description: Finite difference discretization schemes preserving a subgroup of the maximal Lie invariance group of the one-dimensional linear heat equation are determined. These invariant schemes are constructed using the invariantization procedure for non-invariant schemes of the heat equation in computational coordinates. We propose a new methodology for handling moving discretization grids which are generally indispensable for invariant numerical schemes. The idea is to use the invariant grid equation, which determines the locations of the grid point at the next time level only for a single integration step and then to project the obtained solution to the regular grid using invariant interpolation schemes. This guarantees that the scheme is invariant and allows one to work on the simpler stationary grids. The discretization errors of the invariant schemes are established and their convergence rates are estimated. Numerical tests are carried out to shed some light on the numerical properties of invariant discretization schemes using the proposed evolution-projection strategy.

description: We perform a frequentist analysis of q^2-dependent B-> K*(->Kpi)ll angular observables at large recoil, aiming at bridging the gap between current theoretical analyses and the actual experimental measurements. We focus on the most appropriate set of observables to measure and on the role of the q^2-binning. We highlight the importance of the observables P_i exhibiting a limited sensitivity to soft form factors for the search for New Physics contributions. We compute predictions for these binned observables in the Standard Model, and we compare them with their experimental determination extracted from recent LHCb data. Analyzing b->s and b->sll transitions within four different New Physics scenarios, we identify several New Physics benchmark points which can be discriminated through the measurement of P_i observables with a fine q^2-binning. We emphasise the importance (and risks) of using observables with (un)suppressed dependence on soft form factors for the search of New Physics, which we illustrate by the different size of hadronic uncertainties attached to two related observables (P_1 and S_3). We illustrate how the q^2-dependent angular observables measured in several bins can help to unravel New Physics contributions to B-> K*(->Kpi)ll, and show the extraordinary constraining power that the clean observables will have in the near future. We provide semi-numerical expressions for these observables as functions of the relevant Wilson coefficients at the low scale.

description: Titan's moment of inertia, calculated assuming hydrostatic equilibrium from gravity field data obtained during the Cassini-Huygens mission, implies an internal mass distribution that may be incompatible with complete differentiation. This suggests that Titan may have a mixed ice/rock core, possibly consistent with slow accretion in a gas-starved disk, which may initially spare Titan from widespread ice melting and subsequent differentiation. A partially differentiated Titan, however, must still efficiently remove radiogenic heat over geologic time. We argue that compositional heterogeneity in the major Saturnian satellites indicates that Titan formed from planetesimals with disparate densities. The resulting compositional anomalies would quickly redistribute to form a vertical density gradient that would oppose thermal convection. We use elements of the theory of double-diffusive convection to create a parameterized model for the thermal evolution of ice/rock mixtures with a stabilizing compositional gradient. Simulations are performed for a wide range of initial conditions to account for large uncertainties in material properties and accretionary processes. Ultimately, for realistic density gradients, double-diffusive convection in the ice/rock interior can delay, but not prevent, ice melting and differentiation, even if a substantial fraction of potassium is leached from the rock component. Consequently, Titan is not partially differentiated.

description: This deliverable produced in the scope of WP3's D3.1 "Requirements to Situation Awareness and SA Model". D3.1 describes methods for finding the information requirements that first responders need to achieve a level of situation awareness, in order to develop disaster emergencies. Situation Awareness (SA) is the accuracy with which people perceive, understand and anticipate changes in their environment that are relevant to achieving operational goals. But first, a Knowledge Management System is required, in order to capture, develop, share and use organisational knowledge to finally enable SA, as Emergency management requires a Knowledge Management System that can adaptively respond to the uncertainties inherent to crisis and manmade disasters. The Knowledge Management System requires components, both human and hardware, that must pursue a variety of operational goals (time of response, time of deployment, rescue victims etc.).
 The focus of the deliverable D3.1 is the definition of the technological requirements of the Knowledge Management functionality in order to enable situation awareness, more efficient context-aware data sharing and presentation to the emergency responding actors, and subsequently more efficient decision-making support.
Fermionic superoperators for zero-temperature non-linear transport: real-time perturbation theory and renormalization group for Anderson quantum dots

