(1) Causes of seedling mortality in Diplachne fusca were investigated, and the flooding tolerance of seedlings was examined in field and glasshouse experiments in temperate New South Wales, Australia. (2) Seedlings growing under non-flooded conditions in rice crops sown in unflooded soils, were susceptible to water stress, with up to 65% dying. Seedlings emerging in autumn after rain also became water stressed. Those surviving were stunted by cold temperatures or killed by frost or site disturbance. (3) Under controlled flooding conditions, continuous submergence resulted in greater germination than brief irrigations. Delaying permanent flooding gave less germination but fewer deaths after the onset of flooding compared with flooding for the duration of the experiment. Significantly more seedlings established in 4 cm deep permanent floodwater than in 12 cm. (4) In the glasshouse, single-leaved seedlings could establish in 20 cm deep water with no mortality. Submerged seedlings emerged above water level by rapid elongation of the fourth and fifth leaves. (5) A strategy for the control of D. fusca in rice fields is described, using the results of this and previous studies.

description: Private information retrieval scheme for coded data storage is considered in this paper. We focus on the case where the size of each data record is large and hence only the download cost (but not the upload cost for transmitting retrieval queries) is of interest. We prove that the tradeoff between storage cost and retrieval/download cost depends on the number of data records in the system. We also propose a fairly general class of linear storage codes and retrieval schemes and derive conditions under which our retrieval schemes are error-free and private. Tradeoffs between the storage cost and retrieval costs are also obtained. Finally, we consider special cases when the underlying storage code is based on an MDS code. Using our proposed method, we show that a randomly generated retrieval scheme is indeed very likely to be private and error-free.

description: In this paper we study a system of field equations of Penrose-Fife type governing the dynamics of phase transitions with a nonconserved order parameter. In many recent contributions on this subject, the heat flux law has been assumed in the form q = ∇ (1/θ). In contrast to that, here we consider the (more realistic) case of the Fourier law when q is proportional to the negative gradient -∇θ of the (absolute) temperature θ. The assumption of Fourier heat conduction presents particular difficulties in the framework of the Penrose-Fife model, since then the field equation representing the balance of internal energy does not seem to have a maximum principle from which the positivity of θ could be derived. In this connection, we recall that the main difficulty in proving existence for phase-field systems of Penrose-Fife type is the proof of the positivity of θ. It is shown in this paper that in the case without interfacial energy, that is, when the free energy does not contain a quadratic gradient term of the order parameter, there exists a comparatively easy way to conclude the positivity of θ under rather weak and quite natural conditions on the data of the system. Having established this result, the existence of a weak solution is readily obtained using known results on general phase-field systems.

description: The astrophysical origin of the over 90 compact binary mergers discovered by the LIGO and Virgo gravitational wave observatories is an open question. While the unusual mass and spin of some of the discovered objects constrain progenitor scenarios, the observed mergers are consistent with multiple interpretations. A promising approach to solve this question is to consider the observed distributions of binary properties and compare them to expectations from different origin scenarios. Here we describe a new hierarchical population analysis framework to assess the relative contribution of different formation channels simultaneously. For this study we considered binary formation in AGN disks along with phenomenological models, but the same framework can be extended to other models. We find that high-mass and high-mass-ratio binaries appear more likely to have an AGN origin compared to the same origin as lower-mass events. Future observations of high-mass black hole mergers could further disentangle the AGN component from other channels.

description: Der Anstoß, diesen Vortrag zu halten, ist das Lastverteilungsmodell von Karl von Terzaghi, das er 1936 veröffentlicht hat. Es geht von der Fragestellung aus, in welcher Weise eine aufgebrachte Last auf die Komponenten eines porösen Mediums verteilt wird. Dazu sollten wir zunächst klarstellen, was ein poröser Körper ist. Böden, Gesteine, Keramik und faserige Stoffe sind Beispiele für poröse Körper. Diese Stoffe haben alle die Gemeinsamkeit, daß es sich um einen "Feststoff mit Löchern" handelt. Nun würde man einen hohlen Metallzylinder aber kaum als porösen Körper bezeichnen. D.h. man muß die Definition dahingehend erweitern, daß es sich um einen Körper mit mindestens einer festen Phase handelt, der zufällig verteilte Hohlräume aufweist, die miteinander verbunden sind und von denen wenigstens einige von der einen Seite des Mediums bis zur anderen verlaufen. Wir wollen hier einen zweikomponentigen porösen Körper betrachten, einen Körper bestehend aus einer festen Phase (Skelett) und einer flüssigen Phase (Fluid). Durch die zweite Phase wird neben der Porosität eine zweite Eigenschaft des porösen Körpers erfaßt, die wichtige physikalische Beiträge leistet, nämlich die Diffusion.

