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 ... -

On the Tractability of Optimization Problems on H-Graphs
(Journal article; Peer reviewed, 2020)For a graph H, a graph G is an H-graph if it is an intersection graph of connected subgraphs of some subdivision of H. H-graphs naturally generalize several important graph classes like interval graphs or circular-arc ... -
On the unique continuation of solutions to non-local non-linear dispersive equations
(Journal article; Peer reviewed, 2020)We prove unique continuation properties of solutions to a large class of nonlinear, non-local dispersive equations. The goal is to show that if u1,u2 are two suitable solutions of the equation defined in Rn×[0,T] such that ... -
On the Use of Dual Co-Polarized Radar Data to Derive a Sea Surface Doppler Model - Part 2: Simulation and Validation
(Journal article; Peer reviewed, 2023)The Doppler shift obtained from synthetic aperture radar (SAR) measurements comprises the combined contribution to the radial motion of the ocean surface induced by the sea state (wind waves and swell) and underlying surface ... -
On the utility of individual tendency output: Revealing interactions between parameterized processes during a marine cold air outbreak
(Journal article; Peer reviewed, 2021)Forecasts of marine cold air outbreaks critically rely on the interplay of multiple parameterization schemes to represent subgrid-scale processes, including shallow convection, turbulence, and microphysics. Even though ... -
On Two Fundamental Problems on APN Power Functions
(Journal article; Peer reviewed, 2022)The six infinite families of power APN functions are among the oldest known instances of APN functions, and it has been conjectured in 2000 that they exhaust all possible power APN functions. Another long-standing open ...
