description: We present a time-resolved photographic analysis of the pulse-to-pulse interaction. In particular, we studied the influence of the cavitation bubble induced by a fs-pulse on the optical focusing of the consecutive pulse and its cavitation bubble dynamics in dependence on temporal pulse separation in water. As a first result, by decreasing the temporal separation of laser pulses, there is a diminishment of the laser-induced optical breakdown (LIOB) efficiency in terms of energy conversion, caused by disturbed focusing into persisting gas bubbles at the focal volume. A LIOB at the focal spot is finally suppressed by impinging the expanding or collapsing cavitation bubble of the preceding pulse. These results could be additionally confirmed in porcine gelatin solution with various concentrations. Hence, the interaction between the laser and transparent ophthalmic tissue may be accompanied by a raised central laser energy transmission, which could be observed in case of a temporal pulse overlap. In conclusion, our experimental results are of particular importance for the optimization of the prospective ophthalmic surgical process with future generation fs-lasers.

description: Photoelectric properties of noncentrosymmetric, similarly oriented metallic nanoparticles embedded in a homogeneous semiconductor matrix are theoretically studied. Because of the asymmetric shape of the nanoparticle boundary, photoelectron emission acquires a preferred direction, resulting in a photocurrent flow in that direction when nanoparticles are uniformly illuminated by a homogeneous plane wave. This effect is a direct analogy of the photogalvanic (or bulk photovoltaic) effect known to exist in media with noncentrosymmetric crystal structure, such as doped lithium niobate or bismuth ferrite, but is several orders of magnitude stronger. Termed the giant plasmonic photogalvanic effect, the reported phenomenon is valuable for characterizing photoemission and photoconductive properties of plasmonic nanostructures and can find many uses for photodetection and photovoltaic applications.

Coronal Thick Target Hard X Ray Emissions and Radio Emissions

description: Recently a distinctive class of hard X ray (HXR) sources located in the corona was found, which implies that the collisionally thick target model (CTTM) applies even to the corona. We investigated whether this idea can independently be verified by microwave radiations that have been known as the best companion to HXRs. The study is made for the GOES M2.3 class flare occurred on 2002 September 9 that were observed by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) and the Owens Valley Solar Array (OVSA). Interpreting the observed energy dependent variation of HXR source size under the CTTM the coronal density should be as high as $5\times 10^{11}$ cm$^{-3}$ over the distance up to 12$"$. To explain the cut-off feature of microwave spectrum at 3 GHz, we however, need density no higher than $1\times 10^{11}$ cm$^{-3}$. Additional constraints need to be placed on temperature and magnetic field of the coronal source in order to reproduce the microwave spectrum as a whole. Firstly, a spectral feature called the Razin suppression requires the magnetic field in a range of 250--350 gauss along with high viewing angles around 75$^{\rm o}$. Secondly, to avoid excess fluxes at high frequencies due to the free-free emission that were not observed, we need a high temperature $\geq2\times 10^7$ K. These two microwave spectral features, Razzin suppression and free-free emissions, become more significant at regions of high thermal plasma density and are essential for validating and for determining additional parameters for the coronal HXR sources.

description: We demonstrate numerically the possibility of multipole interference in the TiO2 (titanium dioxide) microcylinders and microfrustums in the wavelength range 210-300 μm. Resonantly strong destructive interference between toroidal and electric dipole contributions to the scattered field is achieved by a geometry tuning. The toroidal and electric dipole mode overlapping at the resonant wavelength with almost total suppression of the total electric dipole moment is achieved.

description: We perform time-resolved spectroscopy of all the type I bursts from the Rapid Burster (MXB 1730-335) detected with the Rossi X-ray Timing Explorer. Type I bursts are detected at high accretion rates, up to \sim 45% of the Eddington luminosity. We find evidence that bursts lacking the canonical cooling in their time-resolved spectra are, none the less, thermonuclear in nature. The type I bursting rate keeps increasing with the persistent luminosity, well above the threshold at which it is known to abruptly drop in other bursting low-mass X-ray binaries. The only other known source in which the bursting rate keeps increasing over such a large range of mass accretion rates is the 11 Hz pulsar IGR J17480$-$2446. This may indicate a similarly slow spin for the neutron star in the Rapid Burster.

