Whole genome semiconductor based sequencing of farmed European sea bass (Dicentrarchus labrax) Mediterranean genetic stocks using a DNA pooling appro…
2016
European sea bass (Dicentrarchus labrax) is an important marine species for commercial and sport fisheries and aquaculture production. Recently, the European sea bass genome has been sequenced and assembled. This resource can open new opportunities to evaluate and monitor variability and identify variants that could contribute to the adaptation to farming conditions. In this work, two DNA pools constructed from cultivated European sea bass were sequenced using a next generation semiconductor sequencing approach based on Ion Proton sequencer. Using the first draft version of the D. labrax genome as reference, sequenced reads obtained a total of about 1.6 million of single nucleotide polymorp…
Towards understanding nonmanuality : A semiotic treatment of signers’ head movements
2019
This article discusses a certain type of nonmanual action, signers’ head movements, from a semiotic perspective. It presents a typology of head movements and their iconic, indexical and symbolic features based on Peircean and post-Peircean semiotics. The paper argues for the view that (i) indexical strategies are very prominent in head movements, (ii) iconic features are most evident in enacting, while non-enacting description is less common, (iii) symbolic types for tokens are infrequent, although some movements—such as nodding and shaking the head—may become more conventional or schematized, and (iv) different types of head movements involve different proportions of iconicity, indexicalit…
The Semiotics of Test Design: Conceptual Framework on Optimal Item Features in Educational Assessment Across Cultural Groups, Countries, and Languages
2021
This paper offers a conceptual framework on test design from the perspective of social semiotics. Items are defined as arrangements of features intended to represent information, convey meaning, and capture information on the examinees’ knowledge or skills on a given content. The conceptual framework offers a typology of semiotic resources used to create items and discusses item representational complexity—the multiple ways in which the semiotic resources of an item are related to each other—and item semiotic alignment—the extent to which examinees share cultural experience encoded by items. Since the ability to make sense of items is shaped by the examinees’ level of familiarity with the s…
La saisie esthétique, transformation non narrative de la subjectivité
2017
Abstract Post-Greimassian semiotics has worked toward a return to phenomenology, with the aim of studying the sensorial dimension and the body. Most of this research, however, has all but forgotten Greimas’s last book, De imperfection (1987), in which he proposes an original version of Merleau-Ponty’s philosophy with the notion of the aesthetic grasp. I propose to reconsider this almost abandoned notion, both from a theoretical point of view (a new version of the catharsis of philosophical aesthetics) and from the vantage of textual descriptions (the short story “The Naked Bosom” by Italo Calvino and the movie Ratatouille).
Study of J/ψ Production in Jets
2017
The production of $J/\psi$ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the $J/\psi$ meson, $z \equiv p_{\rm T}(J/\psi)/p_{\rm T}({\rm jet})$, is measured using jets with $p_{\rm T}({\rm jet}) > 20$ GeV in the pseudorapidity range $2.5 < \eta({\rm jet}) < 4.0$. The observed $z$ distribution for $J/\psi$ mesons produced in $b$-hadron decays is consistent with expectations. However, the results for prompt $J/\psi$ production do not agree with predictions based on fixed-order non-relativistic QCD. This is the first measurement o…

"Keskiluokkaistuva kansakoulunopettajisto" : Jyväskylän opettajaseminaarin opiskelijoiden kulttuurisosiaaliset taustat seminaariyhteisössä vuosina 19…
2016
Tässä tutkimuksessa selvitän Jyväskylän kansakouluopettajaseminaarin opiskelijoiden kulttuurisosiaalisia taustoja sekä niiden ilmentymistä seminaarin opetuksessa 1920- ja 1930-luvuilla. Kulttuurisosiaalisella taustalla tarkoitan opiskelijoiden sosioekonomista asemaa ennen seminaariin tuloa. Kulttuurisosiaalisen taustan muodostavat opiskelijan sosiaalinen tausta, taustakoulutus sekä se, miltä paikkakunnalta hän on kotoisin. Sosiaalisella taustalla tarkoitetaan tutkimuksessa opiskelijan perhetaustaan pohjautuvaa yhteiskunnallista sosiaalista statusta. Tutkimuksessa sukupuolella on tärkeä osa tarkastelunäkökulmassa, sillä seminaari oli jaettu nais- ja miesosastoon koko seminaarin toiminnan aja…
Frame-related Sequences in Chains and Scales of Hilbert Spaces
2022
Frames for Hilbert spaces are interesting for mathematicians but also important for applications in, e.g., signal analysis and physics. In both mathematics and physics, it is natural to consider a full scale of spaces, and not only a single one. In this paper, we study how certain frame-related properties of a certain sequence in one of the spaces, such as completeness or the property of being a (semi-) frame, propagate to the other ones in a scale of Hilbert spaces. We link that to the properties of the respective frame-related operators, such as analysis or synthesis. We start with a detailed survey of the theory of Hilbert chains. Using a canonical isomorphism, the properties of frame se…
Solid-state mechanochemical synthesis of multinary metal halide semiconductors for optoelectronics: From powder to thin film
2020
En la última década, las perovskitas de haluro de plomo, así como otros haluros de metales múltiples, incluidas las alternativas sin plomo, han demostrado ser materiales prometedores para su uso en optoelectrónica. Por lo tanto, se buscan activamente nuevas formas de producir semiconductores de alta pureza a gran escala. Por tanto, el objetivo principal de esta tesis doctoral es el desarrollo de perovskitas y semiconductores relacionados utilizando métodos sin disolventes. Además, con la perspectiva del uso de dichos materiales en optoelectrónica a escala industrial, el foco está puesto en trabajar con materiales benignos para el desarrollo de alternativas a las perovskitas tóxicas. La sínt…
Bloque detector PET basado en cristales monolíticos y fotomultiplicadores de silicio
2017
La tomografía por emisión de positrones (PET) es una técnica de imagen médica, encuadrada en la medicina nuclear, consistente en la generación de imágenes a partir de la detección de radiación gamma resultante de la aniquilación de positrones, emitidos por un radiotrazador, con los electrones de tejidos circundantes. Las imágenes PET son de tipo funcional, lo que permite la observación y estudio de procesos fisiológicos, sin embargo, se ha probado que la integración de estos escáneres con otros sistemas de imagen médica que proporcionen imágenes de carácter anatómico mejora notablemente las prestaciones clínicas de ambos equipos. Este tipo de equipos multimodales se conocen como sistemas hí…
