description: In the recent years, the number of detected very high energy (VHE: E > 100 GeV) gamma-ray sources has increased rapidly. The sources have been observed at redshifts up to z = 0.536 without strong indications for the presence of absorption features in the energy spectra. Absorption is however expected due to pair-production processes of the propagating photons with the photon bath in intergalactic space. Even though this photon density is not well known, lower limits can be firmly set by the resolved emission from galaxy counts. Using this guaranteed background light, we investigate the behaviour of the energy spectra in the transition region from the optically thin to the optically thick regime. Among the sample of 50 energy spectra, 7 spectra cover the the range from optical depth $τ< 1$ to $τ> 2$. For these sources, the transition to $τ> 2$ takes place at widely different energies ranging from 0.4 TeV to 21 TeV. Consistently, in all of these sources, an upturn of the absorption-corrected spectrum is visible at this transition with a combined significance of 4.2 standard deviations. Given the broad range of energies and redshifts covered by the sample, source-intrinsic features are unlikely to explain the observed effect. Systematic effects related to observations have been investigated and found to be not sufficient to account for the observed effect. The pair-production process seems to be suppressed in a similar way as expected in the extension of the standard model by a light (

description: Droplet microfluidics (DMF) refers to miniaturized liquid sample handling technology where biological/chemical samples are dispensed and further manipulated in the form of ultrafine droplets (microliter to picoliter), over micro/nano patterned surfaces. Liquid dielectrophoresis (L-DEP) based DMF technology utilizes the pondermotive DEP force, generated as a result of an applied non-uniform electric field, to manipulate aqueous biological and chemical samples. L-DEP offers a rapid and parallel droplet dispensing methodology that is not achieved by other microfluidic droplet dispensing methods. Integrated with Electrowetting/Electrostatic droplet manipulation methods, DEP based DMF devices appear as a plausible alternative to conventional bio-diagnostic equipment. The research project implements specifically designed L-DEP DMF devices to demonstrate versatile handling of homogenous liquid samples, micro-particle suspensions, multi-layered and compartmentalized vesicular assemblies and complex bio-samples/reagents during various experimental observations. Two on-chip, bio-detection assay schemes are first illustrated using synthesized nucleic acid bio-probes. These schemes are: ‘bead-based’ nucleic acid hybridization detection assay and bilayer lipid membrane based nucleic acid isolation/hybridization detection assay. The on-chip, bead based bio-detection method is also implemented to demonstrate a ‘molecular beacon-on-bead’ post amplification detection assay for clinically extracted and amplified Influenza ‘C’ amplicon samples. Numerical analysis is conducted to optimize L-DEP based precision dispensing of functionalized/non-functionalized micro-beads with micro-bead diameter in the range of 1-16 micron, during the on-chip ‘bead-based assays. In order to handle complex bio-samples such as: PCR mix, PCR products and reagents, without excessive sample adsorption, contamination and droplet collapsing, a comprehensive fabrication protocol was developed to generate nano-textured superhydrophobic (SH) surface topology for L-DEP device applications. The static and transient behavior of L-DEP liquid handling over the fabricated SH surface are investigated utilizing an improved lumped model and furthermore experimentally verified using specifically tailored liquid samples. Performance of the developed SH surface is analyzed during liquid actuation of TAQ DNA polymerase enzyme and PCR amplicon products from nucleic acid amplification assays of Influenza viruses. Several new electrode architectures have been designed and have undergone preliminary testing in order to facilitate further development of L-DEP based DMF microfluidic technology, leading towards a microfluidic device that can achieve sample-to-detection bio-diagnostic assays.

description: We have measured the dependence of the hysteretic voltage-induced torsional strain (VITS) in crystals of orthorhombic tantalum trisulfide on temperature and applied torque. In particular, applying square-wave voltages above the charge-density-wave (CDW) threshold voltage, so as to abruptly switch the strain across its hysteresis loop, we have found that the time constant for the VITS to switch (at different temperatures and voltages) varied as the CDW current. Application of torque to the crystal could also change the VITS time constant, magnitude, and sign, suggesting that the VITS is a consequence of residual torsional strain in the sample which twist the CDW. Application of voltage changes the pitch of these CDW twists, which then act back on the lattice. However, it remains difficult to understand the sluggishness of the response.

