description: The dynamics of a neutron star after a glitch involve the transfer of angular momentum from the crust (where the glitch is presumed to originate) to the liquid core, causing the core to spin up. The crust-core coupling, which determines how quickly this spin-up proceeds, can be achieved through various physical processes, including Ekman pumping, superfluid vortex-mediated mutual friction, and magnetic fields. Although the complex nature of these mechanisms has made it difficult to study their combined effects, analytical estimations for individual processes reveal that spin-up timescales vary according to the relative strength of Coriolis, viscous, and mutual friction forces, as well as the magnetic field. However, experimental and numerical validations of those analytical predictions are limited. In this paper, we focus on viscous effects and mutual friction. We conduct non-linear hydrodynamical simulations of the spin-up problem in a two-component fluid by solving the incompressible Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations in the full sphere (i.e., including $r=0$) for the first time. We find that the viscous (normal) component accelerates due to Ekman pumping, although the mutual friction coupling to the superfluid component alters the spin-up dynamics compared to the single-fluid scenario. Close to the sphere's surface, the response of the superfluid is accurately described by the mutual friction timescale irrespective of its coupling strength with the normal component. However, as we move deeper into the sphere, the superfluid accelerates on different timescales due to the slow viscous spin-up of the internal normal fluid layers. We discuss potential implications for neutron stars and requirements for future work to build more realistic models.

description: WASP-12b is one of the most well-studied transiting exoplanets, as its highly-inflated radius and its 1.1 day orbit around a G0-type star make it an excellent target for atmospheric categorisation through observation during its secondary eclipse. We present two new secondary eclipse observations of WASP-12b, acquired a year apart with the Wide Field Camera on the Isaac Newton Telescope (INT) and the IO:O instrument on the Liverpool Telescope (LT). These observations were conducted in the $i^\prime$-band, a window expected to be dominated by TiO features if present in appreciable quantities in the upper atmosphere. We measured eclipse depths that disagree with each other by $\sim$3$σ$ (0.97 $\pm$ 0.14 mmag on the INT and 0.44 $\pm$ 0.21 mmag on the LT), a result that is mirrored in previous $z^\prime$-band secondary eclipse measurements for WASP-12b. We explore explanations for these disagreements, including systematic errors and variable thermal emission in the dayside atmosphere of WASP-12b caused by temperature changes of a few hundred Kelvin: a possibility we cannot rule out from our analysis. Full-phase curves observed with TESS and CHEOPS have the potential to detect similar atmospheric variability for WASP-12b and other optimal targets, and a strategic, multi-telescope approach to future ground-based secondary eclipse observations is required to discriminate between explanations involving storms and systematics.

description: Some comments in honour of K. Alex Müeller are presented, reflecting the ground-shift in superconductivity and solid-state physics that followed his discovery, along with Bednorz, of cuprate superconductors. This has led to a broad and growing suite of applications encompassing all sectors of society – energy, transport, health, space, communications, defence and research. It established a net of friendships and collaborations around the globe. It also created a long-standing puzzle as to the microscopic origins of high-temperature superconductivity that has challenged some of the greatest minds in solid-state physics, and still continues to do so.

 Remarks. Colonies examined here were quite small and lacked gonophores, but they corresponded with Eudendrium arbuscula Wright, 1859 as described by Schuchert (2008b). The largest colony had a polysiphonic stem basally that lacked a bark-like covering as in the similar E. annulatum Norman, 1864; hydranths were small and bore a basal band of large microbasic euryteles having a straight shaft.
 The specific name arbuscula Wright, 1859, as published in the binomen Eudendrium arbuscula, was conserved and placed on the Official List of Specific Names in Zoology (ICZN Opinion 1956). It had been threatened by a senior secondary homonym, arbuscula (d’Orbigny, 1846), as published in the binomen Tubularia arbuscula, a name placed in the same Opinion on the Official Index of Rejected and Invalid Specific Names in Zoology. Also placed on the Official Index in that Opinion was the name E. wrightii Hartlaub, 1905, a replacement name for E. arbuscula Wright. As noted by a number of authors (e.g., Marques & Vervoort 1999; Schuchert 2008b), the specific name is a noun in apposition and correctly spelled as “ arbuscula,” not “ arbusculum.”
 Eudendrium arbuscula, a relatively shallow water species, has been reported several times from the west coast of Sweden (see Checklist), from Denmark (Kramp 1935b; Schuchert 2008b), and from the Oslofjord, Norway (Christiansen 1972).
 Reported distribution. West coast of Sweden.—Bohuslän (Marques et al. 2000) to Malösund (Jäderholm 1909, as E. wrighti).
Elsewhere.—North Atlantic: Norway to Brittany (Schuchert 2008b); northern Canada (Calder 1972).

