Production of the public voice : public participation in the hearing process as contemporary democracy
Creators: name: Hessing, Melody Beatrice
Publisher: name: University of British Columbia
Year: 2010

description: The dissertation examines public participation in the hearing process from the perspective of democratic theory. Although "democracy" is popularly invoked as both rationale and evaluative standard for public participation, political theorists have neglected to examine the practice of hearing intervention from this perspective. The dissertation challenges the pluralist model of the hearing using a participatory critique of the hearing process. The dissertation argues that contemporary discussion of public participation is formulated from the perspective of pluralist democratic theory. Pluralist theory perceives the hearing as a forum through which public access to the administrative and policy-making processes can be secured. Central characteristics of the hearing process, from this perspective, include a heterogeneity of participating interests (which includes the public), a fairness of procedures, and a neutrality of decision-making. In contrast, a participatory critique of pluralist theory points to a restricted public participation, a systematic imbalance in resources available to tribunal participants, and an advantage to and alliance among state and entrepreneurial interests as features of the tribunal. The dissertation studies public hearings in two tribunals: the Pesticide Control Appeal Board, and the Royal Commission of Inquiry into Uranium Mining. The first is an administrative tribunal which hears appeals concerning the approval of pesticide applications. In the second, a consultative tribunal, hearings are held for the purposes of receiving information and making recommendations about uranium mining in British Columbia. The methodology includes observation, ethnography, interviewing, and documentary analysis of the public hearing process. The dissertation finds that the practice of the public hearing is generated from and generally consistent with a pluralist democratic perspective: multiple interests participate; quasi-judicial procedures are followed by all participants, and decisions are made by heterogeneous, government-appointed Boards. A participatory critique however shows the dominance of the pluralist model of hearings to be predicated on a social and economic organization in which social inequality and state hegemony are primary features. Accordingly, systematic social inequalities such as differential access to hearing resources disadvantage public interest groups and preclude a balance among competing forces within the tribunal. Structural and professional alliances among administrative and entrepreneurial forces further detract from the impartiality of the hearing. Countering the pluralist notion of the tribunal as an independent forum, this analysis points to the hearing as a vehicle of social control and state legitimation. The dissertation concludes with recommendations for the democratization of the public hearing.

description: We reconsider the thermodynamics of AdS black holes in the context of gauge-gravity duality. In this new setting where both the cosmological constant $Λ$ and the gravitational Newton constant $G$ are varied in the bulk, we rewrite the first law in a new form containing both $Λ$ (associated with thermodynamic pressure) and the central charge $C$ of the dual CFT theory and their conjugate variables. We obtain a novel thermodynamic volume, in turn leading to a new understanding of the Van der Waals behavior of the charged AdS black holes, in which phase changes are governed by the degrees of freedom in the CFT. Compared to the "old" $P-V$ criticality, this new criticality is "universal" (independent of the bulk pressure) and directly relates to the thermodynamics of the dual field theory and its central charge.

Space, place and atmosphere. Emotion and peripherical perception in architectural experience
Creators: name: Pallasmaa, Juhani
Publisher: name: Lebenswelt. Aesthetics and philosophy of experience.
Year: 2014

description: Architectural experiences are essentially multi-sensory and simultaneous, and a complex entity is usually grasped as an atmosphere, ambience or feeling. In fact, the judgement concerning the character of a space or place calls for categories of sensing that extend beyond the five Aristotelian senses, such as the embodied existential sense, and, as a result, the entity is perceived in a diffuse, peripheral and unconscious manner. Paradoxically, we grasp an atmosphere before we have consciously identified its constituent factors and ingredients. «We perceive atmospheres through our emotional sensibility – a form of perception that works incredibly quickly, and which we humans evidently need to help us survive», Peter Zumthor suggests. We are mentally and emotionally affected by works of art before we understand them, or we may not understand them intellectually at all. Sensitive artists and architects intuit experiential and emotive qualities of spaces, places and images. This capacity calls for a specific kind of imagination, an emphatic imagination. Atmospheres are percieved peripherally through diffuse vision interacting with other sense modalities, and they are experienced emotionally rather than intellectually. The studies on the differentiation of the two brain hemispheres suggest that atmospheres are perceived through the right hemisphere. Somewhat surprisingly, atmospheres are more conscious objectives in literature, cinema, theater, painting and music than in architecture, which has been traditionally approached formally and perceived primarily through focused vision. Yet, when we see a thing in focus, we are outsiders to it, whereas the experience of being in a space calls for peripheral and unfocused perception. One of the reasons for the experiential poverty of contemporary settings could be in the poverty of their peripheral stimuli.

