Novel and low-cost temperature compensation technique for piezoresistive pressure sensors

Repositorio: Recercat. Dipósit de la Recerca de Catalunya
Reverter Cubarsí, Ferran, Horak, Goran, Bilas, Vedran, Gasulla Forner, Manuel

This paper proposes a low-cost technique to compensate for the temperature dependence of piezoresistive pressure sensors configured in a Wheatstone bridge. The sensor is treated as a resistive circuit and three equivalent resistances are measured by setting appropriately the bridge terminals. One of these equivalent resistances depends on temperature but not on pressure and, hence, it can be used to compensate for the temperature dependence of the output parameter. In such a way, neither data..., Postprint (published version)

A complete characterization of the setup is performed and a comparison of the performance of each DSLM imaging modality is presented using in vivoCaenorhabditis elegans samples. We found that the use of Bessel beam nonlinear excitation results in better image contrast over a wider field of view., This work is supported by the Generalitat de Catalunya grant 2009-SGR-159, the Spanish government grants TEC2009-09698 and SAF2008-00211, the EU project STELUM (FP7-PEOPLE-2007-3-1-IAPP, 217997), the Swiss National Science Foundation (SNSF) Sinergia project grant CRSII3_125447, the FP7-NMP VIBRANT project grant CP-IP 228933-2, the NoE P4L and Laserlab optobio.

Neural, endocrine, and immune stress mediators are hypothesized to increase risks of diverse chronic diseases, including arthritis. Retrospective data from the World Mental Health Surveys (N=18,309) were employed to assess whether adult onset of arthritis was associated with childhood adversities and early onset psychological disorder. Cox proportional hazard models assessed the association of number of childhood adversities and the presence of early onset psychological disorder with arthritis..., These activities were supported by the United States National Institute of Mental Health (R01MH070884), the John D. and Catherine T.

Subtyping of primary aldosteronism in the AVIS-2 study: assessment of selectivity and lateralization

Repositorio: Recercat. Dipósit de la Recerca de Catalunya
Rossitto, Giacomo, Oliveras, Anna, Rossi, Gian Paolo

Context: Adrenal venous sampling (AVS) is the key test for subtyping primary aldosteronism (PA), but its interpretation varies widely across referral centers and this can adversely affect the management of PA patients. Objectives: To investigate in a real-life study the rate of bilateral success and identification of unilateral aldosteronism and their impact on blood pressure outcomes in PA subtyped by AVS. Design and settings: In a retrospective analysis of the largest international registry...

Bitterness is perceived in humans by 25 subtypes of bitter taste receptors (hTAS2R) that range from broadly tuned to more narrowly tuned receptors. hTAS2R5 is one of the most narrowly tuned bitter taste receptors in humans. In this study, we review the literature on this receptor and show there is no consensus about its role. We then compare the possible role of hTAS2R5 with that of the proteins of the TAS2R family in rat, mouse, and pig. A phylogenetic tree of all mammalian TAS2R domain-..., This research was funded by MCIN/AEI/10.13039/501100011033/FEDER “Una manera de hacer Europa”, grant number AGL2017-83477-R, C.

Bisiada, Mario

This conceptual article argues that class is a major factor in the social division and polarisation after the Covid‐19 pan‐ demic. Current discourse and communication analyses of phenomena such as compliance with measures and vaccine hesitancy seek explanations mainly in opposing ideological stances, ignoring existing structural inequalities and class rela‐ tions and their effects on people’s decisions. I approach social cohesion in the Covid‐19 pandemic through the theories of epidemic..., This work has benefited from funding received as part of the project Frames and Narratives of Translation and of Migration in Europe, funded by the Spanish Ministry for Science, Innovation and Universities (MCIU) and the Agencia Estatal de Investigación (AEI), with Grant No. PID2019–107971GA‐I00.



Comparison of the effect of two hybrid models of problem-based learning implementation on the development of transversal and research skills and the learning experience

Carrió, Mar, Baños i Díez, Josep Eladi, Rodríguez Fabià, Gemma, 1991-

Problem-based learning (PBL) provides an encouraging learning environment to develop transversal and research thinking skills. However, how PBL is implemented into a curriculum can be critical for achieving these outcomes. This study compares two hybrid PBL implementation models applied in a health sciences school: a PBL-module integrated into the subjects of a traditional curriculum and full interdisciplinary PBL-courses. 651 students were involved, with 330 taking the PBL-module and 277...

Two approaches to the semantic decomposition of change of state verbs, how they differ, and why it matters

Repositorio: Recercat. Dipósit de la Recerca de Catalunya
McNally, Louise, 1965-

In this paper, I contrast two broad decompositional approaches to verb semantics. One, especially associated with David Dowty, involves translating verbs using a set of precisely interpreted primitive predicates such as CAUSE and BECOME, in order to facilitate semantic generalizations such as patterns of entailment between sentences. Another, with multiple origins in both temporal semantics and theories of the syntax/semantics interface (including, notably, work by Pustejovsky and Piñón),...

López Fernández-Sesma, Lolo

Treball de fi de grau en Publicitat i Relacions Públiques, Tutor: Arnau Roig Mora, Este proyecto pretende usar el prisma de la hauntología creada por Derrida, desarrollada por Fisher y aplicada por Gorostizu a la música electrónica para analizar cómo es la escena, qué factores sociológicos han influido en su desarrollo, y cómo estos determinan el modo en el que se presenta en la actualidad, con un enfoque en lo queer y los espacios para las disidencias. Quizá por experiencia personal, quizá por justicia social.
