description: A massive star can enter the blue supergiant region either evolving directly from the main-sequence, or evolving from a previous red supergiant stage. The fractions of the blue supergiants having different histories depend on the internal mixing and mass-loss during the red supergiant stage. We study the possibility to use diagnostics based on stellar pulsation to discriminate blue supergiants having different evolution histories. For this purpose we have studied the pulsation property of massive star models calculated with the Geneva stellar evolution code for initial masses ranging from 8 to 50 M$_\odot$ with a solar metallicity of $Z=0.014$. We have found that radial pulsations are excited in the blue-supergiant region only in the models that had been red-supergiants before. This would provide us with a useful mean to diagnose the history of evolution of each blue-supergiant. At a given effective temperature, much more nonradial pulsations are excited in the model after the red-supergiant stage than in the model evolving towards the red-supergiant. The properties of radial and nonradial pulsations in blue supergiants are discussed. Predicted periods are compared with period ranges observed in some α-Cygni variables in the Galaxy and NGC 300. We have found that blue supergiant models after the red-supergiant stage roughly agree with observed period ranges in most cases. However, we are left with the puzzle that the predicted surface N/C and N/O ratios seem to be too high compared with those of Deneb and Rigel.

description: With medical advancement and technology, generations are living longer. The process of aging is accompanied by development of chronic disease, reduced physical function, and increased risk of mortality. Older adults do not meet dietary requirements for fruits and vegetables due to lack of access, early satiety, socioeconomic factors, etc. Without proper attainment of fruit and vegetable recommendations, older adults are placed at risk of chronic disease. Interventions exist to help bridge the gap between older adult nutrition and currently established dietary guidelines. Built environments, such as community gardens, have received attentions in the public health arena as a successful way to engage the older adult population with benefits ranging from improved dietary behaviors to increased socializations and improved mental health. Many services for older adults are financially supported through the Older Americans Act. Interventions between community and academic entities require collaborative effort of the researchers at the university, the community members, as well as cooperative extension. Successful interventions engage all levels of the socioeconomic model. Engagement of all program stakeholders as well as clear communication and group collaboration serve as critical necessities in supporting a sustainable intervention of this kind.

description: We model the spacetime of low-mass X-ray binaries with the Tomimatsu-Sato δ = 2 (TS2) metric and study the properties of the orbital and the epicyclic frequencies. The numerical analysis shows that the properties of the characteristic frequencies of oscillation do not differ qualitatively from those of the Kerr black hole. Estimates for the angular momenta of the three stellar mass black hole candidates GRO 1655-40, XTE 1550-564 and GRS 1915+105 are made with the application of the nonlinear resonance model. We find agreement between the predictions based on the 3 : 2 nonlinear resonance model for a TS2 background and the current estimates found in the literature.

description: The biological transformation of added value is seen as one of the key aspects in applied research. Bio- inspired methods and technologies will affect factories of the future and enable them to cope with changing boundary conditions and the rising necessity of sustainability. This results in a higher demand for flexibility and transformation ability of the comprised production systems. To elaborate topics like these, Fraunhofer initiated strategic collaborative research projects. The current project aims at developing aspects of the biological transformation, whereof organic bio-inspired factories is one. Different research focal points were identified as enabling technologies on different levels of the well-established automation pyramid. The paper highlights the aspects “facility layout planning”, “behavioral modeling of production systems” and “skill-based controller programming” as enabling technologies. Solution approaches for the addressed aspects are discussed and future steps towards a flexible and sustainable production are shown.

