IEEE Access, 2018 The optimal power flow (OPF) model is a central optimization problem in power system network. In this paper, we propose a novel approach to solve the OPF problem that has a convex objective function and non-convex feasible domain due to the constraints ...

New integral inequalities via $(α,m)$-convexity and quasi-convexity [PDF]
arXiv, 2012 In this paper, we establish some new integral inequalities for $(\alpha, m)-$convex functions and quasi-convex functions, respectively. Our results in special cases recapture known results.

Advanced Materials Interfaces, EarlyView.CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

A characterization of convex function
Applied Mathematics Letters, 2000 AbstractIf C ⊆ Rn be a nonempty convex set, then f: C → R is convex function if and only if it is a quasiconvex function on C and there exists some α ∈ (0, 1) such that f(ax+1(1−α)y)≤αf(x)+(1−α)f(y), ∀x,y ϵC.

A Note on Optimality Conditions for DC Programs Involving Composite Functions
Abstract and Applied Analysis, 2014 By using the formula of the ε-subdifferential for the sum of a convex function with a composition of convex functions, some necessary and sufficient optimality conditions for a DC programming problem involving a composite function are obtained.

Convex-transitivity and function spaces [PDF]
arXiv, 2007 If X is a convex-transitive Banach space and 1\leq p\leq \infty then the closed linear span of the simple functions in the Bochner space L^{p}([0,1],X) is convex-transitive. If H is an infinite-dimensional Hilbert space and C_{0}(L) is convex-transitive, then C_{0}(L,H) is convex-transitive. Some new fairly concrete examples of convex-transitive spaces
