The interest in bottom-up fabricated semiconductor nanowires (NWs) has been growing steadily in the last years due to their potential as basic building blocks of nanoscale devices and circuits. Investigations performed so far try to exploit three unique properties of NWs: First, they are the smallest dimension structures that allow optical guiding and electrical contacting simultaneously. Second, their large surface to volume ratio enhances their interaction with the environment, turning them into optimal chemical and biological sensors. Finally, their anisotropic geometry makes their optical and electrical properties dramatically dependent on their orientation, allowing their use as polarization-dependent sensors. Most NW applications rely on the ability to grow, characterize (structurally, optically and electronically) and manipulate both individual and collections of NWs. To date it is rather difficult to find a single research group covering all of the above competences, and students (or post-docs) usually focus on a single aspect of NW-based device realization (either growth, characterization, simulation or device assembly). The scope of this project is to create a European Network of experienced teams that will provide early stage researchers with a multidisciplinary framework and a comprehensive training in the field of NW physics and applications. The active involvement of industrial partners will ensure that the acquired competences are driven by industrial needs, such as scalable and low cost NW production. The interaction with associated industrial partners will also add to the employability of the recruited researchers through the exposure to the private sector. The main applications that we intend to address within the project time are the following: (i) nanowires for sensing applications, (ii) nanowires for optoelectronics (iii) nanowires for nanoelectronics and (iv) nanowires for energy harvesting.

Internal motions of proteins are essential to their function. The time dependence of protein structural fluctuations is highly complex, manifesting subdiffusive, non-exponential behaviour with effective relaxation times existing over many decades in time, from ps up to ∼10 2 s (refs,). Here, using molecular dynamics simulations, we show that, on timescales from 10 -12 to 10 -5 s, motions in single proteins are self-similar, non-equilibrium and exhibit ageing. The characteristic relaxation time for a distance fluctuation, such as inter-domain motion, is observation-time-dependent, increasing in a simple, power-law fashion, arising from the fractal nature of the topology and geometry of the energy landscape explored. Diffusion over the energy landscape follows a non-ergodic continuous time random walk. Comparison with single-molecule experiments suggests that the non-equilibrium self-similar dynamical behaviour persists up to timescales approaching the in vivo lifespan of individual protein molecules. © 2016 Macmillan Publishers Limited.

The proposal aims at strengthening research partnerships through staff exchanges and networking activities between 2 European research organisations from Germany and Spain, and 2 research organisations from Argentina and Brazil. The scientific objective is to create a co-evolvement process towards a successful management model for SMEs that combines the European innovation and organizational learning model with Latin American survival strategies in turbulent economies (exemplified by Argentina and Brazil) based on learning networks and clusters. Both, in Europe and Latin America, SMEs are the most important sources of job creation and development in increasingly knowledge based economies. The economic environment in which SMEs operate, however, have differed significantly until recently. As the turbulence of the global economy is increasing European SMEs will have to learn to remain competitive in this new kind of economic environment. The answer lies in the development of dynamic capabilities of innovating, learning and knowledge management by SME networks. Following established theories and practices of organisational and social learning knowledge research activities are conceived as a joint learning and co-evolvement cycle in four phases Creating a joint vision,Learning from European approaches, Co-evolve SME model and practice in Argentina and Brazil,IHarvest and sustain. To achieve this objective a joint learning and co-evolvement process will be developed by four international research teams focusing on 1)Developing dynamic capabilities via SME networks and 2) via SME clusters , 3)Media \ tools for developing dynamic capabilities, 4) monitoring dynamic capability development The proposed project will create 4 major impacts:1. A new understanding of sustainable SME management in turbulent economies. 2.Improved innovation and learning capabilities of SMEs. 3.A lasting community of scholars. 4. Wide dissemination and leverage to key actors

Interactive Storytelling is a major endeavour to develop new media which could offer a radically new user experience, with a potential to revolutionise digital entertainment. European research in Interactive Storytelling has played a leading role in the development of the field, and this creates a unique opportunity to strengthen its position even further by structuring some of its best actors within a NoE. \nIRIS (Integrating Research in Interactive Storytelling) aims at creating a virtual centre of excellence that will be able to achieve breakthroughs in the understanding of Interactive Storytelling and the development of corresponding technologies. It is organised around four major objectives:\t\nTo extend Interactive Storytelling technologies in terms of performance and scalability, so that they can support the production of actual Interactive Narratives \nTo make the next generation of Interactive Storytelling technologies more accessible to authors and content creators of different media backgrounds (scriptwriters, storyboarders, game designers) \nTo develop a more Integrated Approach to Interactive Storytelling Technologies, achieving a proper integration with cinematography \nTo develop Methodologies to evaluate Interactive Storytelling systems as well as the media experience of Interactive Narrative\nThe Joint Programme of Activities integrates complementary skills which are necessary to address the above objectives (e.g. integration with cinematography, authoring, evaluation, user interaction techniques). It benefits from the integration of extensive partners background, but also plans to revisit existing research programmes from the perspective of collaboration (e.g. revisiting Interactive Storytelling technologies from the perspective of authoring and cinematography).
Medical Care for Homeless People - Individual Right and a Social Duty for an Inclusive Society [Medizinische Versorgung für wohnungslose Menschen - individuelles Recht und soziale Pflicht statt Exklusion]

Homelessness is a social phenomenon of increasing frequency in Germany and of high relevance for an inclusive society. Its expression is both caused psychosocially and moderated socioeconomically, often with negatively reinforcing feedback-loops. This overview describes health effects and strategies for improvement, using the example of the "Mainzer Modell". The comprehensive availability of adequate medical care are both an individual right and a social duty for an inclusive society. © Georg Thieme Verlag KG.