description: We consider the decoherence of photons suffering in phase-damping channels. By exploring the evolutions of single-photon polarization states and two-photon polarization-entangled states, we find that different frequency spectrum envelopes of photons induce different decoherence processes. A white frequency spectrum can lead the decoherence to an ideal Markovian process. Some color frequency spectrums can induce asymptotical decoherence, while, some other color frequency spectrums can make coherence vanish periodically with variable revival amplitudes. These behaviors result from the non-Markovian effects on the decoherence process, which may give rise to a revival of coherence after complete decoherence.

description: M. Kruskal showed that each nearly-periodic dynamical system admits a formal $U(1)$ symmetry, generated by the so-called roto-rate. We prove that such systems also admit nearly-invariant manifolds of each order, near which rapid oscillations are suppressed. We study the nonlinear normal stability of these slow manifolds for nearly-periodic Hamiltonian systems on barely symplectic manifolds -- manifolds equipped with closed, non-degenerate $2$-forms that may be degenerate to leading order. In particular, we establish a sufficient condition for long-term normal stability based on second derivatives of the well-known adiabatic invariant. We use these results to investigate the problem of embedding guiding center dynamics of a magnetized charged particle as a slow manifold in a nearly-periodic system. We prove that one previous embedding, and two new embeddings enjoy long-term normal stability, and thereby strengthen the theoretical justification for these models.

We show that $Y$ has a multiplicative Chow-Künneth decomposition, in the sense of Shen-Vial. As a consequence, the Chow ring of (powers of) $Y$ displays K3-like behaviour. As a by-product of the argument, we also establish a multiplicative Chow-Künneth decomposition for the resolution of singularities of a general nodal cubic hypersurface of even dimension.

Urban ambiances as common ground?
Creators: name: Thibaud, Jean-Paul
Publisher: name: Lebenswelt. Aesthetics and philosophy of experience.
Year: 2014

description: The aim of this paper is to point out various arguments which question ambiance as a common ground of everyday urban experience. Such a project involves four major points. First, we have to move beyond the exclusive practical aspects of everyday life and bring the sensory to the forefront. Under such conditions, sensory cultures emerge where feeling and acting come together. Second, we must put common experience into perspectiveby initiating a dual dynamics of socialising the sensory and sensitising social life. Ambiances involve a complex web comprised of an ‘existential’ dimension (empathy with the ambient world), a ‘contextual’ dimension (degree of presence in the situation), and an ‘interactional’ dimension (forms of sociability expressed in the tonality). Third, we have to initiate a political ecology of ambiances in order to better understand how ambiances deal with fundamental design and planning issues. Far from being neutral, the notion of ambiance appears to be bound up with the socio-aesthetic strategies underpinning changes to the sensory urban environment of the future. Fourth, we have to question what in situ experience is all about. Three major research pointers enable to address this issue: the embodiment of situated experiences, the porous nature of sensory spaces, and the sensory efficiency of the build environment. Ambiances sensitize urban design as well as social lifeforms.

