The oldest representative of a modern deep-sea ophiacanthid brittle-star clade from Jurassic shallow-water coral reef sediments
2012-01-01

Ophiurites crinitus is a fossil brittle-star species which passed largely unnoticed since its original description. In this paper, we redescribe the type material of O. crinitus with the aim to put it into the context of modern ophiuroid systematics, and propose the new genus name Ophiosternle to replace the invalid Ophiurites. The re-assessed species is shown to be a member of the extant deep-sea family Ophiacanthidae, articulated fossils of which are extremely rare. It presents greatest affinities with members of the Ophioplinthaca-Ophiocamax-Ophiomitra clade, of which it most probably represents the oldest known fossil species. The depositional environment of the strata, which yielded the described specimens is interpreted as shallow, storm-influenced marine setting in the immediate vicinity of coral reefs. This contrasts with the distribution pattern of extant species of the Ophioplinthaca-Ophiocamax-Ophiomitra clade, which almost exclusively occur at depths exceeding the shelf break.
Treebanks: Linking Linguistic Theory to Computational Linguistics
2012-01-01

Treebanks are language resources that provide annotations at various levels of linguistic structure starting from the word level. They typically provide syntactic constituent or dependency structures for sentences, but increasingly extend to annotation beyond syntactic structure, including semantic, pragmatic and rhetorical annotation, or go beyond a single language, as in parallel treebanks.&#x0D; Experience in building treebanks has shown that there is a close relation between formal linguistic theory and the design and practice of annotation. With increasing complexity of annotations, the design of annotation schemes becomes more and more theory-dependent. At the same time, linguistically motivated treebank annotations have become crucially important for the development of data-driven approaches to natural language processing and for linguistic research in general.&#x0D; Treebanks therefore constitute an important link between linguistic theory and computational linguistics.&#x0D; The International Workshop on Treebanks and Linguistic Theories provides a forum for researchers working on treebanks from both perspectives. The present volume presents the contents of the 10th edition of this workshop series, held in 2012 at the University of Heidelberg.
Autonomous Aerial Sensors for Wind Power Meteorology
2012-01-01

This paper describes a new approach for measurements in wind power meteorology using small unmanned flying platforms. Large-scale wind farms, especially offshore, need an optimisation between installed wind power density and the losses in the wind farm due to wake effects between the turbines. Good measurements of the wake and wake structure are not easy to come by, especially offshore. Very few measurement masts exist to verify our knowledge of atmospheric physics, and most of them are situated in quite homogeneous and gentle terrain. Here, automated Unmanned Aerial Vehicles (UAVs) could be used as either an extension of current masts or to build a network of very high 'masts' in a region of complex terrain or coastal flow conditions. In order to test the potential and limits of UAVs for wind power meteorology, this project assembles four different UAVs from four participating groups. Risø has built a lighter-than-air kite with a long tether and nano-synchronised sensors, Bergen University flies the SUMO, a pusher airplane of 580g total weight equipped with a 100Hz Pitot tube, Tübingen University in conjunction with the TU Braunschweig flies the Carolo, a 2m wide two prop model with a 5-hole pitot tube on the nose, and Aalborg University will use a helicopter with a sonic anemometer as a slung load. It was planned to fly all those platforms during one week at the Danish national test station for large wind turbines at Høvsøre. One of the large lessons learnt was that permitting is a major concern - both the campaign at Høvsøre and the alternate location at Risø had to be cancelled for different reasons, both related to flying permits. There was one week of flying though at the Nøjsomheds Odde wind farm in Lolland, where we could compare the SUMO and balloon with a Lidar and data from the wind farm. The other platforms performed their tests separately. Lastly, the lessons learnt were used to do a detailed planning for a possible offshore campaign.
Strategic Delegation in Price Competition
2012-01-01

We study price competition in heterogeneous markets where price decisions are delegated to agents. Principals implement a revenue sharing scheme to which agents react by commonly charging a sales price. The results of our model exemplify the importance of both intra- and interfirm interactions of principals and agents in competition. We show that price delegation can increase or decrease the firms’ surplus depending on the heterogeneity of the market and the number of agents employed by the firms.
Determination of Beta-Cell Function: Ion Channel Function in Beta Cells
2012-01-01

For the regulation of beta-cell function ion channels are of outstanding importance. Beta cells are specialized to convert changes in blood glucose concentration to an adequate secretory response. To achieve this, nutrient-induced alterations of electrical activity are directly coupled to changes in insulin release. Consequently, determination and analysis of ion channel activity are important tools for the characterization of beta-cell (patho)physiology and for the investigation of drugs that influence insulin release. With implementation of the patch-clamp technique it has become possible to analyze ion currents in beta cells under various conditions (e.g., in intact cells or independent of cell metabolism, as whole-cell currents or on a single channel level). In addition, this method enables to combine ion current recordings with determination of membrane potential and exocytosis. This chapter introduces the basic principles of different patch-clamp configurations and focuses on experimental protocols for ion channel recordings in beta cells.
Self-Monitoring and Linguistic Adaptation
2012-01-01

