Exposure within an environmental enrichment paradigm results in neurobiological adaptations and decreases the baseline of locomotor activity. The current study determined activation of DARPP-32 (dopamine- and cAMP-regulated phosphoprotein-32) and CREB (cAMP response element binding protein), and locomotor activity in rats raised in enriched (EC), impoverished (IC), and standard (SC) conditions ...

As a narrowband communication technology, long-range (LoRa) contributes to the long development of Internet Things (IoT) applications. The LoRa gateway plays an important role in IoT transport layer, and security efficiency are key issues current research. In centralized working model systems built by traditional gateways, all data generated reported end devices processed stored cloud servers, ...

Mobile edge computing (MEC) is a prominent paradigm which expands the application fields of wireless communication. Due to limitation capacities user equipments and MEC servers, caching (EC) optimization crucial effective utilization resources in MEC-enabled networks. However, dynamics complexities content popularities over space time as well privacy preservation users pose significant challeng...

This paper presents experimental results of a coverage analysis in a WCDMA network using the 850 MHz band; an urban electromagnetic propagation environment is considered. Obtained coverage estimation maps are based on Krige statistical method of interpolation. Key performance parameters used in this work are the CPICH and Ec. The results could be used to identify problems and help to optimize c...

Edge computing, as a new computing paradigm, brings cloud computing’s and storage capacities to network edge for providing low latency services users. The networked servers in specific area constitute edge systems (ESSs), where popular data can be stored serve the users area. novel ESSs raise many opportunities well unprecedented challenges. Most existing studies of focus on replicas sys...
