description: Il presente Dossier Ljubimov – Parte prima vuole essere il primo di una serie dedicata ad uno dei più eminenti artisti della seconda metà del XX secolo. Il regista russo (1917-2014), fondatore del mitico teatro "Na Taganke", indimenticabile isola di libertà degli anni '70 in URSSS, ha al suo attivo più di cento regie, tra messe in scena di prosa, poesia e opere liriche che la critica italiana incomprensibilmente ha trascurato. Tanto più se si considera che prima e dopo l'esilio forzato nel 1983, egli lavorò a lungo nel nostro paese, mettendo in scena ben 4 opere al Teatro alla Scala e successivamente dirigendo il maggio fiorentino. Presentiamo qui il regista a partire da materiali raccolti durante conversazioni personali avute con lui negli ultimi 15 anni della sua lunga vita.

The Russian director (1917-2014), founder of the legendary "Na Taganke" theatre, an unforgettable island of freedom in the USSR in the 1970s, has to his credit more than a hundred productions, including prose, poetry and opera that Italian critics have incomprehensibly overlooked. All the more so considering that before and after his forced exile in 1983, he worked in our country for a long time, staging no less than four operas at La Scala and later directing the Florentine May. Here we present the director from materials collected during personal conversations with him during the last 15 years of his long life

description: Gli spettacoli di Daniele Timpano raccontano o mettono in scena storie frammentarie e discontinue che si disgregano in intrecci senza fabula e che talora non approdano nemmeno a uno scioglimento finale. La disorganicità programmatica delle pièce dell’autore-attore riflette una concezione post-moderna della Storia, per cui al teatro è negata la possibilità di conoscere e comprendere un divenire storico che appare caotico e privo di certezze assolute. In questo consiste la principale differenza tra Timpano ed i vari narratori (Marco Paolini, Ascanio Celestini, ecc.) che negli ultimi trent’anni hanno utilizzato la scena come spazio/tempo deputato ad investigare e spiegare le aporie del presente o del passato prossimo.
description: Daniele Timpano’s shows tell or stage fragmentary and discontinuous stories that break up into plot sequences without a fabula and that sometimes do not even reach a final denouement. The intentional incoherence of the actor-author’s plays reflects a postmodern conception of History, so that the theatre is denied the possibility of knowing and understanding a historical process which is seemingly chaotic and without absolute certainties. This is the main difference between Timpano and the so called “narratori” (Marco Paolini, Ascanio Celestini, ecc.) who in the last thirty years have used the stage as a place and time to investigate and explain the contradictions of the present or of the recent past.

description: X-ray polarimetry promises to give qualitatively new information about high-energy sources. Examples of interesting source classes are binary black hole systems, rotation and accretion powered neutron stars, Microquasars, Active Galactic Nuclei and Gamma-Ray Bursts. Furthermore, X-ray polarimetry affords the possibility for testing fundamental physics, e.g. to observe signatures of light bending in the strong gravitational field of a black hole, to detect third order Quantum Electrodynamic effects in the magnetosphere of Magnetars, and to perform sensitive tests of Lorentz Invariance. In this paper we discuss scientific drivers of hard (>10 keV) X-ray polarimetry emphasizing how observations in the hard band can complement observations at lower energies (0.1 - 10 keV). Subsequently, we describe four different technical realizations of hard X-ray polarimeters suitable for small to medium sized space borne missions, and study their performance in the signal-dominated case based on Monte Carlo simulations. We end with confronting the instrument requirements for accomplishing the science goals with the capabilities of the four polarimeters.

description: Partendo dalla problematica definizione di “documentario di animazione” e dalle questioni che essa solleva sul rapporto tra realtà e disegno, questo saggio sostiene che Valzer con Bashir di Ari Folman può essere definito una “narrazione documentale”. In questo film, infatti, un processo di “autenticazione intermediale” sfrutta le possibilità creative e le risorse retoriche della finzionalità insieme a quelle testimoniali e referenziali del documentario con l’obiettivo di superare una rimozione traumatica. In questo modo Ari Folman tenta di costruire una memoria dei fatti narrati che sia critica e soggettiva, ma anche fortemente ancorata alla realtà.
description: Starting from the problematic definition of “animation documentary” and the questions it raises about the relationship between reality and drawing, this essay argues that Ari Folman's Waltz with Bashir can be defined as a “documentary narrative”. In this film, a process of "intermedial authentication" exploits the creative possibilities and rhetorical resources of fiction together with the testimonial and referential resources of documentary, aiming at overcoming a traumatic removal. In this way Ari Folman attempts to construct a memory of the facts narrated that is critical and subjective, as well as strongly anchored to reality.

