description: We present a systematic search for changing-look quasars based on repeat photometry from SDSS and Pan-STARRS1, along with repeat spectra from SDSS and SDSS-III BOSS. Objects with large, |Δg|>1 mag photometric variations in their light curves are selected as candidates to look for changes in broad emission line (BEL) features. Out of a sample of 1011 objects that satisfy our selection criteria and have more than one epoch of spectroscopy, we find 10 examples of quasars that have variable and/or "changing-look" BEL features. Four of our objects have emerging BELs; five have disappearing BELs, and one object shows tentative evidence for having both emerging and disappearing BELs. With redshifts in the range 0.20 < z < 0.63, this sample includes the highest-redshift changing-look quasars discovered to date. We highlight the quasar J102152.34+464515.6 at z = 0.204. Here, not only have the Balmer emission lines strongly diminished in prominence, including H$β$ all but disappearing, but the blue continuum $f_ν \propto ν^{1/3}$ typical of an AGN is also significantly diminished in the second epoch of spectroscopy. Using our selection criteria, we estimate that >15% of strongly variable luminous quasars display changing-look BEL features on rest-frame timescales of 8 to 10 years. Plausible timescales for variable dust extinction are factors of 2-10 too long to explain the dimming and brightening in these sources, and simple dust reddening models cannot reproduce the BEL changes. On the other hand, an advancement such as disk reprocessing is needed if the observed variations are due to accretion rate changes.

description: Introduction: Understanding Colonial Tribal Knowledge
 To study 'tribes' is to be drawn into the world of colonial knowledge. As I take up the Ho tribe of Chotanagpurl and reconstruct the process of its social stratification, I have mainly to grapple with what is known as British ethnography. The question naturally how dependable this ethnography is when we study Ho life.
 British ethnography is part of the discourse commonly known as Orientalism. But one has to understand that, even in their oneness, Indian Orientalism and 'tribal Orientalism' had a major difference. When Indian Orientalism was recreated, scholars at the Asiatic of Bengal could draw upon literate and archaeological sources. But when it came to dealing with tribal society, British administrator ethnographers as well as Indian scholars were forced to make do with oral traditions and their observations of lived reality as their main sources of information. This information was saturated by ideologically-structured tribal epistemology.

description: Information retrieval services can be difficult to evaluate because relevance is difficult to define, much less quantify. Mean Average Precision , a measure popularized by the Text Retrieval Conferences of the past dozen-plus years, on relevance measures defined by recall and precision, but omits valuable information about system performance in its averaging of individual topic precision. A measure is needed, especially in the corporate context, where pressure to optimize enterprise search system performance is heavy - the real challenge is finding the best one. This paper analyzes the use of a variation of Mean Average Precision and evaluates its appropriateness as a metric for measuring the success rate of at SomaPharm, Inc., a pharmaceutical company's enterprise (intranet) search service. The results indicate that the current metric worked well for some topics, but that the averaging properties and the threshold component were not as effective for other topics, and did not adequately represent users' needs.

description: The inner regions of the most massive compact stellar objects might be occupied by a phase of quarks. Since the observations of the massive pulsars PSR J1614-2230 and of PSR J0348+0432 with about two solar masses, the equations of state constructing relativistic stellar models have to be constrained respecting these new limits. We discuss stable hybrid stars, i.e. compact objects with an outer layer composed of nuclear matter and with a core consisting of quark matter (QM). For the outer nuclear layer we utilize a density dependent nuclear equation of state and we use a chiral SU(3) Quark-Meson model with a vacuum energy pressure to describe the objects core. The appearance of a disconnected mass-radius branch emerging from the hybrid star branch implies the existence of a third family of compact stars, so called twin stars. Twin stars did not emerge as the transition pressure has to be relatively small with a large jump in energy density, which could not be satisfied within our approach. This is, among other reasons, due to the fact that the speed of sound in QM has to be relatively high, which can be accomplished by an increase of the repulsive coupling. This increase on the other hand yields too high transition pressures for twins stars to appear.

