Daily mobility practices and urban structure in the peri-urban environment: Lomas Coloradas and Portal de San Pedro, San Pedro de la Paz (Chile)

The aim of this article is to comprehend daily mobility practices in contiguous peri-urban residential areas that have different characteristics in terms of their historical origin, urban design and layout, socioeconomic level, and access to public transportation, using the areas of Lomas Coloradas and Portal de San Pedro in the commune of San Pedro de la Paz. From a quantitative analysis, the level of integration allowed by the urban fabric was analyzed comparatively using the Space Syntax method (Hiller et al., 1987) through the depthMapX software, to then identify the number of facilities and population density based on data from the 2017 census. Finally, mobility was studied by applying semi-structured surveys focused on supply. The results show that the type of urban fabric and its level of local integration lose importance in daily mobility practices when it comes to intercommunal travel. Thus, within the transport offer, just satisfying access to these areas does not ensure the reduction of the urban inequality observed in the daily mobility of people.

Disorder-induced spin-charge separation in the one-dimensional Hubbard model

Many-body localization is believed to be generically unstable in quantum systems with continuous non-Abelian symmetries, even in the presence of strong disorder. Breaking these symmetries can stabilize the localized phase, leading to the emergence of an extensive number of quasilocally conserved quantities known as local integrals of motion, or $l$ bits. Using a sophisticated nonperturbative technique based on continuous unitary transforms, we investigate the one-dimensional Hubbard model subject to both spin and charge disorder, compute the associated $l$ bits and demonstrate that the disorder gives rise to a novel form of spin-charge separation. We examine the role of symmetries in delocalizing the spin and charge degrees of freedom, and show that while symmetries generally lead to delocalization through multiparticle resonant processes, certain subsets of states appear stable.

Recent Immigration from the Republic of Moldova and Arab Countries to Romania. A Stakeholders’ Perspective on Local Integration

Romania, a net emigration country, has witnessed a significant increase in immigration over the last decade. The objective of this paper is to highlight the facilitators and barriers to local integration faced by recent immigrants to Romania, as expressed by relevant stakeholders. Their often neglected views hold particular relevance for improving the well-being and integration of migrants in Romania. We focus on young immigrants from the Republic of Moldova and from Arab countries, relying on the data from 13 interviews conducted in 2021 with various stakeholders. The results of the paper reveal different integration mechanisms for the two groups. Some barriers are similar, being mainly related to document validation and lack of family support. Other factors act differently for the two groups of migrants. For Moldovan youth, language and cultural familiarity facilitate their access to the labour market and education, whereas asylum seekers from Arab countries need longer for achieving local integration.

Local integrals of motion in quasiperiodic many-body localized systems

Local integrals of motion play a central role in the understanding of many-body localization in many-body quantum systems in one dimension subject to a random external potential, but the question of how these local integrals of motion change in a deterministic quasiperiodic potential is one that has received significantly less attention. Here we develop a powerful new implementation of the continuous unitary transform formalism and use this method to directly compute both the effective Hamiltonian and the local integrals of motion for many-body quantum systems subject to a quasiperiodic potential. We show that the effective interactions between local integrals of motion retain a strong fingerprint of the underlying quasiperiodic potential, exhibiting sharp features at distances associated with the incommensurate wavelength used to generate the potential. Furthermore, the local integrals of motion themselves may be expressed in terms of an operator expansion which allows us to estimate the critical strength of quasiperiodic potential required to lead to a localization/delocalization transition, by means of a finite size scaling analysis.

Two‐level stabilized finite volume method for the stationary incompressible magnetohydrodynamic equations

AbstractIn this paper, a two‐level stabilized finite volume method is developed and analyzed for the steady incompressible magnetohydrodynamic (MHD) equations. The linear polynomial space is used to approximate the velocity, pressure and magnetic fields, and two local Gauss integrations are introduced to overcome the restriction of discrete inf‐sup condition. Firstly, the existence and uniqueness of the solution of the discrete problem in the stabilized finite volume method are proved by using the Brouwer's fixed point theorem. ‐stability results of numerical solutions are also presented. Secondly, optimal error estimates of numerical solutions in and ‐norms are established by using the energy method and constructing the corresponding dual problem. Thirdly, the stability and convergence of two‐level stabilized finite volume method for the stationary incompressible MHD equations are provided. Theoretical findings show that the two‐level method has the same accuracy as the one‐level method with the mesh sizes . Finally, some numerical results are provided to identify with the established theoretical findings and show the performances of the considered numerical schemes.

