Spectral evolution and radial dust transport in the disk of the prototype young eruptive star EX Lup
Creators: name: Chen, Lei
Publisher: name: Zenodo
Year: 2018

description: During the outbursts of EXor stars, the enhanced illumination from the central region heats the inner disk surface within 1 au to a high temperature, permitting pristine amorphous silicate grains to anneal into crystalline ones. The first direct evidence of this process was the discovery of crystalline features in our Spitzer spectrum of the prototype star EX Lup during its 2008 outburst. Our VLTI/MIDI observation during the outburst constrained that the newly formed crystals are in a compact region within 1 au. We analyzed post-outburst Spitzer, VLTI/MIDI, and new VLT/VISIR data and found that the crystalline silicate features faded with time and finally disappeared within several years after the outburst. We interpret the temporal change of the spectrum with a scenario that the crystalline silicate grains created in the inner region are transported outwards, forming a crystal-rich expanding shell. Our radiative transfer modeling successfully reproduced the features in the post-outburst spectra. The mass of crystal grains in our model is consistent with an origin in the heated inner disk surface. The expanding velocity of the shell is also constrained.

description: Composite Higgs models can trivially satisfy precision-electroweak and flavour constraints by simply having a large spontaneous symmetry breaking scale, f > 10 TeV. This produces a 'split' spectrum, where the strong sector resonances have masses greater than 10 TeV and are separated from the pseudo Nambu-Goldstone bosons, which remain near the electroweak scale. Even though a tuning of order 10^{-4} is required to obtain the observed Higgs boson mass, the big hierarchy problem remains mostly solved. Intriguingly, models with a fully-composite right-handed top quark also exhibit improved gauge coupling unification. By restricting ourselves to models which preserve these features we find that the symmetry breaking scale cannot be arbitrarily raised, leading to an upper bound f < 100-1000 TeV. This implies that the resonances may be accessible at future colliders, or indirectly via rare-decay experiments. Dark matter is identified with a pseudo Nambu-Goldstone boson, and we show that the smallest coset space containing a stable, scalar singlet and an unbroken SU(5) symmetry is SU(7) / SU(6) x U(1). The colour-triplet pseudo Nambu-Goldstone boson also contained in this coset space is metastable due to a residual symmetry. It can decay via a displaced vertex when produced at colliders, leading to a distinctive signal of unnaturalness.

description: Diese Arbeit beschäftigt sich mit unterschiedlichen Konzeptionen des expliziten bzw. impliziten Gehalts sprachlicher Äußerungen. Dabei wird einerseits die pragmatische Konversationstheorie (Grice, 1989) der kognitionswissenschaftlichen Relevanztheorie (Wilson & Sperber, 1986) gegenüberstellt und andererseits Ansätze, welche sich zwischen Grice (1989) und Wilson und Sperber (1986) bewegen, diskutiert (Bach, 1994; Saul, 2012). Anschließend werden kontextuelle Bedeutungserweiterungen anhand konkreter Beispiele hinsichtlich ihrer Positionierung entlang des Explizit-/Implizit-Kontinuums analysiert und diskutiert. Als sprachliches „Testgelände“ dienen dabei Lügen und Täuschungen bzw. Irreführungen. Auf Basis der Ergebnisse wird für ein 3-Stufen-Modell plädiert, welches zwischen dem strikt wahrheitsbedingendem Gehalt (logical truth-conditional content) und dem gänzlich inferierten impliziten Gehalt (implicit content) ein intermediäres Level (intuitive truth-conditional content) vorsieht. Dieses definiert sich als neue Konzeption von „what is said“, ist als Teil des expliziten Gehalts sprachlicher Äußerungen zu verstehen und beherbergt kontextkonstante Bedeutungserweiterungen wie die Füllung impliziter Argumentstellen sowie die Erstellung generalisierter Im- bzw.

description: We compute the critical temperature for the chiral transition in the background of a magnetic field in the linear sigma model, including the quark contribution and the thermo-magnetic effects induced on the coupling constants at one loop level. We show that the critical temperature decreases as a function of the field strength. The effect of fermions on the critical temperature is small and the main effect on this observable comes from the charged pions. The findings support the idea that the anticatalysis phenomenon receives a contribution due only to quiral symmetry effects independent of the deconfinement transition.