Bose-Einstein condensation and critical behavior of two-component bosonic gases

description: We study Bose-Einstein condensation (BEC) in three-dimensional two-component bosonic gases, characterizing the universal behaviors of the critical modes arising at the BEC transitions. For this purpose, we use field-theoretical (FT) renormalization-group (RG) methods and perform mean-field and numerical calculations. The FT RG analysis is based on the Landau-Ginzburg-Wilson Phi4 theory with two complex scalar fields which has the same symmetry as the bosonic system. In particular, for identical bosons with exchange Z_2,e symmetry, coupled by effective density-density interactions, the global symmetry is Z_2e X U(1) X U(1). At the BEC transition it may break into Z_2,e X Z_2 X Z_2 when both components condense simultaneously, or to U(1) X Z_2 when only one component condenses. This implies different universality classes for the corresponding critical behaviors. Numerical simulations of the two-component Bose-Hubbard model in the hard-core limit support the RG prediction: when both components condense simultaneously, the critical behavior is controlled by a decoupled XY fixed point, with unusual slowly-decaying scaling corrections arising from the on-site inter-species interaction.

description: The coupling between the electromagnetic and gravitational fields results in "faster than light" photons and invalids the Lorentz invariance and some laws of physics. A typical example is that the first and third laws of geometric optics are invalid in the usual spacetime. By introducing an effective spacetime, we find that the wave vector can be casted into null and then it obeys the geodesic equation, the polarization vector is perpendicular to the rays, and the number of photons is conserved. That is to say, the laws of geometric optics are still valid for the modified theory in the effective spacetime. We also show that the focusing theorem of light rays for the modified theory in the effective spacetime takes the same form as usual.

description: A recent debate has ensued over the claim by Pikovski et al. [Nat. Phys. 11, 668 (2015)] that systems with internal degrees of freedom undergo a universal, gravity-induced, type of decoherence that explains their quantum-to-classical transition. This decoherence is supposed to arise from the different gravitational redshifts experienced by such systems when placed in a superposition of two wave packets at different heights in a gravitational field. Here we investigate some aspects of the discussion with the aid of simple examples. In particular, we first resolve an apparent conflict between the reported results and the equivalence principle by noting that the static and free-fall descriptions focus on states associated with different hypersurfaces. Next, we emphasize that predictions regarding the observability of interference become relevant only in the context of concrete experimental settings. As a result, we caution against hasty claims of universal validity. Finally, we dispute the claim that, at least in the scenarios discussed by Pikovski et al., gravitation is responsible for the reported results, and we question the alleged ability of decoherence to explain the quantum-to-classical transition. In consequence, we argue against the extraordinary assertion by Pikovski et al. that gravity can account for the emergence of classicality.

description: The enrichment in s-process elements of barium stars is known to be due to pollution by mass transfer from a companion formerly on the thermally-pulsing asymptotic giant branch (AGB), now a carbon-oxygen white-dwarf (WD). This paper investigates the relationship between the s-process enrichment in the barium star and the mass of its WD companion. It is expected that helium WDs, which have masses smaller than about 0.5 Msun and never reached the AGB phase, should not pollute with s-process elements their giant companion, which should thus never turn into a barium star. Spectra with a resolution of R ~ 86000 were obtained with the HERMES spectrograph on the 1.2-m Mercator telescope for a sample of 11 binary systems involving WD companions of various masses. We use standard 1D LTE MARCS model atmospheres coupled with the Turbospectrum radiative-transfer code to derive the atmospheric parameters using equivalent widths of FeI and Fe II lines. The abundances of s-process elements for the entire sample of 11 binary stars were derived homogeneously. The sample encompasses all levels of overabundances: from solar [s/Fe]=0 to 1.5 dex in the 2 binary systems with S-star primaries (for which dedicated MARCS model atmospheres were used). The primary components of binary systems with a WD more massive than 0.5 Msun are enriched in s-process elements. We also found a trend of increasing [s/Fe] with [C/Fe] or [(C+N)/Fe]. Our results conform to the expectation that binary systems with WD companions less massive than 0.5 Msun do not host barium stars.

