Subjects: Very low mass stars

description: While highly irradiated brown dwarfs are rare, the handful of known systems provide a unique lens into irradiated atmospheres. Ultra-short-period brown dwarfs around white dwarfs can reach atmospheric temperatures hotter than many stars. Such objects are similar to ultra-hot Jupiters, yet are subject to even more intense UV irradiation, allowing us to test irradiated atmosphere models and reveal new insight into substellar atmospheres. We present 1D PHOENIX atmosphere models and synthetic spectra, as well as retrievals with the PETRA framework, of two highly irradiated brown dwarfs around white dwarfs. Crucially, these models self-consistently include the effects of the intense UV irradiation on the atmosphere. We will show that we can explain the observed presence of a variety of emission lines in these brown dwarfs through the an irradiation-induced temperature inversion, not unlike those recently seen in several ultra-hot Jupiters.

description: Die Windkraft stellt eine wichtige Energiequelle in Deutschland dar. Form und Lage der Rotorblätter von Windenergieanlagen haben dabei einen großen Einfluss auf die Effizienz und die Lebensdauer der Anlage. Geometrische Merkmale von Rotorblättern werden mit Blattschablonen, photogrammetrischen oder interferometrischen Messverfahren erfasst. Hierzu muss die Anlage jedoch gestoppt und ggf. mit Mustern bzw. Markern versehen werden. Für In-Prozess-Messungen ohne Manipulation der Windenergieanlage bietet sich das Prinzip der Laufzeitmessung an, auf dem sogenannte terrestrische Laserscanner aufbauen. Bisher unbekannt ist jedoch die erreichbare Messunsicherheit bei der Bestimmung von Pitchwinkeln. In diesem Beitrag werden die Messunsicherheiten bei der Erfassung der Rotorblattoberfläche für Distanzen > 100 m experimentell untersucht und zur Bestimmung der Unsicherheit des Pitchwinkels mittels Monte-Carlo Simulation fortgepflanzt. Für die Betrachtung der Pitchwinkelunsicherheit wird unterschieden, ob die Nenngeometrie der Rotorblätter bekannt ist und absolute Aussagen über die Pitchwinkel getroffen werden können, oder ob die Nenngeometrie unbekannt ist und nur relative Pitchwinkelunterschiede zwischen den Rotorblättern ausgewertet werden können.

description: During the last intrauterine fetal stage of development and the neonatal period the hypothalamic-pituitary-adrenal axis (HPA) is a key system. Apart of cortisol, the adrenals produce dehydroepiandrosterone (DHEA), the major steroid produced by the fetus itself, so that it could be considered as a marker of offspring HPA activity. Non invasive, long time-frame retrospective hormonal levels analysis were performed in the hair of humans and animals, but not in newborn puppies, and DHEA never investigated in puppies. This study was aimed to assess DHEA concentrations in the hair of newborn puppies, and to evaluate the influence of newborn age, gender, and breed size on DHEA concentrations. The study enrolled 116 spontaneously dead puppies, grouped on the base of mother bodyweight to small or medium-large breeds, and on the base of age at death. Hair samples were collected by shaving, and stored at room temperature until RIA analysis. The overall hair DHEA concentrations were 46.8±14.8 pg/mg. DHEA levels were 48.6±15.66 pg/mg in females vs 45.1±13.73 pg/mg in males, without significant differences. DHEA levels were 45.5±13.61 pg/mg in small size puppies and 47.8±15.61 pg/mg in medium-large size puppies, with no significant differences. DHEA concentrations in premature puppies (52.5±15.12 pg/mg) were significant higher (p<0.05) than in puppies dead between 1 and 30 days after birth (44.5±17.78 pg/mg), but similar to fresh term born-dead puppies (46.2±16.5 pg/mg).  This study demonstrated that DHEA is quantifiable in the hair of newborn dogs, and that DHEA levels are significantly influenced by the puppies age.