description: We present a phenomenological modification of the standard perturbation theory prediction for the bispectrum in redshift space that allows us to extend the model to mildly non-linear scales over a wide range of redshifts, $z\leq1.5$. We find that we can describe the bispectrum of dark matter particles with $\sim5%$ accuracy for $k_i\lesssim0.10\,h/{\rm Mpc}$ at $z=0$, for $k_i\lesssim0.15\,h/{\rm Mpc}$ at $z=0.5$, for $k_i\lesssim0.17\,h/{\rm Mpc}$ at $z=1.0$ and for $k_i\lesssim0.20\,h/{\rm Mpc}$ at $z=1.5$. We also test that the fitting formula is able to describe with similar accuracy the bispectrum of cosmologies with different $Ω_m$, in the range $0.2\lesssim Ω_m \lesssim 0.4$, and consequently with different values of the logarithmic grow rate $f$ at $z=0$, $0.4\lesssim f(z=0) \lesssim 0.6$. We apply this new formula to recover the bias parameters, $f$ and $σ_8$, by combining the redshift space power spectrum monopole and quadrupole with the bispectrum monopole for both dark matter particles and haloes. We find that the combination of these three statistics can break the degeneracy between $b_1$, $f$ and $σ_8$. For dark matter particles the new model can be used to recover $f$ and $σ_8$ with $\sim1%$ accuracy. For dark matter haloes we find that $f$ and $σ_8$ present larger systematic shifts, $\sim10%$. The systematic offsets arise because of limitations in the modelling of the interplay between bias and redshift space distortions, and represent a limitation as the statistical errors of forthcoming surveys reach this level. Conveniently, we find that these residual systematics are mitigated for combinations of parameters. The improvement on the modelling of the bispectrum presented in this paper will be useful for extracting information from current and future galaxy surveys. [abridged]

Brainfuck“, Roman Ehrlichs „Malé“ und Michel Houellebecqs „La Possibilité d’une île“ zu untersuchen. Da allen drei Werken die Gattung der Dystopie gemein ist, wird auf deren Entstehung und damit auf die Utopie eingegangen. Da die Dystopie die außertextuelle Wirklichkeit durch die Darstellung der Problematiken in der Er- zählwelt zu kritisieren sucht, wird, darauf aufbauend, die Heterotopie thematisiert, da sie als Ort des Dazwischens Raum für Veränderung schafft. Die Form der Kritik, ihre Wirkung auf die Rezipient*innen wird durch die Analyse des Dargestellten wie der sprachlichen Untersu- chung ersichtlich.

description: We present Cholla (Computational Hydrodynamics On ParaLLel Architectures), a new three-dimensional hydrodynamics code that harnesses the power of graphics processing units (GPUs) to accelerate astrophysical simulations. Cholla models the Euler equations on a static mesh using state-of-the-art techniques, including the unsplit Corner Transport Upwind (CTU) algorithm, a variety of exact and approximate Riemann solvers, and multiple spatial reconstruction techniques including the piecewise parabolic method (PPM). Using GPUs, Cholla evolves the fluid properties of thousands of cells simultaneously and can update over ten million cells per GPU-second while using an exact Riemann solver and PPM reconstruction. Owing to the massively-parallel architecture of GPUs and the design of the Cholla code, astrophysical simulations with physically interesting grid resolutions (> 256^3) can easily be computed on a single device. We use the Message Passing Interface library to extend calculations onto multiple devices and demonstrate nearly ideal scaling beyond 64 GPUs. A suite of test problems highlights the physical accuracy of our modeling and provides a useful comparison to other codes. We then use Cholla to simulate the interaction of a shock wave with a gas cloud in the interstellar medium, showing that the evolution of the cloud is highly dependent on its density structure. We reconcile the computed mixing time of a turbulent cloud with a realistic density distribution destroyed by a strong shock with the existing analytic theory for spherical cloud destruction by describing the system in terms of its median gas density.

