description: The dissolution process of star clusters is rather intricate for theory. We investigate it in the context of chaotic dynamics. We use the simple Plummer model for the gravitational field of a star cluster and treat the tidal field of the Galaxy within the tidal approximation. That is, a linear approximation of tidal forces from the Galaxy based on epicyclic theory in a rotating reference frame. The Poincaré surfaces of section reveal the effect of a Coriolis asymmetry. The system is non-hyperbolic which has important consequences for the dynamics. We calculated the basins of escape with respect to the Lagrangian points $L_1$ and $L_2$. The longest escape times have been measured for initial conditions in the vicinity of the fractal basin boundaries. Furthermore, we computed the chaotic saddle for the system and its stable and unstable manifolds. The chaotic saddle is a fractal structure in phase space which has the form of a Cantor set and introduces chaos into the system.

description: For the quadratic family $f_{c}(z) = z^2+c$ with $c$ in the exterior of the Mandelbrot set, it is known that every point in the Julia set moves holomorphically. Let $\hat{c}$ be a semi-hyperbolic parameter in the boundary of the Mandelbrot set. In this paper we prove that for each $z = z(c)$ in the Julia set, the derivative $dz(c)/dc$ is uniformly $O(1/\sqrt{|c-\hat{c}|})$ when $c$ belongs to a parameter ray that lands on $\hat{c}$. We also characterize the degeneration of the dynamics along the parameter ray.

description: Humans will launch spacecraft that travel at an appreciable fraction of the speed of light. Spacecraft traffic will be tracked by radar. Scattering of pulsed electromagnetic fields by an object in uniform translational motion at relativistic speed may be computed using the frame-hopping technique. Pulse scattering depends strongly on the velocity, shape, orientation, and composition of the object. The peak magnitude of the backscattered signal varies by many orders of magnitude depending on whether the object is advancing toward or receding away from the source of the interrogating signal. The peak magnitude of the backscattered signal goes to zero as the object recedes from the observer at a velocity very closely approaching light speed, rendering the object invisible to the observer. The energy scattered by an object in motion may increase or decrease relative to the energy scattered by the same object at rest. Both the magnitude and sign of the change depend on the velocity of the object, as well as on its shape, orientation, and composition. In some cases, the change in total scattered energy is greatest when the object is moving transversely to the propagation direction of the interrogating signal, even though the Doppler effect is strongest when the motion is parallel or antiparallel to the propagation direction.

description: In this paper we develop a framework for integrating real-time software modules that comprise a reconfigurable multi-sensor based system. Our framework is based on the proposed concept of a global database of state information through which real-time software modules exchange information. This methodology allows the development and integration of reusable software in a complex multiprocessing environment. A reconfigurable sensor-based control system consists of many software modules, each of which can be modelled using a simplified version of a port automaton. Our new state variable table mechanism can be used in both statically and dynamically reconfigurable systems, and it is completely processor independent. Individual modules may also be combined into larger modules to aid in building large systems, and to reduce bus and CPU utilization. An efficient implementation of the state variable table mechanism, which has been integrated into the ChimeraII Real-Time Operating System, is also described.

description: Real-time visual feedback is an important capability that many robotic systems must possess if these systems are to operate successfully in dynamically varying and/or uncalibrated environments. An eye-in-hand system is a common technique for providing camera motion to increase the working region of a visual sensor. Although eye-in-hand robotic systems have been well-studied, several deficiencies in proposed systems make them inadequate for actual use. Typically, the systems fail if manipulators pass through singularities or joint limits. Objects being tracked can be lost if the objects become defocused, occluded, or if features on the objects lie outside the field of view of the camera. In this paper, a technique is introduced for integrating a visual tracking strategy with dynamically determined sensor placement criteria. This allows the system to automatically determine, in real-time, proper camera motion for tracking objects successfully while accounting for the undesirable, but often unavoidable, characteristics of camera-lens and manipulator systems. The sensor placement criteria considered include focus, field-of-view, spatial resolution, manipulator configuration, and a newly introduced measure calledresolvability. Experimental results are presented.

