AIR POLLUTION EXPOSURE AND HEALTH EFFECTS: CELL-SHED MICROVESICLES AS CARRIERS FOR INTERCELLULAR COMMUNICATION
Creators: name: MERCORIO, ROBERTA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: Air pollution exposure is a major problem worldwide and is associated with several diseases, but the molecular mechanisms underlying these associations still remain unknown. Obesity may increase susceptibility to the adverse effects of PM exposure, exacerbating the effects of PM on human health. Extracellular vesicles (EVs), which travel in body fluids and transfer molecular messages among tissues, might play an important role in connecting external exposures to health effects. We examined the effects of PM exposure in a population of 50 healthy subjects stratified for BMI on molecular alterations (Epstein Barr and Human endogenous retrovirus viral sequence methylation and telomere length modification), through a modulation of oxidative stress markers (mtDNA CN and 8OHdG). Our results revealed 8-hydroxydeoxyguanosine (8OHdG) decrease in response to short term exposure for both PM10 and PM2.5, in particular at day -3, -5, -6, -7. The effect was mainly determined by overweight subjects. On the contrary PM exposure was associated to an increased Telomere Length (TL), in overweight subjects only. The effect was maximum for day -3 and day -5 both for PM10 and PM2.5. Interestingly, both oxidative stress markers showed a negative association with TL again only in overweight subjects. DNA methylation has been associated to viral sequence reactivation, for this reason we have investigated methylation changes in Wp and Cp promoter for Epstein Barr virus (EBV) and Human Endogenous virus (HERV-w) in association with PM exposure observing a significant association at day -3 and day -4, -5, -6 respectively. The effect of PM on DNA methylation doesn?t seem to be modified by BMI of the subjects. This finding was also confirmed in vitro, as we treated Akata cell lines with PM and we observed an hypomethylation in EBV promoter, such as an increased expression of BZLF1, which is the first protein expressed in the reactivation of the lytic cycle of EBV.

description: Enhanced early life nutrition accelerates sexual development in the bull calf through neuroendocrine-signalling mediated via the hypothalamic–pituitary–testicular axis. Our aim was to assess the impact of contrasting feeding regimes in bull calves during the frst 12 weeks of life on the testes transcriptome and proteome. Holstein–Friesian bull calves were ofered either a high (HI) or moderate (MOD) plane of nutrition, designed to support target growth rates of 1.0 and 0.5 kg/day, respectively. At 12 weeks of age all calves were euthanized, testicular parenchyma sampled, and global transcriptome (miRNAseq and mRNAseq) and proteome analyses undertaken. Bioinformatic analyses revealed 7 diferentially expressed (DE) miRNA and 20 DE mRNA. There were no diferentially abundant proteins between the two dietary groups. Integration of omics results highlighted a potential role for the cadherin gene, CDH13, in earlier reproductive development. Furthermore, co-regulatory network analysis of the proteomic data revealed CDH13 as a hub protein within a network enriched for processes related to insulin, IGF-1, androgen and Sertoli cell junction signalling pathways as well as cholesterol biosynthesis. Overall, results highlight a potential role for CDH13 in mediating earlier reproductive development as a consequence of enhanced early life nutrition in the bull calf.

description: Este artigo tem como objetivo analisar como a dança do ventre foi representada no Brasil. Nota-se que houve dois momentos marcantes na configuração de um novo cenário para a dança no país: o lançamento da música e do videoclipe Ralando o Tchan (1997) pelo grupo de axé É o Tchan; e a transmissão da novela O Clone (2001) pela emissora de televisão Rede Globo. Assim, partindo da perspectiva de que os sujeitos são ativos e responsivos (Bakhtin, 1975), este trabalho examina como os sujeitos interpretaram a representação discursiva da dança do ventre como um produto cultural pela mídia. Para tal, são analisados discursos coletados (1) por meio de um questionário aberto entre os profissionais da dança no Brasil; e, (2) por meio de um questionário fechado, o que pensa o público em geral. Como fundamentação teórica, são retomados Giddens (1991, 2000), Adorno e Horkheimer (1978), Foucault (1975, 1977), entre outros.

