4+ hour, 26+ min ago   (347+ words) The delineation of mineralized zones within deposits is inherently associated with geological uncertainty, directly impacting resource-reserve estimation and eventual extraction. This study presents a comparative analysis of three geological modeling techniques, including Indicator Kriging (IK), Nearest Neighbor (NN), and Multilayer…...

5+ hour, 21+ min ago   (409+ words) Wall thinning caused by corrosion changes the circumferential strain response of storage tanks, but nonlinear coupling among structural parameters, loading conditions, strain characteristics, and defect geometry makes direct inversion difficult. This paper develops a strain-based, finite element (FE)-based machine…...

8+ hour, 13+ min ago   (443+ words) Spearmint is a medicinal and aromatic crop vulnerable to several diseases, and its cultivation relies heavily on chemical inputs, which can alter phytonutrient quality and raise environmental and health concerns. To address this, the current study focused on developing a…...

8+ hour, 46+ min ago   (596+ words) Multi-station global navigation satellite system (GNSS) displacement-residual forecasting may benefit from neighbouring stations, yet unrestricted spatial aggregation can obscure station-local temporal dynamics and the independent value of spatial information. Whether neighbouring stations provide additional predictive information after a strong station-local…...

8+ hour, 46+ min ago   (447+ words) Post-activation performance enhancement (PAPE) is often attributed to elevated neural drive, yet neuromuscular and mechanical responses are rarely tracked concurrently. This study examined whether the two scale proportionally over the 1–4 min following a conditioning activity, with a maximal countermovement jump…...

9+ hour, 24+ min ago   (468+ words) To clarify the water-sensitive deterioration mechanisms of red-bed soft rocks under repeated wetting–drying cycles, mudstone samples from two representative sites in the Sichuan Basin were investigated through multiscale experiments combining mechanical testing, X-ray diffraction (XRD), and scanning electron microscopy…...

9+ hour, 24+ min ago   (591+ words) During the frequent charging, discharging, and storage processes of underground compressed air energy storage systems, the damage and degradation of sealing plugs directly affect the long-term stability of gas storage caverns. Using a self-developed cyclic charging–storage–discharging–restorage gas…...

9+ hour, 24+ min ago   (678+ words) Mapless deep reinforcement learning (DRL) navigation in dynamic indoor environments is difficult under single-frame 2D LiDAR, which reports where an obstacle is but not whether it is approaching. We introduce the Positional-Velocity Spatio-Temporal Attention Module (PV-STAM), a compact perception block (19,968 trainable…...

9+ hour, 46+ min ago   (421+ words) Proton-exchange membrane fuel cell degradation is one of the factors that limit the deployment of this technology in the automotive market. Accelerated Stress Tests (ASTs) are the standard tool for assessing durability during design and development phases, thanks to their…...

10+ hour, 13+ min ago   (259+ words) The dynamic response of soft terrain under repeated vehicle passes significantly influences off-road vehicle mobility and performance. The primary innovation of this research is the integration of loading–unloading hysteresis, multi-pass terrain-state evolution, and sensitivity analyses within a unified HSSTM-based…...
