Abbiamo veramente bisogno dell’identità? Alcune precauzioni per l’uso di un concetto ambiguo
Creators: name: Caniglia, Enrico
Publisher: name: Università degli Studi di Firenze
Year: 2013

description: The essay critically discusses some theoretical and empirical aporias that characterize the sociological concept of identity. In particular, it highlights the common sense origin of the category of identity and the characteristics of essentialism and realism that characterize its psychological root. Finally, it puts forward an alternative way of research according to which the identity no longer identifies a real group but a discursive practice.

description: The focus of the essay is an reinterpretation of Didactica Magna with particular attention to the dimension of childhood. The children are like “arbusculas Dei”: so the parents, but also those who preside over the political and ecclesiastical government of the whole community, must hasten to “plant, prune, irrigate”, because soon be seen in new generations clear progress towards of wisdom and piety. Important is the idea of Comenius to organize a nursery, thus bringing the education of children within a larger social project. The essay is an important contribution to the reinterpretation of pedagogical classics.

New evidence models: clinical trials in the age of AI and precision medicine

Publisher: name: F1000 Research Limited
Year: 2019

description: The "gold standard" by which physicians, scientists, and regulators have evaluated safety and efficacy in clinical research, the randomized controlled trial, has been consistent for over two hundred years. Today, digital transformation and AI are making new evidence models possible. These evidence models address both practical and ethical issues in human research. We will examine those issues, how precision medicine make them more acute, how digital and AI are allowing for new comparators and unprecedented data reuse, and how these new experimental and statistical models are -- at long last -- allowing that gold standard to evolve.

description: This article attempts to distinguish between two types of alienation, zero-sum and non-zero-sum, showing the different dynamics and implications. While the religious (Feuerbach) and socio-economic (Marx) alienations fall within the zero-sum ones, the cultural alienation, that occurs when there is a contact between a majority and minority culture, such as in immigration or colonial contexts (Fanon), can be considered a non-zero-sum alienation.

description: In Jiang et al., we detected a bright flash (hereafter GN-z11-flash) that appeared as compact continuum emission during our Keck MOSFIRE observations of the galaxy GN-z11 at z ~ 11. We performed a comprehensive analysis of the origin of the flash using all available information and our current understanding of known man-made objects or moving objects in the solar system. We found that GN-z11-flash was likely a rest-frame UV flash associated with a long gamma-ray burst (GRB) from GN-z11. Recently, Steinhardt et al., Michalowski et al., and Nir et al. reported that GN-z11-flash was more likely from a satellite. While one cannot completely rule out the possibility of unknown satellites (or debris), we find that either the chance probabilities of being a satellite estimated by these authors have been largely overestimated or their identified satellites have been ruled out in our original analysis. Our new calculations show that the probability of GN-z11-flash being a satellite is still lower than that of it being a signal originated from GN-z11.

La ricerca in pedagogia

description: According to the author the pedagogical research has two convoys: the first epistemological (theoretical and historical), the other praxeology (experimental and empirical). Traveling together these two trains offer us the opportunity to see the face of critical pedagogy, or the reflexive dimension of doing research in education that translates better to the concept of action ricerca-azione. The most interesting aspect that emerges from this investigation is that the investigation is never separated from the ‘action and results that follow are never objective and definitive.

description: Light propagation in a medium made of densely packed dielectric spheres is investigated by using a rigorous diffraction theory. It is shown that a substantial suppression of the local density of states occurs in spectral domains where the single constituents exhibit Mie resonances. The local density of states decreases exponentially at the pertinent frequencies with a linearly increasing spatial extension of the aggregated spheres. It is shown that a self-sustaining random arrangement of core-shell spheres shows the same fundamental characteristics. Such approach offers a path towards easy to fabricate photonic materials with omnidirectional gaps that may find use in various applications.