description: We study the transport through a strongly interacting Anderson quantum dot at zero-temperature using the real-time renormalization group (RT-RG) in the framework of a kinetic equation for the reduced density operator. We further develop the general finite temperature real-time transport formalism by introducing field superoperators that obey fermionic statistics. This direct second quantization in Liouville-Fock space strongly simplifies the construction of operators and superoperators which transform irreducibly under the Anderson-model symmetry transformations. The fermionic field superoperators naturally arise from the univalence (fermion-parity) superselection rule for the total system. Expressed in these field superoperators, the causal structure of the perturbation theory for the effective time-evolution superoperator-kernel becomes explicit. The causal structure also implies the existence of a fermion-parity protected eigenvector of the exact Liouvillian, explaining a recently reported result on adiabatic driving [Phys. Rev. B 85, 075301 (2012)] and generalizing it to arbitrary order in the tunnel coupling. Furthermore, in the WBL the causal representation exponentially reduces the number of diagrams for the time-evolution kernel. We perform a complete 2-loop RG analysis at finite voltage and magnetic field, while systematically accounting for the dependence on both the quantum dot and reservoir frequencies. Using the second quantization in Liouville-space and symmetry restrictions we obtain analytical RT-RG equations with an efficient numerical solution and we extensively study the model parameter space, excluding the Kondo regime. The incorporated renormalization effects result in an enhancement of the inelastic cotunneling peak. Moreover, we find a tunnel-induced non-linearity of the stability diagrams at finite voltage, both in the SET and ICT regime.

description: Using the method of maximal cuts, we construct the complete D-dimensional integrand of the five-loop four-point amplitude of N = 4 super-Yang-Mills theory, including nonplanar contributions. In the critical dimension where this amplitude becomes ultraviolet divergent, we present a compact explicit expression for the nonvanishing ultraviolet divergence in terms of three vacuum integrals. This construction provides a crucial step towards obtaining the corresponding amplitude of N = 8 supergravity useful for resolving the general ultraviolet behavior of supergravity theories.

description: Recently evidence for gamma ray lines at energies of approximately 111 and 128 GeV has been found in Fermi-LAT data from the center of the galaxy and from unassociated point sources. Many explanations in terms of dark matter particle pairs annihilating to gamma gamma and gamma Z have been suggested, but these typically require very large couplings or mysterious coincidences in the masses of several new particles to fit the signal strength. We propose a simple novel explanation in which dark matter is part of a multiplet of new states which all have mass near 260 GeV as a result of symmetry. Two dark matter particles annihilate to a pair of neutral particles in this multiplet which subsequently decay to gamma gamma and gamma Z. For example, one may have a triplet of pseudo-Nambu-Goldstone bosons, charged pions and a neutral pion, where the charged pions are stabilized by their charge under a new U(1) symmetry and the slightly lighter neutral pion state decays to gamma gamma and gamma Z. The symmetry structure of such a model explains the near degeneracy in masses needed for the resulting photons to have a line-like shape and the large observed flux. The tunable lifetime of the neutral state allows such models to go unseen at direct detection or collider experiments that can constrain most other explanations. However, nucleosynthesis constraints on the neutral pion lifetime fix a minimum necessary coupling between the new multiplet and the Standard Model. The spectrum is predicted to be not a line but a box with a width of order a few GeV, smaller than but on the order of the Fermi-LAT resolution.

