title: Corpo vivente e cyberspace: la dimensione hyletica nella costituzione della conoscenza
Creators: name: Ales Bello , Angela
Publisher: name: Roma Tre-Press
Year: 2020

description: Quando si ascoltano termini come corpo “vivente” o “vissuto”, e hyletico, si pensa subito a Edmund Husserl, specialmente quando identifica la dimensione hyletica con il primo gradino di costituzione dell’essere umano. Questo livello è strettamente legato alla corporeità. Qui sta la novità del metodo fenomenologico. Nel mio scritto esamino la relazione tra il corpo vivente e lo spazio virtuale, espressa attraverso la fantasia. Particolarmente interessante è l’uso dello spazio virtuale in geometria dove il cyberspazio può essere una strumento per spiegare il suo significato principale. In ogni caso si può anche osservare che lo spazio virtuale non deve essere privilegiato con il rischio di dimenticare lo spazio reale e l’importanza della propria corporeità.

description: Stakeholder management encompasses different activities which have a significant impact on the project realization. Business practice indicates that before and during the project realization, an organization that implements the project, or even consortium of entities, should put much attention in to satisfy different stakeholders' requirements. The aim of this paper is ranking of reverse supply chain (RSC) entities upon key stakeholders requirements' fulfillment. In the first step of research, key stakeholders are identified through stakeholder management analysis. Their requirements are analyzed and weighted by using fuzzy Delphi method. The decision makers perform their assessment taking in account linguistic expressions, so they do not need to think about precise numbers. In this way, the process of decision making is made easier compared to the conventional approach. The determination of the RSC entities upon key stakeholders requirements’ fulfillment is performed by using the fuzzy ELECTRE method.

description: In this paper, we have introduced and investigated the collective behavior of a network of memristive Hindmarsh-Rose (HR) neurons. The proposed model was built considering the memristive autapse of the traditional 2D HR neuron. Using the one-parameter bifurcation diagram and its corresponding maximal Lyapunov exponent graph, we showed that the proposed model was able to exhibit a reverse period doubling route to chaos, phenomenon of interior and exterior crises. Three different configurations of the ring-star network of the memristive HR neuron model, including ring-star, ring, and star, have been considered. The study of those network configurations revealed incoherent, coherent, chimera, and cluster state behaviors. Coherent behavior is characterized by synchronization of the neurons of the network, while incoherent behaviors are characterized by the absence of synchronization. Chimera states refer to a different state where there is a coexistence of synchronized and asynchronized nodes of the network. One of the interesting results of the paper is the prevalence of double-well chimera states in both ring and ring-star network which has been first mentioned in the case of the memristive HR neuron model.

description: Human brain maturation is characterized by the prolonged development of structural and functional properties of large-scale networks that extends into adulthood. However, it is not clearly understood which features change and which remain stable over time. Here, we examined structural connectivity based on diffusion tensor imaging (DTI) in 121 participants between 4 and 40 years of age. DTI data were analyzed for small-world parameters, modularity, and the number of fiber tracts at the level of streamlines. First, our findings showed that the number of fiber tracts, small-world topology, and modular organization remained largely stable despite a substantial overall decrease in the number of streamlines with age. Second, this decrease mainly affected fiber tracts that had a large number of streamlines, were short, within modules and within hemispheres; such connections were affected significantly more often than would be expected given their number of occurrences in the network. Third, streamline loss occurred earlier in females than in males. In summary, our findings suggest that core properties of structural brain connectivity, such as the small-world and modular organization, remain stable during brain maturation by focusing streamline loss to specific types of fiber tracts.

description: La questione dell’estraneo non è certo un problema molto frequentato dalla tradizione filosofica, anche se si è ripetutamente affacciato nei contesti più diversi. Con Husserl e la tradizione fenomenologica, l’esperienza è stata indagata anche secondo i suoi fallimenti, laddove, per esempio, qualcosa si mostra nascondendosi. Questa estraneità tematizzata è una specie di assenza in carne e ossa, una distanza nella prossimità, l’accessibilità di ciò che resta inaccessibile, come Husserl ha sottolineato nelle sue Meditazioni cartesiane. Ma come affrontare tutto questo senza privarlo del suo pungolo? Si tratta non di discutere intorno a una questione, ma di partire da un intoppo, cercando risposte, nella consapevolezza che il nostro pathos inizia comunque da altrove. Così l’essere umano si rivela un homo respondens.

