description: We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ($V=8.75$ mag, $K=7.15$ mag) solar twin HD 183579, delivered by the Transiting Exoplanet Survey Satellite (TESS). The host star is located $56.8\pm0.1$ pc away with a radius of $R_{\ast}=0.97\pm0.02\ R_{\odot}$ and a mass of $M_{\ast}=1.03\pm0.05\ M_{\odot}$. We confirm the planetary nature by combining space and ground-based photometry, spectroscopy, and imaging. We find that HD 183579b (TOI-1055b) has a radius of $R_{p}=3.53\pm0.13\ R_{\oplus}$ on a $17.47$ day orbit with a mass of $M_{p}=11.2\pm5.4\ M_{\oplus}$ ($3σ$ mass upper limit of $27.4\ M_{\oplus}$). HD 183579b is the fifth brightest known sub-Neptune planet system in the sky, making it an excellent target for future studies of the interior structure and atmospheric properties. By performing a line-by-line differential analysis using the high resolution and signal-to-noise ratio HARPS spectra, we find that HD 183579 joins the typical solar twin sample, without a statistically significant refractory element depletion.

description: We construct a minimal example of a supersymmetric grand unified model in a toroidal compactification of type I string theory with magnetized D9-branes. All geometric moduli are stabilized in terms of the background internal magnetic fluxes which are of "oblique" type (mutually non-commuting). The gauge symmetry is just SU(5) and the gauge non-singlet chiral spectrum contains only three families of quarks and leptons transforming in the $10+{\bar 5}$ representations.

arginal gains in accuracy of valuation from increasing the specificity of price indexes : empirical evidence for the Canadian economy
Creators: name: Jamal, Karim
Publisher: name: University of British Columbia
Year: 2010

description: In this paper we present empirical estimates of marginal gains in accuracy of asset valuation from increasing the specificity of price indexes used to adjust Historical Cost Financial Statements. The empirical evidence strongly suggests that the accuracy function for the Canadian economy is highly convex. This implies that the marginal gain in accuracy of valuation declines sharply as the number and specificity of price indexes used for valuation increases. These findings are potentially valuable for Auditors, Academics and Regulatory agencies who are involved in the debate on selection of asset valuation rules. The results are of particular relevance for selection of asset valuation rules when it is costly to use finer measurement methods. CICA handbook (Section 4510) presently allows companies to choose from several alternative methods for adjusting historical prices. In this paper we show the benefits obtained by using finer data, so that companies can made a decision as to the amount of resources they should invest to obtain finer data.

description: XTE J1701-407 is a new transient X-ray source discovered on June 8th, 2008. More than one month later it showed a rare type of thermonuclear explosion: a long type I X-ray burst. We report herein the results of our study of the spectral and flux evolution during this burst, as well as the analysis of the outburst in which it took place. We find an upper limit on the distance to the source of 6.1 kpc by considering the maximum luminosity reached by the burst. We measure a total fluence of 3.5*10^{-6} erg/cm^2 throughout the ~20 minutes burst duration and a fluence of 2.6*10^{-3} erg/cm^2 during the first two months of the outburst. We show that the flux decay is best fitted by a power law (index ~1.6) along the tail of the burst. Finally, we discuss the implications of the long burst properties, and the presence of a second and shorter burst detected by Swift ten days later, for the composition of the accreted material and the heating of the burning layer.

description: 1. Movement is the primary means by which animals obtain resources and avoid hazards. Most movement exhibits directional bias that is related to environmental features (taxis), such as the location of food patches, predators, ocean currents, or wind. Numerous behaviours with directional bias can be characterized by maintaining orientation at an angle relative to the environmental stimuli (menotaxis), including navigation relative to sunlight or magnetic fields and energy-conserving flight across wind. However, no statistical methods exist to flexibly classify and characterise such directional bias. 2. We propose a biased correlated random walk model that can identify menotactic behaviours by predicting turning angle as a trade-off between directional persistence and directional bias relative to environmental stimuli without making a priori assumptions about the angle of bias. We apply the model within the framework of a multi-state hidden Markov model (HMM) and describe methods to remedy information loss associated with coarse environmental data to improve the classification and parameterization of directional bias. 3. Using simulation studies, we illustrate how our method more accurately classifies behavioural states compared to conventional correlated random walk HMMs that do not incorporate directional bias. We illustrate the application of these methods by identifying cross wind olfactory foraging and drifting behaviour mediated by wind-driven sea ice drift in polar bears (Ursus maritimus) from movement data collected by satellite telemetry. 4. The extensions we propose can be readily applied to movement data to identify and characterize behaviours with directional bias toward any angle, and open up new avenues to investigate more mechanistic relationships between animal movement and the environment.

