description: Aims Persistence plays a key role in both plant population and community dynamics as it allows withstanding temporarily habitat conditions unsuitable for growth and reproduction. Plants can exploit three different strategies to persist in situ (building soil seed banks, increasing adult longevity and/or clonal reproduction), the dominance of which in a community might vary along environmental gradients. Yet, their relative role in plant persistence has never been investigated. Location The Bavarian Alps, Germany. Methods We collected data on seed soil persistence, adult longevity and clonality for 290 species occurring in 18 grasslands located along an elevational gradient of 1,000 metres and examined their contribution to persistence in a community. Linear models were used to estimate the relationship between elevation and these persistence strategies. Results We found that dominance of a certain persistence strategy varied depending on environmental variability. Specifically, persistence in lowlands was mainly achieved by persistent and dense soil seed banks along with extended clonal growth (larger spread distances and higher number of offspring). Contrastingly, the main persistence strategy in the alpine communities was increased adult longevity. Conclusions The changes in relative contribution of each strategy to community persistence along the elevational gradient are interrelated suggesting a trade-off among them. We conclude that this trade-off plays an important role in species co-existence and community assembly, and might be useful to understand vegetation dynamics under ongoing climate change and improve restoration efforts of upland ecosystems.

description: In this lecture note, we introduce the basic concepts of game theory (GT), a branch of mathematics traditionally studied and applied in the areas of economics, political science, and biology, which has emerged in the last fifteen years as an effective framework for communications, networking, and signal processing (SP). The real catalyzer has been the blooming of all issues related to distributed networks, in which the nodes can be modeled as players in a game competing for system resources. Some relevant notions of GT are introduced by elaborating on a simple application in the context of wireless communications, notably the power control in an interference channel (IC) with two transmitters and two receivers.

description: We study how the encasement of a growing elastic bulk within a possibly differently growing elastic coat may induce mechanical instabilities in the equilibrium shape of the combined body. The inhomogeneities induced in an incompressible bulk during growth are also discussed. These effects are illustrated through a simple example in which a growing elastic cylinder may undergo a shape transition towards a bent configuration.

description: The LANDMAP project has produced orthoimages which have been geocoded with a DEM derived from Interferometric SAR. A mosaic of the whole of the UK will be available once the project is finished. The DEM will also be used to create orthoimage mosaics from SPOT and Landsat images. These datasets will all be validated to assess their planimetric quality. As there are large amounts of data involved and problems in identifying ground control points, automatic methods are desirable. This paper discusses the reference data available and methods used for the validation. At the time of writing only preliminary results were available.

description: We consider finite element discretizations of the Biot's consolidation model in poroelasticity with MINI and stabilized P1-P1 elements. We analyze the convergence of the fully discrete model based on spatial discretization with these types of finite elements and implicit Euler method in time. We also address the issue related to the presence of non-physical oscillations in the pressure approximation for low permeabilities and/or small time steps. We show that even in 1D a Stokes-stable finite element pair fails to provide a monotone discretization for the pressure in such regimes. We then introduce a stabilization term which removes the oscillations. We present numerical results confirming the monotone behavior of the stabilized schemes.

description: Monte Carlo simulations of mono-- and polydisperse two--dimensional crystals are reported. The particles in the studied system, interacting through hard--core repulsive Yukawa potential, form a solid phase of hexagonal lattice. The elastic properties of crystalline Yukawa systems are determined in the $NpT$ ensemble with variable shape of the periodic box. Effects of the Debye screening length ($κ^{-1}$), contact value of the potential ($ε$), and the size polydispersity of particles on elastic properties of the system are studied. The simulations show that the polydispersity of particles strongly influences the elastic properties of the studied system, especially on the shear modulus. It is also found that the elastic moduli increase with density and their growth rate depends on the screening length. Shorter screening length leads to faster increase of elastic moduli with density and decrease of the Poisson's ratio. In contrast to its three-dimensional version, the studied system is non-auxetic, i.e. shows positive Poisson's ratio.

