description: It is unclear why racial differences exist in the frequency of surgery for lung cancer treatment. Comorbidity is an important consideration in selection of patients for lung cancer treatment, including surgery. To assess whether comorbidity contributes to the observed racial differences, we evaluated racial differences in the prevalence of comorbidity and their impact on receipt of surgery.
Literary Navigations. The Sea Imagery of Dragan Velikić
Creators: name: Leto, Maria Rita
Publisher: name: Studi Slavistici
Year: 2016

description: This article explores the function of the sea images in the fiction of the Serbian contemporary writer Dragan Velikić. The sea, a traditional symbol in world’s literature, is a key image in this writer’s texts, so much so that it amounts to nothing less than imagery of its own in his oeuvre. Imagery, however, that is very different from that handed down by the sea tradition. The author contends that the sea imagery, disseminated throughout Velikić’s works, allows the writer to create a network of intertextual references within his macro-text. At a deeper level, moreover, this imagery seems to have a twofold function in Velikić’s narrative: on the one hand, it mediates the writer’s complex relationship with the literary tradition of the past; on the other, it constitutes the core around which Velikić builds a number of virtual autobiographies: fictions conjuring up the past, both personal and cultural, permeated with auto-biographical overtones, Velikić’s stories evoke in their male protagonists various aspects of the author’s life, as well as of literary figures of the past, while never really giving rise to a full-fledged self-portrait. Thus, his stories, like ships navigating the sea, traverse several boundaries (between genres, historical and fictional self, past and present, life and literature), creating, through his idiosyncratic sea imagery, a fascinating narrative world.

The sequence of variable updating over each time steps after introducing a perturbation from the healthy state was saved as a timeseries and plotted. It shows the discrete behavior of the simulation and that a steady state is reached way before the duration of the perturbation (1000 time steps) is reached in such a way that maintain the perturbation longer would not change the output of the simulation once the perturbation is released.
Три взгляда на альтернативную Россию. Маскавская Мекка А. Волоса, День опричника В. Сорокина, Укус ангела П. Крусанова
Creators: name: Novokhatskyi, Dmytro
Publisher: name: Studi Slavistici
Year: 2016

description: The article deals with three novels representing alternate history/futurology of Russia, a popular trend in contemporary Russian fiction extrapolating actual social and political realities into the near future. All three novels depict dystopian and oppressive societies modelled on the historically known and rejected ways in which Russia has developed: the time of Ivan the Terrible, the aftershock of the collapse of the USSR, the typical Soviet Union of the 1950-70s, and the aggressive Russian Empire of the 19th century. Following the dystopian tradition, the central question is the essence of power and the relation between power and violence, institutionalized in newly-built societies, though the protagonist is no longer a ‘classical’ dystopian rebel but the average man struggling to survive (Maskavskaja Mekka) or a representative of the repressive State machine (Den’ Opričnika and Ukus Angela). Other important questions raised in the novels are the potential threat of Islamization, the territorial and cultural expansion of China, and the crisis of traditional Russian values. All three novels bear strong satirical connotations and numerous intertextual allusions to numerous works of Russian literary tradition.

description: The landscape of managing potential conflicts of interest (COIs) has evolved substantially across many disciplines in recent years, but rarely are the issues more intertwined with financial and ethical implications than in the health care setting. Cancer care is a highly technologic arena, with numerous physician-industry interactions. The American Society of Clinical Oncology (ASCO) recognizes the role of a professional organization to facilitate management of these interactions and the need for periodic review of its COI policy (Policy).