Integration of interictal EEG source localization in presurgical epilepsy evaluation - a single-center prospective study.

To investigate costs in working hours for initial integration of interictal EEG source localization (ESL) into clinical practice of a tertiary epilepsy center, and to examine concordance of results obtained with three different ESL pipelines. This prospective study covered the first year of using ESL in the Epilepsy-Center Berlin-Brandenburg. Patients aged ≥14 years with drug-resistant focal epilepsy referred for noninvasive presurgical evaluation were included. Interictal ESL was based on low-density EEG and individual head models. Source maxima were obtained from two freely available software packages and one commercial provider. One physician and computer scientist documented their working hours for setting up and processing ESL. Additionally, a survey was conducted among epilepsy centers in Germany to assess the current role of ESL in presurgical evaluation. Of 40 patients included, 22 (55%) had enough interictal spikes for ESL. The physician's working times decreased from median 4.7 hours [interquartile range 3.9-6.4] in the first third of cases to 2.0 hours [1.9-2.4] in the remaining two thirds; p<0.01. In addition, computer scientist and physician spent a total of 35.5 and 33.0 working hours on setting up the digital infrastructure, and on training and testing. Sublobar agreement between all three pipelines was 20%, mean measurement of agreement (kappa) 0.13. Finally, the survey revealed that 53% of epilepsy centers in Germany currently use ESL for presurgical evaluation. This study provides information regarding expected effort and costs for integration of ESL into an epilepsy surgery program. Low result agreement across different ESL pipelines calls for further standardization.

A novel reversible fragile watermarking method in DWT domain for tamper localization and digital image authentication

Medical images are extremely valuable and sensitive data because of their significance in research, diagnosis, and treatment. However, the transmission of medical images over an unsecured network can lead to security issues such as modification, removal, copying, and unauthorized access. For this reason, the protection of medical information is of great importance. This paper proposes a novel reversible fragile digital watermarking method for tamper localization and authenticity and integrity protection in medical images. In the proposed method, the host image is firstly divided into 8×8 non-overlapped blocks. Then the image is transformed to the frequency domain by applying a Discrete Wavelet Transform, and the watermark information is embedded. Finally, the image is converted from the frequency domain to the spatial domain using an inverse Discrete Wavelet Transform. During this transformation, an intelligent optimization technique is used to correct the rounding errors and obtain the watermarked image with the highest level of imperceptibility. The experimental results demonstrate that the proposed method offers a watermarked image with high imperceptibility, extracts the host image lossless during the watermark extraction phase, and performs tamper localization with high precision.

What Kind of Weapon Is Education? Teleological Violence, Local Integration, and Refugee Education in Northern Ethiopia

Abstract Why does education damage refugees? To understand this, we need to ask how education frames refugees’ thinking about their future, specifically related to questions of waiting in the camp or migrating through dangerous, irregular channels. Between 2016 and 2019, Ethiopia was at the forefront of trends in migration policy that prioritized education as part of a global strategy to prevent irregular, northward migration. However, despite increased educational opportunities, refugees rejected schooling as they weighed the decision to migrate onwards, citing a sharp disconnect between aspirations connected to schooling and the constraints on professional and personal progress that they face in hosting states. Drawing on long-term, multi-sited, ethnographic research on temporal violence, and temporal agency among Eritrean refugees in Ethiopia, we develop the concept of teleological violence to describe the harm generated by this disconnect, as risky secondary migration may come to seem like the only path toward a desired future.

