description: We calculate the weak interaction rates of selected light nuclei during the epoch of Big Bang Nucleosynthesis (BBN), and we assess the impact of these rates on nuclear abundance flow histories and on final light element abundance yields. We consider electron and electron antineutrino captures on 3He and 7Be, and the reverse processes of positron capture and electron neutrino capture on 3H and 7Li. We also compute the rates of positron and electron neutrino capture on 6He. We calculate beta and positron decay transitions where appropriate. As expected, the final standard BBN abundance yields are little affected by addition of these weak processes, though there can be slight alterations of nuclear flow histories. However, non-standard BBN scenarios, e.g., those involving out of equilibrium particle decay with energetic final state neutrinos, may be affected by these processes.

description: Il contributo è volto a indagare le funzioni di alcune “figure sonore” – legate dunque a un immaginario musicale – nella letteratura di Calvino. Si riscontra la persistenza tematica di alcuni motivi testuali legati all’ascolto, disseminati dagli scritti autobiografici di Passaggi obbligati fino alla raccolta de I cinque sensi, passando per le Cosmicomiche e per alcuni capitali contributi critici come I livelli della realtà in letteratura. L’immaginario sonoro appare fittamente connesso ad alcuni elementi cardine della parabola letteraria di Calvino, quali la prospettiva congetturale, le memorie familiari e di guerra, i mondi possibili e invisibili, la sfida al labirinto.
description: The aim of the essay is to examines the functions of some “sonorous figures” – therefore linked to a musical imagination – in Calvino’s literature. The thematic persistence of some textual motifs related to listening is to be found in the autobiographical narratives of Passaggi obbligati, as in the collection of I cinque sensi, or Cosmicomiche and some important critical contribution as I livelli della realtà in letteratura. The sonorous imaginary appears closely connected to some key elements of Calvino’s literature, such as conjectural perspective, family and war memories, possible and invisible worlds, the challenge to the labyrinth.

description: Nei Dialoghi con Leucò di Cesare Pavese il tema del rapporto tra uomini, dèi e destino costituisce uno dei concetti-chiave dell’opera, ma lega in particolare i dialoghi I ciechi e La strada, che hanno come protagonista Edipo, il mitico re di Tebe inconsapevole assassino del padre e sposo della propria madre. Nel primo, l’indovino cieco Tiresia predice al giovane e ignaro sovrano ciò che sta per accadere, ma la sua profezia ambigua cade nel vuoto. Nel secondo Edipo, accecatosi per sfuggire l’orrore della propria mostruosa condizione, lamenta di aver subito il destino senza nessuna possibilità di scelta, ma il suo interlocutore, un mendicante, gli rammenta che tale sorte accomuna tutti gli uomini. Un individuo, con le sue azioni e i suoi discorsi, può però cambiare il futuro degli altri. Gli dèi, il destino, gli uomini, i discorsi sono quindi interconnessi, ma l’autonomia umana consiste proprio nella facoltà di ricordare, raccontare e fare poesia, la forma più alta di libertà possibile.
description: The relationship between men, gods and destiny is one of the main subjects of Cesate Pavese’s Dialoghi con Leucò. Particularly, this idea links the dialogues I ciechi and La strada, whose protagonist is Oedipus, the mytical king of Thebes, inconscious murderer of his father and husband of his mother. In the first dialogue, the blind seer Tiresias predicts to the young and inconscious king the incoming fate, but his ambiguous prediction comes to nothing. In the second Oedipus, who has blinded himself because the horror of his monstruos condition, says that he never chose his destiny, but his interlocutor remind to him that all the man have the same destiny, but somebody can change another man’s life with his speech and his acts. Therefore, men, gods, destiny and words are connected, but human autonomy is based on the skill of remember, tell the stories and make verses, the best shape of human freedom.

description: Intel Ethernet Flow Director is an advanced network interface card (NIC) technology. It provides the benefits of parallel receive processing in multiprocessing environments and can automatically steer incoming network data to the same core on which its application process resides. However, our analysis and experiments show that Flow Director cannot guarantee in-order packet delivery in multiprocessing environments. Packet reordering causes various negative impacts. E.g., TCP performs poorly with severe packet reordering. In this paper, we use a simplified model to analyze why Flow Director can cause packet reordering. Our experiments verify our analysis.