subject: FOS: Economics and business

description: This study examines the latest literature on Japanese corporate governance with a view to identify the nature of current view of the Japanese corporate governance and thereby recognizes major contemporary issues to be handled. More specifically this study attempts to address three main empirical questions. (i) How far has the recent reform of corporate governance progressed? (ii) What factors determine a company's reform effort? And (iii) Do reforms actually improve the level of corporate performance? The results show an increasing trend of shifting the Japanese corporations toward the market model. There is a remarkable priority on shareholders and customers maintaining the emphasis on employees. Both executive officer system and outside director systems are being introduced widely, ensuring proper segregation between 'execution' and 'monitoring' instead of traditional seniority based promotions within the corporation. The relationship between governance reforms and corporate performance is positively significant and corporate governance reforms are contributing to improve performance considerably. Adequate disclosure of information has a significant impact on corporate performance by increasing pressure on managers and helpful to trim down the agency problem. Nevertheless, there is no significant relationship between corporate performance and introduction of 'executive officer system' or 'outside director system'. Companies with high level of foreign shareholding and high dependence on capital markets are dynamically reforming their governance structures while companies with a high ratio of stable stockholders and more dependence on borrowing are inactive in reforming.

description: A. Executive SummaryThe pharmaceutical industry is one of
industries in the modern world. Despite the contentiousness of some predatory pricing behaviors, the ultimate output of life-saving medications is a crucial component of modern medicine and healthcare. However, drug discovery has reached a peak in which companies in this industry must now find ways to further innovate and modernize. The traditional days of serendipitous discovery of simple compounds have now been replaced by more complex, expensive, and extensive biotherapeutic drugs that are often made in live vessels and are biologic in nature.The extent of the efficacy of these biologic drugs are impactful, with the development of Hepatitis-C treatments that have effectively cured the disease, however, the extent of finances invested in developing these drugs are substantial. In order for pharmaceutical companies to remain competitive and profitable, companies must utilize data analytics across multiple avenues of the value chain in order maximize operations and increase cost savings. With a projected 6.4% increase in compounded annual growth rate (CAGR) by 2024 (Evaluate Pharma, 2018) and a 5.8% increase in global market value (The Business Research Company, 2018), the industry must be prepared to innovate and modernize in order to remain relevant.Major players including: Johnson & Johnson, Pfizer, Merck, and Amgen have begun utilizing data analytic systems and artificial intelligence to maximize drug discovery in addition to optimizing operational efficiency. With a potential increase of 75% peak EBITDA impact within a 10-year time frame, many pharmaceutical companies are becoming aware of the potential benefits of utilizing data analytics within all facets of the pharmaceutical value chain (Darino et al., 2018).

description: The Upper Triassic Langjiexue Group, which lies immediately south of the Yarlung-Tsangpo Suture Zone in the Shannan area of southeastern Tibet, represents an important part of the Tethyan Himalayan Sequence (THS). Its provenance and palaeogeography have been the subject of debate. We present new data on petrographic composition, whole-rock geochemistry, and detrital zircon U–Pb geochronology to constrain the provenance of the Langjiexue Group. The dominance of quartz grains and felsic volcanic lithic fragments suggests that the sandstones are litho-quartzose. The trace element geochemical signatures (V–Ni–Th*10, Co/Th–La/Sc, Eu/Eu*–Th/Sc) suggest derivation from felsic igneous sources. The detrital zircon age spectra display three major peaks: a Meso-to-Neoproterozoic peak (1200–900 Ma, 7–18%), a Neoproterozoic-to-Late Cambrian peak (750–500 Ma, 32–65%), and a Late Carboniferous-to-Late Triassic peak (300–200 Ma, 11–33%). The maximum depositional age of early Carnian (236–235 Ma) is obtained by calculating weighted average ages of the youngest zircons (≤250 Ma). The youngest age cluster (300–200 Ma) is incompatible with sources from neighbouring terranes, including the South Qiangtang terrane, Lhasa terrane, THS, and Higher Himalayan Crystalline. Correlations of the Permian–Triassic zircons with those of time-equivalent strata in northwest Australia, west Burma, and the Banda Arc unveil a potential connection to the Tasmanides along the convergent margin of eastern Australia. The New England Orogen (300–230 Ma) could have supplied the Langjiexue Group with magmatic materials via continent-scale drainage systems or a submarine fan complex. This scenario provides a new perspective into the transport of detritus from distal orogens to sedimentary basins thousands of kilometres away.
Development and initial validation of an assessment of visual ability for children with cerebral palsy

