description: There is renewed interest in rare-earth elements and gadolinium in particular for a range of studies in coupling physics and applications. However, it is still apparent that synthesis impacts understanding of the intrinsic magnetic properties of thin gadolinium films, particularly for thicknesses of topicality. We report studies on 50nm thick nanogranular polycrystalline gadolinium thin films on SiO2 wafers that demonstrate single-crystal like behavior. The maximum in-plane saturation magnetization at 4K was found to be 4πMS4K = (2.61{\pm}0.26)T with a coercivity of HC4K = (160{\pm}5)Oe. A maximum Curie point of TC = (293{\pm}2)K was measured via zero-field-cooled - field- cooled magnetization measurements in close agreement with values reported in bulk single crystals. Our measurements revealed magnetic transitions at T1 = (12{\pm}2)K (as deposited samples) and T2 = (22{\pm}2)K (depositions on heated substrates) possibly arising from the interaction of paramagnetic fcc grains with their ferromagnetic hcp counterparts.

description: Given a closed hyperbolic 3-manifold M with a quasigeodesic flow we construct a π_1-equivariant sphere-filling curve in the boundary of hyperbolic space. Specifically, we show that any complete transversal P to the lifted flow on H^3 has a natural compactification as a closed disc that inherits a π_1 action. The embedding of P in H^3 extends continuously to the compactification and the restriction to the boundary is a surjective π_1-equivariant map from S^1 to S^2_\infty. This generalizes the result of Cannon and Thurston for fibered hyperbolic 3-manifolds.

description: Humans do not always make rational choices, a fact that experimental economics is putting on solid grounds. The social context plays an important role in determining our actions, and often we imitate friends or acquaintances without any strategic consideration. We explore here the interplay between strategic and social imitative behaviors in a coordination problem on a social network. We observe that for interactions in 1D and 2D lattices any amount of social imitation prevents the freezing of the network in domains with different conventions, thus leading to global consensus. For interactions in complex networks, the interplay of social and strategic imitation also drives the system towards global consensus while neither dynamics alone does. We find an optimum value for the combination of imitative behaviors to reach consensus in a minimum time, and two different dynamical regimes to approach it: exponential when social imitation predominates, and power-law when strategic considerations dominate.

description: Nanostructured polymer-metal oxide composites are a current research area of great importance due to its highlight applications in sensors, optics, catalysts and drug delivery. Particularly the use of thermoresponsive polymers gives more flexibilities and possibilities in the design and construction of polymer templates. In the present investigation, the structure and magnetic properties of hybrid metal oxide/DBC films composed of two kinds of polystyrene-block-poly (N-isopropylacrylamide)(PS-b-PNIPAM) diblock copolymers (DBCs) with PS and PNIPAM as the major polymer domains respectively, and iron oxide were investigated. The thermoresponsive PNIPAM has a lower critical solution temperature (LCST) in aqueous solution at 32°C, which enables the controllable volume ratio of PS and PNIPAM in the structure of PS-b-PNIPAM diblock copolymers (DBCs). Thus, a temperature and humidity controlling cell was designed and built for precisely tuning the block structure of PS-b-PNIPAM DBCs, which was investigated by in-situ small-angle X-ray scattering (SAXS) and grazing-incidence small-angle X-ray scattering (GISAXS) measurements. The superparamagnetic behavior of the heat-treated hybrid iron oxide/PS-b-PNIPAM DBC films was investigated using a superconducting quantum interference device (SQUID) magnetometer.

description: Let $\mathcal F$ be a holomorphic one-dimensional foliation on $\mathbb{P}^n$ such that the components of its singular locus $Σ$ are curves $C_i$ and points $p_j$. We determine the number of $p_j$, counted with multiplicities, in terms of invariants of $\mathcal F$ and $C_i$, assuming that $\mathcal F$ is special along the $C_i$. Allowing just one nonzero dimensional component on $Σ$, we also prove results on when the foliation happens to be determined by its singular locus.

description: We study the phenomenology of the Peccei-Quinn invariant extension of the next-to-minimal supersymmetric standard model (NMSSM) in view of the recent discovery of a 125 GeV Higgs boson. The minimal model having no quadratic and cubic terms of the NMSSM singlet field predicts a light singlino-like lightest supersymmetric particle (LSP). The model is strongly constrained by the Higgs invisible decay and the dark matter characteristic of the LSP, while some constraints can be relaxed by assuming that the saxion, the CP-even companion of the axion in the Peccei-Quinn sector, causes a late-time entropy production diluting the thermal LSP density. The collider signal of the model contains multi-jet and $h/W/Z$ plus missing energy, which can be discovered in the early stage of the 14 TeV LHC running.

