(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)We measure [C iii] 1907, C iii] 1909 Å emission lines in 11 gravitationally lensed star-forming galaxies at z ~ 1.6–3, finding much lower equivalent widths than previously reported for fainter lensed galaxies. While it is ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)We study ordinary differential equations (ODEs) with vector fields given by general Schwartz distributions, and we show that if we perturb such an equation by adding an “infinitely regularizing” path, then it has a unique ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)We introduce algebraic dynamical systems, which consist of an action of a right LCM semigroup by injective endomorphisms of a group. To each algebraic dynamical system we associate a C*-algebra and describe it as a semigroup ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract We study C*-algebras generated by left regular representations of right LCM one-relator monoids and Artin–Tits monoids of finite type. We obtain structural results concerning nuclearity, ideal structure and pure ...

(Doctoral thesis / Doktoravhandling, 2023)Mathematical objects often possess some sort of 'symmetry'. For instance, the circle has rotational symmetry; It 'looks the same' even if we rotate it around its center by some angle. Formally this type of symmetry is an ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We study C*-irreducibility of inclusions of reduced twisted group C*-algebras and of reduced group C*-algebras. We characterize C*-irreducibility in the case of an inclusion arising from a normal subgroup, and exhibit many ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We study non-ascending HNN extensions acting on their Bass– Serre tree and characterize C*-simplicity and the unique trace property by means of the kernel and quasi-kernels of the HNN extension in question. We also present ...

(Master thesis / Masteroppgave, 2015)8-Substituted purines have been extensively studied as for example anticancer or antiviral drugs. C-C Bond formation at the purine 8-position has been most commonly done via 8-halopurines, e.g. Pd-catalyzed coupling ...

(Doctoral thesis / Doktoravhandling, 2021)Copper salts are often used to activate the C-H bond of alkynes and to catalyze the cycloaddition of alkynes to azides (CuAAC reaction). While cheap and easily accessible, the copper salts generate many different active ...

(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)In this paper we construct a new type of noise of fractional nature that has a strong regularizing effect on differential equations. We consider an equation with this noise with a highly irregular coefficient. We employ a ...
-
(Master thesis / Masteroppgave, 2015)This thesis is devoted to the simultaneous estimation of the means of p> 1 independent Poisson distributions. A novel loss function that penalizes bad estimates of each of the means and the sum of the means is introduced. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Strict control of tissue-specific gene expression plays a pivotal role during lineage commit- ment. The transcription factor c-Myb has an essential role in adult haematopoiesis and func- tions as an oncogene when rearranged ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The transcription factor c-Myb is involved in early differentiation and proliferation of haematopoietic cells, where it operates as a regulator of self-renewal and multi-lineage differentiation. Deregulated c-Myb plays ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Prostate cancer (PCa) is the most common non-cutaneous cancer in men. The androgen receptor (AR), a ligand-activated transcription factor, constitutes the main drug target for advanced cases of the disease. However, a ...
