A (2 + ε)Factor Approximation Algorithm for Split Vertex Deletion
(Journal article; Peer reviewed, 2020)In the Split Vertex Deletion (SVD) problem, the input is an nvertex undirected graph G and a weight function w: V(G) → ℕ, and the objective is to find a minimum weight subset S of vertices such that GS is a split graph ... 
Accuracy and efficiency of germline variant calling pipelines for human genome data
(Journal article; Peer reviewed, 2020)Advances in nextgeneration sequencing technology have enabled whole genome sequencing (WGS) to be widely used for identification of causal variants in a spectrum of geneticrelated disorders, and provided new insight into ... 
Accurate analysis of genuine CRISPR editing events with ampliCan
(Peer reviewed; Journal article, 2019)We present ampliCan, an analysis tool for genome editing that unites highly precise quantification and visualization of genuine genome editing events. ampliCan features nucleaseoptimized alignments, filtering of experimental ... 
Additive Schwarz preconditioner for the finite volume element discretization of symmetric elliptic problems
(Peer reviewed; Journal article, 20150925)A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a class of finite volume element discretization of the symmetric elliptic problem in two dimensions, with large ... 
An Algorithmic MetaTheorem for Graph Modification to Planarity and FOL
(Journal article; Peer reviewed, 2020)In general, a graph modification problem is defined by a graph modification operation ⊠ and a target graph property 𝒫. Typically, the modification operation ⊠ may be vertex removal, edge removal, edge contraction, or edge ... 
Algorithms for the Rainbow Vertex Coloring Problem on Graph Classes
(Journal article; Peer reviewed, 2020)Given a vertexcolored graph, we say a path is a rainbow vertex path if all its internal vertices have distinct colors. The graph is rainbow vertexconnected if there is a rainbow vertex path between every pair of its ... 
Application of quantitative transcriptomics in evaluating the ex vivo effects of per and polyfluoroalkyl substances on Atlantic cod (Gadus morhua) ovarian physiology
(Journal article; Peer reviewed, 2021)Because of their global consumption and persistence, per and polyfluoroalkyl substances (PFASs), are ubiquitously distributed in the environment, as well as in wildlife and humans. In the present study, we have employed ... 
An Approach to Flexible Multilevel Modelling
(Peer reviewed; Journal article, 20180712)Multilevel modelling approaches tackle issues related to lack of flexibility and mixed levels of abstraction by providing features like deep modelling and linguistic extension. However, the lack of a clear consensus on ... 
Approximating Acyclicity Parameters of Sparse Hypergraphs
(Conference object; Peer reviewed; Journal article, 2009)The notions of hypertree width and generalized hypertree width were introduced by Gottlob, Leone, and Scarcello (PODS'99, PODS'01) in order to extend the concept of hypergraph acyclicity. These notions were further generalized ... 
Approximating cube roots of integers, after Heron’s Metrica III.20
(Peer reviewed; Journal article, 2013) 
Approximation algorithms in combinatorial scientific computing
(Journal article; Peer reviewed, 2019)We survey recent work on approximation algorithms for computing degreeconstrained subgraphs in graphs and their applications in combinatorial scientific computing. The problems we consider include maximization versions of ... 
Approximation in (poly) logarithmic space
(Journal article; Peer reviewed, 2020)We develop new approximation algorithms for classical graph and set problems in the RAM model under space constraints. As one of our main results, we devise an algorithm for d–Hitting Set that runs in time nO(d2+(d/ε)), ... 
Associations Between Natural Physiological and Supraphysiological Estradiol Levels and Stress Perception
(Peer reviewed; Journal article, 20190611)Stress is a risk factor for impaired general, mental, and reproductive health. The role of physiological and supraphysiological estradiol concentrations in stress perception and stress processing is less well understood. ... 
The Atlantic salmon genome provides insights into rediploidization
(Peer reviewed; Journal article, 201605)The wholegenome duplication 80 million years ago of the common ancestor of salmonids (salmonidspecific fourth vertebrate wholegenome duplication, Ss4R) provides unique opportunities to learn about the evolutionary fate ... 
Attacks on IntegerRLWE
(Journal article; Peer reviewed, 2020)In 2019, Gu Chunsheng introduced IntegerRLWE, a variant of RLWE devoid of some of its efficiency flaws. Most notably, he proposes a setting where n can be an arbitrary positive integer, contrarily to the typical construction ... 
Automatic interpretation of otoliths using deep learning
(Peer reviewed; Journal article, 20181217)The age structure of a fish population has important implications for recruitment processes and population fluctuations, and is a key input to fisheriesassessment models. The current method of determining age structure ... 
Automatic interpretation of salmon scales using deep learning
(Journal article; Peer reviewed, 2021)For several fish species, age and other important biological information is manually inferred from visual scrutinization of scales, and reliable automatic methods are not widely available. Here, we apply Convolutional ... 
AxiomBased Transformations: Optimisation and Testing
(Peer reviewed; Journal article, 20091010)Programmers typically have knowledge about properties of their programs that aren't explicitly expressed in the code properties that may be very useful for, e.g., compiler optimisation and automated testing. Although ... 
Axis patterning by BMPs: cnidarian network reveals evolutionary constraints
(Peer reviewed; Journal article, 201503)BMP signaling plays a crucial role in the establishment of the dorsoventral body axis in bilaterally symmetric animals. However, the topologies of the bone morphogenetic protein (BMP) signaling networks vary drastically ... 
Bchromatic number: Beyond NPhardness
(Conference object; Peer reviewed; Journal article, 2015)The bchromatic number of a graph G, chi_b(G), is the largest integer k such that G has a kvertex coloring with the property that each color class has a vertex which is adjacent to at least one vertex in each of the other ...
