Gebäude auf Abbruch? The digital archive of Kant’s Opus postumum
Creators: name: Helbig, Daniela
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2020

description: Over two hundred years after Immanuel Kant’s death, the first full, critical, and digital edition of his last manuscript is currently being completed by the Berlin-Brandenburgische Akademie der Wissenschaften. This edition stands in institutional continuity with Wilhelm Dilthey’s monumental Akademieausgabe of Kant’s writings that was grounded in Dilthey’s lastingly influential concept of the national, literary-philosophical archive. The new edition showcases Kant’s dynamic writing process as a matter of investigation in its own right. As I argue here, it brings into view the constitutive role of the archive for both texts and interpretative practices. A historical perspective that links the legacy of the Akademieausgabe with the digital edition of the Opus postumum highlights the changing role of the archive in emphasising or de-emphasising the manuscript’s resistance to certain appropriations and stylisations of Kant as a thinker.

Interminable readings. Jacques Derrida between archive and dissemination
Creators: name: Vitale, Francesco
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2020

description: The paper seeks to outline the relationship between Geschlecht III and Derrida’s published texts devoted to the mark «Geschlecht» in order to detect the general strategy followed by Jacques Derrida into the construction of his archive during his lifetime. Indeed, we suppose that his archive has to be build in accordance with his deconstructive statements about the classical conception of the archive: a totalizing closure of a textual production able to trace it back to the unity of an ideal identity. In particular, the paper aims to focus on a passage at the end of Jacques Derrida’s Geschlecht III, where the question of the animal in Heidegger comes in the foreground and in a way that is slightly different from what we already know through Derrida’s published Works and could impose a re-reading of its «entire» work.

Silence, in the Archives: Derrida’s Other Marx(s)
Creators: name: Mercier, Thomas Clément
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico

description: The idea that Derrida kept silent on Marx before the publication of Spectres de Marx, in 1993, has become a commonplace in Derrida studies and in the history of Marxism and French 20th century political thought. This idea has often been accompanied by a certain representation of the relationship (or absence thereof) between deconstruction and dialectical materialism, and fed the legend of deconstruction’s «apoliticism» – at least before what some have called Derrida’s «ethicopolitical turn», usually dated in the early 1990s. Against this narrative, this essay analyzes Derrida’s notorious «silence on Marx» before Specters of Marx from the perspective of the archives. Archival research transforms the narrative: Derrida’s «silence on Marx» was only «relative». Beyond the scene of publications, archives reveal another scene: multiple engagements with Marx and Marxist thought, marked and remarked in many archival documents – more particularly in a series of early seminar notes from the 1960s and 1970s. How does this archival scene transform our interpretation of Derrida’s «silence»?

description: We have compiled a sample of 14 of the optically brightest radio-quiet quasars ($m_{i}$~$\le$~17.5 and $z$~$\ge$~1.9) in the Sloan Digital Sky Survey Data Release 5 quasar catalog that have C IV mini-BALs present in their spectra. X-ray data for 12 of the objects were obtained via a Chandra snapshot survey using ACIS-S, while data for the other two quasars were obtained from archival XMM-Newton observations. Joint X-ray spectral analysis shows the mini-BAL quasars have a similar average power-law photon index ($Γ\approx1.9$) and level of intrinsic absorption ($N_H \lesssim 8\times 10^{21} \ {\rm cm}^{-2}$) as non-BMB (neither BAL nor mini-BAL) quasars. Mini-BAL quasars are more similar to non-BMB quasars than to BAL quasars in their distribution of relative X-ray brightness (assessed with $Δα_{\rm ox}$). Relative colors indicate mild dust reddening in the optical spectra of mini-BAL quasars. Significant correlations between $Δα_{\rm ox}$ and UV absorption properties are confirmed for a sample of 56 sources combining mini-BAL and BAL quasars with high signal-to-noise ratio rest-frame UV spectra, which generally supports models in which X-ray absorption is important in enabling driving of the UV absorption-line wind. We also propose alternative parametrizations of the UV absorption properties of mini-BAL and BAL quasars, which may better describe the broad absorption troughs in some respects.

description: The human genome sequence database contains DNA sequences very like those of mycoplasma molds. It appears such moulds infect not only molecular Biology laboratories but were picked up by experimenters from contaminated samples and inserted into GenBank as if they were human. At least one mouldy EST (Expressed Sequence Tag) has transferred from public databases to commercial tools (Affymetrix HG-U133 plus 2.0 microarrays). We report a second example (DA466599) and suggest there is a need to clean up genomic databases but fear current tools will be inadequate to catch genes which have jumped the silicon barrier.

