description: We conducted phase referencing VLBI observations of the Mira variable T~Lepus (T~Lep) using VERA, from 2003 to 2006. The distance to the source was determined from its annual parallax which was measured to be 3.06$\pm$0.04 mas, corresponding to a distance of 327$\pm$4\,pc. Our observations revealed the distribution and internal kinematics of H$_2$O masers in T~Lep, and we derived a source systemic motions of 14.60$\pm$0.50 mas yr$^{-1}$ and $-$35.43$\pm$0.79 mas yr$^{-1}$ in right ascension and declination, respectively. We also determined a LSR velocity of $V_\mathrm{LSR}^{\ast} = -$27.63 km s$^{-1}$. Comparison of our result with an image recently obtained from the VLTI infrared interferometer reveals a linear scale picture of the circumstellar structure of T~Lep. Analysis of the source systemic motion in the Galacto-centric coordinate frame indicates a large peculiar motion, which is consistent with the general characteristics of AGB stars. This source makes a contribution to the calibration of the period-luminosity relation of Galactic Mira variables. From the compilation of data for nearby Mira variables found in the literature, whose distances were derived from astrometric VLBI observations, we have calibrated the Galactic Mira period-luminosity relation to a high degree of accuracy.

description: Recent experiments demonstrated that proton transport through graphene electrodes can be accelerated by over an order of magnitude with low intensity illumination. Here we show that this photo-effect can be suppressed for a tuneable fraction of the infrared spectrum by applying a voltage bias. Using photocurrent measurements and Raman spectroscopy, we show that such fraction can be selected by tuning the Fermi energy of electrons in graphene with a bias, a phenomenon controlled by Pauli blocking of photo-excited electrons. These findings demonstrate a dependence between graphene's electronic and proton transport properties and provide fundamental insights into molecularly thin electrode-electrolyte interfaces and their interaction with light.

Cosmological Solutions of Chameleon Scalar Field Model

description: We investigate cosmological solutions of the chameleon model with a non-minimal coupling between the matter and the scalar field through a conformal factor with gravitational strength. By considering the spatially flat FLRW metric and the matter density as a non-relativistic perfect fluid, we focus on the matter-dominated phase and the late-time accelerated phase of the universe. In this regard, we manipulate and scrutinize the related field equations for the density parameters of the matter and the scalar fields with respect to the e-folding. Since the scalar field fluctuations depend on the background and the field equations become highly non-linear, we probe and derive the governing equations in the context of various cases of the relation between the kinetic and potential energies of the chameleon scalar field, or indeed, for some specific cases of the scalar field equation of state parameter. Thereupon, we schematically plot those density parameters for two different values of the chameleon non-minimal coupling parameter, and discuss the results. In both considered phases, we specify that, when the kinetic energy of the chameleon scalar field is much less than its potential energy (i.e., when the scalar field equation of state parameter is $\simeq - 1 $), the behavior of the chameleon model is similar to the $ΛCDM$ model. Such compatibility suggests that the chameleon model is phenomenologically viable and can be tested with the observational data.

description: The self-consistent rate theory for surface growth in the submonolayer regime is generalized from mono- to multi-component systems, which are formed by codeposition of different types of atoms or molecules. As a new feature, the theory requires the introduction of pair density distributions to enable a symmetric treatment of reactions among different species. The approach is explicitly developed for binary systems and tested against kinetic Monte Carlo simulations. Using a reduced set of rate equations, only a few differential equations need to be solved to obtain good quantitative predictions for island and adatom densities, as well as densities of unstable clusters.

description: We apply a recently developed approach (Liaw 2013) to study the existence of extended states for the three dimensional discrete random Schroedinger operator at small disorder. The conclusion of delocalization at small disorder agrees with other numerical and experimental observations. Further the work furnishes a verification of the numerical approach and its implementation. Not being based on scaling theory, this method eliminates problems due to boundary conditions, common to previous numerical methods in the field. At the same time, as with any numerical experiment, one cannot exclude finite-size effects with complete certainty. Our work can be thought of as a new and quite different use of Lanczos' algorithm; a posteriori tests to show that the orthogonality loss is very small. We numerically track the "bulk distribution" (here: the distribution of where we most likely find an electron) of a wave packet initially located at the origin, after iterative application of the discrete random Schroedinger operator.

