description: A complete one-loop prediction for the single production of the neutral Higgs bosons in association with a photon in electron-positron collisions is presented in the framework the minimal supersymmetric standard model (MSSM), paying special attention to the individual contribution from each type of diagram. This process has no amplitude at tree level and is hence directly sensitive to one-loop impacts and the underlying dynamics of Higgs. To investigate the effect of the new physics, four different scenarios, which include a Higgs boson with mass and couplings consistent with those of the discovered Higgs boson and a considerable part of parameter space allowed by the bounds from the searches for additional Higgs bosons and sparticles, are chosen in the MSSM. The dependence of the cross section in both the standard model(SM) and MSSM on the center-of-mass energy is examined by considering the polarizations of the initial electron and positron beams. The effect of individual contributions from each type of one-loop diagram on the total cross section is also investigated in detail. Furthermore, the total cross sections of $e^- e^+ \rightarrow γh^0$ as well as $e^- e^+ \rightarrow γA^0$ are scanned over the plane $m_A-\tanβ$ for each scenario. The full one-loop contributions are crucial for the analysis of beyond the SM physics at a future electron-positron collider.

description: The level of the night sky background light at La Palma and Namibia was determined, with emphasis on the wavelength region and solid angle coverage relevant for the operation of imaging atmospheric Cherenkov telescopes. The dependence of the night sky background light both on celestial coordinates (alt, az) and on galactic coordinates (b, l) was measured, with an angular resolution of about 1 degr. Average light levels near the zenith are similar in both locations -- 2.2 x 10^12 to 2.6 x 10^12 photons per sr s m^2 for 300 nm < lambda < 650 nm. With increasing zenith angle the level of background light increases at La Palma, whereas a constant level is measured in Namibia. Near the center of the Milky Way, background light levels are increased by a factor up to 4 and more. Also the level of light backscattered from the ground has been studied.

description: We demonstrate that the present superaccurate measurements of transition processes between atomic states in hydrogen atom reached the limit of accuracy when transition frequency cannot be defined anymore in a unique way. This was predicted earlier and is due to the necessity to include the nonresonant corrections in the description of resonant processes. The observed spectral line profile becomes asymmetric, and it becomes impossible to extract the value of transition frequency from this profile in a unique way. Nonresonant corrections depend on the type of experiment and on the experimental arrangement. However, the line profile itself for any resonant process can be defined with any desired level of accuracy. A popular trend in modern search for atomic frequency standards and atomic clocks is the search for transitions where the nonresonant corrections are negligible. In this paper we present closed expressions for the resonant photon scattering cross sections on an atomic level with dependence on all atomic quantum numbers including fine and hyperfine structure. These expressions are given for different types of experiments with fixing of the incident (outgoing) photon propagation directions and incident (outgoing) photon polarization. Using these expressions we demonstrate that the transition frequencies in particular cases cannot be derived uniquely if the accuracy of measurement reaches the level quoted in A. Beyer {\it et al}. Our interpretation of the results of this experiment is alternative to the interpretation given by A. Beyer {\it et al}.

description: Low-mass galaxies in nearby clusters are the most numerous galaxy type in the universe, yet their origin and properties remain largely unknown. To study basic questions concerning these galaxies we present the results of a survey designed to constrain the characteristics and properties of the stellar populations in a magnitude complete sample of low-mass cluster galaxies (LMCGs) in the center of the Perseus cluster. Using deep, high-quality WIYN UBR images, we demonstrate that the 53 LMCGs in our sample have a significant scatter about the color-magnitude relationship at M_B > -15. By comparing single-burst stellar population models to our photometry, we argue that stellar populations in LMCGs all have ages > 1 Gyrs, with redder LMCGs having stellar metallicities [Fe/H] > -0.5. By assuming that the colors of LMCGs reflect metallicity, and have co-evolved with the giant ellipticals, we find a wide range of values, from solar to [Fe/H] ~ -3. We argue from this that LMCGs have multiple origins, and fundamentally differ from Local Group dwarf spheroidals/ellipticals. The inferred lower metallicities of the bluer LMCGs implies that these are possibly primordial galaxies formed through self enrichment and stellar feedback provided by winds from supernova. We also investigate several other formation scenarios for these LMCGS, including: self enrichment induced by the confinement of metals in halos by the intracluster medium, in situ formation out of intracluster gas, systems with extreme dark halos, and as remnants of higher mass systems. We conclude that roughly half of all low-mass cluster galaxies have stellar populations and kinematic properties, discussed in previous papers in this series, consistent with being the remnants of stripped galaxies accreted into clusters a few Gyrs ago.

