Enhancing the deployment of vehicle-to-infrastructure (V2I) communications throughcomprehensive temporal approach.
No full textIn the future, mobility will be connected, cooperative, and autonomous where self-driven vehicles will coexist together with human-driven ones, resulting in a safer and more efficient traffic flow leading to a reduction of CO2 emissions, life loss, and time spent on the road. That is why, in achieving the goal of having connected, cooperative, and autonomous mobility Vehicle-to-Everything (V2X) communications play a key role as they enable the communication between vehicles and between vehicles and the surrounding environment (infrastructure, pedestrians, etc.). Therefore, to lay the foundation for this future, there has been a great deal of progress in recent years to enable the exchange of information from the vehicles on the road to the infrastructure through Vehicle to Infrastructure (V2I) communications. For the envisioned future of connected, cooperative, and autonomous mobility to become a reality, V2I deployments are essential. They facilitate seamless mobility across highways and urban environments. However, the landscape of V2I communications is continuously evolving, with new features being introduced regularly. This dynamic nature necessitates ongoing updates and adaptations, precluding the possibility of a definitive, one-time deployment. Moreover, as V2I technology is still in the development phase, new deployments will be imperative to accommodate the advancements in this field. In this thesis, we show that the real deployment of V2I communications is improved when three stages of a V2I deployment (initial deployment, enhancement, and future perspectives) are considered. In the context of this research work the three stages are: • Initial deployment: The establishment of infrastructure is crucial for facilitating V2I communications. This foundational phase significantly enhances the initial deployment of V2I communications during the earliest field installations. Decisions made during this critical stage have a lasting impact on the entire lifespan of the deployment, setting the groundwork for future scalability and effectiveness. Given that the initial installation cost is substantial, relocating the components from their original deployment positions incurs significant expenses. Enhancement: Ongoing supervision of the installed facility is paramount for integrating new features effectively. It is highly advisable to rigorously test these features before their field implementation to ensure minimal errors. This proactive approach guarantees the reliability and efficiency of the system as it evolves. • Future perspectives: Finally, all the acquired knowledge and experience assist when engineering new V2I designs and features
Tracking dynamic evolution of low‐ and intermediate‐risk differentiated thyroid cancer: Identification of individuals at risk of recurrence
No full textObjective: The generally good prognosis of low- and intermediate-risk differentiated thyroid cancer (DTC) underscored the need to identify those few patients who relapse.
Design: Records of 299 low- or intermediate-risk DTC patients (mean follow-up 8.2 ± 6.2 years) were retrospectively reviewed. The sample was classified following the American Thyroid Association (ATA) dynamic risk stratification (DRS) system.
Patients and measurement: After classifying patients according to DRS at the first visit following initial therapy (FU1), structural recurrence occurred in 2/181 (1.1%), 5/81 (6.2%) and 13/26 (50.0%) with excellent, indeterminate and biochemical incomplete response to treatment, respectively. All relapses but one happened within 5 years from FU1. Univariate analysis comparing excellent, indeterminate and biochemical incomplete with structural incomplete responses at the end of the follow-up, identified tumour size (p < .001), T status (<0.001), positive lymph nodes (N) (p < .01), multifocality (p < .004), need of additional radioactive iodine (RAI) (p < .0001) and first DRS status (p < .0003) as risk factors of recurrence. In the multivariate analysis, only RAI remained statistically significant (p < .02). Comparison between excellent and indeterminate with biochemical and structural incomplete responses, identified tumour size (p < .0004), T (p < .01), N (p < .0001), bilaterality (p < .03), first DRS status (p < .0001) and RAI (p < .001) as recurrence risk factors. T (p < .01) and first DRS (p < .0006) were confirmed in the multivariate analysis.
