Optimization of Microhole Morphology in Electrolytic Abrasive Jet Machining
type: item
description: To address issues such as thick recast layers, high pore wall roughness, and dif-ficult-to-control geometric accuracy during micro-hole machining of nick-el-based high-temperature alloy 718, a laser-electrochemical hybrid processing method assisted by abrasive jet is proposed. By establishing a synergistic “electrolyte abrasive jet-nanosecond laser” processing system, combined with multiphysics coupling simulation and experimentation, this study system-atically investigates the influence mechanisms of parameters such as jet veloci-ty, jet angle, abrasive particle size, and voltage on microhole roundness, taper, wall roughness, surface morphology, and recast layer formation. Results indi-cate that moderate jet and electrical parameters significantly enhance orifice morphology and wall quality while effectively suppressing microcracks and re-cast layers. Orthogonal experiments optimized the following optimal process parameters: jet velocity 8 m/s, jet angle 60°, abrasive particle size 15 μm, voltage 15 V, and current 3 A. Under these parameters, the micro-hole round-ness, surface morphology, and taper achieved optimal values, while hole wall roughness was significantly reduced and surface quality markedly improved.

The Synergistic Effect of Waterjet Assistance and a Novel Line-Delay Strategy on Precision Laser Drilling of Inconel 718
type: item
description: This study investigates the optimization of process parameters for waterjet-assisted nanosecond laser drilling of Inconel 718, with a focus on improving microhole quality through pulse delay strategies and defocus control. Experi-ments were conducted using concentric circular scanning under both underwa-ter and in-air conditions, with emphasis on the effects of delay methods—specifically face-delay and line-delay—on geometric accuracy and morphologi-cal integrity. Results indicate that the line-delay approach significantly reduces entrance diameter, taper, microcracks, and oxidation compared to non-delayed and face-delayed conditions. The ablation threshold increased from 12.58 J/cm² in air to 22.12 J/cm² underwater due to energy attenuation effects. Optimal machining quality was achieved with a defocus distance of –0.5 mm, corre-sponding to focal positioning near the workpiece center. The study demon-strates that waterjet-assisted laser drilling with adaptive pulse delay effectively enhances machining precision and surface quality, showing great potential for applications in high-temperature component manufacturing.

Experimental Study on Laser Pulse Delay Machining of IN718 Assisted by Chemical Liquid
type: item
description: IN718, a typical nickel-based superalloy, is widely used in critical components such as aero-engine turbine blades and combustion chambers due to its excel-lent high-temperature strength, creep resistance, and corrosion resistance. However, the material's high-temperature strength deficiency, low thermal conductivity, and poor plasticity lead to low efficiency in conventional ma-chining processes and severe tool wear. Laser machining, with its advantages of high energy density, non-contact processing, and flexibility, is regarded as an effective method for machining micro-holes in superalloys. Nevertheless, laser micro-hole machining in ambient air still faces challenges such as oversized hole diameters, rough hole walls, wide heat-affected zones, and thick oxide layers. To address these issues, this study proposes the use of a chemical-assisted machin-ing environment combined with a pulse delay technique, aiming to thoroughly investigate its mechanism and effectiveness in the micro-hole machining of IN718 alloy.

Reservoir Characteristics of the Chang 63 Sub-member in the Daluogou Area
type: item
description: The Chang 6 reservoir is characterized by "five lows and one strong": low porosity, low permeability, low temperature, low pressure, low oil saturation, and strong heterogeneity. With the continuous and in-depth development of the tight oil reservoir in the Chang 6 formation of the Dagugou area, the natural energy depletion development method has led to severe formation energy deficit, rapid production decline, and difficulties in maintaining stable production, which have become "bottlenecks" restricting the sustainable development of this area. Deepening the understanding of the Chang 6 formation in the Dagugou area through reservoir characteristic research is an effective approach to break through the development bottlenecks and achieve increased and stable production. This study utilizes scanning electron microscopy, cast thin sections, high-pressure mercury intrusion, physical property analysis, oil-water two-phase flow experiments (unsteady-state), and nuclear magnetic resonance movable fluid experiments to investigate diagenesis, reservoir physical properties, and pore structure. It analyzes the microscopic pore structure characteristics of different parts of the sand body and different sand belts, examines the controlling factors influencing reservoir physical properties, conducts a comprehensive reservoir evaluation, and maps the planar distribution of reservoir physical properties to determine the distribution patterns of high-quality reservoirs. This provides theoretical guidance for the subsequent development of the tight oil reservoir in the Chang 6 formation of the Dagugou area.