description: This paper gives a review of some recent developments in the field of contactless silicon wafer characterization techniques based on lifetime spectroscopy and infrared imaging. In the first part of the contribution, we outline the status of different lifetime spectroscopy approaches suitable for the identification of impurities in silicon and discussin more detailthe technique of temperature- and injection-dependent lifetime spectroscopy. The second part of the paper focuses on the application of infrared cameras to analyze spatial inhomogeneities in silicon wafers. By measuring the infrared signal absorbed or emitted from light-generated free excess carriers, high-resolution recombination lifetime mappings can be generated within seconds to minutes. In addition, mappings of non-recombination-active trapping centers can be deduced from injection-dependent infrared lifetime images. The trap density has been demonstrated to be an important additional parameter in the characterization and assessment of solar-grade multicrystalline silicon wafers, as areas of increased trap density tend to deteriorate during solar cell processing.
title: The Comparison of Hamstring/Quadriceps Strength Ratio in the Dominant Versus the Non-Dominant Leg of Elite Female Artistic Gymnasts

description: The majority of the injuries in women's artistic gymnastics occur in the lower limbs (Marshall et al, 2007). Hamstring muscle strains are prevalent in sports that involve sprinting (Ekstrand & Quillist, 1985; Orchard, 2001; Croisier et al., 2008) with a high reinjury ratio (Orchard, 1993; Orchard, 1997). Recent studies have linked an increase of muscle injury rate in the lower limbs to strength muscle imbalance between legs and the relation between the hamstring and quadriceps strength (Croisier et al., 2002; Yamamoto, 2008; Sugiura et al, 2008). In order to determine if there is an imbalance in women's artistic gymnastics, forty-three level 9 through elite healthy female gymnasts (12 to 17 years old) were randomly selected from the Hampton Roads gymnastics clubs. The subjects were measured in isometric strength for knee flexion and knee extension. The measurements were taken in seated position with a 45 degrees angle of knee flexion (considering 0° with full knee extension) with a portable fixed dynamometer. The results indicate a significant difference in knee extension quadriceps strength (t42=2.45, p<0.05) between legs. Dominant leg quadriceps peak force (415.89±92.38 newtons) was higher than non-dominant leg quadriceps peak force (387.6-±102.01 newtons). There was also a significant difference when peak force normalized to body weight between limbs was compared (t42=2.77, p<0.05). There was a significant difference in hamstring to quadriceps (H/Q) ratio (as 42=-2.05, p<0.05) between legs. Non-dominant leg H/Q ratio (0. 71±0.14) was 7% higher than dominant leg H/Q ratio (0.66±0.12). No significant difference was found in hamstring peak force. Previous hamstring and knee injuries were reported. The group of previously injured hamstring showed a higher imbalance between limbs in hamstring peak force (9%) than the non-injured group (0.05%). The group that reported previous knee injuries had a higher hamstring peak force and lower quadriceps peak force.
Open Quantum to classical phases transition in the stochastic hydrodynamic analogy: the explanation of the Lindemann relation and the analogies between the maximum of density at He lambda point and that one at water-ice phase transition

description: In the present paper the gas, liquid and solid phases made of structureless particles, are visited to the light of the quantum stochastic hydrodynamic analogy (SQHA). The SQHA shows that the open quantum mechanical behavior is maintained on a distance shorter than the theory-defined quantum correlation length (lc). When, the physical length of the problem is larger than lc, the model shows that the quantum (potential) interactions may have a finite range of interaction maintaining the non-local behavior on a finite distance quantum non-locality length lq. The present work shows that when the mean molecular distance is larger than the quantum non-locality length we have a classical phases (gas and van der Waals liquids) while when the mean molecular distance becomes smaller than lq or than lc we have phases such as the solid crystal or the superfluid one, respectively, that show quantum characteristics. The model agrees with Lindemann empirical law (and explains it), for the mean square deviation of atom from the equilibrium position at melting point of crystal, and shows a connection between the maximum density at the He lambda point and that one near the water-ice solidification point.

description: Low temperature (<400 K) thermoelectric properties of semiconducting RuIn3 and metallic IrIn3 are reported. RuIn3 is a narrow band gap semiconductor with a large n-type Seebeck coefficient at room temperature (S(290K)~400 μV/K), but the thermoelectric Figure of merit (ZT(290K) = 0.007) is small because of high electrical resistivity and thermal conductivity (κ(290 K) ~ 2.0 W/m K). IrIn3 is a metal with low thermopower at room temperature (S(290K)~20 μV/K) . Iridium substitution on the ruthenium site has a dramatic effect on transport properties, which leads to a large improvement in the power factor and corresponding Figure of merit (ZT(380 K) = 0.053), improving the efficiency of the material by an over of magnitude.