description: We show that the spectrum of an ensemble of two-level systems can be broadened through `resetting' discrete fluctuations, in contrast to the well-known motional-narrowing effect. We establish that the condition for the onset of motional broadening is that the ensemble frequency distribution has heavy tails with a diverging first moment. We find that the asymptotic motional-broadened lineshape is a Lorentzian, and derive an expression for its width. We explain why motional broadening persists up to some fluctuation rate, even when there is a physical upper cutoff to the frequency distribution.

description: This paper is an attempt to incorporate the idea of spiking neural P systems as an early seed into the area of Operating System Design, regarding their capability to solve some classical computer science problems. It is reflecting the power of such systems to simulate well known parallel computational models, like logic gates, arithmetic operation, and sorting. In these devices, the time (when the neurons fire and/or spike) plays an essential role. For instance, the result of a computation is the time between the moments when a specified neuron spikes. Seen as number computing devices, SN P systems are shown to be computationally complete, and with such capabilities, arithmetic operations, logic, and timing, some first steps could be taken towards an OS design.

description: Electron spins in solids are promising candidates for quantum memories for superconducting qubits because they can have long coherence times, large collective couplings, and many quantum bits can be encoded into the spin-waves of a single ensemble. We demonstrate the coupling of electron spin ensembles to a superconducting transmission-line resonator at coupling strengths greatly exceeding the cavity decay rate and comparable to spin linewidth. We also use the enhanced coupling afforded by the small cross-section of the transmission line to perform broadband spectroscopy of ruby at millikelvin temperatures at low powers. In addition, we observe hyperfine structure in diamond P1 centers and time domain saturation-relaxation of the spins.

The relative importance of calving and surface ablation at a lacustrine terminating glacier : a detailed assessment of ice loss at Bridge Glacier, British Columbia
Creators: name: Chernos, Matthew
Publisher: name: University of British Columbia
Year: 2014

description: Bridge Glacier is a lacustrine calving glacier located in the southern Coast Mountains and terminates in a 6.2 km² proglacial lake. The glacier has retreated more than 3.55 km up-valley since 1984, the majority of the retreat having occurred since 2003. While surface melt may have contributed to the retreat, calving allowed for an additional annual volume of ice loss. The relative contributions from surface melt and calving to the total volume of ice loss is examined for the 2013 melt season. Surface melt is quantified using on-glacier meteorological data to drive a distributed energy balance model. The calving flux is quantified using field measurements of lake bathymetry, terminus area change, and ice thickness. Calving flux estimates are completed by daily measurements of terminus surface velocity derived from manual feature tracking using oblique time lapse camera imagery. Calving accounts for 23% of the total ice loss in the 2013 melt season, suggesting that surface melt is the main driver of mass loss at Bridge Glacier. Data from the 2013 field season is used to inform historical calving flux and surface melt estimates from 1984 to 2013. The calving flux is minor until 1991, at which point the glacier terminus achieves flotation, and begins to discharge large tabular icebergs. Calving was characterized by large, multi-annual retreats, alternating with periods of relative stability. The calving flux peaked from 2005 to 2010, when it was roughly equal to the mass loss due to surface melt. Calving was a much smaller contributor of mass loss from Bridge Glacier, except for a transient high-calving period in the late 2000s. Looking forward, Bridge Glacier will retreat into shallower water where the terminus will no longer float, and calving losses should decrease substantially. Although calving losses will become an increasingly minor portion of the mass balance, future retreat is expected at Bridge Glacier due to a legacy of dynamic thinning brought about by its transient calving phase.

description: We investigate time variations and detailed spatial structures of X-ray synchrotron emission in the northeastern limb of SN 1006, using two Chandra observations taken in 2000 and 2008. We extract spectra from a number of small (about 10") regions. After taking account of proper motion and isolating the synchrotron from the thermal emission, we study time variations in the synchrotron emission in the small regions. We find that there are no regions showing strong flux variations. Our analysis shows an apparent flux decline in the overall synchrotron flux of about 4% at high energies, but we suspect that this is mostly a calibration effect, and that flux is actually constant to about 1%. This is much less than the variation found in other remnants where it was used to infer magnetic-field strengths up to 1 mG. We attribute the lack of variability to the smoothness of the synchrotron morphology, in contrast to the small-scale knots found to be variable in other remnants. The smoothness is to be expected for a Type Ia remnant encountering uniform material. Finally we find a spatial correlation between the flux and the cut-off frequency in synchrotron emission. The simplest interpretation is that the cut-off frequency depends on the magnetic-field strength. This would require that the maximum energy of accelerated electrons is not limited by synchrotron losses, but by some other effect. Alternatively, the rate of particle injection and acceleration may vary due to some effect not yet accounted for, such as a dependence on shock obliquity.