description: The purpose of the present experiment was to investigate whether the sensory weighting of a plantar pressure-based, tongue-placed tactile biofeedback for controlling posture could be subject to inter-individual variability. To achieve this goal, 60 young healthy adults were asked to stand as immobile as possible with their eyes closed in two conditions of No-biofeedback and Biofeedback. Centre of foot pressure (CoP) displacements were recorded using a force platform. Overall, results showed reduced CoP displacements in the Biofeedback relative to the No-biofeedback condition, evidencing the ability of the central nervous system to efficiently integrate an artificial plantar-based, tongue-placed tactile biofeedback for controlling posture during quiet standing. Results further showed a significant positive correlation between the CoP displacements measured in the No-biofeedback condition and the decrease in the CoP displacements induced by the use of the biofeedback. In other words, the degree of postural stabilization appeared to depend on each subject's balance control capabilities, the biofeedback yielding a greater stabilizing effect in subjects exhibiting the largest CoP displacements when standing in the No-biofeedback condition. On the whole, by evidencing a significant inter-individual variability in sensory weighting of an additional tactile information related to foot sole pressure distribution for controlling posture, the present findings underscore the need and the necessity to address the issue of inter-individual variability in the field of neuroscience.

description: Using four-dimensional unitarity and MHV-rules we calculate the one-loop MHV amplitudes with all external particles in the adjoint representation for N=2 supersymmetric QCD with N_f fundamental flavours. We start by considering such amplitudes in the superconformal N=4 gauge theory where the N=4 supersymmetric Ward identities (SWI) guarantee that all MHV amplitudes for all types of external particles are given by the corresponding tree-level result times a universal helicity- and particle-type-independent contribution. In N=2 SQCD the MHV amplitudes differ from those for N=4 for general values of N_f and N_c. However, for N_f=2N_c where the N=2 SQCD is conformal, the N=2 MHV amplitudes (with all external particles in the adjoint representation) are identical to the N=4results. This factorisation at one-loop motivates us to pose a question if there may be a BDS-like factorisation for these amplitudes which also holds at higher orders of perturbation theory in superconformal N=2 theory.

description: The (fractional) Brownian sheet is a simplest example of a Gaussian random field X whose covariance is the tensor product of a finite number (d) of nonnegative correlation functions of self-similar Gaussian processes. Let Y be the homogeneous Gaussian field obtained by applying to X the Lamperti transform, which involves the exponential change of time and the amplitude normalization to have unit variance. Under some assumptions, we prove the existence of the persistence exponents for both fields, X and Y, and find the relation between them. The exponent for X is the limit of ln1/P{X(t)<1, t in [0,T]^d}/(lnT)^d, T>>1. In terms of Y it has the form lim ln1/P{Y(t)<0,t in TG}/T^d:=Q, T>>1, where G is a suitable d-simplex and T is a similarity coefficient; G can be selected in form [0,c]^d if d=2 . The exponent Q exists for any continuous Gaussian homogeneous field Y with non-negative covariance when G is bounded region with a regular boundary. The problem of the existence and connection of exponents for X and Y was raised by Li and Shao [Ann. Probab. 32:1, 2004] and originally concerned the Brownian sheet.

description: A Pearson Effective Potential model for including quantization effects in the simulation of nanoscale nMOSFETs has been developed. This model, based on a realistic description of the function representing the non zero-size of the electron wave packet, has been used in a Monte-Carlo simulator for bulk, single gate SOI and double-gate SOI devices. In the case of SOI capacitors, the electron density has been computed for a large range of effective field (between 0.1 MV/cm and 1 MV/cm) and for various silicon film thicknesses (between 5 nm and 20 nm). A good agreement with the Schroedinger-Poisson results is obtained both on the total inversion charge and on the electron density profiles. The ability of an Effective Potential approach to accurately reproduce electrostatic quantum confinement effects is clearly demonstrated.