description: BACKGROUND Children with cerebral palsy have a primary motor disorder that may be accompanied by disturbances of sensation or perception that impact their ability to use vision. Many other factors may also influence how a child ‘uses their vision’, yet our understanding of how to optimise outcomes rarely includes a focus on visual abilities. For some children with cerebral palsy, visual ability may be a strength. To maximise a child’s ability to use vision we first need a method to quantify visual ability. This thesis describes the conceptualisation, development, and initial validation of a scale to describe ‘how vision is used’ by children with cerebral palsy. 

METHODS Using a multi-phase mixed methods instrument project design, the first step was a systematic review to identify and appraise existing measures. This was followed by a study to map items from existing measures to the International Classification of Functioning, Disability and Health (ICF) framework using standard linking methodology. After confirming the need for a new measurement tool, the second phase of this research involved an international online survey of key stakeholders; the construction of items and a rating scale; and pre-testing with cognitive interviews. The third phase explored the psychometric properties of the tool in initial field testing.
 
RESULTS The systematic review confirmed a gap in assessment practices for describing ‘how vision is used’. The mapping exercise led to the conceptualisation of visual ability as a measurable construct at the Activity level of the ICF, and observable visual behaviours were identified to describe how vision is used. Findings from the stakeholder survey contributed to evidence of the relevance and comprehensiveness of content, whilst also defining what is not the focus of the measure: child factors (e.g. eye functions), environmental factors (e.g. type of visual information), or performance and participation in vision-related activities (e.g. play). The primary outcome of this research, the Measure of Early Vision Use (MEVU), is a 14-item parent-report questionnaire describing a child’s ability to use vision. Each item is an observable visual behaviour, scored on a 4-point ordinal scale. Psychometric data from field testing (n=100) supports MEVU as a unidimensional scale with good internal consistency, sufficient construct validity, and feasibility as a parent-completed online assessment.

CONCLUSION MEVU is a new instrument to describe the use of basic visual abilities that has potential to support early intervention planning for children with (or at high risk of) cerebral palsy.

description: Uncertainty of decisions in safety-critical engineering applications can be estimated on the basis of the Bayesian Markov Chain Monte Carlo (MCMC) technique of averaging over decision models. The use of decision tree (DT) models assists experts to interpret causal relations and find factors of the uncertainty. Bayesian averaging also allows experts to estimate the uncertainty accurately when a priori information on the favored structure of DTs is available. Then an expert can select a single DT model, typically the Maximum a Posteriori model, for interpretation purposes. Unfortunately, a priori information on favored structure of DTs is not always available. For this reason, we suggest a new prior on DTs for the Bayesian MCMC technique. We also suggest a new procedure of selecting a single DT and describe an application scenario. In our experiments on the Short-Term Conflict Alert data our technique outperforms the existing Bayesian techniques in predictive accuracy of the selected single DTs.

description: We discuss the merger rate, close galaxy environment, and clustering on scales up to a Mpc of the SWIFT BAT hard X-ray sample of nearby (z<0.05), moderate-luminosity active galactic nuclei (AGN). We find a higher incidence of galaxies with signs of disruption compared to a matched control sample (18% versus 1%) and of close pairs within 30 kpc (24% versus 1%). We also find a larger fraction with companions compared to normal galaxies and optical emission line selected AGN at scales up to 250 kpc. We hypothesize that these merging AGN may not be identified using optical emission line diagnostics because of optical extinction and dilution by star formation. In support of this hypothesis, in merging systems we find a higher hard X-ray to [OIII] flux ratio, as well as emission line diagnostics characteristic of composite or star-forming galaxies, and a larger IRAS 60 um to stellar mass ratio.