Very low mass stars

description: Accretion and outflows are key processes in early stellar evolution. The material accreted at the edge of the inner disc is channeled along magnetic funnel flows onto the star. Its kinetic energy is dissipated in standing accretion shocks. The accretion process is therefore sensitive to the spatial and temporal variations of the structure of the magnetic field and its mass load. Due to the change of view of the star-disc system throughout the rotation cycle, geometric effects are superimposed on such intrinsic variability and likely dominate the observed variability. An assessment of changes in the mass accretion rate is essential to understand the structure of the star-disc-magnetosphere system.  The young, very low-mass star Par-Lup3-4 displays a rich emission-line spectrum, hosts a disc with an almost edge-on inclination, and is in the critical mass range near the star/brown dwarf transition, where the knowledge of the accretion/outflow connection remains rather poor. These properties make this star a prime target for conducting a variability study of mass accretion. We make use of X-shooter's unique capabilities to monitor its broad-band spectrum in the range from ultraviolet to near-infrared. The sampling of our ten spectra covers timescales of hours, days, weeks, and years.

description: The coherence function offers new possibilities for optical metrology that are not available with conventional wave field sensing. Its measurement involves a spatio-temporal sampling of the wave fields modulated by the object under investigation. Temporal sampling is well known e. g. by means of White Light Interferometry (WLI) and spatial sampling can e. g. performed by Computational Shear Interferometry (CoSI). The present paper describes an approach that combines both temporal and spatial sampling using a robust common-path setup. While the evaluation of the coherence function is more elaborate than approaches that either sample the temporal or the spatial domain, an information theoretical treatment shows that it also delivers more information about the object under investigation. Our approach is based on the mutual information that represents the reduction of uncertainty about the object as a consequence of the measurements performed. Using a simplified measurement case, we calculate the mutual information for different measurement situations and demonstrate that spatio-temporal sampling of the coherence function results in a higher mutual information as compared to classical approaches. Based on the proposed approach, we identify further open research tasks for an efficient information extraction from the coherence function to surpass current limitations of optical metrology.

description: The demand for scalable measuring systems for the fast measurement of tooth-individual shape parameters of large gears is increasing. Due to a limited measuring speed and a limited measuring volume, standard tactile gear measuring systems are only conditionally suitable for comprehensive measurements of large gears. Therefore, the applicability of a scalable optical multi-distance measurement approach consisting of an optical sensor and a rotary table with a model-based evaluation is studied. As a fundamental gear shape parameter, the base circle radius of a large gearing is evaluated and the achievable measurement uncertainty is estimated. As a result, the tooth-individual base circle radius is determined on average with an expanded measurement uncertainty (k = 2) of one quarter of the required tolerance, and the realized measurement setup enables the measurement of all teeth within 1 minute. Hence, the scalable optical multi-distance measurement approach is appliacable for the fast measurement of tooth-individual shape parameters of large gearings.

description: Red mark syndrome (RMS) is a chronic skin disease of unknown aetiology affecting farmed rainbow trout Oncorhynchus mykiss in Europe that causes single or multiple bright red skin lesions. Histological analysis showed acute inflammation in the area of the skin suggesting a bacterial infection. No aetiological agent has been unequivocally identified, although the involvement of a single transmissible agent has been suggested. The 16S rDNA of a bacterium belonging to the family Midichloriaceae (Rickettsiales) was found in association with RMS skin lesions.
In this work, we present a novel specific method for absolute quantification of the midichloriacea associated with RMS in O. mykiss, based on a quantitative PCR approach. The qPCR method was tested on healthy skin, on lesions when present and on organ samples (heart, liver, spleen, intestine, kidney) from ten fish. Our work shows, for the first time, that the midichloriacea is present not only in skin lesions but also in organs of affected fish. Further studies are needed to prove whether this bacterium is actually involved in the pathology.

