Order and chaos in the local disc stellar kinematics induced by the Galactic bar

Subjects: subject: Astrophysics (astro-ph)

description: (Abridged) The Galactic bar causes a characteristic splitting of the disc phase space into regular and chaotic orbit regions which is shown to play an important role in shaping the stellar velocity distribution in the Solar neighbourhood. A detailed orbital analysis within an analytical 2D rotating barred potential reveals that this splitting is mainly dictated by the value of the Hamiltonian H and the bar induced resonances. Test particle and N-body simulations reveal how the decoupled evolution of the disc distribution function in the two kind of regions and the process of chaotic mixing lead to overdensities in the H>H_12 chaotic part of the u-v velocity distributions outside corotation, where H_12 is the effective potential at the Lagrangian points L_1/2. In particular, for realistic space positions of the Sun near or slightly beyond the outer Lindblad resonance and if u is defined positive towards the anti-centre, the eccentric quasi-periodic orbits trapped around the stable x1(1) orbits - i.e. the bar-aligned closed orbits which asymptotically become circular at larger distances - produce a broad u<0 regular arc in velocity space extending within the H>H_12 zone, whereas the corresponding u>0 region appears as an overdensity of chaotic orbits forced to avoid that arc. This chaotic overdensity provides an original interpretation, distinct from the anti-bar elongated quasi-periodic orbit interpretation proposed by Dehnen (2000), for the prominent stream of high asymmetric drift and predominantly outward moving stars clearly emerging from the Hipparcos data. The effects of spiral arms and of molecular clouds are also briefly discussed within this context.

description: Artificial lattices have served as a platform to study the physics of unconventional superconductivity. We study semiconductor artificial graphene -- a honeycomb superlattice imposed on a semiconductor heterostructure -- which hosts the Dirac physics of graphene but with a tunable periodic potential strength and lattice spacing, allowing control of the strength of the electron-electron interactions. We demonstrate a new mechanism for superconductivity due to repulsive interactions which requires a strong lattice potential and a minimum doping away from the Dirac points. The mechanism relies on the Berry phase of the emergent Dirac fermions, which causes oppositely moving electron pairs near the Dirac points to interfere destructively, reducing the Coulomb repulsion and thereby giving rise to an effective attraction. The attractive component of the interaction is enhanced by a novel antiscreening effect which, in turn, increases with doping; as a result there is a minimum doping beyond which superconducting order generically ensues. The dominant superconducting state exhibits a spatially modulated gap with chiral $p$-wave symmetry. Microscopic calculations suggest that the possible critical temperatures are large relative to the low carrier densities, for a range of experimentally realistic parameters.

description: Weak turbulence of magnetohydrodynamic (MHD) waves in strongly magnetized plasma is studied when the thermal pressure is less than the magnetic field pressure. In this situation the main nonlinear mechanism is the resonance scattering of fast magneto-acoustic and Alfvenic waves on slow magneto-acoustic waves. As a result, the former waves serve as the high-frequency waves with respect to the latter ones so that the total number of HF waves - an adiabatic invariant - conserves additionally. In the weak turbulence regime this invariant is shown to generate the Kolmogorov type spectrum with a constant flux of HF waves towards large-scale region. In the short-wave region another Kolmogorov spectrum can be realized with a constant energy flux. The explicit angle dependences for both types of turbulent spectra are found for the propagation angles close to the direction of a mean magnetic field.