Structure and Parametrization of Generic Stochastic Maps of Density Matrices

Year: 2002
Subjects: subject: Quantum Physics (quant-ph)

description: The most general evolution of the density matrix of a quantum system with a finite-dimensional state space is by stochastic maps which take a density matrix linearly into the set of density matrices. These dynamical stochastic maps form a linear convex set that may be viewed as supermatrices. The property of hermiticity of density matrices renders an associated supermatrix hermitian and hence diagonalizable. The positivity of the density matrix does not make the associated supermatrix positive though. If the map itself is positive, it is called completely positive and they have a simple parameterization. This is extended to all positive (not completely positive) maps. A general dynamical map that does not preserve the norm of the density matrices it acts on can be thought of as the contraction of a norm-preserving map of an extended system. The reconstruction of such extended dynamics is also given.

description: In this paper, we suggest an open eco system model “Community- based living lab” to support people with dementia for safe and happy living. In this model, instead of establishing a closed and secure area for people with dementia, open and reciprocal communities are proposed as one of the optimal strategies for future aging society. The suggested open community is characterized with co-creation among people with dementia, industrial partners, municipalities, local care institutions, and citizens, and living lab where stakeholders conduct diverse experimental and spontaneous initiatives. We first introduce and analyze a case in Omuta city, Japan, and then extract success factors of the Omuta’s dementia care programs. The community-based living lab in Omuta’s contributes to enhancing Omuta’s success and provides sustainable improvements to the fast-chaining social infrastructure for wider aging communities. Finally, we discuss the critical aspects of the model.

description: We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V = $-$19.95 $\pm$ 0.08, this object is one of the brightest Type II SNe, and lies in the gap of magnitudes between the majority of Type II SNe and the superluminous SNe. Its light curve shows little evidence of the expected drop from the optically thick phase to the radioactively powered tail. The velocities derived from the absorption in H$α$ are also unusually high with the blue edge tracing the fastest moving gas initially at 20000 km s$^{-1}$, and then declining approximately linearly to 15000 km s$^{-1}$ over $\sim$100 d. The dwarf host galaxy of the SN indicates a low-metallicity progenitor which may also contribute to the weakness of the metal lines in its spectra. We examine SN 2016gsd with reference to similarly luminous, linear Type II SNe such as SNe 1979C and 1998S, and discuss the interpretation of its observational characteristics. We compare the observations with a model produced by the JEKYLL code and find that a massive star with a depleted and inflated hydrogen envelope struggles to reproduce the high luminosity and extreme linearity of SN 2016gsd. Instead, we suggest that the influence of interaction between the SN ejecta and circumstellar material can explain the majority of the observed properties of the SN. The high velocities and strong H$α$ absorption present throughout the evolution of the SN may imply a circumstellar medium configured in an asymmetric geometry.

description: Links is a web programming language under development in Edinburgh aimed at simplifying web development. Conventional multi-tier applications involve programming in several languages for different layers, and the mismatches between these layers and abstractions need to be handled by the programmer, which can lead to costly errors or security vulnerabilities. In Links, programs combine all of the code of a web application in a single program, and the implementation generates appropriate JavaScript and HTML for the client, and SQL queries for the database. However, installing and using Links is non-trivial, making it difficult for new programmers to get started and learn about Links. This paper reports on a Web-based "TryLinks" system, allowing anyone to experiment with Links without going through the installation process. TryLinks was designed with two major functionalities: an interactive Links shell that teaches the basic syntax of Links and acts as a playground, as well as a short tutorial series on how Links is used in practical web development. Tutorials can also be created or modified by administrators. We present the design and implementation of TryLinks, and conclude with discussion of lessons learned from this project and remaining challenges for Web-based tutorials for Web programming languages.

