Forging the Resistive Republic: Social Capital, Institutional Stability, and Civic Virtue in Pluralist Democracies

Republicans too often take for granted features not easy to bring about in the absence of social capital. Lovett and Pettit (2009) consider that it is through collective political actions that citizens shed light on acts of domination. For Pettit (2012), civic vigilance is the only guarantee that “the government will be forced to remain responsive to popular inputs”. As Kimpell (2023) mentions, one of the weak points of republican theories remains the lack of an account of norm generation. I aim to show how this could occur in a way that does not constitute itself an arbitrary interference of the government in the people’s lives. The kind of generalized reciprocity which is of utmost importance for republicanism often depends on the presence of ties that connect different socio-economic groups within communities and, “where such interactions do not naturally occur, forums for interaction can be intentionally created and designed to encourage development of social capital” (Warner 2001). More specifically, I argue that such forums for interaction could be represented by polycentric systems. Furthermore, I argue that embracing polycentricity constitutes a non-dominating way in which we could promote the “resistive community” (Pettit 2012) required by republicanism. I consider that the empirical results extensively documented in the Institutional Analysis and Development framework are an appropriate starting point for designing novel republican policies and institutions that can function alongside sufficient levels of trust.

Measuring the Digital Maturity of Organisations in the People Care Sector

This study focuses on the organisations in the people care sector (OPCs), encompassing a broad spectrum of activities ranging from essential healthcare services to various aspects of daily living support. Sustainability in OPCs encompasses multiple dimensions aimed at ensuring the long-term viability, efficiency, and effectiveness of services provided to vulnerable populations. Given the critical role of digital technologies in enhancing the operational efficiency within such organisations and their sustainability, it becomes imperative to gauge their digital maturity levels. To establish a robust framework for assessing the digital maturity of OPCs, we identified 29 factors grouped into five clusters that encapsulate various dimensions of digital readiness that directly influence the sustainability of OPCs. We employed the SNAP methodology to ascertain the relative significance of these factors and clusters. Furthermore, each factor was articulated through the lens of digital maturity using the rubrics approach, offering a nuanced understanding of the OPCs’ digital readiness across four distinct levels. Experts from the people care sector, IT, and multi-criteria decision-making contributed invaluable input during the instrument’s development phase. Theoretical validation of the instrument involved focus group discussions with domain experts, while practical validation entailed applying the instrument to real-world case studies. The instrument enables OPCs to assess their digital maturity levels, providing valuable strategic planning and decision-making insights. Furthermore, the instrument can serve as a roadmap for identifying areas ripe for digital transformation and weak points, facilitating continuous improvement and future readiness. The quantification of the digital maturity of the OPC enables the OPCs to rank at the cluster maturity level and overall maturity level. Overall, this instrument represents a significant step towards enhancing digital maturity assessment within the OPC sector, contributing to its evolution and adaptation in the digital age, and enabling the OPCs’ sustainability.

Laser welding of dissimilar TiAl/Ti6-Al-4V materials: Effects of rapid in-situ laser pre-heating on microstructure and mechanical properties of the welding joint

TiAl alloy has broad application prospects in the aerospace field. In practical working environments, connecting with other materials is considered an important means of fully utilizing their excellent properties. This study employed a laser in-situ pre-scanning method to preheat the weld seam, achieving the connection between TiAl alloy and Ti-6Al-4V. On this basis, the microstructural evolution of the fusion zone (FZ), fusion line (FL), and heat-affected zone (HAZ) of the welded joint was analyzed in detail. By comparing with traditional welding processes, the effects of laser in-situ preheating on the microstructure and properties of the welded joints were studied. The results showed that the FZ area consists of α2 and martensitic α-Ti, while the FL on the TiAl side features a transition layer of β/B2 phases, providing plasticity and toughness to the welded joint. The in-situ scanning method reduced the cracks generated during welding, resulting in a more uniform distribution of the transition layer. The obtained FZ exhibited higher microhardness. The room temperature tensile strength of the welded joint reached 650 MPa. As the temperature increased, at 400 °C, the tensile strength and elongation reached 571 MPa and 3 %, respectively, significantly higher than the 450 MPa and 1.5 % achieved by conventional welding at the same temperature. When the temperature further increased to 500 °C and 600 °C, Ti-6Al-4V experienced significant softening, becoming the weak point of the welded joint.

