description: We have investigated the effect of initial mass segregation on the runaway merging of stars. The evolution of multi-mass, dense star clusters was followed by means of direct N-body simulations of up to 131.072 stars. All clusters started from King models with dimensionless central potentials of 3.0 <= W_0 <= 9.0. Initial mass segregation was realized by varying the minimum mass of a certain fraction of stars whose either (1) distances were closest to the cluster center or (2) total energies were lowest. The second case is more favorable to promote the runaway merging of stars by creating a high-mass core of massive, low-energy stars. Initial mass segregation could decrease the central relaxation time and thus help the formation of a high-mass core. However, we found that initial mass segregation does not help the runaway stellar merger to happen if the overall mass density profile is kept constant. This is due to the fact that the collision rate of stars is not increased due to initial mass segregation. Our simulations show that initial mass segregation is not sufficient to allow runaway merging of stars to occur in clusters with central densities typical for star clusters in the Milky Way.

A practical model of bronchogenic carcinoma in Camm-Hartley guinea pigs and Golden Syrian hamsters
Creators: name: Bainbridge, Terry Cyril
Publisher: name: University of British Columbia
Year: 2010

description: Bronchogenic carcinoma (lung cancer) is a major source of morbidity and mortality in industrialized nations. Although bronchogenic carcinoma is largely a preventable neoplasm, it will undoubtedly remain a major medical concern throughout this century, and considerable effort needs to be directed towards its early detection, establishing effective treatment, and understanding the neoplastic process. The objective of this study was to develop a practical and reliable model of localized bronchogenic carcinoma in laboratory rodents. This was done by impregnating cotton threads with the potent carcinogen, benzo(a)pyrene (BP). These BP-impregnated threads were then coated with a silicone rubber sheath to control the release of BP from the threads. The prepared threads were sewn around four cartilage rings in the ventral tracheal wall of guinea pigs and hamsters. The animals were sacrificed periodically, and two histopathologists graded the tracheal epithelium adjacent to the thread. The first experiment consisted of 94 Camm-Hartley guinea pigs: 48 experimental animals with BP-impregnated threads and 46 control animals with non-impregnated threads. The second experiment consisted of 70 Golden Syrian hamsters: 54 experimental and 16 control animals. The data showed that the implantation of the thread in the trachea induced a regenerative hyperplasia of the epithelium, and that the BP initiated carcinogenesis. Squamous metaplasia and progressive intraepithelial neoplasia (IEN) was evident prior to the development of squamous cell carcinoma (CA). In the experimental guinea pigs, only one guinea pig developed an invasive CA at 265 days. In the experimental hamsters, the first CA was seen at 55 days and after 120 days, 65% of the animals showed histopathologic evidence of CA. Most of the hamsters with CA also had spindle cell tumors in the tracheal stroma. The control hamsters and guinea pigs did not develop IEN, and the mature respiratory epithelium was reconstituted. We conclude that this method produced localized, readily accessible preneoplastic and neoplastic lesion in the trachea of hamsters, and to a lesser extent in guinea pigs. The model should prove useful in the study of tumor ultrastructure, the immunologic response to cancer, and the relationship of diet to cancer.

description: In a recent paper, it has been suggested that the controllability of a diffusively coupled complex network, subject to localized feedback loops at some of its vertices, can be assessed by means of a Master Stability Function approach, where the network controllability is defined in terms of the spectral properties of an appropriate Laplacian matrix. Following that approach, a comparison study is reported here among different network topologies in terms of their controllability. The effects of heterogeneity in the degree distribution, as well as of degree correlation and community structure, are discussed.

The present analysis relies on the most recent SNe Ia events, being model independent. Our study might suggest that event horizon is not a physical boundary from the point of view of thermodynamics.

description: Upper bounds for rates of convergence of posterior distributions associated to Gaussian process priors are obtained by van der Vaart and van Zanten in [14] and expressed in terms of a concentration function involving the Reproducing Kernel Hilbert Space of the Gaussian prior. Here lower-bound counterparts are obtained. As a corollary, we obtain the precise rate of convergence of posteriors for Gaussian priors in various settings. Additionally, we extend the upper-bound results of [14] about Riemann-Liouville priors to a continuous family of parameters.