Abstract delle autrici:
Background and Aims: Euroflora is one of the main floral events in Europe. For the visibility to a national and international public, it is also considered one of the most important events all over the Ligurian area. Polyclinic Hospital San Martino, in collaboration with Unige Dietetics Degree Course, Agricultural Institute of Marsano, Marco Polo and Bergese Hotel Institutes of Genoa, decided to take part in this event setting up a stand to promote health and food education, based on concept "good food and good health".Methods: The 80 mq of stand, decorated with edible flowering plants and aromatic herbs belonging to Mediterranean scrub by agricultural school students, hosted a synergistic vegetable garden. The Dietetics degree course in collaboration with Hotel Institutes prepared informative material: a brochure showing nutritional properties of plants and flowers present in the stand and a "health" recipe book that suggests the use of these plants, with a view to food sustainability. The activity at Euroflora was an integral part of the internship of the students of the Degree Course who carried out food education activities, also submitting the Medi-lite questionnaire to the participants and providing personalized indications in relation to the score obtained.Results: 884 people visited the Polyclinic stand, completed the Medi-lite questionnaire and received personalized indications to improve their eating habits. From the preliminary analysis of the questionnaires, the mean adherence score was 12 ± 2, significantly higher in women than in men (p=0.022). Analyzing the main components, we observed that the Medi-Lite items on the consumption of some products generated response clusters. Subjects who consume more meat, tend to eat more dairy products as well, so it could be index of a fattier diet. By contrast, subjects who consume more fish also consume more fruits and vegetables, with a trend to prefer healthier foods.Conclusion: Although the sample's adherence to the Mediterranean Diet score is good/moderate, initiatives such as Euroflora's "Good food and good health" could foster a synergistic action between the education world and the scientific world, in order to increase responsibility and awareness of citizens in compliance with correct eating habits in a non-healthcare setting.

description: We study coherent interaction of cosmic background neutrinos(CBNs) with matter of periodic structure. The mixing and small masses of neutrinos discovered in neutrino oscillation experiments indicate that CBNs which have very low energy today should be in mass states and can transform from one mass state to another in interaction with electrons in matter. We show that in a coherent scattering process a periodic matter structure designed to match the scale of the mass square difference of neutrinos can enhance the conversion of CBNs from one mass state to another. Energy of CBNs can be released in this scattering process and momentum transfer from CBNs to electrons in target matter can be obtained.

Abstract dell'autrice:
OPEN DATA a INFN-LNL per attività didatticheAlcuni anni fa (nel 2019), nel nostro laboratorio (INFN-LNL) è stato installato uno strumento didattico per misure sui raggi cosmici secondari: un telescopio a scintillatori plastici per la misura di flusso muonico a varie angolazioni dell'asse verticale.Lo strumento era stato costruito e collaudato da colleghi (INFN-PD) di sede all'Università di Padova, non lontana dal nostro laboratorio, ma comunque a circa 15 km di distanza.Per semplificare la fase di collaudo e controllo dello strumento nella sua nuova collocazione, noi del laboratorio INFN-LNL abbiamo predisposto un piccolo sistema di acquisizione dati dallo strumento e un set di procedure automatiche per trasferire i dati stessi in un sito web liberamente accessibile a noi e ai colleghi di Padova (in realtà del tutto aperto).La realizzazione di questo piccolo sistema "open data" per le misure sui muoni si è rivelato utile non soltanto per la fase di collaudo del sistema, dopo il suo trasferimento nella nuova sede, ma anche per varie altre finalità, ovvero:- il controllo del corretto funzionamento degli scintillatori e dell'elettronica di misura a distanza di settimane, mesi ed anni dalla sua prima installazione;- la verifica congiunta con i progettisti di Padova degli effetti ambientali a lungo termine sullo strumento (variazioni di luminosità ambientale, variazioni di temperatura stagionali);- la condivisione immediata dei dati di misura in occasione di eventi didattici nazionali (stage) e internazionali (International Cosmic Day)- l'immediato e possibile uso didattico dei dati da parte di studenti delle scuole superiori del territorio per analisi off-line durante attività di stage e/o orientamento attivo nella transizione scuola-università, organizzate anche con la supervisione dei colleghi di INFN-PD o direttamente dei docenti delle scuole.La modalità di accesso "open data" si è pertanto rivelata utile in una forma più ampia di quella prevista nella formulazione iniziale del progetto.Riteniamo inoltre che questo piccolo progetto sia stato un utile esempio della validità di queste metodologie di condivisione della conoscenza per tutti i numerosi studenti e docenti che ne hanno usufruito in questi anni.

