description: Die über dem letztinterglazialen Boden (Parabraunerde bzw. pseudovergleyte Parabraunerde) folgenden würmzeitlichen äolischen Sedimente können durch kennzeichnende Bodenhorizonte in 3 Abschnitte (Alt-, Mittel- und Jungwürm) gegliedert werden. Charakteristisch für das Altwürm sind Humuszonen, für das Mittelwürm neben einigen „Naßböden" braune Verlehmungszonen bis zu einer Mächtigkeit von 1,1 m und für das Jungwürm mehrere schwach ausgebildete, geringmächtige Verbraunungszonen und „Naßböden". Den wichtigsten Leithorizont des Jungwürms bildet das Kärlicher Tuffbändchen, das in jüngster Zeit auch in Nordhessen aufgefunden wurde. Abschließend wird das in Hessen aufgestellte Gliederungsschema mit den Würmlöß-Gliederungen in anderen Teilen Europas verglichen und eine Parallelisierung versucht.

description: We present exact expressions for the Sagnac effect of Goedel's Universe. For this purpose we first derive a formula for the Sagnac time delay along a circular path in the presence of an arbitrary stationary metric in cylindrical coordinates. We then apply this result to Goedel's metric for two different experimental situations: First, the light source and the detector are at rest relative to the matter generating the gravitational field. In this case we find an expression that is formally equivalent to the familiar nonrelativistic Sagnac time delay. Second, the light source and the detector are rotating relative to the matter. Here we show that for a special rotation rate of the detector the Sagnac time delay vanishes. Finally we propose a formulation of the Sagnac time delay in terms of invariant physical quantities. We show that this result is very close to the analogous formula of the Sagnac time delay of a rotating coordinate system in Minkowski spacetime.

description: The concept of perpendicular shape anisotropy spin-transfer torque magnetic random-access memory (PSA-STT-MRAM) consists in increasing the storage layer thickness to values comparable to the cell diameter, to induce a perpendicular shape anisotropy in the magnetic storage layer. Making use of that contribution, the downsize scalability of the STT-MRAM may be extended towards sub-20 nm technological nodes, thanks to a reinforcement of the thermal stability factor $Δ$. Although the larger storage layer thickness improves $Δ$, it is expected to negatively impact the writing current and switching time. Hence, optimization of the cell dimensions (diameter, thickness) is of utmost importance for attaining a sufficiently high $Δ$ while keeping a moderate writing current. Micromagnetic simulations were carried out for different pillar thicknesses of fixed lateral size 20 nm. The switching time and the reversal mechanism were analysed as a function of the applied voltage and aspect-ratio (AR) of the storage layer. For AR $$ 1 a non-coherent reversal is observed, characterized by the nucleation of a transverse domain wall at the ferromagnet/insulator interface which then propagates along the vertical axis of the pillar. It was further observed that the inverse of the switching time is linearly dependent on the applied voltage. This study was extended to sub-20 nm width with a value of $Δ$ around 80. It was observed that the voltage necessary to reverse the magnetic layer increases as the lateral size is reduced, accompanied with a transition from macrospin-reversal to a buckling-like reversal at high aspect-ratios.

description: The goal of the research was to present the ability of value creation for owners in agricultural companies and to estimate the relations between the defined value ratio and financial parameters of these entities. To measure the value of agricultural companies for owners a concept of Economic Value Added (EVA) was applied. In 2005-2012 agricultural companies systematically increased the value of invested capital. In the analyzed period agricultural companies were characterized by a low ability of value creation. In the analyzed groups of companies an increase in capital investments was associated with the decrease of rate of return on invested capital measured by EVA.

description: The study on reasons limiting sales of carrot and onion as a fresh vegetables was carried on at 5 retail points in two locations in Skierniewice and in Lublin both in Poland. Five age group customers (total 434) were questioned at groceries shops. As a main factor limiting sales of carrot and onion should be considered the need of peeling and preparing both vegetables before their consumption. It was important for 43,5% purchasers of carrot and for 50,0% purchasers of onion. The other reasons turned out to be fairly less important. As a good solution for sales increase could be the offer of both vegetables ready for immediate consumption for example for carrot as a Baby carrot. The residues and low quality of these vegetables were not important for the questioned consumers. It means that the products in the retail were of good quality.

