However, novel architectures are required to enable cost-efficient deployments of very dense outdoor Small Cell networks, complementing the coverage layer provided by macro-cells. In this regard, two important challenges need to be solved to make this vision a reality: i) increased traffic dynamics, which are translated into more frequent handovers, and ii) cost-efficient deployment of large number of Small Cells. In this paper we propose and evaluate SENSEFUL, an novel architecture addressing the two problems highlighted above: Software-Defined Networking (SDN) as the key technology to promote adaptability to a varying environment and provide efficient mobility solutions in the dense access layer, and novel wireless backhauling technologies where traditional wired connectivity does not meet cost/efficiency restrictions.Postprint (author's final draft

Triggering forces at the nanoscale: Technologies for single-chain mechanical activation and manipulation

Over the past decades, polymer mechanochemistry has focused on the development and application of advanced force application methods to better understand the mechanochemical response of mechanophores. In this regard, techniques such as ultrasonication and single-molecule force spectroscopy (SMFS) are used to activate and detect up to thousands of chemical events within a polymer single chain, allowing the researchers to probe the mechanochemical reactivity of these stress-responsive motifs. Here, the most recent contributions of the single-molecule force spectroscopy technique to this field are presented, putting emphasis on the fundamental parameters of the technique for triggering specific force responses and on the description of force–extension curves measured for single- and multi-mechanophore polymers. Moreover, new contributions of microscopy-based techniques in the field of polymer mechanochemistry, as well as the potential application of single-chain nanoparticles as mechanoresponsive materials, are highlighted.J.A.P and E.V.-S gratefully acknowledge funding by Gipuzkoako Foru Aldundia-Programa Red Gipuzkoana de Ciencia, Tecnología e Innovación 2019 (Grant No. 2019-CIEN-000050-01); Basque Government (Grant No. IT-1175-19); and MCIU/AEI/FEDER, UE (Grant No. PGC2018-094548-B-I00).

Perla Quirúrgica: Surco mento labial y región mentoniana Consideraciones clínicas y anatomía quirúrgica

La región mentoniana es una unidad regional estática compuesta por los músculos depresores del labio y el músculo mentoniano. Los músculos depresores del labio están compuestos por el depresor del labio inferior y los músculos depresores del ángulo oral. El músculo mentoniano es el que protruye el labio inferior. Todos están inervados por la rama marginal mandibular del nervio facial y por la rama sensitiva del nervio mentoniano originado de la división mandibular del nervio trigémino. Este último nervio sale del agujero mentoniano y puede ser bloqueado fácilmente percutáneo o intraoral