description: We designed and demonstrate a fiber-based amplified spontaneous emission (ASE) source with low spatial coherence, low temporal coherence, and high power per mode. ASE is produced by optically pumping a large gain core multimode fiber while minimizing optical feedback to avoid lasing. The fiber ASE source provides 270 mW of continuous wave emission, centered at λ=1055 nm with a full-width half-maximum bandwidth of 74 nm. The emission is distributed among as many as ~70 spatial modes, enabling efficient speckle suppression when combined with spectral compounding. Finally, we demonstrate speckle-free full field imaging using the fiber ASE source. The fiber ASE source provides a unique combination of high power per mode with both low spatial and low temporal coherence, making it an ideal source for full-field imaging and ranging applications.

description: We study the chiral separation and chiral magnetic effects in a slab of Dirac semimetal of finite thickness, placed in a constant magnetic field perpendicular to its surfaces. We utilize the Bogolyubov boundary conditions with a large Dirac mass (band gap) outside the slab. We find that, in a finite thickness slab, the axial current density is induced by helicity-correlated standing waves and, as a consequence, is quantized. The quantization is seen in its stepped-shape dependence on the fermion chemical potential and a sawtooth-shape dependence on the thickness of the slab. In contrast to a naive expectation, there is no chiral charge accumulation anywhere in the bulk or at the boundaries of the semimetal. In the same slab geometry, we also find that a nonzero chiral chemical potential induces no electric current, as might have been expected from the chiral magnetic effect. We argue that this outcome is natural and points to the truly non-static nature of the latter. By taking into account a nonzero electric field of a double layer near the boundaries of the slab, we find that the low-energy modes under consideration satisfy the continuity equation for axial current density without the anomalous term.

description: In recent years, an emerging strand of research has focused on the role arrival neighbourhoods play for newcomers finding their footing in a new urban context. However, little is known about the underlying factors and drivers influencing their function(ing). This concerns in particular the role of the local housing market and its players in shaping their emergence and development. The paper deals with the question of how arrival neighbourhoods are (co-)produced by housing market players and how the latter are embedded in local governance structures. Looking at three German arrival neighbourhoods, the article illustrates how they are co-produced by ownership structures and the allocation practices of different housing market players. However, the strengthening of an arrival neighbourhood´s function not only depends on ownership structures but also on the capacities of municipal housing providers and civil society organisations, their strategic goals and the will for (concerted) action. Our findings show that arrival neighbourhoods can take on an important citywide function, enabling newcomers to gain a foothold in the city if three criteria are met: they are accessible/affordable for low-income groups, are equipped with infrastructures for newcomers, and are permeable with regard to residents’ relocation to other neighbourhoods.

description: Four saliva probes were collected per day from 104 children (10 to 35 months old) transitioning from home (T0) to childcare across a four-month period (until T3), resulting in over one thousand cortisol values. Latent Profile Analysis classified three profiles within a regular spectrum of children’s cortisol rhythms and described a fourth hypocortisol stress profile. Further Latent Transition Analysis revealed that profiles frequently changed across the transition but stabilized at T3. Most importantly, regular profiles across transition most likely occurred with high AQS scores of mother-child and care provider–child attachment. A machine learning procedure (XGBoost) featured predictors for stress profiles at T3 (when the child ought to be adjusted and stress profiles should be rare) referring to characteristics of the children (e.g., gender, number of siblings, peer contact before entry), the mothers (their worries), the care providers (their work experience, engagement, attachment) and the groups in the childcare centers (e.g., size, age differences, illness frequency). As a result, experience with siblings and peers before entry facilitated the transition. However, most conditions not linearly affecting children’s cortisol revealed even opposite effects when analyzed at different times. For example, smaller group size and large age-differences at T1 helped the child to stabilize a Regular profile, perhaps due to better control over the situation and greater support from the older children in the group. At T3, however, Regular profiles were associated with larger group size and smaller age-differences which might be helpful for establishing close peer relationships to buffer stress.

