Sufficient conditions for the uniqueness of the maxima of the optimization problem in the framework of a stochastic model with priorities depending on one random variable [PDF]

open access: yesE3S Web of Conferences, 2020
An objective function arising in the optimization problem of a quasilinear complex system with dependent priorities is considered. In the case of three priorities based on the results of one experiment, sufficient conditions are obtained for all ...

A Platinum (II) Polyyne Oligomers Donor for Efficient Ternary Organic Solar Cells

open access: yesSolar RRL, EarlyView.
Platinum (II) polyyne oligomers P5 are used as a donor in a ternary organic solar cell. The average power conversion efficiency of 16% surpasses the international record for [Pt] (II) polyyne oligomers. PC71BM speeds up the rise time for electron transfer and slows down the recombination time.

On the classification of discrete Hirota-type equations in 3D [PDF]

open access: yes, 2013
In the series of recent publications we have proposed a novel approach to the classification of integrable differential/difference equations in 3D based on the requirement that hydrodynamic reductions of the corresponding dispersionless limits are ...

An existence result for a quasilinear system with gradient term under the Keller-Osserman conditions [PDF]

open access: yes, 2011
We use some new technical tools to obtain the existence of entire solutions for the quasilinear elliptic system of type D pui+hi(\vert x\vert) \vert \nabla ui\vert p-1=ai(\vert x\vert ) fi(u1,u2) on RN (N\geq 3, i=1,2) where N-1\geq p>1, Dp is the p ...

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys

open access: yessteel research international, EarlyView.
This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...

Simulation and theory for two-dimensional beam-plasma instability [PDF]

open access: yes
A comparative study of the dynamics of the electron beam-plasma system in two spatial dimensions is carried out by means of particle-in-cell (PIC) simulation and quasilinear theory.

Quasilinear evolution equations and parabolic systems [PDF]

open access: yesTransactions of the American Mathematical Society, 1986
It is shown that general quasilinear parabolic systems possess unique maximal classical solutions for sufficiently smooth initial values, provided the boundary conditions are “time-independent”. Moreover it is shown that, in the autonomous case, these equations generate local semiflows on appropriate Sobolev spaces. Our results apply, in particular, to
