Use of orbital cycles to improve magnetostratigraphic dating of drill core SG-1 from the Qaidam Basin (NE Tibetan Plateau) spanning nearly the last ~2.8 Ma
2014-01-01

The ~940-m-long drill core SG-1 consisting of late Pliocene-Quaternary lacustrine sediments from the western Qaidam Basin (NE Tibetan Plateau) serves as a promising archive for studying past climate change. Magnetic susceptibility (χ) was identified as a well-suited proxy for reconstructing past climate of the western Qaidam Basin in a high resolution (~1 ka). The causes for the χ variation related to climate change were previously reduced to the interference of low-temperature oxidation in the catchment and a change of the sediment source regions. To bring the information of past environmental change into a meaningful time frame it is necessary to improve previous magnetostratigraphic dating (~2.8 Ma to 0.1 Ma) of drill core SG-1. Average sediment accumulation rates (SARs) estimated between geomagnetic reversals are in the order of 35 cm/ka. Time series analysis is applied for χ to establish an orbital age model. Results of spectral analysis reveal the response of χ to orbital forcing, including the transition from the dominating 41-ka cycle to the 100-ka cycle around the Mid-Pleistocene Transition (MPT; ~1 Ma). The observed cyclicity of χ is used to establish a cyclostratigraphy that results in an improved age model and depth-to-age transformation of drill core SG-1. The approach includes separation of the core into intervals with different cyclic behaviour and the analysis of sliding windows.
Bar 1-Visibility Graphs and their relation to other Nearly Planar Graphs
2014-01-01

A graph is called a strong (resp. weak) bar 1-visibility graph if its vertices can be represented as horizontal segments (bars) in the plane so that its edges are all (resp. a subset of) the pairs of vertices whose bars have a -thick vertical line connecting them that intersects at most one other bar. We explore the relation among weak (resp. strong) bar 1-visibility graphs and other nearly planar graph classes. In particular, we study their relation to 1-planar graphs, which have a drawing with at most one crossing per edge; quasi-planar graphs, which have a drawing with no three mutually crossing edges; the squares of planar 1-flow networks, which are upward digraphs with in- or out-degree at most one. Our main results are that 1-planar graphs and the (undirected) squares of planar 1-flow networks are weak bar 1-visibility graphs and that these are quasi-planar graphs.
Trumpets and Strumpets: Time, Space, Emulation and Violence in Shakespeare’s Troilus and Cressida
2014-01-01

In this article I examine a number of scenes in Shakespeare’s Troilus&#13;\\nand Cressida where trumpet calls punctuate the action, arguing that they index&#13;\\nforms of early modern masculine warrior identity. The apparently peripheral&#13;\\ntheatrical signs highlight, by means of their acoustic semiosis, forms of masculinity&#13;\\nimbricated in processes of self-perpetuating violence. That spiralling violence&#13;\\nis referred to at one juncture, as a ‘rank feud’ (4.7.16) – a conflict both&#13;\\ngrowing out of control but also one centred around ‘rank’, that is, hierarchical&#13;\\ncompetition generating violence out of violence. I claim that the play, by exploring&#13;\\nthe deeply oxymoronic structure of the masculine warrior ethos, what it&#13;\\nin the context of Hector and Ajax’ duel calls, ‘A gory emulation ’twixt us twain’&#13;\\n(4.7.7), points to broader structures of endemic conflict in early modern English&#13;\\nsociety. The play repeatedly uses the term of imitative ‘emulation’ to index this&#13;\\nphenomenon. Such a term, though referring specifically to internecine aristocratic&#13;\\ncompetition, in turn pointed to wider patterns of violence which were of&#13;\\ngreat concern to contemporaries, but which changes in English society down&#13;\\nthe seventeenth century would gradually make obsolete. The theatre, I suggest,&#13;\\nunwittingly imagined these transformations by its very aesthetic form, ‘[a]nticipating&#13;\\ntime’ in Agamemnon’s phrasing (4.6.2). It did so not out of any uncanny&#13;\\nprescience, but because the early modern theatre’s own variety of imitative&#13;\\n‘emulation’, albeit short-lived, was one sector of an emergent capitalist economy&#13;\\nin whose interests social strife, culminating in the civil wars and the collective&#13;\\ntrauma of 1649, would be increasingly curtailed as the century entered its&#13;\\nlast quarter.