description: Legged animals exhibit diverse locomotion patterns known as gaits, which are capable of robustly traversing terrains of variable grade, roughness, and compliance. Despite the success of legs in nature, wheeled solutions still dominate the field of robotics. State-of-the-art humanoid robots have not yet demonstrated locomotion behaviors that are as robust or varied as their biological counterparts. While humans use a wide range of dynamic motions to ensure stable locomotion, most bipedal robots either reject external
disturbances without changing gait or fall. Modern modelbased control schemes often target individual gaits rather than realizing multiple behaviors within a single framework. Recently, researchers have proposed using the spring mass model as a compliant locomotion paradigm to create unified controllers for walking and running on bipedal systems. Although initial studies have revealed policies capable of transitioning through different gaits, most of these control laws are designed empirically using heuristics.
Furthermore, these controllers have not yet been demonstrated on physical hardware, and thus their utility for real-world machines remains unclear. This thesis investigates the optimal control of simplified bipedal
point-mass models for designing unified walking and running control policies. We examine the theoretically maximum performance these models can achieve and evaluate their utility for controlling higher-order robot hardware. We hypothesize that it is not necessary to hand design these policies using heuristics. Instead, existing numerical optimization tools can generate approximate globally
optimal policies, which can be used to find parametric control laws. We then attempt to transfer these low-dimensional plans onto a physical bipedal robot using a model-based controller to embed the underlying simplified model. We show that this control methodology leads to stable locomotion across several different gaits on the ATRIAS biped robot.

description: We report the discovery of a redshift z=6.56 galaxy lying behind the cluster Abell 370. The object HCM 6A was found in a narrowband imaging survey using a 118 Angstrom bandpass filter centered at 9152 Ang in the LRIS camera on the 10 m Keck II Telescope. Candidate Lyman alpha emitters were identified by the equivalent width of the emission and the absence of lower wavelength flux in ultradeep broadband images. HCM6A is the first galaxy to be confirmed at redshift z>6, and has W_lambda(observed)=190 Angstroms, flux = 2.7 x 10^-17 erg cm^-2 s^-1. Spectra obtained with LRIS confirm the emission line and the continuum break across the line, and show an asymmetric line profile with steep fall-off on the blue side. Deep Subaru near-infrared CISCO images in J, H and K' which extend the sampled continuum to longer wavelengths give a consistent estimate of the continuum flux density in these line-free regions of 2.6+/-0.7 x 10^-30 erg cm^-2 s^-1 Hz^-1. The line width and strength, asymmetric profile, and very deep spectral break are only consistent with the interpretation of the line as a redshifted Lyman alpha feature. From the detailed lensing model of this cluster, we estimate a lensing amplification of 4.5 for this galaxy, which is located slightly over an arcminute from the center of the cluster, for an unlensed flux of 6.5 x 10^-18 erg cm^-2 s^-1. The presence of such a galaxy suggests that the reionizing epoch is beyond z=6.6.

