Inclination-dependent grain boundary (GB) energy and shear-coupled motion are studied for [001] and [111] tilt GBs in face-centered cubic materials using three-dimensional (3D) phase field crystal (PFC) simulations. A large dataset spanning misorientation and inclination space is systematically generated to evaluate trends in GB energy and shear-coupling. GB energy variations broadly follow ideal
Spiral galaxies, like the Milky Way, transform at some point in time into a rotationally supported system. Using an extant dataset consisting of 319,835 subgiants from LAMOST with precise ages from the literature, we determine, for the first time, the age when the Milky Way disk spins up, i.e., when the mean circular velocity changes from halo-like to disk-like. We find in concordance previous stu
This work investigates a new regularization method for conditional variational autoencoder networks in unsupervised anomaly detection. The proposed regularization takes advantage of the network’s ability to embed images into a lower-dimensional latent space according to clusters of known classes. Previous literature has predominantly implemented cluster locations as learnable parameters of the mod
Notation frameworks have long existed to help structure propositional logic, and to map out philosophical arguments. Similar frameworks exist for outlining long texts and scaffolding manuscript drafting. These frameworks are helpful in structuring texts and developing drafts, yet can still leave the draft with hidden incoherence. To address this gap I propose ArgMap, a notation system based on cat
Recovery of plastically deformed metals involves several stages of substructure evolution during which dislocation entanglements and networks become increasingly organized, thereby lowering the stored energy in the material. Central to recovery is the formation and evolution of subgrains, which is also recognized as a recrystallization precursor. In this paper, subgrain coarsening is investigated
Situating this presentation in experiences and reflections around changing conditions for doing feminist research, I will illustrate examples of the increased violent and aggressive enactments by neo-Nazi and neo-fascist actors taking place in the academy during the last years. I will recognize the fluidity and interchangeability between digital platforms and non-digital spaces, highlighting alter
In this paper, we have studied the sensitivity of the ESSnuSB far detector to supernova neutrinos. ESSnuSB is a proposed long-baseline neutrino experiment in Sweden, which will use a 538 kt water Cherenkov detector to probe the leptonic phase δCP by studying the second oscillation maximum. However, given the very large detector volume, it will have an excellent sensitivity to supernova neutrinos i
Grain rotation under concurrent grain boundary (GB) migration can be observed in experiments, but poses a challenge in simulations. The need to resolve atom-scale structures while tracing GB migration over extended time scales defy most modeling approaches, including molecular dynamics (MD). In this work, phase field crystal (PFC) modeling is adopted as it permits the required combination of high
This thesis investigates the use of performance bounds in radar signal processing, with particular emphasis on the Cramér-Rao bound (CRB) and its misspecified and Bayesian variants, the MCRB and the BCRB. These bounds characterize fundamental limits on estimation accuracy and can therefore be used to assess the performance attainable under a given signal model. However, they can also be used prosp
Bird flight conversion efficiency (η) determines the amount of metabolic power (Pmet) transformed into mechanical power (Pmech) to remain aloft, and it is central to understanding animal flight energetics, yet it remains difficult to quantify. Using 13C-labelled sodium bicarbonate (NaBi) and particle image velocimetry (PIV), we measured Pmet and Pmech, respectively, in un-instrumented barn swallow
Background: Adenosquamous carcinoma of the pancreas (ASCP) is a rare and aggressive subtype of pancreatic cancer with a dismal prognosis. Futility in ASCP has been inadequately studied. The aim is to assess the incidence of futility in ASCP cases within a European cohort. Methods: Retrospective, multicenter European study including all consecutive patients who underwent surgery for ASCP between 20
Recent observations by the James Webb Space Telescope (JWST) have indicated the presence of water in the inner regions of the disc around the young protostar PDS 70, but the origin of this water remains unclear. Here we report the discovery of variable absorption lines of neutral sodium in archival High Accuracy Radial velocity Planet Searcher (HARPS) spectra of PDS 70. These lines vary strongly a
TiSe2 has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically be expected, while a lack of "smoking-gun"signatures for the importance of the electron-hole interaction in driving the phase transition has rendered it challenging to distinguish the EI from the conventional charge-density
Viruses are ubiquitous in all environments and impact host metabolism, evolution, and ecology, although our knowledge of their biodiversity is still extremely limited. Viral diversity from genomic and metagenomic datasets has led to an explosion of uncultivated virus genomes (UViGs) and the development of specialized databases to catalog this viral diversity, though many lack comprehensive integra
