description: Ultrathin freestanding membranes with a pronounced metal-insulator transition (MIT) provides huge potential in future flexible electronic applications as well as a unique aspect of the study of lattice-electron interplay. However, the reduction of the thickness to an ultrathin region (a few nm) is typically detrimental to the MIT in epitaxial films, and even catastrophic for their freestanding form. Here, we report an enhanced MIT in VO2-based freestanding membranes, with a lateral size up to millimetres and VO2 thickness down to 5 nm. The VO2-membranes were detached by dissolving a Sr3Al2O6 sacrificial layer between the VO2 thin film and c-Al2O3(0001) substrate, allowing a transfer onto arbitrary surfaces. Furthermore, the MIT in the VO2-membrane was greatly enhanced by inserting an intermediate Al2O3 buffer layer. In comparison to the best available ultrathin VO2-membranes, the enhancement of MIT is over 400% at 5 nm VO2 thickness and more than one order of magnitude for VO2 above 10 nm. Our study widens the spectrum of functionality in ultrathin and large-scale membranes, and enables the potential integration of MIT into flexible electronics and photonics.

description: This deliverable describes research infrastructures’ prototypes for granting a researcher an authorisation to access research data encouraging secondary use of data that is already collected. This deliverable further describes prototypes for delivering the decision on the granted access rights to the environment that enforces access control. The goal of this deliverable is to document and disseminate existing approaches in contributing research infrastructures.

The main use case in this deliverable is that data access requires authorisation because of its sensitive nature, for instance, if it involves samples from humans. Alternatively, it is possible that the data per se is not sensitive and suited to become public but cannot be shared pending the publication of the research results or filing a patent application. These two use cases are complementary and can be covered by the same technical approaches.

Since this deliverable focuses on accessing research data, access to other kinds of assets (such as, instruments, biological samples and computing capacity) is out of scope. Transfer of research data between datacentres (including legal considerations of cross-national transfers) is also not covered in this deliverable.

This deliverable first presents the key concepts, then previous work in life sciences and beyond as well as within relevant standards bodies (in particular, Global Alliance for Genomics and Health). Finally eight prototype implementations are presented from the contributing research infrastructures, including ELIXIR services for registered and controlled access, BBMRI-ERIC’s Colorectal cancer cohort and Negotiator, EGA’s work on DUO, BBMRI-NL Podium, SOLVE-RD Analysis Sandbox and LifeCycle Federated cohort analysis using DataShield. Before data access authorisation and delivery can be carried out, a researcher needs to be identified and their identity authenticated to a sufficient level of assurance. Existing approaches to researcher authentication are described here to the extent necessary for data access authorisation.

description: The activities of the Pergamon-excavation in 2014 were part of the continuing research program on the urban organism of the Hellenistic residential city and on Pergamon´s countryside. The program also includes studies of the ancient necropolis and the natural sanctuaries as integral elements within the presentation of suburbs and hinterland. The campaign focused on (1) the inner-city survey at the western slope of the city-hill and the western periphery, (2) the excavation of the alleged rock-cut sanctuaries 4 and 2, (3) the excavation within the alleged banquet-building at the northern eastslope, (4) the excavation of the south-eastern necropolis, (5) the archaeological and architectural study of the Lower Agora, (6) the geophysical prospection of large scale gravemounds in the periphery of the ancient city and finally (7) the new Kane-Pensinsula (Kara Dağ) regional harbor survey. The extensive conservation and restoration works have already been presented in a separate report. A detailed preliminary report will be published in “Archäologischer Anzeiger” 2015/2.

description: Using the tools of the J-matrix method, we absorb the 1/r singularity of the Yukawa potential in the reference Hamiltonian, which is handled analytically. The remaining part, which is bound and regular everywhere, is treated by an efficient numerical scheme in a suitable basis using Gauss quadrature approximation. Analysis of resonance energies and bound states spectrum is performed using the complex scaling method, where we show their trajectories in the complex energy plane and demonstrate the remarkable fact that bound states cross over into resonance states by varying the potential parameters.

description: We consider planar rotors (XY spins) in $\mathbb{Z}^d$, starting from an initial Gibbs measure and evolving with infinite-temperature stochastic (diffusive) dynamics. At intermediate times, if the system starts at low temperature, Gibbsianness can be lost. Due to the influence of the external initial field, Gibbsianness can be recovered after large finite times. We prove some results supporting this picture.