description: We explore the range of probabilistic behaviours that can be engineered with Chemical Reaction Networks (CRNs). We show that at steady state CRNs are able to "program" any distribution with finite support in $\mathbb{N}^m$, with $m \geq 1$. Moreover, any distribution with countable infinite support can be approximated with arbitrarily small error under the $L^1$ norm. We also give optimized schemes for special distributions, including the uniform distribution. Finally, we formulate a calculus to compute on distributions that is complete for finite support distributions, and can be compiled to a restricted class of CRNs that at steady state realize those distributions.

description: Prior research has suggested three explanations why levels of voluntary engagement rise and fall over time within societies. A social structural explanation considers individual resources crucial for engagement and argues that a redistribution of those resources may bring about changes in engagement. A cohort-based explanation considers socialisation and experiences in formative years as crucial for the uptake of engagement. Finally, a period-based explanation considers extraordinary events, external shocks, and crises to be crucial for engagement. So far, these explanations have mainly been tested separately and little is known about the relative strength of each of the proposed factors. Using data from a large German household panel survey that assessed engagement almost annually across four decades, we found that most social structural factors (e.g., education, employment, income) maintained their predictive effects for engagement, irrespective of cohort or period. The only notable exception was that the gender gap observed has narrowed substantially across periods and cohorts. Moreover, cohort effects were rendered almost negligible once we factored in periods. Taken together, our results suggest that individual characteristics and extraordinary events are the main factors influencing voluntary engagement rather than shared societal experiences of cohorts.

description: While a review of the literature reveals a set of accepted standards for quality teen space  design, this paper seeks to determine if public library teen spaces currently succeed in  meeting these standards. Teen space design is significant not only for its aesthetic value,  but for its impact on teens, who face many developmental challenges as well as a lack of  safe and welcoming environments in which to experience them. Library teen spaces were  examined both in theory and in practice, comparing the standards portrayed through  available literature to reality. An extensive literature review was conducted, and a  compendium of recommendations was used to establish a set of accepted standards. A  selection of public library teen spaces was then evaluated to determine their adherence to  these standards. Gaps in service were analyzed, and, finally, changes to improve service  to the teen population were recommended.

description: The key objective of this thesis was to appraise the Building Information Modelling (BIM) in Tanzania. The thesis has shown that in Tanzania Building Information Modeling (BIM) can be used to improve Bills of Quantities (BOQ) productivity in the public construction project delivery. The thesis key contribution is the proposed fundamentals in developing a country specific BIM model. Equally, the study has given a more specific definition of Building Information Modeling (BIM) and shown the existing relationship of BIM and Bills of Quantities in improving performance construction projects delivery in Tanzania. This study, designed the hypothesis approach to describe the association between Building Information Modeling (BIM) and Bills of Quantities (BOQ), which facilitated the development of an economical and technologically simple BIM model parameters for Tanzania. Although the relationship found was insignificant, the developed 5DBIMBOQ model is expected to be more productive in the Total Cost Management (TCM) and hence improve information integration in the construction project deliveries in Tanzania. Further areas of study should include the empirical testing of hypothesis in order to further measure the behaviour of other key parameters like collaboration in order to develop the Tanzanian BIM Model.

In this paper it is shown that the same holds true when one uses the short-step, primal interior point method. The main idea of the proof is to employ Diophantine approximation at each iteration to bound the intermediate bit-sizes of iterates.