Published for Bulgaria from: present study.
The species is registered in Bulgaria from one locality only (Map 4).
 Researched material and locality (Map 4): South Black Sea Coast: sand coast Arkutino, near by marsh-reserve Arkutino, between Sozopol and Primorsko (NG 58), 2-3 m alt., 72 specimens, 12.09.2005 and 23.06.2006, leg. IRIKOV.
 Shell (Fig. 9): Measurements (n = 72), D: 10.5-16.2 mm, x = 12.4 mm; H: 7.7-12.0 mm, x = 9.0 mm; D/H = 1.3-1.4 mm, x = 1.38 mm.
 Genitalia (Fig. 3): The measurements of some sections of the genitalia are compiled in Table 2 and the variation of the proportions of some sections of the genitalia is represent in Table 3.
 Vertical distribution: In Bulgaria on the Black Sea Coast on several metres of the sea.
 Ecological data: The species live on Black Sea Coast at xerothermal ecological conditions in the summer and comparatively mild and humid winter. There in the same habitat occur M. solidior too, but in difference of her M. ocellata inhabit area more distant of the gritty dunes, where the psamophytic grassy vegetation is a quite abundant. Here perennial plants almost entirely cover the gritty coast. In difference of M. solidior, which rarely may be found to be active on the plants in summertime (see below M. solidior), M. ocellata make huge aggregates among the psamophytic vegetation and in determinate periods the animals are active. In the same locality M. ocellata form the largest aggregates on artificial planted introduced plants of Genus Opuncia sp. These Opuncia occurs in large numbers in nearly located island "Zmiyski Ostrov", where are introduced in the beginning of XX century, and subsequently are carried on the Black Sea Coast.
 We don’t find M. ocellata nowhere elsewhere in the southern Black Sea Coast. We assume that it is possible the species was carried there from the southern areas together with the plants of Genus Opuncia. In the same locality already exist one introduced in the Bulgarian malacofauna species – Cochlicella acuta, reported at first by HUDEC & VASATKO (1973). The manner of introduction is still vague and probably transferring was made accidentally, but the species is survivor and formed small stable population.
Xerophilic, thermophilic, drought-resistant species.

description: We study corner states on a flat band in the square lattice. To this end, we introduce a two dimensional model including Su-Schrieffer-Heeger type bond alternation responsible for corner states as well as next-nearest neighbor hoppings yielding flat bands. The key symmetry of the model for corner states is space-time inversion ($\cal PT$) symmetry, which guarantees quantized Berry phases. This implies that edge states as well as corner states would show up if boundaries are introduced to the system. We also argue that an infinitesimal $\cal PT$ symmetry-breaking perturbation could drive flat bands into flat Chern bands.

description: The calculations of the p-process in the O/Ne layers of Type II supernovae are quite successful in reproducung the solar system content of p-nuclides. They predict, however, a significant underproduction of the rare odd-odd nuclide 138La. A model for the explosion of a 25 Mo star with solar metallicity is used to suggest that electron neutrino captures on 138Ba may well be its most efficient production mechanism. The responsibility of an inadequate prediction of the 138La and 139La photodisintegration rates in the too low production of 138La is also examined quantitatively. A detailed discussion of the theoretical uncertainties in these rates suggest that the required rate changes are probably too high to be fully plausible. Their measurement would be most welcome. They would help disentangling the relative contributions of thermonuclear and neutrino processes to the 138La production.

description: Consider the distances $\tilde{R}_o$ and $R_o$ from the nucleus to a uniformly random point in the 0-cell and the typical cell, respectively, of the $d$-dimensional Poisson-Voronoi (PV) tessellation. The main objective of this paper is to characterize the exact distributions of $\tilde{R}_o$ and $R_o$. First, using the well-known relationship between the 0-cell and the typical cell, we show that the random variable $\tilde{R}_o$ is equivalent in distribution to the contact distance of the Poisson point process. Next, we derive a multi-integral expression for the exact distribution of $R_o$. Further, we derive a closed-form approximate expression for the distribution of $R_o$, which is the contact distribution with a mean corrected by a factor equal to the ratio of the mean volumes of the 0-cell and the typical cell. An additional outcome of our analysis is a direct proof of the well-known spherical property of the PV cells having a large inball.

