    Prediction and inference in complex networks: A brief review and perspectives

    No full text
    Inference and prediction are fundamental to the study of complex systems, where network data are often incomplete, inaccurate or obtained indirectly. In this paper, we review recent advances in network sampling and comparison, as well as in link prediction and network reconstruction from time series. We summarise key methodological developments and emerging approaches that integrate statistical and machine learning perspectives. We also outline promising research directions for enhancing the inference and prediction of complex networked systems

    Visualisation et amélioration de la force : vers un renforcement de la liaison cerveau-muscles chez l’athlète

    La représentation mentale d’une activité motrice fictive, c’est-à-dire pensée mais non réalisée, qu’on dénomme Imagerie Motrice (IM), active des réseaux encéphaliques proches de ceux impliqués dans l’exécution motrice réelle et constitue un levier original d’optimisation des performances neuromotrices. Nos travaux, à l’interface entre neurosciences fondamentales et applications de terrain, montrent que l’IM peut induire une plasticité cérébrale, améliorer la force musculaire et favoriser le transfert inter-habiletés chez des athlètes experts. Nous proposons de considérer l’IM comme une stratégie de neuromodulation endogène, dont le potentiel s’amplifie lorsqu’elle est intégrée à la pratique physique ou combinée à des stimulations périphériques non invasives. Cette approche ouvre la voie à de nouveaux paradigmes de reprogrammation neuromotrice, visant à identifier les conditions optimales de remodelage des réseaux perception-action. Nos résultats suggèrent que l’IM pourrait devenir un outil central pour l’entraînement de la très haute performance et la rééducation neuromotrice

    Influence of modulation parameters on the self-focusing characteristics of rectangular Airy vortex beam

    No full text
    This study investigates the self-focusing characteristics of a rectangular Airy vortex beam (RAVB) via phase modulation. Numerical simulations are conducted to examine the influence of modulation parameters, including linear factor (c), topological charge (l) and wavelength (λ) on RAVB self-focusing characteristics. The focus depth, focus spot size and peak intensity of RAVB can be effectively controlled via the modulation parameters. Among these parameters, c has the most significant impact on RAVB self-focusing characteristics. As c increases from 4 to 8, the focus depth changes from 8 cm to 41 cm, while the peak intensity increases to 50 times. Although variations in l and λ also contribute to increases in both focus depth and peak intensity, their effects are relatively minor compared to those of c

    Typologies of commuter train stations: A case study Jakarta Kota – Bogor agglomeration in Indonesia

    No full text
    Commuter rail is critical for sustainable mobility in suburban and urban areas. Categorizing commuter rail stations from a TOD perspective become typology can provide valuable references for developing, planning, and managing commuter rail station areas. However, limited commuter rail stations at the neighborhood scale must be identified based on TOD factors, specifically in relation to ridership travel patterns. This study addresses this gap by developing a neighborhood-scale TOD typology for station areas using a cluster-multilevel modeling approach to analyze the relationship between TOD factors and passenger travel patterns. This analysis identifies whether a station functions as a trip generator or an attraction point for passengers. A two-step cluster analysis of spatial data from 24 stations along the Jakarta Kota-Bogor rail line resulted in three neighborhood types. Identifying commuter rail station typologies is crucial for policymakers to propose different strategies. These strategies may include small projects to improve public spaces and promote eco-friendly mobility or more substantial changes requiring a density redistribution around the stations. This approach challenges the rigid definition of transit-oriented development and adapts decisions to the specific context of each station area

    Social interaction in urban park: A systematic analysis of design attributes and behavioural outcomes

    No full text
    Urban parks play an essential role in fostering social interactions and community cohesion. This systematic literature review analyses how design attributes of urban parks affect social interactions and delineates the resulting behavioural outcomes. We conducted a rigorous search of the Scopus database for empirical studies published from 2015 to 2025, using keywords such as urban parks, social interaction, landscape design attributes, and quality design. Studies were selected for inclusion if they had clear empirical relevance to park design and social interaction. Major themes identified include spatial configuration, facilities and amenities, natural aesthetics, multi-sensory factors, perceived safety and accessibility, and cultural context. The findings reveal that integrated spatial layouts, accessible pathways, inclusive amenities, visually diverse natural elements, sensory-rich environments, strong safety measures, and culturally resonant features all enhance park usage and social interactions. Multi-sensory design elements, clear sightlines, universally accessible amenities, and culturally meaningful landscapes emerged as especially important for encouraging robust community interactions. Overall, this review demonstrates that thoughtful, inclusive park design can profoundly shape urban social dynamics and highlights critical priorities for policy and design improvements. Future research should explore the long-term socio-cultural impacts of park design, undertake comparative international studies, and apply advanced analytical techniques to optimize park planning. These insights underscore the importance of comprehensive, culturally aware urban design in fostering vibrant, inclusive communities