description: In a recent paper by Beaton et al, it was proved that a model of self-avoiding walks on the honeycomb lattice, interacting with an impenetrable surface, undergoes an adsorption phase transition when the surface fugacity is $1+\sqrt{2}$. Their proof used a generalisation of an identity obtained by Duminil-Copin and Smirnov, and confirmed a conjecture of Batchelor and Yung. We consider a similar model of self-avoiding walk adsorption on the honeycomb lattice, but with the lattice rotated by $π/2$. For this model there also exists a conjecture for the critical surface fugacity, made in 1998 by Batchelor, Bennett-Wood and Owczarek. Using similar methods to Beaton et al, we prove that this is indeed the critical fugacity.

description: In this paper we address the problem of fast and fair transmission of flows in a router, which is a fundamental issue in networks like the Internet. We model the interaction between a TCP source and a bottleneck queue with the objective of designing optimal packet admission controls in the bottleneck queue. We focus on the relaxed version of the problem obtained by relaxing the fixed buffer capacity constraint that must be satisfied at all time epoch. The relaxation allows us to reduce the multi-flow problem into a family of single-flow problems, for which we can analyze both theoretically and numerically the existence of optimal control policies of special structure. In particular, we show that for a variety of parameters, TCP flows can be optimally controlled in routers by so-called index policies, but not always by threshold policies. We have also implemented index policies in Network Simulator-3 and tested in a simple topology their applicability in real networks. The simulation results show that the index policy covers a big range of desirable properties with respect to fairness between different versions of TCP models, across users with different round-trip-time and minimum buffer required to achieve full utility of the queue.

description: Transportation network companies (TNCs), often called “ridesharing” companies, operating today face a number of challenges in implementing ridesharing in their networks. The most substantial of these is efficiently identifying high quality ridesharing opportunities in an online operating environment. Optimal ridesharing, also known as the multiple vehicle pickup and delivery problem, is NP-hard and must be solved approximately using heuristics in an operating environment where riders almost never place reservations. The quantity and diversity of origin and destination locations within an urban environment also create challenges for quickly evaluating possible rideshares. Implementing pick-up and drop-off (PUDO) locations within the network can simplify ridesharing heuristics, allowing more accuracy in online ridesharing, but often it is unclear where PUDOs should be placed. This research proposes the use of clustering algorithms to abstract transportation networks as a solution to both problems. A ridesharing algorithm is proposed that uses a cluster adjacency index to quickly identify efficient ridesharing opportunities. The effectiveness of the ridesharing algorithm is examined using both K-means clustering, agnostic of network structure or congestion, and asynchronous fluid communities, a network clustering method that supports congestion weighting. The efficacy of the ridesharing algorithm is also assessed against different quantities of clusters and fleet sizes in the network. Node clustering in the urban core is used to identify well connected areas of the network that can be served by a single PUDO. PUDO placement methods within the cluster that are both conscious and agnostic of congestion and network structure are examined. This research concludes that properly calibrated network clustering methods with consideration of congestion are effective network abstractions that can easily be implemented in related research. The impact of congestion both in PUDO placement and in identifying communities served by a PUDO is not conclusively determined.

description: HIV evolves rapidly within individuals, allowing phylogenetic studies to infer histories of viral lineages on short time scales. Latent HIV sequences are an exception to this rapid evolution, as their transcriptional inactivity leads to negligible mutation rates compared with non-latent HIV lineages. This difference in mutation rates generates potential information about the times at which sequences entered the latent reservoir, providing insight into the dynamics of the latent reservoir. A Bayesian phylogenetic method is developed to infer integration times of latent HIV sequences. The method uses informative priors to incorporate biologically sensible bounds on inferences (such as requiring sequences to become latent before being sampled) that many existing methods lack. A new simulation method is also developed, based on widely used epidemiological models of within-host viral dynamics, and applied to evaluate the new method—showing that point estimates and credible intervals are often more accurate than existing methods. Accurate estimates of latent integration dates are crucial in relating integration times to key events during HIV infection, such as treatment initiation. The method is applied to publicly available sequence data from four HIV patients, providing new insights regarding the temporal pattern of latent integration.
When is a pure state of three qubits determined by its single-particle reduced density matrices?