Analysis and optimization of the dynamic response characteristics of aircraft cargo rack

In order to effectively achieve the optimization design of the aircraft cargo rack, based on finite element modal simulation, the structure was redesigned and analyzed using two schemes of surrogate model size optimization and topology optimization, ensuring the strength requirements while improving the natural frequency and reducing the weight. According to the modal shape of vibration, additional bridge structures were added at the weak points to improve the dynamic stiffness of the structure. According to the optimization design requirements, the response surface function was constructed, and the particle swarm optimization algorithm was applied in the size optimization and surrogate model solution. A multi-objective optimization model was established for flexibility and low-order natural frequencies, and topology optimization was carried out in HyperWorks. The structural dynamic modification of the topology optimization model was performed using the modal strain energy analysis method. The research results show that both optimization methods can achieve good lightweight design. The static performance of the optimized structure is stable, and the overall modal frequency is improved.

Этногенез чувашей в трудах Н.И. Воробьева: особенности трактовки

The article examines the contribution of Professor N.I. Vorobyev to the scientific study of complex aspects of the ethnogenesis of the Chuvash people. The scientist is rightfully considered one of the prominent researchers of the problem of the origin of the Chuvash. Being one of the leaders and authors of the first volume of the collective monograph “The Chuvash. Ethnographic research. Part One” (1956), N.I. Vorobyev outlined in it his so-called "autochthonous theory" of the ethnogenesis of the Chuvash, as a people based on Finno-Ugric, but with the Turkic Bulgarian language. The article highlights the scientist's not always unambiguous views on the origin of the Chuvash, as set out by him in publications of 1930, 1950, 1953. It is noted that while many scientists at the beginning of scientific research adhered to the concept of the Finno-Ugric origin of the Chuvash, and subsequently took the position of N.I. Ashmarin, N.I. Vorobyev initially rather inclined to the Bulgarian theory, and only later became an autochthoniste. It is pointed out that one of the weak points in the scientist's interpretation of the issues of ethnogenesis was the ignoring of the factor of their Bulgarian-type language. For N.I. Vorobyev, the main basis for judgments about the origin of the Chuvash was the material and partly spiritual culture, which had a lot in common with the Mari. The article also points to the fact that the scientist did not pay attention to the factor of pagan religion in the ethnic history of the Chuvash. At the same time, it should be noted that in search of the origins of the Chuvash people, he quite widely attracted materials from famous archaeological sites of the Chuvash region. Special attention is paid in the article to the coverage of critical assessments of N.I. Vorobyev’s views by Chuvash historians V.F. Kakhovsky and V.D. Dimitriev.

Recent advancement of immunotherapy targeting lung cancer

As one of the leading cause of deaths in all types of cancer, lung cancer has attracted public attention more than decades. Many chemotherapy and physical surgery therapies have been investigated and applied to lung cancer patients to increase the overall survival rate. As a more recently emerging therapy, immunotherapy is keep advancing in recent years and has achieved great success to complement the traditional therapys weak point and even become the first line treatment against certain types of non-small cell lung cancer (NSCLC). The safety and overall survival improvement of immunotherapy drugs has been tested through multiple cycle of clinical trials, validating their potential for lung cancer treatment. Several clinical trials study the application of immunotherapy singly or in combination with chemotherapy has been established to target lung cancer many years ago. Here, this review will introduce the three most common immunotherapies against lung cancer, and both summarize their application and discuss their recent advancement based on multiple ongoing or finished clinical trials.

Modeling and failure mechanism study of unidirectional GFRP corrugated sandwich sheet piles based on discrete element method

In this paper, a DEM model of a unidirectional glass fiber reinforced polymer composite sandwich sheet pile (UGFRP-CSSP) is developed to elucidate the damage mechanisms under longitudinal bending and axial compression at the mesoscale, in order to bridge the gap between existing knowledge and its potential applications as sheet pile walls. A series of four-point bending and axial compression tests are performed on UGFRP-CSSP to validate the DEM model, which is calibrated through a sensitivity analysis of the mesoscopic parameters. The failure behavior, crack progress, and initial crack formation of the UGFRP-CSSP are investigated by correlating the results from physical experiments and numerical simulations. The research reveals that the DEM model accurately depicts the failure behavior under bending and compression of unidirectional (UD) composite elements, offering a mesoscopic perspective on the failure origins. It is identified that the tensile shear strength of the resin is the weak point leading to initial failure, as it is lower than that of the glass fibers. Longitudinal bending failure typically initiates at the skin-core interface and around the central axis of core, with cracks propagating longitudinally due to compression shear failure between fibers. Axial compression failure also occurs predominantly at the skin-core interface, with similar longitudinal cracking attributed to tensile shear failure at the acute angle fiber connections in the long span side. Finally, a new viewpoint was proposed that the fiber modulus may have a decisive impact on the failure behavior of UD composite materials.

