description: We consider a modification of the Brans-Dicke gravitational Action Integral inspired by the existence of a minimum length uncertainty for the scalar field. In particular, the kinetic part of the Brans-Dicke scalar field is modified such that the equation of motion for the scalar field be modified according to the quadratic Generalized Uncertainty Principle (GUP). For the background geometry, we assume the homogeneous and isotropic Friedmann--Lema\^ıtre--Robertson--Walker metric. We investigate the dynamics and the cosmological evolution for the dynamical variables of the theory and we compare the results with the unmodified Brans-Dicke theory. It follows that in consideration because of the additional degrees of freedom in the energy-momentum tensor the dynamical variables describe various aspects of the cosmological history. This is one of the first studies on the effects of GUP in a Machian gravitational theory.

description: Work-based learning is driven by the need to learn to do a job. For Graduate Apprenticeships (GAs), which lead to a degree and therefore degree-level roles, the structure of GA programmes needs to be more flexible and the assessment more contextualised in order for apprentices at this level to meet the wide range of needs of graduate employers and vice versa. The expectation is that success in the workplace through learning to do a job, perform a role, undertake a project etc. is driven by deep learning – the need to understand the how and why – rather than the surface learning that is part of the learn, pass, forget cycle that many learners fall into in modular programmes. Graduate Apprentices can learn in the traditional way, but also from other apprentices and other colleagues, and these forms of learning promote thinking and reflection. Traditional academic programmes deliver the same teaching and learning to every learner at the same stage of the programme and assess each learner in the same way, commonly using formal examinations as well as coursework. With work-based learning, because every job role is different, there is the opportunity to provide unique learning and assessment opportunities for each apprentice within the same degree framework. To make work-based learning degrees work, the assessment needs to be made up of activities undertaken in the workplace. Unlike the traditional assessments, these GA assessments won’t be rigid but will be individually tailored to each apprentice based on both course and workplace requirements. This paper discusses how deep learning is embedded in Heriot-Watt University’s Graduate Apprenticeships programmes.

description: Active optics has attracted considerable interest from researchers in synchrotron radiation facilities, because of its capacity for x-ray wavefront correction. Here, we report a novel and efficient technique for correcting or modulating a mirror surface profile based on laser-heating-induced thermal expansion. An experimental study of the characteristics of the surface thermal deformation response indicates that the power of a milliwatt laser yields a bump height as low as sub-nanometer scale, and that variation of the spot size modulates the response function width effectively. In addition, the capacity of the laser-heating technique for free-form surface modulation is demonstrated via a surface correction experiment. The developed method is a promising new approach towards effective x-ray active optics coupled with at-wavelength metrology techniques.

description: The AMADEUS experiment deals with the investigation of the low-energy kaon-nuclei hadronic interaction at the DAΦNE collider at LNF-INFN, which is fundamental to respond longstanding questions in the non-perturbative QCD strangeness sector. The antikaon-nucleon potential is investigated searching for signals from possible bound kaonic clusters, which would open the possibility for the formation of cold dense baryonic matter. The confirmation of this scenario may imply a fundamental role of strangeness in astrophysics. AMADEUS step 0 consisted in the reanalysis of 2004/2005 KLOE dataset, exploiting K- absorptions in H, 4He, 9Be and 12C in the setup materials. In this paper, together with a review on the multi-nucleon K- absorption and the particle identification procedure, the first results on the Σ0-p channel will be presented including a statistical analysis on the possible accomodation of a deeply bound state

description: We present the results of a search for z=9-10 galaxies within the first 8 pointings of the Hubble Frontier Fields (HFF) (4 clusters plus 4 parallel fields) and 20 cluster fields from the CLASH survey. Combined with our previous analysis of the Hubble Ultra-Deep field (HUDF), we have now completed a search for z=9-10 galaxies over ~130 sq. arcmin, across 29 HST WFC3/IR pointings. As in our recent study of the first two HFF fields, we confine our primary search for high-redshift candidates in the HFF imaging to the uniformly deep (i.e. sigma_160>30 AB mag in 0.5-arcsec diameter apertures), relatively low magnification regions. In the CLASH fields our search was confined to uniformly deep regions where sigma_160>28.8 AB mag. Our SED fitting analysis unveils a sample of 33 galaxy candidates at z_phot>=8.4, five of which have primary photometric redshift solutions in the range 9.6=8. We conclude that the data continue to support a smooth decline in rho_UV over the redshift interval 6