description: In der vorliegenden Arbeit wurde ein Kühlkörper aus der elektrisch nicht leitenden Keramik Aluminiumnitrid mit einem Kühlkörper aus Aluminium verglichen. Beide Kühlkörper wurden zur Verwendung mit bis zu vier Leistungs-MOSFETs im TO-247-Gehäuse mit einer Wasserkühlung konzipiert. Es konnte gezeigt werden, dass die thermische Leistungsfähigkeit des Aluminiumnitrid-Kühlkörpers mindestens auf dem Niveau des Aluminium-Kühlkörpers liegt. Die Vorteile des Aluminiumnitrid-Kühlkörpers zeigen sich im erheblich geringeren Ableitstrom, da keine Erdung notwendig ist. Dies kann Einsparungen beim Netzfilter ermöglichen, durch welche Bauraum, Masse und Kosten optimiert werden können. Dies kann z. B. für kompakte Wandler auf Galliumnitrid-Basis einen erheblichen Vorteil darstellen, da hier der Netzfilter durch die Common-Mode-Drosseln deutlich mehr Bauraum und Masse beiträgt als die Leistungselektronik selbst. Weiterhin ist es nicht notwendig, eine elektrische Isolierung zwischen MOSFET und Kühlkörper zu verwenden. Auf der anderen Seite wurde festgestellt, dass der Aluminiumnitrid-Kühlkörper die Abstrahlung im Vergleich zu einem geerdeten Kühlkörper in Abhängigkeit von der Systemimpedanz durch eine Verbesserung der Impedanzanpassung erhöhen kann. Auch sind die Herstellungskosten für einen solchen Keramikkühlkörper deutlich höher und die Geometrie ist stark eingeschränkt. Insgesamt stellt der Kühlkörper aus Aluminiumnitrid einen interessanten Ansatz für Systeme dar, welche stark hinsichtlich des Bauraums und der Masse optimiert werden müssen.

description: Auf IC-Ebene ist bei den einstrahlenden EMV-Tests durch bisher fehlende Einstrahlmöglichkeiten mit E-Feld-Orientierung parallel zur Massefläche des ICs eine systematische Testlücke vorhanden. Diese tritt bereits deutlich unter 1 GHz auf, lediglich bei niedrigen Testfrequenzen im unteren MHz-Bereich nicht. Die Situation zur frühzeitigen Erkennung von EMV-Problemen während der IC-Entwicklung ist unzureichend. Im Bericht wurde detailliert dargelegt, ab welchen Frequenzgrenzen diese systematische Testlücke auftritt sowie ein Testaufbau vorgestellt zum Beheben dieser Testlücke bereits auf IC-Ebene.

description: With this work, a novel derivative-free multi-objective optimisation approach for solving engineering problems is presented. State-of-the-art algorithms usually require numerical experimentation in order to tune the algorithm’s multiple parameters to a specific optimisation problem. This issue is effectively tackled by the presented deterministic method which has only a single parameter. The most popular multi-objective optimisation algorithms are based on pseudo-random numbers and need several parameters to adjust the associated probability distributions. Deterministic methods can overcome this issue but have not attracted much research interest in the past decades and are thus seldom applied in practice. The proposed multi-objective algorithm is an extension of the previously introduced deterministic single-objective Global Pattern Search algorithm. It achieves a thorough recovery of the Pareto frontier by tracking a predefined number of non-dominated samples during the optimisation run. To assess the numerical efficiency of the proposed method, it is compared to the well-established NSGA2 algorithm. Convergence is demonstrated and the numerical performance of the proposed optimiser is discussed on the basis of several analytic test functions. Finally, the optimiser is applied to two structural dynamics problems: transfer function estimation and finite element model updating. The introduced algorithm performs well on test functions and robustly converges on the considered practical engineering problems. Hence, this deterministic algorithm can be a viable and beneficial alternative to random-number-based approaches in multi-objective engineering optimisation.

description: The cw ruby laser reveals amazing properties, which have not been expected since its invention 60 years ago. CW pumping with a 405 nm laser diode requires an overall electrical power of only 6 W to achieve more than 100 mW in TEM00 at 694 nm for a linear resonator. In a ring cavity unidirectional single frequency operation with up to 75 mW, tuneable over more than 420 GHz is demonstrated. Experimental details will be presented, and possible applications will be discussed.

