In this work, Ni-doped lead-free ferroelectric Ba(Ti0.8Zr0.2)O3 materials were well synthesized by a simple chemical route. The complex magnetic behavior of the materials was explained by the random distribution of Ni cations into the Ba(Ti0.8Zr0.2)O

Combination in both ferroic properties in current lead-free ferroelectric materials is promising in creating a new type of smart electronic devices. In this report, single perovskite Co-doped 0.2BaZrO3-0.8BaTiO3 materials were synthesized by using th

Mangroves are tropical/subtropical communities of tree species that grow in the estuary areas, in intertidal mudflats and along coastlines, where they are regularly inundated by saline or brackishwater. Living at the interface between land and sea, m

In this article we develop conditions for feasible points to be global minimizers of nonlinear programming problems with bounds on the variables. We obtain sufficient conditions for global optimality, first by constructing quadratic underestimators o

The celebrated S-lemma establishes a powerful equivalent condition for the nonnegativity of a quadratic function over a single quadratic inequality. However, this lemma fails without the technical condition, known as the Slater condition. In this pap

In the present paper we prove that, under some suitable conditions on multifunctions $C\!: {I\!\!R}^l\rightrightarrows {I\!\!R}^n$ , $F\!:{I\!\!R}^d\times {I\!\!R}^n\rightrightarrows {I\!\!R}^m$ , and $K\!:{I\!\!R}^l\times {I\!\!R}^n\rightrightarrows
