Abstract

Abstract Accurate short-term predictions of COVID-19 cases with empirical models allow Health Officials to prepare for hospital contingencies in a two–three week window given the delay between case reporting and the admission of patients in a hospital. We investigate the ability of Gompertz-type empiric models to provide accurate prediction up to two and three weeks to give a large window of preparation in case of a surge in virus transmission. We investigate the stability of the prediction and its accuracy using bi-weekly predictions during the last trimester of 2020 and 2021. Using data from 2020, we show that understanding and correcting for the daily reporting structure of cases in the different countries is key to accomplish accurate predictions. Furthermore, we found that filtering out predictions that are highly unstable to changes in the parameters of the model, which are roughly 20%, reduces strongly the number of predictions that are way-off. The method is then tested for robustness with data from 2021. We found that, for this data, only 1–2% of the one-week predictions were off by more than 50%. This increased to 3% for two-week predictions, and only for three-week predictions it reached 10%.

Abstract

IntroductionThis study aims to investigate the relationship between deprivation, as measured by a socioeconomic deprivation index (SDI) score for census tract urban areas, and COVID-19 infections and vaccine uptake among children and adolescents before and after the vaccination rollout in Catalonia, Spain.MethodsWe conducted a population-based cohort study using primary care records. Individuals were followed 3 months before the start of the vaccination campaign in Spain and 3 months after. Children (5–11 years) and adolescents (12–15 years) with at least 1 year of prior history observation available and without missing deprivation data. For each outcome, we estimated cumulative incidence and crude Cox proportional-hazard models by SDI quintiles, and hazard ratios (HRs) of COVID-19 infection and vaccine uptake relative to the least deprived quintile, Q1.ResultsBefore COVID-19 vaccination rollout, 290,625 children and 179,685 adolescents were analyzed. Increased HR of deprivation was associated with a higher risk of COVID-19 infection in both children [Q5: 1.55 (95% CI, 1.47–1.63)] and adolescents [Q5: 1.36 (95% CI, 1.29–1.43)]. After the rollout, this pattern changed among children, with lower risk of infection in more deprived areas [Q5: 0.62 (95% CI, 0.61–0.64)]. Vaccine uptake was higher among adolescents than children, but in both age groups, non-vaccination was more common among those living in more deprived areas (39.3% and 74.6% in Q1 vs. 26.5% and 66.9% in Q5 among children and adolescents, respectively).ConclusionsChildren and adolescents living in deprived areas were at higher risk of COVID-19 non-vaccination. Socioeconomic disparities in COVID-19 infection were also evident before vaccine rollout, with a higher infection risk in deprived areas across age groups. Our findings suggest that changes in the association between deprivation and infections among children after the vaccine rollout were likely due to testing disparities.

Abstract

Abstract The extracellular matrix and the correct establishment of epithelial cell polarity plays a critical role in epithelial cell homeostasis and cell polarity. In addition, loss of tissue structure is a hallmark of carcinogenesis. In this study, we have addressed the role of extracellular matrix in the cellular responses to TGF-β. It is well known that TGF-β is a double-edged sword: it acts as a tumor suppressor in normal epithelial cells, but conversely has tumor-promoting effects in tumoral cells. However, the factors that determine cellular outcome in response to TGF-β remain controversial. Here, we have demonstrated that the lack of extracellular matrix and consequent loss of cell polarity inhibits TGF-β-induced apoptosis, observed when endometrial epithelial cells are polarized in presence of extracellular matrix. Rather, in absence of extracellular matrix, TGF-β-treated endometrial epithelial cells display features of epithelial-to-mesenchymal transition. We have also investigated the molecular mechanism of such a switch in cellular response. On the one hand, we found that the lack of Matrigel results in increased AKT signaling which is sufficient to inhibit TGF-β-induced apoptosis. On the other hand, we demonstrate that TGF-β-induced epithelial-to-mesenchymal transition requires ERK and SMAD2/3 activation. In summary, we demonstrate that loss of cell polarity changes the pro-apoptotic function of TGF-β to tumor-associated phenotype such as epithelial-to-mesenchymal transition. These results may be important for understanding the dual role of TGF-β in normal versus tumoral cells.