description: The Internet of Things (IoT) is a paradigm characterized by a network of embedded sensors and services. These sensors are incorporated to collect various information, track physical conditions, e.g., waste bins' status, and exchange data with different centralized platforms. The need for such sensors is increasing; however, proliferation of technologies comes with various challenges. For example, how can IoT and its associated data be used to enhance waste management? In smart cities, an efficient waste management system is crucial. Artificial Intelligence (AI) and IoT-enabled approaches can empower cities to manage the waste collection. This work proposes an intelligent approach to route recommendation in an IoT-enabled waste management system given spatial constraints. It performs a thorough analysis based on AI-based methods and compares their corresponding results. Our solution is based on a multiple-level decision-making process in which bins' status and coordinates are taken into account to address the routing problem. Such AI-based models can help engineers design a sustainable infrastructure system.

Neue Funde aus den präglazialen Terrassen von Süssenborn bei Weimar erwiesen eine Besiedlung auch Mitteldeutschlands, und gleichartige Funde aus den ältesten Donauterrassen bei Wien werden als Hinweis auf eine weitgehend nach Osten in den Kontinent hineinreichende Besiedlung durch den Heidelberger Menschen aufgefaßt. Artefaktfunde aus den Rheinschottern bei Brüggen führen an die plio-pleistozäne Grenze. Im Nachtrag werden Heidelberger Artefakte aus den oberpliozänen Schottern von Sülzfeld in Thüringen angeführt, die den Artefakten von Mauer typologisch sehr nahestehen.

description: The semi-microscopic potential between heavy nuclei is evaluated for various colliding ions in the approach of frozen densities in the framework of the extended Thomas-Fermi approximation with hbar^2 correction terms in the kinetic energy density functional. The proton and neutron densities of each nucleus are obtained in the Hartree-Fock-BCS approximation with SkM* parameter set of the Skyrme force. A simple expression for the nuclear interaction potential between spherical nuclei is presented. It is shown that muon bound with light projectile induces the superheavy elements production in nucleus-nucleus collisions.

Das Problem der Lößbildung und die Lößmollusken
Creators: name: Lozek, Vojen
Publisher: name: Geozon Science Media
Year: 1965

description: Heutzutage wird meist angenommen, daß der Löß nicht nur durch eine bloße Anhäufung von äolischem Staub, sondern auch durch einen spezifischen bodenbildenden Vorgang (sog. Verlössung) entsteht, auf den die charakteristischen Lößmerkmale, namentlich das Gefüge, der Kalkgehalt und die Farbe zurückzuführen sind. Die Verlössungsvorgänge greifen allerdings die gesamte Fläche der betreffenden Gebiete an und gehen auf besondere Umweltbedingungen zurück, die in Europa keine gegenwärtige Analogie haben. Mit dieser Vorstellung stimmt auch die Fauna der Lößmollusken völlig überein, die eine spezifische Zusammensetzung aufweist und mehrere Arten und Rassen umfaßt, die als lößgebunden bezeichnet werden können. Man kann mit Recht von Lößgesellschaften im ökologischen Sinn und demgemäß auch von einer Lößumwelt sprechen, die sowohl durch spezifische Klima-, Sedimentations- und Bodenverhältnisse als auch durch eine charakteristische Fauna und Flora gekennzeichnet ist. Dieser Zeitabschnitt, der als Lößphase zu bezeichnen ist, unterscheidet sich scharf von den übrigen Abschnitten des quartären klimatischen Zyklus. Die Windaufschüttung und Verlössung erfolgen etwa gleichzeitig. Der Wind transportiert ein bereits zum Teil verlößtes Material, das während seiner Ablagerung und auch später durch weitere Verlössung angegriffen wird. Das gilt auch für feinkörnige Ablagerungen nichtäolischer Herkunft, vor allem Hang- und Schwemmbildungen, denen sekundäre Lößmerkmale aufgeprägt werden und die sodann als lößartig zu bezeichnen sind. Sie führen dieselbe Fauna wie der echte Fluglöß. Es sei betont, daß die äolische Staubanhäufung das Sedimentationsbild während der Lößphasen beherrscht, selbst dort, wo sich in anderen Phasen völlig abweichende Vorgänge, z. B. die Grobschuttbildung, geltend machen. Diese Erscheinung sowie die eigenartige Fauna belegen die besonderen Umweltbedingungen der Lößphasen. In höheren bzw. feuchteren Gebieten ist der Löß durch kalkfreie Staublehme ersetzt, die einer anderen Bodenzone der Lößphase entsprechen. Bei der Würdigung der Lößbildungen soll stets der echte Fluglöß von den lößartigen Ablagerungen unterschieden werden, die entweder durch Verlössung nichtäolischer Feinsedimente oder Umlagerung von Fluglöß entstehen. Aus dem Vergleich der malakozoologischen und sedimentologischen Ergebnisse ergibt sich, daß die Lößbildungshypothese von V. A. Obrucev richtig ist.

