Selection for biparental inheritance of mitochondria under hybridization and mitonuclear fitness interactions
(Journal article; Peer reviewed, 2021)Uniparental inheritance (UPI) of mitochondria predominates over biparental inheritance (BPI) in most eukaryotes. However, examples of BPI of mitochondria, or paternal leakage, are becoming increasingly prevalent. Most ... -
Semi-conditional variational auto-encoder for flow reconstruction and uncertainty quantification from limited observations
(Journal article; Peer reviewed, 2021)We present a new data-driven model to reconstruct nonlinear flow from spatially sparse observations. The proposed model is a version of a Conditional Variational Auto-Encoder (CVAE), which allows for probabilistic ... -
Semi-H-type groups and Semi-Damek-Ricci spaces

Semiparametric model selection for copulas
(Master thesis, 2013-06-03)This thesis will consider the performance of the cross-validation copula information criterion, xv-CIC, in the realm of finite samples. The theory leading to the xv-CIC will be outlined, and an analysis will be conducted ... -
Sequential Data Assimilation in High Dimensional Nonlinear Systems
(Doctoral thesis, 2011-10-21)Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ... -
Sequential Monte Carlo Methods for Bayesian Filtering

Sequential Monte Carlo Methods in Practice
(Master thesis, 2023-11-27)With the continuous increase in computational power, sequential Monte Carlo methods have emerged as an efficient technique for estimating unknown data in a world consisting of nonlinearity and non-Gaussianity. In this ... -
Sequential multilevel assimilation of inverted seismic data
(Journal article; Peer reviewed, 2023)We consider estimation of absolute permeability from inverted seismic data. Large amounts of simultaneous data, such as inverted seismic data, enhance the negative effects of Monte Carlo errors in ensemble-based Data ... -
Sequestration of Carbon in Saline Aquifers Mathematical and Numerical Analysis
(Doctoral thesis, 2004-04-30)The work in this thesis focuses equally on two main topics. The first of these subjects deals with development of criteria for monotonicity of con- trol volume methods. These methods are important and frequently used for ... -
Severi varieties on blow-ups of the symmetric square of an elliptic curve
(Journal article; Peer reviewed, 2023)We prove that certain Severi varieties of nodal curves of positive genus on general blow-ups of the twofold symmetric product of a general elliptic curve are nonempty and smooth of the expected dimension. This result, ... -
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 ... -
Ship wave patterns on floating ice sheets
(Journal article; Peer reviewed, 2022)This paper aims to explore the response of a floating icesheet to a load moving in a curved path. We investigate the effect of turning on the wave patterns and strain distribution, and explore scenarios where turning ... -
The Sibling Distribution for Multivariate Life Time Data
(Journal article; Peer reviewed, 2022)A flexible class of multivariate distributions for continuous lifetimes is proposed. The distribution is defined in terms of the age-at-death of m siblings. The expression for the joint density is derived using classical ... -
Sigma coordinate pressure gradient errors and the basin problem
(Master thesis, 2010-04-15)This work will focus on how the internal pressure gradient errors affect the numerical instability in idealised ocean basins. The nature of the errors will be investigated and discussed. First, in Chapter 1, the ocean model ... -
A simple wavelet-based test for serial correlation in panel data models
(Journal article; Peer reviewed, 2021)Hong and Kao (2004) proposed a class of general applicable wavelet-based tests for serial correlation of unknown form in the residuals from a panel regression model. The tests can be applied to both static and dynamic panel ... -
Simplified energy landscape for modularity using total variation
(Peer reviewed; Journal article, 2018)Networks capture pairwise interactions between entities and are frequently used in applications such as social networks, food networks, and protein interaction networks, to name a few. Communities, cohesive groups of nodes, ... -
Simplified models for numerical simulation of geological CO2 storage
(Doctoral thesis, 2017-02-03)Carbon capture and storage (CCS) is a proposed strategy to reduce global emissions of greenhouse-gases. The basic principle is to capture CO2 from power generation or other industrial activities and inject it into deep ... -
Simulating spatial and temporal varying CO2 signals from sources at the seafloor to help designing risk-based monitoring programs
(Peer reviewed; Journal article, 2016-01)Risk-based monitoring requires quantification of the probability of the design to detect the potentially adverse events. A component in designing the monitoring program will be to predict the varying signal caused by an ... -
Simulation of 3D hydrothermal circulation and application to faulted oceanic ridge systems
(Master thesis, 2022-06-01)Hydrothermal circulation in locations close to oceanic spreading ridges gives dissolved minerals from the crustal rock a chance to reach the seafloor. Temperature is increasing steadily with depth, heating water which ... -
