The ALICE Transition Radiation Detector: Construction, operation, and performance
2018
The Transition Radiation Detector (TRD) was designed and built to enhance the capabilities of the ALICE detector at the Large Hadron Collider (LHC). While aimed at providing electron identification and triggering, the TRD also contributes significantly to the track reconstruction and calibration in the central barrel of ALICE. In this paper the design, construction, operation, and performance of this detector are discussed. A pion rejection factor of up to 410 is achieved at a momentum of 1 GeV/$c$ in p-Pb collisions and the resolution at high transverse momentum improves by about 40% when including the TRD information in track reconstruction. The triggering capability is demonstrated both …

Search for pair-produced massive coloured scalars in four-jet final states with the ATLAS detector in proton–proton collisions at √s =7 TeV
2013
A search for pair-produced massive coloured scalar particles decaying to a four-jet final state is performed by the ATLAS experiment at the LHC in proton–proton collisions at √s = 7 TeV. The analysed data sample corresponds to an integrated luminosity of 4.6 fb[superscript −1]. No deviation from the Standard Model is observed in the invariant mass spectrum of the two-jet pairs. A limit on the scalar gluon pair production cross section of 70 pb (10 pb) is obtained at the 95 % confidence level for a scalar gluon mass of 150 GeV (350 GeV). Interpreting these results as mass limits on scalar gluons, masses ranging from 150 GeV to 287 GeV are excluded at the 95 % confidence level.
Measurements of the Absolute Branching Fractions of B± →k±Xc c
2020
A study of the two-body decays B±→XccK±, where Xcc refers to one charmonium state, is reported by the BABAR Collaboration using a data sample of 424 fb-1. The absolute determination of branching fractions for these decays are significantly improved compared to previous BABAR measurements. Evidence is found for the decay B+→X(3872)K+ at the 3σ level. The absolute branching fraction B[B+→X(3872)K+]=[2.1±0.6(stat)±0.3(syst)]×10-4 is measured for the first time. It follows that B[X(3872)→J/ψπ+π-]=(4.1±1.3)%, supporting the hypothesis of a molecular component for this resonance.
Tuhoisa influentsa tarttui leskipastorska Pihlin kotikirjastoon: pandemian vaikutus 1800-luvun perheen kirjakokoelmaan
2023
1800-luvulla kirjoilla oli esineinä vielä rahallista ja yhteiskunnalliseen statukseen liittyvää arvoa, ja omistajan kuolema aloitti yleensä vain uuden luvun kirjan elämässä. Tutkin kuolinpesien kirjakokoelmien kohtaloja käyttämällä esimerkkinä erästä 1800-luvun lopun tapausta, jossa leskipastorska Pihl antoi kotikirjastonsa kirjoja helsinkiläiselle Minerva-antikvariaatille myytäväksi. Mikrohistoriallinen esimerkki kertoo perheenjäsenen kuolemantapauksen vaikutuksesta eri sukupuolten ja sukupolvien kirjanomistukseen. Tarkastelen, miten säätyläisperheissä, kuten pappisperheissä, yhtäkkinen kuolema muutti kirjojen omistussuhteita, ja kuinka perheen sisällä miesten ja naisten suhtautuminen kirj…
Kirjoittamisen arkipäiväistäminen Pentti Saarikosken ja Mirkka Rekolan runoudessa
2014
Writing as Part of the Everyday in Pentti Saarikoski’s and Mirkka Rekola’s Poetry This article examines the processes of writing as part of the everyday in Pentti Saarikoski’s kuljen missa kuljen and Mirkka Rekola’s Ilo ja epasymmetria, both published in 1965. I argue that both collections make this process visible, and both authors thus actively participate in the discussion about poetry in the 1960s through their poetry. While Saarikoski’s poetry was appreciated as communicative, democratic poetry, Rekola’s writing was considered as old-fashioned modernist poetry – a characterization associated at the time also with Finnish-Swedish poetry. In this article, I show that despite the attitude…
Kuvitellut Pohjoismaat Viron presidenttien puheissa
2017
Pohjoismaisuus on ollut oleellinen osa Viron kuulumisen politiikkaa viimeisen parinkymmenen vuoden aikana. Artikkeli analysoi, miten ja missä tarkoituksessa maan kolme presidenttiä asemoivat puheissaan Viroa suhteessa Pohjoismaihin vuosina 1992–2016. Tulokset osoittavat, että pohjoismaisuus saa kuulumisen politiikassa moninaisia muotoja: Pohjoismaihin kuulumisen, sen rajalla tai naapurissa olemisen lisäksi aineistossa uudelleen määritellään myös Pohjoismaat yhteisönä visioimalla Itämeren alueelle sijoittuvaa dynaamista ja kehittyvää Pohjola-Baltia-kokonaisuutta.
In search of proper pronunciation: students’ practices of soliciting help during read-aloud
2018

 
 
 This ar cle examines Finnish L2 learners’ interactional practices of flagging trouble in pronouncing words when reading aloud texts in English. Using conversation analysis, it describes how students employ three repair initiaon techniques – direct requests, trying out, and aborting the reading – as methods through which they mobilize teachers’ help in the form of a model pronunciation of the target word. By describing the sequential and temporal unfolding of read-aloud, the article presents an empirical way of tracing those classroom practices that students employ to develop their pronunciation skills of English in Finland. CA-based methodology that focuses on the inter…
Studying religious music at the grassroots level: a look into the discourse practices of Christian metal bands online
2013
Religious issues are studied in various ways, most prominently by sociologists of religion. This paper suggests that in today’s world of globally intersecting webs of people, places, ideas and action, scholars and readers interested in religion will find themselves benefiting from cross-disciplinary approaches which help them to conceptualize and describe today’s phenomena at different levels. This paper describes how the emerging discipline of the sociology of language and religion may be applied to studying Christian metal bands’ discourse online. Although previous studies give a good idea of the structures, practices and tendencies in and related to Christian metal, little is reported on…
Activity typologies as a design model for the ubiquitous detection of daily routines
2018
Emerging technologies open up new visions and business potential for systems design and development in the areas of wellbeing and health. New technologies enable the detection of human performance and early changes in physical and cognitive functioning, making it possible to monitor an older person’s wellbeing. This kind of technology or service sets significant requirements for design, as design concepts must be able to capture the complexity of people’s daily lives in terms of activities and environments. Technology itself is “blind” unless designers can adapt it to human life. There is thus a distinct need for comprehensive design and development models that generate adequate human requi…
