Second-Order Dynamic Equations with Noncanonical Operator: Oscillatory Behavior

open access: yesFractal and Fractional, 2023
The present article aims to study the oscillatory properties of a class of second-order dynamic equations on time scales. We consider during this study the noncanonical case, which did not receive much attention compared to the canonical dynamic ...

One-loop effective action in the case of noncanonical gauge kinetic energy [PDF]

open access: yesPhysical Review D, 1992
We calculate the one-loop effective action for a four-dimensional bosonic model when the gauge kinetic energy and F-F-dual terms are coupled to the scalar fields.

Improved Properties of Positive Solutions of Higher Order Differential Equations and Their Applications in Oscillation Theory

open access: yesMathematics, 2023
In this article, we present new criteria for testing the oscillation of solutions of higher-order neutral delay differential equation. By deriving new monotonic properties of a class of the positive solutions of the studied equation, we establish better ...

Simplified and improved criteria for oscillation of delay differential equations of fourth order

open access: yesAdvances in Difference Equations, 2021
An interesting point in studying the oscillatory behavior of solutions of delay differential equations is the abbreviation of the conditions that ensure the oscillation of all solutions, especially when studying the noncanonical case.

Asymptotic behavior of even-order noncanonical neutral differential equations

open access: yesDemonstratio Mathematica, 2022
In this article, we study the asymptotic behavior of even-order neutral delay differential equation (a⋅(u+ρ⋅u∘τ)(n−1))′(ℓ)+h(ℓ)u(g(ℓ))=0,ℓ≥ℓ0,{(a\cdot {(u+\rho \cdot u\circ \tau )}^{(n-1)})}^{^{\prime} }(\ell )+h(\ell )u(g(\ell ))=0,\hspace{1.0em}\ell ...

New oscillation constraints for even-order delay differential equations [PDF]

open access: yesOpuscula Mathematica, 2023
The purpose of this paper is to study the oscillatory properties of solutions to a class of delay differential equations of even order. We focus on criteria that exclude decreasing positive solutions.

bτUnification and Large Atmospheric Mixing: A Case for a Noncanonical Seesaw Mechanism [PDF]

open access: yesPhysical Review Letters, 2003
We study the second and third generation masses in the context of the minimal renormalizable SO(10) theory. We show that if the seesaw takes the noncanonical (type II) form, large atmospheric neutrino mixing angle requires b-tau unification.

Mycobacterium tuberculosis Keto-Mycolic Acid and Macrophage Nuclear Receptor TR4 Modulate Foamy Biogenesis in Granulomas: A Case of a Heterologous and Noncanonical Ligand-Receptor Pair [PDF]

open access: yesThe Journal of Immunology, 2014
Abstract The cell wall of Mycobacterium tuberculosis is configured of bioactive lipid classes that are essential for virulence and potentially involved in the formation of foamy macrophages (FMs) and granulomas. Our recent work established crosstalk between M. tuberculosis cell wall lipids and the host lipid-sensing nuclear receptor TR4.