description: This review article describes the performance of the magnetic field measuring and monitoring systems for the Compact Muon Solenoid (CMS) detector. To cross-check the magnetic flux distribution obtained with the CMS magnet model, four systems for measuring the magnetic flux density in the detector volume were used. The magnetic induction inside the 6 m diameter superconducting solenoid was measured and is currently monitored by four nuclear magnetic resonance (NMR) probes installed using special tubes outside the barrel hadron calorimeter. Two more NRM probes were installed at the faces of the tracking system. The field inside the superconducting solenoid was precisely measured in 2006 in a cylindrical volume of 3.448 m in diameter and 7 m in length using 10 three-dimensional (3D) B-sensors based on the Hall effect. These B-sensors were installed on each of the two propeller arms of an automated field-mapping machine. In addition to these measurement systems, a system for monitoring the magnetic field during the CMS detector operation has been developed. Inside the solenoid in the horizontal plane, 4 3D B-sensors were installed at the faces of the tracking detector. Twelve 3D B-sensors were installed on the surfaces of the flux-return yoke nose disks. Seventy 3D B-sensors were installed in the air gaps of the CMS magnet yoke. A specially developed flux loop technique was used for the most complex measurements of the magnetic flux density inside the steel blocks of the CMS magnet yoke. The flux loops are installed in 22 sections of the flux-return yoke blocks. The areas enclosed by these coils varied from 0.3 to 1.59 m$^{2}$ in the blocks of the barrel wheels and from 0.5 to 1.12 m$^{2}$ in the blocks of the yoke endcap disks. The development of these systems and the results of the magnetic flux density measurements across the CMS magnet are presented and discussed in this review article.

description: The article is devoted to the problems of development of Ukrainian ethnology under the influence of Soviet government policies in the 1920s. The article analyses the basic principles of Soviet government and Communist Party policies in the field of science and culture, their relations with scientific institutions and scientists as a social class. The main achievements of Ukrainian ethnology in this period, the process of its institutionalization and theoretical and methodological formation, as well as the peculiarities of its development in the European context are considered. The author analyses the evolution of the Bolshevik government policies in the direction of strengthening control over the professional activities and personal life of Ukrainian ethnologists. It was concluded that a certain liberalization of the policy of the Soviet government in the field of science in 1920-1927 contributed to the emergence of a large number of new ethnographic studies and the entry of Ukrainian ethnology to a qualitatively new level of development.

description: É, na contemporaneidade, importante perceber as interações entre a produção artística e o público. Neste artigo formula-se, partindo da frase de Paul Klee “a maioria não está connosco”, uma reflexão no sentido de perceber o fenómeno que se conhece como divórcio público-arte. Faz-se um enquadramento do fenómeno e, recorrendo a teses de Max Horkheimer e Theodor Adorno, relativas à indústria cultural e a teses de Gilles Lipovetsky, que aborda o tema da hipermodernidade, pretende-se compreender a expressão deste afastamento entre público e arte na sociedade atual. Neste sentido, temas como a mediação e a componente performativa da arte, a capacidade sensível e percetiva do público na circunstância histórica e a hipermodernidade e a relação do individuo com o tempo, tornam-se temas indispensáveis de ser abordados para a presente análise.

description: The freedom of the press –or the freedom of expression –traces its roots in the enlightenment period. Oftenpresented as the "fourth power" – sometimes as "counter-power" –free press is considered a feature of liberal-democracies, and a fundamental human right.This brief article explores the validity of these definitions and the role of the press in democratic societies characterized by governments constrained by checks and balances. Most of this paper draws on my previously published works.

description: L’écaillage des bétons est un phénomène brutal pouvant être préjudiciable pour la stabilité d'une structure pendant et après un incendie. Ce phénomène dépend de la composition du matériau, du chargement thermique mais aussi du changement mécanique appliqué. Ces dernières années, des études théoriques et expérimentales ont tenté d'examiner les causes possibles de l'écaillage des bétons. En particulier, de nombreuses discussions autour de l'importance relative des mécanismes thermomécaniques et thermohydriques ont été menées. Afin de mieux comprendre l'effet du chargement mécanique sur l'écaillage des essais feu ISO ont été conduits sur des dalles sollicitées en compression biaxiale. Des calculs thermomécaniques (TM), reproduisant le déroulement des essais, ont été effectués avec le code aux éléments finis CAST3M. Le travail réalisé a permis de bien prédire à la fois l'évolution des températures mais aussi des déplacements dans les dalles.

