An extension of the Thomson principle [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
The classical Thomson principle, giving lower bounds for the Dirichlet integral, is extended, with modification, to a wider class of test functions. This makes it possible to obtain simpler and better lower bounds.

An Extension of the Invariance Principle for Switched Affine System

open access: yesTrends in Computational and Applied Mathematics, 2020
In this paper, an approach to investigate switched affine system via matrix inequalities is presented. Particularly, an extension of LaSalle’s invariance principle for this class of systems under arbitrary dwell-time switching signal is presented.

Equivalence Principle and Gravitational Redshift

open access: yes, 2011
We investigate leading order deviations from general relativity that violate the Einstein equivalence principle in the gravitational standard model extension. We show that redshift experiments based on matter waves and clock comparisons are equivalent to

On extension of Donsker–Prokhorov invariance principle

open access: yesLietuvos Matematikos Rinkinys, 2007
The extension of Donsker–Prokhorov invariance principle for two-dimensional parameter summation process in Hölder space is provided for the case of independent non-identically distributed random variables.

A complex singlet extension of the standard model and multi-critical point principle

open access: yesPhysics Letters B, 2023
We study the Multi-critical Point Principle (MPP) in a complex singlet scalar extension of the Standard Model (CxSM). The MPP discussed in this study selects model parameters so that two low-energy vacua realized by scalar fields are degenerate.

The prevention principle and the extension of time clauses in English law shipbuilding contracts

open access: yesPoredbeno Pomorsko Pravo, 2020
This paper deals with a well-established English law principle known as the “prevention principle“ in the context of shipbuilding contracts. Under the principle, no party to a contract should benefit from its own failure to perform.

A Variational Principle for the Asymptotic Speed of Fronts of the Density Dependent Diffusion--Reaction Equation

open access: yes, 1994
We show that the minimal speed for the existence of monotonic fronts of the equation $u_t = (u^m)_{xx} + f(u)$ with $f(0) = f(1) = 0$, $m >1$ and $f>0$ in $(0,1)$ derives from a variational principle.

About Extensions of the Extremal Principle

open access: yesVietnam Journal of Mathematics, 2018
In this article, after recalling and discussing the conventional extremality, local extremality, stationarity and approximate stationarity properties of collections of sets and the corresponding (extended) extremal principle, we focus on extensions of these properties and the corresponding dual conditions with the goal to refine the main arguments used

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 ...