The geology and geochemistry of the Daisy Creek Prospect, a stratabound copper-silver occurrence in Western Montana
Creators: name: Stanley, Clifford R.
Publisher: name: University of British Columbia
Year: 2010

description: Stratabound copper, lead, and silver minerals at the Daisy Creek prospect are hosted by crossbedded feldspathic quartzites and orthoquartzites of the Bonner Formation, Missoula Group, Belt Supergroup. Detailed float rock-chip mapping of a 60,000 m² soil grid indicates that mineralization occurs in reduced, coarse grained quartzites, over- and under—lain by fine grained, hematitic quartzites and siltites. Sixty km² regional mapping shows that the prospect lies on the eastern limb of a major broad, open syncline, and that two phases of deformation have folded the strata. Paragenetic relationships in float rock—chips indicate that early diagenetic pyrite was replaced successively by galena, chalcopyrite, and argentiferous bornite and chalcocite. Later, middle diagenetic oxidation resulted in the formation of cupriferous goethite, barite, and acanthite. Holocene supergene oxidation formed abundant malachite, cerrusite, and pyromorphite from these sulfides and earlier oxidation products. Soil grid geochemical anomalies of Cu, Pb, Zn, Ag, Ba, and Hg occur as overlapping zones over the prospect. These geochemical zones overlie and correlate well with areas containing different gossan types. The types of different gossan morphologies and anomalous geochemical concentrations suggest that the zones are mineralogically related and that they are characterized by the presence of galena, chalcopyrite, bornite, and chalcocite. The paragenetic relationships, geochemical soil zoning geometries, gossan morphologies, and geochemical and mineralogical constraints on the mineralization suggest that sulfide deposition occurred before the onset of silica cementation. Furthermore, it involved the introduction of metal-chloride complexed, oxidized ground waters along an aquifer into locally reduced sediments. Diffusion of copper, and later oxygen, from the oxidizing ground waters into the reduced zone resulted in the formation of Cu-sulfides and their subsequent oxidation. A new method of statistical analysis involving the regression of stream sediment data from around the Daisy Creek prospect reveals that the prospect can be precisely located using this technique, and that numerous other 'false anomalies' are recognized. Traditional methods for anomaly recognition fall short of providing the information derived from this technique.

description: Traffic management by applying congestion pricing is a measure for mitigating congestion in protected city corridors. As a promising tool, pricing improves the level of service in a network and reduces travel delays. However, real-world implementations are restricted to static pricing, i.e., the price is fixed and not responsive to the prevailing regional traffic conditions. Dynamic pricing overcomes these limitations but also affects the users route choices. This work uses dynamic pricing's influence and predicts pricing functions to aim for a system optimal traffic distribution. The framework models a large-scale network where every region is considered homogeneous, allowing for the Macroscopic Fundamental Diagram (MFD) application. We compute Dynamic System Optimum (DSO) and a Quasi Dynamic User Equilibrium (QDUE) of the macroscopic model by formulating a linear optimization problem and utilizing the Dijkstra algorithm and a Multinomial Logit model (MNL), respectively. The equilibria allow us to find an optimal pricing methodology by training Multi-Layer-Neural (MLN) network models. We test our framework on a case study in Zurich, Switzerland, and showcase that (a) our neural network model learns the complex user behavior and (b) allows predicting optimal pricing functions. Results show a significant performance improvement when operating a transportation network in the DSO and highlight how dynamic pricing influences the user's route choice behavior towards the system optimal equilibrium.
Mass Loss From Evolved Stars in Elliptical Galaxies