description: We elaborate the generalizations of the approach to gauge-invariant deformations of the gauge theories developed in our previous work [1]. In the given paper we construct the exact transformations defying the gauge-invariant deformed theory on the base of initial gauge theory with irreducible open gauge algebra. Like in [1], for the theories with open gauge algebras these transformations are the shifts of the initial gauge fields $A \rightarrow A+h(A)$, with the help of the arbitrary and in general non-local functions $h(A)$. The results are applied to study the quantum aspects of the deformed theories. We derive the exact relation between the quantum effective actions for the above classical theories, where one is obtained from another with the help of the deformation.

description: The Bogoliubov recursion is a particular procedure appearing in the process of renormalization in perturbative quantum field theory. It provides convergent expressions for otherwise divergent integrals. We develop here a theory of functional identities for noncommutative Rota-Baxter algebras which is shown to encode, among others, this process in the context of Connes-Kreimer's Hopf algebra of renormalization. Our results generalize the seminal Cartier-Rota theory of classical Spitzer-type identities for commutative Rota-Baxter algebras. In the classical, commutative, case, these identities can be understood as deriving from the theory of symmetric functions. Here, we show that an analogous property holds for noncommutative Rota-Baxter algebras. That is, we show that functional identities in the noncommutative setting can be derived from the theory of noncommutative symmetric functions. Lie idempotents, and particularly the Dynkin idempotent play a crucial role in the process. Their action on the pro-unipotent groups such as those of perturbative renormalization is described in detail along the way.

Hydrostatic pressure study of pure and doped La1-xRxAgSb2 (R = Ce, Nd) charge-density-wave compounds

description: The intermetallic compound LaAgSb2 displays two charge-density-wave (CDW) transitions, which were detected with measurements of electrical resistivity (rho), magnetic susceptibility, and X-ray scattering; the upper transition takes place at T1 approx. 210 K, and it is accompanied by a large anomaly in rho(T), whereas the lower transition is marked by a much more subtle anomaly at T2 approx. 185 K. We studied the effect of hydrostatic pressure (P) on the formation of the upper CDW state in pure and doped La1-xRxAgSb2 (R = Ce, Nd) compounds, by means of measurements of rho(T) for P < 23 kbar. We found that the hydrostatic pressure, as well as the chemical pressure introduced by the partial substitution of the smaller Ce and Nd ions for La, result in the suppression of the CDW ground state, e.g. the reduction of the ordering temperature T1. The values of dT1/dP are approx. 2-4 times higher for the Ce-doped samples as compared to pure LaAgSb2, or even La0.75Nd0.25AgSb2 Nd-doped with a comparable T1 (P=0). This increased sensitivity to pressure may be due to increasing Ce- hybridization under pressure. The magnetic ordering temperature of the cerium-doped compounds is also reduced by pressure, and the high pressure behavior of the Ce-doped samples is dominated by Kondo impurity scattering.

description: Starting from a Born-Oppenheimer decomposition of the Wheeler-DeWitt equation for the quantum cosmology of the matter-gravity system, we have performed a Wigner-Weyl transformation and obtained equations involving a Wigner function for the scale factor and its conjugate momentum. This has allowed us to study in more detail than previously the approach to the classical limit of gravitation and the way time emerges in such a limit. To lowest order we reproduce the Friedmann equation and the previously obtained equation for the evolution of matter. We also obtain expressions for higher order corrections to the semi-classical limit.

description: There are a few prominent practices for conducting reviews of academic literature, including searching for specific keywords on Google Scholar or checking citations from some initial seed paper(s). These approaches serve a critical purpose for academic literature reviews, yet there remain challenges in identifying relevant literature when similar work may utilize different terminology (e.g., mixed-initiative visual analytics papers may not use the same terminology as papers on model-steering, yet the two topics are relevant to one another). In this paper, we introduce a system, VitaLITy, intended to complement existing practices. In particular, VitaLITy promotes serendipitous discovery of relevant literature using transformer language models, allowing users to find semantically similar papers in a word embedding space given (1) a list of input paper(s) or (2) a working abstract. VitaLITy visualizes this document-level embedding space in an interactive 2-D scatterplot using dimension reduction. VitaLITy also summarizes meta information about the document corpus or search query, including keywords and co-authors, and allows users to save and export papers for use in a literature review. We present qualitative findings from an evaluation of VitaLITy, suggesting it can be a promising complementary technique for conducting academic literature reviews. Furthermore, we contribute data from 38 popular data visualization publication venues in VitaLITy, and we provide scrapers for the open-source community to continue to grow the list of supported venues.