description: As a major agricultural subsector, milk production plays an important role in the EU 28. Political decisions such as the abolition of the milk quota system in 2015, highly volatile milk prices, high bargaining power of retailers and fierce international competition have led to challenges for both farmers and dairies and have created a need to improve competitiveness. Furthermore, the dairy sector is increasingly subject to societal demands for higher animal welfare and ecological standards. The concept of sustainability in the form of a production standard can be seen as a means for both dairy farmers and dairies to gain competitive advantages and meet stakeholders’ demands. Farmers’ willingness to participate in a sustainability standard is a key factor for its successful implementation. One attractive target group for such a standard are future-oriented farmers who plan to stay in dairy farming in the long run. This study, therefore, focuses on future-oriented dairy farmers and investigates their willingness to participate in a comprehensive sustainability standard. A hierarchical agglomerative cluster analysis is conducted to identify different groups based on their willingness to participate. 211 farmers can be categorized into three different clusters: ‘halfhearted sustainability proponents’, ‘highly dedicated sustainability proponents’ and ‘profit-oriented sustainability refusers’. Further analysis provides insights into the determinants of farmers’ willingness to participate in a sustainability standard. The results of this study provide manifold starting points for deriving managerial implications for the successful implementation of sustainability standards in European dairy farming

description: The doping of semiconductor materials is a fundamental part of modern technology, but the classical approaches have in many cases reached their limits both in regard to achievable charge carrier density, as well as mobility. Modulation doping, a mechanism that exploits the energy band alignment at an interface between two materials to induce free charge carriers in one of them, has been shown to circumvent the mobility restriction. Due to an alignment of doping limits by intrinsic defects, however, the carrier density limit cannot be lifted using this approach. Here we present a novel doping strategy using defects in a wide band gap material to dope the surface of a second semiconductor layer of dissimilar nature. We show that by depositing an insulator on a semiconductor material, the conductivity of the layer stack can be increased by seven orders of magnitude, without the necessity of high temperature processes or epitaxial growth. This approach has the potential to circumvent limits to both carrier mobility and density, opening up new possibilities in semiconductor device fabrication, particularly for the emerging field of oxide thin film electronics.

It remains still far from being clearly understood what mechanisms spread metals over Mpc scales from the parent galaxies, whether metals are homogeneously distributed in the intergalactic medium (IGM), how metallicity of the IGM does evolve. These questions are briefly addressed in this review.

description: Three-body non-additive forces in systems of three spin-polarized alkali atoms (Li, Na, K, Rb and Cs) are investigated using high-level ab initio calculations. The non-additive forces are found to be large, especially near the equilateral equilibrium geometries. For Li, they increase the three-atom potential well depth by a factor of 4 and reduce the equilibrium interatomic distance by 0.9 A. The non-additive forces originate principally from chemical bonding arising from sp mixing effects.

description: We investigate operational probabilistic theories where the pure states of every system are the vertices of a simplex. A special case of such theories is that of classical theories, i.e. simplicial theories whose pure states are jointly perfectly discriminable. The usual Classical Theory satisfies also local discriminability. However, simplicial theories---including the classical ones---can violate local discriminability, thus admitting of entangled states. First, we prove sufficient conditions for the presence of entangled states in arbitrary probabilistic theories. Then, we prove that simplicial theories are necessarily causal, and this represents a no-go theorem for conceiving non-causal classical theories. We then provide necessary and sufficient conditions for simplicial theories to exhibit entanglement, and classify their system-composition rules. We conclude proving that, in simplicial theories, an operational formulation of the superposition principle cannot be satisfied, and that---under the hypothesis of $n$-local discriminability---no mixed state admits of a purification. Our results hold also in the general case where the sets of states fail to be convex.

description: Marine big data are characterized by a large amount and complex structures, which bring great challenges to data management and retrieval. Based on the GeoSOT Grid Code and the composite index structure of the MongoDB database, this paper proposes a spatio-temporal grid index model (STGI) for efficient optimized query of marine big data. A spatio-temporal secondary index is created on the spatial code and time code columns to build a composite index in the MongoDB database used for the storage of massive marine data. Multiple comparative experiments demonstrate that the retrieval efficiency adopting the STGI approach is increased by more than two to three times compared with other index models. Through theoretical analysis and experimental verification, the conclusion could be achieved that the STGI model is quite suitable for retrieving large-scale spatial data with low time frequency, such as marine big data.
Probing the faint end of the Galaxy luminosity function at z=3 with Ly-alpha emission

