description: Extruded polystyrene rigid foams have attracted a great attention as a superior load-bearing thermal insulation material since their implementation in building construction. One of the most common application areas of this type of thermal insulation material is under raft foundations, where the foam normally undergoes high levels of compression loads. The purpose of this research is to determine how to simulate and optimize the structural response of extruded polystyrene under compression stresses. The optimization has been achieved through investigating the relation between the foam microstructure and the global mechanical properties. The foam was first examined using X-ray tomography imaging technique to acquire some morphological information about the microstructure. The obtained morphological data of extruded polystyrene boards were then utilized to develop microstructure-based finite element models based on the so-called idealized realistic Kelvin cell. The finite element simulation was accomplished with the help of the nanoindentation technology to explore the mechanical properties of the cell wall material. The finite element models were validated by comparisons between the simulated and the experimental results. It has been found that the mechanical properties of the foam in different loading directions can be adequately simulated using the approach of the idealized realistic Kelvin cell. With the help of these models, a parameter study was carried out. This study included the effect of cell size and cell anisotropy on the mechanical response of extruded polystyrene boards under compression stresses. Charts relating between the foam microstructure characteristics and the compression behavior were generated based on the parametric study. © The Author(s) 2013.

The Young Open Clusters King 12, NGC 7788, and NGC 7790: Pre-Main Sequence Stars and Extended Stellar Halos

description: The stellar contents of the open clusters King 12, NGC 7788, and NGC 7790 are investigated using MegaCam images. Comparisons with isochrones yield an age < 20 Myr for King 12, 20--40 Myr for NGC 7788, and 60 -- 80 Myr for NGC 7790 based on the properties of stars near the main sequence turn-off (MSTO) in each cluster. The reddening of NGC 7788 is much larger than previously estimated. The luminosity functions (LFs) of King 12 and NGC 7788 show breaks that are attributed to the onset of pre-main sequence (PMS) objects, and comparisons with models of PMS evolution yield ages that are consistent with those measured from stars near the MSTO. In contrast, the r' LF of main sequence stars in NGC 7790 is matched to r' = 20 by a model that is based on the solar neighborhood mass function. The structural properties of all three clusters are investigated by examining the two-point angular correlation function of blue main sequence stars. King 12 and NGC 7788 are each surrounded by a stellar halo that extends out to 5 arcmin (~ 3.4 parsecs) radius. It is suggested that these halos form in response to large-scale mass ejection early in the evolution of the clusters, as predicted by models. In contrast, blue main sequence stars in NGC 7790 are traced out to a radius of ~ 7.5 arcmin, with no evidence of a halo. It is suggested that all three clusters may have originated in the same star-forming complex, but not in the same giant molecular cloud.

description: The Fermi-LAT telescope has unexpectedly discovered GeV gamma-ray emission from the symbiotic Nova V407 Cygni. We investigate the radiation processes due to electrons and hadrons accelerated during the explosion of this Nova. We consider a scenario in which GeV gamma-ray emission observed by Fermi is produced by the electrons with energies of a few tens of GeV in the inverse Compton scattering of stellar radiation. On the other hand, the hadrons are expected to reach larger energies, due to the lack of radiation losses during acceleration process, producing TeV gamma-rays and neutrinos. We predict the fluxes of very high energy gamma-rays and neutrinos from Novae of the V407 type for two models of hadron acceleration and discuss their possible detectability by the present and future telescopes (e.g. IceCube, CTA)

description: The main purpose of this paper is to present a conceptual approach to understanding the extension of the Prym map from the space of admissible double covers of stable curves to different toroidal compactifications of the moduli space of principally polarized abelian varieties. By separating the combinatorial problems from the geometric aspects we can reduce this to the computation of certain monodromy cones. In this way we not only shed new light on the extension results of Alexeev, Birkenhake, Hulek, and Vologodsky for the second Voronoi toroidal compactification, but we also apply this to other toroidal compactifications, in particular the perfect cone compactification, for which we obtain a combinatorial characterization of the indeterminacy locus, as well as a geometric description up to codimension six, and an explicit toroidal resolution of the Prym map up to codimension four. © 2017 European Mathematical Society.