Year: 2008

description: Most of the X-ray emitting gas in early-type galaxies probably originates from red giant mass loss and here we model the interaction between this stellar mass loss and the hot ambient medium. Using two-dimensional hydrodynamic simulations, we adopt a temperature for the ambient medium of 3E6 K along with a range of ambient densities and stellar velocities. When the stellar velocity is supersonic relative to the ambient medium, a bow shock occurs, along with a shock driven into the stellar ejecta, which heats only a fraction of the gas. Behind the bow shock, a cool wake develops but the fast flow of the hot medium causes Kelvin-Helmholtz instabilities to grow and these fingers are shocked and heated (without radiative cooling). Along with the mixing of this wake material with the hot medium, most of the stellar ejecta is heated to approximately the temperature of the hot ambient medium within 2 pc of the star. With the addition of radiative cooling, some wake material remains cool (< 1E5 K), accounting for up to 25% of the stellar mass loss. Less cooled gas survives when the ambient density is lower or when the stellar velocity is higher than in our reference case. These results suggest that some cooled gas should be present in the inner part of early-type galaxies that have a hot ambient medium. These calculations may explain the observed distributed optical emission line gas as well as the presence of dust in early-type galaxies.

description: This paper addresses the numerical simulation of self-piercing rivetting processes to join fibre reinforced polymers and sheet metals. Special emphasis is placed on the modelling of the deformation and failure behaviour of the composite material. Different from the simulation of rivetting processes in metals, which requires the modelling of large plastic deformations, the mechanical response of composites is typically governed by intra- and interlaminar damage phenomena. Depending on the polymeric matrix, viscoelastic effects can interfere particularly with the long-term behaviour of the joint. We propose a systematic approach to the modelling of composite laminates, discuss limitations of the used model, and present details of parameter identification. Homogenisation techniques are applied to predict the mechanical behaviour of the composite in terms of effective anisotropic elastic and viscoelastic material properties. In combination with a continuum damage approach this model represents the deformation and failure behaviour of individual laminae. Cohesive zone elements enable the modelling of delamination processes. The parameters of the latter models are identified from experiments. The defined material model for the composite is eventually utilised in the simulation of an exemplary self-piercing rivetting process.

description: Miletus is a large multi-period site and requires various conservation, restoration and site management projects. In 2012 to 2014 these included the Roman Baths of Faustina, the late Byzantine chapel of Hagia Paraskevi, the ancient theatre and a Byzantine castle on top of it, as well as the ancient street grid and its use by modern visitors. The projects continue a long tradition that goes back to the early 20th century, when Miletus started to be excavated and conserved. Over time, continuous conservation and site management work at Miletus has established local conventions that are easily recognizable, self-explanatory and help the visitor understand a complex settlement including many architectural styles and a wide range of cultures.

description: Using the newly developed real space vortex-lattice based theory of superconductivity, we study the maximum superconducting transition temperature (T_{c}^{\max}) in the iron-based superconductors. We find that all the reported FeAs superconductors can be divided into two basic classes (c/a=3 and c/a=5/2) depending on the lattice constants, where a is the Fe-Fe distance in the xy-plane and c is the Fe-Fe layer distance along the z-axis. Our results suggest that the former class has a maximum T_{c}^{\max}<60K, while the latter class has a lower T_{c}^{\max}\leq 40K. Our investigations further indicate that, in order to enhance T_{c}^{\max} in this family of compounds, new class of superconductors with a larger ratio of c/a should be synthesized. It is likely that their T_{c}^{\max} values could be raised into the liquid nitrogen range (77K) and 100K, supposing the new analogues with c/a=5 (approximately c>13A, if a=2.750A) and c/a=11 (c>31A) can be experimentally achieved, respectively. For the new FeSe series, our mechanism predicts that their T_{c}^{\max} is impossible to exceed 30 K due to a relatively shorter c-axis lattice constant (c/a=2). Finally, based on the new experimental results (arXiv:0811.0094 and arXiv:0811.2205), the possible ways to raise the Tc of the iron-based superconductors into 70 K are also suggested.