description: Tra il 1965 e il 1981, gli attori Leo de Berardinis e Perla Peragallo scelsero di vivere e fare teatro in una vecchia masseria di Marigliano, piccolo paese alle porte di Napoli. Qui fondarono il «teatro dell’ignoranza» con cui i due artisti intendevano allontanarsi dalle formule trite del teatro classico italiano e dell’avanguardia fine a sé stessa, al fine di individuare una via artistica che ricercasse l’autenticità del faticoso lavoro teatrale, non il bello. Lavorando con attori non professionisti, Leo e Perla costruirono una poetica basata sulla perifericità geografica e sulla marginalità sociale, fondendo riferimenti culturali e teatrali apparentemente tra loro inconciliabili: l’avanspettacolo e la poesia, la sceneggiata napoletana e William Shakespeare. Nel saggio, attraverso l’analisi di tre spettacoli prodotti a Marigliano tra il 1972 e il 1974, si individuano i successi e i limiti del «teatro dell’ignoranza» per raccontare uno spaccato generazionale, politico ed estetico del teatro italiano d’avanguardia.
description: From 1965 to 1981, the actors Leo de Berardinis and Perla Peragallo lived and worked in an old farm in Marigliano, a small town near Naples. Here, they founded the so-called «theatre of ignorance». The two artists wished to abandon the repetitive canons of traditional theatre as much as the self-reflexive attitude of avantgarde movements, and to create a new artistic path interested in analyzing the depth and pain of stagecraft, not its beauty. Leo and Perla worked with non-professional actors, envisioned a poetic based on geographic peripherality and social marginality, and mixed cultural references that seemed irreconcilable: variety show and poetry, Neapolitan sceneggiata and William Shakespeare. In the essay, I briefly analyze three shows produced in Marigliano from 1972 to 1974, and I point out the pros and cons of «theatre of ignorance» to discuss its generational, political and aesthetic contributions to a central period of Italian experimental theatre.
Genetic population structure and adaptation to climate across the range of eastern white pine (Pinus strobus L.) and western white pine (Pinus monticola Douglas ex D. Don).

description: Under rapid global warming, it is critical to better understand the capacity of forest trees to adapt to a changing climate. Western white pine (Pinus monticola Douglas ex D. Don) and eastern white pine (P. strobus L.) are species at higher risk to climate change, as both have fragmented ranges and have suffered declines due to harvesting, fire suppression, and the white pine blister rust. We identified and compared patterns of genetic diversity and adaptation to climate in both species using a set of 267 orthologous genes. These genes included candidates for growth, bud phenology, and resistance to biotic and abiotic stresses. Genotyping resulted in 158 and 153 successful SNPs for P. monticola and P. strobus, respectively. Each set of SNPs was genotyped on range-wide samples of 362 P. monticola individuals (61 populations) and 840 P. strobus individuals (133 populations). Analyses were conducted separately in each species. STRUCTURE analyses identified two genetic clusters in each species, corresponding to north-south genetic discontinuities, as well as weak hierarchical sub-structure within each of those groups. We found evidence of local adaptation in both species. FST outlier analyses revealed that ∼7 percent and ∼10 percent of SNPs were under selection in P. monticola and P. strobus, respectively. Environmental association methods identified that ∼38 percent of P. monticola SNPs and ∼47 percent of P. strobus SNPs were correlated with climate. Strong candidate genes for future adaptation studies were identified: 7 genes in each species were detected by at least 2 methods and 22 candidate genes were common to both species. These genes were involved in growth, bud phenology, and response to abiotic and biotic stress. The implications of these findings for the conservation of white pine populations under climate change are discussed.

description: Quantum ground-state problems are computationally hard problems; for general many-body Hamiltonians, there is no classical or quantum algorithm known to be able to solve them efficiently. Nevertheless, if a trial wavefunction approximating the ground state is available, as often happens for many problems in physics and chemistry, a quantum computer could employ this trial wavefunction to project the ground state by means of the phase estimation algorithm (PEA). We performed an experimental realization of this idea by implementing a variational-wavefunction approach to solve the ground-state problem of the Heisenberg spin model with an NMR quantum simulator. Our iterative phase estimation procedure yields a high accuracy for the eigenenergies (to the 10^-5 decimal digit). The ground-state fidelity was distilled to be more than 80%, and the singlet-to-triplet switching near the critical field is reliably captured. This result shows that quantum simulators can better leverage classical trial wavefunctions than classical computers.