Research on Route Optimization of Fresh Food Distribution to Residential Areas in Emergency Scenarios
type: item
description: When cities are hit by sudden public safety incidents such as natural disasters, toxic gas leaks, extreme air pollution and epidemics, the daily supply of fresh food for residents cannot be guaranteed. This paper constructs a multi-center demand-splittable model for residents' material distribution in emergency scenarios, aiming to solve the problem of distributing materials from urban emergency warehouses to residential areas in controlled zones. The comprehensive objectives of this model are to minimize the total distribution time and make full use of the service capabilities of each distribution center. Through case analysis, an improved genetic algorithm is used to solve the proposed model. The results show that the distribution scheme can comprehensively utilize the service capabilities of various distribution centers, ensure the efficient delivery of fresh food, and thus has practical significance.

Causal Meta-Learning for Few-Shot Threat Detection in NIDS
type: item
description: In the realm of Network Intrusion Detection Systems (NIDS), detecting novel threats like zero-day attacks or variants poses significant challenges due to the scarcity of labeled samples and the difficulty in rapid model adaptation. This paper introduces a causal meta-learning framework based on Model-Agnostic Meta-Learning (MAML) to enable few-shot threat detection. The core innovation lies in incorporating causal invariance constraints into both the inner and outer loops of MAML, allowing the model to learn how to adapt quickly using causally invariant features that remain stable across varying threat distributions. By leveraging counterfactual reasoning and invariant risk minimization, the model disentangles causal factors from spurious correlations, enhancing robustness and generalization. Experimental evaluations on benchmark datasets, such as NSL-KDD and CIC-IDS2017, demonstrate superior performance in few-shot scenarios, achieving up to 10% higher detection accuracy compared to standard meta-learning baselines. This approach holds promise for real-time NIDS in dynamic environments, paving the way for more resilient cybersecurity defenses.

Seed germination characteristics of Phoebe sheareri (Hemsl.) Gamble
type: item
description: The germination characteristics of fresh seeds of Phoebe sheareri (Hemsl.) Gamble was investigated under three different treatments (gibberellin treatment, stratification treatment, seed removal treat-ment). Observations: after soaking seeds with different concentrations of gibberellin solution (0mg/L, 500mg/L, 1000mg/L, 1500mg/L) for 24h, the seed germination experiment showed that 1500mg/L gib-berellin treatment resulted in the best germination for P. sheareri (Hemsl.) Gamble seeds, with germi-nation percentage and germination potential (average of three replicates) reaching 82% and 71% re-spectively, among the highest across all treatments. Among the three stratification treatments (room temperature stratification, 4℃low temperature stratification, and 25℃to 5℃temperature stratifica-tion), the 25℃to 5℃ temperature stratification treatment significantly promoted P. sheareri (Hemsl.) Gamble seed germination, with a seed germination percentage reaching 34% within half a month, far higher than the germination percentages of other stratification treatments. The seeds of P. sheareri (Hemsl.) Gamble without seed shells did not germinate on the 20th day of the germination experiment, and the experiment also indicated that the water The permeability of the seeds was better, so the seed shell had no effect on the germination of the seeds.

Superhydrophobic HWCNTs/EP composite coating with anti-icing and photothermal deicing properties
type: item
description: Photothermal superhydrophobic surfaces have garnered significant attention for their exceptional anti-icing and photothermal deicing capabilities. However, the shortcomings of stability and fabrication complexity limit their practical application. This work designed and fabricated a HWCNTs/EP composite coating that combines anti-icing/deicing performance, and facile preparation. During fabrication, the HWCNTs and EP ratio was systematically optimized by evaluating wettability, photothermal conversion capability, and anti-icing/deicing performance. The composite coating in the ratio of HWCNTs/EP 1:1 exhibited a water CA of 156.7°. Photothermal testing revealed a maximum temperature increase of 69 ℃ (reached in 200 s) under one sun intensity. The composite coating demonstrated a prolonged droplet freezing time of 1026 s at −15 ℃. Photothermal deicing testing achieved complete ice melting and detachment within 44 s. This work provides novel insights for designing stable photothermal superhydrophobic coatings with anti-icing/deicing functionality, contributing to the development of energy-efficient ice mitigation technologies.