The Orpheus Graben, offshore Nova Scotia : palynology, organic geochemistry, maturation and time : temperature history
Creators: name: Lyngberg, Erik
Publisher: name: University of British Columbia
Year: 2010

description: Palynological biostratigraphy and maturation data are combined to reconstruct the burial and thermal history of the Orpheus Graben, offshore Nova Scotia. Palynological analysis indicated that, 1) the age of sediments in the Orpheus Graben range from Upper Triassic to Turonian (Upper Cretaceous) with unconformities occurring in two wells, 2) recycled palynomorphs are ubiquitous in the wells examined, but do not occur in large numbers, 3) the Jurassic section is dominated by Classopollis, indicating an arid environment. The Cretaceous section is dominated by Cyathidites, Taxodiaceapollinites, Gleicheniidites and bisaccate pollen indicating wet tropical or sub-tropical conditions. Maturation zones were determined primarily by spore colour and correlation to vitrinite reflectance and pyrolysis data. Thermally mature rocks occur as shallow as 500 m in one well. The Dawson Canyon and Logan Canyon Formations contain the riches oil prone source rock. Enhanced levels of maturity were found to occur over salt structures. Burial history diagrams are shown for all six wells drilled in the Orpheus Graben as well as burial diagrams for a basin cross section through time. Two models of Tertiary subsidence are considered, 1) with minimal Tertiary deposition, 2) with up to 2000 m of Tertiary deposition. The temperature history of each well drilled in the Orpheus Graben can be inferred by combining the Time-Temperature Index and maturation data. Two temperature distributions are considered, 1) a simple temperature history with geothermal gradients twice the present and up to 2000m of Tertiary deposition and, 2) a complex Temperature history with geothermal gradients up to six times the present with minimal Tertiary deposition. The complex temperature history yields Time-Temperature Index values that are closer to the observed maturity. The future exploration potential is discussed, with enhanced exploration objectives suggested for the region further eastward along the axis of the Orpheus Graben.

description: During the first German excavation period in Didyma a monumental enclosure wall of reused architectural components from the temple of Apollo was erected around the area of the temple, in part as a retaining wall against the higher ground level of the site beyond it. Since the 1970s the wall has been damaged and sections of it collapsed over time. In 2012 a project for investigating, mapping and documenting the condition and damage of this wall was started in preparation for the restoration of collapsed or unstable sections. Since the statics of one section of the wall, 5 metres high, with the terrace of the ‛oracle pension’ above were no longer safe, there was an urgent need to erect a stabilisation-construction of steel which was realised in 2014 by the DAI.

description: Millimeter-wave (mm-wave) is a promising technique to enhance the network capacity and coverage of next-generation (5G) based on utilizing a great number of available spectrum resources in mobile communication. Improving the 5G network requires enhancing and employing mm-wave beamforming channel propagation characteristics. To achieve high data rates, system performance remains a challenge given the impact of propagation channels in mm-wave that is insufficient in both path loss, delay spread, and penetration loss. Additional challenges arise due to high cost and energy consumption, which require combining both analog and digital beamforming (hybrid beamforming) to reduce the number of radio frequency (RF) chains. In this paper, the distributed powers in the small cell to suppress path loss by specifying a considerable power and controlling the distributed power to reduce the high cost and energy consumption was proposed. The hybrid beamforming in mm-wave exploits a large bandwidth which reduces the large path loss in Rayleigh fading channel. Also, the trade-off between the energy consumption of RF chains and cost efficiency depends on reducing the number of RF chains and the distributed number of users. This paper finds that hybrid beamforming for massive multiple-input multiple-output (MIMO) systems constitute a promising platform for advancing and capitalizing on 5G networks

description: A new archaeological project in Carthage studies the last great Roman public monument of the city that has not been extensively excavated so far. The circus of Carthage was, as far as we know, the biggest and most influential of the arenas for chariot racing in North Africa, in size comparable to the Circus Maximus in Rome. The southwestern quarter of ancient Carthage, where the monument is located, furthermore and most importantly offers the possibility to study a large part of the metropolis that has, unlike the rest of the city, not been overbuilt in the modern period. It is the objective of the project to carry out a large scale urbanistic study with a decisively diachronic approach. This article reports on the initial field mission carried out in 2015.

description: We study the entropy of Schwarzschild black holes on DGP brane. The radius of event horizon on DGP brane is obtained by a numerical method. It is smaller than that of Einstein gravity in the conventional branch, and is larger in the accelerated branch. However, the difference is very small. The entropy of the black hole is calculated by using the improved brick-wall method.