description: We present angle-resolved photoemission spectroscopy (ARPES) studies of the cuprate high-temperature superconductors which elucidate the relation between superconductivity and the pseudogap and highlight low-energy quasiparticle dynamics in the superconducting state. Our experiments suggest that the pseudogap and superconducting gap represent distinct states, which coexist below T$_c$. Studies on Bi-2212 demonstrate that the near-nodal and near-antinodal regions behave differently as a function of temperature and doping, implying that different orders dominate in different momentum-space regions. However, the ubiquity of sharp quasiparticles all around the Fermi surface in Bi-2212 indicates that superconductivity extends into the momentum-space region dominated by the pseudogap, revealing subtlety in this dichotomy. In Bi-2201, the temperature dependence of antinodal spectra reveals particle-hole asymmetry and anomalous spectral broadening, which may constrain the explanation for the pseudogap. Recognizing that electron-boson coupling is an important aspect of cuprate physics, we close with a discussion of the multiple 'kinks' in the nodal dispersion. Understanding these may be important to establishing which excitations are important to superconductivity.

description: We investigate the evolution of young star clusters using N-body simulations. We confirm that subvirial and fractal-structured clusters will dynamically mass segregate on a short timescale (within 0.5 Myr). We adopt a modified minimum-spanning-tree (MST) method to measure the degree of mass segregation, demonstrating that the stars escaping from a cluster's potential are important for the temporal dependence of mass segregation in the cluster. The form of the initial velocity distribution will also affect the degree of mass segregation. If it depends on radius, the outer parts of the cluster would expand without undergoing collapse. In velocity space, we find 'inverse mass segregation,' which indicates that massive stars have higher velocity dispersions than their lower-mass counterparts.

Measurements of carbon dioxide fluxes and concentrations at multiple scales in Vancouver, Canada

Publisher: name: University of British Columbia

description: Global carbon dioxide (CO₂) atmospheric mixing ratios and near-surface air temperatures are projected to rise for the foreseeable future. Given that human populations and activity are concentrated in urban areas, knowledge and quantification of CO₂ emissions and uptake processes is important for urban sustainable development applications and emission reduction efforts. Atmospheric measurements of CO₂ in Vancouver, BC were conducted from 2008-2012 to improve spatial resolution of emissions monitoring techniques and advance understanding of urban CO₂ atmospheric transport processes. Three datasets representative of three urban climate scales were collected. At the neighborhood-scale, four years (2008-2012) of eddy covariance (EC) net CO₂ emissions measurements were analyzed with spatial turbulent flux source area models. This allowed high-resolution spatial attribution of the net flux to individual source/sink processes and reduced spatial bias in EC-measured annual net emissions totals. Empirical models developed from three years of hourly EC data (2008-2011) were used to predict net emissions for a fourth year (2011-2012) with errors of 6.7% compared to direct EC measurements on daily timescales. At the micro-scale, high-resolution spatial variations in CO₂ mixing ratios measured at 2 m height from a mobile, vehicle-mounted platform were observed. Nighttime CO₂ mixing ratio patterns were correlated with potential air temperature, suggesting micro-scale advective processes are an important determinant of UCL pollutant transport. Micro-scale observations are linked to local-scale EC flux measurements through consideration of the EC storage flux term (FS). Uncertainties in hourly FS calculated from a single observation height at EC level are caused by flushing of CO₂ from the UCL shortly after sunrise and from CO₂ buildup in the UCL shortly after sunset. CO₂ mixing ratios representative of the city-scale were measured in the urban boundary layer (UBL) using a tethered-balloon system. The net CO₂ flux representative of the city-scale is inferred from hourly changes in UBL CO₂ together with UBL height measurements from a ceilometer. The surface flux calculated using this method is comparable to local-scale urban EC measurements during the same period, however there is uncertainty in the horizontal advective flux resulting from sensitivity to parameterization of CO₂ mixing ratios in upwind, non-urban areas.

description: In this paper we construct four Kerr-like spacetimes starting from the loop black hole Schwarzschild solutions (LBH) and applying the Newman-Janis transformation. In previous papers the Schwarzschild LBH was obtained replacing the Ashtekar connection with holonomies on a particular graph in a minisuperspace approximation which describes the black hole interior. Starting from this solution, we use a Newman-Janis transformation and we specialize to two different and natural complexifications inspired from the complexifications of the Schwarzschild and Reissner-Nordstrom metrics. We show explicitly that the space-times obtained in this way are singularity free and thus there are no naked singularities. We show that the transformation move, if any, the causality violating regions of the Kerr metric far from r=0. We study the space-time structure with particular attention to the horizons shape. We conclude the paper with a discussion on a regular Reissner-Nordstrom black hole derived from the Schwarzschild LBH and then applying again the Newmann-Janis transformation.