Broadcast archives: a diplomatic examination

description: This special diplomatics’ study examines the applicability and usefulness of diploniatics for the analysis of broadcast archives, and specifically, of sound and moving image documents. The traditional model of diplomatic analysis, devised for dispositive and probative documents, was found not applicable to supporting and narrative documents, which constitute most of contemporary archival material. The documents that are characteristic of the broadcast industry in particular are supporting documents; therefore, a new model of diplomatic analysis based on the same principles and methods as the traditional one was developed in this thesis for supporting documents generated by the broadcast industry. The new model was successfully used to analyze textual and non-textual, early and contemporary documents produced by different types and sizes of radio and television stations. The analysis showed that the formation, form, and transmission of supporting documents in the broadcast industry has not changed significantly over time; that, although the organization of every broadcast station is unique and constantly changing, there is a basic organizational structure for all broadcast stations regardless of size; and, that the functions of all stations are basically the same. The analysis also revealed that the model, the scheme, and the procedure of criticism used in this thesis provide an understanding which would assist in appraisal, arrangement, and description of specific broadcast archives. The bottom-up/top-down integrated approach to the analysis supports the understanding of the documentary, administrative and juridical context of the documents in question, and demonstrates that diplomatics can be used to devise new tools for the examination and study of new types of documents. The study concludes that broadcast archives in general, and sound and moving image documents in particular, can be profitably analyzed according to diplomatic principles and methods.
Decoherence in quantum walks - a review

description: The development of quantum walks in the context of quantum computation, as generalisations of random walk techniques, led rapidly to several new quantum algorithms. These all follow unitary quantum evolution, apart from the final measurement. Since logical qubits in a quantum computer must be protected from decoherence by error correction, there is no need to consider decoherence at the level of algorithms. Nonetheless, enlarging the range of quantum dynamics to include non-unitary evolution provides a wider range of possibilities for tuning the properties of quantum walks. For example, small amounts of decoherence in a quantum walk on the line can produce more uniform spreading (a top-hat distribution), without losing the quantum speed up. This paper reviews the work on decoherence, and more generally on non-unitary evolution, in quantum walks and suggests what future questions might prove interesting to pursue in this area.

Nonparametric determination of redshift evolution index of Dark Energy

Publisher: name: arXiv

description: We propose a nonparametric method to determine the sign of γ- the redshift evolution index of dark energy. This is important for distinguishing between positive energy models, a cosmological constant, and what is generally called ghost models. Our method is based on geometrical properties and is more tolerant to uncertainties of other cosmological parameters than fitting methods in what concerns the sign of γ. The same parameterization can also be used for determining $γ$ and its redshift dependence by fitting. We apply this method to SNLS supernovae and to gold sample of re-analyzed supernovae data from Riess et al. 2004. Both datasets show strong indication of a negative γ. If this result is confirmed by more extended and precise data, many of dark energy models, including simple cosmological constant, standard quintessence models without interaction between quintessence scalar field(s) and matter, and scaling models are ruled out.

description: We are concerned with the issue of quantization of a scalar field in a diffeomorphism invariant manner. We apply the method used in Loop Quantum Gravity. It relies on the specific choice of scalar field variables referred to as the polymer variables. The quantization, in our formulation, amounts to introducing the `quantum' polymer *-star algebra and looking for positive linear functionals, called states. Assumed in our paper homeomorphism invariance allows to derive the complete class of the states. They are determined by the homeomorphism invariant states defined on the CW-complex *-algebra. The corresponding GNS representations of the polymer *-algebra and their self-adjoint extensions are derived, the equivalence classes are found and invariant subspaces characterized. In the preceding letter (the part I) we outlined those results. Here, we present the technical details.

description: Co-evolving time series appears in a multitude of applications such as environmental monitoring, financial analysis, and smart transportation. This paper aims to address the following challenges, including (C1) how to incorporate explicit relationship networks of the time series; (C2) how to model the implicit relationship of the temporal dynamics. We propose a novel model called Network of Tensor Time Series, which is comprised of two modules, including Tensor Graph Convolutional Network (TGCN) and Tensor Recurrent Neural Network (TRNN). TGCN tackles the first challenge by generalizing Graph Convolutional Network (GCN) for flat graphs to tensor graphs, which captures the synergy between multiple graphs associated with the tensors. TRNN leverages tensor decomposition to model the implicit relationships among co-evolving time series. The experimental results on five real-world datasets demonstrate the efficacy of the proposed method.