description: It is known that oscillatory domain-wall (DW) motions in soft magnetic thin-film nanostripes above the Walker critical field lead to a remarkable reduction in the average DW velocities. In a much-higher-field region beyond the velocity-breakdown regime, however, the DW velocities have been found to increase in response to a further increase of the applied field. We report on the physical origin and detailed mechanism of this unexpected behavior. We associate the mechanism with the serial dynamic processes of the nucleation of vortex-antivortex (V-AV) pairs inside the stripe or at its edges, the non-linear gyrotropic motions of Vs and AVs, and their annihilation process. The present results imply that a two-dimensional soliton model is required for adequate interpretation of DW motions in the linear- and oscillatory-DW-motion regimes as well as in the beyond-velocity-breakdown regime.

description: Attosecond pulses can be used to initiate and control electron dynamics on a sub-femtosecond time scale. The first step in this process occurs when an atom absorbs an ultraviolet photon leading to the formation of an attosecond electron wave packet (EWP). Until now, attosecond pulses have been used to create free EWPs in the continuum, where they quickly disperse. In this paper we use a train of attosecond pulses, synchronized to an infrared (IR) laser field, to create a series of EWPs that are below the ionization threshold in helium. We show that the ionization probability then becomes a function of the delay between the IR and attosecond fields. Calculations that reproduce the experimental results demonstrate that this ionization control results from interference between transiently bound EWPs created by different pulses in the train. In this way, we are able to observe, for the first time, wave packet interference in a strongly driven atomic system.

description: We demonstrate that the standard Stueckelberg-modified Proca theory (i.e. a massive Abelian 1-form theory) respects the classical gauge and corresponding quantum (anti-)BRST symmetry transformations in any arbitrary dimension of spacetime within the framework of Becchi-Rouet-Stora-Tyutin (BRST) formalism. We further show that the Stueckelberg formalism gets modified in the two (1+1)-dimensions of spacetime due to a couple of discrete duality symmetries in the theory which turn out to be responsible for the existence of the nilpotent (anti-)co-BRST symmetry transformations corresponding to the nilpotent (anti-)BRST symmetry transformations of our theory. These nilpotent symmetries exist together in the modified version of the two (1+1)-dimensional (2D) Proca theory. We provide the mathematical basis for the modification of the Stueckelberg-technique, the existence of the discrete duality as well as the continuous (anti-)co-BRST symmetry transformations in the 2D modified version of Proca theory.

description: Computer simulations were done of the mean square displacement (MSD) of tracer particles in colloidal gels formed by diffusion or reaction limited aggregation of hard spheres. The diffusion coefficient was found to be determined by the volume fraction accessible to the spherical tracers ($ϕ_a$) independent of the gel structure or the tracer size. In all cases, critical slowing down was observed at $ϕ_a\approx 0.03$ and was characterized by the same scaling laws reported earlier for tracer diffusion in a Lorentz gas. Strong heterogeneity of the MSD was observed at small $ϕ_a$ and was related to the size distribution of pores.

description: This thesis investigates the performance of Chinese commercial banks by evaluating their efficiency and productivity. Beginning with cost efficiency analysis of Chinese commercial banks over the time period 2002 to 2014. The thesis then analyses the efficiency and productivity of regional banks, specifically urban commercial banks. Based on geographical characteristics of regional banks, the spatial parameters are added in the production function in order to capture spatial spillovers. A new spatial total factor productivity index to measure productivity is introduced. The results indicate that the efficiency of Chinese commercial banks increased in the pre- and post-crisis period but dropped during the financial crisis. In addition, the results suggest that the joint-stock and regional banks are more efficient than other type of banks in China. Another notable result is the significant positive spatial relationship in the production process of the Chinese regional banks. Overall productivity has increased from 2013 to 2016, which is mainly improved by the return to scale changing.