description: Stochastic power fluctuation in a fiber optic system due to the interplay among dispersion, nonlinearity and partial coherence of the source is investigated. An analytical expression for the power fluctuation of a signal pulse due to its interference with an echo pulse generated due to the nonlinear interaction of signal pulses in a fiber optic system excited by a partially coherent source is obtained. The analytical results show that the mean nonlinear distortion decreases as the coherence time of the source reduces consistent with our numerical simulations.

description: High-multiplicity proton-proton (pp) collisions at the Large Hadron Collider (LHC) energies have created a new domain of research to look for a possible formation of quark-gluon plasma in these events. In this paper, we estimate various thermal properties of the matter formed in pp collisions at the LHC energies, such as mean free path, isobaric expansivity, thermal pressure, and heat capacity using a thermodynamically consistent Tsallis distribution function. Particle species-dependent mean free path and isobaric expansivity are studied as functions of final state charged particle multiplicity for pp collisions at the center-of-mass energy $\sqrt{s}$ = 7 TeV. The effects of degree of non-extensivity, baryochemical potential, and temperature on these thermal properties are studied. The findings are compared with the theoretical expectations.

Ein Vorstoß des Inlandeises in Westgrönland—Dokumentation des vorrückenden Eisrandes bei Søndre Strømfjord
Creators: name: Scholz, Herbert

Year: 1991

description: Nachdem sich das Inlandeis im mittleren Westgrönland — seit einem Höchststand um die Jahrhundertwende — in den letzten Jahrzehnten ständig zurückgezogen hatte, mehren sich neuerdings im mittleren Westgrönland die Hinweise auf einen Vorstoß der Gletscher. Vor allem südlich des Ørkendals, bei Søndre Strømfjord, rückt das Eis seit einigen Jahren kräftig vor und hat ältere, vorgelagerte Wälle größtenteils schon überfahren. Dabei überwiegen heute erosive Prozesse am steilen Eisrand, die vor allem mit dem Abdrängen der peripheren Entwässerungssysteme zusammenhängen. An manchen Stellen schiebt der vorstoßende Gletscher die Vegetationsdecke ab, friert an der Oberfläche der freigelegten Permafrosttafel fest und beansprucht den überfahrenen, dauernd gefrorenen Untergrund so stark, daß noch mehr als 50 m vom Eis entfernt tiefe, wasserwegsame Spalten im Vorland aufreißen. Beobachtungen an einem vorrückenden Gletscher, der in mancher Hinsicht mit den glazialen Eisrändern Mitteleuropas vergleichbar ist, hat für die Interpretation eisrandnah entstandener Sedimente Bedeutung, etwa für die „Vorstoßschotter" im Alpenvorland.

