Evolving the Knowledge Space: Towards a Selection Dynamics Model of Patent Classes

The current report seeks to understand the selection dynamics of patent classes (CPCs) in Europe by employing the methodology developed by Acemoglu et al. (2016) to predict future patenting. Their research focuses on citation networks measuring the knowledge flows across technologies and uses theses to estimate future volumes of patents per CPC during 1995-2004 in the United States. In our current analysis we replicate their results using the European patent database for the years 2005-2014, and likewise demonstrate that the innovation networks have significant predictive power over future patenting in Europe. Furthermore, we improve their methodology by accounting for more complex interactions between CPCs. Finally, we discuss their implications for developing a selection-dynamics model grounded in evolutionary theory

Exploring alternative symmetry breaking mechanisms at the LHC with 7, 8 and 10 TeV total energy

In view of the annnouncement that in 2012 the LHC will run at 8 TeV, we study the possibility of detecting signals of alternative mechanisms of ElectroWeak Symmetry Breaking, described phenomenologically by unitarized models, at energies lower than 14 TeV. A complete calculation with six fermions in the final state is performed using the PHANTOM event generator. Our results indicate that at 8 TeV some of the scenarios with TeV scale resonances are likely to be identified while models with no resonances or with very heavy ones will be inaccessible, unless the available luminosity will be much higher than expected

Hops, Skip and a Jump: The Regional Uniqueness of Beer Styles

Perhaps more than any other product, beer evokes its place of origin. Part of what makes every pint of Guinness or stein of Paulaner so memorable is what sets them apart and gives them their unique "taste of place." This chapter explores the geographical differentiation of beer. To do so, we collect data on regional beer recipes, styles, and ingredients from a homebrewing website. We then employ Evolutionary Economic Geography (EEG) methods and create weighted co-occurrence networks for the ingredients within each style. We use these networks to identify which ingredients are most important to each beer style, measure a style’s robustness, and compare differences between geographically close and distant styles. While previous literature focuses on the related diversification of regions, we use these methods to examine the differences within the same product and across many regional styles and flavours. Combining the EEG methods with this unique ingredients dataset, we show that almost all beer styles rely on only a handful of key ingredients. Yet some regional beers are more robust than others due to readily available substitute ingredients in their region. Likewise, we demonstrate that styles originating in close geographic proximity are more similar in their use of ingredients.Item will be publihsed as a book chapter -- update details accordingly once published. 2023-06-1

How well can the LHC distinguish between the SM light Higgs scenario, a composite Higgs and the Higgsless case using VV scattering channels?

A complete parton level analysis of ll + four jets l = e,mu and 3lv + two jets production at the LHC is presented, including all processes at order \ordEW, \ordQCD and \ordQCDsq when appropriate. The infinite Higgs mass scenario, which is considered as a benchmark for strong scattering theories and is the limiting case for composite Higgs models, and one example of a model incorporating a Strongly Interacting Light Higgs are confronted with the Standard Model light Higgs predictions. This analysis is combined with the results in the lv + four jets channel presented in a previous paper, in order to determine whether a composite Higgs signal can be detected as an excess of events in boson--boson scattering.Comment: Introduced some representative Feynman diagrams. Rearranged section 4. Typos fixed. Published in JHE

Surgical multicenter collaborative studies: ¿What happen in Latin America?

Antecedentes: GlobalSurg es un grupo internacional de investigadores que tiene como propósito la conducción y la diseminación de robustos estudios colaborativos, internacionales y multicéntricos. Objetivo: Exponer las estrategias necesarias y las barreras encontradas en la conducción de estudios multicéntricos masivos en cirugía. Método: Durante el segundo semestre del año 2020 se llevó a cabo el estudio Surg-Week Prospective International Cohort Study, hasta la fecha el estudio internacional más grande en el campo de la cirugía, con 141,582 pacientes incluidos. Un total de 4975 miniequipos, de uno a cinco integrantes, recopilaron datos de 116 países de todos los continentes. Resultados: La creación de un sitio web oficial del estudio, reportes con información relevante vía e-mail o grupos vía WhatsApp, conformación de un comité de diseminación del protocolo, dictado de webinars sobre publicaciones recientes del equipo, designación de líderes nacionales e internacionales, y la divulgación por medio de sociedades, fueron las estrategias utilizadas para el desarrollo de la investigación. Sin embargo, las barreras detectadas para llevar a cabo el estudio multicéntrico fueron variadas. Conclusiones: Los trabajos colaborativos permiten establecer redes entre diferentes profesionales con el fin de mejorar la calidad de la gestión, las políticas sanitarias y la atención a los pacientes en tiempos de constante cambio.Background: GlobalSurg is an international group of researchers whose purpose is to conduct and disseminate robust collaborative, international and multicenter studies. Objective: To expose the necessary strategies and the barriers crossed in conducting massive multicenter studies in surgery. Method: During the second semester of 2020, the study Surg-Week Prospective International Cohort Study was carried out. Surg-Week has been the largest international study in the field of surgery to date, with 141,582 patients included. A total of 4975 mini-teams, of between 1 and 5 members, collected data from 116 countries on all continents. Results: The creation of an official website for the study, reports with relevant information via email or groups via WhatsApp, formation of a Dissemination Committee of the protocol, delivery of webinars on recent team publications, appointment of leaders at the national and international level, and outreach through partnerships, were the strategies used for the development of the research. However, the barriers turned out to involve different aspects. Conclusions: Collaborative work allows establishing networks between different professionals with the goal of improving the quality of management, health policies and care of our patients in a timely manner of constant change