An Analytic Model for Buoyancy Resonances in Protoplanetary Disks

description: Zhu, Stone, and Rafikov (2012) found in 3D shearing box simulations a new form of planet-disk interaction that they attributed to a vertical buoyancy resonance in the disk. We describe an analytic linear model for this interaction. We adopt a simplified model involving azimuthal forcing that produces the resonance and permits an analytic description of its structure. We derive an analytic expression for the buoyancy torque and show that the vertical torque distribution agrees well with results of Athena simulations and a Fourier method for linear numerical calculations carried out with the same forcing. The buoyancy resonance differs from the classic Lindblad and corotation resonances in that the resonance lies along tilted planes. Its width depends on damping effects and is independent of the gas sound speed. The resonance does not excite propagating waves. At a given large azimuthal wavenumber k_y > 1/h (for disk thickness h), the buoyancy resonance exerts a torque over a region that lies radially closer to the corotation radius than the Lindblad resonance. Because the torque is localized to the region of excitation, it is potentially subject to the effects of nonlinear saturation. In addition, the torque can be reduced by the effects of radiative heat transfer between the resonant region and its surroundings. For each azimuthal wavenumber, the resonance establishes a large scale density wave pattern in a plane within the disk.

description: A precise characterisation of the red giants in the seismology fields of the CoRoT satellite is a prerequisite for further in-depth seismic modelling. High-resolution FEROS and HARPS spectra were obtained as part of the ground-based follow-up campaigns for 19 targets holding great asteroseismic potential. These data are used to accurately estimate their fundamental parameters and the abundances of 16 chemical species in a self-consistent manner. Some powerful probes of mixing are investigated (the Li and CNO abundances, as well as the carbon isotopic ratio in a few cases). The information provided by the spectroscopic and seismic data is combined to provide more accurate physical parameters and abundances. The stars in our sample follow the general abundance trends as a function of the metallicity observed in stars of the Galactic disk. After an allowance is made for the chemical evolution of the interstellar medium, the observational signature of internal mixing phenomena is revealed through the detection at the stellar surface of the products of the CN cycle. A contamination by NeNa-cycled material in the most massive stars is also discussed. With the asteroseismic constraints, these data will pave the way for a detailed theoretical investigation of the physical processes responsible for the transport of chemical elements in evolved, low- and intermediate-mass stars.

description: Software-defined satellite-terrestrial integrated networks (SDSTNs) are seen as a promising paradigm for achieving high resource flexibility and global communication coverage. However, low latency service provisioning is still challenging due to the fast variation of network topology and limited onboard resource at low earth orbit satellites. To address this issue, we study service provisioning in SDSTNs via joint optimization of virtual network function (VNF) placement and routing planning with network dynamics characterized by a time-evolving graph. Aiming at minimizing average service latency, the corresponding problem is formulated as an integer nonlinear programming under resource, VNF deployment, and time-slotted flow constraints. Since exhaustive search is intractable, we transform the primary problem into an integer linear programming by involving auxiliary variables and then propose a Benders decomposition based branch-and-cut (BDBC) algorithm. Towards practical use, a time expansion-based decoupled greedy (TEDG) algorithm is further designed with rigorous complexity analysis. Extensive experiments demonstrate the optimality of BDBC algorithm and the low complexity of TEDG algorithm. Meanwhile, it is indicated that they can improve the number of completed services within a configuration period by up to 58% and reduce the average service latency by up to 17% compared to baseline schemes.

description: Understanding the spread of SARS-CoV-2 has been one of the most pressing problems of the recent past. Network models present a potent approach to studying such spreading phenomena because of their ability to represent complex social interactions. While previous studies have shown that network centrality measures are generally able to identify influential spreaders in a susceptible population, it is not yet known if they can also be used to predict infection risks. However, information about infection risks at the individual level is vital for the design of targeted interventions. Here, we use large-scale administrative data from the Netherlands to study whether centrality measures can predict the risk and timing of infections with COVID-19-like diseases. We investigate this issue leveraging the framework of multi-layer networks, which accounts for interactions taking place in different contexts, such as workplaces, households and schools. In epidemic models simulated on real-world network data from over one million individuals, we find that existing centrality measures offer good predictions of relative infection risks, and are correlated with the timing of individual infections. We however find no association between centrality measures and real SARS-CoV-2 test data, which indicates that population-scale network data alone cannot aid predictions of virus transmission.