description: Using all-sky maps obtained from COBE/DIRBE at 3.5 and 4.9 um, we present a reanalysis of diffuse sky emissions such as zodiacal light (ZL), diffuse Galactic light (DGL), integrated starlight (ISL), and isotropic residual emission including the extragalactic background light (EBL). Our new analysis, which includes an improved estimate of ISL using the Wide-field Infrared Survey Explorer (WISE) data, enabled us to find the DGL signal in a direct linear correlation between diffuse near-infrared and 100 um emission at high Galactic latitudes (|b| > 35 degree). At 3.5um, the high-latitude DGL result is comparable to the low-latitude value derived from the previous DIRBE analysis. In comparison with models of the DGL spectrum assuming a size distribution of dust grains composed of amorphous silicate, graphite, and polycyclic aromatic hydrocarbon (PAH), the measured DGL values at 3.5 and 4.9 um constrain the mass fraction of PAH particles in the total dust species to be more than ~ 2%. This was consistent with the results of Spitzer/IRAC toward the lower Galactic latitude regions. The derived residual emission of 8.9 +/- 3.4 nW m^{-2} sr^{-1} at 3.5 um is marginally consistent with the level of integrated galaxy light and the EBL constraints from the gamma-ray observations. The residual emission at 4.9 um is not significantly detected due to the large uncertainty in the ZL subtraction, same as previous studies. Combined with our reanalysis of the DIRBE data at 1.25 and 2.2 um, the residual emission in the near-infrared exhibits the Rayleigh-Jeans spectrum.

Various authors have therefore rejected Aellen’s choice as having been ineligible (i.e. not original material for the name), and most have followed a neotypification by Townsend (in Nasir & Ali, Fl. W. Pakistan 71: 17. 1974). However, Linnaeus’ third synonym is an account by Bauhin and Cherler, accompanied by an illustration. While Linnaeus did qualify the inclusion of this illustration with a “?”, this cannot justify its exclusion from the protologue, and its existence (as an original element) precludes the designation of a neotype.

description: Gas and dust “protoplanetary disks” that surround young stars are the sites where planets form. It is known that dust particles do not survive temperatures above 1000-2000 K, for which all disks should be cleared of dust close to the central stars. The size of such inner dust holes should be larger for more luminous (hotter) sources, ranging between ~ 0.01 and 20 au in optically-visible young stars. This range is critical for our understanding of planet formation, as it corresponds to the region where most planets’ orbits lie. In turn, those inner disk sizes translate to angular scales of milli-arcsecs even for the closest young stars, for which they can be resolved only from near-infrared interferometry. This poster summarises our work in Marcos-Arenal et al. (2021, A&A 652, A68), where we have inferred inner disk sizes of a sample of young stars based on observations taken with GRAVITY at the ESO/Paranal Interferometer. Our interferometric measurements were complemented with all similar ones from the literature, which were updated by using Gaia EDR3 distances. As a result, we present the most complete “size-luminosity diagram” to date of optically-visible young stars. Although the overall trend relating both parameters is confirmed, there is significant scatter and stars with similar luminosities show widely different inner dust sizes. We have tested the three main hypotheses aiming to account for the observed size-luminosity relation and its scatter: the presence or absence of large amounts of gas close to the central star, alternative disk-to-star accretion mechanisms, and the different dust disk properties as inferred from the spectral energy distributions. None of these scenarios serve as a general explanation, and the origin of the size-luminosity relation and its scatter remains an open question. Future observations avoiding underlying trends with the distance are proposed, which may help to better understand what determines the inner sizes of protoplanetary disks.

description: It was shown earlier that applying a magnetic field during the growth of Sr$_2$IrO$_4$, also known as "field-alteration", induces significant changes to its structural, magnetic, and transport properties. However, the microscopic nature of these changes is enigmatic. In this study, we employed resonant elastic and inelastic x-ray scattering, as well as Raman scattering, to investigate samples from two batches of Sr$_2$IrO$_4$ grown in magnetic fields of different strengths. Our findings reveal that samples grown in a weaker magnetic field have similar magnetic order to non-altered samples, whereas those grown in a stronger field show a different stacking of weak in-plane ferromagnetic moments. Additionally, we observed significant softening and broadening of select Raman-active phonons in the field altered samples, with a stronger effect in the samples grown in the stronger field. We discuss insights that our results provide into the microscopic nature of field-alteration in Sr$_2$IrO$_4$.