description: We study the general-relativistic dynamics of matter being accreted onto and ejected by a magnetised and nonrotating neutron star. The dynamics is followed in the framework of fully general relativistic magnetohydrodynamics (GRMHD) within the ideal-MHD limit and in two spatial dimensions. More specifically, making use of the numerical code BHAC, we follow the evolution of a geometrically thick matter torus driven into accretion by the development of a magnetorotational instability. By making use of a number of simulations in which we vary the strength of the stellar dipolar magnetic field, we can determine self-consistently the location of the magnetospheric (or Alfvén) radius $r_{\rm msph}$ and study how it depends on the magnetic moment $μ$ and on the accretion rate. Overall, we recover the analytic Newtonian scaling relation, i.e. $r_{\rm msph} \propto B^{4/7}$, but also find that the dependence on the accretion rate is very weak. Furthermore, we find that the material torque correlates linearly with the mass-accretion rate, although both of them exhibit rapid fluctuations. Interestingly, the total torque fluctuates drastically in strong magnetic field simulations and these unsteady torques observed in the simulations could be associated with the spin fluctuations observed in X-ray pulsars.

Conception of Biologic System: Basis Functional Elements and Metric Properties
Creators: name: Davydyan, Garri
Publisher: name: arXiv
Year: 2014
Subjects: subject: Other Quantitative Biology (q-bio.OT)
subject: FOS: Biological sciences

description: A notion of biologic system or just a system implies a functional wholeness of comprising system components. Positive and negative feedback are the examples of how the idea to unite anatomical elements in the whole functional structure was successfully used in practice to explain regulatory mechanisms in biology and medicine. There are numerous examples of functional and metabolic pathways which are not regulated by feedback loops and have a structure of reciprocal relationships. Expressed in the matrix form positive feedback, negative feedback, and reciprocal links represent three basis elements of a Lie algebra sl(2,R)of a special linear group SL(2,R). It is proposed that the mathematical group structure can be realized through the three regulatory elements playing a role of a functional basis of biologic systems. The structure of the basis elements endows the space of biological variables with indefinite metric. Metric structure resembles Minkowski's space-time (+, -, -) making the carrier spaces of biologic variables and the space of transformations inhomogeneous. It endows biologic systems with a rich functional structure, giving the regulatory elements special differentiating features to form steady autonomous subsystems reducible to one-dimensional components.

description: We conducted a deep XMM$\unicode{x2013}$Newton observing campaign on the 23.5-s radio pulsar PSR J0250+5854 in order to better understand the connection between long-period, radio-emitting neutron stars and their high-energy-emitting counterparts. No X-ray emission was detected resulting in an upper limit in the bolometric luminosity of PSR J0250+5854 of $<$10$^{31}$ erg s$^{-1}$ for an assumed blackbody with a temperature of 85 eV, typical of an X-ray Dim Isolated Neutron Star (XDINS). We compared the upper limit in the bolometric luminosity of PSR J0250+5854 with the known population of XDINSs and found that the upper limit is lower than the bolometric luminosity of all but one XDINS. We also compared PSR J0250+5854 with SGR 0418+5729, the magnetar with low dipole magnetic field strength, where the upper limit suggests that if PSR J0250+5854 has a thermal hot spot like SGR 0418+5729, it would have a blackbody temperature of $<$200 eV, compared to 320 eV of the magnetar.

description: The work of Adler provides necessary and sufficient conditions for the Wronskian of a given sequence of eigenfunctions of Schrödinger's equation to have constant sign in its domain of definition. We extend this result by giving explicit formulas for the number of real zeros of the Wronskian of an arbitrary sequence of eigenfunctions. Our results apply in particular to Wronskians of classical orthogonal polynomials, thus generalizing classical results by Karlin and Szegő. Our formulas hold under very mild conditions that are believed to hold for generic values of the parameters. In the Hermite case, our results allow to prove some conjectures recently formulated by Felder et al.

Genitive-Dative Syncretism in the History of the Bulgarian Language. Towards an Analysis

Publisher: name: Studi Slavistici
Year: 2016

description: In this article, we trace the diachronic phases of so-called genitive-dative syncretism in Old Bulgarian, a phenomenon which marks the beginning of the process of disintegration of the Case system in the history of Bulgarian. We base our research on a corpus study (comprising the texts of Codex Marianus, Codex Zographensis and Codex Suprasliensis) and we show, after a careful examination of the available syntactic positions for the Genitive and the Dative, that the main reason for the Dative shift in Old Bulgarian was the so-called External Possessive construction (also known as dativus sympatheticus) which allowed the dative to be interpreted outside the noun phrase but with reference to an inalienable possessive element inside the noun phrase. We discuss each stage of the functional reanalysis leading to the establishment of noun phrase internal dative possessives, and in particular the role of the emerging clitic pronouns and their second position syntactic behaviour as a main trigger of genitive-dative syncretism.