description: While waiting for new gamma-ray burst detections, the Burst Alert Telescope (BAT) on board Swift covers each day ~50% of the sky in the hard X-ray band (``Survey data''). The large field of view (FOV), high sensitivity and good angular resolution make BAT a potentially powerful all-sky hard X-ray monitor, provided that mask--related systematics can be properly accounted for. We have developed and tested a complete procedure entirely based on public Swift/BAT software tools to analyse BAT Survey data, aimed at assessing the flux and spectral variability of bright sources in the 15-150 keV energy range. Detailed tests of the capabilities of our procedure were performed focusing, in particular, on the reliability of spectral measurements over the entire BAT FOV. First, we analyzed a large set of Crab observations, spread over ~7 months. Next, we studied the case of GRO J1655-40, a strongly variable source, which experienced a 9-month long outburst, beginning on February 2005. Such an outburst was systematically monitored with the well-calibrated PCA and HEXTE instruments on board the RXTE mission. Thanks to the good BAT temporal coverage of the source, we have been able to cross-check BAT light-curves with simultaneous HEXTE ones. The Crab tests have shown that our procedure recovers both the flux and the source spectral shape over the whole FOV of the BAT instrument. Moreover, by cross-checking GRO J1655-40 light-curves obtained by BAT and HEXTE, we found the spectral and flux evolution of the outburst to be in very good agreement. Using our procedure, BAT reproduces HEXTE fluxes within a 10-15% uncertainty with a 3sigma sensitivity of ~20 mCrab for an on-axis source, thus establishing its capability to monitor the evolution of relatively bright hard X-rays sources.

description: In the recent years, the domain of fast flow field prediction has been vastly dominated by pixel-based convolutional neural networks. Yet, the recent advent of graph convolutional neural networks (GCNNs) have attracted a considerable attention in the computational fluid dynamics (CFD) community. In this contribution, we proposed a GCNN structure as a surrogate model for laminar flow prediction around 2D obstacles. Unlike traditional convolution on image pixels, the graph convolution can be directly applied on body-fitted triangular meshes, hence yielding an easy coupling with CFD solvers. The proposed GCNN model is trained over a data set composed of CFD-computed laminar flows around 2,000 random 2D shapes. Accuracy levels are assessed on reconstructed velocity and pressure fields around out-of-training obstacles, and are compared with that of standard U-net architectures, especially in the boundary layer area.

description: The effect of the magnetic field on a capacitor with a superconducting electrode is studied within the Ginzburg-Landau approach. It is shown that the capacitance has a discontinuity at the onset of the surface superconductivity $B_{\rm c3}$ which is expressed as a discontinuity in the penetration depth of the electric field into metals. Estimates show that this discontinuity is observable with recent bridges for both conventional and high-$T_{\rm c}$ superconductors of the type-II.

description: All robots create consequential sound -- sound produced as a result of the robot's mechanisms -- yet little work has explored how sound impacts human-robot interaction. Recent work shows that the sound of different robot mechanisms affects perceived competence, trust, human-likeness, and discomfort. However, the physical sound characteristics responsible for these perceptions have not been clearly identified. In this paper, we aim to explore key characteristics of robot sound that might influence perceptions. A pilot study from our past work showed that quieter and higher-pitched robots may be perceived as more competent and less discomforting. To better understand how variance in these attributes affects perception, we performed audio manipulations on two sets of industrial robot arm videos within a series of four new studies presented in this paper. Results confirmed that quieter robots were perceived as less discomforting. In addition, higher-pitched robots were perceived as more energetic, happy, warm, and competent. Despite the robot's industrial purpose and appearance, participants seemed to prefer more "cute" (or "kawaii") sound profiles, which could have implications for the design of more acceptable and fulfilling sound profiles for human-robot interactions with practical collaborative robots.

description: From the simplest models to complex deep neural networks, modeling turbulence with machine learning techniques still offers multiple challenges. In this context, the present contribution proposes a robust strategy using patch-based training to learn turbulent viscosity from flow velocities, and demonstrates its efficient use on the Spallart-Allmaras turbulence model. Training datasets are generated for flow past two-dimensional (2D) obstacles at high Reynolds numbers and used to train an auto-encoder type convolutional neural network with local patch inputs. Compared to a standard training technique, patch-based learning not only yields increased accuracy but also reduces the computational cost required for training.

