On the Impact of a Streaming Oxygen Population on Collisionless Magnetic Reconnection
(Journal article; Peer reviewed, 2020)Using 2.5-D Particle-In-Cell (PIC) simulations, we investigate how magnetotail reconnection is affected by a cold, streaming, oxygen plasma population, attributed to an ionospheric source, in the inflow region. As the ... -
On the importance of parenting in externalizing disorders: an evaluation of indirect genetic effects in families
(Journal article; Peer reviewed, 2022)Background: Theoretical models of the development of childhood externalizing disorders emphasize the role of parents. Empirical studies have not been able to identify specific aspects of parental behaviors explaining a ... -
On the IND-CCA1 Security of FHE Schemes
(Journal article; Peer reviewed, 2022)Fully homomorphic encryption (FHE) is a powerful tool in cryptography that allows one to perform arbitrary computations on encrypted material without having to decrypt it first. There are numerous FHE schemes, all of which ... -
On the Influence of Sea Surface Temperature distributions on the Development of Extratropical Cyclones
(Journal article; Peer reviewed, 2021)The sea surface temperature (SST) distribution can modulate the development of extratropical cyclones through sensible and latent heat fluxes. However, the direct and indirect effects of these surface fluxes, and thus the ... -
On the Mainstream/Alternative Continuum: Mainstream Media Reactions to Right-Wing Alternative News Media
(Journal article; Peer reviewed, 2021)Using the mainstream media as a starting point, this article argues that the ongoing changes in the mainstream/alternative continuum are not just dependent on how right-wing alternative news media relate to certain ... -
On the maximum number of edges in planar graphs of bounded degree and matching number
(Journal article; Peer reviewed, 2023)We determine the maximum number of edges that a planar graph can have as a function of its maximum degree and matching number. -
On the Modelling of Immiscible Viscous Fingering in Two Phase Flow in Porous Media
(Journal article; Peer reviewed, 2020)Viscous fingering in porous media is an instability which occurs when a low-viscosity injected fluid displaces a much more viscous resident fluid, under miscible or immiscible conditions. Immiscible viscous fingering is ... -
On the Origins of Open Ocean Oxygen Minimum Zones
(Journal article; Peer reviewed, 2023)Recent work suggests that Oxygen Minimum Zones (OMZs) are sustained by the supply of oxygen-poor waters rather than the export of organic matter from the local surface layer and its subsequent remineralization inside OMZs. ... -
On the parameterized complexity of deletion to H-free strong components
(Journal article; Peer reviewed, 2020)Directed Feedback Vertex Set (DFVS) is a fundamental computational problem that has received extensive attention in parameterized complexity. In this paper, we initiate the study of a wide generalization, the H-SCC Deletion ... -
On the Parameterized Complexity of the Expected Coverage Problem
(Journal article; Peer reviewed, 2022)The MAXIMUM COVERING LOCATION PROBLEM (MCLP) is a well-studied problem in the field of operations research. Given a network with positive or negative demands on the nodes, a positive integer k, the MCLP seeks to find k ... -
On the path towards universal coverage of hepatitis C treatment among people receiving opioid agonist therapy (OAT) in Norway: A prospective cohort study from 2013 to 2017
(Journal article; Peer reviewed, 2020)Objectives We aimed to calculate cumulative hepatitis C virus (HCV) treatment coverage among individuals enrolled in opioid agonist therapy (OAT) in Norway between 2013 and 2017 and to document the treatment transition to ... -
On the political feasibility of climate change mitigation pathways: Is it too late to keep warming below 1.5° C?
(Journal article; Peer reviewed, 2020)Keeping global warming below 1.5°C is technically possible but is it politically feasible? Understanding political feasibility requires answering three questions: (a) “Feasibility of what?,” (b) “Feasibility when and ... -
On the potential for megathrust earthquakes and tsunamis off the southern coast of West Java and southeast Sumatra, Indonesia
(Journal article; Peer reviewed, 2022)High seismicity rates in and around West Java and Sumatra occur as a result of the Indo-Australian plate converging with and subducting beneath the Sunda plate. Large megathrust events associated with this process likely ... -
On the Potential for Optical Detection of Microplastics in the Ocean

On the Presence and Thermalization of Cold Ions in the Exhaust of Antiparallel Symmetric Reconnection
(Journal article; Peer reviewed, 2021)Using fully kinetic 2.5 dimensional particle-in-cell simulations of anti-parallel symmetric magnetic reconnection, we investigate how initially cold ions are captured by the reconnection process, and how they evolve and ... -
On the Production of Ionospheric Irregularities Via Kelvin-Helmholtz Instability Associated with Cusp Flow Channels
(Journal article; Peer reviewed, 2020)We present a multi‐instrument multiscale study of a channel of enhanced, inhomogeneous flow in the cusp ionosphere occurring on November 30, 2014. We provide evidence that strong Global Navigation Satellite System (GNSS) ... -
On the rate of convergence of alternating minimization for non-smooth non-strongly convex optimization in Banach spaces
(Journal article; Peer reviewed, 2022)In this paper, the convergence of the fundamental alternating minimization is established for non-smooth non-strongly convex optimization problems in Banach spaces, and novel rates of convergence are provided. As objective ... -
On the Satisfiability of Smooth Grid CSPs
(Journal article; Peer reviewed, 2022)Many important NP-hard problems, arising in a wide variety of contexts, can be reduced straightforwardly to the satisfiability problem for CSPs whose underlying graph is a grid. In this work, we push forward the study of ... -
On the Sombor characteristic polynomial and Sombor energy of a graph
(Journal article; Peer reviewed, 2022)Let G be a simple graph with vertex set V(G)={v1,v2,…,vn}. The Sombor matrix of G, denoted by ASO(G), is defined as the n×n matrix whose (i, j)-entry is d2i+d2j−−−−−−√ if vi and vj are adjacent and 0 for another cases. Let ... -
