Diseño y validación de un instrumento de investigación para proponer metodología de gestión de proyectos
The methodologies for the design and management of projects are increasingly necessary and applied with greater frequency in the public sector in Latin America. There are continually updates and new approaches in the management of investment projects, so the study of methodologies is relevant at the investigative level. The design of reliable research instruments that serve to promote the use of these methodologies is important to ensure quality in the process. Therefore, the objective of this study is to design and validate an instrument that allows the systematic collection and management of project information to obtain the variables that allow defining the appropriate methodology for each organization. In this study, the public sector has taken as a reference the Undersecretary of Fisheries Resources (SRP) in Ecuador. The instrument takes as reference the International Organization for Standardization (ISO) 10006 Standard, the Project Management Fundamentals Guide, by its name in English Project Management Body of Knowledge (PMBOK), the Project Design Methodologies of the Polytechnic University of Catalonia (MDP-UPC) and the National Secretariat for Planning and Development (SENPLADES) of Ecuador. As a result, a survey was developed, whose instrument was internally and externally validated based on reliability, content, and construct parameters. Factorial analysis was performed to determine variables using the SPSS statistical system. Finally, the designed instrument has been validated, ensuring that it is reliable and meets the necessary parameters to obtain variables that define the methodology for project development in the public sector of Ecuador.Las metodologías para el diseño y gestión de proyectos son cada vez más necesarias y aplicadas con mayor frecuencia en el sector público en Latinoamérica.

Performance analysis of multi-source wireless multimedia content delivery
In order to create an improved experience in variable network delivery conditions, immersive multimedia content can be delivered over existing network environments, from multiple sources. These sources are normally servers located in the cloud, in various locations. Storytelling and certain related content, such as the immersive opera multimedia data in the context of the European Horizon2020 project TRACTION, require multimedia players to be able to receive content simultaneously from several locations, and at times, merge the content, creating new content in real-time. For instance, 360° recordings and polygonal 3D content can be delivered from different locations,and the end-user receives the unified content on his or her device. This paper introduces a study of how devices can be analysed, in terms of metrics, when receiving multimedia content from multiple sources, as the network and the devices have constraints regarding performance and video quality
FPGA-Based Fused Smart Sensor for Dynamic and Vibration Parameter Extraction in Industrial Robot Links
Intelligent robotics demands the integration of smart sensors that allow the controller to efficiently measure physical quantities. Industrial manipulator robots require a constant monitoring of several parameters such as motion dynamics, inclination, and vibration. This work presents a novel smart sensor to estimate motion dynamics, inclination, and vibration parameters on industrial manipulator robot links based on two primary sensors: an encoder and a triaxial accelerometer. The proposed smart sensor implements a new methodology based on an oversampling technique, averaging decimation filters, FIR filters, finite differences and linear interpolation to estimate the interest parameters, which are computed online utilizing digital hardware signal processing based on field programmable gate arrays (FPGA)
A novel production workflow and toolset for opera co-creation towards enhanced societal inclusion of people
Opera uses all the visual and performing arts to create extraordinary worlds of passion and sensibility. It is rightly recognised as a great achievement of European culture. And yet a form that once inspired social and artistic revolutions is often seen as the staid preserve of the elite. With rising inequality and social exclusion, many see opera—if they think of it at all—as symbolic of what is wrong in Europe today. This paper presents the technological and scientific approach of the European H2020 TRACTION project that aims to use opera as a path for social and cultural inclusion, making it once again a force for radical transformation. TRACTION wants to define new forms of artistic creation through which the most marginalised groups (e.g. migrants, the rural poor, young offenders and others) can work with artists to tell the stories that matter now. By combining best practices in participatory art with media technology’s innovations of language, form and process, the project is defining new approaches to co-creation and innovation, exploring novel audiovisual formats based in European cultural heritage, such as opera

Effective description of general extensions of the Standard Model: the complete tree-level dictionary
We thank Nuria Rius and Arcadi Santamaria for an interesting discussion that motivated
this work. We also thank Paco del Águila and Toni Pich for useful comments.We compute all the tree-level contributions to the Wilson coefficients of
the dimension-six Standard-Model effective theory in ultraviolet completions with general
scalar, spinor and vector feld content and arbitrary interactions. No assumption about
the renormalizability of the high-energy theory is made. This provides a complete ultraviolet/
infrared dictionary at the classical level, which can be used to study the low-energy
implications of any model of interest, and also to look for explicit completions consistent
with low-energy dataThe work

Long-term Mortality in HIV-Positive Individuals Virally Suppressed for >3 Years With Incomplete CD4 Recovery
Virally suppressed HIV-positive individuals on combination antiretroviral therapy who do not achieve a CD4 count >200 cells/µL have substantially increased long-term mortality. The increased mortality was seen across different patient groups and for all causes of deat
Comparison of dynamic monitoring strategies based on CD4 cell counts in virally suppressed, HIV-positive individuals on combination antiretroviral therapy in high-income countries: a prospective, observational study
BACKGROUND Clinical guidelines vary with respect to the optimal monitoring frequency of HIV-positive individuals. We compared dynamic monitoring strategies based on time-varying CD4 cell counts in virologically suppressed HIV-positive individuals. METHODS In this observational study, we used data from prospective studies of HIV-positive individuals in Europe (France, Greece, the Netherlands, Spain, Switzerland, and the UK) and North and South America (Brazil, Canada, and the USA) in The HIV-CAUSAL Collaboration and The Centers for AIDS Research Network of Integrated Clinical Systems. We compared three monitoring strategies that differ in the threshold used to measure CD4 cell count and HIV RNA viral load every 3-6 months (when below the threshold) or every 9-12 months (when above the threshold). The strategies were defined by the threshold CD4 counts of 200 cells per μL, 350 cells per μL, and 500 cells per μL. Using inverse probability weighting to adjust for baseline and time-varying confounders, we estimated hazard ratios (HRs) of death and of AIDS-defining illness or death, risk ratios of virological failure, and mean differences in CD4 cell count. FINDINGS 47 635 individuals initiated an antiretroviral therapy regimen between Jan 1, 2000, and Jan 9, 2015, and met the eligibility criteria for inclusion in our study. During follow-up, CD4 cell count was measured on average every 4·0 months and viral load every 3·8 months. 464 individuals died (107 in threshold 200 strategy, 157 in threshold 350, and 200 in threshold 500) and 1091 had AIDS-defining illnesses or died (267 in threshold 200 strategy, 365 in threshold 350, and 459 in threshold 500). Compared with threshold 500, the mortality HR was 1·05 (95% CI 0·86-1·29) for threshold 200 and 1·02 (0·91·1·14) for threshold 350. Corresponding estimates for death or AIDS-defining illness were 1·08 (0·95-1·22) for threshold 200 and 1·03 (0·96-1·12) for threshold 350. Compared with threshold 500, the 24 month risk ratios of virological failure (viral load more than 200 copies per mL) were 2·01 (1·17-3·43) for threshold 200 and 1·24 (0·89-1·73) for threshold 350, and 24 month mean CD4 cell count differences were 0·4 (-25·5 to 26·3) cells per μL for threshold 200 and -3·5 (-16·0 to 8·9) cells per μL for threshold 350. INTERPRETATION Decreasing monitoring to annually when CD4 count is higher than 200 cells per μL compared with higher than 500 cells per μL does not worsen the short-term clinical and immunological outcomes of virally suppressed HIV-positive individuals. However, more frequent virological monitoring might be necessary to reduce the risk of virological failure. Further follow-up studies are needed to establish the long-term safety of these strategies.