Machine Learning Involvement in Reservoir Simulation by Optimizing Algorithms in SAGD and SA-SAGD Processes
Creators: name: Zhang, Yu
Publisher: name: Graduate Studies
Year: 2017
Subjects: Engineering--Petroleum

description: Machine learning, as a subset of Artificial Intelligence, has invaded many industries in recent years, thanks to the advancement of the computing power. Over the past decade, the use of machine learning, predictive analytics, and other artificial intelligence-based technologies in the oil and gas industry has grown immensely. Global optimization techniques are useful tools for process optimization and design in various petroleum-engineering disciplines. In this research, the genetic algorithm, one of the global optimization branches, acts as the optimizer for the Steam-Assisted Gravity Drainage (SAGD) process and for the Solvent-Assisted Steam-Assisted Gravity Drainage (SA-SAGD) process. Both binary and continuous encoding techniques that are embedded in a Computer Modeling Group (CMG) simulator STARS perform the primary role to optimize the simulation results. In the end, the comparison with a gradient-based optimization algorithm is studied. The genetic algorithm optimizer coupled with a reservoir simulator is employed to optimize the steam injection rates over the life of a steam-assisted gravity drainage process in a particular reservoir. A concise comparison between the genetic algorithm and a back propagation method discloses the advantages of the genetic algorithm. In the end, the simulation results for various scenarios illustrate the impacts brought by the optimization tool that is coded in programming language Python. The conclusion may be effective in the specific reservoir condition only, though it indicates a worth-trying approach to optimize the SAGD and SA-SAGD operations for various reservoirs.

description: Nearly all of what is known of the patterns of latest Cretaceous and early Paleogene mammalian evolution (from approximately 69 to 57 million years ago) is documented in stratigraphic sequences from the Western Interior of North America. Throughout much of the latest Cretaceous and early Paleogene this region was tectonically active, with the emergence of the Rocky Mountains and Western Interior foreland basin. Several major marine transgressions also occurred during this interval and, at times, the Western Interior epicontinental seaway bisected the continent. Moreover, the latest Cretaceous and early Paleogene is marked by episodes of rapid climatic warming and cooling, and intensive volcanism. That mammals were affected by these changes is without question; however, the extent to which these factors helped shape the evolutionary patterns of this group is less obvious. To better comprehend the evolutionary dynamics between mammals and their environments across this interval, this dissertation focuses on the paleobiogeography of latest Cretaceous through the early Paleogene mammals from the Western Interior of North America. A number of statistical analyses (e.g., ordination, clustering, linear regression) were employed to assess mammalian faunal provinciality within North America during this interval, differences in the relative abundances of fossil mammals during the latest Cretaceous assemblages, and, finally, the latitudinal diversity gradient in latest Cretaceous and early Paleogene mammals. Notable discoveries include the absence of faunal provinciality and little variation in mammalian taxonomic richness across latitude, but considerable differences in the relative abundance of mammals within assemblages from the latest Cretaceous, with eutherians more diverse and abundant in some of the northerly assemblages. These findings suggest that the paleogeographic and climatic changes that characterized the latest Cretaceous and early Paleogene resulted in intricate biogeographic patterns among mammals from this interval. These studies additionally emphasize the importance of quantitatively assessing these patterns to understand the interactions between mammals and their environments.

title: Reports on ICON 005: The Tracer Transport Module Part I - A Mass Consistent Finite Volume Approach with Fractional Steps
Creators: name: Reinert, Daniel
Publisher: name: Deutscher Wetterdienst
Year: 2020

description: The tracer transport module of ICON is presented and the consistency with the continuity equation  for  air  mass  is  discussed.   The  transport  module  solves  the  continuity  equation for tracer mass and, as such, describes the large-scale transport of gaseous, liquid or solid atmospheric constituents due to air motion.  Finite volume methods are applied and combined with  the  fractional  step  approach  (operator  splitting)  in  order  to  derive  mathematically simpler subproblems for the horizontal and vertical directions.  The mathematical derivationof the discretized equation set is presented.  Specific measures are taken in order to achieve consistency with continuity (CWC). These include the reuse of time-averaged mass fluxesfrom the discretized air mass continuity equation, as well as the re-integration of the air masscontinuity equation as part of the fractional step approach.  Results of an ICON forecast run are presented in order to highlight that CWC is maintained, provided that the aforementioned measures are taken.