Operating in the general and medical and surgical hospital industry, this company has continued to expand its current portfolio through acquisitions, joint ventures, and partnerships. Based on projections, EPS is expected to reach $11 per share by 2020 and potentially reach revenue of almost $55 billion also by 2020Although no other hospital company is comparable to size of HCA’s dominance with a 4.5% market share, HCA has experienced net income losses due to natural disasters resulting from hurricanes. Additionally, liabilities of HCA far exceed its assets and continued increases in bad debt/doubtful accounts continue to plague the company from improve profit margins. Despite operating in the hospital industry and being at the mercy of third-party insurers and delayed government reimbursement, HCA has continued to thrive with a strong ROIC and above average EBITDA margins.Utilization of beta, standard deviation, and coefficient of variation indicates that HCA is a strong company with sustain growth in market asset returns and is a low risk investment in addition to and great potential returns. However, weighted average cost of capital (WACC) is above industry average indicating the company may be limiting profit margins as a result of high cost of capital although returns on investment offset these higher costs. Overall, HCA is financially performing better than other companies within the industry and is projected to continually outperform competitors.

Contradictions and exclusions : an ethnographic study of African im/migrants' right to health in Italy
Creators: name: Oliverio-Lauderdale, Daniela
Publisher: name: University of British Columbia
Year: 2014

description: This thesis examines the complex and “messy” nature of the right to health and its intersections with race, gender, and migration in the Italian context. The laws in Italy purportedly outline a framework that includes “illegal” im/migrants in the healthcare system. The diverse ways in which the “right to health” have been understood theoretically are based on a commitment to universal and legal rights or the right to health from a moral and humanitarian perspective. Drawing on participant observation in medical clinics, and semi-structured formal and informal interviews with medical staff, practitioners and patients in two cities of Italy, this thesis provides insights into “the right to health” in theory and in practice. Two key concepts in the study of the right to health are moral economies and biolegitimacy. On the basis of my research I argue that currently, the moral economy of health in Italy regarding “illegal” im/migrants is one of reluctant compassion. While im/migrants’ social legitimacy stems from their biological state, or biolegitimacy, within the setting of the clinics it does not necessarily extend further. In Italy, “illegal” im/migrants enjoy legitimacy via their biolegitimacy, but they are yet to be fully accepted into the social and moral community. While “illegal” im/migrants are recognized as having a right to health they are simultaneously excluded politically, economically, and discursively from the social community. Even in the “humanitarian” version of healthcare in Italy which provides a legal framework where, in principal, everyone can access healthcare, there is still a lack of comprehensive treatment (cura totale). Ultimately, this thesis demonstrates the ways in which the right to health in Italy is complex, messy and often contradictory with respect to other aspects of social life even in a context where there is a legal framework outlining a provision of healthcare for all. Additional research is necessary to understand how the right to health is interpreted in other regions of Italy and particularly in detention centers, such as Lampedusa, which have received a lot of media attention recently for their treatment of African detainees and im/migrants.

description: Company IntroductionPillPack was originally founded in 2013 by TJ Parker, a second- generation pharmacist based out of the New England area (PillPack Press). The original concept of the company was to simplify the overabundance of pill bottles for patients in the United States. While completing his Doctor of Pharmacy (PharmD), TJ Parker met Elliot Cohen and together they developed the pharmacy system and technology that would incorporate medication reconciliation into a modern pre-rolled package customized for each patient. TJ leveraged his family’s experience in pharmacy practice to maximize mail order delivery in the United States and helped develop PharmacyOS, a proprietary software platform exclusive to PillPack that accurately manages patient medications, refills, and shipment integration (PillPack Press).

description: Holmberg IX X-1 is a well-known ultraluminous X-ray source with an X-ray luminosity of ~1e40 erg/s. The source has been monitored by the X-ray Telescope of Swift regularly. Since 2009 April, the source has been in an extended low luminosity state. We utilize the co-added spectra taken at different luminosity states to study the spectral behavior of the source. Simple power-law and multi-color disk blackbody models can be ruled out. The best overall fits, however, are provided by a dual thermal model with a cool blackbody and a warm disk blackbody. This suggests that Holmberg IX X-1 may be a 10 solar-mass black hole accreting at 7 times above the Eddington limit or a 100 solar-mass maximally rotating black hole accreting at the Eddington limit, and we are observing both the inner regions of the accretion disk and outflows from the compact object.