description: Using techniques from symplectic geometry, we prove that a pure state of three qubits is up to local unitaries uniquely determined by its one-particle reduced density matrices exactly when their ordered spectra belong to the boundary of the, so called, Kirwan polytope. Otherwise, the states with given reduced density matrices are parameterized, up to local unitary equivalence, by two real variables. Given inevitable experimental imprecisions, this means that already for three qubits a pure quantum state can never be reconstructed from single-particle tomography. We moreover show that knowledge of the reduced density matrices is always sufficient if one is given the additional promise that the quantum state is not convertible to the Greenberger--Horne--Zeilinger (GHZ) state by stochastic local operations and classical communication (SLOCC), and discuss generalizations of our results to an arbitary number of qubits.

Nello scenario italiano, caratterizzato dalla mancanza di una normativa che riconosca un esplicito diritto di ripubblicazione in ambito scientifico, il progetto mira a: svolgere attività di advocacy a sostegno del riconoscimento del diritto di ripubblicazione; promuovere fra i ricercatori la consapevolezza delle possibilità di mantenere i diritti sulle proprie opere; focalizzare l'attenzione sui limiti dell'attuale legislazione nazionale.  A questo scopo, il progetto, da un lato, prevede una indagine sulla percezione da parte dei ricercatori CNR dei loro diritti nella pubblicazione dei risultati della ricerca e la messa a disposizione di materiali e strumenti informativi; dall'altro lato, pone le basi  per spingere verso un cambiamento delle politiche istituzionali di gestione dei diritti di pubblicazione nel contesto della scienza aperta.

description: The behaviour of a solid-liquid-gas system near the three-phase contact line is considered using a diffuse-interface model with no-slip at the solid and where the fluid phase is specified by a continuous density field. Relaxation of the classical approach of a sharp liquid-gas interface and careful examination of the asymptotic behaviour as the contact line is approached is shown to resolve the stress and pressure singularities associated with the moving contact line problem. Various features of the model are scrutinised, alongside extensions to incorporate slip, finite-time relaxation of the chemical potential, or a precursor film at the wall.

description: We calculate the annihilation decay widths of spin-singlet heavy quarkonia $h_c, h_b$ and $η_b$} into light hadrons with both QCD and relativistic corrections at order $O(α_{s}v^{2})$ in nonrelativistic QCD. With appropriate estimates for the long-distance matrix elements by using the potential model and operator evolution method, we find that our predictions of these decay widths are consistent with recent experimental measurements. We also find that the $O(α_{s}v^{2})$ corrections are small for $b\bar{b}$ states but substantial for $c\bar{c}$ states. In particular, the negative contribution of $O(α_{s}v^{2})$ correction to the $h_{c}$ decay can lower the decay width, as compared with previous predictions without the $O(α_{s}v^{2})$ correction, and thus result in a good agreement with the recent BESIII measurement.

description: Using recent dimensionality reduction techniques in large systems of coupled phase oscillators exhibiting bistability, we analyze complex macroscopic behavior arising when the coupling between oscillators is allowed to evolve slowly as a function of either macroscopic or local system properties. For example, we observe macroscopic excitability and intermittent synchrony in a system of time-delayed Kuramoto oscillators with Hebbian and anti-Hebbian learning. We demonstrate the robustness of our findings by considering systems with increasing complexity, including time-delayed oscillators with adaptive network structure and community interaction, as well as a system with bimodally distributed frequencies.