Internally Displaced Persons in Nigeria: Durable Solution, Assessment and Reviews

The protracted internal displacement crisis in Nigeria has led to significant challenges for the affected population and has strained the country's resources and infrastructure. This paper focuses on the issue of internally displaced persons (IDPs) in Nigeria, exploring the concept of durable solutions, the importance of comprehensive assessments, and the necessity of regular reviews in addressing their plight. The concept of durable solutions forms the cornerstone of addressing displacement crises, aiming to provide sustainable outcomes for IDPs. This study examines the three recognized durable solutions: voluntary return, local integration, and resettlement, and analyzes their applicability in the Nigerian context. It emphasizes the need for a holistic approach that considers socio-economic factors, security conditions, and the protection of IDPs' rights. Comprehensive assessments play a vital role in understanding the needs and vulnerabilities of IDPs, facilitating informed decision-making and resource allocation. This study highlights the importance of conducting thorough assessments, including demographic data, living conditions, access to basic services, and psychosocial support. It emphasizes the role of government agencies, humanitarian organizations, and research institutions in undertaking these assessments to guide effective interventions. Regular reviews of displacement situations are crucial to monitor progress, identify gaps, and adapt strategies accordingly. This study emphasizes the significance of periodic evaluations of policies, programs, and interventions aimed at addressing internal displacement in Nigeria. It underscores the importance of stakeholder involvement, including IDPs themselves, in these review processes to ensure their perspectives are considered and their voices heard. Furthermore, the work acknowledges the challenges inherent in addressing the plight of IDPs in Nigeria, including limited resources, security concerns, and the complexity of the underlying causes of displacement. It emphasizes the need for a coordinated and multi-stakeholder approach, involving the government, humanitarian actors, civil society, and the international community, to achieve durable solutions for IDPs.

Exploring 3D spatial morphology using multilayered space syntax, network science and wi-fi log data

Spatial morphology of 2D space has been well studied at the scales of building, community, and city in space syntax literature. Space syntax decomposes continuous geographic space into a set of unique axial lines and represents them as a spatial network to analyze spatial morphology. However, 3D spatial morphology remains largely unexplored, partially due to limited data access and methodological constraints. Motivated by the multilayered network literature in network science, this work extends the conventional 2D space syntax axial network into a multilayered axial network to explore the spatial morphology of a university campus. Scaling properties are discovered from several aspects of the constructed spatial network (e.g., degree, local integration). The relationship between spatial morphology and route-based pedestrian flow is evaluated using a large Wi-Fi log dataset and multiple regression analysis. We found a significant correlation between the two, with a correlation coefficient of 0.756 and r2 of 0.571. Four network features (i.e., local depth, geometric length, eigenvector, and betweenness), are found to significantly shape the pedestrian flow. The results of community detection show the effectiveness of multilayered space syntax analysis in depicting functional areas of campus, despite the complex nature of 3D space. Whilst a limitation of this research is the need to account for the 3D angular route preferences when characterizing the morphology of campus and the flow estimated based on the shortest routes using the Dijkstra algorithm.

Young Refugees’ Integration Trajectories—The Critical Role of Local Resources in Germany

Though it is a global phenomenon, migration results in a variety of local outcomes. Depending on migrants’ specific arrival contexts, countries of origin and migration motives, they are channelled into different categories. As a result, they encounter unequal access to different domains at the local level. This paper analyses how young migrants in vulnerable conditions are able to access and use local or localised resources and to what extend these resources enable them to overcome structural barriers over time. Our analysis builds on empirical findings from a case study in Dortmund, Germany, conducted through the EU-funded MIMY project. Drawing on narrative interviews with young refugees (aged 18–29), it highlights three specific cases where temporal and spatial factors shape individual integration pathways. The narratives highlight the barriers encountered by young refugees, most of which are related to migrant policy categories implemented at national or supra-national levels. In the arrival context, the young migrants are able—to varying degrees—to mobilise localised resources helping them overcome (at least partially) such mainly structural barriers. Focusing on the emergence and evolution of local integration landscapes thus reveals the importance of time and the difference time makes in terms of the availability of resources and legal frameworks.

A multi-stage coupling adaptive method for thermochemical nonequilibrium gas

A multi-stage coupling adaptive simulation method for thermochemical nonequilibrium gas is introduced. Based on the mathematic ideal of Lambert's local integration method, the method decomposes the time integration process of the thermochemical nonequilibrium steady flow simulation into multiple ladder-type advancing stages from simple to complex, and applies the progressive approximation strategy of gradually coupling characteristic equations of thermochemical effects to achieve the rapid flowfield simulation. Second, numerical comparative analysis are conducted on the arc-jet wind tunnel test flow conditions of the hemisphere model with radius of R = 50.8 mm. Finally, numerical evaluation of the aerothermal characteristics is carried out for the typical flow state of the OV102-like space shuttle model. The numerical studies show that the new method has excellent effect of accelerating the convergence. Compared with the commonly used uniform advancing implicit method of the tight coupling of flow/thermochemical reactions, the computational efficiency is improved by about 1/3 in the one-temperature 5-species chemical model, and nearly 1 time in the two-temperature 11-species thermochemical model. In addition, the method shows good computational reliability and numerical stability, and can satisfy the requirement of the simulation of the hypersonic flows over complex topological configurations under the large CFL number condition.