description: Understanding how the magnetic activity of low-mass stars depends on their fundamental parameters is an important goal of stellar astrophysics. Previous studies suggest that the stellar mass and rotation period both play important roles in determining the overall activity level of a star. However, we currently have little information on the role of metallicity. In this poster, we study how magnetic activity scales with stellar metallicity. Specifically, we use photometric variability as a proxy for magnetic activity. Using a sample of over 3000 low-mass stars, we demonstrate that, at fixed stellar mass and rotation, more metal-rich stars are generally more magnetically active.

description: We analyze the alignment of molecules generated by a pair of crossed ultra-short pump pulses of different polarizations by a technique based on the induced time-dependent gratings. Parallel polarizations yield an intensity grating, while perpendicular polarizations induce a polarization grating. We show that both configurations can be interpreted at moderate intensity as an alignment induced by a single polarized pump pulse. The advantage of the perpendicular polarizations is to give a signal of alignment that is free from the plasma contribution. Experiments on femtosecond transient gratings with aligned molecules were performed in CO2 at room temperature in a static cell and at 30 K in a molecular expansion jet.

description: We report measurements of the branching fraction and CP violation parameters in B0 -> D+D- decays. The results are based on a data sample that contains 535 x 10^6 BBbar pairs collected at the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain [1.97 +- 0.20 (stat) +- 0.20 (syst)] x 10^(-4) for the branching fraction of B0 -> D+D-. The measured values of the CP violation parameters are: S = -1.13 +- 0.37 +- 0.09, A = 0.91 +- 0.23 +- 0.06, where the first error is statistical and the second is systematic. We find evidence of CP violation in B0 -> D+D- at the 4.1 sigma confidence level. While the value of S is consistent with expectations from other measurements, the value of the parameter A favors large direct CP violation at the 3.2 sigma confidence level, in contradiction to Standard Model expectations.

description: We study the temporal and spatial dynamics of the large amplitude and frequency modulation that can be induced in an intense, few cycle laser pulse as it propagates through a rapidly ionizing gas. Our calculations include both single atom and macroscopic interactions between the non-linear medium and the laser field. We analyze the harmonic generation by such pulses and show that it is spatially separated from the ionization dynamics which produce a large dynamical blue shift of the laser pulse. This means that small changes in the initial laser focusing conditions can lead to large differences in the laser frequency modulation, even though the generated harmonic spectrum remains essentially unchanged.

description: The number of books published is disproportionate to the number of readers. Thus, there are books widely read and purchased, and books who remain in obscurity. The current study, on the one hand, aims to investigate the way readers choose books for purchase, and how readers talk, both about their choices, as well as the books they reject. On the other hand, the current study canvasses the role of bookstores and booksellers in this book purchase context. This is a qualitative research that follows a phenomenological worldview since the quality and texture of the participant's experiences are analyzed. More specifically, data were collected by using two methods. During the first phase, seven naturalistic observations were conducted at small independent bookshops, big chain bookstores, malls with book department and periodic book events. During the second phase, seven individual semi-structured interviews took place, in which five readers and two booksellers participated. The data analysis systematized and combined both the readers' and the booksellers' ideas and experiences. The results shed light on the reader- bookseller interaction
Discovering the Origin of Yukawa Couplings at the LHC with a Singlet Higgs and Vector-like Quarks

description: Although the 125 GeV Higgs boson discovered at the LHC is often heralded as the origin of mass, it may not in fact be the origin of Yukawa couplings. In alternative models, Yukawa couplings may instead arise from a seesaw type mechanism involving the mixing of Standard Model (SM) chiral fermions with new vector-like fermions, controlled by the vacuum expectation value (VEV) of a new complex Higgs singlet field $\langle Φ\rangle$. For example, the largest third family $(t,b)$ quark Yukawa couplings may be forbidden by a $U(1)'$ gauge or global symmetry, broken by $\langle Φ\rangle$, and generated effectively via mixing with a vector-like fourth family quark doublet $(T,B)$. Such theories predict a new physical Higgs singlet $ϕ$, which we refer to as the Yukon, resulting from $\langle Φ\rangle$, in the same way that the Higgs boson $h^0$ results from $\langle H\rangle$. In a simplified model we discuss the prospects for discovering the Yukon $ϕ$ in gluon-gluon fusion production, with $(t,b)$ and $(T,B)$ quarks in the loops, and decaying in the channels $ϕ\rightarrow γγ, Zγ$ and $ϕ\rightarrow tT\rightarrow tth^0,ttZ$. The potential for discovery of the Yukon $ϕ$ is studied at present or future hadron colliders such as the LHC (Run 3), HL-LHC, HE-LHC and/or FCC. For example, we find that a 300-350 GeV Yukon $ϕ$ could be accessed at LHC Run 3 in the di-photon channel in the global model, providing a smoking gun signature of the origin of Yukawa couplings. The $tth^0,ttZ$ channels are more involved and warrant a more sophisticated analysis.

