Non-Constructivity in Kan Simplicial Sets
(Journal article; Peer reviewed, 2015)We give an analysis of the non-constructivity 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 ... -
Non-Equilibrium Fractionation Factors for D/H and 18O/16O During Oceanic Evaporation in the North-West Atlantic Region
(Journal article; Peer reviewed, 2022)Ocean isotopic evaporation models, such as the Craig-Gordon model, rely on the description of nonequilibrium fractionation factors that are, in general, poorly constrained. To date, only a few gradient-diffusion type ... -
Non-invasive studies of multiphase flow in process equipment. Positron emission particle tracking technique
(Peer reviewed; Journal article, 2017)Positron emission particle tracking (PEPT) is a novel experimental technique for non-invasive inspection of industrial fluid/particle flows. The method is based on the dynamic positioning of a positron-emitting, flowing ... -
Non-linear flow modes of identified particles in Pb-Pb collisions at √sNN = 5.02 TeV
(Journal article; Peer reviewed, 2020)The pT-differential non-linear flow modes, v4,22, v5,32, v6,33 and v6,222 for π±, K±, K0S , p + p¯¯¯, Λ + Λ¯¯¯¯ and ϕ-meson have been measured for the first time at sNN−−−√ = 5.02 TeV in Pb-Pb collisions with the ALICE ... -
Non-linear flow modes of identified particles in Pb–Pb collisions at √sNN=5.02TeV with the ALICE detector
(Peer reviewed; Journal article, 2019)The non-linear flow modes, v4,22, v5,32 and v6,33 as a function of transverse momentum (pT) have been measured for the first time in Pb–Pb collisions at √sNN = 5.02 TeV for identified particles, i.e. charged pions, kaons ... -
Non-linear retreat of Jakobshavn Isbræ since the Little Ice Age controlled by geometry
(Journal article, 2017-09)Rapid acceleration and retreat of Greenland's marine-terminating glaciers during the last two decades have initiated questions on the trigger and processes governing observed changes. Destabilization of these glaciers ... -
Non-Polar Natural Products from Bromelia laciniosa, Neoglaziovia variegata and Encholirium spectabile (Bromeliaceae)
(Peer reviewed; Journal article, 2017-09-06)Extensive regional droughts are already a major problem on all inhabited continents and severe regional droughts are expected to become an increasing and extended problem in the future. Consequently, extended use of available ... -
Non-Slit Solutions to the Loewner Equation
(Master thesis, 2010-04-30)We study conditions on the driving term of the Loewner equation which guarantee that the equation generates slits. We construct a new family of examples of non-slit solutions which generalize Kufarev's example, in which ... -
Non-standard shocks in the Buckley-Leverett equation
(Peer reviewed; Journal article, 2015-08)It is shown how delta shock waves which consist of Dirac delta distributions and classical shocks can be used to construct non-monotone solutions of the Buckley–Leverett equation. These solutions are interpreted using a ... -
Non-strange and strange D-meson and charm-baryon production in heavy-ion collisions measured with ALICE at the LHC
(Peer reviewed; Journal article, 2019)We present recent results on strange and non-strange D-meson production measured with ALICE in Pb–Pb collisions at the LHC. In addition, the measurements of the Λ+ c -baryon production and of the Λ+ c /D0 ratio in pp, p–Pb, ... -
Non-Uniform k-Center and Greedy Clustering
(Journal article; Peer reviewed, 2022)In the Non-Uniform k-Center (NUkC) problem, a generalization of the famous k-center 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 ... -
Non-visual photoreceptive systems in early development of Atlantic halibut (Hippoglossus hippoglossus)
(Doctoral thesis, 2014-03-28)Non-visual photoreception is thought to be involved in a range of behavioural and physiological processes in teleost fishes, such as synchronisation of circadian and circannual rhythms, but also regulation of skin pigmentation, ... -
Nonemptiness of severi varieties on enriques surfaces
(Journal article; Peer reviewed, 2023)Let (S,L) be a general polarised Enriques surface, with L not numerically 2-divisible. We prove the existence of regular components of all Severi varieties of irreducible nodal curves in the linear system |L| , that is, ... -
Nonholonomic geometry on finite and infinite dimensional Lie groups and rolling manifolds
(Doctoral thesis, 2012-03-30)Part I: We start by giving some background on the topics discussed in this thesis. The main topic of the thesis is nonholonomic geometry. In Chapter 1 we give an introduction of nonholonomic geometry in the context of ... -
Nonhydrostatic pressure in ocean models with focus on wind driven internal waves

Nonlinear cross-spectrum analysis via the local Gaussian correlation
(Journal article, 2017)Spectrum analysis can detect frequency related structures in a time series \(\{Y_t\}_{t\in\mathbb{Z}}\), but may in general be an inadequate tool if asymmetries or other nonlinear phenomena are present. This limitation is ... -
A Nonlinear Differential Equation Solver With Potential Application to Pelton Turbines
(Doctoral thesis, 2016-05-02)The focus in this thesis is the development and implementation of a new method for solving nonlinear differential equations on a grid. The method’s novelty lies in the way it represents continuously distributed variables ... -
Nonlinear echoes from encapsulated antibubbles
(Peer reviewed; Journal article, 2015-09-19)An antibubble consists of a liquid droplet, surrounded by a gas, often with an encapsulating shell. Antibubbles of microscopic sizes suspended in fluids are acoustically active in the ultrasonic range. Antibubbles have ... -