Abstract

During the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mitigation policies for children have been a topic of considerable uncertainty and debate. Although some children have co-morbidities which increase their risk for severe coronavirus disease (COVID-19), and complications such as multisystem inflammatory syndrome and long COVID, most children only get mild COVID-19. On the other hand, consistent evidence shows that mass mitigation measures had enormous adverse impacts on children. A central question can thus be posed: What amount of mitigation should children bear, in response to a disease that is disproportionally affecting older people? In this review, we analyze the distinct child versus adult epidemiology, policies, mitigation trade-offs and outcomes in children in Western Europe. The highly heterogenous European policies applied to children compared to adults did not lead to significant measurable differences in outcomes. Remarkably, the relative epidemiological importance of transmission from school-age children to other age groups remains uncertain, with current evidence suggesting that schools often follow, rather than lead, community transmission. Important learning points for future pandemics are summarized.

Abstract

Acute respiratory viral infections pose a significant healthcare burden on the pediatric population globally, but data on the dissemination pattern in the community due to the coronavirus disease 2019 (COVID-19) pandemic are scarce. We conducted a 2-year prospective multicenter study in Catalonia (Spain) that examined the prevalence and coinfection dynamics of respiratory viruses among 1276 pediatric patients from different age groups attending primary care. Coinfection analysis demonstrated complex patterns and revealed a coinfection rate of 23.8% for severe acute respiratory syndrome coronavirus 2, often in association with rhinovirus or influenza A. This study provides valuable data to understand postpandemic viral interactions, which is imperative for public health interventions. [ABSTRACT FROM AUTHOR]

Abstract

PurposeTo analyse the association between the mortality during the summer 2022 and either high temperatures or the COVID-19 wave with data from the Catalan Health Care System (7.8 million people).MethodsWe performed a retrospective study using publicly available data of meteorological variables, influenza-like illness (ILI) cases (including COVID-19) and deaths. The study comprises the summer months of the years 2021 and 2022. To compare the curves of mortality, ILI and temperature we calculated the z-score of each series. We assessed the observed lag between curves using the cross-correlation function. Finally, we calculated the correlation between the z-scores using the Pearson correlation coefficient (R2).ResultsDuring the study period, 33,967 deaths were reported in Catalonia (16,416 in the summer of 2021 and 17,551 in the summer of 2022). In 2022, the observed lag and the correlation between the z-scores of temperature and all-cause deaths was 3 days and R2 = 0.86, while between ILI and all-cause deaths was 22 days and R2 = 0.21. This high correlation between temperature and deaths increased up to 0.91 when we excluded those deaths reported as COVID-19 deaths, while the correlation between ILI and non-COVID-19 deaths decreased to −0.19. No correlation was observed between non-COVID deaths and temperature or ILI cases in 2021.ConclusionOur study suggests that the main cause of the increase in deaths during summer 2022 in Catalonia was the high temperatures and its duration. The contribution of the COVID-19 seems to be limited.

Abstract

Measuring soil quality and the use of indicators for its evaluation is a worldwide challenge. In Garrotxa Volcanic Zone Natural Park (northeastern Spain), different parameters related to oribatid mites as indicators of soil quality were evaluated under different land uses: forest, pasture, and a biennial double-crop rotation of forage crops. In forage crops, previous fertilization management (one based on mineral fertilizers, three on cattle manure, and one using both types) was also evaluated. Three samplings (April, June, and September) were performed over one season. Fifty-four oribatid species belonging to 28 families were identified. Abundance was the lowest in June for all land uses (average of 1184 individuals m−2). In the study period, abundance, diversity (Shannon index, H'), and dominance (Berger–Parker index, d) varied with different land uses, with the highest values of abundance and H' in forests (9287 individuals m−2 and 2.19, respectively) and the lowest dominance in forests (d = 0.29) without differences between the other uses. Additionally, in the studied parameters, no differences were associated with previous fertilization management in forage crops. Hypochthoniella minutissima, Xenillus (X.) tegeocranus characterized the forest system, Epilohmannia cylindrica minima the forage crops, and Tectocepheus sarekensis the pasture. In pasture, the dominance of the parthenogenetic species Tectocepheus sarekensis raises concerns about potential management constraints. [ABSTRACT FROM AUTHOR]