description: An adiabatic approach put forward by Greiter and Wilczek interpolates between the integer quantum Hall effects of electrons and composite fermions by varying the statistical flux bound to electrons continuously from zero to an even integer number of flux quanta, such that the intermediate states represent anyons in an external magnetic field with the same "effective" integer filling factor. We consider such anyons on a torus, and construct representative wave functions for their ground as well as excited states. These wave functions involve higher Landau levels in general, but can be explicitly projected into the lowest Landau level for many parameters. We calculate the variational energy gap between the first excited state and ground state and find that it remains open as the statistical phase is varied. Finally, we obtain from these wave functions, both analytically and numerically, various topological quantities, such as ground-state degeneracy, the Chern number, and the Hall viscosity.

description: We explore the observational appearance of the photosphere of an ultrarelativistic flow with internal dissipation of energy as predicted by the magnetic reconnection model. Previous study of the radiative transfer in the photospheric region has shown that gradual dissipation of energy results in a hot photosphere. There, inverse Compton scattering of the thermal radiation advected with the flow leads to powerful photospheric emission with spectral properties close to those of the observed prompt GRB emission. Here, we build on that study by calculating the spectra for a large range of the characteristics of the flow. An accurate fitting formula is given that provides the photospheric spectral energy distribution in the ~10 keV to ~10 MeV energy range (in the central engine frame) as a function of the basic physical parameters of the flow. It facilitates the direct comparison of the model predictions with observations, including the variability properties of the lightcurves. We verify that the model naturally accounts for the observed clustering in peak energies of the E*f(E) spectrum. In this model, the Amati relation indicates a tendency for the most luminous bursts to have more energy per baryon. If this tendency also holds for individual GRB pulses, the model predicts the observed narrowing of the width of pulses with increasing photon energy.

description: Semiconductor nanowires exhibit large polarization anisotropy for the absorption and emission of light, making them ideal building blocks for novel photonic metamaterials. Here, we demonstrate that a high density of aligned nanowires exhibits giant optical birefringence, a collective phenomenon observable uniquely for collections of wires. The nanowire material was grown on gallium phosphide (GaP) (111) in the form of vertically standing GaP nanowires. We obtain the largest optical birefringence to date, with a difference between the in-plane and out-of-plane refractive indices of 0.80 and a relative birefringence of 43%. These values exceed by a factor of 75 the natural birefringence of quartz and a by more than a factor of two the highest values reported so far in other artificial materials. By exploiting the specific crystallographic growth directions of the nanowires on the substrate, we further demonstrate full control over the orientation of the optical birefringence effect in the metamaterial.

description: The primitive model of ionic systems is investigated within a field-theoretic description for the whole range of size-, λ, and charge, Z, ratios of the two ionic species. Two order parameters (OP) are identified, and their relations to physically relevant quantities are described for various values of λand Z. Instabilities of the disordered phase associated with the two OP's are determined in the mean-field approximation. A gas-liquid separation occurs for any Z and λdifferent from 1. In addition, an instability with respect to various types of periodic ordering of the two kinds of ions is found.

