Usually,the disposal of the emergency is organized as a cross-organization emergency response process(CERP),where various resources are involved.The lack of these resources may cause resource conflicts that can delay or even suspend the CERP,thereby increasing the risk imposed on life,property,and the environment.In this paper,we propose a novel approach to construct conflict-free and efficient CERPs.This approach first presents a branching place-based method to decompose a CERP into a set of execution paths.In essence,an execution path refers to a process fragment without choice structures corresponding to some kind of process instance in the CERP.In practice,each execution of the CERP can only follow such an execution path.Next,it determines whether each execution path contains resource conflicts.If not,then the execution path is considered conflict-free;otherwise,it will be resolved using a delay-based strategy.Lastly,it introduces an execution path-oriented strategy to merge all originally conflict-free and resolved execution paths to form a resolved CERP,in which each execution of it is conflict-free and efficient.The proposed approach is implemented in the tool RCTool,and a group of experiments conducted on actual CERPs demonstrates that it is more effective in constructing conflict-free and efficient CERPs compared to existing proposals,and its computation overhead is also acceptable in practice. 展开更多

Tunnel engineering faces significant challenges due to the complexity and variability of geological conditions.In such contexts,the timely and appropriate adjustment of shield construction parameters(SCP)to match current geological conditions is crucial for ensuring safe and efficient construction.This paper proposes a self-adaptive intelligent decision-making method for risk control in shield tunnel construction,which integrates a multilayer perceptron(MLP)with a multi-objective optimization(MOO)algorithm.Specifically,an MLP combined with particle swarm optimization(PSO)is employed to predict the optimal SCP.These predicted parameters,along with stratum mechanical properties and tunnel depth,serve as inputs for forecasting two critical performance indicators:maximum surface settlement(MSS)and driving speed(DS).The predictive model,coupled with the MOO algorithm,is then utilized to enable dynamic feedback control of the SCP during construction.To demonstrate the applicability of the proposed method,a case study of Qingdao Metro Line 6 is presented.The results indicated that based on the proposed PSO-MLP-non-dominated sorting genetic algorithm II(NSGA-II),both MSS and DS are effectively improved.The adaptive decision-making between SCP and geological conditions can be realized. 展开更多

The tissues spanning from tendon to bone exhibit a highly specialized extracellular matrix(ECM)architecture,characterized by hierarchical collagen alignment and a gradient mineral composition,which together enable efficient force transfer and guide spatially organized cellular phenotypes.However,recapitulating such complex multi-scale organization and compositional gradients to achieve integrated soft-hard tissue remains challenging.Here,we report the de novo construction of biomimetic collagen-mineral matrices that mimic both the hierar-chical organization and mineral gradient distribution of the native tendon-to-bone ECM.Through synergistic electro-assembly and post-treatment,collagen molecules self-organized into aligned fibrillar matrices with multi-scale architecture,replicating tendon-side morphology while providing robust tensile mechanics.At the opposing end,intrafibrillar and interfibrillar minerals were spatially patterned to emulate the mineral gradient from tendon to bone.This structural and compositional continuum enables smooth mechanical transition across the soft-hard tissue interface and promotes region-specific regeneration of aligned tendon-like tissue,fibrocartilage and bone.In vivo studies in rabbit models confirm that these de novo constructed matrices support histological reconstruction of multiple tissues from tendon to bone at the rotator cuff,and significantly improve functional recovery.This work presents a bottom-up biomimetic strategy for engineering multiscale collagen-based scaf-folds and demonstrates the therapeutic potential of de novo constructed matrices for multiple tissue regeneration. 展开更多

Action errors-unintentional deviations from goals,rules,or standards-are an inevitable part of work in construction.Understanding how individuals and organizations can embrace and"learn through errors"(i.e.,how to handle them effectively)is crucial for contributing to project success.However,within construction,a prevailing belief persists that errors can and should be eliminated,fostering a zero-tolerance mindset.Organizations that adopt this mindset risk stifling their capacity to learn,innovate,and improve profitability.While errors can indeed have negative consequences,they also play a vital role in enabling learning and innovation.Given the limited empirical research on action errors in construction,this paper aims to stimulate inquiry into this promising area of study.It briefly outlines different forms of error orientation and proposes directions for future research relevant to construction organizations.The contributions of this paper are twofold,as it:①advocates for construction organizations to broaden their understanding of errors to enhance their learning capability and②identifies ways in which organizations can improve their capacity to learn and innovate through error management. 展开更多