description: The present Deliverable "ECS curricula, the training modules and the materials" is a first draft of how EdiCitNet can spread the idea of the Edible City with its Edible City Solutions (ECS) through different educational formats and above all how EdiCitNet can anchor it deeply in our increasingly urbanised world. The ECS curricula follow the principles of inclusive communities of knowledge and practice. We present the general approach of the development of knowledge covered by the ECS curricula: I) ECS Governance,
 II) Economic valuation of ECS
 III) ECS as Ecological Systems and
 IV) Socio-cultural impact of ECS and different learning formats (i.e. standard, global, local, online and special formats). Furthermore, we defined a three-step roadmap to anchor ECS curricula in a sustainable form beyond the duration of the EdiCitNet project - including evaluation loops to critically revise and optimize ECS curricula. We drafted the ECS curricula, ECS training modules and materials. The final delivery of ECS curricula, training modules and materials, into which all knowledge collected and developed during the project period can be incorporated, will be available with Deliverable 7.6 towards the end of the project in July 2023.
Effects of Serial Polydrug Use on the Rewarding and Aversive Effects of the Novel Synthetic Cathinone Eutylone

description: Drugs of abuse have rewarding and aversive effects that in balance mediate drug intake.Although such effects have been reported with a variety of abused drugs, recent work with the synthetic cathinones (a class of new psychoactive substances [NPS]) has reported similar dual properties in this group as well. As individual synthetic cathinones become scheduled and regulated by the Drug Enforcement Administration (DEA), new ones regularly are produced and distributed. One such compound is eutylone, a novel third-generation synthetic cathinone. To date, its affective properties (and abuse potential) remain unknown, and the goal of the following experiments was to begin the characterization of these effects and how they may be impacted by drug history (one factor known to affect reward/aversion for other drugs of abuse). Prior to assessing these effects in a design that allows for the concurrent examination of both affective properties, Experiment 1 tested the ability of C57BL/6 mice to display conditioned taste avoidance (CTA) and conditioned place preference (CPP) in a combined CTA/CPP design induced by the structurally related compound methylone for which such effects have been independently reported. Following this demonstration, eutylone was assessed for its ability to induce CTA (aversive effect) and CPP (rewarding effect) and for their relationship in the combined design (Experiment 2). Following this, the effects of drug history (i.e., cocaine or 3,4- methylenedioxymethamphetamine [MDMA]; Experiment 3) on eutylone’s affective properties were investigated to model human users of these compounds who frequently engage in serial polydrug use. Experiment 1 revealed that independent of sex, mice displayed significant methylone-induced CTA and CPP and these two effects were not related. Experiment 2 demonstrated that eutylone, like methylone, produced dose-dependent aversive and rewarding effects, and again these endpoints were unrelated. Finally, Experiment 3 reported that preexposure to cocaine and MDMA differentially impacted the aversive effects of eutylone (MDMA > cocaine) and did not impact eutylone-induced place preference. Taken together, these data indicate that eutylone, like other synthetic cathinones, has co-occurring, independent rewarding and aversive effects that may contribute to its abuse potential and that these effects are differentially impacted by drug history. Although these studies begin the characterization of eutylone, future studies should examine the impact of factors on these affective properties and its eventual reinforcing effects (i.e., intravenous self-administration [IVSA]) to predict its use and abuse liability.

Diffusion covariation and co-jumps in bidimensional asset price processes with stochastic volatility and infinite activity Levy jumps

description: In this paper we consider two processes driven by diffusions and jumps. The jump components are Levy processes and they can both have finite activity and infinite activity. Given discrete observations we estimate the covariation between the two diffusion parts and the co-jumps. The detection of the co-jumps allows to gain insight in the dependence structure of the jump components and has important applications in finance. Our estimators are based on a threshold principle allowing to isolate the jumps. This work follows Gobbi and Mancini (2006) where the asymptotic normality for the estimator of the covariation, with convergence speed given by the squared root of h, was obtained when the jump components have finite activity. Here we show that the speed is the squared root of h only when the activity of the jump components is moderate.

description: In this paper we report on the spectral evolution of 4U 1608-522 performed as part of the long Galactic Bulge monitoring with INTEGRAL. The data set include the April 2005 outburst. BeppoSAX archival data (two observations, in 1998 and 2000) have been also analysed and compared with the INTEGRAL ones. Three different spectral states have been identified from the hard Color-Intensity diagram derived from INTEGRAL: the canonical Hard and Soft as well as an Intermediate state. The hard state spectrum is well described by a weak black body component plus a Comptonised plasma component with high electron temperature (kTe~60 keV) extending up to 200 keV without any additional cut-off. The soft spectra are characterized by a cold Comptonised plasma (kTe= 2-3 keV, and 7 keV for the intermediate state) and a strong disk black body component. A reflection component, indicating reflection of the X-ray radiation from the accretion disc, is also present in the soft state revealed by BeppoSAX in 1998. The 2000 BeppoSAX observation revealed the source in quiescent state modelled by a neutron star atmosphere (assuming a neutron star with radius 10 km and mass 1.4 Msun) with an effective temperature, kTeff of 0.1 keV plus a power law component with Gamma~3 detected for the first time for this source. This spectrum can also be modelled with a simple black body compatible with emission originating from a small fraction of the NS surface of radius of 0.4 km.