Abstract

The European Commission (hereafter EC) and international countries are closely involved in the activities of the OECD (Organization for Economic Co-operation and Development). Together, they focus their efforts on fostering economic development, through providing R&D Tax Incentives to let companies optimise their Corporation Tax and have therefore more resources to keep investing in R&D and technological innovation. The project entails the establishment of a new enterprise, Novatech Consulting Group, S.R.L., dedicated to providing consultancy services for R&D Tax Credits across different EU and international target countries. The aim of Novatech consists of delivering unparalleled expertise in R&D Tax Credit consulting services, acknowledging their complexity and variability, and reaching the position as a trusted partner for enterprises seeking to claim the incentive to optimise the Corporation Tax. Thus, the present thesis aims to study the creation of a specialised consultancy uniquely focused on optimising tax benefits for businesses engaged in R&D and technological innovation activities. The methodology involves a comprehensive analysis of tax regulations, country-specific incentives, factors influencing R&D tax credits, and the various markets. The project also includes the branding, target audience and segmentation, decision-making matrixes to select target countries, corporation tax analysis, strategic analysis, marketing mix, and financial and legal plans. The consecution of the present project provides a complete understanding of legal considerations, global variations, and strategic approaches relevant to the establishment of a consultancy of this nature. The positive outcome of this project is the enhanced ability to strategically study the position of Novatech in various international markets, considering different factors and approaches. The present thesis offers therefore a clear understanding of how to establish a new consulting company with a digita

Abstract

This thesis delves into the intricate dynamics of culture and other determinants on consumer attitudes towards sustainable consumption, a pivotal element in realizing the United Nations' 2030 Agenda for Sustainable Development, specifically addressing Goal 12, which focuses on sustainable consumption and production patterns. By employing a systematic review methodology, the study critically analyzed 95 quantitative research articles published between 2019 and 2023. The aim was to dissect and understand the myriad of factors influencing sustainable consumption behavior (SCB) across various cultural landscapes globally. The findings illuminate the profound impact of cultural variations on SCB. Particularly in cross-continental studies, it was evident that cultural dimensions such as collectivism, longterm orientation, and locus of control exhibited divergent influences in different countries, notably between Eastern and Western societies. However, certain factors, grounded in the Theory of Planned Behavior, showed a universal impact on sustainable consumption across diverse cultures. By systematically synthesizing this information, the thesis identified 36 sustainable consumption factors and further organized them into 12 categories from a stakeholder perspective. This comprehensive categorization significantly enhances the practical understanding and application of sustainable consumption strategies in various sectors and cultural settings. For future work, the thesis recommends expanding the scope of academic databases to include a broader and more current range of sources. Additionally, conducting multinational quantitative research, particularly focusing on the role of cultural differences in power distance and locus of control, is advised to provide clearer insights into the cultural context's impact on SCB. This will not only broaden the application of Hofstede’s cultural dimensions but also enhance the development of more effective SCB policies and practices ac

Abstract

This thesis endeavors to present a comprehensive overview of the global state of solid propellant technology. Its genesis lies in the imperative to furnish contextual backing for a patent conceived, titled " Photo-polymerization for additive manufacturing of composite solid propellants", aimed at subsequent coherent market analysis. Solid propellants represent pivotal constituents utilized as propulsion fuel in rockets, missiles, and analogous systems. Comprised of solid chemical compounds—such as polymers, aluminum compounds, or graphite dioxide—combined with oxidizers and adjunctive additives, these materials furnish a steadfast energy source and exhibit prolonged stability, rendering them versatile for multifarious applications encompassing rocketry, launcher mechanisms, fire extinguishing agents, and airbag expansion. This work assumes the form of a Patent Landscape Report (PLR), wherein meticulous data processing and manipulation from a discerningly curated Patent Database will distill pertinent information and delineate trends germane to solid propellant technology. Patents are recognized as potent repositories of information, and PLRs are purposefully devised to distill intrinsic insights from these documents, thereby evaluating the extant technological progress within a sector and furnishing strategic support to companies and institutions within the field. Additionally, this endeavor aspires to provide an encompassing contextual understanding of solid propellants by delineating the distinct stages within the production process. Moreover, it endeavors to proffer an exhaustive introduction to the realm of patents, facilitating a robust foundational understanding pivotal for a more nuanced comprehension of the ensuing analytical processes. The exploration and analysis of the collected data will be executed utilizing R, an opensource programming language widely acclaimed for its prowess in data manipulation and visualization. Such an approach ensures comprehensi