Oil-fired construction machinery(OCM)is a major source of urban air pollutants and CO2 emissions,and elec-trification is a crucial pathway for improving air quality and achieving China’s dual carbon goals;however,its feasibility has not been fully explored.This study uses data envelopment analysis and the analytic hierarchy process to establish a development potential index,covering technical efficiency,economic cost,application sce-narios,and charging time and range,with an empirical analysis conducted in Beijing.The findings indicated the high feasibility of replacing OCM with electric alternatives,especially within the low-power range.Based on 2023 registered coding dat1,it is projected that by 2030,electrification could reduce regional average con-centrations of CO,NOx,PM2.5 and VOCs by 12.2%to 56.4%and reduce CO2 by 11.7%to 56.9%.Owing to economic considerations,small-and medium-sized machinery are particularly feasible for electrification.Key recommendations include prioritizing the electrification of forklifts,lifting platforms,and small-sized machinery in high-emission areas,particularly in central urban districts.Policies such as carbon taxes,carbon markets,and performance grading systems are suggested to incentivize electrification,along with expanding high-emission restriction zones and improving energy infrastructure to support widespread electrification. 展开更多

In the construction and renovation processes of underground spaces in dense urban environments,there is an increasing demand for space-intensive layouts and special-shaped cross-sections.To address the requirements for special-shaped cross-section design and lightweight structures,this study,against the backdrop of construction of underground road ramp junctions,proposes a servo structural agent for special-shaped cross-sections and its underground excavation method with no foundation pit construction by integrating traditional underground structures with intelligent perception and servo strut control.This agent embeds servo components into the structural system and performs active force control through sensing of stress and deformation.Compared with traditional structures,servo structural agent can adaptively balance the load changes induced by excavation,thereby reducing component size and deformation.On this basis,an undercutting construction method and process are proposed,utilizing dual shield tunneling parallel construction and underground excavation to replace the traditional large working shaft schemes.Through numerical simulations of typical conditions,the servo structural agent is shown to reduce maximum deformation by 30%and peak internal forces by 10%.The related work provides novel approaches for underground excavation construction and safety control in urban areas with dense underground road networks. 展开更多

Bio-carbonation of reactive MgO has been regarded as a promising and eco-friendly method for construction and demolition waste(CDW)cementation in various geotechnical engineering applications.However,the beneficial effect of bio-carbonation of reactive MgO cemented CDW(BCM-samples)can be altered when exposed to wetting-drying cycles induced by extreme climate changes or groundwater fluctuations.To better understand the durability of BCM-samples and their underlying deterioration mechanisms,a series of BCM-samples was prepared to investigate their physical-mechanical performance and microstructure evolution subjected to the wetting-drying cycles.The results indicated that the wetting-drying cycles can deteriorate the BCM-samples,and their physical-mechanical behaviors change quickly at the cycle beginning and then smoothly after 2 cycles.With the increase in cycling,the apparent deterioration with efflorescence and microcrack development can be observed.The mass loss and water absorption rates increased while the dry density,compressional wave velocity,and unconfined compression strength decreased.Urea pre-hydrolysis treatment can significantly improve the durability of BCM-samples,as the more hydrated magnesia carbonates(HMCs)enhance the cementing effects.After 10 cycles,the UCS of pre-hydrolyzed samples decreased 25.4%to 4.45 MPa,while that of ordinary samples decreased 50.7%to 1.20 MPa.The deterioration of BCM-samples caused by wetting-drying cycles can be attributed to two factors.One of the main factors is the structural integrity changes caused by the rapid loss of soluble material at the initial cycling stages.Another factor is the decrease in cementation induced by the loss of brucite and HMCs at the following cycle stages. 展开更多

As international construction projects continue to expand,construction enterprises are accumulating vast amounts of contract‑related text data,making the effective management and extraction of knowledge from these dense texts essential to mitigate knowledge loss and ensure efficient contract management.The advent of large language models(LLMs)presents a promising avenue for enhancing contract knowledge management through intelligent systems.However,challenges such as hallucination,inflexibility,and lack of interpretability often diminish practitioners’confidence in applying these models to real‑world scenarios.This study seeks to develop a knowledge‑based question‑and‑answer(Q&A)system for international construction contracts by integrating both the knowledge graph(KG)and the LLM.Built upon a domain‑specific KG derived from the 2022 edition of the Fédération Internationale des Ingénieurs‑Conseils(FIDIC)Yellow Book and the NEC4 Conditions of Contract,the system leverages LLM to conduct synergistic reasoning with the KG,enabling it to answer complex queries using both tacit knowledge and external sources.Experimental results demonstrate that the proposed approach markedly enhances the model’s performance in Q&A tasks of contract knowledge,achieving an average success rate exceeding 87%in terms of both accuracy and interpretability.This model provides a specialized Q&A system for international construction enterprises,facilitating flexible knowledge acquisition and task‑oriented analysis in contract management,while also introducing a novel framework for integrating AI technologies into the management of international construction contracts. 展开更多

