Real-world evidence of biologic treatments in psoriatic arthritis in Italy: results of the CHRONOS (EffeCtiveness of biologic treatments for psoriati…
2022
Abstract Background Biologics have demonstrated efficacy in PsA in randomized clinical trials. More evidence is needed on their effectiveness under real clinical practice conditions. The aim of the present work is to provide real-world evidence of the effectiveness of biologics for PsA in the daily clinical practice. Methods CHRONOS was a multicenter, non-interventional, cohort study conducted in 20 Italian hospital rheumatology clinics. Results 399 patients were eligible (56.9% females, mean (SD) age: 52.4 (11.6) years). The mean (SD) duration of PsA and psoriasis was 7.2 (6.9) and 15.3 (12.2) years, respectively. The mean (SD) duration of the biologic treatment under analysis was 18.6 (6.…

Kohteliaisuus S2-oppijoiden sähköposteissa
2015
Tässä tutkimuksessa perehdytään S2-oppijoiden sähköposteissa käytettyihin kohteliaisuuden ilmaisuihin ja selvitetään, vaikuttaako taitotaso tai vastaanottaja kohteliaisuuteen. Tutkimuksen teoreettinen viitekehys nojaa voimakkaasti Brownin ja Levinsonin kohteliaisuusteoriaan (1987) ja Gricen vuorovaikutuksen periaatteisiin (1891). Tutkimukseni aineisto on peräisin Topling-hankkeesta, joka pyrkii yhdistämään tutkimustietoa kielitaidon arvioinnista ja S2-oppijoiden oppimisesta. Olen rajannut Topling-hankkeen runsasta aineistoa niin, että tässä tutkimuksessa keskityn yläkoululaisten kirjoittamiin sähköposteihin, jotka ovat suunnattu kolmessa eri tehtävässä ystävälle, opettajalle ja verkkokauppa…
Hybrid heterostructures and materials based on transition metal dichalcogenides
2020
La irrupción de los nanomateriales en la vida moderna es un claro indicador del avance científico. El diseño de materiales a la carta permite establecer un control preciso sobre las propiedades finales de estos. El objetivo principal que ha motivado la presente Tesis es la combinación y funcionalización de láminas de MoS2 ultrafinas químicamente exfoliadas (ce-MoS2) con diferentes sistemas de base molecular. La Tesis se divide en los siguientes Capítulos: Capítulo I: En primer lugar, se introducen brevemente los nanomateriales. En segundo lugar, se describen los materiales bidimensionales (2D). A continuación, se detallan algunos aspectos generales de los dicalcogenuros de metales de transi…
Model-assisted ultrasonic calibration using intentionally embedded defects for in-process weld inspection
2021
Abstract Automated in-process Non-Destructive Testing (NDT) systems are rapidly gaining traction within the manufacturing industry as they reduce manufacturing time and costs. When considering calibration and verification of such systems, creating defects of known geometry and nature during the deposition of a weld can: (I) help examine the capability of the automated system to detect and characterise defects, (II) be used to form a database of signals associated with different defect types to train intelligent defect classification algorithms, and (III) act as a basis for in-process gain calibration during weld inspection at high temperatures, where the ultrasound beam can be skewed as a r…
Performance Analysis of Sweep-Spread Carrier (S2C) Modulation for Underwater Communications
2022
In the last decades, underwater acoustic communications have seen a growing development with a variety of research as well as commercial applications, dealing with channel distortions, multipath and Doppler effects typical underwater channels. A very robust modulation able to guarantee connectivity in harsh environments (where spectral efficient solutions such as OFDM can be prevented) is the so called sweep-spread carrier (S2C) modulation, which is based on the usage of a linearly time-varying carrier. Underwater modems based on S2C modulations have been patented and successfully adopted in real-world deployments. In this paper, we analyze the performance of S2C both in simulation and infi…
Las imágenes de los perpetradores, los artefactos de los perpetradores: el archivo nómade de Tuol Sleng (S-21)
2016
Este ensayo analiza la producción y circulación de las fotografías de las fichas de dete-nidos tomadas por la maquinaria del Jemer Rojo en el centro de tortura S-21 (Phnom Penh). Al momento de tomar las fotografías, estas jugaron un rol esencial en el proceso de identificación, represión y asesinato de quienes eran considerados enemigos del régimen de la Kampuchea Democrática (1975-1979). No obstante, tras la caída de los Jemeres Rojos, estas fotografías fueron utilizadas para denunciar a quienes las habían tomado, como si las imágenes no conservaran rastros de su función original y fueran reversibles. Por esto las trasladaron desde los museos y galerías de arte a los escena-rios, de los li…
A note on the Lawrence-Krammer-Bigelow representation
2002
A very popular problem on braid groups has recently been solved by Bigelow and Krammer, namely, they have found a faithful linear representation for the braid group B_n. In their papers, Bigelow and Krammer suggested that their representation is the monodromy representation of a certain fibration. Our goal in this paper is to understand this monodromy representation using standard tools from the theory of hyperplane arrangements. In particular, we prove that the representation of Bigelow and Krammer is a sub-representation of the monodromy representation which we consider, but that it cannot be the whole representation.
Identification et caractérisation du récepteur à la flagelline (VvFLS2) et recherche du récepteur aux chito-oligosaccharides chez la vigne
2014
Pattern-recognition receptors (PRRs) play a key role in plant immunity by assuring recognition of microbe-associated molecular patterns (MAMPs), signature of microbial presence. MAMP perception constitutes the first layer of pathogen detection and activates defense mechanisms that aim to block the intruder. This study brings an insight into how grapevine (Vitis vinifera) perceives two MAMPs: the flagellin-derived flg22 peptide and chitin, which are conserved motifs occurring over the whole bacterial and fungal classes, respectively. This study analyzed MAMP-triggered early signaling events, defense gene expression and also the efficiency of elicited defense against gray mold and downy milde…
