Probing the Higgs self-coupling through double Higgs production in vector boson scattering at the LHC

In this work we explore the sensitivity to the Higgs self-coupling λ in the production of two Higgs bosons via vector boson scattering at the LHC. Although these production channels, concretely W+W−→HH and ZZ→HH, have lower rates than gluon-gluon fusion, they benefit from being tree level processes, being independent of top physics and having very distinctive kinematics that allow us to obtain very clean experimental signatures. This makes them competitive channels concerning the sensitivity to the Higgs self-coupling. In order to give predictions for the sensitivity to this coupling, we first study the role of λ at the subprocess level, both in and beyond the Standard Model, to move afterwards to the LHC scenario. We characterize the pp→HHjj case first and then provide quantitative results for the values of λ that can be probed at the LHC in vector boson scattering processes after considering the Higgs boson decays. We focus mainly on pp→bb¯bb¯jj, since it has the largest signal rates, and also comment on the potential of other channels, such as pp→bb¯γγjj, as they lead to cleaner, although smaller, signals. Our whole study is performed for a center of mass energy of s=14TeV and for various future expected LHC luminositiesThis work is supported by the European Union through the ITN ELUSIVES H2020-MSCA-ITN-2015//674896 and the RISE INVISIBLESPLUS H2020-MSCA-RISE-2015//690575, by the CICYT through the projects FPA2016-78645-P, by the Spanish Consolider-Ingenio 2010 Programme CPAN (CSD2007-00042) and by the Spanish MINECO's “Centro de Excelencia Severo Ochoa” Programme under grant SEV-2016-0597.

Webrooming or showrooming, that is the question: explaining omnichannel behavioural intention through the technology acceptance model and exploratory behaviour

Purpose: This paper evaluates how the intention to develop webrooming or showrooming behaviour is affected by both the perceived usefulness and the perceived ease-of-use, as well as by the consumer's personal predisposition to exploratory information seeking and acquisition. Design/methodology/approach: The fashion retailing environment is more omni-channel than ever before. The two predominant omni-channel behaviours are webrooming and showrooming. Taking as its basis the technology acceptance model (TAM) and the concept of exploratory consumer behaviour. Findings: The results obtained from a sample of 847 apparel shoppers (462 webroomers and 385 showroomers) show that the higher perception of the usefulness and ease-of-use of omni-channel buying processes, the higher the intention to develop both webrooming and showrooming behaviours. Additionally, the perceived ease-of-use exerts an additional indirect effect on the intention of developing these omni-channel behaviours through perceived usefulness. Finally, exploratory information seeking and acquisition have a relevant influence on webrooming intentions, but not on showrooming. Originality/value: The authors' research contributes to the literature on consumer behaviour in the fashion sector by testing a model to explain the intentions of individuals to adopt webrooming and showrooming, incorporating different psychographic variables linked to the use of ICT and the development of an exploratory consumer behaviour

Immunobiology of Atherosclerosis: A Complex Net of Interactions

Cardiovascular disease is the leading cause of mortality worldwide, and atherosclerosis the principal factor underlying cardiovascular events. Atherosclerosis is a chronic inflammatory disease characterized by endothelial dysfunction, intimal lipid deposition, smooth muscle cell proliferation, cell apoptosis and necrosis, and local and systemic inflammation, involving key contributions to from innate and adaptive immunity. The balance between proatherogenic inflammatory and atheroprotective anti-inflammatory responses is modulated by a complex network of interactions among vascular components and immune cells, including monocytes, macrophages, dendritic cells, and T, B, and foam cells; these interactions modulate the further progression and stability of the atherosclerotic lesion. In this review, we take a global perspective on existing knowledge about the pathogenesis of immune responses in the atherosclerotic microenvironment and the interplay between the major innate and adaptive immune factors in atherosclerosis. Studies such as this are the basis for the development of new therapies against atherosclerosis.The authors’ research is supported by grants from the Instituto de Salud Carlos III (ISCIII) (PI17/01395; CPII16/00022) and EuroCellNet COST Action CA15214 with co-funding from the European Regional Development Fund (ERDF), “A way to build Europe,” and the Miguel Servet Program.