This article explores the role of self-monitoring in the adaptation to different linguistic environments (dialects and foreign languages). An internet study (N = 505) found the motivation and ability of speakers of local German dialects to switch to the German high language (as measured by a specifically developed scale) to be moderately related (r = .24) to their self-monitoring scores. Further analyses found this relationship to be stronger for people with stronger dialects. Also, in a survey of German first-year students (N = 88) at a Dutch university, self-monitoring was strongly related (r = .43) to a scale measuring various aspects of adaptation to the Dutch language; high self-monitors also reported less social and study-related problems due to language. We conclude from these results that self-monitoring is an important determinant of oral linguistic adaptation. Put differently, our findings extend the reach of the self-monitoring construct to the domain of language.
Atopaxar
2012-01-01

Summary Atopaxar, also known as E 5555 is a novel reversible protease-activated receptor-1 (PAR-1) thrombin receptor antagonist. To date, Atopaxar has been investigated in phase II trials with focus on safety and tolerability in patients with acute coronary syndromes or stable coronary artery disease on top of standard antiplatelet therapy. Atopaxar was generally well tolerated, however a rise in liver enzymes and prolongation of the QTcF interval were observed. The data suggest, that atopaxar administration may promote some minor bleeding complications, but does not seem to significantly increase the risk of major bleeding. Although not powered for efficacy, the currently available data suggest potential benefits in patients at high risk for recurrent ischemic events on top of standard antiplatelet therapy. In conclusion, more studies (e.g. phase III) are needed to evaluate efficacy and safety of atopaxar.
Asymptomatic melanoma of the superior cavo-atrial junction: The challenge of imaging
2012-01-01

METASTATIC LESIONS IN THE SUPERIOR VENA CAVA AND THE RIGHT ATRIUM ARE DIFFICULT TO DIAGNOSE: in computed tomography (CT), they are easily misinterpreted as artifacts, and the same region may be difficult to access using echocardiography. We present a case of asymptomatic metastasis of a malignant melanoma which was overlooked initially due to deficiencies in imaging. Using 18F-fluorodeoxyglucose positron emission tomography-CT, the metastasis was clearly identified and finally treated successfully. We discuss the diagnostic value of the various imaging modalities for intracardiac masses.
1.3.5 Conduction Mechanism in Undoped and Antimony Doped SnO2 Based FSP Gas Sensors
2012-01-01

The conduction mechanism in highly porous thick film SnO 2 sensing layers, obtained by a direct deposition technique using FSP (Flame Spray Pyrolysis), and the influence of different antimony (Sb) doping levels on the electrical properties of the host material is investigated by simultaneous DC electrical resistance and work function changes measurements in various ambient atmospheres.The situation in the case of the undoped FSP-sensors is very similar to the results obtained on polycrystalline thick film layers: we found a seamless transfer of the conduction mechanism from a depletion layer controlled one to the flat band situation and to an accumulation layer controlled one.The switch between these two models directly occurs in the absence of ambient oxygen, indicating that the depletion region is only determined by its adsorption.The degeneration of the semiconductor, in the case of the accumulation layer controlled conduction mechanism, is not observed.The addition of Sb influences the conduction mechanism dramatically due to its effect on the bulk concentration of free charge carriers.In contrast to the undoped FSP-SnO 2 sensor there is a direct switch from a conduction mechanism controlled by the depletion layer to the degenerate semiconductor situation that indicates a deep crossing of the Fermi level into the conduction band; moreover an initial upward band bending is observed.
Religious Education, Identity and Faith in (Post-)Modernity: More than a Biographical Approach?
2012-01-01

I rarely think about 'my approach' to religious education. Yet sometimes others tell me that my name stands for a biographical approach. Are they right? My more than 30 years of work in this academic area after graduation should have produced enough evidence for whatever model I might actually have followed. This is why I start this essay with biographical reflections on my work, trying, as it were, to look over my own shoulder.
Double Bolus Application in TWIST-MR-Angiography of the Cervical Arteries
2012-01-01