description: Aim: This study aimed to estimate the prevalence, to characterize, and to evaluate antimicrobial susceptibility of pathogenic E. coli and Salmonella spp. in stray cats and dogs. Methods: Between November 2019 and October 2020, 199 faecal samples were obtained from 102 cats and 97 dogs rescued by a kennel in Lisboa. Isolation was performed in selective and non-selective medium, followed by identification of virulence genes of E. coli by PCR, and Salmonella serotyping. Antimicrobial susceptibility testing (AST) was performed according to EUCAST. mcr-1-5 genes were detected by PCR. All pathogenic isolates were further characterized by WGS. Results: The overall rate of E.coli and Salmonella was 73.9% (147/199) and 0.5% (1/199), respectively. Pathogenic E. coli were detected in 19.6% dogs and 18.6% cats. No cases of STEC were found. AST revealed that 13.0% of the isolates were resistant (16.2% dogs vs. 10.0% cats). Resistance to ampicillin, tetracycline, sulfamethoxazole, and/or trimethoprim were the most frequent. MDR was observed in four ETEC isolated from dogs, which have the same ST155 and blaTEM-1B, sul1, sul2, dfrA1, and tet(A) resistance genes. All commensal E. coli were susceptible to antimicrobials. Salmonella (S.4,5:i:-) was identified in a cat. Belongs to ST3478 and presents ac(6')-Iaa, blaTEM-1B, and sul2 resistance genes. None isolate was ESBL or harboured mcr genes. Conclusions: Some of the isolates have relevant antimicrobial resistance. Due to the close contact with humans and to the potential release of pathogenic and resistant enteric bacteria in the environment, it is important to monitor stray cats and dogs health status following a One Health approach.

description: We present a mapping algorithm to compute large-scale magnetic field maps in indoor environments with approximate Gaussian process (GP) regression. Mapping the spatial variations in the ambient magnetic field can be used for localization algorithms in indoor areas. To compute such a map, GP regression is a suitable tool because it provides predictions of the magnetic field at new locations along with uncertainty quantification. Because full GP regression has a complexity that grows cubically with the number of data points, approximations for GPs have been extensively studied. In this paper, we build on the structured kernel interpolation (SKI) framework, speeding up inference by exploiting efficient Krylov subspace methods. More specifically, we incorporate SKI with derivatives (D-SKI) into the scalar potential model for magnetic field modeling and compute both predictive mean and covariance with a complexity that is linear in the data points. In our simulations, we show that our method achieves better accuracy than current state-of-the-art methods on magnetic field maps with a growing mapping area. In our large-scale experiments, we construct magnetic field maps from up to 40000 three-dimensional magnetic field measurements in less than two minutes on a standard laptop.
Fine-grained Patches for Java Software Upgrades

Publisher: name: arXiv
Year: 2014

description: We present a novel methodology for deriving fine-grained patches of Java software. We consider an abstract-syntax tree (AST) representation of Java classes compiled to the Java Virtual Machine (JVM) format, and a difference analysis over the AST representation to derive patches. The AST representation defines an appropriate abstraction level for analyzing differences, yielding compact patches that correlate modularly to actual source code changes. The approach contrasts to other common, coarse-grained approaches, like plain binary differences, which may easily lead to disproportionately large patches. We present the main traits of the methodology, a prototype tool called aspa that implements it, and a case-study analysis on the use of aspa to derive patches for the Java 2 SE API. The case-study results illustrate that aspa patches have a significantly smaller size than patches derived by binary differencing tools.

