LSOS: An FG Position Method Based on Group Phase Ranging Ambiguity Estimation of BeiDou Pseudolite

open access: yesRemote Sensing, 2023
Due to the influence of indoor space environments, the carrier phase information obtained by the BeiDou pseudo-satellite often has the issue of cycle slips, which makes the user unable to carry out high-precision positioning.

Immune Response and Gut Microbiota Shift in the Red Palm Weevil (Rhynchophorus ferrugineus) Infected With Entomopathogenic Fungus, Beauveria bassiana, Reveal Host‐Pathogen Interactions

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 2, June 2026.
This study reveals a “Microbiota‐Immune Axis” in Beauveria bassiana‐infected larvae, where gut dysbiosis positively correlates with systemic immunity in the fat body. Meanwhile, the hindgut exhibits immune tolerance, highlighting a tissue‐specific trade‐off between combating the pathogen and preserving the gut microbiome.

Waste‐Derived Functional Carbon for Rapid PAHs Removal: A Sustainable Pathway for Co‐Remediation and Resource Valorization of Oily Sludge

open access: yesSusMat, Volume 6, Issue 3, June 2026.
Oily sludge is converted into co‐pyrolytic carbon (CPC) through co‐pyrolysis with biomass and further functionalized with APTES to form APTES/CPC. The modified carbon enables rapid anthracene removal from petroleum‐contaminated wastewater, achieving most adsorption within 1 min and reaching equilibrium within 10 min. The enhanced adsorption performance

Accurate Ionospheric TEC Prediction With a Causal Attention Network at Northern EIA Crests

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract As the Sun approaches the peak of its 25th activity cycle, precise ionospheric forecasting has become increasingly challenging. Low‐latitude regions have emerged as a persistent bottleneck for space weather operations. Extensive evidence reveals that existing AI models exhibit significant performance degradation in these regions, demonstrating
