The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, EarlyView.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks

Chemistry–Methods, EarlyView.
The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, EarlyView.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator

Laser &Photonics Reviews, EarlyView.
An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3

physica status solidi (b), EarlyView.
The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Generation of Curvature Perturbations with Extra Anisotropic Stress

, 2010
We study the evolution of curvature perturbations and the cosmic microwave background (CMB) power spectrum in the presence of an hypothesized extra anisotropic stress which might arise, for example, from the dark radiation term in brane-world cosmology ...

Scaling of precipitation extremes with surface temperature in western Canada: Understanding the control factors using a convection‐permitting climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution convection‐permitting climate model simulations have been successfully utilized to investigate the relationships between precipitation extremes and temperature (PT scaling) in western Canada. This makes it possible to further examine the relationships between precipitation extremes and other atmospheric conditions, such as column water ...