description: Multi-object astronomical adaptive-optics (MOAO) is now a mature wide-field observation mode to enlarge the adaptive-optics-corrected field in a few specific locations over tens of arc-minutes. The work-scope provided by open-loop tomography and pupil conjugation is amenable to a spatio-angular Linear-Quadratic Gaussian (SA-LQG) formulation aiming to provide enhanced correction across the field with improved performance over static reconstruction methods and less stringent computational complexity scaling laws. Starting from our previous work [1], we use stochastic time-progression models coupled to approximate sparse measurement operators to outline a suitable SA-LQG formulation capable of delivering near optimal correction. Under the spatio-angular framework the wave-fronts are never explicitly estimated in the volume,providing considerable computational savings on 10m-class telescopes and beyond. We find that for Raven, a 10m-class MOAO system with two science channels, the SA-LQG improves the limiting magnitude by two stellar magnitudes when both Strehl-ratio and Ensquared-energy are used as figures of merit. The sky-coverage is therefore improved by a factor of 5.

description: In this paper a hybridized weak Galerkin (HWG) finite element method for solving the Stokes equations in the primary velocity-pressure formulation is introduced. The WG method uses weak functions and their weak derivatives which are defined as distributions. Weak functions and weak derivatives can be approximated by piecewise polynomials with various degrees. Different combination of polynomial spaces leads to different WG finite element methods, which makes WG methods highly flexible and efficient in practical computation. A Lagrange multiplier is introduced to provide a numerical approximation for certain derivatives of the exact solution. With this new feature, HWG method can be used to deal with jumps of the functions and their flux easily. Optimal order error estimate are established for the corresponding HWG finite element approximations for both {\color{black}primal variables} and the Lagrange multiplier. A Schur complement formulation of the HWG method is derived for implementation purpose. The validity of the theoretical results is demonstrated in numerical tests.

description: The in-plane electrical resistivity, rho, and thermal conductivity, kappa, of the heavy-fermion superconductor CeIrIn5 were measured down to 40mK in magnetic fields up to 11 T applied along the c axis. For all fields above Hc2=4T of filamentary superconductivity, we find that the ratio of heat and charge conductivities in the T to 0 limit obeys the Wiedemann-Franz law, kappa/T=L0/rho, where L0 = 2.45*10^-8 WOhmK^-2 is the Sommerfeld value of the Lorenz number. The temperature-dependent parts of both the electrical and thermal resistivity,w = T/L0 kappa, follow the functional dependence expected for the Fermi liquid theory of metals with rho - rho_0 = AT^2, w - w_0 = BT^2, with rho0 = w0 and B ~ 2A. The coefficient B does not show a significant field dependence even upon approaching Hc2 = 0.4 T of the bulk superconducting state. The weak response to the magnetic field is in stark contrast with the behavior found in the closely related CeCoIn5, in which the field-tuned quantum critical point coincides with Hc2. The value of the electron-electron mass enhancement, as judged by the A and B coefficients, is about one order of magnitude reduced in CeIrIn5 as compared to CeCoIn5 (in spite of the fact that the zero field gamma_0 in CeIrIn5 is twice as large as gamma_0 in CeCoIn5), which suggests that the material is significantly farther away from the magnetic quantum critical point at bulk Hc2 and at all of the studied fields. A suppressed Kadowaki-Woods ratio in CeIrIn5 compared to CeCoIn5 suggests a notably more localized nature of f electrons in the compound.

description: The formation timescale of planetary systems is limited by the lifetime of the protoplanetary disks that surround the stars during their youth. The typical disk lifetime turns out to be smaller than 10 Myr, as inferred from the comparison between the ages of young stellar clusters and their disk frequencies -i.e, the number of stars with disks divided by the total number of members. However, previous disk frequency estimates are based on relatively compact fields of view covering the central 2-3 pc around the clusters’ centers. It is thus unknown if disk frequencies could change when more extended regions are considered, which would have major impact in our view of planet formation and our own planetary system. This poster presents the results of a recent work (Mendigutía et al. 2022, A&A, 664, A66) where we have compared disk frequencies inferred from 2 widely different regions corresponding to 2 pc and 20 pc from the centers of a representative sample of young stellar clusters. Gaia EDR3 parallaxes and proper motions, along with a best suited tool (Clusterix: http://clusterix.cab.inta-csic.es/clusterix/), were used for membership determination. Near-infrared color-color diagrams served to identify disk sources. Our results cover the largest fields ever probed when dealing with disk fractions for all clusters analysed. Although the density of member stars decreases outside the clusters’ centers, the absolute number of members is significantly larger in the peripheries, implying that the complete characterization of young clusters requires to probe wide fields. In turn, our comparative study does not support a previous hypothesis proposing that disk fractions should be significantly larger considering extended regions. On the contrary, disk frequencies inferred from the 2 pc- and 20 pc- regions are typically equal within 10%. A Virtual Observatory-compliant archive (http://svocats.cab.inta-csic.es/diskfrac/) stores the member and disk stars identified in each cluster, along with their membership probabilities, angular distances to the centre, Gaia and near-infrared data. Plots and average results characterizing the whole clusters are also provided, including their Gaia color-magnitude diagrams for the sources with known extinction. The resulting database is a benchmark for future detailed studies of young clusters, whose disk frequencies must be accurately determined by using multi-wavelength analysis potentially combined with data from coming Gaia releases.