We will briefly illustrate here the constraints obtained by a collection of low energy observables including FCNC transitions, rare decays, leptonic and semileptonic decays of B mesons, as well as leptonic decays of K mesons. The theoretical predictions can be obtained using the computer program SuperIso.

description: There is a significant possibility that astrophysical black holes with nearly-extremal spins exist. Numerical simulations of such systems require suitable initial data. In this paper, we examine three methods of constructing binary-black-hole initial data, focusing on their ability to generate black holes with nearly-extremal spins: (i) Bowen-York initial data, including standard puncture data (based on conformal flatness and Bowen-York extrinsic curvature), (ii) standard quasi-equilibrium initial data (based on the extended-conformal-thin-sandwich equations, conformal flatness, and maximal slicing), and (iii) quasi-equilibrium data based on the superposition of Kerr-Schild metrics. We find that the two conformally-flat methods (i) and (ii) perform similarly, with spins up to about 0.99 obtainable at the initial time. However, in an evolution, we expect the spin to quickly relax to a significantly smaller value around 0.93 as the initial geometry relaxes. For quasi-equilibrium superposed Kerr-Schild (SKS) data [method (iii)], we construct initial data with \emph{initial} spins as large as 0.9997. We evolve SKS data sets with spins of 0.93 and 0.97 and find that the spin drops by only a few parts in 10^4 during the initial relaxation; therefore, we expect that SKS initial data will allow evolutions of binary black holes with relaxed spins above 0.99.

description: Retrospective studies have identified alcohol as a significant risk factor in drownings involving young adults. Few studies have explored this issue, therefore the current contextual understanding of alcohol consumption in aquatic settings is limited. This study used a survey (n = 182) and one-to-one and small group interviews (n = 23) to investigate knowledge and attitudes of United Kingdom and Australian young adults (aged 18–24 years) towards involvement in aquatic activity after consuming alcohol. Findings illustrated a poor level of general and aquatic-specific alcohol knowledge. Australian educated participants, and those self-reporting: stronger swimming competence; and/or completion of alcohol and water safety education; and/or participation in aquatic activity following alcohol consumption, achieved significantly higher knowledge scores. Most reported a neutral attitude, and those with previous experience of alcohol consumption in aquatic settings had more accepting attitudes of this behavior (p

description: We have investigated magnetically tunable Feshbach resonances in ultracold collisions of Rb with Yb in its metastable $^3$P$_2$ and $^3$P$_0$ states, using coupled-channel scattering and bound-state calculations. For the $^3$P$_2$ state, we find sharp resonances when both atoms are in their lowest Zeeman sublevels. However, these resonances are decayed by inelastic processes that produce Yb atoms in $^3$P$_1$ and $^3$P$_0$ states. The molecules that might be produced by magnetoassociation at the $^3$P$_2$ thresholds can decay by similar pathways and would have lifetimes no more than a few microseconds. For the $^3$P$_0$ state, by contrast, there are resonances that are promising for magnetoassociation. There are resonances due to both rotating and non-rotating molecular states that are significantly stronger than the analogous resonances for Yb($^1$S). The ones due to rotating states are denser in magnetic field; in contrast to Yb($^1$S), they exist even for bosonic isotopes of Yb($^3$P$_0$).

