Structural Optimization of 3D Braided Tungsten–Copper Composites via Active Learning and Finite Element Simulation

Materials Genome Engineering Advances, Volume 4, Issue 2, June 2026.
An uncertainty‐aware FEM–GPR active learning framework efficiently explores the design space of 3D braided W–Cu composites, identifying architectures with higher yield strength and preserved electrical conductivity, whereas SHAP interpretation highlights yarn spacing in the braid plane as the key structural factor controlling composite performance ...

Prediction for Arrival Time and Parameters of Corotation Interaction Regions using Earth–Mars Correlated Events from Tianwen-1, MAVEN, and Wind Observations

The Astrophysical Journal
Using the Stream Interaction Regions list from the Tianwen-1/Mars Orbiter Magnetometer (MOMAG) data between 2021 November and 2021 December and from Wind observations, we present an accurate prediction for the arrival time and in situ parameters of ...

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, Volume 2, Issue 2, June 2026.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Rotation‐Controlled Diurnal Evolution of Uranus' Asymmetric Bow Shock at Equinox

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Uranus possesses the most extreme magnetic and rotational geometry in the solar system, resulting in a uniquely dynamic and asymmetric interaction between its magnetosphere and the solar wind. Here we investigate the diurnal evolution of the Uranian bow shock (BS) at equinox using global multifluid magnetohydrodynamic simulations constrained ...

Risk Factors and Comparative Safety of Anti‐PD‐1 Combination Therapies in Advanced Melanoma: A Nationwide Real‐World Cohort Study From China

Cancer Medicine, Volume 15, Issue 4, April 2026.
ABSTRACT Backgroud Different anti‐PD‐1 combination therapies are used to improve response rate and combat drug resistance for melanoma in the real world of China. While the reported safety data has remained scarce, especially for the controversial use of interferon.

Mars Gravity Field Determination Using Tianwen-1 Orbiter Tracking Data

The Astrophysical Journal Letters
The Martian gravity field is a key data set for studying the internal structure of Mars. For this purpose, we processed all the two-way Doppler tracking data of the Tianwen-1 orbiter from 2021 June to 2024 October and determined a new degree and order 80

Magnetic Reconnection as a Potential Trigger for Magnetotail Flapping at Mars: Insights From MAVEN and Tianwen‐1 Observations

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Magnetotail current sheet (CS) flapping is a universal plasma phenomenon observed at multiple planets, yet its triggering mechanisms remain poorly understood outside of Earth. At Mars, single‐spacecraft observations have also reported tail flapping, but the processes responsible for its onset have never been identified.

Magnetosphere of Mars at Almost Radial Interplanetary Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We have studied the structure of the Martian magnetosphere under conditions of an almost radial interplanetary magnetic field (IMF). Under such conditions, the currents driven by the motional electric field −1cVsw×BIMF ${-}\frac{1}{c}{\mathbf{V}}_{sw}\times {\mathbf{B}}_{\mathit{IMF}}$ are expected to be strongly reduced, and the induced ...