description: At least three, possibly even four Early Punic houses have come to light at the Rue Ibn Chabâat site. They followed a north-south orientation and were from the start designed as courtyard houses with a central open area surrounded by rooms of different sizes. While over the course of time minor changes were made to the internal organisation of these housing units, the house plots as well as their orientation remained the same. At the end of the Early Punic period these houses were destroyed when a large building of presumably public character was erected here.
The Fe-Mg solution properties of olivine, enstatite, anthophyllite and talc, from ion-exchange experiments with aqueous chloride solutions

description: Ion-exchange equilibria between a 2molal aqueous Mg-Fe chloride solution and synthetic olivines, orthopyroxenes, orthoamphiboles and talcs have been experimentally bracketed between 450° and 800°C and between 1 and 4kb. Additional experiments at lower chloride molalities reveal that the distribution coefficient measured is dependent upon chloride concentration. Thermodynamic modelling of the chloride solution, assuming ideal mixing of Mg and Fe species, qualitatively reproduces this behavior if the Mg and Fe species have contrasting dissociation constants. Internally consistent thermodynamic properties of all four minerals and the 'delta' properties of a hypothetical associated electrolyte solution are calculated through a combination of linear programming and least-squares optimization while simultaneously considering constraints provided by calorimetry, net-transfer equilibria and other ion-exchange data. Adequate correspondence between thermodynamic model and the data cannot be attained without allowing the mixing of Mg and Fe in the chloride solution to be non-ideal. Qualitative constraints on the chloride 'excess' properties allow a preliminary estimate of the solid solution properties to be made. All solid solutions are modelled with a symmetric Margules formulation. The resulting olivine WG function has a value near 7kJ at 400°C and drops asymptotically toward zero at high temperatures. The orthopyroxene WG is approximately zero at 400°C and drops toward -3kJ at high temperatures. A 'microscopic' orthopyroxene solution model is formulated to be simultaneously consistent with this bulk excess free energy and with measured M1-M2 site distributions. The single WG value (0.58kJ) calculated for the anthophyllite solid solution is qualitatively consistent with fractionation of Fe into M4. The talc solid solution cannot be constrained to be different from ideal by the data presented here. At present, ion-exchange experiments with Mg-Fe chloride solutions can only be used to compare mineral properties due to uncertainties in dissociation constants and 'excess' properties for the aqueous solution. The role of such uncertainties in the data analysis indicates that solid solution properties derived from previous aqueous chloride ion-exchange experiments must be considered suspect until the properties of each pertinent aqueous electrolyte solution have been examined.

description: After Lucius Verus had pushed the Eastern Frontier of the Roman Empire as far east as the Tigris and Khabur rivers, Septimius Severus based two large military garrisons on the route that crosses the Syrian desert following the Euphrates valley. At Dura-Europos the troops moved into the existing Hellenistic- Parthian city and left a rich epigraphic and papyrological evidence whereas at Qreiye-Ayyash they built a new fort, which was documented by fieldwork carried out in 2002–2005.

description: We report photometric estimates of effective temperature, $T_{\rm eff}$, metallicity, [Fe/H], carbonicity, [C/Fe], and absolute carbon abundances, $A{\rm (C)}$, for over 700,000 stars from the Southern Photometric Local Universe Survey (S-PLUS) Data Release 2, covering a substantial fraction of the equatorial Sloan Digital Sky Survey Stripe 82. We present an analysis for two stellar populations: 1) halo main-sequence turnoff stars and 2) K-dwarf stars of mass $0.58 < M/M_{\odot} <0.75$ in the Solar Neighborhood. Application of the Stellar Photometric Index Network Explorer (SPHINX) to the mixed-bandwidth (narrow- plus wide-band) filter photometry from S-PLUS produces robust estimates of the metallicities and carbon abundances in stellar atmospheres over a wide range of temperature, $4250 < T_{\rm eff} \textrm{(K)} < 7000$. The use of multiple narrow-band S-PLUS filters enables SPHINX to achieve substantially lower levels of "catastrophic failures" (large offsets in metallicity estimates relative to spectroscopic determinations) than previous efforts using a single metallicity-sensitive narrow-band filter. We constrain the exponential slope of the Milky Way's K-dwarf halo metallicity distribution function (MDF), $λ_{10, \textrm{[Fe/H]}} = 0.85 \pm 0.21$, over the metallicity range $-2.5 < \textrm{[Fe/H]} < -1.0$; the MDF of our local-volume K-dwarf sample is well-represented by a gamma distribution with parameters $α=2.8$ and $β=4.2$. S-PLUS photometry obtains absolute carbon abundances with a precision of $\sim 0.35$dex for stars with $T_{\rm eff} < 6500$K. We identify 364 candidate carbon-enhanced metal-poor stars, obtain assignments of these stars into the Yoon-Beers morphological groups in the $A$(C)-[Fe/H] space, and derive the CEMP frequencies.