Publisher: name: Studi Slavistici
Year: 2016

description: This paper deals with listing as a useful conceptual tool for categorization and offers an overview of the different types of lists in Russian, highlighting both universal and language-specific characteristics of this kind of construction. The data-driven approach adopted in this study allows you to identify the main criteria according to which lists can be classified (exhaustiveness of the enumeration, conjunction, types of constituents, compositionality, and so on). Particular attention is paid to paradigmatic lists, i.e. lists whose items are in a paradigmatic relationship with each other as either synonyms, co-hyponyms or co-meronyms. The features of this family of lists are dealt with in the framework of Construction Grammar, which accounts for both similarities in structure and meaning and differences in pragmatic and communicative functions.

description: In the automotive sector, the demand for high crash safety and lightweight construction has led to an increased use of steels with higher strengths. However, the rising number of varying materials with different strengths and ductilities lead to an increasing complexity in productionmaking it more challenging to ensure robust processes. Therefore, the focus of current researches still lays on the further development and extension of forming processes to enable high productivity and reliable production. A powerful tool for an efficient optimisation and extension of forming processes is the Finite Element Method (FEM), which offers time-and cost saving potentials in the design phase. In deep drawing, the use of a counter punch offers the possibility oextending the process limits. By superimposing compressive stresses on the workpiece, the initiation of cracks can be delayed, thus higher drawing ratios can be achieved. The aim of this research is therefore the numerical investigation of a deep drawing process with a counter punch to analyse the influence on the crack initiation and identify optimisation potentials for the processFor this cause, the applied force as well as the position and geometry of the counter punch are varied and the influence on fracture initiation is evaluated. It is found that the applied force on the counter punch is the major influencing factor for crack initiation. Furthermore, it was concluded that the contact between the counter punch and the workpiece should be applied as soon as the bottom of the cup is shaped. A further improvement can be achieved if the counter punch is geometrically adapted to the bottom of the workpiece.
Effective temperature from fluctuation-dissipation theorem in systems with bipartite eigenmode entanglement

Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In thermal equilibrium, the fluctuation-dissipation theorem relates the linear response and correlation functions in a model and observable independent fashion. Out of equilibrium, these relations still hold if the equilibrium temperature is replaced by an observable and frequency-dependent parameter (effective temperature). When the system achieves a long time thermal state all of these effective temperatures should be equal and constant. Following this approach we examine the long times regime after a quantum quench in a system with bipartite entanglement in which the asymptotic values of the observable are compatible with the ones obtained in a Gibbs ensemble. We observe that when the initial entanglement is large, and for a large range of (intermediate) frequencies, the effective temperatures corresponding to the analyzed local and non-local operators approach an approximate constant value equal to the temperature that governs the decay of correlations. Still, the residual frequency dependence in the effective temperature, and the differences observed among observables discards strict thermalization.

