Pelvic fractures are rare but severe injuries that severely affect patients’quality of life.Treatment of these fractures often involves invasive approaches with high risk of injuries to nervous structures,particularly lumbosacral plexus.The introduction of minimally invasive surgical approaches,such as the lateral rectus approach,not only contributes to preserving lumbar plexus integrity in operated patients but also positively impacts their psychological well-being.Patients treated by surgical reduction of pelvic fractures with lumbosacral plexus injury often experience states of anxiety and depression.The lateral rectus approach is associated with lower levels of anxiety and depression compared to more invasive surgical techniques used for similar fractures. 展开更多

A structured method to generate conformal finite element(FE)mesh for realistic 3D woven textile reinforced composite is proposed.It is based on a voxel structure mesh reconstruction framework and aims to provide accurate composite model at yarn level with material properties ready for use in commercial FE software.The textile representative volume element(RVE)is generated at filament level implementing the digital element method.Yarn structure is determined by filament bundle with variant cross-section shapes along its path.Yarn surface is then extracted using the Delaunay triangulation algorithm and a surface mesh is initiated.Then,the mesh domain is defined and constructed by voxel structure.Periodic boundary conditions,inter-yarn,and yarnmatrix interfaces are eliminated by re-mesh and mesh optimization.An element splitting rule is established to split the voxel unit into sub-elements to create smooth interface.A 3D orthogonal weave fabric reinforced composite is generated and simulated under compressive load.The composite structure and damage morphology are in good agreement with those of the experiment. 展开更多

We propose an eigen microstate approach(EMA)for analyzing quantum phase transitions in quantum many-body systems,introducing a novel framework that does not require prior knowledge of an order parameter.Using the transversefield Ising model(TFIM)as a case study,we demonstrate the effectiveness of EMA by identifying key features of the phase transition through the scaling behavior of eigenvalues and the structure of associated eigen microstates.Our results reveal substantial changes in the ground state of the TFIM as it undergoes a phase transition,as reflected in the behavior of specific componentsξ_(i)^((k))within the eigen microstates.This method is expected to be applicable to other quantum systems where predefining an order parameter is challenging. 展开更多

In this paper,the N-soliton solutions for the massive Thirring model(MTM)in laboratory coordinates are analyzed via the Riemann-Hilbert(RH)approach.The direct scattering including the analyticity,symmetries,and asymptotic behaviors of the Jost solutions as|λ|→∞andλ→0 are given.Considering that the scattering coefficients have simple zeros,the matrix RH problem,reconstruction formulas and corresponding trace formulas are also derived.Further,the N-soliton solutions in the reflectionless case are obtained explicitly in the form of determinants.The propagation characteristics of one-soliton solutions and interaction properties of two-soliton solutions are discussed.In particular,the asymptotic expressions of two-soliton solutions as|t|→∞are obtained,which show that the velocities and amplitudes of the asymptotic solitons do not change before and after interaction except the position shifts.In addition,three types of bounded states for two-soliton solutions are presented with certain parametric conditions. 展开更多

Shale gas, as a clean, low-carbon, and abundant unconventional natural gas resource, plays a crucial role in achieving clean energy transformation and carbon neutrality. The Fuling shale gas reservoir in Sichuan Basin stands out as China's most promising area for shale gas exploration and recovery. However, the continuous recovery of shale gas in the southern Sichuan Basin has led to well interference events in hundreds of wells, with the furthest well distance reaching over 2000 m. This study introduces a multi-scale approach for transient analysis of a multi-well horizontal pad with well interference in shale gas reservoirs. The approach utilizes Laplace transform technology, boundary element theory, and the finite difference method to address the complexities of the system. Well interference is managed using the pressure superposition principle. To validate the proposed multi-scale method, a commercial numerical simulator is employed. The comprehensive pressure behavior of a multi-well horizontal pad in a shale gas reservoir is analyzed, encompassing wellbore storage effect, skin effect, bilinear flow, linear flow, pseudo-radial flow of primary fractures, well interference period, dual-porosity flow, pseudo-radial flow of the total system, and boundary-dominated flow. A case study is conducted on the typical well, the well with the longest production history in the Fuling shale gas reservoir. The rate transient analysis is conducted to integrate up to 229 days of shale gas production daily data and wellhead pressure data, enabling the generation of pressure behavior under unit flow rate. The results indicate that the linear flow, transitional flow, and boundary-dominated flow are more likely to be observed in the actual data. Secondary fractures are considered to be the primary pathways for fluid migration during well interference events. The evaluated formation permeability is 2.58 × 10^(-2) mD, the well spacing is 227.8 m, the diffusion coefficient is 1.49 × 10^(-4), and the skin factor is 0.09. 展开更多