description: The entanglement entropy of a subsystem of a quantum system is expressed, in the replica approach, through analytic continuation with respect to n of the trace of the n-th power of the reduced density matrix. This trace can be thought of as the vacuum expectation value of a suitable observable in a system made with n independent copies of the original system. We use this property to numerically evaluate it in some two-dimensional critical systems, where it can be compared with the results of Calabrese and Cardy, who wrote the same quantity in terms of correlation functions of twist fields of a conformal field theory. Although the two calculations match perfectly even in finite systems when the analyzed subsystem consists of a single interval, they disagree whenever the subsystem is composed of more than one connected part. The reasons of this disagreement are explained.

description: Rotational modulation of stellar light curves due to dark spots encloses information on spot properties and, thus, on magnetic activity. In particular, the decay of the autocorrelation function (ACF) of light curves is presumed to be linked to spot/active-region lifetimes, given that some coherence of the signal is expected throughout their lifetime. In the literature, an exponential decay has been adopted to describe the ACF. Here, we investigate the relation between the ACF and the active-region lifetimes. For this purpose, we produce artificial light curves of rotating spotted stars with different observation, stellar, and spot properties. We find that a linear decay and respective timescale better represent the ACF than the exponential decay. We therefore adopt a linear decay. The spot/active-region timescale inferred from the ACF is strongly restricted by the observation length of the light curves. For 1-year light curves our results are consistent with no correlation between the inferred and the input timescales. The ACF decay is also significantly affected by differential rotation and spot evolution: strong differential rotation and fast spot evolution contribute to a more severe underestimation of the active-region lifetimes. Nevertheless, in both circumstances the observed timescale is still correlated with the input lifetimes. Therefore, our analysis suggests that the ACF decay can be used to obtain a lower limit of the active-region lifetimes for relatively long-term observations. However, strategies to avoid or flag targets with fast active-region evolution or displaying stable beating patterns associated with differential rotation should be employed.

urn:lsid:zoobank.org:act: 83A888D7-740C-4F3A-AEE0-09B56F6FCA92
Type species
Udzungwastreptus marianae Enghoff gen. et sp. nov.
Other included species
None.
Diagnosis
Differs from other trachystreptoform genera by the combination of an unmodified anterior margin of the collum, largely hairless prefemoral lobes of the first pair of male legs, closely appressed to the coxosternum, a ribbon-like free part of the telopodite with a slender accessory lobe branching off ca at midlength, and a simple solenomere originating subapically from the margin of the telopodite.
Etymology
Named after the Udzungwa Mountains, in recognition of their astonishing biological richness; ‘- streptus ’ is a common ending of names of genera of Spirostreptidae, probably derived from the Greek ‘ streptos ’, meaning twisted. Masculine.
Remarks
Udzungwastreptus gen. nov. belongs in group “γ) Télopodite en gouttière ou en bandelette” (telopodite like a gutter or a ribbon) of Demange & Mauriès, 1975. In the key to trachystreptinine genera of Demange & Mauriès (1975), Udzungwastreptus runs to Calostreptus Cook, 1896 with which it shares the lamellate borders of the posttorsal telopodite and the slender solenomere originating from the margin of the telopodite. Also, the prefemoral lobes of the first pair of legs is similar in the two genera (very flat, closely appressed to coxosternum). The new genus differs from Calostreptus as shown in Table 3. See Fig. 24.