Abstract

In the modern business environment with rapid technological changes, the adoption of agile methodologies within large organizations has increased dramatically. This thesis aims to shed light on the scaling of agile methods, focusing on two widely adopted scaling frameworks: SAFe (Scaled Agile Framework) and LeSS (Large Scale Scrum). The primary objective is to gain insights into the methods, challenges, and success factors associated with large-scale agile transformations from 2017 to 2023. The research conducts a systematic literature review which analyzes 15 case studies published between 2017 and 2023. The study provides key findings relating to agile methods, challenges, and success factors, providing a comprehensive understanding of the current landscape of large-scale agile transformations. The research revealed four agile methods are frequently adopted: Scrum, Lean, Kanban, and Extreme Programming (XP). Scrum showed up to be the most used method, followed by Lean and Kanban. Combining agile methods is also common, such as integrating Scrum, XP, and Lean or adopting hybrid methods like Scrumban. Nine themes of challenges were uncovered, with communication and coordination, culture and mindset, and management and strategy as the main challenges. All challenges were further organized into subthemes, offering detailed insights into issues such as information gaps, lack of vision, and coordination struggles among teams. The thesis also identified ten themes of success factors, addressing most of the challenge themes. Communication and coordination, management and strategy, and requirements engineering stood out as primary contributors to successful large-scale agile transformations. Subthemes within each success factor category provide a detailed understanding of the individual factors driving success