Purpose . The aim of the present work was to test the feasibility of the time-resolved MR-angiography (TWIST-MRA) of cervical arteries using double bolus injection. Material and Methods . TWIST-MRA with a temporal resolution of 8.4 seconds for each frame and a spatial resolution with a voxel size of was performed in 24 patients. A biphasic bolus injection protocol was used with the second injection being started 21 seconds after the first contrast dye bolus. Diagnostic image quality was rated according to a 4-point scale. Results . In 12 patients (50%) no clear separation between the cervical venous and arterial vessels was evident after the first bolus injection. Using TWIST-MRA data acquired after the second bolus a sufficient diagnostic image quality (rating , mean 3.5) could be obtained in 22 of 24 patients (92%). Discussion . The double bolus injection protocol using TWIST-MRA allows for very good separation of the cervical arteries.
Vor wem soll die Auskundschaftung Jerichos geheim gehalten werden? Eine Frage zu Josua 2:1
2012-01-01

Abstract The present paper poses an often overlooked question and weighs possible answers: Does the word חרש in Josh 2:1 qualify the mission of the spies sent to Jericho, or is it meant to inform the reader that Joshua kept that mission a secret from the Israelites?
The Complexity of Intersecting Finite Automata Having Few Final States.
2012-01-01

Abstract. The problem of determining whether several finite automata accept a common word is closely related to the well-studied membership problem in transformation monoids. We review the complexity of the intersection problem and raise the issue of limiting the number of final states in the automata involved. In particular, we consider commutative automata with at most two final states and we partially elucidate the complexity of their intersection nonemptiness and related problems. 1
Pentacene-Gate Dielectric Interface Modification with Silicon Nanoparticles for OTFTs
2012-01-01

We report on the properties of pentacene layers and OTFTs (Organic Thin Film Transistors) deposited on semiconductor-gate insulator interfaces covered with silicon nanoparticles (SiNPs) monolayer prepared by the Langmuir-Blodgett method compared to a reference sample (without SiNPs) prepared in an otherwise identical way. To analyse the structural quality, micro-Raman spectroscopy was employed and the correspondence between thin and bulk phase of the integral intensities peaks ratio (α) at 1154 and 1158 cm-1 (α = Int1154 /Int1158) was evaluated. The AFM analysis of the pentacene layers reveals that the different surface treatment of SiO2 gate insulator (hydrophobic or hydrophilic) before SiNPs monolayer deposition has a distinct influence on the formation of different pentacene grain size and morphology. We demonstrate the higher time stability of pentacene OTFT and increasing of saturation current (∼ 2.5 ×) behavior after storage time if the semiconductor-gate insulator interface is modified using a SiNP monolayer.

Microstructure of Monolithic DyBa2Cu3O7-x Coated Conductor Thick Films
2012-01-01

Five μm thick DyBa2Cu3O7-x (DyBCO) films were deposited via Inclined Substrate Deposition (ISD) on Hastelloy substrates. A critical current density of 2.0 MA cm-2 was measured resistively at 77 K and self-field yielding 1000 A cm-1. A grain size of 500-600 nm was determined and only small-angle grain boundaries were observed. The DyBCO film is highly biaxially textured and the c-axis encloses an angle of 27±1̊ with the substrate normal over the complete film thickness. A perfect growth behavior of DyBCO in ISD technology was observed due to the faceted structure of the MgO surface yielding a non-zero component of the growth direction parallel to the (a,b)-plane of the DyBCO.

Comment on Hollan’s “Emerging Issues in the Cross-Cultural Study of Empathy”
2012-01-01

In this comment we take up two points made by Douglas Hollan in his article “Emerging Issues in the Cross-Cultural Study of Empathy,” and discuss their possible philosophical implications. Hollan‘s concept of complex empathy may give rise to the idea that we can learn about other people’s beliefs via empathy, which is something we do not believe is possible. Furthermore, Hollan’s description of possible negative effects of empathy, such as manipulations of a person on the basis of knowledge about their emotions, might pose a problem for proponents of care ethics, who generally start from the assumption that empathy fosters altruistic behavior.
Spermatogonial Stem Cells
2012-01-01

The process of spermatogenesis is initiated and maintained by a rare population of single spermatogonial stem cells (SSCs). The SSCs are attached to the basement membrane of the seminiferous tubules and are characterized by typical morphological criteria. SSCs are the important starting point as part of a robust stem cell system of the testis involved in spermatogenesis and reproduction. The isolation and cultivation of human SSCs would significantly contribute to the increasing knowledge of human germ and stem cell biology. Although still a difficult task, the newly established enrichment and in vitro propagation of spermatogonia that carry the male genome from generation to generation provides an important step for future transplantation and restoration of fertility in the clinic.
Study of the Influence of Construction Materials on the Ageing Properties of High Rate Gas Detectors
2012-01-01

An infrastructure has been set up at the GSI detector laboratory to study the influence of construction materials on the ageing properties of gas filled detectors such as multi wire proportional chambers (MWPC), gas electron multipliers (GEM) etc. As a first step an ageing test of silicone-based glue (RTV-3145)(Dow Corning) has been performed. In this article details of the experimental set-up and the first result on (RTV3145) will be presented.
Do lower extremity kinematics and training variables affect the development of overuse injuries in runners? ‐ a prospective study
2012-01-01