Conclusions: Patients with DTC classified as low- or intermediate-risk of recurrence with excellent response to treatment at FU1 rarely develop structural disease and this occurs almost exclusively in the first 5 years. Initial DRS status is an accurate tool for determining the risk of recurrence
A 3D printed ultra-short dental implant based on lattice structures and ZIRCONIA/Ca2SiO4 combination
No full textAdditive Manufacturing (AM) enables the generation of complex geometries and controlled internal cavities that
are so interesting for the biomedical industry due to the benefits they provide in terms of osseointegration and
bone growth. These technologies enable the manufacturing of the so-called lattice structures that are cells with
different geometries and internal pores joint together for the formation of scaffold-type structures. In this
context, the present paper analyses the feasibility of using diamond-type lattice structures and topology optimisation for the re-design of a dental implant. Concretely, a new ultra-short implant design is proposed in this
work. For the manufacturing of the implant, digital light processing additive manufacturing technique technology is considered. The implant was made out of Nano-zirconia and Nano-Calcium Silicate as an alternative
material to the more common Ti6Al4V. This material combination was selected due to the properties of the
calcium-silicate that enhance bone ingrowth. The influence of different material combination ratios and lattice
pore sizes were analysed by means of FEM simulation. For those simulations, a bio-material bone-nanozirconia
model was considered that represents the final status after the bone is integrated in the implant. Results shows that the mechanical properties of the biocompatible composite employed were suitable for dental implant applications in dentistry. Based on the obtained results it was seen that those designs with 400 μm and 500 μm pore
sizes showed best performance and led to the required factor of safety
Improvement in quality of life in patients with Hailey-Hailey disease treated with ablative CO2 laser
No full textAbstract Introduction and objectives Hailey-Hailey disease (HHD), or benign familial pemphigus, is a rare autosomal dominant genodermatosis characterized by the formation of blisters. Eruptions are usually located in large skin folds, and when blisters become infected the condition can be very painful and disabling. HHD is difficult to treat. Many topical and systemic treatments have been used to bring exacerbations under control, but none have achieved medium- to long-term remission.
Patients and methods Retrospective study of 8 patients with HHD treated with carbon dioxide laser therapy in our hospital between 1999 and 2011. The patients mean age was 50.7 years. The 4 men and 4 women were followed for between 1 and 12 years.
Results Satisfactory outcomes were achieved for 6 of the patients. Clinical improvement was observed in more than 75% of the affected area in 4 patients and in 50% to 75% of the area in 2 patients. The effect of treatments was maintained over time. The poorest outcomes were observed in patients treated at lower potencies. When blistering recurred after treatment, a second laser session achieved a good response. We observed no adverse events other than slight changes in skin texture and pigmentation.
Conclusions Carbon dioxide laser therapy was safe and effective in producing medium- to long-term improvement in HHD symptoms that were refractory to conventional treatments
Application of a cost-effective methodology for the refurbishment of DOCOMOMO buildings. A case study in Northern Spain
No full textThe energy rehabilitation of listed buildings guaranteeing heritage values but allowing a use that contributes to their conservation, supposes a
challenge with the need of a holistic approach. Buildings of the Modern Movement, many of which are registered as DOCOMOMO (DOcumentation
and COnservation of buildings, sites and neighbourhoods of the MOdern Movement), are a particular case since many of them are not yet listed or
are under unclear requirements. This paper explores the inclusion of a cost-effective methodology as part of the decision-making in the energy
rehabilitation of these DOCOMOMO buildings, applying it to the case study of an office building located in the north of Spain. Different scenarios
were studied balancing cost-effectiveness, energy efficiency and rehabilitation requirements. In this case study, the analysis may allow policymakers
to have supportive arguments to subsidize certain elements (as e.g., steel frames), or allow the use of alternative options with similar aesthetic
characteristics, but at a much lower cost. This second option will constitute the unique cost-effective scenario, with energy savings of between 25.36% and 38.8%. The inclusion of a cost-effective methodology as part of the mechanics for decision-making in the energy refurbishment of
DOCOMOMO buildings permits the optimisation of the intervention guaranteeing their use and the conservation of heritage values

Increasing the sustainability of the stabilization-solidification of potentially toxic elements contained in tailings from an active mine using a modified lime mortar