For inverse temperatures above 1, all of the extremal KMS states are of type I$_\infty$. At inverse temperature 1, there is a dichotomy: if the $k$-graph is a simple $k$-dimensional cycle, we obtain a finite type I factor; otherwise we obtain a type III factor, whose Connes invariant we compute in terms of the spectral radii of the coordinate matrices and the degrees of cycles in the graph.

Gas and multi-species dust dynamics in viscous discs: the importance of the dust back-reaction
Creators: name: Dipierro, Giovanni
Publisher: name: Zenodo
Year: 2018

description: We study the dynamics of a viscous protoplanetary disc hosting a population of dust grains with a range of sizes. We compute steady-state solutions, and show that the radial motion of both the gas and the dust can deviate substantially from those for a single-size dust population. Although the aerodynamic drag from the dust on the gas is weaker than in the case where all grains are optimally coupled to the gas, the cumulative ``back-reaction'' of the particles can still alter the gas dynamics significantly. In typical protoplanetary discs, the net effect of the dust back-reaction decreases the gas accretion flow compared to the dust-free (viscous) case, even for dust-to-gas ratios of order $1\%$. In the outer disc, where dust grains are typically less strongly coupled to the gas and settle towards the midplane, the dust back-reaction can even drive outward gas flow. The resulting dust and gas dynamics can give rise to observable structures, such as gas and dust cavities. Our results show that the dust back-reaction can play a major role in both the dynamics and observational appearance of protoplanetary discs, and cannot be ignored in models of protoplanetary disc evolution.

description: Rodent studies are a vital step in the development of novel anticancer therapeutics and are used in pharmacokinetic (PK), toxicology, and efficacy studies. Traditionally, anticancer drug development has relied on xenograft implantation of human cancer cell lines in immunocompromised mice for efficacy screening of a candidate compound. The usefulness of xenograft models for efficacy testing, however, has been questioned, whereas genetically engineered mouse models (GEMMs) and orthotopic syngeneic transplants (OSTs) may offer some advantages for efficacy assessment. A critical factor influencing the predictability of rodent tumor models is drug PKs, but a comprehensive comparison of plasma and tumor PK parameters among xenograft models, OSTs, GEMMs, and human patients has not been performed.

description: We study vortex solutions in a theory with dynamics governed by two weakly coupled Abelian Higgs models, describing a hidden sector and a visible sector. We analyze the radial dependence of the axially symmetric solutions constructed numerically and discuss the stability of vortex configurations for different values of the model parameters, studying in detail vortex decay into lower energy configurations. We find that even in a weak coupling regime vortex solutions strongly depend on the parameters of both the visible and hidden sectors. We also discuss on qualitative grounds possible implications of the existence of a hidden sector in connection with superconductivity.

A note on the propagation of quantized vortex rings through a quantum turbulence tangle: Energy transport or energy dissipation?

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We investigate quantum vortex ring dynamics at scales smaller than the inter-vortex spacing in quantum turbulence. Through geometrical arguments and high resolution numerical simulations we examine the validity of simple estimates of the mean free path and the structure of vortex rings post-reconnection. We find that a large proportion of vortex rings remain coherent objects where approximately $75\%$ of their energy is preserved. This leads us to consider the effectiveness of energy transport in turbulent tangles. Moreover, we show that in low density tangles, appropriate for the ultra-quantum regime, ring emission cannot be ruled out as an important mechanism for energy dissipation. However at higher vortex line densities, typically associated with the quasi-classical regime, loop emission is expected to make a negligible contribution to energy dissipation, even allowing for the fact that our work shows rings can survive multiple reconnection events. Hence the Kelvin wave cascade seems the most plausible mechanism leading to energy dissipation.

