description: No abstracts are to be cited without prior reference to the author.We examined growth of the Arctic bivalve Clinocardium ciliatum from 1977-2006 in the Barents Sea to evaluate the effect of different water masses on growth and to assess the influence of climatic forcing on ecological processes over decadal scales. Analysis of annually-deposited growth lines in shells of 22 individuals from 3 stations allowed us to assess growth conditions for up to 30 years, thus encompassing both warmer and colder climatic phases of the last century. Growth rates of specimens at younger ages (6-13 years) were highest in Atlantic water, resulting in an average size 20% greater compared to similarly aged individuals from Arctic water or at the Polar Front, reflecting warmer sea temperatures and/or presumably greater food supplies in the Atlantic-dominated regions of the Barents Sea. Despite different absolute growth rates, temporal patterns of ontogenetically-adjusted growth (i.e. Standard Growth Index = SGI) had similar features, with below-average but increasing SGI throughout the 1980s and culminating in 1994 or 1995 with the highest SGI. An abrupt decline starting in 1996 led to below-average growth rates for most of the years from the turn of the century to the end of the record in 2006. The decline in growth coincides with abrupt phase shifts in two hemispheric oscillatory indices: the North Atlantic Oscillation (NAO) and the Arctic Climate Regime Index (ACRI). The strongest statistical relationships were found between growth and the ACRI, and its local manifestations through precipitation

description: In recent years numerous advanced malware, aka advanced persistent threats (APT) are allegedly developed by nation-states. The task of attributing an APT to a specific nation-state is extremely challenging for several reasons. Each nation-state has usually more than a single cyber unit that develops such advanced malware, rendering traditional authorship attribution algorithms useless. Furthermore, those APTs use state-of-the-art evasion techniques, making feature extraction challenging. Finally, the dataset of such available APTs is extremely small. In this paper we describe how deep neural networks (DNN) could be successfully employed for nation-state APT attribution. We use sandbox reports (recording the behavior of the APT when run dynamically) as raw input for the neural network, allowing the DNN to learn high level feature abstractions of the APTs itself. Using a test set of 1,000 Chinese and Russian developed APTs, we achieved an accuracy rate of 94.6%.

description: No abstracts are to be cited without prior reference to the author.This study explores the various relationships between distance from the sea ice edge and minke whale density distribution by means of a circumpolar spatial analysis. For almost 30 years, the International Whaling Commission (IWC) has conducted whale surveys in the Southern Ocean during austral summer months under the IWC/IDCR-SOWER programme. This has resulted in three circumpolar sets of surveys, with over 21,000 minke whale sightings. We used these sightings in spatial models of line transect data based on generalised additive models (GAMs). The GAMs assumed an overdispersed Poisson error structure and log-link. Model selection was based on maximisation of explained deviance and minimising the Generalised Cross Validation (GCV) score, while excluding GAMs that generated extreme and unlikely minke whale densities. The GAMs were fitted independently by survey area and year. Selected GAMs included combinations of the following covariates: closest distance of sighting to sea ice edge, closest distance of sighting to either the Southern Antarctic Circumpolar Current Front (SACCF) or the Southern Boundary of the Antarctic Circumpolar Current (SBACC), bathymetric depth and distance from the shelf edge, Optimally Interpolated Sea Surface Temperature (OISST) and latitude. Minke whale densities did not show a consistent relationship with distance from the sea ice edge over the years, suggesting variability in minke whale distribution between years. For most of the regions within the Southern Ocean, mean predicted Antarctic minke whale densities were lowest for the most recent surveys. We plan to investigate if the declining trend in Antarctic minke whale density was accompanied by changes in the sea ice environment, such as changes in total sea ice extent, melt area or quality

description: In this paper we find an explicit formula for the most general vector evolution of curves on $RP^{n-1}$ invariant under the projective action of $SL(n,R)$. When this formula is applied to the projectivization of solution curves of scalar Lax operators with periodic coefficients, one obtains a corresponding evolution in the space of such operators. We conjecture that this evolution is identical to the second KdV Hamiltonian evolution under appropriate conditions. These conditions give a Hamiltonian interpretation of general vector differential invariants for the projective action of $SL(n,R)$, namely, the $SL(n,R)$ invariant evolution can be written so that a general vector differential invariant corresponds to the Hamiltonian pseudo-differential operator. We find common coordinates and simplify both evolutions so that one can attempt to prove the equivalence for arbitrary $n$.