description: Layered van-der-Waals materials with hexagonal symmetry offer an extra degree of freedom to their electrons, the so called valley index or valley pseudospin. This quantity behaves conceptually like the electron spin and the term valleytronics has been coined. In this context, the group of semiconducting transition-metal dichalcogenides (TMDC) are particularly appealing, due to large spin-orbit interactions and a direct bandgap at the K points of the hexagonal Brillouin zone. In this work, we present investigations of excitonic transitions in mono- and multilayer WSe$_2$ and MoSe$_2$ materials by time-resolved Faraday ellipticity (TRFE) with in-plane magnetic fields, $B_{\parallel}$, of up to 9 T. In monolayer samples, the measured TRFE time traces are almost independent of $B_{\parallel}$, which confirms a close to zero in-plane exciton $g$ factor $g_\parallel$, consistent with first-principles calculations. In stark contrast, we observe pronounced temporal oscillations in multilayer samples for $B_{\parallel}>0$. Remarkably, the extracted in-plane $g_\parallel$ are very close to reported out-of-plane exciton $g$ factors of the materials, namely $|g_{\parallel 1s}|=3.1\pm 0.2$ and $2.5\pm0.2$ for the 1s A excitons in WSe$_2$ and MoSe$_2$ multilayers, respectively. Our first-principles calculations nicely confirm the presence of a non-zero $g_{\parallel}$ for the multilayer samples. We propose that the oscillatory TRFE signal in the multilayer samples is caused by pseudospin quantum beats of excitons, which is a manifestation of spin- and pseudospin layer locking in the multilayer samples. Our results demonstrate ultrafast pseudospin rotations in the GHz- to THz frequency range, which pave the way towards ultrafast pseudospin manipulation in multilayer TMDC samples.

description: We explore local and global dynamical differences between the kinematics of ionised gas and stars in a sample of galaxies from Data Release 3 of the SAMI Galaxy Survey. We find better agreement between local (i.e., comparing on a spaxel-to-spaxel basis) velocities and dispersion of gas and stars in younger systems as with previous work on the asymmetric drift in galaxies, suggesting that the dynamics of stars and ionised gas are initially coupled. The intrinsic scatter around the velocity and dispersion relations increases with increasing stellar age and mass, suggesting that subsequent mechanisms such as internal processes, divergent star formation and assembly histories also play a role in setting and altering the dynamics of galaxies. The global (flux-weighted) dynamical support of older galaxies is hotter than in younger systems. We find that the ionised gas in galaxies is almost always dynamically colder than the stars with a steeper velocity gradient. In absolute terms, the local difference in velocity dispersion is more pronounced than the local difference in velocity, possibly reflecting inherent differences in the impact of turbulence, inflow and/or feedback on gas compared to stars. We suggest how these findings may be taken into account when comparing high and low redshift galaxy samples to infer dynamical evolution.

description: We review recent experimental results indicating the band flattening and Landau level merging at the chemical potential in strongly-correlated two-dimensional (2D) electron systems. In ultra-clean, strongly interacting 2D electron system in SiGe/Si/SiGe quantum wells, the effective electron mass at the Fermi level monotonically increases in the entire range of electron densities, while the energy-averaged mass saturates at low densities. The qualitatively different behavior of the two masses reveals a precursor to the interaction-induced single-particle spectrum flattening at the chemical potential in this electron system, in which case the fermion "condensation" at the Fermi level occurs in a range of momenta, unlike the condensation of bosons. In strong magnetic fields, perpendicular to the 2D electron layer, a similar effect of different fillings of quantum levels at the chemical potential -- the merging of the spin- and valley-split Landau levels at the chemical potential -- is observed in Si inversion layers and bilayer 2D electron system in GaAs. Indication of merging of the quantum levels of composite fermions with different valley indices is also reported in ultra-clean SiGe/Si/SiGe quantum wells.

Il concetto di fratellanza nel testo poetico di Taras Ševčenko
Creators: name: Goletiani, Liana
Publisher: name: Studi Slavistici
Year: 2016

description: The Author analyzes the linguo-culturological idea of “brotherhood” in both Ukrainian language and Russian language works by Ševčenko. This word and its related metaphorical meanings are a central poetic instrument of Ševčenko’s literary works and connect them with the ancient traditions of Ukrainian folklore and religious beliefs. Together with the opposite idea of “discordance”, the idea of “brotherhood” is an important tool for the mythological reconstruction of Ukrainian history and of the poet’s philosophical and ideological message. A lexical analysis of the concept of “brotherhood” indicates that the term was very frequent and had numerous nuances in Ukrainian poems, while it was rather rare and semantically limited in the Russian works. The Author offers a lexicographic definition of the key-words, then describes their linguistic function, and syntagmatic, paradygmatic and associative relationships with semantic analysis procedures. Among the associated ideas, national and social liberty are dominant. Here too the differentiation of Ukrainian and Russian works is evident: the conceptualization of the associated terms is similar when it invests the Christian semantic field, but is significantly different when it concerns historical and social issues.

