Redefining educational excellence: The 2024 perspective of the de.NBI / ELIXIR-DE training Platform
Creators: name: Wibberg, Daniel
Publisher: name: F1000 Research Limited
Year: 2024

description: Over recent years, the German ELIXIR node has developed an extensive and diverse training programme for the services offered. Between 2015 and 2024, de.NBI and ELIXIR-DE have organised almost 500 training courses, benefiting over 10,000 participants.  In the course of implementing a sustainability process for the German Node, coinciding with the renewal of our ELIXIR Cooperation Agreement in December 2023, the de.NBI consortium has been restructured. After two years of reorganisation, the consortium is now fully operational.

With the re-launch of de.NBI and ELIXIR Germany, there is an ongoing phase of redevelopment for the de.NBI / ELIXIR-DE training activities. The de.NBI / ELIXIR-DE training platform is shifting its focus more towards teaching, strategic aspects of training, fostering training collaborations within Germany (e.g. with different NFDIs) and Europe (e.g. with ELIXIR Austria & ELIXIR Luxembourg), developing  new training courses and forming communities of trainers. In addition, the de.NBI / ELIXIR-DE training platform is increasingly involved in the organisation of training highlight events, e.g. de.NBI Spring / Summer Schools and BioHackathon Germany.

Following the restructuring, the de.NBI / ELIXIR-DE training platform will be well equipped to address the forthcoming challenges of bioinformatics training in Germany and Europe in the coming years.

description: Die Autoren des „Hanyu jieguo buyu dapei cidian“ stellen in diesem Bericht die Ergebnisse ihrer Untersuchung zum Ergebniskomplement (EK) vor. Dank ihrer großen Flexibilität wird die Verb-EK-Struktur beim Sprechen spontan gebildet und bereitet daher dem Chinesischlernenden besondere Schwierigkeiten. Bei den Verben der Verb-EK-Struktur handelt es sich 1.) um Verben, die eindeutig eine Tätigkeit bezeichnen, 2.) um Verben mit einfacher Aussprache (meistens einsilbige Verben), 3.) um Verben mit sehr allgemeiner Bedeutung und 4.) um zweisilbige Verben, die ihrerseits bestimmte Bedingungen erfüllen müssen. Als EK treten entweder Komplemente mit „sichtbarer Gestalt“ oder „formlose“ Komplemente auf. Aus einem Adjektiv gebildete EK beschreiben in erster Linie Zustände, aus einem Verb gebildete EK beschreiben Gefühle, physikalische Zustände und Anfang, Veränderung oder Auflösung einer Handlung. Bei der Beziehung zwischen Verb und EK handelt es sich im allgemeinen um – sowohl direkte als auch indirekte – Ursache-Wirkung-Beziehungen. Zu jedem Punkt ihrer Untersuchung nennen die Autoren zahlreiche Beispiele und Beipielsätze.

description: In [1] M. Baker and S. Norine developed a theory of divisors and linear systems on graphs, and proved a Riemann-Roch Theorem for these objects (conceived as integer-valued functions on the vertices). In [2] and [3] the authors generalized these concepts to real-valued functions, and proved a corresponding Riemann-Roch Theorem in that setting, showing that it implied the Baker-Norine result. In this article we prove a Riemann-Roch Theorem in a more general combinatorial setting that is not necessarily driven by the existence of a graph.

Creators: name: MintesnotBeyene
Publisher: name: Zenodo
Year: 2016

description: This study examines governance and public service delivery of water supply in Akaki-kality sub-city. The key objectives of the study are: assess the effectiveness of the government system in water supply service delivery with respect to CAR frame work, assess the satisfaction of clients in water service delivery in Akaki-kality sub-city and to show the major obstacles of water service. Qualitative and semi-quantitative methods with stratified sampling are used in the study. Beside that key-informant interview also apply in the study. The study covers availability and accesses of water to observe the satisfaction of the clients more than 50% of the respondent are not satisfied with water service supply in Akaki-kality sub-city. With regard to effectiveness of government system most of the respondents disagree about effectiveness of the system. Findings show that lack of transparency, accountability and responsiveness are obvious in water service supply, restriction of private sector in the supply of potable drinking water with pipe line, the community forums role is insignificant in decision making of water service and NGO’s play great role in providing drinking water for Akaki-kality clients