Research on Mineral Inversion Method Based on Elemental Logging
type: item
description: The elemental data and mineral data obtained from elemental logging and X-ray diffraction were used to invert the mineral content through five methods. The oxide closure model method is based on the theoretical stratigraphic model, and the core condition of setting the sum of the mass percentages of clay minerals, carbonates, and the quartz-feldspar-mica mixture (QFM) to 100% is used for modeling and solving. The non-negative least squares method, truncated singu-lar value decomposition method, and linear programming method are based on the conversion relationship model between elements and minerals proposed by Herron. Through the analysis of the lithological characteristics of the block, the element content inversion mineral content model is established based on the matrix solution method. The XGBoost machine learning algorithm automatically learns and captures the complex relationships between samples from the data samples to solve the problem. Taking well x as an example, the mineral content was calculated through the five inversion methods. The comparison of the cal-culation results with the whole rock analysis results shows that the variation trends of each method with the depth of the stratum are basically consistent with the whole rock analysis results. Among the four mineral inversion meth-ods, the processing result of the XGBoost machine learning algorithm is the best, with a mean square error of 0.91; the processing effects of the non-negative least squares method and the truncated singular value decomposition method are second, with mean square errors of 0.88 and 0.81, respectively; the mean square error of the linear programming method is relatively low, only 0.79.

Target Detection Algorithm for UAV Aerial Images Based on IRE-YOLO
type: item
description: To address challenges in UAV aerial images such as a high proportion of small objects, complex backgrounds, significant scale variations, and limited computing resources, this study proposes an improved object detection algorithm based on YOLOv11n—namely, IRE-YOLO. In the backbone network, the algorithm introduces the inverted residual mobile block (iRMB) attention mechanism to enhance the model's ability to extract features of small objects in complex backgrounds. It replaces some standard convolutions with depthwise separable convolutions (DSConv) to reduce the number of parameters while maintaining feature expression capability. In the neck network, an efficient upsampling block (EUCB) is designed to recover detailed information through hierarchical feature reconstruction, thereby improving the representation quality of small objects' edges and textures. Experimental results on the DOTA dataset show that IRE-YOLO outperforms mainstream lightweight models in key metrics including precision (P), recall (R), mAP@50, and mAP@50:95, achieving 69.4%, 59.0%, 61.0%, and 34.2% respectively. Meanwhile, the model's parameter count is reduced to 8.7MB, realizing an effective balance between accuracy and lightweight design. The research demonstrates that IRE-YOLO has high practical value in small object detection tasks for UAV aerial images and provides a feasible solution for real-time deployment on embedded platforms.

Design of a tandem ankle rehabilitation robot
type: item
description: Impaired ankle function resulting from various diseases and sports-related inju-ries is a prevalent clinical concern, significantly affecting patients’ mobility and quality of life. In response to the growing demand for effective rehabilita-tion solutions, this paper presents a novel serial-structured ankle rehabilitation robot (ARR) based on emerging robotic technologies and existing rehabilitation products. Taking into account the anatomical movement patterns and physio-logical range of motion of the ankle joint (AJ), a three-dimensional mechanical model was carefully designed to closely mimic natural joint kinematics. A func-tional prototype was developed, and experimental tests were conducted to evaluate key performance metrics, including speed response and positioning accuracy. The results demonstrated that the robot exhibits stable and responsive motion control with high precision. Furthermore, the Anybody simulation soft-ware was employed to assess the activation levels of major muscles involved in ankle movement during robotic-assisted training. The data revealed significant engagement of the targeted musculature, indicating effective muscle stimula-tion. Overall, the proposed ARR shows great potential to fulfill the essential re-quirements of ankle joint rehabilitation training.

