Spatial modulation (SM) is a particularly important form of multiple-input multiple-output (MIMO), which uses both symbols and antenna indices to carry information. In this paper, avoid the high cost circuit complexity SM, we consider hybrid SM system with precoding transmitter architecture, combining digital precoder an analog precoder. such system, carried out secure transmit subarray selecti...

Attribute selection is one of the important problems encountered in pattern recognition, machine learning, data mining, and bioinformatics. It refers to the problem of selecting those input attributes or features that are most effective to predict the sample categories. In this regard, rough set theory has been shown to be successful for selecting relevant and nonredundant attributes from a giv...

this study was designed to investigate the effects of tangerine, orange, and grapefruit juice on the pharmacokinetic pattern of cyclosporine a in rats. forty male sprague-dawley rats were divided into four groups to receive water, orange, tangerine, or grapefruit juices respectively. water or juices (10 ml/kg) were given orally twice a day for 3 days. three hours after the 5 th dose, cyclospori...

Inthis paper, the main aim is to introduce the class $mathcal{U}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings togetherwith its subclasses $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ and $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p^0$, andinvestigate the properties of the mappings in these classes. First,we give a sufficient condition for mappings to be in $mathcal{U}_p(l...

In this paper we propose the use of two resolution-based rules for the Max-SAT encoding of the Maximum Clique Problem. These rules simplify the problem instance in such a way that a lower bound of the optimum becomes explicit. Then, we present a pre-processing procedure that applies such rules. Empirical results show evidence that the lower bound obtained with the preprocessing outperforms prev...

      The pharmacokinetic properties of amoxicillin and clavulanic acid when used alone or in combination may be different and show interaction between these two agents that might decrease the absolute bioavailability of clavulanic acid. In an open, randomized, replicated Latin square under fasting condition, pharmacokinetics of new formulations of amoxicillin/clavulanic acid were compared with...