Towards a Cross-Cultural Hybridisation: An Exploration of Furniture Design and Advertising in Shanghai, China (1912-1949)

ABSTRACT This paper uses furniture advertisements to explore interactions between Eastern and Western design forms in semi-colonial Shanghai during the Republic of China (1912–1949). 1 By analysing historical advertisements during this period, it identifies three distinct trends in furniture design that integrated Eastern and Western influences in an innovative manner, reflecting, to varying degrees, a “cross-cultural hybridization” of forms. 2 The first trend celebrated Western design, which was introduced to Shanghai during its colonisation in the late Qing Dynasty (1845–1912), rendering it in traditional Chinese materials and construction techniques. The second trend, which aligned with the anti-imperial sentiment of Shanghai society after the founding of the Republic of China, celebrated local craftsmanship either by referencing traditional Chinese furniture design, or highlighting local production. These two trends led to the creation of a truly integrative third trend, the “Modeng” style, which blended Eastern and Western design elements and became a hallmark of Shanghai design and culture after the 1930s. Overall, by tracing the evolving trends of Shanghai furniture design, this article enhances our comprehension of the intricate relationship between Western cultural influences and local adaptations and integrations, highlighting how furniture advertisements reflected Shanghai’s unique cultural context.

Antemortem network analysis of spreading pathology in autopsy-confirmed frontotemporal degeneration.

Despite well-articulated hypotheses of spreading pathology in animal models of neurodegenerative disease, the basis for spreading neurodegenerative pathology in humans has been difficult to ascertain. In this study, we used graph theoretic analyses of structural networks in antemortem, multimodal MRI from autopsy-confirmed cases to examine spreading pathology in sporadic frontotemporal lobar degeneration. We defined phases of progressive cortical atrophy on T1-weighted MRI using a published algorithm in autopsied frontotemporal lobar degeneration with tau inclusions or with transactional DNA binding protein of ∼43 kDa inclusions. We studied global and local indices of structural networks in each of these phases, focusing on the integrity of grey matter hubs and white matter edges projecting between hubs. We found that global network measures are compromised to an equal degree in patients with frontotemporal lobar degeneration with tau inclusions and frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions compared to healthy controls. While measures of local network integrity were compromised in both frontotemporal lobar degeneration with tau inclusions and frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions, we discovered several important characteristics that distinguished between these groups. Hubs identified in controls were degraded in both patient groups, but degraded hubs were associated with the earliest phase of cortical atrophy (i.e. epicentres) only in frontotemporal lobar degeneration with tau inclusions. Degraded edges were significantly more plentiful in frontotemporal lobar degeneration with tau inclusions than in frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions, suggesting that the spread of tau pathology involves more significant white matter degeneration. Weakened edges were associated with degraded hubs in frontotemporal lobar degeneration with tau inclusions more than in frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions, particularly in the earlier phases of the disease, and phase-to-phase transitions in frontotemporal lobar degeneration with tau inclusions were characterized by weakened edges in earlier phases projecting to diseased hubs in subsequent phases of the disease. When we examined the spread of pathology from a region diseased in an earlier phase to physically adjacent regions in subsequent phases, we found greater evidence of disease spreading to adjacent regions in frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions than in frontotemporal lobar degeneration with tau inclusions. We associated evidence of degraded grey matter hubs and weakened white matter edges with quantitative measures of digitized pathology from direct observations of patients' brain samples. We conclude from these observations that the spread of pathology from diseased regions to distant regions via weakened long-range edges may contribute to spreading disease in frontotemporal dementia-tau, while spread of pathology to physically adjacent regions via local neuronal connectivity may play a more prominent role in spreading disease in frontotemporal lobar degeneration-transactional DNA binding protein of ∼43 kDa inclusions.

