First measurement of the Sivers asymmetry for gluons using SIDIS data
2017
The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal asymmetry of hadrons produced in semi-inclusive deep inelastic scattering of leptons off transversely polarised nucleon targets, and it turned out to be non-zero for quarks. In this letter the evaluation of the Sivers asymmetry for gluons in the same process is presented. The analysis method is based on a Monte Carlo simulation that includes three hard processes: photon-gluon fusion, QCD Compton scattering and leading-order virtual-photon absorption process. The Sivers asymmetries of the three processes are simul…
Complexus adhaerentes, a new group of desmoplakin-containing junctions in endothelial cells: II. Different types of lymphatic vessels.
1994
Abstract In diverse mammalian species, including (man, cow and rat) the very flat endothelial cells of lymphatic vessels of various organs, including the retothelial meshwork of sinus of lymph nodes, are connected by zonula -like plaque-bearing junctions which differ from the similarly structured junctions of blood vessel endothelia by the presence of desmoplakin or an as yet unknown but closely related plaque protein. These extended junctions, which also contain plakoglobin but none of the presently known desmogleins and desmocollins, are therefore different from the spot-like desmosomes ( maculae adhaerentes ) present in epithelia, myocardium and dendritic reticulum cells of lymphatic fol…
El potencial cohesionador de les Falles de la Secció Especial 1981-2020 al voltant dels valors conservadors i tradicionals
2021
En aquest treball es planteja "El potencial cohesionador de les falles de la Secció Especial 1981-2020 al voltant de valors conservadors i tradicionals". Aquest estudi mostra com les falles tenen un potencial cohesionador molt elevat i constitueixen un factor de creació d’identitat molt potent. No obstant, es constata que el tradicionalisme i el conservadorisme no son valors únics dintre de la Secció Especial. L’existència de discursos i ideologies alternatives, associades al progressisme, es mostra en una minoria de falles, així com el conservadorisme i el tradicionalisme faller es mostrarien com hegemònics, però no com únics. En aquest estudi és fonamental, ja que es centra en l’element c…
Desmosomes: interconnected calcium-dependent structures of remarkable stability with significant integral membrane protein turnover
2002
Desmosomes are prominent cell adhesion structures that are major stabilizing elements, together with the attached cytoskeletal intermediate filament network, of the cytokeratin type in epithelial tissues. To examine desmosome dynamics in tightly coupled cells and in situations of decreased adhesion, fluorescent desmosomal cadherin desmocollin 2a (Dsc2a) chimeras were stably expressed in human hepatocellular carcinoma-derived PLC cells (clone PDc-13) and in Madin-Darby canine kidney cells (clone MDc-2) for the continuous monitoring of desmosomes in living cells. The hybrid polypeptides integrated specifically and without disturbance into normal-appearing desmosomes that occurred in associati…
Loneliness and interaction ritual theory: failed interaction chains among Finnish university students
2021
This article relates loneliness to interaction ritual theory, understanding loneliness in terms of problematic microinteractional dynamics. The advantage of interaction ritual theory is that it extends our understanding of the issue of the psychologised self and related questions such as how loneliness feels or is experienced. Loneliness is here defined as a response to interaction representing relational understanding of emotions. Interaction ritual theory is interested in the emotional consequences that individuals experience from successful or unsuccessful interaction rituals. Loneliness in this view represents a state in which the individual is denied access to rewarding aspects of inte…

Orbital volume and shape in Treacher Collins syndrome
2018
Orbito-palpebral reconstruction is a challenge in Treacher Collins syndrome (TCS). This study investigates orbital phenotypes in TCS using cephalometry and orbital shape analysis. Eighteen TCS and 52 control patients were included in this study, using the Dr Warehouse database. Orbital cephalometry was based on 20 landmarks, 10 planes, 16 angles, and 22 distances. Orbits were segmented. Registration-based, age-specific mean models were generated using semi-automatic segmentation, and aligned and compared using color-coded distance maps - mean absolute distance (MAD), Hausdorff distance (HD), and Dice similarity coefficient (DSC). Symmetry was assessed by mirroring and DSC computing. Central…
Cholesteatoma of the hypotympanum in a patient with Treacher Collins syndrome
2014
In the present article we report a cholesteatoma of the hypotympanum extending to the jugular foramen in a 16-year-old male with Treacher Collins syndrome. Preoperative imaging excluded jugular paraganglioma and set the diagnosis of cholesteatoma. We discuss the operative treatment via a large hypotympanotomy and creation of an open hypotympanic cavity. To the authors' knowledge this is the first description of hypotympanal cholesteatoma with such an extension, being treated through this approach.
Collins and Sivers asymmetries for pions and kaons in muon-deuteron DIS
2008
The measurements of the Collins and Sivers asymmetries of identified hadrons produced in deep-inelastic scattering of 160 GeV/c muons on a transversely polarised 6LiD target at COMPASS are presented. The results for charged pions and charged and neutral kaons correspond to all data available, which were collected from 2002 to 2004. For all final state particles both the Collins and Sivers asymmetries turn out to be small, compatible with zero within the statistical errors, in line with the previously published results for not identified charged hadrons, and with the expected cancellation between the u- and d-quark contributions.
“There is something very pompous in his style”: an analysis of Mr Collins’ social missteps in Pride and Prejudice
2019
Kandidaatin tutkielmani käsittelee Jane Austenin rakastettua romaania Ylpeyttä ja Ennakkoluuloa (Pride and Prejudice) ja erityisesti siinä esiintyvää sivuhahmoa, Mr Collinsia. Tavoitteeni oli selvittää, miksi sekä lukijat että kirjassa olevat hahmot yleisesti pitävät kyseistä hahmoa samanaikaisesti sietämättömänä sekä huvittavana. Keskityin siis löytämään mahdollisia kohteliaisuusrikkomuksia sekä niiden seurauksia Mr Collinsin ja muiden hahmojen dialogeista. Nämä rikkomukset selittävät hahmon huonon vastaanoton. Analysoin kolmea tärkeää kohtausta, joissa erityisesti korostuivat Mr Collinsin ja muiden hahmojen väliset väärinymmärrykset sekä Mr Collinsin aiheuttamat kiusalliset tilanteet. Näi…