Abstract

The respiratory syncytial virus (RSV) causes 70% of bronchiolitis cases and thousands of annual deaths, particularly in the paediatric population under six months, placing a significant burden on the public health system. In October 2023, the monoclonal antibody nirsevimab was implemented for the first time in Catalonia in infants to combat the most severe clinical episodes caused by this virus. The primary objective of this study is to evaluate the impact of the first immunisation campaign with nirsevimab on the epidemiology and clinical outcomes of RSV. To this end, pre-pandemic patterns by age group have been characterized and compared with the current season, in addition to analysing the clinical outcomes of a prospective cohort of infants, observing differences between those who received nirsevimab and those who did not. The methodology followed in this study is divided into two major analyses: an epidemiological study and a patient-level study. The epidemiological analysis involves exploring the dynamics of bronchiolitis as an indirect measure of RSV and of the virus itself, conducting comparative analyses using an average pre-pandemic season and differentiating between various age groups. The patient-level analysis consists of a prospective study of clinical variables comparing a cohort that received nirsevimab with another cohort that did not. The results indicate that the pre-pandemic incidence of bronchiolitis followed a very robust pattern each season, which was significantly affected by the pandemic. It has been observed that the introduction of nirsevimab has reduced the incidence of RSV in infants under one year. Additionally, the prospective study determined that infants receiving nirsevimab are less likely to test positive for RSV and develop lower respiratory tract infections compared to those who were not immunised. In conclusion, this study demonstrates that the administration of nirsevimab in Catalonia has reduced the incidence of RSV and lower r, El virus respiratori sincicial (VRS) causa el 70% de les bronquiolitis i milers de morts anuals, particularment en la població pediàtrica menor de sis mesos, generant una càrrega significativa en el sistema públic sanitari. L'octubre de 2023 es va implementar per primera vegada a Catalunya l'anticòs monoclonal nirsevimab en lactants, per combatre els episodis clínics més greus causats per aquest virus. L'objectiu principal d'aquest estudi és avaluar l'impacte de la primera campanya d'immunització amb nirsevimab en l'epidemiologia i els resultats clínics del VRS. Per a això, s'han caracteritzat els patrons prepandèmics per franja d'edat i s'han comparat amb la temporada actual, a més d'analitzar els resultats clínics d'una cohort prospectiva de lactants, observant les diferències entre aquells que han rebut nirsevimab i els que no. La metodologia seguida en aquest estudi es divideix en dues grans anàlisis: un estudi epidemiològic i un estudi a escala pacient. L'anàlisi epidemiològica consisteix a explorar les dinàmiques de bronquiolitis com a mesura indirecta del VRS, i del mateix virus, fent anàlisis comparatives emprant una temporada mitjana prepandèmica i diferenciant entre diferents grups d'edat. L'anàlisi a escala pacient consisteix en un estudi prospectiu de variables clíniques que compara una cohort a la qual se li ha administrat nirsevimab amb una altra cohort a la qual no. Els resultats obtinguts indiquen que la incidència de bronquiolitis prepandèmica seguia un patró molt robust cada temporada, el qual es va veure afectat significativament per la pandèmia. S'ha observat que la introducció del nirsevimab ha reduït la incidència de VRS en els lactants menors d'un any. A més, l'estudi prospectiu ha determinat que els lactants que reben nirsevimab tenen menys probabilitat de donar positiu en VRS i de desenvolupar infeccions respiratòries de les vies baixes en comparació amb aquells que no han estat immunitzats. En conclusió, aquest estudi demostra que l'adminis, El virus respiratorio sincitial (VRS) causa el 70% de las bronquiolitis y miles de muertes anuales, particularmente en la población pediátrica menor de seis meses, generando una carga significativa en el sistema público sanitario. En octubre de 2023, se implementó por primera vez en Cataluña el anticuerpo monoclonal nirsevimab en lactantes, para combatir los episodios clínicos más severos causados por este virus. El objetivo principal de este estudio es evaluar el impacto de la primera campaña de inmunización con nirsevimab en la epidemiología y los resultados clínicos del VRS. Para ello, se han caracterizado los patrones prepandémicos por franja de edad y se han comparado con la temporada actual, además de analizar los resultados clínicos de una cohorte prospectiva de lactantes, observando las diferencias entre aquellos que han recibido nirsevimab y los que no. La metodología seguida en este estudio se divide en dos grandes análisis: un estudio epidemiológico y un estudio a nivel de paciente. El análisis epidemiológico consiste en explorar las dinámicas de bronquiolitis como medida indirecta del RSV, y del propio virus, realizando análisis comparativos empleando una temporada promedio prepandémica y diferenciando entre distintos grupos de edad. El análisis a nivel de paciente consiste en un estudio prospectivo de variables clínicas que compara una cohorte a la que se la ha administrado nirsevimab con otra cohorte a la que no. Los resultados obtenidos indican que la incidencia de bronquiolitis prepandémica seguía un patrón muy robusto cada temporada, el cual se vio afectado significativamente por la pandemia. Se ha observado que la introducción del nirsevimab ha reducido la incidencia de VRS en los lactantes menores de 1 año. Además, el estudio prospectivo ha determinado que los lactantes que reciben nirsevimab tienen menos probabilidad de dar positivo en VSR y de desarrollar infecciones respiratorias de las vías bajas en comparación a aquellos que no han sido inmun, Objectius de Desenvolupament Sostenible::3 - Salut i Benestar