Forbidden Lines and Disk Winds
Creators: name: Edwards, Suzan
Publisher: name: Zenodo
Year: 2018

description: Low excitation optical forbidden lines are one of the defining characteristics of accreting T Tauri stars. These lines are predominantly blueshifted, indicating winds and disk occultation, with profiles that can be decomposed into kinematic components attributed to high velocity collimated jets (HVC) and lower velocity disk winds (LVC). Recently the LVC has been further decomposed into two further kinematic components, a broad one (BC) attributed to an inner disk wind and a narrow one (NC) attributed to a slower outer disk wind. Using high resolution spectra from Keck's HIRES and Magellan's MIKE spectrograph for a sample of 65 T Tauri stars, 48 of which also include [SII 4068] as well as [OI 6300 and [OI 5577], we make a detailed comparison of these various kinematic components both with each other and with additional system properties such as inclination, accretion luminosity, and disk structure. Two important new findings are establishing a connection between the properties of the HVC and the LVC that point to a physical link between them, and determining forbidden line ratios that demonstrate the LVC components arise under conditions of thermal excitation, allowing mass loss rat
Interferometric observations of the circumstellar disk environments in close binary stars
Creators: name: Eupen, Fabio
Publisher: name: Zenodo
Year: 2018

description: The inner structure of protoplanetary disks can be strongly affected by the presence of the companion in close binary stars with ~au separation, where the dispersal of the circumstellar components may occur over time scales as short as 10000 yrs. The interferometric view helps us to understand better the disk-binary interaction in such systems. We present multi epoch interferometric observations of disks in close binaries based on VLTI-MIDI (mid-IR), AMBER and GRAVITY (near-IR) data in the continuum, combined with photometric measurements. The optimization of temperature gradient models based on Markov Chain Monte Carlo simulations suggests the presence of hot dust within the circumbinary cavity for at least two of our studied objects, the ~7 au Herbig V892 Tau and the ~1 au T Tauri WW Cha at an age of ~2 Myr. In the latter case, our findings are consistent with circumstellar dust surrounding each of the binary components. Such studies are a good test-bench for theoretical models that predominantly predict rapid disrupting of the circumstellar disks.

title: Zukunftsvorstellungen im Vergleich zu tatsächlichen Zukunftsperspektiven von Migrantenkindern in Wien
Creators: name: Lintner, Anita

description: 2019 wies 45,9 Prozent der Bevölkerung in Wien einen Migrationshintergrund auf. Damit ist der Anteil der Bevölkerung mit Migrationshintergrund in Wien beinahe dop-pelt so hoch als im Rest Österreich und macht fast die Hälfte der Bevölkerung in Wien aus. In den Wiener Schulen stellt sich die Situation nicht viel anders dar. 52,5 Prozent der Schüler/innen in Wien hatte im Schuljahr 2018/19 eine andere Um-gangssprache als Deutsch, in Wiener Mittelschulen liegt der Anteil sogar bei 75,6 Prozent. Die Integrationsforschung beschäftigt sich oftmals mit Zahlen zu den Chan-cen von Kindern mit Migrationshintergrund. So ist es zum Beispiel kein Geheimnis, dass Kinder mit Migrationshintergrund nicht die gleichen Bildungschancen in Öster-reich haben, wie Kinder, die aus Österreich stammen. Umso interessanter wird die Frage, vor allem für zukünftige Lehrer/innen in Wien, welche Vorstellungen Migran-tenkinder in Wien bezüglich ihrer Zukunft in Österreich haben und welche Hoffnun-gen sie an unser Land stellen. Mit diesen Fragen soll sich diese Forschungsarbeit beschäftigen. Es sollen die Zukunftsvorstellungen von Migrantenkindern im Alter von 10 – 16 Jahren aus einer Mittelschule in Wien erhoben werden und diese anschlie-ßend mit den Perspektiven und Chancen, welche aus bestehenden Studienergebnis-sen erhoben werden, verglichen werden, um eine Relation zwischen den Wünschen der Schüler/innen und bestehenden Daten herzustellen. Zentrale Themen sollen der Bildungsweg, sowie das Heiratsverhalten und die Kinderzahl darstellen. Die vorliegende Arbeit erhebt qualitative Daten in Form von Interviews zu den priva-ten und beruflichen Perspektiven von Kindern mit Migrationshintergrund. Die Frage lautet: Stimmen die Ansprüche der Jugendlichen mit Migrationshintergrund mit ihren tatsächlichen Perspektiven überein?
Revealing the true nature of high-mass YSO jets
Creators: name: Fedriani, Ruben
Publisher: name: Zenodo
Year: 2018