Background The incidence of running injuries appears to be multifactorial, e.g. with regard to training errors or kinematics of the lower extremity [1,2]. To date, studies examining differences between healthy and injured runners are mainly retrospective, and therefore not able to determine whether these differences are the cause or effect of injury. The goal of this prospective study is to evaluate whether the development of overuse injuries in initially healthy subjects is caused by alterations in lower extremity kinematics and/or training habits.
VERITAS and H.E.S.S. observations of the gamma-ray binary HESS J0632+057
2012-01-01

HESS J0632+057 has been recently identified as a new gamma-ray binary system. The source, located in the Monoceros region and associated with the massive Be star MWC 148, shows variability from radio to very high energy (VHE) gamma-rays, displaying a maximum of its non-thermal emission about 100 days after periastron passage (at orbital phases close to 0.3). We present here the results obtained with the VERITAS and H.E.S.S Cherenkov telescopes spanning a wide time interval from 2004 to 2012. The source is detected at TeV gamma-rays at a high significance level at orbital phase 0.3. We also report for the first time TeV observations belonging to orbital phases never explored so far. The VHE gamma-ray results are discussed in a multiwavelength context, focusing on contemporaneous observations obtained with the Swift-XRT.
Influence of turbulence intensity on the flow structure over a thin airfoil at lower reynolds numbers
2012-01-01

Large-scale freestream turbulence commonly present within the atmosphere poses significant challenges to the flight of Micro Air Vehicles. In order to examine the influence of turbulence intensity on the loads occurring over an airfoil, two turbulence conditions of nominally the same longitudinal integral length scale (Lxx/c = 1) but with significantly different intensities (Ti = 7.2% &amp; 12.3%) were generated within a wind tunnel and time-varying surface pressure measurements and smoke flow visualization were made on a thin flat-plate airfoil at Reynolds number relevant to MAV flight. At lower angles of attack, the rapid changes in oncoming flow velocity and direction rendered a large variation in instantaneous flow structure over the airfoil, consequently leading to a significant increase in surface pressure fluctuations. At higher angles of attack, flowfield over the airfoil was noted to be considerably different whereby enhanced rollup of the leading edge separated shear layer occurred. This resulted in the formation of large Leading Edge Vortices which had a significant influence on the aerodynamic loads experienced by the airfoil. The rate of LEV formation was dependent on the angle of attack until 10 degrees and it was independent of the turbulence properties tested.
Direct Democracy in decision making for mega-projects : a new culture of "governance in partnership"?
2012-01-01

There is a growing alienation between the political “ruling class” and regular citizens in most Western societies. This process has become evident also in the increasingly contested decision making procedures for urban and above all transport infrastructure mega-projects. The generally increasing levels of education, consciousness and availability of information have contributed to a worldwide growing demand of citizens to monitor and influence political decision making when it comes to important projects, directly affecting their lives (see e.g. Backlund, Mantysalo, 2010; Harvey, 2008; Healey, 2006; Marcuse, 2012) [1], [2], [3], [4]. As representative democracy alone cannot provide enough possibilities for effective citizens’ involvement, there is a need to complement existing decision making systems with elements of direct democracy, especially when it comes to policy issues of special importance for society (see e.g. Bang, 2005; Bobbio, 2010; Coaffee, J., Healey, P., 2003; Forester, 2011; Galison, 2010; Healey, 2006) [5], [6], [7], [8], [9], [10]. This paper will address this challenge by analysing the multi-level decision making process of an important rail transport infrastructure project in the city of Lindau at Lake Constance that, due to its intense impact on the future urban development options for the Centre for Research on Settlements and Urbanism
[Deficiencies and barriers of the cooperation between German general practitioners and occupational health physicians? A qualitative content analysis of focus groups].
2012-01-01

Similar deficiencies and barriers were mentioned in all three focus groups. The data are helpful in understanding the interface between GPs and OPs in Germany to provide an informative basis for the development of quantitative research instruments for further analysis to improve cooperation. This is the basis for additional cooperation projects.
Putting currency misalignment into gravity: The currency union effect reconsidered
2012-01-01

Member countries of a currency union like the euro area have absorbed asymmetric shocks in ways that are inconsistent with a common nominal anchor. Based on a reformulation of the gravity model that allows for such bilateral misalignment, we disentangle the conventional microeconomic trade effect and macroeconomic trade effects deriving from bilateral misalignment within currency unions. Econometric estimation reveals that for the euro area the misalignment channel exerts a significant trade effect on bilateral exports. We retrieve country-specific estimates of the misalignment-induced effect on trade which demonstrate heterogeneous outlooks across countries for the costs and benefits from adopting the euro.