description: Up to one third of patients with heart failure, who meet the current guidelines for cardiac resynchronization therapy (CRT), do not derive a significant benefit from this device therapy. This thesis explores novel methods to optimize response to CRT, as well as investigates the physiologic mechanisms involved in benefit. Finally, surrogate markers of CRT response are compared to patient important outcomes in a systematic review to understand the relationship. The overarching conclusion is that optimizing CRT response requires individualized pre-implant, implant and post implant considerations.

description: Recent studies have shown that the number counts of convergence peaks N(kappa) in weak lensing (WL) maps, expected from large forthcoming surveys, can be a useful probe of cosmology. We follow up on this finding, and use a suite of WL convergence maps, obtained from ray-tracing N-body simulations, to study (i) the physical origin of WL peaks with different heights, and (ii) whether the peaks contain information beyond the convergence power spectrum P_ell. In agreement with earlier work, we find that high peaks (with amplitudes >~ 3.5 sigma, where sigma is the r.m.s. of the convergence kappa) are typically dominated by a single massive halo. In contrast, medium-height peaks (~0.5-1.5 sigma) cannot be attributed to a single collapsed dark matter halo, and are instead created by the projection of multiple (typically, 4-8) halos along the line of sight, and by random galaxy shape noise. Nevertheless, these peaks dominate the sensitivity to the cosmological parameters w, sigma_8, and Omega_m. We find that the peak height distribution and its dependence on cosmology differ significantly from predictions in a Gaussian random field. We directly compute the marginalized errors on w, sigma_8, and Omega_m from the N(kappa) + P_ell combination, including redshift tomography with source galaxies at z_s=1 and z_s=2. We find that the N(kappa) + P_ell combination has approximately twice the cosmological sensitivity compared to P_ell alone. These results demonstrate that N(kappa) contains non-Gaussian information complementary to the power spectrum.

description: Les catégories littéraires traditionnelles comme la fiction et l’autobiographie tendent à devenir de plus en plus floues. Dans la littérature contemporaine de langue française, l’autofiction connaît une popularité croissante. Pourtant, ce phénomène soulève des questions de classification. Une tendance est de définir l’autofiction comme un genre littéraire, tout en reconnaissant son caractère hybride. Cependant une telle classification peut selon nous se révéler problématique. À travers une analyse de trois textes, ce travail cherche à envisager l’autofiction plutôt comme un procédé littéraire qui mettrait en valeur le projet subjectif de l’auteur. Dans un contexte où chaque auteur s’efforce d’apprivoiser ses conflits internes par l’intermédiaire de son texte, nous nous interrogeons sur l’hybridité et « l’entre-deux » au sens où nous nous demandons si l’autofiction est un phénomène littéraire représentatif de notre temps.

description: The Jewish community of Ulm belonged to the most important Jewish communities of the Late Medieval Empire. This becomes evident from the fact that Jews from Ulm were involved in numerous business and family relations which went far beyond the city of Ulm and stretched over vast areas of Southern Germany; in the 15th century, these relations even reached as far as Northern Italy. The Jewish community of Ulm, moreover, formed the regional centre for several other Jewish settlements in the surrounding area. Based on a large corpus of mainly unedited sources, the study deals with both the inner affairs of the Jewish community and with the various relations Jews from Ulm established with Christians from Ulm and beyond. The analysis shows that the contacts between Jews and Christians in the Middle Ages were by no means limited to exclusion, persecution and expulsion, but that Jews and Christians often lived peacefully door to door and cooperated for mutual benefit.
description: Die Judengemeinde der Reichsstadt Ulm gehörte zu den bedeutendsten jüdischen Gemeinden des spätmittelalterlichen Reiches. Dies kommt darin zum Ausdruck, dass Ulmer Juden in ausgedehnte Geschäfts- und Familienbeziehungen involviert waren, die sich weit über die Stadtmauern Ulms hinaus über den gesamten süddeutschen Raum und im 15. Jahrhundert sogar bis nach Oberitalien erstreckten. Ferner fungierte die Ulmer Judengemeinde als regionales Zentrum für eine Reihe von jüdischen Niederlassungen im städtischen Umfeld. Gestützt auf eine breite Basis meist unedierter Quellen, befasst sich der Autor in seiner Studie sowohl mit den internen Belangen der Ulmer Judengemeinde als auch mit den vielseitigen Kontakten, die Ulmer Juden mit Christen der näheren und weiteren Umgebung unterhielten. Dabei zeigt sich, dass die Berührungspunkte zwischen Juden und Christen im Mittelalter keineswegs auf die Bereiche Ausgrenzung, Verfolgung und Vertreibung zu reduzieren sind, sondern dass Angehörige der beiden Religionsgemeinschaften oftmals über Jahrzehnte hinweg friedlich nebeneinander lebten und zum gegenseitigen Vorteil miteinander kooperierten.