description: We investigate the 2D instability recently discussed by Gallet et al. (2010) and Ilin \& Morgulis (2013) which arises when a radial crossflow is imposed on a centrifugally-stable swirling flow. By finding a simpler rectilinear example of the instability - a sheared half plane, the minimal ingredients for the instability are identified and the destabilizing/stabilizing effect of inflow/outflow boundaries clarified. The instability - christened `boundary inflow instability' here - is of critical layer type where this layer is either at the inflow wall and the growth rate is $O(\sqrtη)$ (as found by Ilin \& Morgulis 2013), or in the interior of the flow and the growth rate is $O(η\log 1/η)$ where $η$ measures the (small) inflow-to-tangential-flow ratio. The instability is robust to changes in the rotation profile even to those which are very Rayleigh-stable and the addition of further physics such as viscosity, 3-dimensionality and compressibility but is sensitive to the boundary condition imposed on the tangential velocity field at the inflow boundary. Providing the vorticity is not fixed at the inflow boundary, the instability seems generic and operates by the inflow advecting vorticity present at the boundary across the interior shear. Both the primary bifurcation to 2D states and secondary bifurcations to 3D states are found to be supercritical. Assuming an accretion flow driven by molecular viscosity only so $η=O(Re^{-1})$, the instability is not immediately relevant for accretion disks since the critical threshold is $O(Re^{-2/3})$ and the inflow boundary conditions are more likely to be stress-free than non-slip. However, the analysis presented here does highlight the potential for mass entering a disk to disrupt the orbiting flow if this mass flux possesses vorticity.

description: Magnetar giant flares show oscillatory modulations in the tails of their light curves, which can only be explained via some form of beaming. The fireball model for magnetar bursts has been used successfully to fit the phase-averaged light curves of the tails of giant flares, but so far no attempts have been made to fit the pulsations. We present a relatively simple numerical model to simulate beaming of magnetar flare emission. In our simulations, radiation escapes from the base of a fireball trapped in a dipolar magnetic field, and is scattered through the optically thick magnetosphere of the magnetar until it escapes. Beaming is provided by the presence of a relativistic outflow, as well as by the geometry of the system. We find that a simple picture for the relativistic outflow is enough to create the pulse fraction and sharp peaks observed in pulse profiles of magnetar flares, while without a relativistic outflow the beaming is insufficient to explain giant flare rotational modulations.

description: The contribution of star-forming galaxies to Reionization is still unknown. Using 66 ultraviolet (UV) spectra from the recent Low-Redshift Lyman Continuum Survey (LzLCS) and 23 archival Lyman Continuum (LyC) observations, we form a statistical sample of compact star forming galaxies at z = 0.2 - 0.4 to study the role of the cool Interstellar Medium gas (ISM gas, traced by the UV absorption lines) in the leakage of ionizing radiation (LyC escape fraction, fesc). Strong LyC leakers (high fesc) show weak absorption lines, low UV attenuation, and large Lyman Alpha equivalent widths. The observed non-uniform gas coverage (non-zero residual flux of the UV lines) demonstrates that LyC photons escape through low-column-density channels in a patchy/clumpy ISM. Finally, we show that simultaneous measurement of UV absorption lines and dust attenuation can statistically predict the absolute LyC escape fraction of galaxies, and the method can be applied to study galaxies across a wide redshift range.

description: The linear response of a superfluid, rotating uniformly in a cylindrical container and threaded with a large number of vortex lines, to an impulsive increase in the angular velocity of the container is investigated. At zero temperature and with perfect pinning of vortices to the top and bottom of the container, we demonstrate that the system oscillates persistently with a frequency proportional to the vortex line tension parameter to the quarter power. This low-frequency mode is generated by a secondary flow analogous to classical Ekman pumping that is periodically reversed by the vortex tension in the boundary layers. We compare analytic solutions to the two-fluid equations of Chandler & Baym (1986) with the spin-up experiments of Tsakadze & Tsakadze (1980) in helium II and find the frequency agrees within a factor of four, although the experiment is not perfectly suited to the application of the linear theory. We argue that this oscillatory Ekman pumping mode, and not Tkachenko modes provide a natural explanation for the observed oscillation. In neutron stars, the oscillation period depends on the pinning interaction between neutron vortices and flux tubes in the outer core. Using a simplified pinning model, we demonstrate that strong pinning can accommodate modes with periods of days to years, which are only weakly damped by mutual friction over longer timescales.