description: We estimate effective temperature ($T_{\rm eff}$), stellar radius, and luminosity for a sample of 271 M-dwarf stars (M0V-M7V) observed as a part of CARMENES (Calar Alto high-Resolution search for M dwarfs with Exo-earths with Near-infrared and optical Echelle Spectrographs) radial-velocity planet survey. For the first time, using the simultaneously observed high resolution (R$\sim90000$) spectra in the optical (0.52 - 0.96 $μ$m) and near-infrared (0.96 - 1.71 $μ$m) bands, we derive empirical calibration relationships to estimate the fundamental parameters of these low-mass stars. We select a sample of nearby and bright M-dwarfs as our calibrators for which the physical parameters are acquired from high-precision interferometric measurements. To identify the most suitable indicators of $T_{\rm eff}$, radius, and luminosity (log $L/L_{\odot}$), we inspect a range of spectral features and assess them for reliable correlations. We perform multivariate linear regression and find that the combination of pseudo equivalent widths and equivalent width ratios of the Ca II at 0.854 $μ$m and Ca II at 0.866 $μ$m lines in the optical and the Mg I line at 1.57 $μ$m in the NIR give the best fitting linear functional relations for the stellar parameters with root mean square errors (RMSE) of 99K, 0.06 $R_{\odot}$ and 0.22 dex respectively. We also explore and compare our results with literature values obtained using other different methods for the same sample of M dwarfs.

Radio kann unterhalten, informieren und entspannen. Nach außen wirkt es wie eine einfache Mischung aus Moderation und Musik, schaut man aber hinter die Kulissen dieses Mediums, sieht man die Komplexität des Programmaufbaus. Ein Zusammenspiel aus Moderation, Musik, Beiträgen und einem ganz wesentlichen, aber meist unterschätzen und unbeachteten Aspekt - dem Sound-Design. Das Sound-Design eines Radiosenders macht ihn zu dem, was er ist. Neben der Musikauswahl und der Art der Moderation ist das SoundDesign das Gesicht des Senders. Jeder kleinste eingespielte Ton, von Moderationsbetten über Jingles bis hin zum Sound-Effetk eines Kinderlachens, hat eine Auswirkung auf die Ausstrahlung eines Senders. Außerdem führt das SoundDesign dazu, dass Radio Bilder im Kopf der Hörer*innen erzeugen kann. 1 Sound-Design hat aber auch eine Funktion im Marketing eines Senders. Mit Erkennungsmelodien arbeiten Radiosender schon seit dem Anfang der 1920er-Jahre, um ihre Sender identifizierbar und einzigartig zu machen. Diese und andere Aspekte des Sound-Designs im Radio werden in der folgenden Forschung analysiert. Hierbei geht es hauptsächlich um die Art, mit welcher sich Radiosender an Hand ihrer Jingles, Einspieler und anderen Zwischensequenzen identifizieren und den Rezpient*innen somit als Marke im Gedächtnis bleiben und sie an diese binden. Der Forschungsgegenstand ist das Sound-Design des privaten Radiosenders radio SAW. Durch eigene Arbeitserfahrungen bei diesem Sender habe ich über deren ausgestrahltes Image, die Stimmung der Moderation und ihr Publikum ein gutes Vorwissen, Außerdem wurde für die Forschung ein fast uneingeschränkter Zugriff auf das aktuelle Archiv des Senders genehmigt, wodurch die Tonaufnahmen und Einspieler zugegriffen werden konnte.

The Burden of Chronic Kidney Disease: Risk Factors, Therapeutic Approaches, and Prevention
Creators: name: Zaman, Md
Publisher: name: Zenodo
Year: 2025

description: AbstractChronic kidney disease (CKD) is a progressive condition affecting millions worldwide, leading to significant morbidity, mortality, and a growing healthcare burden. Without timely intervention, CKD advances to end-stage renal disease (ESRD), necessitating dialysis or kidney transplantation, both of which are often costly and inaccessible, particularly in resource-limited settings. Early detection and effective management are critical in slowing disease progression and reducing associated complications. Individuals with diabetes and hypertension are at the highest risk and require routine kidney function monitoring. Pharmacological interventions, including angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and sodium-glucose cotransporter-2 (SGLT2) inhibitors, have demonstrated efficacy in delaying CKD progression and lowering cardiovascular risks. However, socioeconomic barriers, inadequate healthcare infrastructure, and high treatment costs remain significant obstacles to optimal CKD management, especially in low-income regions. In addition to medical therapy, lifestyle modifications such as smoking cessation, weight management, and strict glycemic and blood pressure control play a crucial role in preventing CKD onset and progression. Addressing these challenges requires a multidisciplinary approach that emphasizes early diagnosis, effective treatment, and equitable access to healthcare. Strengthening screening programs, improving the affordability of renoprotective therapies, and promoting preventive strategies are essential to mitigating the global burden of CKD.Keywords: Chronic kidney disease, CKD, ESRD, CKD complications, nephrotoxicity, dialysis, kidney transplant