The introduction of modern model-driven software development methodologies into the industrial practise still proves to be a challenge. Especially small or medium-sized enterprises (SMEs) need an incremental and continuous modernisation process, which incorporates existing projects, is customised and cost-effective. Particularly, suitable solutions for model-based or -driven testing with test automation to increase the efficiency are in demand. This paper presents an approach for integrating existing proprietary system models of an SME partner for describing industrial automation processes into a model-driven test process, utilising a domainspecific language for the test specification. The test objectives focuses on the correct implementation of the communication and synchronisation of distributed state machines. The presented approach is integrated into a test framework, which is based on the Eclipse Modelling Framework (EMF) and the Eclipse Test and Performance Tools Platform Project (TPTP) framework. To separate the possibly changeable system and DSLspecific models from the implementation of the test framework, a stable and more generic test meta model was defined.

Wireless Sensor Network technologies are maturing into industrial applicability, but the availability of broadly supported architectures and integration of existing standards is still lagging behind. As a proposal to ameliorate this situation, we consider the OMG Data Distribution Service (DDS), a middleware standard for interoperable data-centric publish/subscribe architectures with real-time capabilities, a candidate for standards-based realisations of equally data-centric WSN scenarios. DDS is rooted in larger-scale architectures. Consequently, the RTPS network protocol defined as a sibling standard to DDS assumes Ethernet-sized network frames and substantial communication resources, which are potential obstacles to applying DDS to WSNs. We therefore propose SNPS as an alternative transport protocol for DDS communication. SNPS has been designed as part of sDDS, a model-driven DDS realization architecture supporting highly resource-constrained embedded sensor node platforms. Still, SNPS is generally independent of sDDS; it was demonstrated to be usable even with minimalist solutions lacking a proper DDS run-time system. For SNPS, a modular layered architecture focussing on minimum footprint and scalability was defined. SNPS packets are assembled from an extensible set of submessages that are chosen and filled according to a well-defined, unambiguous protocol state engine. Keeping a stack of context information for a stream of SNPS submessages minimizes explicit state representation in the resulting packet structure. Other aspects of the protocol design are the support for bundling of data to minimize the total number of link layer frames exchanged and the leveraging of multi- and broadcast properties of wireless sensor networks. Most of the features are beneficial for wired sensor networks as well. SNPS has been implemented for several wireless and wired network protocols (ZigBee, 6LoWPAN, and Ethernet/UDP/IP) on diverse embedded sensor node and PC platforms. It has been embedded in the sDDS architecture and integrated into minimalist standalone implementations. It will be the main DDS transport protocol used at sensor integration levels of current projects of the authors' laboratory research group targeting home and industrial automation scenarios. © 2012 Universitat Klagenfurt.
Application of the logarithmic normal distribution in material testing: Misleading norm statements resulting in faulty analyses [Zur Anwendung der logarithmischen Normalverteilung in der Materialprüfung : Missverständliche Normaussagen ergeben fehlerhafte Nachweise]

The application of the logarithmic normal distribution (LND) in material testing is useful in cases of large variation coefficients. The general task is, to gain from a sample an information of the characteristic value of the tested material property. For that in ge neral the one-sided lower tolerance limit is calculated. German application standards and norms regulate this calculation for the use of the LND not in a correct way - the resulting characteristic values for the regular demanded confidence level of 75 % are too favourable. These calculations do not respect the different distributions with different obliquity of the tested attributes in the sample on one hand and of the mean values of all samples on the other one. This mistake in using the LND is shown in examples. A pragmatic intermediate solution is given, up to the necessary revision in the norms. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG.

Secure cryptographic hash functions are core components in many applications like challenge-response authentication systems or digital signature schemes. Many of these applications are used in cost-sensitive markets and thus slow budget implementations of such components are very important. In the present paper, we focus on the new SHA-3 competition, started by the National Institute of Standards and Technology (NIST), which searches for a new hash function in response to security concerns regarding the previous hash functions SHA-1 and the SHA-2 family. This work adds new valuable data to the competition, by providing an evaluation of area-efficient implementations of all finalists. Our results show, that it is possible to implement all candidates reasonably small. We focus on area-efficiency and therefore we do not rank the candidates by absolute throughput, but rather by the area and the throughput-area ratio. The results hint that Grøstl and Keccak are the best overall performers for compact implementations, if the throughput-area ratio is most important. The following candidate is BLAKE, while the Skein and JH implementations trail behind. The area ranking changes the results and puts JH on the top, followed by BLAKE, Grøstl, Keccak and Skein. © 2011 IEEE.

Corporations are growing more and more international and accordingly need to train and develop an increasingly diverse and dispersed employee based. M-learning seems like it may be the solution if it can cross cultures. Learner initiative has been shown to be a disadvantage of distant learning environments, which would include m-learning. Consequently this study will look at the influence of Hofstede's cultural dimensions on Learner Initiative (LI) and how LI influences technology acceptance of m-learning. A prototype will be designed and shown to representatives of various cultures along the cultural dimension who will then answer a questionnaire. Responses will be evaluated in two phases with the first phase focusing on the cultural influence on LI and the second phase focusing on how LI influences technology acceptance.