description: This review presents the mechanisms for the development of fatigue associated with psychophysical overload. The aim of the work was the analysis of available literature sources touching upon the problem of psychophysical fati-guability. This study was conducted using information retrieval systems (PubMed), as well as databases (eLibrary). Physical exertion experienced by highly skilled athletes, as well as persons in hazardous occupations (divers, astronauts, alpinists), leads to the activation of free radical reactions, CNS disorders, metabolic disorders, oxidative stress,  and mitochondrial dysfunctions, which lead to the development of many different diseases and reduced labor activity. It has been established that the pathogenesis of psychophysical fatigue combines psychomental and musculoskeletal symptoms, by acting upon which, it is possible to reduce the manifestations of fatigue. The analysis of various publica-tions made it possible to establish the key elements of the pathogenesis of this dysfunction with possible ways of its pharmacological correction. Key words: psychophysical fatigue, highly skilled athletes, actoprotectors, oxidative stress, mitochondrial  dysfunction, apoptosis, Metaprot.

description: Entanglement in a quantum system can be demonstrated experimentally by performing the measurements prescribed by an appropriate entanglement witness. However, the unavoidable mismatch between the implementation of measurements in practical devices and their precise theoretical modelling generally results in the undesired possibility of false-positive entanglement detection. Such scenarios can be avoided by using the recently developed device-independent entanglement witnesses (DIEWs) for genuine multipartite entanglement. Similarly to Bell inequalities, DIEWs only assume that consistent measurements are performed locally on each subsystem. No precise description of the measurement devices is required. Here we report an experimental test of DIEWs on up to six entangled 40Ca+ ions. We also demonstrate genuine multipartite quantum nonlocality between up to six parties with the detection loophole closed.

Testing the role of the Barbero-Immirzi parameter and the choice of connection in Loop Quantum Gravity

description: We study the role of the Barbero-Immirzi parameter $γ$ and the choice of connection in the construction of (a symmetry-reduced version of) loop quantum gravity. We start with the four-dimensional Lorentzian Holst action that we reduce to three dimensions in a way that preserves the presence of $γ$. In the time gauge, the phase space of the resulting three-dimensional theory mimics exactly that of the four-dimensional one. Its quantization can be performed, and on the kinematical Hilbert space spanned by SU(2) spin network states the spectra of geometric operators are discrete and $γ$-dependent. However, because of the three-dimensional nature of the theory, its SU(2) Ashtekar-Barbero Hamiltonian constraint can be traded for the flatness constraint of an sl(2,C) connection, and we show that this latter has to satisfy a linear simplicity-like condition analogous to the one used in the construction of spin foam models. The physically relevant solution to this constraint singles out the non-compact subgroup SU(1,1), which in turn leads to the disappearance of the Barbero-Immirzi parameter and to a continuous length spectrum, in agreement with what is expected from Lorentzian three-dimensional gravity.

Impact of anisotropy on the noncritical squeezing properties of two-transverse-mode optical parametric oscillators

description: In a series of articles we studied the quantum properties of a degenerate optical parametric oscillator tuned to the first family of transverse modes at the subharmonic. We found that, for a cavity having rotational symmetry respect to the optical axis, a TEM$_{10}$ mode with an arbitrary orientation in the transverse plane is emitted above threshold. We proved then that quantum noise induces a random rotation of this bright TEM$_{10}$ mode in the transverse plane, while the mode orthogonal to it, the so-called dark mode, has perfect quadrature squeezing irrespective of the distance to threshold (noncritical squeezing). This result was linked to the spontaneous rotational symmetry breaking which occurs when the bright mode is generated, and here we analyze how the squeezing of the dark mode is degraded when the cavity is not perfectly symmetric. We will show that large levels of squeezing are still attainable for reasonable values of this anisotropy, with the advantage that the orientation of the bright and dark modes is basically fixed, a very attractive situation from the experimental point of view.