description: We present a study of the density structure of the protostellar collapse candidate B335 using continuum observations from the IRAM Plateau de Bure Interferometer made at wavelengths of 1.2mm and 3.0mm. We analyze these data, which probe spatial scales from 5000 AU to 500 AU, directly in the visibility domain by comparison to synthetic observations constructed from models that assume different physical conditions. This approach allows for much more stringent constraints to be derived from the data than from analysis of images. A single radial power law in density provides a good description of the data, with best fit power law index p=1.65+/-0.05. Through simulations, we quantify the sensitivity of this result to various model uncertainties, including assumptions of temperature distribution, outer boundary, dust opacity spectral index, and an unresolved central component. The largest uncertainty comes from the unknown presence of a centralized point source. A point source with 1.2mm flux of F=12+/-7 mJy reduces the density index to p=1.47+/-0.07. The remaining sources of systematic uncertainty, the most important of which is the temperature distribution, likely contribute a total uncertainty of < 0.2. We therefore find strong evidence that the power law index of the density distribution within 5000 AU is significantly less than the value at larger radii, close to 2.0 from previous studies of dust emission and extinction. These results conform well to the generic paradigm of isolated, low-mass star formation which predicts a power law density index close to p=1.5 for an inner region of gravitational free fall onto the protostar.

description: In recent times the wind quintet chamber ensemble from the European classical music tradition has incorporated diverse forms of music in its repertoire including the music of Argentinean tango. Despite tango's popularity, only a limited number of arrangements for wind quintet are available. Incorporating diverse forms of music has shown to be an innovative practice in which to expand on the repertoire of European classical music to further sustain and continue its survival as well as providing new and exciting performances for musicians and audiences. This paper discusses the historical background of the wind quintet and the music of Argentinean tango, followed by an analysis of tango's performance practice techniques, yeites, and how these are adapted to the wind quintet. Three tango compositions are then presented to further explore tango's performance mannerisms. This research is important, firstly, as the wind quintet is removed from the cultural context of tango and secondly the manner in which tango is performed is vastly different to its notation on the score. The outcome of this study resulted in my personal wind quintet arrangements of tango compositions for my Master of Music Research degree which were performed with my wind quintet, Liber Winds.

description: $L-$series attached to two classical families of elliptic curves with complex multiplications are studied over number fields, formulae for their special values at $s=1, $ bound of the values, and criterion of reaching the bound are given. Let $ E_1: y^{2}=x^{3}-D_1 x $ be elliptic curves over the Gaussian field $K=\Q(\sqrt{-1}), $ with $ D_1 =π_{1} ... π_{n} $ or $ D_1 =π_{1} ^{2}... π_{r} ^{2} π_{r+1} ... π_{n}$, where $π_{1}, ..., π_{n}$ are distinct primes in $K$. A formula for special values of Hecke $L-$series attached to such curves expressed by Weierstrass $\wp-$function are given; a lower bound of 2-adic valuations of these values of Hecke $L-$series as well as a criterion for reaching these bounds are obtained. Furthermore, let $ E_{2}: y^{2}=x^{3}-2^{4}3^{3}D_2^{2} $ be elliptic curves over the quadratic field $ \Q(\sqrt{-3}) $ with $ D_2 =π_{1} ... π_{n}, $ where $π_{1}, ..., π_{n}$ are distinct primes of $\Q(\sqrt{-3})$, similar results as above but for $3-adic$ valuation are also obtained. These results are consistent with the predictions of the conjecture of Birch and Swinnerton-Dyer, and develop some results in recent literature for more special case and for $2-adic$ valuation.

description: We investigate the evolution of a disk wind into a collimated jet under the influence of magnetic diffusivity, assuming that the turbulent pattern in the disk will also enter the disk corona and the jet. Using the ZEUS-3D code in the axisymmetry option we solve the time-dependent resistive MHD equations for a model setup of a central star surrounded by an accretion disk. We find that the diffusive jets propagate slower into the ambient medium. Close to the star we find that a quasi stationary state evolves after several hundred (weak diffusion) or thousand (strong diffusion) disk rotations. Magnetic diffusivity affects the protostellar jet structure as follows. The jet poloidal magnetic field becomes de-collimated. The jet velocity increases with increasing diffusivity, while the degree of collimation for the hydrodynamic flow remains more or less the same. We suggest that the mass flux is a proper tracer for the degree of jet collimation and find indications of a critical value for the magnetic diffusivity above which the jet collimation is only weak.