description: We apply pseudo-spectral methods to integrate functional flow equations with high accuracy, extending earlier work on functional fixed point equations \cite{Borchardt:2015rxa}. The advantages of our method are illustrated with the help of two classes of models: first, to make contact with literature, we investigate flows of the O$(N)$-model in 3 dimensions, for $N=1, 4$ and in the large $N$ limit. For the case of a fractal dimension, $d=2.4$, and $N=1$, we follow the flow along a separatrix from a multicritical fixed point to the Wilson-Fisher fixed point over almost 13 orders of magnitude. As a second example, we consider flows of bounded quantum-mechanical potentials, which can be considered as a toy model for Higgs inflation. Such flows pose substantial numerical difficulties, and represent a perfect test bed to exemplify the power of pseudo-spectral methods.

description: $μ$ Her is a nearby quadruple system with a G-subgiant primary and several low mass companions arranged in a 2+2 architecture. While the BC components have been well characterized, the Ab component has been detected astrometrically and with direct imaging but there has been some confusion over its nature, in particular whether the companion is stellar or substellar. Using near-infrared spectroscopy we are able to estimate the spectral type of the companion as a M4$\pm$1V star. In addition, we have measured the astrometry of the system for over a decade. We combined the astrometry with archival radial velocity measurements to compute an orbit of the system. From the combined orbit, we are able to compute the mass sum of the system. Using the estimated mass of the primary, we estimate the mass of the secondary as 0.32 M_sun, which agrees with the estimated spectral type. Our computed orbit is preliminary due to the incomplete orbital phase coverage, but it should be sufficient to predict ephemerides over the next decade.

description: Studies involving vortex dynamics and their interaction with pinning centers are an important ingredient to reach higher critical currents in superconducting materials. The vortex distribution around arrays of engineered defects, such as blind and through holes, may help to improve the superconducting properties. Thus, in this work, we used the time-dependent Ginzburg-Landau theory to investigate the vortex dynamics in superconductors of mesoscopic dimensions with a large central square defect with three different configurations: (i) a hole which passes through the sample (interface with the vacuum); (ii) a superconducting region with lower critical temperature (Tc); and (iii) a region with a more robust superconductivity, i.e., with a higherTc. Such systems can be envisaged as elementary building blocks of a macroscopic decorated specimen. Therefore, we evaluated the influence of different interfaces on the vortex dynamics and their effects in the field-dependent magnetization and time-dependent induced electric potential variation. The results show that the lower critical field is independent from the nature of the defect. However, the currents crowd at the vertices of the through hole producing a lower degradation of the local superconductivity, which may increase the upper critical field. On the other hand, the last type of defect can be used to control the vortex dynamics in the main superconducting region around the defect with more accuracy. Whereas the first two defects are attractive for the vortices, the third type is repulsive for them, being needed several vortices penetrated in the superconducting matrix to have vortices penetrated into it.

 Notes:— Hayek (1906) mentioned three collections in the protologue that can be considered as syntypes (Arts. 9.3, 9.5 of the ICN, McNeill et al. 2012). One of these collections was done by Richard Spruce near Pallatanga (Ecuador) in 1858, numbered 5574 (K barcode 000202297 [digital image!], W No. 1889-0294722 [digital image!], W No. 1889- 0166962 [digital image]!). The second was collected in Cauca (Nouvelle Grenade, Colombia today) by J. J. Triana, numbered 2074 (BM barcode 001191075 [digital image!], BM barcode 00119076 [digital image!], G barcode 00382618 [digital image!], P barcode 02886094 [digital image!], W No. 0061990 [digital image!]), and finally the third one was collected in Cauca by H. Karsten, without any collection number (W No. 0061992 [digital image!]).
The specimen collected by H. Karsten is here selected as lectotype because it matches the original description and it is the most complete material (it has flowers and fruits).

