description: In this work, we study the dynamics of particles around Bennu. The goal is to understand the stability, evolution, and final outcome of the simulated particles around the asteroid. According to the results, the particle sizes can be divided into two main groups depending on their behavior. Particles smaller than a centimeter are quickly removed from the system by solar radiation pressure, while the dynamics of particles larger than a few centimeters is dominated by the gravitational field of Bennu. Because of its shape and spin period, Bennu has eight equilibrium points around it. The structure of the phase space near its equatorial surface is directly connected to these equilibrium points. Therefore, we performed numerical simulations to obtain information about the orbital evolution near the equilibrium points. The results show that most of the particles larger than a few centimeters fall in the equatorial region close to the Kingfisher area or close to the region diametrically opposite to it. In contrast, almost none of these particles fall in the equatorial region close to the Osprey area. In addition, we also performed computational experiments considering a spherical cloud of particles initially orbiting Bennu. Most of the particles in prograde orbits fall on the surface within our integration period, which was limited to 1.14 years. The particles preferentially fall near high-altitude regions at low equatorial latitudes and close to the north pole. The mid-latitudes are those more depleted of falls, as in the Nightingale and Sandpiper areas.

description: In this paper, we study quantum phase transitions and magnetic properties of a one-dimensional spin-1/2 Gamma model, which describes the off-diagonal exchange interactions between edge-shared octahedra with strong spin-orbit couplings along the sawtooth chain. The competing exchange interactions between the nearest neighbors and the second neighbors stabilize semimetallic ground state in terms of spinless fermions, and give rise to a rich phase diagram, which consists of three gapless phases. We find distinct phases are characterized by the number of Weyl nodes in the momentum space, and such changes in the topology of the Fermi surface without symmetry breaking produce a variety of Lifshitz transitions, in which the Weyl nodes situating at $k=π$ interchange from type I to type II. A coexistence of type-I and type-II Weyl nodes is found in phase II. The information measures including concurrence, entanglement entropy and relative entropy can effectively signal the second-order transitions. The results indicate that the Gamma model can act as an exactly solvable model to describe Lifshitz phase transitions in correlated electron systems.

Uniform Approximation Property of Implicit Methods for a Stiff Family of Differential Equations

Subjects: Implicit Euler

description: Stiff systems are characterized by the presence of multiple time scales where the fast scales are stable.  The presence of a scaling factor, ?, in the system creates slow and fast components which lead  to the distinct time scales. Conventional stability analysis shows that numerical solutions using explicit Taylor  methods need a step size that is smaller than the fast time scale to get a stable solution. With implicit Taylor  methods, the step size can be larger in comparison without affecting the stability of the solution.  Most of the analysis done in regard to stiff systems tends to fix the step size and look at the stability of the  numerical solution as the number of steps goes to infinity. This thesis presents a new form of analysis for numerical methods for stiff systems. We examine the numerical solutions over  a finite time interval as the step size goes to zero over an entire range of the scaling factors ??1.  We show that uniform convergence is a better indicator than unconditional stability for the effectiveness of a  numerical solution to a stiff system. We investigate the uniform convergence of the numerical solutions to the true solution for a family of systems. We begin with an analysis of a family of scalar linear real equations to show that explicit Euler and trapezoidal methods are not  uniformly convergent. Using Dini's theorem, we can show that the numerical solution using an implicit Taylor's method  converges uniformly to the true solution as the step size decreases. In addition, we were able to show that when  using the implicit Euler method, the uniform convergence is of the order O(h) where h is the step size. We then extend the results to higher dimensions to show that for a family of linear non-stiff systems, the explicit and implicit Euler converge uniformly. In addition, we show that the implicit Euler method converges uniformly for a family of stiff  two-dimensional linear systems.

description: This paper describes a finite state machine for adaptive mission control of mini aerial vehicles. The purpose of a finite state machine is to support mission control during aerial inspection of high voltage transmission lines and insulators independently from environmental and other conditions. One of the basic application of our mini aerial vehicle research is inspection of high voltage transmission lines during its load mode. Around high voltage transmission lines and towers generating a strong electromagnetic field. An electromagnetic fields can be influence negatively to autonomous flight and mission control should be predicted such us situation to avoid possible accident.


Moreover environmental and weather condition always unpredictable and mission control have to adapt for various type of additional constrains which can be make problem for pre-defined mission map and trajectory.


Therefore, it needs to develop mission control for autonomous flight with an adaptive option or capability. Such mission control provides less workload and safety guarantee for the inspection team during the process.