For bound states, we introduce an asymptotic field for each (stable) bound state. We choose the nonrelativistic hydrogen atom as an example to illustrate the method. Future work will apply this N-quantum approach to relativistic theories that include bound states in motion.

Chromium: NLTE abundances in metal-poor stars and nucleosynthesis in the Galaxy

Publisher: name: arXiv
Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Aims. We investigate statistical equilibrium of Cr in the atmospheres of late-type stars to show whether the systematic abundance discrepancy between Cr I and Cr II lines, as often encountered in the literature, is due to deviations from LTE. Furthermore, we attempt to interpret the NLTE trend of [Cr/Fe] with [Fe/H] using chemical evolution models for the solar neighborhood. Methods. NLTE calculations are performed for the model of Cr atom, comprising 340 levels and 6806 transitions in total. We make use of the quantum-mechanical photoionization cross-sections of Nahar (2009) and investigate sensitivity of the model to uncertain cross-sections for H I collisions. NLTE line formation is performed for the MAFAGS-ODF model atmospheres of the Sun and 10 metal-poor stars with -3.2 < [Fe/H] < -0.5, and abundances of Cr are derived by comparison of the synthetic and observed flux spectra. Results. We achieve good ionization equilibrium of Cr for the models with different stellar parameters, if inelastic collisions with H I atoms are neglected. The solar NLTE abundance based on Cr I lines is 5.74 dex with σ = 0.05 dex; it is \sim 0.1 higher than the LTE abundance. For the metal-poor stars, the NLTE abundance corrections to Cr I lines range from +0.3 to +0.5 dex. The resulting [Cr/Fe] ratio is roughly solar for the range of metallicities analyzed here, which is consistent with current views on production of these iron peak elements in supernovae. Conclusions. The tendency of Cr to become deficient with respect to Fe in metal-poor stars is an artifact due to neglect of NLTE effects in the line formation of Cr I, and it has no relation to peculiar physical conditions in the Galactic ISM or deficiencies of nucleosynthesis theory.

Evolution of the Late Cretaceous Whistler Au-(Cu) porphyry corridor and magmatic-hydrothermal system, Kahiltna terrane, southwestern Alaska, USA
Creators: name: Hames, Benjamin P.
Publisher: name: University of British Columbia
Year: 2014

description: The Whistler Corridor is located in the Alaskan Range 150 km northwest of Anchorage. Hosted by the regionally extensive Kahiltna flysch terrane, the Whistler Igneous Suite (WIS) volcano-magmatic sequence is calc-alkalic, metaluminous, and exhibits an arc related trace element signature. Extrusive rocks comprise andesite flows, volcaniclastic rocks, and hypabyssal dykes and sills. Intrusive rocks are dioritic with two major phases. An initial phase associated with porphyry mineralisation was dated by zircon U-Pb (CA-TIMS) at 76.4 ± 0.3 Ma. A later unmineralised phase had previously been determined by hornblende Ar-Ar at 75.5 ± 0.3 Ma. Mineralised diorite exhibits Nb/Y ratios >1.1 distinct from unmineralised diorite (Nb/Y<1.1). Of several porphyry occurrences the largest is the Whistler deposit hosting an indicated and inferred resource of 3.13 Moz Au and 769 Mlbs Cu. The main Au-Cu zone is characterised by feldspar-stable albite-magnetite (sodic-ferric) and K-feldspar-magnetite (potassic) alteration associated with magnetite (M-) and quartz (A-, B-) veins. High-temperature albitic alteration was characterised using energy dispersive spectroscopic (EDS) analyses of previously unidentified alteration. A peripheral zone of quartz-sericite-pyrite (phyllic) alteration is associated with quartz (D1-3) and pyrite (D4-5) veins. Sphalerite and galena in D3-veins define an overprinting Zn-Pb zone. An intermineral intrusive phase in the core of the deposit is associated with a magmatic-hydrothermal breccia hosting the highest-grade Cu-Au zone. Locally, shallow-level equivalent of D3-veins comprise colloform and crustiform textured intermediate-sulphidation Pb-Zn-Ag-Au veins. Sulphide δ³⁴S isotopes range from 0.4-7.7‰ (xˉ=3.8‰; σ=1.3‰). δ³⁴S in M/A-veins is 1.7‰; B-veins 3.4‰; D1-3 veins 3.7‰; D4-5 veins 4.9‰; and E-veins 6.5‰. δ³⁴S values increase temporally due to the preferential fractionation of ³⁴S into increasingly acidic, reduced fluids. Chlorite and sericite overprint feldspar-stable alteration. Short-wave infrared spectroscopy and X-Ray diffraction demonstrate higher temperature, more crystalline sericite in phyllic than chlorite-sericite alteration. A lack of a negative Nb-Ta anomaly, consistently positive sulphide δ³⁴S isotopes, and oxidised magnetite-series igneous rocks suggest a lack of crustal contamination. Thus, at ca. 76 Ma Whistler represents the earliest, least crustally contaminated, porphyry occurrences of the Late Cretaceous magmatic epoch in SW Alaska.