No full textThe use of a modified lime mortar as a binder for the stabilization/solidification of mine tailings presents a promising and sustainable solution for immobilizing potentially toxic elements found in these waste materials compared to cement mortars. The effectiveness of this modified lime mortar in avoiding the mobility of toxic elements, namely lead (Pb) and arsenic (As), in mine tailings has been thus studied. Encapsulating matrices of 1:1 and 2:1 tailings waste/air lime ratios were prepared. Due to the content of potentially pozzolanic compounds in the mine tailings, mainly some silicate phases, 1:1 matrices showed better mechanical strength than 2:1 samples, ascribed to a more intense pozzolanic reaction. SEM observations identified needle-shaped C-S-H structures. The hardened materials showed good endurance against freeze–thaw cycles. The semi-dynamic tank test demonstrated the effective encapsulation of the toxic components due to the use of lime mortars, yielding values of released Pb and As below the detection limit in all instances. Considering the cost-effectiveness, widespread availability, and ease of use, the use of modified lime mortar for the treatment of mine tailings can be recommended to mitigate the environmental impacts of mining activities
Think star, think men? Implicit star performer theories
No full textThe star performer gender gap highlights women's challenges in being recognized as star performers. We investigated whether people hold shared beliefs about characteristics star performers possess (i.e., implicit star performer theories, ISPTs) and whether perceptions of stars are (a) gendered and (b) context-specific. Guided by categorization theory, we argue that individuals have shared perceptions of what constitutes a star performer. Employing an inductive approach, we uncovered the existence of ISPTs that are distinct and differ from previously identified implicit theories, such as those about leadership. Specifically, stars were believed to have six characteristics: Driven, Relational, Extraordinary, Fascinating, Tenacious, and Brilliant. We then applied role congruity theory to argue that perceptions of star performers would be gendered and context-dependent. Using an experimental approach, we ascertained that people associated star performers with more masculine than feminine attributes, what we labeled the think star, think men phenomenon. Moreover, this association was context-dependent, such that the association of star performers with masculine attributes was stronger in men-dominated occupations. Our third study used a non-reactive approach (i.e., “Princeton trilogy”), and results showed that star performers are seen as possessing more masculine attributes than very good employees. Overall, our three studies using inductive, experimental, and indirect methods based on eight samples of 2322 participants consistently supported the existence of ISPTs and the think star, think men phenomenon, improving our understanding of the star performer gender gap
Pop-off mechanisms as renoprotective mediators in children with posterior urethral valves: A systematic review and meta-analysis
No full textBackground: Pop-off mechanisms are potential pressure-relieving mediators in patients diagnosed with posterior urethral valves (PUV). This systematic review aimed to synthesize the existing evidence regarding the protective effect of pop-off mechanisms on renal function in children with PUV.
Methods: We conducted a systematic review of the literature that involved an extensive search in the main databases of the medical bibliography. Three independent reviewers selected the relevant articles. Methodological quality was rated using the Newcastle Ottawa Scale index. We used random meta-analyses to compare different outcomes (serum creatine, Nadir serum creatinine, and Chronic Kidney Disease) between children with PUV and pop-off mechanisms and those with PUV without pop-off mechanisms.
Results: 10 studies with data from 896 participants were included in this review. Seven articles reported serum creatinine values for each group and 3 of them found significant differences between groups. The random-effects meta-analysis for serum creatinine showed significant lower mean (diff = -52.88 μmol/L [95 % CI -73.65 to -32.11]) in the group of children with pop-off mechanisms, and the random-effects meta-analysis for Nadir serum creatinine showed a marginally significantly lower mean in the group of children with pop-off mechanisms (diff = -12.00 μmol/L [95 % CI -24.04 to 0.04]). The random-effect meta-analysis for Chronic Kidney Disease resulted in a significant risk reduction for the group of children with pop-off mechanisms (odds ratio = 0.48 [95 % CI 0.23 to 0.98]).
Conclusions: Children with PUV and pop-off mechanisms show better renal function and lower risk of Chronic Kidney Disease than those with PUV without pop-off mechanisms suggesting these mechanisms may act as renoprotective mediators. The high heterogeneity between studies in the assessment of renal function and long-term outcomes calls for a cautious interpretation of these findings. Future studies that stratify by different types of pop-off mechanisms and use standardized metrics, such as Nadir creatinine, are needed