description: The article discusses the significance of Ukraine’s national poet Taras Ševčenko for the history of the Ukrainian standard language. By the time the poet published his works, Ukrainian had still not been developed into a modern standard language. Although Ševčenko himself did not establish Modern Standard Ukrainian, his significance for its further development was decisive, because it was precisely his language that served as a model for the other writers (including those from other dialect areas), and for the codifiers of the Ukrainian language as well.

description: In the present work, the flat FLRW Universe has been modelled with cosmic matter in the form of diffusive barotropic fluid. The diffusive fluid undergoes dissipation due to diffusion mechanism in the form of cosmological scalar field. From the perspective of non-equilibrium thermodynamics, the evolution equations of the universe have been formulated. By a suitable choice of the cosmological scalar field, emergent scenario of the universe has been obtained.
Shevchenko´s Hajdamaks in Literary Context
Creators: name: Woldan, Alois
Publisher: name: Studi Slavistici
Year: 2016

description: The article attempts to place Shevchenko’s poem on the 1768 Hajdmak-uprising into a wider context, establishing relations with works on this subject which the Ukrainian poet may have known or probably did not know. These are first of all Polish works (Goszczynki´s poem Kaniow-Castle, Czajkowki’s novel Wernyhora). It also examines links with historiographic texts which appeared much later than the aforementioned literary works. An essential part of the “Hajdamak-text” is its Russian component, consisting of novels written by authors of Ukrainian origin, such as V. Narežnyj and O. Somov. There is one more link to Galician literature, where German as well as Ukrainian authors point out the connection between Galician “Opryšky” and Ukrainian “Hajdamaky”.

La ballata Topolja di Taras Ševčenko. Una prospettiva comparatistica
Creators: name: Simonek, Stefan
Publisher: name: Studi Slavistici
Year: 2016

description: The paper offers a short analysis of the main subject in Taras Ševčenko’s famous ballad Topolja from 1839; in the ballad, a young girl forced to marry an older man by her own mother asks nature for help and, eventually, finds herself turned into a slim poplar. In Ukrainian philology, Ševčenko’s poetic masterpiece was initially compared to similar subjects in Ukrainian folk songs. Ivan Franko, however, already in 1890 also mentioned ancient Greek and Roman literature and Russian and Polish Romanticism as a broader European context for Topolja. Underlining this broader European approach as offered by Franko, the paper delivers further material from Greek, Russian, Slovene, and German literature from Homer and Aleksandr S. Puškin up to the German expressionist poet Georg Heym. The various works of all these writers clearly demonstrate that comparing a girl with a poplar was a poetic subject used at least up until the beginning of the 20th century. Next to this, the comparison as introduced into Ukrainian literature by Taras Ševčenko in 1839, is also typical of Pavlo Tyčyna’s early collections of poems, which are now appreciated as masterpieces of Ukrainian modernism.

description: One of the outstanding questions in the study of twisted bilayer graphene -- from both experimental and theoretical points of view -- is the nature of its superconducting phase. In this work we perform a comprehensive synthesis of existing experiments, and argue that experimental constraints are strong enough to allow the structure of the superconducting order parameter to be nearly uniquely determined. In particular, we argue that the order parameter is nodal, and is formed from an admixture of spin-singlet and spin-triplet Cooper pairs. This argument is made on phenomenological grounds, without committing to any particular microscopic model of the superconductor. Existing data is insufficient to determine the orbital parity of the order parameter, which could be either p-wave or d-wave. We propose a way in which the measurement of Andreev edge states can be used to distinguish between the two.