description: We present Giant Metrewave Radio Telescope HI 21cm absorption observations, of candidate and confirmed damped Lyman-$α$ systems (DLAS). The derived spin temperatures (T_s) are in all cases $\sim 1000$ K or higher. We have also collated from the literature a list of DLAS for which 21cm observations exist, and discuss their implications for the nature of the absorbers. A cross-comparison of the 21cm profiles with low ionization metal profiles shows that the 21cm absorption coincides in velocity with the deepest metal line feature. This is consistent with models in which the deep metal line features arise from discrete clouds but not with models where the deepest features are the result of velocity crowding. We also find that the typical derived spin temperatures of DLAS are considerably higher than those in the Galaxy or nearby spirals. The only exceptions are DLAS which are known to be associated with the disks of spirals; these do, in fact, show low spin temperatures. In a multi-phase medium,the derived T_s is a weighted average of the temperatures of the individual phases. High derived T_s values are hence to be expected from small, low metallicity objects, since these objects should have a lower fraction of the cold phase in their ISM as compared to large galaxies. The high T_s in DLAS is hence consistent with their observed low metallicities as well as with recent observations that DLAS are also associated with dwarf/LSB galaxies. Finally, we suggest that the following trend may be identified: at low redshift, damped absorption arises from a range of systems, including spiral galaxy disks, while, at high redshift, absorption occurs predominantly in smaller systems.

description: An analysis of 2,765 articles published in four math journals from 1997 to 2005 indicate that articles deposited in the arXiv received 35% more citations on average than non-deposited articles (an advantage of about 1.1 citations per article), and that this difference was most pronounced for highly-cited articles. Open Access, Early View, and Quality Differential were examined as three non-exclusive postulates for explaining the citation advantage. There was little support for a universal Open Access explanation, and no empirical support for Early View. There was some inferential support for a Quality Differential brought about by more highly-citable articles being deposited in the arXiv. In spite of their citation advantage, arXiv-deposited articles received 23% fewer downloads from the publisher's website (about 10 fewer downloads per article) in all but the most recent two years after publication. The data suggest that arXiv and the publisher's website may be fulfilling distinct functional needs of the reader.

description: The theory of magnetohydrodynamics is extended to the cases of a plasma of separate magnetic and electric charges, as well as to a plasma of dyons respectively. In both these cases the system possesses electric-magnetic duality symmetry. In the former case we find that because of the existence of two independent generalized Ohm's law equations, the limit of infinite electric and magnetic conductivity results in the vanishing of both electric and magnetic fields, as well as the corresponding currents. In the dyonic case, we find that the resulting duality-invariant system of equations are equivalent to those of ordinary MHD, after suitable field redefinitions.

description: No abstracts are to be cited without prior reference to the author.Relatively little is known about the adaptive capacity of ringed seals (Phoca hispida) to climate change in many parts of their range. However, because the species requires certain sea ice and snow conditions to successfully overwinter and rear a pup, ringed seals are thought to be sensitive to climatic variability that alters these required habitat characteristics. The pups are born in a protective snow cave (lair) constructed by the female near a well-drifted pressure ridge or ice hummock on landfast ice or relatively stable pack-ice. Adequate snow cover and/or appropriate ice roughness have been correlated with increased survival of ringed seal pups in the High Arctic and in Hudson Bay. The objective of this study was to map and quantify the available habitat for breeding ringed seals using RADARSAT imagery of ice conditions during February and March and data collected by on-ice teams of hunters from the communities of Nain, Hopedale and Rigolet, Labrador. Ice and snow condition data from 2001-2006 at the Nain study area illustrated how expansive intrusions of highly deformed rough ice (2004), extensive sheets of smooth ice (2006), inadequate snow cover (2001 and 2002), an abrupt and early spring melt (2003), and spring storm events (2005, 2006) impacted the availability of suitable pupping habitat. Although, the occurrence and degree of ice deformation was the key determinant of quality habitat, persistent snow accumulation on the ice and the maintenance of a stable ice platform despite severe, unseasonable spring storms (i.e. high seas and rain) appeared to be critical.
Constraints on Macroscopic Realism Without Assuming Non-Invasive Measurability