description: The bulk flow velocity for the cluster of interstellar cloudlets within about 30 pc of the Sun is determined from optical and ultraviolet absorption line data, after omitting from the sample stars with circumstellar disks or variable emission lines and the active variable HR 1099. Ninety-six velocity components towards the remaining 60 stars yield a streaming velocity through the local standard of rest of -17.0+/-4.6 km/s, with an upstream direction of l=2.3 deg, b=-5.2 deg (using Hipparcos values for the solar apex motion). The velocity dispersion of the interstellar matter (ISM) within 30 pc is consistent with that of nearby diffuse clouds, but present statistics are inadequate to distinguish between a Gaussian or exponential distribution about the bulk flow velocity. The upstream direction of the bulk flow vector suggests an origin associated with the Loop I supernova remnant. Groupings of component velocities by region are seen, indicating regional departures from the bulk flow velocity or possibly separate clouds. The absorption components from the cloudlet feeding ISM into the solar system form one of the regional features. The nominal gradient between the velocities of upstream and downstream gas may be an artifact of the Sun's location near the edge of the local cloud complex. The Sun may emerge from the surrounding gas-patch within several thousand years.

Analysis of the Hipparcos Observations of the Extrasolar Planets and the Brown-Dwarf Candidates

description: We analyzed the Hipparcos astrometric observations of 47 stars that were discovered to harbor giant planets and 14 stars with brown-dwarf secondary candidates. The Hipparcos measurements were used together with the corresponding stellar radial-velocity data to derive an astrometric orbit for each system. To find out the significance of the derived astrometric orbits we applied a "permutation" technique by which we analyzed the permuted Hipparcos data to get false orbits. The size distribution of these false orbits indicated the range of possibly random, false orbits that could be derived from the true data. These tests could not find any astrometric orbit of the planet candidates with significance higher than 99%, suggesting that most if not all orbits are not real. Instead, we used the Hipparcos data to set upper limits on the masses of the planet candidates. The lowest derived upper limit is that of 47UMa - 0.014 solar mass, which confirms the planetary nature of its unseen companion. For 13 other planet candidates the upper limits exclude the stellar nature of their companions, although brown-dwarf secondaries are still an option. These negate the idea that all or most of the extrasolar planets are disguised stellar secondaries. Of the 14 brown-dwarf candidates, our analysis reproduced the results of Halbwachs et al., who derived significant astrometric orbits for 6 systems which imply secondaries with stellar masses. We show that another star, HD164427, which was discovered only very recently, also has a secondary with stellar mass. Our findings support Halbwachs et al. conclusion about the possible existence of the "brown-dwarf desert" which separates the planets and the stellar secondaries.

description: We present a new determination of the time delay of the gravitational lens system HE1104-1805 ('Double Hamburger') based on a previously unpublished dataset. We argue that the previously published value of dt_(A-B)=0.73 years was affected by a bias of the employed method. We determine a new value of dt_(A-B)=0.85+/-0.05 years (2 sigma confidence level), using six different techniques based on non interpolation methods in the time domain. The result demonstrates that even in the case of poorly sampled lightcurves, useful information can be obtained with regard to the time delay. The error estimates were calculated through Monte Carlo simulations. With two already existing models for the lens and using its recently determined redshift, we infer a range of values of the Hubble parameter: Ho=48+/-4 km/s Mpc^-1 (2 sigma) for a singular isothermal ellipsoid (SIE) and Ho=62+/-4 km/s Mpc^-1 (2 sigma) for a constant mass-to-light ratio plus shear model (M/L+gamma). The possibly much larger errors due to systematic uncertainties in modeling the lens potential are not included in this error estimate.

description: The Zeeman interaction is a quantum mechanical effect that underpins spin-based quantum devices such as spin qubits. Typically, identification of the Zeeman interaction needs a large out-of-plane magnetic field coupled with ultralow temperatures, which limits the practicality of spin-based devices. However, in two-dimensional (2D) semiconductor holes, the strong spin-orbit interaction causes the Zeeman interaction to couple the spin, the magnetic field, and the momentum, and has terms with different winding numbers. In this work, we demonstrate a physical mechanism by which the Zeeman terms can be detected in classical transport. The effect we predict is very strong, and tunable by means of both the density and the in-plane magnetic field. It is a direct signature of the topological properties of the 2D hole system, and a manifestation in classical transport of an effect stemming from relativistic quantum mechanics. We discuss experimental observation and implications for quantum technologies.