Baudelaire Laboratory. Brief History of a Project by Walter Benjamin
Creators: name: Montanelli, Marina
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2020

description: The article intends to retrace, from a historical-philological point of view, the main steps of Walter Benjamin’s unfinished research and works, conducted during his later years, dedicated to Charles Baudelaire. Setting Benjamin’s translation of the Ta-bleaux parisiens as the first result of his interest for the poet, the text delves into the composition process of The Arcades Project, from which the idea of a book on Baudelaire then takes shape. The article examines the crucial stages of this second project’s development through the correspondence between Benjamin and Theodor Adorno and Max Horkheimer especially: from the 1935 exposé for The Arcades Project to The Paris of the Second Empire in Baudelaire, to the 1939 essay On some Motifs in Baudelaire. The focus is set, in particular, on the dialectical-constructive method that guides Benjamin in the composition both of the Passagen-Werk as of the Baudelaire-Buch and the essays. Finally, the article looks back over the transmission history of the project on Baudelaire, intimately bound to the one of the Passagenarbeit: the vicissitudes and findings of various manuscripts, of which the complete restitution of the Kritische Gesamtausgabe is soon expected. Therefore, the peculiar relationship between philology and philosophy of Benjamin’s experimental method is then examined further in depth; the configuration of the research object’s monadic structure according to a historical perspective, albeit in the context of a work that remained unfinished.

The Autographic Stance. Benjamin, Wittgenstein and the Re-Shaping of the Philosophical Opus. About Manuscripts, Fragments, Schemes, Sketches and Annotations

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2020

description: Starting from the peculiar tension between figure and writing in Walter Benjamin’s philosophical thought, my contribution aims to define the relevance of manuscripts, schemes, fragments and annotations for the definition of philosophical textuality. Analyzing Benjamin’s writings belonging to this genre (for example, the preparatory works for the essay dedicated to Goethe’s Elective Affinities or for the essay on Kafka), as well as the fragmentary observations belonging to Novalis’ Allgemeines Brouillon and Nietzsche’s Posthumous Fragments, the processual dimension of philosophical thinking will be emphasized. In this theoretical context the processual moment of textuality can be put in tension with the moment defined by the work in its insular completeness. Finally, one wonders if the most appropriate form of philosophical thought in our era of digital production and transmission of knowledge does not really lie in the flow dynamics of textuality. In conclusion, it will remain to be clarified how the autographic moment of philosophy can be thought of in the digital age of knowledge. To this last extent, a good example would be eventually given by Walter Benjamin’s archive in Berlin that contains in fully digitalized form both edited texts and manuscripts.

description: We present results from the multi-wavelength study of XMMU J1230.3+1339 at z ~ 1. We analyze deep multi-band wide-field images from the Large Binocular Telescope, multi-object spectroscopy observations from VLT, as well as space-based serendipitous observations, from the GALEX and Chandra X-ray observatories. We apply a Bayesian photometric redshift code to derive the redshifts using the FUV, NUV and the deep U, B, V, r, i, z data. We achieve an accuracy of $\triangle z/(1+z)$ = 0.07 (0.04) and the fraction of catastrophic outliers is $η$ = 13 (0)%, when using all (secure) spectroscopic data, respectively. The i - z against z colour-magnitude relation of the photo-z members shows a tight red-sequence with a zero point of 0.935 mag, and slope equal to -0.027. We observe evidence for a truncation at the faint end of the red-cluster-sequence and the Butcher-Oemler effect, finding a fraction of blue galaxies $f_b \approx$ 0.5. Further we conduct a weak lensing analysis of the deep 26' $\times$ 26' r-band LBC image. The observed shear is fitted with a Single-Isothermal-Sphere and a Navarro-Frenk-White model to obtain the velocity dispersion and the model parameters, respectively. Our best fit values are, for the velocity dispersion $σ_{SIS}$ = 1308 $\pm$ 284, concentration parameter c = 4.0$^{+14}_{-2}$ and scale radius r$_{s}$ = 345$^{+50}_{-57}$ kpc. Combining our mass estimates from the kinematic, X-ray and weak lensing analyses we obtain a total cluster mass of $M^{tot}_{200}$ = (4.56 $\pm$ 2.3) $\times$ 10$^{14}$ M$_{\sun}$. This study demonstrates the feasibility of ground based weak lensing measurements of galaxy clusters up to z ~ 1.