description: We minimally extend the SM with a Z$_2$ symmetric potential containing a single scalar field, serving as our inflaton with a quartic self-coupling. In the model we have symmetry breaking in both sectors, and with the addition of an inflaton-Higgs portal, the Universe is able to efficiently reheat via 2-2 inflaton-Higgs scattering. Assuming that the Universe with a positive cosmological constant should be metastable, only one particular symmetry breaking pattern in the vacuum is possible, without the need to finely-tune the Higgs' quartic self-coupling. Inflaton with masses in the range $O(10^{-3})\leq m_χ\leq m_{h}$ and mixing angles that span $θ_{m}^{2}=O(10^{-11}-10^{-2})$ evade all current cosmological, experimental and stability constraints required for a metastable EW vacuum. Upgraded particle physics experiments may be able to probe the parameter space with $θ_{m}^{2}\geq O(10^{-4})$, where we would observe trilinear Higgs couplings suppressed by up to $2\%$ compared to the SM value. However to access the parameter space of very weakly-coupled inflaton, we rely on the proposals to build experiments that target the hidden sector.

description: We reanalyze the data on the in-plane far infrared conductivity of underdoped orthoII YBa$_{2}$Cu$_{3}$O$_{6.50}$ (YBCO$_{6.50}$) in terms of a model in which a pseudogap opens on part of the Fermi surface with the remaining ungaped piece proportional to the temperature. The motivation for our model comes from recent angle-resolved photoemission spectroscopy data in underdoped Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ (Bi-2212), which have revealed the existence of arcs on the Fermi surface. We find the optical data to be consistent with arc formation. In addition we find some evidence that the electronic states lost below the pseudogap energy $Δ_{pg}$ are recovered in the energy region immediately above it at least for temperatures near $T_c$.

description: We present an extension to the Poisson-Boltzmann model where the dipolar features of solvent molecules are taken explicitly into account. The formulation is derived at mean-field level and can be extended to any order in a systematic expansion. It is applied to a two-plate system with oppositely charged surfaces. The ion distribution and profiles in the dipolar order parameter are calculated and can result in a large correction to the inter-plate pressure.

Probabilistic analysis of three-player symmetric quantum games played using the Einstein-Podolsky-Rosen-Bohm setting

description: This paper extends our probabilistic framework for two-player quantum games to the mutliplayer case, while giving a unified perspective for both classical and quantum games. Considering joint probabilities in the standard Einstein-Podolsky-Rosen-Bohm (EPR-Bohm) setting for three observers, we use this setting in order to play general three-player non-cooperative symmetric games. We analyze how the peculiar non-factorizable joint probabilities provided by the EPR-Bohm setting can change the outcome of a game, while requiring that the quantum game attains a classical interpretation for factorizable joint probabilities. In this framework, our analysis of the three-player generalized Prisoner's Dilemma (PD) shows that the players can indeed escape from the classical outcome of the game, because of non-factorizable joint probabilities that the EPR setting can provide. This surprising result for three-player PD contrasts strikingly with our earlier result for two-player PD, played in the same framework, in which even non-factorizable joint probabilities do not result in escaping from the classical consequence of the game.

description: This talk discusses the Research Software Directory: a kind of content management system tailored to research software. The idea is that institutes for whom research software is an important output, can run their own instance of the Research Software Directory, thereby improving the findability, citability, and reproducibility of their software packages, while qualitatively illustrating impact. The system periodically collects data from GitHub, Zenodo, and Zotero. Those data are combined with a description of the software, which developers provide via a web form. The combined data is then used to create a 'product page': a visually attractive, easy-to-consume website that presents a given software package along with its scientific and social context. Product pages contain metadata in schema.org format, which helps to improve the findability and ranking by search engines. Furthermore, product pages offer reference manager files in BibTeX, RIS, and EndNote for download, thus promoting easy, accurate citation of the software. Both the schema.org metadata and the reference files are themselves derived from citation data written in Citation File Format, which are harvested from GitHub. Finally, a minimal OAI-PMH interface was recently added to the system, such that archiving services can automatically harvest the contents of a Research Software Directory.
Nonvanishing vector fields on orbifolds