In particular we prove that if a partially hyperbolic diffeomorphism is accessible, then either the set with finite peaks for the Jacobian cocycle is of full volume, or the set of transitive points is of positive volume.
Transport-driven toroidal rotation in the tokamak edge

Publisher: name: arXiv
Year: 2011
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: The interaction of passing-ion drift orbits with spatially-inhomogeneous but purely diffusive radial transport is demonstrated to cause spontaneous toroidal spin-up to experimentally-relevant values in the tokamak edge. Physically, major-radial orbit shifts cause orbit-averaged diffusivities to depend on parallel velocity, including its sign, leading to residual stress. The resulting intrinsic rotation scales with ion temperature over poloidal magnetic field strength, resembling typical experimental scalings. Additionally, an inboard (outboard) X-point is expected to enhance co- (counter-) current rotation.

Low Frequency (11 mHz) Oscillations in H1743-322: A New Class of Black Hole QPOs?
Creators: name: Altamirano, Diego
name: Strohmayer, Tod
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We report the discovery of quasi-periodic oscillations (QPO) at ~11 mHz in two RXTE observations and one Chandra observation of the black hole candidate H1743-322. The QPO is observed only at the beginning of the 2010 and 2011 outbursts at similar hard colour and intensity, suggestive of an accretion state dependence for the QPO. Although its frequency appears to be correlated with X-ray intensity on timescales of a day, in successive outbursts eight months apart we measure a QPO frequency that differs by less than ~2.2 mHz while the intensity had changed significantly. We show that this ~11 mHz QPO is different from the so-called Type-C QPOs seen in black holes and that the mechanisms that produce the two flavours of variability are most probably independent. After comparing this QPO with other variability phenomena seen in accreting black holes and neutron stars, we conclude that it best resembles the so-called "1 Hz" QPOs seen in dipping neutron star systems, although having a significantly lower (1-2 orders of magnitude) frequency. If confirmed, H1743-322 is the first black hole showing this type of variability. Given the unusual characteristics and the hard-state dependence of the ~11 mHz QPO, we also speculate whether these oscillations could instead be related to the radio jets observed in H1743-322. A systematic search for this type of low-frequency QPOs in similar systems is needed to test this speculation. In any case, it remains unexplained why these QPOs have only been seen in the last two outbursts of H1743-322.

In questo contesto vengono messe a confronto le accademie linguistiche che da tempo in Italia, Francia e Croazia hanno una forte influenza sull’imposizione delle norme e godono di ampio prestigio se messe a confronto invece con le attività dall’ambizione politico-linguistica di quei paesi, nei quali non esistono istituzioni di questo tipo. Tutte le istituzioni e le associazioni, indipendentemente dalla loro collaborazione con lo Stato o con le Società, hanno in comune la volontà – autoattribuita – di impegnarsi nella cura della lingua nel proprio contesto sociale.

Current induced magnetization reversal on the surface of a topological insulator
Creators: name: Yokoyama, Takehito
Publisher: name: arXiv
Year: 2011
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We study dynamics of the magnetization coupled to the surface Dirac fermions of a three di- mensional topological insulator. By solving the Landau-Lifshitz-Gilbert equation in the presence of charge current, we find current induced magnetization dynamics and discuss the possibility of mag- netization reversal. The torque from the current injection depends on the transmission probability through the ferromagnet and shows nontrivial dependence on the exchange coupling. The mag- netization dynamics is a direct manifestation of the inverse spin-galvanic effect and hence another ferromagnet is unnecessary to induce spin transfer torque in contrast to the conventional setup.

