Can the integration of agriculture and tourism foster agricultural green development? An empirical analysis based on panel data from 30 provinces in China

Frontiers in Sustainable Food Systems
The integration of agriculture and tourism, grounded in agricultural resources, not only offers new development opportunities for the agricultural sector but also steers it towards a greener and more sustainable trajectory.

Controlling ultrafast currents by the non-linear photogalvanic effect

, 2015
We theoretically investigate the effect of broken inversion symmetry on the generation and control of ultrafast currents in a transparent dielectric (SiO2) by strong femto-second optical laser pulses. Ab-initio simulations based on time-dependent density

Non-linear effects in electron cyclotron current drive applied for the stabilization of neoclassical tearing modes [PDF]

, 2014
Due to the smallness of the volumes associated with the flux surfaces around the O-point of a magnetic island, the electron cyclotron power density applied inside the island for the stabilization of neoclassical tearing modes (NTMs) can exceed the ...

Comparing Coefficients of Nonlinear Multivariate Regression Models Between Equations

Survey Research Methods, 2015
The present study discusses the usage of non-linear constraints in regression models with multiple categorical outcomes. With this approach, effect differences between equations are made accessible to statistical tests while potential differences in ...

Non-linear effect of uniaxial pressure on superconductivity in CeCoIn5

, 2011
We study single-crystal CeCoIn5 with uniaxial pressure up to 3.97 kbar applied along the c-axis. We find a non-linear dependence of the superconducting transition temperature Tc on pressure, with a maximum close to 2 kbar.

Regional divergence in the urban form-carbon emission nexus: a comparative analysis of linear and non-linear spatial modeling approaches for 286 Chinese cities

Frontiers in Environmental Science
Urban areas account for over 70% of global CO2 emissions. Recent studies show that urban morphology’s impact on carbon emissions is more complex than traditional linear models suggest, with critical implications for low-carbon urban planning in China ...

Non linear thermal radiation effect on Williamson fluid with particle-liquid suspension past a stretching surface

Results in Physics, 2017
A mathematical analysis of two-phase boundary layer flow and heat transfer of a Williamson fluid with fluid particle suspension over a stretching sheet has been carried out in this paper.

Nonlinear Effects Induced by Interactions among Functional Groups of Bacteria and Fungi Regulate the Priming Effect in Malagasy Soils

Microorganisms, 2023
The priming effect (PE) occurs when fresh organic matter (FOM) supplied to soil alters the rate of decomposition of older soil organic matter (SOM).

Hyperpositive non-linear effects: enantiodivergence and modelling

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

Power Spectrum Correlations Induced by Non-Linear Clustering [PDF]

, 1999
Gravitational clustering is an intrinsically non-linear process that generates significant non-Gaussian signatures in the density field. We consider how these affect power spectrum determinations from galaxy and weak-lensing surveys. Non-Gaussian effects
