Moduli of continuity for viscosity solutions [PDF]

open access: yesProceedings of the American Mathematical Society, 2015
In this paper, we investigate the moduli of continuity for viscosity solutions of a wide class of nonsingular quasilinear evolution equations and also for the level set mean curvature flow, which is an example of singular degenerate equations. We prove that the modulus of continuity is a viscosity subsolution of some one dimensional equation. This work

Characteristic of the Pressurized Continuous Bunsen Reaction using HIx Solution

open access: yesMATEC Web of Conferences, 2016
The Sulfur-Iodine thermochemical hydrogen production process (SI process) consists of the Bunsen reaction section, the H2SO4 decomposition section and the HI decomposition section. The HIx solution (HI-I2-H2O) could be recycled to Bunsen reaction section

Modulus of continuity of the Dirichlet solutions [PDF]

open access: yesBulletin of the London Mathematical Society, 2010
Let D be a bounded domain in Rn with n >= 2. For a function f on ∂D we denote by HDf the Dirichlet solution of f over D. It is classical that if D is regular, then HD maps the family of continuous boundary functions to the family of harmonic functions in D continuous up to the boundary ∂D.

Continuity of bargaining solutions [PDF]

open access: yesInternational Journal of Game Theory, 1983
Upper semicontinuous solutions of the bargaining problem are studied and also lower semicontinuous weak solutions of that problem are considered. Though mainly compact bargaining pairs are investigated, extensions to non-compact bargaining pairs are indicated. The continuity properties of some well known bargaining solutions are discussed.

Continuous Lithium Extraction from Aqueous Solution Using Flow-Electrode Capacitive Deionization

open access: yesEnergies, 2019
Flow-electrode-based capacitive deionization (FCDI) is a desalination process that uses electrostatic adsorption and desorption of ions onto electrode materials. It provides a continuous desalination flow with high salt removal performance and low energy

Refined Upper Solution Bound of the Continuous Coupled Algebraic Riccati Equation

open access: yesComplexity, 2020
The continuous coupled algebraic Riccati equation (CCARE) has wide applications in control theory and linear systems. In this paper, by a constructed positive semidefinite matrix, matrix inequalities, and matrix eigenvalue inequalities, we propose a new ...

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.