description: Context. Infrared spectroscopy of star and planet forming regions is at the dawn of a new age with the upcoming James Webb Space Telescope. In support of these observations, laboratory spectra are required to identify complex organic molecules in the ices that cover the dust grains in these regions. Aims. This study aims to provide reference spectra to firmly detect icy methyl formate in the different stages of star and planet forming regions. Methyl formate is mixed in astronomically relevant matrices, and the peak positions, FWHMs, and relative band intensities are characterized for different temperatures to provide an analytical tool for astronomers. Methods. Methyl formate is deposited at 15 K under high-vacuum conditions. Specifically, methyl formate is deposited pure and mixed with CO, H$_2$CO, CH$_3$OH, H$_2$O, and CO:H$_2$CO:CH$_3$OH combined. Throughout the experiment infrared spectra are acquired with a FTIR spectrometer in the range from 4000-500 cm$^{-1}$ (2.5-20 $μ$m) at a spectral resolution of 0.5 cm$^{-1}$. Results. We present the characterization of five solid-state methyl formate vibrational modes in pure and astronomically relevant ice matrices. The five selected vibrational modes, namely the C=O stretch, C$-$O stretch, CH$_3$ rocking, O$-$CH$_3$ stretching, and OCO deformation, are best suited for a JWST identification of methyl formate. For each of these vibrational modes, and each of the mixtures the TvS heatmaps, peak position versus FWHM, and relative band intensities are given. Additionally, the acquired reference spectra of methyl formate are compared with Spitzer observations of HH 46. A tentative detection of methyl formate provides an upper limit to the column density of $1.7\times10^{17}$ cm$^{-2}$, corresponding to an upper limit relative to water of $\leq 2.2\%$ and $\leq 40\%$ with respect to methanol.

Query Embedding Pruning for Dense Retrieval

subject: FOS: Computer and information sciences

description: Recent advances in dense retrieval techniques have offered the promise of being able not just to re-rank documents using contextualised language models such as BERT, but also to use such models to identify documents from the collection in the first place. However, when using dense retrieval approaches that use multiple embedded representations for each query, a large number of documents can be retrieved for each query, hindering the efficiency of the method. Hence, this work is the first to consider efficiency improvements in the context of a dense retrieval approach (namely ColBERT), by pruning query term embeddings that are estimated not to be useful for retrieving relevant documents. Our proposed query embeddings pruning reduces the cost of the dense retrieval operation, as well as reducing the number of documents that are retrieved and hence require to be fully scored. Experiments conducted on the MSMARCO passage ranking corpus demonstrate that, when reducing the number of query embeddings used from 32 to 3 based on the collection frequency of the corresponding tokens, query embedding pruning results in no statistically significant differences in effectiveness, while reducing the number of documents retrieved by 70%. In terms of mean response time for the end-to-end to end system, this results in a 2.65x speedup.
Fully anisotropic finite strain viscoelasticity based on a reverse multiplicative decomposition and logarithmic strains

description: In this paper we present a novel formulation for phenomenological anisotropic finite visco-hyperelasticity. The formulation is based on a multiplicative decomposition of the equilibrated deformation gradient into nonequilibrated elastic and viscous contributions. The proposal in this paper is a decomposition reversed respect to that from Sidoroff allowing for anisotropic viscous contributions. Independent anisotropic stored energies are employed for equilibrated and non-equilibrated parts. The formulation uses logarithmic strain measures in order to be teamed with spline-based hyperelasticity. Some examples compare the results with formulations that use the Sidoroff decomposition and also show the enhanced capabilities of the present model.

Subsequently, the existence and stability of the skyrmion solutions existing on the lattice are investigated. One consequence of the proposed models is that the corresponding discrete skyrmions have a high degree of stability, similar to their continuum counterparts.

description: We use the induced geometry on the two dimensional transverse cross section of a photon beam propagating on a perturbed Friedmann-Robertson-Walker (FRW) spacetime to find the Cosmic Microwave Background (CMB) photon distribution over a telescope's collecting area today. It turns out that at each line of sight the photons are diluted along a transverse direction due to gravitational shearing. The effect can be characterized by two spin-weight-two variables, which are reminiscent of the Stokes polarization parameters. Similar to that case, one can construct a scalar and a pseudo-scalar function where the latter only gets contributions from the tensor modes. We analytically determine the power spectrum of the pseudo-scalar at superhorizon scales in a simple inflationary model and briefly discuss possible observational consequences.