Quasi-Hydrogen Bond and Charge-Trapping Effect Originating from Polar Side Group Lead to Significantly Suppressed Charge Transport in Polypropylene.

How to fundamentally suppress charge transport is one of the essential issues in polymer dielectrics. This work reports significant charge transport suppression by glycidyl methacrylate (GMA) side group modification on polypropylene (PP). Experimental and computational investigations discover for the first time a quasi-hydrogen bond effect generated by carbonyl and epoxide of GMA in PP inter/intramolecular structure, while introducing trap energy levels within the HOMO-LUMO gap. These energy levels suppress the leakage current of GMA-modified PP thanks to the charge-trapping effect. The quasi-hydrogen bond originating from the interaction between the high-polar GMA group and flexible PP chain raises the thermostability while averaging the electron distribution between hydrogen and acceptor oxygen, which is conducive to lessening electric weak points, suppressing charge transport, and finally enhancing the electrical breakdown strength. This work provides new thinking on polymer dielectric design and charge transport regulation utilizing electron structure and weak interaction at the molecular scale.

Structural Mastopexy: Volume Displacement in Breast Reshaping.

Although in breast reshaping, the restoration of a suitable mammary cone is the main goal of the procedure, long-lasting upper pole fullness preservation is the most common weak point of all mastopexy. Mastopexy is a challenging procedure, and a surgical procedure to create desirable long-lasting results has not been well standardized. In this paper, the authors report their experiences in structural mastopexy procedures, describing three different adipo-glandular flaps, each repositioned as auto-prosthesis to reshape upper pole contour in patients affected by a severe degree of breast ptosis. A 6-year retrospective iconographic-chart and review was performed on 89 patients undergoing mastopexy between January 2016 and December 2021. Surgical candidates reported grades 2 and 3 of ptosis following Regnault classification. Minimum follow-up was 24 months. Pre- and postoperative data for all patients were collected in the same standard conditions. 89 patients affected with bilateral breast ptosis were included in the study, for a total of 178 breasts. Patients' mean age at the time of surgery was 40.45 years, ranging between 28 and 59 years. Follow-up ranged between 2 and 6 years with an average of 47.13 months. Out of 89 patients, 50 underwent general anesthesia, and the remaining 39 underwent local anesthesia. Among the 178 treated breasts, 10 (17.8%) experienced minor complications: No major complications were reported. Autologous tissue displacement, collecting parenchyma wherever surplus can be recruited, permits the transfer of extra tissue to the lack of volume, recontouring satisfactory breast shape and ensuring long-lasting results.

АНАЛІЗ РОЗПОДІЛУ КОНТАКТНИХ НАПРУЖЕНЬ У ДВОЗРІЗНОМУ БОЛТОВОМУ З'ЄДНАННІ КОМПОЗИТНИХ ТА МЕТАЛЕВИХ ЕЛЕМЕНТІВ

Bolted joining technique is the dominant joining method for CFRP load-carrying structures in aircraft. However, the weak point of such structures are the areas located in the vicinity of the fastener holes, which are the areas of increased stress concentration. In addition, drilling the holes results in structural discontinuities due to cutting material fibers. Among all failure modes of composite bolted joint, bearing failure is one of the most common type of damage. This failure is caused by the local compressive stresses acting normal to the contact surface, that leads to delamination of material due to insufficient strength of matrix. Therefore, it is extremely important to optimize the design of composite bolted joints in order to enhance the entire composite structure. To increase the load-carrying capacity of the composite joint structural parts and protect the hole walls from damage, a method for installing titanium bushing with glue into the holes of composite plate is proposed. The paper presents the results of numerical analysis of the impact of stacking sequence on the distribution of contact stresses in a double-shear bolted joint of composite plate to steel cover plates. Using the finite element method and ANSYS Workbench 2019 R3 software, a three-dimensional finite element model of a double-shear bolted joint was created, which enables to analyze the impact of the stacking sequence on the distribution of contact stresses at the bolts to titanium bushings interface in the case of uniaxial tension of the middle composite plate at the level of tensile stresses in the gross section of 100 MPa. The obtained result explains the fundamental difference in the behavior of composite and metal materials: due to the change in the orientation and sequence stacking, the stiffness of the composite element of the joint changes, which affects the ovalization of the holes and the level of local deformations of the bushings, which in turn leads to a change in the maximum contact stresses and their concentration. By optimizing stacking sequence, it was possible to reduce the level of maximum contact stresses by 1.1 times. At the same time, the degree of unevenness of the distribution of contact stresses decreased by 1.21 times. The optimal stacking sequence was one in which 37.5% of the fibers oriented at an angle of 0°, 50% of the fibers oriented at angles of ±45°, and 12.5% of the fibers oriented at an angle of 90°

One Health Index applied to countries in South America.

