This study proposes a reinforcement learning-based position-based impedance control (RLPIC) method for robotic braces to enable active human–robot interaction. To safely simulate and train the control system, a novel five-dimensional, three-layer digital twin (DT) model is developed, integrating physical modeling, digital modeling, bidirectional interaction, and optimization, enhanced by a neural network-based parameter estimator. Both numerical simulations and real-time experiments validate the DT and RLPIC framework, demonstrating improved tracking and interaction performance in AIS treatment.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":60486,"journal":{"name":"国际机械系统动力学学报(英文)","volume":"5 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/msd2.70050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce SFR, a biomimetic surface was developed through a collaborative multi-process strategy involving a combination of laser ablation and spraying techniques. Initially, biomimetic fish scale (BFS) arrays with five different spacing (<i>s</i>) values were fabricated on an aluminium (Al) substrate using laser ablation, which was then replicated with polydimethylsiloxane (PDMS). Subsequently, a mixture of superhydrophobic nanoscale SiO₂ particles (SH-SiO₂), PDMS and n-hexane solution was uniformly sprayed onto the BFS surface to enhance its hydrophobic properties. The morphology of these biomimetic surfaces was characterised using a scanning electron microscope (SEM) and ultra-depth field microscope. The drag reduction (<i>DR</i>) performance of the biomimetic surfaces was evaluated within a Reynolds (<i>Re</i>) number range of 4.2 × 10⁴–2.2 × 10⁵ in a circulating water tunnel. The results indicated that a drag reduction rate of 11.82% was achieved with the modified BFS at <i>s</i> = 300 μm and <i>Re</i> = 1.7 × 10⁵. Additionally, the drag reduction mechanism of the modified BFS surface was analysed using the computational fluid dynamics (CFD) method. The excellent drag reduction performance was attributed to the combined effects of the ‘rolling bearing’ caused by streamwise vortices, high-low velocity streaks and the velocity slip effect caused by hydrophobic properties at the interface. These findings offer a novel approach for creating multi-effect coupled drag reduction surfaces.</p>","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, this study investigates the performance and microstructural evolution of silver-based printed circuits under electromechanical coupling loads and unveils the underlying material degradation mechanisms. Resistance change curves reveal that, under identical bending loads, lower current density (208.3 A/cm²) accelerates circuit degradation more significantly than higher current density (1164.7 A/cm²). By analysing the thermal characteristics, conductive phase structure, and conductive network of printed circuits under mechanical loading, electric field stimulation, and electromechanical coupling, it is evident that heat plays a critical role in determining resistance changes in silver-based printed circuits. At lower temperatures, heat-induced oxidation of nanosilver to nonconductive silver oxide emerges as the primary driver of resistance increase. Conversely, at higher temperatures, heat-induced sintering of silver forms new conductive pathways that offset the resistance increase caused by the oxidation of silver nanoparticles.

Acellular materials derived from animals offer a promising solution to this issue. In the present investigation, an acellular scaffold is prepared from yellowfin tuna skin (<i>Thunnus albacares</i>) for skin regeneration application by comparing the efficacy of three chemical decellularization agents: sodium hydroxide (NaOH), Triton X-100 (TT), and sodium dodecyl sulfate (SDS). The impact of these agents on the resulting acellular dermal matrices was evaluated by assessing collagen preservation, DNA removal, residual fat and ash content, and structural integrity using hydroxyproline assay and chemical composition analysis. Mechanical properties, swelling behavior, degradation rate, water vapor transmission rate, moisture loss, and biocompatibility of the acellular membrane were also characterized. Furthermore, the regenerative potential of these samples was assessed in a porcine full-thickness skin defect model. The results demonstrated that all three decellularization methods effectively removed cellular components, with varying degrees of collagen preservation and ECM structural alteration. TT treatment yielded the highest collagen retention and a relatively intact fibrous structure, while NaOH caused significant structural damage. Mechanical testing revealed that hydration significantly improved the elasticity of TT- and SDS-treated samples. In vitro biocompatibility assays showed no significant cytotoxicity or hemolysis. These findings suggest that the acellular membrane holds promise as a biomaterial for skin regeneration applications due to its effective decellularization, preserved collagen structure, and favorable biocompatibility.