Phenomenological methodologies are fruitful to illuminate the meaning of human experiences but are rarely applied in construction research.These methodologies could reveal insights into the tacit and contextual dimensions of construction practice that are often overlooked by more traditional,quantitative approaches.Learning from practitioners'experiences is particularly appropriate for construction,where much expertise is embedded in everyday practice rather than explicit documentation.It is therefore argued that construction research can benefit from methodologies that attempt to more fully appreciate practitioners'experiences.As the lived experiences of construction professionals remain understudied,there is surprisingly little guidance for selecting any appropriate phenomenological methodology to tackle questions of concern.The objective of this paper is to offer such methodological guidance.Three phenomenological methodologies are discussed,and guidelines are provided for helping to select and apply one of them. 展开更多

The shale gas development in China faces challenges such as complex reservoir conditions and high development costs.Based on the pore pressure and geostress coupling theory,this paper studies the geostress evolution laws and fracture network characteristics of shale gas infill wells.A mechanism model of CN platform logging data and geomechanical parameters is established to simulate the influence of parent well’s production on the geostress in the infill well area.It is suggested that with the increase of production time,normal fault stress state and horizontal stress deflection will occur.The smaller the parent well spacing and the longer the production time,the earlier the normal fault stress state appears and the larger the range.Based on the model,the fracture network morphology and construction parameters of infill wells are optimized.parentparentparentparent The results indicate that:1:A well spacing of 500 m achieves a Pareto optimum between“full reserve coverage”and“stress barrier”;2:A parent well recovery degree of 30%corresponds to the critical point of stress reversal,where the lateral deflection rate of the infill fracture is less than 8%and the SRV loss is minimized;3:6-cluster intensive completion with twice the liquid intensity increases the fracture complexity index by 1.7 times,enhances well group EUR by 15.4%,and reduces single-well cost by 22%.This research fills the theoretical gap in the collaborative optimization of“multi-parameter,multi-objective and multi-constraint”and provide parameter optimization basis for shale gas infill well development in China and help to improve the development efficiency and economic benefits. 展开更多

Mobile-Assisted Language Learning(MALL)has garnered substantial attention due to its demonstrated potential for significantly enhancing learner engagement and instructional effectiveness.However,current research primarily foregrounds learners’experiences,often overlooking the emotional trajectories and teachers’identity construction during its implementation.Grounded in Sociocultural Theory(SCT),this study employs a narrative approach to examine the emotional evolution and identity transformation of a university English teacher adopting MALL.Drawing on nearly four years of empirical data—including interviews,dialogues,and reflective journals—the analysis reveals that the teacher progressed through three distinct identity stages:a conservative novice,a natural user,and an enthusiastic adopter.Each stage aligned with an emotional transition,moving from anxiety to acceptance and,ultimately,to confidence.His internalization of MALL unfolded across three sequential phases:establishing connections,deepening learning,and engaging in critical reflection.This study underscores the dynamic interplay between emotion and identity and posits that effective technology integration must attend to teachers’emotional support needs.The findings may offer valuable insights for the professional development of university English teachers and for the strategic integration of educational technology. 展开更多

This study investigated the impact of the xu-argument-based continuation on Chinese high school students’English syntactic complexity captured using verb-argument constructions(VACs)over an 8-week period.Participants were two comparable groups of students:one group worked with English input texts(i.e.,E-E),while the other worked with Chinese input texts with the same content(i.e.,C-E).The results showed that over time,the E-E group exhibited a greater tendency to use a wider range of VACs,such as caused-motion constructions,attributives,passives,and phrasal verbs.At the same time,they reduced their use of simpler VACs like intransitive-motion and simple transitive constructions,especially when compared to the C-E group.This pattern was also evident in the topic-based writing during the posttest.These findings strongly support the effectiveness of xu-argument-based continuation tasks in promoting the development of L2 VAC knowledge.They suggest that tasks combining language input with output can significantly enhance learners’ability to use more sophisticated VACs. 展开更多