The One Health concept has proposed an integrated and unified approach aiming for health balance and enhancement by recognizing the interdependence of human, animal, and environmental health. The COVID-19 pandemic has pushed global One Health initiatives and policy improvement toward preventive measures for future pandemics, particularly of zoonotic origin. Such a scenario may be particularly relevant for South America, which is considered highly vulnerable due to its natural biodiversity superposed to socioeconomic and environmental issues, demanding effective methods and indicators for proper One Health strategies and goals that are aligned with macroregional contexts. Accordingly, the present study aimed to assess the One Health Index (OHI) in South American countries, along with potential interactions with socioeconomic indicators. The results obtained using clustering analysis and permutational multivariate analysis of variance (PERMANOVA) have revealed a positive association between the OHI and the Human Development Index (HDI) but not with gross domestic product (GDP). Although South American countries with political stability, robust investment in health, and progressive policies have shown a higher OHI, better environmental health is not associated with better human and animal health. In addition, although the Amazon biome- spanning 9 of the 12 South American countries-has positively impacted environmental health, this benefit contrasts with the rudimentary local human health systems, highlighting the complexity of One Health within the South American context. The lack of stronger indicators for animal health was also considered an important weak point for a true OHI assessment. Nonetheless, countries with more developed livestock have presented better animal health, which may not reflect an overall animal health indicator, as companion and wildlife animal health indicators were not available. Although lower (within-country) scale analysis such as states and metropolitan areas may better shape internal differences, the study herein has clearly shown One Health inequalities and challenges among South American countries. Equally important, forests and other natural areas in developing countries, particularly the Amazon, should receive incentives to promote sustainable economic growth. This approach would help prevent sacrificing environmental health for the benefit of human and livestock animal health.

Design of Two-Layer Roller Compacted Concrete with Joints by KENSLAB

Roller compacted concrete (RCC) is a type of rigid pavement that is designed in a similar way to conventional concrete pavements reflecting its mode of failure. The thickness design of RCC pavements is based on keeping the flexural stresses and fatigue damage in the pavement caused by wheel loads within allowable limits. As in all jointed concrete pavements, there is a greater effect from loads placed along edges and less at interior locations in the pavement. Joints in RCC pavement are clearly critical areas and form weak points. RCC is typically constructed with saw-cut joints to prevent random cracking, improve the appearance of the pavement surface, and maintain the highest possible load transfer across the joints. This paper presents an approach to designing the thickness of a two-layer RCC with induced cracks (i.e., joints) based on load transfer stiffness and fatigue damage, using the KENSLAB program to obtain pavement life, predict joint deterioration, and pavement damage.

Optimization of small coal pillar width and control measures in gob-side entry excavation of thick coal seams

This study introduces an innovative optimized bolting support system specifically tailored for gob-side entry excavation in thick coal seams at a coal mine in southwestern Shandong, China. Employing theoretical analysis, numerical simulation, and field measurements, the research focuses on examining the failure characteristics of surrounding rock during gob-side entry excavation. The key innovation lies in the development of a 5-meter optimal coal pillar width, ensuring balanced stress distribution and structural integrity. Additionally, a lag time of at least 46 days between gob-side entry excavation and the upper working face retreat is recommended to mitigate roof subsidence and surrounding rock deformation. The optimized bolting support system, featuring increased bolt pretension, utilization of high-strength steel strips, and reinforcement of weak points, effectively reduces deformation of the roadway surrounding rock, meeting support requirements for normal production. This novel approach successfully addresses the support challenges in thick coal seam gob-side entry excavation, enhancing mining safety and resource recovery rates.