description: We report first results for the cosmic infrared background (CIB) fluctuations at 1.25, 1.65 and 2.17 micron obtained from long exposures constructed from 2MASS standard star fields. We have co-added and analyzed scans from one such field with a total exposure time > 1 hour, and removed sources and other artifacts. The stars and galaxies were clipped out to K_s~19^m leaving only high-z galaxies (or possibly local low-surface-brightness systems). The residual component of the diffuse emission on scales from a few arc-sec to a few arc-min has a power-law slope consistent with emission produced by clustered galaxies. The noise (and residual artifacts) contribution to the signal is small and the colors of the signal are very different from Galactic stars or air-glow. We therefore identify the signal as CIB fluctuations from the faint unresolved galaxies. We show that the present-day galaxies with no evolution would produce a significant deficit in the observed CIB fluctuations. Thus the dominant contribution to the observed signal must come from high z and may indicate high rates of star formation at those epochs.

description: Objective: To detect the auditory brainstem response (ABR) automatically using an innovative sequentially applied Hotelling’s T 2 test, with the overall goal of optimising test time whilst controlling the false-positive rate (FPR). Design: The stage-wise critical decision boundaries for accepting or rejecting the null hypothesis were found using a new approach called the Convolutional Group Sequential Test (CGST). Specificity, sensitivity, and test time were evaluated using simulations and subject recorded data. Study sample: Data consists of click-evoked ABR threshold series from 12 normal hearing adults, and recordings of EEG background activity from 17 normal hearing adults. Results: Reductions in mean test time of up to 40–45% were observed for the sequential test, relative to a conventional “single shot” test where the statistical test is applied to the data just once. To obtain these results, it will occasionally be necessary to run the test to a higher number of stimuli, i.e. the maximum test time needs to be increased. Conclusions: The CGST can be used to control the specificity of a sequentially applied ABR detection method. Doing so can reduce test time, relative to the “single shot” test, when considered across a cohort of test subjects.

description: Many robotic tasks, such as mobile manipulation, often require interaction with unstructured environments and are subject to imperfect sensing and actuation. This brings substantial uncertainty into the problems. Reasoning
under this uncertainty can provide higher level of robustness but is computationally significantly more challenging. More specifically, sequential decision making under motion and sensing uncertainty can be formulated in a principled form as a Partially Observable Markov Decision Process (POMDP). Solving POMDPs exactly is computationally intractable due to their exponential complexity with the number of states and the depth of the planning horizon, so called, the curse of dimensionality and the curse of
history, respectively. In this work, we propose a novel search-based robust planning framework that sample-efficiently finds a solution with theoretical suboptimality
bounds by leveraging multiple heuristics that are designed using domain knowledge. The main contributions of this work can be summarized as follows: 1) it works with generative models, in the absence of mathematical models, similarly to the reinforcement learning paradigm, but 2) it still exhibits high sample-efficiency by bootstrapping with the domain knowledge in the form of heuristics, and 3) it is empowered with effective guidance of the search toward the goal through the systematic employment of multiple
heuristics. Its solution can be returned in an anytime fashion, and converges to the bounded suboptimality with theoretical guarantees. We validate the proposed frameworks through simulation and robot experiments,
which includes 2D rover navigation, PR2 parts assembly, and full size mobile manipulator truck unloading tasks. The truck unloading task is especially interesting, where the custom-built robot is to unload up to several thousands of boxes from a truck. It is a challenging real-world manipulation problem in continuous space with excessively high uncertainty, and we demonstrate the efficacy of our approach in such a domain.