description: In contrast with low-mass young stellar objects (LMYSOs), very little is known about high-mass YSOs (HMYSOs). Latest results indicate that HMYSOs might be born in a similar way as LMYSOs, i.e., through disc accretion and jet ejection. HMYSOs are deeply embedded in their parent cloud and are at kpc distance, hindering direct imaging of their accretion discs. Jets then become essential to understand the physical properties of the central source. High-resolution near-IR VLT instruments allow us to study HMYSO jets down to au scales and compare them with the low-mass regime. In this talk, I will present VLT/ISAAC, SINFONI, and CRIRES results on two HMYSOs. Spectro-astrometry is used to retrieve information about the jet down to mas scales (~tens of au at kpc distance). High-resolution spectroscopy allows us to retrieve the kinematic and dynamic properties of the massive jets. Additionally, HST imaging in the [FeII] shows the jet structure close to the star. Finally, these properties are compared with low-mass jets, suggesting that the formation of HMYSOs might be just a scaled-up version of their low-mass counterparts, and their properties scale with mass.

description: Cervical cancer is the leading cause of cancer mortality in India, accounting for 17% of all cancer deaths among women aged 30 to 69 years. At current incidence rates, the annual burden of new cases in India is projected to increase to 225,000 by 2025, but there are few large-scale, organized cervical cancer prevention programs in the country. We conducted a review of the cervical cancer prevention research literature and programmatic experiences in India to summarize the current state of knowledge and practices and recommend research priorities to address the gap in services. We found that research and programs in India have demonstrated the feasibility and acceptability of cervical cancer prevention efforts and that screening strategies requiring minimal additional human resources and laboratory infrastructure can reduce morbidity and mortality. However, additional evidence generated through implementation science research is needed to ensure that cervical cancer prevention efforts have the desired impact and are cost-effective. Specifically, implementation science research is needed to understand individual- and community-level barriers to screening and diagnostic and treatment services; to improve health care worker performance; to strengthen links among screening, diagnosis, and treatment; and to determine optimal program design, outcomes, and costs. With a quarter of the global burden of cervical cancer in India, there is no better time than now to translate research findings to practice. Implementation science can help ensure that investments in cervical cancer prevention and control result in the greatest impact.

description: Deterministic quantum computation with one quantum bit (DQC1) is a restricted model of quantum computing where the input state is the completely mixed state except for a single clean qubit, and only a single output qubit is measured at the end of the computing. It is proved that the restriction of quantum computation to the DQC1 model does not change the complexity classes NQP and SBQP. As a main consequence, it follows that the DQC1 model cannot be efficiently simulated by classical computers unless the polynomial-time hierarchy collapses to the second level (more precisely, to AM), which answers the long-standing open problem posed by Knill and Laflamme under the very plausible complexity assumption. The argument developed in this paper also weakens the complexity assumption necessary for the existing impossibility results on classical simulation of various sub-universal quantum computing models, such as the IQP model and the Boson sampling.

description: In this paper we compute extension groups in the category of strict polynomial superfunctors and thereby exhibit certain "universal extension classes" for the general linear supergroup. Some of these classes restrict to the universal extension classes for the general linear group exhibited by Friedlander and Suslin, while others arise from purely super phenomena. We then use these extension classes to show that the cohomology ring of a finite supergroup scheme---equivalently of a finite-dimensional cocommutative Hopf superalgebra---over a field is a finitely-generated algebra. Implications for the rational cohomology of the general linear supergroup are also discussed.

description: For an unbounded operator $S$ on a Banach space the existence of invariant subspaces corresponding to its spectrum in the left and right half-plane is proved. The general assumption on $S$ is the uniform boundedness of the resolvent along the imaginary axis. The projections associated with the invariant subspaces are bounded if $S$ is strictly dichotomous, but may be unbounded in general. Explicit formulas for these projections in terms of resolvent integrals are derived and used to obtain perturbation theorems for dichotomy. All results apply, with certain simplifications, to bisectorial operators.

