Can Local Stress Enhancement Induce Stability in Fracture Processes? Part II: The Shielding Effect
(Journal article; Peer reviewed, 2019)We use the local load sharing fiber bundle model to demonstrate a shielding effect where strong fibers protect weaker ones. This effect exists due to the local stress enhancement around broken fibers in the local load ... -
Chiral Phonon Transport Induced by Topological Magnons
(Peer reviewed; Journal article, 2019)The plethora of recent discoveries in the field of topological electronic insulators has inspired a search for boson systems with similar properties. There are predictions that ferromagnets on a two-dimensional honeycomb ... -
Crack localization and the interplay between stress enhancement and thermal noise
(Peer reviewed; Journal article, 2021)We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The thermal noise is introduced by defining a ... -
Fluid Meniscus Algorithms for Dynamic Pore-Network Modeling of Immiscible Two-Phase Flow in Porous Media
(Peer reviewed; Journal article, 2021)We present in detail a set of algorithms for a dynamic pore-network model of immiscible two-phase flow in porous media to carry out fluid displacements in pores. The algorithms are universal for regular and irregular pore ... -
Mesospheric nitric oxide model from SCIAMACHY data
(Journal article; Peer reviewed, 2019)We present an empirical model for nitric oxide (NO) in the mesosphere (60–90 km) derived from SCIAMACHY limb scan data. Our model relates the daily (longitudinally) averaged NO number densities from SCIAMACHY as a function ... -
MRI-based automatic segmentation of rectal cancer using 2D U-Net on two independent cohorts
(Peer reviewed; Journal article, 2021)Background Tumor delineation is time- and labor-intensive and prone to inter- and intraobserver variations. Magnetic resonance imaging (MRI) provides good soft tissue contrast, and functional MRI captures tissue properties ... -
Spin-sensitive long-range proximity effect in ferromagnet/spin-triplet-superconductor bilayers
(Journal article; Peer reviewed, 2011)The discovery of noncentrosymmetric superconductors, such as CePt3Si, and chiral superconductors, such as Sr2RuO4, calls for experimental methods to identify the presence of spin-triplet pairing. We here demonstrate a ... -
Transition from viscous fingers to foam during drainage in heterogeneous porous media
(Peer reviewed; Journal article, 2023)We investigate the behavior of drainage displacements in heterogeneous porous media finding a transition from viscous fingering to foam-like region. A pore network model incorporating the formation of blobs is adopted to ...