description: We report on a kerfless exfoliation approach to further reduce the costs of crystalline silicon photovoltaics making use of evaporated Al as a double functional layer. The Al serves as the stress inducing element to drive the exfoliation process and can be maintained as a rear contacting layer in the solar cell after exfoliation. The 50-70 μm thick exfoliated Si layers show effective minority carrier lifetimes around 180 μs with diffusion lengths of 10 times the layer thickness. We analyze the thermo-mechanical properties of the Al layer by x-ray diffraction analysis and investigate its influence on the exfoliation process. We evaluate the approach for the implementation into solar cell production by determining processing limits and estimating cost advantages of a possible solar cell design route. The Al-Si bilayers are mechanically stable under processing conditions and exhibit a moderate cost savings potential of 3-36% compared to other c-Si cell concepts. © Materials Research Society 2015.

description: This article presents a new multiscale modeling approach proposed to predict the impact response of a biomedical niobium-zirconium alloy by incorporating both geometric and microstructural aspects. Specifically, the roles of both anisotropy and geometry-based distribution of stresses and strains upon loading were successfully taken into account by incorporating a proper multiaxial material flow rule obtained from crystal plasticity simulations into the finite element (FE) analysis. The simulation results demonstrate that the current approach, which defines a hardening rule based on the location-dependent equivalent stresses and strains, yields more reliable results as compared with the classical FE approach, where the hardening rule is based on the experimental uniaxial deformation response of the material. This emphasizes the need for proper coupling of crystal plasticity and FE analysis for the sake of reliable predictions, and the approach presented herein constitutes an efficient guideline for the design process of dental and orthopedic implants that are subject to impact loading in service.

Orbital evolution of a planet on an inclined orbit interacting with a disc

description: We study the dynamics of a planet on an orbit inclined with respect to a disc. If the initial inclination of the orbit is larger than some critical value, the gravitational force exerted by the disc on the planet leads to a Kozai cycle in which the eccentricity of the orbit is pumped up to large values and oscillates with time in antiphase with the inclination. On the other hand, both the inclination and the eccentricity are damped by the frictional force that the planet is subject to when it crosses the disc. We show that, by maintaining either the inclination or the eccentricity at large values, the Kozai effect provides a way of delaying alignment with the disc and circularization of the orbit. We find the critical value to be characteristically as small as about 20 degrees. Typically, Neptune or lower mass planets would remain on inclined and eccentric orbits over the disc lifetime, whereas orbits of Jupiter or higher mass planets would align and circularize. This could play a significant role in planet formation scenarios.

Of 'true professionals' and 'ethical hero warriors': A gender-discourse analysis of private military and security companies

description: Private military and security companies (PMSCs) have gained increasingly in importance over the course of the past two decades. Yet, given the intransparency of the industry and the heterogeneity of the companies that comprise it, we thus far know little about the actors involved. In this article, we offer preliminary insights into the self-representation of PMSCs, based on a gender-discourse analysis of the homepages of select companies and their main professional associations. We argue that survival in an increasingly competitive industry not only hinges on size, market share or effectiveness, but is also inherently gendered. PMSCs and their associations draw on the one hand on civilized and accepted forms of masculinity and femininity, presenting themselves as 'highly skilled professional' military strategists and ordinary businesses akin to banks or insurance companies. At the same time, however, PMSCs also engage in strategies of (hyper)masculinization and pathologization to set themselves apart from mercenaries, their private competitors and state security forces. In this respect, companies appear to view themselves as 'ethical hero warriors'. Whether intended or not, their strategies have political consequences. Within the security industry, they contribute to the creation and maintenance of a norm regarding what constitutes a legitimate PMSC, to which more or less all companies strive to adhere. Vis-à-vis other security actors, these strategies seek to establish PMSCs as being superior because, unlike these actors, such companies are super-masculine and able to live up to the growing and sometimes contradictory demands of changing security contexts. © The Author(s) 2012.

