Background: To determine the efficacy of different antiseptic solutions (Control group (I), Antibiotic solution (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in sterilizing contaminated osteochondral plugs. Methods: Under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. A total of 200 osteochondral specimens...

The universal approximation property is an important characteristic of models employed in the solution of machine learning problems. The possibility of approximating within a desired precision any Borel measurable function guarantees the generality of the considered approach. The properties of the class of positive Boolean functions, realizable by digital circuits containing only and and or por...

Improperly efficient solutions in the sense of Geoffrion linear fractional vector optimization problems with unbounded constraint sets are studied systematically for first time this paper. We give two conditions which assure that all a given problem improperly efficient. also obtain necessary an solution to be As result, we have new sufficient Geoffrion’s proper efficiency. The obtained results...

In this paper we propose a new numerically reliable computational approach to determine the inner-outer factorization of a rational transfer matrix G of a linear descriptor system. In contrast to existing computationally involved “one-shot” methods which require the solution of Riccati or generalized Riccati equations, the new approach relies on an efficient recursive zeros dislocation techniqu...

In this work we characterize different types of solutions of a vector optimization problem by means of a scalarization procedure. Usually different scalarizing functions are used in order to obtain the various solutions of the vector problem. Here we consider different kinds of solutions of the same scalarized problem. Our results allow us to establish a parallelism between the solutions of the...

This article concerns the stability and periodicity of solutions to the delay dynamic system x4(t) = A(t)x(t) + F (t, x(t), x(g(t))) + C(t) on a time scale. By the inequality technique for vectors, we obtain some stability criteria for the above system. Then, using the Horn fixed point theorem, we present some conditions under which our system is asymptotically periodic and its periodic solutio...

Abstract: This paper focuses on the efficient solution of models defined in high dimensional spaces. Those models involve numerous numerical challenges because of their associated curse of dimensionality. It is well known that in meshbased discrete models the complexity (degrees of freedom) scales exponentially with the dimension of the space. Many models encountered in computational science an...
