Enterprise Compliance Risk Identification and Economic Management Optimization Based on Dynamic Bayesian Network

Engineering Reports, Volume 8, Issue 1, January 2026.
This study demonstrates the significant value of a collaborative framework integrating DBN and DRL for enterprise compliance risk identification and economic management optimization. The proposed approach not only overcomes the limitations of traditional models in dynamic risk modeling but also achieves synergistic optimization of risk control and ...

Sizes of Active Galactic Nucleus Inhomogeneous Disks—Large in Microlensing, Small in Reverberation Mapping

The Astrophysical Journal
Magnetohydrodynamic turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly inhomogeneous and has a half-light radius larger than the static Shakura and ...

The Effect of Electroosmosis on the Peristaltic Transport of Eyring Powell Fluid: Bifurcation Analysis of the Non‐Linear Dynamical System

Engineering Reports, Volume 8, Issue 1, January 2026.
The mathematical investigation aims to study the physiological flow inside the channel with an electric double layer (EDL) of zeta potential. The flow is assumed to be in a horizontal two‐dimensional channel containing Eyring Powell fluid like blood at a specific temperature.

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Active Flow Control of the Magnetohydrodynamic Flow in an Annular Linear Induction Pump by Modifying the Driving Electromagnetic Field

International Journal of Energy Research
The strong coupling between fluid and electromagnetic field in the annular linear induction pump (ALIP) can gradually amplify small disturbance in the fluid field into large‐scale vortices. The appearance of the vortices seriously affects the efficiency and reliability of the pump.

Climatology of Medium‐Scale Traveling Ionospheric Disturbances Over Continental US Using GNSS TEC From 2012 to 2023

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.

How Does the Critical Torus Instability Height Vary with the Solar Cycle?

The Astrophysical Journal
The ideal magnetohydrodynamic torus instability can drive the eruption of coronal mass ejections. The critical threshold of magnetic field strength decay for the onset of the torus instability occurs at different heights in different solar active regions,