description: Calcium-aluminium- rich inclusions (CAIs) believed to have condensed from a hot metal-rich gas close to the protosun, but no coherent formation theory exists. We present a novel detailed microphysical description of CAI condensation embedded in a state-of-the-art numerical model of star formation. Our model can explain the meteoritic evidence representing a strong constraint for future global simulations of Solar System formation.

description: Hepatocellular carcinoma (HCC) is a significant cause of death worldwide. HCC is a highly vascular tumor, and proangiogenic cytokines such as vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and fibroblast growth factor may play crucial roles in this disease. Sorafenib, a multikinase inhibitor that blocks VEGF and PDGF signaling, was the first systemic therapy to demonstrate improved survival in patients with advanced HCC. Several other drugs targeting VEGF are in development. Because of the anticipation of eventual resistance to anti-VEGF therapies, drugs that also target alternative proangiogenic pathways are being investigated. Recent clinical and preclinical data along with ongoing studies are reviewed.
YSO Variability as seen with VVV and UKIDSS
Creators: name: Lucas, Philip
Publisher: name: Zenodo
Year: 2018

description: The VISTA Variables in the Via Lactea Survey (VVV) provides a 5 year time series of 2 micron photometry for YSOs across a large part of the Galactic plane. This, along with the two-epochs of UKIDSS GPS data in the north, has provided the first large samples of highly variable YSOs (Delta K = 1 to 5 mag). The observed variability probes processes in the inner accretion disc that cause changes in accretion rate or variable extinction. Gravitational instabilities on larger scales may also be involved. We present new results, including a much enlarged sample of YSOs with Delta K above 3 mag. We also introduce the ongoing VVVX extension to VVV.
Anonymity at Risk? Assessing Re-Identification Capabilities of Large Language Models
Creators: name: Nyffenegger, Alex
Publisher: name: Zenodo

description: Anonymity of both natural and legal persons in court rulings is a critical aspect of privacy protection in the European Union and Switzerland. With the advent of LLMs, concerns about large-scale re-identification of anonymized persons are growing. In accordance with the Federal Supreme Court of Switzerland, we explore the potential of LLMs to re-identify individuals in court rulings by constructing a proof-of-concept using actual legal data from the Swiss federal supreme court. Following the initial experiment, we constructed an anonymized Wikipedia dataset as a more rigorous testing ground to further investigate the findings. With the introduction and application of the new task of re-identifying people in texts, we also introduce new metrics to measure performance. We systematically analyze the factors that influence successful re-identifications, identifying model size, input length, and instruction tuning among the most critical determinants. Despite high re-identification rates on Wikipedia, even the best LLMs struggled with court decisions. The complexity is attributed to the lack of test datasets, the necessity for substantial training resources, and data sparsity in the information used for re-identification. In conclusion, this study demonstrates that re- identification using LLMs may not be feasible for now, but as the proof-of-concept on Wikipedia showed, it might become possible in the future. We hope that our system can help enhance the confidence in the security of anonymized decisions, thus leading to the courts being more confident to publish decisions.

description: This document introduces the Universal Mathematical Entropy Computation (UMEC) framework—an entirely new class of mathematics that replaces iterative solving with entropy-weighted, non-iterative resolution. UMEC was not created as an isolated method, but emerged as a necessary component of the Pan Framework, a unified mathematical structure that explains the behavior of the physical universe through structured resonance, wave interference, and harmonic modulation.

In the Pan framework, all physical constants, forces, and structures arise from oscillatory processes embedded in the vacuum (Q-Epsilon). To model such systems with fidelity, traditional stepwise computation is insufficient. UMEC resolves this by collapsing equations into single-step solutions using entropy scaling and universal weighting. This results in instant convergence, global stability, and deterministic structure across domains—from quantum mechanics to cosmology to optimization theory.

Each variant uses the same universal weighting function—a precomputed entropy-scaled harmonic structure—allowing the system to resolve even traditionally intractable problems such as gravitational wavefunction stability, the Schrödinger equation, or prime factorization, without iterative loops or numerical integration.

This math system underpins multiple other works, including:

The Nature of Constants – deriving 20+ fundamental physical constants from first principles with no empirical input.

Introduction to Q-Epsilon – redefining quantum mechanics as structured energy flow within a resonant vacuum.