Securitization of Chinese migration in Kazakhstan
Creators: name: Kulsharova, Nazym
Publisher: name: University of British Columbia
Year: 2010

description: Kazakhstan experienced large population in- and outmigration during the first decade after independence. In particular, increased Chinese migration and presence in the country proved to be a focal point for debate for the Kazakhstani public, a fact reflected by the obsessive coverage in the local media. The theory of securitization of security threats is employed to examine the effects of Chinese presence in Kazakhstan and to dissect the varying perceptions of this phenomenon on the state and societal levels. Therefore, the media’s pioneering of the securitization of Chinese migration and the government’s response to it is analyzed in this paper. This paper concludes that though Chinese migration to Kazakhstan constitutes no real security threat to Kazakhstan, however Chinese presence and Chinese migration in Kazakhstan need further research.

description: We report 19 intermediate redshift clusters newly detected in the ROSAT All-Sky survey that are spectroscopically confirmed. They form a part of 911 objects in the REFLEX II cluster catalogue with a limiting flux of 1.8\times10^12 erg/s/cm2 in the 0.1-2.4 keV ROSAT band at redshift z >= 0.2. In addition we report three clusters from the REFLEX III supplementary catalogue, which contains objects below the REFLEX II flux limit but satisfies the redshift constraint above. These clusters are spectroscopically followed-up by our ESO NTT-EFOSC2 campaigns for the redshift measurement. We describe our observing and data reduction methods. We show how X-ray properties such as spectral hardness ratio and source extent can be used as important diagnostics in selecting galaxy cluster candidates. Physical properties of the clusters are subsequently calculated from the X-ray observations. This sample contains the high mass and intermediate-redshift galaxy clusters for astrophysical and cosmological applications.

description: Stellar collapse and the subsequent development of a core-collapse supernova explosion emit bursts of gravitational waves (GWs) that might be detected by the advanced generation of laser interferometer gravitational-wave observatories such as Advanced LIGO, Advanced Virgo, and LCGT. GW bursts from core-collapse supernovae encode information on the intricate multi-dimensional dynamics at work at the core of a dying massive star and may provide direct evidence for the yet uncertain mechanism driving supernovae in massive stars. Recent multi-dimensional simulations of core-collapse supernovae exploding via the neutrino, magnetorotational, and acoustic explosion mechanisms have predicted GW signals which have distinct structure in both the time and frequency domains. Motivated by this, we describe a promising method for determining the most likely explosion mechanism underlying a hypothetical GW signal, based on Principal Component Analysis and Bayesian model selection. Using simulated Advanced LIGO noise and assuming a single detector and linear waveform polarization for simplicity, we demonstrate that our method can distinguish magnetorotational explosions throughout the Milky Way (D

description: In this paper, we show that Minkowski Functionals (MFs) of weak gravitational lensing (WL) convergence maps contain significant non-Gaussian, cosmology-dependent information. To do this, we use a large suite of cosmological ray-tracing N-body simulations to create mock WL convergence maps, and study the cosmological information content of MFs derived from these maps. Our suite consists of 80 independent 512^3 N-body runs, covering seven different cosmologies, varying three cosmological parameters Omega_m, w, and sigma_8 one at a time, around a fiducial LambdaCDM model. In each cosmology, we use ray-tracing to create a thousand pseudo-independent 12 deg^2 convergence maps, and use these in a Monte Carlo procedure to estimate the joint confidence contours on the above three parameters. We include redshift tomography at three different source redshifts z_s=1, 1.5, 2, explore five different smoothing scales theta_G=1, 2, 3, 5, 10 arcmin, and explicitly compare and combine the MFs with the WL power spectrum. We find that the MFs capture a substantial amount of information from non-Gaussian features of convergence maps, i.e. beyond the power spectrum. The MFs are particularly well suited to break degeneracies and to constrain the dark energy equation of state parameter w (by a factor of ~ three better than from the power spectrum alone). The non-Gaussian information derives partly from the one-point function of the convergence (through V_0, the "area" MF), and partly through non-linear spatial information (through combining different smoothing scales for V_0, and through V_1 and V_2, the boundary length and genus MFs, respectively). In contrast to the power spectrum, the best constraints from the MFs are obtained only when multiple smoothing scales are combined.