Abstract

In the current global context, the aviation sector stands out as one of the most economically influential industries worldwide, offering a multitude of opportunities. Since its inception, aviation has experienced continuous growth until the onset of the Covid-19 pandemic. However, this growth has come with disadvantages, particularly regarding its environmental impact. This project mainly focuses on exploring a possible solution to mitigate the sector's impact on the environment and the transition to aviation with lower emissions. The central focus of this study lies in the evaluation and quantification of possible measures to reduce emissions in the Spanish aeronautical industry. This study examines the sector's needs by taking the historical evolution of national energy into consideration. It then suggests a series of measures to achieve the objectives proposed at the European level, which have already been set as a national goal. The evaluated measures are divided into four blocks. The first and most impactful is the transition from the current fuel to SAF. The second block considers the offsetting of emissions through various methods such as carbon capture. Lastly, as the final blocks, it considers the emergence of new technologies that are planned to be implemented in the next decade and the possibilities for optimizing existing structures and operations. In order to predict future emissions and compare them with current levels, a comprehensive analysis and calculation of total emissions was conducted to estimate the future emissions. The estimation of future emissions was calculated by combining two factors: the implementation of certain measures and the life cycle analysis of the proposed new fuels, such as SAF. In conclusion, the study analyzes the potential impact of implementing said measures and provides an estimate for the future scenario resulting from their application., Outgoing, Objectius de Desenvolupament Sostenible::7 - Energia Assequible i No Contaminant, Objectius de Desenvolupament Sostenible::13 - Acció per al Clima

Abstract

The flu is an infectious and contagious disease that affects the respiratory system, caused by influenza viruses. In our environment, the flu behaves like a seasonal epidemic. In the northern hemisphere there is an annual flu season between the autumn and winter months. We want to know what their behavior is in other countries, and observe what the conditions are for their start in each country. The aim of this work is to understand the dynamics of the flu in the different countries that make up the European Union together with Norway, the United Kingdom and Switzerland, to see if there is a relationship between the flu epidemic and the climatology of the country, to later be able to use more accurate mathematical models. Likewise, the interaction of climate elements (such as temperature) and climate factors (such as latitude) with the transmission and seasonality of the disease caused by the influenza virus is studied, since its effects on biological systems, in this case specifically in people, are known. Finally, from the results obtained, we can say that the incidence of the flu epidemic and the temperature of each country conform to a decreasing exponential function. Although it would be necessary to be able to analyze it in other geographical regions. But, there is no evidence of a relationship between the onset of influenza epidemics and temperature, and neither for the case of latitude., La grip és una malaltia infecciosa i contagiosa, que afecta l'aparell respiratori, causada pels virus de la influença. En el nostre entorn la grip es comporta com una epidèmia estacional. A l'hemisferi nord anualment hi ha temporada de grip entre els mesos de tardor i hivern. Volem conèixer quin és el seu comportament en altres països, i observar quines són les condicions pel seu inici en cada país. L'objectiu d'aquest treball és entendre les dinàmiques de la grip en els diferents països que formen la Unió Europea juntament amb Noruega, Regne Unit i Suïssa, per veure si hi ha relació entre l'epidèmia de grip i la climatologia del país, per després poder utilitzar models matemàtics més acurats. Així mateix, s'estudia la interacció d'elements del clima (com la temperatura) i factors del clima (com la latitud) amb la transmissió i l'estacionalitat de la malaltia causada pel virus de la grip, ja que els seus efectes sobre els sistemes biològics, en aquest cas concretament en les persones, són coneguts. Finalment, dels resultats obtinguts, podem dir que la incidència de l'epidèmia de grip i la temperatura de cada país, s'ajusten a una funció exponencial decreixent. Tot i que caldria poder-ho analitzar en altres regions geogràfiques. Però, no hi ha una evidència de relació entre l'inici de les epidèmies de grip i la temperatura, i tampoc per al cas de la latitud., La gripe es una enfermedad infecciosa y contagiosa, que afecta el aparato respiratorio, causada por los virus de la influenza. En nuestro entorno la gripe se comporta como una epidemia estacional. En el hemisferio norte anualmente hay temporada de gripe entre los meses de otoño e invierno. Queremos conocer cuál es su comportamiento en otros países, y observar cuáles son las condiciones para su inicio en cada país. El objetivo de este trabajo es entender las dinámicas de la gripe en los diferentes países que forman la Unión Europea junto con Noruega, Reino Unido y Suiza, para ver si hay relación entre la epidemia de gripe y la climatología del país, para después poder utilizar modelos matemáticos más precisos. Así mismo, se estudia la interacción de elementos del clima (como la temperatura) y factores del clima (como la latitud) con la transmisión y la estacionalidad de la enfermedad causada por el virus de la gripe, puesto que sus efectos sobre los sistemas biológicos, en este caso concretamente en las personas, son conocidos. Finalmente, de los resultados obtenidos, podemos decir que la incidencia de la epidemia de gripe y la temperatura de cada país, se ajustan a una función exponencial decreciente. A pesar de que habría que poderlo analizar en otras regiones geográficas. Pero, no hay una evidencia de relación entre el inicio de las epidemias de gripe y la temperatura, y tampoco para el caso de la latitud.