A sample of 1,181 university students in Germany (762 female) were randomly assigned to an intervention and a no-intervention control group. The intervention group completed six modules addressing established antecedents of sexual aggression perpetration and victimization: risky sexual scripts, risky sexual behavior, low sexual self-esteem, low sexual assertiveness, acceptance of sexual coercion, and perceived realism of pornography. After baseline (T1), intervention effects were measured one week after the last module (T2), nine months later (T3), and another 12 months later (T4). The intervention group showed significantly less risky sexual scripts and higher sexual self-esteem at T2, T3, and T4. The intervention indirectly reduced risky sexual behavior at T3 and T4 via less risky sexual scripts at T2 and increased sexual assertiveness at T3 and T4 via higher sexual self-esteem at T2. No intervention effects were found on the acceptance of sexual coercion and pornography realism. The implications of the findings for reducing the prevalence of sexual aggression perpetration and victimization are discussed.

description: Electrical stimulation of retinal ganglion cells (RGC) plays an important role in the creation of retinal prostheses which aim to restore vision in people suffering from degenerative retinal diseases by stimulating the remaining healthy retinal neurons. In order to better investigate the influence of electrical stimulation on RGCs, in addition to experimental studies, many computational RGC models have been developed. Given that most of these models are based on the deterministic well-known Hodgkin and Huxley model, they also lack a stochastic component that would mimic the natural channel noise present in cells. When we calculate the stimulus threshold with a deterministic model, we lose information about the spiking probability, which increases from 0 to 1 as a function of stimulus intensity following thereby the shape of a sigmoidal curve. In this thesis we study the stochastic behavior of RGCs by calculating dynamic range (DR), defined as the stimulus intensity range in which spiking probability increases from 0.1 to 0.9. The main aim of the thesis is to analyze DR in dependency on the stimulated part of the RGC, since different cell sections show different geometrical and biophysical properties. For that, a multi-compartment RGC model based on Fohlmeister and Miller model from 1997 was implemented in NEURON and Python. A stochastic component was added to the model by injecting the maximum sodium conductance dependent noise current into each cell compartment. We observed that, regardless of the type of stimulation (intracellular or extracellular), DR values given as percentage seem to show a somewhat inverse relationship to threshold values. With intracellular stimulation, a steeper sigmoidal curve of spiking probability was observed for axonal than for somatic compartments, as reported by previous experimental studies. With extracellular stimulation this behavior was observed only after increasing channel noise at soma. While estimating DR with an upper threshold, similar DR values given in μA (not normalized to threshold) as with a lower threshold were observed, which could indicate from previous studies reported characteristic U-shape of spiking probability as a function of stimulus intensity.

description: This work explores a simple model of a slender, flexible structure in a uniform flow, providing analytical solutions for the translating, axially flowing equilibria of strings subjected to a uniform body force and drag forces linear in the velocities. The classical catenaries are extended to a five-parameter family of curves. A sixth parameter affects the tension in the curves. Generic configurations are planar, represented by a single first order equation for the tangential angle. The effects of varying parameters on representative shapes, orbits in angle-curvature space, and stress distributions are shown. As limiting cases, the solutions include configurations corresponding to "lariat chains" and the towing, reeling, and sedimentation of flexible cables in a highly viscous fluid. Regions of parameter space corresponding to infinitely long, semi-infinite, and finite length curves are delineated. Almost all curves subtend an angle less than $π$ radians, but curious special cases with doubled or infinite range occur on the borders between regions. Separate transitions in the tension behavior, and counterintuitive results regarding finite towing tensions for infinitely long cables, are presented. Several physically inspired boundary value problems are solved and discussed.