2014-01-01

We report a quantum field theoretical description of light transport and\\nrandom lasing. The Bethe-Salpeter equation is solved including maximally\\ncrossed diagrams and non-elastic scattering. This is the first theoretical\\nframework that combines so called off-shell scattering and lasing in random\\nmedia. We present results for the self-consistent scattering mean free path\\nthat varies over the width of the sample. Further we discuss the density\\ndependent correlation length of self-consistent transport in disordered media\\ncomposed of semi-conductor Mie scatterers.\\n
O naruszaniu podstawowych zasad postępowania naukowego. “Wzgórze przeznaczenia archeologii” górą skandalu
2014-01-01

The article discusses ethical aspects and thoroughness of scientific research on the example of German excavations in Troy, conducted in 1988 by a team from Tübingen University. The author demonstrates how archaeologists became entangled in various relationships with polictical and economic circles, which subsequently yielded an interpretation of findings which ensured financial and media support. The text is an emphatic call for independence and objectivity of scientific investigations that should remain free of any pressure. Although the paper relies on an example from the milieu of archaeologists. historians and classical philologists, the appeal of the authors is a universal one.
Quantum dot laser two-state self-mixing velocimetry: Simulation and experiment
2014-01-01

Compact two-state laser self-mixing is demonstrated. A Doppler signal, originating from the two-state interaction, yields the potential of high-velocity detection. Simulations verify the results and identify the quantum-dot-states carrier coupling as the relevant mechanism for the Doppler signal generation.
EPA-1506 – Impact of brain-derived neurotrophic factor (BDNF) gene polymorphism on cortical inhibition in schizophrenia
2014-01-01

Neuronal plasticity is a characteristic feature of the human central nervous system. Impaired cortical plasticity has been reported to be associated with a val/met gene-polymorphism in the brain-derived neurotrophic factor (BDNF) gene. Based on former studies, impaired cortical plasticity has been described as a common, yet not fully understood phenomenon in patients with schizophrenia. The aim of the study was to investigate the impact of the val/met-BDNF gene-polymorphism on cortical plasticity in patients with schizophrenia. Cortical plasticity was investigated in a cross-sectional sample of schizophrenia patients (SZ) and healthy controls (HC) using anodal and cathodal transcranial direct current stimulation (tDCS) applied to the primary motor cortex inducing long-term potentiation (LTP) and depression (LTD). The after-effect of the applied tDCS was then probed by TMS before and after tDCS stimulation. TMS in all participants was conducted using a standard 70 mm-TMS figure-of-eight magnetic coil connected to a MagPro X 100 magnetic stimulator. Analyses were focused on resting-motor threshold (RMT), 1mV motor-evoked potential (MEP), short-interval intracortical inhibition (SICI at 3 ms), intracortical facilitation (ICF at 12 ms) and cortical silent period (CSP at 120% RMT). The statistical analyses included n=43 SZ and n=44 HC participants (all numbers presented under reserve of further examination) thus resulting in the largest available sample to probe cortical plasticity parameters in BDNF-genotyped schizophrenia patients. Further results will be presented at the conference. The findings will give new insights into the influence of plasticity-associated gene polymorphisms and the pathophysiology of schizophrenia.
EPA-1718 - Neuropathological alterations in FTD cases with C9ORF72 mutation - new insights
2014-01-01