description: Nuclear Magnetic Resonance (NMR) spectroscopy is one of the major techniques in structural biology with over 11,800 protein structures deposited in the Protein Data Bank. NMR can elucidate structures and dynamics of small and medium size proteins in solution, living cells, and solids, but has been limited by the tedious data analysis process. It typically requires weeks or months of manual work of a trained expert to turn NMR measurements into a protein structure. Automation of this process is an open problem, formulated in the field over 30 years ago. Here, we present a solution to this challenge that enables the completely automated analysis of protein NMR data within hours after completing the measurements. Using only NMR spectra and the protein sequence as input, our machine learning-based method, ARTINA, delivers signal positions, resonance assignments, and structures strictly without any human intervention. Tested on a 100-protein benchmark comprising 1329 multidimensional NMR spectra, ARTINA demonstrated its ability to solve structures with 1.44 Å median RMSD to the PDB reference and to identify 91.36% correct NMR resonance assignments. ARTINA can be used by non-experts, reducing the effort for a protein assignment or structure determination by NMR essentially to the preparation of the sample and the spectra measurements.

description: Continuous odour measurements both of emissions as well as ambient concentrations are seldom realised, mainly because of their high costs. They are therefore often substituted by concentration measurements of odorous substances. Then a conversion of the chemical concentrations C (mg m-3) into odour concentrations COD (ouE m-3) and odour intensities OI is necessary. Four methods to convert the concentrations of single substances to the odour concentrations and odour intensities of an odorous mixture are investigated: (1) direct use of measured concentrations, (2) the sum of the odour activity value SOAV, (3) the sum of the odour intensities SOI, and (4) the equivalent odour concentration EOC, as a new method. The methods are evaluated with olfactometric measurements of seven substances as well as their mixtures. The results indicate that the SOI and EOC conversion methods deliver reliable values. These methods use not only the odour threshold concentration but also the slope of the Weber-Fechner law to include the sensitivity of the odour perception of the individual substances. They fulfil the criteria of an objective conversion without the need of a further calibration by additional olfactometric measurements.

description: The estimation of physical parameters from data analysis is a crucial point for the description and modeling of many complex systems. Based on Rényi $α$-Gaussian distribution and patched Green's function (PGF) techniques, we propose a robust framework for data inversion using a wave-equation based methodology named full-waveform inversion (FWI). We show the effectiveness of our proposal by considering two distinct realistic P-wave velocity models, in which the first one is inspired in the Kwanza Basin in Angola and the second in a region of great economic interest in the Brazilian pre-salt field. We call our proposal by the abbreviation $α$-PGF-FWI. The results reveal that the $α$-PGF-FWI is robust against additive Gaussian noise and non-Gaussian noise with outliers in the limit $α\rightarrow 2/3$, being $α$ the Rényi entropic index.
Landau-Lifshitz theory of the magnon-drag thermopower

description: Metallic ferromagnets subjected to a temperature gradient exhibit a magnonic drag of the electric current. We address this problem by solving a stochastic Landau-Lifshitz equation to calculate the magnon-drag thermopower. The long-wavelength magnetic dynamics result in two contributions to the electromotive force acting on electrons: (1) An adiabatic Berry-phase force related to the solid angle subtended by the magnetic precession and (2) a dissipative correction thereof, which is rooted microscopically in the spin-dephasing scattering. The first contribution results in a net force pushing the electrons towards the hot side, while the second contribution drags electrons towards the cold side, i.e., in the direction of the magnonic drift. The ratio between the two forces is proportional to the ratio between the Gilbert damping coefficient $α$ and the coefficient $β$ parametrizing the dissipative contribution to the electromotive force.

description: The nearby (6.5 pc) star HD 219134 was recently shown by Motalebi et al. (2015) and Vogt et al. (2015) to host several planets, the innermost of which is transiting. We present twenty-seven years of radial velocity observations of this star from the McDonald Observatory Planet Search program, and nineteen years of stellar activity data. We detect a long-period activity cycle measured in the Ca II $S_{HK}$ index, with a period of $4230 \pm 100$ days (11.7 years), very similar to the 11-year Solar activity cycle. Although the period of the Saturn-mass planet HD 219134 h is close to half that of the activity cycle, we argue that it is not an artifact due to stellar activity. We also find a significant periodicity in the $S_{HK}$ data due to stellar rotation with a period of 22.8 days. This is identical to the period of planet f identified by Vogt et al. (2015), suggesting that this radial velocity signal might be caused by rotational modulation of stellar activity rather than a planet. Analysis of our radial velocities allows us to detect the long-period planet HD 219134 h and the transiting super-Earth HD 219134 b. Finally, we use our long time baseline to constrain the presence of longer-period planets in the system, excluding to $1σ$ objects with $M\sin i>0.36 M_J$ at 12 years (corresponding to the orbital period of Jupiter) and $M\sin i>0.72 M_J$ at a period of 16.4 years (assuming a circular orbit for an outer companion).