description: The accurate description of the interaction of a quantum system with a its environment is a challenging problem ubiquitous across all areas of physics, and lies at the foundation of quantum mechanics theory. Here we pioneer a new strategy to create discrete low-rank models of the system-environment interaction, by exploiting the frequency and time domain information encoded in the fluctuation-dissipation relation connecting the system-bath correlation function and the spectral density. We demonstrate the effectiveness of our methodology by combining it with tensor-network methodologies and simulating the quantum dynamics of a complex excitonic systems in a highly structured bosonic environment. The new modeling framework sets the basis for a leap in the analysis of open quantum systems providing controlled accuracy at significantly reduced computational costs, with benefits in all connected research areas.

description: We study different estimators of the radius of convergence of the Taylor series of the pressure in finite density QCD. We adopt the approach in which the radius of convergence is estimated first in a finite volume, and the infinite-volume limit is taken later. This requires an estimator for the radius of convergence that is reliable in a finite volume. Based on general arguments about the analytic structure of the partition function in a finite volume, we demonstrate that the ratio estimator cannot work in this approach, and propose three new estimators, capable of extracting reliably the radius of convergence, which coincides with the distance from the origin of the closest Lee-Yang zero. We also provide an estimator for the phase of the closest Lee-Yang zero, necessary to assess whether the leading singularity is a true critical point. We demonstrate the usage of these estimators on a toy model, namely 4 flavors of unimproved staggered fermions on a small $6^3 \times 4$ lattice, where both the radius of convergence and the Taylor coefficients to any order can be obtained by a direct determination of the Lee-Yang zeros. Interestingly, while the relative statistical error of the Taylor expansion coefficients steadily grows with order, that of our estimators stabilizes, allowing for an accurate estimate of the radius of convergence. In particular, we show that despite the more than 100\% error bars on high-order Taylor coefficients, the given ensemble contains enough information about the radius of convergence.

description: In early 2018, design students came together with long-term care facility residents to co-write and also co-design a series of small publications that would focus on the life and experiences of the residents. Small groups of 2-3 students were paired with 1-3 residents and asked to produce a mini- publication over a series of 6 meetings. Entitled Zeitgeist, this project brings together students, residents, their families and care facility staff, creating the opportunity for meaning exchange and interaction between all parties. It can offer residents a voice and opportunity for true creative expression and stimulation through meaningful activities, while simultaneously providing a rich community-based learning experience for design students. Zeitgeist Vancouver was inspired by the Zeitgeist Kollektiv, a public editorial design and storytelling project within a care facility in Zurich, led by Carolyn Kerchof and Martina Regli.

description: Domestic income multipliers associated with U.S. exports of processed and other high-value agricultural products such as meats and manufactured foods are shown to be about 55 percent greater than those for exports of primary agricultural commodities such as grains and oilseeds. About 90 percent of the high-value product exports originate in the food manufacturing industries. Yet, when expressed in terms of export propensity, the external market performance of U.S. food manufacturers trails substantially behind that of similar industries in other countries. The U.S. food manufacturing industries are characterized by competitive imperfections such as product differentiation, scale economies, and seller concentration. Traditional international trade theories based on factor endowment constructs have not proved robust in explaining trade flows under such imperfectly competitive conditions. Recently some economists have applied industrial organization concepts to international markets that are imperfectly competitive. Linkages have been established both between elements of imperfect competition and external market performance, and between international trade and economic welfare in imperfectly competitive markets. This paper reports on an industrial organization-based analysis of the export market performance of U.S. food manufacturers. The analysis utilizes panel data from 78 leading food processing firms and cross-sectional Census data from 42 4-digit SIC food manufacturing industries. Export market performance varies widely among these firms and industries. About 84 percent of the variation was explained through the use of industrial organization characteristics as explanatory variables in regression analysis. Food manufacturer export propensity was found to be significantly and positively related to firm size, research and development, and product transportability, and significantly and negatively related to advertising, vertical coordination in sourcing of raw agricultural commodities, wage rates, and height of foreign import barriers. Other explanatory variables that show promise, pending adequate data, include the extent to which firms operate foreign plants, seller concentration, and investor vs. cooperative firm ownership. Alternative measures of international market performance, including export market share, relative export advantage, and revealed competitiveness, are also examined.