description: For a bilinear map $*:\mathbb R^d\times \mathbb R^d\to \mathbb R^d$ of nonnegative coefficients and a vector $s\in \mathbb R^d$ of positive entries, among an exponentially number of ways combining $n$ instances of $s$ using $n-1$ applications of $*$ for a given $n$, we are interested in the largest entry over all the resulting vectors. An asymptotic behavior is that the $n$-th root of this largest entry converges to a growth rate $λ$ when $n$ tends to infinity. In this paper, we prove the existence of this limit by a special structure called linear pattern. We also pose a question on the possibility of a relation between the structure and whether $λ$ is algebraic.

title: Transforming the self: a study of transition and teacher development
Creators: name: Brown, Tony
Publisher: name: The Open University
Year: 2001

description: Personal and professional development of teachers and trainees is studied through the training period and beyond in England. This is a study of the changing self during transition to teaching, reported through an interpretative narrative of the transitional experience. Three contexts are used: 1. The early development of the author. 2. The author's teaching and research activities with primary trainees in HE. 3. A longitudinal study of secondary trainees. A reflexive approach is used to discuss initial professional development, the growth of personal knowledge and the emergence of a teacher-self. Significant events are identified in the researcher's workplace: teaching episodes, informal meetings and interviews are analysed through a search for noticed themes. A single case study is piloted. Results are used to inform a longitudinal study, with data derived from semi-structured interviews and repertory grids. Data analysis informs the construction of a narrative of transition for each participant using a psychodynamic perspective analyse the data for evidence of conscious influences and unconscious elements. The study draws on Winnicott's theory of transitional space and its application to classrooms. The construct of self is theorised from both intrapersonal and interpersonal perspectives. The emerging teacher-self is evidenced as complex, idiosyncratic and partly influenced by unconscious material from childhood and adolescence. Salient features of participants' transitions are used to extend the theory and elicit an account of each transition. The findings are interpreted from a holistic viewpoint that recognises cognitive, affective and psychic influences on the development of an emergent teacher-self, viewed in terms of agency, intrapersonal and interpersonal dimensions.
Eruptionsgeschichte und Deckschichtenfolge der Wannenköpfe-Vulkangruppe in der Osteifel
Creators: name: Frechen, Manfred
Publisher: name: Geozon Science Media
Year: 1995