description: One of the biggest challenges in conducting a library literacy session via zoom during the COVID-19 pandemic was to create a platform where the students could work in a group. While a majority of the students quickly became accustomed to working in a breakout room setting, it was still difficult for them to fully engage with their classmates. It was also challenging for instructors to measure the students’ engagement level while everyone was working online. In this presentation, I will discuss how I used Google Jamboard for a higher-level Japanese Studies undergraduate class in the Spring 2021 semester. I assigned a Google Jamboard for each student, and they constructed an online “research concept map” where they listed possible keywords in English and Japanese for their capstone project. All Jamboards were shared among the students, so each student was also asked to add keywords in their classmates’ Jamboards. As a bonus of using an online board, some students inserted images, which resulted in a more dynamic and visual board and offered opportunities for the students to start a vivid conversation. The use of Google Jamboard also helped the faculty member and me to monitor the students' progress.
Interactions between the land surface and the near-surface atmosphere : implications for evaporative demand and evapotranspiration under a changing climate
Creators: name: Kim, Yeonuk
Publisher: name: University of British Columbia
Year: 2022

description: Terrestrial evaporation (also referred to as evapotranspiration) is a central variable controlling water, energy, and carbon cycles. However, our ability to estimate evapotranspiration is hampered by the uncertainties in parameterizations of land surface conditions in currently available models. Although the near-surface atmosphere both drives evapotranspiration and is also changed by evapotranspiration (i.e., land-atmosphere feedback), some evapotranspiration models cannot properly address this feedback process. This thesis addresses this critical knowledge gap by introducing a series of alternative theories that consider land-atmosphere interactions, predict potential evaporation, and estimate actual evapotranspiration. Overall, the goal of this thesis is to provide improved tools for use in hydrology and water resources management along with a detailed analysis derived from the application of these tools over multiple spatial and temporal scales. Chapter 1 provides a general background to the research topic. Chapter 2 introduces a novel physical expression of evapotranspiration that shows how land-atmosphere interactions control evapotranspiration. The proposed physical expression is evaluated using field observations and a global-scale evapotranspiration product. Chapter 3 focuses on climatic controls on evapotranspiration, which is also known as potential evaporation. In this chapter, a scientific debate regarding the trend of the potential evaporation is addressed by extending the land-atmosphere coupling theory introduced in Chapter 2. To this end, field-scale observations, watershed-scale observations, and climate simulations are used to assess model performance and to evaluate trends of potential evaporation. Chapter 4 derives a physically-based evapotranspiration model that requires only readily obtainable meteorological information. This new approach is evaluated using field-scale observations around the globe. Finally, Chapter 5 provides the overall conclusions from the research detailed in the preceding chapters. Overall, this thesis improves the estimation of evapotranspiration by minimizing empirical parameters required for modeling purposes, and by advancing our understanding of how land-atmosphere interactions control terrestrial evapotranspiration. In particular, the results suggest that the near-surface atmosphere should be understood as a reflection of the land surface dryness instead of as an atmospheric demand for soil moisture that is independent of surface conditions. This perspective underlies the models presented in this thesis, and by extension will facilitate more accurate predictions of evapotranspiration.

description: We introduce a novel algorithm, $\textit{COD}$ -- Compact Opacity Distribution, for shape reconstruction of a celestial body that has been observed to occult a star, using the photometric time-series observations of the occultation. $\textit{COD}$ finds a solution to the light-curve inversion problem for an optically thick occulter having an approximately convex shape, together with an estimate of its size, impact parameter and velocity, relative to the occulted star. The algorithm is based on an optimization scheme that uses topological constraints and an objective function for the geometry of the occulter. The constraints of the problem follow linear relations, which enable the use of linear programming optimization as the mathematical framework. Multiple tests of the algorithm were performed, all of which resulted in high correlations between the simulated and obtained shapes of the occulting objects, with errors within $5\%$ in their projected velocities and horizontal sizes, and within $0.1$ in their impact parameters. These tests include a video of a solar eclipse by Phobos, as seen by NASA's Curiosity rover, which was collapsed into its corresponding light curve and reconstructed afterwards. We applied $\textit{COD}$ to the mysterious case of VVV-WIT-08 -- a single deep occultation ($\sim 96 \%$) of a giant star lasting for over 200 days. The analysis, which did not assume any specific shape of the occulter, suggested an object with a projected opacity distribution resembling an ellipse with an eccentricity of $\sim 0.5$, tilted at $\sim 30$ degrees relative to the direction of motion, with a semi-minor axis similar to the stellar radius.

description: Thermal noise of optical cavities limits the accuracy of many experiments on precision laser spectroscopy and interferometry. The study of the physical properties of this noise opens opportunities for the creation of more stable cavities, reduction of phase noise of optical radiation, and performance of accurate optical studies. The paper proposes a method of partial recording of TEM00 mode thermal noise of a Fabry-Perot cavity using two "probe" modes of higher order. The method allows partial compensation of noise in the fundamental mode. Mathematical modeling is performed, which confirms the efficiency of the method.