Abstract

En el actual contexto de creciente conciencia ambiental y transición global hacia fuentes de energía más sostenibles, el sector energético se ve impactado por la conocida transición energética. Este estudio explora las implicaciones financieras de dicha transición, centrándose en predecir los precios de las acciones de empresas que operan tanto en el sector de energía renovable como en el convencional. Investigaciones previas han arrojado resultados inconsistentes, motivando una comprensión más profunda de la correlación entre la transición energética y los mercados financieros. Desde esta perspectiva, el estudio busca realizar dos contribuciones principales. En primer lugar, investigar la conexión entre el sentimiento de los inversores hacia la transición energética y su impacto en la predicción de los precios de acciones de las empresas cotizantes. En segundo lugar, evaluar si la herramienta líder de la investigación, la Inteligencia Artificial, puede mejorar significativamente las predicciones en comparación con métodos tradicionales. Para abordar estas preguntas, se probaron tres algoritmos principales: un algoritmo de análisis de series temporales tradicional (modelo Auto Regresivo Integrado de Media Móvil), un algoritmo de aprendizaje automático (modelo de memoria a corto plazo) y un algoritmo de aprendizaje automático que incorpora el índice de sentimiento de los inversores (modelo Long Short Term Memory junto con un índice extraído de noticias relacionadas con la transición energética disponibles en la web, incluyendo cabeceras de revistas, tweets, investigaciones publicadas, entre otros). Los resultados respaldan ambas afirmaciones anteriores según los análisis realizados. Casi la totalidad de las empresas investigadas muestran mejores resultados al utilizar el modelo de IA, y la introducción del índice de sentimiento de los inversores mejora aún más dichos resultados. La investigación contribuye significativamente al resaltar la relación entre el sentimien, In the current context of increasing environmental awareness and the global transition towards more sustainable energy sources, the energy sector is impacting by the well-known energy transition. This study explores the financial implications of this transition, focusing on predicting energy stock prices, for companies operating in both the renewable energy and conventional energy sectors. Previous research has yielded inconsistent results, motivating a deeper understanding of the correlation between the energy transition and financial markets. From this perspective, the mains contribution that this study aims to make are two. First investigating the connection among investors sentiment towards the energy transition and its impact on the prediction of stock prices for the previous subset of listed companies. Secondly, the tool which leads the whole research is the Artificial Intelligence and particularly if its utilisation can significantly improve the predictions compared to traditional methods. In order to answer to these questions, three main algorithms were tested: traditional timeseries analysis algorithm (Auto Regressive Integrated Moving Average model); machine learning algorithm (Long Short Term Memory model); machine learning algorithm with the addition of the investors sentiment index (Long Short Term Memory model plus the index extracted by all the news related to the energy transition at free disposal on the web, which included journal header, tweets, published research and more). As the results shown, both the previous statements are supported by analytical results. Almost the totality of companies investigated show better performances when AI model were used and the introduction of the investors sentiment index improves them. The research makes significant contributions by highlighting the relationship between investor sentiment, energy transition, and energy stock prices.