Accordingly, the manifestly covariant, dual symmetric and gauge invariant two potential theory of generalized electromagnetic fields of dyons has been developed consistently from U(1)\times U(1) gauge symmetry. Corresponding field equations and equation of motion are derived from Lagrangian formulation adopted for U(1)\times U(1) gauge symmetry for the justification of two four potentials of dyons.

description: We study a class of Markovian systems of $N$ elements taking values in $[0,1]$ that evolve in discrete time $t$ via randomized replacement rules based on the ranks of the elements. These rank-driven processes are inspired by variants of the Bak--Sneppen model of evolution, in which the system represents an evolutionary 'fitness landscape' and which is famous as a simple model displaying self-organized criticality. Our main results are concerned with long-time large-$N$ asymptotics for the general model in which, at each time step, $K$ randomly chosen elements are discarded and replaced by independent $U[0,1]$ variables, where the ranks of the elements to be replaced are chosen, independently at each time step, according to a distribution $κ_N$ on $\{1,2,...,N\}^K$. Our main results are that, under appropriate conditions on $κ_N$, the system exhibits threshold behaviour at $s^* \in [0,1]$, where $s^*$ is a function of $κ_N$, and the marginal distribution of a randomly selected element converges to $U[s^*, 1]$ as $t \to \infty$ and $N \to \infty$. Of this class of models, results in the literature have previously been given for special cases only, namely the 'mean-field' or 'random neighbour' Bak--Sneppen model. Our proofs avoid the heuristic arguments of some of the previous work and use Foster--Lyapunov ideas. Our results extend existing results and establish their natural, more general context. We derive some more specialized results for the particular case where K=2. One of our technical tools is a result on convergence of stationary distributions for families of uniformly ergodic Markov chains on increasing state-spaces, which may be of independent interest.

A study of cellulosic biomass size reduction
Creators: name: Jafari Naimi, Ladan
Publisher: name: University of British Columbia
Year: 2016

description: Size reduction is an essential operation for preparing biomass for the production of pellets, biofuels and bioproducts. Size reduction ranks second in terms of energy consumption after drying in a pelleting operation. The major challenge in sizing and operating a grinder is the difficulty in predicting the performance of a grinder and the quality of product due to the variability in structure and composition of the biomass. As a result, grinders are often over- designed to handle a wide range of biomass species, leading to disproportionate equipment size and operating costs. This research investigated factors influencing the power requirement for grinding biomass and developed mechanistic model equations to predict energy input to a grinder to achieve a targeted particle size. Two softwood species and three hardwood species were ground in a knife mill and/or a hammer mill. The experimental data consisted of power inputs, mass flow rates, and particle size reduction ratios. The well-known mechanistic model equations: Rittinger, Kick, and Bond, which relate energy input to particle size reduction, were evaluated and the Rittinger equation was found to give the best prediction of the experimental data. Douglas-fir consumed the least specific energy of grinding, 132-178 kJ kg‐¹, followed by aspen, 197-232 kJ kg‐¹, pine, 201-263 kJ kg‐¹, and poplar, 252-297 kJ kg‐¹. Specific surface area (m² kg‐¹) created was largest for aspen and smallest for Douglas-fir. Correspondingly, Douglas-fir consumed the least specific energy and aspen, with the largest specific surface area created, required the highest specific energy. These data suggest that the specific energy has a direct relation with the total surface area created as a result of size reduction, as captured by the Rittinger equation. Ground Douglas-fir and willow were also pelletized in a single pelletization unit. The combined grinding/densification energy input decreased with increasing particle size. The properties most significantly affecting the grinding energy consumption based on the comparison of the Rittinger’s constant, kR, were lignin content, particle density, and fibre length. Woody biomass of a higher lignin content, lower particle density, and longer fibre length requires more energy input to be ground to a targeted size.
Kernel-Phase in Fizeau Inteferometry

description: The detection of high contrast companions at small angular separation appears feasible in conventional direct images using the self-calibration properties of interferometric observable quantities. The friendly notion of closure-phase, which is key to the recent observational successes of non-redundant aperture masking interferometry used with Adaptive Optics, appears to be one example of a wide family of observable quantities that are not contaminated by phase-noise. In the high-Strehl regime, soon to be available thanks to the coming generation of extreme Adaptive Optics systems on ground based telescopes, and already available from space, closure-phase like information can be extracted from any direct image, even taken with a redundant aperture. These new phase-noise immune observable quantities, called kernel-phases, are determined a-priori from the knowledge of the geometry of the pupil only. Re-analysis of archive data acquired with the Hubble Space Telescope NICMOS instrument, using this new kernel-phase algorithm demonstrates the power of the method as it clearly detects and locates with milli-arcsecond precision a known companion to a star at angular separation less than the diffraction limit.