A Pyramid Scheme for Particle Physics
Creators: name: Banks, Tom

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We introduce a new model, the Pyramid Scheme, of direct mediation of SUSY breaking, which is compatible with the idea of Cosmological SUSY Breaking (CSB). It uses the trinification scheme of grand unification and avoids problems with Landau poles in standard model gauge couplings. It also avoids problems, which have recently come to light, associated with rapid stellar cooling due to emission of the pseudo Nambu-Goldstone Boson (PNGB) of spontaneously broken hidden sector baryon number. With a certain pattern of R-symmetry breaking masses, a pattern more or less required by CSB, the Pyramid Scheme leads to a dark matter candidate that decays predominantly into leptons, with cross sections compatible with a variety of recent observations. The dark matter particle is not a thermal WIMP but a particle with new strong interactions, produced in the late decay of some other scalar, perhaps the superpartner of the QCD axion, with a reheat temperature in the TeV range. This is compatible with a variety of scenarios for baryogenesis, including some novel ones which exploit specific features of the Pyramid Scheme.

Biochemical and ultrastructural changes occurring in chicken pectoralis muscle inoculated with pseudomonas fragi
Creators: name: Sage, Gilbert
Publisher: name: University of British Columbia
Year: 2010

description: Chicken pectoralis muscle was inoculated with Pseudomonas fragi and incubated at room temperature. Alterations in the nonprotein nitrogen, water-soluble protein nitrogen, and salt-soluble protein nitrogen fractions were studied and attempts were made to relate these changes to structural changes observed by scanning and transmission electron microscopy. A significant decrease in myofibrillar protein solubility was found in the inoculated muscle during the protein extract-ability study. Results of the gel filtration study indicated that proteolysis of the sarcoplasmic proteins occurred and that the nonprotein nitrogen fraction increased due to growth of P. fragi. Alterations were observed in the disc gel electrophoretic patterns of the sarcoplasmic and myofibrillar protein fractions. Arginine, threonine, serine, proline and tyrosine were selectively utilized by P. fragi. Scanning electron micrographs indicated that proteolysis of the endomysium occurred after 2 days of incubation at 25°C. Proteolysis of the endomysium became more extensive as incubation time increased. After 4 days of incubation the myofibrils showed evidence of disruption as a result of bacterial growth. Disruption of the muscle fiber was limited to a depth of 2 to 4 micrometers after 9 days of incubation. Bacteria were observed growing between the muscle fibers. Proteolysis was not as extensive in samples incubated at 5°C. Electron micrographs prepared from thin sections of myofibrils inoculated with P. fragi showed marked disruption of the myofibrils due to bacterial growth. A clear zone, devoid of structural detail, surrounded the bacterial cell. A region of disrupted tissue exists between the clear zone and intact myofibrils. Cellular protrusions were observed on the surface of the bacteria.
Induced ferroelectric phases in TbMn_2O_5

description: The magnetostructural transitions and magnetoelectric effects reported in TbMn2O5 are described theoretically and shown to correspond to two essentially different mechanisms for the induced ferroelectricity. The incommensurate and commensurate phases observed between 38 and 24 K exhibit a hybrid pseudoproper ferroelectric nature resulting from an effective bilinear coupling of the polarization with the antiferromagnetic order parameter. This explains the high sensitivity of the dielectric properties of the material under applied magnetic field. Below 24 K the incommensurate phase shows a standard improper ferroelectric character induced by the coupling of two distinct magnetic order parameters. The complex dielectric behavior observed in the material reflects the crossover from one to the other transition regime. The temperature dependences of the pertinent physical quantities are worked out, and previous theoretical models are discussed.

description: That chiral symmetry is a crucial feature of the strong force was realized before the discovery of Quantum Chromodynamics. However, the full power it exerts on the structure of the nucleon became apparent only afterwards. We present a high-level and somewhat personal overview of its role in almost every aspect of proton structure, from its mass and spin to the asymmetry of its antimatter content and its strange quark content. The lessons learned from studying the proton are also vital with respect to the modern challenge of the nature of baryon excited states.

