Extensions and improvements of Sherman’s and related inequalities for n-convex functions
Open Mathematics, 2017 This paper gives extensions and improvements of Sherman’s inequality for n-convex functions obtained by using new identities which involve Green’s functions and Fink’s identity.

Convexity and potential sums for Salpeter-like Hamiltonians
, 2002 The semirelativistic Hamiltonian H = \beta\sqrt{m^2 + p^2} + V(r), where V(r) is a central potential in R^3, is concave in p^2 and convex in p. This fact enables us to obtain complementary energy bounds for the discrete spectrum of H.

Generalization of cyclic refinements of Jensen’s inequality by Fink’s identity
, 2018 We generalize cyclic refinements of Jensen’s inequality from a convex function to a higher-order convex function by means of Lagrange–Green’s function and Fink’s identity.

Socioeconomic impact on quality of care in pelvic gynecological cancers
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Introduction Several European studies have shown health‐related social inequalities in pelvic gynecological cancers, with a social gradient in incidence and mortality, partly explained by more advanced stages at diagnosis in low socioeconomic populations.

Discontinuous gradient constraints and the infinity Laplacian [PDF]
, 2012 Motivated by tug-of-war games and asymptotic analysis of certain variational problems, we consider a gradient constraint problem involving the infinity Laplace operator.

Wind Energy Science, 2019 . Wind power is a variable generation resource and therefore requires accurate forecasts to enable integration into the electric grid. Generally, the wind speed is forecast for a wind plant and the forecasted wind speed is converted to power to provide ...

CSR disclosure and investment efficiency in MENA countries: The moderating role of CSR committee
Strategic Change, EarlyView.ABSTRACT Corporate social responsibility disclosure (CSRD) is often recognized as a transparency mechanism that allows companies to communicate their commitment to CSR. However, CSRD may also exacerbate agency conflicts. This study addresses these two contrasting perspectives by investigating the impact of CSRD on investment efficiency and exploring ...

On the Jensen functional and superquadraticity
, 2015 In this note we give a recipe which describes upper and lower bounds for the Jensen functional under superquadraticity conditions. Some results involve the Chebychev functional.

Expected Profitability of Capital under Uncertainty – a Microeconomic Perspective [PDF]
Hartman (1972) and Abel (1983) showed that when firms are competitive and there is flexibility of labour relative to capital, marginal profitability of capital is a convex function of the stochastic variable (e.g., price); by Jensen’s inequality, this ...

, 2011 We survey several significant results on the Bohr inequality and presented its generalizations in some new approaches. These are some Bohr type inequalities of Hilbert space operators related to the matrix order and the Jensen inequality.