Aïoli platform

description: Archaeologists, architects, engineers, materials specialists, curators and restorers of cultural property, teachers, students, tourists, contribute to the daily knowledge and conservation of heritage artefacts. The need to identify a stable common denominator was born from the heterogeneous data produced by those observations. It is the starting point for the development of Aïoli, an application that puts the heritage artefacts at the heart of the process.
 Each user is thus able to directly annotate the object, whether it is a site, a building, a sculpture, a painting, a work of art, or an archaeological fragment, to the benefit of their peers. This approach creates a bridge between the object and the information produced by a given community, thus creating a kind of “digital epidermis”.
 The platform also enables a multi-temporal analysis, in order to allow a follow-up on the state of its conservation and possible degradation. From simple photographs, the application generates a 3D representation of the object, which can directly be enriched with semantic annotations or additional resources related to the object (texts, images, videos, sounds. . .).
 This service is based on two major technological developments: the democratization of photogrammetry techniques, which allow us to compute a 3D model by correlation of images, and the possibility of massively processing and sharing gathered data through the cloud. This cloud computing performance is linked to a specific development for multidimensional propagation of spatial semantic annotations. Through this propagation process, annotations are automatically reprojected on all the 2D and 3D views of the object (past, present, and future).
 This tool, which is anchored in the development of citizen science, aims to create new methodologies for multidisciplinary work, and to put forward new scenarios of comparative and cooperative analysis of heritage objects.

description: Living organisms have to adjust to their surrounding in order to survive in stressful conditions. We study this mechanism in one of most primitive creatures - photosynthetic green sulfur bacteria. These bacteria absorb photons very efficiently using the chlorosome antenna complexes and perform photosynthesis in extreme low-light environments. How the chlorosomes in green sulfur bacteria are acclimated to the stressful light conditions, for instance, if the spectrum of light is not optimal for absorption, is unknown. Studying Chlorobaculum tepidum cultures with far-red to near-infrared light-emitting diodes, we found that these bacteria react to changes in energy flow by regulating the amount of light-absorbing pigments and the size of the chlorosomes. Surprisingly, our results indicate that the bacteria can survive in near-infrared lights capturing low-frequency photons by the intermediate units of the light-harvesting complex. The latter strategy may be used by the species recently found near hydrothermal vents in the Pacific Ocean.

Subjects: subject: Differential Geometry (math.DG)

description: Locally stable maps $S^3\to\mathbb{R}^4$ are classified up to homotopy through locally stable maps. The equivalence class of a map $f$ is determined by three invariants: the isotopy class $σ(f)$ of its framed singularity link, the generalized normal degree $ν(f)$, and the algebraic number of cusps $κ(f)$ of any extension of $f$ to a locally stable map of the $4$-disk into $\mathbb{R}^5$. Relations between the invariants are described, and it is proved that for any $σ$, $ν$, and $κ$ which satisfy these relations, there exists a map $f:S^3\to\mathbb{R}^4$ with $σ(f)=σ$, $ν(f)=ν$, and $κ(f)=κ$. It follows in particular that every framed link in $S^3$ is the singularity set of some locally stable map into $\mathbb{R}^4$.

description: Saltpans are increasingly being abandoned around the world, leading to the loss of ecosystem services provided by these unique semi-natural wetlands. The desertion of a saltpan at the Swartkops Estuary, South Africa has left behind a large area of desiccated hypersaline sediment and a sharp decrease in waterbird abundance and diversity. Here, we explore the potential for restoring this saltpan’s wetland function using stormwater inflow to support multiple ecosystem services and improve estuary health. Stormwater will be able to flow into the saltpan as a passive restoration approach that can maintain the site as a wetland habitat. This will contribute to improving the health of a nationally important, yet highly degraded, estuary by retaining 758 ML of stormwater to achieve full capacity, containing an estimated 2908 kg of dissolved inorganic nitrogen and 68 kg of dissolved inorganic nitrogen. Additional ecosystem services such as biodiversity maintenance, carbon storage and societal values can be expected. However, this would create a novel hypersaline stormwater wetland and a strategic adaptive management approach will be required. Management must be guided by monitoring, which should comprise collection of basic environmental data to establish a baseline condition, and against which, long term changes and responses resulting from stochastic events can be assessed and mitigated through the use of achievable ecological restoration targets.