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00218-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest levels of polybrominated diphenyl ethers (PBDEs) and PBDD/Fs in pooled eggs from free-range chickens were detected at sites where e-waste was burned, near waste incineration, metallurgical facilities and at landfills/dumps. The PBDD/F pattern indicated that PBDEs and Tetrabromobisphenol A (TBBPA) are the major sources for PBDD/F contamination in the eggs. Dioxin bio-assays like the DR CALUX are useful to screen for total dioxin toxicity (PCDD/Fs, dl-PCB, PBDD/Fs and mixed polybrominated-polychlorinated dibenzo-p-dioxins/furans (PXDD/Fs)). The robust and cheap bioassay approach is currently the only method which also quantifies the dioxin-like toxicity of the complex group of PXDD/Fs where instrumental analysis cannot quantify the dioxin toxicity.&lt;/div&gt;&lt;div&gt;A major source of human exposure to BFRs is eggs from chickens that have pecked particles from e-waste plastics or other waste/products treated with BFRs. When chickens ingest plastic particles containing contaminants, the latter are transferred to their eggs. This is similar to what has been documented for sea birds. The BFRs listed as persistent organic pollutants (POP) with the highest level detected were PBDEs and hexabromocyclododecane (HBCDD). HBCDD is mainly contained in expanded and extruded polystyrene (EPS/XPS) which can be easily pecked by chickens. This was likely the reason for several HBCDD contaminated eggs above 1000 ng/g fat and up to 18,321 ng/g fat. EPS/XPS insulation which contain 90 % of all HBCDD formerly produced (∼640,000 tonnes in ∼42 million tonnes of EPS/XPS) is partly also used as insulation in henhouses and other parts of farms and private houses. Since chickens like to peck at and eat the soft polymer, this can be a relevant exposure source. A wide range of novel BFRs (nBFR) were detected in chicken eggs. The nBFR with the highest levels and frequency detected was 1,2-Bis(2,4,6-tribromophenoxy)ethane (BTBPE). BTBPE was often found in eggs in the monitoring of the International Pollutants Elimination Network (IPEN) with levels frequently above 10 ng/kg fat and three samples above 100 ng/g fat, up to 221 ng/g fat. DBDPE was also frequently detected in eggs with a maximum concentration of 2077 ng/g fat at the sites where plastic waste is used as fuel in boilers/incinerators.

Using panel data from 236 prefecture-level cities in China during the period 2006-2019， this study employed a directional distance function parameter estimation method to measure the marginal carbon dioxide reduction costs in cities in China. Building on this result， the study analyzed the temporal and spatial evolution， classification， inequality， and spatial convergence characteristics of these marginal reduction costs using models such as kernel density functions， the Dagum Gini coefficient， and spatial convergence. The key findings are as follows： ①From 2006 to 2019， China's marginal carbon reduction cost （measured in CO₂e） showed a trend of first declining and then rising. The average value first decreased from 7.45 thousand yuan per ton to 5.58 thousand yuan per ton and then increased to 20.36 thousand yuan per ton. ②The curve of China's marginal carbon reduction cost showed a U-shaped trend over the period 2006-2019， with the majority of cities positioned to the left of the lowest point. ③The inequality in China's marginal carbon reduction costs followed a pattern of initial increase followed by decrease. The overall Gini coefficient declined from 0.220 in 2006 to 0.151 in 2019. ④From 2006 to 2019， China's city-level marginal reduction costs demonstrated <i>σ</i>-convergence characteristics and supported the <i>β</i>-spatial convergence mechanism. There was significant heterogeneity in reduction costs across different economic regions， and the classification of city-level marginal reduction costs showed a trend toward polarization. Although China has achieved some results in carbon reduction， the task difficulty and cost have gradually increased as carbon reduction action has increased. Therefore， to facilitate the coordinated reduction of carbon reduction costs across cities in China， the government should establish inter-city collaborative mechanisms for emissions reduction， promote the coordinated development of green and low-carbon industries among cities， enhance the collaborative application of energy efficiency and energy-saving technologies across urban areas， deepen the collaborative advancement of environmental education and public participation， and innovate the design of inter-city financing models and incentive mechanisms.
