description: An exact analytic solution for the dynamics of vortex pairs is obtained for rapid temperature quenches of a superfluid film starting from the line of critical points below the critical temperature $T_{KT}$. An approximate solution for quenches at and above above $T_{KT}$ provides insights into the origin of logarithmic transients in the vortex decay, and are in general agreement with recent simulations of the quenched XY model. These results confirm that there is no "creation" of vortices whose density increases with the quench rate as predicted by the Kibble-Zurek theory, but only monotonic decay of the thermal vortices already present at the initial temperature.

A possible signature of Lense-Thirring precession in dipping and eclipsing neutron-star low-mass X-ray binaries

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Relativistic Lense-Thirring precession of a tilted inner accretion disk around a compact object has been proposed as a mechanism for low-frequency (~0.01-70 Hz) quasi-periodic oscillations (QPOs) in the light curves of X-ray binaries. A substantial misalignment angle (~15-20 degrees) between the inner-disk rotation axis and the compact-object spin axis is required for the effects of this precession to produce observable modulations in the X-ray light curve. A consequence of this misalignment is that in high-inclination X-ray binaries the precessing inner disk will quasi-periodically intercept our line of sight to the compact object. In the case of neutron-star systems this should have a significant observational effect, since a large fraction of the accretion energy is released on or near the neutron-star surface. In this Letter I suggest that this specific effect of Lense-Thirring precession may already have been observed as ~1 Hz QPOs in several dipping/eclipsing neutron-star X-ray binaries.

description: We investigate the Josephson effect in TNT and NTN junctions, consisting of topological (T) and normal (N) phases of semiconductor-superconductor 1D heterostructures in the presence of a Zeeman field. A key feature of our setup is that, in addition to the variation of the phase of the superconducting order parameter, we allow the orientation of the magnetic field to change along the junction. We find a novel magnetic contribution to the Majorana Josephson coupling that permits the Josephson current to be tuned by changing the orientation of the magnetic field along the junction. We also predict that a spin current can be generated by a finite superconducting phase difference, rendering these materials potential candidates for spintronic applications. Finally, this new type of coupling not only constitutes a unique fingerprint for the existence of Majorana bound states but also provides an alternative pathway for manipulating and braiding topological qubits in networks of wires.

description: The absence of time-reversal symmetry is a fundamental property of many nonlinear time series. Here, we propose a new set of statistical tests for time series irreversibility based on standard and horizontal visibility graphs. Specifically, we statistically compare the distributions of time-directed variants of the common complex network measures degree and local clustering coefficient. Our approach does not involve surrogate data and is applicable to relatively short time series. We demonstrate its performance for paradigmatic model systems with known time-reversal properties as well as for picking up signatures of nonlinearity in neuro-physiological data.

description: We exploit a recently found connection between special triple-cut diagrams and tree-level recursive diagrams to derive a general formula capturing the multi-particle factorisation of arbitrary one-loop amplitudes in the ABJM theory. This formula contains certain anomalous contributions which are reminiscent of the so-called non-factorising contributions appearing in the factorisation of one-loop amplitudes in four-dimensional gauge theory. In the second part of the paper we derive a recursion relation for the supercoefficients of one-loop amplitudes in ABJM theory. By applying this recursion relation, any one-loop supercoefficient can be reduced to special triple-cut diagrams involving at least one four-point tree amplitude. In turn, this implies that any one-loop supercoefficient can be derived from tree-level recursive diagrams.

title: Analytical methodologies for solar sail trajectory design
Creators: name: Macdonald, Malcolm
Publisher: name: University of Glasgow
Year: 2005
Subjects: subject: Aerospace engineering.