Building innovation capability in SMEs through university-business collaboration

Small and medium-sized enterprises (SMEs) often struggle with company innovation, compared to their larger counterparts. A university-business collaboration (UBC) programme in the north of the Netherlands attempts to increase the innovation capabilities of regional SMEs with the support of graduating bachelor students. The 18-months long Hanze Innovation Traineeship Programme (HITP) combines the graduation phase with a consecutive 12-months traineeship, during which students are meant to implement an innovation at the company. We measure the innovation capacity of the participating SMEs at the beginning of the programme and identify strong and weak points within the organisations. We discuss the outcomes of the HITP for SME innovation and further evaluate the programme’s suitability on the intended student learning outcomes.

Modern Approaches to Attracting Personnel to Medical Organizations in Rural Areas on an Example of the Voronezh Region

INTRODUCTION: The importance of this study stems from the necessity to search for an effective solution to the problem of provision of the rural healthcare with medical personnel to increase the quality of medical care and its availability for the population. AIM: To scientifically substantiate and develop proposals for attracting and developing the human resources potential of rural medical organizations. MATERIALS AND METHODS: To assess the state of provision of healthcare in the Voronezh Region (VR) with human resources, the data from statistical accounting forms No. 17 and No. 30 were used. The comparative analysis method was used to study the provision of medical organizations of the VR with medical personnel and staffing with medical positions, and the main parameters of the activity of medical organizations in rural areas of the region. To study the factors contributing to the attraction of young specialists to medical organizations in rural areas, an anonymous online survey was conducted. RESULTS: The analysis of provision of healthcare organizations of the VO with personnel showed a satisfactory level of provision with medical workers. The personnel shortage is more pronounced in rural areas the staffing of full-time positions is decreasing, the influx of young specialists is decreasing, the proportion of people of retirement age is increasing. In-depth analysis permitted to identify ‘weak points’ in the formation of the personnel reserve and take them into account when forming the regional personnel policy. Based on the data obtained during the study, a multi-level model of reproduction of human resources was created using the cluster approach. A mechanism for interaction between potential employers and subjects of the educational system was developed. CONCLUSION: The pooling of resources within the framework of cluster interdepartmental interaction led to the expansion of the career guidance space and permitted to build practice-oriented educational activities based on continuity of general, secondary vocational and higher education. The findings of the study can be used in the formation of an effective personnel policy aimed at advanced forecasting of the process of their reproduction in the healthcare system.

Analysis of the physical mechanisms responsible for the Acoustic Black Hole effect

An acoustic black hole (ABH) inserted into a mechanical structure provides effective vibration damping without making the structure heavier. This property is particularly interesting in contexts where mass reduction is important. In practice, the ABH effect embedded in a beam or in a plate results from the combination of a local reduction in thickness and the addition of a thin viscoelastic damping layer. Consequently, an ABH is a weak point in the structure, which leads to the existence of local modes. An ABH can be seen as a penetrable resonant scatterer, with a high density of modes, all critically coupled. These properties intrinsically define the conditions required to obtain a true ABH effect. This definition will be presented and illustrated on examples of increasing complexity.

Development of vibration isolation system for halls and report on sound insulation and vibration experiment

Rubber and polyurethane have been widely used as vibration isolation materials in halls and studios. In this project, we have developed a floor-mounted coil spring vibration isolator with improved vibration isolation and sound insulation characteristics, while keeping the installation height equivalent or lower than rubber and polyurethane. In this paper, we evaluate the vibration isolation performance of the developed device by measuring vibration transmission loss, and confirm that the device can suppress surging, which is a weak point of metal springs, while achieving a low natural frequency. The sound transmission loss measurement also confirmed that the floating slab incorporating the device has sufficient sound insulation performance, and these results indicate that the device can be applied to acoustic spaces such as concert halls, where quietness is required.

Determining the relevance of noise barriers along railway lines based on a multi-criteria analysis

Rail transport is one of the friendliest in environmental terms, but the noise generated by this mode of transport remains a weak point. To improve local residents' living conditions against this noise, two locations for protection devices are possible : close to the source, to be preferred in accordance with French legislation, within the limit of economical acceptability (not defined) or by façade insulation otherwise. A method has been developed to assess the relevance of noise barriers or merlons based on a cost-benefit analysis. A multi-criteria analysis is required, based on acoustic benefits provided by protection near to the source, building density, number of people protected, technical feasibility, costs directly linked to the construction conditions and landscape integration possibilities. The article details the method used during the preliminary study phase to determine the possible conditions for implementation, the associated costs and the impact of protection, and presents the analysis grids used to validate the choice of protection type, close to the source or on the facade.

