MathematicsIn 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.

, 2018 We consider a nonlinear elliptic problem driven by the Dirichlet p-Laplacian and a reaction term which depends also on the gradient (convection). No growth condition is imposed on the reaction term f (z, ·, y).

AMBER/VLTI observations of the B[e] star MWC 300 [PDF]
, 2012 Aims. We study the enigmatic B[e] star MWC 300 to investigate its disk and binary with milli-arcsecond-scale angular resolution. Methods. We observed MWC 300 with the VLTI/AMBER instrument in the H and K bands and compared these observations with ...

THE ABUNDANCE OF HELIUM AND STELLAR PULSATION
Odessa Astronomical Publications, 2017 Radial gradient of relative amplitude of the light variation FV for galactic classical Cepheids is found. The gradient has different signs for two cases: P > 8d and P < 8d. For P > 8d the gradient is negative.

Strain-gradient elasticity and gradient-dependent plasticity with hierarchical refinement of NURBS [PDF]
Finite Elements in Analysis and Design, 2019 Higher-order strain-gradient models are relevant for engineering materials which exhibit size-dependent behaviour as observed from experiments. Typically, this class of models incorporate a length scale - related to micro-mechanical material properties - to capture size effects, remove stress singularities, or regularise an ill-posed boundary value ...

Cross-shelf eddy heat transport in a wind-free coastal ocean undergoing winter time cooling [PDF]
, 2001 A steady state cross-shelf density gradient of a wind-free coastal ocean undergoing winter time cooling is found for cooling and geometries which do not vary in the along-shelf direction. The steady state cross-shelf density gradient exists even when the

Scale dependence of canopy trait distributions along a tropical forest elevation gradient.
New Phytologist, 2017 Average responses of forest foliar traits to elevation are well understood, but far less is known about trait distributional responses to elevation at multiple ecological scales.

Dynamical Systems Approach of Internal Length in Fractional Calculus
Engineering Transactions, 2017 Conventionally, non-local properties are included in the constitutive equations in the form of strain gradient-dependent terms. In case of the second gradient dependence an internal material length can be obtained from the critical eigenmodes in ...

Proton Gradients and Proton-Dependent Transport Processes in the Chloroplast [PDF]
Frontiers in Plant Science, 2016 Proton gradients are fundamental to chloroplast function. Across thylakoid membranes, the light induced -proton gradient is essential for ATP synthesis. As a result of proton pumping into the thylakoid lumen, an alkaline stromal pH develops, which is required for full activation of pH-dependent Calvin Benson cycle enzymes.

Impurity transport in temperature gradient driven turbulence [PDF]
, 2011 In the present paper the transport of impurities driven by trapped electron (TE) mode turbulence is studied. Non-linear (NL) gyrokinetic simulations using the code GENE are compared with results from quasilinear (QL) gyrokinetic simulations and a ...
