Weighted (p,q)-equations with gradient dependent reaction

open access: yesElectronic Journal of Differential Equations
We consider a weighted (p,q)-equation with a parametric reaction  depending on the gradient. Using truncation and comparison techniques  and the theory of nonlinear operators of monotone type, we show  that for all small values of the parameter, the problem has a  positive smooth solution.

Density-dependence tips the change of plant–plant interactions under environmental stress

open access: yesNature Communications, 2020
Density-dependence is rarely accounted for in plant-plant facilitation studies. Here the authors develop a framework that incorporates density-dependence in the stress-gradient hypothesis, and test it first through modeling and then empirically on ...

An isogeometric analysis approach to gradient‐dependent plasticity [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2017
SummaryGradient‐dependent plasticity can be used to achieve mesh‐objective results upon loss of well‐posedness of the initial/boundary value problem because of the introduction of strain softening, non‐associated flow, and geometric nonlinearity.

Dependence of bacterial chemotaxis on gradient shape and adaptation rate.

open access: yesPLoS Computational Biology, 2008
Simulation of cellular behavior on multiple scales requires models that are sufficiently detailed to capture central intracellular processes but at the same time enable the simulation of entire cell populations in a computationally cheap way.

Size-Dependent Behaviour of Representative Volume Element for Granular Material under Gravity-Induced Stress Gradient

open access: yesAdvances in Materials Science and Engineering, 2022
Gravity is the primary load source in geotechnical engineering, and its effect becomes extremely important in these cases such as lunar research station construction and in situ resource utilization. However, at the current stage, the study on the effect

On the Sub and Supersolution Method for Nonlinear Elliptic Equations with a Convective Term, in Orlicz Spaces

open access: yesMathematics
In this note we provide an overview of some existence (with sign information) and regularity results for differential equations, in which the method of sub and supersolutions plays an important role.

Protein synthesis dependent gradient of ECS retrograde amnesia [PDF]

open access: yesBehavioral Biology, 1977
The interacting amnesic effect of a protein synthesis inhibitor, anisomycin, and ECS was studied in active and passive avoidance tasks. By giving one to three injections of anisomycin, the duration of inhibition of protein synthesis was from 2 to 6 hr at 80% or greater.
