Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Influences of Variable Thermal Conductivity, Viscous Dissipation, and Cattaneo–Christov Heat and Mass Fluxes on MHD Tangent Hyperbolic Ternary Hybrid Nanofluid Flow Over a Stretching Sheet

Engineering Reports, Volume 7, Issue 7, July 2025.
This research examines the heat and mass transfer rates in magnetohydrodynamic (MHD) tangent hyperbolic ternary hybrid nanofluid flow over a stretching plate, considering factors such as variable thermal conductivity, Joule heating, viscous dissipation, chemical reactions, Darcy–Forchheimer flow, Cattaneo–Christov heat and mass fluxes, and nonlinear ...

Research on Lung Sound Signal Image Feature Recognition Based on Temporal and Spatial Dual‐Channel Long‐ and Short‐Term Memory Model

International Journal of Imaging Systems and Technology, Volume 35, Issue 4, July 2025.
ABSTRACT In this paper, through the study on the transformation of lung sound signal into image feature signal processing, we further mastered the processing process of lung sound signal, and used the new neural network model to identify and diagnose the image features of lung sound, effectively improving the effect of clinical AI‐assisted diagnosis ...

Particle Astrophysics and Cosmology: Cosmic Laboratories for New Physics (Summary of the Snowmass 2001 P4 Working Group)

, 2002
The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. Here we summarize some

Deriving Tidal Constituent Estimates From GNSS Buoy Data in the Arctic

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Measurements of tides are relatively sparse in the Arctic. This paper studies GNSS buoy tracks to complement existing data. Existing methods to perform tidal harmonic analysis of the buoy data are inadequate in the Arctic region because these methods for tidal analysis combine data from multiple buoy tracks, which is often infeasible in the ...

Impact of Data Assimilation Frequency and Observation Location in Thermal Effluent Modeling for Coastal Waters

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract This study investigates the application of data assimilation (DA) using the Ensemble Kalman Filter (EnKF) to address the uncertainties associated with modeling the thermal effluents discharged from power and desalination plants into a shallow, tidal bay.

Numerical simulations of multi-scale astrophysical problems: The example of Type Ia supernovae

, 2007
Vastly different time and length scales are a common problem in numerical simulations of astrophysical phenomena. Here, we present an approach to numerical modeling of such objects on the example of Type Ia supernova simulations.

The Ionopause at Mars and Its Correlation With Magnetic Topology and Plasma Pressure

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We utilize Mars Atmosphere and Volatile Evolution (MAVEN) observations to investigate the ionopause boundary at Mars, the formation process of which is not yet well described. We focus on the eighth deep dip campaign (DD8), which consists of 50 consecutive orbits, and we develop an automated routine to identify ionopause boundaries in electron

Diffusive Equilibrium: Modeling Anisotropic Maxwellian and Kappa Field Line Distributions in Io's Plasma Torus Using Multi‐Fluid and Kinetic Approaches

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Modeling density distributions along Jupiter's magnetic field lines is essential for understanding the Io plasma torus, moon plasma interactions, and plasma throughout the magnetosphere. This study compares multi‐fluid and kinetic approaches to diffusive equilibrium and the effects of different plasma distribution functions and anisotropy.

Excitation of Storm‐Time Pc5 ULF Waves During the 22 July 2009 Storm: Comparison of GOES, Ground Observations, and GEMSIS Coupled Simulation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Internally driven ULF waves are excited in the premidnight region during the magnetic storm on 22 July 2009. The excitation of ULF waves was investigated based on the Geospace Environment Modeling System for Integrated Studies (GEMSIS) magnetosphere‐ionosphere coupled model, GOES spacecrafts, and ground magnetometers.