description: Η πρόγνωση της κατανάλωσης ηλεκτρικής ενέργειας είναι ένα θέμα που απασχολεί όλο και περισσότερους ερευνητές τα τελευταία χρόνια. Ειδικότερα σε επίπεδο οικιακής χρήσης, υπάρχουν πολλοί παράγοντες που συνεισφέρουν στην κατανάλωση ηλεκτρικής ενέργειας, κάτι που καθιστά το έργο της πρόγνωσής της ένα εξαιρετικά δύσκολο εγχείρημα. Η παρούσα εργασία έχει ως στόχο τη μοντελοποίηση δεδομένων κατανάλωσης ηλεκτρικής ενέργειας με τη χρήση μεθόδων υπολογιστικής νοημοσύνης, σε καταγραφές κατανάλωσης ηλεκτρικής ενέργειας ενός νοικοκυριού στο Παρίσι. Οι μετρήσεις πραγματοποιήθηκαν από «έξυπνους μετρητές» (smart meters), καταγράφοντας την κατανάλωση σε τρία ξεχωριστά δωμάτια του νοικοκυριού, όπου το καθένα περιλάμβανε έναν αριθμό από ηλεκτρικές συσκευές (πλυντήριο πιάτων, φούρνος, φούρνος μικροκυμάτων στο πρώτο δωμάτιο, πλυντήριο ρούχων, στεγνωτήριο, ψυγείο και φως στο δεύτερο, ηλεκτρικός θερμοσίφωνας και κλιματιστικό στο τρίτο). Οι μετρήσεις είχαν χρονική ανάλυση λεπτού και αντιστοιχούσαν σε διάστημα 4 χρόνων (12/2006-11/2010). Η πρόγνωση της κατανάλωσης ενέργειας έγινε με χρονικό βήμα 20 λεπτών. Το καλύτερο μοντέλο πρόγνωσης σε επίπεδο nowcasting έδωσε συντελεστή συσχέτισης ίσο με 0.91 και RMSE ίσο με 2.01 βατώρες ενεργής ενέργειας, ενώ σε επίπεδο forecasting το καλύτερο μοντέλο έδωσε συντελεστή συσχέτισης ίσο με 0.82 και RMSE ίσο με 4.57 βατώρες ενεργής ενέργειας.
description: The prediction of electric energy consumption is a topic that has concerned more and more researchers in recent years. Particularly at domestic usage level, there are many factors that contribute to electric energy consumption, which makes the task of predicting it quite a difficult undertaking. The objective of this thesis is to achieve the modeling of electric energy consumption data using Computational Intelligence methods. The modeling methods were applied to recordings of electricity consumption of a household in Paris. The measurements came from "smart meters". Measurements of electric energy consumption in three separate rooms of the household were included, each of which corresponded to some specific electrical devices (dishwasher, oven, microwave in the first room, washing-machine, tumble-drier, refrigerator and a light in the second one, electric water-heater and air-conditioner in the third one). The measurements had a temporal analysis of one minute and corresponded to a period of 4 years (12/2006-11/2010). The prediction of electric energy consumption was done with a temporal step of 20 minutes. The best prediction model in nowcasting level gave a correlation coefficient equal to 0.91 and a RMSE equal to 2.01 watt-hours of active energy, while in forecasting level the best prediction model gave a correlation coefficient equal to 0.82 and a RMSE equal to 4.57 watt-hours of active energy.

description: A non-Boolean extension of the classical probability model is proposed. The non-Boolean probabilities reproduce typical quantum phenomena. The proposed model is more general and more abstract, but easier to interpret, than the quantum mechanical Hilbert space formalism and exhibits a particular phenomenon (state-independent conditional probabilities) which may provide new opportunities for an understanding of the quantum measurement process. Examples of the proposed model are provided, using Jordan operator algebras.

Correlator of Wilson and t'Hooft Loops at Strong Coupling in $\mathcal{N}=4$ SYM Theory

description: We calculate the correlator of a 't Hooft and a Wilson coplanar circular concentric loops at strong coupling in N=4 SYM theory when it reduces to the calculation of the composite minimal surface in the curved space with the proper boundary conditions. The minimal admissible ratio of the radii of 't Hooft and Wilson loops for such a configuration is found to be $\mathrm{e}^{-1/2}\approx 0.606$ at zero temperature and the dependence of the minimal admissible radii ratio on temperature is derived. At low temperatures the minimal admissible ratio for 't Hooft and Wilson loops remains close to 0.6, whereas at high temperatures $T$ it becomes equal to $\frac{1}{πT}$. We find that at any temperature there exists a phase transition point: beneath some specific value of 't Hooft loop radius the dual counterpart of Wilson-'t Hooft correlator is organized as two disconnected surfaces in AdS, whereas for 't Hooft loop radius above it, there exists a connected configuration with a junction of monopole, charge and dyon surfaces. We suggest a generalization of the entanglement entropy for charged boundaries and make some comments on its calculation at strong coupling.