Gravitational Field Measurements – offering mass-free gravitational field equations based on energy density.

The Natural Emergence of Physics – demonstrating how Pan reveals the structure behind the constants and equations we’ve taken for granted.

I invite readers not only to explore this document, but to read the broader collection of attached works, which build upon one another to form a complete reimagining of physical law and mathematical structure.

Causal Poisson bracket via deformation quantization

description: Starting with the well-defined product of quantum fields at two spacetime points, we explore an associated Poisson structure for classical field theories within the deformation quantization formalism. We realize that the induced star-product is naturally related to the standard Moyal product through an appropriate causal Green's functions connecting points in the space of classical solutions to the equations of motion. Our results resemble the Peierls-DeWitt bracket analyzed in the multisymplectic context. Once our star-product is defined we are able to apply the Wigner-Weyl map in order to introduce a generalized version of Wick's theorem. Finally, we include some examples to explicitly test our method: the real scalar field, the bosonic string and a physically motivated nonlinear particle model. For the field theoretic models we have encountered causal generalizations of the creation/annihilation relations, and also a causal generalization of the Virasoro algebra for the bosonic string. For the nonlinear particle case, we use the approximate solution in terms of the Green's function in order to construct a well-behaved causal bracket.

SN Hunt 248: a super-Eddington outburst from a massive cool hypergiant

description: We present photometric and spectroscopic observations of SN Hunt 248, a new supernova (SN) impostor in NGC 5806, which began a multi-stage outburst in 2014 May. The initial '2014a' discovery brightening exhibited an absolute magnitude of M~-12 and the spectral characteristics of a cool dense outflow, including P-Cygni lines of Fe II, H I, Na I, and strong line blanketing from metals. The source rapidly climbed and peaked near M~-15 mag after two additional weeks. During this bright '2014b' phase the spectrum became dominated by Balmer emission and a stronger blue continuum, similar to the SN impostor SN 1997bs. Archival images from the Hubble Space Telescope between 1997 and 2005 reveal a luminous (4e5 Lsun) variable precursor star. Its location on the Hertzsprung-Russell diagram is consistent with a massive (M_init~30 Msun) cool hypergiant having an extremely dense wind and an Eddington ratio just below unity. At the onset of the recent 2014a brightening, however, the object became super-Eddington. The subsequent boost in luminosity during the 2014b phase probably resulted from circumstellar interaction. SN Hunt 248 provides the first case of a cool hypergiant undergoing a giant eruption reminiscent of outbursts from luminous blue variable (LBV) stars. This lends support to the hypothesis that some cool hypergiants, such as Rho Cas, could be LBVs masquerading under a pseudo-photosphere created by their extremely dense winds. Moreover, SN Hunt 248 demonstrates that eruptions stemming from such stars can rival in peak luminosity the giant outbursts of much more massive systems like Eta Car.

Disparities in Breast Cancer Treatment and Outcomes: Biological, Social, and Health System Determinants and Opportunities for Research

description: Racial disparities in breast cancer mortality have been widely documented for several decades and persist despite advances in receipt of mammography across racial groups. This persistence leads to questions about the roles of biological, social, and health system determinants of poor outcomes. Cancer outcomes are a function not only of innate biological factors but also of modifiable characteristics of individual behavior and decision making as well as characteristics of patient-health system interaction and the health system itself. Attempts to explain persistent racial disparities have mostly been limited to discussion of differences in insurance coverage, socioeconomic status, tumor stage at diagnosis, comorbidity, and molecular subtype of the tumor. This article summarizes existing literature exploring reasons for racial disparities in breast cancer mortality, with an emphasis on treatment disparities and opportunities for future research. Because breast cancer care requires a high degree of multidisciplinary team collaboration, ensuring that guideline recommended treatment (such as endocrine therapy for hormone receptor positive patients) is received by all racial/ethnic groups is critical and requires coordination across multiple providers and health care settings. Recognition that variation in cancer care quality may be correlated with race (and socioeconomic and health system factors) may assist policy makers in identifying strategies to more equally distribute clinical expertise and health infrastructure across multiple user populations.