Search for light scalar top quark pair production in final states with two leptons with the ATLAS detector in sqrt(s) = 7 TeV proton-proton collisions

description: A search is presented for the pair production of light scalar top quarks in sqrt(s) = 7 TeV proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider. This analysis uses the full data sample collected during 2011 that corresponds to a total integrated luminosity of 4.7 fb-1. Light scalar top quarks are searched for in events with two opposite-sign leptons (e, mu), large missing transverse momentum and at least one jet in the final state. No excess over Standard Model expectations is found, and the results are interpreted under the assumption that the light scalar top decays to a b-quark in addition to an on-shell chargino whose decay occurs through a virtual W boson. If the chargino mass is 106 GeV, light scalar top quark masses up to 130 GeV are excluded for neutralino masses below 70 GeV.

description: Energy is the primary issue in the development of the world economy. Currently, many countries regard the development of new energy as a response to the financial crisis and an important measure to accelerate the economic recovery. As an inexhaustible clean natural energy, solar energy is one of the most promising energy. At present, the most extensive research and application of solar cells is silicon solar cells. Due to high raw material costs, complex production process and limited improved efficiency, silicon cells’ civilian subjected to technical restriction.Compared to silicon solar cells, dye-sensitized solar cells have a relatively inexpensive price and potentially high photoelectric conversion efficiency, what’s more, can be made into flexible products and simply fabricated.Therefore,it’s most likely to replace the traditional silicon solar cells and become the dominant of the photovoltaic industry in the near future.

description: Very high precision seismic space missions such as CoRoT and Kepler provide the means of testing the modeling of transport processes in stellar interiors. For some stars, such as solar-like and red giant stars, a rotational splitting is measured. However, in order to fully exploit these splittings and constrain the rotation profile, one needs to be able to calculate them accurately. For some other stars, such as $δ$ Scuti and Be stars, for instance, the observed pulsation spectra are modified by rotation to such an extent that a perturbative treatment of the effects of rotation is no longer valid. We present here a new two-dimensional non-perturbative code, called ACOR (\textit{Adiabatic Code of Oscillation including Rotation}) which allows us to compute adiabatic non-radial pulsations of rotating stars, without making any assumptions on the sphericity of the star, the fluid properties (i.e. baroclinicity) or the rotation profile. The 2D non-perturbative calculations fully take into account the centrifugal distortion of the star and include the full influence of the Coriolis acceleration. The numerical method is based on a spectral approach for the angular part of the modes, and a fourth-order finite differences approach for the radial part. We test and evaluate the accuracy of the calculations by comparing them with those coming from TOP (\textit{Two-dimensional Oscillation Program}) for the same polytropic models. We illustrate the effects of rapid rotation on stellar pulsations through the phenomenon of avoided crossings. As shown by the comparison with TOP for simple models, the code is stable, and gives accurate results up to near-critical rotation rates.

description: Ethernet ist eine ausgereifte Kommunikationstechnologie mit vielen Vorteilen für Sensornetzwerke und einer Vielzahl anderer Einsatzbereiche. Anwendungen interagieren mit einer sogenannten Media-Access-Control-(MAC)-Unterschicht, um Pakete vom Netzwerk zu empfangen und zu versenden. Diese Arbeit stellt den Entwurf, die Implementierung und den Test einer in VHDL umgesetzten MAC-Schicht für Ethernet auf FPGAs vor. Die Kommunikation mit einem integrierten Schaltkreis, der die Bitübertragungsschicht von Ethernet umsetzt, erfolgt über das standardisierte Media-Independent Interface (MII) in den Varianten MII und GMII. Dabei werden Verbindungsgeschwindigkeiten von 10, 100 und 1000 Mb/s im Vollduplex-Modus unterstützt. Im Gegensatz zu bisherigen Lösungen liegt der Schwerpunkt des Entwurfs auf Einfachheit sowohl in der externen Benutzung als auch den internen Abläufen. Benutzern kommt die unkomplizierte FIFO-Schnittstelle zugute, mit der sie gleichzeitig bei nahezu voller Gigabit-Ethernet-Geschwindigkeit senden und empfangen können. Die MAC-Schicht wurde für ein GigaBee-Mikromodul der Trenz Electronic GmbH mit einem FPGA der Spartan-6-Familie von Xilinx entworfen und ebenfalls damit geprüft.
description: Ethernet is a mature communication technology with a sizable number of advantages for sensor networks and many other use cases. Applications interact with a media access control (MAC) sublayer to get packets from and to the network. This thesis presents the design, implementation, and test of an Ethernet MAC targeted at FPGAs in VHDL. It supports full-duplex interfacing with an Ethernet physical layer integrated circuit via the standard media-independent interface (MII) variants MII and GMII at link speeds of 10, 100, and 1000 Mb/s. In contrast to prior solutions, it is devised primarily with simplicity in mind, both in external usage and in internal operation. Users benefit from the straightforward FIFO interface offered while nevertheless being able to send and receive at almost full Gigabit Ethernet speed. The solution is designed for and verified on a Trenz Electronic GmbH GigaBee micromodule with a Xilinx Spartan-6 family FPGA.