description: We investigate interaction effects in transport phenomena in bilayer graphene (BLG). For the minimal conductivity in pristine BLG, we find that the conductivity assumes a constant value in the limit $T\to 0$, with the first correction being $\propto \sqrt{T}$. This has to be contrasted from the standard $1/T^2$ in Fermi liquids (neglecting additional logarithms and above all disorder). We furthermore study the Coulomb drag resistivity between two BLGs in the whole range from deep within the Fermi liquid regime all the way to the charge neutrality (CN) point. We find that in the Fermi liquid regime drag behaves very similarly to drag in a standard two-dimensional electron gas. In contrast to monolayer graphene, we find no saturation of drag as a function of the distance $d$ for realistic parameters. In the vicinity of CN, we find an interesting interplay between interaction effects and disorder, like in the case of monolayer graphene. Here the drag resistivity strongly depends upon the ratio of the corresponding scattering times.

description: On August 9, 2011, there was an X6.9 flare event occurred near the west limb of solar disk. From the observation obtained by the spectrometer of the Chinese Solar Broadband Radio Spectrometer in Huairou (SBRS/Huairou) around the flare, we find that this powerful flare has only a short-duration microwave burst of about only 5 minutes, and during the short-duration microwave burst, there are several kinds of fine structures on the spectrogram. These fine structures include very short-period pulsations, millisecond spike bursts, and type III bursts. The most interesting is that almost all of the pulses of very short-period pulsation (VSP) are structured by clusters of millisecond timescales of spike bursts or type III bursts. And there exists three different kinds of frequency drift rates in the VSP: the frequency drift rates with absolute value of about 55 - 130 MHz s^{-1} in the pulse groups, the frequency drift rates with absolute value of about 2.91 - 16.9 GHz s^{-1} on each individual pulse, and the frequency drift rates with absolute value of about 15 - 25 GHz s$^{-1}$) at each individual spike burst or type III burst.

description: We briefly review the recently constructed two orbital microscopic model for iron-based superconductors based on $S_4$ symmetry (PRX 2 021009(2012)). With this faithful representation of the kinematics of the tri-layer FeAs or FeSe structure, the model provides answers and physical pictures to fundamental questions related to the robustness of superconductivity and pairing symmetry, unifies different families of iron-based superconductors, casts new insight into the connections to the other high $T_c$ superconductors, cuprates, and reveals why an s-wave pairing can be stabilized by repulsive interactions. Further progresses include that the model provides a clean understanding of band reconstruction observed in magnetically ordered states, which is a strong support to the kinematics of the $S_4$ model, and captures the essential low energy physics of iron-based superconductors based on numerical results from unbiased quantum Monte Carlo simulation.

Time Scales in Tidal Disruption Events

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We explore the temporal structure of tidal disruption events pointing out the corresponding transitions in the lightcurves of the thermal accretion disk and of the jet emerging from such events. The hydrodynamic time scale of the disrupted star is the minimal time scale of building up the accretion disk and the jet and it sets a limit on the rise time. This suggest that Swift J1644+57, that shows several flares with a rise time as short as a few hundred seconds could not have arisen from a tidal disruption of a main sequence star whose hydrodynamic time is a few hours. The disrupted object must have been a white dwarf. A second important time scale is the Eddington time in which the accretion rate changes form super to sub Eddington. It is possible that such a transition was observed in the light curve of Swift J2058+05. If correct this provides intersting constraints on the parameters of the system.

description: Company-level pacts between the management and the works council are often preferred in comparison to agreements between employers’ association and unions because the former negotiating partners are better informed about the economic situation of a company and have fewer goal conflicts than the latter. Moreover, these company-level pacts might reduce the ‘hold-up’ problems which arise once specialized investment is made. Therefore, this article investigates whether such agreements affect firm-level investment. Based on the IAB Establishment Panel Survey 2001–2010 the study indicates that the adoption of a company-level pact leads to a higher investment rate than in other firms driven by reinvestment. However, the Great Recession has damped this positive influence. From the econometric analysis the article does not detect any increase in investment during the negotiation phase. After the expiration of a company-level pact, lower reinvestment and a small increase in net investment take place. © 2013, © The Author(s) 2013.