description: Ndumo Game Reserve (NGR), a Ramsar site, situated in South Africa’s largest floodplain (Phongolo River floodplain) in northern KwaZulu-Natal, with important aquatic ecosystems: the Usuthu and Phongolo rivers and their associated floodplain lakes. While the Phongolo River is regulated, the Usuthu River is unregulated and subjected to fewer anthropogenic activities that influence the downstream environmental quality of this Ramsar system. The present study evaluates the environmental quality of floodplain systems in the NGR. Water and sediment were sampled and analysed from both rivers and associated floodplain lakes during different hydrological periods (flow). Using multivariate statistical techniques, ionic compositions, as well as water and sediment quality indices of the ecosystems were evaluated. Key findings suggest spatial and flow-related differences, which highlight the human-driven impacts from the upper catchments and the rivers influence on their respective floodplain lakes. The environmental quality (water and sediments) could be classified as ‘good’ and predominantly unimpacted. Notably, ionic composition of river water showed the importance of the unregulated Usuthu River and its contribution to aquatic ecosystems within the NGR and their continued functioning. The quality indices further indicated that metals do not currently pose any ecological risks to these systems.

description: We present a detailed electronic structure study of the non-centrosymmetric superconductor BiPd based on our angle resolved photoemission spectroscopy (ARPES) measurements and Density Functional Theory (DFT) based calculations. We observe a high intensity distribution on the Fermi surface (FS) of this compound resulting from various electron and hole like bands which are present in the vicinity of the Fermi energy (E$_f$). The near E$_f$ states are primarily composed of Bi-6p with a little admixture of Pd-4d$_{x^2-y^2/zy}$ orbitals. There are various spin-orbit split bands involved in the crossing of E$_f$ making a complex FS. The FS mainly consists of multi sheets of three dimensions which disfavor the nesting between different sheets of the FS. Our comprehensive study elucidates that BiPd could be a s-wave multiband superconductor.

description: In this paper I present dynamic models of the radio source Centaurus A, and critique possible models of in situ particle reacceleration (ISR) within the radio lobes. The radio and gamma-ray data require neither homogeneous plasma nor quasi-equipartition between plasma and magnetic field; inhomogeneous models containing both high-field and low-field regions are equally likely. Cen A cannot be as young as the radiative lifetimes of its relativistic electrons, which range from a few to several tens of Myr. Two classes of dynamic models -- flow driven and magnetically driven -- are consistent with current observations; each requires Cen A to be on the order of a Gyr old. Thus, ongoing ISR must be occurring within the radio source. Alfven-wave ISR is probably occurring throughout the source, and may be responsible for maintaining the gamma-ray-loud electrons. It is likely to be supplemented by shock or reconnection ISR which maintains the radio-loud electrons in high-field regions.

description: Koivut ovat tärkeitä boreaalisen vyöhykkeen pioneerilajeja. Ne ovat kesävihantia, tuulipölytteisiä ja yksikotisia ja niiden runsas siemensato leviää hyvin tuulen mukana. Suvussa on yli 60 lajia (määrä vaihtelee eri lähteiden mukaan aina 120 asti). Betula pendula (rauduskoivu) ja B pubescens (hieskoivu) kasvavat lähes koko Euroopassa sekä Aasian pohjoisosassa (Hämet-Ahti ym., 1989, Niemistö ym., 2008). B. alleghaniensis (keltakoivu), B. lenta (sokerikoivu), B. papyrifera (paperikoivu), B. populifolia (poppelikoivu) ja B. nigra (mustakoivu) ovat tavallisia koivulajeja Pohjois-Amerikassa (Hämet-Ahti ym., 1989; Verkasalo, 1990). Varsinkin pohjoismaissa B. pendula on tärkeä puulaji sekä vaneri- että sahateollisuudelle, mutta sitä käytetään myös yleisesti puisto- ja pihapuina. Samoin B. alleghaniensis, B. lenta ja B. papyrifera ovat lajeja, joita kasvatetaan teollisuuden tarpeiksi. Koivut kestävät hyvin kylmyyttä ja Keski-Euroopassa ne kasvavat usein vuoristoalueilla. Monet koivulajit kuten B. nana (vaivaiskoivu), B. pubescens subsp. czerepanovii (tunturikoivu) ja B. utilis (himalajankoivu) ovat tyypillisiä metsärajapuita. B. nana kasvaa pensaana tai varpuna pohjoisilla alueilla ollen esiintymiseltään maailman pohjoisin koivulaji. Alalaji B. nana subsp. nana kasvaa lähinnä Pohjois Euroopassa ja Venäjällä, sekä muun muassa Grönlannissa ja Huippuvuorilla. Vaivaiskoivu ja sen alalaji kasvavat Yhdysvaltojen pohjoisosissa ja Koillis-Aasiassa, ja niiden eteläisimmät esiintymisalueet ovat vuoristossa muun muassa Skotlannissa ja Alpeilla. B. utilis puolestaan kasvaa sekä puuna että pensaana ja on kotoisin Himalajalta (Hämet-Ahti ym., 1989; http://www.discoverlife.org).

