FIXED POINT - CRITICAL POINT HYBRID THEOREMS AND APPLICATION TO SYSTEMS WITH PARTIAL VARIATIONAL STRUCTURE

open access: yes, 2021
In this paper, fixed point arguments and a critical point technique are combined leading to hybrid existence results for a system of two operator equations where only one of the equations has a variational structure.

The longue duree of community engagement: New applications of critical theory in planning research [PDF]

open access: yes, 2013
Habermas' critical theory, and particularly his theory of communicative action, has been applied in the theory and practice of communicative planning. The concept of creating a public sphere in planning processes has been used as an ‘ought' that ...

On topological and metric critical point theory

open access: yes, 2010
Starting from the concept of Morse critical point, introduced by Ioffe and Schwartzman, we propose a possible approach to critical point theory for continuous functionals defined on topological spaces, which includes some classical results, also in an ...

A unified treatment using critical point methods of the existence of multiple solutions for superlinear and sublinear neumann problems

open access: yes, 2011
In this paper we present a framework which permits the unified treatment of the existence of multiple solutions for superlinear and sublinear Neumann problems. Using critical point theory, truncation techniques, the method of upper-lower solutions, Morse

Infinitely Many Periodic Solutions to Delay Differential Equations via Critical Point Theory

open access: yesAbstract and Applied Analysis, 2013
By the critical point theory, infinitely many 4σ-periodic solutions are obtained for the system of delay differential equations ẋt=-f(x(t-σ)), where σ∈(0,+∞) and f∈C(ℝn,ℝn).

Periodic Solutions for Semilinear Fourth-Order Differential Inclusions via Nonsmooth Critical Point Theory

open access: yesJournal of Function Spaces, 2014
Three periodic solutions with prescribed wavelength for a class of semilinear fourth-order differential inclusions are obtained by using a nonsmooth version critical point theorem. Some results of previous related literature are extended.

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective

open access: yesJournal of High Energy Physics, 2022
The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences are crucial for the ongoing experimental search for this critical point through the beam energy scan ...

Critical fluctuations and complex spinodal points [PDF]

open access: yes, 2018
The experimental signatures of the QCD critical point rely on the universal singular behavior of the equation of state at the critical point. Therefore, we study singularities of the universal scaling equation of state of the f4 theory, or the Ising ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Claudin‐6 Protein Expression in Atypical Teratoid/Rhabdoid Tumors Is Strongly Enriched in the Molecular Subgroup AT/RT‐TYR

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Claudin‐6 has emerged as a promising immunotherapeutic target, yet protein‐level data in atypical teratoid/rhabdoid tumors (AT/RTs) have been inconsistent. We analyzed 36 well‐characterized AT/RT samples and found membranous claudin‐6 protein expression in 58% of cases, with striking enrichment in the molecular subgroup AT/RT‐TYR (100%) and ...