In particular, they allow to detect a correlation length that is not measurable with standard correlation functions.

Determining the initial helium abundance of the Sun

Publisher: name: arXiv

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We determine the dependence of the initial helium abundance and the present-day helium abundance in the convective envelope of solar models ($\yim$ and $\ysm$ respectively) on the parameters that are used to construct the models. We do so by using reference standard solar models to compute the power-law coefficients of the dependence of $\yim$ and $\ysm$ on the input parameters. We use these dependencies to determine the correlation between $\yim$ and $\ysm$ and use this correlation to eliminate uncertainties in $\yim$ from all solar model input parameters except the microscopic diffusion rate. We find an expression for $\yim$ that depends only on $\ysm$ and the diffusion rate. By adopting the helioseismic determination of solar surface helium abundance, $\ysms= 0.2485\pm0.0035$, and an uncertainty of 20% for the diffusion rate, we find that the initial solar helium abundance, $\yims$, is $0.278 \pm 0.006$ independently of the reference standard solar models (and particularly on adopted the solar abundances) used in the derivation of the correlation between $\yim$ and $\ysm$. When non-standard solar models with extra mixing are used, then we derive $\yims = 0.273 \pm 0.006$. In both cases, the derived $\yims$ value is higher than that directly derived from solar model calibrations when the low metalicity solar abundances (e.g. by Asplund et al.) are adopted in the models.

description: The quick and precise localization of GRBs by the Swift telescope allows the early evolution of the afterglow light curve to be captured by ground-based telescopes. With GROND measurements we can investigate the optical/near-infrared light curve of the afterglow of gamma-ray burst 080413B in the context of late rebrightening. Multi-wavelength follow-up observations were performed on the afterglow of GRB 080413B. X-ray emission was detected by the X-ray telescope onboard the Swift satellite and obtained from the public archive. Optical and near-infrared photometry was performed with the seven-channel imager GROND mounted at the MPG/ESO 2.2 m telescope and additionally with the REM telescope, both in La Silla, Chile. The light curve model was constructed using the obtained broad-band data. The broad-band light curve of the afterglow of GRB 080413B is well fitted with an on-axis two-component jet model. The narrow ultra-relativistic jet is responsible for the initial decay, while the rise of the moderately relativistic wider jet near its deceleration time is the cause of the rebrightening of the light curve. The later evolution of the optical/NIR light curve is then dominated by the wide component, the signature of which is almost negligible in the X-ray wavelengths. These components have opening angles of theta(narrow) ~1.7 degrees and theta(wide) ~9 degrees, and Lorentz factors of Gamma(narrow) >188 and Gamma(wide) ~18.5. We calculated the beaming-corrected energy release to be 7.9 x 10^48 erg.

We examine the benefits of hybrid quantum bits (qubits) in the solid state that are based on coupling electron spins to nuclear spin, electron charge, optical photons, and superconducting qubits. These benefits include the coherent storage of qubits for times exceeding seconds, fast qubit manipulation, single qubit measurement, and scalable methods for entangling spatially separated matter-based qubits. In this way, the key strengths of different physical qubit implementations are brought together, laying the foundation for practical solid-state quantum technologies.