description: With increased international interest in solar sailing for future science missions comes the requirement to generate algorithms for effective orbit design, manoeuvring and control. Previously unexplained seasonal variations in sail escape times from Earth orbit are explained analytically and corroborated within a numerical trajectory model. Simple blended sail control algorithms are developed which are explicitly independent of time and provide near optimal planetary escape trajectories, while maintaining a safe minimum altitude. It is also shown that the time until escape corresponding to the minimum sail acceleration requirement for shadow free Earth escape is independent of initial altitude. Traditional trajectory optimisation methods are computationally intensive, requiring significant engineering judgement and experience. A new method of blending locally optimal control laws is thus developed for more complex applications. Each control law is prioritised by consideration of how efficiently it will use the solar sail and how far each orbital element is from its target value. The blended, locally optimal sail thrust vector is thus defined to use the sail efficiently, allowing the rapid generation of near-optimal trajectories. The blending method introduced is demonstrated for a complex orbit transfer about Mercury and for two planet-centred station keeping applications. The new method is also demonstrated for three different heliocentric scenarios and is shown to closely match, or even out-perform some existing optimization methods. Furthermore, the method is demonstrated as suitable for rapid mission analysis with an ideal, a non-ideal or optical degradation solar sail force model, while also providing an excellent initial guess for other optimisation methods. The blending algorithms used are explicitly independent of time and as such the control systems are suitable as on-board sail controllers.

description: Resonance fluorescence in the Heitler regime provides access to single photons with coherence well beyond the Fourier transform limit of the transition, and holds the promise to circumvent environment-induced dephasing common to all solid-state systems. Here we demonstrate that the coherently generated single photons from a single self-assembled InAs quantum dot display mutual coherence with the excitation laser on a timescale exceeding 3 seconds. Exploiting this degree of mutual coherence we synthesize near-arbitrary coherent photon waveforms by shaping the excitation laser field. In contrast to post-emission filtering, our technique avoids both photon loss and degradation of the single photon nature for all synthesized waveforms. By engineering pulsed waveforms of single photons, we further demonstrate that separate photons generated coherently by the same laser field are fundamentally indistinguishable, lending themselves to creation of distant entanglement through quantum interference.

description: By integration of generalized BSBM and Brans-Dicke cosmological models, in this article, we investigate the theoretical framework of fine structure constant variation and current cosmic acceleration. We first develop a mathematical formalism to analyse the stability of the model. By employing observational data to constrain the model parameters, phase space is performed and the attractor solutions of the model are detected. We then examine the model against observational data such as observational Hubble parameter dataset and quasar absorption spectra. The results confirms current universe acceleration and also predicts fine structure constant variation. Furthermore, extrapolation of the best fitted model in high redshift ($z> 15$) illustrates a significantly larger variation of fine structure constant in earlier epoch of the universe.

Otherwise, the bulk of its distribution occurs in the upper Great Lakes region, eastern Canada, and from scattered locations in the Appalachian Mountains (Ross & Ricker 1971, DeWalt et al. 2010). Despite numerous attempts to recollect the species from and near the type locality, no new specimens have been found. Consequently, Webb (2002) and DeWalt et al.

Grubbs (2004) stated that although Finni (1973), Bednarik & McCafferty (1977), and Stewart & Stark (2002) each listed A. illinoensis from Indiana, no specific literature records or museum specimens had been found. We present one population from northeastern Indiana and a second from central Indiana ca. 90 km northeast of the type locality.

description: Structural transformations at interfaces are of profound fundamental interest as complex examples of phase transitions in low-dimensional systems. Despite decades of extensive research, no compelling evidence exists for structural transformations in high-angle grain boundaries in elemental systems. Here we show that the critical impediment to observations of such phase transformations in atomistic modeling has been rooted in inadequate simulation methodology. The proposed new methodology allows variations in atomic density inside the grain boundary and reveals multiple grain boundary phases with different atomic structures. Reversible first-order transformations between such phases are observed by varying temperature or injecting point defects into the boundary region. Due to the presence of multiple metastable phases, grain boundaries can absorb significant amounts of point defects created inside the material by processes such as irradiation. We propose a novel mechanism of radiation damage healing in metals which may guide further improvements in radiation resistance of metallic materials through grain boundary engineering.

