• #### Brill–Noether general K3 surfaces with the maximal number of elliptic pencils of minimal degree ﻿

(Journal article; Peer reviewed, 2020)
We explicitly construct Brill–Noether general K3 surfaces of genus 4, 6 and 8 having the maximal number of elliptic pencils of degrees 3, 4 and 5, respectively, and study their moduli spaces and moduli maps to the moduli ...
• #### Radial processes for sub-Riemannian Brownian motions and applications ﻿

(Journal article; Peer reviewed, 2020)
We study the radial part of sub-Riemannian Brownian motion in the context of totally geodesic foliations. Itô’s formula is proved for the radial processes associated to Riemannian distances approximating the Riemannian ...
• #### Numerical modeling of wing crack propagation accounting for fracture contact mechanics ﻿

(Journal article; Peer reviewed, 2020)
As a consequence of shearing, wing cracks can emerge from pre-existing fractures. The process involves the interaction of sliding of the existing fracture surfaces and the tensile material failure that creates wing cracks. ...
• #### The dynamics of trait variance in multi-species communities: Multi-species trait variance dynamics ﻿

(Journal article; Peer reviewed, 2020)
In this paper, we establish the explicit connection between deterministic trait-based population-level models (in the form of partial differential equations) and species-level models (in the form of ordinary differential ...
• #### Robust solvers for fully coupled transport and flow in saturated/unsaturated porous media ﻿

(Doctoral thesis, 2021-03-29)
Numerical simulations and laboratory studies are our main tools to comprehend better processes happening in the subsurface. The phenomena are modeled thanks to systems of partial differential equations (PDEs), which are ...
• #### Iterative schemes for surfactant transport in porous media ﻿

(Journal article; Peer reviewed, 2020)
In this work, we consider the transport of a surfactant in variably saturated porous media. The water flow is modelled by the Richards equations and it is fully coupled with the transport equation for the surfactant. Three ...
• #### Sparse-Data Based 3D Surface Reconstruction for Cartoon and Map ﻿

(Conference object, 2018)
A model combining the first-order and the second-order variational regularizations for the purpose of 3D surface reconstruction based on 2D sparse data is proposed. The model includes a hybrid fidelity constraint which ...
• #### Associations between the number of children, age at childbirths and prevalence of chronic low back pain: the Nord-Trøndelag Health Study ﻿

(Journal article; Peer reviewed, 2020)
Background Associations between childbirths and subsequent risk of low back pain (LBP) have not been clarified. Changes in sex hormone levels or lumbar posture during pregnancy may have an impact on LBP later in life. The ...
• #### Microfluidic study of effects of flow velocity and nutrient concentration on biofilm accumulation and adhesive strength in the flowing and no-flowing microchannels ﻿

(Journal article; Peer reviewed, 2019)
Biofilm accumulation in porous media can cause pore plugging and change many of the physical properties of porous media. Engineering bioplugging may have significant applications for many industrial processes, while improved ...
• #### TV-Stokes And Its Variants For Image Processing ﻿

(Doctoral thesis, 2021-03-30)
The total variational minimization with a Stokes constraint, also known as the TV-Stokes model, has been considered as one of the most successful models in image processing, especially in image restoration and sparse-data-based ...
• #### A singularity removal method for coupled 1D–3D flow models ﻿

(Journal article; Peer reviewed, 2019)
In reservoir simulations, the radius of a well is inevitably going to be small compared to the horizontal length scale of the reservoir. For this reason, wells are typically modelled as lower-dimensional sources. In this ...
• #### Modelling and simulation of thermo-hydro-mechanical processes in fractured porous media ﻿

(Doctoral thesis, 2021-02-26)
Understanding and predicting processes in fractured porous media is of wide interest, with applications such as geothermal energy extraction, water management and storage of CO$_2$ and energy. Characterisation and monitoring ...
• #### The Effect of Environmental Stressors on Tinnitus: A Prospective Longitudinal Study on the Impact of the COVID-19 Pandemic ﻿

(Journal article; Peer reviewed, 2020-08)
Tinnitus, the perception of sound in the absence of a corresponding sound, and the distress caused by it, is rarely a static phenomenon. It rather fluctuates over time depending on endogenous and exogenous factors. The ...
• #### Impact of drone route geometry on information collection in wireless sensor networks ﻿

(Journal article; Peer reviewed, 2020-09)
The recent technological evolution of drones along with the constantly growing maturity of its commercialization, has led to the emergence of novel drone-based applications within the field of wireless sensor networks for ...
• #### Sexual dimorphism in the familial aggregation of tinnitus ﻿

(Journal article; Peer reviewed, 2020-11)
Twin and adoption studies point towards a genetic contribution to tinnitus; however, how the genetic risk applies to different forms of tinnitus is poorly understood. Here, we perform a familial aggregation study and ...
• #### Association between Hyperacusis and Tinnitus ﻿

(Journal article; Peer reviewed, 2020-07)
Many individuals with tinnitus report experiencing hyperacusis (enhanced sensitivity to sounds). However, estimates of the association between hyperacusis and tinnitus is lacking. Here, we investigate this relationship in ...
• #### Relationship between headaches and tinnitus in a Swedish study ﻿

(Journal article; Peer reviewed, 2020-05)
The heterogeneity of tinnitus is likely accounting for the lack of effective treatment approaches. Headaches have been related to tinnitus, yet little is known on how headaches impact tinnitus. We use cross-sectional data ...
• #### Iterative solvers for Biot model under small and large deformation ﻿

(Journal article; Peer reviewed, 2020-07-18)
We consider L-scheme and Newton-based solvers for Biot model under large deformation. The mechanical deformation follows the Saint Venant-Kirchoff constitutive law. Furthermore, the fluid compressibility is assumed to be ...