A G4C2 repeat extension in the first intron of C9ORF72 is the most common cause of familial frontotemporal dementia with and without motoneuron disease or atypical Parkinsonism. We recently found that the characteristic p62 positive/TDP43 negative neuronal cytoplasmic inclusions (NCIs) mainly seen in cerebellum und hippocampus consist of different dipeptide repeat proteins (DPRs) generated by an ATG independent translation of stable sense and antisense transcripts of the extended intron. After creating specific antibodies against all potential DPRs resulting from different reading frames, we investigated their regional and cellular distribution pattern in the central nervous system of autopsy cases with C9ORF72 mutation by immunohistochemistry. Aggregates of all DPRs were seen in neuronal cell bodies and processes. Glycine-alanine and glycine-prolin DPRs dominated. NCIs were abundant in all neocortical areas, in the hippocampal formation and in cerebellum, less frequent in subcortical nuclei, and rare in brain stem and spinal cord following a rostro-caudal gradient. Different DPRs were found in the same NCI. The regional distribution pattern of NCIs was similar in all clinical subtypes, and did not directly correlate with neurodegeneration. DPRs and TDP43 that usually also aggregates in C9ORF72 mutation cases were rarely co-localized in the same NCI. In case of co-localization DPR proteins formed a central core surrounded by TDP43. The detection of DPR inclusions directly connects the mutation with specific neuropathological alterations. The formation of DPR inclusions seems to precede the formation of TDP43 inclusions. If there is a neurotoxic effect of DPRs, DPR inclusions might be neuroprotective.
Constrained Willmore tori and elastic curves in 2-dimensional space forms
2014-01-01

In this paper we consider two special classes of constrained Willmore tori in the 3-sphere. The first class is given by the rotation of closed elastic curves in the upper half plane - viewed as the hyperbolic plane - around the x-axis. The second is given as the preimage of closed constrained elastic curves, i.e., elastic curve with enclosed area constraint, in the round 2-sphere under the Hopf fibration. We show that all conformal types can be isometrically immersed into S^3 as constrained Willmore (Hopf) tori and write down all constrained elastic curves in H^2 and S^2 in terms of the Weierstrass elliptic functions. Further, we determine the closing condition for the curves and compute the Willmore energy and the conformal type of the resulting tori.
Use of Synthetic Single-Stranded Oligonucleotides as Artificial Test Soiling for Validation of Surgical Instrument Cleaning Processes
2014-01-01

Surgical instruments are often strongly contaminated with patients’ blood and tissues, possibly containing pathogens. The reuse of contaminated instruments without adequate cleaning and sterilization can cause postoperative inflammation and the transmission of infectious diseases from one patient to another. Thus, based on the stringent sterility requirements, the development of highly efficient, validated cleaning processes is necessary. Here, we use for the first time synthetic single-stranded DNA (ssDNA_ODN), which does not appear in nature, as a test soiling to evaluate the cleaning efficiency of routine washing processes. Stainless steel test objects were coated with a certain amount of ssDNA_ODN. After cleaning, the amount of residual ssDNA_ODN on the test objects was determined using quantitative real-time PCR. The established method is highly specific and sensitive, with a detection limit of 20 fg, and enables the determination of the cleaning efficiency of medical cleaning processes under different conditions to obtain optimal settings for the effective cleaning and sterilization of instruments. The use of this highly sensitive method for the validation of cleaning processes can prevent, to a significant extent, the insufficient cleaning of surgical instruments and thus the transmission of pathogens to patients.
Presence of circulating Her-2 reactive CD8 T cells is associated with a lower frequency of MDSCs and better survival in elderly breast cancer patients
2014-01-01

Meeting abstracts Breast cancer is one of the most common cancers among women. The risk of breast cancer has increased dramatically recently and a higher number of elderly women are being diagnosed with the disease. Myeloid-derived suppressor cells (MDSCs) have been implicated in breast cancer
The Game of Life, Decision and Communication
2014-01-01