Making the new museology work
Creators: name: Hise, Beth
Publisher: name: University of British Columbia
Year: 2009

description: Australian museums, encouraged to promote the value of cultural diversity by Australian government mulitculturalism policies and the many critics calling for change in museums, are re evaluating many of their cultural programs and introducing new initiatives. They are implementing community participation schemes, improving access to their collections and programs and becoming more responsive to the needs, demands and desires of their constituencies. But are these new programs and changes in museums really meeting the lofty objectives of fostering equality and promoting the benefits of diversity? This thesis will analyse the impact and potential long-term effects of community-oriented museum programs and access strategies by focusing on the interaction between policy and practice in exhibition development at the Australian Museum, a large museum in Sydney devoted to the natural environment and cultural heritage of Australia. A case study of two cultural exhibitions and their development reveals the problematic nature of museum and “community” relationships and the wide gulf that exists between exhibition objectives and their final outcome.
3D-2D analysis of a thin film with periodic microstructure

China's Repression of the Xinjiang Uyghur: Ethnic Conflict in Xinjiang, China and the Application of John Burton's Human Needs Theory

description: This thesis is focused on the analysis of the conflict between the Uyghurs and the Chinese government in Xinjiang, China using John Burton’s Human Needs Theory. Xinjiang or the Xinjiang Uyghur Autonomous Region (XUAR) is a province in China’s northwestern corner. It is a predominantly Muslim province, inhabited by the Uyghur population. Ethnic conflict and unrest plague the province. The Chinese government has designated separatism and terrorism in the region as one of the nation’s largest security challenges. According to the Chinese government, the conflict in Xinjiang threatens the social fabric and stability in Xinjiang and the country as a whole. In response to this security challenge, the Chinese government has adopted a policy of striking hard, whereby they employ methods to reduce extremism, and religious and ethnic terrorism. These approaches have been accused of being militarized, securitized, and embedded with religious and ethnic repression and discrimination which threaten the human rights and human needs of the Uyghur population. This thesis aims to describe and outline these occurrences and the general climate of marginalization in Xinjiang. This thesis aims to demonstrate that this repression deprives the Uyghur population of their fundamental human needs and increases a sense of hopelessness and desperation. This exacerbates tensions in the region and leads to a rise in violence and terrorism. In this way, this thesis will use John Burton’s Human Needs Theory to demonstrate and explore how the policies adopted by the Chinese government may not only be ineffective, but also counterproductive, in tackling the region’s security challenges. It will focus on the intersections between repression, counterterrorism, and John Burton’s Human Needs Theory. It aims to present a case study that offers an understanding of how the Chinese government’s policies may be further threatening national security and stability and demonstrates the implications of certain counterterror policies aimed towards religious and ethnic terrorism. Ultimately, it aims to show that structural violence and the deprivation of human needs must be tackled for conflict resolution to occur.
The discovery of superfluidity

description: Superfluidity is a remarkable manifestation of quantum mechanics at the macroscopic level. This article describes the history of its discovery, which took place at a particularly difficult period of the twentieth century. A special emphasis is given to the role of J.F. Allen, D. Misener, P. Kapitza, F. London, L. Tisza and L.D. Landau. The nature and the importance of their respective contributions are analyzed and compared. Of particular interest is the controversy between Landau on one side, London and Tisza on the other, concerning the relevance of Bose-Einstein condensation to the whole issue, and also on the nature of thermal excitations in superfluid helium 4. In order to aid my understanding of this period, I have collected several testimonies which inform us about the work and attitude of these great scientists.

description: The paper deals with the asymptotic behavior of the bridge of a Gaussian process conditioned to stay in $n$ fixed points at $n$ fixed past instants. In particular, functional large deviation results are stated for small time. Several examples are considered: integrated or not fractional Brownian motion, $m$-fold integrated Brownian motion. As an application, the asymptotic behavior of the exit probability is studied and used for the practical purpose of the numerical computation, via Monte Carlo methods, of the hitting probability up to a given time.

description: The general formalism for the description of neutrino oscillations in arbitrary rapidly varying external fields is elaborated. We obtain the new effective Hamiltonian which determines the evolution of the averaged neutrino wave function. The general technique is applied to the neutrino oscillations in rapidly varying magnetic fields. We evaluate the transition probabilities of the neutrino spin-flavor oscillations in magnetic fields of the Sun and compare them with the numerical solutions of the Schroedinger equation with the exact Hamiltonian.
