Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer
Contributions to Plasma Physics, EarlyView.ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

Effect of Magnetic Islands on Neoclassical Heat Diffusivity in a Global Tokamak Simulation
Contributions to Plasma Physics, EarlyView.ABSTRACT Resonant magnetic perturbations (RMPs) alter magnetic field topology via island formation and can modify core transport in toroidal fusion devices. Using the global gyrokinetic particle‐in‐cell code XGC‐S, originally developed for stellarator geometries, we quantify how island topology affects neoclassical heat transport in a circular tokamak ...

Vekerzug culture and new finds of Scythian akinakai in Moravia
Tyragetia, 2017 In 2016 authors of this paper obtained information about three Scythian daggers from the territory of Moravia. They were found by unknown persons with the help of metal detectors in the vicinity of Brno, near Horákovský hrad. The dagger no.

International Journal for Numerical Methods in Fluids, EarlyView.Employing the moving least‐squares aided finite element method (MLS‐FEM) allows detailed thermal analysis in complex porous structures, such as polymeric foams, where the conductive heat transfer mechanism governs in the solid matrix and the convective mechanism dominates within the gas‐filled voids.

Forecasting With Dynamic Factor Models Estimated by Partial Least Squares
Journal of Forecasting, EarlyView.ABSTRACT Dynamic factor models (DFMs) have found great success in nowcasting and short‐term macroeconomic forecasting when incorporating large sets of predictive information. The factor loadings are typically estimated cross‐sectionally with principal component analysis (PCA) or maximum likelihood (ML), which ignore whether the factors have predictive ...

[Introduction to] Civic Virtues: Rights, Citizenship, and Republican Liberalism
, 1997 Dagger states the case for republican liberalism, a political theory that combines a concern for individual rights and autonomy with a concern for the claims of community, duty, and public-spirited citizenship.

Topological Metamaterial for Magnetic Resonance Imaging
Interdisciplinary Materials, EarlyView.This work introduces a wireless, passive topological circuit metamaterial for Magnetic resonance imaging (MRI) that supports dual topological boundary states, enabling superior local radiofrequency field confinement. Planar‐to‐three‐dimensional stacking enhances image signal‐to‐noise ratio across imaging sequences, offering a robust and clinically ...

JCPP Advances, EarlyView.This study found that youth with a higher genetic risk for internalizing and externalizing problems were more likely to face adversity within their home, highlighting the need for risk mitigation. These associations varied by adversity type and timing. Additionally, low family income, parental divorce, and externalizing behaviours were linked to lower ...
