A New Concept to Measure the Ambipolar Electric Field Driving Ionospheric Outflow
(Journal article; Peer reviewed, 2021)Over the last few decades, the role of ionospheric outflow for the loss of atmospheric constituents, as a plasma supplier to the magnetosphere and hence for the evolution of the Earth’s atmosphere has been recognized. A ... -
New Conceptual Toxicokinetic Model to Assess Synergistic Mixture Effects between the Aromatic Hydrocarbon β-Naphthoflavone and the Azole Nocodazole on the CYP1A Biomarker in a Fish Cell Line
(Journal article; Peer reviewed, 2020)Toxicokinetic interactions with catabolic cytochrome P450 (CYP) enzymes can inhibit chemical elimination pathways and cause synergistic mixture effects. We have created a mathematical bottom-up model for a synergistic ... -
New cryptanalysis of LFSR-based stream ciphers and decoders for p-ary QC-MDPC codes
(Doctoral thesis, 2022-03-18)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 ... -
New ecosystems in the deep subsurface follow the flow of water driven by geological activity
(Peer reviewed; Journal article, 2019-03-01)Eukarya have been discovered in the deep subsurface at several locations in South Africa, but how organisms reach the subsurface remains unknown. We studied river-subsurface fissure water systems and identified Eukarya ... -
New Evidence About Aortic Valve Stenosis and Cardiovascular Hemodynamics
(Journal article; Peer reviewed, 2022)Aortic stenosis (AS) is the most common degenerative valvular disease in western word. In patients with severe AS, small changes in aortic valve area can lead to large changes in hemodynamics. The correct understanding of ... -
New evidence of bone tool use by Early Pleistocene hominins from Cooper’s D, Bloubank Valley, South Africa
(Journal article; Peer reviewed, 2021)Bone tool-use by Early Pleistocene hominins is at the centre of debates in human evolution. It is especially the case in South Africa, where 102 bone tools have been described from four Early Stone Age archaeological sites, ... -
New examples of curves with a one-dimensional family of pencils of minimal degree
(Peer reviewed; Journal article, 2011-07-14)We give a geometric construction of sub-linear systems on a K3 surface consisting of smooth curves C with infinitely many g1 gon(C)’s. -
New experimental techniques to study the adhesion to various solid surfaces of hydrate-relevant droplets and particles
(Master thesis, 2010-10-01)Hydrate plugging is a substantial problem in the oil and gas industry, both economically, environmentally and safety wise. Plugging may occur as a result of agglomeration of hydrate particles, deposition of hydrates on the ... -
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 CCZ-equivalent to a power function, and has remained unclassified ... -
New flood frequency estimates for the largest river in Norway based on the combination of short and long time series
(Journal article; Peer reviewed, 2020)The Glomma River is the largest in Norway, with a catchment area of 154 450 km2. People living near the shores of this river are frequently exposed to destructive floods that impair local cities and communities. Unfortunately, ... -
A new framework for assessing subject-specific whole brain circulation and perfusion using MRI-based measurements and a multi-scale continuous flow model
(Peer reviewed; Journal article, 2019-06-25)A large variety of severe medical conditions involve alterations in microvascular circulation. Hence, measurements or simulation of circulation and perfusion has considerable clinical value and can be used for diagnostics, ... -
A New French Revolution? An integrative approach in the analysis of the Romanian transition
(Master thesis, 2001)This thesis has focued on the Romanian transition. The critical period concerned was from March 1989, with apparent signs of liberalisation, to the 1990 elections. Romania differed from the East and Central European ... -
New Frontiers in Creativity, Learning, and Technology Research
(Journal article; Peer reviewed, 2021)This article offers a brief introduction to the special issue ‘New frontiers in creativity, learning, and technology research’ by situating the topic and explaining the events and previous publications that led to this new ... -
A New Generating Set Search Algorithm for Partially Separable Functions
(Chapter; Peer reviewed, 2010)A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ... -
A new genus of Podonominae (Diptera: Chironomidae) in Late Eocene Rovno amber from Ukraine
(Peer reviewed; Journal article, 2014-05-08)The genus Palaeoboreochlus Baranov et Andersen, n. gen. is erected based on P. inornatus Baranov et Andersen, n. sp. described from a male found in Late Eocene Rovno amber. The new genus groups with Boreochlus Edwards in ... -
A new global ice sheet reconstruction for the past 80 000 years
(Journal article; Peer reviewed, 2021)The evolution of past global ice sheets is highly uncertain. One example is the missing ice problem during the Last Glacial Maximum (LGM, 26 000-19 000 years before present) – an apparent 8-28 m discrepancy between far-field ... -
A new global interior ocean mapped climatology: the 1° × 1° GLODAP version 2
(Peer reviewed; Journal article, 2016-08-15)We present a mapped climatology (GLODAPv2.2016b) of ocean biogeochemical variables based on the new GLODAP version 2 data product (Olsen et al., 2016; Key et al., 2015), which covers all ocean basins over the years 1972 ... -