Long reads

description: Long read technologies have revolutionized de novo genome assembly by generating contigs orders of magnitude longer than that of short read assemblies. Although assembly contiguity has increased, it usually does not reconstruct a full chromosome or an arm of the chromosome, resulting in an unfinished chromosome level assembly. To increase the contiguity of the assembly to the chromosome level, different strategies are used which exploit long range contact information between chromosomes in the genome. We develop a scalable and computationally efficient scaffolding method that can boost the assembly contiguity to a large extent using genome-wide chromatin interaction data such as Hi-C. We demonstrate an algorithm that uses Hi-C data for longer-range scaffolding of de novo long read genome assemblies. We tested our methods on the human and goat genome assemblies. We compare our scaffolds with the scaffolds generated by LACHESIS based on various metrics. Our new algorithm SALSA produces more accurate scaffolds compared to the existing state of the art method LACHESIS.

description: We present the relativistic calculation of the beta-decay of tritium in a hadron model. The elementary particle treatment of the transition 3H -> 3He + e^- + nu_e is performed in analogy with the description of the beta-decay of neutron. The effects of higher order terms of hadron current and nuclear recoil are taken into account in this formalism. The relativistic Kurie function is derived and presented in a simple form suitable for the determination of neutrino masses from the shape of the endpoint spectrum. A connection with the commonly used Kurie function is established.

description: Research investigating mammography screening has often reported low mammography self-efficacy and breast cancer fear contribute to underutilization of mammography. This study aimed to examine the reliability and validity of Champion’s Mammography Self-efficacy Scale (CMSS) and Champion’s Breast Cancer Fear Scale (CBCFS) in a sample of Iranian women. The adapted instruments were administered to a community sample of 482 women aged 40 years or older. They inhibited in Sanandaj, Iran. Cronbach’s α coefficients, item-total, and test-retest correlations were used to assess the reliability of the scales. Confirmatory factor analysis was applied to assess construct validity. The α coefficients for the Farsi 14-item CMSS and 8-item BCFS were .87 and.95, respectively. In terms of the CMSS confirmatory factor analysis, the proportion of x 2/df was 2.4, Comparative Fit Index (CFI) = 0.93, Tucker Lewis Index (TLI) = 0.96 providing a strong fit to the data induced by two-factor model. With regard to CBCFS, x 2/df was 86.33, CFI =0.99, and TLI =0.99 supporting one-factor model. The CMSS and CBCFS exhibited strong initial psychometric properties; therefore, they are recommended to understand women’s breast cancer screening behaviors better.

 Salticid spider S. larae is a Palearctic species (Platnick, 2014). In the first description D. Logunov (2000) characterized this species as Euro-Siberian temperate species distributed in Fennoscandia and Estonia, through the middle Urals and Siberia, eastward to Sakhalin (Logunov, 2000). Also S. larae was registered in Belgium (Keer van et al., 2010), Sweden (Logunov, 2000; Almquist, 2006), Germany (Keer van et al., 2010; Staudt, 2011), Netherlands (Vogels, 2012). Notably, the specimens of the species were mainly found in dry open biotopes: semi-shrubby meadow, low-lying meadow, sheep-grazed wet heath, dry heath etc. (Logunov, 2000; Vogels 2012). Both specimens were found on sphagnum of the wet bog and in the shaded pine-birch forest. Although the species habitat is vast, the finds of S. larae specimens are rare and small in numbers (Logunov, 2000; Vogels, 2012). In Belgium, Germany and Netherlands S. larae was characterized as a rare species (Vogels, 2012).

description: Planning is a complex reasoning task that is well suited for the study of improving performance and knowledge by learning, i.e. by accumulation and interpretation of planning experience. PRODIGY is an architecture that integrates planning with multiple learning mechanisms. Learning occurs at the planner’s decision points and integration in PRODIGY is achieved via mutually interpretable knowledge structures. This article describes the PRODIGY planner, briefly reports on several learning modules developed earlier along the project, and presents in more detail two recently explored methods to learn to generate plans of better quality. We introduce the techniques, illustrate them with comprehensive examples, and show prelimary empirical results. The article also includes a retrospective discussion of the characteristics of the overall PRODIGY architecture and discusses their evolution within the goal of the project of building a large and robust integrated planning and learning system.
Energy spectrum of electromagnetic normal modes in dissipative media: modes between two metal half spaces

description: The energy spectrum of the electromagnetic normal modes plays a central role in the theory of the van der Waals and Casimir interaction. In dissipative media it appears as if there are distinct normal modes with complex valued energies. The summation of the zero-point energies of these modes render a complex valued result. Using the contour integration, resulting from the use of the generalized argument principle, gives a real valued and different result. We resolve this contradiction and show that the spectrum of true normal modes form a continuum with real frequencies. We illustrate the problem in connection with the van der Waals interaction between two metal half spaces.