This allows us to prove in an elementary way that these algebras satisfy the homological properties of an `affine quasi-hereditary algebra.' In simply-laced types these properties were established originally by Kato via a geometric approach. We also construct some Koszul-like projective resolutions of standard modules corresponding to multiplicity-free positive roots.

description: We study the time evolution of correlation functions in long-range interacting quantum Ising models. For a large class of initial conditions, exact analytic results are obtained in arbitrary lattice dimension, both for ferromagnetic and antiferromagnetic coupling, and hence also in the presence of geometric frustration. In contrast to the nearest-neighbour case, we find that correlations decay like stretched or compressed exponentials in time. Provided the long-range character of the interactions is sufficiently strong, pronounced prethermalization plateaus are observed and relaxation timescales are widely separated. Specializing to a triangular lattice in two spatial dimensions, we propose to utilize these results for benchmarking of a recently developed ion-trap based quantum simulator.

description: The Search and Rescue management activities aim to reach the objectives according to the project plan and within the allocated budget, resources, and with the needed quality. Therefore, this deliverable defines the structures, the procedures, and the supporting documents needed to assure the quality of the project deliverables and project management activities
 With regards to the project management structure, it is based on the following bodies and roles: (i) the Project Coordinator (PC) as the main responsible of coordination and interface to the Commission (ii) the General Assembly (GA) as the supervisory body for the project execution with monitoring functions and decision-making body in all relevant project matters (iii) the Scientific-Technical Coordinator (STC) as the main responsible for the overall project scientific and technical implementation, (iv) the Scientific Technical Committee (STC) as the body supervising accordingly the scientific and technical activities and results of the project, (v) the Dissemination, Exploitation and Innovation Committee (DEIC) as the body responsible for the dissemination, exploitation and innovation activities of the S& project and (vi) the Management Support Team (MST), as the instrument supporting and facilitating the work of the PC. Additionally, the project will involve Advisory and Ethics Boards, respectively engaging decision makers and stakeholder community representatives providing insights and recommendations, and independent experts monitoring and providing guidance over ethics-related issues.
 In order to ensure a fluent communication inside the consortium, the PC will cost-effectively schedule meetings, which will allow the participants to communicate face to face, only when necessary and will provide an alternative and maintain the communication during the whole project lifetime through different communication tools (e.g., teleconferences, mailing lists, project repository, etc.).
 The document at hand further includes a quality assurance plan that will ensure that project quality remains at a high level throughout the project cycle. This plan sets a final internal review for each deliverable. The Quality Assurance is managed by the Quality Manager (QM) of the Search and Rescue project, who reports to the Project Coordinator.
 Finally, the document details a risk management plan in order to anticipate risky situations that can affect the project's normal progress or even put it in danger. Additionally, a list of potential mitigation measures is presented in order to take decisions accordingly and act in time to minimise the impact.
S-stars in the Galactic center and hypervelocity stars in the Galactic halo: two faces of the tidal breakup of stellar binaries by the central massive black hole?

description: In this paper, we investigate the link between the hypervelocity stars (HVSs) discovered in the Galactic halo and the S-stars moving in the Galactic center (GC), under the hypothesis that they are both the products of the tidal breakup of the same population of stellar binaries by the central massive black hole (MBH). By adopting several hypothetical models for binaries to be injected into the vicinity of the MBH and doing numerical simulations, we realize the tidal breakup processes of the binaries and their follow-up evolution. We find that many statistical properties of the detected HVSs and S-stars can be reproduced under some binary injecting models, and their number ratio can be reproduced if the stellar initial mass function is top-heavy (e.g., with slope ~-1.6). The total number of the captured companions is ~50 that have masses in the range ~3-7Msun and semimajor axes

description: We use the technique of "classical realizability" to build new models of ZF + DC in which R is not well ordered. This gives new relative consistency results, probably not obtainable by forcing. This gives also a new method to get programs from proofs of arithmetical formulas with dependent choice.