The mid-infrared extinction in molecular clouds Case study of B 335
Creators: name: Olofsson, Sven
name: Olofsson, Göran
Publisher: name: arXiv
Year: 2011
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The purpose of the investigation is to probe the dust properties inside a molecular cloud, how particle grow and how the presence of ice coatings may change the overall shape of the extinction curve. Field stars can be used to probe the cloud extinction. By combining multi-colour photometry and IR spectroscopy the spectral class of the star can be determined as can the extinction curve. We determine the reddening curve from 0.35 to 24 μm. The water ice band at 3.1 μm is weaker (τ(3.1) = 0.4) than expected from the cloud extinction (AV \approx 10 for the sightline to the most obscured star). On the other hand, the CO ice band at 4.7 μm is strong (τ(4.67) = 0.7) and indicates, that the mass column density of frozen CO is about the same as that of water ice. We show that the reddening curves for the two background stars, for which the silicate band has been measured, can be accurately modelled from the UV to 24 μm. These models only include graphite and silicate grains. No need for any additional major grain component to explain the slow decline of the reddening curve beyond the K band. The dust model for the dense part of the cloud has more large grains than for the rim. We propose that the well established shallow reddening curve beyond the K band has two different explanations: larger graphite grains in dense regions and relatively small grains in the diffuse ISM, giving rise to substantially less extinction beyond the K band than previously thought. For the sight line towards the most obscured star, we derive the relation AKs = 0.97 \cdot E(J - Ks), and assuming that all silicon is bound in silicates, N(2 H2 +H) \approx 1.5 \times 10^{21} \cdot AV \approx 9 \times 10^{21} \cdot AKs. For the rim of the cloud we get AKs = 0.51 \cdot E(J - Ks), which is close to recent determinations for the diffuse ISM. The corresponding gas column density is N(2 H2 +H) \approx 2.3 \times 10^{21} \cdot AV \approx 3 \times 10^{22} \cdot AKs.

description: The interpretation of the measured elliptic and higher order collective flows in heavy-ion collisions in terms of viscous hydrodynamics depends sensitively on the ratio of shear viscosity to entropy density. Here we perform a quantitative comparison between the results of shear viscosities from the Chapman-Enskog and relaxation time methods for selected test cases with specified elastic differential cross sections: (i) The non-relativistic, relativistic and ultra-relativistic hard sphere gas with angle and energy independent differential cross section (ii) The Maxwell gas, (iii) chiral pions and (iv) massive pions for which the differential elastic cross section is taken from experiments. Our quantitative results reveal that (i) the extent of agreement (or disagreement) depends sensitively on the energy dependence of the differential cross sections employed, and (ii) stress the need to perform quantum molecular dynamical (URQMD) simulations that employ Green-Kubo techniques with similar cross sections to validate the codes employed and to test the accuracy of other methods.

description: Nanosheets of nickel with thickness equal to 0.6 nm have been grown within the interlayer spaces of Na-4 mica. The sheets are made up of percolative clusters of nanodisks. Magnetization characteristics indicate a superparamagnetic behavior with a blocking temperature of 428 K.The magnetic anisotropy constant as extracted from the coercivity data has been found to be higher than that of bulk nickel by two orders of magnitude. This is ascribed to a large aspect ratio of the nickel nanophase. The Bloch exponent is also found to be considerably different from that of bulk nickel because of a size effect. The Bloch Equation is still found to be valid for the two dimensional structures.

Absorption of Gamma-Ray Photons in a Vacuum Neutron Star Magnetosphere: II. The Formation of "Lightnings"

subject: FOS: Physical sciences

description: The absorption of a high-energy photon from the external cosmic gamma-ray background in the inner neutron star magnetosphere triggers the generation of a secondary electron-positron plasma and gives rise to a lightning - a lengthening and simultaneously expanding plasma tube. It propagates along magnetic fields lines with a velocity close to the speed of light. The high electron-positron plasma generation rate leads to dynamical screening of the longitudinal electric field that is provided not by charge separation but by electric current growth in the lightning. The lightning radius is comparable to the polar cap radius of a radio pulsar. The number of electron-positron pairs produced in the lightning in its lifetime reaches 10^28. The density of the forming plasma is comparable to or even higher than that in the polar cap regions of ordinary pulsars. This suggests that the radio emission from individual lightnings can be observed. Since the formation time of the radio emission is limited by the lightning lifetime, the possible single short radio bursts may be associated with rotating radio transients (RRATs).