description: Personalization and adaptation to the user profile capability are the hottest issues to ensure ambient assisted living and context awareness in nowadays environments. With the growing healthcare and wellbeing context aware applications, modeling security policies becomes an important issue in the design of future access control models. This requires rich semantics using ontology modeling for the management of services provided to dependant people. However, current access control models remain unsuitable due to lack of personalization, adaptability and smartness to the handicap situation. In this paper, we propose a novel adaptable access control model and its related architecture in which the security policy is based on the handicap situation analyzed from the monitoring of userss behavior in order to grant a service using any assistive device within intelligent environment. the design of our model is an ontology-learning and evolving security policy for predicting the future actions of dependent people. This is reached by reasoning about historical data, contextual data and user behavior according to the access rules that are used in the inference engine to provide the right service according to the users needs.

description: By combining high spatial resolution and wide-field spectroscopy performed, respectively, with SINFONI and FLAMES at the ESO/VLT we measured the radial velocities of more than 600 stars in the direction of NGC 6388, a Galactic globular cluster which is suspected to host an intermediate-mass black hole. Approximately 55% of the observed targets turned out to be cluster members. The cluster velocity dispersion has been derived from the radial velocity of individual stars: 52 measurements in the innermost 2", and 276 stars located between 18" and 600". The velocity dispersion profile shows a central value of ~13 km/s, a flat behavior out to ~60" and a decreasing trend outwards. The comparison with spherical and isotropic models shows that the observed density and velocity dispersion profiles are inconsistent with the presence of a central black hole more massive than ~2000 Msol. These findings are at odds with recent results obtained from integrated light spectra, showing a velocity dispersion profile with a steep central cusp of 23-25 km/s at r<2" and suggesting the presence of a black hole with a mass of 17,000 Msol (Lutzgendorf et al. 2011). We also found some evidence of systemic rotation with amplitude Arot ~8 km/s in the innermost 2" (0.13 pc), decreasing to Arot= 3.2 km/s at 18"

description: In manufacturing, adherence to delivery dates is one of the main logistic goals. The production control department has to cope with short-term deviations from the planned route sheets. Because of unforeseen disruptions, e.g. machine breakdowns or shortage of material or personnel, in some situations, the promised delivery date to the customer is at stake. In practice, a fast and reasonable decision on how to deal with the delayed order is required. This decision process is often based on a qualitative analysis relying on the planner’s subjective assessment of a complex situation. To improve the quality of possible countermeasures this paper presents an application, which supports the decision process through a quantified analysis using real-time data from business application systems in combination with a simulation of the value stream. The developed app is part of the decision process and estimates the effect of selected countermeasures to accelerate a delayed order. Performance indicators illustrate the effect of the countermeasures on the specific order as well as the whole system. This approach empowers the planner to assess unforeseen situations and aims to improve the quality of the decision-making process. This paper describes the architecture of the application, its simulation ecosystem, the relevant data and the decision process to select the most effective countermeasures.

description: The low temperature thermodynamics of correlated 1D fermionic models with spin and charge degrees of freedom is obtained by exact diagonalization (ED) of small systems and followed by density matrix renormalization group (DMRG) calculations that target the lowest hundreds of states $\{E(N)\}$ at system size $N$ instead of the ground state. Progressively larger $N$ reaches $T < 0.05t$ in correlated models with electron transfer $t$ between first neighbors and bandwidth $4t$. The size dependence of the many-fermion basis is explicitly included for arbitrary interactions by scaling the partition function. The remaining size dependence is then entirely due to the energy spectrum $\{E(N)\}$ of the model. The ED/DMRG method is applied to Hubbard and extended Hubbard models, both gapped and gapless, with $N_e = N$ or $N/2$ electrons and is validated against exact results for the magnetic susceptibility $χ(T)$ and entropy $S(T)$ per site. Some limitations of the method are noted. Special attention is given to the bond-order-wave phase of the extended Hubbard model with competing interactions and low $T$ thermodynamics sensitive to small gaps.