description: Macroscopic realism is the thesis that macroscopically observable properties must always have definite values. The idea was introduced by Leggett and Garg (1985), who wished to show a conflict with the predictions of quantum theory. However, their analysis required not just the assumption of macroscopic realism per se, but also that the observable properties could be measured non-invasively. In recent years there has been increasing interest in experimental tests of the violation of the Leggett-Garg inequality, but it has remained a matter of controversy whether this second assumption is a reasonable requirement for a macroscopic realist view of quantum theory. In a recent critical assessment Maroney and Timpson (2017) identified three different categories of macroscopic realism, and argued that only the simplest category could be ruled out by Leggett-Garg inequality violations. Allen, Maroney, and Gogioso (2016) then showed that the second of these approaches was also incompatible with quantum theory in Hilbert spaces of dimension 4 or higher. However, we show that the distinction introduced by Maroney and Timpson between the second and third approaches is not noise tolerant, so unfortunately Allen's result, as given, is not directly empirically testable. In this paper we replace Maroney and Timpson's three categories with a parameterization of macroscopic realist models, which can be related to experimental observations in a noise tolerant way, and recover the original definitions in the noise-free limit. We show how this parameterization can be used to experimentally rule out classes of macroscopic realism in Hilbert spaces of dimension 3 or higher, including the category tested by the Leggett-Garg inequality, without any use of the non-invasive measurability assumption.

Magnetocentrifugal acceleration of plasma in a nonaxisymmetric magnetosphere

Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Violation of the axial synnetry of a magnetic field essentially modifies the physics of the plasma outflow in the magnetosphere of rotating objects. In comparison to the axisymmetric outflow, two new affects appear: more efficient magnetocentrifugal acceleration of the plasma along particular field lines and generation of MHD waves. Here, we use an ideal MHD approximation to study the dynamics of a cold wind in the nonaxisymmetric magnetosphere. We obtain a self-consistent analytical solution of the problem of cold plasma outflow from a slowly rotating star with a slightly nonaxisymmetric magnetic field using perturbation theory. In the axisymmetric (monopole-like) magnetic field, the first term in the expansion of the terminating energy of the plasama in powers of $Ω$ is proportional to $Ω^4$, where $Ω$ is the angular velocity of the central source. Violation of the axial symmetry of the magnetic field crucially changes this dependence. The first correction to the energy of the plasma becomes proportional to $Ω$. Efficient magnetocentrifugal acceleration occurs along the field lines curved initially in the direction of the rotation. I argue that all necessary conditions for the efficient magnetocentrifugal acceleration of the plasma exist in the radio pulsar megnetosphere. We calculated the first correction of the rotational losses due to the generation of the MHD waves and analysed the plasma acceleration by these waves.

description: In the case of a metastable electroweak vacuum the quantum corrected effective potential plays a crucial role in the potential instability of the Standard Model. In the Early Universe, in particular during inflation and reheating, this instability can be triggered leading to catastrophic vacuum decay. We discuss how the large spacetime curvature of the Early Universe can be incorporated in the calculation and in many cases significantly modify the flat space prediction. The two key new elements are the unavoidable generation of the non-minimal coupling between the Higgs field and the scalar curvature of gravity and a curvature induced contribution to the running of the constants. For the minimal set up of the Standard Model and a decoupled inflation sector we show how a metastable vacuum can lead to very tight bounds for the non-minimal coupling. We also discuss a novel and very much related dark matter generation mechanism.