The aim of the present paper is to obtain an index formula for such operators in terms of topological invariants of the manifold and of the symbol of the operator. The symbol in this situation is an element of a certain crossed product. We express the index as the pairing of the class in K-theory defined by the symbol and the Todd class in periodic cyclic cohomology of the crossed product.

Convergence-Optimal Quantizer Design of Distributed Contraction-based Iterative Algorithms with Quantized Message Passing

description: In this paper, we study the convergence behavior of distributed iterative algorithms with quantized message passing. We first introduce general iterative function evaluation algorithms for solving fixed point problems distributively. We then analyze the convergence of the distributed algorithms, e.g. Jacobi scheme and Gauss-Seidel scheme, under the quantized message passing. Based on the closed-form convergence performance derived, we propose two quantizer designs, namely the time invariant convergence-optimal quantizer (TICOQ) and the time varying convergence-optimal quantizer (TVCOQ), to minimize the effect of the quantization error on the convergence. We also study the tradeoff between the convergence error and message passing overhead for both TICOQ and TVCOQ. As an example, we apply the TICOQ and TVCOQ designs to the iterative waterfilling algorithm of MIMO interference game.

description: Homogeneous, nearly-isotropic Bianchi cosmological models are considered. Their time evolution is expressed as a complete set of non-interacting linear modes on top of a Friedmann-Robertson-Walker background model. This connects the extensive literature on Bianchi models with the more commonly-adopted perturbation approach to general relativistic cosmological evolution. Expressions for the relevant metric perturbations in familiar coordinate systems can be extracted straightforwardly. Amongst other possibilities, this allows for future analysis of anisotropic matter sources in a more general geometry than usually attempted. We discuss the geometric mechanisms by which maximal symmetry is broken in the context of these models, shedding light on the origin of different Bianchi types. When all relevant length-scales are super-horizon, the simplest Bianchi I models emerge (in which anisotropic quantities appear parallel transported). Finally we highlight the existence of arbitrarily long near-isotropic epochs in models of general Bianchi type (including those without an exact isotropic limit).

description: Students’ school-related well-being (SWB) is of vital importance. Nevertheless, it is unclear how SWB develops in late adolescence, especially among students in high-achieving environments and which factors are associated with it. Based on a longitudinal dataset (T1: Grade 11, T2: Grade 12), we analyzed how SWB (school satisfaction, academic self-concept, stress experience, exam anxiety, peer satisfaction) develops and whether psychological needs (autonomy, competence, relatedness) and achievement pressure from teachers and parents were related to the development. 1,286 students from high-achieving high schools (46.7% female, MageT1 = 16.40) answered sociodemographic questions and questions about key variables. From T1 to T2, particularly students’ stress experience and peer satisfaction declined. Need fulfilment and perceived achievement pressure was related to changes. Implications for research and practice are discussed.

description: The Gas Slit Camera (GSC) is an X-ray instrument on the MAXI (Monitor of All-sky X-ray Image) mission on the International Space Station. It is designed to scan the entire sky every 92-minute orbital period in the 2--30 keV band and to achieve the highest sensitivity among the X-ray all-sky monitors ever flown so far. The GSC employs large-area position-sensitive proportional counters with the total detector area of 5350 cm$^2$. The on-board data processor has functions to format telemetry data as well as to control the high voltage of the proportional counters to protect them from the particle irradiation. The paper describes the instruments, on-board data processing, telemetry data formats, and performance specifications expected from the ground calibration tests.