Access to language training and the local integration of refugees

This paper examines whether language classes raise refugees’ language proficiency and improve their socio-economic integration. Our identification strategy leverages the opening, closing, and gradual expansion of local language training centers in Denmark, as well as the quasi-random assignment of the refugees to locations with varying proximity to a language training center. First, we show that refugees’ distance from the assigned language training center is as good as random conditional on initial placement. Second, we show that a one-hour decrease in commuting time increases the total hours of class attended by 46 to 71 hours. Third, we use this novel identification strategy to show that 100 additional hours of language class increases fluency in the Danish language by 8–9 percent, post-language training human capital acquisition by 11–13 percent and improve the integration of the refugees in the communities where they were initially placed, as measured by the lower exit rates from those same communities and an almost 70 percent reduction in mobility to the largest, most immigrant-dense cities in Denmark.

Residual-Based Fault Detection and Exclusion With Enhanced Localization Integrity

In this paper, we give an integrity framework for vehicle localization in urban environments based on fusion of GPS and dead reckoning. To guarantee localization integrity, a novel Kalman filter-based fault detection and exclusion method is presented to reject faulty measurements via a chi-square test with iterative residuals. For a tight upper-bound for position error, we introduce a protection level calculation method with minimum detectable bias and the integrity budget allocation among all failure modes have been improved to enhance the accuracy of positioning. The algorithm provides integrity assessment and reliable estimations of vehicle position information in an iterative manner. Numerical simulations and experiments show that the proposed method can effectively deal with and recover from abrupt faults with a low rate of false alarm and a tight integrity risk bound.

Intestinal Epithelial Cell PTPN2 Restricts Intestinal Permeability and Tight-Junction Remodelling Caused by Adherent-invasive E. coli in Mice

Background: Alterations in epithelial tight junction proteins can compromise the ability of the intestinal mucosa to act as a barrier between luminal contents and underlying tissues. The resulting increase in intestinal permeability can give rise to conditions such as inflammatory bowel disease (IBD). Additionally, expansion of pathobionts, such as adherent-invasive Escherichia coli (AIEC), are associated with IBD. Mice deficient in the IBD gene candidate, Ptpn2, exhibit increased intestinal permeability and a pronounced expansion of a novel murine AIEC ( mAIEC). This study aimed to investigate how PTPN2 expression in intestinal epithelial cells protects intestinal barrier properties after mAIEC infection. Methods: Tamoxifen-inducible, intestinal epithelial cell (IEC)-specific knockout mice ( Ptpn2 ΔIEC ) and control littermates ( Ptpn2 fl/fl ) were infected with either PBS, non-invasive E. coli K12, or mcherry-tagged mAIEC ( mAIEC red ). FITC-Dextran (FD4) and Rhodamine-Dextran (RD70) permeability probes were administered by oral-gavage and serum collected after 5hrs. Results: Ptpn2 ΔIEC mice exhibited intestinal region-specific higher mAIEC red - but not K12 - bacterial load compared to Ptpn2 fl/fl mice ( P=0.038). E. coli K12 increased FD4 but not RD70 permeability in Ptpn2 ΔIEC mice compared with Ptpn2 fl/fl mice ( P=0.0025). mAIEC red also had no effect on RD70, but caused an even greater increase in FD4 permeability in Ptpn2 ΔIEC vs. Ptpn2 fl/fl mice ( P&lt; 0.0001). Ptpn2 fl/fl mice infected with mAIEC red also exhibited increased FD4 permeability compared to PBS-treated littermates ( P =0.0210). To identify if increased FD4 permeability was due to changes in expression of relevant tight-junction proteins, we performed western blot analysis on isolated IECs. Ptpn2 ΔIEC + mAIEC red mice had decreased expression of occludin ( P=0.0030) and the adherens junction protein, E-cadherin ( P=0.0142). Expression of the cation pore, claudin-2, was increased in PBS and K12-infected Ptpn2 ΔIEC vs. Ptpn2 fl/fl mice ( P=0.015). Interestingly, mAIEC red increased claudin-2 expression in Ptpn2 fl/fl mice compared to PBS controls ( P=0.0105) however, Ptpn2 ΔIEC + mAIEC red mice exhibited decreased claudin-2 levels compared to Ptpn2 fl/fl + mAIEC red mice ( P=0.0436). Immunofluorescence staining of claudin-2 confirmed reduced claudin-2 in Ptpn2 ΔIEC + mAIEC red mice. Furthermore, we observed gaps in ZO-1 membrane localization in Ptpn2 ΔIEC mice treated with PBS and K12 but not in their Ptpn2 fl/fl controls. ZO-1 membrane localization was dramatically depleted in Ptpn2 ΔIEC + mAIEC red mice compared to the Ptpn2 fl/fl + mAIEC red controls. Conclusion: Intestinal epithelial PTPN2 exhibits a major role in maintaining intestinal homeostasis by preserving intestinal barrier function and the integrity of tight-junction protein localization. Given that loss of PTPN2 in vivo also provokes expansion of adherent-invasive E. coli, these studies indicate that PTPN2 is an important mediator of host-microbiota crosstalk.