The relationship between the neighborhood environment and well-being is attracting increasingly attention from researchers and policymakers,as the goal of development has shift from economy to well-being.However,existing literature predominantly adopts the utilitarian approach,understanding well-being as people’s feelings about their lives and viewing the neighborhood environment as resources that benefit well-being.The Capability Approach,a novel approach that conceptualize well-being as the freedoms to do or to be and regard environment as conversion factors that influence well-being,can offer new lens by incorporating human development in-to these topics.This paper proposes an alternative theoretical framework:well-being is conceptualized and measured by capability;neighborhood environment affects well-being by providing spatial services,functioning as environmental conversion factors,and serving as social conversion factors.We conducted a case study of Changshu City located in eastern China,utilizing multiple resource data,applying explainable artificial intelligence(XAI),namely eXtreme Gradient Boosting(XGBoost)and SHapley Additive exPlana-tions(SHAP).Our findings highlight the significance of viewing the neighborhood environment as a set of conversion factors,as it provides more explanatory power than providing spatial services.Compared to conventional research based on linear relationship as-sumption,our results demonstrate that the effects of neighborhood environment on well-being are non-linear,characterized by threshold effects and interaction effects.These insights are crucial for informing urban planning and public policy.This research enriches our un-derstanding of well-being,neighborhood environment,and their relationship as well as provides empirical evidence for the core concept of conversion factors in the capability approach. 展开更多

BACKGROUND Median sternotomy has been considered the gold standard approach for anterior mediastinal tumor resection.However,recent advances in video-assisted thoracoscopic surgery and robotic-assisted thoracoscopic surgery with carbon dioxide insufflation have allowed minimally invasive approaches even for large and locally invasive tumors of the upper-anterior mediastinum.The subxiphoid robotic optical approach is a recently developed technique for accessing the mediastinum.The trans-subxiphoid technique offers excellent exposure of the surgical field,reduces postoperative pain,facilitates specimen retrieval even for large tumors,and potentially improves early surgical outcomes.AIM To evaluate the safety,feasibility,and outcomes of a robotic subxiphoid approach for the resecting of large/invasive mediastinal tumors.METHODS Between July 2024 and September 2025,12 patients underwent subxiphoid robotic mediastinal resection.The diameter of the operated lesions ranged from 30 mm to 70 mm.A 3 cm subxiphoid incision was made at the subxiphoid level for GelPort placement,allowing for optical port access.Two operating ports were placed at the sixth intercostal space bilaterally.Carbon dioxide insufflations(8-10 mmHg)enlarged the surgical field,improving visualization of critical anatomical landmarks,such as the internal mammary arteries and phrenic nerves.This approach allowed complete resection of large or invasive tumors,preserving thoracic stability and reducing the risk of postoperative myasthenic crisis.RESULTS The mean operating time was 170.2 minutes,and the median hospital stay was 3.5 days.No major postoperative complications occurred.Two conversions were necessary:One with a lateral robotic approach due to previous abdominal surgery,and one with a sternotomy for tumor invasion of the aortic arch.Histopathological analysis identified nine thymomas and one solitary fibrous tumor.CONCLUSION Subxiphoid robotic approach is a safe,effective technique for extended thymectomy,fulfilling both oncological and myasthenia gravis surgical objectives. 展开更多

Labor provisions have become a fundamental trade rule in regional and bilateral trade agreements.Although China’s legislation on pilot Free Trade Zones includes content related to labor protection,it primarily aligns with labor indicators in“Doing Business”,the assessment of business situations issued by the World Bank.It differs from the labor rights protection focus emphasized in trade agreements.The latest strategic documents issued by the State Council of China have addressed this issue to fully achieve the goal of aligning Free Trade Zones with high-standard trade agreements.Building on the development of Free Trade Zone legislation and domestic labor law governance,China should proactively explore a tailored approach to labor provisions in Free Trade Agreements.In this approach,it should explicitly define the“baseline”and“ceiling”for labor provisions during negotiations and,within this framework,establish benchmarks for labor rights protection,enforcement mechanisms,and cross-border regulatory mechanisms suited to the specific conditions of the agreement parties. 展开更多

