Asymptotic Behaviors of Solutions to quasilinear elliptic Equations with critical Sobolev growth and Hardy potential

2015

Abstract Optimal estimates on the asymptotic behaviors of weak solutions both at the origin and at the infinity are obtained to the following quasilinear elliptic equations − Δ p u − μ | x | p | u | p − 2 u = Q ( x ) | u | N p N − p − 2 u , x ∈ R N , where 1 p N , 0 ≤ μ ( ( N − p ) / p ) p and Q ∈ L ∞ ( R N ) .

On a time-depending Monge-Ampère type equation

2012

Abstract In this paper, we prove a comparison result between a solution u ( x , t ) , x ∈ Ω ⊂ R 2 , t ∈ ( 0 , T ) , of a time depending equation involving the Monge–Ampere operator in the plane and the solution of a conveniently symmetrized parabolic equation. To this aim, we prove a derivation formula for the integral of a smooth function g ( x , t ) over sublevel sets of u , { x ∈ Ω : u ( x , t ) ϑ } , ϑ ∈ R , having the same perimeter in R 2 .

New degeneration of Fay's identity and its application to integrable systems

2011

In this paper, we find a new degenerated version of Fay's trisecant identity; this degeneration corresponds to the limit when the four points entering the trisecant identity coincide pairwise. This degenerated version of Fay's identity is used to construct algebro-geometric solutions to the multi-component nonlinear Schrodinger equation. This identity also leads to an independent derivation of algebro-geometric solutions to the Davey–Stewartson equations previously obtained in [17] in the framework of the Krichever scheme. We also give the condition of smoothness of the obtained solutions.

Quality of Life and Sexuality among People with Mental and Physical Disabilities in the Italian Context

2016

Aim: The article analyses sexuality and quality of life among people with mental and physical disabilities in the Italian context. It is aimed at contributing to a social debate over the sexual assistant for disabled people, as this professional is not still present in Italy. The aim of this paper is therefore to reflect on the consequences of the negative attitudes towards sexual life in disabled people, as well as for their families and community. In the collective unconscious, people with physical or mental disabilities are considered unable to live a healthy sexuality. This representation contributes to the spread of false attributions and prejudices. These characteristics may also be f…

Cross-cultural adaptation and test-retest reliability of the spanish ROWAN foot pain assessment questionnaire (ROFPAQ-S)

2020

Background The ROWAN Foot Pain Assessment Questionnaire (ROFPAQ) may be considered as a self-reported health questionnaire with 45 items to measure foot health problems such as foot pain. To date, the ROFPAQ has only been validated into an English-language version. Objectives Therefore this study aim was to perform the cross-cultural adaptation and test-retest reliability of the Spanish ROFPAQ version (ROFPAQ-S). Study design A cross-sectional descriptive study. Settings Podiatry and physiotherapy clinical centers. Methods The recommended forward/backward translation protocol was applied for the procedure of translation and cross-cultural adaptation from United Kingdom to Spain. Results An …

Four-quark stability

2009

The physics of charm has become one of the best laboratories exposing the limitations of the naive constituent quark model and also giving hints into a more mature description of meson spectroscopy, beyond the simple quark--antiquark configurations. In this talk we review some recent studies of multiquark components in the charm sector and discuss in particular exotic and non-exotic four-quark systems, both with pairwise and many-body forces.

Cross-cultural adaptation and validation of the French version of the Knee injury and Osteoarthritis Outcome Score (KOOS) in knee osteoarthritis pati…

2008

Udgivelsesdato: 2008-Apr OBJECTIVE: To adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) into French and to evaluate the psychometric properties of this new version. METHODS: The French version of the KOOS was developed according to cross-cultural guidelines by using the "translation-back translation" method to ensure content validity. KOOS data were then obtained in patients with symptomatic knee osteoarthritis (OA). The translated questionnaire was evaluated in two knee OA population groups, one with no indication for joint replacement (medicine), and the other waiting for joint replacement (surgery). The psychometric properties evaluated were feasibility: percentage of respon…

The Relationship between Risk-Taking, Sensation-Seeking, and the Tourist Behavior of Young Adults: A Cross-Cultural Study

2004

This study analyzed the effects of the combined psychological characteristics of risk-taking and sensation seeking on the travel behavior and preferred tourist activities of young adults on leisure trips. The results of this cross-cultural study, which was conducted among 1,429 students at 11 universities located in 11 different countries, found that respondents with high combined risk-taking and sensation seeking (RSS) scores differed significantly in their travel behavior, mode of destination choice, preferred tourist activities and demographics, from those who had low RSS scores. The study also discovered a significant difference between nationalities on RSS scores.

Measuring and Evaluating Intergenerational Mobility: Evidence from Students’ Questionnaires

2005

Three fundamental ideas in the study of intergenerational mobility are those of structural mobility, origin independence and rank reversal. We review the theoretical literature focused on the three ideas and present evidence from a questionnaire designed to test students’ views regarding the different notions. The questionnaire is conducted under both a “measurement” and an “evaluation” frame; it uses questions involving both verbal statements of the principles tested and pairwise comparisons of simple hypothetical mobility situations; for the latter exercise, the questionnaire introduces a new intuitive display based on mobility trees. The evidence provides various results: most notably, o…