description: We report on rate-dependent fracture energy measurements over three decades of steady crack velocities in alginate and gelatin hydrogels. We evidence that, irrespective of gel thermo-reversibility, thermally activated "unzipping" of the non-covalent cross-link zones results in slow crack propagation, prevaling against the toughening effect of viscous solvent drag during chain pull-out, which becomes efficient above a few mm.s$^{-1}$. We extend a previous model [Baumberger {\it et al.} Nature Materials, {\bf 5}, 552 (2006)] to account for both mechanisms, and estimate the microscopic unzipping rates.

description: We consider large scale distributed optimization over a set of edge devices connected to a central server, where the limited communication bandwidth between the server and edge devices imposes a significant bottleneck for the optimization procedure. Inspired by recent advances in federated learning, we propose a distributed stochastic gradient descent (SGD) type algorithm that exploits the sparsity of the gradient, when possible, to reduce communication burden. At the heart of the algorithm is to use compressed sensing techniques for the compression of the local stochastic gradients at the device side; and at the server side, a sparse approximation of the global stochastic gradient is recovered from the noisy aggregated compressed local gradients. We conduct theoretical analysis on the convergence of our algorithm in the presence of noise perturbation incurred by the communication channels, and also conduct numerical experiments to corroborate its effectiveness.
Why Do the Quantum Observables Form a Jordan Operator Algebra?

description: The Jordan algebra structure of the bounded real quantum observables was recognized already in the early days of quantum mechanics. While there are plausible reasons for most parts of this structure, the existence of the distributive nonassociative multiplication operation is hard to justify from a physical or statistical point of view. Considering the non-Boolean extension of classical probabilities, presented in a recent paper, it is shown in this paper that such a multiplication operation can be derived from certain properties of the conditional probabilities and the observables, i.e., from postulates with a clear statistical interpretation. The well-known close relation between Jordan operator algebras and C*-algebras then provides the connection to the quantum-mechanical Hilbert space formalism, thus resulting in a novel axiomatic approach to general quantum mechanics that includes the types II and III von Neumann algebras.

description: We report the results of a 30 ks Chandra ACIS-S observation of the isolated compact object 1RXS J141256.0+792204 (Calvera). The X-ray spectrum is adequately described by an absorbed neutron star hydrogen atmosphere model with an effective temperature at infinity of 88.3 +/- 0.8 eV and radiation radius at infinity of 4.1 +/- 0.1 km/kpc. The best-fit blackbody spectrum yields parameters consistent with previous measurements; although the fit itself is not statistically acceptable, systematic uncertainties in the pile-up correction may contribute to this. We find marginal evidence for narrow spectral features in the X-ray spectrum between 0.3 and 1.0 keV. In one interpretation, we find evidence at 81%-confidence for an absorption edge at 0.64 (+0.08) (-0.06) keV with an equivalent width of ~70 eV; if this feature is real, it is reminiscent of features seen in the isolated neutron stars RX J1605.3+3249, RX J0720.4-3125, and 1RXS J130848.6+212708 (RBS 1223). In an alternative approach, we find evidence at 88%-confidence for an unresolved emission line at energy 0.53 +/- 0.02 keV, with an equivalent width of ~28 eV; the interpretation of this feature, if real, is uncertain. We search for coherent pulsations up to the Nyquist frequency of 1.13 Hz and set an upper limit of 8.0% rms on the strength of any such modulation. We derive an improved position for the source and set the most rigorous limits to-date on any associated extended emission on arcsecond scales. Our analysis confirms the basic picture of Calvera as the first isolated compact object in the ROSAT/Bright Source Catalog discovered in six years, the hottest such object known, and an intriguing target for multiwavelength study.