Quarkonia and heavy-flavour production in CMS
Creators: name: Dahms, Torsten
Publisher: name: arXiv
Year: 2012
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The Compact Muon Solenoid (CMS) has measured numerous quarkonium states via their decays into muon pairs in pp and PbPb collisions at sqrt(s_NN) = 2.76 TeV. Quarkonia are especially relevant for studying the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. Non-prompt J/psi from b-hadron decays show a strong suppression in the transverse momentum range (6.5 < p_T < 30 GeV/c) when compared to the yield in pp collisions scaled by the number of inelastic nucleon-nucleon collisions. This suppression is related to the in-medium b-quark energy loss. In the same kinematic region, for prompt J/psi, a strong, centrality-dependent suppression is observed in PbPb collisions. Such strong suppression at high p_T has previously not been observed at RHIC. At midrapidity (|y| < 1.6) and the same p_T region, inclusive psi(2S) are even stronger suppressed than J/psi, whereas psi(2S) at forward rapidity (1.6 < |y| < 2.4) and lower p_T (3 < p_T < 30 GeV/c) appear to be less suppressed than J/psi, however, with large uncertainties that prevent a conclusion. Furthermore, low-p_T Y(2S) and Y(3S) mesons are strongly suppressed in PbPb collisions. The suppression of the Y(1S) state is smaller than the suppression of the excited states and consistent with the suppression of the feed-down contribution only.

description: INTRODUCTION This case report traces the diagnostic and therapeutic process of the Immuno-Transfusion Service in a case of fetal anaemia characterized by various inconsistencies between clinical and laboratory data. The paper describes an alternative technique implemented with the aim of resolving incompatibilities between positive IAT and negative DAT. In addition, the algorithm necessary to reach a diagnosis in a transfusion medicine laboratory is traced, namely, the performance of first- and second-level immuno-haematological tests, the evaluation of fetal clinical signs, and the preparation of blood components necessary for intrauterine transfusion. CASE PRESENTATION The case involves a pregnant woman who comes to the Immuno-Transfusion Service following a positive Indirect Antiglobulin Test and fetal anaemia. The main questions relate not only the presence of immunization in the woman, which should have been avoided by immunoprophylaxis (being group 0 Rh negative), but also the stability of the antibody titer (or level) throughout the pregnancy, fetal recovery after TIU, and the presence of a negative Direct Antiglobulin Test. CONCLUSIONS Questions that were completely resolved at caesarean section with the discovery of a giant chorioangioma that, by sequestering fetal red blood cells, caused anaemia and the confirmation of a rare blood phenotype of the father that caused the woman's immunization.

I will argue that both views are unsatisfactory. The subsequent part of the article will introduce an alternative role for ontological projects in the philosophy of the social sciences that fares better in this respect by paying attention to the ontological assumptions of actual social scientific theories, models, and related explanatory practices. I will illustrate and support this alternative through discussion of three concrete cases. © The Author(s) 2016.

description: INTRODUZIONE Questo case report ripercorre l’iter diagnostico e terapeutico del Servizio Immuno-Trasfusionale in un caso di anemia fetale caratterizzato da varie incongruenze tra i dati clinici e di laboratorio. Nell’articolo viene descritta anche una tecnica alternativa attuata con l’obiettivo di risolvere le incompatibilità tra Test di Coombs Indiretto positivo e Test di Coombs Diretto negativo. Si ripercorre, inoltre, l’algoritmo necessario al raggiungimento di una diagnosi in un laboratorio di Medicina Trasfusionale, ovvero l’esecuzione degli esami immunoematologici di primo e secondo livello, la valutazione dei segni clinici fetali e la preparazione degli emocomponenti necessari alla trasfusione intrauterina. PRESENTAZIONE DEL CASO Il caso riguarda una donna gravida che giunge nel servizio Immuno-Trasfusionale per il riscontro di un Test di Coombs Indiretto positivo e di un’anemia fetale. I principali quesiti riguardano non solo la presenza di immunizzazione nella donna, che si sarebbe dovuta evitare con l’immunoprofilassi (essendo di gruppo 0 Rh negativo), ma anche la stabilità del titolo anticorpale durante tutta la gravidanza, il recupero del feto dopo TIU e la presenza di un Test di Coombs Diretto negativo. CONCLUSIONI I quesiti che sono stati risolti in sede di taglio cesareo con la scoperta di un corioangioma gigante che, sequestrando i globuli rossi fetali, causava l’anemia e la conferma di un fenotipo sanguigno raro del padre che ha causato l’immunizzazione della donna.