description: The Fredholm index of unbounded operators defined on generalized solutions of nonlocal elliptic problems in plane bounded domains is investigated. It is known that nonlocal terms with smooth coefficients having zero of a certain order at the conjugation points do not affect the index of the unbounded operator. In this paper, we construct examples showing that the index may change under nonlocal perturbations with coefficients not vanishing at the points of conjugation of boundary-value conditions.

description: This paper investigates an application of ISO 10004 in a specific care continuum assumed to be an integrated health care case. It also illustrates the integrative augmentation of ISO 10001- and ISO 10002-based promise and feedback systems. An emergency and inpatient care continuum within a Canadian hospital was investigated by interviewing nurses and managers. Patients' service encounters with the care and support providers were examined and the existing measurement activities were studied. Steps for customer satisfaction measurement along the continuum were defined. Sources to determine patient expectations were identified and the measurement activities, such as a survey encompassing all stages within the care continuum, were developed. Research participants were interviewed again to verify the usefulness of the developed measurement activities. The presented work depicts the relationships among the aspects of customer satisfaction, key principles of integrated care and ISO 10004. It is one of the first examples of an application of ISO 10004 and the integrative augmentation of systems standardized by the ISO 10000 customer satisfaction series in health care. This paper is a revised version of Khan et al. (2017).

description: Today's quantum computers operate with a binary encoding that is the quantum analog of classical bits. Yet, the underlying quantum hardware consists of information carriers that are not necessarily binary, but typically exhibit a rich multilevel structure, which is artificially restricted to two dimensions. A wide range of applications from quantum chemistry to quantum simulation, on the other hand, would benefit from access to higher-dimensional Hilbert spaces, which conventional quantum computers can only emulate. Here we demonstrate a universal qudit quantum processor using trapped ions with a local Hilbert space dimension of up to 7. With a performance similar to qubit quantum processors, this approach enables native simulation of high-dimensional quantum systems, as well as more efficient implementation of qubit-based algorithms.

description: Fundamental big-picture challenges face the enterprise of burgeoning space test, which may also have an impact on the syllabus and training of a possible future Space Test Pilot School. Test fundamentals and test conduct under stresses of time and fuel will be where the rubber meets the road. This paper specifically discusses four of those challenges, and their impact on US Space Force operators. (1) Testing limits of space capabilities. Space vehicles have traditionally imposed very strict operating limits. A culture shift from the top-down will be required before space testers are allowed to test spacecraft limits as freely as air-breathing test pilots do today. (2) Permitted procedures. There are a limited number of contingency procedures at a space operator's disposal, further constrained within themselves. (3) Safety nets. A discussion of space-specific methods that mitigate risks in operations, and the need for more agile fault-detection. (4) Operator proficiency. The qualifications and recency of a tester at the controls must be considered in the context of a single misstep potentially resulting in the entire asset being lost. We suggest that hours in high-risk test per spacecraft may become the defining factor for high-risk space test execution.

description: The in-plane thermal conductivity of iron-based superconductor Ca$_{10}$(Pt$_{4-δ}$As$_8$)((Fe$_{1-x}$Pt$_{x}$)$_2$As$_2$)$_5$ single crystal (``10-4-8", $T_c$ = 22 K) was measured down to 80 mK. In zero field, the residual linear term $κ_0/T$ is negligible, suggesting nodeless superconducting gaps in this multiband compound. In magnetic fields, $κ_0/T$ increases rapidly, which mimics those of multiband superconductor NbSe$_2$ and LuNi$_2$B$_2$C with highly anisotropic gap. Such a field dependence of $κ_0/T$ is an evidence for multiple superconducting gaps with quite different magnitudes or highly anisotropic gap. Comparing with the London penetration depth results of Ca$_{10}$(Pt$_3$As$_8$)((Fe$_{1-x}$Pt$_{x}$)$_2$As$_2$)$_5$ (``10-3-8") compound, the 10-4-8 and 10-3-8 compounds may have similar superconducting gap structure.