This observational sample offers a broad variety of comets, solar wind environments and observational conditions. It clearly demonstrates that solar wind charge exchange emission provides a wealth of diagnostics, which are visible as spatial, temporal, and spectral emission features. We review the possibilities and limitations of each of those in this contribution.

description: In the present paper, optical anisotropy effects in architectural glass are evaluated using digital image processing. Hereby, thermally toughened glass panes were analyzed quantitatively using a circular polariscope. Glass subjected to externally applied stresses or residual stresses becomes birefringent. Polarized light on birefringent materials causes interference colors (iridescence), referred to as anisotropies, which affect the optical appearance of glass panes in building envelopes. Thermally toughened glass, such as toughened safety glass or heat strengthened glass, show these iridescences due to thermally induced residual stress differences. RGB-photoelastic full-field methods allow the quantitative measurement of anisotropies, since the occurring interference colors are related to the measured retardation values. By calibrating the circular polariscope, retardation images of thermally toughened glass panes are generated from non-directional isochromatic images using computer algorithms. The analysis of the retardation images and the evaluation of the anisotropy quality of the glass is of great interest in order to detect and sort out very low quality glass panes directly in the production process. Therefore, in this paper retardation images are acquired from different thermally toughened glass panes then different image processing methods are presented and applied. It is shown that a general definition of exclusion zones, e.g. near edges is required prior to the evaluation. In parallel, the limitations in the application of first-order statistical and threshold methods are presented. The intend of the investigation is the extension of the texture analysis based on the generation of Grey Level Co-occurrence Matrices, where the spatial arrangement of the retardation values is considered in the evaluation. For the first time, the results of textural features of different glass pane formats could be compared using reference areas and geometry factors. By reduction of the original image size, the computation time of textural analysis algorithms could be remarkably speeded up, while the textural features remained the same. Finally, the knowledge gained from these investigations is used to determine uniform texture features, which also includes the pattern of anisotropy effects in the evaluation of thermally toughened glass. Together with a global evaluation criterion this can now be implemented in commercial anisotropy measurement systems for quality control of tempered architectural glass.

description: In order to study the acceleration and propagation of bremsstrahlung-producing electrons in solar flares, we analyze the evolution of the flare loop size with respect to energy at a variety of times. A GOES M3.7 loop-structured flare starting around 23:55 on 2002 April 14 is studied in detail using \textit{Ramaty High Energy Solar Spectroscopic Imager} (\textit{RHESSI}) observations. We construct photon and mean-electron-flux maps in 2-keV energy bins by processing observationally-deduced photon and electron visibilities, respectively, through several image-processing methods: a visibility-based forward-fit (FWD) algorithm, a maximum entropy (MEM) procedure and the uv-smooth (UVS) approach. We estimate the sizes of elongated flares (i.e., the length and width of flaring loops) by calculating the second normalized moments of the intensity in any given map. Employing a collisional model with an extended acceleration region, we fit the loop lengths as a function of energy in both the photon and electron domains. The resulting fitting parameters allow us to estimate the extent of the acceleration region which is between $\sim 13 \rm{arcsec}$ and $\sim 19 \rm{arcsec}$. Both forward-fit and uv-smooth algorithms provide substantially similar results with a systematically better fit in the electron domain.The consistency of the estimates from these methods provides strong support that the model can reliably determine geometric parameters of the acceleration region. The acceleration region is estimated to be a substantial fraction ($\sim 1/2$) of the loop extent, indicating that this dense flaring loop incorporates both acceleration and transport of electrons, with concurrent thick-target bremsstrahlung emission.

description: We discuss computational analysis of phononic thermal conduction in the suspended membrane geometry, in the experimentally commonly appearing case where heat can flow out radially in two dimensions from a central source. As we are mostly interested in the low-temperature behavior where bulk scattering of phonons becomes irrelevant, we study the limit where all phonon scattering takes place at the membrane surfaces. Moreover, we limit the discussion here to the case where this surface scattering is fully diffusive, the so called Casimir limit. Our analysis shows that in the two-dimensional case, no analytic results are available, in contrast to the well known 1D Casimir limit. Numerical solutions are presented for the temperature profiles in the membrane radial direction, for several different membrane thicknesses. Our results can be applied, for example, in the design of membrane-supported bolometric radiation detectors.

description: We study the Chern-Simons action, which was defined for noncommutative spaces in general by the author, for the noncommutative 3-torus, the universal C*-algebra generated by 3 unitaries. D. Essouabri, B. Iochum, C. Levy, and A. Sitarz constructed a spectral triple for the noncommutative 3-torus. We compute the Chern-Simons action for this noncommutative space. In connection with this computation we calculate the first coefficient in the loop expansion series of the corresponding Feynman path integral with the Chern-Simons action as Lagrangian. The result is independent of the deformation matrix of the noncommutative 3-torus and always 0.