description: It is largely agreed that many coronal loops---those observed at a temperature of about 1 MK--- are bundles of unresolved strands that are heated by storms of impulsive nanoflares. The nature of coronal heating in hotter loops and in the very important but largely ignored diffuse component of active regions is much less clear. Are these regions also heated impulsively, or is the heating quasi steady? The spectacular new data from the Atmospheric Imaging Assembly (AIA) telescopes on the Solar Dynamics Observatory (SDO) offer an excellent opportunity to address this question. We analyze the light curves of coronal loops and the diffuse corona in 6 different AIA channels and compare them with the predicted light curves from theoretical models. Light curves in the different AIA channels reach their peak intensities with predictable orderings as a function the nanoflare storm properties. We show that while some sets of light curves exhibit clear evidence of cooling after nanoflare storms, other cases are less straightforward to interpret. Complications arise because of line-of-sight integration through many different structures, the broadband nature of the AIA channels, and because physical properties can change substantially depending on the magnitude of the energy release. Nevertheless, the light curves exhibit predictable and understandable patterns consistent with impulsive nanoflare heating.

description: In this thesis, we discuss recent progress on higher dimensional analogues to the Analyst’s Travelling Salesman Theorem (TST) of Peter Jones. The TST characterizes subsets of rectifiable curves in the plane, via a multiscale sum of β-numbers. These β-numbers measure how far a set E deviates from a straight line at a particular scale and location. This idea was extended by Okikiolu to subsets of Euclidean space and by Schul to subsets of Hilbert space. In 2018, Azzam and Schul introduced a variant of the Jones β-number. With this, they, and separately Villa, proved similar results for higher dimensional subsets of Euclidean space. In particular, Villa characterizes the lower regular subsets of a certain class of d-dimensional surfaces, first introduced in a 2004 paper of David. We prove an analogous result for arbitrary subsets of Euclidean space, we do not need to assume lower regularity. To do this, we introduce a new d-dimensional variant of the Jones β-number that is defined for any set in Euclidean space. A significant portion of this thesis is dedicated to studying the properties of this β-number.

description: Using three kinds of labor skills training methods (expert team training, recruit training and local agricultural extension center training), based on enterprise planting and farmer planting, this paper analyzes the impact of training methods on the development of potato industry, such as yield, income and planting extension. The results show that the expert team training, recruit training and labor skills training of local agricultural extension center can significantly improve the labor quality and skills, and increase the yield and income of winter potatoes. The expert team training, recruit training and local agricultural extension center training can lift growers out of poverty and improve the willingness of people to plant and extend. The winter potato industry has become one of the pillar industries to shake off poverty and become rich, increasing local economic benefits. Through labor skills training, the winter potato industry has become one of the main industries to improve the quality of the local people and increase economic income, promoting the local people to shake off poverty and become well-off.

description: We present a strong-lensing analysis of the galaxy cluster MS 1358.4+6245 ($z=0.33$), in deep 6-band ACS/HST imaging. In addition to the well-studied system at $z=4.92$, our modelling method uncovers 19 new multiply-lensed images so that a total of 23 images and their redshifts are used to accurately constrain the inner mass distribution. We derive a relatively shallow inner mass profile, $d\log Σ/d\log r\simeq -0.33 \pm0.05$ ($r<200$ kpc), with a much higher magnification than estimated previously by models constrained only by the $z=4.92$ system. Using these many new images we can apply a non-parametric adaptive-grid method, which also yields a shallow mass profile without prior assumptions, strengthening our conclusions. The total magnification of the $z_s=4.92$ galaxy is high, about a $\sim100\times$ over its four images, so that the inferred source size, luminosity and star-formation rate are about $\sim5\times$ smaller than previous estimates, corresponding to a dwarf-sized galaxy of radius $\simeq1$ kpc. A detailed image of the interior morphology of the source is generated with a high effective resolution of only $\simeq$50 pc, thanks to the high magnification and to the declining angular diameter distance above $z\sim1.5$ for the standard cosmology, so that this image apparently represents the best resolved object known at high redshift.