We model a volumetric, isotropic source population and incorporate the resulting distribution over signal amplitude, time delay, and coalescence phase into the ranking of candidate events. We describe an improved modeling of the background distribution, and demonstrate incorporating a prior model of the binary mass distribution in the ranking of candidate events. We find an ∼10% and ∼20% increase in detection volume for simulated binary neutron star and neutron star black hole systems, respectively, corresponding to a reduction of the false alarm rates assigned to signals by between one and two orders of magnitude.

description: Current gravitational-wave detectors rely on the use of Michelson interferometers. One crucial limitation of their sensitivity is the thermal noise of their optical components. Thus, for example, fluctuational deformations of the mirror surface are probed by a laser beam being reflected from the mirrors at normal incidence. Thermal noise models are well evolved for that case but mainly restricted to single reflections. In this work, we present the effect of two consecutive reflections under a non-normal incidence onto mirror thermal noise. This situation is inherent to detectors using a geometrical folding scheme such as GEO 600. We revise in detail the conventional direct noise analysis scheme to the situation of non-normal incidence allowing for a modified weighting function of mirror fluctuations. An application of these results to the GEO 600 folding mirror for Brownian, thermoelastic, and thermorefractive noise yields an increase of displacement noise amplitude by 20% for most noise processes. The amplitude of thermoelastic substrate noise is increased by a factor of 4 due to the modified weighting function. Thus, the consideration of the correct weighting scheme can drastically alter the noise predictions and demands special care in any thermal noise design process.

description: For the detailed validation and verification of the capabilities of QBlade-Ocean in work package 2 (WP2) of FLOATECH, a detailed definition of the three considered models was recently presented in Deliverable 2.1 [1]. This document can be seen as a continuation of that work as the three aero-hydro-elastic models within QBlade-Ocean were thoroughly validated against experimental results and other state-of-the-art aero-servo-hydro-elastic simulation codes with complex load cases. As a first check, the models were validated in static and decay tests to assure that their natural frequencies and damping coefficients align. Secondly, regular and irregular wave only load cases were carried out to isolate the hydrodynamic response and quantify the hydrodynamic accuracy of QBlade-Ocean. Finally, combined irregular wave with turbulent wind load cases were analysed in order to obtain insight into the accuracy of QBlade- Ocean in complex load cases where aero-, hydro-, servo- and structural dynamics concurrently play a significant role. Of the simulated models, two include experimental validation: the upscaled 10 MW SOFTWIND experimental turbine mounted on a spar floater and the upscaled 5 MW OC5 experimental turbine mounted on a semi-submersible floater. Both models were additionally set up in the open-source software OpenFAST to, on the one hand, compare the performance of both software tools and on the other hand, as a preparatory step for a full-scale code-to-code comparison with the aim of uncertainty identification between the codes occurring later in WP2. The third model – the DTU 10MW Reference Wind Turbine mounted on the Hexafloat floater – is used for numerical validation against the established commercial code DeepLines Wind™ which was used during the design process of the floater by the company SAIPEM.
 The present document includes results of a selected set of load cases that demonstrate the capabilities of QBlade-Ocean compared to experimental results and the considered numerical codes. Links to the updated QBlade-Ocean models as well as the OpenFAST model are provided in the relevant sections of each model

description: In this paper, we investigate how a sizeable width-to-mass ratio for a gluino, as is for example realized in GMSB scenarios, could affect the discovery potential of gluinos at the LHC. More importantly, the influence of the gluino being "fat" on the standard mass and spin determination methods at the LHC are investigated. For this purpose, we focus on gluino production at the LHC, where we do not factorize the first step in the gluino decay cascade, but treat the following decay cascades step in factorization, including full spin correlations. The effects of sizeable width-to-mass ratios from a few up to 15-20 per cent on the endpoint of several mass determination methods as well as on means for discrimination between BSM spin paradigms like SUSY and UED are studied.