description: Der dritte Band des marxschen Kapitals birgt im Abschnitt zum Bankkapital folgendes Problem: Wie kann das Bankkapital dem Begriff nach den Durchschnittsprofit erzielen, wenn doch der Zins (im ganz allgemeinen Sinne) als Revenue des Bankkapitals immer geringer sein muss als der Durchschnittsprofit? Die vorgeschlagene Lösung argumentiert mit der Unterscheidung von begrenztem und unbegrenztem Kredit. Es wird gezeigt, dass der Begriff des Bankkapitals eine unbegrenzte Seite hat. Ihr Verhältnis zum gesamtgesellschaftlichen Mehrwert wird unter eingeschränkter Bezugnahme auf empirische Oberflächenphänomene reflektiert.

description: We have developed a new experimental setup specifically designed for measuring thermal conductivity on technical superconductors in the range of temperatures from 3 to 330 K in magnetic fields up to 21 T. Three Nb3Sn wires, produced by the powder in tube technique, the bronze route and the internal tin restacked rod process, respectively, have been investigated. We show that, due to the complexity of the architecture of these wires, direct measurement of thermal conductivity is required for a correct estimation of thermal stability in superconducting magnets.

description: We propose high-order FDTD schemes based on the Correction Function Method (CFM) for Maxwell's interface problems with discontinuous coefficients and complex interfaces. The key idea of the CFM is to model the correction function near an interface to retain the order of a finite difference approximation. For this, we solve a system of PDEs based on the original problem by minimizing an energy functional. The CFM is applied to the standard Yee scheme and a fourth-order FDTD scheme. The proposed CFM-FDTD schemes are verified in 2-D using the transverse magnetic mode (TM$_z$). Numerical examples include scattering of magnetic and non-magnetic dielectric cylinders, and problems with manufactured solutions using various complex interfaces and discontinuous piecewise varying coefficients. Long-time simulations are also performed to provide numerical evidences of the stability of the proposed numerical approach. The proposed CFM-FDTD schemes achieve up to fourth-order convergence in $L^2$-norm and provide approximations devoid of spurious oscillations.

Is F-term hybrid inflation natural within minimal supersymmetric SO(10)?

description: We examine whether F-term supersymmetric hybrid inflation can be embedded within the minimal SO(10) model, in a natural way. We show that none of the singlets of the Standard Model symmetries in the minimal set of SO(10) representations can satisfy the conditions which are necessary for a scalar field to play the role of the inflaton. As a consequence, one has to introduce an extra scalar field, which however may spoil the naturalness of inflation within the context of SO(10). Nevertheless, if we add an extra scalar field, we are then able to construct a model that can accommodate flat directions while it preserves the stability of the inflationary valley.

description: The requirements of future production are characterized by increasing demand volatility as well as very short delivery times and high timeliness in the order-based production environment. Furthermore, the trend to customer individual products leads to additional production planning challenges. Therefore, to react fast to these market trends, changeable production networks is a key to success. This technical contribution describes a method for tactical production planning for customer individual products in changeable production networks. The design of the method contains three main process modules (1) order-capability-comparison, (2) capacity planning, and (3) order-specific network structure. Underlying the former described modules, a data model is necessary and introduced. Furthermore, the simulation of the applied system on a prototypical implementation at BSH Hausgeräte GmbH, the largest home appliances manufacturer in Europe, is shown and explained. Finally, limitations are discussed and an outlook into future work for the research field in production planning of production networks is given.
C Language Extensions for Hybrid CPU/GPU Programming with StarPU