Experimental Investigation on the Mechanism of Cutting Performance Enhancement of YG8N Cemented Carbide Tools with Tesla-Valve-Inspired Micro-Textures under MoS₂-Based Minimum Quantity Lubrication
type: item
description: To improve the wear resistance, heat dissipation and anti-adhesion capability of cemented carbide tools in machining titanium alloys, Tesla-valve-inspired anisotropic micro-textures were fabricated on the rake face of YG8N cemented carbide tools using femtosecond laser processing. Cutting experiments were carried out under MoS₂-based hybrid minimum-quantity lubrication (MQL). A tri-axial piezoelectric dynamometer, temperature sensors and surface characterization techniques were employed to systematically compare non-textured tools, forward-textured tools and reverse-textured tools at low (300 mm/s) and high (1000 mm/s) cutting speeds in terms of cutting force, friction coefficient, temperature distribution, tool wear and chip morphology. The results show that: the micro-textures significantly reduce the actual contact area between the tool and the workpiece and enhance both the storage and transport of cutting fluid, thereby improving lubrication and cooling conditions; at high cutting speeds, the forward-textured tool achieves reductions of about 28.1% in cutting force and 50% in friction coefficient compared with the non-textured tool, lowers the tool-tip temperature by roughly 50% and decreases the wear-band width by about 70%; the micro-textures promote chip curling and evacuation, suppressing the formation of built-up edge and adhesion layers and thus markedly extending tool life. This study elucidates the synergistic mechanism of lubrication and heat dissipation by Tesla-valve-inspired micro-textures in enhancing cutting performance, and provides both theoretical and experimental support for the design of high-performance cemented carbide cutting tools.

Friction Properties of PEEK under Different Lubrication Conditions
type: item
description: This study employed PEEK test blocks paired with 45# steel balls to conduct controlled variable tests using a self-made reciprocating friction and wear testing machine, systematically investigating the tribological behavior of PEEK materials under dry friction, wet lubrication, and three different water-lubricated conditions. The friction and wear mechanisms were thoroughly analyzed through surface morphology characterization. The results demonstrate that PEEK exhibits optimal tribological performance under soup-like water lubrication at a rotational speed of 100 r/min (linear velocity: 33.3 mm/s) and a load of 50 N. This research provides critical data support and theoretical guidance for the application of PEEK composites in water-lubricated bearings and guide rail materials for garbage truck compression devices.

Design and Experimental Study of an Electrically-Driven Seed Metering Control System for Intelligent Agriculture
type: item
description: In order to overcome the limitations of traditional seeders, including inadequate operational accuracy, unsatisfactory seeding performance, and low levels of automation, an intelligent control system for a pneumatic precision seeder was developed. The system is centered on a self-designed main controller, which acquires real-time operating speed through a speed measurement module and dynamically adjusts the seed metering device`s rotational speed according to the preset seeding parameters, thereby achieving high-precision precision seeding. This not only effectively reduces seed wastage and production costs during the operation, but also significantly enhances the level of operational intelligence. Experimental results show that the seeding qualification rate of the control system exceeds 95%, with a missed seeding rate below 3%. The system can stably realize turning compensation, thereby further ensuring the uniformity and reliability of the operation.

A Review on Photocatalytic Oil/Water Separation Membranes Based on Ti-MOFs
type: item
description: The escalating global issue of oil-water pollution demands advanced separation technologies that combine efficiency, sustainability, and reusability. Titani-um-based metal-organic frameworks (Ti-MOFs) have emerged as promising candidates due to their unique structural and functional properties. This review systematically examines the design, fabrication, and application of Ti-MOFs for oil-water separation, highlighting their superior attributes, including exception-al chemical stability, photocatalytic self-cleaning capability, and tunable wetta-bility. Key fabrication strategies such as in situ growth, physical compositing, and interfacial crosslinking are discussed, with emphasis on optimizing mem-brane performance through hierarchical pore engineering and heterojunction coupling. Practical applications demonstrate their efficacy in industrial wastewater treatment and marine spill remediation. Despite these advances, challenges remain in scalable synthesis and long-term stability under harsh conditions. Future directions include multifunctional membrane design and ecological impact assessments to facilitate real-world deployment. Ti-MOFs represent a transformative approach to sustainable oil-water separation, bridg-ing the gap between laboratory innovation and industrial implementation.