description: Il saggio ripercorre l’intenso e controverso rapporto intercorso fra Vittorio Gassman e la stampa teatrale, in particolare, negli anni che vanno dall’enorme successo di pubblico dell’Amleto (1952) al ciclo di spettacoli che copre gli anni dal 1955 al 1958. Sempre in bilico fra la profonda attitudine introspettiva ed un desiderio innato di compiacere il pubblico, Gassman intesse uno strettissimo legame con la stampa, arrivando a contribuire egli stesso al racconto di sé, attraverso interventi e rubriche in quotidiani e riviste. Protagonista del primo fenomeno di ‘neodivismo’ del dopoguerra incarna infatti un divismo teatrale di nuovo genere, trovandosi (sin dalle sue prime prove) al centro di celebrazioni ed elogi, come di critiche feroci.
description: The essay traces the intense and controversial relationship between Vittorio Gassman and the theatrical press, in particular, in the years from the enormous public success of Hamlet (1952) to the cycle of performances covering the years from 1955 to 1958. Always on the borderline between a profoundly introspective attitude and an innate desire to please the public, Gassman forged a close bond with the press, even contributing to the story of himself, through interventions and columns in newspapers and magazines. Protagonist of the first phenomenon of 'neo-divorism' of the postwar period, he embodies in fact a new kind of theatrical stardom, finding himself (since his first tests) at the center of celebrations and praise, as well as fierce criticism.

description: L’ingresso della drammaturgia di Pirandello nel circuito dei teatri di lingua tedesca è segnato dal debutto a Vienna, nell’aprile 1924, dei Sei personaggi in cerca d’autore (1921). Stimolato verosimilmente da quella prima messinscena, qualche mese dopo il regista più famoso all’epoca, Max Reinhardt, allestì l’opera a Berlino, inaugurando la cosiddetta “moda” di Pirandello in Germania. L’articolo, volto a sondare le reazioni della critica teatrale ai due debutti, austriaco e tedesco, riflette sulle riserve espresse allora dai recensori – anche illustri – nei confronti dello scrittore italiano. La natura degli appunti critici apre una riflessione interessante sulla reale percezione della “novità” della drammaturgia pirandelliana, meritevole di approfondimenti futuri.
description: Pirandello’s dramaturgy entered the German-language theater circuit with the April 1924 Vienna debut of his Six Characters in Search of an Author (1921). Probably struck by that first staging, a few months later the most famous director of the time, Max Reinhardt, staged the work in Berlin, inaugurating the so-called Pirandello “mode’” in Germany. This article probes the reactions of theater critics to the two debuts, the Austrian and the German one, reflecting on the reservations which the reviewers of the day – illustrious ones included – expressed towards the Italian playwright. The attitudes expressed in their critical notes provide food for an interesting reflection on the real perception of the “novelty” of Pirandello’s dramaturgy, worthy of future study

A study on the coupled effects of solute and grain size on the work hardening of fine- grained FCC alloys
Creators: name: Shadkam, Ashkan
Publisher: name: University of British Columbia
Year: 2014

description: This thesis develops a physically based model for the work hardening of model (pure or solute strengthened) FCC alloys having grain sizes of between 2 μm and 100 μm. This model builds on a previous study of Sinclair et al. (2006) on fine-grained pure Cu and extends it to Cu16at%Ni, Cu50at%Ni and Cu1.5at%Al alloys. Through careful and systematic mechanical testing coupled with microstructural observations several basic hypotheses were tested. The yielding behaviour of fine-grained materials showed an extension of the elasto-plastic transition (over the generally accepted 0.002 offset strain) with decreasing grain size and increasing solute content. This resulted in Hall-Petch plots which showed that the grain size effect was more pronounced with increasing solute content. In all of the materials tested with a sufficiently fine grain size, the stress-strain plots showed an inflection (i.e. region of a low work hardening or “plateau”). While the work hardening rate dropped significantly in this portion of the test, image correlation was used to show that the drop in work hardening was not sufficient to cause strain localization. The stress-strain plots were differentiated and work hardening behaviour was analyzed using a Kocks-Mecking model. An important observation was that with increasing solute content from pure Cu to Cu50at%Ni, a grain size dependent separation between the work hardening plots appeared for tests performed at room temperature. This observation was initially hypothesized to be due to backstresses as proposed in the original model of Sinclair (Sinclair et al. 2006). This idea was tested using strain-rate sensitivity experiments. Strain-rate sensitivity tests showed that a single mechanism (forest hardening) controls the work hardening behaviour beyond the initial few percentage of straining. To unify all these experimental observations in a self-consistent work hardening model, the original Sinclair model was modified through the addition of a new variable, n*f , which accounts for additional dislocation storage by the forest dislocations blocked at grain boundaries. It was hypothesized that the effects of dislocation/grain boundary interactions on screening/annihilation of dislocations could be used to capture the initial high rate sensitivity at the “plateau” in the stress-strain curve of fine grained alloys.
Rare seahorses have big implications for small fishes in bycatch