description: A detailed 3D distribution of interstellar matter in the solar neighborhood is increasingly necessary. As part of a 3D mapping program, we aim at assigning a precise distance to the high-latitude HI gas in particular the northern part (b \geq 55^{circ}) of the shell associated with the conspicuous radio continuum Loop I. This shell is thought to be the expanding boundary of an interstellar bubble inflated and recently reheated by the strong stellar winds of the nearby Scorpius-Centaurus OB. We recorded high-resolution spectra of 30 A-type target stars located at various distances in the direction of the northern part of Loop I. Interstellar NaI 5889-5895 and CaII K-H 3934-3968 Å are modeled and compared with the HI emission spectra from the LAB Survey. About two-thirds of our stellar spectra possess narrow interstellar lines. Narrow lines are located at the velocity of the main, low-velocity Loop 1 HI shell ([-6,+1] km/s in the LSR). Using Hipparcos distances to the target stars, we show that the closest boundary of the b geq+70^{\circ} part of this low-velocity Loop I arch is located at of 98 \pm 6 pc. The corresponding interval for the lower-latitude part (55^{\circ} \leq b \leq 70^{\circ}) is 95-157 pc. However, since the two structures are apparently connected, the lower limit is more likely. At variance with this shell, the second HI structure, which is characterized by LSR Doppler velocities centered at -30 km/s, is NOT detected in any of the optical spectra. It is located beyond 200 parsecs or totally depleted in NaI and CaII. We discuss these results in the light of spherical expanding shells and show that they are difficult to reconcile with simple geometries and a nearby shell center close to the Plane. Instead, this high-latitude gas seems to extend the inclined local chimney wall to high distances from the Plane.

description: Viele aktuelle Field Programmable Gate Arrays (FPGAs) unterstützen die Technik der partiellen Rekonfiguration (PR), durch die dynamisch zur Laufzeit ein Hardware-Design auch nur teilweise ausgetauscht werden kann. Die vorliegende Arbeit integriert PR-Funktionalität in die an der Technischen Universität Ilmenau für harte Echtzeitaufgaben mit hochpräzisen Fließkommaberechnungen entwickelte VHDL Integrated Softcore Architecture for Reconfigurable Devices (ViSARD). Zu diesem Zweck wird die arithmetisch-logische Einheit angepasst, um das Auswechseln von Fließkomma-Ausführungseinheiten zu ermöglichen. Ziele der Entwicklung des PR-Systems sind hohe Geschwindigkeit, niedrige Latenz, niedrige Ressourcenkosten und harte Echtzeitfähigkeit. Erreicht werden diese durch die Umsetzung einer eigenen Steuereinheit (partial reconfiguration controller), die partielle Bitströme aus externem RAM über einen standardmäßigen AXI-Bus lädt sowie die entsprechende Erweiterung der ViSARD. In einem Testdesign, das zwischen drei verschiedenen Konfigurationen mit je zwischen einer und drei Ausführungseinheiten wechselt, hat das entwickelte PR-System den maximal spezifierten Bitstromdurchsatz auf dem Ziel-FPGA erreicht und den Verbrauch an Lookup-Tabellen um etwa 40 % verringert.
description: Many modern field-programmable gate arrays (FPGAs) support partial reconfiguration, which allows to dynamically replace only a part of a design at run time. In this thesis, partial reconfiguration capability is integrated with the VHDL Integrated Softcore Architecture for Reconfigurable Devices (ViSARD) developed at Technische Universität Ilmenau and conceived for hard real-time tasks requiring floating-point calculations with high precision. Specifically, its arithmetic logic unit is modified to allow exchanging floating-point arithmetic execution units. Design goals of the partial reconfiguration system are high speed, low latency, low resource overhead, and hard real-time capability. They are reached by implementing a custom partial reconfiguration controller loading partial bitstreams from external RAM over a standard AXI bus and extending the ViSARD appropriately. In a test design that switched between 3 different configurations each containing between 1 and 3 execution units, the proposed partial reconfiguration system achieved the maximum specified bitstream throughput on the target FPGA and allowed for roughly 40 % reduced look-up table usage.

 Remarks. Anacroneuria amargosa was collected at Serra dos Pireneus and is a new record for Goiás state. This species was originally described in Mid-South Mesoregion of the Bahia state, and the present study expands the distribution to Central Brazil. The collected specimen is similar to the holotype described by Righi-Cavallaro & Froehlich in Righi-Cavallaro et al. (2013) and agrees in color, size, and penial armature shape. As commented by Righi-Cavallaro et al. (2013), the penial armature resembles Anacroneuria boraceiensis Froehlich, 2004.