description: Magnetic frustration in metals is scarce and hard to pinpoint, but exciting due to the possibility of the emergence of fascinating novel phases. The cubic intermetallic compound HoInCu$_4$ with all holmium atoms on an fcc lattice, exhibits partial magnetic frustration, yielding a ground state where half of the Ho moments remain without long-range order, as evidenced by our neutron scattering experiments. The substitution of In with Cd results in HoCdCu$_4$ in a full breakdown of magnetic frustration. Consequently we found a fully ordered magnetic structure in our neutron diffraction experiments. These findings are in agreement with the local energy scales and crystal electric field excitations, which we determined from specific heat and inelastic neutron scattering data. The electronic density of states for the itinerant bands acts as tuning parameter for the ratio between nearest-neighbor and next-nearest-neighbor interactions and thus for magnetic frustration.
Renormalized stress tensor of a quantized massless scalar field in warped cosmological braneworld background

description: Energy momentum tensor of a conformally coupled quantum scalar field in five dimensional warped cosmological spacetimes is studied. We look at situations where the four dimensional part represents a cosmological thick brane and the scale of the extra dimension is time dependent. Renormalization of the components of the energy momentum tensor is achieved using adiabatic regularization method. The resulting energy and pressure densities explicitly show the effects of warping and the dynamic extra dimension on the created matter. We discussed how the created matter may accumulate to form thick branes along the extra dimension.

Ancient Egyptian Hieratic Script - Aspects of Digital Paleography for a NLS

cursive script

description: The project aims to provide an online database and tool for paleographic research of ancient Egyptian cursive scripts (Gülden et al., 2017; Gerhards et al., 2018). In addition to the monumental hieroglyphs, different cursive scripts were used over approximately 3000 years. The so-called Hieratic Script was used for various genres such as literary, religious and administrative texts. Hieratic could be written with ink on papyrus, leather, wooden panels or other materials and even be carved in stone. The approximately 600-700 individual characters of the script can vary immense in their graphical appearance. Until now, there are no satisfactory OCR techniques or any other pattern recognition tools that can be used for hieratic script. Therefore, we need other digital methods and formats to detect similar signs and analyze the script. In the first workshop session, we would like to show the first steps of our workflow beginning with digitizing the ancient Egyptian sources, recording the single signs in the database with links to metadata and in connection to other characters, working our way up to/and ending with preparing the data for digital analysis and a repository.
 In the second part we will present preliminary methods for analyzing raster as well as vector graphics. Furthermore, we would like to discuss the needs of projects that deal with similar paleographic questions of NLS and the possibilities of data structure, analysis, front end visualization and the data repository.

description: Music commands a significant presence in the lives of young adolescents. Earphones ‘housed’ in the adolescent ear are near accessories to everyday life, and smartphones and other portable devices – and the streaming of content they allow access to – afford the opportunity for music to be consumed anywhere at any time. Furthermore, emerging technologies are enabling greater accessibility to music making and production. Students can learn, create and share music using digital technologies alone. Whether it is consumed or produced, music is firmly cemented in adolescent life – it affords a medium for the construction and identification of ‘self’ and the expression of emotion – and is a significant part of the adolescent ‘Being’ (Lines, 2005a). Despite the significant role of music in the lives of adolescents, school music often fails to demand the same attention. It can present a crisis of relevance for the students it proclaims to serve, with student expectations of music and musical experiences offered often existing at considerable remove (Regelski, 2005a; Lines, 2005a; Swanwick, 1999b). This problem is not new – over three decades ago, Paynter (1982) observed that, “music which, outside of school, almost continuously goes in and out of young people’s heads – which stirs their feelings and activates their bodies, becomes when presented – or as presented – inside schools, a ‘dead bore’” (p. vii). For many students, school music education is perceived as unhelpful, irrelevant, even detrimental, to their musical selves.

description: We compute the Brown-Peterson cohomology of QX, the free infinite loop-space on X, when X is a space whose Morava K-theory is flat over its BP-cohomology, in particular a space whose Morava K-theory is concentrated in even degrees. Our computation is in terms of a destabilization functor for BP-cohomology. We also show that for such X, the Morava K-homology of QX is a free commutative algebra.