description: We introduce a complete obstruction to the existence of nonvanishing vector fields on a closed orbifold $Q$. Motivated by the inertia orbifold, the space of multi-sectors, and the generalized orbifold Euler characteristics, we construct for each finitely generated group $Γ$ an orbifold called the space of $Γ$-sectors of $Q$. The obstruction occurs as the Euler-Satake characteristics of the $Γ$-sectors for an appropriate choice of $Γ$; in the case that $Q$ is oriented, this obstruction is expressed as a cohomology class, the $Γ$-Euler-Satake class. We also acquire a complete obstruction in the case that $Q$ is compact with boundary and in the case that $Q$ is an open suborbifold of a closed orbifold.

Power-law cosmology in Weyl-type $f(Q,T)$ gravity

description: Gravity is attributed to the spacetime curvature in classical General Relativity (GR). But, other equivalent formulation or representations of GR, such as torsion or non-metricity have altered the perception. We consider the Weyl-type $f(Q, T)$ gravity, where $Q$ represents the non-metricity and $T$ is the trace of energy momentum temsor, in which the vector field $ω_μ$ determines the non-metricity $Q_{μνα}$ of the spacetime. In this work, we employ the well-motivated $f(Q, T)= αQ+ \fracβ{6k^{2}} T$, where $α$ and $β$ are the model parameters. Furthermore, we assume that the universe is dominated by the pressure-free matter, i.e. the case of dust ($p=0$). We obtain the solution of field equations similar to a power-law in Hubble parameter $H(z)$. We investigate the cosmological implications of the model by constraining the model parameter $α$ and $β$ using the recent 57 points Hubble data and 1048 points Pantheon supernovae data. To study various dark energy models, we use statefinder analysis to address the current cosmic acceleration. We also observe the $Om$ diagnostic describing various phases of the universe. Finally, it is seen that the solution which mimics the power-law fits well with the Pantheon data better than the Hubble data.

Optical bistability at low light level due to collective atomic recoil

description: We demonstrate optical nonlinearities due to the interaction of weak optical fields with the collective motion of a strongly dispersive ultracold gas. The combination of a recoil-induced resonance (RIR) in the high gain regime and optical waveguiding within the dispersive medium enables us to achieve a collective atomic cooperativity of $275 \pm 50$ even in the absence of a cavity. As a result, we observe optical bistability at input powers as low as 20 pW. The present scheme allows for dynamic optical control of the dispersive properties of the ultracold gas using very weak pulses of light. The experimental observations are in good agreement with a theoretical model.

description: This document delivers the results of Task 7.2 “Development of the Marketplace application” of the Social Sciences and Humanities Open Cloud (SSHOC) project funded by the European Commission under Grant Agreement #823782. Its main purpose is to describe the actual implementation of the SSH Open Marketplace application on the background of the system specification (delivered in 2019 as D7.1 System Specification - SSH Open Marketplace). The SSH Open Marketplace is a discovery portal which pools and contextualises resources for Social Sciences and Humanities research communities: tools, services, training materials, datasets and workflows. The Marketplace highlights and showcases solutions and research practices for every step of the SSH research data life cycle. Based on an agile methodology and an iterative process of releases, the implementation of the SSH Open Marketplace is carefully described here, and this deliverable represents a companion to the final release of the application (in December 2021). Three other complementary WP7 deliverables published between September and December 2021 are also documenting and supporting the final release: D7.3 Marketplace Interoperability; D7.4 Marketplace Data population & curation and D7.5 Marketplace Governance. Following the requirements engineering process and the first iterations of the data model and system architecture presented in the System Specification, this implementation report describes the methodology used to ensure the quality of the SSH Open Marketplace software, and presents the latest iteration of the data model and system architecture supported by the rationales for the implementation choices. Key components and features, as well as other aspects of the system like its configuration, deployment or its API are described giving a technical insight into the creation of this discovery portal. Embedded in the European Open Science Cloud (EOSC) ecosystem, the SSH Open Marketplace has also been developed to contribute to the resources discoverability layer of the EOSC and to ensure, thanks to its user-friendly interface, an entry door to the EOSC for social scientists and humanists.