The game of life represents a spatial environment of cells that live and die according to fixed rules of nature. In the basic variant of the game a cell’s behavior can be described as reactive and deterministic since each cell’s transition from an actual state to a subsequent state is straight-forwardly defined by the rules. Furthermore, it can be shown that the alive cells’ spatial occupation share of the environment decreases quickly and levels out at a really small value (around 3%), virtually independent of the initial number of alive cells. In this study we will show that this occupation share can be strongly increased if alive cells become more active by making non-deterministic sacrificial decisions according to their individual positions. Furthermore, we applied signaling games in combination with reinforcement learning to show that results can be even more improved if cells learn to signal for navigating the behavior of neighbor cells. This result stresses the assumption that individual behavior and local communication supports the optimization of resourcing and constitute important steps in the evolution of creature and man.
Accretion geometry in the persistent Be/X-ray binary RXJ0440.9+4431
2014-01-01

The persistent Be/X-ray binary RXJ0440.9+4431 flared in 2010 and 2011 and has been followed by various X-ray facilities (Swift, RXTE, XMM-Newton, and INTEGRAL). We studied the source timing and spectral properties as a function of its X-ray luminosity to investigate the transition from normal to flaring activity. The source spectrum can always be described by a bulk-motion Comptonization model of black body seed photons attenuated by a moderate photoelectric absorption. At the highest luminosity, we measured a curvature of the spectrum, which we attribute to a significant contribution of the radiation pressure in the accretion process. This allows us to estimate that the transition from a bulk-motion-dominated flow to a radiatively dominated one happens at a luminosity of ~ 2 × 1036 erg s−1. The luminosity dependency of the size of the black body emission region is found to be rBB ∝ LX 0.39±0.02. This suggests that either matter accreting onto the neutron star hosted in RXJ0440.9+4431 penetrates through closed magnetic field lines at the border of the compact object magnetosphere or that the size of the black-body emitting hotspot is larger than the footprint of the accretion column. This phenomenon can be due to illumination of the surface by a growing column or by a a structure of the neutron star magnetic field more complicated than a simple dipole at least close to the surface.
Public sector labour relations in four European countries compared : Long-term convergence and short-term divergences?
2014-01-01

This paper focuses on the impact of the 2007/2008 financial and economic crisis on the public sector and its labour relations in Spain, the UK, Sweden and Germany. The analysis of the contextual background - general and societal economic developments as well as industrial relations - in which such transformations happened embeds the comparison of the four country case studies. Our findings show that the crisis and austerity policies furthered some short-term divergent developments of the public sectors in the countries considered but long-term convergence can be also expected. Some theoretical conclusions from these mixed developments in the aftermath of the crisis are drawn.
Expatriation strategies for the adaptation of employment modes to different market economies
2014-01-01

Despite the strategic importance of expatriation for multinational companies (MNC) and its relevance for managing the workforce of overseas subsidiaries, how expatriation strategies are associated with the adaptation of employment modes to different market economies has only rarely been examined. This exploratory study combines three different bodies of literature, the Varieties of Capitalism approach, the international business literature and the expatriation literature, to examine the employment modes of 76 subsidiaries of U.S. MNCs in a Coordinated Market Economy (Germany), a Hybrid Market Economy (Switzerland), and a Liberal Market Economy (United Kingdom). We find substantial differences in the expatriation strategies of MNCs depending, first, on the differences between the institutional environment of the parent company and that of the subsidiary and, second, on the international focus of the MNC. By exploring the variations between these factors we explain four expatriation strategies of idiosyncratic associations with the adaptation of employment modes: ambiguous expatriation, substantive expatriation, substantive non-expatriation and balanced non-expatriation. We hence provide first insights into how expatriation and the adaptation of employment modes to market economies can be effectively combined.
Dibaryons – a new state of matter?
2014-01-01

New results in the field of dibaryons are discussed concentrating on the d (2380) resonance with I(J ) = 0(3 ), which has been observed first in the double-pionic fusion to deuterium and meanwhile also in neutron-proton scattering — establishing it thus as a genuine s-channel resonance. Double-pionic fusion reactions to the He isotopes demonstrate that this resonance survives also in a nuclear surrounding. It also has been shown to contribute to dilepton production helping thus to resolve the so-called DLS puzzle. Moreover, the existence of dibaryons has also an impact on the equation of state for nuclear matter.
“I DON’T KNOW A MAN WHO ISN’T KNEE-DEEP IN IT”: INTERSECTIONS OF AGE AND GENDER IN OLDER PEOPLE’S INTERNET USE
2014-01-01