description: Despite being one of the weakest dimers in nature, low-spectral-resolution Voyager/IRIS observations revealed the presence of (H$_2$)$_2$ dimers on Jupiter and Saturn in the 1980s. However, the collision-induced H$_2$-H$_2$ opacity databases widely used in planetary science (Borysow et al., 1985; Orton et al., 2007; Richard et al., 2012) have thus far only included free-to-free transitions and have neglected the contributions of dimers. Dimer spectra have both fine-scale structure near the S$(0)$ and S$(1)$ quadrupole lines (354 and 587 cm$^{-1}$, respectively), and broad continuum absorption contributions up to $\pm50$ cm$^{-1}$ from the line centres. We develop a new ab initio model for the free-to-bound, bound-to-free and bound-to-bound transitions of the hydrogen dimer for a range of temperatures (40-400 K) and para-hydrogen fractions (0.25-1.0). The model is validated against low-temperature laboratory experiments, and used to simulate the spectra of the giant planets. The new collision-induced opacity database permits high-resolution (0.5-1.0 cm$^{-1}$) spectral modelling of dimer spectra near S$(0)$ and S$(1)$ in both Cassini Composite Infrared Spectrometer (CIRS) observations of Jupiter and Saturn, and in Spitzer Infrared Spectrometer (IRS) observations of Uranus and Neptune for the first time. Furthermore, the model reproduces the dimer signatures observed in Voyager/IRIS data near S$(0)$ (McKellar et al., 1984) on Jupiter and Saturn, and generally lowers the amount of para-H$_2$ (and the extent of disequilibrium) required to reproduce IRIS observations.

As a consequence, it is shown that any axially symmetric suitable weak solution $u$, belonging to $L_{\infty}(0,T;\dot{B}_{\infty,\infty}^{-1})$, is smooth.

description: The transition from command-line interfaces to graphical interfaces has resulted in programs that are easier to learn and use, but harder to automate and reuse. Another transition is now underway, to HTML interfaces hosted by a web browser. To help users automate HTML interfaces, we propose the browser-shell, a web browser that integrates a command interpreter into the browser’s Location box. The browser-shell’s command language is designed for extracting and manipulating HTML and text, and commands can also invoke local programs. Command input is drawn from the current browser page, and command output is displayed as a new page. The browser-shell brings to web browsing many advantages of the Unix shell, including scripting web services and creating pipelines of web services and local programs. A browser-shell also allows legacy command-line programs to be wrapped with an HTML/CGI interface that is graphical but still scriptable, and offers a new shell interaction model, different from the conventional type-script model, which may improve usability in some respects.
Effect of edge roughness in graphene nanoribbon transistors

description: The effects of edge irregularity and mixed edge shapes on the characteristics of graphene nanoribbon transistors are examined by self-consistent atomistic simulations based on the non-equilibrium Green's function formalism. The minimal leakage current increases due to the localized states induced in the band gap, and the on-current decreases due to smaller quantum transmission and the self-consistent electrostatic effect in general. Although the ratio between the on-current and minimal leakage current decreases, the transistor still switches even in the presence of edge roughness. The variation between devices, however, can be large, especially for a short channel length.