description: Die Wannenköpfe gehören zu einer Gruppe von Schlackenkegeln, die unter interstadialen Verhältnissen zu Beginn der vorletzten Kaltzeit im Osteifel-Vulkanfeld ausbrachen. Durch den intensiven Lavaabbau sind derzeit imposante Einblicke in den vulkanologischen Formenschatz und die verschiedenen Eruptionsphasen eines Schlackenkegels gegeben. Die pyroklastische Abfolge beginnt mit phreatomagmatischen Ablagerungen eines initialen Maares. In einer zweiten nichtphreatomagmatischen Phase kommt es zur strombolianischen Förderung von Schlacken und damit zum Aufbau des Schlackenkegels. Im Bereich der Wannen-Vulkangruppe sind Lavaströme sowohl im Westen als auch im Osten ausgeflossen. Aus der Finalphase stammen die Basalt- und Tuffgänge. Mindestens einer dieser Tuffgänge erreichte die Krateroberfläche. Dabei wurde wenig nebengesteinsreiches, feinkörniges Material gefördert. Dieses Material wurde hydrothermal stark zersetzt und liegt als toniges Sediment an der Basis der Kratermulde vor (Profil B). In den Kratermulden und den Depressionen zwischen einzelnen Schlackenkegeln bildeten sieh Sedimentfallen, in denen besonders für den älteren Teil der vorletzten Kaltzeit eine mehr oder weniger lückenlose Sedimentabfolge vorhanden ist. Die Deckschichten beginnen mit Aschen- und Lapilli-Fallablagerungen sowie distalen phreatomagmatischen Ablagerungen benachbarter Eruptionszentren. Die Asche- und Lapillischichten können zum Teil mit den Te-phren anderer Kraterprofile korreliert werden. Zum Hangenden hin sind Horizonte mit Humusanreicherungen zwischengeschaltet, die als Äquivalente von interstadialen, frühsaalezeitlichen Böden interpretiert werden. Die Deckschichtenfolge wird durch einen rotbraunen Bt-Rest einer Parabraunerde, der mit dem Eem-Boden korreliert, untergliedert. Unterweichselzeitliche Humuszonen. humose Fließerden und Lehmbröckelsande lagern diskordant auf dem interglazialen Boden. Die Profile schließen mit einer interstadialen Bodenbildung ab, dem Alleröd-Boden, der sich auf ungegliedertem oberweichselzeitlichem Löß gebildet hat. Darüber lagert der Laacher See-Bims. Aufgrund der tephrochronologischen und lößstratigraphischen Untersuchungen ist eine Kombination der Löß-/Paläobodenabfolge der Wannenköpfe mit denen des Tönchesberges und anderer Schlackenkegelkomplexe möglich. Aus der Kombination der Profile ist eine genaue Einstufung des Ausbruches der Osteifel-Schlackenkegelkomplexe sowie eine Rekonstruktion der paläoklimatischen und paläoökologischen Entwicklung der Osteifel für die letzten 200.000 Jahre ableitbar. Die Wannenköpfe sind unter interstadialen, waldsteppenartigen Klimaverhältnissen ausgebrochen. Nur unwesentlich später sind der Tönchesberg, die Eiterköpfe, sowie der Korretsberg und der Plaidter Hummerich unter ähnlichen klimatischen Bedingungen ausgebrochen. Für den Ausbruch der Hüttenberg-Tephra zu Beginn des vorletzten Interglazials gibt es an den Wannenköpfen keine Belege.

description: Our universe was born about 13.8 billion years ago from an extremely hot and dense singular point, in a process known as the Big Bang. The hot and dense matter which dominated the system within a few microseconds of its birth was in the form of a soup of elementary quarks and gluons, known as the quark-gluon plasma (QGP). Signatures compatible with the formation of the QGP matter have experimentally been observed in heavy-ion (such as Au or Pb) collisions at ultra-relativistic energies. Recently, experimental data of proton-proton (pp) collisions at the CERN Large Hadron Collider (LHC) have also shown signals resembling those of the QGP formation, which made these studies quite stimulating as to how the collision of small systems features in producing the early universe signals. In this article, we report on some of the compelling experimental results and give an account of the present understanding. We review the pp physics program at the LHC and discuss future prospects in the context of exploring the nature of the primordial matter in the early universe.

description: Polarized microwave emission from dust is an important foreground that may contaminate polarized CMB studies unless carefully accounted for. We discuss potential difficulties associated with this foreground, namely, the existence of different grain populations with very different emission/polarization properties and variations of the polarization yield with grain temperature. In particular, we discuss observational evidence in favor of rotational emission from tiny PAH particles with dipole moments, i.e. ``spinning dust'', and also consider magneto-dipole emission from strongly magnetized grains. We argue that in terms of polarization, the magneto-dipole emission may dominate even if its contribution to total emissivity is subdominant. Addressing polarized emission at frequencies larger than approsimately 100 GHz, we discuss the complications arising from the existence of dust components with different temperatures and possibly different alignment properties.

description: Classical transition state theory (TST) is the cornerstone of reaction rate theory. It postulates a partition of phase space into reactant and product regions, which are separated by a dividing surface that reactive trajectories must cross. In order not to overestimate the reaction rate, the dynamics must be free of recrossings of the dividing surface. This no-recrossing rule is difficult (and sometimes impossible) to enforce, however, when a chemical reaction takes place in a fluctuating environment such as a liquid. High-accuracy approximations to the rate are well known when the solvent forces are treated using stochastic representations, though again, exact no-recrossing surfaces have not been available. To generalize the exact limit of TST to reactive systems driven by noise, we introduce a time-dependent dividing surface that is stochastically moving in phase space such that it is crossed once and only once by each transition path.