description: Der Beitrag beschäftigt sich mit der Positionierung und Vermessung von Komponenten für Indoor-Lokalisierungs- und drahtlose Kommunikationssysteme in Industrieumgebungen. Bisher wurden häufig Stativmontagen oder Flugdrohnen zur Positionsveränderung verwendet, die jedoch nicht immer flexibel einsetzbar sind und reproduzierbare Messungen erlauben. Daher wird ein neuartiges Konzept vorgestellt, welches ein mobiles Liftsystem zur automatisierten Positionierung der Komponenten im 3D-Raum nutzt. Das 3D-Liftsystem verfügt über einen horizontal sowie vertikal verfahrbaren Teleskoparm und bietet die Möglichkeit Langzeittests durchzuführen sowie Umgebungsveränderungen aufzuzeichnen. Das Konzept wurde als Fallstudie umgesetzt und im Kontext einer realen Industrieumgebung zur Vermessung von 5G-Komponenten angewendet. Ein Vergleich zu herkömmlichen Positionierungsmethoden anhand verschiedener Eigenschaften zeigt, dass das vorgeschlagene Konzept Eignungskriterien für umfangreiche, langwierige und unterbrechungsfreien Messkampagnen mit 79 % am höchsten erfüllt, während eine Umsetzung mit Stativen und Flugdrohnen nur 64 % bzw. 54 % erreichen.

description: Starting from Feynman's Lagrangian description of quantum mechanics, we propose a method to construct explicitly the propagator for the Wigner distribution function of a single system. For general quadratic Lagrangians, only the classical phase space trajectory is found to contribute to the propagator. Inspired by Feynman's and Vernon's influence functional theory we extend the method to calculate the propagator for the reduced Wigner function of a system of interest coupled to an external system. Explicit expressions are obtained when the external system consists of a set of independent harmonic oscillators. As an example we calculate the propagator for the reduced Wigner function associated with the Caldeira-Legett model.

description: A thin shell finite element approach based on Loop's subdivision surfaces is proposed, capable of dealing with large deformations and anisotropic growth. To this end, the Kirchhoff-Love theory of thin shells is derived and extended to allow for arbitrary in-plane growth. The simplicity and computational efficiency of the subdivision thin shell elements is outstanding, which is demonstrated on a few standard loading benchmarks. With this powerful tool at hand, we demonstrate the broad range of possible applications by numerical solution of several growth scenarios, ranging from the uniform growth of a sphere, to boundary instabilities induced by large anisotropic growth. Finally, it is shown that the problem of a slowly and uniformly growing sheet confined in a fixed hollow sphere is equivalent to the inverse process where a sheet of fixed size is slowly crumpled in a shrinking hollow sphere in the frictionless, quasi-static, elastic limit.

description: Software testing enables the assessment and assurance of software quality. However, writing test cases manually is time-consuming and error-prone. To avoid this, test cases can be generated automatically using Model-based Testing (MBT). MBT derives tests from a test model like a finite state machine (FSM). Such FSMs are often part of specifications, but unfortunately, often only provided as image and not in machine-readable form. Therefore, in this work we present an approach to extract machine-readable representations of FSMs from images automatically using Neural Networks. Additionally, we evaluate the applicability of our approach using a real-world specification to generate test cases from it.

description: A thorough network diagnosis is essential to cutting down the cost of network downtime in heterogeneous, time-sensitive Ethernet networks. It appears that many Time-Sensitive Networking mechanisms do not provide sufficient information about possible error sources, error recognition, or error causes. This paper examines possible symptoms and error sources of Frame Preemption and how to detect them automatically. Moreover, it examines the limitations and functionality of the Scheduled Traffic Anomaly Detection algorithm (STADA) by utilizing a test network. This research provides assistance to manufacturers of industrial automation devices, experts, and network administrators in performing FDD and root-cause analysis for Scheduled Traffic and Frame Preemption faults in Time-Sensitive networks.

