Hyperpositive non-linear effects: enantiodivergence and modelling

open access: yesChemical Science, 2020
An asymmetric reaction consisting of competing monomeric and dimeric catalysts may explain enantiodivergent non-linear effects.

Modelling non-linear effects of dark energy [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2018
We investigate the capabilities of perturbation theory in capturing non-linear effects of dark energy. We test constant and evolving $ω$ models, as well as models involving momentum exchange between dark energy and dark matter. Specifically, we compare perturbative predictions at 1-loop level against N-body results for four non-standard equations of ...

EFFECT OF VARYING AIRGAP LENGTH ON PERFORMANCE OF LINEAR AND NON LINEAR ELECTROMECHANICAL

open access: yesAl-Qadisiyah Journal for Engineering Science, 2009
This work studies the effect of varying air-gap length on performance and behavior of electromechanical relays. When the air-gap length changed due to mechanical movement producing from air or liquid pressure in pneumatic or hydraulic system ...

Parity-time symmetry with coherent atomic gases

open access: yesAdvances in Physics: X, 2017
In standard quantum theory, the Hamiltonian describing a physical system is assumed to be Hermitian in order to guarantee the energy spectrum to be real and the time evolution to be unitary.

Investigating the effect of the middle soft layer on the equivalent-linear and non-linear dynamic site responses [PDF]

open access: yesمدل‌سازی پیشرفته در مهندسی عمران
In this paper, the effect of the middle soft soil layer on the seismic response of a multi-layered site is investigated with the help of one-dimensional equivalent-linear and non-linear analysis methods.

Quantum metric non-linear Hall effect in an antiferromagnetic topological insulator thin-film EuSn2As2

open access: yesMaterials Today Quantum
The quantum geometric structure of electrons introduces fundamental insights into understanding quantum effects in materials. One notable manifestation is the non-linear Hall effect (NLHE), which has drawn considerable interest for its potential to ...

Positive solutions for 3X3 elliptic bi-variate infinite semipositone systems with combined nonlinear effects

open access: yesElectronic Journal of Differential Equations, 2016
We study the existence of positive solutions to 3X3 bi-variate systems of reaction diffusion equations with Dirichlet boundary conditions. In particular, we consider systems where the reaction terms approach -infinity near the origin and satisfy some

Non-linear relationship between triglyceride glucose-body mass index and risk of diabetes in adults: a general population-based cohort study of Chinese adults using a publicly available DRYAD dataset

open access: yesFrontiers in Endocrinology
ObjectiveDespite triglyceride glucose-body mass index (TyG-BMI) being a validated marker of insulin resistance, its prospective association with diabetes risk remains unclear; we therefore examined the impact of TyG-BMI on incident diabetes.MethodsThis ...

Impact scores of invasive plants are biased by disregard of environmental co-variation and non-linearity

open access: yesNeoBiota, 2011
Prioritisation of high-impact species is becoming increasingly important for management of introduced species (‘neobiota’) because of their growing number of which, however, only a small fraction has substantial impacts.