description: We study the properties of the Malthusian Toner-Tu theory in its near ordering phase. Because of the birth/death process, characteristic of this Malthusian model, density fluctuations are partially suppressed. We study this model using the perturbative renormalization group. At one loop we find that the renormalization group flow drives the system in an unstable region, suggesting a fluctuation-induced first-order phase transition.

description: Modern numerical simulation techniques allow nowadays obtaining accurate solutions of magnetic pulse and electrohydraulic forming/welding processes. However, one major difficulty persists: the identification of material constitutive equations behavior at levels of high strain rates reached by these processes, and which varies between 103 and 105 s-1. To address this challenge, a direct-impact Hopkinson system was developed at ECN. It permits to perform dynamic tests at very high strain rates exceeding the range of the traditional Split Hopkinson Pressure Bars and hence enable us to identify constitutive models for a wide range of strain rates. The alloy used to test this device was Ti-6Al-4V. Strain rates up to 2.5×103 s-1 were attained.

description: Dissimilar Al/Fe joining was achieved using vaporizing foil actuator welding. Flyer velocities up to 727 m/s were reached using 10 kJ input energy. Four Al/Fe combinations involving AA5052, AA6111-T4, JAC980, and JSC1500 were examined. Weld samples were mechanically tested in lap-shear in three conditions: as-welded, corrosion-tested with ecoating, and corrosion-tested without coating. In all three conditions, the majority of the samples failed in the base aluminium instead of the weld. This shows that the weld was stronger than at least one of the base materials, both before and after corrosion testing. Galvanic corrosion was not significant since the differences in open cell potential, which represent the driving forces for galvanic corrosion, were small among these materials—no more than 60 mV in all cases. Nonetheless, through corrosion testing, the base materials suffered general corrosion, which accounted for the weakening of the base materials.
Menschen mit kognitiver Beeinträchtigung in Spielfilmen - Eine Filmanalyse

Year: 2016
Subjects: subject: 360

description: Die Arbeit untersucht, ob sich Unterschiede in der Darstellung von Menschen mit kognitiver Beeinträchtigung zeigen, wenn die Schauspielerin oder der Schauspieler die Behinderung nur imitiert oder diese selbst besitzt. Dazu wird erforscht, welche Vorstellung von kognitiver Beeinträchtigung in den Spielfilmen vermittelt wird, sowie ob die Beeinträchtigung oder die mögliche Behinderung stereotyp oder stigmatisierend dargestellt werden. Ebenso wird untersucht, welche Bedeutung oder Stellenwert die Beeinträchtigung oder Behinderung hat und was in den Filmen als normal angesehen wird. Zwei Spielfilme, „Einer wie Bruno“ und „Me too – Wer will schon normal sein?“ werden analysiert und verglichen. In „Einer wie Bruno“ wird der Protagonist von einem Schauspieler ohne kognitive Beeinträchtigung gespielt, wohingegen in „Me too“ die Rolle eines Protagonisten mit kognitiver Beeinträchtigung durch einen Schauspieler mit einer solchen Beeinträchtigung verkörpert wird.