description: The edge computing paradigm continues to disrupt areas such as the automation domain where hardware-based implementations, i.e., programmable logic controllers (PLCs), have dominated for decades. The shift to virtualization and data center technologies offers both new opportunities and risks. By providing the first experimental validation of Remote Direct Memory Access (RDMA) over a deterministic IP-based network, we converge the IT and OT domains with a high availability approach for virtualized PLCs. Synchronizing the state of two PLC instances via RDMA provides fault tolerance across multiple data centers and exemplifies the potential of data center technologies for the automation industry. The experimental validation demonstrates the excellent match between the communication requirements of RDMA and the characteristics of the deterministic network. Finally, the need for deterministic acyclic communication in the pursuit of IT/OT convergence is illustrated.

description: The UKs withdrawal from the European Union presents multiple uncertainties for farm management planning. Encouraging growth within the agricultural economy requires some acceptance of risk within farming decision making. This briefing note outlines the results of a survey of 2,494 farmers, crofters and smallholders, run during the summer of 2018, on their approaches towards farming and how this may affect business planning post-Brexit. We find three categories of farmers based on their risk perceptions. Risk averse farmers (39%), risk taking farmers (17%), and risk cautious farmers (44%). Risk taking farmers appear to be more likely to have increased their intensity of production and their level of diversification. In addition they are more likely to have invested in new technologies and new capital. On more environmental led approaches, the differences are less extreme, especially in aspects around woodland expansion which may indicate different motivates towards public good activities. There is a fairly even spread of risk perceptions across farming types, with risk takers more likely to emerge from very large farms, and risk averse farmers from very small farms. Older farmers are more risk averse, and a higher proportion of risk cautious and risk takers are under 45. Only a slightly higher proportion of new entrants are risk takers compared to established farmers. Understanding risk perception is crucial as support systems may change. Risk taking activity can lead to higher levels of investment and therefore increasing on farm efficiencies. On more greener activities there is less evidence. However, whilst risk taking may lead to more sustainable growth, the high level of debt within Scottish farming may support more risk cautious approaches to investment. Nevertheless, supporting farmers away from risk averse behaviours (which compose 39% of the sample) should be encouraged.

description: 3-D astrophysical atmospheres will have random velocity fields. We seek to combine the methods we have developed for solving the 1-D problem with arbitrary flows to those that we have developed for solving the fully 3-D relativistic radiative transfer problem in the case of monotonic flows. The methods developed in the case of 3-D atmospheres with monotonic flows, solving the fully relativistic problem along curves defined by an affine parameter, are very flexible and can be extended to the case of arbitrary velocity fields in 3-D. Simultaneously, the techniques we developed for treating the 1-D problem with arbitrary velocity fields are easily adapted to the 3-D problem. The algorithm we present allows the solution of 3-D radiative transfer problems that include arbitrary wavelength couplings. We use a quasi-analytic formal solution of the radiative transfer equation that significantly improves the overall computation speed. We show that the approximate lambda operator developed in previous work gives good convergence, even neglecting wavelength coupling. Ng acceleration also gives good results. We present tests that are of similar resolution to what has been presented using Monte-Carlo techniques, thus our methods will be applicable to problems outside of our test setup. Additional domain decomposition parallelization strategies will be explored in future work.

description: Following on from the NASA twins’ study, there has been a tremendous interest in the use of omics techniques in spaceflight. Individual space agencies, NASA’s GeneLab, JAXA's ibSLS, and the ESA-funded Space Omics Topical Team and the International Standards for Space Omics Processing (ISSOP) groups have established several initiatives to support this growth. Here, we present recommendations from the Space Omics Topical Team to promote standard application of space omics in Europe. We focus on four main themes: i) continued participation in and coordination with international omics endeavors, ii) strengthening of the European space omics infrastructure including workforce and facilities, iii) capitalizing on the emerging opportunities in the commercial space sector, and iv) capitalizing on the emerging opportunities in human subjects research.