On Generalized Harmonically ψ-MT-Convex Functions via Local Fractional Integrals and some Applications

On Generalized Harmonically ψ-MT-Convex Functions via Local Fractional Integrals and some Applications

A longitudinal study identifies progressive alterations in brain white matter microstructure and networks in male adults with obstructive sleep apnea and their recovery after sleep surgery (P2-13.005)

<h3>Objective:</h3> We aimed to investigate the effects of surgical treatment on the white matter (WM) microstructure and connectivity. <h3>Background:</h3> Obstructive sleep apnea (OSA) is an increasingly prevalent clinical problem resulting in significant effects on quality of life and cognitive impairments. Surgical treatment is an effective treatment for those unable to use positive airway pressure (PAP), but the therapeutic effect of upper airway surgery on the brain has yet to be determined. <h3>Design/Methods:</h3> Twenty-one male patients with moderate to severe OSA were recruited for multi-level sleep surgery. Overnight polysomnography (PSG), neuropsychiatric tests and brain MRI scans were acquired before surgery and at least 6 months after surgery. Nineteen male patients with untreated OSA were also included as a reference group and with follow-up for 1 year or longer. We calculated the interscan changes of DTI parameters including fractional anisotropy ( FA) in the treated and untreated groups. We also assessed changes in network/connectivity properties based on graph theory. <h3>Results:</h3> Surgically treated patients showed improvement in daytime sleepiness, PSG parameters and verbal memory score after surgery. Globally FA was significantly in the surgical group compared to the untreated group; the untreated group showed disease progression (negative FA) whereas the treated group displayed no progression (near-zero FA). Especially, FA of the tracts involved in the limbic system was higher after surgery. In the analysis of network property metrics, between ness of the right cuneus and frontal pole was significantly higher and clustering coefficient of bilateral post central area was lower in the surgical group compared to the untreated group. <h3>Conclusions:</h3> Surgical treatment of OSA can prevent progressive alterations in WM microstructural integrity and disruptions in local network integration and segregation. The positive effects of surgery were prominent for the tracts involved in the limbic system, which may further explain the cognitive improvement observed after the treatment of OSA. <b>Disclosure:</b> Hea Ree Park has nothing to disclose.

Integration of simultaneous fMRI and EEG source localization in emotional decision problems

Simultaneous EEG-fMRI has been a powerful technique to understand the mechanism of the brain in recent years. In this paper, we develop an integrating method by integrating the EEG data into the fMRI data based on the parametric empirical Bayesian (PEB) model to improve the accuracy of the brain source location. The gambling task, a classic paradigm, is used for the emotional decision-making study in this paper. The proposed method was conducted on 21 participants, including 16 men and 5 women. Contrary to the previous method that only localizes the area widely distributed across the ventral striatum and orbitofrontal cortex, the proposed method localizes accurately at the orbital frontal cortex during the process of the brain's emotional decision-making. The activated brain regions extracted by source localization were mainly located in the prefrontal and orbitofrontal lobes; the activation of the temporal pole regions unrelated to reward processing disappeared, and the activation of the somatosensory cortex and motor cortex was significantly reduced. The log evidence shows that the integration of simultaneous fMRI and EEG method based on synchronized data evidence is 22,420, the largest value among the three methods. The integration method always takes on a larger value of log evidence and describes a better performance in analysis associated with source localization.