description: In this study, the temperature dependence of elastic constants $C_{11}$, $C_{33}$, $C_{\rm E} = (C_{11}-C_{12})/2$, $C_{66}$ and $C_{44}$ of the iron-based superconductor Ba(Fe$_{1-x}$Co$_{x}$)$_{2}$As$_{2}$ (0 $\leqq x \leqq$ 0.245) have been measured. This system shows a large elastic softening in $C_{66}$ towards low temperatures. In addition to $C_{66}$, which originates from orthorhombic structural fluctuation, the samples near the optimal concentration show remarkable structural fluctuation in $C_{11}$ and $C_{33}$ elastic modes, which correspond to $Γ_{1}$ (C4) symmetry. It suggests the existence of diverse fluctuations in this system. Gr{\" u}neisen parameters were analyzed under some assumptions for structural and magnetic transition temperatures. Results showed that the Gr{\" u}neisen parameters for the inter-plane strain are remarkably enhanced toward the QCP, while those for the in-plane stress tend to turn down near the QCP. Gr{\" u}neisen parameters for the superconducting transition are anisotropic and shows remarkable Co-concentration dependence, suggesting that the in-plane isotropic compression and inter-layer elongation enhance the superconductivity. The correlation of Gr{\" u}neisen parameters between $T_{\rm S}$, $T_{\rm N}$ and $T_{\rm sc}$ shows $c$-axis elongation and its relevant role in the emergence of superconductivity in this system.

description: We argue that a genuine image of the black hole viewed by a distant observer is not its shadow, but a more compact event horizon image probed by the luminous matter plunging into black hole. The external border of the black hole shadow is washed out by radiation from matter plunging into black hole and approaching the event horizon. This effect will crucially influence the results of future observations by the Event Horizon Telescope. We show that gravitational lensing of the luminous matter plunging into black hole provides the possibility for visualization of the event horizon. The lensed image of the event horizon is formed by the highly red-shifted photons emitted by the plunging matter very near the black hole event horizon and detected by a distant observer. The resulting event horizon image is a gravitationally lensed projection on the celestial sphere of the whole black hole event horizon sphere. Seemingly, black holes are the unique objects in the Universe which may be viewed by distant observers at once from both the front and back sides.

description: We consider model order reduction of a nonlinear cable-mass system modeled by a 1D wave equation with interior damping and dynamic boundary conditions. The system is driven by a time dependent forcing input to a linear mass-spring system at one boundary. The goal of the model reduction is to produce a low order model that produces an accurate approximation to the displacement and velocity of the mass in the nonlinear mass-spring system at the opposite boundary. We first prove that the linearized and nonlinear unforced systems are well-posed and exponentially stable under certain conditions on the damping parameters, and then consider a balanced truncation method to generate the reduced order model (ROM) of the nonlinear input-output system. Little is known about model reduction of nonlinear input-output systems, and so we present detailed numerical experiments concerning the performance of the nonlinear ROM. We find that the ROM is accurate for many different combinations of model parameters.

description: We construct evolutionary models of the populations of AGN and supermassive black holes, in which the black hole mass function grows at the rate implied by the observed luminosity function, given assumptions about the radiative efficiency and the Eddington ratio. We draw on a variety of recent X-ray and optical measurements to estimate the bolometric AGN luminosity function and compare to X-ray background data and the independent estimate of Hopkins et al. (2007) to assess remaining systematic uncertainties. The integrated AGN emissivity closely tracks the cosmic star formation history, suggesting that star formation and black hole growth are closely linked at all redshifts. Observational uncertainties in the local black hole mass function remain substantial, with estimates of the integrated black hole mass density ρ_BH spanning the range 3-5.5x10^5 Msun/Mpc^3. We find good agreement with estimates of the local mass function for a reference model where all active black holes have efficiency \eps=0.065 and L_bol/L_Edd~0.4. In this model, the duty cycle of 10^9 Msun black holes declines from 0.07 at z=3 to 0.004 at z=1 and 0.0001 at z=0. The decline is shallower for less massive black holes, a signature of "downsizing" evolution in which more massive black holes build their mass earlier. The predicted duty cycles and AGN clustering bias in this model are in reasonable accord with observational estimates. If the typical Eddington ratio declines at z<2, then the "downsizing" of black hole growth is less pronounced. Matching the integrated AGN emissivity to the local black hole mass density implies \eps=0.075 (ρ_BH/4.5x10^5 Msun/Mpc^3)^{-1} for our standard luminosity function estimate (25% higher for Hopkins et al.'s), lower than the values \eps=0.16-0.20 predicted by MHD simulations of disk accretion.