description: The analysis of consumers' personal information (PI) is a significant source to learn about consumers. In online settings, many consumers disclose PI abundantly -- this is particularly true for information provided on social network services. Still, people manage the privacy level they want to maintain by disclosing by disclosing PI accordingly. In addition, studies have shown that consumers' online self-disclosure (OSD) differs across cultures. Therefore, intelligent systems should consider cultural issues when collecting, processing, storing or protecting data from consumers. However, existing studies typically rely on a comparison of two cultures, providing valuable insights but not drawing a comprehensive picture. We introduce an open research model for cultural OSD research, based on the privacy calculus theory. Our open research model incorporates six cultural dimensions, six predictors, and 24 structured propositions. It represents a comprehensive approach that provides a basis to explain possible cultural OSD phenomena in a systematic way.

Die flußgeschichtliche Entwicklung der Niederrheinischen Bucht im Jungtertiär und Altquartär.
Creators: name: Boenigk, Wolfgang
Publisher: name: Geozon Science Media
Year: 1978

description: Die sedimentologische und petrographische Bearbeitung der Braunkohlen-Deckschichten zeigt für die Niederrheinische Bucht im Miozän und Pliozän ein küstennahes Ablagerungsmilieu. Relativ kleinräumige Faziesverschiebungen und Schwankungen des Klimas zwischen feuchten und trockeneren Phasen verursachen die wechselnden Sedimentationstypen. Größere Relativbewegungen von Meeresspiegel zu Niederrheinischer Bucht sind nur über einige Erosionsdiskordanzen zu fassen. Im Pleistozän herrscht ausschließlich fluviatile Sedimentation, unterbrochen durch markante Erosionsphasen. Der Wechsel zwischen Erosion und Ablagerung und die Änderung in der petrographischen Zusammensetzung der Sedimente wird durch das Zusammenwirken von tektonischen Bewegungen und klimatischen Rhythmen des Altquartärs geprägt.

description: In den letzten Jahren konnte im englischsprachigen, wie auch im deutschsprachigen Raum ein Anstieg von tiergestützten Interventionen wahrgenommen werden. Der Einsatz von Tieren zur Verbesserung von Gesundheit, Wohlbefinden und Leistung weckt zunehmend das Interesse der Gesellschaft, wie auch der Forschung. Diese Masterthese befasst sich mit der Frage, inwiefern Interventionen mit Hunden die sozial-emotionalen Kompetenzen von Schulkindern fördern können. Ein besonderes Augenmerk wird dabei auf Kinder mit sonderpädagogischem Förderbedarf in diesem Bereich gelegt. Neben der ausgewählten Fachliteratur werden zur Beantwortung der Fragestellung acht aktuelle, relevante Studien vorgestellt und anhand einer qualitativen Inhaltsanalyse ausgewertet. Diese ergibt, dass vor allem Teilkompetenzen wie die Empathie und die Emotionsregulation, welche auch Verhaltenskontrolle, Aggressionsreduktion und Stressmanagement beinhaltet, durch hundegestütze Interventionen bei Kindern mit und ohne Emotions- und Verhaltensstörungen verbessert werden können. Diese Arbeit schafft eine Verbindung zwischen gängiger Fachliteratur und wissenschaftlicher Forschung und impliziert Konsequenzen für die Praxis der schulischen Heilpädagogik, sowie für zukünftige Studien.

description: Gaits and transitions are key components in legged locomotion. For legged robots, describing and reproducing gaits as well as transitions remain longstanding challenges. Reinforcement learning has become a powerful tool to formulate controllers for legged robots. Learning multiple gaits and transitions, nevertheless, is related to the multi-task learning problems. In this work, we present a novel framework for training a simple control policy for a quadruped robot to locomote in various gaits. Four independent phases are used as the interface between the gait generator and the control policy, which characterizes the movement of four feet. Guided by the phases, the quadruped robot is able to locomote according to the generated gaits, such as walk, trot, pacing and bounding, and to make transitions among those gaits. More general phases can be used to generate complex gaits, such as mixed rhythmic dancing. With the control policy, the Black Panther robot, a medium-dog-sized quadruped robot, can perform all learned motor skills while following the velocity commands smoothly and robustly in natural environment.