description: Cell deconvolution methods have emerged in recent years as relevant bioinformatics approaches for predicting the proportions of cell types present in biological samples profiled by bulk RNA-seq. Within the framework of the European KATY project (https://katy-project.eu/), we are interested in the heterogeneity of the tumor microenvironment of the clear cell renal cell carcinoma (ccRCC) and its influence on the ability to predict a patient's response to a treatment.
 To meet this objective, we have optimized a bioinformatics protocol for the analysis of single-cell RNA-seq data and the prediction of cell fractions by deconvolution methods. We evaluated the cell deconvolution methods
 CIBERSORTx and MuSiC. The single cell RNA-seq matrix used in our work to perform cell deconvolution was optimized from the one obtained from 11 adult patients with ccRCC.
 We generated pseudo-Bulk RNA-seq matrices from the single cell RNA- seq matrix to assess the performance of cell deconvolution methods. Then, we performed deconvolution on a cohort of bulk RNA-seq data consisting of 311 ccRCC tumor samples and assessed the quality of our predictions by comparison with tumor purity scores

description: Il bicentenario della nascita di Concepción Arenal (1820-1893) offre l’opportunità di riflettere sulla sua opera di saggista, penalista e attivista dei diritti civili e sociali. Con i suoi scritti e il suo impegno ha anticipato molte delle istanze che avrebbero animato il dibattito politico dei primi decenni del XX secolo: la difesa della donna, la riforma penale, la protezione dell’infanzia e la questione operaia. Nell’articolo si mette in luce la preoccupazione che ebbe la Arenal per le categorie più vulnerabili, in particolare per la donna, convinta che la giustizia è inseparabile dalla carità e che l’educazione è la leva più efficace per un autentico sviluppo.

description: Building upon a new dynamical model for the X-ray binary LMC X-3, we measure the spin of its black hole primary via the continuum-fitting method. We consider over one thousand thermal-state RXTE X-ray spectra of LMC X-3. Using a large subset of these spectra, we constrain the spin parameter of the black hole to be spin = 0.21(+0.18,-0.22), 90% confidence. Our estimate of the uncertainty in spin takes into account a wide range of systematic errors. We discuss evidence for a correlation between a black hole's spin and the complexity of its X-ray spectrum.

description: The Lambda-doublet transitions in CH at 3.3 and 0.7 GHz are unusually sensitive to variations in the fine-structure constant and the electron-to-proton mass ratio. We describe methods used to measure the frequencies of these transitions with Hz-level accuracy. We produce a pulsed supersonic beam of cold CH by photodissociation of CHBr3, and we measure the microwave transition frequencies as the molecules propagate through a parallel-plate transmission line resonator. We use the molecules to map out the amplitude and phase of the standing wave field inside the transmission line. We investigate velocity-dependent frequency shifts, showing that they can be strongly suppressed through careful timing of the microwave pulses. We measure the Zeeman and Stark effects of the microwave transitions, and reduce systematic shifts due to magnetic and electric fields to below 1 Hz. We also investigate other sources of systematic uncertainty in the experiment.

The paper reviews experimental data which have led to the evidence for this resonance. Alternative explanations of the phenomenon at W ~ 1.685 GeV, namely the interference of well-known resonances and the sub-threshold meson-baryon production, are discussed as well.

description: In many industrial process and operations heat exchangers are one of the most important thermal

devices. Shell and tube heat exchangers are the common types of heat exchangers and sustained

a wide range of operating temperature and pressure. Controlling heat exchanger system is a very

challenging task due to its nonlinearity. While the amount of flow rates of both manipulated

variable and disturbance variable changes, the gain, time delay and time constant varies, hence

causing system nonlinearity. The solution for such problems is finding mathematical model that

represents the real system and designing suitable controller which remove the offset, making fast

settling with minimum steady state error possible. Input data for MATLAB system identification

tool was generated experimentally.