Giant radiation heat transfer through the micron gaps

description: Near-field heat transfer between two closely spaced radiating media can exceed in orders radiation through the interface of a single black body. This effect is caused by exponentially decaying (evanescent) waves which form the photon tunnel between two transparent boundaries. However, in the mid-infrared range it holds when the gap between two media is as small as few tens of nanometers. We propose a new paradigm of the radiation heat transfer which makes possible the strong photon tunneling for micron thick gaps. For it the air gap between two media should be modified, so that evanescent waves are transformed inside it into propagating ones. This modification is achievable using a metamaterial so that the direct thermal conductance through the metamaterial is practically absent and the photovoltaic conversion of the transferred heat is not altered by the metamaterial.

description: L’attività artistica di Antonio Freiles, nato e vissuto in Sicilia, si inserisce in un fitto contesto di relazioni nazionali e internazionali. Espone i suoi lavori nelle maggiori biennali, musei e gallerie del mondo, tra cui la White Chapel Gallery e la Tate Gallery a Londra e il Centre Pompidou a Parigi, indagando il nesso tra architettura e colore, segno e spazio, confini e libertà espressiva. Le direttrici della sua opera sono tre: la passione per la cellulosa, lavorata a mano nelle Chartae, la collezione di libri d’arte ed edizioni rare ed infine l’editoria attraverso la rivista bilingue «Carte d’Arte Internazionale».
description: Born in Sicily, Antonio Freiles has exhibited his artworks in major European Biennials and in the most important private and public museums in the world, including the Tate Gallery, the White Chapel in London and the Center Georges Pompidou in Paris. His paintings explore the connection between space and sign, architecture and light, borders and expressive freedom. Three activities can be recognized through the course of Freiles’ career: the series of paintings executed on handmade paper made of cellulose, called Chartae; a large art book collection and the «Carte d’Arte Internazionale» magazine of wich he was the editor.
Accretion of dust by chondrules in a MHD-turbulent solar nebula

description: (Abridged) Numerical magnetohydrodynamic (MHD) simulations of a turbulent solar nebula are used to study the growth of dust mantles swept up by chondrules. A small neighborhood of the solar nebula is represented by an orbiting patch of gas at a radius of 3 AU, and includes vertical stratification of the gas density. The differential rotation of the nebular gas is replaced by a shear flow. Turbulence is driven by destabilization of the flow as a result of the magnetorotational instability (MRI), whereby magnetic field lines anchored to the gas are continuously stretched by the shearing motion. A passive contaminant mimics small dust grains that are aerodynamically well coupled to the gas, and chondrules are modeled by Lagrangian particles that interact with the gas through drag. Whenever a chondrule enters a region permeated by dust, its radius grows at a rate that depends on the local dust density and the relative velocity between itself and the dust. The local dust abundance decreases accordingly. Different chondrule volume densities lead to varying depletion and rimmed-chondrule size growth times. Most of the dust sweep-up occurs within 1 gas scale height of the nebula midplane. Chondrules can reach their asymptotic radius in 10 to 800 years. The vertical variation of nebula turbulent intensity results in a moderate dependence of mean rimmed-chondrule size with nebula height. The technique used here could be combined with Monte Carlo (MC) methods that include the physics of dust compaction, in a self-consistent MHD-MC model of dust rim growth around chondrules in the solar nebula.

description: We investigate scatterer induced mode splitting in a composite microtoroidal resonator (Q ~ 10^6) fabricated by coating a silica microtoroid (Q ~ 10^7) with a thin poly(dimethylsiloxane) layer. We show that the two split modes in both coated and uncoated silica microtoroids respond in the same way to the changes in the environmental temperature. This provides a self-referencing scheme which is robust to temperature perturbations. Together with the versatile functionalities of polymer materials, mode splitting in polymer and polymer coated microresonators offers an attractive sensing platform that is robust to thermal noise.