 Lectotype (designated here):— SERBIA. Vrška Čuka, s.d., J. Pančić s.n. (BEOU-1861, first specimen from the right), Fig. 7.
 Note:—We located four unmounted specimens on the same sheet in Belgrade (BEOU-1861) that are part of the original material for this taxon. The sheet bears seven separate labels by Pančić and one by Visiani. Four labels by Pančić bear the name “ Dianthus strobifolius ”, a provisional name that Pančić proposed for this species, widely used throughout the correspondence. Two others, including Visiani’s, bear the uncertain determination as Dianthus pinifolius Sm. in Sibthorp & Smith (1809: 284), a closely related species. As it is not possible to link any of the four specimen to the only label bearing a date (1868), but they all were certainly collected before the publication of the protologue, all labels bearing just provisional names, we here select the most complete of the specimens.

description: Fundamental concepts in the quasi-one-dimensional geometry of disordered wires and random waveguides in which ideas of scaling and the transmission matrix were first introduced are reviewed. We discuss the use of the transmission matrix to describe the scaling, fluctuations, delay time, density of states, and control of waves propagating through and within disordered systems. Microwave measurements, random matrix theory calculations, and computer simulations are employed to study the statistics of transmission and focusing in single samples and the scaling of the probability distribution of transmission and transmittance in random ensembles. Finally, we explore the disposition of the energy density of transmission eigenchannels inside random media.

cosmological simulations

description: The Gaia DR2 revealed several substructures in the phase space of the Milky Way's disk, such as the phase spirals in the Z-Vz plane, whose origin is still under study. Further studies have confirmed that the phase spiral can be a consequence of the Sagittarius dwarf galaxy tidal interaction. In our work, we detect phase spirals in the vertical projection Z − Vz of the disc’s stellar particles for the first time in zoom-in cosmological simulations that include hydrodynamics, and star formation and evolution. The detection and characterisation of the phase spirals have been carried out with a Fourier decomposition-based technique. Our algorithm allows us to automatically analyse a large number of snapshots and locations in the simulated galactic disk. Our results indicate that these spiral-like structures in the phase space are present in a wide range of times and locations across the disk and that they become more evident in times close to the satellite pericenters. A novel result of our work is that, as seen in the data, the phase spirals are better observed in the range of younger-intermediate star populations in cosmological simulations. Also, although the satellites of this system are lighter (10⁸ Msun) than the minimum mass estimated to trigger this response (10¹0 Msun), their effect is evident on the kinematics of the stellar disk. We state that other mechanisms might be at play, which appear naturally in our model, such as the physics of gas, the collective effect of multiple perturbers, and a dynamically cold population continuously renovated by the star formation that helps satellites to trigger the observed disk response. We expect that new observations combined with our intensive study of the origin of the phase spirals in fully self-consistent cosmological simulations will provide new insights into the nature/origin of the phase spiral.

description: Here we employ both dynamic and geometric phase control of light to produce radially modulated vector-vortex modes, the natural modes of optical fibers. We then measure these modes using a vector modal decomposition set-up as well as a tomography measurement, the latter providing a degree of the non-separability of the vector states, akin to an entanglement measure for quantum states. We demonstrate the versatility of the approach by creating the natural modes of a step-index fiber, which are known to exhibit strong mode coupling, and measure the modal cross-talk and non-separability decay during propagation. Our approach will be useful in mode division multiplexing schemes for transport of classical and quantum states.

description: Recent large scale surveys of galactic bulge stars allowed to build a detailed map of the bulge kinematics. The bulge exhibits cylindrical rotation consistent with a disky origin which evolved through bar driven secular evolution. However correlations between metallicity and kinematics complicate this picture. In particular a metal-poor component with distinct kinematic signatures has been detected. Its origin, density profile and link with the other Milky Way stellar populations are currently still poorly constrained.