description: No abstracts are to be cited without prior reference to the author.The harp seal is a medium sized highly migratory phocid distributed over continental shelf regions of the north Atlantic. The Northwest Atlantic population currently numbers around 5.5 million animals and is harvested commercially and for subsistence purposes. Harp seals use pack ice to haul out on, to give birth and nurse their young. After weaning the young of the year (YOY) remain with the ice, which they use as a resting platform. The harp seal population is assessed approximately every 4 years using a population model that relies upon independent estimates of pup production obtained from aerial surveys. Since the current harvest is focused on YOY animals, the impact of any unusual mortality will not be reflected in the assessment for at least two decades later. In the Gulf of St. Lawrence, poor ice conditions, which are thought to lead to increased mortality among young animals, have been observed in 6 of the last 10 years. A factor to account for increased mortality during poor ice years has been incorporated into the assessment model since 2004, but the impacts of this factor on model predictions has not been evaluated. Under scenarios of a constant harvest, an annual mortality of 30% or higher, due to ice, in a single year would result in significant changes in the population trajectory within a decade, but these changes would not be noticed as detectable changes in pup production for at least 20 years. Repeated ice-related mortality of 10% had limited impact unless it occurred in 6 or more winters within a decade. Changes in the population and pup production due to increased YOY mortality could not be detected until 15 or more years had passed even under high levels of mortality or variability among years, by which time significant changes in the population can occur. For management considerations, taking into account possible changes in natural mortality due to ice would not appear to be important in the short-term, but will have more important longer term implications.

description: We investigate the contribution of outer HI disks to the observable population of merging black hole binaries. Like dwarf galaxies, the outer HI disks of spirals have low star formation rates and lower metallicities than the inner disks of spirals. Since low-metallicity star formation can produce more detectable compact binaries than typical star formation, the environments in the outskirts of spiral galaxies may be conducive to producing a rich population of massive binary black holes. We consider here both detailed controlled simulations of spirals and cosmological simulations, as well as the current range of observed values for metallicity and star formation in outer disks. We find that outer HI disks contribute at least as much as dwarf galaxies do to the observed LIGO/Virgo detection rates. Identifying the host galaxies of merging massive black holes should provide constraints on cosmological parameters and insights into the formation channels of binary mergers.

description: It is shown that the series derived by Mizrahi, giving the Husimi transform (or covariant symbol) of an operator product, is absolutely convergent for a large class of operators. In particular, the generalized Liouville equation, describing the time evolution of the Husimi function, is absolutely convergent for a large class of Hamiltonians. By contrast, the series derived by Groenewold, giving the Weyl transform of an operator product, is often only asymptotic, or even undefined. The result is used to derive an alternative way of expressing expectation values in terms of the Husimi function. The advantage of this formula is that it applies in many of the cases where the anti-Husimi transform (or contravariant symbol) is so highly singular that it fails to exist as a tempered distribution.

description: We present RXTE monitoring observations of the Seyfert 2 galaxy Mrk 348 spanning a 6 month period. The time-averaged spectrum in the 3-20 keV band shows many features characteristic of a Compton-thin Seyfert 2 galaxy, namely a hard underlying power-law continuum (photon index = 1.8) with heavy soft X-ray absorption (N_h ~ 10^23 cm^-2) plus measureable iron line emission (equivalent width ~ 100 eV) and, at high energy, evidence for a reflection component (R < 1). During the first half of the monitoring period the X-ray continuum flux from Mrk 348 remained relatively steady. However this was followed by a significant brightening of the source (by roughly a factor of 4) with the fastest change corresponding to a doubling of its X-ray flux on a timescale of about 20 days. The flux increase was accompanied by a marked softening of X-ray spectrum most likely attributable to a factor 3 decline in the intrinsic line-of-sight column density. In contrast the iron line and the reflection components showed no evidence of variability. These observations suggest a scenario in which the central X-ray source is surrounded by a patchy distribution of absorbing material located within about a light-week of the nucleus of Mrk 348. The random movement of individual clouds within the absorbing screen, across our line of sight, produces substantial temporal variations in the measured column density on timescales of weeks to months and gives rise to the observed X-ray spectral variability. However, as viewed from the nucleus the global coverage and typical thickness of the cloud layer remains relatively constant.

description: We present an end-to-end learning method for chess, relying on deep neural networks. Without any a priori knowledge, in particular without any knowledge regarding the rules of chess, a deep neural network is trained using a combination of unsupervised pretraining and supervised training. The unsupervised training extracts high level features from a given position, and the supervised training learns to compare two chess positions and select the more favorable one. The training relies entirely on datasets of several million chess games, and no further domain specific knowledge is incorporated. The experiments show that the resulting neural network (referred to as DeepChess) is on a par with state-of-the-art chess playing programs, which have been developed through many years of manual feature selection and tuning. DeepChess is the first end-to-end machine learning-based method that results in a grandmaster-level chess playing performance.