description: We consider the dynamics of an electrostatically actuated thin elastic plate being clamped at its boundary above a rigid plate. While the existing literature focuses so far on a two-dimensional geometry, the present model considers a three-dimensional device where the harmonic electrostatic potential varies in the three-dimensional time-dependent region between the plates. The elastic plate deflection evolves according to a fourth-order semilinear parabolic equation which is coupled to the square of the gradient trace of the electrostatic potential on this plate. The strength of the coupling is tuned by a parameter λ proportional to the square of the applied voltage. We prove that this free boundary problem is locally well-posed in time and that for small values of λ solutions exist globally in time. We also derive the existence of a branch of asymptotically stable stationary solutions for small values of λ and non-existence of stationary solutions for large values thereof, the latter being restricted to a disc-shaped plate. © European Mathematical Society 2016.

description: In this tutorial review we present the process of the development of functional implants using mesoporous silica. The different steps from chemical synthesis and physicochemical characterization followed by in vitro testing in cell culture assays to clinically relevant in vivo animal studies are examined. Since the end of the 1990s, mesoporous silicas have been considered as biomaterials. Numerous investigations have demonstrated their non-toxic and biocompatible properties. These qualities in combination with the unique properties of high surface area and pore volume, uniform and tunable pore sizes and chemical modifiability are the reasons for the great scientific interest in this field. Here we show that besides bulk materials or mesoporous silica nanoparticles, mesoporous silica films are highly promising as coatings on medical prostheses or implants. We report on the development of functionalized mesoporous silica materials specifically for middle ear applications. Middle ear prostheses are used to restore the sound transmission through this air-filled cavity when the small bones of the middle air (the ossicular chain) have been destroyed by disease or by accidents. In addition to optimal restoration of sound transmission, this technique bears several challenges, e.g. an ongoing bacterial infection or the displacement of the prosthesis due to insufficient fixation. To improve the healing process, a mesoporous silica coating was established on ceramic middle ear prostheses, which then served as a base for further functionalizations. For example, the bone growth factor BMP2 was locally attached to the coating in order to improve the fixation of the prosthesis by forming a bony connection to the remainder of the ear bones. Further, an implant-based local drug delivery system for the antibiotic ciprofloxacin was developed with the aim of fighting bacterial infections. Further possibilities using mesoporous silica nanoparticles as part of a composite on an implant are briefly discussed. © The Royal Society of Chemistry 2013.

description: INTRODUCTION Churg-Strauss Syndrome is a rare small-vessel vasculitis associated with asthma, blood and tissue eosinophilia. Peripheral neuropathy is reported in more than 50% of cases of Churg-Strauss Syndrome and it is often found related to motor and functional recovery issues. The Sensory system plays a key role in balance control, and that is why patients with polyneuropathy experience balance impairment during stance and gait. Impairments in gait and balance are two of the main causes of the falls characterizing Churg-Strauss syndrome. Evidence suggests that exercise programs can effectively improve gait and balance and reduce falls and fall-related injuries. The purpose of this paper is to show the importance of balance focused physiotherapy interventions to provide the best functional recovery to Churg-Strauss Syndrome patients. To date, the most recent literature does not provide us with evidence focusing on rehabilitation and physiotherapy in those patients. CASE PRESENTATION A 65-year-old male affected by Churg-Strauss Syndrome was referred to our inpatient rehabilitation ward one month after the onset of symptoms. Balance and gait were assessed using Berg Balance Scale, Mini-BESTest together with Tinetti Mobility Test. The rehabilitation protocol was designed to focus on balance and proprioception training and was performed for 2 months, 5 sessions of 90 minutes/week. After one month 15 minutes of balance training with visual biofeedback using Biodex Balance System SD were included in the balance training sessions. RESULTS we performed 4 testing sessions at four different times: baseline (T0), one month after the beginning of training (T1), 2 months later the beginning (T2) and 6 months follow-up (T3). Berg Balance Scale values moved from 8 at baseline assessment to 50 at follow up assessment. Score on the Mini-BESTest showed an increase from 2 points at T0 to 24 points at T3. Tinetti Mobility Score values improved from 11 points at T0 to 24 points at T3. DISCUSSION Scores on the Berg Balance Scale, Mini-BESTest and Tinetti Mobility Test showed significant improvements on all the 4 testing sessions. CONCLUSIONS it can be thus said that rehabilitation programs focusing on balance training constitute a reliable enhancement for functional outcomes in patients affected by Churg-Strauss Syndrome. Nonetheless, further investigation on physiotherapy strategies is needed.