Material.—Early Pliocene: one right dentary (NMNHU-P 53/4245, Obukhovka 1); one left and two right dentaries (NMNHU-P 42/513, 532, 1252, Kamenskoe). Late Pliocene: two palatines (NMNHU-P 53/4246, 4247, Obukhovka 2); one left dentary (NMNHU-P 53/4248, Kryzhanovka); one left and one right dentary (NMNHU-P 45/6017, 6018, Cherevichne 2). Early Pleistocene: one left dentary and one palatine (NMNHU-P 41/2452, 2453, Kotlovina 2); two left dentaries and two palatines (NMNHU-P 41/2454–2457, Kotlovina 3).
Emended diagnosis.— Esox moldavicus differs from other esocids by (i) the predominance of one-row dentition on dentary; (ii) moderately developed dental shelf; (iii) high articular wall (articular angle more than 60°); (iv) caudally narrowed anterior medial crest on parasphenoid; (v) weakly visible grooves of carotid arteries on parasphenoid; (vi) presence of groove on anterior part of palatine.
Description.—The dentary has a moderately developed shelf, without symphysial notch (Fig. 3A, C–F, H; Table 3). There is one complete tooth row at the symphysis, and a few small teeth in a second row. The profile of the dentary is low, and the ventral bulge near the symphysis is almost not expressed. The ventral keel is narrow, as is especially clearly visible in the symphysial area.
The toothed surface on the palatine is short and not concave, extending under the maxillary process. The dorsal surface of the bone is curved. There are four or five rows of small tooth bases on the ventral side of the palatine (Fig. 3B, G). Widths of bones from the Obukhovka 2 are 3.1 and 4.2 mm, and from Kotlovina 2 4.7 mm.
Remarks.—Described bones are comparable in morphology to those of Esox moldavicus. This species resembles Esox sibiricus in the structure of the dentigerous surface of the palatine, but differs in the predominance of the one-row dentition at the dentary symphysis. The orientation of the maxillary process on the palatine and the low dentary are similar to those in Esox lucius, but differ from features of E. reichertii (Sytchevskaya, 1976).

description: Recent neural rendering approaches for human activities achieve remarkable view synthesis results, but still rely on dense input views or dense training with all the capture frames, leading to deployment difficulty and inefficient training overload. However, existing advances will be ill-posed if the input is both spatially and temporally sparse. To fill this gap, in this paper we propose a few-shot neural human rendering approach (FNHR) from only sparse RGBD inputs, which exploits the temporal and spatial redundancy to generate photo-realistic free-view output of human activities. Our FNHR is trained only on the key-frames which expand the motion manifold in the input sequences. We introduce a two-branch neural blending to combine the neural point render and classical graphics texturing pipeline, which integrates reliable observations over sparse key-frames. Furthermore, we adopt a patch-based adversarial training process to make use of the local redundancy and avoids over-fitting to the key-frames, which generates fine-detailed rendering results. Extensive experiments demonstrate the effectiveness of our approach to generate high-quality free view-point results for challenging human performances under the sparse setting.