description: We investigate the signatures of Fermi liquid formation in the N=4 super Yang-Mills theory coupled to fundamental hypermultiplet at nonvanishing chemical potential for the global U(1) vector symmetry. At strong 't Hooft coupling the system can be analyzed in terms of the D7 brane dynamics in AdS_5 x S^5 background. The phases with vanishing and finite charge density are separated at zero temperature by a quantum phase transition. In case of vanishing hypermultiplet mass, Karch, Son and Starinets discovered a gapless excitation whose speed equals the speed of sound. We find that this zero sound mode persists to all values of the hypermultiplet mass, and its speed vanishes at the point of phase transition. The value of critical exponent and the ratio of the velocities of zero and first sounds are consistent with the predictions of Landau Fermi liquid theory at strong coupling.

description: We have observed a Fermi-surface (FS) induced lattice modulation in a YBCO superconductor with a wavevector along CuO chains, {\it i.e.} ${\bf q}_1$=(0,$δ$,0). The value of $δ\sim0.21$ is twice the Fermi wavevector ($2{\bf k}_F$) along {\bf b*} connecting nearly nested FS `ridges'. The ${\bf q}_1$ modulation exists only within O-vacancy-ordered islands (characterized by ${\bf q}_0$=$(\frac14,0,0))$ and persists well above and below $T_c$. Our results are consistent with the presence of a FS-induced charge-density wave.
Effects of low temperature on K⁺ nutrition of some barley (Hordeum vulgare. L) varieties
Creators: name: De Silva, M. H. Mala Chandani
Publisher: name: University of British Columbia
Year: 2010

description: The main objective of the present study was to investigate the capacity to compensate for reduced root activity caused by low temperature. Potassium influx, net flux and tissue K⁺ content in 23 spring and 2 winter barley varieties grown at low (5°C) and high (15°C) root temperatures were studied. It was apparent that the rates of uptake (at low temperature) of low temperature grown winter and some spring varieties were adjusted in response to continuous low temperature so that absorption rates approached those of plants maintained at higher (15°C) temperature. The temperature sensitivity for influx varied among varieties depending on the growth temperature and internal K⁺ concentration. Halcyon, a winter variety, showed a low temperature sensitivity when grown at low temperature (5°C) and low external [KT] (0.005 mM). The acclimation potentials (the ratio of K⁺ influxes measured at the same temperature for the plants acclimated to different temperatures) were higher for winter varieties and some spring (e.g. Fergus) varieties, while most of the spring varieties exhibited a lower potential to acclimate. It was also apparent that acclimation of K⁺ uptake to low temperature could be achieved only if the external K⁺ supply was not limited. Growth rates of the whole plant, shoots and roots monitored over a short period (14 days) revealed differences in the partitioning of K⁺ under different temperatures (8° and 18°C) and at different nutrient (K4) regimes (0.1 mM and 0.005 mM) . Despite the reduction in growth rates, roots appeared to maintain a high K⁺ level when grown at low temperature. Nevertheless, such maintenance was possible only if the supply of K⁺ was adequate. A low external K⁺ content and low temperature reduced the acclimation capacity even in the winter variety, Halcyon. Therefore, the importance of K⁺ fertilization for plants to withstand cold temperatures is obvious. Net fluxes of Halcyon and Kombar (a variety bred for warm soils in California) were investigated over a period of 24 hours. Incomplete acclimation of net fluxes was observed for both varieties over that period. This revealed the importance of considering effluxes as well as influxes in determining acclimation. The amount of radioactivity (⁸⁶Rb) delivered to the shoot over a period of one hour was used to estimate the translocation rate. This was greater for the winter variety than in the spring variety. Growth temperature, and to a lesser extent the duration of exposure to low temperature, required for acclimation appeared to be the factors that determined acclimation. Halcyon seemed to acclimate much faster than Bonanza, a spring variety which showed only a very limited capacity of acclimation.