description: Widefield quantum microscopy based on nitrogen-vacancy (NV) centres in diamond has emerged as a powerful technique for quantitative mapping of magnetic fields with a sub-micron resolution. However, the accuracy of the technique has not been characterised in detail so far. Here we show that optical aberrations in the imaging system may cause large systematic errors in the measured quantity beyond trivial blurring. We introduce a simple theoretical framework to model these effects, which extends the concept of a point spread function to the domain of spectral imaging. Using this model, the magnetic field imaging of test magnetic samples is simulated under various scenarios, and the resulting errors quantified. We then apply the model to previously published data, show that apparent magnetic anomalies can be explained by the presence of optical aberrations, and demonstrate a post-processing technique to retrieve the source quantity with improved accuracy. This work presents a guide to predict and mitigate aberration induced artefacts in quantitative NV-based widefield imaging and in spectral imaging more generally.

description: The orientation between a star's spin axis and a planet's orbital plane provides valuable information about the system's formation and dynamical history. For non-transiting planets at wide separations, true stellar obliquities are challenging to measure, but lower limits on spin-orbit orientations can be determined from the difference between the inclination of the star's rotational axis and the companion's orbital plane ($Δi$). We present results of a uniform analysis of rotation periods, stellar inclinations, and obliquities of cool stars (SpT $\gtrsim$ F5) hosting directly imaged planets and brown dwarf companions. As part of this effort, we have acquired new $v \sin i_*$ values for 22 host stars with the high-resolution Tull spectrograph at the Harlan J. Smith telescope. Altogether our sample contains 62 host stars with rotation periods, most of which are newly measured using light curves from the Transiting Exoplanet Survey Satellite. Among these, 53 stars have inclinations determined from projected rotational and equatorial velocities, and 21 stars predominantly hosting brown dwarfs have constraints on $Δi$. Eleven of these (52$^{+10}_{-11}$% of the sample) are likely misaligned, while the remaining ten host stars are consistent with spin-orbit alignment. As an ensemble, the minimum obliquity distribution between 10-250 AU is more consistent with a mixture of isotropic and aligned systems than either extreme scenario alone--pointing to direct cloud collapse, formation within disks bearing primordial alignments and misalignments, or architectures processed by dynamical evolution. This contrasts with stars hosting directly imaged planets, which show a preference for low obliquities. These results reinforce an emerging distinction between the orbits of long-period brown dwarfs and giant planets in terms of their stellar obliquities and orbital eccentricities.

We prove that H generates a C0-group of bounded operators in a suitable Hilbert space 풰, that all but finitely many eigenvalues of H are simple and have negative real parts and that there exists a basis in 풰 consisting of root functions of H, where all but finitely many of these root functions are eigenfunctions.

description: Stellar rotation is of key importance for the formation process, evolution, and final fate of massive stars. In this paper we review results from the study of the spin rate properties of a sample of more than 400 Galactic O-type stars surveyed by the IACOB and OWN projects. By combining vsini, Teff, and logg estimates (resulting from a detailed quantitative spectroscopic analysis) with information about the spectroscopic binarity status for an important fraction of the stars in the sample, we provide a renewed overview about how the empirical distribution of projected rotational velocities in the O-star domain depends on mass, evolutionary and binary status. The obtained distributions are then compared with predictions of several state-of-the-art evolutionary models for single stars, as well as from population synthesis simulations including binary interaction, and used to provide hints about the initial velocity distribution of stars with masses in the range ~15-80 Msol.