Observations of the S255IR region were carried out with ALMA at two epochs in the compact and extended configurations. Results. We serendipitously detected a new, never predicted, bright maser line at about 349.1 GHz, which most probably represents the CH$_3$OH $14_{1} - 14_{0}$ A$^{- +}$ transition. The emission covers most of the 6.7 GHz methanol maser emission area of almost 1$^{\prime\prime}$ in size and shows a velocity gradient in the same sense as the disk rotation. No variability was found on the time interval of several months. It is classified as Class II maser and probably originates in a ring at a distance of several hundreds AU from the central star.

description: No abstracts are to be cited without prior reference to the author.The Burwood Bank is a large under water plateau situated in the South Atlantic between 53°30’S and 55°S and between the longitude of 55°W and 62°W. It lies between the western extremities of the Scotia Ridge and Southern South America. The Bank is in the path of the Antarctic Circumpolar Current and it gives rise to both branches of the Falklands Current. The area is characterised by an anticylonic gyre which, in conjunction with its local hydrography results in unique fish and cephalopod communities. Stocks of rockcod (Patagonotothen ramsayi) and southern blue whiting (Micromeisistius a. australis) were targeted sporadically in the 60s and 70s by eastern European countries but the area was never fished intensively due to rough fishing grounds. Since the mid 1980’s fishing activity has been restricted to sporadic longlining for the Patagonian toothfish (Dissostichus eleginoides) by two licensed fishing vessels. The Burdwood Bank is the only reproductive area of the species known in the Southwest Atlantic, and because of this the fishery here is prohibited during the spawning season. The western shelf area of the bank, which is situated in Argentinean waters, is a protected area for juvenile toothfish.

description: We study a broad-band X-ray observation by BeppoSAX of the broad-line radio galaxy 3C 120. The primary X-ray continuum is well described by a power law with the photon index of Gamma=1.85+-0.05 and a high-energy break or a cutoff. The obtained e-folding energy of about100-300 keV corresponds to kT of about 50 keV in thermal-Compton models. A soft X-ray excess is found at a statistical significance of >98%$ Our physical best-fit model of the excess is optically-thin emission from an extended plasma (with a luminosity of 2% of the total X-ray luminosity), which interpretation is supported by an independent finding of an extended soft X-ray halo in 3C 120. We find a moderate Compton reflection component together with a moderately broad Fe K alpha line with an equivalent width fully consistent with the strength of reflection, indicating their origin in an optically-thick accretion disk extending relatively close to the central black hole. We observe strong spectral variability during our 2-day observation with Gamma varying from 1.7 to 2.0 and correlated with the soft X-ray flux. The variability is very well modeled by thermal Comptonization in a hot plasma irradiated by a variable UV flux. Both a hot patchy corona outflowing with a mildly relativistic velocity away from a cold disk and a hot inner accretion flow overlapping with the cold disk are viable geometries. The presence of an outflow in the first case and an overlap between the hot and cold phases in the second case are required by energy balance and the observed strength of Compton reflection.

Lattice Coulomb Hamiltonian and Static Color-Coulomb Field

description: The lattice Coulomb-gauge hamiltonian is derived from the transfer matrix of Wilson's Euclidean lattice gauge theory, wherein the lattice form of Gauss's law is satisfied identically. The restriction to a fundamental modular region (no Gribov copies) is implemented in an effective hamiltonian by the addition of a "horizon function" $G$ to the lattice Coulomb-gauge hamiltonian. Its coefficient $γ_0$ is a thermodynamic parameter that ultimately sets the scale for hadronic mass, and which is related to the bare coupling constant $g_0$ by a "horizon condition". This condition determines the low-momentum behavior of the (ghost) propagator that transmits the instantaneous longitudinal color-electric field, and thereby provides for a confinement-like feature in leading order in a new weak-coupling expansion.