    This study examines the adoption of technology in the African mining sector, with a focus on digital integration to enhance sustainability, safety, and efficiency. It examines developments in Mining 4.0 around the world and points out obstacles specific to Southern Africa. PRISMA was used to do a systematic literature review (2020–2025) across five databases. The lack of an integrated framework that combines the Tech-Technology Organisation Environment (TOE), Diffusion Of Innovation (DOI), and Unified Theory of Acceptance and Use of Technology (UTAUT) models, and the scant attention paid to user interfaces and human-centric design (HCD), and the lack of contextual specificity In the research that has already been done, there are significant gaps. The goal of the study is to develop a comprehensive, inclusive framework suited to the area’s diverse workforce and socio-technical realities

    Understanding Pressure Excursions in Extracorporeal Technologies: The Role of Shear Stress and Hematologic Predisposition

    No full text
    Background: Mechanical forces within extracorporeal circulation systems such as cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO) can profoundly alter blood physiology. Elevated pressure drops across membrane oxygenators generate abnormal shear stress capable of activating platelets through calcium-dependent mechanotransduction pathways. Activated platelets may adhere to oxygenator fibers, forming microaggregates that progressively increase resistance, impair gas exchange, and contribute to high pressure excursions (HPE). Understanding this mechanobiological loop is essential to improving oxygenator performance and patient safety. Materials and Methods: This narrative mini-review was developed through a structured literature search conducted in PubMed, Scopus, and Web of Science. Studies published in English and focusing on shear stress, platelet activation, and oxygenator function during extracorporeal life support were considered. Keywords included: “platelet activation,” “shear stress,” “extracorporeal circulation,” “ECMO,” “cardiopulmonary bypass,” “oxygenator failure,” “pressure drop,” “high pressure excursion,” “mechanotransduction,” and “platelet aggregation.” After title/abstract screening and full-text assessment, 13 articles met the inclusion criteria and were analyzed to synthesize current mechanistic and clinical evidence. Results: The literature shows that elevated shear stress within oxygenators can directly activate platelets independently of biochemical agonists. Shear-mediated calcium influx initiates platelet shape change, adhesion, and aggregation along hollow fibers, promoting progressive flow obstruction and increasing transmembrane pressure drop. This contributes to a self-reinforcing cycle in which rising resistance further elevates shear, amplifying platelet activation and accelerating oxygenator dysfunction. Conclusions: Shear-induced platelet activation represents a central mechanism in the development of pressure excursions and early oxygenator failure during extracorporeal support. Recognition of this mechanobiological cycle has important implications for oxygenator design, surface biocompatibility, anticoagulation management, and real-time monitoring strategies. A deeper understanding of platelet mechanotransduction may contribute to improving device longevity and enhancing clinical safety in CPB and ECMO

    Optimization of sodium metabisulfite concentration and drying temperature to enhance the quality of breadfruit starch using response surface methodology

    No full text
    Breadfruit (Artocarpus altilis) is an underutilized tropical crop widely cultivated in Indonesia, offering considerable potential as a sustainable source of starch for food applications. However, the quality of breadfruit starch is highly influenced by processing conditions. This study aimed to optimize sodium metabisulfite concentration and drying temperature to improve the yield (Y1) of breadfruit starch using Response Surface Methodology (RSM). A Central Composite Design (CCD) with two factors, sodium metabisulfite concentration (X1: 0.2–0.5%) and drying temperature (X2: 50–70 °C), was applied, resulting in 14 experimental runs. The quadratic model provided the best fit to describe the effects of sodium metabisulfite concentration and drying temperature on starch yield. At the optimum conditions of 0.324% sodium metabisulfite and 62.75°C drying temperature, the model predicted a starch yield of 6.164% with a desirability level of 0.922. These predictions were experimentally validated, yielding 6.119% respectively. The close agreement between predicted and observed values highlighted the effectiveness of RSM in optimizing processing parameters to improve breadfruit starch quality. This work delivers a robust optimization framework that directly supports future research on process scale-up, functional refinement, and the broader industrial deployment of breadfruit starch

    Coffee plantations in the Argopuro Mountains region of Jember Regency, East Java, are relatively old, having been planted during the Dutch colonial era. The purpose of this study was to assess soil fertility and land suitability for coffee cultivation in this region. Soil surveys and soil sampling were conducted at 50 locations across the coffee plantations. Soil samples were analyzed at the Jember State Polytechnic Soil Laboratory. Laboratory analysis are soil texture, organic carbon, soil pH, CEC, and nitrogen, phosphorus, and potassium. Soil fertility status was determined based on soil fertility value criteria from Bogor Soil and Climate Research Center, Indonesia, and land suitability for coffee plants was determined based on the criteria of the Indonesian Coffee and Cocoa Research Center. The results showed that the coffee land in the survey area is classified as low to moderate in fertility. The soil development has entered the senile stage to final stage. Land suitability for coffee cultivation ranges from Very Suitable (S1) to Moderately Suitable (S2). For future, organic matter management and increased N, P, and K nutrients are required. The research are very necessary for the improvement and development of coffee plants in the future