Wigner crystallization at graphene edges

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Using many-body configuration interaction techniques we show that Wigner crystallization occurs at the zigzag edges of graphene at surprisingly high electronic densities up to $0.8$ $\mbox{nm}^{-1}$. In contrast with one-dimensional electron gas, the flat-band structure of the edge states makes the system interaction dominated, facilitating the electronic localization. The resulting Wigner crystal manifests itself in pair-correlation functions, and evolves smoothly as the edge electron density is lowered. We also show that the crystallization affects the magnetization of the edges. While the edges are fully polarized when the system is charge neutral (i.e. high density), above the critical density, the spin-spin correlations between neighboring electrons go through a smooth transition from antiferromagnetic to magnetic coupling as the electronic density is lowered.

description: Caucasia is a global biodiversity hotspot, rich in amphibians, including several endemic species. We sequenced samples from Parsley frogs (genus Pelodytes) across their Anatolian range to generate a barcode reference database and to assess patterns of genetic diversity in the species. Different species delimitation methods (ABGD, ASAP, GMYC and PTP) were applied to assess species diversity in the genus Pelodytes based on published and newly obtained mtDNA sequences. A majority of the species delimitation tests (ABGD, GMYC and ASAP) recovered four taxonomic units corresponding to currently accepted taxonomy (P. atlanticus, P. caucasicus, P. ibericus and P. punctatus). PTP, on the other hand, recovered only two taxonomic units, one combining the three Iberian taxa (P. atlanticus, P. ibericus, and P. punctatus), and the other, P. caucasicus. In Anatolia, individuals from Giresun and Trabzon were found to be genetically closer to each other compared to those from Rize and Artvin, based on genetic distances and phylogenetic and haplotype network analyses.

description: Citizens in modern democracies have a continuously expanding set of tools at their disposal through which they seek to exercise influence on politics, including digital modes of participation. However, the usage of these tools is still gendered to the disadvantage of women. Feminist attitudes have been shown to have a positive impact on women’s political participation, yet this effect is deeply interwoven with the empowering effect of a feminist identity. Based on an online survey of more than 300 German female Internet users self-labeling as feminists, we develop a comprehensive measure of a feminist identity and analyze the interplay of three distinct sets of feminist attitudes and a feminist identity on online political participation. To gain a fine-grained understanding of the impact of feminist cognitions on online political participation, we differentiate general political online behaviors from those geared toward women’s rights and feminist objectives. We find a feminist identity to be a strong predictor of both types of online political participation, with a stronger effect on feminist online participation. Our findings provide important insights into the empowering role of a feminist identity on women’s political behavior on the Internet.

description: We present a method for the enumeration of restricted words over a finite alphabet. Restrictions are described through the inclusion or exclusion of suitable building blocks used to construct the words by concatenation. Our approach, which relies on the invert transform and its representation in terms of partial Bell polynomials, allows us to generalize and address in a systematic manner previous results in the subject.

description: Planetary rotation rates and obliquities provide information regarding the history of planet formation, but have not yet been measured for evolved extrasolar planets. Here we investigate the theoretical and observational perspective of the Rossiter-McLauglin effect during secondary eclipse (RMse) ingress and egress for transiting exoplanets. Near secondary eclipse, when the planet passes behind the parent star, the star sequentially obscures light from the approaching and receding parts of the rotating planetary surface. The temporal block of light emerging from the approaching (blue-shifted) or receding (red-shifted) parts of the planet causes a temporal distortion in the planet's spectral line profiles resulting in an anomaly in the planet's radial velocity curve. We demonstrate that the shape and the ratio of the ingress-to-egress radial velocity amplitudes depends on the planetary rotational rate, axial tilt and impact factor (i.e. sky-projected planet spin-orbital alignment). In addition, line asymmetries originating from different layers in the atmosphere of the planet could provide information regarding zonal atmospheric winds and constraints on the hot spot shape for giant irradiated exoplanets. The effect is expected to be most-pronounced at near-infrared wavelengths, where the planet-to-star contrasts are large. We create synthetic near-infrared, high-dispersion spectroscopic data and demonstrate how the sky-projected spin axis orientation and equatorial velocity of the planet can be estimated. We conclude that the RMse effect could be a powerful method to measure exoplanet spins.