description: The widely existing shallow decay phase of the X-ray afterglows of gamma-ray bursts (GRBs) is generally accepted to be due to long-lasting energy injection. The outflows carrying the injecting energy, based on the component that is dominative in energy, fall into two possible types: baryon-dominated and lepton-dominated ones. The former type of outflow could be ejecta that is ejected during the prompt phase of a GRB and consists of a series of baryonic shells with a distribution of Lorentz factors, and the latter type could be an electron-positron-pair wind that is driven by the post-burst central engine. We here provide a unified description for the dynamics of fireballs based on these two types of energy injection, and calculate the corresponding high-energy photon emission by considering synchrotron radiation and inverse Compton scattering (including synchrotron self-Compton and combined inverse-Compton) of electrons. We find that, in the two energy-injection models, there is a plateau (even a hump) in high-energy light curves during the X-ray shallow decay phase. In particular, a considerable fraction of the injecting energy in the lepton-dominated model can be shared by the long-lasting reverse shock since it is relativistic. Furthermore, almost all of the energy of the reverse shock is carried by leptons, and thus the inverse-Compton emission is enhanced dramatically. Therefore, this model predicts more significant high-energy afterglow emission than the baryon-dominated model. We argue that these observational signatures would be used to discriminate between different energy-injection models in the upcoming {\em Gamma-ray Large Area Space Telescope} (GLAST) era.

description: Отдел рукописей РНБ располагает богатым собранием архивов XVIII–XXI вв. Это личные архивные фонды, документы учреждений, разнообразные коллекции и отдельные поступления. Как правило, состав документов архивов весьма неоднородный: это письма и дневники, официальные бумаги и альбомы, рисунки и фотографии. Повреждения могут быть обусловлены не только характером бытования, последующего хранения и использования, но и спецификой самих документов (видом материала носителя и записи информации, наличием вложений, в том числе растительных). В ходе экспертной оценки составляются паспорта состояния документов, разработанные для каждой конкретной коллекции с учетом ее специфики. На основе паспортов формируется электронная база. Для характеристики состояния документа используются методы, основанные на исследовании микропроб, и неразрушающие методы (химические, оптические, анализ цифровых изображений).

Disclosure, risk sharing, and valuation under asymmetric information
Creators: name: Hughes, Patricia J.
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation analyzes risk sharing between an entrepreneur of a firm and its investors, and valuation of the firm when there is an informational asymmetry between the entrepreneur and investors. Two types of informational asymmetries are examined: the adverse selection problem and the moral hazard problem. In the adverse selection problem, the entrepreneur knows an exogenous parameter of value which is unobservable by investors. While maximizing his own welfare, he selects a level of direct disclosure in order to communicate his information to investors. A verification role for a third party is developed such that the verified disclosure is credible due to a costly penalty which is imposed if the disclosure is false. An equilibrium is derived in which investors correctly value the firm after observing the disclosure. In the moral hazard problem, firm value is dependent upon the behavior of the entrepreneur where that behavior is unobservable. The entrepreneur selects costly ownership in his own firm to credibly communicate his behavior to investors. An equilibrium is derived in which investors correctly value the firm after observing the entrepreneur's investment portfolio. In the conclusion, the two informational problems are integrated in order to indicate the similar nature of the problems.

description: Using one-dimensional hydrodynamic simulations including interstellar heating, cooling, and thermal conduction, we investigate nonlinear evolution of gas flow across galactic spiral arms. We model the gas as a non-self-gravitating, unmagnetized fluid, and follow its interaction with a stellar spiral potential in a local frame comoving with the stellar pattern. Initially uniform gas rapidly separates into warm and cold phases as a result of thermal instability (TI), and also forms a quasi-steady shock that prompts phase transitions. After saturation, the flow follows a recurring cycle: warm and cold phases in the interarm region are shocked and immediately cool to become a denser cold medium in the arm; post-shock expansion reduces the mean density to the unstable regime in the transition zone and TI subsequently mediates evolution back into warm and cold interarm phases. For our standard model with n_0 = 2 cm^-3, the gas resides in the dense arm, thermally-unstable transition zone, and interarm region for 14%, 22%, 64% of the arm-to-arm crossing time. These regions occupy 1%, 16%, and 83% of the arm-to-arm distance, respectively. Gas at intermediate temperatures represents ~25-30% of the total mass, similar to the fractions estimated from HI observations. Despite transient features and multiphase structure, the time-averaged shock profiles can be matched to that of a diffusive isothermal medium with temperature 1,000 K and "particle" mean free path of l_0 = 100 pc. Finally, we quantify numerical conductivity associated with translational motion of phase-separated gas on the grid, and show that convergence of numerical results requires the numerical conductivity to be comparable to or smaller than the physical conductivity.

