An unusual association of left‐sided gastroschisis and persistent right umbilical vein

2018

Key Clinical Message Gastroschisis is a full‐thickness congenital abdominal wall defect usually occurring to the right of the umbilicus. About twenty cases of left‐sided gastroschisis have been reported, without reference to the laterality of the umbilical vein. This first case highlights the importance of considering and reporting this association by the perinatal team.

Sports as a motivation to study English : young athletes and the L2 motivational self system

2013

Tutkimuksen lähtökohtana oli Zoltán Dörnyein uusi motivaatioteoria, joka koostuu oppijoiden tulevaisuuden minäkuvista sekä aiemmista kokemuksista kohdekieleen liittyen. Kyseistä teoriaa ei ole vielä laajalti käytetty tutkimuksessa, ja suomalaiset kieltenoppijat ovat vielä varsin uusi kohderyhmä kyseiselle teorialle. Tutkimuksen tarkoituksena oli selvittää nuorten urheilijoiden suhtautumista englantiin ja sen tärkeyteen. Tutkimuksessa tutkittiin urheilijoiden 1) yleisiä asenteita englantia kohtaan, 2) heidän urheiluun ja englantiin liittyviä tulevaisuuden minäkuvia, sekä 3) heidän aiempia urheiluun liittyviä kokemuksia englannin käytöstä. Urheilijat ovat uusi kohderyhmä motivaatiotutkimukses…

Optical flow estimation from multichannel spherical image decomposition

2011

International audience; The problem of optical flow estimation is largely discussed in computer vision domain for perspective images. It was also proven that, in terms of optical flow analysis from these images, we have difficulty distinguishing between some motion fields obtained with little camera motion. The omnidirectional cameras provided images with large filed of view. These images contain global information about motion and allow to remove the ambiguity present in perspective case. Nevertheless, these images contain significant radial distortions that is necessary to take into account when treating these images to estimate the motion. In this paper, we shall describe new way to comp…

Individualized Template MRI Is a Valid and Reliable Alternative to Individual MRI for Spatial Tracking in Navigated TMS Studies in Healthy Subjects

2020

Objectives: Navigated transcranial magnetic stimulation (nTMS) provides significant benefits over classic TMS. Yet, the acquisition of individual structural magnetic resonance images (MRIindividual) is a time-consuming, expensive, and not feasible prerequisite in all subjects for spatial tracking and anatomical guidance in nTMS studies. We hypothesize that spatial transformation can be used to adjust MRI templates to individual head shapes (MRIwarped) and that TMS parameters do not differ between nTMS using MRIindividual or MRIwarped.Materials and Methods: Twenty identical TMS sessions, each including four different navigation conditions, were conducted in 10 healthy subjects (one female, 2…

Attēla kvalitātes ietekme uz acs struktūru izvērtēšanu foto-diagnostikā

2021

Darba mērķis bija izpētīt 18 samazinātas kvalitātes spraugas lampas attēlu, kuros attēloti acu priekšējo daļu struktūras, ietekmi uz 5 profesionāļu atzinumiem. Attēli, kas sadalīti 3 6 attēlu komplektos trim samazināšanas filtriem, izplūdums (1-6), troksnis (7-12) un kontrasts (13-18), tika parādīti datora ekrānā un salīdzināti ar oriģinālajiem attēliem. Rezultāti tika saskaņoti ar īsto attēla diagnozi un novērtēti 3 punktu sistēmā, pareizs atradums: 1 un 0,5 (daļēji) punkti, nepareizs vai nav atrasts: 0 punkti. Tika reģistrēti 53 punkti no 90 (58% pareizi un 41% nepareizi). Rezultāti liecina, ka attēla kvalitātes samazināšana būtiski neietekme…

« Recyclages audiovisuels dans le documentaire de création contemporain »

2022

La numérisation à grande échelle et la mise en ligne des fonds d’archives filmiques, la prolifération d’images sur internet, notamment depuis l’apparition de YouTube en 2005, ou encore les techniques numériques de traitement des images ont favorisé l’essor des films de found footage –littéralement enregistrements ou images trouvés–, une modalité qui est devenue une tendance marquante du documentaire contemporain. Certaines de ces œuvres, parfois constituées intégralement d’images de « seconde main » (Blümlinger, 2013), au-delà de la reconnaissance critique et de l’intérêt des chercheurs, ont connu le succès en salles ou sur les plateformes et ont été projetées et récompensées dans les festi…

Verità e menzogna dei simboli

2008

Cosa sono e come funzionano i simboli? Quali sono i meccanismi di trasmissione dell’immaginario, i suoi spazi e la sua rilevanza sociale? Quali il ruolo e il perimetro del sacro, del mito, del rito, della magia e della religione in certi ambiti, erroneamente percepiti come marginali, della società contemporanea? Quali le strategie di trasmissione della memoria culturale e i processi di produzione e riproduzione dell’identità comunitaria? I saggi riuniti in questo volume cercano di fornire alcune risposte a questi interrogativi confrontandosi con la pervasiva, sebbene non di rado occulta, dialettica culturale tra immanenza e trascendenza e indagando sulle dinamiche psicologiche e sociali del…

Visibility without voice: Media witnessing irregular migrants in BBC online news journalism

2016

In the analysis of journalistic representation of irregular migration to Europe, rather little attention is given to the variation of modes and genres of journalism. Most studies focus on text in ‘old media’ and the news genre. This article analyses affordances of different modalities and genres of online journalism in framing irregular migrants. Media framing in BBC online news coverage of a mediatised conflict in Spain, defined as a ‘migration crisis’, is analysed with multimodal social semiotics. While mediation makes global audiences witness tragedies at Europe's borders and online journalism affords more voice and deliberation for migrant sources, the frames of threat and victim domina…

Skeleton-Based Multiview Reconstruction

2016

International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
