The Ins and Outs of Water in Olivine-Hosted Melt Inclusions: Hygrometer vs. Speedometer

open access: yesFrontiers in Earth Science, 2021
The amount of water dissolved in magmas at depth beneath volcanoes is fundamental to a wide range of magmatic and eruptive processes due to water’s dominant control on magma generation, viscosity, and buoyancy.

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.

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

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.

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.

On a time-dependent subdifferential evolution inclusion with a nonconvex upper-semicontinuous perturbation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2005
We investigate the existence of local approximate and strong solutions for a time-dependent subdifferential evolution inclusion with a nonconvex upper-semicontinuous perturbation.

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

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

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 ...