description: The incidental capture of marine organisms is a critical area of concern in fisheries management, and despite the dominance of small fishes in bycatch biomass around the globe, we know little about the impacts of bycatch on these small fishes. Here, I focus on one such small fish taxon, the seahorses (Hippocampus spp.). Seahorse populations are typically patchy, and they have a specialized life history that makes them more likely to be vulnerable to overfishing. I assessed the impacts of nonselective gear on seahorses in one country by examining potential impacts for three species in peninsular Malaysia. I also assessed the impacts of seahorse bycatch globally, by synthesizing a global array of studies. For my national analysis, I used data-poor assessment methods to estimate life history parameters for three species of seahorse in peninsular Malaysia (Chapter 2). For my global analysis, I extracted data found in a published and unpublished reports to generate a synthesis of global seahorse bycatch (Chapter 3). Nationally, my findings indicate the potential for overfishing for one species found in the southwest region of the peninsular Malaysia. Globally, my synthesis revealed that all fishing gears obtained seahorses in bycatch, but at very low rates of capture per vessel per day. Across all countries, fishers characterized seahorses as relatively rare in their bycatch and declining in catches. One key finding was that low CPUE scaled up to tens of millions of seahorses obtained globally as bycatch each year. My results address the impacts of bycatch on seahorses and discuss the implications for other small bycaught fish species, especially those that are demersal or rare.

description: In contrast to planets with masses similar to that of Jupiter and higher, the bulk compositions of planets in the so-called super-Earth regime cannot be uniquely determined from a mass and radius measurement alone. For these planets, there is a degeneracy between the mass and composition of the interior and a possible atmosphere in theoretical models. The recently discovered transiting super-Earth GJ1214b is one example of this problem. Three distinct models for the planet that are consistent with its mass and radius have been suggested, and breaking the degeneracy between these models requires obtaining constraints on the planet's atmospheric composition. Here we report a ground-based measurement of the transmission spectrum of GJ1214b between 780 and 1000 nm. The lack of features in this spectrum rules out cloud-free atmospheres composed primarily of hydrogen at 4.9 sigma confidence. If the planet's atmosphere is hydrogen-dominated, then it must contain clouds or hazes that are optically thick at the observed wavelengths at pressures less than 200 mbar. Alternatively, the featureless transmission spectrum is also consistent with the presence of a dense water vapor atmosphere.

description: Embedded clusters are formed in molecular clouds where massive stars can produce HII regions. The detailed embedded-open cluster evolutionary connection as well as the origin of associations are yet to be unveiled. There appears to be a high infant mortality rate among embedded clusters and the few survivors evolve to open clusters. We study the colour-magnitude diagrams and structure of the star clusters related to the Sh2-132 HII region using the 2MASS database. Cluster fundamental and structural parameters are determined via MS and PMS isochrones and stellar radial density profiles. We report the discovery of four clusters. One of them is projected a few diameters away from the optical cluster Teutsch\,127 and appears to be deeply embedded, seen only in the infrared. Evidence is found that we are witnessing the dynamical transition from an embedded to an open cluster. An additional cluster is also close to Teutsch\,127 and might be associated with a bow-shock. We also study the CMD and structure of the open cluster Berkeley\,94 in Sh2-132 and a new cluster which is projected in the outskirts of the complex. Finally, we searched for star clusters around the two known Wolf-Rayet stars in the complex. One of them appears to be related to a compact cluster. Finally, the present analyses suggest early dynamical evolution for young star clusters.

description: Heisenberg's uncertainty principle provides a fundamental limitation on an observer's ability to simultaneously predict the outcome when one of two measurements is performed on a quantum system. However, if the observer has access to a particle (stored in a quantum memory) which is entangled with the system, his uncertainty is generally reduced. This effect has recently been quantified by Berta et al. [Nature Physics 6, 659 (2010)] in a new, more general uncertainty relation, formulated in terms of entropies. Using entangled photon pairs, an optical delay line serving as a quantum memory and fast, active feed-forward we experimentally probe the validity of this new relation. The behaviour we find agrees with the predictions of quantum theory and satisfies the new uncertainty relation. In particular, we find lower uncertainties about the measurement outcomes than would be possible without the entangled particle. This shows not only that the reduction in uncertainty enabled by entanglement can be significant in practice, but also demonstrates the use of the inequality to witness entanglement.