description: Polymer chemical enhanced oil recovery (EOR) is a tertiary method of oil production that helps to improve the recovery of hydrocarbons in the late stages of a reservoir’ s life. This method of EOR increases the amount of unswept or residual oil produced by displacing and driving the fluids towards a producing well. Polymers are used in chemical EOR to improve the mobility ratio. The objectives of this research were to develop a predictive model to find the shear rate versus viscosity of a polymer sample without the need for lab input data, to create a program to model and validate the accuracy of large data sets simultaneously, and to combine common polymer calculations/programs into a Master Polymer Tool. This multi-faced work involved the use of lab work, numerous modeling techniques, and programming to achieve these outlined objectives. The predictive model was able to model the rheology of a polymer sample, while the program efficiently processed large amounts of polymer rheology data for modeling, quality validation, and to observe a macroscopic analysis of polymer behavior. Though there is a wide degree of variability in polymer data – in large part due to inconsistencies in preparation – current predictive modeling techniques were found to be accurate indicators of rheological behavior. Numerous other programs and spreadsheets related to polymer EOR were updated and combined into a Master Polymer Tool to provide researchers and engineers with a “ one stop shop” for commonly used calculations.

description: A number of computations exist, especially in area of error-control coding and matrix computations, whose underlying data flow graphs are based on finite projective-geometry(PG) based balanced bipartite graphs. Many of these applications are actively being researched upon. Almost all these applications need bipartite graphs of the order of tens of thousands in practice, whose nodes represent parallel computations. To reduce its implementation cost, reducing amount of system/hardware resources during design is an important engineering objective. In this context, we present a scheme to reduce resource utilization when performing computations derived from PG-based graphs. In a fully parallel design based on PG concepts, the number of processing units is equal to the number of vertices, each performing an atomic computation. To reduce the number of processing units used for implementation, we present an easy way of partitioning the vertex set. Each block of partition is then assigned to a processing unit. A processing unit performs the computations corresponding to the vertices in the block assigned to it in a sequential fashion, thus creating the effect of folding the overall computation. These blocks have certain symmetric properties that enable us to develop a conflict-free schedule. The scheme achieves the best possible throughput, in lack of any overhead of shuffling data across memories while scheduling another computation on the same processing unit. This paper reports two folding schemes, which are based on same lattice embedding approach, based on partitioning. We first provide a scheme for a projective space of dimension five, and the corresponding schedules. Both the folding schemes that we present have been verified by both simulation and hardware prototyping for different applications. We later generalize this scheme to arbitrary projective spaces.

description: A new explicit construction of Cauchy-Fantappié kernels is introduced for an arbitrary weakly pseudoconvex domain with smooth boundary. While not holomorphic in the parameter, the new kernel reflects the complex geometry and the Levi form of the boundary. Some estimates are obtained for the corresponding integral operator, which provide evidence that this kernel and related constructions give useful new tools for complex analysis on this general class of domains.

description: The effect of the local fields on the absorption spectra of silicon nanoclusters (NCs), freestanding or embedded in SiO2, is investigated in the DFT-RPA framework for different size and amorphization of the samples. We show that local field effects have a great influence on the optical absorption of the NCs. Their effect can be described by two separate contributions, both arising from polarization effects at the NC interface. First, local fields produce a reduction of the absorption that is stronger in the low energy limit. This contribution is a direct consequence of the screening induced by polarization effects on the incoming field. Secondly, local fields cause a blue shift on the main absorption peak that has been explained in terms of perturbation of the absorption resonance conditions. Both contributions do not depend either on the NC diameter nor on its amorphization degree, while showing a high sensitivity to the environment enclosing the NCs.

description: Gastroschisis is a congenital birth defect in which an infant is born with a hole in its abdomen, allowing its internal organs to rest outside of the body. Medical solutions currently exist to resolve this problem, such as primary fascial closure, sutureless surgery, and inserted silos for the staged reduction of the protruding organs. However, treatment for this defect can lead to long hospital stays and exorbitant medical bills. In an attempt to create a new method of treatment to reduce these negative effects, testing was conducted to evaluate the feasibility of an inflatable silo ring that could actively close the abdominal defect through inflation. Variations of this theoretical device were first simulated in SOLIDWORKS to discover what designs were most well suited for abdominal insertion. Selected designs were subsequently verified through physical prototyping and measurement.
