Comparative Study on Dynamic Mechanical Behavior and Power-Law Versus Johnson–Cook Constitutive Models of Quenched 42CrMo Steel

This study systematically investigates the dynamic mechanical behavior and constitutive modeling of low-temperature quenched and tempered 42CrMo steel under high-strain-rate and high-temperature conditions. Dynamic compression tests were performed using a split Hopkinson pressure...

Restoration of ancient Chinese paintings using GANs with multi-scale defect fusion architecture and multi-pooling enhanced spatial-channel attention

<title>Abstract</title> This study investigates the application of generative adversarial networks combined with multi-scale defect fusion architecture and multi-pooling enhanced channel–spatial in the restoration of ancient Chinese paintings. This approach addresses some challen...

Multi-Objective Optimization of Milling Process Parameters Using MOWOA and Comprehensive Performance Evaluation via AHP-TOPSIS

To achieve the multi-objective collaborative optimization of milling processes, orthogonal experiments are conducted to develop prediction models for vibration acceleration and milling force, and range analysis together with variance analysis are adopted to reveal the sensitivity...

Synergistic Optimization of Plasma-Sprayed Zirconia Coatings: Towards Ultra-High Hardness and Superior Wear Resistance

This study reported on the multi-objective optimization of atmospheric plasma spraying parameters for zirconia coatings by incorporating the response surface method with the desirability method, while simultaneously enhancing microhardness and reducing wear rates. The spraying va...

Does cross-border regulatory cooperation reduce excessive risk-taking?

This study investigates how heightened regulatory scrutiny by the U.S. Securities and Exchange Commission (SEC), caused by the passage of the Multilateral Memorandum of Understanding (MMoU), affects excessive risk-taking by U.S. listed foreign firms. Using data from 37 countries...

Development and internal validation of a nomogram for predicting endometrial polyp recurrence after hysteroscopic polypectomy

Endometrial polyps (EP) are common, and hysteroscopic polypectomy is the reference treatment, but recurrence is frequent. This study aimed to identify risk factors for recurrence and to develop and internally validate a nomogram for individual postoperative risk stratification. I...

UnravelingSulfur Vacancy Evolution Mechanism duringLow-Temperature H2 and S Vapor Annealing in Monolayer Mo(1– x )W x S2 Alloys

Abstract This study systematically modulated the healing and creation of S vacancies in monolayer Mo(1–x)WxS2 alloys via low-temperature H2 and S vapor annealing, observing three distinct types of photoluminescence (PL) evolutions. Type I featured intensified PL, a decreased X–/X...

Numerical Study on Hydrodynamic Characteristics of a Supercavitating Vehicle During Booster Separation

The application of a staged booster system can significantly extend the operational range of a supercavitating vehicle. Booster separation from the main body within the supercavity, followed by its downstream movement and exit from the cavity, constitutes a key process in the rea...

A Review of Ship Path Planning for Autonomous Navigation: From Model-Driven Methods to Deep Reinforcement Learning

Ship path planning is a central challenge in autonomous navigation for unmanned surface vehicles and maritime autonomous surface ships. It is not simply a shortest-path problem, but a constrained sequential decision process that must reconcile collision risk, route efficiency, CO...

MambaUNet: An Efficient U-Shaped State-Space Network for Underwater Image Enhancement

Underwater images are frequently degraded by wavelength-dependent absorption and scattering, resulting in color casts, low contrast, blurred textures, and loss of structural details. Existing enhancement networks may struggle to balance global context modeling, local detail recov...

Wintertime organic carbon export provides a potential food source for zooplankton in the High Arctic

Abstract Pulsed particulate organic carbon export plays a vital role in sustaining Arctic marine ecosystems and the biological pump. Wintertime particulate organic carbon export in ice-covered Arctic waters is generally considered negligible due to light-limited local primary pro...

Optimizing one-dimensional bin packing for conveyor belt logistics via pointer-network-based A2C and heuristics

The one-dimensional Bin Packing Problem (1D-BPP) poses significant challenges in logistics, particularly for optimizing item packing sequences in warehouse conveyor belt systems. This paper proposes a Deep Reinforcement Learning (DRL) approach using Advantage Actor-Critic (A2C) i...

Study on Microstructure and Wear Resistance Service Characteristics of AlCrN-Coated Relay Injection Mold

To address the problem of the short service life of relay injection molds caused by erosion of high-temperature glass fibers, AlCrN coatings were deposited on the surface of ELMAX mold steel using multi-arc ion plating technology. The surface morphology, cross-sectional morpholog...

Artificial intelligence driven personalized adaptive training system for individual differences in competitive sports

The current competitive sports training system generally neglects individual differences, leading to significant inter-individual variations in training effects. To address this issue, this study developed an AI-based personalized adaptive training scheme system. A 12-week interv...

Mirror‑Induced Field Compression Drives Tunable Strong Exciton–Plasmon Polaritons in WS 2 /h‐BN/Au Heterostructures

ABSTRACT Deep‑subwavelength confinement and strong coupling at visible frequencies are central to scalable nanophotonic and quantum technologies. While transition metal dichalcogenides are promising candidates for such confinement, achieving tunable strong coupling often relies o...