In a research study for the country of Mongolia the advantages of a drone delivery system are shown and the unique challenges such as temperature, elevation and range are discussed to choose a suitable system design for countries with enormous size and low population. Airplane like drones with their wider distances seem to be the most promising solution to connect rural areas to the medical logistics network.

Gelächter im stummen Kode
Creators: name: Foret, Martin
Publisher: name: Zeitschrift für Semiotik
Year: 2018

description: Abstract. The paper explores ways of representing smiles and laughter in comics. First a semiotic delimitation of comics is proposed, which can be understood as a code that operates in one sensory channel and simulates receptive synaesthesia. The roots of the expression of smiles within the pictorial code are found in the work of the cartoonists of the 18th and 19th centuries who created early examples of sequential art, thus establishing the tradition of later picture stories and comics. The paper then focuses on how the acoustic dimensions of laughter are represented by typographical means in comics, for example by using graphical conventions of lettering and font design. Different types of smiles and laughter are demonstrated by illustrative examples from a range of genres and styles, from the ligne claire through distinctive cartoon drawings to realistic artwork. The results are discussed in the broader context of the expression of emotions in comics.


Zusammenfassung. Der Artikel untersucht die Darstellung von Lachen und Lächeln im Comic. Eingangs wird eine semiotische Abgrenzung des Comics als eigenständiger Kode vorgeschlagen, der im einkanaligen Medium operiert und eine rezeptive Synästhesie simuliert. Die Wurzeln der Darstellung des Lächelns im Bildkode werden bei den Karikaturisten des 18. und 19. Jahrhunderts verortet, die auch Bildsequenzen schufen, welche später die Tradition der Bildergeschichten und Comics einleiteten. Anschließend wird die akustische Dimension des Lachens fokussiert. Sie wird im Comic-Kode durch typographische Mittel repräsentiert, die auch andere Arten nonverbalen vokalen Verhaltens darstellen und Bedeutungen von verbalen Äußerungen präzisieren und modifizieren können. Die untersuchte Thematik wird anhand von Comicbeispielen demonstriert, die unterschiedlichen Comicgenres und -stilen (von der ligne claire bis zur realistischen Darstellung) angehören. Abschließend werden die Ergebnisse im Kontext der Erforschung von Emotionsdarstellungen im Comic diskutiert.

description: A convex programming problem in a conic form is a minimization of a linear function $\langle c, x\rangle$ over the intersection of an affine space $\{x\in \mathbb{R}^n:\;Ax=b\}$ and a convex cone $K$. In this thesis, we study two broad subclasses of convex programming problems with $K$ having special structure. We treat \emph{homogeneous} programming problems. These are convex programming problems in which $K$ is a homogeneous cone. These problems are more general than well-studied semi-definite or symmetric programming problems. We explain the key steps of Vinberg's classification of homogeneous cones in terms of so-called $T$-algebras, and discuss some properties of a $T$-algebraic barrier associated with $K$. We also consider two alternative constructions of homogeneous cones by means of Siegel domains, and provide a new expression for an \emph{optimal} dual self-concordant barrier for $K$ using the dual construction of Rothaus. A self-concordant barrier is \emph{optimal} if it has the smallest parameter among all self-concordant barriers for $K$. It is important for a barrier to have the smallest possible parameter $\theta$, since $\theta$ enters directly into the complexity estimates for interior-point methods. We give a simplified self-concordance proof for the primal barrier of Guler and Tuncel, and consider several examples. The class of \emph{hyperbolic} programming problems is discussed in the thesis as well. These are conic problems with $K$ being a hyperbolicity cone corresponding to some homogeneous hyperbolic polynomial. We provide descriptions of hyperbolicity cones and their derivative relaxations. We discuss the three-dimensional Lax's theorem, which states that any hyperbolic polynomial of three variables can be written as a determinant of a linear combination of $m\times m$ symmetric matrices. This is a very important theorem since it implies semidefinite representability of any hyperbolicity cone in three dimensions. We show that the Lax's theorem is a powerful and unifying tool by applying it in the proofs of various important results in interior-point methods and convex analysis, and by providing some interesting connections with other branches of mathematics. Finally, the thesis deals with variational problems in quasi-Newton methods. We consider variational problems associated with popular DFP and BFGS updates, and obtain these updates in a very simple manner. Our approach is coordinate free; we eliminate symmetry constraints imposed on the updates by working directly in the space of symmetric matrices. We consider the dual problems. A novel feature of our work is that we construct several new variational problems whose optimal solutions coincide with quasi-Newton update matrices. These new variational problems may be useful in suggesting new quasi-Newton methods in the future.