description: Farming faces a wider variety of risks in comparison with other economic sectors, and the systemic nature of agricultural risks induce farmers to seek government intervention. In the EU, public interventions supporting agricultural risk management are contained in the Risk Management Toolkit (RMT) of the Common Agricultural Policy (CAP), which is a voluntary policy adopted by less than half of the EU Member States. We focus in particular on Measure 5 on “Restoring agricultural production potential damaged by natural disasters and catastrophic events and introduction of appropriate prevention actions” and Measure 17 on “Risk management” of the CAP’s Rural Development policy. In order to understand the relatively low adoption of the RMT, this paper investigates the drivers of EU regions’ expenditure towards the RMT by applying and comparing four types of regional-level spatial models, namely a spatial error model, a spatial autoregressive model, a spatial lag of X model and a spatial Durbin error model.

description: The recently developed tensor renormalization-group (TRG) method provides a highly precise technique for deriving thermodynamic and critical properties of lattice Hamiltonians. The TRG is a local coarse-graining transformation, with the elements of the tensor at each lattice site playing the part of the interactions that undergo the renormalization-group flows. These tensor flows are directly related to the phase diagram structure of the infinite system, with each phase flowing to a distinct surface of fixed points. Fixed-point analysis and summation along the flows give the critical exponents, as well as thermodynamic functions along the entire temperature range. Thus, for the ferromagnetic triangular lattice Ising model, the free energy is calculated to better than 10^-5 along the entire temperature range. Unlike previous position-space renormalization-group methods, the truncation (of the tensor index range D) in this general method converges under straightforward and systematic improvements. Our best results are easily obtained with D = 24, corresponding to 4624-dimensional renormalization-group flows.

description: The topological structure of basin boundaries plays a fundamental role in the sensitivity to the initial conditions in chaotic dynamical systems. Herewith we present a study on the dynamics of dissipative systems close to the Hamiltonian limit, emphasising the increasing number of periodic attractors and on the structural changes in their basin boundaries as the dissipation approaches zero. We show numerically that a power law with nontrivial exponent describes the growth of the total number of periodic attractors as the damping is decreased. We also establish that for small scales the dynamics is governed by \emph{effective} dynamical invariants, whose measure depends not only on the region of the phase space, but also on the scale under consideration. Therefore, our results show that the concept of effective invariants is also relevant for dissipative systems.

description: Anomalous dimensions of high-twist Wilson operators have a nontrivial scaling behavior in the limit when their Lorentz spin grows exponentially with the twist. To describe the corresponding scaling function in planar N=4 SYM theory, we analyze an integral equation recently proposed by Freyhult, Rej and Staudacher and argue that at strong coupling it can be casted into a form identical to the thermodynamical Bethe Ansatz equations for the nonlinear O(6) sigma model. This result is in a perfect agreement with the proposal put forward by Alday and Maldacena within the dual string description, that the scaling function should coincide with the energy density of the nonlinear O(6) sigma model embedded into AdS_5xS^5.

description: The very first infected novel coronavirus case (COVID-19) was found in Hubei, China in Dec. 2019. The COVID-19 pandemic has spread over 214 countries and areas in the world, and has significantly affected every aspect of our daily lives. At the time of writing this article, the numbers of infected cases and deaths still increase significantly and have no sign of a well-controlled situation, e.g., as of 13 July 2020, from a total number of around 13.1 million positive cases, 571, 527 deaths were reported in the world. Motivated by recent advances and applications of artificial intelligence (AI) and big data in various areas, this paper aims at emphasizing their importance in responding to the COVID-19 outbreak and preventing the severe effects of the COVID-19 pandemic. We firstly present an overview of AI and big data, then identify the applications aimed at fighting against COVID-19, next highlight challenges and issues associated with state-of-the-art solutions, and finally come up with recommendations for the communications to effectively control the COVID-19 situation. It is expected that this paper provides researchers and communities with new insights into the ways AI and big data improve the COVID-19 situation, and drives further studies in stopping the COVID-19 outbreak.