Nesse processo, a artista evidencia o ato pictórico realizado sob os comandos e inscrições algorítmicas das interfaces digitais. Entre suas influências estão o artista britânico David Hockney, o brasileiro Iberê Camargo, o expressionista Van Gogh e o pintor de retratos, Lucian Freud. Das inúmeras produções e experimentações, a artista apresenta cinco imagens decorrentes de seu trabalho mais recente (2016/2017) realizado especificamente com as ferramentas digitais, a saber, o pincel, lápis, tubo de tinta e espátula, disponibilizadas pelo software ArtRage, com o auxílio de uma mesa digitalizadora. Nas imagens, a artista traz retratos de pessoas sem nome e inexistentes. Embora a materialidade não seja a tinta, a tela ou o pincel tal como a conhecemos, tais experimentações revelam um pouco sobre sua história e trajetória, na tentativa de compreender a si mesma e aos outros. Outros que deixam seus rastros pelo caminho, com suas fragilidades, pensamentos, sentimentos, próprios do ser humano.

description: Lors de la modélisation thermique ou thermo-mécanique différentes approches peuvent être choisies pour la partie thermique. Parmi ces approches, l’approche thermique tout simplement. Cet approche bien que très simplificatrices par rapport aux autres approche Thermo-hydrique ou thermo-hydro-chimique, reste très pertinente dans certains cas. Dans le cadre de nos travaux de caractérisation du comportement global des structures en béton armé au feu, l’approche thermique simple a été choisie pour alimenter le modèle thermo-mécanique par les résultats thermiques. Les auteurs sont amenés à traiter une variété de béton dont les compositions physico-chimiques ne seraient pas finement connues. Sachant que l’Eurocode 2 nous fournis que peu d’information par rapport aux caractéristiques thermiques du béton Il serait opportun d’établir une base de donnée plus exhaustive et détaillée ainsi que bien documentée pour choisir des courbes de chaleur massique et de conductivité thermique plus adaptées que celles figurant dans l’Eucocode 2 (EC 2). Ce travail est fait dans le but d’éliminer l’erreur commise pendant le calcul thermique ou du moins, d’arriver à limiter l’erreur en température. Cette dernière erreur s’accumule au fil des calculs thermiques puis thermomécaniques et peut entrainer d’autres erreurs considérables dans le cadre d’une étude de stabilité structurelle.

description: L’utilisation des polymères renforcés de fibre de carbone dans la réparation est une technique largement rependue. On retrouve dans la littérature de nombreuses études ayant démontrées l’intérêt des renforts par PRFC dans le renforcement de structure face aux sollicitations sismiques. Cette étude cherche à étudier l’impact d’un renfort sur le comportement d’une liaison voile/dalle en béton armé. L’étude s’articule autour d’une campagne expérimentale menée sur 4 spécimens renforcés. L’objectif est d’étudier le comportement et l’endommagement de divers spécimens face à un chargement cyclique alterné. Le comportement des différentes configurations de renfort est comparé à celui de l’essai témoin. Les résultats montrent un gain de résistance pouvant atteindre 70% et de raideur de l’ordre de 60%. Les configurations de renfort n’ont que peu d’impact sur la ductilité des liaisons. Les tests montrent également que les solutions de liaisons renforcées ne dissipent pas plus d’énergie que le témoin.

