On a second-order evolution inclusion [PDF]

open access: yesResults in Nonlinear Analysis, 2018
We study a class of second-order evolution inclusions and we obtain a sufficient condition for f-local controllability along a reference trajectory.

Microstructure and inclusion evolution in rare earth treated C-Mn steel

open access: yes工程科学学报, 2015
The microstructure and inclusions in rare earth treated C-Mn steel were studied,the size distribution of the nuclei inducing acicular ferrite nucleation was subjected to statistical analysis,and the formation and growth processes of rare earth inclusions

Scientist Spotlights: Online assignments to promote inclusion in Ecology and Evolution

open access: yesEcology and Evolution, 2020
Scientific disciplines face large diversity challenges, with the fields of ecology and evolution being among the most homogeneous—specifically with respect to race and ethnicity.

Effect of different strains on acicular ferrite and martensite-austenite islands in oxide metallurgy steel

open access: yesJournal of Materials Research and Technology, 2022
The microstructure transformation of oxide metallurgy steel was studied by deforming to strains of 0.1–1 at strain rates of 1 s−1 at 900 °C. The variation trends of AF laths and M-A islands size with increasing strain were investigated.

The Evolution of E-Inclusion [PDF]

open access: yes, 2004
The 1970s and 1980s saw a rapid take-up in the use of personal computers. During the same time period, society began to move towards providing equity for people with disabilities. As legislators around the world created new disability and Information Technology policies, more people with disabilities were given access to education and the evolving ...

Variational Analysis of Evolution Inclusions

open access: yesSIAM Journal on Optimization, 2007
The paper is devoted to optimization problems of the Bolza and Mayer types for evolution systems governed by nonconvex Lipschitzian differential inclusions in Banach spaces under endpoint constraints described by finitely many equalities and inequalities with generally nonsmooth functions. We develop a variational analysis of such problems mainly based

Nonlinear Delay Evolution Inclusions on Graphs [PDF]

open access: yes, 2014
We prove a necessary and a sufficient condition for a time-dependent closed set to be viable with respect to a delay evolution inclusion. An application to a null controllability problem is also included.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

On some differential inclusions with anti-periodic solutions

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we investigate a class of second- and first-order differential inclusions, along with an algebraic inclusion, all subject to anti-periodic boundary conditions in a real Hilbert space.

Strong nonlinear functional-differential variational inequalities: problems without initial conditions

open access: yesFrontiers in Applied Mathematics and Statistics
Problems without initial conditions for evolution equations and variational inequalities appear in the modeling of different non-stationary processes within many fields of science, such as ecology, economics, physics, cybernetics, etc., if these ...