description: Zusammenfassung. Mit Umberto Eco hat die Semiotik einen der originellsten Zeichentheoretiker und zugleich einen Zeichen-setzenden Intellektuellen verloren. Dies ist mehr als eine Metapher: Ecos Analysen zeitgenössischer Kulturphänomene gingen so weit, dass er durch sie die betreffenden Kulturen veränderte. Er nahm als einer der ersten die Popkultur des späten zwanzigsten Jahrhunderts vom Krimi bis zum Comic unter die (semiotische) Lupe und wurde damit schließlich selbst zu einem Teil der Gegenwartskultur. Glaubt man gewissen Rankings, dann war Eco, der verschmitzte Analytiker der Massenkultur, gegen Ende seines Lebens ein weltweiter Popstar der Wissenschaft wie Chomsky oder Dawkins. Der Nachruf auf Umberto Eco stellt – ausgehend von der Erstveröffentlichung einer Karikatur Ecos, die als humoristischer Kommentar zu Kommunikationstheorien gelesen werden kann – wichtige Entwicklungslinien der Semiotik Umberto Ecos vor.

description: There is a need for a nonacceptable symptom state to indicate when a patient with knee or hip osteoarthritis exhibits symptoms severe enough to warrant total joint replacement (TJR).  A previous study using logistic regression and ROC curve analysis was unable to determine pain and functional disability cut points leading to a TJR recommendation.  Using the datasets from the previous study, classification trees were used to identify predictors and cut points of those predictors leading to a TJR recommendation.  From the analysis, a patient's quality of life and joint space narrowing appeared to be the most important predictors, out of those included in the analysis, of a surgeon's recommendation for TJR.  Further research and analysis is needed to determine if the generated classification trees accurately predict a surgeon's recommendation for TJR.

Elevation of D-dimer (1596,17 μgr/L; < 500 μgr/L threshold to exclude venous thromboembolism) and IL-6 (130 pgr/mL, normal value < 5.9 pgr/mL) were found as well. She was negative for Legionella and Streptococcus pneumonia; she was tested and found positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Because of the rapid deterioration of the clinical condition, the patient required mechanical ventilation and was admitted to intensive care.

Luminous Blue Variables as the progenitors of supernovae with quasi-periodic radio modulations

Subjects: subject: Astrophysics (astro-ph)

description: The interaction between supernova ejecta and circumstellar matter, arising from previous episodes of mass loss, provides us with a means with which to constrain the progenitors of supernovae. Radio observations of a number of supernovae show quasi-periodic deviations from a strict power-law decline at late times. Although several possibilities have been put forward to explain these modulations, no single explanation has proven to be entirely satisfactory. Here we suggest that Luminous Blue Variables undergoing S-Doradus type variations give rise to enhanced phases of mass loss which are imprinted on the immediate environment of the exploding star as a series of density enhancements. The variations in mass loss arise from changes in the ionization balance of Fe, the dominant ion that drives the wind. With this idea, we find that both the recurrence timescale of the variability, as well as the amplitude of the modulations are in line with the observations. Our scenario thus provides a natural, single-star explanation for the observed behaviour that is, in fact, expected on theoretical grounds.

description: Boundary theories of static bulk topological phases of matter are obstructed in the sense that they cannot be realized on their own as isolated systems. The obstruction can be quantified/characterized by quantum anomalies, in particular when there is a global symmetry. Similarly, topological Floquet evolutions can realize obstructed unitary operators at their boundaries. In this paper, we discuss the characterization of such obstructions by using quantum anomalies. As a particular example, we discuss time-reversal symmetric boundary unitary operators in one and two spatial dimensions, where the anomaly emerges as we gauge the so-called Kubo-Martin-Schwinger (KMS) symmetry. We also discuss mixed anomalies between particle number conserving U(1) symmetry and discrete symmetries, such as C and CP, for unitary operators in odd spatial dimensions that can be realized at the boundaries of topological Floquet systems in even spatial dimensions.

