• #### 3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling ﻿

(Doctoral thesis, 2014-12-16)
Fault zones in siliciclastic rocks form distinct volumetric entities and typically exhibit great structural complexity. While it has been considered that the main impact of fault zones to fluid flow is to baffle or block ...
• #### 3D structure and formation of hydrothermal vent complexes at the paleocene-eocene transition, the Møre basin, MID-Norwegian margin ﻿

(Peer reviewed; Journal article, 2017-08)
The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ...
• #### $^{3}_{\Lambda}\mathrm H$ and $^{3}_{\bar{\Lambda}} \overline{\mathrm H}$ production in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV ﻿

(Peer reviewed; Journal article, 2016-03)
The production of the hypertriton nuclei $^{3}_{\Lambda}\mathrm H$ and $^{3}_{\bar{\Lambda}} \overline{\mathrm H}$ has been measured for the first time in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with the ...
• #### 3Λh and 3‾Λ‾h lifetime measurement in Pb–Pb collisions at √sNN = 5.02 TeV via two-body decay ﻿

(Peer reviewed; Journal article, 2019-10)
An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb–Pb collisions at sNN=5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been ...
• #### A 4 year prospective longitudinal study of progression of dental erosion associated to lifestyle in 13-14 year-old Swedish adolescents ﻿

(Peer reviewed; Journal article, 2016-04)
Objectives To evaluate the progression of dental erosion in 13–14 year-olds after 4 years, and its association with lifestyle and oral health. Methods 227 randomly selected 13–14 year-olds from a Public Dental Clinic, ...
• #### 4-Alkylated Silver–N-Heterocyclic Carbene (NHC) Complexes with Cytotoxic Effects in Leukemia Cells ﻿

(Peer reviewed; Journal article, 2015-08-06)
Computational chemistry has shown that backbone-alkylated imidazoles ought to be efficient ligands for transition metal catalysts with improved carbene-to-metal donation. In this work, such alkylated imidazoles were ...
• #### A 43k Kernel for Planar Dominating Set using Computer-Aided Reduction Rule Discovery ﻿

(Master thesis, 2016-02-15)
In this thesis we explore the technique of Region Decomposition for finding kernels for Planar Dominating Set. We redefine some concepts used in earlier work, fixing some ambiguities on the way. From those concepts we end ...
• #### 450K epigenome-wide scan identifies differential DNA methylation in newborns related to maternal smoking during pregnancy ﻿

(Peer reviewed; Journal article, 2012-10)
Background: Epigenetic modifications, such as DNA methylation, due to in utero exposures may play a critical role in early programming for childhood and adult illness. Maternal smoking is a major risk factor for multiple ...