Expediting Feller process with stochastic resetting

Publisher: name: arXiv
Year: 2022
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We explore the effect of stochastic resetting on the first-passage properties of Feller process. The Feller process can be envisioned as space-dependent diffusion, with diffusion coefficient $D(x)=x$, in a potential $U(x)=x\left(\frac{x}{2}-θ\right)$ that owns a minimum at $θ$. This restricts the process to the positive side of the origin and therefore, Feller diffusion can successfully model a vast array of phenomena in biological and social sciences, where realization of negative values is forbidden. In our analytically tractable model system, a particle that undergoes Feller diffusion is subject to Poissonian resetting, i.e., taken back to its initial position at a constant rate $r$, after random time epochs. We addressed the two distinct cases that arise when the relative position of the absorbing boundary ($x_a$) with respect to the initial position of the particle ($x_0$) differ, i.e., for (a) $x_0θ_c$, where $θ_c$ is a critical value of $θ$ that increases when $x_0$ is moved away from the origin. Our study opens up the possibility of a series of subsequent works with more case-specific models of Feller diffusion with resetting.

description: Phase-field systems as mathematical models to forecast the evolution of processes involving phase transitions have drawn a considerable interest in recent years. However, while they are capable of capturing many of the experimentally observed phenomena, they are only of restricted value in modelling hysteresis effects occuring during phase transition processes. To overcome this shortcoming, a new approach to phase-field models is proposed in this paper which is based on the mathematical theory of hysteresis operators developed in the past fifteen years. The approach taken here leads to highly nonlinearly coupled systems of differential equations containing hysteretic nonlinearities at different places. For such a system, well-posedness and thermodynamic consistency are proved. Due to the lack of smoothness (hysteresis operators are, as a rule, non-differentiable) in the system, the method of proof has to be different from those usually employed for classical phase-field systems.

We first review, in a systematic way, news from heterogeneous social media sources; we discuss the fragility of the Terra project and its vicious dependence on the Anchor protocol. We hence identify the crash's trigger events, analysing hourly and transaction data for Bitcoin, Luna, and TerraUSD. Finally, using state-of-the-art techniques from network science, we study the evolution of dependency structures for 61 highly capitalised cryptocurrencies during the down-market and we also highlight the absence of herding behaviour analysing cross-sectional absolute deviation of returns.

description: Road sign recognition is one of the core technologies in Intelligent Transport Systems. In the current study, a robust and real-time method is presented to identify and detect the roads speed signs in road image in different situations. In our proposed method, first, the connected components are created in the main image using the edge detection and mathematical morphology and the location of the road signs extracted by the geometric and color data; then the letters are segmented and recognized by Multiclass Support Vector Machine (SVMs) classifiers. Regarding that the geometric and color features ate properly used in detection the location of the road signs, so it is not sensitive to the distance and noise and has higher speed and efficiency. In the result part, the proposed approach is applied on Iranian road speed sign database and the detection and recognition accuracy rate achieved 98.66% and 100% respectively.
The Path from the Chinese and Japanese Observations of Supernova 1181 AD, to a Type Iax Supernova, to the Merger of CO and ONe White Dwarfs

description: In 1181 AD, Chinese and Japanese observers reported an unmoving bright `Guest Star' in the constellation Chuanshe, visible for 185 days. In 2013, D. Patchick discovered what turned out to be a unique nebula surrounding a unique star, with the structure named `Pa 30', while subsequent workers made connections to mergers of white dwarfs, to the supernova subclass of low-luminosity Type Iax, and to the 1181 transient. Here, I provide a wide range of new observational evidence: First, detailed analysis of the original Chinese and Japanese reports places the `Guest Star' of 1181 into a small region with the only interesting source being Pa 30. Second, the ancient records confidently place the peak magnitude as 0.0$>$$V_{\rm peak}$$>$$-$1.4, and hence peak absolute magnitude $-$14.5$>$$M_{\rm V,peak}$$>$$-$16.0 mag. Third, the Pa 30 central star is fading from $B$=14.9 in 1889, to $B$=16.20 in 1950, to $B$=16.58 in 2022. Fourth, recent light curves show typical variability with full-amplitude of 0.24 mag on time-scales of one day and longer, critically with no coherent modulations for periods from 0.00046--10 days to strict limits. Fifth, the spectral energy distribution from the far-infrared to the ultraviolet is a nearly-perfect power-law with $F_ν\proptoν^{0.99\pm0.07}$, observed luminosity 128$\pm$24 L$_{\odot}$, and absolute magnitude $M_{\rm V}$=$+$1.07. I collect my new evidences with literature results to make a confident case to connect the East-Asian observations to a supernova, then to Pa 30, then to a low-luminosity Type Iax SN, then to the only possible explosion mechanism as a merger between CO and ONe white dwarfs.

