Naive and adapted utilization of the GPU for general purpose computing
(Master thesis, 2017)In this thesis we will see that adaptive utilization of the graphical processing unit (GPU) has much better performance than naive utilization, but it takes longer time to implement and requires more knowledge about ... 
Nano3Pseq: transcriptomewide analysis of gene expression and tail dynamics using endcapture nanopore cDNA sequencing
(Journal article; Peer reviewed, 2022)RNA polyadenylation plays a central role in RNA maturation, fate, and stability. In response to developmental cues, polyA tail lengths can vary, affecting the translation efficiency and stability of mRNAs. Here we develop ... 
Narrative Medical Visualization to Communicate Disease Data
(Journal article; Peer reviewed, 2022)This paper explores narrative techniques combined with medical visualizations to tell datadriven stories about diseases for a general audience. The field of medical illustration uses narrative visualization through ... 
Naturlige nettverk
(Master thesis, 2008)En innføring i naturlige nettverk. Vi forklarer og diskuterer begrepet naturlige nettverk og vurderer hvilke nettverk som bør kalles naturlige. Vi ser på forskjeller og likheter mellom tilfeldige, planlagte og naturlige ... 
Network coding in Bluetooth networks
(Master thesis, 20091001)This thesis discusses the possibility to apply network coding to a Bluetooth piconet. A protocol is proposed. This protocol is based on using deterministic linear network coding. The proposed alphabet size is binary, and ... 
Neural Substrates of Psychotic Depression: Findings From the Global ECTMRI Research Collaboration
(Journal article; Peer reviewed, 2021)Psychotic major depression (PMD) is hypothesized to be a distinct clinical entity from nonpsychotic major depression (NPMD). However, neurobiological evidence supporting this notion is scarce. The aim of this study is to ... 
Neutrophils induce paracrine telomere dysfunction and senescence in ROSdependent manner
(Journal article; Peer reviewed, 2021)Cellular senescence is characterized by an irreversible cell cycle arrest as well as a proinflammatory phenotype, thought to contribute to aging and agerelated diseases. Neutrophils have essential roles in inflammatory ... 
New cryptanalysis of LFSRbased stream ciphers and decoders for pary QCMDPC codes
(Doctoral thesis, 20220318)The security of modern cryptography is based on the hardness of solving certain problems. In this context, a problem is considered hard if there is no known polynomial time algorithm to solve it. Initially, the security ... 
A New Family of APN Quadrinomials
(Journal article; Peer reviewed, 2020)The binomial B(x) = x 3 +βx 36 (where β is primitive in F 2 2) over F 2 10 is the first known example of an Almost Perfect Nonlinear (APN) function that is not CCZequivalent to a power function, and has remained unclassified ... 
A New Generating Set Search Algorithm for Partially Separable Functions
(Chapter; Peer reviewed, 2010)A new derivativefree optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ... 
New KeyRecovery Attack on ReducedRound AES
(Journal article; Peer reviewed, 2022)A new fundamental 4round property of AES, called the zerodifference property, was introduced by Rønjom, Bardeh and Helleseth at Asiacrypt 2017. Our work characterizes it in a simple way by exploiting the notion of related ... 
New Lower Bounds on the Maximum Number of Minimal Connected Vertex Covers
(Master thesis, 20170620)Graphs are important mathematical structures that are used to model many reallife problems. They can, for instance, be used to model relations between objects in a network. An important field of study in graph theory is ... 
New Results on Minimal Triangulations
(Doctoral thesis, 20060425) 
New Results on the 1 Conjecture on CrossCorrelation of mSequences Based on Complete Permutation Polynomials
(Journal article; Peer reviewed, 2023)The crosscorrelation between two maximum length sequences (msequences) of the same period has been studied since the end of 1960s. One open conjecture by Helleseth states that the cross correlation between any two pary ... 
New Width Parameters of Graphs
(Doctoral thesis, 20120903)The main focus of this thesis is on using the divide and conquer technique to efficiently solve graph problems that are in general intractable. We work in the field of parameterized algorithms, using width parameters of ... 
Newsenhancer
(Master thesis, 20180823)This thesis describes a web browser plugin called NewsEnhancer, which has the goal to make it more efficient to read the news. The plugin receives data from a server application, which continuously aggregates meta information ... 
Node Multiway Cut and Subset Feedback Vertex Set on Graphs of Bounded MimWidth
(Journal article; Peer reviewed, 2022)The two weighted graph problems Node Multiway Cut (NMC) and Subset Feedback Vertex Set (SFVS) both ask for a vertex set of minimum total weight, that for NMC disconnects a given set of terminals, and for SFVS intersects ... 
NonConstructivity in Kan Simplicial Sets
(Journal article; Peer reviewed, 2015)We give an analysis of the nonconstructivity of the following basic result: if X and Y are simplicial sets and Y has the Kan extension property, then Y X also has the Kan extension property. By means of Kripke countermodels ... 
NonUniform kCenter and Greedy Clustering
(Journal article; Peer reviewed, 2022)In the NonUniform kCenter (NUkC) problem, a generalization of the famous kcenter clustering problem, we want to cover the given set of points in a metric space by finding a placement of balls with specified radii. In ...