description: After nearly half a century of research into the bias temperature instability (BTI), two classes of models have emerged as the strongest contenders: one class of models, the reaction-diffusion models, is built around the idea that hydrogen is released from the interface and that it is the diffusion of some form of hydrogen that controls both degradation and recovery. While many different variants of the reaction-diffusion idea have been published over the years, the most commonly used recent models are based on non-dispersive reaction rates and non- dispersive diffusion. The other class of models is based on the idea that degradation is controlled by first-order reactions with widely distributed (dispersive) reaction rates. We demonstrate that these two classes give fundamentally different predictions for the stochastic degradation and recovery of nanoscale devices, therefore providing the ultimate modeling benchmark. Using de- tailed experimental time-dependent defect spectroscopy (TDDS) data obtained on such nanoscale devices, we investigate the compatibility of these models with experiment. Our results show that the diffusion of hydrogen (or any other species) is unlikely to be the limiting aspect that determines degradation. On the other hand, the data are fully consistent with reaction-limited models. We finally argue that only the correct understanding of the physical mechanisms leading to the significant device-to-device variation observed in the degradation in nanoscale devices will enable accurate reliability projections and device optimization.

description: Optimal adjuvant chemotherapy for early-stage breast cancer balances efficacy and toxicity. We sought to determine whether single-agent paclitaxel (T) was inferior to doxorubicin and cyclophosphamide (AC), when each was administered for four or six cycles of therapy, and whether it offered less toxicity.
Taras Ševčenko in the Prose and Poetry of Vasyl’ Stus

Publisher: name: Studi Slavistici
Year: 2016

description: The presence of Ševčenko in the poetry of Vasyl’ Stus and Stus’s widespread stereotypical image as a reincarnation of Ševčenko in the 20th century have occupied an important role in both literary studies and popularization. In my article I reconsider this fundamental issue by discussing Stus’s reception of Ševčenko in his critical essays, his letters, and his poetry. My focus is on both Ševčenko’s presence as a ‘fictional character’ in some poems by Stus and the overall influence of Ševčenko’s poetry on Stus’s poetic writing. Moreover, Stus’s representation of Ševčenko is compared with other images of the 19th-century poet in modern Ukrainian poetry from the Avant-garde up to the Seventies. In the conclusion I point out how Ševčenko’s Romanticism should not be confused with Stus’s Modernism. The former should be seen as a part of the complex intertextual mechanism which lies at the heart of Stus’s poetry.

description: This work presents the results from extending the long-term monitoring program of stellar motions within the Galactic Center to include stars with separations of 2 - 7 arcseconds from the compact radio source, Sgr A*. In comparison to the well studied inner 2 arcsec, a longer baseline in time is required to study these stars. With 17 years of data, a sufficient number of positions along the orbits of these outer stars can now be measured. This was achieved by designing a source finder to track the positions of ~ 2000 stars in NACO/VLT adaptive-optics-assisted images of the Galactic Center from 2002 to 2019. Of the studied stars, 54 exhibit significant accelerations toward Sgr A*, most of which have separations of between 2 and 3 arcseconds from the black hole. A further 20 of these stars have measurable radial velocities from SINFONI/VLT stellar spectra, which allows for the calculation of the orbital elements for these stars, thus increasing the number of known orbits in the Galactic Center by ~ 40 %. With orbits, we can consider which structural features within the Galactic Center nuclear star cluster these stars belong to. Most of the stars have orbital solutions that are consistent with the known clockwise rotating disk feature. Further, by employing Monte Carlo sampling for stars without radial velocity measurements, we show that many stars have a subset of possible orbits that are consistent with one of the known disk features within the Galactic Center.

Taras Ševčenko on Majdan
Creators: name: Siedina, Giovanna
Publisher: name: Studi Slavistici
Year: 2016

description: The author illustrates the different ways in which the Ukrainian national poet Taras Ševčenko was ‘used’ by participants in the protest movement known as Jevromajdan (Euromaidan) (November 2013-February 2014). In particular the author analyzes quotations and adaptations of Ševčenko’s poetry, portrayals of the poet himself (paintings, photomontages, sculptures), and poems inspired by him and conceived as a sort of dialogue with him. The aforementioned uses of Ševčenko are investigated with regard to their function in supporting the protesters’ claims and reasons for discontent, also taking into account the inextricable and unique bond that links Ukraine and Ukrainians with the human, moral and poetic legacy of Taras Ševčenko.