description: We present spectroscopic observations obtained with the ESO Very Large Telecope (VLT) of seven candidate Ly-alpha emitting galaxies in the field of the radio quiet Q1205-30 at z=3.04 previously detected with deep narrow band imaging. Based on equivalent widths and limits on line ratios we confirm that all seven objects are Ly-alpha emitting galaxies. Deep images also obtained with the VLT in the B and I bands show that five of the seven galaxies have very faint continuum fluxes (I(AB) approx. 26.8 and B(AB) approx. 27.3). The star formation rates of these seven galaxies estimated from the rest-frame UV continuum around 2000AA, as probed by the I-band detections, as well as from the Ly-alpha luminosities, are 1-4 M_sun yr^{-1}. This is 1-3 orders of magnitude lower than for other known populations of star-forming galaxies at similar redshifts (the Lyman-Break galaxies and the sub-mm selected sources). The inferred density of the objects is high, 16+-4 per arcmin^2 per unit redshift. This is consistent with the integrated luminosity function for Lyman-Break galaxies down to R=27 if the fraction of Ly-alpha emitting galaxies is approx. 70% at the faint end of the luminosity function. However, if this fraction is 20% as reported for the bright end of the luminosity function then the space density in this field is significantly larger (by a factor of 3.5) than expected from the luminosity function for Lyman-Break galaxies in the HDF-North. This would be an indication that at least some radio quiet QSOs at high redshift reside in overdense environments or that the faint end slope of the high redshift luminosity function has been underestimated. These observations show that Ly-alpha emission is an efficient method by which to probe the faint end of the luminosity function at high redshifts.

description: We study the structure of Milky Way (MW)- and cluster-sized halos in a Lambda Cold Dark Matter (CDM) cosmology with self-interacting (SI) dark particles. The cross section per unit of particle mass has the form sigma = sig_0(1/v_100)^alpha, where sig_0 is a constant in units of cm^2/gr and v_100 is the relative velocity in units of 100 km/s. Different values for sigma with alpha= 0 or 1 were used. For small values of sigma = const. (sig_0<0.5), the core density of the halos at z=0 is typically higher at a given mass for lower values of sig_0 or, at a given sig_0, for lower masses. For values of sig_0 as high as 3.0, the halos may undergo the gravothermal catastrophe before z=0. When alpha = 1, the core density of cluster- and MW-sized halos is similar. Using sigma = 0.5-1.0x(1/v_100), our predictions agree with the central densities and the core scaling laws of halos both inferred from the observations of dwarf and LSB galaxies and clusters of galaxies. The cumulative Vmax-functions of subhalos in MW-sized halos with (sig_0,alpha) = (0.1,0.0), (0.5,0.0) and (0.5,1.0) agree roughly with observations (luminous satellites) for Vmax > 30 km/s, while at Vmax = 20 km/s the functions are a factor 5-8 higher, similar to the CDM predictions. The halos with SI have slightly more specific angular momentum at a given mass shell and are rounder than their CDM counterparts. We conclude that the introduction of SI particles with sigma \propto 1/v_100 may remedy the cuspy core problem of the CDM cosmogony, while the subhalo population number remains similar to that of the CDM halos.

description: Phytocapping is a sustainable landfill cover technology that utilises a vegetated soil cover to create a hydraulic barrier for compacted waste. The vegetation in phytocaps offers various environmental, ecological, and social benefits, including providing habitat for local flora and fauna and contributing to natural green spaces that mitigate air pollution and the urban heat island effect. Additionally, phytocap vegetation employs soil bioengineering to reinforce the soil, enhancing slope stability. Little research has focused on critical phytocapping design parameters, namely soil compaction and vegetation design, which significantly affect hydrological performance, as well as vegetation growth and survival. This thesis aims to inform landfill designers about optimal phytocap design by configuring soil compaction and vegetation design, using coal overburden material. The research comprises five stages that address the objectives. [...]

