This study presents a knowledge-driven approach to geological map compilation, focusing on improving the efficiency and accuracy of geological map-making in the Tibetan Plateau. The Geological Compiling & Map-making (GCM) toolkit, developed to integrate data- and knowledge-driven methodologies, automates data processing and geological feature representation. By leveraging expert geological knowledge, this approach minimizes manual labor and reduces time while maintaining high precision in geological interpretation. The results demonstrate significant advancements in GCM efficiency and accuracy, highlighting the potential of knowledge-driven techniques to make geological map. The knowledge-driven technique offers geologists an improved solution for diverse geological maps making.

Based on (1.0087±0.0044)×1010 J/ψ events collected with the BESIII detector at the BEPCII e+e− storage ring, we search for KS0 invisible decays via the J/ψ → KS0 KS0 process. No significant signal is observed, and the upper limit of the branching fraction of these invisible decays is set at 8.4 × 10−4 at the 90% confidence level. This is the first experimental search for KS0 invisible decays. Copyright © 2025, The Authors. All rights reserved.

A measurement of the number of J/ψ events collected with the BESⅢ detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to be（223.7±1.4）×10^6, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESⅢ software. The number of J/ψ events taken in 2012 is determined to be（1086.9±6.0）×10^6. In total, the number of J/ψ events collected with the BESⅢ detector is measured to be（1310.6±7.0）×10^6, where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible.

The motion state of the ocean surface is changeable and has special irregularity. It is impossible to describe these characteristics in detail, which leads to the low accuracy of simulation for the sea surface. A simulation method of realistic dynamic ocean surface based on 3D sonar image algorithm is proposed. The number of adjacent points iteration of two adjacent images is calculated, and all the dynamic shallow surface sonar images are matched and combined. According to the edge coordinate information between the nearest adjacent images, the overlapping part between the two sonar image frames is analyzed. The two frames of sonar images beyond the threshold range of overlap are registered by ICP algorithm, The simulation of the dynamic ocean surface with the statistical model and FFT based wave generation method is carried out. The simulation results show that the research method of 3D sonar image algorithm is more accurate and can achieve more real simulation results.

Aiming at the problem of eliminating the influence of channel interference on the detection results in the process of using sonar to detect very shallow water targets, a sonar image reconstruction method based on adaptive compensation of very shallow water acoustic channel features is proposed. Standard acoustic source and remote server are used to complete the adaptive calibration process of channel characteristic parameters before detection. The calibrated channel characteristic parameters are used in the subsequent beamforming algorithm to compensate the channel interference. The time-of-flight parameters calculated by the compensation algorithm are used in the subsequent point cloud generation and image reconstruction. Simulation and field test show that the proposed compensation method can improve sonar target detection ability by 25% in very shallow water and complex acoustic channel environment, and the quality of sonar image reconstruction is significantly improved.

By analyzing 4.5 fb−1 of e+e− collision data accumulated with the BESIII detector at center-of-mass energies ranging from 4599.53 MeV to 4698.82 MeV, we report the measurement of the absolute branching fraction (BF) of the inclusive decay Λ+c → KS0X using the double-tag technique. The result is B(Λ+c → KS0X) = (10.9 ±0.2 ±0.1)%, where the first uncertainty is statistical and the second is systematic. This result indicates that there are still undiscovered decay channels containing KS0 in the final state with a combined BF of (3.1 ± 0.4)%. The BF of the inclusive decay Λ+c → K0/K0X is calculated to be B(Λ+c → K0/K0X) = (21.8 ±0.4 ±0.2 ±1.1)%, where the third uncertainty accounts for a possible difference between B(Λ+c → KS0X) and B(Λ+c → KL0X). The result is in agreement with the prediction of the statistical isospin model. © 2025, CC BY.

In order to solve the practical operation training problem of an optical sighting telescope in certain weapon system, the application research of simulated target technology is carried out. According to the tactical and technical characteristics of sight and battlefield target, based on the embedded simulation framework, a series of simulation target technologies, such as constructing the optical characteristic model of target, fitting the target trajectory, encapsulating the characteristic information of target in the typical scene, are used to explore the technical route of actual combat training relying on actual equipment and simulation target, and realize the training scene and its model. The application results show that the method is feasible.

Based on a data sample of (10087 ± 44) × 106 J/ψ events taken with the BESIII detector, we search for the flavor-changing neutral current charmonium decay J/ψ → D0µ+µ− + c.c.. No significant signal above the background is observed, and the upper limit on its branching fraction is set to be B(J/ψ → D0µ+µ− + c.c.) Copyright © 2025, The Authors. All rights reserved.