description: This short review presents a selected history of the mutual fertilization between physics and economics, from Isaac Newton and Adam Smith to the present. The fundamentally different perspectives embraced in theories developed in financial economics compared with physics are dissected with the examples of the volatility smile and of the excess volatility puzzle. The role of the Ising model of phase transitions to model social and financial systems is reviewed, with the concepts of random utilities and the logit model as the analog of the Boltzmann factor in statistic physics. Recent extensions in term of quantum decision theory are also covered. A wealth of models are discussed briefly that build on the Ising model and generalize it to account for the many stylized facts of financial markets. A summary of the relevance of the Ising model and its extensions is provided to account for financial bubbles and crashes. The review would be incomplete if it would not cover the dynamical field of agent based models (ABMs), also known as computational economic models, of which the Ising-type models are just special ABM implementations. We formulate the ``Emerging Market Intelligence hypothesis'' to reconcile the pervasive presence of ``noise traders'' with the near efficiency of financial markets. Finally, we note that evolutionary biology, more than physics, is now playing a growing role to inspire models of financial markets.

description: In this paper we consider quintessence reconstruction of interacting holographic dark energy in a non-flat background. As system's IR cutoff we choose the radius of the event horizon measured on the sphere of the horizon, defined as $L=ar(t)$. To this end we construct a quintessence model by a real, single scalar field. Evolution of the potential, $V(ϕ)$, as well as the dynamics of the scalar field, $ϕ$, are obtained according to the respective holographic dark energy. The reconstructed potentials show a cosmological constant behavior for the present time. We constrain the model parameters in a flat universe by using the observational data, and applying the Monte Carlo Markov chain simulation. We obtain the best fit values of the holographic dark energy model and the interacting parameters as $c=1.0576^{+0.3010+0.3052}_{-0.6632-0.6632}$ and $ζ=0.2433^{+0.6373+0.6373}_{-0.2251-0.2251}$, respectively. From the data fitting results we also find that the model can cross the phantom line in the present universe where the best fit value of of the dark energy equation of state is $w_D=-1.2429$.

description: The competition between strength and correlation of coupling terms in a Hamiltonian defines numerous phenomenological models exhibiting spectral properties interpolating between those of Poisson (integrable) and Wigner-Dyson (chaotic) ensembles. It is important to understand how the off-diagonal terms of a Hamiltonian evolve as one or more symmetries of an integrable system are explicitly broken. We introduce a deformed Poisson ensemble to demonstrate an exact mapping of the coupling terms to the underlying symmetries of a Hamiltonian. From the maximum entropy principle we predict a chaotic limit which is numerically verified from the spectral properties and the survival probability calculations.

Planetary Population Synthesis and the Emergence of Four Classes of Planetary System Architectures

description: Planetary population synthesis is a tool to understand the physics of planetary system formation. It builds on a model that includes a multitude of physical processes. The outcome can be statistically compared with exoplanet observations. Here, we review the population synthesis method and then use one population to explore how different planetary system architectures emerge and which conditions lead to their formation. The systems can be classified into four main architectures: Class I of near-in situ compositionally ordered terrestrial and ice planets, Class II of migrated sub-Neptunes, Class III of mixed low-mass and giant planets, broadly similar to the Solar System, and Class IV of dynamically active giants without inner low-mass planets. These four classes exhibit distinct typical formation pathways and are characterised by certain mass scales. Class I systems form from the local accretion of planetesimals followed by a giant impact phase, and the final planet masses correspond to the `Goldreich mass'. Class II systems form when planets reach the `equality mass' (equal accretion and migration timescales) before the dispersal of the gas disc, but not large enough to allow for rapid gas accretion. Giant planets form when the `equality mass' allows for rapid gas accretion while the planet are migrating, i.e. when the critical core mass is reached. The main discriminant of the four classes is the initial mass of solids in the disc, with contributions from the lifetime and mass of the gas disc. The breakdown into classes allows to better understand which physical processes are dominant. Comparison with observations reveals certain differences to the actual population, pointing at limitation of theoretical understanding. For example, the overrepresentation of synthetic super Earths and sub-Neptunes in Class I causes these planets to be found at lower metallicities than in observations.

