Technology development and the fast changing market have resulted in the life cycle of high-tech products becoming shorter. Enterprises must therefore continuously conduct innovative research to meet customer demand and increase industrial competitiveness. Innovative product research and management have become the most important activities in enterprise survival and sustainability. This study i...

In this paper, we analyze the outage probability of a multibranch selection combining (SC) based on the signal to interference ratio (SIR) over Weibull fading channels in case of non-identical power distribution per branches. Both, desired and interference signal envelopes are exponentially correlated Weibull random variables. Also, an analysis of effects of fading parameter β, correlation coef...

Capraria biflora L. is a shrub from the Scrophulariaceae family which produces in its roots a compound named biflorin, an o-naphthoquinone that shows activity against Gram-positive bacteria and fungi and also presents antitumor and antimetastatic activities. However, biflorin is hydrophobic and photosensitive. These properties make its application difficult. In this work we prepared biflorin mi...

4 A single-column modeling approach is proposed to study interaction between convection and 5 large-scale dynamics using the quasi-geostrophic (QG) framework. Vertical motion is repre6 sented by the QG omega equation with the diabatic heating term included. This approach 7 extends the notion of “parameterization of large scale dynamics”, previously applied in the 8 tropics using the weak temper...

INTRODUCTION Aim of our study is to evaluate the role of TWA to stratify the risk of sudden cardiac death in athletes (Ath) with complex ventricular arrhythmias (VA), and to document a possible correlation between TWA and electrophysiological testing (EES) results. METHODS We studied 43 Ath with VA (31 M, mean age 34 ± 12 years). In all cases a cardiological evaluation was performed, includin...
