Optimal Control Applications and Methods, Volume 46, Issue 6, Page 2829-2842, November/December 2025.ABSTRACT This study proposes a semi‐analytical guidance strategy for gliding vehicles by integrating proportional navigation (PN) with sparse waypoint optimization to maximize terminal velocity. Utilizing the analytical solution of PN with a navigation constant of three, the original optimal control problem is transformed into a low‐dimensional ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The JUpiter ICy moons Explorer (JUICE) mission, launched by the European Space Agency (ESA) in April 2023, aims to explore Jupiter and its icy moons, particularly focusing on Europa, Ganymede, and Callisto. This study uses the Latmos Hybrid Simulation (LatHyS) model to simulate Europa's plasma and field environment, emphasizing the upcoming ...

Intra‐Island Variation in Wind Patterns on Sub‐Antarctic Marion Island
Geoscience Data Journal, Volume 12, Issue 4, October 2025.Wind speed and direction measurements, over ca. 3 years, were used to inform and validate computational fluid dynamics simulations of wind across Marion Island at a high spatial resolution. The measured and simulated data show high directional variability in wind conditions in the five different geographical sectors on the island.

Extending Excitation Time for Detonation Prevention: Mixture Effect in Dimethyl Ether Auto‐Ignition
International Journal of Chemical Kinetics, Volume 57, Issue 10, Page 589-606, October 2025.ABSTRACT Undesired detonation development is an obstacle in the development of modern combustion systems based on auto‐ignition. Excitation time is one of two time scales that affect detonation development. It describes the time interval, during which heat is released.

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.Abstract Global numerical modeling is advancing into the era of kilometer‐scale, non‐hydrostatic simulations, while heterogeneous computing emerges as a pivotal trend in high‐performance computing (HPC). As a strong candidate for next‐generation global kilometer‐scale general circulation models, the A‐grid dynamical core based on the Low Mach number ...

Coherence of Coupling Conditions for the Isothermal Euler System
Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11565-11591, August 2025.ABSTRACT We consider an isothermal flow through two pipes. At the junction, the flow is possibly modified by some devices, such as valves, compressors, and so on, or by the geometry of the junction; coupling conditions between the traces of the flow must be given.

Interpreting Energy‐Latitude Dispersions in Mercury's Northern Magnetospheric Cusp With MESSENGER
Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract We examined energy‐latitude dispersions in Mercury's northern magnetospheric cusp. These systematic trends in plasma energy originate from differences in particle travel time from the dayside magnetopause reconnection site to the low altitude, high latitude cusp.

The finite element method in low speed aerodynamics [PDF]
The finite element procedure is shown to be of significant impact in design of the 'computational wind tunnel' for low speed aerodynamics. The uniformity of the mathematical differential equation description, for viscous and/or inviscid, multi ...