Solutions to the relativistic precession model

description: The relativistic precession model (RPM) can be used to obtain a precise measurement of the mass and spin of a black hole when the appropriate set of quasi periodic oscillations is detected in the power-density spectrum of an accreting black hole. However, in previous studies the solution of the RPM equations could be obtained only through numerical methods at a price of an intensive computational effort. Here we demonstrate that the RPM system of equations can be solved analytically, drastically reducing the computational load, now limited to the Monte-Carlo simulation necessary to estimate the uncertainties. The analytical method not only provides an easy solution to the RPM system when three oscillations are detected, but in all the cases where the detection of two simultaneous oscillations is coupled with an independent mass measurement. We also present a computationally inexpensive method to place limits on the black hole mass and spin when only two oscillations are observed.

description: Human figures have been animated using a variety of geometric models including stick figures, polygonal models, and NURBS-based models with muscles, flexible skin, or clothing. This paper reports on experimental results indicating that a viewer's perception of motion characteristics is affected by the geometric model used for rendering. Subjects were shown a series of paired motion sequences and asked if the two motions in each pair were the same or different. The motion sequences in each pair were rendered using the same geometric model. For the three types of motion variation tested, sensitivity scores indicate that subjects were better able to observe changes with the polygonal model than they were with the stick figure model.

Dust in AGB wind-ISM interaction regions

description: We aim to constrain the dust mass and grain sizes in the interaction regions between the stellar winds and the ISM around asymptotic giant branch stars. By describing the dust in these regions, we aim to shed light on the role of low mass evolved stars in the origin of dust in galaxies. We use images in the far-infrared at 70 micron and 160 micron to derive dust temperatures and dust masses in the wind-ISM interaction regions around a sample of carbon-rich and oxygen-rich asymptotic giant branch (AGB) stars. The dust temperature and mass are determined in two ways. First directly from the data using the ratio of the measured fluxes and assuming opacities for dust with a constant grain size of 0.1 micron. We then perform 3D dust-radiative transfer models spatially constrained by the observations to consistently calculate the temperature and mass. For the radiative transfer models each model contains one constant grain size, which is varied between 0.01 micron to 5.0 micron. We find that the observed dust mass in the wind-ISM interaction regions is consistent with mass accumulated from the stellar winds. For the carbon-rich sources adding the spatial constraints in the radiative transfer models results in preferentially larger grain sizes (approx. 2 micron). For the oxygen-rich sources the spatial constraints result in too high temperatures in the models, making it impossible to fit the observed far-infrared ratio irrespective of the grain size used, indicating a more complex interplay of grain properties and the stellar radiation field. The results have implications for how likely it is for the grains to survive the transition into the ISM, and the properties of dust particles that later act as seeds for grain growth in the ISM. However, the results for the oxygen-rich sources show that the derivation of dust properties is not straight forward, requiring more complex modelling

Violation of the Spin Statistics Theorem and the Bose-Einstein Condensation of Particles with Half Integer Spin

description: We consider the Bose condensation of particles with spin 1/2. The condensation is driven by an external magnetic field. Our work is motivated by ideas of quantum critical deconfinement and bosonic spinons in spin liquid states. We show that both the nature of the novel Bose condensate and the excitation spectrum are fundamentally different from that in the usual integer spin case. We predict two massive ("Higgs") excitations and two massless Goldstone excitations. One of the Goldstone excitations has a linear excitation spectrum and another has quadratic spectrum. This implies that the Bose condensate does not support superfluidity, the Landau criterion is essentially violated. We formulate a "smoking gun" criterion for searches of the novel Bose condensation.