description: We give an analysis over a variation of causal sets where the light cone of an event is represented by finitely branching trees with respect to any given arbitrary dynamics. We argue through basic topological properties of Cantor space that under certain assumptions about the universe, spacetime structure and causation, given any event $x$, the number of all possible future worldlines of $x$ within the many-worlds interpretation is uncountable. However, if all worldlines extending the event $x$ are `eventually deterministic', then the cardinality of the set of future worldlines with respect to $x$ is exactly $\aleph_0$, i.e., countably infinite. We also observe that if there are countably many future worldlines with respect to $x$, then at least one of them must be necessarily `decidable' in the sense that there is an algorithm which determines whether or not any given event belongs to that worldline. We then show that if there are only finitely many worldlines in the future of an event $x$, then they are all decidable. We finally point out the fact that there can be only countably many terminating worldlines.

description: Changes are inevitable in a construction project and can impact project’s time, cost, other aspects such as labor productivity, safety, and working relationships. A key challenge of change management is to identify changes and predict their impacts before implementation so that impacts can be minimized. However, different set of entity types in a construction project such as teams, components, deliverables, activities and parameters, as well as complex interdependencies that exist among these entity types, makes difficult to manage changes. To predict changes and their impacts holistically, entity types should be modeled in an integrated manner explicitly. Therefore, objective of the study is to develop a matrix-based framework to predict changes by modeling multiple entity types in a construction project. The proposed matrix-based framework integrates two matrix-based modeling concepts: Axiomatic Design (AD) and Multiple Domain Matrix (MDM). AD principles are utilized for early change identification. MDM principles are used for tracking change propagations across multiple entity types. A schedule risk model is proposed for estimating delays due to changes in entity types. The scope of study is to predict delays due to requirement changes. Framework is validated using data from an ongoing hospital construction project. The findings revealed framework can identify and predict all possible changes accurately.

description: The existence of Feller semigroups arising in the theory of multidimensional diffusion processes is studied. Unbounded perturbations of elliptic operators (in particular, integro-differential operators) are considered in plane bounded regions. Their domain of definition is given by a nonlocal boundary condition involving the integral over the closure of the region with respect to a nonnegative Borel measure. The support of the measure may intersect with the boundary, and the measure need not be small. We formulate sufficient conditions on unbounded perturbations of elliptic operator and on the Borel measure in the nonlocal boundary condition which guarantee that the corresponding nonlocal operator is a generator of a Feller semigroup.

description: The primordial confrontation underlying the existence of our universe can be conceived as the battle between entropy and complexity. The law of ever-increasing entropy (Boltzmann H-theorem) evokes an irreversible, one-directional evolution (or rather involution) going uniformly and monotonically from birth to death. Since the 19th century, this concept is one of the cornerstones and in the same time puzzles of statistical mechanics. On the other hand, there is the empirical experience where one witnesses the emergence, growth and diversification of new self-organized objects with ever-increasing complexity. When modeling them in terms of simple discrete elements one finds that the emergence of collective complex adaptive objects is a rather generic phenomenon governed by a new type of laws. These 'emergence' laws, not connected directly with the fundamental laws of the physical reality, nor acting 'in addition' to them but acting through them were called by Phil Anderson 'More is Different', 'das Maass' by Hegel etc. Even though the 'emergence laws' act through the intermediary of the fundamental laws that govern the individual elementary agents, it turns out that different systems apparently governed by very different fundamental laws: gravity, chemistry, biology, economics, social psychology, end up often with similar emergence laws and outcomes. In particular the emergence of adaptive collective objects endows the system with a granular structure which in turn causes specific macroscopic cycles of intermittent fluctuations.

description: We combine long-term photometric observations in multiple band passes to determine the rotational light curve for the binary Kuiper-Belt object (79360) Sila-Nunam. We measure an unambiguous fundamental period of 6.2562 +/- 0.002 d, within 0.02% of half the orbital period (Porb = 12.50995 +/- 0.00036 d) determined earlier from HST observations resolving the binary. The light curve is double-peaked, and well fit by the sum of two sinusoids: a primary with period Porb/2 and peak-to-peak amplitude 0.120 +/- 0.012 mag and a secondary with period Porb and peak-to-peak amplitude 0.044 +/- 0.010 mag. Excluding observations within ~0.1 deg of opposition, we measure a linear solar phase dependence with slope 0.147 +/- 0.018 mag deg-1 and a mean absolute magnitude in the Gunn g band of 6.100 +/- 0.006 mag. There is no rotational color variation exceeding 4%. We also observe that eclipses occur centered on light curve minima to within 0.3%, requiring the long axis of at least one of the two bodies to point precisely toward the other. Assuming the binary is doubly synchronous and both rotation axes are aligned with the orbital angular momentum vector, our observations jointly constrain triaxial shape models for Sila and Nunam such that the product of their long-to-intermediate axes ratios is 1.120 +/- 0.01. Hence both bodies are elongated by 6%, or else one is elongated by 6% to 12%, and the other by less than 6%.