description: Lipid vesicles are ideal drug delivery carriers due to their small size, biocompatibility, non-toxic behaviour and ability to transport hydrophobic and hydrophilic drugs. Although the mechanism of drug release/uptake following liposome-cell surface contact remains speculative, membrane fusion can occur between the liposome and the cell membrane, thereby releasing the drug. We have previously shown that a general anesthetic (halothane) can be used as a fusion agent in unilamellar vesicles of dioleoylphosphatidylcholine (DOPC).[1] We investigated this new class of fusion agents to better understand the molecular interactions that occur between general anesthetics and membranes and to gain a deeper understanding of the mechanism that describes anesthetic-induced membrane fusion. Fluorescence spectroscopic assays were utilized to determine the kinetics of various stages in the fusion mechanism. We determined that some anesthetics (chloroform, halothane and isoflurane) were able to induce fusion to a greater extent than others (enflurane and sevoflurane). We suggest that an anesthetic’s ability to induce membrane fusion is related to its partition coefficient, aqueous solubility, polarity and size. Our work supports that lipid rearrangement towards the formation of fusion intermediate states as the rate limiting in the fusion mechanism. We studied the transition state dynamics for halothane-induced lipid mixing and obtained values for the activation energy, enthalpy and entropy. Our results suggest that halothane can lower the energy barrier for lipid mixing to a greater extent than other fusion agents previously reported.[2-4] To understand the intricacies of fusion between a drug delivery vehicle and a cell membrane, the systematic determination of the effect each membrane component has on membrane fusion was examined. We found that the addition of cholesterol or dipalmitoylphosphatidylcholine (DPPC) to DOPC vesicles resulted in an overall decrease in the kinetics and the extent of halothane-induced lipid mixing, and therefore membrane fusion. The physical properties of the membrane/presence of membrane domains are suggested to be the main contributing factors directing fusion dynamics. The results presented here increase understanding of how membrane structure and composition influences membrane fusion, which can lead to the development of better fusion agents and/or liposomal drug delivery vehicles.

description: Proteinase-activated receptors (PARs) are a unique subfamily of G-protein coupled receptors (GPCRs), activated by proteolytic processing of their N-terminus to reveal a tethered ligand. The expression of PARs is promiscuous and they play important roles in physiology and pathophysiology. PAR signalling is critical in the regulation of thrombosis, inflammation, and immune function. Diabetes mellitus is a complex metabolic condition characterized by hyperglycaemia, a major pathological factor in the development of diabetic complications. Most of these complications are vascular and involve oxidative stress/inflammatory signalling. We hypothesize that PARs regulate vascular function and that hyperglycaemia-induced changes will change PAR-mediated vascular regulation. Methods: Freshly isolated vascular rings from porcine coronary artery (PCA) and male mouse aorta (MMA) have been used to assess PARs function, while rings cultured in high glucose (HG) were used to study the effect of hyperglycaemia on PAR-mediated signalling. Both contractile and relaxant PAR-mediated responses were assessed in the presence of signal pathway inhibitors using a force displacement bioassay method. Activation of MAPKinase was examined by Western blotting. Results: Activation of PARs 1 & 2 in PCA and MMA induced concentration- and endothelium-dependent relaxations that are not affected by inhibitors of MAPKinase, tyrosine kinases, Rhokinase, or COX, and were entirely NO-mediated in MMA, but NO- and EDHF–dependent in the PCA. On the other hand, activation of PARs 1 & 2 induced endothelium-independent COX-dependent (except for PAR1 in MMA) contractions in both preparations. These contractions were inhibited by inhibitors of EGFR and Src kinases (PAR2 >PAR1 in PCA), MAPKinases, and Rho kinase (only PAR2 in PCA), and by PKC inhibitors (only slightly, PAR2 in PCA). Transactivation of tyrosine kinase signalling was independent of MMPs in the PCA. In addition, high glucose (HG) cultured MMA showed compromised PAR2-mediated relaxations. Catalase, SOD, VAS270 (NADPH oxidase inhibitor), and kinase inhibitors preserved PAR2-relaxation in HG, indicating a role of oxidative stress. Conclusions: PARs regulate vascular endothelial and smooth muscle functions via activation of multiple signalling pathways. Endothelial dysfunction, as a result of HG-induced oxidative stress was manifested as reduced PAR2-mediated relaxations. These results show relevant roles of PAR1 and PAR2 in vascular biology and pathology.