AGN obscuration from winds: from dusty infrared-driven to warm and X-ray photoionized

description: We present calculations of AGN winds at ~parsec scales, along with the associated obscuration. We take into account the pressure of infrared radiation on dust grains and the interaction of X-rays from a central black hole with hot and cold plasma. Infrared radiation (IR) is incorporated in radiation-hydrodynamic simulations adopting the flux-limited diffusion approximation. We find that in the range of X-ray luminosities L=0.05 - 0.6 L_edd, the Compton-thick part of the flow (aka torus) has an opening angle of approximately 72-75 degrees regardless of the luminosity. At L > 0.1 L_edd the outflowing dusty wind provides the obscuration with IR pressure playing a major role. The global flow consists of two phases: the cold flow at inclinations θ> 70 degrees and a hot, ionized wind of lower density at lower inclinations. The dynamical pressure of the hot wind is important in shaping the denser IR supported flow. At luminosities <0.1 L_edd episodes of outflow are followed by extended periods when the wind switches to slow accretion.

Are sustainable companies more likely to default? Evidence from the dynamics between credit and ESG ratings

description: We investigate the relationship between environmental, social and governance (ESG) performance and the probability of corporate credit default. By using a sample of 902 publicly-listed firms in the US from 2002 to 2017 and by converting Standard & Poor’s credit ratings into default probabilities from rating transition matrices, we find the probability of corporate credit default to be significantly lower for firms with high ESG performance. Furthermore, by expanding the time window in our regression analysis, we observe that the influence of ESG and its constituents strongly varies over time. We argue that these dynamics may be due to financial and regulatory shocks. In a sector decomposition, we additionally find that the energy sector is most influenced by ESG regarding the probability of corporate credit default. We expect an increasing availability of ESG data in the future to reduce possible survivorship bias and to enhance the comparison between ESG-rated and non-ESG-rated firms.

description: Excerpts from the report Preface: In 1964, a cooperative study was made by the U.S. Cotton Ginning Research Laboratory and the Economic Research Service at Stoneville, Miss., to develop a machine that would do an efficient job of reclaiming and cleaning fibrous material ejected from lint cleaners. The experimental machine was 72 percent efficient in fiber reclaiming ability and 84 percent efficient in cleaning ability. One phase of the 1964 study was continuous blending (during ginning) of reclaimed fiber into the original bale from which it was removed. For 5-pound spinning lots, the blending operation had little effect upon spinning quality except for a slight increase in manufacturing waste. To better evaluate effects of reclaimed gin-loss cotton on lint quality and spinning performance, a larger scale study was needed. Therefore, in 1965, a study was initiated to obtain data for a more comprehensive evaluation. This report presents the results of that evaluation.

Intermittent boundary layers and torque maxima in Taylor-Couette flow

description: Turbulent Taylor-Couette flow between counter-rotating cylinders develops intermittently fluctuating boundary layers for sufficient counter-rotation. We demonstrate the phenomenon in direct numerical simulations for radius ratios η=0.5 and 0.71 and propose a theoretical model for the critical value in the rotation ratio. Numerical results as well as experiments show that the onset of this intermittency coincides with the maximum in torque. The variations in torque correlate with the variations in mean Taylor vortex flow which is first enhanced for weak counter-rotation, and then reduced as intermittency sets in. To support the model, we compare to numerical results, experiments at higher Reynolds numbers, and to Wendt's data.

description: This paper focuses on the construction of "the people" as a narrative actor. Starting with the concept of the "empty signifier" and drawing on interpretive semiotics, specifically the idea of "semantic potential" (proposed by Umberto Eco and Patrizia Violi), the author analyzes how collective formations are shaped narratively as "the people" through the construction of a negative axis (opposition) and a positive axis (definitional traits of those belonging to the people). In the final part of the paper, the author applies this perspective to sequences from "Battleship Potemkin" (Eisenstein, 1925) and "Strike" (Eisenstein, 1925).