description: Ce travail poursuit l’objectif de comprendre les conditions d’apprentissage qui permettent d’articuler l’autonomie des élèves ainsi que leur motivation. En effet, notre mission est que les élèves du primaire puissent acquérir de nouveaux savoirs en sciences, tout en étant autonomes et motivés. Pour ce faire, nous avons testé 4 variables (ateliers liés/non liés, ateliers autonomes/dirigés, ordre des ateliers autonomes/dirigés et type d’atelier dirigé) au travers de 4 situations didactiques différentes au sein d’une séquence en sciences de la nature. La première séance était composée d’un atelier dirigé et un atelier autonome non liés prenant place simultanément. En effet, les élèves les ont vécus dans un ordre chronologique inverse : un groupe a commencé par l’atelier autonome (situation 1) et l’autre par l’atelier dirigé (situation 2). La deuxième séance comportait également un atelier autonome et un atelier dirigé, mais cette fois-ci liés. Cependant, l’atelier dirigé n’était pas le même pour les deux groupes d’élèves. Un premier groupe a commencé par l’atelier dirigé 1, qui était une vidéo à visionner (situation 3) et l’autre partie de la classe a commencé par l’atelier autonome (situation 4) avant de vivre l’atelier dirigé 2 basé sur l’utilisation d’attelles. En ce sens, nous avons fait varier les modalités de travail, ce qui nous a permis d’analyser l’impact des diverses postures de l’enseignante (expert, guide, accompagnateur) et par conséquent, celles des élèves. Nous avons effectué une analyse a posteriori de la séquence que nous avons proposée aux élèves, en retranscrivant les interactions langagières entre les élèves et entre ceux-ci et l’enseignante par le biais d’enregistrements vidéo et vocaux. Nous avons alors produit une grille qui nous a permis d’analyser les phénomènes de dévolution, de motivation et de partage des responsabilités. Les résultats obtenus nous montrent que pour placer un élève en situation autonome, tout en garantissant sa motivation, il est préférable de proposer des tâches liées entre elles dans un premier temps. De plus, il est primordial qu’une médiation pédagogique faite par l’enseignante, entre l’élève et le savoir soit réussie. Finalement, nous avons pris conscience de l’impact des différentes postures enseignantes sur l’autonomie et la motivation des élèves. Selon sa posture, l’enseignante dévolue en partageant la responsabilité des apprentissages avec les élèves (topogenèse).

description: In this work, fern-leaf-like BiVO4 was used to photocatalytically reduce Cr6+ in water. Nanosized BiVO4 displayed bandgap energy and specific surface area of 2.49 eV and 5.65 m2 g−1, respectively. Metallic Au nanoparticles were deposited on the BiVO4 to increase the photocatalytic performance. To optimize the reaction conditions, the sacrificial agents methanol, ethanol, formic acid, dimethyl sulfoxide, and KI were tested, while different catalyst dosages and Au loadings were assessed. The best sacrificial agent was formic acid, which was used at an optimal concentration of 0.01 mol L−1. The complete removal of Cr6+ was attained after 90 min of visible light irradiation using a catalyst dosage of 1.5 g L−1. Depositing metallic Au nanoparticles barely improved the photocatalytic performance, thus unmodified BiVO4 was used to remove Cr6+ in tap water. The matrix effect slowed the photocatalytic process, and the complete removal of Cr6+ was achieved in 120 min. Cr3+ and Cr6+ species were precipitated on the catalyst surface at the end of the photocatalytic process; still, BiVO4 displayed high stability after three reaction cycles.

description: Cette contribution résume une application expérimentale basée sur la détection de la signature vibratoire d’un portique en acier par la technique d’identification appelée « input-output ». Pour cela, un test sur table vibrante est réalisé sur la structure réduite sous une excitation dynamique harmonique. La réponse dynamique est mesurée par des accéléromètres uni-axiaux répartis sur le portique étudié. L’analyse des résultats, par le logiciel MATLAB, a permis l’identification des caractéristiques dynamiques (périodes, fréquences et modes propres de vibration) de la structure. Un modèle tridimensionnel en éléments finis est ensuite construit et calibré en fonction des caractéristiques dynamiques préalablement identifiées. La comparaison entre le résultat expérimentalement détecté et celui numériquement construit a permis la validation de la technique d’identification proposée.

Exploring complexity in changing practices of care : a mixed methods inquiry into rights, relations, and knowledge in protected area conservation