description: The research funding organisations (RFOs) of PRO-Ethics are implementing ten pilots to explore participatory approaches in RFO activities. While adding value by obtaining relevant inputs from citizens and stakeholders not normally included in such processes, these pilots also enhance the RFOs' competence with participation processes and inform future activities. In this policy brief, we share important learnings from our pilot experiences that can benefit all research and innovation funding agencies with a wish to apply participatory methods.
title: Theatrical living : responsive lives which manifest God's loving presence and ways

description: God is revealed through Scripture and the Incarnation as desiring to establish loving relationships with others beyond the Trinity. In the beginning he did so by creating human beings, and making himself, his desires, and his ways known to them. He chose to do so through particular actions and encounters in history which involved various forms of embodied manifestation, and led up to the supreme manifestation: the enfleshing of Jesus. Following on from the acts of Jesus which perfectly manifested God and his ways to the world in the flesh, human creatures created in the image of God and united to Christ are also called and gifted by God to manifest God’s presence, activity, and ways in this world by using their bodies to live faithfully and responsively to the leading of the Spirit. In order to investigate and demonstrate these claims, Part I of the thesis examines a selection of precedent-setting events chronicled in the Old Testament in which God manifested his presence and ways to people in a variety of circumstances. Part II is concerned with a theological examination of God’s manifestations and the roles people can and should play in these manifestations. It begins by engaging with reflections on the subject from the early church fathers Irenaeus, Athanasius, and Augustine; and, in keeping with the Reformed approach taken in the thesis generally, this is followed by in-depth treatments of Reformer John Calvin and Reformed theologian Karl Barth on the revelation, manifestation, and proclamation of God by people in this world. Having substantiated the claim that how people live is significant and of concern to God as it can impinge upon his ongoing desire to make himself and his ways known, Part III is designed to provide a fuller understanding of some of the meaning and significance conveyed by bodily expressions in human interactions with an eye towards seeking ways to live more faithfully to God. It identifies the theatre, particularly improvisational theatre, as a laboratory for understanding human living, and so explores the insights of theatre practitioners into everyday living; while also considering the work of philosophers of language and sociologists who do the same. Through this spotlight on the theatricality of life the case is made for attempting to live responsively, in keeping with improvisational actors, in ways that are faithful to God and which can serve to aid those united to Christ as they seek to make God known to others.

description: In this paper, we apply machine learning methods to study phase transitions in certain statistical mechanical models on the two dimensional lattices, whose transitions involve non-local or topological properties, including site and bond percolations, the XY model and the generalized XY model. We find that using just one hidden layer in a fully-connected neural network, the percolation transition can be learned and the data collapse by using the average output layer gives correct estimate of the critical exponent $ν$. We also study the Berezinskii-Kosterlitz-Thouless transition, which involves binding and unbinding of topological defects---vortices and anti-vortices, in the classical XY model. The generalized XY model contains richer phases, such as the nematic phase, the paramagnetic and the quasi-long-range ferromagnetic phases, and we also apply machine learning method to it. We obtain a consistent phase diagram from the network trained with only data along the temperature axis at two particular parameter $Δ$ values, where $Δ$ is the relative weight of pure XY coupling. Besides using the spin configurations (either angles or spin components) as the input information in a convolutional neural network, we devise a feature engineering approach using the histograms of the spin orientations in order to train the network to learn the three phases in the generalized XY model and demonstrate that it indeed works. The trained network by using system size $L\times L$ can be used to the phase diagram for other sizes ($L'\times L'$, where $L'\ne L$) without any further training.

Aharonov-Bohm ring with a side-coupled atomic cluster: magneto-transport and the selective switching effect

description: We report electronic transmission properties of a tight binding Aharonov-Bohm ring threaded by a magnetic flux, to one arm of which a finite cluster of atoms has been attached from one side. we demonstrate that, by suitably choosing the number of scatterers in each arm of the quantum ring and, by decoupling the ring from the atomic cluster, the transmission across the ring can be completely blocked when the flux threading the ring becomes equal to half the fundamental flux quantum. A transmission resonance then occurs immediately as the coupling between the ring and the impurity cluster is switched 'on'. It is shown that the delta-like transmission resonances occur precisely at the eigenvalues of the side coupled chain of atoms.Thw 'switching' effect can be observed either for all the eigenvalues of the isolated atomic cluster, or for a selected set of them, depending on the number of scatterers in the arms of the ring. The ring-dot coupling can be gradually increased to suppress the oscillations in the magneto-transmission completely. However, the suppression can lead either to a complete transparency or no transmission at all, occasionally accompanied by a reversal of phase at special values of the magnetic flux.