description: The metabolome is the biochemical basis of plant form and function, but we know little about its macroecological variation across the plant kingdom. Here, we used the plant functional trait concept to interpret leaf metabolome variation among 457 tropical and 339 temperate plant species. Distilling metabolite chemistry into five metabolic functional traits reveals that plants vary on two major axes of leaf metabolic specialization—a leaf chemical defense spectrum and an expression of leaf longevity. Axes are similar for tropical and temperate species, with many trait combinations being viable. However, metabolic traits vary orthogonally to life-history strategies described by widely used functional traits. The metabolome thus expands the functional trait concept by providing additional axes of metabolic specialization for examining plant form and function.
On the Relation between Solar Activity and Clear-Sky Terrestrial Irradiance

description: The Mauna Loa Observatory record of direct-beam solar irradiance measurements for the years 1958-2010 is analysed to investigate the variation of clear-sky terrestrial insolation with solar activity over more than four solar cycles. The raw irradiance data exhibit a marked seasonal cycle, extended periods of lower irradiance due to emissions of volcanic aerosols, and a long-term decrease in atmospheric transmission independent of solar activity. After correcting for these effects, it is found that clear-sky terrestrial irradiance typically varies by about 0.2 +/- 0.1% over the course of the solar cycle, a change of the same order of magnitude as the variations of the total solar irradiance above the atmosphere. An investigation of changes in the clear-sky atmospheric transmission fails to find a significant trend with sunspot number. Hence there is no evidence for a yet unknown effect amplifying variations of clear-sky irradiance with solar activity.

description: 5G networks are currently adapted more and more in industrial applications due to their high-speed data transfer, low latency, and increased capacity. To address growing demands and increase cost-effectiveness, the idea of shared 5G campus networks has emerged, akin to co-working spaces known from office environments. This is especially beneficial for small and medium enterprises in industrial parks looking to incorporate 5G technology into their automation needs. In order to ensure the network can meet the diverse application requirements of all companies involved, a simulation platform called Virtual Automation Network Simulation (VANSIM) is under development. VANSIM aims to allow companies to validate and test the feasibility and compatibility of shared 5G networks pre- and post-installation from the perspective of the automation applications. This paper focuses on validating this simulation platform for passive environmental influences by comparing its results to real-world measurements.

description: We report magnetoresistance measurements through Nb films having a periodic thickness modulation. The cylinder shaped large-thickness regions of the sample, which form a square lattice, act as repulsive centers for the superconducting vortices. For low driving currents along one of the axes of the square lattice, the resistivity $ρ$ increases monotonously with increasing magnetic field $B$ and the $ρ$--$B$ characteristics are approximately piecewise linear. The linear $ρ$ vs $B$ segments change their slope at matching fields where the number of vortices is an integer or a half integer times the number of protruding cylinders in the sample. Numerical simulations allow us to associate the different segments of linear magnetoresistance to different vortex-flow regimes, some of which are dominated by the propagation of discommensurations (kinks).

description: In communication systems, high data rates combined with low end-to-end latencies are prime necessities for allowing a wide variety of applications, e.g., streaming of video and data or in context of IoT Systems. In contrast, applications in Industry Automation require deterministic end-to-end latencies with guaranteed deadlines. In communication systems, data rates, reliability and the achievable end-to-end latency are often a trade-off (e.g., due to buffering of data, and overall systems-design). Further, most communication systems are optimized for high data rates only, yet, deterministic end-to-end latencies are required for most Industrial Use-Cases, which are still not considered well enough in research and standardization. In this paper we focus on low-latency communication, and, outline the importance of this research aspect. Consequently, we propose a novel Mini-Slot approach for 5G and beyond communication systems to tackle the problem of minimizing uplink- and downlink communication latencies in cellular networks under load. First evaluations of our approach in context of a feasibility study show promising results. As comparison in realistic experiments with Rel-15-based 5G Commercial off-the-shelf ( COTS ) hardware, a baseline scenario (unoptimized) shows a maximum latency up to 49.04 ms. In contrast to that, our novel mini-slot approach allows to lower the maximum end-to-end communication latency to 15.51 ms. This way, our mini-slot approach constitutes as enabler for low-latency communication by using Rel-15-based 5G COTS and User Equipment ( UE ) hardware for industrial use-cases, without the need to wait for further releases of 5G systems.
