Operator Revenue Analysis for Device-to-Device Communications Overlaying Cellular Network
2018
Device-to-device (D2D) communications has recently gathered significant research interest due to its efficient utilization of already depleting wireless spectrum. In this article, we considered a scenario where D2D users communicate in the presence of cellular users in an overlay network setup. In order to analyze the revenue of service providers in monetary terms, the paper provides exact expressions of operator profit for both D2D and cellular users. More specifically, we take into account different network parameters including user density, transmit power and channel variations to understand their impact on the total revenue of the operator. Finally, we derive the balancing value of freq…
Multi-hop D2D Communications with Network Coding : From A Performance Perspective
2019
Multi-hop device-to-device (D2D) communications play an important role in expanding D2D coverage. In this paper, we study a relay-based and network-coding-assisted (in particular, XOR coding) multi-hop D2D communication system. In the system, toward jointly considering the impact of interference and network traffic conditions on the quality of D2D communications, various channel fading models and traffic models are investigated, and the packet loss probability of D2D links is meticulously computed using these models. With the packet loss probability of D2D links, the general closed-form expressions of end-to-end packet loss probability (E2EPLP) of the system with the presence (or absence) o…
Mesure de la performance des agences bancaires par une approche DEA
2005
Using a DEA framework (Data Envelopment Analysis), we develop new performance indicators for integrated retail networks. A methodological discussion leads us to propose a productivity indicator which respects the criteria of controllability and transversal coherence. We then formalise the relationship between a performance indicator of a network's headquarters and the productivity of its various retailers. Finally, we combine these new indicators in crafting a management tool amenable to a system of balanced scorecards.
“La tonadilla a la Barcelona del darrer terç del Set-cents més enllà de la Casa de Comèdies"
2014
Resum: Encara que el monopoli oficial dels espectacles teatrals a la Barcelona del Set-cents era en mans de l’Hospital de la Santa Creu, és sabut que l’afició dels barcelonins pel teatre anava més enllà de la Casa de Comèdies gestionada per aquesta entitat. En el present article es mostren diversos casos que manifesten l’interès del públic barceloní per la tonadilla, gènere lírico-escènic breu importat a la Ciutat Comtal per imitació dels teatres madrilenys. Aquest interès ultrapassava l’escenari de la Casa de Comèdies, amb un curiós comerç dels textos i la possibilitat d’una pràctica privada. D’aquesta manera s’observa com aquest gènere importat pogué arrelar entre el públic barceloní, esp…
Desarrollo de modelos experimentales de LGMDD2 y rastreo de fármacos
2023
La distrofia muscular de cinturas tipo D2 (Limb-girdle muscular dystrophy type D2, LGMDD2) es una enfermedad genética ultra rara para la cual no existe tratamiento. Las principales características clínicas de la LGMDD2 son la debilidad y degeneración muscular progresiva que afecta a las cinturas pélvica y escapular de forma predominante. En 2013 se identificó la LGMDD2 como una miopatía autosómica dominante causada por una mutación en el gen de la transportina 3 (TNPO3), dando como resultado una proteína mutante con una extensión de 15 aminoácidos adicionales: TNPO3mut. TNPO3 es una β-importina responsable de la importación nuclear de proteínas ricas en serina/arginina (proteínas SR), invol…

The 2D:4D ratio and its relationship with other androgenisation parameters in parents of individuals with autism spectrum disorders.
2013
The 2D:4D ratio is the quotient between the index and ring fin-ger lengths and is a non-direct indicator of androgenisation. If prenatal tes-tosterone levels in the amniotic fluid are high then the probability increases of developing lower ratio values. It has been suggested that people with au-tism spectrum disorders (ASD) and their parents may have highly andro-genised brains, and for this reason the 2D:4D ratio is used as a marker of such idiosyncrasies. This study aims to analyse if parents of people with ASD differ from the general population in several parameters of andro-genisation related to the 2D:4D ratio. The sample was composed of 43 parents of offspring with ASD and 42 controls…
Thiazole Analogues of the Marine Alkaloid Nortopsentin as Inhibitors of Bacterial Biofilm Formation
2020
Anti-virulence strategy is currently considered a promising approach to overcome the global threat of the antibiotic resistance. Among different bacterial virulence factors, the biofilm formation is recognized as one of the most relevant. Considering the high and growing percentage of multi-drug resistant infections that are biofilm-mediated, new therapeutic agents capable of counteracting the formation of biofilms are urgently required. In this scenario, a new series of 18 thiazole derivatives was efficiently synthesized and evaluated for its ability to inhibit biofilm formation against the Gram-positive bacterial reference strains Staphylococcus aureus ATCC 25923 and S. aureus ATCC 6538 a…
Open Service Innovation: The Case of Tourism Firms in Scandinavia
2016
Most empirical research investigating open innovation has focused on the development of new physical products in manufacturing industries, whereas open service innovation has not been researched correspondingly. Services have some characteristics that distinguish them from physical products, which may affect the types of open innovation practice utilised during service innovation processes. Tourism services comprise a subset of services that is particularly distant from tangible products. Therefore, the exploration of how tourism firms utilise different types of open innovation practice offers a valuable opportunity to learn about the nature of open service innovation practices. Thus, this …
Autor y lector en la traducción catalana del Decamerón de Boccaccio: análisis de una asimilación
2013
Resumen: Ese trabajo analiza la traduccion catalana del Decameron de 1429 centrandose en las particularidades de la narrativa, especialmente la relacion entre el autor y el lector. Sin dejar de lado aspectos propios de la traduccion en aquel momento, se enfatiza el valor de este texto, en ocasiones considerado una mera adaptacion, como una obra humanistica, un documento de la asimilacion del humanismo italiano en la Corona de Aragon. El texto catalan es una muestra de como se entendieron las ideas narrativas del autor italiano, pues muchos de los que se han considerado defectos en la obra responden a estrategias narrativas en funcion de un determinado publico y una determinada cultura. Se t…