description: Accretion disks are ubiquitous in the universe and it is generally accepted that magnetic fields play a pivotal role in accretion-disk physics. The spin history of millisecond pulsars, which are usually classified as magnetized neutron stars spun up by an accretion disk, depends sensitively on the magnetic field structure, and yet highly idealized models from the 80s are still being used for calculating the magnetic field components. We present a possible way of improving the currently used models with a semi-analytic approach. The resulting magnetic field profile of both the poloidal and the toroidal component can be very different from the one suggested previously. This might dramatically change our picture of which parts of the disk tend to spin the star up or down.

description: We are interested in the "almost" global-in-time existence of classical solutions in the general theory for nonlinear wave equations. All the three such cases are known to be sharp due to blow-up results in the critical case for model equations. However, it is known that we have a possibility to get the global-in-time existence for two of them in low space dimensions if the nonlinear term is of derivatives of the unknown function and satisfies so-called null condition, or non-positive condition. But another one for the quadratic term in four space dimensions is out of the case as the nonlinear term should include a square of the unknown function itself. In this paper, we get one more example guaranteeing the sharpness of the almost global-in-time existence in four space dimensions. It is also the first example of the blow-up of classical solutions for non-single and indefinitely signed term in high dimensions. Such a term arises from the neglect of derivative-loss factors in Duhamel's formula for positive and single nonlinear term. This fact may help us to describe a criterion to get the global-in-time existence in this critical situation.

It is based on 38 key informant interviews conducted in 2022 and 2023 with stakeholders in Cox’s Bazar and a review of relevant literature. This brief summarizes the sources of education system (in)coherences in Cox’s Bazar, drawing out the links between sector operations and the key actors’ de facto incentives and capacities, and illustrates the value of understanding how these political economy drivers shape the contours of plausible reforms to improve education coherence in emergencies.

description: Perturbative corrections to the Casimir free energy due to macroscopic roughness of dielectric interfaces are obtained in the framework of an effective low-energy field theory. It describes the interaction of electromagnetic fields with materials whose plasma frequency $ω_p$ determines the low-energy scale. The naïve perturbative expansion of the single-interface scattering matrix in the variance of the profile is sensitive to short wavelength components of the roughness correlation function. We introduce generalized counter terms that subtract and correct these high-momentum contributions to the loop expansion. To leading order the counter terms are determined by the phenomenological plasmon model. The latter is found to be consistent with the low-energy description. The proximity force approximation is recovered in the limit of long correlation length and gives the upper limit for the roughness correction to the Casimir force. The renormalized low-energy theory is insensitive to the high-momentum behavior of the roughness correlation function. Predictions of the improved theory are compared with those of the unrenormalized model and with experiment. The Casimir interaction of interfaces with low levels of roughness is found to be well reproduced by that of flat parallel plates with the measured reflection coefficients at a distance that is slightly less than the mean separation of the rough surfaces.

description: In light of a recent direct experimental confirmation of a Lorentz contraction of Coulomb field (an electric field of a point charge in a uniform motion), we revisit some common confusions related to it, to be mindful of in teaching the subject. These include the questions about a radial nature of the field, a role of the retardation effect due to a finite speed of information transfer and some issues related to a depiction of Coulomb field by means of the Lorentz contracted field lines.