Vibration isolation active control techniques and testing in a micro-gravity environment
Creators: name: Boulet, Jason
Publisher: name: University of British Columbia
Year: 2009

description: Since orbitting space stations do not provide a perfect micro-gravity environment, vibration isolation techniques must be employed for sensitive experiments, such as crystal growing. A non-contact approach using magnetic levitation for active vibration isolation has been developed previously that can be used in all micro-gravity situations. Using advanced controller techniques, it should be possible to lower the stiffness of the magnetic coupling below levels achievable by PID control. This thesis examines controlling magnetic levitation (MAGLEV) for improved vibration isolation on Earth and in a micro-gravity environment. Lorentz forces are used to levitate a large platform holding the application in an experimental system using this MAGLEV technology. This technology is described and two designs of it's application are presented. Vibration control techniques are investigated, with and Q-parameterization algorithms explained and employed in active control in a normal gravity environment. A smaller magnetically levitated wrist device is then described and employed in a coarse-fine approach to isolating acceleration disturbances in the microgravity environment provided by NASA's DC-9 performing parabolic flights. Results of the testing done on the flight is given and analyzed.

description: Global climate change has had a drastic impact on our environment. Previous study showed that pest disaster occured from global climate change may cause a tremendous number of trees died and they inevitably became a factor of forest fire. An important portent of the forest fire is the condition of forests. Aerial image-based forest analysis can give an early detection of dead trees and living trees. In this paper, we applied a synthetic method to enlarge imagery dataset and present a new framework for automated dead tree detection from aerial images using a re-trained Mask RCNN (Mask Region-based Convolutional Neural Network) approach, with a transfer learning scheme. We apply our framework to our aerial imagery datasets,and compare eight fine-tuned models. The mean average precision score (mAP) for the best of these models reaches 54%. Following the automated detection, we are able to automatically produce and calculate number of dead tree masks to label the dead trees in an image, as an indicator of forest health that could be linked to the causal analysis of environmental changes and the predictive likelihood of forest fire.

description: Gender imbalance in information technology in general, and Free/Open Source Software specifically, is a well-known problem in the field. Still, little is known yet about the large-scale extent and long-term trends that underpin the phenomenon. We contribute to fill this gap by conducting a longitudinal study of the population of contributors to publicly available software source code. We analyze 1.6 billion commits corresponding to the development history of 120 million projects, contributed by 33 million distinct authors over a period of 50 years. We classify author names by gender and study their evolution over time.We show that, while the amount of commits by female authors remains low overall, there is evidence of a stable long-term increase in their proportion over all contributions, providing hope of a more gender-balanced future for collaborative software development.

We consider the low-energy Hamiltonian which is mapped into a $QED_3$ Lagrangian of spinons. We compare the dynamically generated mass to the one obtained by means of an average site occupation constraint.

description: Micron-size self-propelling particles are often proposed as synthetic models for biological microswimmers, yet they lack internally regulated adaptation, which is central to the autonomy of their biological counterparts. Conversely, adaptation and autonomy can be encoded in larger-scale soft-robotic devices, but transferring these capabilities to the colloidal scale remains elusive. Here, we create a new class of responsive microswimmers, powered by induced-charge electrophoresis, which can adapt their motility to external stimuli via an internal feedback. Using sequential capillary assembly, we fabricate deterministic colloidal clusters comprising soft thermoresponsive microparticles, which, upon spontaneous reconfiguration, induce motility changes, such as adaptation of the clusters' propulsion velocity and reversal of its direction. We rationalize the response in terms of a coupling between self-propulsion and variations of particle shape and dielectric properties. Harnessing those allows for strategies to achieve local dynamical control with simple illumination patterns, revealing exciting opportunities for the development of new tactic active materials.

description: We study the theory of scattering for the Maxwell-Schr"odinger system in space dimension 3, in the Coulomb gauge. We prove the existence of modified wave operators for that system with no size restriction on the Schr"odinger and Maxwell asymptotic data and we determine the asymptotic behaviour in time of solutions in the range of the wave operators. The method consists in partially solving the Maxwell equations for the potentials, substituting the result into the Schr"odinger equation, which then becomes both nonlinear and nonlocal in time. The Schr"odinger function is then parametrized in terms of an amplitude and a phase satisfying a suitable auxiliary system, and the Cauchy problem for that system, with prescribed asymptotic behaviour determined by the asymptotic data, is solved by an energy method, thereby leading to solutions of the original system with prescribed asymptotic behaviour in time. This paper is the generalization of a previous paper with the same title. However it is entirely selfcontained and can be read without any previous knowledge of the latter.

description: We study the black hole's shadow for Schwarzschild - de Sitter and Kerr - de Sitter metrics with the contribution of the cosmological constant Λ. Based on the reported parameters of the M87* black hole shadow we obtain constraints for the $Λ$ and show the agreement with the cosmological data. It is shown that, the coupling of the Λ-term with the spin parameter reveals peculiarities for the photon spheres and hence for the shadows. Within the parametrized post-Newtonian formalism the constraint for the corresponding Λ-determined parameter is obtained.