description: The technique of non-redundant masking (NRM) transforms a conventional telescope into an interferometric array. In practice, this provides a much better constrained point spread function than a filled aperture and thus higher resolution than traditional imaging methods. Here we describe an NRM data reduction pipeline. We discuss strategies for NRM observations regarding dithering patterns and calibrator selection. We describe relevant image calibrations and use example Large Binocular Telescope datasets to show their effects on the scatter in the Fourier measurements. We also describe the various ways to calculate Fourier quantities, and discuss different calibration strategies. We present the results of image reconstructions from simulated observations where we adjust prior images, weighting schemes, and error bar estimation. We compare two imaging algorithms and discuss implications for reconstructing images from real observations. Finally, we explore how the current state of the art compares to next generation Extremely Large Telescopes.

description: We consider the effect of vertical outflows on the mean-field dynamo in a thin disk. These outflows could be due to winds or magnetic buoyancy. We analyse both two-dimensional finite-difference numerical solutions of the axisymmetric dynamo equations and a free-decay mode expansion using the thin-disk approximation. Contrary to expectations, a vertical velocity can enhance dynamo action, provided it is not too strong. In the nonlinear regime this can lead to super-exponential growth of the magnetic field.

Anomaly free U(1) chiral gauge theories on a two dimensional torus

description: We consider anomaly free combinations of chiral fermions coupled to $U(1)$ gauge fields on a 2D torus first in the continuum and then on the lattice in the overlap formulation. Both in the continuum and on the lattice, when the background consists of sufficiently large constant gauge potentials the action induced by the fermions varies significantly under certain singular gauge transformations. ``Ruling away'' such discontinuities cannot be justified in the continuum framework and does not naturally fit on the lattice. Complete gauge invariance in the continuum can be restored in some models by choosing special boundary conditions for the fermions. Evidence is presented that gauge averaging the overlap phases in these models produces correct continuum results.

description: No abstracts are to be cited without prior reference to the author.Orange roughy (Hoplostethus atlanticus) is a deep-sea species with a centenarian lifespan, which may enable them to withstand prolonged periods of recruitment failure. Most orange roughy stocks have been substantially depleted, and estimating recruitment has therefore become a priority for setting catch quotas. We provide the first direct description of orange roughy nursery grounds, using extensive research survey data from 12,541 bottom trawls and 713 midwater trawls. The juveniles were initially found on the bottom, near known spawning grounds, and towards the shallower end of the species’ depth distribution, in highest densities at 850–900 m. They were not found in midwater, nor in the shallower or deeper bottom tows. As juveniles got larger, the spatial and depth distribution expanded, into both shallower and deeper water, with a skew towards deeper water, such that by the onset of maturation they occurred at relatively high densities from 850–1300 m. Estimates of future recruitment were derived from stratified random trawl surveys of the nursery grounds, after making informed assumptions about selectivity and catchability. Future recruitment on the northeast Chatham Rise from this method was substantially lower than estimated from stock assessment models. The model assumption of constant recruitment was therefore rejected.
Entanglement and Open Systems in Algebraic Quantum Field Theory

description: Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyze entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter's ability to perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard nonrelativistic quantum theory and classical relativistic field theory.

description: We report the discovery of a 40 arcsec long X-ray filament in the core of the cluster of galaxies A1795. The feature coincides with an Halpha+NII filament found by Cowie et al in the early 1980s and resolved into at least 2 U-band filaments by McNamara et al in the mid 1990s. The (emission-weighted) temperature of the X-ray emitting gas along the filament is 2.5-3 keV, as revealed by X-ray colour ratios. The deprojected temperature will be less. A detailed temperature map of the core of the cluster presented. The cD galaxy at the head of the filament is probably moving through or oscillating in the cluster core. The radiative cooling time of the X-ray emitting gas in the filament is about 3x10^8 yr which is similar to the age of the filament obtained from its length and velocity. This suggests that the filament is produced by cooling of the gas from the intracluster medium. The filament, much of which is well separated from the body of the cD galaxy and its radio source, is potentially of great importance in helping to understand the energy and ionization source of the optical nebulosity common in cooling flows.
