quantum Hamiltonians that transforms them into functions of the quantum harmonic oscillator. The method works with the Weyl transform (or `symbol') of the Hamiltonian. The Moyal star product is used to carry out the normal form transformation at the level of symbols.

Quantized Coulomb branches, monopole bubbling and wall-crossing phenomena in 3d N $$ \mathcal{N} $$ = 4 theories

Journal of High Energy Physics, 2020
To study the quantized Coulomb branch of 3d N $$ \mathcal{N} $$ = 4 unitary SQCD theories, we propose a new method to compute correlators of monopole and Casimir operators that are inserted in the ℝ × ℝ ϵ 2 $$ \mathrm{\mathbb{R}}\times {\mathrm{\mathbb{R}

Dirac field and gravity in NC $$SO(2,3)_\star $$ SO(2,3)⋆ model

European Physical Journal C: Particles and Fields, 2018
Action for the Dirac spinor field coupled to gravity on noncommutative (NC) Moyal-Weyl spacetime is obtained without prior knowledge of the metric tensor.

A remark on polar noncommutativity

Physics Letters B, 2015
Noncommutative space has been found to be of use in a number of different contexts. In particular, one may use noncommutative spacetime to generate quantised gravity theories.