Older people use the internet less than younger people, and older women less than older men (Office for National Statistics, 2014). This presentation examines intersections of age and gender in older people's internet use. The research perspective combines a focus on technology adoption in the tradition of domestication theory with the understanding of gender-technology relations developed in feminist technology studies, and research on ageing. Findings from a sociological study conducted in the North East of the UK, based on 33 semi-structured interviews with women and men between the ages of 55 and 80 about their computer and internet use are presented, demonstrating the significance of traditional age-gender-technology relations and the variety of outcomes of intersections between gender and age in older people's internet use.
"The Power of Words we RARELY Use: Dignity, Rights and Responsibility"
2014-01-01

Words matter, but some words are seldom used in management discourse— and that gap has important implications for what is and is not considered relevant for research, teaching, and management practice. In particular, we argue that organizational research should connect more directly with other social sciences to update and enlarge its theoretical repertoire to encompass core elements of humanism, particularly the concepts of human dignity, rights, and responsibilities. Specifically, we propose articulating that connection with the social sciences around three main terms (words): 1) The notion of human dignity which has played a central role in many social sciences, and is credited as a main driver of economic and civilizational progress (Kateb, 2011; McCloskey, 2010; Rosen, 2012). 2) The notion of human rights, which is a mainstay of many social sciences but rarely gets treatment within management other than in business ethics(Levy & Sznaider, 2010; McEldowney & Weick, 2003; Meyer & Parent, 1992; Wettstein, 2009, 2009 ), and 3) The notion of responsibility, which has gained more traction in the discourse on management, as the term CSR has gained increasing visibility (Carroll, 1999; Matten & Moon, 2008; Waddock, 2008; Waddock, Bodwell, & Graves, 2002). We suggest, however, that responsibility is critical for sustainable social well-being and without a connection to the prior two terms remains an anemic concept. After a short introduction on the power of the words we RARELY use, specifically, dignity, rights, and responsibilities, Claus Dierksmeier (University of Tuebingen) will outline the central notion of human dignity. Florian Wettstein (University of St. Gallen) will build on the notion of human dignity and will outline the genesis of human rights and their role within management research. Sandra Waddock (Boston College) will argue that well-being should be the central construct in management and economic thinking—with human dignity as the foundational value creating attendant rights and responsibilities for businesses, and by implication, management scholarship. After discussion, the panel will entertain questions and answers from the audience with the goal to inform business school researchers and teachers on how such words could be used more frequently and help management theory to increase accuracy and relevance.

Low Cost Activity Recognition Using Depth Cameras and Context Dependent Spatial Regions (Extended Abstract)
2014-01-01

Recognition of human activities is usually based on expensive sensor setups to extract rich information such as body posture or object interaction. We investigate the use of inexpensive depth cameras to perform activity recognition using context dependent spatial regions with two dierent approaches: Spatio-Temporal Plan Representations and Hierarchical Hidden Markov Models. We evaluate both approaches in a simulated and a real-world environment.
A Human Morning Routine Dataset (Extended Abstract)
2014-01-01

To be able to evaluate and compare the quality of dierent approaches in research, general and publicly available datasets are needed. While in some areas, there exists a variety of such datasets that are constantly used by researchers, in the area of activity recognition and human activity modelling, the number of publicly available datasets is rather small. In this extended abstract, we introduce a new dataset that captures several typical activities of a human morning routine of a single male person that includes motion tracking data for the person and objects from real sensors and a simulation as well as ground truth information in the form of diary notes. The dataset is intended to ease comparison between dierent approaches in the afrementioned research areas and free researchers from the time-consuming task of recording new datasets.
Visibly Counter Languages and Constant Depth Circuits.
2014-01-01

We examine visibly counter languages, which are languages recognized by visibly counter automata (a.k.a. input driven counter automata). We are able to effectively characterize the visibly counter languages in AC^0 and show that they are contained in FO[+].