description: Modern platforms used for high-performance computing (HPC) include machines with both general-purpose CPUs, and "accelerators", often in the form of graphical processing units (GPUs). StarPU is a C library to exploit such platforms. It provides users with ways to define "tasks" to be executed on CPUs or GPUs, along with the dependencies among them, and by automatically scheduling them over all the available processing units. In doing so, it also relieves programmers from the need to know the underlying architecture details: it adapts to the available CPUs and GPUs, and automatically transfers data between main memory and GPUs as needed. While StarPU's approach is successful at addressing run-time scheduling issues, being a C library makes for a poor and error-prone programming interface. This paper presents an effort started in 2011 to promote some of the concepts exported by the library as C language constructs, by means of an extension of the GCC compiler suite. Our main contribution is the design and implementation of language extensions that map to StarPU's task programming paradigm. We argue that the proposed extensions make it easier to get started with StarPU,eliminate errors that can occur when using the C library, and help diagnose possible mistakes. We conclude on future work.
Experimental determination of gravitomagnetic effects by means of ring lasers
Creators: name: Tartaglia, Angelo
Publisher: name: arXiv
Year: 2012
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A new experiment aimed to the detection of the gravito-magnetic Lense-Thirring effect at the surface of the Earth will be presented; the name of the experiment is GINGER. The proposed technique is based on the behavior of light beams in ring lasers, also known as gyrolasers. A three-dimensional array of ringlasers will be attached to a rigid monument; each ring will have a different orientation in space. Within the space-time of a rotating mass the propagation of light is indeed anisotropic; part of the anisotropy is purely kinematical (Sagnac effect), part is due to the interaction between the gravito-electric field of the source and the kinematical motion of the observer (de Sitter effect), finally there is a contribution from the gravito-magnetic component of the Earth (gravito-magnetic frame dragging or Lense-Thirring effect). In a ring laser a light beam traveling counterclockwise is superposed to another beam traveling in the opposite sense. The anisotropy in the propagation leads to standing waves with slightly different frequencies in the two directions; the final effect is a beat frequency proportional to the size of the instrument and its effective rotation rate in space, including the gravito-magnetic drag. Current laser techniques and the performances of the best existing ring lasers allow at the moment a sensitivity within one order of magnitude of the required accuracy for the detection of gravito-magnetic effects, so that the objective of GINGER is in the range of feasibility and aims to improve the sensitivity of a couple of orders of magnitude with respect to present. The experiment will be underground, probably in the Gran Sasso National Laboratories in Italy, and is based on an international collaboration among four Italian groups, the Technische Universitaet Muenchen and the University of Canterbury in Christchurch (NZ).

description: We present comprehensive multiwavelength observations of three gamma-ray bursts (GRBs) with durations of several thousand seconds. We demonstrate that these events are extragalactic transients; in particular we resolve the long-standing conundrum of the distance of GRB 101225A (the "Christmas-day burst"), finding it to have a redshift z=0.847, and showing that two apparently similar events (GRB 111209A and GRB 121027A) lie at z=0.677 and z=1.773 respectively. The systems show extremely unusual X-ray and optical lightcurves, very different from classical GRBs, with long lasting highly variable X-ray emission and optical light curves that exhibit little correlation with the behaviour seen in the X-ray. Their host galaxies are faint, compact, and highly star forming dwarf galaxies, typical of "blue compact galaxies". We propose that these bursts are the prototypes of a hitherto largely unrecognized population of ultra-long GRBs, that while observationally difficult to detect may be astrophysically relatively common. The long durations may naturally be explained by the engine driven explosions of stars of much larger radii than normally considered for GRB progenitors which are thought to have compact Wolf-Rayet progenitor stars. However, we cannot unambiguously identify supernova signatures within their light curves or spectra. We also consider the alternative possibility that they arise from the tidal disruption of stars by supermassive black holes.

description: Statistical methodology for the design and analysis of clinical Phase II dose response studies, with related software implementation, are well developed for the case of a normally distributed, homoscedastic response considered for a single timepoint in parallel group study designs. In practice, however, binary, count, or time-to-event endpoints are often used, typically measured repeatedly over time and sometimes in more complex settings like crossover study designs. In this paper we develop an overarching methodology to perform efficient multiple comparisons and modeling for dose finding, under uncertainty about the dose-response shape, using general parametric models. The framework described here is quite general and covers dose finding using generalized non-linear models, linear and non-linear mixed effects models, Cox proportional hazards (PH) models, etc. In addition to the core framework, we also develop a general purpose methodology to fit dose response data in a computationally and statistically efficient way. Several examples, using a variety of different statistical models, illustrate the breadth of applicability of the results. For the analyses we developed the R add-on package DoseFinding, which provides a convenient interface to the general approach adopted here.
