Quasiparticle properties of nonequilibrium gluon plasma
2018
We apply classical gluodynamics to early stages of ultrarelativistic heavy-ion collisions. We start by giving a brief overview of QCD. Then we proceed to the space-time evolution of ultrarelativistic heavy-ion collisions in the color glass condensate framework and go through the basics of real-time gluodynamics on the lattice in the temporal gauge. We study the plasmon mass scale in three- and two-dimensional systems by comparing three different methods to measure the mass scale. The methods are a formula which can be derived from Hard Thermal Loop effective theory at leading order (HTL), the effective dispersion relation (DR) and measurement of the plasma oscillation frequency triggered by th…
Thermoluminescence response of sodalime glass irradiated with photon and electron beams in the 1-20 Gy range
2011
Abstract The thermoluminescence response of a watch commercial glass was studied after irradiation with photons and electrons, in the range 1–20 Gy, of interest in accidental dosimetry; a linear response was obtained with both beams. This result, together with the satisfactory time stability of the thermoluminescence signal, indicates this glass as a potential material for retrospective dosimetry applications.
Analyse du caractère dynamique des recommandations dans l'industrie cinématographique : le cas des franchises de films
2016
The release of motion picture sequels by studios led to the emergence of interaction effects between sequels over the time and in consequence altering models predicting the box office. If some scholars have examined these interaction effects, they were limited to the box office revenues. The paper proposes an extension of the interaction effects to third-party recommendations. The results – covering 123 sequels – demonstrate the dynamic and persistent nature of the recommendations.
QCD NLO with Powheg matching and top threshold matching in WHIZARD
2016
We present the status of the automation of NLO processes within the event generator WHIZARD. The program provides an automated FKS subtraction and phase space integration over the FKS regions, while the (QCD) NLO matrix element is accessed via the Binoth Les Houches Interface from an externally linked one-loop program. Massless and massive test cases and validation are shown for several e+e- processes. Furthermore, we discuss work in progress and future plans. The second part covers the matching of the NRQCD prediction with NLL threshold resummation to the NLO continuum top pair production at lepton colliders. Both the S-wave and P-wave production of the top pair are taken into account in t…
Photobleaching and Recovery Kinetics of a Palette of Carbon Nanodots Probed by In Situ Optical Spectroscopy
2022
Carbon dots (CDs) are a family of fluorescent nanoparticles displaying a wide range of interesting properties, which make them attractive for potential applications in different fields like bioimaging, photocatalysis, and many others. However, despite many years of dedicated studies, wide variations exist in the literature concerning the reported photostability of CDs, and even the photoluminescence mechanism is still unclear. Furthermore, an increasing number of recent studies have highlighted the photobleaching (PB) of CDs under intense UV or visible light beams. PB phenomena need to be fully addressed to optimize practical uses of CDs and can also provide information on the fundamental m…
Peri-Implant Behavior of Tissue Level Dental Implants with a Convergent Neck
2021
Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2
2021
[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…
A phenomenological research of democracy education in a Finnish primary-school
2023
This phenomenological research examines democracy education and the conditions contributing to young students’ democratic agency. The dataset includes interview and observation data from a school and educational decision-makers. The findings from the iterative analysis highlight the contradictions between democracy education as an ideal and opportunities for democratic agency. One significant contradiction was the expectation that young pupils should be competent democratic agents before being offered opportunities to act democratically. Young students deemed to possess the greatest competencies were offered opportunities to learn about democracy in action, whereas most students were expect…
Improving the operation of an emergency department by using a simulation model
2007
FL Toni Ruohonen on tutkinut väitöskirjassaan monia suomalaisia koskettavaa ongelmaa: terveydenhuollon päivystysjärjestelmän tehottomuutta. Tietokonesimulointia apuna käyttäen Ruohonen kehitti päivystyspoliklinikan uuden toimintamallin, jolla päivystykseen tulevan potilaan hoitoprosessia voidaan nopeuttaa jopa 40 %. – Terveydenhuollon yksiköt ovat hyvin monimutkaisia kokonaisuuksia, ja niillä on paljon satunnaisia piirteitä. Uusien teoreettisten ratkaisumallien kehittäminen ongelmiin on ollut melko helppoa, mutta niiden toimivuus on voitu osoittaa vasta käytännön kokeilun jälkeen, Ruohonen toteaa.Tutkimuksessa Ruohonen loi aluksi tietokoneella mallin oikeasta poliklinikasta sairaalan henkil…
Trouble in Paradise: a Case of a Technology Industry Supply Network
2009
The development of value networks is regarded as a necessity for achieving agility in global markets. Nowadays the focal companies often state that they are committing to more in-depth partnerships with selected suppliers, which are given more responsibility over both production and R&D. In this article we study the relationship of one focal company with its suppliers and identify the main concerns regarding governance and cooperation within the studied supply network in relation with the focal company’s strategy to enhance its innovative capabilities and ensure capacity in its supplier network. By analyzing the network relationships from three differing vantage points (the focal company, t…