Previous studies have shown that the KZ-like scaling behavior also lies in the topological transitions in the Qi-Wu-Zhang model (2D) and the Su-Schrieffer-Heeger model (1D), although symmetry breaking does not exist here. Both models with linear band crossings give that $ν=1$ and $z=1$. We wonder whether different critical exponents can be acquired in topological transitions beyond linear band crossing. In this work, we look into the KZ behavior in a topological 2D checkerboard lattice with a quadratic band crossing. We investigate from dual perspectives: momentum distribution of the Berry curvature in clean systems for simplicity, and real-space analysis of domain-like local Chern marker configurations in disordered systems, which is a more intuitive analog to conventional KZ description. In equilibrium, we find the correlation length diverges with a power $ν\simeq 1/2$. Then, by slowly quenching the system across the topological phase transition, we find that the freeze-out time $t_\mathrm{f}$ and the unfrozen length scale $ξ(t_\mathrm{f})$ both satisfy the KZ scaling, verifying $z\simeq 2$. We subsequently explore KZ behavior in topological phase transitions with other higher-order band crossing and find the relationship between the critical exponents and the order. Our results extend the understanding of the KZ mechanism and non-equilibrium topological phase transitions.

 Remarks. The biology and distribution of Podocoryna carnea M. Sars, 1846 have been reviewed by Edwards (1972) and Schuchert (2008a). Reports of this species outside northwestern Europe are now considered erroneous.
 Classification of Hydractiniidae at the generic level remains unsettled. For reasons given elsewhere (Calder 2010), Podocoryna M. Sars, 1846, sometimes included in the synonymy of Hydractinia Van Beneden, 1844a, is recognized here as a distinct genus pending further study.
 The hydroid Podocoryna carnea is common in waters of Denmark (Kramp 1935b, as Hydractinia carnea), the west coast of Sweden (Jägerskiöld 1971: 62, as H. carnea), and the Oslofjord, Norway (Christiansen 1972). Colonies become dormant or largely dormant in the region during winter (Kramp 1935b; Christiansen 1972).
 Reported distribution. West coast of Sweden.—From Koster area (Jägerskiöld 1971) to the Öresund (Lönnberg 1898).
Elsewhere.—Northern Europe, from Norway to the British Isles (Schuchert 2008a).

description: The current GATT negotiations on farm policy are aimed at removing distortions in the international trade of agricultural products. However, a large proportion of the world's trade in food and agricultural products occurs in high-value processed food products where markets can often be described as having imperfectly competitive market structures, characterised by high seller concentration, economies of scale and product differentiation. In this context, recent developments in the international economics literature have focussed on the impact of imperfect competition in international markets. In particular, a theoretical rationale has been given for the use of protectionist trade policies. Therefore, the overall aim of this paper is to explore the relevance of these theoretical developments to trade in highly processed food and related products. The paper is outlined as follows: Section 1 presents an outline of the arguments for active trade policy where markets are imperfectly competitive. Section 2 considers the optimal policies for an exporting and importing country respectively. The results indicate that even though export subsidies and import tariffs may be justified, such policies may be inferior to alternative forms of trade intervention such as maximum export and import prices. The application of the theoretical results to the US brewing and processed cheese sectors is presented in Section 3, whilst Section 4 provides a summary and conclusion.

description: Determining the strength of non-linear statistical dependencies between two variables is a crucial matter in many research fields. The established measure for quantifying such relations is the mutual information. However, estimating mutual information from limited samples is a challenging task. Since the mutual information is the difference of two entropies, the existing Bayesian estimators of entropy may be used to estimate information. This procedure, however, is still biased in the severely under-sampled regime. Here we propose an alternative estimator that is applicable to those cases in which the marginal distribution of one of the two variables---the one with minimal entropy---is well sampled. The other variable, as well as the joint and conditional distributions, can be severely undersampled. We obtain an estimator that presents very low bias, outperforming previous methods even when the sampled data contain few coincidences. As with other Bayesian estimators, our proposal focuses on the strength of the interaction between two discrete variables, without seeking to model the specific way in which the variables are related. A distinctive property of our method is that the main data statistics determining the amount of mutual information is the inhomogeneity of the conditional distribution of the low-entropy variable in those states (typically few) in which the large-entropy variable registers coincidences.

description: We investigate the robustness of the many-body localized (MBL) phase to the quantum-avalanche instability by studying the dynamics of a localized spin chain coupled to a $T=\infty$ thermal bath through its leftmost site. By analyzing local magnetizations, we estimate the size of the thermalized sector of the chain and find that it increases logarithmically slowly in time. This logarithmically slow propagation of the thermalization front allows us to lower bound the slowest thermalization time, and find a broad parameter range where it scales fast enough with the system size that MBL is robust against thermalization induced by avalanches. The further finding that the imbalance -- a global quantity measuring localization -- thermalizes over a time scale exponential both in disorder strength and system size is in agreement with these results.