description: We investigate the solar phenomena associated with the origin of the solar energetic particle (SEP) event observed on 2013 April 11 by a number of spacecraft distributed in the inner heliosphere over a broad range of heliolongitudes. We use Extreme UltraViolet (EUV) and white-light coronagraph observations from the Solar Dynamics Observatory (SDO), the SOlar and Heliospheric Observatory (SOHO) and the twin Solar TErrestrial RElations Observatory spacecraft (STEREO-A and STEREO-B) to determine the angular extent of the EUV wave and coronal mass ejection (CME) associated with the origin of the SEP event. We compare the estimated release time of SEPs observed at each spacecraft with the arrival time of the structures associated with the CME at the footpoints of the field lines connecting each spacecraft with the Sun. Whereas the arrival of the EUV wave and CME-driven shock at the footpoint of STEREO-B is consistent, within uncertainties, with the release time of the particles observed by this spacecraft, the EUV wave never reached the footpoint of the field lines connecting near-Earth observers with the Sun, even though an intense SEP event was observed there. We show that the west flank of the CME-driven shock propagating at high altitudes above the solar surface was most likely the source of the particles observed near Earth, but it did not leave any EUV trace on the solar disk. We conclude that the angular extent of the EUV wave on the solar surface did not agree with the longitudinal extent of the SEP event in the heliosphere. Hence EUV waves cannot be used reliably as a proxy for the solar phenomena that accelerates and injects energetic particles over broad ranges of longitudes.

The results of four field surveys for Rotifera in Tasmania are summarized. Most new species and records in a 1987 survey were from acid waters (pH < 4.0) of dune lakes on the west coast (42° S). Marked intra- and interhabitat differences in rotifer communities of lakes and ponds were demonstrated by cluster analysis and related to habitat heterogeneity.
Charge and spin polarized currents in mesoscopic rings with Rashba spin-orbit interactions coupled to an electron reservoir

description: The electronic states of a mesoscopic ring are assessed in the presence of Rashba Spin Orbit coupling and a $U(1)$ gauge field. Spin symmetric coupling to an ideal lead is implemented following Büttiker's voltage probe. The exact density of states is derived using the reservoir uncoupled eigenstates as basis functions mixed by the reservoir coupling. The decay time of uncoupled electron eigenstates is derived by fitting the broadening profiles. The spin and charge persistent currents are computed in the presence of the SO interaction and the reservoir coupling for two distinct scenarios of the electron filling fraction. The degradation of the persistent currents depends uniformly on the reservoir coupling but nonuniformly in temperature, the latter due to the fact that currents emerge from different depths of the Fermi sea, and thus for some regimes of flux, they are provided with a protective gap. Such flux regimes can be tailored by the SO coupling for both charge and spin currents.

description: In this work, we analyze a sample of $\sim$4000 massive ($M_*\geq 10^{11} M_\odot$ at $z=0$) galaxies in TNG300, the $(300 \mathrm{Mpc})^3$ box of the IllustrisTNG simulation suite. We characterize the shape and kinematics of these galaxies with a focus on the kinematic misalignment ($Ψ_\mathrm{int}$) between the angular momentum (AM) and morphological major axis. We find that the traditional purely shape- or kinematics-based classifications are insufficient to characterize the diversity of our sample and define a new set of classes based on the rates of change of the galaxies' morphological and kinematic axes. We show that these classes are mostly stable over time and correspond to six distinct populations of galaxies: the rapid AM reorienters (58% of our sample), unsettled galaxies (10%), spinning disks (10%), twirling cigars (16%), misaligned slow reorienters (3%), and regular prolate rotators (galaxies that display major axis rotation; 2%). We demonstrate that the most-recent significant (mass-ratio $μ>1/10$) mergers of these galaxies are the primary cause for their present-day properties and find that these mergers are best characterized at the point of the satellite's final infall -- that is, much closer to the final coalescence than has been previously thought. We show that regular prolate rotators evolve from spinning disk progenitors that experience a radial merger along their internal AM direction. Finally, we argue that these regular prolate rotators are distinct from the similarly-sized population of rapid AM reorienters with large $Ψ_\mathrm{int}$, implying that a large $Ψ_\mathrm{int}$ is not a sufficient condition for major axis rotation.