The efficient transfer of tacit knowledge is crucial for enhancing teamwork resilience and promoting collaborative innovation in construction projects.This study used functional near-infrared spectroscopy(fNIRS)hyperscanning technology to measure interpersonal brain synchronization(IBS)during the transfer of different classifications of tacit knowledge.This study explored the relationships among types of tacit knowledge,IBS during the transfer process,and the performance of tacit knowledge transfer.Finally,the role of knowledge behavioral characteristics in the process of tacit knowledge transfer was revealed.The results show that i)there is a significant IBS between the sender and receiver during the transfer task,with the IBS level of the cognitive tacit knowledge group being significantly lower than that of the technical tacit knowledge group.ii)There is a significant causal relationship between the IBS level of the transferring subjects and transfer performance,and the type of tacit knowledge influences transfer performance through IBS.iii)The tacit knowledge learning willingness of the receiver and the tacit knowledge sharing willingness of the sender moderate the relationship between the classification of tacit knowledge and the IBS level,and the absorptive capacity of the receiver moderates the relationship between the IBS level and tacit knowledge transfer performance.This study identifies the transfer mechanism of engineering tacit knowledge and provides a reliable predictor for the performance of tacit knowledge transfer with strong hysteresis. 展开更多

Based on the post-frac core evaluation results for shale gas reservoirs in the Jiaoshiba block of the Fuling gas field,a simulation method for tensile-shear composite fracture networks in shale and a multi-scale characterization method for residual gas were developed.The types and distribution characteristics of residual shale gas were clarified,and an efficient seepage field with coordinated"artificial well pattern induced fracture network-natural fracture network"was established.Strategies for residual gas recovery were proposed,and the expected technologies for efficient development of shale gas reservoirs were recommended.The induced fractures in shale exhibit features such as single overall morphology,clustered non-uniform distribution,branching dendritic extension and limited propped area.Residual gas can be classified into four types:gas uncontrolled by well pattern,gas insufficiently swept by inter-well fractures,gas unevenly swept by inter-layer fractures,and gas unswept between clusters.For purpose of residual gas recovery and enhanced gas recovery,an efficient seepage field with coordinated"artificial well pattern-induced fracture network natural fracture network"can be constructed through drilling infill wells with small well-spacing,sidetracking in old wells,differential trajectory design,and precise fracturing design.Future efficient development of shale gas is expected to be achieved by improving accurate reservoir characterization,advancing coordinated 3D development technologies,iteratively optimizing technologies for enhanced shale gas recovery,and deepening the synergy between conventional and unconventional development methods.These efforts are believed to drive high-quality advancement of the shale gas development technology in China. 展开更多

Fluorinated motifs are prevalent in both pharmaceuticals and agrochemicals.The incorporation of fluorine-containing moieties to drug candidates has emerged as a potent strategy for lead optimization in pharmaceutical research and development.While extensive research has been devoted to constructing molecules that incorporate a trifluoromethylthio(SCF3−)group on a stereogenic carbon,the synthesis of trifluoromethylthiolated alkanes featuring a SCF3-substituted stereogenic carbon at non-activated site remains understudied.Herein,we report a Cu-catalyzed regio-and enantioselective hydroallylation of 1-trifluoromethylthiolated alkenes.Important to the process is the regio-and enantioselective Cu-H insertion to SCF3-substituted alkene to form chiralα-SCF3 alkyl copper intermediates,outcompeting unproductive insertion to the coupling partner,and eventually proceed to afford optically active homoallylic trifluoromethylthiolated products. 展开更多

China's rapid urbanization has driven extensive construction activities,leading to the widespread deployment of fuel-powered construction machinery and substantial greenhouse gas(GHG)emissions.We combined surveys on machinery units,operational hours,and load factors to quantify GHG emissions(CO2,CH4,and N2O)from construction machinery in China from 2013 to 2022.Emissions projections were modeled using the low emissions analysis platform(LEAP)under baseline,market-driven,policy-guided,and regulatory-driven scenarios,with parameters including machinery stock,electrification rate,and fuel consumption per hour.The results indicate that from 2013 to 2022,the number of machinery units increased significantly,driving parallel growth in CO2 and N2O emissions,whereas CH4 emissions demonstrated consistent annual decreases because of emission intensity.CO2 equivalent(CO2 eq)emissions increased by 17% from 2013 to 2021 and then decreased by 2.6% to 7.3×107t CO2 eq in 2022,with CO2 accounting for 98%-99% of total GHG emissions and N2O and CH4 accounting for1.2% and 0.1%,respectively.The primary emission sources were China StageⅢmachinery(69%),excavators(64%),and high-power equipment(>130 kW,contributing 30%-90%).Spatially,East China accounted for 47% of national emissions in 2022,followed by Central China(18%),which is related mainly to the advanced economic development and infrastructure construction demands.The scenario analysis showed that reducing machinery numbers,enhancing electrification,and improving fuel efficiency could yield substantial mitigation benefits,with the regulatory-driven scenario achieving up to 97% GHG reduction potential. 展开更多