A torsion-free background solution of the string theory

Year: 2019
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We find a background solution of the string theory which has a special property distinguished from the usual background solutions. This background solution does not produce the NS-NS two-form fields under T-duality and therefore the background vacua described by this solution essentially do not involve NS-NS type branes in their configurations, unlikely to the case of the ordinary Calabi-Yau ansatz. As a result the non-linear $σ$-models, whose target space metrics are given by these T-dual partners, can both be torsion-free.

description: Ellerman bombs and UV bursts are transient brightenings that are ubiquitously observed in the lower atmospheres of active and emerging flux regions. Here we present inversion results of SST/CRISP and CHROMIS, as well as IRIS data of such transient events. Combining information from the Mg II h & k, Si IV and Ca II 8542A and Ca II H & K lines, we aim to characterise their temperature and velocity stratification, as well as their magnetic field configuration. We find average temperature enhancements of a few thousand kelvin close to the classical temperature minimum, but localised peak temperatures of up to 10,000-15,000 K from Ca II inversions. Including Mg II generally dampens these temperature enhancements to below 8000 K, while Si IV requires temperatures in excess of 10,000 K at low heights, but may also be reproduced with secondary temperature enhancements of 35,000-60,000 K higher up. However, reproducing Si IV comes at the expense of overestimating the Mg II emission. The line-of-sight velocity maps show clear bi-directional jet signatures and strong correlation with substructure in the intensity images, with slightly larger velocities towards the observer than away. The magnetic field parameters show an enhancement of the horizontal field co-located with the brightenings at similar heights as the temperature increase. We are thus able to largely reproduce the observational properties of Ellerman bombs with UV burst signature with temperature stratifications peaking close to the classical temperature minimum. Correctly modelling the Si IV emission in agreement with all other diagnostics is, however, an outstanding issue. Accounting for resolution differences, fitting localised temperature enhancements and/or performing spatially-coupled inversions is likely necessary to obtain better agreement between all considered diagnostics.

description: We describe the BOOMERanG experiment and its main result, i.e. the measurement of the large scale curvature of the Universe. BOOMERanG is a balloon-borne microwave telescope with sensitive cryogenic detectors. BOOMERanG has measured the angular distribution of the Cosmic Microwave Background on $\sim 3%$ of the sky, with a resolution of $\sim 10$ arcmin and a sensitivity of $\sim 20 μK$ per pixel. The resulting image is dominated by hot and cold spots with rms fluctuations $\sim 80 μK$ and typical size of $\sim 1^o$. The detailed angular power spectrum of the image features three peaks and two dips at $\ell = (213^{+10}_{-13}), (541^{+20}_{-32}), (845^{+12}_{-25})$ and $\ell = (416^{+22}_{-12}), (750^{+20}_{-750})$, respectively. Such very characteristic spectrum can be explained assuming that the detected structures are the result of acoustic oscillations in the primeval plasma. In this framework, the measured pattern constrains the density parameter $Ω$ to be $0.85 < Ω< 1.1$ (95% confidence interval). Other cosmological parameters, like the spectral index of initial density fluctuations, the density parameter for baryons, dark matter and dark energy, are detected or constrained by the BOOMERanG measurements and by other recent CMB anisotropy experiments. When combined with other cosmological observations, these results depict a new, consistent, cosmological scenario.

description: In this work, lateral displacements of transmitted and reflected spin waves at a 360 degree domain wall (360DW), which is referred to as the spin-wave Goos-Hänchen effect (SWGHE), are systematically investigated in magnetic heterostructures with perpendicular easy/hard axis and wall-extension direction. Similar to the counterpart at heterochiral interfaces, the interfacial Dzyaloshinskii-Moriya interactions (IDMI) originating from a heavy-metal substrate is important for the emergence of SWGHE. More interestingly, the SWGHE can even survive in ferromagnets with biaxial anisotropy (either intrinsic or caused by shape anisotropy) in the absence of IDMI due to the unique 360DW-induced potentials which are distinct to the well-known Pöschl-Teller ones. Numerics shows that these lateral displacements are generally fractions of the spin-wave wavelength. They can be further enhanced by an array of well-separated 360DWs thus provide a large variety for spin-wave manipulation.