description: Signed Particle Monte Carlo (SPMC) approach has been used in the past to model steady-state and transient dynamics of the Wigner quasi-distribution for electrons in low dimensional semiconductors. Here we make a step towards high-dimensional quantum phase-space simulation in chemically relevant scenarios by improving the stability and memory demands of SPMC in 2D. We do so by using an unbiased propagator for SPMC to improve trajectory stability and by applying machine learning to reduce memory demands for storage and manipulation of the Wigner potential. We perform computational experiments on a 2D double-well toymodel of proton transfer and demonstrate stable pico-second-long trajectories that require only a modest computational effort.

description: We present a practical design and implementation of a broadband sample holder suitable for microwave experiments with superconducting integrated circuits at millikelvin temperatures. Proposed design can be easily integrated in standard dilution cryostats, has flat pass band response in a frequency range from 0 to 32 GHz, allowing the RF testing of the samples with substrate size up to 4x4 mm. The parasitic higher modes interference in the holder structure is analyzed and prevented via design considerations. The developed setup can be used for characterization of superconducting parametric amplifiers, bolometers and qubits. We tested the designed sample holder by characterizing of a superconducting flux qubit at 20 mK temperature.

On the time of existence of weak discontinuity waves in poroelastic materials
Creators: name: Wilmański, Krzysztof
Publisher: name: Weierstrass Institute
Year: 1997

description: In the paper, we consider the possibility of the growth of strong discontinuity waves in the two-component poroelastic materials. We use the model with the hyperbolic set of field equations described in the paper K. Wilmanski [19961]. It is shown that indeed the critical time (i.e. the maximum time of existence of classical solutions) is finite and it assumes realistic values for real physical systems, such as biological tissues.

description: Building machine translation (MT) test sets is a relatively expensive task. As MT becomes increasingly desired for more and more language pairs and more and more domains, it becomes necessary to build test sets for each case. In this paper, we investigate using Amazon's Mechanical Turk (MTurk) to make MT test sets cheaply. We find that MTurk can be used to make test sets much cheaper than professionally-produced test sets. More importantly, in experiments with multiple MT systems, we find that the MTurk-produced test sets yield essentially the same conclusions regarding system performance as the professionally-produced test sets yield.

description: Les symptômes négatifs, qui font référence à une réduction du fonctionnement normal, ne réagissent généralement pas ou peu aux traitements pharmacologiques et psychothérapeutiques et représentent donc un grand défi dans la prise en soins des personnes souffrant de schizophrénie. L'émergence de nouvelles interventions issues de la psychologie positive pourraient potentiellement aider une personne à gérer les symptômes et les déficits associés à la schizophrénie. Le module PEPS (Programme Emotions Positives pour la Schizophrénie) est une de ces interventions, et a pour but la réduction de l’anhédonie et de l’apathie. Une première étude pilote a été réalisée. Les résultats montrent une amélioration de l’anhédonie, de l’apathie et de la dépression chez les participants.

An investigation of the flow structure beneath solitary waves with constant vorticity on a conducting fluid under normal electric fields

description: The motion of an interface separating two fluids under the effect of electric fields is a subject that has picked the attention of researchers from different areas. While there is an abundance of studies investigating the free surface wave properties, very few works have examined the associated velocity field within the bulk of the fluid. Therefore, in this paper, we investigate numerically the flow structure beneath solitary waves with constant vorticity on an inviscid conducting fluid bounded above by a dielectric gas under normal electric fields in the framework of a weakly nonlinear theory. Elevation and depression solitary waves with constant vorticity are computed by a pseudo-spectral method and a parameter sweep on the intensity of the electric field is carried out in order to study its role in the appearance of stagnation points. We find that for elevation solitary waves the location of stagnation points does not change significantly with variations of the electric field. For depression solitary waves, on the other hand, the electric field acts as a catalyser that makes possible the appearance of stagnation points - in the sense that in its absence there is no stagnation point.
Quelles pratiques intégratives sont privilégiées par des enseignants secondaires lorsqu’ils accueillent en stage un élève de classe D ?