description: In the era of precision cosmology and ever-improving cosmological simulations, a better understanding of different galaxy components such as bulges and discs will give us new insight into galactic formation and evolution. Based on the fact that the stellar populations of the constituent components of galaxies differ by their dynamical properties, we develop two simple models for galaxy decomposition using the IllustrisTNG cosmological hydrodynamical simulation. The first model uses a single dynamical parameter and can distinguish 4 components: thin disc, thick disc, counter-rotating disc and bulge. The second model uses one more dynamical parameter, was defined in a probabilistic manner, and distinguishes two components: bulge and disc. The number fraction of disc-dominated galaxies at a given stellar mass obtained by our models agrees well with observations for masses exceeding $ \log_{10}(M_*/M_\odot)=10$. Sérsic indices and half-mass radii for the bulge components agree well with those for real galaxies. The mode of the distribution of Sérsic indices for the disc components is at the expected value of $n=1$. However, disc half-mass radii are smaller than those for real galaxies, in accordance with previous findings that the IllustrisTNG simulation produces undersized discs.

description: We present the results of population syntheses for binary stars carried out using the ``Scenario Machine'' code with the aim of analyzing events that may result in long gamma-ray bursts. We show that the observed distribution of morphological types of the host galaxies of long gamma-ray bursts can be explained in a model in which long gamma-ray bursts result from the core collapse of massive Wolf-Rayet stars in close binaries. The dependence of the burst rate on galaxy type is associated with an increase in the rate of stellar-wind mass-loss with increasing stellar metallicity. The separation of binary components at the end of their evolution increases with the stellar-wind rate, resulting in a reduction of the number of binaries that produce gamma-bursts.

Supersolid-like states in a two-dimensional trapped spin-orbit-coupled spin-1 condensate

description: We study supersolid-like states in a quasi-two-dimensional trapped Rashba and Dresselhaus spin-orbit (SO) coupled spin-1 condensate. For small strengths of SO coupling $γ$ ($γ\lessapprox 0.75$), in the ferromagnetic phase, circularly-symmetric $(0,\pm 1, \pm 2)$- and $(\mp 1, 0,\pm 1)$-type states are formed where the numbers in the parentheses denote the angular momentum of the vortex at the center of the components and where the upper (lower) sign correspond to Rashba (Dresselhaus) coupling; in the antiferromagnetic phase, only $(\mp 1, 0,\pm 1)$-type states are formed. For large strengths of SO coupling, supersolid-like superlattice and superstripe states are formed in the ferromagnetic phase. In the antiferromagnetic phase, for large strengths of SO coupling, supersolid-like superstripe and multi-ring states are formed. For an equal mixture of Rashba and Dresselhaus SO couplings, only a superstripe state is found. All these states are found to be dynamically stable and hence accessible in an experiment and will enhance the fundamental understanding of crystallization onto spatially periodic states in solids.

description: We explore variations of the dust extinction law of the Milky Way by selecting stars from the Swift/UVOT Serendipitous Source Catalogue, cross-matched with Gaia DR2 and 2MASS to produce a sample of 10,452 stars out to ~4kpc with photometry covering a wide spectral window. The near ultraviolet passbands optimally encompass the 2175A bump, so that we can simultaneously fit the net extinction, quoted in the V band (A$_V$), the steepness of the wavelength dependence ($δ$) and the bump strength (E$_b$). The methodology compares the observed magnitudes with theoretical stellar atmospheres from the models of Coelho. Significant correlations are found between these parameters, related to variations in dust composition, that are complementary to similar scaling relations found in the more complex dust attenuation law of galaxies - that also depend on the distribution of dust among the stellar populations within the galaxy. We recover the strong anticorrelation between A$_V$ and Galactic latitude, as well as a weaker bump strength at higher extinction. $δ$ is also found to correlate with latitude, with steeper laws towards the Galactic plane. Our results suggest that variations in the attenuation law of galaxies cannot be fully explained by dust geometry.
