Maximum entropy production principle in forest dynamics modelling [PDF]
Forest ecosystems are vivid representatives of open non-equilibrium systems. The existence of extreme principles in “ecological thermodynamics” is a subject of discussion in the works of many physicists, ecologists and researchers dealing with non ...

On the strong maximum principle for nonlocal operators [PDF]
In this paper we derive a strong maximum principle for weak supersolutions of nonlocal equations of the form $$\begin{aligned} Iu=c(x) u \qquad \text { in }\,\Omega , \end{aligned}$$Iu=c(x)uinΩ,where $$\Omega \subset \mathbb {R}^N$$Ω⊂RN is a domain, $$c ...

Some Inequalities for the Omori-Yau Maximum Principle
We generalize A. Borbély’s condition for the conclusion of the Omori-Yau maximum principle for the Laplace operator on a complete Riemannian manifold to a second-order linear semielliptic operator L with bounded coefficients and no zeroth order term ...

Lagrangian submanifolds generated by the Maximum Entropy principle
We show that the Maximum Entropy principle (E.T. Jaynes, [8]) has a natural description in terms of Morse Families of a Lagrangian submanifold. This geometric approach becomes useful when dealing with the M.E.P. with nonlinear constraints.

Application of maximum principle optimizing active current subharmonic filter [PDF]
In this article, the structure and parameters of an optimal regulator for active filter current subharmonics (AFSC) are received based on the optimal control method L. S. Pontryagin.

A maximum principle at infinity with applications to geometric vector fields
We derive a new form of maximum principle, applicable to a vector field with nonnegative divergence in a connected, oriented, complete noncompact Riemannian manifold. We then use it to obtain some applications to Killing vector fields. More precisely, we

Maximum principle for higher order operators in general domains
We first prove De Giorgi type level estimates for functions in W1,t(Ω), Ω⊂RN$ \Omega\subset{\mathbb R}^N $, with t>N≥2$ t \gt N\geq 2 $. This augmented integrability enables us to establish a new Harnack type inequality for functions which do not ...

On the maximum principle for a time-fractional diffusion equation [PDF]
In this paper, we discuss the maximum principle for a time-fractional diffusion equation ∂tαu(x,t)=∑i,j=1n∂i(aij(x)∂ju(x,t))+c(x)u(x,t)+F(x,t),t>0,x∈Ω⊂Rn,$$\begin{array}{} \displaystyle \partial_t^{\alpha} u(x,t) = \sum\limits_{i,j=1}^n \partial_i(a_{ij}(

ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.
