In the present study, we employed the dual task technique to explore the role of language in topographical working memory when landmarks are present along the path. We performed three experiments to mainly test the effects of language but also motor, spatial motor and spatial environment interferences on topographical working memory. We aimed to clarify both the role of language in navigational working memory per se and the extent to which spatial language interferes with the main task more than the other types of interference.

5G-specific features, such as massive deployment, heterogeneity, and coexistence, call for innovative dynamic spectrum management mechanisms. Context-aware interoperability and interference control, and their integration, may be crucial to comply with spectrum efficiency and service optimization 5G requirements.

We develop and study adaptive rate scheduling mechanisms over cellular wireless networks, as used for the unicast provision of video streams to client mobiles at variable quality of experience (QoE) levels. Under service type I, mobile users receive video streams at a QoE level that is not lower than a specified value. In addition, mobile users that experience sufficiently high communications channel quality levels, may be provided video streams at higher video quality levels.

This paper is an essay in micro-historical semantics and concerns the Late Latin verb charaxāre, a loanword from Gr. χαράξαι, χαράσσω. The scientific literature uses to separate two different semantic values of this Latin verb: ‘to carve; to cut’ and ‘to write’. In Herren’s opinion, starting from Virgilius Maro Grammaticus’ writings, charaxāre ‘to write’ was unique to Hisperic usage and derived from the knowledge of Greek glosses circulating among Irish monks from the VI-VII century AD onwards.

The ever-increasing number of vehicles on a global level signifies the need for communications between vehicles and the surrounding environment. Visible light communications (VLC) is a viable complementary technology to congested radio-frequency-based wireless systems.