description: Nuclide production cross sections measured at ITEP for the targets of nat-Cr, 56-Fe, nat-Ni, 93-Nb, 181-Ta, nat-W, nat-Pb, 209-Bi irradiated by protons with energies from 40 to 2600 MeV were used to estimate the predictive accuracy of several popular high-energy transport codes. A general agreement of the ITEP data with the data obtained by other groups, including the numerous GSI data measured by the inverse kinematics method was found. Simulations of the measured data were performed with the MCNPX (Bertini and ISABEL options), CEM03.02, INCL4.2+ABLA, INCL4.5+ABLA07, PHITS, and CASCADE.07 codes. Deviation factors between the calculated and experimental cross sections have been estimated for each target and for the whole energy range covered by our measurements. Two-dimensional diagrams of deviation factor values were produced for estimating the predictive power of every code for intermediate, not measured masses of nuclei-targets and bombarding energies of protons. Further improvements of all tested here codes are recommended. In addition, new measurements at ITEP of nuclide yields from a 208-Pb target irradiated by 500 MeV protons are presented. A good agreement between these new data and the GSI measurements obtained by the inverse kinematics method was found

description: Il contributo verte sul rapporto fra Ettore Petrolini e la maschera di Pulcinella, ossia sul recupero delle prassi della Commedia dell’Arte da parte del grande comico romano e sulle modalità di inveramento attorico di tale tradizione, con particolare riguardo al medium cinematografico e al Nerone (1930) di Blasetti. La pellicola Cines, prodotto di lancio delle meraviglie del sonoro, altro non è che un surrogato del teatro, il calco di gesso del multiforme mondo artistico dell’attore, la sinopia rispetto all’affresco policromo e vivente del palcoscenico. Attraverso l’analisi di due inediti copioni e attraverso lo studio delle testimonianze sulla diffusione ottocentesca della farsa Pulcinella guardiano di donne, si esaminano i ripetuti incontri teatrali tra Petrolini e la maschera partenopea e se ne analizza il rilancio in formato filmico.

Falso mito

description: L’articolo ricostruisce le tappe fondamentali del processo politico di nazionalizzazione delle produzioni dei Teatri Imperiali durante il regno degli zar Alessandro III e Nicola II, mettendo a fuoco le cause che determinarono l’aspra contesa tra gli artisti occidentalisti pietroburghesi del Mondo dell’Arte e gli slavofilisti moscoviti del Circolo di Savva Mamontov. In questo contesto emerse la figura di Sergej Djagilev, di cui si ricostruiscono le complesse vicende in patria che lo portarono a cercare il riscatto all’estero, dove fiorì il falso mito dell’impresariocreatore dello spettacolo della sintesi delle arti. Esso è falso perché si fonda sull’appropiazione di meriti, sottratti indebitamente a coloro che ne furono i veri ideatori.
description: The article focuses on the fundamental stages of the productions nationalization political process in the Imperial Theatres under the Tsars Alexander III and Nicholas II. It clarifies the causes that led to the bitter dispute between the St. Petersburg Westernizers artists of the World of Art and the Moscow Slavophilists of Savva Mamontov’s Circle. In this context, the figure of Sergei Diaghilev emerged, whose complex events in Russia are reconstructed. Diaghilev sought redemption for his failed projects abroad. Here the false myth of the impresario-creator of the synthesis of the arts flourished. The myth is false because it is based on the appropriation of merits, unduly subtracted from those who were the true creators.

description: We study how the degree of symmetry in the couplings influences the performance of three mean field methods used for solving the direct and inverse problems for generalized Sherrington-Kirkpatrick models. In this context, the direct problem is predicting the potentially time-varying magnetizations. The three theories include the first and second order Plefka expansions, referred to as naive mean field (nMF) and TAP, respectively, and a mean field theory which is exact for fully asymmetric couplings. We call the last of these simply MF theory. We show that for the direct problem, nMF performs worse than the other two approximations, TAP outperforms MF when the coupling matrix is nearly symmetric, while MF works better when it is strongly asymmetric. For the inverse problem, MF performs better than both TAP and nMF, although an ad hoc adjustment of TAP can make it comparable to MF. For high temperatures the performance of TAP and MF approach each other.