description: We performed an empirical study to explore how closely well-known, open source C programs follow the safe C standards for integer behavior, with the goal of understanding how difficult it is to migrate legacy code to these stricter standards. We performed an automated analysis on fifty-two releases of seven C programs (6 million lines of preprocessed C code), as well as releases of Busybox and Linux (nearly one billion lines of partially-preprocessed C code). We found that integer issues, that are allowed by the C standard but not by the safer C standards, are ubiquitous—one out of four integers were inconsistently declared, and one out of eight integers were inconsistently used. Integer issues did not improve over time as the programs evolved. Also, detecting the issues is complicated by a large number of integers whose types vary under different preprocessor configurations. Most of these issues are benign, but the chance of finding fatal errors and exploitable vulnerabilities among these many issues remains significant. A preprocessor-aware, tool-assisted approach may be the most viable way to migrate legacy C code to comply with the standards for secure programming.
Dendritic-Inspired Processing Enables Bio-Plausible STDP in Compound Binary Synapses

description: Brain-inspired learning mechanisms, e.g. spike timing dependent plasticity (STDP), enable agile and fast on-the-fly adaptation capability in a spiking neural network. When incorporating emerging nanoscale resistive non-volatile memory (NVM) devices, with ultra-low power consumption and high-density integration capability, a spiking neural network hardware would result in several orders of magnitude reduction in energy consumption at a very small form factor and potentially herald autonomous learning machines. However, actual memory devices have shown to be intrinsically binary with stochastic switching, and thus impede the realization of ideal STDP with continuous analog values. In this work, a dendritic-inspired processing architecture is proposed in addition to novel CMOS neuron circuits. The utilization of spike attenuations and delays transforms the traditionally undesired stochastic behavior of binary NVMs into a useful leverage that enables biologically-plausible STDP learning. As a result, this work paves a pathway to adopt practical binary emerging NVM devices in brain-inspired neuromorphic computing.

Instance-Based Question Answering: A Data Driven Approach

description: Anticipating the availability of large question-answer datasets, we propose a principled, data-driven Instance-Based approach to Question Answering. Most question answering systems incorporate three major steps: classify questions according to answer types, formulate queries for document retrieval, and extract actual answers. Under our approach, strategies for answering new questions are directly learned from training data. We learn models of answer type, query content, and answer extraction from clusters of similar questions. We view the answer type as a distribution, rather than a class in an ontology. In addition to query expansion, we learn general content features from training data and use them to enhance the queries. Finally, we treat answer extraction as a binary classification problem in which text snippets are labeled as correct or incorrect answers. We present a basic implementation of these concepts that achieves a good performance on TREC test data.
A Computational Study of Vertical Partial Gate Carbon Nanotube FETs

description: A vertical partial gate carbon nanotube (CNT) field-effect transistor (FET), which is amenable to the vertical CNT growth process and offers the potential for a parallel CNT array channel, is simulated using a self-consistent atomistic approach. We show that the underlap between the gate and the bottom electrode (required for isolation between electrodes) is advantageous for transistor operation because it suppresses ambipolar conduction. A vertical CNTFET with a gate length that covers only 1/6 of the channel length has a much smaller minimum leakage current than one without underlap, while maintaining comparable on current. Both n-type and p-type transistor operations with balanced performance metrics can be achieved on a single partial gate FET by using proper bias schemes. Even with a gate underlap, it is demonstrated that increasing the CNT diameter still leads to a simultaneous increase of on current and minimum leakage current. Along with a partial gate, the simulated transistor features a significant amount of air between the surface of the channel CNT and the gate insulator, as is caused by the vertical CNT growth process. Filing this pore with a high-k insulator is shown to have the potential to decrease the on current, due to electrostatic phenomena at the source-channel contact.