Geodetic network design and strategies followed for drilling a 25 km tunnel for high speed railway in Spain

During the last years several large high-speed railway tunnels have been built in Spain. To solve these projects, technical and scientific problems have been solved from the geodetic and surveying point of view. These studies have allowed us to set a methodology that optimizes the performance of this kind of works in the world of Civil Engineering. We have applied our studies to the Tunnels of Pajares that are the second longest ones in Spain with a total longitude of about 25 km. The studies summarize the design of the geodetic networks to support the guidance of the TBMs used as well as the election of the observations to be done, the instrumental to be used and the observation and computation procedures to be followed. A special emphasis has been taken into account for the treatment of the uncertainty of the coordinates, displacements and breakthrough obtained during the drilling tasks. The article shows the results obtained and the conclusions that can be followed in order to successfully complete a similar project

Corporal body adiposity (BAI) and abdominal volume (AVI) indices: Relationship with obesity scales in the working population

Objective: Obesity is a growing pandemic and body mass index (BMI) is insufficient to assess the risk of complications. Other estimates of adiposity are used.Materials and methods: Cross-sectional study in 193,462 workers. BMI, CUN-BAE (Clínica Universitaria de Navarra Body adiposity Estimator), Cordoba Equation (ECORE-BF), Relative Fat Mass (RFM), Metabolic Score for Visceral Fat (METS-VF) and Palafolls formula. Their correlation with body adiposity index (BAI) and abdominal volume (AVI) was estimated. SPSS 27.0 was used, considering statistical significance p<0.05.Results: With all scales AVI and BAI are higher in obesity. AVI is higher in men, except with METS-VF. BAI in women has higher values in all scales. The highest values of AVI and BAI are with METS-VF, the lowest with PALAFOLLS. There is a good correlation of BMI with AVI and BAI and with the RFM and METS-VF scales and a very good correlation with Palafolls, ECORE-BF and CUN BAE. AVI and BAI show good correlation with Palafolls, ECORE-BF and CUN BAE and very good correlation with RFM and METS-VF.Conclusions: AVI and BAI show differences in their values according to sex. With METS-VF, both indexes are higher in men and women. AVI and BAI show good correlation with BMI and RFM. With METS-VF very good correlation with AVI. With the rest of the scales BAI and AVI show moderate or good correlation. The simplicity of these formulas and of both indexes makes them recommendable in clinical practice

Utilización de la dendrogeomorfología como geoindicador para evaluar procesos de erosión

Use of dendrogeomorphology as geoindicator to assess erosion processes.Anatomical changes of exposed tree roots are a valuable tools to date erosion events. The roots of some tree species subjected to erosive events suffer changes allow to quantify such processes. A descriptive and quantitative study was conducted in Scots pine Pinus sylvestris L the Senda Schmidt, a popular trail located on the northern slope of the Sierra de Guadarrama (Central Iberian System, Spain). Measurement of significant parameters allowed the moment of exposure of the roots to be identified. These parameters were: a) width of the growth ring; b) number of cells per ring; c) percentage of latewood and d) diameter of cellular light in earlywood. A one-way analysis ANOVA was also carried out in order to establish statistically significant differences between homogeneous groups of measurements in preexposed and exposed roots

Response of Pinus sylvestris roots to sheet-erosion exposure: An anatomical approach

Anatomical changes of exposed tree roots are valuable tools to date erosion events, but the responses of diverse species under different types of erosion need still to be studied in detail. In this paper we analyze the histological changes that occur in roots of Scots pine (Pinus sylvestris L.) subjected to continuous denudation. A descriptive and quantitative study was conducted in the Senda Schmidt, a popular trail located on the northern slope of the Sierra de Guadarrama (Central Iberian System, Spain). Measurement of significant parameters allowed the moment of exposure of the roots to be identified. These parameters were: a) width of the growth ring; b) number of cells per ring; c) percentage of latewood and d) diameter of cellular light in earlywood. A one-way analysis ANOVA was also carried out in order to establish statistically significant differences between homogeneous groups of measurements in pre-exposed and exposed roots. Based on these analyses, Scots pine roots show a remarkable anatomical response to sheet-erosion exposure. Increased growth in the ring is accompanied by a slight reduction of the cell lumina of the earlywood tracheids. At the end of the ring, several rows of thick-walled tracheids define latewood tissue and visible annual borders very clearly. Furthermore, resin ducts often appear in tangential rows, increasing resin density in the tissue. All of these indicators made it possible to determine with precision the first year of exposure and to estimate precisely sheet erosion rates