description: The 10 m prototype facility at the Albert-Einstein-institute (AEI) in Hanover, Germany, employs three large seismic attenuation systems to reduce mechanical motion. The AEI seismic-attenuation-system (AEI-SAS) uses mechanical anti-springs in order to achieve resonance frequencies below 0.5 Hz. This system provides passive isolation from ground motion by a factor of about 400 in the horizontal direction at 4 Hz and in the vertical direction at 9 Hz. The presented isolation performance is measured under vacuum conditions using a combination of commercial and custom-made inertial sensors. Detailed analysis of this performance led to the design and implementation of tuned dampers to mitigate the effect of the unavoidable higher order modes of the system. These dampers reduce RMS motion substantially in the frequency range between 10 and 100 Hz in 6 degrees of freedom. The results presented here demonstrate that the AEI-SAS provides substantial passive isolation at all the fundamental mirror-suspension resonances.

description: A detailed validation and verification of the capabilities of QBlade-Ocean is ongoing. Thereby, three wind turbine models mounted on floating substructures with differing characteristics serve as the means for the validation. A detailed description of the models and an initial comparison of results to other state-of-the-art simulation codes is provided in Deliverable 2.1 [1] and 2.2 [2], respectively. This document builds upon the work that is described in the previous deliverables and is the first milestone towards a comprehensive code-to-code comparison and uncertainty quantification study that is being carried out within the work package. In particular, this report acts as a supporting documentation to a dataset containing Floating Offshore Wind Turbine (FOWT) calculations in various design situations, computed with three different codes. In more detail, as presented in Deliverables 2.1 and 2.2, three floating platform archetypes are used in the code-to-code comparison ongoing in work package 2: a semi-submersible-type floater and a spar-type floater as well as the Hexafloat® concept recently proposed by Saipem®. The three test-cases are based on the concepts described in [1]. As presented in the following, two of the three models required adaptations. In fact, during the work leading to Deliverable 2.2, the numerical models were built and tuned to match the characteristic of scaled wave-basin experimental articles. Therefore, some of the assumptions that were made would not be realistic on a full-scale prototype and needed to be changed. The three concepts are simulated in a variety of design load cases (DLCs), as explained in the following. Results of the numerical investigation constitute this dataset.
 The current document acts as a companion description of the dataset of calculations that is provided for the three test cases. In particular, it provides information about the contents of each output, the naming scheme used to identify the different outputs, the Design Load Cases (DLCs) that were simulated and the reference environmental conditions that were used.

Third, put the predictors of phenotype and fitness into an exact equation for evolutionary change, providing a complete expression of selection and other evolutionary processes. The complete expression separates the distinct causal roles of the various hypothesized components of phenotypes and fitness. Traditionally, those components are given by the covariance, variance, and regression terms of evolutionary models. I show how to interpret those statistical expressions with respect to information theory. The resulting interpretation allows one to read the fundamental equations of selection and evolution as sentences that express how various causes lead to the accumulation of information by selection and the decay of information by other evolutionary processes. The interpretation in terms of information leads to a deeper understanding of selection and heritability, and a clearer sense of how to formulate causal hypotheses about evolutionary process. Kin selection appears as a particular type of causal analysis that partitions social effects into meaningful components.

description: Recent observations indicating the existence of a monochromatic gamma-ray line with energy ~130 GeV in the Fermi-LAT data have attracted great interest due to the possibility that the line feature stems from the annihilation of dark matter particles. Many studies examining the robustness of the putative line-signal have concentrated on its spectral attributes. Here, we study the morphological features of the gamma-ray line photons, which can be used to differentiate a putative dark matter signal from astrophysical backgrounds or instrumental artifacts. Photons stemming from dark matter annihilation will produce events tracing a specific morphology, with a statistical clustering that can be calculated based on models of the dark matter density profile in the inner Galaxy. We apply the DBSCAN clustering algorithm to Fermi gamma-ray data, and show that we can rule out the possibility that 1 (2, 4) or fewer point-like sources produce the observed morphology for the line photons at a 99% (95%, 90%) confidence level. Our study strongly disfavors the main astrophysical background envisioned to produce a line feature at energies above 100 GeV: cold pulsar winds. It is highly unlikely that 4 or more such objects have exactly the same monochromatic cosmic-ray energy needed to produce a gamma-ray line, to within instrumental energy resolution. Furthermore, we show that the larger photon statistics expected with Air Cherenkov Telescopes such as H.E.S.S.-II will allow for extraordinarily stringent morphological tests of the origin of the "line photons".