description: Hawking radiation is one of the quantum features of a black hole that can be understood as a quantum tunneling across the event horizon of the black hole, but it is quite difficult to directly observe the Hawking radiation of an astrophysical black hole. Here, we report a fermionic lattice-model-type realization of an analogue black hole by using a chain of 10 superconducting transmon qubits with interactions mediated by 9 transmon-type tunable couplers. The quantum walks of quasi-particle in the curved spacetime reflect the gravitational effect near the black hole, resulting in the behaviour of stimulated Hawking radiation, which is verified by the state tomography measurement of all 7 qubits outside the horizon. In addition, the dynamics of entanglement in the curved spacetime is directly measured. Our results would stimulate more interests to explore the related features of black holes using the programmable superconducting processor with tunable couplers.

description: Il lockdown causa Covid ha colpito tutte le categorie, ma uno dei danni è avvenuto proprio nella popolazione accademica, soprattutto quella femminile. Infatti quando finalmente sembrava che a furia di battaglie le donne si   fossero liberate del carico di lavoro domestico, ecco all’improvviso rispuntare fuori il ruolo tradizionale femminile, cioè occuparsi della casa, preparare il cibo per tutti, andare al supermarket. Le donne sono state  riportate in blocco a cinquant’anni fa: tutto il tempo usualmente dedicato alla ricerca, all’insegnamento, allo scambio di idee con colleghi e ricercatori di ogni ordine e grado, si è ridotto allo stretto indispensabile e a volte neanche quello. Di fatto la pandemia ci ha messi davanti a una precisa realtà: riorganizzazione, fare appello alle nostre intelligenze, artefici dei privilegi acquisiti, per venire a capo del peggior problema di work-balance mai capitato.

description: The existence of Feller semigroups arising in the theory of multidimensional diffusion processes is studied. An elliptic operator of second order is considered on a plane bounded region $G$. Its domain of definition consists of continuous functions satisfying a nonlocal condition on the boundary of the region. In general, the nonlocal term is an integral of a function over the closure of the region $G$ with respect to a nonnegative Borel measure $μ(y,dη)$, $y\in\partial G$. It is proved that the operator is a generator of a Feller semigroup in the case where the measure is atomic. The smallness of the measure is not assumed.

Abstract Empagliflozin (Jardiance®), a sodium-glucose cotransporter 2 inhibitor (SGLT2i) initially developed to treat type 2 diabetes mellitus (T2DM), has also been approved in the EU and USA for the treatment of all adults with symptomatic chronic heart failure (CHF), regardless of their left ventricular ejection fraction (LVEF). In pivotal phase III trials in ambulant patients with symptomatic CHF and mildly-reduced or preserved ejection fraction (EMPEROR-Preserved; LVEF > 40%) or those with symptomatic CHF and reduced ejection fraction (EMPEROR–Reduced; LVEF ≤ 40%), the addition of oral empagliflozin 10 mg/day to standard of care significantly reduced the risk of cardiovascular (CV) death or hospitalization for HF (HHF), as well as that of a number of other outcomes indicative of worsening HF, compared with placebo. The beneficial effect of empagliflozin on CV death/HHF was seen irrespective of the presence or absence of T2DM and regardless of background HF therapies. In addition, empagliflozin significantly improved health-related quality of life (HRQOL) and was generally well tolerated, with an adverse event profile that was generally consistent with that seen in patients with T2DM. Thus, empagliflozin is a valuable treatment option for ambulant patients with symptomatic CHF across a broad LVEF spectrum. © Springer Nature Switzerland AG 2022
title: Il soggetto della narrazione psichiatrica