description: Ce Mémoire professionnel propose d’analyser certaines pratiques intégratives favorisées par des enseignants secondaires, lorsqu’ils accueillent dans leur classe respective un élève provenant d’une classe de développement du canton de Vaud. Le contexte de cette recherche est celui d’un établissement secondaire ordinaire. Plus précisément, l’objectif de cet écrit est de mieux appréhender l’encadrement des stages d’intégration de trois semaines organisés dans cette école. Ces expériences sont généralement proposées aux élèves qui ont le projet de rejoindre le système d’enseignement régulier. En effet, lorsque les lacunes scolaires ont pu être suffisamment comblées, l’intention première reste l’obtention du certificat de voie générale. Ce choix paraît d’autant plus judicieux qu’il facilite l’entrée dans le monde de la formation professionnelle. En s’intéressant plus particulièrement à une phase de transition spécifique, cette recherche a pour ambition de questionner les pratiques recueillies auprès de six enseignants, en les confrontant aux apports théoriques rassemblés sur la notion d’intégration scolaire. Ainsi, le cadre méthodologique de ce travail ne vise pas une généralisation des données, mais une meilleure compréhension des actions privilégiées dans un contexte précis. Alors que les recommandations politiques actuelles tendent à promouvoir la prise en charge intégrative des élèves en difficultés scolaires ou en situation de handicap, mieux comprendre cette phase d’évaluation paraît essentiel pour envisager une évolution progressive des démarches actuellement privilégiées. A ce sujet, la partie conclusive propose de pointer d’autres pistes d’intervention qui paraissent envisageables dans une école ordinaire. Les gestes professionnels analysés dans ce mémoire se centrent sur les thématiques suivantes : l’intégration sociale de l’élève placé en stage, la collaboration développée durant ces expériences intégratives, la différenciation mise en place par les professionnels dans les classes d’accueil, l’évaluation de la progression du stagiaire ainsi que, pour conclure, les régulations privilégiées pour soutenir au mieux sa progression dans cette phase de transition.

description: A strong superconducting diode effect (SDE) is revealed in a thin superconducting film periodically nanostructured with magnetic dots. The SDE is caused by the current-activated dissipation mitigated by vortex-antivortex pairs (VAPs), which periodically nucleate under the dots, move and annihilate in the superconductor - eventually driving the system to the high-resistive state. Inversing the polarity of the applied current destimulates the nucleation of VAPs, the system remains superconducting up to far larger currents, leading to the pronounced diodic response. Our dissipative Ginzburg-Landau simulations detail the involved processes, and provide reliable geometric and parametric ranges for the experimental realization of such a non-volatile superconducting diode, which operates in absence of any applied magnetic field while being fluxonic by design.

description: AbstractEarly Mediaeval Archaeology was long influenced by traditional narratives related to so-called Völkerwanderungen. Based on the interpretation of ancient written sources, the “Migration Period” was traditionally perceived as a time of catastrophic changes triggered by the collapse of the Western Roman Empire and massive migration waves of “barbarian” groups across Europe. In the last decades, isotope analyses have been increasingly used to test these traditional narratives by exploring past mobility patterns, shifts in dietary habits, and changes in subsistence strategies or in socio-economic structures among early medieval societies. To evaluate the achievements of isotope studies in understanding the complexity of the so-called Migration Period, this paper presents a review of 50 recent publications. Instead of re-analysing the data per se, this review first explores the potentials and limitations of the various approaches introduced in the last decades. In a second step, an analysis of the interpretations presented in the reviewed studies questions to what extend traditional expectations are supported by isotope data from the Migration Period. Beside revising the concept of massive migrations, isotope data reveal so-far underestimated mobility patterns and open new perspectives in the investigation of early medieval world.
