Left atrium function is essential for cardiovascular performance and is evaluable by two-dimensional speckle-tracking echocardiography (2D-STE). Our aim was to determine how echocardiographic parameters interrelate with exercise capacity and ventilatory efficiency in subjects with no structural heart disease. Asymptomatic volunteers, in sinus rhythm and(More)
This article presents a QoE-aware resource assignment and power allocation framework aiming at maximizing the minimum MOS of the users in a wireless network. It considers a satisfaction factor, that is, a requirement related to the minimum number of users that should be satisfied. This requirement is an important aspect from the operators' point of view and(More)
We investigated the involvement of protein kinase C (PKC) in the in vitro invasiveness of the A-172, U-87 and U-373 human glioma cell lines, as well as the role of ornithine decarboxylase (ODC) and/or extracellular-signal-regulated kinase (ERK) in the actions of PKC. Thus, cells were treated under serum-free conditions with the PKC activator phorbol(More)
The next generation of wireless telecommunications, 5G, is expected to have tight interworking between its novel air interface and legacy standards, such as the LTE. The major difference from interworking between previous RAT generations is that there will be common CN functionalities, enabling faster RAT scheduling due to reduced time spent with signaling.(More)