Abstract

In the current COVID-19 landscape dominated by Omicron subvariants, understanding the timing and efficacy of vaccination against emergent lineages is crucial for planning future vaccination campaigns, yet detailed studies stratified by subvariant, vaccination timing, and age groups are scarce. This retrospective study analyzed COVID-19 cases from December 2021 to January 2023 in Catalonia, Spain, focusing on vulnerable populations affected by variants BA.1, BA.2, BA.5, and BQ.1 and including two national booster campaigns. Our database includes detailed information such as dates of diagnosis, hospitalization and death, last vaccination, and cause of death, among others. We evaluated the impact of vaccination on disease severity by age, variant, and vaccination status, finding that recent vaccination significantly mitigated severity across all Omicron subvariants, although efficacy waned six months post-vaccination, except for BQ.1, which showed more stable levels. Unvaccinated individuals had higher hospitalization and mortality rates. Our results highlight the importance of periodic vaccination to reduce severe outcomes, which are influenced by variant and vaccination timing. Although the seasonality of COVID-19 is uncertain, our analysis suggests the potential benefit of annual vaccination in populations >60 years old, probably in early fall, if COVID-19 eventually exhibits a major peak similar to other respiratory viruses., This research was supported by the Ayudas Fundación BBVA a proyectos investigación científica 2021 under the project BBVA: Epidemiological modelling of SARS-CoV-2 in a post-pandemic surveil- lance context: an open platform for mid-term scenarios and short-term predictions; the Agència de Gestió d’Ajuts Universitaris i de Recerca, Catalonia [grant number 2021 SGR 00582]; and PID-2022- 139216NB-I00 funded by Ministerio de Ciencia e Innovación (MCIN/ AEI/10.13039/501100011033) and by ‘ERDF: A way of making Europe’, by the European Union., Postprint (published version)

Abstract

Background: Countries across Europe have faced similar evolutions of SARS-CoV-2 variants of concern, including the Alpha, Delta, and Omicron variants.Materials and methods: We used data from GISAID and applied a robust, automated mathematical substitution model to study the dynamics of COVID-19 variants in Europe over a period of more than 2 years, from late 2020 to early 2023. This model identifies variant substitution patterns and distinguishes between residual and dominant behavior. We used weekly sequencing data from 19 European countries to estimate the increase in transmissibility ()Db between consecutive SARS-CoV-2 variants. In addition, we focused on large countries with separate regional outbreaks and complex scenarios of multiple competing variants.Results: Our model accurately reproduced the observed substitution patterns between the Alpha, Delta, and Omicron major variants. We estimated the daily variant prevalence and calculated Db between variants, revealing that: (i) Db increased progressively from the Alpha to the Omicron variant; (ii) Db showed a high degree of variability within Omicron variants; (iii) a higher Db was associated with a later emergence of the variant within a country; (iv) a higher degree of immunization of the population against previous variants was associated with a higher Db for the Delta variant; (v) larger countries exhibited smaller Db, suggesting regionally diverse outbreaks within the same country; and finally (vi) the model reliably captures the dynamics of competing variants, even in complex scenarios.Conclusion: The use of mathematical models allows for precise and reliable estimation of daily cases of each variant.

Abstract

Accurate short-term predictions of COVID-19 cases with empirical models allow Health Officials to prepare for hospital contingencies in a two–three week window given the delay between case reporting and the admission of patients in a hospital. We investigate the ability of Gompertz-type empiric models to provide accurate prediction up to two and three weeks to give a large window of preparation in case of a surge in virus transmission. We investigate the stability of the prediction and its accuracy using bi-weekly predictions during the last trimester of 2020 and 2021. Using data from 2020, we show that understanding and correcting for the daily reporting structure of cases in the different countries is key to accomplish accurate predictions. Furthermore, we found that filtering out predictions that are highly unstable to changes in the parameters of the model, which are roughly 20%, reduces strongly the number of predictions that are way-off. The method is then tested for robustness with data from 2021. We found that, for this data, only 1–2% of the one-week predictions were off by more than 50%. This increased to 3% for two-week predictions, and only for three-week predictions it reached 10%., Te research leading to these results received funding from Ayudas Fundación BBVA a proyectos investigación científca 2021 under the project BBVA: Epidemiological modeling of SARS-CoV-2 in a post-pandemic surveillance context: an open platform for mid-term scenarios and short-term predictions, and from grants 2021 SGR 00582 funded by Agència de Gestió d’Ajuts Universitaris i de Recerca, and PID-2022-139216NB-I00 funded by Ministerio de Ciencia e Innovación (MCIN/AEI/10.13039/501100011033) and by ‘ERDF: A way of making Europe’, by the European Union., Peer Reviewed, Postprint (published version)
