VNF Placement for Service Function Chains with Strong Low-Delay Restrictions in Edge Computing Networks

Applied Sciences, 2020
The edge computing paradigm, allowing the location of network services close to end users, defines new network scenarios. One of them considers the existence of micro data centers, with reduced resources but located closer to service requesters, to ...

Impact of CoMP VNF placement on 5G Coordinated Scheduling performance [PDF]

2017 European Conference on Networks and Communications (EuCNC), 2017
To address demanding requirements in terms of expected throughput, latency and scalability, 5G networks will offer high capacity to support huge volumes of traffic generated by heterogeneous services. Dense deployment of small cells can provide a valid solution but are prone to high levels of interference especially at the cell-edge. However, to reduce

GLP‐1 Receptor Agonists for the Prevention of New‐Onset Heart Failure: A Systematic Review and Meta‐Analysis of Placebo‐Controlled Randomized Clinical Trials

Obesity Reviews, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA) improve outcomes in heart failure (HF) with preserved ejection fraction. Whether GLP‐1 RA prevent new‐onset HF in Type 2 diabetes or obesity requires further investigation. Methods We performed an updated meta‐analysis of randomized placebo‐controlled trials (RCT) of treatment ...