B-292 Detection of natural toxins derived from potatoes by biotin-streptavidin direct ELISA

Abstract Background α-solanine (SO) and α-chaconine (CHA) are natural toxins of potato and often cause food poisoning worldwide. We have previously developed a polyclonal antibody (anti-Sold antibody) that bind to SO and CHA and used it in an enzyme-linked immunosorbent assay (ELISA). Our previously constructed ELISA (conventional ELISA) has a weak point of low sensitivity in detecting SO and CHA, we have tried to improve it in this study. Methods Solanidine, a chemical compound found in both SO and CHA, was conjugated with bovine albumin, and this complex was repeatedly injected into two rabbits for two months. Anti-Sold antibody was then purified from rabbit serum using affinity column chromatography. In our ELISA method, named “B-S direct ELISA”, biotin-labeled anti-Sold antibody is bound to SO and CHA in the sample, followed by the binding of peroxidase-labeled streptavidin. To simulate biological samples from patients with potato food poisoning, SO and CHA powders were mixed with commercially available human serum and urine, and SO and CHA levels were then measured using ELISA. Lastly, SO and CHA levels were detected in extracts from rotten potato (Irish Cobbler) sprouts, peels, and tubers. Results The absorbance of the samples containing SO and CHA prepared in 10 mM phosphate buffer saline (PBS) was about 5-fold higher than that of the conventional ELISA. Furthermore, the absorbance of the samples containing SO and CHA prepared in human serum and urine was enhanced about 2.5- and 1.6-fold, respectively, compared to that of the conventional ELISA. The limit of detection in B-S direct ELISA was 0.32 ng/mL in 10 mM PBS, 2.08 ng/mL in serum, and 4.88 ng/mL in urine, respectively. Using this ELISA, it was also possible to measure the content of SO and CHA in extracts of potato tubers, peels, and sprouts. Both SO and CHA in the extracts from rotten potato tubers and peels were detected as approximately 1.4- and 2.2-fold higher, respectively, in each part than those in the extracts from fresh potatoes. Furthermore, the potato sprout extract contained approximately 50-fold more SO and CHA than the tuber and 9-fold more than the peel. On the other hand, B-S direct ELISA cross-reacted with solanidine and solasodine, which have similar chemical structures to SO and CHA, and also with cholesterol and vitamin D3 in serum. Conclusions Based on our results, B-S direct ELISA presented greater performance in detecting SO and CHA than our conventional ELISA. The non-specific reactions in the serum samples and influence of urea in the urine samples may underlie the reduced detection performance of SO and CHA in ELISA, respectively. Although this ELISA has a detection performance applicable to human biological samples, cross-reactivity should be fully considered when judging the results.

Mechanism and controlling factors of mass transport complexes migration: A case study of the mass transport complexes in the taranaki deep water basin, New Zealand

Mass transport Complexes (MTCs) form significant sediment accumulations in continental slopes, hold key insights for natural hazard prediction and offshore oil exploration. This paper uses high-definition 3D seismic data to reconstruct the seismic geomorphology and sedimentary dynamics of MTCs, meticulously exploring the depositional systems of the Tanaraki Basin, New Zealand. It deciphers by kinematic notation, seismic faciess, quantifies megaclast morphological characteristics, in conjunction with the basal slope and channel structure development as the migration or kinematics of MTCs. Five seismic facies categories and dynamic traits—compression ridges, thrust faults, slides, grooves and slope terraces are distinguished in MTCs. Based on attributes maps and geomorphological interpretations, MTCs is segmented into four zones, showing combined effects of levée, basal slopes, and megaclast clusters on its migration. Lithological and topographical variations along these features modulate erosion properties and MTCs mobility, with base height shifts guiding local migration trajectories. The results of megaclast parameters in Zones 1 and 3 tune our understanding of stress patterns and directionality shifts, highlighting the complex dynamics at play. Notably, the differential motion triggered by levees instigates longitudinal shear zones. At critical migration disparities, MTCs fracture at these weak points, discharging pore pressure and filling fractures with fines, birthing “promontory” formations marked by low-amplitude fills. This work, therefore, establishes a groundbreaking migratory model that synthesizes the impacts of levees height, rock type variability, and megaclasts accumulation intensity, depicting a fragmented migration pattern. This study not only enriches our grasp of MTCs behavior in deep-water contexts but also furnishes a robust scientific foundation and predictive tool for gauging the hazards that MTCs may pose to underwater structures, thus carrying substantial theoretical and applied significance.