title: Introduction to the Special Issue: Gender and Violence in Contexts of Migration and Displacement
Creators: name: Hofmann, Susanne

description: This special issue originates from the Summer Symposium Reconsidering gender-based violence in the context of displacement and migration held at the Georg-August University of Göttingen on 6-7th July 2017. The working papers explore different forms of gender violence, avoiding the pitfalls of a mainstream feminism that reproduces stereotypes of victimhood and marginalisation. Instead, the authors emphasise the role of power in relation to various kinds of gender violence, paying attention to the intricate inequalities that structure victims’ lives. The authors contribute to intersectional and actor-focused understandings of gender violence in conditions of mobility within or across borders of nation states.

description: We describe a simple extension of the standard model, containing a scalar singlet and a triplet fermion. The model can explain the possible enhancement in the decay $H \rightarrow γγ$ at the LHC together with the excess found in the Higgs boson search at LEP2. The structure of the model is motivated by a recent argument, that was used to explain the number of fermion generations. For the sake of completenes we also considered the contributions from higher multiplets.

Uncertainty Reduction

description: The current document reports the results of the analysis procedure applied to the gathered
 simulation data, according to the following scheme:
  Presentation of significant aggregate data obtained through post-processing of the
 dataset described in [3]. In particular:
 o Global statistics (mean value, maximum and minimum value) of relevant motion
 and load related data;
 o Extreme loads calculated according to standardized procedure (IEC extreme loads
 as described in [4]);
 o Fatigue loads, represented by Damage Equivalent Loads (DELs) for acting on the
 main FOWT components;
  Comparison of the previously reported results between the three codes for each of the
 considered FOWT models;
  Discussion of the outcomes of the comparison, attempting to find, wherever possible,
 reasonable explanations for the differences between codes and quantification the
 uncertainty related to the use of state-of-the-art numerical codes for the prediction of
 FOWTs behaviour.

description: We identify a natural analytic continuation in four dimensions from Minkowski signature to a signature with two time-like momentum components. For two, three and four-point diagrams at fixed external momenta, this continuation can be implemented as a countour deformation that leaves dependence on the momenta unchanged. For arbitrary ultraviolet-finite scalar diagrams it is possible to do two integrals per loop in terms of simple poles in the new signature. This results in a representation of any such diagram as a sum of terms, each with two remaining integrals per loop.

description: A single atom is the prototypical quantum system, and a natural candidate for a quantum bit - the elementary unit of a quantum computer. Atoms have been successfully used to store and process quantum information in electromagnetic traps, as well as in diamond through the use of the NV-center point defect. Solid state electrical devices possess great potential to scale up such demonstrations from few-qubit control to larger scale quantum processors. In this direction, coherent control of spin qubits has been achieved in lithographically-defined double quantum dots in both GaAs and Si. However, it is a formidable challenge to combine the electrical measurement capabilities of engineered nanostructures with the benefits inherent to atomic spin qubits. Here we demonstrate the coherent manipulation of an individual electron spin qubit bound to a phosphorus donor atom in natural silicon, measured electrically via single-shot readout. We use electron spin resonance to drive Rabi oscillations, while a Hahn echo pulse sequence reveals a spin coherence time (T2) exceeding 200 μs. This figure is expected to become even longer in isotopically enriched 28Si samples. Together with the use of a device architecture that is compatible with modern integrated circuit technology, these results indicate that the electron spin of a single phosphorus atom in silicon is an excellent platform on which to build a scalable quantum computer.

Gluino-driven Radiative Breaking, Higgs Boson Mass, Muon $\mathbf{g-2}$, and the Higgs Diphoton Decay in SUGRA Unification

description: We attempt to reconcile seemingly conflicting experimental results on the Higgs boson mass, the anomalous magnetic moment of the muon, null results in search for supersymmetry at the LHC within the 8\TeV data and results from $B$-physics, all within the context of supersymmetric grand unified theories. Specifically, we consider a supergravity grand unification model with non-universal gaugino masses where we take the $\mathrm{SU}(3)_C$ gaugino field to be much heavier than the other gaugino and sfermion fields at the unification scale. This construction naturally leads to a large mass splitting between the slepton and squark masses, due to the mass splitting between the electroweak gauginos and the gluino. The heavy Higgs bosons and Higgsinos also follow the gluino toward large masses. We carry out a Bayesian Monte Carlo analysis of the parametric space and find that it can simultaneously explain the large Higgs mass, and the anomalous magnetic moment of the muon, while producing a negligible correction to the Standard Model prediction for $\mathcal{B}r(B^0_s\toμ^+μ^-)$. We also find that the model leads to an excess in the Higgs diphoton decay rate. A brief discussion of the possibility of detection of the light particles is given. Also discussed are the implications of the model for dark matter.
