Residual a posteriori error estimation for frictional contact with Nitsche method
2023
We consider frictional contact problems in small strain elasticity discretized with finite elements and Nitsche method. Both bilateral and unilateral contact problems are taken into account, as well as both Tresca and Coulomb models for the friction. We derive residual a posteriori error estimates for each friction model, following [Chouly et al, IMA J. Numer. Anal. (38) 2018, pp. 921-954]. For the incomplete variant of Nitsche, we prove an upper bound for the dual norm of the residual, for Tresca and Coulomb friction, without any extra regularity and without a saturation assumption. Numerical experiments allow to assess the accuracy of the estimates and their interest for adaptive meshing …
Further development of integrated threat theory and intergroup contact: a reply to Aberson (2015)
2016
ABSTRACTThis essay furthers a dialogue about the theoretical and statistical merits of Croucher's [(2013). Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62] study exploring the relationships between threat from an immigrant group, belief that an immigrant wants to assimilate, and intergroup contact. Key points of divergence include assertions that (a) the relationships in the original piece are counter to previous literature/relationships, (b) the correlations presented are implausible, (c) the magnitude of the relationships is too strong, and (d) the manuscript has “odd” multiple regr…
Manejo de schwannoma vestibular con radiaciones : experiencia del IVO
2013
A partir de la década de los 70, nace la radiocirugía (RC) como tratamiento alternativo a la cirugía convencional en el tratamiento de los schwannomas vestibulares(SV). Poco a poco dicha técnica, ha ido desbancando a la microcirugía alcanzando cifras del 58 % de tratamientos de RC frente a la cirugía convencional. En el presente estudio analizamos el resultado de 167 tumores tratados con radiaciones (bien con dosis única (RC) o con dosis fraccionada, RT Estereotáctica Fraccionada (RTEF), determinando el control local y las complicaciones como tratamiento del SV. Analizamos los resultados en función de la tecnología utilizada para tratarlos, bien colimadores cilíndricos o bien micromutilámin…

MutSa expression predicts a lower disease-free survival in malignant salivary gland tumors:an immunohistochemical study
2021
Appropriate DNA replication is vital to maintain cell integrity at the genomic level. Malfunction on DNA repair mechanisms can have implications related to tumor behavior. Our aim was to evaluate the expression of key complexes of the DNA mismatch-repair system MutS? (hMSH2-hMSH6) and MutS? (hMSH2-hMSH3) in a panel comprising the most common benign and malignant salivary gland tumors (SGT), and to determine their association with disease-free survival. Ten cases of normal salivary gland (NSG) and 92 of SGT (54 benign and 38 malignant) were retrieved. Immunohistochemistry was performed for hMSH2, hMSH3, hMSH6. Scanned slides were digitally analyzed based on the percentage of positive cells w…
Mentalizing eye contact with a face on a video : Gaze direction does not influence autonomic arousal
2018
Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not …
Social engagement from childhood to middle age and the effect of childhood socio-economic status on middle age social engagement: results from the Na…
2016
ABSTRACTSocial engagement has powerful effects on wellbeing, but variation in individual engagement throughout the lifecourse is wide. The trajectories may differ by gender and be affected by socio-economic status (SES). However, long-term development of social engagement is little studied and the effect of childhood SES on later-life social engagement remains obscure. We aimed to describe the social engagement development from childhood to middle age by gender and test the effect of childhood SES on middle age social engagement. Data (N=16,440, 51.3% male) are drawn from the on-going National Child Development Study, following British babies born in 1958. Social engagement was measured by …

Identity and Online Groups
2017
Questions related to identity have been central to discussions on online communication since the dawn of the Internet. One of the positions advocated by early Internet pioneers and scholars on computer-mediated communication was that online communication would differ from face-to-face communication in the way traditional markers of identity (such as gender, age, etc.) would be visible for interlocutors. It was theorized that these differences would manifest both as reduced social cues as well as greater control in the way we present ourselves to others. This position was linked to ideas about fluid identities and identity play inherent to post-modern thinking. Lately, the technological and …
Chasing Weak Forces: Hierarchically Assembled Helicates as a Probe for the Evaluation of the Energetics of Weak Interactions.
2017
London dispersion forces are the weakest interactions between molecules. Because of this, their influence on chemical processes is often low, but can definitely not be ignored, and even becomes important in cases of molecules with large contact surfaces. Hierarchically assembled dinuclear titanium(IV) helicates represent a rare example in which the direct observation of London dispersion forces is possible in solution even in the presence of strong cohesive solvent effects. Hereby, the dispersion forces do not unlimitedly support the formation of the dimeric complexes. Although they have some favorable enthalpic contribution to the dimerization of the monomeric complex units, large flexible…
