Measurement of transverse energy at midrapidity in Pb-Pb collisions at √sNN = 2.76 TeV
2016
We report the transverse energy (ET) measured with ALICE at midrapidity in Pb-Pb collisions at √sNN = 2.76 TeV as a function of centrality. The transverse energy was measured using identified single-particle tracks. The measurement was cross checked using the electromagnetic calorimeters and the transverse momentum distributions of identified particles previously reported by ALICE. The results are compared to theoretical models as well as to results from other experiments. The mean ET per unit pseudorapidity (η), dET/dη , in 0%–5% central collisions is 1737 ± 6(stat.) ± 97(sys.) GeV. We find a similar centrality dependence of the shape of dET/dη as a function of the number of participating …
Supporting employee engagement with internal communication for high reliability

Tämä pro gradu-työ tarkastelee kirjallisuuden ja empiirisen tutkimuksen avulla työntekijöiden sitoutumista organisaatioissa, joiden toiminnalle korkea luotettavuusvaatimus on edellytys. Työntekijöiden sitoutuminen ja sen merkitys organisaation menestykselle on noussut kiinnostuksenkohteeksi niin käytännössä kuin akateemisen tutkimuksen piirissä. Sisäinen viestintä on yksi väline jolla sitoutumista voi tukea organisaatiossa, ja sillä on myös merkitystä organisaation toimintavarmuudelle. Työ on laadullinen tutkimus, joka toteutettu pääosin abduktiivisella tutkimusmetodilla. Työssä on sekä teoreettinen että empiirinen osuus. Teoriaosuus käsittelee työntekijöiden sit…

One-loop corrections to light cone wave functions: the dipole picture DIS cross section
2018
We develop methods needed to perform loop calculations in light cone perturbation theory using a helicity basis, refining the method introduced in our earlier work. In particular this includes implementing a consistent way to contract the four-dimensional tensor structures from the helicity vectors with d-dimensional tensors arising from loop integrals, in a way that can be fully automatized. We demonstrate this explicitly by calculating the one-loop correction to the virtual photon to quark-antiquark dipole light cone wave function. This allows us to calculate the deep inelastic scattering cross section in the dipole formalism to next-to-leading order accuracy. Our results, obtained using …
Potential combined effects of maternal smoking and coffee intake on foetal death within the Danish National Birth Cohort
2018
Background: Several studies have linked coffee intake and smoking to foetal death, but a possible interaction between both exposures remains unknown.Methods: We studied, within the Danish National Birth Cohort, the potential interaction between smoking and coffee drinking while pregnant on the risk of foetal (early and late) death. The study included 90 086 pregnant women, with information about their smoking habit and coffee intake in early pregnancy, and several potential confounding factors. Interaction was studied by calculating both the hazard ratio (HR) in Cox's regression (linear and smoothed restricted cubic spline) and the interaction contrast ratio (ICR).Results: Women who neither…
Shell-model computed cross sections for charged-current scattering of astrophysical neutrinos off 40Ar
2018
Charged-current (anti)neutrino-$^{40}\mathrm{Ar}$ cross sections for astrophysical neutrinos have been calculated. The initial and final nuclear states were calculated using the nuclear shell model. The folded solar-neutrino scattering cross section was found to be $1.78(23)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}42}\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{2}$, which is higher than what the previous papers have reported. The contributions from the ${1}^{\ensuremath{-}}$ and ${2}^{\ensuremath{-}}$ multipoles were found to be significant at supernova-neutrino energies, confirming the random-phase approximation (RPA) result of a previous study. The effects of neutrino flavor conve…
A Decade of GRB Follow-Up by BOOTES in Spain (2003–2013)
2016
This article covers ten years of GRB follow-ups by the Spanish BOOTES stations: 71 follow-ups providing 23 detections. Follow-ups by BOOTES-1B from 2005 to 2008 were given in a previous article and are here reviewed and updated, and additional detection data points are included as the former article merely stated their existence. The all-sky cameras CASSANDRA have not yet detected any GRB optical afterglows, but limits are reported where available.
