Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves

Astronomische Nachrichten, EarlyView.
ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

Thermal Radiation Transport with Tensor Trains

The Astrophysical Journal
We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the specific intensity.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Roles of 2D halide perovskites in 2D/3D heterojunctions for high‐performance perovskite solar cells

Bulletin of the Korean Chemical Society, EarlyView.
This review establishes a design framework for two‐dimensional (2D)/three‐dimensional (3D) perovskite heterojunctions, redefining the 2D perovskite layer as an active semiconductor component. We classify 2D structures by spacer chemistry and analyze their roles within the heterojunction.

Probing the Influence of Sulfur–Aromatic Interactions on the Electronic Structure of Gas‐Phase Peptides

Chemistry – A European Journal, EarlyView.
Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...

Proton–proton fusion in lattice effective field theory

Physics Letters B, 2015
The proton–proton fusion rate is calculated at low energy in a lattice effective field theory (EFT) formulation. The strong and the Coulomb interactions are treated non-perturbatively at leading order in the EFT.

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Synthesis of Single‐Crystalline Ni‐Rich Cathodes for Lithium‐Ion Batteries With Superior High‐Voltage Stability by Mo/Nb Dual Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel synthesis method of single‐crystalline LiNi0.8Co0.15Al0.05O2 (NCA) is introduced, involving the stripping of grain boundaries from polycrystalline NCA (PC‐NCA) during Mo/Nb co‐doping. Mo doping near the grain surface significantly reduces parasitic interface reactions and inhibits the excessive growth of CEI films, while Nb doping within the ...

Benchmarking Hybrid CNN‐Transformer Versus Pure Transformer Architectures for Accelerated Hyperpolarized 129Xe MRI Reconstruction

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Hyperpolarized 129Xe MRI faces technical challenges including low signal‐to‐noise ratio and breath‐hold constraints. Current literature focuses on proprietary deep learning methods or image‐domain enhancements. Purpose To present a comprehensive evaluation of transformer and hybrid CNN‐transformer architectures integrating dual ...
