Flat-band superconductivity in periodically strained graphene : mean-field and Berezinskii–Kosterlitz–Thouless transition

2020

In the search of high-temperature superconductivity one option is to focus on increasing the density of electronic states. Here we study both the normal and s-wave superconducting state properties of periodically strained graphene, which exhibits approximate flat bands with a high density of states, with the flatness tunable by the strain profile. We generalize earlier results regarding a one-dimensional harmonic strain to arbitrary periodic strain fields, and further extend the results by calculating the superfluid weight and the Berezinskii–Kosterlitz–Thouless (BKT) transition temperature T BKT to determine the true transition point. By numerically solving the self-consistency equation, w…

Influence of strain in the reduction of the internal electric field in GaN/AlN quantum dots grown ona-plane 6H-SiC

2006

The strain state of stacks of GaN/AIN quantum dots (QDs) grown on (0001) and (1120) 6H-SiC has been investigated by means of Raman spectroscopy. Depending on the orientation of the wurtzite axis with respect to the growth direction it is found that the piezoelectric contribution to the electrostatic potential may either reinforce that arising from the spontaneous polarization or oppose it. The experimental results are compared with a theoretical model for the strain and polarization field in QDs of both orientations that allows the calculation of the electrostatic potential in the QDs. Both the experimental results and the theoretical model indicate that the internal electric field and elec…

What is fitness training? Definitions and implications: A systematic review article

2015

Background: This review based upon studies searched from the major scientific libraries has the objective of clarifying what is fitness training in modern days, the implications that it has on health in both youth and elderly and finally discuss fitness training practical implications. Methods: The PRISMA statement was partially adopted and a number of 92 items were selected, according to the inclusion criteria. Results were discussed in 4 main sections: 1. Children and adolescents fitness levels; 2. Fitness training in the elderly; 3. Pathology prevention through fitness training; 4. Training through Fitness activities. Results: This review pointed out the fact that nowadays there is a lar…

L'evolució del conflicte de tasca, el conflicte de relació i el conflicte de procés en equips virtuals: el paper de l'entrenament

2010

L'objectiu d'aquest treball és estudiar els efectes de l'entrenament autoguiat en la percepció dels equips del conflicte de tasca, del conflicte de relació i del conflicte de procés, al llarg de tres sessions i en un context virtual. Per això es va fer un estudi de laboratori en el qual cinquanta-dos equips de comunicació sincrònica a través d'ordinador van treballar durant tres sessions: vint-i-set d'ells foren assignats a la condició experimental, en la qual van rebre un entrenament autoguiat, i la resta d'equips van ser assignats a la condició de control. Els resultats d'ANCOVA (anàlisi de covariància) de mesures repetides mostren que l'entrenament, junt amb l'experiència adquirida pels …

Short-term walking physical training and changes in body hydration status, B-type natriuretic peptide and C-reactive protein levels in compensated co…

2008

BACKGROUND: Congestive heart failure (CHF) is associated with decreased exercise tolerance, alterations in body fluid balance and activation of neurohumoral and inflammatory pathways. Physical training, despite the contraindications of the past, is recommended for its beneficial effects on exercise capacity and quality of life. We investigate the effects of a short-term (ten weeks) walking physical training program (PT) on body hydration state (HS), B-type natriuretic peptide (BNP) and C-reactive protein (CRP) levels. METHODS AND RESULTS: 22 patients with CHF (mean age 62.7+/-4.8 years, 15 men, mean ejection fraction 38.9+/-3.6%, NYHA class II-III), were enrolled. Eleven patients were rando…

Chebyshev’s Method on Projective Fluids

2020

We demonstrate the acceleration potential of the Chebyshev semi-iterative approach for fluid simulations in Projective Dynamics. The Chebyshev approach has been successfully tested for deformable bodies, where the dynamical system behaves relatively linearly, even though Projective Dynamics, in general, is fundamentally nonlinear. The results for more complex constraints, like fluids, with a particular nonlinear dynamical system, remained unknown so far. We follow a method describing particle-based fluids in Projective Dynamics while replacing the Conjugate Gradient solver with Chebyshev’s method. Our results show that Chebyshev’s method can be successfully applied to fluids and potentially…

Corticosteroids in oncology: Use, overuse, indications, contraindications. An Italian Association of Medical Oncology (AIOM)/ Italian Association of …

2022

Corticosteroids (CSs) are widely used in oncology, presenting several different indications. They are useful for induction of apoptosis in hematological neoplasms, for management of anaphylaxis and cytokine release/hypersensitivity reaction and for the symptomatic treatment of many tumour- and treatment-related complications. If the employment of CSs in the oncological setting results in several benefits for patients and satisfaction for clinicians, on the other hand, many potential adverse events (AEs), both during treatment and after withdrawal of CSs, as well as the duality of the effects of these compounds in oncology, recommend being cautious in clinical practice. To date, several gray…