description: This paper considers a generalization of Gaussian random field with covariance function of Whittle-Mat$\acute{\text{e}}$rn family. Such a random field can be obtained as the solution to the fractional stochastic differential equation with two fractional orders. Asymptotic properties of the covariance functions belonging to this generalized Whittle-Mat$\acute{\text{e}}$rn family are studied, which are used to deduce the sample path properties of the random field. The Whittle-Mat$\acute{\text{e}}$rn field has been widely used in modeling geostatistical data such as sea beam data, wind speed, field temperature and soil data. In this article we show that generalized Whittle-Mat$\acute{\text{e}}$rn field provides a more flexible model for wind speed data.

description: We report on the charge-ordered structure of LiRh2O4 arising below the metal-insulator transition at 170 K. Structural studies using synchrotron X-rays have revealed that the charge-ordered states of Rh3+ and Rh4+ with dimerization are realized in the low-temperature phase below 170 K. Although the low-temperature ground state resembles that of CuIr2S4, a charge ordering pattern satisfying the Anderson condition is realized in LiRh2O4. Based on structural information such as the short-range order of dimers appearing above the transition temperature and the weakening of the correlation between rhodium one-dimensional chains appearing in the crystal structure, we argue that the Coulomb interaction plays an important role in determining the charge ordering patterns.

description: Σκοπός της παρούσας έρευνας είναι η μελέτη και καταγραφή των συγκριτικών πλεονεκτημάτων του νησιού της Κω στο πλαίσιο επανεξέτασης του branding (δηλαδή στο πλαίσιο του rebranding) για το νησί της Κω. Ο κύριος πυλώνας της έρευνας είναι αρχικά να αξιολογηθεί το υπάρχον branding του νησιού και έπειτα κατά πόσο η γαστρονομία, ο αγροτουρισμός καθώς και τα σημεία οικολογικής αισθητικής θα μπορούσαν να ενσωματωθούν στην εικόνα του νησιού και να αξιοποιηθούν στο πλαίσιο ενός αποτελεσματικού rebranding. Έπειτα, εξετάτηκε κατά πόσο διαφοροποιούνται οι απαντήσεις στα παραπάνω ερωτήματα σύμφωνα με τις επιμέρους ομάδες των ερωτώμενων, όπως προκύπτουν βάσει της ηλικίας τους, του μορφωτικού τους επιπέδου και του επαγγέλματός τους.
description: The purpose of this research is to study and record the assets of the island of Kos and consequently their exploitation. The main pillar of the research is first to evaluate the existing branding of the island and then the extent in which gastronomy, agrotourism and ecological aesthetics could be integrated into the island's image and exploited in the context of an effective rebranding. Then, it was examined whether the answers to the above questions differ according to the individual groups of respondents, as derived from their age, educational level and profession.

description: The vacuum fluctuation (VF) effects on asymmetric nuclear matter are investigated. Masses of nucleons and mesons are modified in the nuclear medium by calculating the loop-diagram corrections and the density dependence of hadron masses is obtained. The relativistic Lagrangian density with the isovector scalar $δ$ meson is used to calculate the nuclear equation of state (EOS) in the framework of the relativistic mean-field (RMF) approach, the effects of the in-medium hadron masses on the properties of neutron stars are finally studied. With the inclusion of the VF corrections, the nuclear EOS becomes softer and the neutron star masses are reduced.

description: The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companion star is veiled by other source of optical emission. Assessing this "veiling" effect is critical to the black hole mass measurement. Here in this work, we carry out a strictly simultaneous spectroscopic and photometric campaign on the prototype of black hole low-mass X-ray binary A0620-00. We find that for each observation epoch, the extra optical flux beyond a pure ellipsoidal modulation is positively correlated with the fraction of veiling emission, indicating the accretion disk contributes most of the non-ellipsoidal variations. Meanwhile, we also obtain a K2V spectral classification of the companion, as well as the measurements of the companion's rotational velocity $v \sin i = 83.8\pm1.9$ km s$^{-1}$ and the mass ratio between the companion and the black hole $q=0.063\pm0.004$.