We show that $H$ admits nontrivial self-adjoint extensions (SAE) in a given range of values of the parameter $g$. The $ζ$-functions of these operators present poles which depend on $g$ and, in general, do not coincide with half an integer (they can even be irrational). The corresponding residues depend on the SAE considered.

description: Skyrmions have become one of the most visited topics during the last decade in condensed matter physics. In this work, and by means of analytical calculations and micromagnetic simulations, we explore the effect of the magnetostatic field generated by a magnetic tip on the stability of skyrmions. Our results show that the interaction energy between the tip and the skyrmion plays a fundamental role in the stabilization of Néel skyrmions confined in nanodisks, allowing its nucleation and annihilation, and also providing precise control of its size and polarity. Based on our results, we propose a very simple and cyclic method to nucleate and annihilate skyrmions, as well as to control their polarity and chirality. This proposal could open new possibilities for logic devices taking advantage of all the degrees of freedom that skyrmionic textures have.

description: The aromatic nature of the structure of lignin enables its use as a natural and sustainable hard carbon precursor. Upon carbonisation, lignin-derived hard carbon has shown potential as a sodium-ion battery anode. In this study, we have utilised coaxial electrospinning to produce nanofibers, which undergo stabilisation and carbonisation, to analyse the influence of carbon morphology on sodium-ion storage mechanisms. Various nanostructures have been tailored to produce intricate core/shell structures with varying degrees of porosity to allow controlled Na diffusion and storage.

description: While the demand for machine learning (ML) applications is booming, there is a scarcity of data scientists capable of building such models. Automatic machine learning (AutoML) approaches have been proposed that help with this problem by synthesizing end-to-end ML data processing pipelines. However, these follow a best-effort approach and a user in the loop is necessary to curate and refine the derived pipelines. Since domain experts often have little or no expertise in machine learning, easy-to-use interactive interfaces that guide them throughout the model building process are necessary. In this paper, we present Visus, a system designed to support the model building process and curation of ML data processing pipelines generated by AutoML systems. We describe the framework used to ground our design choices and a usage scenario enabled by Visus. Finally, we discuss the feedback received in user testing sessions with domain experts.

description: In its original formulation the Krein matrix was used to locate the spectrum of first-order star-even polynomial operators where both operator coefficients are nonsingular. Such operators naturally arise when considering first-order-in-time Hamiltonian PDEs. Herein the matrix is reformulated to allow for operator coefficients with nontrivial kernel. Moreover, it is extended to allow for the study of the spectral problem associated with quadratic star-even operators, which arise when considering the spectral problem associated with second-order-in-time Hamiltonian PDEs. In conjunction with the Hamiltonian-Krein index (HKI) the Krein matrix is used to study two problems: conditions leading to Hamiltonian-Hopf bifurcations for small spatially periodic waves, and the location and Krein signature of small eigenvalues associated with, e.g., $n$-pulse problems. For the first case we consider in detail a first-order-in-time fifth-order KdV-like equation. In the latter case we use a combination of Lin's method, the HKI, and the Krein matrix to study the spectrum associated with $n$-pulses for a second-order-in-time Hamiltonian system which is used to model the dynamics of a suspension bridge.

description: The aim of the study was to analyze from the regional and comparative standpoints some major indices of the world market and trade of vegetables, essential in the population diet as the obligatory and irreplaceble groupe of commodities. Special reference was given to trends, i.e. output, dynamics and structure of production, trade and consumption of the products analyzed. In addition, regions, i.e. countries known to be the largest producers but no less importers and exporters of vegetables were determined. Significant differences were registered between regions which may be attributed to a large number of natural, social and economic factors. Both quantitative and qualitative research methods of the market were used in the analysis of the relationship and the level of impact of the factors influencing changes and trends of the incidences investigated.