Modelling light-cone distribution amplitudes from non-relativistic bound states

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We calculate light-cone distribution amplitudes for non-relativistic bound states, including radiative corrections from relativistic gluon exchange to first order in the strong coupling constant. We distinguish between bound states of quarks with equal (or similar) mass, m_1 ~ m_2, and between bound states where the quark masses are hierarchical, m_1 >> m_2. For both cases we calculate the distribution amplitudes at the non-relativistic scale and discuss the renormalization-group evolution for the leading-twist and 2-particle distributions. Our results apply to hard exclusive reactions with non-relativistic bound states in the QCD factorization approach like, for instance, (B_c -> eta_c l nu) or (e^+ e^- -> J/psi eta_c). They also serve as a toy model for light-cone distribution amplitudes of light mesons or heavy B and D mesons, for which certain model-independent properties can be derived. In particular, we calculate the anomalous dimension for the B meson distribution amplitude phi_B^-(w) in the Wandzura-Wilczek approximation and derive the according solution of the evolution equation at leading logarithmic accuracy.

description: Understanding how galaxies cease to form stars represents an outstanding challenge for galaxy evolution theories. This process of "star formation quenching" has been related to various causes, including Active Galactic Nuclei (AGN) activity, the influence of large-scale dynamics, and the environment in which galaxies live. In this paper, we present the first results from a follow-up of CALIFA survey galaxies with observations of molecular gas obtained with the APEX telescope. Together with EDGE survey CARMA observations, we collect $^{12}$CO observations that cover approximately one effective radius in 472 CALIFA galaxies. We observe that the deficit of galaxy star formation with respect to the star formation main sequence (SFMS) increases with the absence of molecular gas and with a reduced efficiency of conversion of molecular gas into stars, in line with results of other integrated studies. However, by dividing the sample into galaxies dominated by star formation and galaxies quenched in their centres (as indicated by the average value of the H$α$ equivalent width), we find that this deficit increases sharply once a certain level of gas consumption is reached, indicating that different mechanisms drive separation from the SFMS in star-forming and quenched galaxies. Our results indicate that differences in the amount of molecular gas at a fixed stellar mass are the primary driver for the dispersion in the SFMS, and the most likely explanation for the start of star-formation quenching. However, once a galaxy is quenched, changes in star formation efficiency drive how much a retired galaxy separates in star formation rate from star-forming ones of similar masses. In other words, once a paucity of molecular gas has significantly reduced star formation, changes in the star formation efficiency are what drives a galaxy deeper into the red cloud, retiring it.

description: Die Digitalisierung bietet Möglichkeiten zur besseren Gestaltung von Arbeit und ihren Bedingungen, wodurch sowohl Beschäftigte als auch Unternehmen (z. B. im Sinne einer Optimierung der Produktivität) profitieren kön­nen. Durch Änderungen der Arbeitsorganisation und -gestaltung ergeben sich Auswirkungen für die Beschäftigten, insbesondere wenn durch die Digitalisierung Möglichkeiten zur Erweiterung der zeitlichen Arbeitsflexibilität entstehen und Grenzen zwischen Privat- und Arbeitsleben verschwimmen. Alle diese Aspekte können sich auf physische und psychische Belastungen auswirken. Des­halb stellt sich die Frage, wie die digitale Transformation von Unternehmen umgesetzt werden sollte, um die zunehmende Integration von Privat- und Arbeitsleben so zu gestalten, dass sowohl die Beschäftigten als auch die Betriebe profitieren und negative Auswirkungen ver­mieden werden. Hierfür stellen die Autoren ausgewählte Studienergebnisse zur Nutzung der Digitalisierung für das betriebliche Produktivitäts­management in der deutschen Metall- und Elek­tro­industrie vor. Der Schwerpunkt liegt auf den Wechselwirkungen zwischen Digita­li­sie­rung und Produktivitätsmanagement und deren Auswirkungen auf die Beschäftigten. Ab­schlie­ßend nennen die Autoren Handlungs­empfehlungen für die Gestaltung der Digitalisierung.

description: We examine whether the fact that QCD is chirally invariant at short distances necessarily leads to the prediction that hadrons form approximate parity doublets, as has been recently put forward by Glozman and collaborators. We show that this is not the case, and we exhibit some of the pitfalls of trying to link the operator product expansion to the hadron spectrum. We illustrate our arguments within a model for scalar and pseudo-scalar mesons used recently by Shifman to argue for parity doubling. We find that, whatever the experimental situation may be, there is no theoretical basis for parity doubling based on the use of the operator product expansion.