description: We report on the measurement and analysis of photoionisation, mass-analysed-threshold-ionisation and pulsed-field-ionisation zero-kinetic-energy photoelectron spectra of HD in the vicinity of the dissociative-ionisation thresholds H$^+$ + D(1s) + e$^-$ and H(1s) + D$^+$ + e$^-$. The spectra were recorded via the $v=11$-13 vibrational levels of the $\bar{\rm H}$ and $\bar{\rm B}$ outer wells of the H$\bar{\rm H}$~$^1Σ_g^+$ and B$^{\prime\prime}\bar{\rm B}$~$^1Σ_u^+$ states and provide information on the weakly bound levels of the X$^+$ $^2Σ_g^+$ ground state of HD$^+$ with vibrational quantum numbers $v^+=16$-21 and rotational angular-momentum quantum numbers $N^+=0$-10. The spectra also reveal for the first time shape and Feshbach resonances of HD$^+$ located energetically above the H$^+$ + D(1s) dissociation limit. The structure and dissociation dynamics of the $\bar{\rm H}$ and $\bar{\rm B}$ states of HD and of the X$^+$ $^2Σ_g^+$ and A$^+$ $^2Σ_u^+$ states of HD$^+$ near the dissociation thresholds are strongly influenced by the g/u-symmetry breaking caused by the nuclear-mass asymmetry.

description: В статье изучена возможность конвейерного использования кормов из разнопоспева-ющих многолетних трав и бобово-злаковых травосмесей с включением новых перспективных сортов трав при их многоукосном использовании. Выявлено, что кормовые сортовые злако-вые и бобовые травы на втором году жизни показали свою эффективность и в полной мере могут применяться для зеленого конвейера в теплый период времени или при заготовке сена на зимний период при стойловом содержании животных. Наилучших показателей урожайно-сти в фазе колошения и бутонизации и цветения достигли позднеспелые травосмеси, а наименьшие показатели во всех фазах оказались у раннеспелых травосмесей.

description: We consider the Cauchy problem for the classical Hirota equation on the line with decaying initial data. Based on the spectral analysis of the Lax pair of the Hirota equation, we first expressed the solution of the Cauchy problem in terms of the solution of a Riemann-Hilbert problem. Further we apply nonlinear steepest descent analysis to obtain the long-time asymptotics of the solution in the critical transition region $|\frac{x}{t} - \frac{α^2}{3β}|t^{2/3} \leq M$, $M$ is a positive constant. Our result shows that the long time asymptotics of the Hirota equation can be expressed in terms of the solution of Painlevé $\mathrm{II}$ equation. Keywords: Hirota equation, steepest descent method, Painlevé $\mathrm{II}$ equation, long-time asymptotics.

Ab initio electronic structure of quasi two-dimensional materials: a "native" gaussian--plane wave approach

description: Ab initio electronic structure calculations of two-dimensional layered structures are typically performed using codes that were developed for three-dimensional structures, which are periodic in all three directions. The introduction of a periodicity in the third direction (perpendicular to the layer) is completely artificial and may lead in some cases to spurious results and to difficulties in treating the action of external fields. In this paper we develop a new approach, which is "native" to quasi-2D materials, making use of basis function that are periodic in the plane, but atomic-like in the perpendicular direction. We show how some of the basic tools of ab initio electronic structure theory -- density functional theory, GW approximation and Bethe-Salpeter equation -- are implemented in the new basis. We argue that the new approach will be preferable to the conventional one in treating the peculiarities of layered materials, including the long range of the unscreened Coulomb interaction in insulators, and the effects of strain, corrugations, and external fields.

description: Financial crises are known as crashes that result in a sudden loss of value of financial assets in large part and they continue to occur from time to time surprisingly. In order to discover features of the financial network, the pairwise interaction of stocks has been considered in many research, but the existence of the strong correlation of stocks and their collective behavior in crisis made us address higher-order interactions. Hence, in this study, we investigate financial networks by triplet interaction in the framework of balance theory. Due to detecting the contribution of higher-order interactions in understanding the complex behavior of stocks we take the advantage of the orders parameters of the higher-order interactions. Looking at real data of financial market obtained from $S\&P500$ through the lens of balance theory for the quest of network structure in different periods of time near and far from crisis reveals the existence of a structural difference of the network that corresponds to different periods of time. Here, we address two well-known crises the Great regression (2008) and the Covid-19 recession (2020). Results show an ordered structure forms on-crisis in the financial network while stocks behave independently far from a crisis. The formation of the ordered structure of stocks in crisis makes the network resistant against disorder. The resistance of the ordered structure against applying a disorder (temperature) can measure the crisis strength and determine the temperature at which the network transits. There is a critical temperature, $T_{c}$, in the language of statistical mechanics and mean-field approach which above, the ordered structure destroys abruptly and a first-order phase transition occurs. The stronger the crisis, the higher the critical temperature.