description: The color matrix elements of the ghost triangle diagram that appears in the triple gluon vertex and the ghost-ghost-gluon triangle diagram that appears in the ghost-gluon-ghost vertex are calculated. The ghost-ghost-gluon triangle contains a loop consisting of two color diagonal ghosts and one gluon and a loop consisting of two color antisymmetric ghosts and one gluon. Consequently, the pQCD argument in the infrared region based on the one particle irreducible diagram should be modified. Implications for the Kugo-Ojima color confinement and the QCD running coupling are discussed.

description: We have investigated the magnetoelectric coupling in the lone pair containing piezoelectric ferrimagnet Cu2OSeO3. Significant magnetocapacitance develops in the magnetically ordered state (TC = 60 K). We find critical behavior near TC and a divergence near the metamagnetic transition at 500 Oe. High-resolution X-ray and neutron powder diffraction measurements show that Cu2OSeO3 is metrically cubic down to 10 K but that the ferrimagnetic ordering reduces the symmetry to rhombohedral R3. The metric cubic lattice dimensions exclude a magnetoelectric coupling mechanism involving spontaneous lattice strain, and this is unique among magnetoelectric and multiferroic materials.

description: This article deals with the development of an interactive up-to-date Pacific Islands Web GIS Atlas. It focuses on the compilation of spatial data from the twelve member countries of the University of the South Pacific (Cook Islands, Fiji Islands, Kiribati Islands, Marshall Islands, Nauru, Niue, Tonga, Tuvalu, Tokelau, Solomon Islands, Vanuatu, and Western Samoa). A previous bitmap web Atlas was created in 1996, and was a pilot activity investigating the potential for using Geographical Information Systems (GIS) in the South Pacific. The objective of the new atlas is to provide sets of spatial and attributive data and maps for use of educators, students, researchers, policy makers and other relevant user groups and the public. GIS is a highly flexible and dynamic technology that allows the construction and analysis of maps and data sets from a variety of sources and formats. Nowadays, GIS application has moved from local and client-server applications to a three-tier architecture: Client (Web Browser) -- Application Web Map Server -- Spatial Data Warehouses. The objective of this project is to produce an Atlas that will include interactive maps and data on an Application Web Map Server. Intergraph products such as GeoMedia Professional, Web Map and Web Publisher have been selected for the web atlas production and design. In an interactive environment, an atlas will be composed from a series of maps and data profiles, which will be based on legend entries, queries, hot spots and cartographic tools. Only the first stage of development of the atlas and related technological solutions are outlined in this article.

description: We present detailed Fourier modeling of the radio remnant of Supernova 1987A, using high-resolution 9 GHz and 18 GHz data taken with the Australia Telescope Compact Array over the period 1992 to 2008. We develop a parameterized three-dimensional torus model for the expanding radio shell, in which the emission is confined to an inclined equatorial belt; our model also incorporates both a correction for light travel-time effects and an overall east-west gradient in the radio emissivity. By deriving an analytic expression for the two-dimensional Fourier transform of the projected three-dimensional brightness distribution, we can fit our spatial model directly to the interferometric visibility data. This provides robust estimates to the radio morphology at each epoch. The best-fit results suggest a constant remnant expansion at 4000 +/- 400 km/s over the 16-year period covered by the observations. The model fits also indicate substantial mid-latitude emission, extending to 40 degree on either side of the equatorial plane. This likely corresponds to the extra-planar structure seen in H$α$ and Ly$α$ emission from the supernova reverse shock, and broadly supports hydrodynamic models in which the complex circumstellar environment was produced by a progression of interacting winds from the progenitor. Our model quantifies the clear asymmetry seen in the radio images: we find that the eastern half of the radio remnant is consistently ~40 brighter than the western half at all epochs, which may result from an asymmetry in the ejecta distribution between these two hemispheres.