The U.S.Food and Drug Administration(FDA)'s program documents regarding the animal-free approach for the efficacy,pharmacokinetics,and safety evaluation of new drug preclinical studies have been rolled out gradually.This process has taken the FDA seven years.Starting from the reduction of funding for animal of data from organ-on-a-chip solely for pharmacodynamic studies[[1],[2],[3]],to the explicit proposal of the animal-free approach for pharmacodynamic studies in the FDA Modernization Act in Reference[4],and to the indication in 2025 that safety studies should also prioritize safety research data from in vitro microphysiological systems[5],this demonstrates the FDAs determination to gradually achieve the animal-free approach and also signals a profound paradigm shift in the field of drug research and development.This policy direction not only addresses the requirements of ethics and technological advancement but may also reshape the entire new drug development industrial chain. 展开更多

Human rights education in primary and secondary schools is the initial and crucial phase of human rights education.Based on the normative documents formulated by the United Nations for human rights education during this phase,this paper constructs the United Nations standards for human rights education in primary and secondary schools,which include four major aspects:educational content,educational methods,reference mechanisms,and human rights concepts.They correspond respectively to the core connotations,practical pathways,institutional protections,and spiritual pursuits of human rights education in primary and secondary schools.On the basis of critically reflecting on these standards,and in reference to the United Nations standards and in accordance with China’s actual conditions,this paper proposes the“Chinese Approach”for human rights education in primary and secondary schools:first,in terms of legislation,clear legal basis should be provided;second,in terms of administration,clear goals and action guidelines should be provided;third,in terms of resource guarantee,sufficient resource support should be provided;fourth,in terms of curriculum design,it should be suitable for Chinese primary and secondary school students;fifth,in terms of evaluation mechanism,a variety of evaluation mechanisms should be constructed. 展开更多

Renewable energy sources(RES)have strong uncertainties,which significantly increase the risks of power imbalance and load shedding in composite power systems.It is thus necessary to evaluate the operational reliability for guiding economic dispatch and reducing the risks.Current methods cannot meet the requirement for the operational timeliness of reliability evaluations due to the high computa-tional complexity of the optimal power flow(OPF)calculations of massive contingencies.This paper pro-poses a fully analytical approach to construct fast-to-run analytical functions of reliability indices and avoid reassessments when the load and RES change.The approach consists of uniform design(UD)-based contingency screening and a modified stochastic response surface method(mSRSM).The contin-gency screening method is used to select critical contingencies while considering the uncertainties.The mSRSM is used to construct the analytical functions of the load shedding to the load and RES gener-ation for the selected contingencies.An analytical function of a smooth virtual variable that maps to the load shedding is established in such a way that,when the load and RES vary,the reliability can be assessed within a very short time rather than using laborious OPF calculations.Case studies illustrate the excellent performance of the proposed method for real-time reliability evaluation. 展开更多

In this paper,the isogeometric analysis(IGA)method is employed to analyze the oscillation characteristics of functionally graded triply periodic minimal surface(FG-TPMS)curved-doubly shells integrated with magneto-electric surface layers(referred to as"FG-TPMS-MEE curved-doubly shells")subjected to low-velocity impact loads.This study presents low-velocity impact load model based on a single springmass(S-M)approach.The FG-TPMS-MEE curved-doubly shells are covered with two magneto-electric surface layers,while the core layer consists of three types:I-graph and Wrapped Package-graph(IWP),Gyroid(G),and Primitive(P),with various graded functions.These types are notable for their exceptional stiffness-to-weight ratios,enabling a wide range of potential applications.The Maxwell equations and electromagnetic boundary conditions are applied to compute the change in electric potentials and magnetic potentials.The equilibrium equations of the shell are derived from a refined higher-order shear deformation theory(HSDT),and the transient responses of the FG-TPMS-MEE curveddoubly shells are subsequently determined using Newmark's direct integration method.These results have applications in structural vibration control and the analysis of structures subjected to impact or explosive loads.Furthermore,this study provides a theoretical prediction of the low-velocity impact load and magneto-electric-elastic effects on the free vibration and transient response of FG-TPMS-MEE curved-doubly shells. 展开更多