description: About 70 years ago, machines and chemistry played an important role for human beings. That was the realization of harmonious life between man and machine. Now, the theme is realization of harmonious life between man and environment. We can witness irregularities regarding proper nourishment of population which affects the health and well-being of people in the world. Highly developed countries have problems in the area of rational consumption and health safety of food. In this paper authors analyze the actual condition of the problems concerning organic production in the world and EU. Also, they focus their attention on ecomarketing mix. Low wages and increased cost of living have contributed to continuous negative trends regarding nourishment in Serbia. Authors analyze market chances and barriers in Serbia in accordance with organic production. This paper will provide theoretical and practical contribution for those responsible to carry out adequate actions to improve organic production in Serbia.

description: I review recent progress in understanding the arrest and flow behaviour of colloidal glasses, based on mode coupling theory (MCT) and related approaches. MCT has had notable recent successes in predicting the re-entrant arrest behaviour of colloids with short range attractions. Developments based upon it offer important steps towards calculating, from rational foundations in statistical mechanics, nonlinear flow parameters such as the yield stress of a colloidal glass. An important open question is why MCT works so well.

description: This paper investigates the state of poverty and its determinants covering the period 1994 -1997 on the basis of a panel data that covers 3,000 households both from urban as well as rural areas. The main findings show that poverty on the average declined during this period mainly due to increase in per capita income, particularly in rural areas. The extent of the reduction in poverty would have been much stronger if not for the worsening of income inequality. Profile of poverty shows that poverty in Ethiopia affects urban as well as rural areas at comparable scale and intensity. At the household level, factors such as human and physical capital bear a strong influence on the probability of being poverty. Factors such as access to markets, resources and urbanization affect greatly on the chance of being in poverty.

description: This paper investigates the determinants and dynamics of poverty in urban areas in Ethiopia. The results show that urban poverty is quite high in Ethiopia, indicating the Seriousness of the problem. We observed high fluctuations in living standards mainly Driven by fluctuations in food prices, particularly those of cereals. Thus, price Stabilization policies form important ingredients for fighting poverty. Factors that affect the dynamics of poverty are mainly education of head of the household and size of the household. Policies that promote human capital and control of population growth reduce greatly the probability of falling into poverty.
title: Neurological Mechanisms Underlying Exercise-Induced Fatigue in Multiple Sclerosis

Publisher: name: Griffith University

Subjects: subject: performance fatigability
subject: multiple sclerosis
subject: neurophysiology

description: Fatigue is reported as the most debilitating symptom in people with Multiple Sclerosis (MS). Greater levels of exercise-induced fatigue have been documented in people with MS compared to healthy controls across a wide range of fatiguing contraction protocols. Existing literature suggests that exercise-induced fatigue in MS may be related to a decline in neural drive to the muscle, however, the underlying neurophysiological mechanisms remain unclear. Many investigations have examined the motor system in MS during fatiguing contractions however, much disparity exists due to the variability of techniques to assess neural drive as well as duration and intensity of the contraction protocols employed. This Thesis consists of three experiments which examine the neurophysiological mechanisms that contribute to the objective measure of fatigue (performance fatigability) in people with MS. Electromyography (EMG), motor nerve stimulation (MNS), and transcranial magnetic stimulation (TMS) of the motor cortex were used to assess different levels of the motor system during fatiguing contractions of the upper limb in people with MS compared to healthy controls.

description: A next generation Gamma Ray Burst (GRB) mission to follow the upcoming Swift mission is described. The proposed Energetic X-ray Imaging Survey Telescope, EXIST, would yield the limiting (practical) GRB trigger sensitivity, broad-band spectral and temporal response, and spatial resolution over a wide field. It would provide high resolution spectra and locations for GRBs detected at GeV energies with GLAST. Together with the next generation missions Constellation-X, NGST and LISA and optical-survey (LSST) telescopes, EXIST would enable GRBs to be used as probes of the early universe and the first generation of stars. EXIST alone would give ~10-50" positions (long or short GRBs), approximate redshifts from lags, and constrain physics of jets, orphan afterglows, neutrinos and SGRs.