description: Commonly described as the cornerstone of conservation, protected areas contribute immeasurably to supporting flourishing ecosystems and human wellbeing, and are crucial tools to address the accelerating biodiversity crisis. Yet conventional exclusionary approaches have frequently proven ineffective and inequitable. Accordingly, there is a pressing need for conservation actors to make decisions considering diverse knowledge and values, under conditions of high uncertainty. This dissertation is concerned with the nature of these decisions as they are unfolding in practice, and their entanglements with structures of power, patterns of change, and diverse ways of knowing the human and other-than-human landscape. At multiple scales of decision-making –– conservation planners, community forest managers, and household resource users –– I investigate how institutional arrangements, evidentiary norms, and human-environment relationships affect stewardship. The second chapter develops a novel approach using document analysis and survey methods to assess how the Nature Conservancy of Canada applies multiple types of evidence in conservation planning, identifying evidence gaps and barriers to effective engagement with Indigenous knowledges. The subsequent empirical chapters focus on three related aspects of environmental governance in van panchayat community forests in a high mountain valley in Uttarakhand, India. Chapter 3 introduces the case study, describing how forest councils navigate their legal and customary rights and responsibilities to manage van panchayats for conservation and livelihood benefits. In the same region, the fourth chapter applies a mental models analysis approach to interview data, to illustrate complexities and patterns in how local forest managers are perceiving and responding to intersecting dimensions of change. The fifth and final empirical chapter reports on qualitative and quantitative analyses of a household survey on human-wildlife relations in the same community forests, finding that institutional responsibilities and ethics of care contribute meaningfully to norms of coexistence with wild animals despite persistent conflict. These inquiries apply a range of methodological approaches to advance theories of environmental governance in political ecology, knowledge co-production, and the human dimensions of conservation. In doing so, this work highlights the highly complex, context-specific, and changing ways in which stewarding actors care for protected areas in practice, and identifies potential pathways to support these efforts.

description: Dans le cas général, la prise en compte du comportement d’un matériau jusqu’à la ruine permet une conception plus optimisée en utilisant des modèles beaucoup plus prédictifs. Dans le cadre de notre étude, nous présentons quelques résultats de la démarche modélisation analytique menée pour analyser le comportement de dalles en béton non armées, renforcées sur la face extérieure par des patchs composites en liège, de dimensions variées sous l'effet d'un chargement vertical progressif excentré, avec un pas de (1/3)L’ et (2/3)L’ par rapport au centre de gravité de la dalle. A cet effet plusieurs dimensions des patchs composites sont considérées, à savoir :(6×4) cm2, (12x8) cm2 et (18x12) cm2. Les résultats montrent que les dimensions du patch composite ont une influence directe sur la déformée avant la rupture.

description: The problem of determining if a military unit has correctly understood an order and is properly executing on it is one that has bedeviled military planners throughout history. The advent of advanced language models such as OpenAI's GPT-series offers new possibilities for addressing this problem. This paper presents a mechanism to harness the narrative output of large language models and produce diagrams or "maps" of the relationships that are latent in the weights of such models as the GPT-3. The resulting "Neural Narrative Maps" (NNMs), are intended to provide insight into the organization of information, opinion, and belief in the model, which in turn provide means to understand intent and response in the context of physical distance. This paper discusses the problem of mapping information spaces in general, and then presents a concrete implementation of this concept in the context of OpenAI's GPT-3 language model for determining if a subordinate is following a commander's intent in a high-risk situation. The subordinate's locations within the NNM allow a novel capability to evaluate the intent of the subordinate with respect to the commander. We show that is is possible not only to determine if they are nearby in narrative space, but also how they are oriented, and what "trajectory" they are on. Our results show that our method is able to produce high-quality maps, and demonstrate new ways of evaluating intent more generally.

description: Impact dynamics are crucial for estimating the growth patterns of NFT projects by tracking the diffusion and decay of their relative appeal among stakeholders. Machine learning methods for impact dynamics analysis are incomprehensible and rigid in terms of their interpretability and transparency, whilst stakeholders require interactive tools for informed decision-making. Nevertheless, developing such a tool is challenging due to the substantial, heterogeneous NFT transaction data and the requirements for flexible, customized interactions. To this end, we integrate intuitive visualizations to unveil the impact dynamics of NFT projects. We first conduct a formative study and summarize analysis criteria, including substitution mechanisms, impact attributes, and design requirements from stakeholders. Next, we propose the Minimal Substitution Model to simulate substitutive systems of NFT projects that can be feasibly represented as node-link graphs. Particularly, we utilize attribute-aware techniques to embed the project status and stakeholder behaviors in the layout design. Accordingly, we develop a multi-view visual analytics system, namely NFTracer, allowing interactive analysis of impact dynamics in NFT transactions. We demonstrate the informativeness, effectiveness, and usability of NFTracer by performing two case studies with domain experts and one user study with stakeholders. The studies suggest that NFT projects featuring a higher degree of similarity are more likely to substitute each other. The impact of NFT projects within substitutive systems is contingent upon the degree of stakeholders' influx and projects' freshness.