Methyl metabolism in obesity-related cardiac remodeling

description: Cardiovascular disease (CVD) is the second leading cause of death in Canada. Obesity is a well-established risk factor for CVD and its prevalence has increased dramatically across the globe during recent decades. In the setting of obesity, excess lipid accumulation in the heart leads to changes in cardiac function and metabolism of CVD. The molecular mechanisms contributing to these obesity-related CVDs are not well understood, and may involve DNA methylation. Methylation of DNA is a post-replication modification that provides ‘marks’ in the genome, such that genes are set to be transcriptionally activated or silenced. DNA methyltransferases are responsible for the methylation of DNA and use S-adenosylmethionine (AdoMet) as the methyl donor. The metabolism of methyl groups and the production of AdoMet involve three interrelated pathways: folate cycle, methionine cycle, and transsulfuration pathway. As such, disturbances in methyl metabolism could change DNA methylation patterns in the heart and be involved in the pathogenesis of CVD. The objective of this thesis was to test the general hypothesis that disturbances in methyl metabolism contributes to obesity-related cardiovascular pathology. C57BL/6J mice with (+/-) and without (+/+) a heterozygous targeted disruption of the gene for cystathionine-beta-synthase (CBS), an enzyme required for the transsulfuration pathway, were used to disrupt methyl metabolism. At weaning, mice were fed either a control diet or a high-fat diet (HFD, 60% energy from fat) to induce excess adiposity (obesity). Studies in the thesis revealed three major findings. First, disturbances in methyl metabolism enhanced cardiac lipotoxicity associated with diet-induced obesity. Second,disturbances in methyl metabolism altered cardiac energy metabolism and function associated with obesity-related cardiac remodeling. Third, disturbances in methyl metabolism contributed to a tissue-specific relationship between ‘methylation capacity’ (AdoMet/AdoHcy ratio), DNA methylation, and gene expression in Cbs +/- mice. In summary, these data revealed a unique role for CBS in cardiac fatty acid metabolism, possibly contributing to the pathology of obesity-related cardiac remodeling. These findings also provide first time evidence of disturbances in methyl metabolism and the functional consequences as it pertains to DNA methylation, regulation of gene expression, and cardiac remodeling in mice with diet-induced obesity.

description: The fluid models mentioned in the title are studied in a modified approach, based on two formulas for the mass function. All characteristics of the fluid are expressed through a master potential, satisfying an ordinary second order differential equation. Different constraints are imposed on this core of relations, finding new solutions and deriving the classical results for perfect fluids as particular cases. All charged anisotropic solutions, all conformally flat and all uniform density solutions are found. A large class of solutions with linear equation among the two pressures is derived, including the case of vanishing tangential pressure. The mechanism responsible for the appearance of equation of state is elucidated.

description: In northern China's agro-pastoral ecotone, there are conflicts between agricultural industry and ecological construction resource competition, and also problems urgently to be solved for economic growth and sustainable ecological improvement. Taking the development concept of “lucid waters and lush mountains being mountains of gold and silver” as the guiding principle of prioritizing ecological and green development, this paper studied the strategies for prioritizing ecological construction with consideration of economic development of agricultural industry from the perspective of opportunity cost. Through the analysis of opportunity cost, externality, and Pareto optimal theory, and using the calculation method of the unit equivalent factor value of terrestrial ecological service function, this paper calculated the ecological service value of forest, grassland, and farmland. It found that the ecological value of forest and grassland per unit area was greater than the ecological value of agricultural industry. This indicates that the opportunity cost of farmland for ecological construction was less than that of agricultural industry. Based on the theoretical and quantitative analysis, it came up with recommendations for establishing a comprehensive system for prioritizing ecological construction with consideration of agricultural industry development and establishing and improving the incentive mechanism of ecological construction.

description: This repository provides the code and data required to replicate the analysis presented in the paper accepted to the 18th International Conference on Cooperative and Human Aspects of Software Engineering (CHASE 2025) titled "More Than Code: Technical and Emotional Dynamics in Solidity's Development."Background: Solidity is the primary programming language used for developing smart contracts on Ethereum, representing a new generation of programming languages developed entirely in open environments.Objective: This longitudinal case study examines contribution patterns and emotional dynamics within the Solidity GitHub repository over a ten-year period (2014-2024).Method: We developed a contribution index combining metrics from developer activities (commits, pull requests, comments, and temporal engagement) and applied emotion detection to study communication patterns in a decade-long dataset of developer interactions.Results: The top 1% of contributors are responsible for around 85% of project contributions, yet the project exhibits dual paths to prominence: early contributors established technical foundations through code, while later contributors achieved influence through reviews and discussions. Emotional patterns show transitions from initial curiosity and confusion to eventual approval and gratitude.Conclusion: The project's recognition of diverse contribution types and evolving emotional dynamics enables sustainable growth despite concentrated contributions, demonstrating how open-source languages can evolve while maintaining both technical rigor and community engagement.Preprint: https://smartbridgelab.co.uk/wp-content/uploads/2025/02/chase25_vaccargiu-1.pdf