description: In gauge theories the field configurations often occur in distinct topological sectors. In a lattice regularised system with chiral fermions, these sectors can be defined by referring to the Atiyah-Singer Index Theorem. However, if such a model is simulated with local updates of the lattice gauge configuration, the Monte Carlo history tends to get stuck in one sector for many steps, in particular on fine lattices. Then expectation values can be measured only within specific sectors. Here we present a pilot study in the 2-flavour Schwinger model which explores methods of approximating the complete result for an observable - corresponding to a suitable sum over all sectors - based on numerical measurements in a few specific topological sectors. We also probe various procedures for an indirect evaluation of the topological susceptibility, starting from such topologically restricted measurements.

description: We measured the terahertz (THz) complex conductivity of Ca doped YBa_{2}Cu_{3}O_{7-δ} thin films in the frequency range of 0.1 to 3 THz (3 to 100 cm^{-1}) and at a temperature range of 20 to 300 K. The films were measured using both time domain and frequency domain THz methods. We showed evidence for the existence of a sub-gap in overdoped Y_{1-x}Ca_{x}Ba_{2}Cu_{3}O_{7-δ} samples doped with 5% and 10% Ca. Evidence for the opening of this sub-gap appears as a sharp decrease in the spectrum of the real part of conductivity at frequencies equivalent to a gap energy of 1 meV and is more prominent with increased doping. This decrease in conductivity can be explained by using d-wave pairing symmetry with an imaginary part of is or id_{xy} which suggests node removal.

description: In elemental bismuth, emptying the low-index Landau levels is accompanied by giant Nernst quantum oscillations. The Nernst response sharply peaks each time a Landau level intersects the chemical potential. By studying the evolution of these peaks when the field rotates in three perpendicular planes defined by three high-symmetry axes, we have mapped the angle-resolved Landau spectrum of the system up to 12 T. A theoretical model treating electrons at L point with an extended Dirac Hamiltonian is confronted with the experimentally-resolved spectrum. We obtain a set of theoretical parameters yielding a good but imperfect agreement between theory and experiment for all orientations of the magnetic field in space. The results confirm the relevance of the Dirac spectrum to the electron pockets and settle the longstanding uncertainty about the magnitude of the g-factor for holes. According to our analysis, a magnetic field exceeding 2.5 T applied along the bisectrix axis puts all carriers of the three electron pockets in their lowest($j=0$) spin-polarized Landau level. On top of this complex angle-dependent spectrum, experiment detects additional and unexpected Nernst peaks of unidentified origin.

description: This thesis presents the study of atomic cloud density and temperature in a magneto-optical trap (MOT). The purpose is to find the method in obtaining the densest and coldest cloud the setup can produce. In steady state trap, the highest atomic density possible is that of a cloud in multiple scattering regime where a repulsive force between atoms sets a limit to the density. The number of atoms loaded into the trap is controlled by the trapping beam intensity which also changes the temperature. Therefore the trap density and temperature cannot be controlled separately. The cloud compression is studied as a method of increasing atomic density above what is possible in steady state trap without noticeable influence on the cloud temperature. Cloud compression is also found when the cloud is translated by changing the magnetic field zero-point although in a less predictable fashion than the compression.

description: Social Science Japan Data Archive (SSJDA) has been developing DDI implementation projects. We present ongoing projects and some difficulties in the project. Now, users can access more than 1300 datasets and metadata, but those are not based on DDI format. We plan to make metadata in the DDI format (DDI 2.5). But we have some problems with DDI implementation projects. In particular, it is difficult to map between the controlled vocabularies in DDI and some survey methods commonly applied in social surveys in Japan. There are also differences in the granularity of metadata, such as the 'Topic Classification' element. We like to discuss these projects and these difficulties in the project with the EDDI20 participants.