description: Nach einem Überblick über den gegenwärtigen Stand der pollenanalytischen Erforschung des Letzten- oder Eem-Interglazials in Nordwestdeutschland, werden die besonderen Merkmale in der Vegetationsentwicklung dieses Interglazials beschrieben und die Unterschiede gegenüber älteren und jüngeren Ablagerungen dargestellt. Die Kieselgurlager von Munster und Ohe, die außerhalb der morphologischen Grenze des Warthe-Vorstoßes liegen, zeigen einen anderen Ablauf der Waldgeschichte und können damit nicht dem Eem-Interglazial angehören. Auf Grund der Lagerungsverhältnisse, die eingehend besprochen werden, sind die Kieselgur-Vorkommen von Munster und Ohe in ein Interglazial zwischen dem äußersten Vorstoß der Saale-Vereisung (Drenthien) und der Warthe-Vereisung zu stellen. Das Interglazial muß von kürzerer Dauer gewesen sein, so daß ein extrem hoher Meeresstand nicht erreicht wurde. Drenthe- und Warthe-Vereisung sind zwei Unterabschnitte der Saale-Eiszeit. Für das kurze Interglazial zwischen dem Drenthien und der Warthe-Vereisung wird die Bezeichnung Ohe -Interglazial vorgeschlagen, da an der Kieselgur von Neu-Ohe die besondere Vegetationsentwicklung zuerst festgestellt wurde.

description: The anomalous magnetic moment of the negative muon has been measured to a precision of 0.7 parts per million (ppm) at the Brookhaven Alternating Gradient Synchrotron. This result is based on data collected in 2001, and is over an order of magnitude more precise than the previous measurement of the negative muon. The result a_mu= 11 659 214(8)(3) \times 10^{-10} (0.7 ppm), where the first uncertainty is statistical and the second is sytematic, is consistend with previous measurements of the anomaly for the positive and negative muon. The average for the muon anomaly a_{mu}(exp) = 11 659 208(6) \times 10^{-10} (0.5ppm).

Sparse SVM for Sufficient Data Reduction

description: Kernel-based methods for support vector machines (SVM) have shown highly advantageous performance in various applications. However, they may incur prohibitive computational costs for large-scale sample datasets. Therefore, data reduction (reducing the number of support vectors) appears to be necessary, which gives rise to the topic of the sparse SVM. Motivated by this problem, the sparsity constrained kernel SVM optimization has been considered in this paper in order to control the number of support vectors. Based on the established optimality conditions associated with the stationary equations, a Newton-type method is developed to handle the sparsity constrained optimization. This method is found to enjoy the one-step convergence property if the starting point is chosen to be close to a local region of a stationary point, thereby leading to a super-high computational speed. Numerical comparisons with several powerful solvers demonstrate that the proposed method performs exceptionally well, particularly for large-scale datasets in terms of a much lower number of support vectors and shorter computational time.

description: In this study, a heuristic dynamic programming controller is proposed to control a boost converter. Conventional controllers such as proportional integral-derivative (PID) or proportional integral (PI) are designed based on the linearized small-signal model near the operating point. Therefore, the performance of the controller during the start-up, the load change, or the input voltage variation is not optimal since the system model changes by varying the operating point. The heuristic dynamic programming controller optimally controls the boost converter by following the approximate dynamic programming. The advantage of the HDP is that the neural network based characteristic of the proposed controller enables boost converters to easily cope with large disturbances. An HDP with a well trained critic and action networks can perform as an optimal controller for the boost converter. To compare the effectiveness of the traditional PI-based and the HDP boost converter, the simulation results are provided.