The muon anomalous magnetic moment in the Randall-Sundrum model

description: We calculate the anomalous magnetic moment of the muon in the minimal Randall-Sundrum model with standard model fields in five-dimensional (5D) warped space and a brane-localized Higgs. We use a fully 5D framework to compute the one-loop matching coefficients of the effective theory at the electroweak scale. The extra contribution to the anomalous magnetic moment from the model-independent gauge-boson exchange contributions Δa_μis approximately 8.8*10^-11 (1TeV/T)^2, where 1/T denotes the location of the TeV brane in conformal coordinates, and is related to the mass of the lowest gauge boson KK excitation, which is roughly 2.5T. The result constitutes the first complete determination of the gauge-boson contribution to g-2 and is robust against the variation of the bulk fermion masses and 5D Yukawa coupling. We also determine the strongly model-parameter dependent effect of Higgs-exchange diagrams.

description: Presentazione su call tenuta alla GenOA Week 2023 nella sessione "Biblioteche per l'Open Science"
Abstract degli autori:
Il Sistema Bibliotecario di Ateneo (SBA) di Ca'Foscari è organizzato in 4 biblioteche di area disciplinare (umanistica, linguistica, economico-giuridica e scientifica). una Biblioteca Digitale (BDA). Lo SBA serve oltre 1300 ricercatori, assegnisti, cultori della materia e dottorandi attivi nelle discipline giuridico-economiche, delle scienze umanistiche, degli studi linguistici, di scienze ambientali, informatica e statistica che producono circa 2500 pubblicazioni scientifiche ogni anno. L'Ateneo promuove, secondo il modello Green Open Access, il deposito e la diffusione della produzione scientifica dei propri ricercatori tramite l'archivio istituzionale ARCA (Archivio Ricerca Ca'Foscari), attivato nel 2014. 
L'Ateneo ha risposto all'impulso del Piano Nazionale della Scienza Aperta 2021-2027 attraverso il Piano Strategico di Ateneo 2021-2026 (PSA) che individua nelle sue principali azioni la diffusione delle pratiche della Scienza Aperta (SA) per favorire l'aumento della circolazione dei risultati scientifici, migliorare i servizi e le infrastrutture di ricerca e rafforzare le politiche di internazionalizzazione dell'Ateneo. 
In questo contesto è nata la necessità di elaborare una specifica Policy della Scienza Aperta che superasse e ricomprendesse le precedenti Policy focalizzate in particolare solo sugli aspetti dell'Open Access. Come raccomandato dai principali documenti delle Agenzie europee ed internazionali, i benefici della Scienza Aperta sono possibili solamente quando diventano parte integrante del processo di ricerca in tutti i suoi livelli. 
In questo senso la Policy descrive una visione comune e fornisce una guida su come integrare le pratiche della Scienza Aperta nel processo di ricerca scientifica a Ca'Foscari. 
L'intervento vuole descrivere la roadmap delle azioni pianificate che partendo dall'adozione della Policy, si sviluppa nell'acquisizione di una infrastruttura per i dati  della Scienza Aperta, fino alla formazione del personale.
The Boltzmann equation in special and general relativity

description: Relativistic field equations for a gas in special and general relativity are determined from the Boltzmann equation. The constitutive equations are obtained from the Chapman-Enskog methodology applied to a relativistic model equation proposed by Anderson and Witting. Two applications in general relativity are considered: one refers to a gas in a homogeneous and isotropic Universe where irreversible processes are present during its evolution; in the other it is analyzed a gas under the influence of a spherically symmetrical non-rotating and uncharged source of the gravitational field.

Moduli Stabilization and the Holographic RG for AdS and dS

description: We relate moduli stabilization ($V'=0$) in the bulk of $AdS_D$ or $dS_D$ to basic properties of the Wilsonian effective action in the holographic dual theory on $dS_{D-1}$: the single-trace terms in the action have vanishing beta functions, and higher-trace couplings are determined purely from lower-trace ones. In the de Sitter case, this encodes the maximal symmetry of the bulk spacetime in a quantity which is accessible within an observer patch. Along the way, we clarify the role of counterterms, constraints, and operator redundancy in the Wilsonian holographic RG prescription, reproducing the expected behavior of the trace of the stress-energy tensor in the dual for both $AdS_D$ and $dS_D$. We further show that metastability of the gravity-side potential energy corresponds to a nonperturbatively small imaginary contribution to the Wilsonian action of pure de Sitter, a result consistent with the need for additional degrees of freedom in the holographic description of its ultimate decay.