description: Il presente testo ripropone la questione della relazione tra follia e cura. Nel solco di una tradizione inaugurata dalla psichiatria fenomenologica e dagli studi di Michel Foucault, ci proponiamo di discutere la concezione della follia sottesa ad alcune teorie psichiatriche elaborate a partire dal XX secolo. Lo strumento concettuale attraverso cui confronteremo i vari modelli di cura psichiatrici sarà la narrazione: non c’è infatti alcun modello psichiatrico che possa eludere il confronto con la narrazione esistenziale dell’individuo malato. In primo luogo, perché non c’è processo di indagine psichiatrica che si collochi al di fuori di un’ermeneutica del vissuto soggettivo del paziente. In secondo luogo, perché la parola (scritta o narrata), producendo soggettività, consente di avvicinare l’esperienza esistenziale dell’individuo malato a quello sano. In ultima analisi, considerare la follia come un oggetto costituitosi recentemente come malattia e codificato da una scienza che, in quanto discorso razionale, le è estranea per definizione, mette in luce come il discorso sulla follia sia il resoconto esterno e parziale di un vissuto raramente messo a confronto con l’auto-narrazione. Se quindi la follia continua a interrogare la nostra soggettività a proposito del suo rapporto con il mondo e con ciò che è altro da lei è forse perché non si è mai dato un discorso che accettasse la possibilità concreta della radicale incomunicabilità tra follia e ragione e che, in definitiva, si limitasse ad esibirla.

description: The benefits that can be derived from reusing software include accelerated development, reduced cost, reduced risk and effective use of specialists. Reuse of software artifacts during the initial stages of software development increases reuse benefits, because it allows subsequent reuse of later stage artifacts derived from earlier artifacts. UML is the de facto modeling language used by software developers during the initial stages of software development such as requirements engineering, architectural and detailed design. This survey analyzes previous works on UML artifacts reuse. The analysis considers four perspectives: retrieval method, artifact support, tool support and experiments performed. As an outcome of the analysis, some suggestions for future work on UML artifacts reuse are also provided

description: L'analisi si propone di precisare e approfondire gli aspetti più accreditati, nello stato dell'arte, a proposito di un confronto tra Pirandello e Goffman, a partire dalle indicazioni fornite dal sociologo stesso. Del pensiero di quest’ultimo vengono ripresi i concetti fondamentali, con particolare attenzione per La vita sociale come rappresentazione e per Frame Analysis. Dall’immensa produzione pirandelliana sono stati assunti passi e stralci di opere che più si prestano a tale confronto, ma anche all’evidenziazione di  diversità ideologiche e culturali. Il focus del discorso, infatti, si concentra sulla volontà di far emergere le specificità del pensiero del sociologo rispetto a quelle del ʻfilosofo-letteratoʼ, alla luce delle loro peculiari visioni del mondo, dell’uomo e della società.

description: We describe fabrication and testing of composite flux qubits combining Nb- and Al-based superconducting circuit technology. This hybrid approach to making qubits allows for employing pi-phase shifters fabricated using well-established Nb-based technology of superconductor-ferromagnet-superconductor Josephson junctions. The important feature here is to obtain high interface transparency between Nb and Al layers without degrading sub-micron shadow mask. We achieve this by in-situ Ar etching using e-beam gun. Shadow-evaporated Al/AlOx/Al Josephson junctions with Nb bias pads show the expected current-voltage characteristics with reproducible critical currents. Using this technique, we fabricated composite Nb/Al flux qubits with Nb/CuNi/Nb pi-shifters and measured their magnetic field response. The observed offset between the field responses of the qubits with and without pi-junction is attributed to the pi phase shift. The reported approach can be used for implementing a variety of hybrid Nb/Al superconducting quantum circuits.

description: Digital image comparison and matching brings many advantages over the traditional subjective human comparison, including speed and reproducibility. Despite the existence of an abundance of image difference metrics, most of them are not suited for high-resolution transmission electron microscopy (HRTEM) images. In this work we adopt two image difference metrics not widely used for TEM images. We compare them to subjective evaluation and to the mean squared error in regards to their behaviour regarding image noise pollution. Finally, the methods are applied to and tested by the task of determining precipitate sizes of a model material.