Exotic spin, charge and pairing correlations of the two-dimensional doped Hubbard model: a symmetry entangled mean-field approach

description: Intertwining of spin, charge and pairing correlations in the repulsive two-dimensional Hubbard model is shown through unrestricted variational calculations, with projected wavefunctions free of symmetry breaking. A crossover from incommensurate antiferromagnetism to stripe order naturally emerges in the hole-doped region when increasing the on-site coupling. Although effective pairing interactions are identified, they are strongly fragmented in several modes including d-wave pairing and more exotic channels related to an underlying stripe. We demonstrate that the entanglement of a mean-field wavefunction by symmetry restoration can largely account for interaction effects.

description: We present a clustering analysis of near ultraviolet (NUV) - optical color selected luminosity bin samples of green valley galaxies. These galaxy samples are constructed by matching the Sloan Digital Sky Survey Data Release 7 with the latest Galaxy Evolution Explorer source catalog which provides NUV photometry. We present cross-correlation function measurements and determine the halo occupation distribution of these transitional galaxies using a new multiple tracer analysis technique. We extend the halo-occupation formalism to model the cross-correlation function between a galaxy sample of interest and multiple tracer populations simultaneously. This method can be applied to commonly used luminosity threshold samples as well as to color and luminosity bin selected galaxy samples, and improves the accuracy of clustering analyses for sparse galaxy populations. We confirm the previously observed trend that red galaxies reside in more massive halos and are more likely to be satellite galaxies than average galaxies of similar luminosity. While the change in central galaxy host mass as a function of color is only weakly constrained, the satellite fraction and characteristic halo masses of green satellite galaxies are found to be intermediate between those of blue and red satellite galaxies.

description: The CORNISH project is the highest resolution radio continuum survey of the Galactic plane to date. It is the 5 GHz radio continuum part of a series of multi-wavelength surveys that focus on the northern GLIMPSE region (10 deg < l < 65 deg), observed by the Spitzer satellite in the mid-infrared. Observations with the Very Large Array in B and BnA configurations have yielded a 1.5" resolution Stokes I map with a root-mean-squared noise level better than 0.4 mJy/beam. Here we describe the data-processing methods and data characteristics, and present a new, uniform catalogue of compact radio-emission. This includes an implementation of automatic deconvolution that provides much more reliable imaging than standard CLEANing. A rigorous investigation of the noise characteristics and reliability of source detection has been carried out. We show that the survey is optimised to detect emission on size scales up to 14" and for unresolved sources the catalogue is more than 90 percent complete at a flux density of 3.9 mJy. We have detected 3,062 sources above a 7-sigma detection limit and present their ensemble properties. The catalogue is highly reliable away from regions containing poorly-sampled extended emission, which comprise less than two percent of the survey area. Imaging problems have been mitigated by down-weighting the shortest spacings and potential artefacts flagged via a rigorous manual inspection with reference to the Spitzer infrared data. We present images of the most common source types found: regions, planetary nebulae and radio-galaxies. The CORNISH data and catalogue are available online at http://cornish.leeds.ac.uk

 Remarks. Anacroneuria brandaoi was first described at the Serra da Mesa, in the north of Goiás state (Bispo & Froehlich 2004). In this work, we recorded the species in the Chapada dos Veadeiros and Serra dos Pireneus, Goiás state. The penial armature of A. brandaoi differs from that of the holotype of A. debilis (Zwick 1972). However, recent studies of different populations of A. debilis (Baldin et al. 2013; Bispo et al. 2014; Novaes & Bispo 2014a) revealed high variability in the penial armature, which could overlap with that of A. brandoi. Herein, we observed that the penial armature of A. brandaoi has a more rounded keel and that the apex tapers less abruptly (Fig. 3) than that of A. debilis from the same location.

description: The problem of a spatially correlated noise affecting a complex system is studied in this paper. We present a comprehensive analysis of a 2D model polymer chain, driven by the spatially correlated Gaussian noise, for which we have varied the amplitude and the correlation length. The chain model is based on a bead-spring approach, enriched with a global Lennard-Jones potential and angular interactions. We show that spatial correlations in the noise inhibit the chain geometry dynamics, enhancing the preservation of the polymer shape. This is supported by the analysis of correlation functions of both the module length and angles between neighboring modules, which have been measured for the noise amplitude ranging over 3 orders of magnitude. Moreover, we have observed the correlation length dependent beads motion synchronization, and the spontaneous polymer unfolding, resulting from an interplay between chain potentials and the spatially structured noise.