The Role of Color-Magnetic Monopoles in a Gluonic Plasma

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The role of color-magnetic monopoles in a pure gauge plasma at high temperature $T>2T_c$ is considered. In this temperature regime, monopoles can be considered heavy, rare objects embedded into matter consisting mostly of the usual "electric" quasiparticles, quarks and gluons. The gluon-monopole scattering is found to hardly influence thermodynamic quantities, yet it produces a large transport cross section, significantly exceeding that for pQCD gluon-gluon scattering up to quite high $T$. This mechanism keeps viscosity small enough for hydrodynamics to work at LHC.

description: Metaheuristic and self-organizing criticality (SOC) could contribute to robust computation under perturbed environments. Implementing a logic gate in a computing system in a critical state is one of the intriguing ways to study the role of metaheuristics and SOCs. Here, we study the behavior of cellular automaton, game of life (GL), in asynchronous updating and implement probabilistic logic gates by using asynchronous GL. We find that asynchronous GL shows a phase transition, that the density of the state of 1 decays with the power law at the critical point, and that systems at the critical point have the most computability in asynchronous GL. We implement AND and OR gates in asynchronous GL with criticality, which shows good performance. Since tuning perturbations play an essential role in operating logic gates, our study reveals the interference between manipulation and perturbation in probabilistic logic gates.

description: We report on neutron-scattering results on the impact of a magnetic field on stripe order in the cuprate La$_{1.875}$Ba$_{0.125}$CuO$_4$. It is found that a 7 T magnetic field applied along the {\it c} axis causes a small but finite enhancement of the spin-order peak intensity and has no observable effect on the peak width. Inelastic neutron-scattering measurements indicate that the low-energy magnetic excitations are not affected by the field, within experimental error. In particular, the small energy gap that was recently reported is still present at low temperature in the applied field. In addition, we find that the spin-correlation length along the antiferromagnetic stripes is greater than that perpendicular to them.

description: Recent measurements of cosmic-ray electron and positron fluxes by PAMELA and ATIC experiments may indicate the existence of annihilating dark matter with large annihilation cross section. We show that the dark matter annihilation in the big-bang nucleosynthesis epoch affects the light element abundances, and it gives stringent constraints on such annihilating dark matter scenarios for the case of hadronic annihilation. Constraints on leptonically annihilating dark matter models are less severer.

Fernando Zamora: un poeta raro
Creators: name: Alonso, Julián
Publisher: name: Università degli Studi di Milano
Year: 2014

description: Fernando Zamora no es solo un poeta que pinta o un pintor que escribe, sino un creador en el más amplio sentido de la palabra, un espíritu libre y fronterizo que no se deja influenciar por los clichés al uso en cuanto a lo que es y no es Arte, ni por la obsesiva sistematización que de las diferentes disciplinas trata de establecer la crítica tradicional. Fernando Zamora pinta, escribe, pasea, reflexiona pero es mucho más que eso, porque no se entendería el todo sin sus partes. Para inspirarse necesita pasear, recorrer campo y caminos, alejarse de la civilización pero para completar su tarea también precisa regresar a territorio conocido y pisar tierra firme, por más que vuelva siempre cargado de ideas y objetos perdidos o desahuciados. Transita por la frontera, a veces de un lado, a veces del otro, las más con un pie en cada orilla, y así surgen unas obras que pocas veces podemos —ni él mismo puede— determinar a qué territorio pertenecen, pero ahí están, afirmando su existencia y la de su creador, un poeta raro, sin duda, pero también un artista con mayúsculas.

description: We demonstrate that collective motion of interfacial fluctuations can occur at the interface between two coexisting thermodynamic phases. Based on computer simulation results for driven diffusive Ising and Blume-Capel models, we conjecture that the thermal capillary waves at a planar interface travel along the interface if the lateral order parameter current j_op(y) is an odd function of the distance y from the interface and hence possesses opposite directions in the two phases. Such motion does not occur if j_op(y) is an even function of y. A discrete Gaussian interface model with effective dynamics exhibits similiar transport phenomena but with a simpler dispersion relation. These findings open up avenues for controlled interfacial transport on the nanoscale.
